Common faults and solutions of automatic blow molding machines

The automatic bottle blowing machine does not require manual operation, but the automatic bottle blowing machine will inevitably fail. Xiaobian combines the common problems of the market and its own equipment to share the common faults and solutions of the automatic bottle blowing machine for your reference. . (1) The bottom molding is not full Reasons: 1. The blowing pressure is not enough 2. The temperature of the preform during blowing is slightly lower Solution: 1. Check whether the high-pressure filter on the side of the mold is unobstructed 2. Check the working condition of the road valve to ensure the blowing The positioning of the air is accurate 3. Check the air flow control element of the air blow to ensure the correct setting value and the interior is unobstructed 4. Make sure that all the ventilation holes on the mold are not blocked (2) Reasons for neck bending: 1. The neck is caused by mechanical operation. The solution to the deformation after the mold is closed due to the excessive thickness of the accumulated material: 1. Optimize the mold clamping structure. 2. The convex ring is too tightly clamped in the recess of the mold top plate, and the size of the preform must be fixed when it is still hot. (3) Causes of bottle mouth expansion and blowing out of gas: 1. The ambient temperature is too high. 2. The bottom solution for the cooling effect of the oven air flow: 1. Adjust the position of the cooling plate so that it can strengthen the thread of the preform. protection of. 2. Optimize the design structure of the cooling plate (4) Reasons for the blue bottom line: 1. Excessive blowing pressure 2. Insufficient pressure on the stretching rod Solutions: 1. Set the blowing time and speed 2. Check whether the stretching rod is blocked (5 ) Bottom damage reasons: 1. The temperature at the bottom of the preform is too low. 2. The position of the stretch rod is too high. Solutions: 1. Adjust the heating temperature at the bottom of the preform. 2. Adjust the position of the stretching rod reasonably. Cause of damage: The thread area suffers from unnecessary stretching, and the surrounding high temperature makes the temperature of the thread area of u200bu200bthe preform too high. Solutions: 1. Ensure that the adjustment of the conveying arm is accurate. 2. Accurate positioning of the preform, while reducing the heating temperature of the thread area, optimizing Structural design (7) Reasons for excessive drop of liquid level: After the pet container is filled, the solution drops, and the blowing temperature is too high, resulting in the formation of pearlescent phenomenon. Solution: Adjust the temperature of the heating furnace to avoid hanging heating or cold starting. (8) Reasons for the bursting of the bottle body: 1. Excessive temperature causes bursting or the bottle body is too thin 2. The blowing time is too short, resulting in excessive internal stress Solutions: 1. Adjust the temperature of the bottom of the bottle 2. Extend the delayed blowing time (9) The obvious reason for the clamping line: During the blowing process of the automatic bottle blowing machine, the gas cannot be discharged from the exhaust hole in time, and the thin layer of material constituting the bottle wall blocks the exhaust hole. Solutions: 1. Correctly adjust the mold gap 2 , High-pressure air valve to control airflow 3. Improve the design structure (10) Reasons for bottom wrinkles: if the external wrinkles are not enough, the pressure of the blow molding machine is not enough, and the stretching rod is too much to push the material down; the internal wrinkles generally overheat the head end of the preform or The solution to the delay of stretching pressure at the beginning: 1. Ensure that the timing of blowing bottle 1 on the mold is continuous and consistent. 2. The end of the preform should not be overheated. (11) Causes of hot bottle: The bottle is overheated, causing recrystallization inside or outside the preform, resulting in bottle bursting Solutions: 1. The stretching time is too long 2. Adjust the position of the cooling plate (12) The gram weight of the section is uneven (neck The part is too heavy) Reason: 1. The stretching rod is stretched down and up and gradually becomes cold, the material is very thin, and the cooling is accelerated. Solutions: 1. Adjust the hot spot position 2. Adjust the position of the cooling plate (13) The bottom eccentricity reason: 1. Conveying And alignment problem 2. The back door part is not concentric with the bottle. Solutions: 1. Adjust the preform mold transportation and alignment 2. The pressure setting of the stretching rod is too low. 3. The pressure of the blowing bottle 1 is too high and premature. 4. The stretching rod The cushions are not properly adjusted. (14) Pearlescent - the cause of foot hair: the root is the cold bottle. The direct result of stretching beyond the natural stretch limit is actually that the onlooker structure of the bottle is stretched and torn, and the formed tear points are reflected into visible pearlescent light. Solution: 1. Make sure the bottom of the bottle is in the center 2. Reduce the speed of the blowing machine 3. The stretching rod has been in contact with the preform for too long, and the blowing and air intake speed needs to be adjusted faster or earlier. (15) Reasons for out of tolerance bottom clearance: Exceeding the natural stretch limit Solutions: 1. Strengthen heat dissipation at the bottom of the bottle 2. Thicken the overall preform to reduce the bottom temperature. 3. Ensure the normal circulation of mold cooling water

Yosion Machinery, as well, confirms that consumers who want ethically produced goods do the work of looking for them.

Yosion Machinery builds value for our investors through the strength of our customers’ satisfaction and by consistently producing superior operating results.

The success of bottle blowing machine of campaigns largely rides on how you market your company to the crowd.

Overwhelming customers with too much information or the slew of benefits bottle blowing machine provides–even if they're all valid–is a surefire way to lose their attention.

bottle blowing machine are raising the stakes of social marketing, but they also ease the sales process by providing ways for pet bottle making machine manufacturers to effectively interact with customers.
