Description

Technical Field

[0001] The invention relates to the preparation field of automobile clutch facing sheets, and more particularly to a low-foaming glue dipping device for automobile clutch facing sheets. Background Art

[0002] Automotive clutch facings are key components of the friction clutch driven disc. They are primarily made of non-metallic materials. Their production typically follows a process involving mixing, dissolving, impregnation, drying, pressing, and heat treatment. During the impregnation step, workers dip cord fabric or fiber blend yarn, which serves as the backbone material, into the adhesive tank. Once fully impregnated, the facings are removed and dried.

[0003] During the dipping process of the skeleton material, the glue in the dipping tank will be continuously consumed. Therefore, the glue needs to be continuously replenished during continuous dipping. However, bubbles are easily generated in the glue when replenishing the glue, especially when pouring the glue directly into the dipping tank. The glue will bring in a large amount of air, causing a large number of bubbles in the glue. The bubbles will adhere to the glue layer on the skeleton material, reducing the molding quality of the automobile clutch face. Therefore, a low-foam dipping device for automobile clutch face is provided to improve the above problem. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] In response to the problems existing in the prior art, the purpose of the present invention is to provide a low-foam dipping device for automobile clutch facings, which can realize that during the flow of the flowing glue liquid with bubbles entrained therein, some bubbles collapse during the flow process, some bubbles are eliminated by the defoaming mechanism, and some bubbles are intercepted by the bubble-attaching mesh plate, thereby reducing the amount of bubbles in the glue liquid in contact with the skeleton material and improving the dipping quality of the skeleton material.

[0006] 2. Technical solution

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] The cam is provided with a plurality of through-holes, and the cam is provided with a plurality of through-holes, and the cam is provided with a plurality of through-holes, and the cam is provided with a plurality of through-holes.

[0009] The skeleton material of the automobile clutch facing is placed between two defoaming plates. The negative pressure generator creates a negative pressure environment inside the defoaming plate. When the bubbles in the glue liquid approach the gas-liquid separation membrane, the gas in the bubbles is sucked into the defoaming plate to achieve defoaming. The upward drainage mechanism cooperates with the downward drainage mechanism to achieve the drainage effect on the glue liquid inside the dipping box. The flowing glue liquid flows with the bubbles entrained inside it. Some bubbles collapse during the flow process, some bubbles are eliminated by the defoaming mechanism, and some bubbles are intercepted by the bubble-attached mesh plate, thereby reducing the amount of bubbles in the glue liquid in contact with the skeleton material and improving the dipping quality of the skeleton material.

[0010] Furthermore, an adjusting rod is fixedly connected between one of the defoaming plates and the inner wall of the dipping box, and the other defoaming plate is fixedly connected to the inner bottom end of the dipping box. The adjusting rod can adopt an electric push rod in the existing technology, which is convenient for adjusting the distance between the two defoaming plates according to the size of the skeleton material.

[0011] Furthermore, the end surfaces of the two defoaming plates close to each other are integrated with multiple protrusions, and the multiple protrusions are spaced apart from the multiple through holes. The protrusions can support the skeleton material to prevent the skeleton material from excessively fitting to the defoaming plates during dipping, resulting in uneven dipping.

[0012] Furthermore, the upward drainage mechanism and the downward drainage mechanism both include a motor and a drainage rack. The motor is fixedly connected to the upper end of the glue dipping box. The drainage rack is located in the glue liquid inside the glue dipping box, and the upper end of the drainage rack is fixedly connected to the output shaft of the motor. The motor drives the drainage rack to rotate, and the rotating drainage rack realizes the drainage effect of the glue liquid inside the glue dipping box.

[0013] Furthermore, a drainage baffle is provided on the side of the drainage rack close to the defoaming mechanism. The horizontal plane where the upper end of the drainage baffle is located is lower than the liquid level of the glue in the dipping box. A gap is left between the lower end of the drainage baffle and the inner bottom end of the dipping box. The drainage baffle cooperates with the inner wall of the dipping box to form a flow channel, which can enhance the drainage force of the drainage rack, thereby enhancing the flow effect of the glue.

