Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a glass fiber base cloth coating device. Background Art

[0002] Glass fiber base cloth is a fabric made of glass fiber through a textile process (mainly weaving or knitting). This fabric maintains the high strength, low elongation, corrosion resistance, high temperature resistance and other characteristics of glass fiber, and is one of the important reinforcing materials for manufacturing composite materials. It is widely used in many fields of industrial production and daily life, such as aerospace, automobile manufacturing, shipbuilding, wind turbine blades, building materials and sports equipment. When glass fiber base cloth is used as a reinforcing material, it is usually cured together with the resin material (such as epoxy resin, polyester resin, etc.) to which it is coated to form a hard and lightweight composite material component. Its grid structure can effectively disperse external forces and improve the stability and load-bearing capacity of the overall structure. Simply put, glass fiber base cloth is a high-performance industrial fabric that provides an indispensable reinforcement solution for modern engineering and manufacturing industries.

[0003] The glass fiber fabric coating process, also known as the preparation of glass fiber reinforced composite prepregs, involves immersing the glass fiber fabric in a leaching solution to form a prepreg, an intermediate material in the manufacture of composite products. However, existing glass fiber fabric coating equipment directly exposes the fabric to the leaching solution during the coating process. This short immersion time results in poor coating results, and incomplete contact between the fabric and the leaching solution leads to reduced coating efficiency and reduced work efficiency. Summary of the Invention

[0004] The purpose of the utility model is to provide a glass fiber base cloth coating device with high working efficiency in view of the above problems existing in the prior art.

[0005] The purpose of this utility model can be achieved through the following technical solutions:

[0006] The roller is connected with the roller to move the rollers, and the rollers are connected with the rollers to move the rollers, and the rollers are connected with the rollers to move the rollers, and the rollers are connected with the rollers to move the rollers.

[0007] The present invention creatively sets up a coating box, a feed roller, a tensioning roller, a driving member, a coating brush, a stirring member, and an extruding member. The order of the cloth path is: feed roller, tensioning roller, tensioning roller, feed roller. The feed roller supports the cloth and the tensioning roller tensions the cloth. The leachate in the coating box must be immersed above the two tensioning rollers. The coating brush is driven to reciprocate by the driving member. During the movement, the coating brush penetrates into the leachate and rests against the upper surface of the cloth between the two tensioning rollers, repeatedly applying the leachate to the cloth evenly, making the contact between the cloth and the leachate more thorough. The bristles of the coating brush are compatible with the leachate, and because the bristles have a certain elasticity, they ensure uniform pressure and help the leachate penetrate the cloth.

[0008] During the coating process, the stirring element can stir the leaching liquid to prevent the leaching liquid from settling and improve the coating effect.

[0009] The extruder can perform the final compression on the cloth to prevent the cloth from shifting and further squeeze out the excess leachate.

[0018] The rotation of the screw can drive the movable plate to move left and right, thereby driving the coating brush to move left and right. During the movement, the coating brush can evenly apply the extraction liquid on the cloth, making the contact between the cloth and the extraction liquid more thorough.

[0019] In the above-mentioned glass fiber base fabric coating device, the extrusion part includes a fixed plate, which is fixedly connected between the front and rear side walls of the inner cavity of the coating box.
