Problems solved by technology

The treated water contains a large amount of toluene, xylene, ketones and other organic volatile solvents and other chemical substances, which are very harmful, such as: polluting the air, consuming a large amount of petroleum energy, reducing the quality of finished shoes, and prone to waste products, etc.
[0003] At present, there are studies on the use of low temperature plasma technology to treat the surface of shoe materials. The outsole of shoes made of PEBA and Pa materials is treated to increase the firmness of the adhesion. This document does not provide a specific method of how to process the shoe material, nor does it involve the application of plasma surface activation technology and plasma-induced grafting technology.
It can be seen in domestic literature that plasma surface treatment technology is applied to other industries to improve the adhesive strength of other materials, such as: the article "Plasma surface treatment improves the surface of ultra-high molecular weight polyethylene fibers" in the Journal of Chongqing Institute of Architecture and Engineering No. Adhesive Performance", the article discloses the use of low-temperature plasma technology to treat the surface of polytetrafluoroethylene materials and study its adhesive properties, but none of them involve the treatment of shoe materials

Abstract

The invention discloses low-temperature plasma discharge processing equipment and a low-temperature plasma discharge processing method for the shoe material surface. The equipment comprises a machine frame, wherein the machine frame comprises a feeding section, a processing section and a discharging section which are arranged in sequence; a pair of stretchable feeding pushing rods are arranged at the front end of the feeding section; a vacuum box for low-temperature plasma discharge processing is arranged in the processing section; the vacuum box comprises a separable vacuum box body and a lower door plate; upper transmission lead rails are respectively arranged at two sides of the machine frame, and each transmission lead rail comprises an idler wheel lead rail at the feeding section and an idler wheel lead rail at the discharging section; the idler wheel lead rail at the feeding section and the idler wheel lead rail at the discharging section are respectively fixedly arranged on the machine frame through stretching cylinders; and a plurality of emptying supporting trays are arranged on the upper transmission lead rails. With the adoption of the processing equipment and processing method, high adhering performance of the shoe material can be ensured, the pollution is reduced, the harm to a worker is reduced, and the cost of production is greatly reduced.

Description

technical field [0001] The invention relates to the field of shoe material surface treatment, in particular to a shoe material treatment device, and more particularly, to a low-temperature plasma discharge treatment device and a treatment method for the shoe material surface. Background technique [0002] my country is a big country in the production and consumption of various types of shoes. According to incomplete statistics, the output of shoes is about 11 billion pairs, accounting for more than 60% of the world's output. At present, in order to ensure the strength of the adhesive during the shoemaking process, various treated waters are generally used to pre-treat shoe materials (including uppers and soles) before bonding. The treated water contains a large amount of volatile organic solvents such as toluene, xylene, ketones and other chemical substances, which are very harmful, such as: polluting the air, consuming a large amount of petroleum energy, reducing the qualit...
