Description

Technical Field

[0001] This utility model relates to the field of transmission device technology, specifically a conveying device for conveying waste materials from automotive parts sheet metal stamping. Background Technology

[0002] In the automotive manufacturing industry, sheet metal stamping is one of the core processes used to produce various body structural parts and body panels. During this process, the die-cutting process generates a large amount of scrap metal. To achieve efficient resource utilization, reduce raw material consumption, and minimize energy waste, recycling and reusing this stamping waste has become an industry consensus and a necessary measure. The efficient and smooth transport of the generated waste from the stamping station to subsequent centralized processing or recycling areas is a crucial link in the waste recycling process.

[0003] Currently, open conveyor belt structures such as belt conveyors or chain conveyors are commonly used for conveying stamping waste. While these devices can achieve basic horizontal or inclined conveying functions, they have significant drawbacks in practical applications. The main problem is that during the process of detaching from the mold and falling and being conveyed, the surface and gaps of the stamping waste often adhere to or carry a large amount of fine metal fragments, dust, and impurities such as stamping oil and coolant residue generated by punching and friction. Existing open conveyor belt structures lack effective screening or cleaning mechanisms, making it impossible to effectively intercept and collect these fragments and impurities during the conveying process. The consequences are twofold: firstly, fine metal fragments are easily scattered and dispersed onto the workshop floor and around equipment during the conveying process, seriously polluting the working environment; secondly, if the impurities attached to the waste are not effectively removed, they will directly affect the subsequent packaging, smelting, or reprocessing of the waste, reducing the purity and quality of the recycled material, increasing the difficulty and cost of subsequent processing steps, and even affecting the quality of the recycled metal.

[0004] Based on this, a waste conveying device for sheet metal stamping of automotive parts is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-5 As shown, a conveying device for conveying waste sheet metal stamping of automotive parts includes a screening conveyor belt 11 with a plurality of screen holes. Drive rollers and transmission rollers are respectively fitted at both ends of the screening conveyor belt 11. The rotating shafts at both ends of the drive rollers and transmission rollers are rotatably disposed within rotating holes at the ends of two retaining plates 15. Each retaining plate 15 is fixedly mounted on the upper end of a base frame. A first baffle is fixedly mounted on the upper end of each retaining plate 15. A support frame is fixedly mounted between the upper ends of the two first baffles. A baffle plate 17 is fitted inside the support frame. The baffle plate 17 is fixedly mounted at the output end of an electric cylinder 18. The electric cylinder 18 is fixedly mounted in a mounting hole at the upper end of the support frame. A cleaning mechanism for cleaning the metal slag on the outside of the waste is provided on one side of the baffle plate 17. A screening mechanism for shaking and screening the waste is fitted at one end of the screening conveyor belt 11. The cleaning mechanism facilitates the cleaning of the metal slag on the outside of the waste, and the screening mechanism facilitates the removal of other impurities from the waste.

[0025] Both sides of the screening conveyor belt 11 are fixedly provided with synchronous belts 12, and both ends of the synchronous belts 12 are meshed with synchronous gears 13. Several synchronous gears 13 are respectively fixedly provided on the rotating shafts at both ends of the drive roller and the transmission roller. One end of the rotating shaft of the drive roller is fixedly connected to the output end of the first motor 14. The first motor 14 is fixedly provided on one side of the holding plate 15. In use, when it is necessary to transport waste, the waste is placed on the upper end of the screening conveyor belt 11, and then the first motor 14 is started. The first motor 14 drives the drive roller to rotate, and the rotating shafts at both ends of the drive roller drive the synchronous gears 13 to rotate. The synchronous gears 13 cooperate with the synchronous belts 12 to drive the transmission roller to rotate, and then drive the screening conveyor belt 11 to rotate. The screening conveyor belt 11 moves the waste.

