Description

TECHNICAL FIELD

[0001] The present application relates to the field of textile machinery, and in particular to a self-adaptive tension control device for a carding machine. BACKGROUND

[0002] In the textile industry, the carding machine is a very critical equipment, and its main function is to finely card the opened cotton layer, remove impurities and short fibers therefrom, and make the cotton fibers reach a parallel and straight state, so as to provide high-quality raw materials for subsequent spinning processes. The performance of the carding machine directly affects the quality and production efficiency of the final yarn.

[0003] In the internal mechanical transmission system of the carding machine, belt transmission is a commonly used transmission mode. The belt transmission has been widely used in the transmission of multiple components of the carding machine due to its simple structure, stable transmission, vibration absorption and buffering, and the ability to transmit power between large shaft spacings and multiple shafts. For example, when driving the key components such as the cylinder, the licker-in roller, and the doffer roller, the belt transmission can effectively transmit power from the driving motor to each working component, ensuring the coordinated operation of each part of the carding machine.

[0004] However, in actual production applications, the carding machine adopts the belt transmission mode, and the problem of slipping frequently occurs, which is an important factor affecting the stable operation and production quality of the carding machine. The slipping phenomenon not only leads to a significant decrease in transmission efficiency, making the components unable to operate at the predetermined speed and torque, and further affecting the carding effect of the cotton fibers, but also accelerates the wear of the transmission belt, shortens its service life, and increases the maintenance cost and production downtime of the equipment. Specifically, when the transmission belt slips on the pulley, the conveying speed of the cotton fibers becomes unstable, and local over-carding or under-carding may occur, resulting in uneven cotton layer quality, affecting the smooth progress of the subsequent spinning process, and ultimately reducing the quality indicators such as the strength and evenness of the yarn.

[0005] To solve the above problems, the present application provides a self-adaptive tension control device for a carding machine. SUMMARY
