Description

Technical Field

[0001] This application relates to the field of film cutting waste collection, and in particular to a film cutting waste collection mechanism. Background Technology

[0002] During use, films need to be cut to meet different size and shape requirements so that they can be applied in various fields. Waste is generated during the film cutting process. This waste mainly includes burrs generated during slitting, leftover edge scraps after die cutting, waste from miscutting due to insufficient equipment precision or improper debugging, and cut-off portions at film joints. Therefore, waste needs to be collected by a special collection mechanism or device during film cutting to ensure the normal operation of film cutting.

[0003] The existing publication number CN221872786U discloses a film cutting waste collection device, but it still has the following shortcomings in practical use:

[0004] The device directly crushes waste after collection, resulting in waste of different sizes or mixed with impurities being pulverized into indiscriminate particles. This makes it difficult to design recycling processes tailored to the characteristics of different wastes, and consequently, the performance of recycled materials is affected by impurities or uneven morphology, thus reducing the market value of recycled products. Utility Model Content

[0005] In order to improve the problem that the direct crushing of waste materials after collection leads to the loss of the recycling process for films of different sizes, this application provides a film cutting waste collection mechanism.

[0006] The film cutting waste collection mechanism provided in this application adopts the following technical solution:

[0007] A film cutting waste collection mechanism includes a cutting machine body, a guide plate is provided on one side of the surface of the cutting machine body, baffles for guiding waste discharge are fixed on both sides of the surface of the guide plate, and a sorting mechanism for classifying waste is provided on the side of the guide plate away from the cutting machine body.

[0008] The sorting mechanism includes a sorting box fixed on the side of the guide plate away from the surface of the cutting machine body. The sorting box is equipped with a filter plate for sorting waste. The surface of the filter plate has filter holes. A drive plate for driving the filter plate to flip is provided on the side of the filter plate close to the cutting machine body. An abutment strip is fixed on the side of the filter plate away from the cutting machine body. A guide plate for discharging sorted waste is fixed on the inner wall of the sorting box. The guide plate is in an inclined state.

[0009] By adopting the above technical solution, the filter plate sorts the waste by size, and the drive plate drives the filter plate to flip, so that the large-sized waste on the surface of the filter plate is automatically discharged from the surface of the filter plate, and the small-sized waste is discharged from the inside of the sorting box by the guide plate, thereby realizing the automatic sorting and collection of large and small-sized film waste.

[0010] Preferably, the sorting mechanism further includes a drive box fixed to one side of the surface of the sorting box. A micro motor is fixed inside the drive box, and a worm gear rotatably disposed inside the drive box is fixed at the output end of the micro motor. A worm wheel meshing with the worm gear is rotatably disposed inside the drive box, and a transmission shaft rotatably disposed on the side of the sorting box near the drive box surface is fixed at one end of the worm wheel near the drive plate.

[0011] By adopting the above technical solution, the micro motor provides power to the worm gear, which drives the worm gear to rotate, the worm gear drives the worm wheel to rotate, the worm wheel drives the transmission shaft to rotate, the transmission shaft drives the drive plate to rotate, and thus the drive plate drives the filter plate to rotate, thereby realizing the flipping of the filter plate.

[0012] Preferably, a limiting plate for limiting the position of the drive shaft is fixed on the surface of the drive shaft, and a limiting groove for the rotation of the limiting plate is opened on the side of the sorting box near the drive box. A micro switch electrically connected to the micro motor is fixed inside the limiting groove.

[0013] By adopting the above technical solution, the rotation of the drive shaft provides power to the limit plate, causing the limit plate to rotate. When the limit plate rotates to the point where it presses the micro switch contact, the micro switch controls the micro motor to shut down, thereby stopping the drive shaft from rotating and thus controlling the rotation angle of the drive shaft.

