[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. A plastic waste recycling device of the present invention has two crushing plates arranged above the filter, and both crushing plates are provided with crushing blocks staggered from each other. The crushing plates and the crushing blocks can be used to perform secondary crushing on the unfiltered waste plastic above the filter, so that the waste plastic can meet the size and fall through the filter, and there is no need to take out the unqualified waste plastic on the filter, which saves the time required for taking out the unqualified waste plastic and re-loading, saves time and labor, can effectively improve the efficiency and effect of the waste plastic crushing, and is conducive to the recycling of the waste plastic.

[0029] 2. A plastic waste recycling device of the present invention is provided with a first transmission component. When two crushing rollers crush the waste plastics, the first transmission component can drive the telescopic component to work while the crushing rollers rotate, so that the crushing plates on both sides can continuously approach and move away from each other, thereby realizing secondary crushing of unqualified waste plastics. That is, the first transmission component enables the crushing mechanism and the rolling mechanism to achieve a linkage effect, which is beneficial to reducing the number of driving sources used in the device, reducing power consumption, and further helping to reduce costs.

[0030] 3. A plastic waste recycling device of the present invention can play a shielding role by arranging a baffle between the crushing plate and the crushing roller. When the two crushing plates are close to each other, the two baffles can rotate upward under the action of the rotating component, and the ends of the two baffles close to each other are in contact with each other, which can play a shielding and isolating role, preventing the waste crushed by the crushing roller from falling on the side where the two crushing plates are far away from each other. When the two crushing plates are far away from each other, under the action of the rotating component, the baffle can rotate downward to achieve reset. In this process, the crushed waste plastics above the two baffles can fall between the two crushing plates under the guidance of the baffles, so as to facilitate the subsequent secondary crushing of the unqualified waste plastics filtered out.

[0031] 4. By setting up electromagnetic rods, the magnetic metal in the waste plastics can be adsorbed during the falling process, so as to achieve the impurity removal of the waste plastics. At the same time, the moving assembly can drive the two electromagnetic rods to move back and forth inside the box, so as to achieve uniform and comprehensive impurity removal of the waste materials in the falling process, avoid impurities in the waste plastics, affect the subsequent secondary recycling of the waste plastics, and help improve the quality of plastic products.

[0032] 5. By setting up a second transmission component, when the two crushing plates approach and move away from each other, the second transmission component can drive the moving component to work, so that the two electromagnetic rods can slide back and forth horizontally inside the box, that is, using a second transmission component, the rolling mechanism and the impurity removal mechanism can achieve a linkage effect, which can further reduce the number of driving sources used in the device, reduce power consumption, and thus help reduce power consumption and costs.

[0033] 6. By setting up a collection component, when a position sensor detects that an electromagnetic rod moves into a side box, the position sensor sends a signal to the controller, and the controller controls the electromagnetic rod to cut off power. At this time, the magnetic metal adsorbed on the electromagnetic rod will fall into the first collection box, thereby realizing the collection of the magnetic metal.

DETAILED DESCRIPTION

[0048] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0049] The present invention provides the following preferred embodiments:

[0050] Embodiment 1, as Figure 1-Figure 13As shown, a plastic waste recycling device includes a box body 11, a feed port 12 is installed at the top of the box body 11, and the feed port 12 is used to feed the waste plastics to be recycled so as to crush the waste plastics. It also includes a filter screen 16, a crushing mechanism, a rolling mechanism and a debris removal mechanism. The filter screen 16 is fixedly installed inside the box body 11. The filter screen 16 is used to screen the crushed waste plastics to ensure that the crushed waste plastics meet the required size, which is conducive to the subsequent recycling of the waste plastics. It should be noted here that in actual use, the filter screen 16 can adopt the linear vibrating screen in the prior art, which is conducive to improving the screening efficiency;

[0051] The crushing mechanism includes a driving assembly and two crushing rollers 13. The two crushing rollers 13 are symmetrically arranged at the top of the inner part of the box 11. The driving assembly is located between the box 11 and the two crushing rollers 13. Before the waste plastic needs to be crushed, the two crushing rollers 13 are first driven to rotate by the driving assembly. When the two crushing rollers 13 rotate, the crushing teeth on the crushing rollers 13 can crush the waste plastic. It should be noted that the rotation directions of the two crushing rollers 13 are opposite, and the crushing teeth on the two crushing rollers 13 are staggered.

