A special desizing device for blue calico

Abstract

The present invention designs a special desizing device for blue calico. Through the coordinated use of the bracket, main motor, driving roller, driven roller and desizing tool, the traditional blue calico manual desizing is replaced by an industrial automation scheme. While ensuring the quality of blue printed cloth remains unchanged, the production efficiency is greatly improved. In the present invention, the top of the knife body is a spherical end face, which reduces the damage caused by the edges and corners to the blue calico cloth surface compared with the top of the blade, and the knife body and the horizontal plane are at a certain angle of inclination, which is suitable for blue printing. The softness of the cloth body can better fit the surface of the blue calico body to avoid gaps between the cutter and the blue calico body, resulting in incomplete desizing. The blade is inclined to the side of the blade body close to the bracket, so that the blade can be inserted into the surface slurry of the blue calico at a gentle angle during the desizing process, reducing damage to the surface of the blue calico without affecting the desizing efficiency.

Description

technical field [0001] The invention relates to the field of blue calico manufacturing, in particular to a special desizing device for blue calico. Background technique [0002] Blue calico, also known as indigo calico, is commonly known as medicine-spotted cloth, watering flower cloth, etc. It is a traditional handicraft printing and dyeing product of the Han nationality. It has a history of 1,300 years. Originally printed and dyed with indigo. The blue printed cloth is baked with lime and soybean flour synthetic mortar, and is made by multiple printing and dyeing processes such as cotton, hand-woven, engraving, and squeegeeing. [0003] Indigo calico is extracted from Polygonum indigo as dye (indigo). Spread the hollow pattern on the white cloth, use a squeegee to scrape the anti-dyeing agent into the gaps in the pattern and print it on the cloth surface. After drying, put it in For the dyeing vat, take out the vat after 20 minutes of cloth, oxidize it, and ventilate it...

AI Technical Summary

Problems solved by technology

In the traditional handicraft industry, this process is mainly done manually, which is time-consuming and labor-intensive, and the work efficiency is low, which affects the development of blue calico to a certain extent.
