Large-roll cloth rolling and unrolling machine

Abstract

The invention discloses a large-roll cloth rolling and unrolling machine which comprises a rack, a matt surface roller, a mirror surface roller, a fabric drum, a guiding roller, a tightening roller, amovable roller and a traction roller, wherein the matt surface roller and the mirror surface roller are mounted on the rack in parallel side by side; the fabric drum is erected and mounted on the matt surface roller and the mirror surface roller; the fabric drum and the matt surface roller are in parallel; the two sides of the lower part of the fabric drum are in contact with the matt surface roller and the mirror surface roller; fabric is rolled on the fabric drum; from the end of the fabric drum, the fabric sequentially passes through the mirror surface roller, the guiding roller, the tightening roller, the movable roller and the traction roller; and fixing seats are arranged at the two ends of the fabric drum to position and fix the fabric drum. The large-roll cloth rolling and unrolling machine is reasonable in structure, simple to operate, convenient to use and driven through force of friction, can automatically adjust the tension, is high in rolling and unrolling quality and stability, can be adapted to rolling of fabric with different specifications, and is wide in range of application, and high in flexibility and using effect.

Description

technical field [0001] The invention relates to the field of textile equipment, in particular to a large roll cloth winding and unwinding machine. Background technique [0002] The unwinding and unwinding machine is the unwinding or rewinding part of the fabric processing production line. It is mainly used to mechanically unwind the rolled fabric during unwinding, and it is mainly used to mechanically wind the fabric into rolls during winding. Winding and unwinding machines are widely used in processing production lines such as textile machines and printing machines, and the designs are diversified according to actual process requirements. [0003] In the existing winding and unwinding machines, it is difficult to control the tension of the coil during the winding or unwinding process, which often leads to changes in the tightness of the coil during winding, or changes in the tension during unwinding, which directly affects the tension of the coil. Especially during the win...

Problems solved by technology

[0003] In the existing winding and unwinding machines, it is difficult to control the tension of the coil during the winding or unwinding process, which often leads to changes in the tightness of the coil during winding, or changes in the tension during unwinding, which directly affects the tension of the coil. Especially during the winding process, it will further cause the surface diameter of the coil to be unequal, and there is a risk that the coil will collapse due to insufficient coiling

At the same time, during the winding and unwinding process, the fabric reel used to wrap the fabric is prone to jumping, especially during the unwinding process, the two sides of the fabric reel will experience uneven force, and the fabric is prone to deflection
