Yarn pressing device fast to assemble and disassemble

Abstract

The invention relates to a yarn pressing device fast to assemble and disassemble. The yarn pressing device comprises a yarn pressing pillar, a yarn pressing plate assembled on the periphery of the yarn pressing pillar in a sleeved mode, a cover assembled and fixed to the outer end of the yarn pressing pillar and provided with a third through hole and a clamping and pulling protruding block, a stud shaft sequentially penetrating through the cover and the yarn pressing pillar and jointed with a nut in a screwed mode, and a stop collar arranged at the joint between the yarn pressing pillar and the cover in a sleeved mode. The stop collar can prevent the yarn pressing plate of the yarn pressing device from disengaging from the yarn pressing pillar in the using process, when the yarn pressing plate needs to be maintained and detached from the yarn pressing pillar due to faults, other assemblies do not need to be detached any more, and the maintaining work of the yarn pressing device can be easily and rapidly conducted only by pulling out the stop collar.

Description

technical field [0001] The present invention relates to a quick assembly and disassembly of the yarn presser, especially the limit ring in the components of the yarn presser, which can prevent the yarn presser from being improperly detached from the yarn presser column during operation, but when the yarn presser must be disassembled for some reason When detaching the yarn pressing post, as long as the limit ring is removed and the stud shaft does not need to be turned out, the assembly and disassembly operation of the yarn pressing device can be easily and quickly achieved. Background technique [0002] see Figure 7 , Figure 8 , the existing yarn presser constituting unit A is set on the inner side of the extension plate B1 of the yarn entry seat B, and the yarn pressing unit A includes: a yarn pressing column A1 vertically fixed on the inner side of the extending plate B1, the yarn pressing column A1 has a threading groove A11. A set of yarn pressing plate A2 outside th...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the above-mentioned existing yarn presser constituting unit A is that when the first ring body A21 and the second ring body A22 are repaired and disassembled (or assembled), the bolt A4 must be completely turned out (or turned in) before proceeding, so Its maintenance (assembly) operation has the problem of consuming man-hours, which urgently needs to be improved by the relevant industry