[0052] The crushing mechanism includes a telescopic component, a first transmission component, two crushing plates 17, two baffles 54, two rotating components and a plurality of crushing blocks 18. The two crushing plates 17 are symmetrically slidably arranged on both sides above the filter screen 16. The plurality of crushing blocks 18 are respectively installed on the side where the two crushing plates 17 are close to each other. It should be noted here that the crushing blocks 18 on the two crushing plates 17 are staggered to improve the crushing effect of the waste plastics. The telescopic component is located between the two crushing plates 17. The telescopic component can drive the two crushing plates 17 to approach or move away from each other. When the two crushing plates 17 are close to each other, the crushing blocks 18 on the crushing plates 17 can be used to crush the unqualified waste plastics screened out at the middle position of the two crushing plates 17 again. When the two crushing plates 17 are away from each other, it is convenient to make the waste plastics crushed by the two crushing rollers 13 fall on the filter screen 16. The first transmission component is located between the telescopic component and one of the crushing rollers 13. Through the first transmission component, when the crushing roller 13 rotates to crush the waste plastics, the first transmission component can drive the telescopic component to work, so that the two crushing plates 17 can be moved, that is, The first transmission component enables the crushing mechanism and the rolling mechanism to achieve a linkage effect, which is beneficial to reducing the number of driving sources used in the device, reducing power consumption, and thus helping to reduce costs. Each baffle 54 is located at the top of a crushing plate 17, and the two baffles 54 are rotatably arranged on the box body 11 on the sides away from each other. Each rotating component is located between a crushing plate 17 and a baffle 54. By arranging the baffle 54 between the crushing plate 17 and the crushing roller 13, a shielding effect can be achieved. When the two crushing plates 17 are close to each other, the two baffles 54 can rotate upward under the action of the rotating assembly, and the ends of the two baffles 54 that are close to each other fit together, which can play a role of shielding and isolation, preventing the waste crushed by the crushing roller 13 from falling on the side where the two crushing plates 17 are away from each other. When the two crushing plates 17 are away from each other, under the action of the rotating assembly, the baffle 54 can rotate downward to achieve reset. In this process, the crushed waste plastics above the two baffles 54 can fall between the two crushing plates 17 under the guidance of the baffles 54, so as to facilitate the subsequent secondary crushing of the unqualified waste plastics filtered out;

[0053] The impurity removal mechanism includes a moving assembly, a second transmission assembly, two mounting plates 48, two electromagnetic rods 49 and two collecting assemblies. The two electromagnetic rods 49 are arranged in parallel, and each mounting plate 48 is installed between one end of two transmission belts 29. Each mounting plate 48 is slidably arranged on the inner wall of the box body 11. The moving assembly is located between the box body 11 and one of the mounting plates 48. The moving assembly is used to drive the mounting plate 48 to move, so that the electromagnetic rods 49 on the mounting plate 48 can be moved, and the magnetic metal in the waste plastic can be adsorbed during the falling process of the waste plastic, so as to remove impurities from the waste plastic. At the same time, the moving assembly can drive the two electromagnetic rods 49 to reciprocate inside the box body 11. The second transmission component is located between the moving component and the telescopic component. By setting the second transmission component, when the two crushing plates 17 approach and move away from each other, the moving component can be driven by the second transmission component, so that the two electromagnetic rods 49 can slide back and forth horizontally inside the box body 11, that is, a second transmission component is used to achieve a linkage effect between the crushing mechanism and the impurity removal mechanism, which can further reduce the number of driving sources used in the device and reduce power consumption, thereby helping to reduce power consumption and cost.

