Description

Technical Field

[0001] The invention relates to the field of automobile brake lining recycling, in particular to a device for recycling automobile brake lining production waste. Background Art

[0002] Brake pad friction materials primarily consist of organic, metallic, and inorganic components. Organic components are typically binders such as resins, such as phenolic resin, which bind the other components together, ensuring the brake pads have the appropriate strength and friction properties. Metallic components include copper, iron, and tin. Copper improves the friction material's thermal conductivity and wear resistance. Inorganic components include ceramic fibers and mineral fibers. Ceramic fibers enhance the friction material's high-temperature resistance. Recycled brake pad friction material can be incorporated into new materials in proportion.

[0003] The existing patent (CN215388434U) is a double-layer negative pressure dust removal and recovery device, which involves the field of brake pad raw material dust removal. The double-layer negative pressure dust removal and recovery device includes a dust source, an internal dust removal mechanism, an external dust removal mechanism, an exhaust motor assembly, a centrifugal dust separator, and a trolley. The internal dust removal mechanism includes a sealed inner cover, an internal dust removal duct, and internal dust removal pipeline accessories. The internal dust removal mechanism is responsible for the first dust removal of the dust source; the external dust removal mechanism includes a sealed outer cover, an external dust removal duct, and external pipeline accessories. The external dust removal mechanism is responsible for the second dust removal of the dust source; the centrifugal dust separator and the trolley are responsible for collecting brake pad raw materials in the air.

[0004] This technical solution utilizes an internal dust removal mechanism, an external dust removal mechanism, an exhaust motor assembly, a centrifugal dust separator, and a trolley to recycle brake pad raw materials from the air. This improves environmental issues in the brake pad manufacturing process and saves a significant amount of brake pad raw materials. In actual production, waste is generated during the high-temperature bonding step between the brake friction material and the lining. This can occur due to cracks in the friction material or a loose connection between the friction material and the lining. Separating the friction material from the lining can be difficult due to the partial connection between the friction material and the lining. Summary of the Invention

[0032] like Figure 1-8 As shown, a vehicle brake lining production waste recycling device includes a clamping mechanism 1 for clamping the vehicle brake lining, a cutting mechanism 2 for cutting the vehicle brake lining, and a squeezing mechanism 3 for squeezing the vehicle brake lining into pieces. The cutting mechanism 2 includes a rotating shaft 201 driven for rotation by a power unit 204. The outer surface of the rotating shaft 201 is fixedly mounted with cutting discs 202 distributed along the through holes of the vehicle brake lining lining. The cutting discs 202 are used to cut the friction portion of the vehicle brake lining and the protrusions of the vehicle brake lining lining portion. The squeezing mechanism 3 includes telescopic pressing blocks 301 arranged on both sides of the vehicle brake lining lining portion. First, the vehicle brake lining is cut by the cutting mechanism 2, so that there is enough space for the friction portion in the vehicle brake lining to be deformed. Then, the vehicle brake lining is squeezed and crushed by the squeezing mechanism 3, so that the friction portion and the lining portion are deformed and separated.

[0033] The clamping mechanism 1 includes extrusion plates 101 symmetrically arranged on both sides of the automobile brake lining lining. The outer sides of the two extrusion plates 101 are slidably connected with a connecting frame 102. The connecting frame 102 is provided with an extension plate 103 extending outward. The middle part of the extension plate 103 is rotatably connected with a double-headed threaded shaft 104. The double-headed threaded shaft 104 is threadedly connected to the two extrusion plates 101. By rotating the double-headed threaded shaft 104, the extrusion plates 101 can be driven to move toward each other, thereby squeezing and fixing the automobile brake lining.

[0034] The cutting mechanism 2 includes a fixed frame 203, a rotating shaft 201 rotatably connected to the middle of the fixed frame 203, and a power unit 204 that drives the rotating shaft 201 to rotate, which is fixedly installed on the outer surface of the fixed frame 203. Through this arrangement, the cutting disc 202 can rotate along a specified route to complete the cutting of the automobile brake lining.

[0035] A slider 105 is fixedly installed above the clamping mechanism 1, and a guide rail 4 is provided on the outer surface of the slider 105. A bracket 5 is fixedly installed on the outer surface of the guide rail 4. A friction roller 6 is provided inside the guide rail 4 to rotate and drive the slider 105 to move. The friction roller 6 can rub against the slider 105 so that the clamping mechanism 1 can be moved.

[0036] The friction roller 6 includes a continuous motion group and a separate control group that can be controlled separately. The friction roller 6 extends to the top of the guide rail 4 through the central axis, and a sprocket is set at the top of the central axis. The continuous motion group is transmitted through a group of chains, and the separate control group is transmitted through a separate group of chains.

