Strip tension control device

Abstract

The invention provides a strip tension control device, and relates to the technical field of tension control. The strip tension control device comprises an outer shaft, an inner shaft, a first motor,a second motor, a first passing roller and a second passing roller; the inner shaft coaxially penetrates through the outer shaft; the inner shaft and the outer shaft can rotate separately and independently; the first motor is used for driving the outer shaft to rotate; the second motor is used for driving the inner shaft to rotate; the first passing roller is fixedly mounted on the outer shaft andis used for conveying a first strip; and the second passing roller is fixedly mounted at the part, penetrating out of the outer shaft, of the inner shaft and is used for conveying a second strip. According to the strip tension control device, the outer shaft can be driven by the first motor, the first passing roller can be driven by the outer shaft, the inner shaft can be driven by the second motor, the second passing roller can be driven by the inner shaft, and tension control on the first strip and the second strip is realized, so that the tension of the strips is kept consistent in the conveying process, and normal winding of the strips is facilitated.

Description

technical field [0001] The present application relates to the technical field of tension control, in particular, to a strip tension control device. Background technique [0002] Strip cutting and winding are integral steps in the production of tabs, and the strip needs to be tensioned for cutting or winding. When tensioning, it is necessary to control the tension of the strip. If the tension is too high, the strip may break, and if the tension is too small, the strip may curl. [0003] In the prior art, it is impossible to control the tension of the two strips at the same time, and it is difficult to ensure that the tension of the two strips remains consistent during the transfer process after the strips are cut or stripped. Contents of the invention [0004] The purpose of this application is to provide a strip tension control device, which can control the tension of two strips. [0005] The embodiment of the application is realized like this: [0006] Embodiments of t...

AI Technical Summary

Problems solved by technology

When tensioning, it is necessary to control the tension of the strip. Too much tension will easily cause the strip to break, and too small tension will easily cause the strip to curl.

[0003] In the existing technology, it is impossible to control the tension of the two strips at the same time, and it is difficult to ensure that the tension of the two strips remains consistent during the transfer process after the strips are cut or slitting.
