A hook and loop semi-finished product dyeing and drying device

Abstract

The invention discloses a hook and loop semi-finished product dyeing and drying device, comprising a dyeing box and a drying box, a heating plate is installed in the drying box, and a purification mechanism is connected to the outer wall of the drying box; the dyeing box The end of the box is fixed with a right-angle plate, and a cavity is opened inside the right-angle plate, a gear one is installed in the cavity, a reset mechanism is connected between the gear one and the cavity, and a motor is fixed in the cavity. The driving end of the motor is fixedly connected with an incomplete gear that meshes with gear one, and guide rods are fixed on the inner walls of both sides of the lower end of the cavity. The present invention eliminates the folding of the Velcro through the reciprocating movement of the smoothing roller before the Velcro is dyed and dried, ensures the full contact of the Velcro with the dye solution and the hot air, ensures the effect of dyeing and drying, and greatly improves the drying process. The water vapor generated in the system is condensed and purified to avoid the problem of pollution.

Description

technical field [0001] The invention relates to the field of Velcro processing technology, in particular to a dyeing and drying device for Velcro semi-finished products. Background technique [0002] Dyeing and drying is an important step in the production process of hook and loop fasteners. [0003] After searching, the Chinese patent document CN213038015U discloses a kind of dyeing and drying device for hook and loop semi-finished products, including a device body, and two vertical partitions are arranged in the device body, and the two vertical partitions divide the inner cavity of the device body into Pretreatment room, dyeing room, drying room, one side of the pretreatment room is equipped with a feed inlet, the pretreatment room is equipped with a suction plate on the upper surface and lower surface of the hook and loop, and the suction plate is connected with a negative pressure pipeline. In the dyeing room, there are rolling printing and dyeing devices on the upper ...

AI Technical Summary

Problems solved by technology

[0006] 1. The flatness of the fabric cannot be guaranteed, and the contact with the dye will be insufficient when the fabric is folded, which will affect the dyeing effect;

[0007] If the water vapor in the drying process is not discharged in time, it will cause secondary wetting of the fabric. If it is directly discharged, it will cause pollution due to water vapor or chemical substances in the condensed water
