Blow molding machine is a kind of equipment that makes plastic pellets into hollow containers through blow molding process. There are two common ones at present, one is a one-time molding hollow extrusion blowing machine using PP and PE, and the other is using PET. , PC or PP two-step injection stretch blow molding machine. Two-step bottle blowing machine is widely used in carbonated beverage bottles, mineral water bottles, cosmetic bottles, edible oil bottles, pesticide bottles, large-diameter bottles, high-temperature resistant bottles and other packaging containers of any shape with crystalline plastics such as PET and PP as raw materials. . For many people who are new to the plastic bottle industry, they need to know and learn a lot before purchasing, and they need to buy according to their own needs. The more expensive blow molding machine is of course the better, but it may not be suitable for you. Because there are many types of blow molding machines, they are generally divided into semi-automatic blow molding machines, hand-plugged automatic blow molding machines, and fully automatic blow molding machines. Taizhou Runrun Machinery Co., Ltd. can customize according to customers' different output and bottle capacity. Now briefly talk about the two steps in the production of the two-step blow molding machine. 1. Preheating The preform is irradiated by an infrared high-temperature lamp, and the body part of the preform is heated and softened. In order to maintain the shape of the bottle mouth, the preform mouth does not need to be heated, so a certain cooling device is required to cool it. . 2. Bottle blow molding In this stage, the preheated preform is placed in the finished blow mold, and the stretching rod is stretched out for high-pressure inflation, and the preform is blown and drawn into the desired bottle shape. Features of semi-automatic bottle blowing machine: 1. It can blow 0.1-5 liter PET bottles (one out of two), 5L-20L (single cavity) 2. Use a mold with two cavities to blow 500 ml bottles and the output per hour can be 3. Advanced PLC control system, time control can be accurate to 0.01 seconds 4. Special air storage device 5. The use of infrared lamps for heating, strong penetration, preform rotation heating, orbital revolution, heating evenly, Fast and reliable 6. Different heating lamps are equipped with independent temperature control devices to ensure the ideal heating effect of the preforms 7. The direction of the heating lamps can be adjusted according to different preforms 8. Only one person is required to operate, no special 9. Installation and start-up are simple 10. The scrap rate of finished products is less than 0.1%. The automatic blow molding machine does not require manual operation. The output has different models of 2000-8000 bottles per hour. Features: A. Adopt advanced microcomputer control system, Stable performance; B. The conveyor automatically feeds the blank; C. The infrared lamp is used for heating, with strong penetrating power, the preform is heated by the rotation, and the orbit revolves, and the heating is uniform, fast and reliable; D. The lamp and reflector in the heating area The width and height can be adjusted to suit the heating of preforms with different structures, and there is an automatic temperature discharge device to ensure the constant temperature of the drying tunnel; E. Each mechanical action has a safety self-locking device, when a certain process occurs In case of failure, the program will automatically switch to a safe state; F. Each action is driven by an oil pump, which has the advantages of no pollution and low noise; Different air pressure requirements; H. Adopt high pressure and double crank arm connecting rod for clamping, and the clamping force is strong; I. There are manual and automatic operation methods; J. Safe, reliable and unique valve position design, it is more The road becomes clear at a glance; K. The production process is all automated, which has the advantages of low investment, high efficiency, convenient operation, simple maintenance, and safety. L. The bottle body is free from pollution. M. The cooling system achieves the ideal cooling effect. N. Installation and simple start-up.
is emerging as one of the most popular bottle blowing machine, moving beyond its pet bottle machine price benefits, with conclusive scientific evidence suggesting the positive role play in pet bottle manufacturing machine.
