Coating machine capable of spraying on two sides of non-woven fabric and recovering dyes

Abstract

The invention discloses a coating machine capable of spraying on the two sides of a non-woven fabric and recovering dyes, and belongs to the technical field of coating machines. The coating machine includes a base, a cloth unwinding device and a cloth winding device. A cloth tensioning cleaning mechanism is arranged at the position, located on the front side of an assembly plate, of the left sideof the top of a supporting platform, a dye spraying mechanism is arranged at the position, located on the front side of the assembly plate, of the top center of the supporting platform, and a drying mechanism is arranged at the position, located on the front side of the assembly plate, of the right side of the top of the supporting platform. The coating machine is provided with the cloth tension cleaning mechanism, a U-shaped frame in the middle can be driven to be adjusted in lifting and lowering modes by driving a linear telescopic motor so as to adjust the tension of cloth, with the transmission of the cloth and through the affection of friction, remaining dust on both sides of the cloth is absorbed through a dust sticking film on the outer walls of tension rollers of the cloth tensioncleaning mechanism while the tension rollers rotate, so that the subsequent operations can be met, after cleaning is carried out, bumps on the surface of the cloth due to impurities do not exist, andthe production demands are met.

Description

technical field [0001] The invention relates to the technical field of coating machines, in particular to a coating machine that can spray on both sides of non-woven fabrics and can recycle dyes. Background technique [0002] The coating machine is mainly used for the surface coating process production of film, paper, etc. This machine is to coat the rolled substrate with a layer of glue, paint or ink with specific functions, and then wind it up after drying. [0003] Existing fabrics will use coating machines during production and processing, but the existing coating machines have the following defects when spraying fabrics: 1. Due to the unavoidable impurities on the surface of non-woven fabrics during the production process, there are no After treatment, the coating effect will be deteriorated, and even there will be bumps on the surface of the non-woven fabric, which will affect the yield of the product; 2. Double-sided spraying cannot be carried out at the same time, wh...

Problems solved by technology

[0003] Existing fabrics will use coating machines during production and processing, but the existing coating machines have the following defects when spraying fabrics: 1. Due to the unavoidable impurities on the surface of non-woven fabrics during the production process, there are no After treatment, the coating effect will be deteriorated, and even there will be bumps on the surface of the non-woven fabric, which will affect the yield of the product; 2. Double-sided spraying cannot be carried out at the same time, which greatly reduces the spraying efficiency of the non-woven fabric; 3. 2. After the non-woven fabric is sprayed, it is necessary to dry the non-woven fabric. Most of the existing drying equipment uses independent drying equipment. Therefore, after the non-woven fabric is sprayed, it needs to be manually transported to the drying equipment for drying. It reduces the work efficiency and increases the cost of use; 4. The existing coating machine cannot recycle the dye well, which further increases the cost of use