[0014] Preferably, a positioning plate is fixedly provided on the side of the filter plate near the drive plate and inserted into the side of the drive plate surface. A positioning block for positioning the positioning plate is symmetrically slidably arranged inside the drive plate. Positioning grooves that are adapted to the positioning blocks are opened on both sides of the surface of the positioning plate. A guide block that is symmetrically fixed and slidably arranged inside the drive plate is provided on the side of the positioning block away from the positioning plate. A spring fixedly arranged inside the drive plate is provided on the side of the positioning block away from the positioning plate surface.

[0015] By adopting the above technical solution, the positioning plate is inserted into one side of the drive plate surface. When the positioning plate enters one side of the drive plate surface, it presses the positioning block, causing the positioning block to retract into the drive plate. The positioning block presses the spring, causing the spring to deform. When the positioning grooves on both sides of the positioning plate surface move to be directly opposite the positioning block, the positioning block loses the pressing force from the positioning plate, and the spring loses the pressing force from the positioning block. Thus, the positioning block is ejected into the positioning groove by the spring's rebound force, fixing the positioning plate to one side of the drive plate surface, thereby installing the filter plate inside the sorting box.

[0016] Preferably, the sorting box has a first collection port for discharging large-sized waste on the side away from the guide plate. The inner wall of the first collection port is fixed with a collection plate, which is inclined. The side of the collection plate near the filter plate has an abutment groove that matches the abutment strip.

[0017] By adopting the above technical solution, after the filter plate is flipped over, it is connected to the collection plate, so that the inclined surface of the filter plate after flipping over is spliced ​​together with the inclined surface of the collection plate. The inclined surface of the filter plate is extended, so that the waste can be discharged into the interior of the sorting box through the abutment groove after the filter plate is tilted, thus completing the collection of large-sized waste and finished products.

[0018] Preferably, a second collection box for collecting large-sized waste and finished products is fixedly provided on one side of the surface of the sorting box near the first collection port. A door is hinged to one side of the surface of the second collection box. An ejection component for ejecting waste is provided inside the second collection box. A third collection box for collecting ejected waste is provided below the surface of the second collection box near the door.

[0019] By adopting the above technical solution, large-sized waste and finished products are discharged into the interior of the second collection box through the first collection port. After the finished products are picked out by the operator, the remaining waste in the second collection box is pushed out by the push-out component, so that the waste is automatically collected into the interior of the third collection box, thereby completing the collection of large-sized waste.

[0020] Preferably, the ejection assembly includes a pusher that is slidably disposed on the side of the second collection box away from the third collection box. A push plate for ejecting waste is fixed at one end of the pusher near the bottom wall of the second collection box, and top posts for opening the box door are symmetrically fixed on one side of the surface of the pusher.

[0021] By adopting the above technical solution, the pusher provides power to the push plate, which pushes the large-sized waste material closer to the box door. As the push plate approaches the box door, the pusher drives the top column to approach the box door, causing the end of the top column away from the pusher to impact the box door. This causes the end of the box door near the third collection box to move away from the second collection box, leaving the end of the second collection box near the box door in an open state. This allows the pusher to push the large-sized waste material into the third collection box, completing the collection of the large-sized waste material.

[0022] Preferably, a second collection port for discharging small-sized waste is provided on one side of the surface of the sorting box, and a collection box for collecting small-sized waste is inserted into the side of the sorting box near the second collection port.

[0023] By adopting the above technical solution, small-sized waste is automatically guided into the second collection port by a fixed and inclined guide plate, so that the small-sized waste can fall directly into the collection box, thereby completing the collection of small-sized waste.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The filter plate can classify film cutting waste according to size through the filter holes. Small-sized waste enters the first collection box through the guide plate and the second collection port. Large-sized waste and finished products enter the second collection box through the collection plate and the first collection port after the filter plate is flipped. The large-sized waste in the second collection box is pushed into the third collection box by the push-out component. This realizes the automatic classification and separate collection of waste of different sizes, so that film waste of different sizes can be processed accordingly, and improve the recycling process of film waste.

