Description

Technical Field

[0001] The present invention belongs to the technical field of dipping machines, and particularly relates to a dipping machine with a tensioning function for the production of Teflon cloth. Background Art

[0002] In recent years, due to its excellent high-temperature resistance, chemical stability, low friction coefficient, non-stickiness and other characteristics, Teflon cloth has been widely used in many fields such as electronics, machinery, and food processing. The production process of Teflon cloth usually involves multiple key links, among which the dipping treatment is an important step to endow it with specific properties. The dipping treatment can enhance the strength, wear resistance, corrosion resistance and other properties of Teflon cloth, making the product better meet the requirements of different application scenarios.

[0003] When the existing dipping machines are performing dipping processing, for example, the Chinese invention patent with the publication number CN112452646B discloses a dipping machine, which includes a machine body. A glue spraying side frame is fixedly connected to the left side surface of the machine body. A reciprocating glue spraying machine is arranged on the upper part of the glue spraying side frame, and a conveying device is arranged inside the glue spraying side frame; a third spiral lifter is arranged on the upper surface of the machine body and on the left side, and a feeding pressure roller is arranged at the output end of the third spiral lifter. An auxiliary pressure roller is arranged inside the machine body and on the left side. The latex and silica gel are fully mixed by the reciprocating glue spraying machine, and then reciprocating glue spraying is carried out. Then, driven by the extrusion of the feeding pressure roller and the auxiliary pressure roller, the latex and silica gel can fully enter, so that the processed finished product can be exposed to the sun and boiled in water, and at the same time, the service life is longer. There is no need to provide a vacuum environment. The amount of glue contained in the fiber layer after processing is more. After dipping, the excess glue is extruded twice to reduce the waste of glue, and finally the bonding effect of the finished product is better.

[0004] When the existing dipping machines are performing dipping processing, for example, the Chinese invention patent with the publication number CN110449319A discloses a hanger dipping machine, which includes a hanger, a chain conveying mechanism, a heating oven, a low-temperature solidification oven and a dipping area; the chain conveying mechanism includes a chain and a motor, and the motor drives the chain to rotate. The chain passes through the heating oven, the low-temperature solidification oven and the dipping area; the hanger is fixed on the chain during use and moves along with the movement of the chain. It has the technical effect of improving the working efficiency of the dipping machine and reducing the labor force of workers.

[0005] However, when the existing dipping machine is dipping, the edges of the fabric may have a tighter weaving pattern or more thread accumulations, making it more difficult for the glue solution to penetrate, resulting in relatively less dipping amount at the edges and excessive or too small tension. When the tension is too large or too small, the fabric edges will be tightened, affecting penetration, or there may be slack and wrinkles, causing the glue solution to accumulate in these areas, which will affect the penetration speed and uniformity of the glue solution. At the same time, some dipping machines only perform a single heating operation on the dipped fabric. After the Teflon fabric is dipped, it needs to be dried and cured. During single heating, since the temperature is constant throughout the process, the fluidity change of the glue solution at different times is relatively small. It may cause the glue solution to start curing before it is fully leveled at the initial stage of heating, resulting in an uneven surface of the coating and local thickness unevenness.

When the tension needs to be increased, start the electric push rod 19 to push the connecting pipe 25 upward to move, so that the two connecting rods 16 push the moving roller 14 to slide in the arc-shaped chute 18, so that the moving roller 14 moves upward in the square plate 10, and the spring 17 is retracted under force, so that the Teflon cloth is tensioned. When the tension needs to be reduced, similarly start the spring 17 to move downward in the reverse direction, and the moving plate 15 can move up and down bidirectionally. One end of the cloth is pulled out from the feeding roller 12, wound around the top end of the limiting roller 13 along the bottom end of the moving roller 14, and then wound around the bottom end of the rotating roller 21 in the dipping assembly to dip the cloth. When the cloth is moved into the dipping tank 20, the cloth is dipped through the rotating roller 21. Excessive glue flows through the circular holes 31 into the collection box 24, passes through the filter screen 30 along the inclined surface of the collection box 24, and the mist spray head 32 sends the glue in the collection box 24 back to the glue storage tank 2 for reuse. After the Teflon cloth is dipped, it is sent to the middle of the two scraping rollers 27. The second motor 29 drives one group of gears 28 and the scraping roller 27 to rotate clockwise, so that the other group of gears 28 and the scraping roller 27 rotate counterclockwise to scrape the upper and lower ends of the passing Teflon cloth. The scraped glue flows to the dipping tank 20 through the inclined guide plate 26. After the Teflon cloth is scraped, the two sensors 23 identify the edge of the cloth. When the sensor 23 on the right side identifies that the thickness does not meet the requirements, the water pump 34 is started to convey the glue in the glue storage tank 2 into the conveying pipe 22, so that it is sprayed out through the atomizing nozzle 32 to supplement the spraying of the cloth. At the same time, if the sensor 23 on the left side fails to identify uneven thickness, the solenoid valve 33 is opened so that the conveying pipe 22 can flow to the atomizing nozzle 32 on one side for identifying and spraying the other edge of the cloth; After the Teflon cloth is sprayed, it is transported to the preheating zone 4 for heating treatment by the ceramic infrared heating plate, and then transported to the high-temperature zone 5, where the ceramic infrared heating plate and the electric heating blower 35 further heat and dry the cloth. Subsequently, it is cooled through the cooling zone 6. The cooling fan 36 in the cooling zone 6 pre-cools the cloth, and then it is transported to the circulation pipe 37. The water pump 34 in the water tank 7 conveys water into the circulation pipe 37 to form a circulation, further promoting cooling; Finally, it is collected by the receiving roller 8 and the first motor 9. The continuous rotation of the first motor 9 enables the cloth to be conveyed and collected.
