Description

Technical Field

[0001] The present invention relates to the technical field of carton crushing, and in particular to a crushing device and method for recycling environmentally friendly carton. Background Art

[0002] Environmentally friendly cartons refer to cartons that have less impact on the environment during production, use and recycling and meet environmental protection requirements. Environmentally friendly cartons are usually made from renewable resources, such as recycled pulp or wood fiber from sustainably managed forests, and use a large amount of recycled pulp as the main raw material to reduce the demand for virgin wood.

[0003] As for the recycling and shredding of environmentally friendly cartons, the volume of the shredded cartons is greatly reduced, which is convenient for transportation and storage. The shredded cartons can be stacked more tightly, reducing transportation costs and storage space. The shredding process quickly breaks down the cartons into smaller pieces, which is convenient for subsequent processing and treatment, and improves the overall recycling efficiency.

[0004] For example, a Chinese patent with publication number CN112691766A discloses a carton crushing and compression device; it relates to the field of carton crushing technology, including a main body, a rotating cylinder is installed on the upper inner side of the main body, and a blade is connected to the outer wall of the rotating cylinder, a motor is installed at one end of the rotating cylinder, and the output shaft of the motor is horizontally connected to the main body, a discharge port is opened in the middle of the inner side of the main body, and a fixed rope is connected to the inside of the discharge port, a collection box is arranged at the lower inner side of the main body, and a pressure plate is slidably connected to the inner wall of the collection box. Its beneficial effect is: the carton crushing and compression device, through manual gripping of the movable handle, makes the movable handle drive the movable clamp connected to it by the steel wire to open through the operation of the connecting rod transmission, and clamps the large block of carton crushed below the rotating cylinder, so that it is adjusted from an inclined state to a vertical state, so that it continues to contact with the blade for secondary crushing.

[0005] However, the above device still has some shortcomings in actual use:

[0006] 1. The above device adjusts the angle of the carton inside the rotating drum to facilitate the contact between the carton and the blade, thereby performing multiple crushing operations. However, the adjustment of the angle requires manual operation, and manual adjustment of the angle takes time, which will reduce the overall production efficiency and cannot achieve continuous and efficient production, resulting in limited production capacity.

[0007] 2. The above device needs to place the sheet-shaped cartons inside the rotating drum for crushing. However, for some unprocessed cartons, the cartons in the box state may not be able to enter the rotating drum, so the scope of application is limited.

[0008] Therefore, under the viewpoints stated above, it is of great significance to improve and perfect the existing carton crushing and compressing device, to improve the problem of low production efficiency caused by manual operation, to increase the degree of automation and reduce human intervention, to achieve continuous and efficient production, and to further improve the pretreatment of cartons to be crushed, which is convenient for crushing the cartons.

DETAILED DESCRIPTION

[0040] The following is combined with Figures 1 - 10 Embodiments of the present invention are described in detail.

[0041] The embodiment of the present application discloses a shredding device and method for recycling environmentally friendly cartons, which explains that the present invention is mainly used in the process of carton shredding, and can avoid the need for manual operation and reduce the overall production efficiency in terms of technical effect; further, the present invention can also solve the problem that some unprocessed cartons and cartons in a box state may not be able to enter the rotating drum and have a small scope of application.

[0042] Embodiment 1:

[0043] Reference Figure 1 , Figure 2 and Figure 3 As shown, it includes a support frame 1, on which a main conveyor belt 10 is arranged, and a crushing piece 2 is arranged on one side of the length direction of the main conveyor belt 10 to crush the conveyed cartons, and a laser measuring instrument 11 is arranged on the upper side of the other side of the support frame 1 to detect whether the carton is in a compressed or folded state. After the detection is completed, the uncompressed and folded cartons will be further processed.

[0044] The laser measuring instrument 11 is preferably an existing laser measuring instrument 11 for detecting height, so as to detect the height of the carton conveyed by the main conveyor belt 10 to determine whether the carton is in a compressed sheet shape.

[0045] A steering member 3 is provided on the support frame 1. An unpacked cardboard box will leave the main conveyor belt 10 through the steering member 3 and then be compressed. The steering member 3 includes a steering shaft 30 which is rotatably arranged on one side of the main conveyor belt 10 along the height direction of the support frame 1. A steering plate 31 is arranged on the steering shaft 30. An accommodation groove is formed on the steering plate 31, and a plurality of steering rollers 32 are equidistantly arranged in the accommodation groove. The rotation directions of the plurality of steering rollers 32 are the same.

