Thread-knotting-preventing thread releasing device for knitting machine

Abstract

The invention discloses a thread-knotting-preventing thread releasing device for a knitting machine, and belongs to the field of thread releasing devices. The thread releasing device comprises a base,and a stand column is fixedly welded to the upper end face of the base. According to the thread-knotting-preventing thread releasing device for the knitting machine, a check ring moves leftwards, a small ball is driven to be separated from clamping of a fixed shaft ball groove, and the check ring is conveniently and rapidly disassembled and assembled; a rolling wheel is in sliding connection withthe upper end of the right side of a connecting frame, the moving direction of a sewing thread is conveniently guided, and the circumstance that the sewing thread shakes and is separated from conveying of the rolling wheel, and mechanical faults are caused is prevented; through the design of an inclined face, the sewing thread can slide towards the middle of the rolling wheel, and conveying of the sewing thread is facilitated; through the cooperative design of a first rolling wheel, a second rolling wheel and a third rolling wheel, the sewing thread can be in a tightened state, and the circumstance that the sewing thread is loosened, and later production is affected is prevented; a clamping block is fastened and clamped to a clamping groove, a screw is tightened clockwise, a supporting frame can be fixed, and rotation of the supporting frame is prevented; and through the design of a guide cylinder, the moving direction of the sewing thread can be guided, and the circumstance that thesewing thread shakes substantially, and production is affected is prevented.

Description

technical field [0001] The invention relates to the field of pay-off devices, in particular to a pay-off device for knitting machines used to prevent thread knotting. Background technique [0002] The types of raw materials applicable to the knitting machine are: nylon multifilament (thread), polypropylene filament (thread), polypropylene, polyester, nylon, PP, low elastic, high elastic, cotton yarn (thread), pearl light, leather, mixed, etc. Knitting machines can be divided into sweater knitting machines, glove knitting machines, steel wire knitting machines, wire mesh knitting machines, straw rope knitting machines, elastic band knitting machines, plastic mesh bag knitting machines, etc. [0003] Existing knitting machines use anti-knotting thread unwinding devices and sewing coil disassembly and assembly. It is necessary to remove the nut at the end of the fixed shaft and use tools to replace the sewing coil, which is inconvenient for quick replacement. At the same time, ...

AI Technical Summary

Problems solved by technology

[0003] Existing knitting machines use anti-knotting thread unwinding devices and sewing coil disassembly and assembly. It is necessary to remove the nut at the end of the fixed shaft and use tools to replace the sewing coil, which is inconvenient for quick replacement. At the same time, the sewing thread is entangled in a large area On the outer surface of the sewing coil, the sewing thread shakes from side to side during the conveying process and is separated from the conveying roller, causing mechanical failure. In addition, the sewing coil is slidably sleeved on the outer surface of the fixed shaft, and the sewing thread will loosen during the conveying process, affecting post production
