Description

technical field [0001] The invention relates to a sanding machine, in particular to a pre-wet drying sanding machine, which belongs to the technical field of textile machinery. Background technique [0002] The pre-wet drying and sanding machine in the prior art includes a frame, a sanding area, and a cloth feeding and cloth discharging mechanism. The sanding area is provided with multiple sets of sanding rollers, a dust suction cover is arranged below the sanding rollers, and a dust cover is arranged above the sanding rollers. There is a spraying device; there are rolling cars in the front and back of the sanding area, and the sides of each group of sanding rollers are equipped with supporting rollers and pressure rollers. Adjusting the height of the supporting rollers can control the contact angle between the cloth and the sanding rollers, thereby controlling the wool height , The pressure roller is driven by the pressure roller cylinder. When the pressure roller is presse...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the weft insertion from one side during the weaving process, the left, middle and right tensions of the gray cloth itself are unequal. The direct sanding of such gray cloth will cause inconsistent sanding effects in the side and the middle, which will obviously appear in the subsequent dyeing process. ; In addition, the wettability of chemical fiber fabrics and water is not good, and the cloth is not soaked while watering while sanding, which affects the sanding effect

[0005] 2. During the operation, the gray cloth in the cloth bucket is shifted or artificially turned when the cloth falls, so it cannot be very neat, especially after turning, it will cause a large skew or the edge of the cloth is folded, and the cloth often enters before it is flattened. work area, will cause fabric defects
