Device for cutting gasket of compressor of refrigerator

Abstract

The invention discloses a device for cutting a gasket of a compressor of a refrigerator. The device comprises a rack, a cutting knife and a cutting base and further comprises a power device, wherein the cutting base is positioned at one side of the cutting knife; the power device comprises a lever, a lever base and a cam; the lever is hinged on the lever base; a strip-shaped hole is formed in the upper end part of the lever; the cutting knife is rotatably connected with a rolling shaft; a third spring is connected between the lever and the rack; the lower end part of the lever abuts against the cam; a knife head of the cutting knife is in sliding connection into a pressure plate; a through hole is formed in the pressure plate; a first spring is connected between the pressure plate and the cutting knife; a groove is formed in the cutting base; a buffer base is connected in the groove; a second spring is connected between the buffer base and the bottom wall of the groove; the bottom of the buffer base is connected with a limiting block; the limiting block is positioned between the pressure plate and the buffer base; a fixed plate is arranged between the limiting block and the buffer base in an abutting-against manner; and the fixed plate is fixedly arranged in the groove. The cutting knife cuts back and forth, so that the number of operation steps is decreased; and the pressure plate and the limiting block are arranged, so that labor intensity is reduced, and the manufacturing cost is also reduced.

Description

technical field [0001] The invention relates to a cutting device, in particular to a gasket cutting device for a refrigerator compressor. Background technique [0002] The rubber sealing ring is referred to as gasket for short. The gasket is usually an annular ring with good elasticity. It is often used for sealing liquid or gas. Many gaskets are used on the compressor of the refrigerator to stop the gas in the compressor. The leakage of refrigerant and special oil requires the following steps in the process of making refrigerator compressor gaskets: 1. Recycling of old materials, cutting and crushing the recovered waste materials, so that the rubber materials are evenly distributed into small particles, Then, the small granular rubber is transported from the transport device to the conveyor, and then transported to the next process by the conveyor; 2. Melting, put the rubber broken into uniform small particles into the melting furnace, and the melting furnace will heat up. ...

AI Technical Summary

Problems solved by technology

[0003] For the above steps, the cutting step is more important, and the cutting efficiency directly affects the yield of the apron. In order to solve the above problems, there is a cutting device in the prior art, which includes a cutting knife, a cylinder, a cutting seat, a cylinder output rod and a cutting The tops of the knives are connected, and the cutting seat is set directly below the cutting knife; during specific operations, the operator puts the rubber hose on the cutting seat, and then uses the cylinder to control the downward movement of the cutting knife and cuts the rubber hose; The knife is reset, because the cut part of the rubber hose becomes a gasket, so when the cutting knife descends again, the cutting knife cannot cut the shortened rubber hose, and the operator needs to adjust the position of the rubber hose to the position that needs to be cut

[0004] Although the efficiency of the above cutting devices has been improved, there are still certain problems: 1. Using the cylinder to control the reciprocating movement of the cutting knife requires the operator to control each direction change, which not only increases the operating steps, but also increases the operator's work. Labor intensity; 2. Every time the rubber hose is cut, the operator needs to control the position of the rubber hose, which also increases the operation steps and increases the labor intensity of the personnel. Moreover, the thickness of each gasket cannot be guaranteed, which increases the amount of defective products obtained. , higher manufacturing cost
