Description

TECHNICAL FIELD

[0001] The present application relates to the field of plastic product recycling, in particular, to a classification device for plastic product recycling. BACKGROUND

[0002] Plastic bottles are mainly made of polyethylene or polypropylene and other materials and added with various organic solvents. Plastic bottles widely use polyester (PET), polyethylene (PE) and polypropylene (PP) as raw materials, and after adding corresponding organic solvents, they are heated at high temperature, and then are blown, extruded or injection molded into plastic containers through plastic molds. Plastic bottles are mainly used for beverage, food, pickles, honey, dried fruit, edible oil, agricultural and veterinary drugs, etc. Liquid or solid disposable plastic packaging containers. Plastic bottles have the characteristics of not easy to break, low cost, high transparency, food grade raw materials, etc.

[0003] For example, Chinese patent publication No. CN112008914A discloses a plastic bottle rapid classification and recycling device, which relates to the technical field of plastic bottle recycling. The plastic bottle rapid classification and recycling device comprises a box body, a movable door is rotatably connected to the front end face of the box body, a partition plate is fixedly connected to the inside of the box body, the inside of the box body is divided into a dry area and a wet area by the partition plate, the top of the dry area and the wet area are in communication with each other, a discharge pipe is fixedly connected to the lower surface of the box body and in communication with the dry area, a drainage pipe is also fixedly connected to the lower surface of the box body and in communication with the wet area, and a conveying mechanism is connected with the box body.

[0004] The existing technology has the following problems: when the liquid detector detects that there is no liquid in the corresponding plastic bottle, the controller makes the fan work, and the outlet of the air outlet pipe in the shell blows air flow. Due to the inclined upward arrangement of the air outlet pipe, the plastic bottle without liquid (i.e. the empty bottle with smaller mass) inside can be blown into the dry area under the action of the air flow. However, the distance between the partition plate and the air outlet pipe is far, and although the device can flatten the plastic bottles by the baffle, it cannot make the plastic bottles pass through the upper end of the air outlet pipe one by one, so that the plastic bottles without liquid can be blocked by the plastic bottles with liquid. In summary, the above-mentioned device may miss when separating dry and wet plastic bottles. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a classification device for plastic product recycling, which solves the problems raised in the background art.

[0006] In order to achieve the above object, the application provides a classification device for plastic product recycling, which comprises a processing box, a conveying box fixedly connected to the side of the processing box, and a lower hopper fixedly connected to the top of the processing box.

[0016] The application has the advantages that:

[0017] (1) The application combines a fan, a rotating rod, a swing frame, a shunt plate and other components to effectively realize dry-wet separation of plastic bottles. The shunt plate moves up and down to ensure that empty bottles and plastic bottles with liquid can pass through the upper end of the fan one by one without interfering with each other and having enough time to be blown by the fan, thereby ensuring that empty bottles and plastic bottles with liquid are guided to different areas to reduce the possibility of mis-sorting.

[0018] (2) The application sets a hole-punching assembly, uses a belt pulley, a transmission belt, a reciprocating wire rod and other components to realize automatic hole-punching operation. The coordinated action of the moving plate and the punching rod enables the plastic bottles to be automatically punctured to ensure that the liquid flows out, improves the efficiency, and the punctured plastic bottles can smoothly drain the liquid to prevent the liquid from polluting other areas and avoid the problem of liquid overflow or loss during the processing.

[0019] (3) The application sets a material removing assembly, uses a guide rail, a baffle, a gear ring, a pawl and other mechanisms to efficiently remove the punctured plastic bottles.

Vent holes are arranged at the positions where the conveying belt 41 and the lower end of the conveying box 2 are connected with the fan 42. A sliding groove 413 is arranged on the outer wall of the conveying box 2, and the connecting rod 410 is slidingly connected to the sliding groove 413. A partition plate 7 is fixedly connected to the inner part of the processing box 1, which is used for separating the processing box 1 into different parts for placing plastic bottles of different types. The partition plate 7 is fixedly connected to a horizontal plate 8 on one side, the horizontal plate 8 is fixedly connected to a guide plate 10 on the upper end, a through hole is arranged in the middle of the horizontal plate 8, and a discharge port and a water outlet 9 are arranged at the bottom of the processing box 1. The processing box 1 is provided with a hole punching assembly 5 and a material removing assembly 6.