[0054] like Figure 1-Figure 13 As shown, each driving assembly includes a motor 15 and two first gears 14, one end of each crushing roller 13 passes through the box body 11 and is fixedly connected to a first gear 14, the two first gears 14 are meshed with each other, the motor 15 is installed on the box body 11, and the output end of the motor 15 is fixedly connected to one of the first gears 14. When in use, the motor 15 is first controlled to work, and the motor 15 can drive the first gear 14 connected to its output end to rotate. Since the two first gears 14 are meshed with each other, when one of the first gears 14 rotates, it can drive the other first gear 14 to rotate, so that the two first gears 14 can rotate at the same time, and then the two crushing rollers 13 can rotate at the same time, so as to realize the crushing of waste plastics.

[0055] like Figure 1-Figure 13 As shown, the first transmission assembly includes a driving wheel 27, a driven wheel 28, a transmission belt 29, a cam 30, a first tension wheel 31, a first mounting seat 32, a limit seat 33, a spring 34, a sliding rod 35, a second tension wheel 36 and a second mounting seat 58;

[0056] The cam 30 is rotatably arranged on one side of the box body 11, the limit seat 33 is located below the cam 30 and fixed on the box body 11, the sliding rod 35 is slidably arranged on the limit seat 33, the top end of the sliding rod 35 is fixedly connected to the first mounting seat 32, the first clamping wheel 31 is rotatably arranged on the first mounting seat 32, and the top end of the first clamping wheel 31 is in contact with the surface of the cam 30, the second mounting seat 58 is fixed to the bottom end of the sliding rod 35, the second clamping wheel 36 is rotatably arranged below the second mounting seat 58, the spring 34 is sleeved on the outside of the sliding rod 35, and the two ends of the spring 34 are respectively fixedly connected to the limit seat 33 and the second mounting seat 58;

[0057] The driven wheel 28 is located at one side of the cam 30 and is coaxially fixedly connected to the cam 30, that is, when the driven wheel 28 rotates, it can drive the cam 30 to rotate synchronously. One end of a crushing roller 13 away from the motor 15 passes through the box body 11 and is fixedly connected to the driving wheel 27. The transmission belt 29 is sleeved on the driving wheel 27 and the driven wheel 28.

[0058] In the initial state, the spring 34 is in a natural state. When the crushing roller 13 rotates, it can drive the driving wheel 27 to rotate. Under the action of the transmission belt 29, the driving wheel 27 can drive the driven wheel 28 to rotate synchronously while rotating. When the driven wheel 28 rotates, it can drive the cam 30 to rotate. When the cam 30 rotates, the cam 30 can press the first tensioning wheel 31, so that the first tensioning wheel 31 can move downward. At this time, the first tensioning wheel 31 drives the sliding rod 35 to slide downward on the limit seat 33 through the first mounting seat 32, and at the same time drives the second tensioning wheel 36 to move vertically downward. At this time, the spring 34 is stretched. As the cam 30 continues to rotate, under the action of the spring 34, the first tensioning wheel 31 moves upward and gradually resets. At the same time, the second tensioning wheel 36 also moves upward under the action of the spring 34 to achieve reset.

[0059] like Figure 1-Figure 13 As shown, the telescopic assembly includes a swing rod 25, two first strip grooves 26, two first insertion rods 24, two pulling plates 21, two moving plates 20 and a plurality of pull rods 19;

[0060] The middle part of the swing rod 25 is rotatably arranged on the surface of the box body 11 through the rotating shaft, and a return spring is sleeved on the rotating shaft. The two ends of the return spring are respectively abutted against the box body 11 and the swing rod 25, and the bottom end of the second clamping wheel 36 is abutted against the top of one side of the swing rod 25. When the second clamping wheel 36 moves vertically downward, it can push the swing rod 25 to rotate around the rotating shaft in the middle of the swing rod 25, so that the swing rod 25 can rotate clockwise. At this time, the return spring on the rotating shaft is deformed, and the two first strip grooves 26 are symmetrically arranged on both sides of the surface of the swing rod 25, and each first plug rod 24 is inserted into the inside of a first strip groove 26. The two pulling plates 21 are symmetrically slidably arranged on both sides of one end of the box body 11, and each first plug rod 24 is fixedly connected to a pulling plate 21. When the swing rod 25 rotates clockwise, the swing rod 25 drives the two first strip grooves 26 to rotate, so that the two pulling plates 21 can be driven to approach each other under the action of the two first plug rods 24;

