[0048] The present invention is further described in detail below in conjunction with embodiments:

[0049] Example 1

[0050] like Figure 1-9 As shown, the present invention provides a method for preparing an impact-resistant automobile clutch facing sheet, and the method for preparing an impact-resistant automobile clutch facing sheet comprises the following steps:

[0051] Step 1: Prepare raw materials;

[0052] Step 2: Fiber processing;

[0053] Step 3: Gluing and cutting;

[0054] Step 4: Finished product grinding;

[0055] Step 5: Check the packaging.

[0056] The second step also includes the following steps:

[0057] A1: Wrap the nitrile rubber thread on the surface of the plant fiber through a core wrapping machine;

[0058] A2: After the core wrapping is completed, impurities are removed and the cored wires whose quality is lower than the production requirements during the core wrapping process are removed;

[0059] A3: After the impurities are removed, the cored wire is subjected to high twisting by a high twisting machine;

[0060] A4: After high twisting, spray the surface with impact-resistant coating and then let it air dry naturally;

[0061] A5: After the yarn is completely air-dried, the high-twisted yarn is woven into cloth.

[0062] Step three also includes the following steps:

[0063] B1: Cut the finished cloth into round pieces of equal diameter according to production needs;

[0064] B2: Bond the round cloth with adhesive. The thickness of the adhesive should be one third to one sixth of the thickness of the round cloth. Bond until the thickness meets the production requirements.

[0065] B3: Allow the stacked round pieces of fabric to air dry naturally;

[0066] B4: After air drying, the laminated circular cloth is slotted by the cutting device 1.

[0067] Step 4 also includes the following steps:

[0068] C1: Compare and test qualified products with tested products at the same time;

[0069] C2: Products that pass the inspection are packaged and put into storage.

[0070] In this embodiment, the staff prepares the corresponding raw materials, such as nitrile rubber thread, plant fiber, impact-resistant coating and other related raw materials, and winds the nitrile rubber thread on the surface of the plant fiber through a core-wrapping machine. After the core-wrapping is completed, the staff removes impurities and removes the core-wrapped wire whose quality is lower than the production requirement during the core-wrapping process. After the impurities are removed, the core-wrapped wire is high-twisted by a high-twisting machine. After the high-twisting is completed, the high-twisted wire is sprayed with impact-resistant coating on its surface and then naturally air-dried. After it is completely air-dried, the high-twisted wire is woven into cloth through a weaving machine. The finished cloth is cut into round cloths of equal diameter according to production needs, and the round cloths are bonded by adhesive. The thickness of the adhesive is one-third to one-sixth of the thickness of the round cloth, and the thickness is bonded to meet the production requirements. After lamination, the round cloth is naturally air-dried again until the adhesive solidifies. After completion, the laminated circular cloth is placed on the surface of the elastic pad 136 set on the surface of the base 131. After placement, the motor 134 is started to make the threaded column 133 rotate at a uniform speed, thereby causing the internal thread lifting plate 132 to move. During the displacement, the laminated circular cloth will be clamped, thereby completing the fixation of the laminated circular cloth. The staff controls the electric telescopic rod 14, and drives the cutting knife 15 to move downward through the connecting plate 16. The laminated circular cloth is cut by the cutting knife 15 to cut out the corresponding groove. The cut cloth will pass through the opening of the dividing plate 12 and fall under the dividing plate 12. After cutting, in order to ensure that the internal and external thickness meets the production requirements, if it is too thick, it will be ground. The prepared product will be compared with the qualified product at the same time, and the qualified product will be packaged and put into storage.

[0071] Example 2

[0072] like Figure 1-9 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, a cooling mechanism 2 is arranged on the top of the cutting device 1, and the cooling mechanism 2 includes a water tank 28, and a cooling shell 21 is fixedly connected to the surface of the water tank 28, and a cooling plate 29 is arranged on the top of the water tank 28. A fan 23 is arranged inside the cooling shell 21, and a columnar air duct 22 is arranged on one side of the fan 23, and a rectangular air duct 24 is arranged on the other side of the fan 23. One end of the rectangular air duct 24 extends to the inner cavity of the cooling shell 21, and the bottom of the water tank 28 A circulating water pipe 25 is fixedly connected, and a water pump 30 is arranged on the surface of the circulating water pipe 25. An evaporative wet curtain 27 is arranged at the bottom of the inner wall of the cooling shell 21. A water pipe 31 is fixedly connected to the bottom of the water tank 28, and a water pump 32 is arranged on the surface of the water pipe 31. A water distributor 33 is arranged at the other end of the water pipe 31. A return water pipe 26 is fixedly connected to the inside of the cooling shell 21, and the other end of the return water pipe 26 is fixedly connected to the back side of the water tank 28. A water pump 34 is arranged on the surface of the return water pipe 26 and on the back side of the cooling shell 21.

[0073] In this embodiment, the fan 23 is started to realize air circulation between the cooling shell 21 and the cutting shell 11 through the rectangular air duct 24 and the cylindrical air duct 22. The No. 1 water pump 30 is started to allow the water inside the water tank 28 to circulate in the circulating water pipe 25. During the circulation process, the heat in the air can be cooled by conduction. The No. 2 water pump 32 is started to supply the water inside the water tank 28 to the water distributor 33 through the water pipe 31. The water distributor distributes water to the evaporative wet curtain 27, so that water is attached to the surface of the evaporative wet curtain 27. The air passes through the evaporative wet curtain 27, and the water evaporates and absorbs heat, thereby achieving a cooling effect. For the water accumulated at the bottom of the cooling shell 21, the No. 3 water pump 34 is started regularly to return the water accumulated at the bottom of the cooling shell 21 to the water tank 28 through the return pipe 26 to avoid wasting water resources. The setting of the refrigeration plate 29 can cool the water stored in the water tank 28, thereby improving the cooling effect to a certain extent.

