[0002] The automotive parts industry provides components for the entire vehicle manufacturing industry, forming the foundation of the automotive industry and a crucial component of the automotive supply chain. A car generally consists of four parts: engine, chassis, body, and electrical components, from which various sub-products within the auto parts industry are derived. Based on the raw materials used, auto parts can be categorized as metal, plastic, and electronic.

[0003] The production of automotive parts involves the recycling and reprocessing of plastic parts. Typically, after being collected and sorted, plastic parts require cleaning and crushing. Currently, existing automotive parts recycling equipment begins by crushing the plastic parts. After crushing, the plastic debris must be screened and graded for subsequent processing. However, existing recycling equipment is not convenient for pre-processing plastic parts during crushing. Large pieces of plastic can easily cause the crushing rollers to become stuck, resulting in poor crushing results. In severe cases, the equipment can be damaged, reducing the effectiveness and efficiency of the recycling process. Summary of the Invention

[0004] The present invention proposes a recycling and processing device for automobile parts processing, which solves the problem that existing recycling equipment in the relevant technology is not convenient for pre-processing plastic accessories, and easily causes the crushing roller to be affected by large pieces of plastic and become stuck, resulting in poor crushing effect and reduced recycling processing effect and efficiency.

[0005] The technical solution of the present invention is as follows: A recycling and processing device for processing automobile parts, comprising: a main body cylinder, a feed box fixedly mounted on one side of the top of the main body cylinder, guide plates symmetrically fixedly mounted on both sides of the inner wall of the feed box, a crushing mechanism disposed within the feed box, notches formed on both sides of the feed box above the crushing mechanism, and isolation mechanisms disposed within the notches for separating large pieces of material;

[0007] Both sides of the feed box are rotatably connected to incomplete gears, and two sets of racks are fixedly installed on the two movable blocks in an upper and lower symmetrical manner, and each set of racks is meshed with an incomplete gear;

[0008] On one side of the feeding box, a double-shaft motor is fixedly installed, and a first synchronous pulley transmission group is connected between the output ends of the double-shaft motor and two incomplete gears;

[0009] A screening mechanism for screening the crushed materials is arranged in the main cylinder, and a stirring mechanism for cooperating with the screening mechanism to turn the materials is also arranged in the main cylinder.

[0010] Preferably, the isolation mechanism includes a plurality of fixed rods fixedly installed in the notch, a grille plate slidably connected to the surface of the fixed rods, a second spring sleeved on the surface of the fixed rods and connected to the inner bottom wall of the notch and the grille plate at both ends respectively, connecting plates fixedly installed on both side surfaces of the grille plate, and a roller rotatably connected to the bottom of the movable block and in contact with the connecting plate. One end of the connecting plate has a triangular convex block at the top.

[0011] Through the above technical solution, after the plastic fittings enter the feeding box, small pieces of plastic can fall through the grille plate, while large pieces of plastic remain on the grille plate. During the movement of the movable block, through the cooperation of the roller and the connecting plate and the second spring, the vibration effect of the grille plate can be achieved, which is convenient for preventing the plastic blocks from being blocked on the grille plate.

[0012] Preferably, the crushing mechanism includes two crushing rollers symmetrically and rotatably connected inside the feeding box with one end extending outside the feeding box, two first spur gears fixedly connected to one end of the two crushing rollers and meshing with each other, and a single-shaft motor I fixedly installed on one side surface of the feeding box. The output end of the single-shaft motor I is connected to one of the first spur gears.

[0013] Through the above technical solution, the single-shaft motor I drives one of the first spur gears and the crushing roller to rotate, and under the action of the meshing of the two first spur gears, the other crushing roller is driven to rotate relatively, so that the crushing roller can further crush the plastic blocks, which is convenient for improving the crushing effect.

[0014] Preferably, the screening mechanism includes an annular shell fixedly installed in the main cylinder, an annular frame arranged in the annular shell, a screening cylinder rotatably connected in the annular frame, and a transmission component arranged in the main cylinder for rotating the screening cylinder.

