The preform of the automatic bottle blowing machine and its heating, pre-blowing (position, pressure and flow), stretching rod, high-pressure blowing (pressure, position) and molds will all affect the production speed of the bottle made by the blowing machine.1. PreformPreform, also known as parison, is injection molded from PET pellets. It requires that the proportion of recycled materials should not exceed 10%, and the number of recycled materials should not exceed twice. Preforms after injection molding or reheated preforms must be cooled for more than 48 hours, and the storage time of the used preforms cannot exceed 6 months. Different production dates, especially preforms with too long distances cannot be mixed. The type of raw material used in the preform, the proportion of the secondary material mixed in and the residual stress in the preform are different, and these factors have a serious impact on the molding process of the bottle blowing bottle, and should be treated in detail according to the actual situation.2. HeatingThe heating of the preform is completed by the heating furnace, which is set manually and adjusted automatically. The height of the heating furnace is preferably about 25mm, and the distance from the delivery wheel is about 19.6mm. The preform runs continuously through the entire oven on the conveying wheel, so that the preform is heated more evenly and can be shaped better, which overcomes the defects of uneven heating caused by static heating and manual rotation in the past. However, if the heating furnace is not adjusted properly, the wall thickness of the blown bottle will be unevenly distributed up and down (for example, the top is light and the bottom is heavy), the bottle mouth will become larger than the standard, hard neck and other product defects, and even cause torsion failure of mechanical parts. The temperature of each area can be adjusted in detail according to the molding status of the product, and at the same time, the opening status of the oven lamp tube should be considered. In addition, the setting of the output power of the oven also has a great influence on the heating of the preform, which controls the heat output of the entire oven. When the pet bottle blowing machine is not turned on for a long time, when it is turned on again, the initial output power should be set higher accordingly, and then gradually reduced to the normal state during normal consumption. The output power is generally about 80%, especially when the ambient temperature is below 5°C. The effect is more significant.The bottle blowing production process also has a certain relationship with the production environment temperature. The ambient temperature is generally room temperature (about 22°C). If the temperature is too high, the product is prone to condensation point agglomeration; if the temperature is too low, the product performance will be unstable when the automatic pet bottle blowing machine is started, and the specific operation should be adjusted according to the actual situation and experience.3. Pre-blowingThe role of pre-blowing in the blowing process is to make the preform take shape, and at the same time, it is stretched longitudinally by the stretching rod to increase its longitudinal strength. The whole process is that the pre-blowing cam pushes the three-way valve to the pre-blowing position during the blowing process, and is completed by the one-way valve. Pre-blowing position, pressure and flow can all affect the quality of the bottle.Position: If the pre-blowing position is advanced, the center point of the bottom of the bottle will be skewed and thinned, the wall thickness of the feet will be uneven and whitish, the top is heavy and the bottom is light, the neck will be hard, and the bottom will penetrate. There will be defects such as light on the top and heavy on the bottom, thickening of the center point, and depression.Air flow The pre-blowing air flow is controlled by a one-way valve, and it is generally advisable to open 3-4 turns. The air flow is large, the bottom is heavy, the center point is thin and biased, the feet are white, and the wall thickness is uneven; the air flow is small, the center point becomes thicker, and the weight of the segment exceeds the standard.Pressure: The pre-blowing pressure is preferably 0.8-1MPa. When the pressure is high, it may cause the top to be heavy and the bottom to be light, the center point is skewed, the wall thickness of the foot is uneven, white, etc.; when the pressure is low, it cannot be fully stretched, the bottom is heavy, and the center point is thick.The shape of the bottle foot and center point has a great influence on the quality of the bottle. Improper adjustment often leads to fatal defects such as bottle bursting (under normal test conditions) and leakage.4. Stretch rodThe stretching rod is a device that stretches the heated preform under the cooperation of pre-blowing at the same time as pre-blowing. It resets after high-pressure blowing and before exhausting. The stretch rod must be able to move vertically and smoothly during the blowing process, the driving pressure is 0.55-0.8MPa, and the gap with the bottom mold is 2.3-2.5mm, that is, the thickness of the preform is 1/3-1/2. If the gap is too large, the center point of the bottom of the bottle will shift; if the gap is too small, the center point will become thinner.5. High pressure blowingThe function of high-pressure blowing is to fully stretch the molten material and cling to the mold wall to fully shape the bottle, and at the same time carry out transverse stretching to improve its transverse strength. The main influencing factors are position and pressure.The high-pressure blowing pressure is generally 3.7-4MPa, which is determined by its molding characteristics and the nature of the filled beverage (carbon dioxide). There are two positions, that is, the position of high-pressure gas and the position of exhaust. The time between the two is the holding time during molding. The length of this time has a great influence on the stability of the bottle capacity. Insufficient high-pressure air can easily cause improper bottle molding and insufficient foot blowing.6. MoldThe mold is one of the important elements affecting the blow molding of the bottle. The body of the bottle is a half mold, and the bottom of the bottle is independent, which is a typical blow mold. During the production process, the mold must be kept at a constant temperature, clean, and the vent hole should be unblocked.When the heating and cooling system of the mold fails, there will be defects such as bottle neck skew, bottle tilt, volume and height changes, and bottom weight; maintaining a constant temperature of the mold can also prevent condensation on the surface of the mold.
