Description

Technical Field

[0001] This invention relates to the field of plastic waste crushing and treatment technology, specifically to a plastic product processing and crushing equipment. Background Technology

[0002] Plastics are ubiquitous in our daily lives and have become an important part of our lives. A lot of plastic waste is generated during the production and processing of plastic products. The traditional methods of disposal are: 1. Some places choose artificial landfill, which not only has a long degradation period but also pollutes the land; 2. Some choose artificial incineration, which pollutes the air.

[0003] To address the aforementioned issues, Chinese Patent No. CN223802880U discloses a multifunctional waste plastic crushing device, comprising a crushing box with a conveying trough at the top and a feeding hopper at the top. Support bases are fixedly connected to the bottom of the crushing box on all four sides. A first crushing component and a second crushing component are installed inside the crushing box, and a discharge hopper is located at the bottom. Cleaning components are located on the front and back of the crushing box. The cooperation between the first and second crushing components allows for the crushing of waste plastics for reuse, avoiding the problems associated with traditional processing methods.

[0004] The above-mentioned crushing equipment has the following problems during actual use: after crushing waste plastics, plastic particles are obtained, but the size of the plastic particles varies. The above-mentioned crushing equipment does not have a screening function, that is, it is necessary to manually screen out the plastic particles of the required size for further processing. However, manual screening is not only labor-intensive, but also leads to low work efficiency. Summary of the Invention

[0005] The present invention aims to provide a plastic product processing and crushing equipment to solve the problem that existing crushing equipment does not have a screening function for crushed materials and that manual screening is inefficient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a plastic product processing and crushing equipment, comprising a processing box, a feed inlet and a discharge outlet, a crushing mechanism and a movable plate inside the processing box, the feed inlet of the crushing mechanism being between the movable plate and the movable plate, the movable plate being able to move vertically within the processing box; a plurality of through holes are provided on the movable plate along its length, and a screening plate is provided on the through holes; a plurality of curved plates are provided on the movable plate for guiding particles to the screening plates, the plurality of through holes and the plurality of curved plates being spaced apart along the length of the movable plate; further comprising a driving mechanism for driving the movable plate to reciprocate vertically, and a cleaning mechanism for cleaning the plurality of screening plates.

[0007] The principle and advantages of this scheme are: 1. In this solution, plastic enters the processing box through the feed inlet and is crushed by the crushing mechanism to obtain granules. The granules of qualified size pass through the screening plate and are discharged from the discharge outlet. This allows for the direct production of granules of qualified size without the need for manual screening, reducing the workload of workers and improving work efficiency.

[0008] 2. Some particles pass directly through the screening plate, while others fall onto the curved plate. Guided by the curved plate, they are directed back to the screening plate, facilitating particle screening and discharge.

[0009] 3. The drive mechanism drives the movable plate to move vertically back and forth, which in turn drives the screening plate to move vertically back and forth, thereby achieving vibration of the screening plate and preventing clogging of the screening plate.

[0010] Furthermore, the cleaning mechanism includes several cleaning sections arranged along the length of the movable plate, several through holes and several cleaning sections spaced apart along the length of the movable plate. Each cleaning section includes a chamber opened inside the movable plate and a group of holes arranged on the top of the movable plate. A rotating shaft is rotatably connected inside the chamber and is rotatably connected to the processing box. Several cleaning arms are arranged on the rotating shaft along the axial direction of the rotating shaft. Each cleaning arm is provided with a first bristle layer and is located below the curved plate. The group of holes includes several top holes opened on the top of the movable plate along the width direction of the movable plate. The top holes communicate with the chamber, and the cleaning arms pass through the top holes and can swing within the top holes. The screening plate is located on the movement trajectory of the first bristle layer. It also includes an adjustment section that drives multiple rotating shafts to rotate synchronously with the vertical movement of the movable plate.

[0011] With the above setup, during the vertical reciprocating motion of the movable plate, multiple rotating shafts rotate back and forth. When the rotating shafts rotate counterclockwise, they drive the cleaning arm and the first brush layer to rotate counterclockwise, causing the first brush layer to act on the screening plate, thereby cleaning the screening plate and preventing it from clogging. When the rotating shafts rotate clockwise, they drive the cleaning arm and the first brush layer to rotate clockwise, causing them to return to their initial positions for the next operation.

