A tension device for coiler of a needle-carding machine

Abstract

The invention provides a gilling machine coiler tensioning device. The gilling machine coiler tensioning device is mounted inside a coiler; the coiler comprises a driving wheel, a coiler can and a canframe; the gilling machine coiler tensioning device comprises a first tensioning wheel, which is tightly attached to a flat belt and provided in a penetrated mode with a first connecting shaft in theaxial direction, the upper end of the first connecting shaft is provided with threads, and the first tensioning wheel can rotate horizontally relative to the first connecting shaft; the upper end ofthe can frame is provided with a first bar-shaped hole, and the upper end of the first connecting shaft extends out of the first bar-shaped hole and is fixed through a first nut; the side end of the can frame is provided with a first threaded hole, inside which a first bolt is arranged in a penetrating mode, and one end of the first bolt abuts against the first connecting shaft. The gilling machine coiler tensioning device can solves the problem that existing gilling machine coiler tensioning devices are unsteady in tension and a first tensioning wheel is prone to loosening to result in largetension fluctuation, accidental traction and influence on yarn evenness of subsequent machines.

Description

technical field [0001] The invention relates to the technical field of tension devices, in particular to a tension device for a coiler of a needle carding machine. Background technique [0002] When the FD series needle carding machine actually produces short fiber products such as cashmere and yak cashmere, due to the nearly 90-degree change in the forward direction when the cashmere sliver enters the coiler during the transfer process, the resistance increases greatly. The tension draft in the front area is slightly larger, and the velvet has accidental drafting, and the 13cm mechanical wave amplitude is obvious, which affects the evenness; the tension draft is slightly smaller, and the velvet foaming is serious at the entrance of the coiler, and the tension fluctuates greatly, which also causes accidental drafting. Stretching will affect the dry quality of the lower machine, especially when spinning short fibers below 40mm, the reaction is more obvious, and it is difficul...

Problems solved by technology

[0003] Aiming at the defects of the prior art, the present invention provides a tension device for a coiler of a needle carding machine, which can solve the problem that the existing tension device of the coiler of a needle carding machine is unstable in tension, and the tensioning wheel is easy to loosen, resulting in large fluctuations in tension, resulting in Accidental drafting, which affects the dry quality of the off-machine sliver
