Description

Technical Field

[0001] The utility model relates to the technical field of shoe processing, in particular to a plastic welding machine for shoe processing. Background Art

[0002] The plastic welding machine transmits ultrasonic energy to the welding area through the upper weldment. Since the acoustic resistance of the welding area, i.e. the interface between the two welds, is large, local high temperature will be generated. Due to the poor thermal conductivity of plastic, it cannot be dissipated in time and gathers in the welding area, causing the contact surface of the two plastics to melt rapidly. After a certain pressure is applied, it is fused into one. When the ultrasonic wave stops working, the pressure is allowed to continue for a few seconds to solidify and form, thus forming a strong molecular chain to achieve the purpose of welding. The welding strength can be close to the strength of the raw materials. In the process of shoe processing, since the soles of some shoes need to be glued with a layer of plastic air cushion or a plastic pad of special material, people will turn the bottom of the shoe upwards, and then place the plastic air cushion or plastic pad on top of it, and then use the corresponding plastic welding machine to weld the plastic air cushion or plastic pad to the bottom of the shoe, thereby completing some shoe processing techniques.

[0003] The existing plastic welding machine for shoe processing usually has a poor pressing effect on the shoe and cannot take away the heat from the surface of the shoe after welding. Therefore, we propose a plastic welding machine for shoe processing. Utility Model Content
