Description

Technical Field

[0001] The present application relates to the field of plastic product recycling, and in particular, to a sorting device for recycling plastic products. Background Art

[0002] Plastic bottles are primarily made from materials such as polyethylene or polypropylene, with various organic solvents added. Plastic bottles are widely made from polyester (PET), polyethylene (PE), and polypropylene (PP). After adding the appropriate organic solvents, they are heated to high temperatures and then blow-molded, extruded, or injection-molded through plastic molds. Plastic bottles are primarily used as disposable plastic packaging for liquids or solids such as beverages, foods, pickles, honey, dried fruits, cooking oils, and pesticides. Plastic bottles are characterized by their unbreakable nature, low cost, high transparency, and food-grade raw materials.

[0003] For example, Chinese patent publication number CN112008914A discloses the following technical solution: a device for rapid sorting and recycling plastic bottles, relating to the field of plastic bottle recycling technology. The device comprises: a housing, a movable door rotatably connected to the front end of the housing; a partition; a partition fixedly connected to the interior of the housing, which divides the interior of the housing into a dry area and a wet area, with the tops of the dry and wet areas interconnected; a discharge pipe fixedly connected to the bottom surface of the housing, which is interconnected with the dry area, and a drainage pipe fixedly connected to the bottom surface of the housing, which is interconnected with the wet area; and a conveying mechanism connected to the housing.

[0004] The following problems exist in the prior art: when the liquid detector detects that there is no liquid in the corresponding plastic bottle, the above-mentioned device activates the fan through the controller, so that the outlet of the air outlet pipe located in the shell blows out air flow. Since the air outlet pipe is arranged to be inclined upward, under the action of the air flow, plastic bottles with no residual liquid inside (i.e. empty bottles with smaller mass) can be blown into the dry area. However, the distance between the partition and the air outlet pipe is relatively far, and although the device spreads the plastic bottles flat through the baffle, it does not allow the plastic to pass through the upper end of the air outlet pipe one by one, so that plastic bottles without liquid will be blocked by plastic bottles with liquid; in summary, the above-mentioned device may miss some plastic bottles when separating dry and wet plastic bottles.

[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] Example 1, please refer to Figure 1-Figure 7The present embodiment provides a classification device for recycling plastic products, comprising a processing box 1; a transport box 2, which is fixedly connected to the side of the processing box 1; a lower hopper 3, which is used to guide the plastic bottles to be processed into the transport box 2, and is fixedly connected to the top of the processing box 1; a conveyor belt 41 and a clamping conveyor belt 43 are provided inside the transport box 2, and the conveyor belt 41 is used to stably transport the plastic bottles placed in the transport box 2 to the processing box 1, and the clamping conveyor belt 43 is used to clamp the empty plastic bottles and bring them to a specific position to ensure that they accurately enter the subsequent In the processing area, a fan 42 is installed at the bottom of the transport box 2. Fan 42 uses wind power to blow lighter empty bottles between the clamping conveyor belt 43 for sorting. The inner wall of the transport box 2 is rotatably connected to a rotating rod 44. The outer wall of the rotating rod 44 is fixedly connected to a blade 412 and a rotating block 45. The outer wall of the rotating block 45 is fixedly connected to a sliding shaft 46. The outer wall of the transport box 2 is fixedly connected to a rotating shaft 47. The outer wall of the rotating shaft 47 is fixedly sleeved with a rocking block 48 and a rocking frame 49. The upper end of the rocking block 48 is hinged to a connecting rod 410, and the other end of the connecting rod 410 is fixedly connected to a diverter plate 411. Ventilation holes are provided at the connection between the conveyor belt 41 and the lower end of the transport box 2 and the fan 42. The outer wall of the transport box 2 is provided with a slide 413, and the connecting rod 410 is slidably connected to the slide 413. A partition 7 is fixedly connected to the interior of the processing box 1. This partition 7 serves as a partition, dividing the area within the processing box 1 into different sections for placing different types of plastic bottles. A horizontal plate 8 is fixedly connected to one side of the partition 7. A guide plate 10 is fixedly connected to the upper end of the horizontal plate 8. A through hole is opened in the middle of the horizontal plate 8. The bottom of the processing box 1 is opened with a discharge port and a water outlet 9. The processing box 1 is equipped with a piercing assembly 5 and a stripping assembly 6.

[0037] When in use, first place the plastic bottles into the lower hopper 3, and then the plastic bottles will pass through the lower hopper 3 into the interior of the transport box 2, and then start the conveyor belt 41 to drive the plastic bottles to move in the direction of the processing box 1, and at the same time start the fan 42 to send air to the upper end through its air outlet. At this time, under the blowing of the wind, the blades 412 will drive the rotating rod 44 to rotate. When the rotating rod 44 rotates, it will drive the rotating block 45 to rotate, and then the sliding shaft 46 located on the outer wall of the rotating block 45 will also rotate around the rotating rod 44 at any time. At the same time, the sliding shaft 46 will slide inside the swing frame 49. Since the height of the sliding shaft 46 changes during rotation, it can drive the swing frame 49 to rotate with the rotating shaft 47 as the axis, so the rotating shaft 47 will also swing back and forth, and then the rocking block 48 on the outer wall of the rotating shaft 47 will swing accordingly, and then the rocking The two connecting rods 410 hinged on both sides of the upper end of the pendulum block 48 will show an up-and-down movement trajectory, and then the diverter plates 411 fixedly connected at the other ends of the two connecting rods 410 will also rise and fall accordingly. Then the two diverter plates 411 can allow the plastic bottles to pass through the upper end of the fan 42 one by one. When the empty plastic bottle moves to the upper end of the fan 42, due to its lighter weight, the fan 42 will blow up its upper end, and the empty plastic bottle will be blown between the two clamping conveyor belts 43. When the empty plastic bottle contacts the clamping conveyor belts 43, the two clamping conveyor belts 43 will clamp the empty plastic bottle and transport it to the inside of the processing box 1, and fall to the right side of the partition 7, and be crushed by the crushing roller. The plastic bottle with liquid will not be blown up due to its heavier weight, and will be transported to the left side of the partition 7 in the processing box 1.

