Dehairing mechanism and device

Abstract

The invention belongs to the field of dehairing equipment, and aims to provide a dehairing mechanism and device. The dehairing mechanism mainly comprises a scraper arm; one end of the scraper arm is hinged to a main rotating shaft, and the other end of the scraper arm is provided with a scraper blade; the dehairing mechanism further comprises a guide column, one end of which is hinged to the scraper arm and the other end of which is arranged on the main rotating shaft in a relatively sliding mode. An adjusting piece with the adjustable position is arranged on the guide column, and a spring isarranged at the position, between the adjusting piece and the main rotating shaft, of the guide column in a sleeving mode. According to the invention, the pressing force at the cutting edge of the dehairing knife can be adjusted, the knife jumping phenomenon is avoided, normal operation of the equipment is ensured, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of shaving equipment, and in particular relates to a shaving mechanism and device. Background technique [0002] Since a large amount of wool and silk scraps will fall off the surface of the fabric during the dyeing process of the fabric, which will have a great impact on the subsequent fabric processing, it is necessary to filter the above-mentioned wool to make it easy to collect and recycle. The traditional hair scraper adopts a stainless steel sheet spring as the razor blade, which is installed on the main shaft and rotates as a whole with the main shaft. Its working principle is: after the shaving knife is installed on the main shaft, the outer diameter of the blade will be about 10mm more than the inner diameter of the filter barrel, and after the main shaft and shaving knife assembly are assembled with the filter barrel, due to the elastic deformation of the shaving blade, its elasticity The deformin...

Problems solved by technology

[0003] However, due to the high toughness and long thread ends of the yarns that fall off from the surface of the cloth, when most of the yarns start to accumulate, the scraper cannot scrape off the accumulated yarns with its own rigidity due to the elastic deformation of the scraper and directly removes the accumulated yarns from the thread ends. The surface slides over to produce a new elastic deformation, which is called jumping knife

The accumulated yarn ends and the new elastic deformation produced by the razor will have a vicious circle with each other, causing the filter barrel to be blocked and the equipment to fail to operate normally

Moreover, due to the long-term continuous operation of the machine, the shaving blade is constantly subjected to external forces (resistance of broken hair) to produce elastic deformation, and under the action of the above-mentioned cyclic load for a long time, it is easy to cause fatigue fracture