[0026] 2. The filter plate is connected to the drive plate through the positioning plate. The positioning and fixing are achieved by means of positioning blocks, springs and other structures. When the filter plate needs to be replaced according to the waste of different sizes, only external force needs to be applied to make the positioning block disengage from the positioning groove, and the positioning plate can be taken out from the drive plate. The operation is simple and can adapt to different waste processing needs, improving the flexibility and applicability of the mechanism. Attached Figure Description

[0054] The following is in conjunction with the appendix Figures 1-13 This application will be described in further detail.

[0055] This application discloses a film cutting waste collection mechanism.

[0056] Reference Figure 1 A film cutting waste collection mechanism includes a cutting machine body 1. The cutting machine body 1 is an automated or semi-automatic mechanical device specifically used for the precise cutting and trimming of certain films (such as PET film, BOPP film, ordinary packaging film, and insulating film). The cutting machine body 1 belongs to the prior art, and the detailed principle of the cutting machine body 1 will not be described in detail. A guide plate 2 is provided on one side of the surface of the cutting machine body 1. The side of the guide plate 2 is triangular, and the slope angle of the guide plate 2 is 15°. Baffles 21 for guiding waste discharge are fixed on both sides of the surface of the guide plate 2.

[0057] The 15° inclined surface of the guide plate 2 allows the waste material and finished product cut by the cutting machine body 1 to be discharged, preventing the waste material and finished product from accumulating at the end of the cutting machine body 1 near the guide plate 2. The baffle 21 also prevents the waste material and finished product from detaching from the inclined surface of the guide plate 2.

[0058] Reference Figures 1-13 A sorting mechanism 3 for classifying waste materials is provided on the side of the guide plate 2 away from the surface of the cutting machine body 1. The sorting mechanism 3 includes a sorting box 31 fixed on the side of the guide plate 2 away from the surface of the cutting machine body 1. The lowest end of the inclined surface of the guide plate 2 is on the same vertical line as the inner wall of the sorting box 31, so that the waste materials and finished products discharged through the guide plate 2 can fall into the interior of the sorting box 31. A drive box 32 is fixed on one side of the surface of the sorting box 31. A micro motor 321 is fixed inside the drive box 32. A worm 322 is fixed at the output end of the micro motor 321. The end of the worm 322 away from the micro motor 321 is rotatably connected to the side wall of the drive box 32 through a bearing. The bearing includes an inner ring, an outer ring, rolling elements, and a cage. The bearing is an existing and mature technology. The principle of the bearing will not be described in detail. The outer ring of the bearing at the end of the worm 322 away from the micro motor 321 is fixed to the side wall of the drive box 32. A worm wheel 33 that meshes with the worm 322 is rotatably provided inside the drive box 32.

[0059] A limiting shaft 331 is fixed at the center of the end of the worm gear 33 away from the sorting box 31. The end of the limiting shaft 331 away from the worm gear 33 is rotatably mounted on the side wall of the drive box 32 via a bearing. The outer ring of the bearing at the end of the limiting shaft 331 away from the worm gear 33 is fixed to the side wall of the drive box 32. A drive shaft 34 is fixed at the end of the worm gear 33 away from the limiting shaft 331. The surface of the drive shaft 34 is rotatably connected to the surface of the sorting box 31 near the drive box 32 via a bearing. A drive plate 35 is fixed at the end of the drive shaft 34 away from the worm gear 33. A section is opened on the side wall of the sorting box 31 near the guide plate 2. There is a rotating space 312 for flipping the drive plate 35. The rotating space 312 can support the drive plate 35 to flip by 15°. The overall space of the rotating space 312 is much larger than the overall size of the drive plate 35. After the drive plate 35 flips by 15°, the surface of the drive plate 35 abuts against the inner wall of the limiting groove 311. A connecting shaft is fixed at the end of the drive plate 35 away from the transmission shaft 34. The end of the connecting shaft away from the drive plate 35 is rotatably connected to the side wall of the rotating space 312 through a bearing. The outer ring of the bearing at the end of the connecting shaft away from the drive plate 35 is fixed to the side wall of the rotating space 312.

