Blow molding machine is a machine that blows thermoplastic plasticized PVC, PE, PP, PET, HIPS and other thermoplastic plastic coils into high-grade packaging boxes, frames and other products of various shapes. The operation procedure is also very simple. It only needs to turn on the heating switch to turn on the heating time 掣 circuit, adjust the heating time 掣 time button, and select the appropriate electric heating time of the electric wood mold heating piece according to the actual packaging condition.
The principle of blow molding machine: blow molding is also called thermoplastic molding. This molding process mainly uses the vacuum blowing force generated by the vacuum pump to soften the thermoplastic plastic such as PVC, PET, PETG, APTT, PP, PE, PS, etc. The sheet is blown into a vacuum cover, a blown tray, a bulb, and the like in various shapes. The main structure is composed of feeding, pulling, upper and lower electric heating furnace, lower brake, multi-function adjustable size, lower mold plate, upper mold, upper gate, knife gate, slicing, releasing and equipped with vacuum device; Pneumatic device is the main power source, and its pull-tab and feed piece adopt electric, speed reducer, time relay, intermediate relay, travel switch and other electrical components to form a fully automatic control system.
The requirements of the blow molding machine for the control system are to ensure easy operation, high precision of mechanical action and temperature control, short production time, and as much as possible to save mechanical power consumption under the same production conditions.