[0061] Each movable plate 20 is fixed to one end of a pulling plate 21, and a plurality of pull rods 19 are symmetrically fixed to the sides of the two movable plates 20 that are close to each other. The plurality of pull rods 19 on each movable plate 20 pass through the box 11 and are fixedly connected to the side of a crushing plate 17 away from the crushing block 18, and the pull rods 19 are slidably connected to the box 11;

[0062] When the two pulling plates 21 are brought closer to each other, the two crushing plates 17 can be driven closer to each other through the moving plate 20 and the multiple pull rods 19, so that the multiple crushing blocks 18 on the two crushing plates 17 can crush the unqualified waste plastics screened out again;

[0063] Similarly, when the second abutting wheel 36 moves upward, the reset spring on the rotating shaft can drive the swing rod 25 to rotate in the opposite direction to achieve reset, so that the two crushing plates 17 can move away from each other to the initial position.

[0064] like Figure 1-Figure 13As shown, each rotating assembly includes two second plug rods 55 and two slots 56. The two slots 56 are symmetrically arranged on both sides of the baffle 54. Each second plug rod 55 is inserted into the inside of a slot 56. Each second plug rod 55 is fixed to the top of the crushing plate 17. When the two crushing plates 17 are close to each other, the crushing plate 17 can drive the two second plug rods 55 above the crushing plate 17 to move. Since the second plug rods 55 are inserted into the inside of the slots 56, when the second plug rods 55 move, they can drive the end of the baffle 54 away from the box body 11 to rotate upward. The ends of the two baffles 54 that are close to each other can touch each other, so that the waste plastics crushed by the crushing roller 13 can be received, and the waste materials crushed by the crushing roller 13 are prevented from falling on the side where the two crushing plates 17 are away from each other. When the two crushing plates 17 are away from each other, the baffles 54 can rotate downward to be reset with the cooperation of the second plug rod 55 and the slot 56. In this process, the crushed waste plastics above the two baffles 54 can fall between the two crushing plates 17 under the guidance of the baffles 54, so as to facilitate the subsequent secondary crushing of the unqualified waste plastics filtered out.

[0065] like Figure 1-Figure 13 As shown, a first guide block 23 is fixed to one side of each pulling plate 21 close to the box body 11, and two first guide grooves 22 are symmetrically provided on the surface of the box body 11. Each first guide block 23 is slidably arranged inside a first guide groove 22. By utilizing the sliding connection between the first guide block 23 and the first guide groove 22, the guiding effect of the pulling plate 21 can be achieved, thereby improving the stability of the pulling plate 21 when sliding.

[0066] like Figure 1-Figure 13 As shown, the second transmission assembly includes a sector rack 37, a second gear 38 and an L-shaped frame 40. The L-shaped frame 40 is fixed on the box body 11. The second gear 38 is rotatably set on the L-shaped frame 40. The sector rack 37 is fixedly mounted on one end of the swing rod 25. The sector rack 37 and the second gear 38 are meshed with each other. During the swinging process of the swing rod 25, the swing rod 25 can drive the sector rack 37 to rotate synchronously. Since the sector rack 37 and the second gear 38 are meshed with each other, when the sector rack 37 rotates, it can drive the second gear 38 to rotate.

