A tension balance device for strip winding and its control system

Abstract

The invention discloses a tension balancing device for belt material winding. The device comprises a balancing roller, a first driving mechanism and a second driving mechanism, wherein the balancing roller comprises a roller body and a mandrel; the roller body is of an ellipsoid structure and is rotatably connected to the mandrel; the first driving mechanism is used for adjusting the amount of movement of the balancing roller in the horizontal direction; and the second driving mechanism is used for adjusting the horizontal height and / or the horizontal included angle of the balancing roller. Acontrol system of the tension balancing device for the belt material winding comprises the tension balancing device, a detecting device and a control device; the detecting device is used for detecting the ups and downs fluctuation condition of the belt surface in the width direction in real time; the control device is used for acquiring the detection data of the detecting device and controlling the first driving mechanism and the second driving mechanism to act based on the acquired detecting data so as to adjust the horizontal height, the horizontal included angle and the amount of horizontal movement of the roller body. With the adoption of the device, the belt can run in an uniform stress distribution state, and thus the problem of deviating in winding is avoided.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a tension balance device for coiling a strip and a control system thereof. Background technique [0002] During the rolling process of the strip-shaped material, due to the uneven thickness or surface density of the strip itself, the uneven surface of the roller during the rolling process, and the unstable tension may cause the strip to be unevenly rolled in the transverse direction, resulting in Some areas of the strip show wavy undulations. These undulations will cause the strip to pass through the roller. The rollers are in closer contact and receive greater friction. The difference in the force of different parts of the strip will cause the deviation of the running track of the strip, which will cause a spiral deviation during the subsequent winding process, which will affect the quality of the winding. In the battery field, the deviation during the winding process of th...

Problems solved by technology

The difference in the force of different parts of the strip will cause the deviation of the running track of the strip, which will cause a spiral deviation during the subsequent winding process, which will affect the quality of the winding. In the battery field, the deviation during the winding process of the pole piece will cause As a result, the negative electrode cannot cover the positive electrode, which seriously affects the production efficiency, and at the same time, the battery has a great safety hazard
