Active pay-off device for knitting machine

Abstract

The invention relates to an active pay-off device for a knitting machine and belongs to the technical field of wire and cable production devices. The knitting machine comprises a knitting machine body, and the active pay-off device comprises a base, a front roll shaft, a rear roll shaft, a pair of front bearing blocks and a pair of rear bearing blocks. The base is installed on a floor in front of the knitting machine body, the pair of front bearing blocks is installed on the base and is close to one side of the knitting machine body, front rolling bearings are installed in the pair of front bearing blocks, the front roll shaft is installed on the pair of front rolling bearings, the pair of rear bearing blocks is installed on the base and is far away from one side of the knitting machine body, rear rolling bearings are installed in the pair of rear bearing blocks, and the rear roll shaft is installed on the pair of rear rolling bearings. The active pay-off device has the advantages that active pay-off is facilitated, constant pay-off tension is guaranteed, and thinning or deformation of a semi-finished product cable is avoided; the active pay-off device is simple in structure, saves energy and is environmentally friendly and low in production cost; installing and dismantling operation of a pay-off reel is simple, operation time is saved, and labor intensity is reduced; and the active pay-off device is suitable for pay-off reels of any size.

Description

technical field [0001] The invention belongs to the technical field of wire and cable production equipment, and in particular relates to an active wire releasing device for a braiding machine. Background technique [0002] The function of the wire and cable shielding sleeve braiding machine is to weave a metal mesh sleeve that is usually bare copper wire or tinned steel wire outside the semi-finished wire and cable. At present, the production of most metal mesh sleeves starts from paying off to taking up. Therefore, the pay-off device is an indispensable part of the cable production equipment. The convenience of loading and unloading the pay-off reel directly affects the efficiency of production. , and whether the pay-off device is durable is related to the maintenance cost of the equipment and whether continuous normal production can be guaranteed. The structure of the pay-off device varies according to the supporting equipment. The pay-off device on the traditional knitt...

AI Technical Summary

Problems solved by technology

The disadvantages of the above-mentioned structure are: firstly, a pay-off reel with a large size cannot be installed on the support shaft, so the scope of use is narrow; secondly, the position where the pay-off reel is installed is fixed, and in the actual production process, the pay-off reel cannot be installed. The outer diameter of the reel will often change, which will cause the tension of the semi-finished cable on the pay-off reel to change, and this change in tension will affect the uniformity and compactness of the wire arrangement on the pay-off reel; third, pay-off After the end, the support shaft needs to be removed when replacing the pay-off reel, which is not only labor-intensive and time-consuming, but also very inefficient, and the labor intensity of the workers is also high