[0012] Furthermore, the adjustment section includes several side grooves formed on the side wall of the machining box, several racks fixedly connected to the side wall of the machining box, and an adjustment gear coaxially connected to the rotating shaft. The rotating shaft can move and rotate vertically in the side grooves, and the racks mesh with the adjustment gear.

[0013] With the above settings, during the vertical reciprocating motion of the movable plate, the movable plate drives the rotating shaft to reciprocate vertically within the side groove, causing the adjusting gear to mesh with the gear and drive the rotating shaft to rotate back and forth.

[0014] Furthermore, several baffles are provided on the movable plate along its length, and the baffles make frictional contact with the side of the processing box near the side groove.

[0015] With the above settings, during the vertical movement of the movable plate, the movable plate drives the baffle to move synchronously. The baffle can shield the side channel and prevent particulate matter from leaking out.

[0016] Furthermore, an operating box is provided on the side wall of the processing box, and the adjusting gear and rack are both located inside the operating box. The adjusting gear can move vertically inside the operating box.

[0017] With the above setup, the adjusting gear and rack are both located inside the control box, which protects them from damage caused by external objects and extends their service life.

[0018] Furthermore, a worm gear is coaxially connected to the rotating shaft; a round shaft is rotatably connected inside the chamber, and a worm wheel and a cylindrical cam are coaxially connected to the round shaft. The worm wheel meshes with the worm gear, and a curved groove is provided on the cylindrical cam. An auxiliary block is slidably connected inside the curved groove; a guide plate is provided inside the chamber, and the auxiliary block is laterally slidably connected to the guide plate; several guide holes are provided on the top of the movable plate, and the auxiliary block passes through the guide holes, allowing it to reciprocate laterally within the guide holes; a linkage block is provided on the auxiliary block, and several adjusting blocks are provided on the linkage block. A second brush layer is provided at the bottom of the adjusting block. The linkage block and adjusting blocks are located below the curved plate, and the screening plate is located on the movement trajectory of the second brush layer.

[0019] With the above setup, during the reciprocating rotation of the shaft, the shaft drives the worm gear to reciprocate, the worm gear meshes with the worm wheel to drive the round shaft to reciprocate, the round shaft drives the cylindrical cam to reciprocate, and the cylindrical cam drives the linkage block to move laterally through the curved groove and auxiliary block. When the linkage block moves to the left, it drives the adjusting block and the second brush layer to move to the left, so that the second brush layer acts on the screening plate, thereby cleaning the screening plate and preventing it from clogging. When the linkage block moves to the right, it drives the adjusting block and the second brush layer to move to the right, so that the second brush layer returns to its initial position for the next operation.

[0020] Furthermore, the adjusting block is located between two adjacent cleaning arms, and the adjusting block is in frictional contact with the two adjacent cleaning arms.

[0021] With the above configuration, the adjusting block is located between two adjacent cleaning arms. During the lateral reciprocating motion of the adjusting block, the adjusting block comes into frictional contact with the adjacent cleaning arm. Therefore, multiple adjusting blocks and multiple cleaning arms form a barrier, which can block particulate matter.

[0022] Furthermore, the crushing mechanism includes a motor and two crushing shafts rotatably connected to the processing box. The motor is fixedly connected to the processing box, and the output shaft of the motor is coaxially connected to a single crushing shaft. Crushing rollers and crushing gears are coaxially connected to the crushing shafts, and the two crushing gears mesh.

[0023] With the above setup, the motor's output shaft drives a single crushing shaft to rotate, and the two crushing gears mesh to make the two crushing shafts rotate synchronously but in opposite directions, which in turn makes the two crushing rollers rotate synchronously but in opposite directions, thus using the two crushing rollers to crush the plastic.

The inlet 11 is located at the top of the processing box 10, and the outlet 12 is located at the bottom of the processing box 10.

