Large-reeled constant-force roll-up device

Abstract

The invention discloses a large package constant force rolling-up device, which comprises a pair of frames, a pair of diving rollers arranged between the two frames, a rolling-up shaft arranged above the driving rollers and a power set driving the driving rollers to rotate, wherein one end of each driving roller is arranged at the extending-out end of a pressure sensor, while the other end of the pressure sensor is fixed on the frames; moreover, the pressure sensor is connected with the power set through a signal processor and an actuator; in addition, the rolling-up shaft is connected with the power set. The invention has the advantages that: with simple and practical structure, the large package constant force rolling-up device can maintain stable tension of fabric during coiling process and makes fabric roll even.

Description

Technical field [0001] The invention relates to a large-package constant-force winding device used for collecting cloth rolls on textile machinery equipment. Background technique [0002] The existing large package constant force winding device structure includes a pair of frames, a pair of transmission rollers arranged between the two frames, a winding shaft arranged above the transmission roller, and a power device for driving the rotation of the transmission roller. The power device described is composed of a transmission chain arranged at one end of two transmission rollers and a motor that drives the transmission chain. When the winding device is used, because there is no power on the winding shaft, the cloth collected on the winding shaft rotates passively with the two driving rollers, but as the diameter of the cloth roll on the winding shaft increases, the weight of the cloth roll on the winding shaft also increases. Continuously increase, so that the tension of the cloth...

AI Technical Summary

Problems solved by technology

When the winding device is in use, since there is no power on the winding shaft, the cloth collected on the winding shaft rotates passively with the two transmission rollers, but as the diameter of the cloth roll on the winding shaft increases, the weight of the cloth roll on the winding shaft also decreases. Continuously increasing, in this way, the tension of the cloth will change during winding, resulting in differences in the compactness of the cloth rolls. Usually, the cloth rolls close to the winding shaft are looser, while the cloth rolls close to the outer diameter of the winding shaft are denser. Therefore, it will cause uneven cloth rolls, which is not conducive to the subsequent processing.