[0014] Optionally, it also includes a balloon filled with glue liquid, and a plurality of ball-breaking needles are fixedly connected to the end face of the bubble mesh plate near the downward drainage mechanism. When adding glue liquid to the dipping box, the balloon filled with glue liquid is placed between the bubble mesh plate and the downward drainage mechanism, and the downward drainage mechanism drains the balloon to the ball-breaking needles, causing the balloon to be punctured by the ball-breaking needles. The glue liquid flowing in the dipping box squeezes the balloon, causing the glue liquid in the balloon to slowly flow out, completing the addition of glue liquid. Compared with the direct pouring addition method in the prior art, the integration-type addition method of glue liquid can greatly reduce the bubbles generated during the addition process, and the small amount of bubbles generated are intercepted by the bubble mesh plate, thereby realizing low-foam dipping of the automobile clutch facing. In addition, the use of a balloon to hold glue liquid facilitates the quantitative addition of glue liquid and is more conducive to the preservation of unused glue liquid.

[0015] Furthermore, the distance between the drainage baffle plate near the ball-breaking needle and the bottom end of the dipping box is greater than the diameter of the balloon in the expanded state, ensuring that the balloon can pass between the drainage baffle plate and the bottom end of the dipping box.

[0016] Furthermore, the ball-breaking needle is provided with barbs, and the barbs and the ball-breaking needle are formed as one body. The punctured balloon is not easy to separate from the ball-breaking needle under the action of the barbs, so that all the balloons can be taken out together through the bubble mesh plate at a later time.

[0017] Furthermore, the balloon is an elastic sac-shaped body, and bubble-attaching wrinkles are evenly arranged on the surface of the balloon. After the glue in the balloon flows out, it shrinks and becomes smaller. The surface of the balloon in the contracted state is uneven, which can provide space for some bubbles to attach. Moreover, the texture depth of the bubble-attaching wrinkles on the surface of the balloon after shrinkage becomes greater, making it easy for surrounding bubbles to attach to the bubble-attaching wrinkles, and more bubbles can be captured.

[0018] Furthermore, the balloon shrinks after the glue inside it flows out, and the mesh diameter of the bubble-attached mesh plate is smaller than the diameter of the balloon after shrinkage, which can prevent the shrunken balloon from contacting the skeleton material of the automobile clutch face plate through the bubble-attached mesh plate.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) This solution places the skeleton material of the automobile clutch face plate between two defoaming plates. The negative pressure generator creates a negative pressure environment inside the defoaming plate. When the bubbles in the glue liquid approach the gas-liquid separation membrane, the gas in the bubbles is sucked into the defoaming plate to achieve defoaming. The upward drainage mechanism cooperates with the downward drainage mechanism to achieve the drainage effect on the glue liquid inside the dipping box. The flowing glue liquid carries the bubbles entrained inside it. Some bubbles collapse during the flow process, some bubbles are eliminated by the defoaming mechanism, and some bubbles are intercepted by the bubble-attaching mesh plate, thereby reducing the amount of bubbles in the glue liquid in contact with the skeleton material and improving the dipping quality of the skeleton material.

[0022] (2) This solution is to fix an adjustment rod between one of the defoaming plates and the inner side wall of the dipping box, and the other defoaming plate is fixedly connected to the inner bottom end of the dipping box. The adjustment rod is provided to facilitate adjusting the distance between the two defoaming plates according to the size of the skeleton material;

[0023] (3) This solution provides a plurality of protrusions on the end surfaces of the two defoaming plates that are close to each other, and the plurality of protrusions are spaced apart from the plurality of through holes. The protrusions can support the skeleton material, thereby preventing the skeleton material from being excessively attached to the defoaming plates during the dipping process, thereby causing uneven dipping.