1. Problems with automatic blow molding machine parts. The barrel screw of blow molding machine has been used for a long time, and damage gaps have occurred. There are material dead corners in the gaps. During the production process, the previous batch of raw materials of different colors slipped, resulting in continuous color difference problems in the finished product. In this way, it is necessary to check to see the size of the damage problem, and choose to repair or replace the screw.2. The problem of raw materials and color masterbatchControlling raw materials is the key to solving chromatic aberration. If all new materials are used in full and the parameter temperature is well controlled, the color difference of the finished product caused by the raw materials is basically unlikely. If the recycled materials are added, the finished product will appear due to the color value of the recycled materials and uneven stirring during the mixing process. Color difference problem. If adding recycled materials in production, it is necessary to adjust the addition ratio and stirring time according to the performance of recycled materials to ensure uniform raw materials and reduce color difference of finished products. When using color masterbatch, strengthen the inspection of raw material warehousing; in production, the same product should be produced by the same bottle blowing machine manufacturer, masterbatch and color masterbatch of the same brand as much as possible. If it is necessary to change the color masterbatch manufacturer, do a small sample test, and only after meeting the standards can mass production begin.The semi-automatic bottle blowing machine needs to manually remove the flashing, while the automatic plastic blowing machine realizes automation and directly produces the finished product, eliminating the need for labor in the middle to remove the flashing. Labor is saved. In the case of the same energy consumption, energy saving and high efficiency. The product is of good quality and the mouth of the bottle is smooth. There will be no overflow after the cover is put on, which improves the qualified rate of the product. Orders will not be lost because of unqualified products, which will damage the company's reputation. Of course, if your company's product demand is small and you are just starting this industry, you can choose a semi-automatic bottle blowing machine.Everyone may be very familiar with the bottle blowing machine, which is mainly used to blow bottles. The bottle blowing machine mainly blows plastic particles or softened liquids through certain technological means to become what people need. Bottles, compared with other raw materials, plastic hollow containers are not only light in weight and cheap, but also very high in safety. They can be seen everywhere in our lives, especially in various beverage bottles used at home. It is made of plastic, which brings more convenience to people, but what preparations should people make before using the 2l bottle blow molding machine?1. Before using the bottle blowing machine, you should carefully check whether the moving parts are firm, and you should also carefully check whether the screws are loose. If so, you should tighten them in time to ensure safety and stability during use. .2. For places with very strong impact, it is necessary to check whether the belt transmission part is normal and whether there is serious wear and tear. It needs to be replaced and processed, and it is also necessary to add lubricating oil to each part to ensure the service life of the mechanical equipment. longer.Maintenance of the bottle blowing machine in a certain order can not only ensure the normal production of the product, but also prolong the service life of the machine and equipment. Therefore, regarding the maintenance of the bottle blowing machine, the following maintenance rules must be correctly implemented to improve product quality and productivity.1. When the blow molding machine fails, it must be repaired as soon as possible. If it can be repaired during power failure or product replacement operation, it will help reduce downtime and will not delay machine production.2. For the parts that affect the blowing quality of the pet blow molding machine, they need to be replaced or repaired every six months. If there are parts that do not affect the quality of bottle blowing, they can be used for a longer period of time, which can reduce maintenance costs.3. If it is necessary to repair a large area of the blow molding machine, it is best to choose to repair it together when the glass furnace is being repaired, so as to avoid the shutdown of the blow molding machine during the production process.
There are many types of automatic bottle blowing machines. When we use them, we must pay attention to selecting the appropriate model for production.Features of automatic bottle blowing machine:1. Each heating zone is equipped with independent segmental temperature control; the position and distance of the lamp tubes and reflectors in the heating zone can be adjusted according to the different shapes and sizes of preforms to achieve the most ideal heating effect.2. The heating of the preform by the infrared lamp tube is controlled by the constant pressure temperature adjustment method, so as to ensure that the heating of the preform is appropriate, accurate and stable, and will not be affected by the change of the input voltage.3. According to different product needs, this automatic 2l bottle blow molding machine can be equipped with double-cavity double-stretch cylinders, three-cavity three-stretch cylinders, four-cavity four-stretch cylinders or six-cavity six-stretch cylinders. Adjust the use of single-cavity single-drawing cylinder to meet the different needs of machine adjustment or mold trial.4. The control system is equipped with an automatic failure reporting function; when an operation error or failure occurs, the computer will display and issue an alarm.5. The mold replacement is convenient and fast, and there is no need to adjust the thickness of the mold within the mold capacity range of the corresponding machine.6. This automatic blow molding machine is suitable for blowing 30ml-5 liter cold and hot filling plastic bottles or other plastic containers.7. The production process is fully automated, and multiple machines can be combined into a fully automatic production line at the same time. The entire production process does not require manual contact with preforms or finished bottles.Fully automatic high speed blow molding machine is widely used in beverage, medicine, cosmetics, food and chemical industries due to its light weight, low price and high safety. It has attracted many manufacturers to choose plastic containers to replace the previous glass containers. Nowadays, advanced equipment, molds and materials in the plastics industry are all displayed in front of us one by one. New technologies and new applications are emerging one after another. Looking at the field of plastic hollow molding, there are also fruitful results.Fully automatic blow molding machine is a kind of equipment that makes plastic particles into hollow containers through blow molding technology. Now commonly used types of machines include hollow extrusion blow molding machines, injection stretch blow molding machines and newly developed multi-layer hollow extrusion blow molding machines. and stretch blow molding. Most blow molding machines today are still two-step blow molding machines, that is, the plastic material must first be made into preforms and then blown. Nowadays, environmentally friendly plastics made of PET are usually used. One step injection blow molding machine: after the liquid plastic is sprayed out, the wind force blown out by the machine is used to blow the plastic body to a mold cavity of a certain shape, and then make a product. This kind of machine is called a blow molding machine. The blow molding machine is also a type of blow molding machine, that is, the hydraulic blow molding machine.The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is added to the split mold while it is hot, and compressed air is injected into the parison immediately after the mold is closed, so that the plastic parison is inflated and clings to the inner wall of the mold. After cooling and demoulding, various hollow products can be obtained.