[0060] It should be noted that the gear ratio between the worm gear 33 and the worm 322 is set to 1:10, that is, for every 10 rotations of the worm 322, the worm gear 33 rotates once, which meets the requirements of low speed and high torque output. The specific ratio can be designed according to actual needs.

[0061] The micro motor 321 provides power to the worm gear 322, causing the worm gear 322 to rotate. The worm gear 322 drives the worm wheel 33 to rotate, and the worm wheel 33 drives the transmission shaft 34 to rotate, thereby causing the transmission shaft 34 to drive the drive plate 35 to rotate within the rotation space 312.

[0062] Reference Figures 1-13 A limiting plate 341 for limiting the position of the drive shaft 34 is fixed on the surface of the drive shaft 34. A limiting groove 311 for rotating the limiting plate 341 is opened on the side of the sorting box 31 near the drive box 32. The limiting groove 311 can support the limiting plate 341 to rotate 15°. Before the drive shaft 34 rotates, the surface of the limiting plate 341 abuts against the inner wall of the limiting groove 311 away from the micro motor 321. After the drive shaft 34 rotates, the surface of the limiting plate 341 abuts against the inner wall of the limiting groove 311 near the micro motor 321.

[0063] It should be noted that micro switches 38 are fixed on both sides of the inner wall of the limit groove 311, and the controller module and driver module are installed inside the drive box 32. A push button switch is installed on the side of the drive box 32 away from the sorting box 31.

[0064] Connect the micro motor 321, controller module, driver module, push button switch, and micro switch 38 to the power supply respectively. Connect the rotating space 312 to the driver module, connect the driver module to the controller module, and connect the controller module to the push button switch and micro switch 38.

[0065] When the forward button of the push-button switch is pressed, the push-button switch controls the micro motor 321 to rotate counterclockwise. When the reverse button of the push-button switch is pressed, the push-button switch controls the micro motor 321 to rotate clockwise.

[0066] During the rotation of the drive shaft 34, the limiting plate 341 is rotated in the limiting groove 311. When the surface of the limiting plate 341 comes into contact with the contact of the micro switch 38, the micro switch 38 controls the micro motor 321 to turn off, so that the micro motor 321 stops running.

[0067] The micro motor 321 is controlled by micro switch 38 to open and close, so that the drive shaft 34 can automatically close when it rotates to 15°, preventing the drive plate 35 from colliding with the inner wall of the limit groove 311.

[0068] Reference Figures 1-13 A slot is provided on one side of the surface of the drive plate 35. A positioning plate 37 is inserted into the slot. The surface of the positioning plate 37 abuts against the inner wall of the slot. Accommodation spaces 351 are provided on both sides of the inner wall of the slot. A positioning block 361 abuts against the inner wall of the accommodation space 351. A spring 36 is fixed in the middle of the side of the positioning block 361 away from the positioning plate 37. The end of the spring 36 away from the positioning block 361 is fixed to the side wall of the accommodation space 351. The end of the positioning block 361 away from the spring 36 is hemispherical. Positioning grooves 371 that match the end of the positioning block 361 away from the spring 36 are provided on both sides of the surface of the positioning plate 37. Guide blocks 362 are symmetrically fixed on the surface of the end of the positioning block 361 away from the positioning plate 37. Guide grooves 352 that match the guide blocks 362 are provided on both sides of the inner wall of the accommodation space 351. The surface of the guide blocks 362 abuts against the inner wall of the guide grooves 352, so that the guide blocks 362 can slide stably inside the guide grooves 352.

[0069] It should be noted that the calculation formula for spring 36 is: F = kx, where F is the external force on spring 36, in N, k is the spring constant of spring 36, in N / m, and x is the deformation of spring 36, in m. The elastic force of spring 36 is then calculated so that it can be used in this application.

[0070] By inserting the positioning plate 37 into the slot on one side of the drive plate 35, the positioning plate 37 presses against the inner wall of the slot as it enters the slot, causing the positioning block 361 to retract into the receiving space 351. This causes the positioning block 361 to press against the spring 36, deforming the spring 36. When the positioning grooves 371 on both sides of the positioning plate 37 move to face the positioning block 361, the positioning block 361 loses the pressing force from the positioning plate 37, and the spring 36 loses the pressing force from the positioning block 361. As a result, the positioning block 361 is ejected into the positioning groove 371 by the rebound force of the spring 36, thus fixing the positioning plate 37 inside the slot and securing the positioning plate 37 to the drive plate 35.

