Hot wind pre-drying apparatus of continuous pigment dyeing pad dyer

Abstract

The invention relates to a hot-air preliminary drying device of a continuous pigment dyeing padding machine. The device comprises a box body, a textile conveying device, a hot air system and an air discharging system. The textile conveying device comprises an upper twitch roller group and a lower twitch roller group which is arranged below the upper twitch roller group. The device also comprises a drive mechanism which is arranged on a left plate of the box body and connected with each upper twitch roller. The hot air system comprises an upper air channel and a lower air channel which is arranged below the upper air channel. The upper twitch roller group and the lower twitch roller group are vertically arranged between the upper air channel and the lower air channel. The air discharging system comprises an exhaust duct which is arranged at the rear side inside the box body and protrudes upwards out of the top plate of the box body. An air inlet is formed on the part of the exhaust duct, which is arranged inside the box body. When in use, the device has better preliminary drying effect, and can further improve efficiency and preliminary drying quality after related electric control gears are added to the device.

Description

technical field [0001] The invention relates to a component of a fabric dyeing and finishing device. Background technique [0002] Continuous dyeing equipment is suitable for the dyeing process of a large number of fabrics, with high labor productivity. The continuous pad dyeing machine is generally composed of several parts such as a padding device, a drying device and a washing device. According to the composition of the unit machine, it can be applied to the dyeing of various dyes, such as reactive dyes, vat dyes, insoluble azo dyes, soluble vat dyes, phthalocyanine dyes, etc. [0003] The fabric paint pad dyeing process uses paint colorants and high-strength binders (non-aldehyde cross-linking agents) to make pad dyeing liquid, which is evenly penetrated and adsorbed on the cloth through padding, and then dried to make the dyeing liquid (paint and adhesive) cross-linking, fixed on the fabric, self-cross-linking and bonding at room temperature, it can be fixed on the fa...

Problems solved by technology

However, this device has no exhaust mechanism. On the one hand, the circulation of the air flow cannot be formed in the hot air dryer. On the other hand, when the fabric is dried with hot air, steam will be generated on the surface of the fabric. May drip onto the surface of the fabric causing damage to the fabric, causing spots on dyed fabrics