[0037] In use, first of all, the plastic bottle is placed in the lower hopper 3, and then the plastic bottle will pass through the lower hopper 3 into the inside of the transport box 2, and then the transport belt 41 is started to drive the plastic bottle to move towards the processing box 1, and at the same time, the fan 42 is started to blow air from the outlet to the upper end, at this time, under the blowing of the air force, the rotating rod 44 will be rotated by the leaf plate 412, when the rotating rod 44 rotates, the rotating block 45 will 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, and at the same time, the sliding shaft 46 will slide in the inside of the swing frame 49, since the height of the sliding shaft 46 will change when rotating, the swing frame 49 will rotate around the rotating shaft 47, and then the swing block 48 on the outer wall of the rotating shaft 47 will swing, and then the two connecting rods 410 hinged on the upper end of the swing block 48 will present a rising and falling motion track, and then the two baffle plates 411 fixedly connected at the other end of the two connecting rods 410 will also rise and fall, and then the two baffle plates 411 can make the plastic bottle 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, since its mass is lighter, the fan 42 will blow it up, and then the empty plastic bottle will be blown to between the two clamping transport belts 43, when the empty plastic bottle contacts the clamping transport belts 43, the two clamping transport belts 43 will clamp the empty plastic bottle to transport it to the inside of the processing box 1 and drop to the right side of the partition plate 7, and then be crushed by the crushing roller, and the plastic bottle containing liquid will not be blown up due to its heavier mass, and then be transported to the left side of the partition plate 7 in the processing box 1.

[0038] Embodiment 2, please refer to Figures 1-7 On the basis of embodiment 1, the perforating assembly 5 comprises a belt pulley A51 fixedly sleeved on the outer wall of the rotating rod 44, a transmission belt 52 wound around the outer wall of the rotating rod 44, a belt pulley B53 transmissionally connected to the other end of the transmission belt 52, a reciprocating screw rod 55 fixedly connected to the outer wall of the belt pulley B53, a fixed block 54 fixedly connected to the outer wall of the processing box 1, the reciprocating screw rod 55 being rotationally connected with the fixed block 54, a moving rod 56 threadedly connected to the outer wall of the reciprocating screw rod 55, a moving plate 57 fixedly connected to the side surface of the moving rod 56, and a perforating rod 58 fixedly connected to the surface of the moving plate 57. A fixed shaft 59 is fixedly connected to the inner wall of the processing box 1, a push block 510 is fixedly connected to the other end of the fixed shaft 59, a through slot 511 is formed in the outer wall of the moving plate 57, an activity slot A512 is formed in the side surface of the processing box 1, and the moving rod 56 is slidably connected with the activity slot A512.

[0039] In use, when a plastic bottle containing liquid falls to the left side of the processing box 1, it will slide down onto 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, its external pulley A51 will also rotate. Under the transmission action of the transmission belt 52, it will drive the pulley B53 to rotate. The pulley B53 will then drive the reciprocating screw 55 to rotate. Consequently, the moving rod 56, which is threaded to the outside of the reciprocating screw 55, will move 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, which will cause the tie rod 58 on its outer wall to move toward the plastic bottle, thereby breaking the plastic bottle and causing the liquid in the plastic bottle to flow out. When the movable plate 57 returns to its original position along with the movable rod 56, the fixed shaft 59 fixed to the inner wall of the processing box 1 and the push 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 position, the push block 510 will push out the plastic bottle stuck on the outer wall of the tie rod 58, causing the plastic bottle to fall to the upper end of the baffle 62.

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

[0041] When the plastic bottle is pierced, the liquid inside the bottle will flow through the filter hole 610 at the upper end of the baffle 62 to the inside of the processing box 1, and then be discharged from the processing box 1 through the water outlet 9. When the moving rod 56 moves, the toothed plate 611 will move, and the toothed plate 611 will drive the gear ring 64 to rotate. When the toothed plate 611 moves to the middle of the processing box 1, the gear ring 64 rotates clockwise, and the gear ring 64 will not drive the ratchet wheel 65 to rotate through the internal pawl 68. When the moving rod 56 moves to the edge of the processing box 1, the toothed plate 611 will drive the gear ring 64 to rotate counterclockwise, and the gear ring 64 will drive the ratchet wheel 65 to rotate through the internal pawl 68. Then the ratchet wheel 65 will drive the push rod 67 to rotate through the connecting shaft 66. When the push rod 67 rotates and moves a distance, it will contact the stop block 63. Then when the push rod 67 continues to rotate, it will drive the baffle 62 to slide on the outer wall of the guide rail 61 by pushing the stop block 63. Then the baffle 62 will open the through hole in the middle of the horizontal plate 8, and the pierced plastic bottle will fall to the bottom of the processing box 1. When the push rod 67 rotates to a certain angle, it will be separated from the stop block 63. Then under the action of the tension spring 69, the baffle 62 will quickly reset, thereby ensuring that the baffle 62 is closed before the plastic bottle containing liquid is pierced, and the baffle 62 is opened after the piercing is completed, so that the plastic bottle falls, thereby avoiding the accumulation of plastic bottles on the upper end of the horizontal plate 8, which affects the subsequent piercing operation.

[0042] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacements or changes to the technical solution and the inventive concept of the present application within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