[0024] (4) This solution is to fix a motor at the upper end of the dipping box, and the drainage rack is located in the glue liquid inside the dipping box, and the upper end of the drainage rack is fixedly connected to the output shaft of the motor. The motor drives the drainage rack to rotate, and the rotating drainage rack realizes the drainage of the glue liquid inside the dipping box;

[0025] (5) This solution provides a drainage baffle on the side of the drainage rack close to the defoaming mechanism, and the upper end of the drainage baffle is located at a level lower than the liquid level of the glue in the dipping box. A gap is left between the lower end of the drainage baffle and the inner bottom end of the dipping box. The drainage baffle cooperates with the inner wall of the dipping box to form a flow channel, which can enhance the drainage force of the drainage rack and thus enhance the flow effect of the glue;

[0026] (6) This solution sets a balloon filled with glue liquid. When adding glue liquid to the dipping box, the balloon filled with glue liquid is placed between the bubble-attached mesh plate and the downward drainage mechanism. The downward drainage mechanism drains the balloon to the ball-breaking needle, causing the balloon to be punctured by the ball-breaking needle. The glue liquid flowing in the dipping box squeezes the balloon, causing the glue liquid in the balloon to slowly flow out, completing the addition of glue liquid. Compared with the direct pouring addition method in the prior art, the integration-type addition method of the glue liquid can greatly reduce the bubbles generated during the addition process. The small amount of bubbles generated are intercepted by the bubble-attached mesh plate, realizing low-foam dipping of the automobile clutch face plate. In addition, the use of the balloon to hold the glue liquid facilitates the quantitative addition of the glue liquid and is more conducive to the storage of unused glue liquid.

[0027] (7) In the scheme, the distance between the drainage baffle close to the ball breaking needle side and the bottom end of the dipping tank is greater than the diameter of the balloon in the inflated state, so as to ensure that the balloon can pass between the drainage baffle and the bottom end of the dipping tank;

[0028] (8) The scheme sets the barb on the ball breaking needle, and the barb is formed integrally with the ball breaking needle. The balloon pierced by the barb is not easy to separate from the ball breaking needle under the action of the barb, which facilitates the subsequent taking out of all the balloons through the bubble attachment net plate;

[0029] (9) The scheme sets the balloon as an elastic sac-shaped body, and the surface of the balloon is uniformly provided with bubble attachment wrinkles. After the glue solution in the balloon flows out, the balloon shrinks and becomes smaller. The surface of the balloon in the shrunk state is uneven, which can provide a part of bubbles to be attached. The texture depth of the bubble attachment wrinkle on the surface of the balloon after shrinking becomes larger, so that the surrounding bubbles are easy to be attached in the bubble attachment wrinkle, and more bubbles can be captured;

[0030] (10) In the scheme, the balloon shrinks after the glue solution in the balloon flows out. The diameter of the mesh hole on the bubble attachment net plate is smaller than the diameter of the balloon after shrinking, which can prevent the balloon after shrinking from contacting the framework material of the automobile clutch surface sheet.

Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention in specific circumstances.

[0044] Example 1:

[0045] See also Figure 1-8 A low-foaming glue dipping device for automobile clutch facings includes a glue dipping box 1 with glue liquid inside, an upward drainage mechanism is provided on one side of the interior of the glue dipping box 1, and a downward drainage mechanism is provided on the other side of the interior of the glue dipping box 1, and both the upward drainage mechanism and the downward drainage mechanism are fixedly connected to the glue dipping box 1.

[0046] Specifically, such as Figure 5As shown, the upward drainage mechanism and the downward drainage mechanism both include a motor 8 and a drainage rack 9. The motor 8 is fixedly connected to the upper end of the glue dipping box 1. The drainage rack 9 is located in the glue liquid inside the glue dipping box 1, and the upper end of the drainage rack 9 is fixedly connected to the output shaft of the motor 8. The motor 8 drives the drainage rack 9 to rotate, and the rotating drainage rack 9 realizes the drainage effect on the glue liquid inside the glue dipping box 1.

