Center and friction winding device

Abstract

The invention discloses a center and friction winding device, which comprises a fixed mount, wherein the fixed mount is provided with a friction winding device and a center winding device; the friction winding device is arranged on a bottom board of the fixed mount and comprises a friction roller and a first driving device which drives the friction roller to rotate; two sides of the fixed mount are provided with first guide rails which are provided with a sliding plate respectively; the sliding plates are provided with a central shaft and a second driving device which drives the central shaftto rotate; and the top end of the fixed mount is provided with a constant-speed lifting device which is used for controlling the lifting of the sliding plates. The center and friction winding device has the advantages that the winding diameter for winding is large, and edge turning down and center loosing phenomena cannot be generated.

Description

technical field [0001] The invention relates to a winding device, in particular to a center and friction winding device for winding gray cloth. Background technique [0002] At present, there are mainly two types of winding devices, one is a friction winding device, which mainly uses a motor to drive the friction roller to rotate, and the cloth is wound on the shaft through the friction between the cloth surface and the friction roller. , the cloth roll wound by this kind of winding device is loose inside and tight outside, the cloth roll is not neat enough, and the phenomenon of core pulling in the middle and edge collapse will occur during frictional winding. Therefore, it is difficult to roll the cloth roll very large. It is difficult to meet the customer's requirements for the number of rolls. The other is the central winding device, which uses the central shaft to drive the cloth roll to rotate, and rolls the cloth on the central shaft. The cloth roll wound by this wind...

[0002] At present, there are mainly two types of winding devices, one is a friction winding device, which mainly uses a motor to drive the friction roller to rotate, and the cloth is wound on the shaft through the friction between the cloth surface and the friction roller. , the cloth roll wound by this kind of winding device is loose inside and tight outside, the cloth roll is not neat enough, and the phenomenon of core pulling in the middle and edge collapse will occur during frictional winding. Therefore, it is difficult to roll the cloth roll very large. It is difficult to meet the customer's requirements for the number of rolls. The other is the central winding device, which uses the central shaft to drive the cloth roll to rotate, and rolls the cloth on the central shaft. The cloth roll wound by this winding device is tight on the inside and loose on the outside. In addition, the central shaft has to bear the entire weight of the fabric, which is easy to bend and deform the central shaft, which affects its service life. Although the central winding device does not suffer from core pulling and edge collapse during winding, due to the limited force of the central bearing, Therefore, it is also difficult to roll the cloth very large
