[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments

[0029] Refer to Figures 1-8 , a high-efficiency bottle brick unpacking device for recycling waste plastic bottles, including an inner frame 3 and a conveyor belt 7 arranged on the inner frame 3. A frame 1 is fixedly installed on the outside of the inner frame 3. The frame 1 is used to support the inner frame 3 and the conveyor belt 7. A baffle 4 is arranged at one end of the inner frame 3, and the end with the baffle 4 is the front end. A magnetic adsorption transfer belt 6 is rotatably installed at the other end of the inner frame 3. The magnetic adsorption transfer belt 6 is arranged above the conveyor belt 7, and a guiding plate 5 is arranged on the upper surface of the magnetic adsorption transfer belt 6

[0030] On both sides of one end of the frame 1 close to the baffle 4, L-shaped rotating frames 8 are symmetrically and rotatably installed. Hooks 11 are movably installed below the upper ends of the two L-shaped rotating frames 8. Driving cylinders 36 for driving the L-shaped rotating frames 8 to rotate are rotatably installed on both sides of the frame 1. The driving end of the driving cylinder 36 is fixedly connected with a telescopic shaft 16, and the telescopic shaft 16 is rotatably connected to the surface of the L-shaped rotating frame 8

[0031] A dispersion mechanism 10 is arranged on one side of the conveyor belt 7 away from the L-shaped rotating frame 8. A plurality of hammer shafts 13 are arranged below the dispersion mechanism 10. A hammer block 25 is arranged at the lower end of each hammer shaft 13. The dispersion mechanism 10 is used to drive each hammer shaft 13 to move up and down to strike the bottle brick through the hammer block 25

[0032] The conveyor belt 7 is rotatably mounted in the frame 1 through the belt shaft 14. A first motor 15 is provided on the frame 1. The first motor 15 is fixedly connected to one of the belt shafts 14 through the drive end. The inner frame 3 passes through the inside of the conveyor belt 7. A collection groove 37 is provided at the bottom of the inner frame 3. The collection groove 37 is arranged inside the conveyor belt 7. The upper surface of the collection groove 37 forms a hollow structure by opening a slot 24. The lower surface of the collection groove 37 is an inclined surface. An outlet 2 is opened on one side of the frame 1. One side of the collection groove 37 is an opening, and the opening is communicated with the outlet 2. The conveyor belt 7 is a grid hollow structure. When the bottle bricks are transported on the surface of the conveyor belt 7, the impurities mixed therein will fall downward along the gaps in the grid, and then fall into the collection groove 37 through the slot 24, and slide downward along the inclined surface in the collection groove 37, and finally be output through the outlet 2. Thus, during the conveying process, small particle impurities are screened out for cleaning.

[0033] A bag cutting mechanism 12 is arranged on one side of the L-shaped rotating frame 8 on the conveyor belt 7. The bag cutting mechanism 12 is used for cutting the wrapping of the bottle bricks. The bag cutting mechanism 12 includes a cutting knife 18, a threaded rod 22 and an L-shaped rod 21. The lower end of the L-shaped rod 21 is fixedly connected to the inner wall of the inner frame 3. The threaded rod 22 is rotatably mounted on one side of the L-shaped rod 21. A slider 23 is slidably sleeved on the L-shaped rod 21. The slider 23 is also threadedly sleeved on the threaded rod 22. The cutting knife 18 is fixedly installed on the side of the slider 23 close to the L-shaped rotating frame 8. A heating wire is arranged on the surface of the cutting knife 18. The upper end of the L-shaped rod 21 is fixedly installed with a second motor 19. The drive end of the second motor 19 is fixedly connected to the upper end of the threaded rod 22. When the wrapping of the bottle bricks is hooked on the L-shaped rotating frame 8, the wrapping will approach the cutting knife 18. The cutting knife 18 can be heated through the heating wire. When it contacts the surface of the wrapping, it can effectively cut it. At the same time, the second motor 19 rotates the threaded rod 22 through the drive end. As the threaded rod 22 rotates, the slider 23 can be driven to move up and down relative to the L-shaped rod 21, so that the cutting knife 18 can cut the wrapping from bottom to top to release the bottle bricks.

[0034] An arc-shaped shaft 17 is fixedly installed on the L-shaped rotating frame 8. The upper end of the hook 11 is slidably sleeved on the surface of the arc-shaped shaft 17. A U-shaped shaft is connected between the two L-shaped rotating frames 8. By connecting the two L-shaped rotating frames 8 through the U-shaped shaft, the two L-shaped rotating frames 8 can maintain the same relative angle. The hook 11 slides back and forth on the arc-shaped shaft 17, which is convenient for the operator to hook the wrapping of the bottle bricks on the hook 11.

[0035] The dispersion mechanism 10 includes a support 9 and a plurality of gears 32 rotatably mounted on the support 9. Two gears 32 on the same side are fixedly connected together by a linkage shaft 35. A worm gear 34 is fixedly sleeved on the linkage shaft 35. One end of the support 9 is rotatably connected to a rotating shaft 30. A worm 31 is provided on the rotating shaft 30. The worm 31 meshes with the worm gear 34. A third motor 29 for driving the rotation of the rotating shaft 30 is provided on the support 9. A connecting mechanism is provided on a plurality of hammer shafts 13. The gear 32 meshes with the connecting mechanism. The third motor 29 drives the rotating shaft 30 to rotate through the driving end. The rotating shaft 30 drives the worm 31 to rotate. The worm 31 meshes with the worm gear 34. The worm 31 drives the linkage shaft 35 to rotate through the worm gear 34. The linkage shaft 35 drives the gear 32 to rotate. The hammer shaft 13 meshes with the gear 32 through the connecting mechanism. Then, as the gear 32 rotates, the hammer shaft 13 can move up and down, and the bottle bricks are knocked and dispersed by the hammer block 25.