[0047] Among them, such as Figure 1 、 Figure 2 and Figure 5 As shown, a drainage baffle 10 is provided on the side of the drainage rack 9 close to the defoaming mechanism. The horizontal plane where the upper end of the drainage baffle 10 is located is lower than the liquid level of the glue in the dipping box 1. A gap is left between the lower end of the drainage baffle 10 and the inner bottom end of the dipping box 1. The drainage baffle 10 cooperates with the inner wall of the dipping box 1 to form a flow channel, which can enhance the drainage force of the drainage rack 9, thereby enhancing the flow effect of the glue.

[0048] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the bubble-attaching mesh plate 11 is located between the upward drainage mechanism and the downward drainage mechanism, and the side end of the bubble-attaching mesh plate 11 abuts against the inner wall of the dipping box 1, and a defoaming mechanism is provided between the upward drainage mechanism and the bubble-attaching mesh plate 11.

[0049] Specifically, such as Figure 1-5 As shown, the defoaming mechanism includes two defoaming plates 2 arranged perpendicular to the bottom end of the dipping box 1, and the two defoaming plates 2 are parallel to the flow direction of the glue inside the dipping box 1, the defoaming plates 2 are fixedly connected to the inner wall of the dipping box 1, the defoaming plates 2 are hollow plates, and the end faces of the two defoaming plates 2 close to each other are provided with a plurality of through holes connected to the interior thereof, and a gas-liquid separation membrane 4 is fixedly connected to the through holes, and a negative pressure generator 3 is fixedly connected to the outer wall of the dipping box 1, and a hose is connected between the negative pressure generator 3 and the defoaming plates 2.

[0050] The skeleton material of the automobile clutch facing is placed between two defoaming plates 2, and the negative pressure generator 3 makes the inside of the defoaming plate 2 a negative pressure environment. When the bubbles in the glue liquid approach the gas-liquid separation membrane 4, the gas in the bubbles is sucked into the defoaming plate 2 to achieve defoaming. The upward drainage mechanism cooperates with the downward drainage mechanism to achieve the drainage effect of the glue liquid inside the dipping box 1. The flowing glue liquid flows with the bubbles entrained inside it. Some bubbles collapse during the flow process, some bubbles are eliminated by the defoaming mechanism, and some bubbles are intercepted by the bubble-attaching mesh plate 11, thereby reducing the amount of bubbles in the glue liquid in contact with the skeleton material and improving the dipping quality of the skeleton material.

[0051] like Figure 4As shown, an adjusting rod 7 is fixedly connected between one of the defoaming plates 2 and the inner wall of the dipping box 1, and the other defoaming plate 2 is fixedly connected to the inner bottom end of the dipping box 1. The adjusting rod 7 can adopt an electric push rod in the prior art, which is convenient for adjusting the distance between the two defoaming plates 2 according to the size of the skeleton material.

[0052] like Figure 3 As shown, the end surfaces of the two defoaming plates 2 close to each other are integrated with multiple protrusions 5, and the multiple protrusions 5 are spaced apart from the multiple through holes. The protrusions 5 can support the skeleton material to prevent the skeleton material from excessively fitting to the defoaming plates 2 during dipping, resulting in uneven dipping.

[0053] The glue liquid in the immersion tank 1 is squeezed by the ball-breaking needles 12, and the glue liquid in the immersion tank 1 is squeezed by the ball-breaking needles 12, so that the glue liquid in the immersion tank 1 is squeezed out by the ball-breaking needles 12. The glue liquid flowing in the immersion tank 1 squeezes the ball-breaking needles 12, and the glue liquid in the ball-breaking needles 12 slowly flows out, completing the glue liquid addition. Compared with the direct pouring addition method in the prior art, the glue liquid integration type addition method can greatly reduce the bubbles generated during the addition process, and the small amount of bubbles generated are intercepted by the bubble-attached mesh plate 11, thereby realizing low-foaming glue dipping of the automobile clutch facing. In addition, the use of the ball-breaking needle 12 to contain the glue liquid facilitates the quantitative addition of the glue liquid and is more conducive to the storage of unused glue liquid.

