Description

Technical Field

[0001] The present invention belongs to the technical field of hair scraping devices, and particularly relates to a hair scraping mechanism and device. Background Art

[0002] During the dyeing process of fabrics, a large amount of wool yarns and silk scraps will fall off from the fabric surface, which has a great impact on subsequent fabric processing. Therefore, it is necessary to filter the above-mentioned wool yarns, etc., to facilitate collection and recycling. The traditional hair scraper uses a stainless steel thin sheet spring as the hair scraping blade, which is installed on the main shaft and rotates integrally with the main shaft. Its working principle is: after the hair scraping blade is installed on the main shaft, the outer diameter of the blade will have an interference of about 10 mm with the inner diameter of the filter barrel. After the main shaft and the hair scraping knife assembly are assembled with the filter barrel, due to the elastic deformation of the hair scraping blade, its elastic deformation force will make the hair scraping knife tightly press against the inner wall of the filter barrel, and the blade will scrape off the fine hairs attached to the filter barrel by means of this pressing force.

[0003] However, the yarns falling off from the fabric surface have high toughness and long thread ends. When most of the yarns start to accumulate, due to the elastic deformation of the scraper, the hair scraping knife cannot scrape off the accumulated yarns with its own rigidity and directly slides over the surface of the thread ends, resulting in new elastic deformation. This phenomenon is called skipping the knife. This causes a vicious cycle between the accumulated yarn thread ends and the new elastic deformation generated by the hair scraping knife, resulting in blockage of the filter barrel and the equipment cannot operate normally. Moreover, due to the long-term continuous operation of the machine, the hair scraping knife constantly encounters external forces (the resistance of broken hairs) and generates elastic deformation. Under the action of the above cyclic load for a long time, it is very easy to cause fatigue fracture. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a hair scraping mechanism and device, which can realize the adjustment of the pressing force at the cutting edge of the hair scraping knife, avoid the occurrence of skipping the knife phenomenon, ensure the normal operation of the equipment, and reduce the production cost.

[0005] The technical solution adopted by the present invention to solve its technical problems is:

[0006] A hair scraping mechanism includes a scraper arm, one end of the scraper arm is hinged on a main rotating shaft, and a hair scraping blade is arranged at the other end of the scraper arm; wherein,

[0007] It further includes a guide post, one end of the guide post is hinged on the scraper arm, and the other end of the guide post is slidably arranged on the main rotating shaft; an adjustable member is arranged on the guide post, and a spring is sleeved on the guide post between the adjustable member and the main rotating shaft.

[0008] Preferably, a scraper shaft is provided corresponding to the scraper arm. One end of the scraper shaft is arranged on the main rotating shaft and fixed by a fastener, and the other end of the scraper shaft is hinged to the scraper arm.

[0009] Preferably, a mounting plate is provided corresponding to the guide post. One end of the mounting plate is fixedly arranged on the main rotating shaft, and the other end of the mounting plate is provided with a through hole for the guide post to slide through, and the spring is arranged between the mounting plate and the adjusting member.

[0010] Preferably, an anti - detachment portion is provided at the end of the guide post protruding outside the mounting plate, and the diameter - width value of the anti - detachment portion is greater than the diameter - width value of the through hole.

[0011] Preferably, the guide post is a bolt, and the adjusting member is a nut threadedly connected to the bolt.

[0012] Preferably, at least two nuts are provided.

[0013] A hair scraping device includes a main rotating shaft and also includes a hair scraping mechanism as described above.

[0014] Preferably, a plurality of the hair scraping mechanisms are arranged at intervals along the length direction of the main rotating shaft, and two adjacent hair scraping mechanisms arranged along the length direction of the main rotating shaft are spaced at an angle.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] In this solution, a guide post is ingeniously provided corresponding to the scraper arm, and an adjusting member and a spring are arranged on the guide post. By the adjustable property of the spring, the pressure of the scraping blade pressing on the inner surface of the barrel is adjusted. While effectively increasing the pressing force at the cutting edge of the scraping blade, the rigidity of the scraping blade itself is maintained, thus effectively solving the problem of tool jumping and the resulting blade tearing in the traditional technology. In this solution, the elastic force received by the scraping blade is greater, and it is also easier to cut the yarn, thus effectively solving the problem of easy blockage on the inner wall of the barrel of the traditional hair scraper and ensuring the normal operation of the equipment.
