XG-A-2-3 high-efficiency program-controlled plastic pneumatic thermoforming machine, using the latest plastic sheet forming process technology, is an integrated design of machine, electricity and gas, using microcomputer and industrial control programmable PLC control, the entire system HMI (human-machine interface). Square tunnel-type imported radiation heater, both concave and convex molds can be formed, laser blade punching, its process flow: heating, forming, punching, stacking counting and other main multi-station production lines.

At the same time, the production line can run synchronously and simultaneously, using the current foreign and domestic forming process technology, reducing labor, preventing secondary pollution, saving materials, improving product quality and product qualification rate, doubling production efficiency, convenient operation, good reliability, strong functionality, high degree of automation, used for sheet thermoforming and product automatic punching integrated automatic production line.

Suitable for the forming of plastic sheets such as PLA, PS, ABS, PP, PVC, APET, PET, GAG, BOPS, etc. Processing products with high transparency, high stretch, shallow stretch, round, square, irregular, biaxial stretch, flanging, etc. Produce various plastic products such as fruit boxes, plates, electronic trays, bowls, cup lids, industrial packaging, food and drug packaging, cosmetics packaging and other packaging.

Supply sheet → convey sheet → first stage heating → second stage heating → third stage heating → → molding cooling → cutting → decomposition stacking → waste self-winding system

Note: There are three stations in total, operation scheme: manual/automatic integrated switching, manual is convenient for sampling and control parameter setting.

A. Equipment composition

The molding equipment consists of the main structure frame, positive and negative pressure molding system, temperature control system, vacuum system, heating system, gas control system, electrical and PLC control system, punching system, product decomposition stacking and edge material automatic winding system.

B. The main body of the equipment

It is made of square tube and channel steel and other steel structure profiles spliced ​​and welded, used for assembly heating, mold table molding, mold table punching and auxiliary devices. The overall steel structure is guided by , and all the parts involved fully comply with the process foundations of material quality selection, blank production method, machining, heat treatment, parts assembly, machine operation, machine maintenance, etc., to ensure that the movable device for transmitting and transforming motion and force has sufficient strength and rigidity. All metal surfaces are treated with anti-rust and the bottom layer is sprayed with anti-rust paint; general parts and standard parts are used in the structure to facilitate later maintenance and replacement of all parts.

C. Die table structure

The lower servo motor cam crank arm connecting rod is driven by a hard-toothed reducer, and the upper servo motor cam crank arm connecting rod is driven by a hard-toothed reducer.

D. Electrical and PLC control system/safety facilities

◇ The electrical control system adopts PLC integrated module control, with industrial touch display as HMI (human-machine interface), and adopts Chinese interface. The machine has button operation and setting and modification of all process parameters, making the equipment easy to operate and maintain.

◇ The whole machine works in manual/automatic mode, and all setting functions are operated on the touch display; when the operator places the material, the machine starts automatically to complete the entire molding process until the material in the silo is processed and produced; manual operation is mainly used for mold change or sample control.

◇ The system sets multiple protection measures, and each action that may collide with each other is equipped with interlocking and closed-loop control protection.

◇ The safety door protection seal design adopts manual buckle opening and manual locking. A safety grating is installed in the protection door to improve the safety factor of the equipment and ensure the safety of personnel and property.

◇ The power distribution cabinet contains a protection circuit, including overcurrent, overvoltage, undervoltage, short circuit and overload protection. The heating element has a fuse protection. For safety issues that may cause harm to the system or workpiece, there are warning signs or notes. 10% of the space is reserved in the control box for future changes, and the electric cabinet is installed with a filter and a protective cooling fan.

◇ All immovable cables and wires outside the power box are hidden in the cable trough for easy opening and repair. If this is not possible, use a hose to fix it.

◇ Multiple “emergency stop” buttons are installed in the front, middle and rear of the equipment. “Emergency stop” forces the power supply of the equipment to be cut off so that no dangerous situation occurs during “emergency stop”。