[0074] Example 3

[0075] like Figure 1-9 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the rectangular air duct 24 includes an air duct body 241, the inner wall of the air duct body 241 is fixedly connected to a fixed shell 242, the inner wall of the fixed shell 242 is fixedly connected to a limiting rod 247, the surface of the limiting rod 247 is movably sleeved with a slider 244, the top of the slider 244 and the outside of the limiting rod 247 is fixedly connected with an elastic shell 245, the inner cavity of the elastic shell 245 is filled with an elastic soft bag 246, one side of the slider 244 extends to the outside of the fixed shell 242 and is fixedly connected with a filter plate 243, and the surface of the air duct body 241 overlaps the surface of the circulating water pipe 25.

[0076] In this embodiment, when air circulates in the duct body 241, the inner cavity shape of the duct body 241 has a good guiding effect on the air, so that the air moves along the inner wall of the duct body 241, and finally passes through the filter plate 243 and then circulates. At the same time, a certain upward force is applied to the filter plate 243, so that the filter plate 243 drives the slider 244 to displace on the surface of the limit rod 247, and a certain pressure is applied to the elastic shell 245 and the elastic soft bag 246. When the air stops circulating, the thrust on the filter plate 243 is lost. Under the action of the rebound force of the elastic shell 245 and the elastic soft bag 246, the filter plate 243 is driven to displace through the slider 244, so that the impurities attached to the surface of the filter plate 243 are shaken off, and the air passes through the filter plate 243 multiple times, thereby achieving the effect of purifying the air.

[0077] Example 4

[0078] like Figure 1-9As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the cutting device 1 includes a cutting shell 11, a dividing plate 12 is fixedly connected to the inner wall side of the cutting shell 11, a fixing mechanism 13 is provided on the top of the dividing plate 12, an electric telescopic rod 14 is provided on the top of the inner wall of the cutting shell 11, a connecting plate 16 is fixedly connected to the bottom of the electric telescopic rod 14, a cutting knife 15 is fixedly connected to the bottom of the connecting plate 16, and the other end of the cylindrical air duct 22 extends to the interior of the cutting shell 11.

[0079] In this embodiment, the laminated circular cloth is fixed by the fixing mechanism 13, and then the electric telescopic rod 14 is controlled to drive the cutting knife 15 to move downward through the connecting plate 16, and the laminated circular cloth is cut by the cutting knife 15 to cut out the corresponding grooves. The cut cloth will pass through the openings provided inside the dividing plate 12 and fall under the dividing plate 12. The staff regularly collects the cloth stored under the dividing plate 12 for recycling.

[0080] Example 5

[0081] like Figure 1-9 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the fixing mechanism 13 includes a base 131, a motor 134 is arranged inside the base 131, a threaded column 133 is fixedly connected to the output end of the motor 134, the surface of the threaded column 133 is threadedly connected to the internal thread lifting plate 132, the surface of the internal thread lifting plate 132 extends to the outside of the base 131, the surfaces of the base 131 and the internal thread lifting plate 132 are both fixedly connected to the elastic pad 136, the top of the base 131 is provided with a sealing mechanism 135, the sealing mechanism 135 includes a sealing shell 1351, the inner wall of the sealing shell 1351 is fixedly connected to a sealing gasket 1354, the surface of the sealing gasket 1354 is fixedly connected to a cross elastic paddle 1355, the top of the sealing shell 1351 is fixedly connected to a scraper 1353, the inner wall of the sealing shell 1351 is fixedly connected to a chemical fiber brush 1352, and the sealing shell 1351 is fixedly connected to the top of the base 131.

[0082] In this embodiment, the laminated circular cloth is placed on the surface of the elastic pad 136 provided on the surface of the base 131. After the placement is completed, the motor 134 is started to make the threaded column 133 rotate at a uniform speed, thereby causing the internal thread lifting plate 132 to move. During the displacement process, the laminated circular cloth will be clamped, thereby completing the fixation of the laminated circular cloth, wherein the elastic pad 136 will contact the laminated circular cloth, and the elastic pad 136 itself will protect the surface of the laminated circular cloth through its own elasticity, thereby avoiding scratches on the surface of the laminated circular cloth during the fixing process. During the lifting and lowering process of the internal thread lifting plate 132, The scraper 1353 can scrape off the accumulated impurity particles on the surface of the internal thread lifting plate 132. The chemical fiber brush 1352 contacts and rubs with the dust particles on the surface of the internal thread lifting plate 132, and static electricity is generated during the friction process, which adsorbs the dust. The setting of the sealing gasket 1354 can effectively prevent dust from entering the base 131, and the resilience of the cross elastic paddle 1355 can further improve the tightness between the sealing gasket 1354 and the internal thread lifting plate 132, thereby improving the sealing effect. The multi-faceted settings can effectively reduce the influence of dust on the threaded transmission between the threaded column 133 and the internal thread lifting plate 132.