[0015] Through the above technical solution, the crushed plastic falls into the screening cylinder, and through the cooperation of the stirring mechanism and the transmission component, the screening cylinder can be rotated for screening.

[0016] Preferably, the transmission component includes a toothed ring fixedly installed on the top surface of the screening cylinder, a rotating shaft rod rotatably connected to the inner top wall of the main cylinder, a second spur gear fixedly connected to the bottom end of the rotating shaft rod and meshing with the toothed ring, and a second synchronous pulley transmission group arranged between the rotating shaft rod and the stirring mechanism for rotating the rotating shaft rod.

[0017] Through the above technical solution, when the stirring mechanism rotates, the rotating shaft rod and the second straight gear are driven by the second synchronous pulley transmission group, so that the screening cylinder is driven to rotate through the toothed ring for screening.

[0018] Preferably, the stirring mechanism includes a lifting member provided in the main body cylinder, a spline shaft provided on the lifting member, a spline sleeve slidably sleeved on the surface of the spline shaft, a plurality of turning paddles fixedly installed on the bottom surface of the spline sleeve, and a plurality of stirring blades fixedly installed on the surface of the spline sleeve and above the turning paddles.

[0019] Through the above technical solution, the spline shaft and the spline sleeve are driven to rotate by the lifting member, so that the spline sleeve drives the stirring blades and the turning paddles to stir and turn the material.

[0020] Preferably, the lifting member includes a single-shaft motor two fixedly installed at the top of the main body cylinder and whose output end movably passes through the main body cylinder, a reciprocating lead screw fixedly connected to the output end of the single-shaft motor two, a moving block threadedly connected to the surface of the reciprocating lead screw and slidably connected to the rotating shaft rod, a rotating ring rotatably connected to the top surface of the spline sleeve, and a fixing block fixedly connected between the rotating ring and the moving block. The second synchronous pulley transmission group is connected between the reciprocating lead screw and the rotating shaft rod.

[0021] Through the above technical solution, the reciprocating lead screw is driven to rotate by the single-shaft motor two, and the moving block is driven to move up and down reciprocally. At the same time, the spline sleeve is driven to slide up and down by cooperating with the fixing block and the rotating ring, so that the stirring blades and the turning paddles move up and down, which is convenient for stirring the materials at different heights inside the screening cylinder.

[0022] Preferably, a plurality of hollow fixing seats are fixedly installed on the inner bottom wall of the annular shell. A third spring is fixedly connected between the fixing seat and the annular frame. An energy-saving mechanism for reducing energy consumption is provided in the fixing seat, and the energy-saving mechanism is electrically connected to the stirring mechanism.

[0023] Preferably, the energy-saving mechanism includes a plurality of first trapezoidal blocks fixedly installed at the bottom of the annular frame, a sliding rheostat fixedly installed in the fixing seat, a connecting rod installed on the sliding piece of the sliding rheostat and slidably connected to the fixing seat, a second trapezoidal block fixedly connected to one end of the connecting rod and adapted to the first trapezoidal block, and a fourth spring sleeved on the surface of the connecting rod and connected to the fixing seat and the second trapezoidal block at both ends respectively.

[0024] Through the above technical solution, the first trapezoidal block is driven to move by the annular frame, and the connecting rod is driven to move by cooperating with the second trapezoidal block, so that the sliding piece of the sliding rheostat slides, which can increase the output kinetic energy of the single-shaft motor two and is convenient for improving the stirring effect of the stirring mechanism on the materials inside the screening cylinder.

[0025] Preferably, a discharge pipe is fixedly installed at the bottom of the screening cylinder, a valve is arranged on the surface of the discharge pipe, and an annular collecting shell is threadedly connected to the bottom of the main cylinder.

[0026] Through the above technical solution, it is convenient to discharge the plastic materials in the screening cylinder through the discharge pipe, and it is convenient to collect the screened scraps through the annular collecting shell.

