Description

Technical Field

[0001] This utility model relates to the field of brake pad production material technology, specifically to an automatic batching and weighing mechanism for brake pad mixing. Background Technology

[0002] Automotive brake pads, also known as brake discs, are friction materials fixed to the brake drum or brake disc that rotates with the wheel. The production and processing of brake pads requires mixing various powders first, and then hot pressing them into shape. The mixing ratio of the various powders has a significant impact on the quality of the brake pads. Therefore, before mixing, it is necessary to weigh and measure each of the various powders that are about to be put into the mixing tank.

[0003] Currently, the widely used batching and weighing methods include manual weighing and automatic weighing. Manual weighing has the advantage of high accuracy, but it has the disadvantages of low efficiency and being time-consuming and labor-intensive. Automatic weighing, on the other hand, uses an automatic weighing mechanism to weigh the powder discharged from the discharge hopper. Once the set value is reached, the valve of the discharge hopper is closed, and the weighed powder is then discharged to the mixing mechanism for mixing. It has the advantages of high efficiency and low labor costs. However, since the powder weighing and mixing are carried out in different containers, the powder may not be completely transferred during the transfer process after weighing. Some powder may stick to the inner wall of the weighing container, resulting in poor accuracy of the final powder mixing ratio.

[0004] Therefore, an automatic batching and weighing mechanism for mixing brake pads is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic batching and weighing mechanism for mixing brake pads in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An automatic batching and weighing mechanism for mixing brake pads includes a base, a U-shaped enclosure fixedly mounted on the top surface of the base with its opening facing forward, an mounting plate fixedly mounted on the upper part of the back side of the inner wall of the U-shaped enclosure, and several storage bins fixedly mounted on the surface of the mounting plate, the storage bins being evenly distributed laterally. A transverse movement drive assembly is provided between the left and right side walls of the U-shaped enclosure, and an annular weighing mechanism is fixedly mounted on the moving part of the transverse movement drive assembly. A mixing tank is slidably mounted against the inner surface of the annular weighing mechanism, and a placement ring is fixedly mounted on the outer side of the mixing tank, the placement ring being placed against the top surface of the annular weighing mechanism. Limiting support assemblies for limiting and flexibly supporting the placement ring are provided on the surfaces of the annular weighing mechanism and the placement ring. A lifting drive assembly is provided on the back and right side of the inner wall of the U-shaped enclosure, and a sealing stirring mechanism is fixedly mounted on the moving part of the lifting drive assembly. Solenoid valves are provided at the bottom of both the storage bins and the mixing tank, and an electrical control box is fixedly mounted on the outer surface of the U-shaped enclosure.

[0008] Furthermore, the annular weighing mechanism includes a mounting ring, which is fixedly mounted on the surface of the moving part of the transverse drive assembly. A weighing sensor is fixedly mounted on the top surface of the mounting ring, and a support ring is fixedly mounted on the top surface of the weighing sensor. The placement ring is placed against the top surface of the support ring, and the mixing tank is slidably disposed against the inner wall side of the mounting ring and the support ring.

[0009] Furthermore, the number of weighing sensors is several and they are distributed in a uniform ring array, and the mounting ring is a hollow structure.

[0010] Furthermore, the limiting support assembly includes a lower mounting block and an upper mounting block. The lower mounting block is fixedly mounted on the side of the mounting ring, and the upper mounting block is fixedly mounted on the side of the placement ring. An electric telescopic rod is vertically fixedly mounted on the surface of the lower mounting block, and a locking block is fixedly connected to the telescopic end of the electric telescopic rod. A locking groove is opened on the bottom surface of the upper mounting block, and the locking block is slidably disposed against the inner wall surface of the locking groove. The height of the locking groove is greater than the height of the locking block. When the inside of the mixing tank is empty, there is a gap between the top surface of the locking block and the top surface of the inner wall of the locking groove. The number of limiting support assemblies is two, and they are arranged symmetrically on the left and right.

[0011] Furthermore, the sealing and stirring mechanism includes a cover plate, which is fixedly installed on the surface of the moving part of the lifting drive assembly. A motor is fixedly installed on the top surface of the cover plate, and a rotating shaft is fixedly installed at the output end of the motor. The rotating shaft is rotatably installed on the bottom surface of the cover plate, and a stirring paddle is fixedly installed on the surface of the rotating shaft.

[0012] Furthermore, a raised ring is fixedly installed on the top of the inner wall surface of the mixing tank.