[0071] Reference Figures 1-13 A filter plate 372 for sorting waste is fixedly provided on one side of the surface of the positioning plate 37, and the filter plate 372 is located inside the sorting box 31. The filter plate 372 is in a horizontal state when the micro motor 321 is not started. The two sides of the surface of the filter plate 372 abut against the inner wall of the sorting box 31 to prevent large-sized waste from leaking directly out through the gap between the two sides of the surface of the filter plate 372 and the inner wall of the sorting box 31 to the bottom wall of the sorting box 31. A handle 375 is symmetrically fixed on one side of the surface of the filter plate 372. The surface of the filter plate 372 is provided with filter holes 373 for filtering waste and finished products. The diameter of the filter holes 373 is 6mm, and the distance between every two filter holes 373 is 5mm, which can effectively separate waste from 5mm to 20mm. An abutment strip 374 is fixed on the side of the filter plate 372 away from the cutting machine body 1. A guide plate 316 for discharging sorted waste is fixed on the inner wall of the sorting box 31. The guide plate 316 is in an inclined state.

[0072] A first collection port 313 for discharging large-sized waste and finished products is provided on the side of the sorting box 31 away from the guide plate 2. A collection plate 314 is fixed on the inner wall of the first collection port 313. The collection plate 314 is inclined at 15°. An abutment groove 315 is provided at the end of the collection plate 314 near the filter plate 372, which abuts against the abutment strip 374. After the filter plate 372 is rotated 15°, the surface of the abutment strip 374 abuts against the inner wall of the abutment groove 315, and the inclined surface of the filter plate 372 and the inclined surface of the collection plate 314 are on the same inclined surface, so that the inclined surface of the collection plate 314 serves as an extension surface of the filter plate 372. A second collection box 5 for collecting large-sized waste and finished products is fixed on the side of the sorting box 31 near the first collection port 313.

[0073] The drive plate 35 rotates, causing the positioning plate 37 to rotate. The positioning plate 37 then rotates the filter plate 372, which in turn rotates the abutment strip 374. After the filter plate 372 rotates 15°, the abutment strip 374 enters the abutment groove 315 and abuts against the inner wall of the groove. This causes the surface of the filter plate 372 after rotating 15° to be on the same inclined plane as the collection plate 314. The collection plate 314 then serves as an extension surface of the filter plate 372, allowing large-sized waste and finished products on the surface of the filter plate 372 to be guided onto the inclined plane of the collection plate 314. The waste and finished products are then guided into the first collection port 313 via the collection plate 314, thus allowing the large-sized waste and finished products to be guided into the second collection box 5, achieving the collection of large-sized waste and finished products.

[0074] Reference Figures 1-12 The inner wall of the sorting box 31 is fixed with a guide plate 316. The guide plate 316 is set in an inclined state inside the sorting box 31 with an inclination angle of 15-20°, so that small-sized waste after being sorted by the filter plate 372 can be automatically discharged into the sorting box 31 through the inclined surface of the guide plate 316. A second collection port 317 for discharging small-sized waste is opened on one side of the surface of the sorting box 31. A collection box 4 for collecting small-sized waste is set on the side of the surface of the sorting box 31 near the second collection port 317. An insertion block 41 is symmetrically fixed on the side of the collection box 4 near the surface of the sorting box 31. An insertion groove 318 adapted to the insertion block 41 is opened on the side of the surface of the sorting box 31 near the collection box 4. The surface of the insertion block 41 abuts against the inner wall of the insertion groove 318.

[0075] The small-sized waste material after sorting is automatically guided into the collection box 4 through the second collection port 317 by the guide plate 316, thus completing the collection of small-sized waste material. The collection box 4 is detachably installed on one side of the sorting box 31, which is convenient for users to quickly replace the collection box 4.