[0027] The processing box 10 is equipped with a crushing mechanism and a movable plate 30. The crushing mechanism is located between the feed inlet 11 and the movable plate 30. The crushing mechanism includes a motor 20 and two crushing shafts rotatably connected to the processing box 10. The motor 20 is fixedly connected to the processing box 10. The output shaft of the motor 20 is coaxially connected to a single crushing shaft. Crushing rollers 21 and crushing gears 22 are coaxially connected on the crushing shafts. The two crushing gears 22 mesh, and the two crushing rollers 21 move in opposite directions. The two crushing rollers 21 are located directly below the feed inlet 11.

[0028] The movable plate 30 can move vertically within the processing box 10. Several through holes 31 are formed along the length of the movable plate 30, and a sieve plate 32 is fixedly connected to each through hole 31. Several curved plates 33 for guiding particles to the sieve plate 32 are fixedly connected to the movable plate 30. The through holes 31 and curved plates 33 are spaced apart along the length of the movable plate 30. Each curved plate 33 includes a vertical section 331 and an inclined section 332 fixedly connected to the vertical section 331. The vertical section 331 is fixedly connected to the movable plate 30, and the left end of the inclined section 332 is lower than its right end.

[0029] It also includes a drive mechanism for driving the movable plate 30 to move vertically and reciprocally. The drive mechanism is a cylinder 34. The cylinder 34 has two outputs. The cylinder 34 is fixedly connected inside the processing box 10. The output shaft of the cylinder 34 is fixedly connected to the movable plate 30.

[0030] It also includes a cleaning mechanism for cleaning multiple screening plates 32. The cleaning mechanism includes several cleaning parts arranged along the length of the movable plate 30, several through holes 31 and several cleaning parts spaced apart along the length of the movable plate 30. The cleaning parts include a chamber 40 opened inside the movable plate 30 and a group of holes arranged on the top of the movable plate 30. A rotating shaft 41 is rotatably connected inside the chamber 40 and is rotatably connected to the processing box 10. Several cleaning arms 42 are fixedly connected to the rotating shaft 41 along the axial direction of the rotating shaft 41. A first bristle layer 43 is fixedly connected to the cleaning arms 42. The cleaning arms 42 are located below the curved plate 33. The cleaning arms 42 do not act on the curved plate 33 during reciprocating rotation, that is, the curved plate 33 will not... The movement of the cleaning arm 42 is affected; the hole group includes a number of top holes 44 opened on the top of the movable plate 30 along the width direction of the movable plate 30. The top holes 44 communicate with the chamber 40. The cleaning arm 42 passes through the top holes 44 and can swing left and right in the top holes 44. The screening plate 32 is located on the movement trajectory of the first brush layer 43. It also includes an adjustment part that drives multiple rotating shafts 41 to rotate synchronously with the vertical movement of the movable plate 30. The adjustment part includes a number of side grooves 45 opened on the rear side wall of the processing box 10, a number of racks 46 fixed to the rear side wall of the processing box 10, and an adjustment gear 47 coaxially connected to the rotating shaft 41. The rotating shaft 41 can move and rotate vertically in the side grooves 45, and the racks 46 mesh with the adjustment gear 47.

[0031] Several baffles 48 are fixedly connected to the movable plate 30 along its length. The baffles 48 are in frictional contact with the side of the processing box 10 near the side groove 45, that is, the baffles 48 are in frictional contact with the rear inner wall of the processing box 10. During the vertical movement of the movable plate 30, the movable plate 30 drives the baffles 48 to move synchronously. The baffles 48 can block the side groove 45 and prevent the leakage of particles. An operating box 49 with a top opening is fixedly connected to the rear side wall of the processing box 10. The adjusting gear 47 and the rack 46 are both located inside the operating box 49. The adjusting gear 47 can move vertically inside the operating box 49.