[0046] When it is detected that the cardboard box needs to be compressed, the steering plate 31 rotates to be misaligned above the main conveyor belt 10. Subsequently, the steering rollers 32 rotate, driving the cardboard box to move along the rotation direction of the steering rollers 32 and fall from the main conveyor belt 10 for subsequent compression processing.

[0047] The function of this setting is that when an unpacked cardboard box falls into the crushing member 2 for crushing, it may cause blockage at the entrance or inside of the crushing equipment, affecting normal operation, limiting the processing capacity of the crushing equipment, reducing the crushing efficiency. Separating the compressed and unpacked cardboard boxes for processing can improve the crushing efficiency and reduce the risk of equipment blockage during the crushing of unpacked cardboard boxes.

[0048] Refer to Figure 1 、 Figure 2 and Figure 6 As shown in the figures, it is a schematic structural diagram for conveying the cardboard boxes that need to be compressed; specifically, a secondary conveyor belt 12 is inclinedly arranged on one side of the main conveyor belt 10. A compression member 4 for compressing the cardboard boxes is arranged above the secondary conveyor belt 12. A compression box 13 is arranged on the side of the secondary conveyor belt 12 away from the main conveyor belt 10. One side of the compression box 13 is connected to a square conduit 14 on the support frame 1. One end of the square conduit 14 communicates with the compression box 13, and the other end is connected to the crushing member 2.

[0049] The cardboard boxes that need to be compressed on the main conveyor belt 10 will fall onto the secondary conveyor belt 12 and enter the compression box 13 through the secondary conveyor belt 12 for compression processing. The compressed cardboard boxes will pass through the square conduit 14 and then be pulverized by the crushing member 2.

[0050] Refer to Figure 1 and Figure 4 As shown in the figures, it is a schematic structural diagram for pulverizing the cardboard boxes; specifically, the crushing member 2 includes a crushing box 20. Inside the crushing box 20, crushing rollers 21 are symmetrically and rotatably arranged. Along the axis of the crushing rollers 21, multiple groups of crushing blocks 22 are equidistantly arranged. The crushing blocks 22 on the two crushing rollers 21 are arranged staggeredly.

[0051] The rotation directions of the two crushing rollers 21 are opposite.

[0052] By the relative rotation of the crushing rollers 21 and using the crushing blocks 22, the cardboard boxes falling into the crushing box 20 are crushed.

[0053] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in

[0054] and

[0055] Refer to Figure 5 and Figure 6 As shown in

[0056] which is the schematic structural diagram of the structure for driving the uncompressed cardboard box to turn; specifically, a driving member 5 for driving the turning roller 32 to rotate is further provided on the support frame 1. The driving member 5 includes a driving shaft 50. The turning roller 32 is rotatably arranged in the placement groove on the turning plate 31 by driving the driving shaft 50. One of the driving shafts 50 penetrates through one end of the turning plate 31 close to the main conveyor belt 10. A driving gear 51 is installed at one end of the driving shaft 50 located on the turning plate 31. A plurality of mating teeth 52 are equidistantly installed on one side of the main conveyor belt 10 close to the turning shaft 30. The plurality of mating teeth 52 are movably engaged with the driving gear 51.

[0057] When the laser measuring instrument 11 detects that the conveyed cardboard box is a cardboard box that needs to be compressed, the turning plate 31 rotates. One of the driving shafts 50 on the turning plate 31 will approach the main conveyor belt 10. During this process, the mating teeth 52 on the main conveyor belt 10 will be engaged with the driving gear 51 on the driving shaft 50, driving the driving shaft 50 to rotate, driving the turning roller 32 to rotate, and the rotation of the plurality of turning rollers 32 can drive the cardboard box on the main conveyor belt 10 to approach the auxiliary conveyor belt 12 along the rotation direction of the turning roller 32. Figure 1 、 Figure 5 and Figure 6As shown, it is a schematic structural diagram of the structure that drives the pressing plate 43 to contact the auxiliary conveyor belt 12; specifically, a lifting member 6 for driving the pressing plate 43 to lift is further provided on the support frame 1. In order to prevent the pressing plate 43 from blocking the transportation of the cardboard box by the auxiliary conveyor belt 12 and thus affecting the pressing of the cardboard box by the pressing plate 43, the function of the lifting member 6 is that before the cardboard box falls onto the auxiliary conveyor belt 12, the pressing plate 43 is located above the cardboard box and will not affect the transportation of the cardboard box. Subsequently, the pressing plate 43 is driven to descend so that the pressing plate 43 is located on the side of the cardboard box away from the compression box 13, facilitating the cooperation between the pressing plate 43 and the compression box 13 to press the cardboard box.

