A kind of coating equipment

Abstract

The invention belongs to the technology for coating surfaces of objects through liquid or other fluid, and particularly relates to coating equipment. The coating equipment comprises a rack, a smoothening part, a bonding part, a cleaning part and a transmission mechanism, the rack is sequentially provided with a feeding unit, a bonding unit, a drying unit and a discharging unit, the smoothening part comprises a steel ball, a compressed spring and a cam for intermittently hitting the steel ball, the bonding part comprises an upper roller used for grinding base cloth and a lower roller used for supporting transfer paper, the cleaning part comprises a rotary barrel rotationally connected with the rack, the rotary barrel is rotationally provided with a cleaning piece used for cleaning the surface of the upper roller in a connected manner, and the transmission mechanism comprises a motor, a upper roller gear, a lower roller gear, a rotary barrel gear, a driving bevel gear and a driven bevelgear. According to the scheme, folding of the base cloth in the coating process can be effectively prevented.

Description

technical field [0001] The invention belongs to a technology for coating liquid or other fluids on the surface of objects, and in particular relates to a coating device. Background technique [0002] Coating, also known as coating, refers to the finishing and processing technology of uniformly coating one or more layers of polymer compounds on the surface of the fabric, and forming one or more layers of thin films on the surface of the fabric through bonding. Its purpose is to improve the feel, appearance and style of the fabric, and add many new functions to the fabric, such as windproof, waterproof, moisture-permeable, down-proof, flame-retardant, shading and other functions. [0003] The traditional coating method is mostly direct coating, that is, the coating agent is diluted with solvent or water according to the required concentration, and the necessary medicament and colorant are added to make a coating slurry, which is evenly coated on the base cloth with a spreader ...

AI Technical Summary

Problems solved by technology

[0005] However, there are certain problems in the existing transfer film-forming method: when the calender roller is rolling the base fabric and the transfer paper, the base fabric is prone to wrinkle, and one of the reasons for this phenomenon is that the calender roller The surface of the roller is not smooth enough, especially when dealing with some easy-to-depilate fabrics, the lint on the fabric is easy to stick to the surface of the calender roller when it is crushed by the calender roller, so that the accumulation increases, and the calender roller becomes larger. Surface roughness, wrinkling phenomenon is more obvious
