High-frequency resonance melt extruder for processing plastic products

Abstract

The invention relates to the field of plastic product processing, in particular to a high-frequency resonance melt extruder for processing plastic products. The high-frequency resonance melt extrudercomprises a machine body, an extruding mechanism, a preheating device and a feed mechanism, wherein the extruding mechanism, the preheating device and the feed mechanism are arranged in the machine body, the extruding mechanism is located in an extruding cavity formed in the middle of the machine body, the preheating device is located on the left side of the machine, and the feed mechanism is located on the right upper side of the machine body. According to the high-frequency resonance melt extruder for processing the plastic products, the tail ends of two screws are fixed by a shaft, so thatthe screws do not rub or deviate during rotation, and the problems of mechanical wear and vibration are solved; the preheating device is additionally arranged, so that the degree of purity and the molten state of materials at the front stage before the machine is started are guaranteed; and a speed limiting device is additionally arranged, so that the inlet and outlet speed of the materials is guaranteed, and the materials are prevented from overflowing.

Description

technical field [0001] The invention relates to the field of plastic product processing, in particular to a high-frequency resonance melting extruder for plastic product processing. Background technique [0002] The screw of the traditional extruder is easy to rub against the barrel wall, which leads to serious wear and tear of the machine. The traditional extruder has no preheating device, which leads to impurities or impurity in the material that comes out at the beginning, resulting in serious deformation of the plastic product. The traditional extruder Without a speed limiting device, it is difficult to control the speed of material in and out, resulting in material overflow and waste. Therefore, it is intentional to invent a preheating extruder with stable speed control to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a high-frequency resonance melting extruder for processing plastic products, which can ...

AI Technical Summary

Problems solved by technology

[0002] The screw of the traditional extruder tends to rub against the barrel wall, causing serious wear and tear on the machine. The traditional extruder has no preheating device, which leads to impurities or impurity in the material that comes out at the beginning, resulting in serious deformation of the plastic product. The traditional extruder There is no speed limiting device, it is difficult to control the speed of material in and out, resulting in material overflow and waste, so it is intentional to invent an extruder that can be preheated and speed controlled to solve the above problems