[0036] The connecting mechanism includes a plurality of rack plates 28. A plurality of hammer shafts 13 are connected in a row through a second connecting plate 26. A plurality of second connecting plates 26 are connected together through a first connecting plate 27 to form a plate. The rack plates 28 are fixedly installed on the first connecting plate 27. A plurality of rack plates 28 are arranged in the outer range of a plurality of gears 32. The gear 32 meshes with the inner surface of the rack plate 28. Each rack plate 28 meshes in the outer range of the gear 32. Each gear 32 can directly play a role in meshing and clamping and fixing each rack plate 28. A plurality of hammer shafts 13 are connected together through the second connecting plate 26 and the first connecting plate 27. When the gear 32 rotates, it can drive the rack plate 28 to move up and down, so that each hammer shaft 13 moves up and down.

[0037] A third motor 20 is fixedly installed on the inner frame 3. The third motor 20 drives the rotating rod to rotate through the driving end. The moving direction of the upper surface of the conveyor belt 7 is from the baffle 4 towards the dispersion mechanism 10. The moving direction of the lower surface of the magnetic adsorption conveyor belt 6 is opposite to the moving direction of the upper surface of the conveyor belt 7. The third motor 20 drives the rotating rod to rotate through the driving end, which can drive the magnetic adsorption conveyor belt 6 to move. When the magnetic adsorption conveyor belt 6 moves, it can adsorb the metal materials mixed in the bottle bricks. When the metal materials move from the lower part to the upper part of the magnetic adsorption conveyor belt 6, they will contact the guide plate 5. And as the magnetic adsorption conveyor belt 6 continues to move, the metal can be scraped onto the guide plate 5.

[0038] A plurality of limiting grooves 33 are provided on the support 9. The rack plate 28 is slidably clamped in the rack plate 28. The rack plate 28 slides up and down under the limiting action of the limiting groove 33 to stably reinforce the structure.

[0039] One end of the guide plate 5 is an inclined plate and the other end is a flat plate. The inclined plate contacts the surface of the magnetic adsorption conveyor belt 6. Magnets are installed on the surface of the guide plate 5, and the material of the guide plate 5 is magnetic metal. When the metal material contacts the guide plate 5, it will be squeezed onto the surface of the guide plate 5. At the same time, under the action of the magnets, the guide plate 5 can keep the pushed-up metal material stable.

[0040] In the initial state, the L-shaped rotating frame 8 will rotate under the action of the driving cylinder 36, so that the upper end of the L-shaped rotating frame 8 is outside the range of the conveyor belt 7. Place the bottle brick package to be unpacked at one end of the front baffle 4 of this device. The upper end of the L-shaped rotating frame 8 will turn to the front position. The staff slides the hook 11 and hooks it on both sides of the bottle brick package. The driving cylinder 36 then drives the telescopic shaft 16 at the driving end, thereby lifting the L-shaped rotating frame 8, so that the upper end of the L-shaped rotating frame 8 is lifted and moved above the conveyor belt 7.

[0041] After hanging the bottle brick package, the package is directly separated from the cutter 18. The second motor 19 drives the threaded rod 22 to rotate through the driving end. As the threaded rod 22 rotates, it can drive the slider 23 to move up and down relative to the L-shaped rod 21. The heated cutter 18 can cut the surface of the package from bottom to top, thereby releasing the packaged bottle bricks and achieving the unpacking effect.

[0042] The bottle bricks fall onto the conveyor belt 7, and the transportation effect is achieved as the conveyor belt 7 rotates. During the transportation process, the small particle impurities mixed in the bottle bricks will directly leak from the surface of the conveyor belt 7, and then leak into the collection tank 37 through the slot 24, slide down along the inclined surface of the inner wall of the collection tank 37, and finally output through one end of the outlet 2, realizing the filtration and collection of small particle dust impurities.

[0043] When the bottle bricks move below the hammer shaft 13, the third motor 29 drives the rotating shaft 30 to rotate through the driving end. The rotating shaft 30 drives the worm 31 to rotate. The worm 31 meshes with the worm gear 34. The worm gear 34 is fixedly installed on the linkage shaft 35. Therefore, the worm 31 drives the linkage shaft 35 to rotate through the worm gear 34. The linkage shaft 35 drives the gear 32 to rotate. The gear 32 meshes with the rack plate 28. As the gear 32 rotates, the rack plate 28 can move up and down. During the up and down movement of the rack plate 28, it will drive the hammer shaft 13 to move up and down, and the hammer block 25 can continuously strike the bottle bricks to disperse them. At the same time, an inner frame 3 is arranged inside the conveyor belt 7 to provide a supporting effect. Through the knocking and rolling effect of the hammer block 25, the attached bottle bricks can be effectively dispersed.

[0044] When the dispersed bottle bricks move below the magnetic adsorption transfer belt 6, since the surface of the magnetic adsorption transfer belt 6 has magnetism and has an adsorption effect on metal materials, the metal materials doped therein can be adsorbed and retained under the magnetic adsorption effect. And as the magnetic adsorption transfer belt 6 rotates itself, the adsorbed metal materials will be rotated to the upper position, and the adsorbed metal materials will eventually be pushed onto the surface of the guide plate 5, so as to separate the metal materials from the bottle bricks.

[0045] The unpacking of the bottle brick package by this device can achieve preliminary impurity cleaning and removal of metal materials, thus effectively reducing the operations in subsequent processing, improving work efficiency, and reducing the complexity of the project.

[0046] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