[0013] The beneficial effects of this utility model are as follows:

[0014] As the mixing drum moves to the right via the lateral drive assembly, powder from different storage bins is sequentially discharged into the mixing drum. A ring-shaped weighing mechanism monitors the increased weight, thereby controlling the amount of different types of powder added. After the powder is added, the mixing drum is moved by the lateral drive assembly to directly below the sealing mixing mechanism. A lifting drive assembly then moves the sealing mixing mechanism downwards, allowing it to enter the mixing drum and seal its top surface. At this point, a limiting support assembly provides limiting support for the placement ring, preventing its bottom surface from contacting the top surface of the ring-shaped weighing mechanism. This avoids vibrations during mixing that could damage the ring-shaped weighing mechanism due to repeated weighing measurements, while also ensuring the stability of the mixing drum during operation. This allows the mixing drum to function as both a weighing and mixing container. Even though some powder may still adhere to the walls after thorough mixing, the accurate proportions of the discharged powder ensure the final quality of the brake pads produced.

[0025] like Figures 1 to 4As shown, an automatic batching and weighing mechanism for brake pad mixing includes a base 1. A U-shaped partition 2 is fixedly installed on the top surface of the base 1, with the opening of the U-shaped partition 2 facing forward. An mounting plate 3 is fixedly installed on the upper part of the back of the inner wall of the U-shaped partition 2. Storage bins 4 are fixedly installed on the surface of the mounting plate 3. The number of storage bins 4 is several and evenly distributed laterally. A transverse movement drive assembly 5 is provided between the left and right side walls of the U-shaped partition 2. An annular weighing mechanism 6 is fixedly installed on the moving part of the transverse movement drive assembly 5. The inner surface of the annular weighing mechanism 6 is slidably fitted to the surface. There is a mixing tank 7, and a placement ring 8 is fixedly installed on the outer side of the mixing tank 7. The placement ring 8 is placed against the top surface of the annular weighing mechanism 6. The surfaces of the annular weighing mechanism 6 and the placement ring 8 are provided with limiting support components 9 for limiting and flexibly supporting the placement ring 8. The back and right side of the inner wall of the U-shaped enclosure 2 are provided with lifting drive components 10. The moving parts of the lifting drive components 10 are fixedly installed with a sealing mixing mechanism 11. The bottom of the storage tank 4 and the mixing tank 7 are both provided with solenoid valves 12. The outer surface of the U-shaped enclosure 2 is fixedly installed with an electrical control box 13.

[0026] More specifically, during the process of the mixing tank 7 moving to the right by the transverse drive assembly 5, the powder from different storage tanks 4 is sequentially discharged directly into the mixing tank 7. The increased weight is monitored by the annular weighing mechanism 6. When the weight increase reaches the corresponding set value, the electrical control box 13 sends a signal to the solenoid valve 12 on the upper side of the mixing tank 7, causing the solenoid valve 12 to close. Then, the electrical control box 13 controls the transverse drive assembly 5, causing the mixing tank 7 to move directly below the next storage tank 4. Then, it controls the solenoid valve 12 at the bottom of the storage tank 4 to open, thus completing the sequential weighing and addition of powder. After the powder is added, the mixing tank 7 is moved by the transverse drive assembly 5 to directly below the sealing mixing mechanism 11. The lifting drive assembly 10 then drives the sealing mixing mechanism 11. 1. The downward movement allows the sealing stirring mechanism 11 to enter the mixing tank 7 and seal the top surface of the mixing tank 7. At this time, the limiting support component 9 provides limiting support for the placement ring 8, so that the bottom surface of the placement ring 8 no longer contacts the top surface of the annular weighing mechanism 6. This avoids the vibration generated by the sealing stirring mechanism 11 during the mixing operation from affecting the annular weighing mechanism 6, which would cause the annular weighing mechanism 6 to be damaged due to repeated weighing measurements. At the same time, it ensures the stability of the mixing tank 7 when the sealing stirring mechanism 11 is working, so that the mixing tank 7 can function as both a weighing container and a mixing container. When the powder is discharged after thorough mixing, although there is still some powder adhering to the wall, the different powders have been thoroughly mixed, so the proportion of the discharged powder can be ensured to be accurate, thereby ensuring the quality of the final brake pads.

[0027] The annular weighing mechanism 6 includes a mounting ring 601, which is fixedly mounted on the surface of the moving part of the transverse drive assembly 5. A weighing sensor 602 is fixedly mounted on the top surface of the mounting ring 601, and a support ring 603 is fixedly mounted on the top surface of the weighing sensor 602. A placement ring 8 is placed against the top surface of the support ring 603. The mixing tank 7 is slidably disposed against the inner wall side of the mounting ring 601 and the support ring 603.

[0028] Specifically, the mixing tank 7 can be suspended by the placement ring 8. After the powder enters the mixing tank 7, the change in weight is transmitted to the support ring 603. The support ring 603 squeezes the weighing sensor 602 to generate an electrical signal. The electrical signal generated by the weighing sensor 602 is transmitted to the electrical control box 13. After being processed by the electrical control box 13, it is used to control the transverse drive assembly 5, the solenoid valve 12 and other related structures to perform their actions.

