Technical Field

[0001] The invention relates to the technical field of plastic bottle recycling, in particular to a plastic bottle high-efficiency recycling device. Background Art

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with a variety of organic solvents added. Plastic bottles are mostly used for beverage packaging due to their characteristics of being difficult to break, low cost, high transparency, and food-grade raw materials. However, after people drink, most of the discarded plastic bottles are thrown into the trash can, and then the plastic bottles are recycled. The recycling of plastic bottles mainly includes sorting, crushing, cleaning and other processes, among which the crushing of plastic bottles is the key to the recycling value of plastic bottles.

[0003] At present, there are certain deficiencies in crushing plastic bottles by crushing machines, such as: 1. Some plastic bottles are in a sealed state because the bottle caps are not removed. They have strong pressure resistance and are not easy to deform. They are easy to slip between the crushing rollers during crushing, resulting in failure to be crushed; 2. Since plastic bottles are light in texture, they may be placed on one side of the crushing box when entering the crushing box, and cannot enter well between the two crushing rollers. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a highly efficient plastic bottle recycling device to solve the problem of full plastic bottles slipping during crushing.

[0026] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0027] Please refer to Figure 1-Figure 8As shown, a highly efficient plastic bottle recycling device comprises a conveying mechanism 1, a frame 2 and a receiving box 3. The conveying mechanism 1 is placed on one side of the frame 2, and the conveying mechanism 1 is tilted. A crushing box 5 is installed on the upper surface of the frame 2, and a hopper 6 is arranged on the top of the crushing box 5. The top of the hopper 6 is open, larger at the top and smaller at the bottom, so as to expand the receiving area and prevent the plastic bottles from falling to the outside of the machine body. The output end of the conveying mechanism 1 is placed above the hopper 6, and the plastic bottles transported by the conveying mechanism 1 will automatically fall into the hopper 6. The receiving box 3 is placed on the side of the frame 2 away from the conveying mechanism 1. A discharge guide cylinder 7 is arranged at the bottom of the crushing box 5, and the discharge guide cylinder 7 is placed above the receiving box 3. The crushed plastic will fall into the receiving box 3. The receiving box 3 is placed on the outside of the frame 2 to facilitate its movement. The end of the discharge guide cylinder 7 can also be placed above the cleaning pool to facilitate the cleaning of the crushed material. Crushing rollers 501 are symmetrically installed inside the crushing box 5 for rotation. The ends of the two crushing rollers 501 are provided with gears that mesh with each other so that the two crushing rollers 501 rotate in opposite directions. A driving motor 4 is fixed to one side of the frame 2. The output end of the driving motor 4 is connected to the end of one of the crushing rollers 501 through a belt. Guide blocks 502 are evenly arranged on both sides of the crushing box 5. The guide blocks 502 and the crushing teeth on the surface of the crushing rollers 501 are staggered to ensure that the plastic bottles can only fall between the two crushing rollers 501. The upper side of the guide blocks 502 that are close to each other is provided with an inclined surface 503 to guide the plastic bottles and move them to the center of the equipment.

[0028] Please refer to Figure 5-Figure 8 As shown, a rotating shaft 504 is rotatably installed between two adjacent guide blocks 502, and the rotating shaft 504 is placed on a side close to the crushing roller 501. A toggle plate 505 is arranged on the upper surface of the rotating shaft 504, and the toggle plate 505 is flush with the inclined surface 503. The so-called flush is the return state of the toggle plate 505. When the rotating shaft 504 rotates, the toggle plate 505 can exceed the inclined surface 503 to squeeze the plastic bottles on its surface. An arc plate 506 extends backward from the end of the toggle plate 505. The arc plate 506 and the arc center are concentric with the rotating shaft 504. The rotation amplitude of the toggle plate 505 is smaller than the angle between the two ends of the arc plate 506, so that the arc plate 506 is always placed between the two guide blocks during the working process. The inner side of 502 is prevented from having a plastic bottle entering between the two guide blocks 502 and hindering the return of the toggle plate 505. A lower extension plate 507 is arranged at the bottom of the rotating shaft 504. The lower extension plate 507 and the toggle plate 505 are fixed at an angle so that the two can rotate synchronously. A notch groove 508 is arranged on the surface of the lower extension plate 507. The bottom of the notch groove 508 is open. A connecting block 509 is arranged between the two guide blocks 502. A sliding rod 510 slides through the surface of the connecting block 509. An I-head 511 is arranged at the end of the sliding rod 510. The I-head 511 is stuck in the notch groove 508. At this time, controlling the sliding of the sliding rod 510 can control the toggle plate 505 to swing.

