Non-indentation variable-tension rolling mechanism

Abstract

The invention discloses a non-indentation variable-tension rolling mechanism which comprises a spreading roller, a lifting device, a photoelectric distance measuring device, a rolling vehicle, a variable-tension power transmission box and a PLC. The lifting device comprises lifting steel wires on the two sides, steel wire length adjusting bolts, a large winding chain wheel, a small winding chain wheel, a winding motor, a lifting arm supporting pipe, lifting arms on the two sides, a hinge iron support, a winding sleeve and a lifting winding shaft. The photoelectric distance measuring device comprises a photoelectric distance measuring sensor, and the photoelectric distance measuring sensor is installed on the lifting arm supporting pipe through an adjusting plate and a support. The rolling vehicle comprises a vehicle frame and a rolling roller, and fabric is wound on the rolling roller. The lifting winding shaft is driven by the winding chain wheels to rotate, the steel wires are pulled, the lifting arm is pulled upwards by a certain distance, automatic rolling of the press-roller-free fabric is achieved, it is guaranteed that the fabric is smooth, and free of wrinkles and indentations after being processed and stored; and meanwhile, the labor intensity of workers is relieved, and the labor safety is guaranteed.

Description

technical field [0001] The invention relates to textile finishing equipment, in particular to a rolling mechanism with no indentation and variable tension. Background technique [0002] At present, textile fabrics need to be stored after fluffing, ironing, and setting. The storage process must be flat and wrinkle-free. Due to the soft nature of textile fabrics, the traditional way of releasing fabrics is to directly drop the fabrics into the cloth container for storage. It is difficult to ensure the smoothness of the fabrics, and it is prone to wrinkles, which affects the quality. There are generally three existing common solutions: one is the manual operation of the saddle-type cloth drop method, the other is to use active pressure rollers for rolling, and the third is constant tension rolling. All three methods have the following disadvantages. The manually operated saddle-type cloth dropping method requires high physical strength of the workers, and the labor intensity i...

Problems solved by technology

The three methods all have the following disadvantages. The manual saddle-type cloth dropping method requires high physical strength and labor intensity, and it cannot completely guarantee no wrinkles.

Using the active pressure roller for rolling is to press an active guide roller with a certain pressure on the rolling roller to roll the fabric. First, the safety is poor, and it is easy to press people, causing safety accidents; second, because the active guide roller has a certain The pressure is pressed on the curling roller, especially the wool feeling of the raised fabric will be "squeezed to death"

Rolling with constant tension will cause wrinkles on the inner side of the cloth roll, because the fabric has a certain degree of elasticity, after rolling with constant tension, the fabric will rebound to a certain extent, and the amount of rebound on the inner and outer sides of the cloth roll is the same, which will cause the inner cloth roll to wrinkle , produce indentation

Therefore, the above three methods are not ideal
