Manufacturing method of hot melt machine convenient for manual operation

1. This utility model relates to the field of hot melt machines, in particular to a hot melt machine that is convenient for manual operation.

Background technique:

2. The hot melt machine uses an electric heating method to transfer the heat of the heating plate to the welding surface of the upper and lower plastic heating elements to melt the surface, and then quickly withdraw the heating plate. After the upper and lower heating elements are heated, the melting surfaces are fused and solidified. Integrated instrument. The whole machine is in the form of a frame, composed of three plates: an upper template, a lower template, and a hot template. It is equipped with a hot mold and an upper and lower plastic cold mold. The action mode is pneumatic control and manual mode. It is mainly suitable for welding plastic parts such as household appliances, car lights, and automobile melters. The hot melt machine can set the heating power and mold size according to the size of different plastic parts to realize the welding of a variety of plastic workpieces, with simple operation and convenient use. The heating plate is composed of two upper and lower parts, which are heated by electric heating tubes.

3. However, in the process of heating the plastic parts in the traditional hot melt machine, the air cylinder is generally used to drive the heating plate to move close to the plastic part, so that the heating plate melts the surface of the plastic part, but the electric heating plate and the plastic part The distance between the heating plate and the plastic part determines the melting effect. If the distance between the heating plate and the plastic part is too large, it will take a long time to melt and the melting effect is not good. If the distance between the heating plate and the plastic part is too small, It may cause damage to other parts of the plastic part. The traditional method of driving the heating plate with an air cylinder is not suitable for high-precision machining operations.
