Principle of large plate drawing hot melt welding machine:

The large-scale hot-melt welding machine adopts the plate structure, and the heat of the heating plate is transferred to the welding surface of the upper and lower plastic heating parts by the electric heating method. Melt its surface, and then quickly withdraw the heating plate. After the upper and lower heating elements are heated, the melting surface is fused, solidified and integrated. The whole machine is in the form of frame, which is composed of three large plates: upper formwork, lower formwork and hot formwork, and is equipped with hot mold and upper and lower plastic cold mold. The action mode is pneumatic control. The metal hot plate is directly processed with the weldment to reach the melting point, the hot plate exits, and the pressure is applied on the two joint surfaces to finally achieve the welding result; It is mainly suitable for welding large plastic workpieces such as lamp, water tank, electric iron, balance ring of washing machine, car toilet, shower and so on. The utility model has the advantages of solving the problem of difficult welding of large arc lamp, beautiful and convenient welding.

Features of large plate drawing hot melt welding machine:

1. The large-scale plate drawing hot-melt machine adopts man-machine interface and PLC computer control system. The machine operates without error, and the operation is convenient and safe;

2. The large-scale hot-melt machine can easily solve the welding of large or irregular plastic workpieces;

3. The digital PID temperature control function of large plate drawing hot melt machine makes the welding temperature more stable and the welding effect better;

4. The large-scale plate drawing hot melt machine carries the hot mold with linear guide rail, with high precision, guaranteed quality and durability;

5. The movable die locking design of the large plate drawing hot melt machine uses the original imported cylinder, electrostatic spraying chassis and advanced hard chromium plating treatment to make the appearance of the product beautiful and reliable;

6. In terms of the control circuit design of the large-scale plate drawing hot melt machine, the programmable controller is adopted, and the feeding, hot melt, curing time, automatic and manual functions can be set in the man-machine interface, which is especially suitable for the mutual fusion of two rubber parts after heating.

7. The large-scale plate drawing hot-melt machine adopts oil pressure buffer damping system, with minimal noise, light machine and convenient handling and installation;

8. The die of large-scale plate drawing hot-melt machine is specially designed with special surface treatment, which is not easy to glue. The die is made of aluminum alloy or titanium alloy, with stable quality.

Application of large plate drawing hot melt welding machine:

The large-scale plate drawing hot-melt machine is suitable for the welding of complex workpieces such as PP, PE and PA; Such as car lights, water tanks, bumpers, car turn lights, electric irons, balance rings of washing machines, vacuum cleaners, flying targets, floating balls, instruments, auto parts, electrical appliances, containers and other plastic products. After welding, the welding effect of air tightness and water tightness can be achieved.
