Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a high-efficiency cooling device for a plastic extruder. Background Art

[0002] A plastic extruder is a device used to manufacture plastic products. It forms plastic products of various shapes and sizes by forcing heated plastic raw materials through a die. The working principle of the extruder is to use the pressure and heat generated by the rotation of the screw to melt the solid plastic raw materials into a liquid state, and then push it into the mold, where it cools and solidifies to form the final product. The main components of the extruder include the hopper, screw, heating element, mold, and cooling system. According to production needs, the extruder can be used in conjunction with different molds and auxiliary equipment to produce various plastic products such as pipes, profiles, films, wire insulation, etc.

[0003] When a plastic extruder produces a plastic model, it will cut the model one by one. However, since the plastic has a certain viscosity when it is just produced, it will stick to the cutter during cutting and cause wire drawing, which will cause the plastic model to deform, affecting the use of the model, wasting plastic resources, and requiring the model to be reprocessed. In addition, after the plastic extruder extrudes the plastic to produce a plastic model, the plastic cools down slowly and has a low cooling efficiency, which reduces the overall plastic model production efficiency.