[0038] Example 2, please refer to Figure 1-Figure 7 Based on Example 1, the punching assembly 5 includes a pulley A51, which is fixedly mounted on the outer wall of the rotating rod 44. A transmission belt 52 is wound around the outer surface of the rotating rod 44. The other end of the transmission belt 52 is connected to the inner side of the pulley B53 for transmission. A reciprocating screw 55 is fixedly connected to the outer wall of the pulley B53. A fixed block 54 is fixedly connected to the outer wall of the processing box 1. The reciprocating screw 55 is rotatably connected to the fixed block 54. A movable rod 56 is threadedly connected to the outer wall of the reciprocating screw 55. A movable plate 57 is fixedly connected to the side of the movable rod 56. A prick rod 58 is fixedly connected to the surface of the movable plate 57. A fixed shaft 59 is fixedly connected to the inner wall of the processing box 1. The other end of the fixed shaft 59 is fixedly connected to the push block 510. A through groove 511 is formed on the outer wall of the movable plate 57. A movable groove A512 is formed on the side of the processing box 1. The movable rod 56 is slidably connected to the movable groove A512.

[0039] During use, when a plastic bottle filled with liquid falls to the left side of the processing box 1, it will slide down to the upper end of the horizontal plate 8 and the baffle 62 under the action of the guide plate 10. Since the rotating rod 44 is in a rotating state, the pulley A51 outside it will also rotate, and then under the transmission action of the transmission belt 52, it will drive the pulley B53 to rotate, and then the pulley B53 will drive the reciprocating screw rod 55 to rotate, and then the moving rod 56 threadedly connected to the outside of the reciprocating screw rod 55 will reciprocate back and forth under the restriction of the movable groove A512, so the moving rod 56 on the moving rod 55 will reciprocate back and forth under the restriction of the movable groove A512. The movable plate 57 at the other end of the movable rod 56 will also move accordingly, and the movable plate 57 will drive the piercing rod 58 on its outer wall to move toward the plastic bottle, thereby piercing the plastic bottle, and the liquid in the plastic bottle will flow out. When the movable plate 57 is reset along with the movable rod 56, the fixed shaft 59 fixed on the inner wall of the processing box 1 and the pushing block 510 at the other end of the fixed shaft 59 will pass through the through groove 511. When the movable plate 57 moves to the outermost side, the pushing block 510 will push out the plastic bottle stuck in the outer wall of the piercing rod 58, causing the plastic bottle to fall to the upper end of the baffle 62.

[0040] Example 3, please refer to Figure 1-Figure 7 On the basis of Example 1, the stripping assembly 6 includes a guide rail 61, which is fixedly connected to the bottom of the horizontal plate 8. The outer wall of the guide rail 61 is slidably connected to a baffle 62, and the bottom of the baffle 62 is fixedly connected to a block 63. The inner wall of the processing box 1 is rotatably connected to a gear ring 64 and a ratchet 65. The outer wall of the ratchet 65 is fixedly connected to a connecting shaft 66, and the other end of the connecting shaft 66 is fixedly connected to a push rod 67. The inner side of the gear ring 64 is hinged with a pawl 68. The outer wall of the moving rod 56 is fixedly connected to a tooth plate 611 through a connecting block, and the tooth plate 611 is engaged with the gear ring 64. The inner wall of the processing box 1 is fixedly connected to a tension spring 69, and the other end of the tension spring 69 is fixedly connected to the baffle 62. A water filter hole 610 is opened on the outer wall of the baffle 62, and a spring is arranged between the pawl 68 and the inner wall of the gear ring 64.

[0041] When in use, when the plastic bottle is pierced, the liquid inside it will first flow into the interior of the treatment box 1 through the water filter hole 610 at the upper end of the baffle 62, and be discharged from the treatment box 1 through the water outlet 9. When the moving rod 56 moves, it will drive the tooth plate 611 to move, and when the tooth plate 611 moves, it will drive the gear ring 64 engaged therewith to rotate. When the tooth plate 611 moves toward the middle of the treatment box 1, the gear ring 64 rotates clockwise, and at this time the gear ring 64 will not drive the ratchet 65 to rotate through the internal pawl 68. When the moving rod 56 moves toward the edge of the treatment box 1, the tooth plate 611 will drive the gear ring 64 to rotate counterclockwise, and at this time the gear ring 64 will drive the ratchet 65 to rotate through the internal pawl 68, and then the ratchet 65 will rotate. 5 will drive the push rod 67 to rotate through the connecting shaft 66. When the push rod 67 rotates and moves a certain distance, it will contact the stopper 63. Then, when the push rod 67 continues to rotate, it will push the stopper 63 to drive the baffle 62 to slide on the outer wall of the guide rail 61. Then, the baffle 62 will leak the through hole in the middle of the horizontal plate 8, and the punctured plastic bottle will fall to the bottom of the processing box 1. When the push rod 67 rotates to a certain angle, it will disengage from the stopper 63. At this time, under the action of the tension spring 69, the baffle 62 will quickly return to its original position, thereby ensuring that the baffle 62 is closed before the plastic bottle containing liquid is punctured. After the puncture is completed, the baffle 62 is opened, allowing the plastic bottle to fall, thereby preventing the plastic bottles from piling up on the upper end of the horizontal plate 8 and affecting the subsequent puncturing operation.

[0042] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