[0076] Reference Figures 1-6 A door 51 is provided on one side of the surface of the second collection box 5. A third collection box 7 for collecting the ejected waste is provided below the surface of the second collection box 5 near the door 51. The end of the door 51 near the third collection box 7 can be separated from the surface of the second collection box 5. The end of the door 51 away from the third collection box 7 is hinged to the surface of the second collection box 5. An ejection component 6 for ejecting waste is provided inside the second collection box 5.

[0077] The ejection assembly 6 includes a pusher 61 slidably disposed on the side of the surface of the second collection box 5 away from the third collection box 7. A guide block 611 is symmetrically fixed on the side of the pusher 61 near the surface of the second collection box 5. A guide groove 52 adapted to the guide block 611 is opened on the side of the second collection box 5 near the pusher 61. The surface of the guide block 611 abuts against the inner wall of the guide groove 52, so that the guide block 611 can slide stably inside the guide groove 52. A push plate 63 for ejecting waste is fixed at one end of the pusher 61 near the bottom wall of the second collection box 5. The side of the push plate 63 is trapezoidal. The end of the push plate 63 away from the pusher 61 abuts against the inner wall of the second collection box 5. A top post 62 for opening the box door 51 is symmetrically fixed on one side of the surface of the pusher 61. The top post 62 is composed of a column and a hemisphere, and the end of the top post 62 away from the pusher 61 is hemisphere.

[0078] After the finished products are sorted out from inside the second collection box 5, the pusher 61 provides power to the pusher plate 63, which pushes the large-sized waste material closer to the box door 51. As the pusher plate 63 approaches the box door 51, the pusher 61 drives the top column 62 to approach the box door 51, so that the end of the top column 62 away from the pusher 61 bumps against the box door 51, so that the end of the box door 51 near the third collection box 7 moves away from the second collection box 5, and the end of the second collection box 5 near the box door 51 is in an open state, so that the pusher plate 63 pushes the large-sized waste material into the third collection box 7, thus completing the collection of the large-sized waste material.

[0079] It should be noted that: guide plate 2, baffle 21, and filter plate 372 are made of 304 stainless steel; sorting box 31, collection plate 314, guide plate 316, and positioning plate 37 are made of ABS; the inner walls of abutment groove 315 and insertion groove 318 are provided with wear-resistant nylon layer; push frame 61 and top column 62 are made of No. 45 steel; and push plate 63 is made of nylon.

[0080] In this application, the cutting machine body 1 and the guide plate 2 are separate. The end of the guide plate 2 away from the sorting box 31 is aligned with the discharge port of the cutting machine body 1, so that the waste and finished products on the surface of the cutting machine body 1 automatically slide onto one side of the surface of the guide plate 2, thereby realizing the joint collection of waste and finished products.

[0081] Before use, the filter plate 372 is in a horizontal position, and the side of the push plate 63 away from the door 51 abuts against the inner wall of the collection box 2 5 away from the door 51.

[0082] The implementation principle of the film cutting waste collection mechanism in this application embodiment is as follows: Before cutting, the user selects a suitable filter plate 372 according to the size of the waste generated during the cutting process. After selection, the user pulls the handle 375 on the surface of the filter plate 372 and inserts the positioning plate 37 into the slot on one side of the drive plate 35. When the positioning plate 37 enters the slot, the surface of the positioning plate 37 abuts against the inner wall of the slot, causing the positioning plate 37 to press the positioning block 361 during the process of entering the slot, causing the positioning block 361 to retract into the interior of the accommodating space 351, and causing the positioning block 361 to press the spring 36, causing the spring 36 to deform.

[0083] When the positioning grooves 371 on both sides of the surface of the positioning plate 37 move to be directly opposite the positioning block 361, the positioning block 361 loses the pressing force from the positioning plate 37, causing the spring 36 to lose the pressing force from the positioning block 361. As a result, the positioning block 361 is ejected into the positioning groove 371 by means of the spring 36's rebound force, thus fixing the positioning plate 37 inside the slot and fixing the positioning plate 37 and the drive plate 35 together. This allows the filter plate 372 to be installed inside the sorting box 31, enabling the filter plate 372 to be detachably installed. This makes it convenient for users to replace the filter plate 372 with different pore sizes according to the size of different waste materials, thus improving the applicability of this application.

