Working principle of PET bottle blowing machine
PET bottle blowing machine is a bottle blowing machine equipment for blowing preforms made of PET (full name: polyethylene terephthalate) material. It is mainly used for carbonated beverage bottles, mineral water bottles, cosmetic bottles, and oil bottles. , Space cups, medicine bottles and other hollow plastic containers blowing bottles. PET bottle blowing machine passes preform-transferring-heating-clamping-stretching-blowing into bottles.
1. Automatic loading hoist
The preforms are manually poured into the loading hopper. The automatic loading elevator detects whether there are preforms in the loading track of the elevator through the induction monitoring system, and then starts automatic loading. During the loading process, the detection and transmission process is restarted. During the process, the preforms on the entire transmission track are already full, and the excess preforms are automatically returned to the hopper to ensure the advancement of the preform installation sequence.
2. The clamping and grabbing automatically flips the billet
The gripper passed the inspection, and it was found that the preform was automatically taken by the preform by the automatic claw, and the preform was turned over to the transmission chain
3. Transmission system
The transfer system is mainly to transfer the preform from the upper blank to the mold clamping. The transmission system is the hub belt that connects each link in series. The Tengyue bottle blowing machine adopts the invention patented technology, double-point and double-drive technology, which optimizes the bottle-blowing machine transmission system, guarantees the chain transmission, and increases the service life of the chain.
4. Heating control system
The heating control system determines the quality of the bottle blowing machine. Too high or too low temperature will cause the bottle to appear shapeless and white. The traditional heating system temperature is controlled at 40 degrees Celsius, which is greatly affected by the external temperature. The Tengyue bottle blowing machine adopts a 120 degrees Celsius constant temperature heating control system, and the external temperature is small. The temperature of each infrared light tube can be independently controlled, using two rows of tubes Heating at the same time, the spacing can be adjusted, and the rotary preform heating control system ensures that each part of the preform is evenly heated.
5. Mold clamping and blowing system
The conveying chain transfers the heated preform to the clamping device, and the stretching cylinder stretches the preform, and blows the preform into a bottle through pre-blowing and high-pressure blowing.