[0027] The working principle and beneficial effects of the present invention are as follows:

[0028] First, after the plastic fittings enter the feed box, the separation mechanism separates the plastic fittings of different sizes. At the same time, the double-shaft motor drives the incomplete gear to rotate through the synchronous pulley transmission group I, so that the incomplete gear continuously meshes with the rack, and drives the movable block to move relatively away from the tension spring I through the rack, so that the extrusion crushing block moves relatively away. When the incomplete gear does not mesh with the rack, the spring I drives the movable block and the extrusion crushing block to move relatively closer, so that the extrusion crushing block extrudes and crushes the large plastic fittings during the movement. Therefore, the effect of preliminary crushing pretreatment of the plastic fittings is realized, avoiding the situation of material jamming, ensuring the crushing effect of the subsequent crushing mechanism, reducing the risk of equipment damage, and effectively improving the effect and efficiency of parts recycling and processing.

[0029] Second, when the present invention is screening in the screening cylinder, the single-shaft motor II drives the reciprocating lead screw to rotate, and drives the spline shaft and the spline sleeve to rotate through the reciprocating lead screw, so that the stirring blades and the turning paddles stir and turn the plastic. At the same time, the reciprocating lead screw drives the rotating shaft rod to rotate through the synchronous pulley transmission group II, so that the straight gear II meshes with the toothed ring to drive the screening cylinder to rotate and screen. When the reciprocating lead screw rotates, it drives the moving block to reciprocate up and down, and drives the spline sleeve to slide up and down through the fixed block and the rotating ring, so that the stirring blades and the turning paddles move up and down, achieving the effect that the stirring blades and the turning paddles can rotate and stir while also moving up and down to adjust the position, facilitating the stirring treatment of the materials at different heights inside the screening cylinder and improving the stirring effect.

[0030] Third, when the plastic falls into the screening cylinder, the screening cylinder and the annular frame move downward under the action of gravity, compressing the spring III. At the same time, the trapezoidal block I moves, so that the trapezoidal block I pushes the trapezoidal block II to move, so that the trapezoidal block II pushes the connecting rod to move and compresses the spring IV. The connecting rod drives the sliding piece of the sliding rheostat to slide, prompting the output kinetic energy of the single-shaft motor II to increase. When the plastic becomes less, affected by the spring III and gravity, the screening cylinder moves upward, and at the same time drives the sliding piece of the sliding rheostat to slide reversely to reduce the sliding distance through the spring IV, so that the output kinetic energy of the single-shaft motor II decreases, facilitating the effective reduction of the consumption of dynamic energy and electric energy, and thus achieving the energy-saving effect.

Specific embodiments

[0043] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] Example 1

[0045] See also Figures 1 to 10 The present invention provides a recycling device for automobile parts processing, comprising: a main body cylinder 1, a feed box 2 fixedly mounted on one side of the top of the main body cylinder 1, guide plates 3 symmetrically fixedly mounted on both sides of the inner wall of the feed box 2, a crushing mechanism provided in the feed box 2, notches provided on both sides of the feed box 2 and above the crushing mechanism, and an isolation mechanism provided in the notches for separating large pieces of material;

[0046] Both sides of the feed box 2 are connected with a T-shaped movable block 4 in a sliding manner, one end of the movable block 4 is fixedly connected with an extrusion and crushing block 5, and one side of the movable block 4 is fixedly installed with a spring 6 connected to the feed box 2;

[0047] Both sides of the feed box 2 are rotatably connected with an incomplete gear 7, and two sets of racks 8 are fixedly installed on the two movable blocks 4 in an upper and lower symmetrical manner, and each set of racks 8 is meshed with an incomplete gear 7;

[0048] A dual-shaft motor 9 is fixedly installed on one side of the feed box 2, and a synchronous wheel transmission group 10 is connected between the output end of the dual-shaft motor 9 and the two incomplete gears 7.

