Description

Technical Field

[0001] This utility model relates to the field of carbon fiber cloth impregnation technology, and in particular to a carbon fiber cloth impregnation production apparatus. Background Technology

[0002] Carbon fiber cloth possesses excellent properties such as high strength and high modulus, but unimpregnated carbon fiber cloth is relatively fragile and easily worn. Through impregnation, resin can fill the gaps between the fibers of the carbon fiber cloth, forming a robust composite material structure. This significantly improves the strength, stiffness, durability, and protective properties of the carbon fiber cloth, enabling it to better meet the stringent requirements for high-performance materials in aerospace, automotive, and electronic equipment industries.

[0003] Traditional impregnation methods, such as immersing the entire carbon fiber cloth in a container, result in uneven impregnation thickness, affecting the quality of the carbon fiber cloth. Manual impregnation is inefficient, and variations in tension due to different operator techniques make it difficult to guarantee fiber orientation and performance uniformity, especially for large-tow carbon fibers, making it even more difficult to obtain products with stable performance. Therefore, it is necessary to solve the above-mentioned technical problems. Utility Model Content

The connecting rod passes through a fixing block, and the fixing block is fixed to the inner side of the glue storage tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the telescopic cylinder and the sliding block cooperate with each other to facilitate the downward movement of the pressure roller, which improves the efficiency of fully impregnating the carbon fiber cloth with glue, thereby realizing the function of preventing different tensions during impregnation of the carbon fiber cloth.

A baffle plate is fixed between the heating chambers 5, and a sliding groove 6 is opened between the baffle plates. The baffle plates and the sliding groove 6 facilitate the vertical movement of the vertical telescopic mechanism.

[0021] In this utility model, the vertical telescopic mechanism includes telescopic cylinders 4 installed vertically on both sides of the upper middle part of the glue storage tank 1. The telescopic ends of the telescopic cylinders 4 are all fixedly connected to the upper middle part of the sliding block 7.

[0022] Working principle: When using this utility model, glue is first added through the glue storage tank 1. Then, the glue in the glue storage tank 1 is heated through the heating chamber 5 and the heating tube 10. Then, the crank 16 at one end of the positioning block 17 is rotated through the motor 9 and the rotating shaft 18. Then, the slider 15 is moved in the sliding groove connecting rod 14 through the crank 16 and the slider 15. The connecting rod 12 moves horizontally in the fixed block 11, thereby driving the stirring plate 13 to stir the glue horizontally and prevent the glue from solidifying. Then, the carbon fiber cloth is introduced from the guide roller 3 at one end through the glue storage tank 1 and the guide block 2. Then, the sliding block 7 is slid vertically in the sliding groove 6 through the telescopic cylinder 4 and the sliding block 7. Then, the carbon fiber cloth is pressed down through the pressure roller 8 to prevent the carbon fiber cloth from having tension.