[0032] A worm gear 50 is coaxially connected to the rotating shaft 41; a round shaft 51 is rotatably connected inside the chamber 40, and a worm wheel 52 and a cylindrical cam 53 are coaxially connected to the round shaft 51. The worm wheel 52 meshes with the worm gear 50. A curved groove is opened on the cylindrical cam 53, and an auxiliary block 54 is slidably connected in the curved groove; a guide plate 55 is fixedly connected inside the chamber 40, and the auxiliary block 54 is laterally slidably connected to the guide plate 55; the top of the movable plate 30 has several guide holes 56, and several through holes 31 and several through holes 31 are opened along the length direction of the movable plate 30. The guide holes 56 are spaced apart, and the auxiliary block 54 passes through the guide holes 56, allowing it to reciprocate laterally within the guide holes 56. A linkage block 57 is fixedly connected to the auxiliary block 54, and several adjusting blocks 58 are fixedly connected to the linkage block 57. A second bristle layer 59 is fixedly connected to the bottom of the adjusting block 58, and the screening plate 32 is located on the movement trajectory of the second bristle layer 59. The linkage block 57 and adjusting blocks 58 are located below the curved plate 33, meaning the curved plate 33 does not affect the movement of the linkage block 57 and adjusting blocks 58. The adjusting block 58 is located between two adjacent cleaning arms 42, and it makes frictional contact with the two adjacent cleaning arms 42.

[0033] The specific implementation process is as follows: When in use, start the motor 20. The output shaft of the motor 20 drives the single crushing shaft to rotate. The two crushing gears 22 mesh to make the two crushing shafts rotate synchronously and in opposite directions, which in turn makes the two crushing rollers 21 rotate synchronously and in opposite directions.

[0034] Plastic is fed into the processing box 10 through the feed inlet 11, and the plastic is crushed by two crushing rollers 21 to obtain granules. The granules of qualified size pass through the screening plate 32 and are discharged from the discharge port 12. In this way, qualified granules can be obtained directly without manual screening, which reduces the workload of workers and improves work efficiency. Furthermore, if the granules fall onto the curved plate 33, they can be guided to the screening plate 32 by the curved plate 33.

[0035] To prevent clogging of the screening plate 32, the following measures can be taken: When the cylinder 34 is started, the output shaft of the cylinder 34 drives the movable plate 30 to move vertically back and forth, which in turn drives the screening plate 32 to move vertically back and forth, thereby achieving the vibration of the screening plate 32 and preventing the screening plate 32 from clogging.

[0036] During the vertical reciprocating motion of the movable plate 30, the movable plate 30 drives the rotating shaft 41 to reciprocate vertically within the side groove 45, causing the adjusting gear 47 to mesh with the gear and drive the rotating shaft 41 to rotate back and forth. When the rotating shaft 41 rotates counterclockwise, it drives the cleaning arm 42 and the first bristle layer 43 to rotate counterclockwise, so that the first bristle layer 43 acts on the screening plate 32, thereby cleaning the screening plate 32 and preventing it from clogging. When the rotating shaft 41 rotates clockwise, it drives the cleaning arm 42 and the first bristle layer 43 to rotate clockwise, so that the cleaning arm 42 and the first bristle layer 43 return to their initial positions for the next operation.

[0037] During the reciprocating rotation of the rotating shaft 41, the rotating shaft 41 drives the worm gear 50 to reciprocate. The worm gear 50 meshes with the worm wheel 52, driving the round shaft 51 to reciprocate. The round shaft 51 drives the cylindrical cam 53 to reciprocate. The cylindrical cam 53 drives the linkage block 57 to move laterally through the curved groove and the auxiliary block 54. When the linkage block 57 moves to the left, it drives the adjusting block 58 and the second brush layer 59 to move to the left, so that the second brush layer 59 acts on the screening plate 32, thereby cleaning the screening plate 32 and preventing the screening plate 32 from clogging. When the linkage block 57 moves to the right, it drives the adjusting block 58 and the second brush layer 59 to move to the right, so that the second brush layer 59 returns to its initial position for the next operation.

[0038] The adjusting block 58 is located between two adjacent cleaning arms 42. During the lateral reciprocating motion of the adjusting block 58, the adjusting block 58 comes into frictional contact with the adjacent cleaning arm 42. Therefore, the multiple adjusting blocks 58 and multiple cleaning arms 42 form a barrier, which can block particulate matter.

[0039] Several discharge ports are opened on the front side wall of the processing box 10. The discharge ports are located above the movable plate 30, and sealing blocks 60 are threadedly connected to the discharge ports. Particles that do not meet the size requirements will remain on the surface of the movable plate 30. After removing the sealing block 60, the particles that do not meet the size requirements can be discharged for further crushing.
