Coating device used for special coating glass fiber cloth preparation

Abstract

A coating device used for special coating glass fiber cloth preparation comprises bottom frames, a shell, an exhaust pipe, column feet, a conveying roller, a transmission motor, a conveyor belt, a paint filling device, a spraying tool and a blade coating tool. The bottom frames are symmetrically arranged. The shell is arranged on the top faces of the bottom frames. Each column foot is arranged onthe lower surface of the bottom frame on the corresponding side. The conveying roller is arranged between the bottom frames on the two sides. The conveyor belt is arranged outside the conveying rollerin a wrapping manner. The paint filling device is arranged on one side of the bottom frames. The spraying tool is arranged above the bottom frames. The blade coating tool is arranged above the conveyor belt. The paint filling device is flexible to use and can clean the inner portion of a liquid storage cavity; and the device is stable in system operation, uniform in blade coating and high in coating efficiency.

Description

technical field [0001] The invention relates to the field of glass fiber cloth preparation, in particular to a coating device for preparing special coated glass fiber cloth. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other national economy fields. Glass fiber cloth made of glass fiber material usually refers to glass fiber grid cloth. The strength of the grid cloth is mainly in the warp and weft direction of the fabric. For occasions that require high warp or weft strength, it can also be woven into a unidirectional Cloth, it can arrange more rovings in the warp or weft ...

AI Technical Summary

Problems solved by technology

There are following defects in the prior art: (1) when the coating equipment in the prior art is coated, the paint flows out through the storage tank in the pre-storage and coating machine, and flows into the spraying device for spraying

The storage tank and the coating equipment are of an integrated structure. After long-term use, the inner wall of the storage tank cannot be cleaned, causing the paint to easily accumulate in the storage tank and form agglomerates, which cannot be cleaned and removed from the discharge tank; at the same time, the same machine is required When the coating equipment switches between different coating raw materials for coating, the storage tank cannot be cleaned, which will easily lead to contamination between raw materials and affect the coating effect

(2) When the paint is sprayed, the paint needs to drip slowly from the coating nozzle, and the coating speed is slow, resulting in low efficiency of the coating equipment, and the glass fiber needs to be conveyed through the conveyor belt during the spraying of the coating nozzle. It is difficult to match the speed and transmission speed, which may easily lead to uneven coating

(3) When the paint is applied, the coating equipment does not have a mechanism for fixing and compressing the glass fiber cloth, and the glass fiber cloth is prone to wrinkles when it is applied under force, resulting in uneven application process, affecting product performance, and even affecting the continuous operation of the equipment (4) The scraper of the smearing equipment is usually in direct contact with the glass fiber cloth. It is pressed on the surface of the glass fiber cloth by external force, and the scraper is moved in translation. When the force is uneven or the surface of the glass fiber cloth is uneven , easily lead to tearing of glass fiber cloth, affecting product performance