[0029] The number of weighing sensors 602 is several and they are distributed in a uniform ring array. The mounting ring 601 is a hollow structure.

[0030] Specifically, multiple evenly distributed weighing sensors 602 are used to achieve multi-point measurement. The acquired data are averaged and calculated, resulting in higher accuracy of the final value. This is beneficial to improving the measurement accuracy of the powder mass in the mixing tank 7 by the ring weighing mechanism 6, and ultimately improving the accuracy of the powder proportioning. The hollow structure of the mounting ring 601 is used to place the wire.

[0031] The limiting support assembly 9 includes a lower mounting block 901 and an upper mounting block 902. The lower mounting block 901 is fixedly mounted on the side of the mounting ring 601, and the upper mounting block 902 is fixedly mounted on the side of the placement ring 8. An electric telescopic rod 903 is vertically fixedly mounted on the surface of the lower mounting block 901. A locking block 904 is fixedly connected to the telescopic end of the electric telescopic rod 903. A locking groove 905 is opened on the bottom surface of the upper mounting block 902. The locking block 904 slides against the inner wall surface of the locking groove 905. The height of the locking groove 905 is greater than the height of the locking block 904. When the inside of the mixing tank 7 is empty, there is a gap between the top surface of the locking block 904 and the top surface of the inner wall of the locking groove 905. There are two limiting support assemblies 9, which are arranged symmetrically on the left and right.

[0032] Specifically, when the mixing tank 7 is empty, the locking block 904 and the locking groove 905 do not press against each other vertically. Therefore, when powder is added to the mixing tank 7, the mixing tank 7 can apply the pressure generated by the powder to the weighing sensor 602 through the placement ring 8, avoiding the locking block 904 supporting the placement ring 8 and causing weighing data errors. When the sealing mixing mechanism 11 needs to be moved down for mixing, the extension end of the electric telescopic rod 903 drives the locking block 904 to rise. The top surface of the locking block 904 fits against the top surface of the inner wall of the locking groove 905, thereby fully supporting the placement ring 8 and preventing the bottom surface of the placement ring 8 from contacting the top surface of the support ring 603. The placement ring 8 is supported and limited by the left and right symmetrically arranged limiting support components 9, so that when the sealing mixing mechanism 11 rotates, the placement ring 8 and the mixing tank 7 remain stable and will not cause the weighing sensor 602 to work repeatedly.

[0033] The sealing stirring mechanism 11 includes a cover plate 111, which is fixedly installed on the surface of the moving part of the lifting drive assembly 10. A motor 112 is fixedly installed on the top surface of the cover plate 111, and a rotating shaft 113 is fixedly installed at the output end of the motor 112. The rotating shaft 113 is rotatably installed on the bottom surface of the cover plate 111, and a stirring paddle 114 is fixedly installed on the surface of the rotating shaft 113.

[0034] Specifically, the lifting drive assembly 10 moves the cover plate 111 downwards, so that the cover plate 111 covers the top surface of the mixing tank 7. The rotating shaft 113 and the stirring paddle 114 enter the interior of the mixing tank 7. The output end of the motor 112 drives the rotating shaft 113 and the stirring paddle 114 to rotate, thereby fully mixing the different types of powders loaded in the mixing tank 7.

[0035] A raised ring 14 is fixedly installed on the top of the inner wall surface of the mixing tank 7.

[0036] Specifically, the convex ring 14 increases the contact area between the top of the mixing tank 7 and the bottom surface of the cover plate 111, thereby effectively improving the sealing performance and enhancing the stability of the cover plate 111.

[0037] In summary: As the mixing tank 7 moves to the right via the transverse drive assembly 5, the powder from different storage tanks 4 is sequentially discharged directly into the mixing tank 7. The increased weight is monitored by the annular weighing mechanism 6, thereby controlling the amount of different types of powder added. After the powder is added, the mixing tank 7 is moved by the transverse drive assembly 5 to directly below the sealing mixing mechanism 11. The lifting drive assembly 10 then moves the sealing mixing mechanism 11 downward, allowing it to enter the mixing tank 7 and seal the top surface. At this point, the limiting support assembly 9 secures the placement ring 8. The limit support prevents the bottom surface of the placement ring 8 from contacting the top surface of the annular weighing mechanism 6, thus avoiding damage to the annular weighing mechanism 6 caused by repeated weighing measurements due to vibrations generated during the mixing operation of the sealed mixing mechanism 11. At the same time, it ensures the stability of the mixing tank 7 when the sealed mixing mechanism 11 is working, so that the mixing tank 7 functions as both a weighing container and a mixing container. When the powder is discharged after thorough mixing, although some powder may still adhere to the wall, the different powders have been thoroughly mixed, thus ensuring the accurate ratio of the discharged powder and the quality of the final brake pads.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
