Description

Technical Field

[0001] This invention relates to the field of Teflon fabric impregnation technology, specifically to an impregnation mechanism for manufacturing Teflon fabric. Background Technology

[0002] Teflon cloth, scientifically known as polytetrafluoroethylene coated fiberglass cloth, also called Teflon high-temperature resistant coated cloth, is made by impregnating high-performance fiberglass cloth with a suspended polytetrafluoroethylene emulsion. It is a high-performance, multi-purpose composite material product. Due to its excellent properties, it is widely used in aerospace, papermaking, food, environmental protection, printing and dyeing, clothing, chemical, glass, pharmaceutical, electronics, insulation, construction, grinding wheel cutting, and machinery. In the manufacturing process, the cloth needs to be immersed in a glue tank containing the emulsion. However, in the current production process, the direct immersion method is inefficient. During processing, the emulsion slowly penetrates into the cloth, and after the latex penetrates the cloth surface, the surface latex also intercepts the latex in the tank. In addition, the latex near the cloth is absorbed, while the latex far away is almost unaffected, resulting in uneven distribution of latex in the tank. Therefore, it is necessary to provide power for the process of latex immersion into the cloth and to keep the latex in the tank flowing continuously to improve the uniformity of the latex. For this purpose, the present invention provides an impregnation mechanism for manufacturing Teflon cloth. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The working mode of this invention can ensure that the Teflon cloth is fully impregnated with resin. The power component controls the shaft, the shaft controls the continuous conveying of the closed-loop rubber belt, all the power rods on the closed-loop rubber belt move, and the power rods actuate the punching device one by one. Each punching device completes one deformation and reset. During the process, fluid that vertically impacts the raw material cloth is generated, which accelerates the impregnation of the cloth and ensures that the emulsion completely penetrates into the raw material cloth, thereby improving the product quality of Teflon high-temperature cloth.

[0014] 2. This invention utilizes the cooperation of a power rod, a punching device, and a closed-loop rubber belt. The closed-loop rubber belt drives the power rod, which triggers each punching device one by one, thus avoiding the large torsional force on the raw material cloth caused by all punching devices working simultaneously. All the fabric lifting slides cooperate to support the raw material cloth, and only a few of the fabric lifting slides move in a circular motion each time. In this way, the raw material cloth is stably laid flat on multiple fabric lifting slides under the clamping of four clamps. Attached Figure Description

[0035] Every part of the raw material fabric 2 has the opportunity to come into contact with the emulsion. The forward and reverse rotation of the fluid fan 35 causes the emulsion to flow vertically and impact the raw material fabric 2. The resulting fluid impacts the raw material fabric 2 upwards. When the fluid fan 35 reverses, the fluid flows downwards. The fluid suction causes the emulsion above the raw material fabric 2 to form a fluid that impacts the raw material fabric 2 downwards. This reciprocating fluid impact causes the fabric to be quickly impregnated with the emulsion. The specific process is as follows: the top of the short shaft 8 is externally connected to the existing drive mechanism. The rotation of the short shaft 8 drives the first gear 9, which then drives the external gear ring 44 through the first shaft 23. The rotation of the external gear ring 44 controls the closed-loop rubber belt 17 to convey the material, thereby driving all the power rods 1. 5. When the power rod 15 encounters the material-thrusting device 16, the power rod 15 supports the second spring plate 37, controls the rack 38 to move, and the rack 38 drives the outer gear ring 44 to rotate. Then, the inner control column 42 is controlled to rotate through the cross plate 45. When the rack 38 moves to the maximum distance, the power rod 15 breaks through the obstruction of the second spring plate 37, and the outer gear ring 44 reverses under the reset control of the spring spring 43. When the power rod 15 passes the material-thrusting device 16, the inner control column 42 rotates forward half a turn and then reverses half a turn to reset. The inner control column 42, the fluid fan 35 and the fabric lifting slide column 32 rotate synchronously. The fabric lifting slide column 32 moves during the process of supporting the raw material cloth 2.