[0037] Guide rail 4 is provided with a protrusion 7 located at the individual control group of friction rollers 6. Protrusion 7 is located at the center of the automobile brake lining. An extension rod 8 is rotatably connected to the outer surface of protrusion 7. A gear ring 9 is fixedly connected to the outer surface of one extension rod 8. A power source 10 that drives the gear ring 9 to rotate is fixedly mounted on the outer side of guide rail 4. A fixed frame 203 is fixedly mounted below a symmetrical set of extension rods 8. This arrangement enables the automobile brake lining to be moved concentrically with protrusion 7, and the swinging of extension rods 8 allows the automobile brake lining to be manipulated. A telescopic pressure block 301 is fixedly mounted below the extension rods 8.

[0038] The fixed frame 203 includes an electromagnetic telescopic sleeve 205 fixedly installed at the bottom end, and the fixed frame 203 is fixedly connected to the free end of the electromagnetic telescopic sleeve 205. Since the cutting disc 202 needs to cut into the interior of the automobile brake lining, the electromagnetic telescopic sleeve 205 can drive the cutting disc 202 to move. The fixed end of the electromagnetic telescopic sleeve 205 is fixedly connected to the extension rod 8. Positioning holes 106 are opened on both sides of the slider 105. The guide rail 4 is located inside the independent control group of the friction roller 6 and is inlaid with a positioning telescopic rod 107. The positioning telescopic rod 107 can be inserted into the positioning hole 106 when aligned with the positioning hole 106 to limit the slider 105 from moving.

[0039] The bracket 5 is provided with an annular portion 51 and a partial supporting portion 52 on the outside of the telescopic pressure block 301. The fixed end of the telescopic pressure block 301 is slidably connected and in contact with the inner wall of the annular portion 51. By providing the annular portion 51, the telescopic pressure block 301 can be limited to prevent the telescopic pressure block 301 from expanding outward.

[0040] The outer surface of the rotating shaft 201 is sleeved with a limiting sleeve 206 , which is located between two adjacent groups of cutting discs 202 . This arrangement can limit the position of the cutting discs 202 and prevent the cutting discs 202 from moving.

[0041] It also includes a grinding wheel 11 for grinding automobile brake linings. The grinding wheel 11 is located in front of the cutting disc 202. A fixing frame 12 is provided on the outside of the grinding wheel 11. The outer surface of the fixing frame 12 is fixedly provided with a power part 13 for driving the grinding wheel 11 to rotate. The rotation of the grinding wheel 11 rubs the friction part in the automobile brake lining, so that the friction part can be formed into powder, reducing the subsequent processing.

[0042] An electromagnetic telescopic rod 14 is fixedly mounted on the outer side of the fixing frame 12, and the fixed end of the electromagnetic telescopic rod 14 is fixedly mounted below the extension rod 8. This arrangement enables the grinding wheel 11 to swing and rub along the automobile brake lining.

[0043] The grinding wheel 11 is located below the guide rail 4. There are multiple grinding wheels 11, and the multiple grinding wheels 11 are evenly distributed. An elastic telescopic rod 15 is fixedly installed below the grinding wheel 11, and the bottom end of the elastic telescopic rod 15 is flush with the bottom end of the bracket 5. Through such an arrangement, multiple groups of grinding wheels 11 can be used to form continuous operation, thereby achieving the effect of uninterrupted movement and continuous grinding of the automobile brake lining.

[0044] During use, the cutting mechanism 2 is used to cut the through hole of the lining of the automobile brake lining without cutting off the automobile brake lining, and the automobile brake lining is squeezed by the squeezing mechanism 3, so that the lining part of the automobile brake lining is deformed and the friction part of the automobile brake lining is broken to complete the separation of the lining and the friction part. The separated friction part can be reused after reducing the particle size through the crushing mechanism.

[0045] The automobile brake lining isomorphic clamping mechanism 1 is fixed and placed inside the guide rail 4. The clamping mechanism 1 is driven to move along the guide rail 4 by the friction roller 6. First, the friction part is polished to be flush with the lining by the grinding wheel 11, and then moved to the cutting mechanism 2 and the extrusion mechanism 3 for cutting and crushing. Through this setting, the friction part of the protruding part can be processed first and processed into powder to reduce the subsequent processing steps.

[0046] Among them, when the clamping mechanism 1 moves to the cutting mechanism 2 and the extrusion mechanism 3, the positioning telescopic rod 107 is inserted into the inside of the positioning hole 106, and the friction roller 6 is individually controlled to stop moving, and then the corresponding process, the continuous friction roller 6 keeps moving, driving the clamping mechanism 1 to grind through multiple continuous grinding wheels 11, so that the grinding process can be continued during the cutting or extrusion fragmentation process, reducing the waiting time. When the clamping mechanism 1 moves to contact the clamping mechanism 1 in front that no longer moves, the friction roller 6 idles to keep the position of the clamping mechanism 1 unchanged.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.