[0058] The lifting member 6 includes a threaded rod 60. A driving groove communicating with the inside of the pressing plate 43 is formed inside the extension rod 42. The threaded rod 60 is arranged inside the pressing plate 43 and extends into the driving groove. A lifting gear 61 is installed at one end of the extension rod 42 close to the threaded seat 41. A lifting rack 62 meshing with the lifting gear 61 is arranged on the support frame 1 along the length direction of the reciprocating screw rod 40.

[0059] During the movement of the threaded seat 41, the extension rod 42 on the threaded seat 41 will move synchronously with the threaded seat 41. During the movement, the lifting gear 61 on the extension rod 42 will mesh with the lifting rack 62, driving the extension rod 42 to rotate in the reverse direction, and then driving the threaded rod 60 threadedly connected to the extension rod 42 to drive the pressing plate 43 to move along the length direction of the extension rod 42, achieving the purpose of driving the pressing plate 43 to lift and lower.

[0060] A stabilizing member 7 for preventing the pressing plate 43 from rotating is further provided on the support frame 1. The stabilizing member 7 includes a stabilizing shaft 70. The stabilizing shaft 70 is symmetrically arranged on both sides of the reciprocating screw rod 40 along the length direction of the reciprocating screw rod 40. Stabilizing blocks 71 are symmetrically arranged at the upper end of the pressing plate 43, and the stabilizing blocks 71 are sleeved on the stabilizing shaft 70.

[0061] Through the cooperation between the stabilizing blocks 71 on both sides and the stabilizing shaft 70, the threaded rod 60 is prevented from rotating following the rotation of the extension rod 42, ensuring that the rotation of the extension rod 42 can drive the threaded rod 60 to lift and lower.

[0062] Refer to Figure 3 and Figure 7 As shown, it is a schematic structural diagram for transporting the pressed cardboard box; specifically, a plurality of guide rollers 15 are equidistantly arranged at the bottom and on the sides of the square conduit 14 and the compression box 13. The guide rollers 15 located on the same straight line are synchronously rotated through sprockets and chains.

[0063] The pressed cardboard box in the compression box 13 is transported to above the crushing box 20 through the square conduit 14 by the rotation of the guide rollers 15.

[0064] Embodiment 2:

[0065] On the basis of the first embodiment, in order to further improve the coherence of squeezing the carton during the transportation process in the actual application of the present device, a synchronization unit 8 is also proposed, which is conducive to immediately transporting the squeezed carton after squeezing the carton, improving the coherence of the present device, and when facing a carton that does not need to be squeezed, making the guide roller 15 always in a standby state, saving transportation costs.

[0066] Refer to Figure 7 、 Figure 8 and Figure 9 As shown in [relevant figures], which is the structural schematic diagram for driving the guide roller 15 to move; specifically, the synchronization unit 8 includes a connecting shaft 80, the connecting shaft 80 is rotatably installed on one side of the square conduit 14 close to the main conveyor belt 10, the connecting shaft 80 is connected to the rotating shaft of one of the guide rollers 15, and a mating shaft 81 coaxially and movably connected to the connecting shaft 80 is arranged on the support frame 1, the mating shaft 81 is connected to the output shaft of the auxiliary conveyor belt 12 through a bevel gear set, and the mating shaft 81 rotates synchronously with the movement of the auxiliary conveyor belt 12.

[0067] After the carton in the compression box 13 is squeezed, it is necessary to drive the guide roller 15 to rotate to convey the carton.

[0068] The mating shaft 81 moves synchronously with the auxiliary conveyor belt 12 through the bevel gear set. When the connecting shaft 80 is connected to the mating shaft 81, it can drive the guide roller 15 to rotate.

[0069] Refer to Figure 7 、 Figure 8 and Figure 9 As shown in [relevant figures], which is the structural schematic diagram for driving the connecting shaft 80 and the mating shaft 81 to be movably matched; specifically, a synchronizing member 82 for the connecting shaft 80 and the mating shaft 81 to rotate synchronously is also arranged on the support frame 1, the synchronizing member 82 includes a sliding shaft 820, a through chute is opened at one end of the connecting shaft 80 far from the square conduit 14, the sliding shaft 820 is slidably arranged inside the chute through a spring, a plurality of synchronizing grooves are equidistantly arranged along the axis of the sliding shaft 820 at one end far from the square conduit 14, a mating block 821 is slidably arranged in the synchronizing groove through a spring, a plurality of mating grooves 822 corresponding to the mating block 821 are axially opened at one end of the mating shaft 81 close to the connecting shaft 80, and one end of the mating shaft 81 close to the connecting shaft 80 is arc-shaped.