[0049] The technical solution provided by this embodiment is as follows: During use, plastic fittings are poured into the feeding box 2, and the plastic fittings are guided into the space between two extrusion and crushing blocks 5 through the guiding plate 3. At the same time, the plastic fittings of different sizes are separated by the separating mechanism, so that the smaller plastic fittings fall and are directly crushed by the crushing mechanism, while the larger plastic fittings remain above the separating mechanism. At this time, the double-shaft motor 9 drives the first synchronous pulley transmission group 10 to rotate, and the first synchronous pulley transmission group 10 drives the incomplete gears 7 on both sides to rotate. During the rotation of the incomplete gears 7, they can continuously engage with the upper and lower racks 8, and drive the racks 8 to move relatively away from each other. At the same time, the racks 8 drive the two movable blocks 4 to move relatively away from each other, and stretch the first spring 6. Thus, the movable blocks 4 drive the extrusion and crushing blocks 5 to move relatively away from each other. When the incomplete gears 7 are not engaged with the racks 8, the first spring 6 can drive the movable blocks 4 to reset and make the extrusion and crushing blocks 5 move relatively closer to each other. By cycling like this, the extrusion and crushing blocks 5 can extrude and crush the large plastic fittings during the process of moving closer to and away from each other. Therefore, the effect of preliminary crushing pretreatment of plastic fittings is achieved, avoiding the situation of material jamming that is easily affected by large plastic fittings when the crushing mechanism directly crushes, ensuring the crushing effect of the subsequent crushing mechanism, reducing the risk of equipment damage, and effectively improving the effect and efficiency of parts recycling and processing.

[0050] Further, the isolation mechanism includes a plurality of fixed rods 11 fixedly installed in the notch, a grille plate 12 slidably connected to the surface of the fixed rods 11, a second spring 13 sleeved on the surface of the fixed rods 11 and connected to the inner bottom wall of the notch and the grille plate 12 at both ends respectively, connecting plates 14 fixedly installed on both side surfaces of the grille plate 12, and a roller 15 rotatably connected to the bottom of the movable block 4 and in contact with the connecting plates 14. One end of the connecting plate 14 has a triangular protrusion at the top.

[0051] Specifically, when the plastic fittings enter the feeding box 2, the small plastic fittings can pass through the grille plate 12 and fall to be directly crushed by the crushing mechanism, while the large plastic fittings remain on the grille plate 12, so that the movable block 4 drives the extrusion and crushing blocks 5 to move for preliminary crushing treatment. When the movable block 4 moves, it can drive the roller 15 to roll on the connecting plate 14. When the roller 15 contacts the protrusion on the connecting plate 14, it can push the connecting plate 14 to move downward. At the same time, the connecting plate 14 drives the grille plate 12 to move downward along the surface of the fixed rod 11, and compresses the second spring 13 through the grille plate 12. After the roller 15 and the protrusion are separated, the grille plate 12 can be driven to reset under the action of the second spring 13. By cycling like this, the effect of vibrating the grille plate 12 can be achieved, which is convenient for preventing the plastic blocks from being blocked on the grille plate 12, and effectively improves the efficiency and effect of plastic falling.

[0052] Furthermore, the crushing mechanism includes two crushing rollers 16 symmetrically and rotatably connected inside the feeding box 2 with one end extending outside the feeding box 2, two first straight gears 17 fixedly connected to one end of the two crushing rollers 16 and meshing with each other, and a single-shaft motor 18 fixedly installed on one side of the feeding box 2. The output end of the single-shaft motor 18 is connected to one of the first straight gears 17.

[0053] Specifically, after the larger plastic materials are crushed into small pieces and pass through the grille plate 12, the plastic pieces fall onto the two crushing rollers 16. At this time, the single-shaft motor 18 drives one of the first straight gears 17 and the crushing roller 16 to rotate. Under the action of the two first straight gears 17 meshing with each other, the other crushing roller 16 is driven to rotate relatively, so that the crushing rollers 16 can further crush the plastic pieces, which is convenient for improving the crushing effect.

