Plastic extruder low-load protection system

Abstract

The invention discloses a plastic extruder low-load protection system. The plastic extruder low-load protection system comprises a feed hopper, a plastic extruder main body, a rotating extrusion screw, a base and a supporting mechanism which is arranged on the surface of the base; and a moving mechanism is arranged in the base and comprises a movable plate, sliding holes, casters, supporting columns, buffer springs, a fixed groove and air cylinders. When the plastic extruder low-load protection system needs to be moved, the movable plate slides downwards by turning on the air cylinders and thecasters are contacted with the ground, and then the base can be pushed to allow the casters to roll on the ground, so that short distance movement and transportation of the base on the ground are facilitated, the physical strength of workers is saved, the time of the workers is shortened, and the movement cost of the plastic extruder low-load protection system is lowered; when the base does not move, the base is contacted with the ground through supporting legs, so that the firmness of the base on the ground is improved, and the base is prevented from sliding on the ground; and when the casters roll on the ground, the damping effect of the casters is improved through the elastic buffering of the buffer springs, and the service lives of the casters are prolonged.

Description

technical field [0001] The invention belongs to the technical field of low-load protection systems for extruders, in particular to low-load protection systems for extruders. Background technique [0002] The extruder is an important plastic machine. The production and manufacture of most plastic products can be realized by extrusion molding. The extruder motor is an important part of the extruder and the prime mover of the extruder. It provides The large thrust required by the screw of the extruder, the foaming agent, foam particles and other raw materials are extruded through the twin-screw extruder. cause casualties. [0003] Existing extruders use support legs to increase firmness when in use. Due to the large size and heavy weight of the extruder, it needs the cooperation of a crane and many people to move when moving on the ground. It is inconvenient and time-consuming to move in a short distance. It is laborious and increases the cost of using the extruder, so we pro...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an extruder low-load protection system to solve the above-mentioned background technology. The existing extruder uses support legs to increase the firmness during use. Because the extruder is large in size and heavy in weight, it cannot move on the ground. Sometimes it needs a crane and the cooperation of many people to move, which is inconvenient when moving in a short distance, time-consuming and labor-intensive, and increases the cost of the extruder.