[0070] Drive the sliding shaft 820 close to the mating shaft 81. When the mating block 821 on the sliding shaft 820 approaches the mating shaft 81, it will cooperate with the arc end on the mating shaft 81 and slide into the synchronization groove until the sliding shaft 820 completely enters the mating groove 822 on the mating shaft 81. During this process, the mating shaft 81 continues to rotate until the mating groove 822 on the mating shaft 81 corresponds to the mating block 821. At this time, the sliding shaft 820 is connected to the mating shaft 81, and the rotation of the mating shaft 81 can drive the sliding shaft 820 to rotate, and then drive the connecting shaft 80 to rotate.

[0071] Refer to Figure 7 、 Figure 8 and Figure 9 As shown in, that is, the structural schematic diagram of driving the sliding shaft 820 to slide and engage with the mating shaft 81 in the direction; specifically, the sliding shaft 820 slides and engages with the mating shaft 81 through the fitting 83. The fitting 83 includes a driving ring 830 sleeved outside the sliding shaft 820. A fitting plate 831 is slidably arranged on the outside of the square conduit 14 along its width direction through a telescopic rod. A contact plate 832 is slidably arranged at one end of the fitting plate 831 close to the sliding shaft 820. An L-shaped driving plate 833 is installed on one side of the threaded seat 41 close to the sliding shaft 820. An abutting plate 834 is slidably arranged at one end of the driving plate 833 close to the sliding shaft 820 through a spring. Both the abutting plate 834 and one end of the contact plate 832 close to the sliding shaft 820 are symmetrically inclined.

[0072] When the driving plate 833 approaches the compression box 13 along with the threaded seat 41, the abutting plate 834 will contact the fitting plate 831. At this time, the contact plate 832 on the fitting plate 831 will approach the driving ring 830 along with the fitting plate 831. When the contact plate 832 approaches the driving ring 830, the contact plate 832 contracts under the reverse action of the driving ring 830, elongates after passing through the driving ring 830. When the extrusion is completed. The contact plate 832 will move away from the compression box 13 along with the threaded seat 41. At this time, the contact plate 832 will push the driving ring 830 to move towards the mating shaft 81, driving the sliding shaft 820 to engage with the mating shaft 81 and driving the guide roller 15 to rotate.

[0073] During operation: In the first step, the cardboard boxes to be crushed are conveyed through the main conveyor belt 10. When passing under the laser measuring instrument 11, it is tested by the laser measuring instrument 11 whether the cardboard box is in a compressed or folded sheet form. The sheet-shaped cardboard box will pass above the main conveyor belt 10 and fall into the crushing box 20, and the cardboard box is crushed by the crushing roller 21.

[0074] Step 2: When the laser measuring instrument 11 detects that the carton is not a sheet, the steering shaft 30 rotates, driving the steering plate 31 on the steering shaft 30 to rotate until the rotation angle of the steering plate 31 corresponds to the auxiliary conveyor belt 12. Then, the driving gear 51 connected to one of the steering rollers 32 on the steering plate 31 cooperates with the matching tooth 52 on the main conveyor belt 10, driving the steering roller 32 to rotate, driving the carton on the main conveyor belt 10 to fall onto the auxiliary conveyor belt 12.

[0075] Step 3: Then the reciprocating screw 40 rotates, carrying the threaded seat 41 along the movement direction of the auxiliary conveyor belt 12. During the movement, the lifting gear 61 connected to the extension rod 42 on the threaded seat 41 will engage with the lifting rack 62, driving the extension rod 42 to rotate, thereby driving the threaded rod 60 connected to the extension rod 42 to descend, and then the extrusion plate 43 is synchronously descended with the threaded rod 60 until the bottom of the extrusion plate 43 contacts the upper surface of the auxiliary conveyor belt 12, and moves with the threaded seat 41 to extrude the carton inside the compression box 13.

[0076] Step 4: After the extrusion is completed, during the movement of the threaded seat 41, the abutment plate 834 on the driving plate 833 will synchronously approach the matching plate 831, driving the abutment plate 832 on the matching plate 831 to approach the matching ring, driving the matching ring to bring the sliding shaft 820 to approach the matching shaft 81, until the matching block 821 on the sliding shaft 820 and the matching groove 822 on the matching shaft 81 rotate in coordination, at this time, the connecting shaft 80 will rotate under the drive of the matching shaft 81, driving the guide roller 15 on the square guide tube 14 to rotate, driving the extruded carton to enter the crushing box 20 for crushing.