[0054] Embodiment 2

[0055] Based on Embodiment 1, the recycling and treatment device for automobile parts provided by the present invention is further optimized. In this embodiment: a screening mechanism for screening the crushed materials is provided inside the main body cylinder 1, and a stirring mechanism for cooperating with the screening mechanism to turn over the materials is also provided inside the main body cylinder 1.

[0056] The technical solution provided in this embodiment is: by providing a screening mechanism, it is convenient to screen and classify the crushed plastics. By providing a stirring mechanism, it is convenient to cooperate with the screening mechanism to stir the plastics, which is beneficial to improving the screening effect.

[0057] Furthermore, the screening mechanism includes an annular shell 19 fixedly installed inside the main body cylinder 1, an annular frame 20 arranged inside the annular shell 19, a screening cylinder 21 rotatably connected inside the annular frame 20, and a transmission component arranged inside the main body cylinder 1 for rotating the screening cylinder 21.

[0058] The transmission component includes a toothed ring 22 fixedly installed on the top surface of the screening cylinder 21, a rotating shaft rod 23 rotatably connected to the inner top wall of the main body cylinder 1, a second straight gear 24 fixedly connected to the bottom end of the rotating shaft rod 23 and meshing with the toothed ring 22, and a second synchronous pulley transmission group 34 arranged between the rotating shaft rod 23 and the stirring mechanism for rotating the rotating shaft rod 23.

[0059] Specifically, when the material falls into the screening cylinder 21 after being crushed, the stirring mechanism is started to stir the material in the screening cylinder 21. At the same time, under the action of the synchronous pulley transmission group two 34, the rotating shaft rod 23 drives the second straight gear 24 to rotate synchronously, and the second straight gear 24 meshes with the toothed ring 22 to drive the screening cylinder 21 to rotate reversely relative to the stirring mechanism in the annular frame 20. Thus, while the material is being stirred, under the action of centrifugal force, the crushed slag and impurities in the material can be screened and discharged, so as to achieve the function of screening and grading plastic materials and facilitate the subsequent treatment of smaller plastic crushed slag.

[0060] Further, the stirring mechanism includes a lifting component arranged in the main body cylinder 1, a spline shaft 25 arranged on the lifting component, a spline sleeve 26 slidably sleeved on the surface of the spline shaft 25, a plurality of turning paddles 27 fixedly installed on the bottom surface of the spline sleeve 26, and a plurality of stirring blades 28 fixedly installed on the surface of the spline sleeve 26 and above the turning paddles 27.

[0061] The lifting component includes a single-shaft motor two 29 fixedly installed at the top of the main body cylinder 1 and whose output end movably passes through the main body cylinder 1, a reciprocating lead screw 30 fixedly connected to the output end of the single-shaft motor two 29, a moving block 31 threadedly connected to the surface of the reciprocating lead screw 30 and slidably connected to the rotating shaft rod 23, a rotating ring 32 rotatably connected to the top surface of the spline sleeve 26, and a fixing block 33 fixedly connected between the rotating ring 32 and the moving block 31. The synchronous pulley transmission group two 34 is connected between the reciprocating lead screw 30 and the rotating shaft rod 23.

[0062] Specifically, when the material enters the screening cylinder 21 for screening, the single-shaft motor two 29 drives the reciprocating lead screw 30 to rotate, and the reciprocating lead screw 30 drives the spline shaft 25 to rotate, so that the spline shaft 25 drives the spline sleeve 26 to rotate, and further the spline sleeve 26 drives the stirring blades 28 and the turning paddles 27 to rotate synchronously to stir and turn over the material falling into the screening cylinder 21. At the same time, the reciprocating lead screw 30 cooperates with the synchronous pulley transmission group two 34 to drive the rotating shaft rod 23 to rotate, and the second straight gear 24 meshes with the toothed ring 22 to make the screening cylinder 21 rotate synchronously for screening, which is beneficial to fully screen out the crushed slag; during the rotation of the reciprocating lead screw 30, it can drive the moving block 31 to reciprocate up and down along the surface of the rotating shaft rod 23, and drive the rotating ring 32 to reciprocate through the fixing block 33, and drive the spline sleeve 26 to slide up and down along the surface of the spline shaft 25 through the rotating ring 32, so that the stirring blades 28 and the turning paddles 27 move up and down, achieving the effect that the stirring blades 28 and the turning paddles 27 can rotate and stir while also moving up and down to adjust the position, facilitating the stirring of materials at different heights inside the screening cylinder 21 and improving the stirring effect.

