Automatic tension control device of non-woven fabric dividing and cutting machine

Abstract

The invention provides an automatic tension control device of a non-woven fabric dividing and cutting machine and relates to the technical field of the dividing and cutting machines. The automatic tension control device is used for achieving automatic control of tension of the non-woven fabric dividing and cutting machine. The automatic tension control device comprises supports, a supporting roller, shaft sleeves, rod-shaped parts, a counter weight part, a rotatable tension roller and an air cylinder. The supports are used for supporting other parts. The two ends of the supporting roller are movably arranged on the supports through bearing components. The shaft sleeves capable of freely rotating are arranged at the two ends of the supporting roller in a sleeved mode. The rod-shaped parts extend forwards and backwards from the shaft sleeves respectively. The stationary counter weight part and the tension roller are connected to the free ends of the rod-shaped parts on the two sides of the shaft sleeves respectively. The two ends of the air cylinder driving the rod-shaped parts to rotate around the supporting roller are movably connected with the supports and one rod-shaped part respectively. An input shaft of an encoder is connected with a chain wheel in a chain transmission mode, and the chain wheel is fixed on one shaft sleeve. The encoder is in signal connection with a motor through a wire and the motor is used for driving a paying-off roller to rotate. The automatic tension control device achieves the automatic control of tension of the non-woven fabric dividing and cutting machine, and is accurate in tension adjustment and high in automation degree, and the dividing and cutting width of the non-woven fabric dividing and cutting machine for leftover materials can be freely adjusted.

Description

technical field [0001] The invention relates to the technical field of slitting machines, in particular to a control device capable of automatically adjusting tension in the slitting process of non-woven fabrics. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Advantages such as low cost and recyclability. When the non-woven fabric slitting machine is used in the slitting process of non-woven fabrics, the wide-width non-woven fabric rolls are cut into narrow-width rolls suitable for various production needs, and the cut edge parts become waste. During the working process of the slitter, the position of the cutter on the cutter shaft is fixed. In order to save fibers and reduce the trimming rate, it is necessary to adjust the tension of the rewinding and unwinding by controlling the speed of the rewinding and unwinding. Due to the ...