[0084] The film is then placed on the surface of the cutting machine body 1, and the cutting machine body 1 is started to cut the film. After the film is cut, the waste and finished products are transported to the surface of the guide plate 2 through the cutting machine body 1. The cutting process and the conveying process are existing technologies, and their principles will not be described in detail. The waste and finished products are guided into the sorting box 31 through the inclined surface of the guide plate 2, so that the waste and finished products fall onto the surface of the filter plate 372, so that the filter holes 373 sort the waste. Small-sized waste is guided into the inclined surface of the guide plate 316 through the filter holes 373. The guide plate 316 automatically guides the sorted small-sized waste into the collection box 4 through the second collection port 317, thus completing the collection of small-sized waste.

[0085] After a batch of cut films is introduced into the sorting box 31, the forward rotation button of the push-button switch is pressed. The push-button switch controls the micro motor 321 to start, causing the output end of the micro motor 321 to rotate counterclockwise. This micro motor 321 provides power to the worm gear 322, causing the worm gear 322 to rotate counterclockwise. The worm gear 322 drives the clockwise rotation of the worm wheel 33, which in turn drives the transmission shaft 34 to rotate clockwise. The transmission shaft 34 then drives the drive plate 35 to rotate clockwise within the rotation space 312. The drive plate 35, in turn, drives the positioning plate 37 to rotate clockwise. The positioning plate 37 drives the filter plate 372 to rotate clockwise, and the filter plate 372 drives the abutment strip 374 to rotate clockwise. During the clockwise rotation, the transmission shaft 34 drives the limiting plate 341 to flip in the limiting groove 311. When the surface of the limiting plate 341 abuts against the contact of the micro switch 38, the micro switch 38 controls the micro motor 321 to turn off, so that the micro motor 321 stops running, thereby controlling the rotation angle of the transmission shaft 34, that is, controlling the rotation angle of the filter plate 372, and thus limiting the rotation angle of the filter plate 372 to 15°.

[0086] After the filter plate 372 is rotated 15° clockwise, the abutment strip 374 enters the abutment groove 315 and abuts against the inner wall of the abutment groove 315, so that the surface of the filter plate 372 after rotating 15° is on the same inclined plane as the collection plate 314, so that the collection plate 314 serves as an extension surface of the filter plate 372, thereby guiding the large-sized waste and finished products on the surface of the filter plate 372 into the inclined plane of the collection plate 314, and then into the interior of the first collection port 313 through the collection plate 314, thereby guiding the large-sized waste and finished products into the collection box 5, realizing the collection of large-sized waste and finished products.

[0087] The user separates the finished products from the large-sized waste inside collection box 2 5, picking out the finished products. After sorting out the finished products inside collection box 2 5, the user pushes the pusher 61 to provide power to the pusher plate 63, causing the pusher plate 63 to push the large-sized waste gradually closer to the box door 51. As the pusher plate 63 approaches the box door 51, the pusher 61 drives the top column 62 to approach the box door 51, causing the end of the top column 62 away from the pusher 61 to bump against the box door 51, causing the end of the box door 51 near collection box 3 7 to move away from collection box 2 5, so that the end of collection box 2 5 near the box door 51 is in an open state, thereby allowing the pusher plate 63 to push the large-sized waste into the collection box 3 7, completing the collection of the large-sized waste.

[0088] This application enables the separate processing of small-sized and large-sized waste materials after classification. Small-sized waste materials can be directly fed into the melting equipment, while large-sized waste materials can be cut and processed according to requirements. This eliminates the energy consumption of equipment required for mixed crushing, such as the power consumption of the crusher, and the material loss during the crushing process, such as the dust waste when the film is crushed.

[0089] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
