A winding device capable of realizing fixed-point cutting on the winding core

Abstract

The invention provides a rolling device capable of realizing fixed-point cutting on a roll core. The rolling device comprises a substrate and a rolling frame, wherein the rolling frame comprises a main shaft and a plurality of rolling shafts; the rolling shafts are evenly distributed around the circumference of the main shaft; two ends of each rolling shaft are respectively fixedly connected with the main shaft by two side plates; the rolling shafts rotate relative to the side plates; two ends of the main shaft are rotatably installed on the substrate; each rolling shaft is axially provided with a sticking strip. The rolling device also comprises a first power mechanism and a second power mechanism, wherein the first power mechanism drives the main shaft to rotate, and the second power mechanism drives the rolling shafts to rotate. The rolling device also comprises a first control mechanism and a second control mechanism, wherein the first control mechanism is used for controlling the rolling frame to stop rotating when each rolling shaft on the rolling frame rotates to a working station on which a friction roll is positioned; the second control mechanism is used for controlling the rolling shafts to stop rotating when the sticking strips on the rolling shafts rotate to a film joint position on the friction roll.

Description

technical field [0001] The invention relates to the technical field of design of a winding device, in particular to a winding device capable of realizing fixed-point cutting on a winding core. Background technique [0002] Film winders are an essential part of the film production process, and there are various types of film winders. At present, in the film winding process, there are usually multiple winding stations on one winding frame, that is, corresponding to multiple winding shafts; the winding device in the prior art, when changing rolls at multiple stations, different stations When the rewinding shaft is connected to the film, it cannot be connected to the designated position on the surface of the die (that is, the location where the adhesive strip is set); this will easily lead to unevenness of the rewinding joint, which will cause wrinkles on the film after rewinding, which will affect the quality of the product. , and there will be a lot of waste generated.