[0054] In order to ensure that the balloon 6 can pass between the drainage baffle 10 and the bottom end of the dipping box 1, Figure 5 and Figure 6 As shown, the distance between the drainage baffle 10 on the side close to the ball-breaking needle 12 and the bottom end of the dipping box 1 is greater than the diameter of the balloon 6 in the expanded state.

[0055] In order to avoid the problem that the punctured balloon 6 is separated from the ball-breaking needle 12 and is difficult to clean up later, Figure 6 and Figure 7 As shown, the ball-breaking needle 12 is provided with barbs 13, and the barbs 13 and the ball-breaking needle 12 are formed as one body. The punctured balloon 6 is not easy to separate from the ball-breaking needle 12 under the action of the barbs 13, so that all the balloons 6 can be taken out together through the bubble mesh plate 11 later.

[0056] The balloon 6 is an elastic capsule. Figure 8As shown, the surface of the balloon 6 is uniformly provided with bubble-attached folds 14. After the glue solution in the balloon 6 flows out, the balloon 6 shrinks and becomes smaller. The surface of the balloon 6 in the shrunk state is uneven, and can provide a part of the bubbles to be attached. The texture depth of the bubble-attached folds 14 on the surface of the balloon 6 after shrinking becomes larger, so that the surrounding bubbles are easily attached to the bubble-attached folds 14, and more bubbles can be captured.

[0057] In order to avoid that the balloon 6 is attached to the framework material of the automobile clutch facing sheet, the balloon 6 shrinks after the glue solution in the balloon 6 flows out. The mesh diameter of the bubble-attached mesh plate 11 is smaller than the diameter of the balloon 6 after shrinking, so that the balloon 6 after shrinking can be prevented from contacting the framework material of the automobile clutch facing sheet through the bubble-attached mesh plate 11.

[0058] In use, the framework material of the automobile clutch facing sheet is placed between the two defoaming plates 2. The negative pressure generator 3 makes the inside of the defoaming plate 2 a negative pressure environment. When the bubbles in the glue solution approach the gas-liquid separation membrane 4, the gas in the bubbles is sucked into the inside of the defoaming plate 2, so that defoaming is realized. The upward drainage mechanism cooperates with the downward drainage mechanism to realize the drainage effect of the glue solution in the glue dipping tank 1. The flowing glue solution carries the bubbles mixed in the inside of the glue solution to flow. Part of the bubbles collapse in the flowing process. Part of the bubbles are eliminated through the defoaming mechanism. Part of the bubbles are intercepted by the bubble-attached mesh plate 11, so that the amount of the bubbles in the glue solution contacting the framework material is reduced, and the glue dipping quality of the framework material is improved.

[0059] When the glue solution is supplemented into the glue dipping tank 1, the balloon 6 containing the glue solution is put between the bubble-attached mesh plate 11 and the downward drainage mechanism. The downward drainage mechanism drains the balloon 6 to the balloon breaking needle 12, so that the balloon 6 is pierced by the balloon breaking needle 12. The flowing glue solution in the glue dipping tank 1 extrudes the balloon 6, so that the glue solution in the balloon 6 slowly flows out, and the glue solution addition is completed. The blending addition mode of the glue solution can greatly reduce the bubbles generated in the addition process, compared with the direct pouring addition mode in the prior art. The small amount of bubbles generated are intercepted by the bubble-attached mesh plate 11, so that low-bubble type glue dipping of the automobile clutch facing sheet is realized. In addition, the balloon 6 containing the glue solution is convenient for quantitative addition of the glue solution, and is more conducive to the preservation of the unused glue solution. The pierced balloon 6 is not easy to separate from the balloon breaking needle 12 under the action of the barb 13, so that all the balloons 6 can be taken out through the bubble-attached mesh plate 11 in the later stage.

[0060] The above description is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical solution and the improvement concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
