Component of polyester abrading machine

Abstract

The invention relates to an assembly used in a polyester grinder. The assembly consists of a chromium-plated wearable inlet part, a locknut for locking the inlet part and three polytetrafluoroethylene gaskets. The assembly is characterized by increasing the inner diameter of a lapping liquid inlet on a backwall plate from 40mm to 70mm, arranging the chromium-plated wearable inlet part, the three polytetrafluoroethylene gaskets and the locknut at the inlet, being capable of disassembling the part and the locknut after disassembling a connection tube of the lapping liquid inlet of the grinder, and being capable of disassembling and replacing the chromium-plated wearable inlet part (the length is 30mm) without disassembling all abrasive disks. The side surface at which the chromium-plated wearable inlet part contacts the lapping liquid and the inner surface thereof are plated with chromium, the thickness of the chromium layer is 1mm, the hardness of the chromium-plated layer is HV800, and the part is a consumable part, and is replaced every half a year when being substantially worn out, which can cause the grinder to take a new look after repair. The assembly has the advantages of simple and time-saving operation, less expense and less production cost.

Description

technical field [0001] The invention relates to a part of a grinding machine, specifically a grinding fluid inlet of a polyester grinding machine that can be disassembled and replaced without affecting the service life and use effect of the imported grinding machine. components. Background technique [0002] At present, the titanium dioxide (which acts as a matting effect, so it is also called a matting agent) grinder used in the production of polyester filament semi-dull fibers that are sold on the market and used in various factories, in the design of the structure of the entrance of the grinding liquid, due to When long-term production is not considered, the matting agent suspension containing 50% titanium dioxide will cause very large wear on the inlet, and generally wear through the rear wall of the grinder in one year. [0003] Moreover, since about 1 μm of titanium dioxide has already entered the gap between the grinding disc and the drive shaft of the grinding machi...

Problems solved by technology

Therefore, due to the suspension of the matting agent at the entrance of the grinding liquid of the original grinding machine, it is necessary to replace all the grinding discs and the entire rear wall after the annual wear-out of the rear wall, so that the grinder can be repaired, resulting in a lot of waste