[0029] Please refer to Figure 6-Figure 8 As shown, a roller seat 512 is provided at one end of the slide bar 510 away from the I-head 511, and the cross-sectional size of the roller seat 512 is larger than that of the slide bar 510. The roller seat 512 is placed outside the crushing box 5, and a roller is provided at the end of the roller seat 512. A spring 513 is sleeved on the surface of the slide bar 510, and one end of the spring 513 is in contact with the outer surface of the crushing box 5, and the other end of the spring 513 is in contact with the roller seat 512. The elastic force of the spring 513 is utilized to ensure that the slide bar 510 is always subjected to an outward force, so that the toggle plate 505 is in a return state when no force is applied.

[0030] Among them, mounting plates 514 are symmetrically arranged on both sides of the crushing box 5, and the mounting plates 514 extend beyond the side surface of the crushing box 5. A control shaft 515 is rotatably installed between the two mounting plates 514 on the same side. The control shaft 515 is parallel to the axis of the crushing roller 501. The ends of the two control shafts 515 are connected to the ends of the crushing roller 501 by belt drive, thereby realizing synchronous movement. Cams 516 are evenly arranged on the surface of the control shaft 515, and the rollers at the ends of the roller seats 512 are in contact with the surfaces of the cams 516. The rollers are squeezed by the rotation of the cams 516 to realize the reciprocating movement of the slide bar 510.

[0031] Please refer to Figure 1-Figure 3 As shown, a vertical plate 102 is symmetrically and vertically arranged on one side of the frame 2 close to the conveying mechanism 1, a conveyor belt 101 is arranged on the inner side of the conveying mechanism 1, and a slide groove 103 is opened above the surface of the two vertical plates 102, and the slide groove 103 is opened vertically. A lifting plate 104 is slidably installed between the two slide grooves 103, and limit blocks 106 are symmetrically arranged at both ends of the lifting plate 104 so that the lifting plate 104 can only slide back and forth up and down, and the limit blocks 106 are placed on the outer side of the vertical plate 102. Puncture needles 105 are evenly arranged on the lower surface of the lifting plate 104. When the lifting plate 104 moves downward, the puncture needles 105 can puncture the plastic bottles passing below to achieve deflation, so that the plastic bottles can be deformed when squeezed.

[0032] Please refer to Figure 1 and Figure 3 As shown, turntables 108 coaxially connected to the rolling axis of the conveyor belt 101 are arranged on the upper sides of the conveying mechanism 1, so that the turntable 108 and the conveyor belt 101 rotate synchronously, an eccentric bolt 109 is arranged on the outer side of the turntable 108, a fixed bolt 107 is arranged at the outer center of the limit block 106, and a connecting rod 110 is rotatably installed on the surface of the fixed bolt 107, and the end of the connecting rod 110 away from the fixed bolt 107 is hinged on the eccentric bolt 109, and the lifting plate 104 is driven to reciprocate up and down through the connecting rod 110.

[0033] Among them, a cross bar 111 is fixed between the two vertical plates 102. The cross bar 111 is suspended above the conveyor belt 101 and is placed below the lifting plate 104. A hollow groove 112 is opened on the surface of the cross bar 111. The puncture needle 105 passes through the hollow groove 112, so that when the puncture needle 105 moves back to its position, it can block the plastic bottle attached to its surface to prevent the plastic bottle from moving up with it. The distance between the cross bar 111 and the surface of the conveyor belt 101 is greater than the plastic bottle to prevent blockage.

[0034] Working principle: The discarded plastic bottles are transported upward through the conveyor belt 101 and fall into the hopper 6. Then, they are crushed by the crushing roller 501 inside the crushing box 5. The crushed materials enter the receiving box 3 through the guidance of the discharge guide cylinder 7. During the crushing process, the crushing roller 501 will rotate at a high speed, and then drive the control shaft 515 to rotate through the belt drive. The rotation of the control shaft 515 can drive the rotation of multiple cams 516 on the surface. Due to the existence of the spring 513, the roller at the end of the roller seat 512 is always aligned with the surface of the cam 516. The surfaces are in contact with each other, and then during the rotation process, the slide bar 510 can be driven to move back and forth, and then the lower extension plate 507 is driven to swing through the cooperation of the I-head 511 and the notch groove 508, and then the toggle plate 505 is driven to swing to toggle the bottle toward the center. At the same time, when the conveying mechanism 1 conveys materials, the turntable 108 can be driven to rotate, and then the lifting plate 104 can be driven to move back and forth up and down through the eccentric bolt 109, so that the puncture needle 105 can pass through the hollow groove 112 to puncture the plastic bottle passing below, so as to facilitate the subsequent crushing work.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