[0026] The cleaning mechanism includes a first cleaning roller 20. First rotating plates are rotatably mounted on rotating shafts at both ends of the first cleaning roller 20. Each first rotating plate is fixedly mounted on one side of a baffle plate 17. The first cleaning roller 20 has a plurality of bristles. A mounting shaft is fitted on the other side of the baffle plate 17. Spiral plates 16 are symmetrically mounted on the mounting shaft. Second rotating plates are rotatably mounted on both ends of the mounting shaft. Each second rotating plate is fixedly mounted on the baffle plate 17. A first driven wheel is fixedly mounted at one end of the mounting shaft. The first driven wheel is connected to a first driving wheel via a first belt. A wheel is fixedly mounted on the output end of a second motor 19, which is fixedly mounted on a fixed frame. Both ends of the fixed frame are fixedly connected to a first rotating plate and a second rotating plate, respectively. A second driven wheel is fixedly mounted on the rotating shaft at the other end of the mounting shaft. The second driven wheel is connected to a second driving wheel via a second belt. The second driving wheel is fixedly mounted on the rotating shaft at one end of a first cleaning roller 20. An acceleration roller 21 is fitted to one side of the first cleaning roller 20. A third rotating plate is rotatably mounted on the rotating shafts at both ends of the acceleration roller 21. The third rotating plate is fixedly mounted on the first rotating plate. One end of the rotating shaft 21 is fixedly connected to the output end of the third motor 22. The third motor 22 is fixedly mounted on one side of the third rotating plate. A control component 35 is fixedly mounted on the support frame. In use, when the waste material is at one end of the screening conveyor belt 11, the control component 35 controls the first motor 14, the second motor 19, and the third motor 22 to start, so that the screening conveyor belt 11 transports the waste material. The output end of the second motor 19 drives the mounting shaft to rotate through the first belt. The mounting shaft drives the spiral plate 16 to rotate. The mounting shaft drives the first cleaning roller 20 to rotate through the second belt, so that the waste material moves to the spiral plate 16. When the waste material is below the spiral plate 16, the spiral plate 16 spreads the waste material to both sides. Then the baffle plate 17 intercepts the stacked waste material. When the waste material moves to the bottom of the first cleaning roller 20, the first cleaning roller 20 cleans the impurities at the top of the waste material with the brush bristles. Then the waste material moves to the bottom of the acceleration roller 21. The acceleration roller 21 is in close contact with the top of the waste material, and the acceleration roller 21 rotates at a different speed than the drive roller. The acceleration roller 21 drives the waste material to move quickly, so that the waste material slides on the upper end of the screening conveyor belt 11. The upper end of the screening conveyor belt 11 is provided with a wear-resistant rough layer, which cleans the impurities at the bottom of the waste material. Then the impurities fall through the screen holes.

[0027] The inner side of the screening conveyor belt 11 is provided with a guide frame 27. The guide frame 27 is set at an obtuse angle and is fixed between two retaining plates 15. The upper end of the retaining plate 15 and the end of the guide frame 27 are provided with a discharge chute. When in use, when impurities fall through the screen holes, they fall onto the upper end of the guide frame 27. Since the guide frame 27 is set at an obtuse angle, the impurities are discharged through the discharge chute.

[0028] The screening mechanism includes a screening plate 28. A second baffle is symmetrically arranged on the upper end of the screening plate 28. One end of the screening plate 28 is located above the screening conveyor belt 11. Sliding strips are symmetrically arranged on the bottom end of the screening plate 28. Guide rods are slidably arranged in the middle of each sliding strip. The guide rods are all fixedly installed inside the mounting box 30. The bottom end of the mounting box 30 is inclined. A slag discharge port is provided on one side of the mounting box 30. Several fixing strips 29 are arrayed on the upper end of the screening plate 28. A connecting block is fixedly installed on one side of the screening plate 28. A connecting rod 31 is hinged to the upper end of the connecting block. A swing rod 32 is hinged to the other end of the connecting rod 31. A connecting column is hinged to the other end of the swing rod 32. The connecting column is fixedly installed on the upper end of the fixing plate. The fixing plate is fixedly installed in the mounting box. The upper end of the swing rod 32 is provided with a limiting groove in the upper end of the mounting groove. A sliding rod is slidably provided in the limiting groove. The sliding rod is fixedly installed on the upper end of the drive plate 33. The bottom rotating shaft of the drive plate 33 is rotatably installed in the upper rotating hole of the fixed plate. The bottom rotating shaft of the drive plate 33 is fixedly connected to the output end of the fifth motor 34. The fifth motor 34 is fixedly installed on the bottom end of the fixed plate. When it is necessary to transport waste, the waste is placed on the upper end of the screening plate 28, and the fifth motor 34 is started at the same time. The output end of the fifth motor 34 drives the drive plate 33 to rotate. The drive plate 33 drives the sliding rod to rotate. The sliding rod slides in the limiting groove, so that the swing rod 32 pushes the screening plate 28 to slide back and forth through the connecting rod 31, so that the screening plate 28 performs preliminary screening of the waste.