[0063] Furthermore, a discharge pipe 42 is fixedly installed at the bottom of the screening cylinder 21. A valve is provided on the surface of the discharge pipe 42. The bottom of the main cylinder 1 is threadedly connected with an annular collection shell 43.

[0064] Specifically, by setting the discharge pipe 42, the plastic materials in the screening cylinder 21 can be discharged after the screening is completed. When the screening cylinder 21 rotates for screening, the screened debris can fall along the inner wall of the main cylinder 1 and drop into the annular collection shell 43 for collection. By rotating the annular collection shell 43, it is convenient to disassemble the annular collection shell 43 to process the debris collected therein.

[0065] Embodiment Three

[0066] Based on Embodiment One or Embodiment Two, a recycling and processing device for automobile parts provided by the present invention is further optimized. In this embodiment: A plurality of hollow fixed seats 35 are fixedly installed on the inner bottom wall of the annular shell 19. A third spring 36 is fixedly connected between the fixed seat 35 and the annular frame 20. An energy-saving mechanism for reducing energy consumption is provided in the fixed seat 35. Among them, the energy-saving mechanism is electrically connected to the drive source in the stirring mechanism.

[0067] The energy-saving mechanism includes a plurality of first trapezoidal blocks 37 fixedly installed at the bottom of the annular frame 20, a sliding rheostat 38 fixedly installed in the fixed seat 35, a connecting rod 39 installed on the sliding piece of the sliding rheostat 38 and slidably connected to the fixed seat 35, a second trapezoidal block 40 fixedly connected to one end of the connecting rod 39 and adapted to the first trapezoidal block 37, and a fourth spring 41 sleeved on the surface of the connecting rod 39 and connected to the fixed seat 35 and the second trapezoidal block 40 at both ends respectively.

[0068] The technical solution provided by this embodiment is as follows: When the plastic material falls into the screening cylinder 21 after being crushed, the weight of the material itself drives the screening cylinder 21 and the annular frame 20 to move downward, and the annular frame 20 compresses the third spring 36. At the same time, the annular frame 20 drives the first trapezoidal block 37 to move, so that the first trapezoidal block 37 contacts the inclined surface of the second trapezoidal block 40 with its inclined surface and pushes the second trapezoidal block 40 to move, thereby enabling the second trapezoidal block 40 to push the connecting rod 39 to move and compress the fourth spring 41. The connecting rod 39 drives the sliding piece of the sliding rheostat 38 to slide during the movement; since the sliding distance of the sliding rheostat 38 is inversely proportional to the resistance value inside it, and the resistance value is inversely proportional to the current magnitude, the sliding distance of the sliding rheostat 38 is directly proportional to the current magnitude. Moreover, the sliding rheostat 38 is electrically connected to the single-axis motor two 29. Therefore, when the screening cylinder 21 moves downward and the sliding rheostat 38 slides, the output kinetic energy of the single-axis motor two 29 can be increased synchronously, which is convenient for improving the agitation effect of the stirring mechanism on the material inside the screening cylinder 21; when the amount of material inside the screening cylinder 21 decreases after screening out the slag, its own weight also becomes smaller. At this time, affected by the third spring 36 and the self-gravity of the screening cylinder 21, the screening cylinder 21 moves upward, and at the same time, the fourth spring 41 drives the sliding piece of the sliding rheostat 38 to slide in the reverse direction to reduce the sliding distance, so that the output kinetic energy of the single-axis motor two 29 can also be reduced synchronously, which is convenient for effectively reducing the consumption of kinetic energy and electric energy, thereby achieving the effect of energy saving.

[0069] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
