Semi-finished hook-and-loop fastener dyeing and drying device

Abstract

The invention discloses a semi-finished hook-and-loop fastener dyeing and drying device. The device comprises a dyeing box and a drying box; a heating plate is installed in the drying box; a purification mechanism is connected to the outer wall of the drying box; a right-angle plate is fixed to the end part of the dyeing box; a cavity is formed in the right-angle plate; a first gear is installed in the cavity; a reset mechanism is connected between the first gear and the cavity; a motor is fixed in the cavity; the driving end of the motor is fixedly connected with an incomplete gear meshed with the first gear; and guide rods are fixed to the inner walls of the two sides of the lower end of the cavity. Before a hook-and-loop fastener is dyed and dried, folding of the hook-and-loop fastener is eliminated through reciprocating movement of a smoothing roller, so that it is guaranteed that the hook-and-loop fastener makes full contact with dye liquor and hot air flow, and the dyeing and drying effects are guaranteed; and water vapor generated in the drying process is condensed and purified, so that the problem of pollution is avoided.

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