[0029] The bottom end of the screening conveyor belt 11 is closely attached to a second cleaning roller 23. The second cleaning roller 23 is rotatably mounted in a rotating hole inside a protective box 25. The protective box 25 is fixedly mounted on a base frame. One end of the rotating shaft of the second cleaning roller 23 is fixedly connected to the output end of a fourth motor 24. The fourth motor 24 is fixedly mounted on one side of the protective box 25. In use, when waste falls from the top of the screening conveyor belt 11, as the screening conveyor belt 11 passes the position of the second cleaning roller 23, the fourth motor 24 drives the second cleaning roller 23 to rotate. The second cleaning roller 23 cleans the impurities attached to the outside of the screening conveyor belt 11 with its bristles.

[0030] The first cleaning roller 20 and the second cleaning roller 23 are both equipped with comb plates 26. The comb plates 26 are fixedly installed between the two first rotating plates and inside the protective box 25. When in use, the comb plates 26 can clean the impurities inside the first cleaning roller 20 and the second cleaning roller 23 when they rotate.

[0031] The above embodiment discloses a waste conveying device for sheet metal stamping of automotive parts. When waste needs to be conveyed, it is placed on the upper end of a screening plate 28. Simultaneously, a fifth motor 34 is started. The output of the fifth motor 34 drives a drive disc 33 to rotate, which in turn drives a sliding rod to rotate. The sliding rod slides within a limiting groove, causing a swing rod 32 to push the screening plate 28 back and forth via a connecting rod 31. This allows the screening plate 28 to perform preliminary screening of the waste. Subsequently, the waste falls onto one end of a screening conveyor belt 11. A control unit 35 starts the first motor 14, the second motor 19, and the third motor 22, causing the screening conveyor belt 11 to convey the waste. The output of the second motor 19 drives a mounting shaft to rotate via a first belt. The mounting shaft drives a spiral plate 16 to rotate, and the mounting shaft drives a first cleaning roller 20 to rotate via a second belt, causing the waste to move to the spiral plate 16. When the waste material is below the spiral plate 16, the spiral plate 16 spreads the waste material to both sides. Then the baffle plate 17 intercepts the stacked waste material. When the waste material moves to the bottom of the first cleaning roller 20, the first cleaning roller 20 cleans the impurities on the upper end of the waste material with its brush bristles. Then the waste material moves to the bottom of the acceleration roller 21. The acceleration roller 21 is in close contact with the upper end of the waste material, and the acceleration roller 21 rotates at a different speed than the drive roller. The acceleration roller 21 drives the waste material to move quickly, so that the waste material slides on the upper end of the screening conveyor belt 11. The upper end of the screening conveyor belt 11 is provided with a wear-resistant rough layer, which cleans the impurities at the bottom end of the waste material. Then the impurities fall through the screen holes. After the waste material falls from the upper end of the screening conveyor belt 11, when the screening conveyor belt 11 passes the position of the second cleaning roller 23, the fourth motor 24 drives the second cleaning roller 23 to rotate. The second cleaning roller 23 cleans the impurities attached to the outside of the screening conveyor belt 11 with its brush bristles.

[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