[0067] like Figure 1-Figure 13As shown, the moving assembly includes a third gear 39, a bar rack 41, two guide rods 42, two fixing plates 43 and two second bar grooves 45. The two fixing plates 43 are symmetrically fixed on the surface of the box body 11. Each guide rod 42 is slidably set on a fixing plate 43. The bar rack 41 is fixed to one end of the two guide rods 42 close to each other. Through the sliding connection between the guide rod 42 and the fixing plate 43, the bar rack 41 can be guided and limited. The third gear 39 is located on one side of the L-shaped frame 40 and is coaxially fixedly connected with the second gear 38. When the second gear 38 rotates, it can drive the third gear 39 to rotate synchronously. The third gear 39 and the bar rack 41 are meshed with each other.

[0068] Two second strip grooves 45 are symmetrically provided on the inner walls at both ends of the box body 11, and each mounting plate 48 slides inside a second strip groove 45, and a through groove 57 connected to the second strip groove 45 is provided on one side of one of the second strip grooves 45, and a slider 47 is slidably provided inside the through groove 57, and one end of the slider 47 is fixedly connected to a mounting plate 48, and the other end of the slider 47 is connected to a connecting plate 44, and the other end of the connecting plate 44 is fixedly connected to the bar-shaped rack 41. Preferably, accordion protective covers 46 are fixed on both sides of the slider 47, and the other end of each accordion protective cover 46 is connected to the inner wall of the through groove 57. By providing the accordion protective cover 46, the inside of the through groove 57 can be shielded to prevent waste plastic from splashing out during the crushing process;

[0069] When the swing rod 25 rotates clockwise, it can drive the sector rack 37 to rotate, and the sector rack 37 drives the second gear 38 to rotate, and the second gear 38 drives the third gear 39 to rotate. Since the third gear 39 and the bar rack 41 are meshed with each other, the third gear 39 can drive the bar rack 41 to move horizontally when it rotates. The bar rack 41 can drive the slider 47 to slide inside the groove 57 through the connecting plate 44, thereby driving the mounting plate 48 to slide inside the second bar groove 45, realizing the movement of the two electromagnetic rods 49. At the same time, when the swing rod 25 rotates in the opposite direction, it can drive the two electromagnetic rods 49 to move in the opposite direction, so that the electromagnetic rods 49 can reciprocate inside the box body 11, realizing uniform and comprehensive impurity removal of waste materials in the falling process, avoiding impurities in the waste plastics, affecting the subsequent secondary recycling of the waste plastics, and helping to improve the quality of plastic products.

[0070] like Figure 1-Figure 13As shown, each collecting assembly includes a side box 51 and a first collecting box 52. The side box 51 is fixed to one side of the box body 11, and the side box 51 and the box body 11 are connected. The first collecting box 52 is fixed below the side box 51, and the first collecting box 52 and the side box 51 are connected. Preferably, a hinged door is provided below the first collecting box 52 to facilitate the removal of the magnetic metal stored in the first collecting box 52. Both ends of each second strip groove 45 extend to the inside of the two side boxes 51 on both sides. The inner walls of both ends of one of the second strip grooves 45 are provided with a position sensor 50. Specifically, the position sensor 50 is connected to the control The device is electrically connected. When one of the position sensors 50 detects that one end of the second strip groove 45 moves to a suitable position, a signal is sent to the controller. The controller controls the electromagnetic rod 49 close to the side of the position sensor 50 to cut off the power. At this time, the magnetic metal adsorbed on the electromagnetic rod 49 will fall into the first collection box 52. Similarly, the position sensor 50 on the other side can detect the position of the other end of the second strip groove 45, so that the other electromagnetic rod 49 can be powered off when it moves to a suitable position, so that the magnetic metal will fall into the other first collection box 52, thereby collecting the magnetic metal.

[0071] like Figure 1-Figure 13 As shown, a second collecting box 53 is provided at the bottom of the inner cavity of the box body 11. The second collecting box 53 is located below the two electromagnetic rods 49. The second collecting box 53 is slidably arranged inside the box body 11. The qualified waste plastics after crushing can be collected through the second collecting box 53. At the same time, the second collecting box 53 slides inside the box body 11, so that the second collecting box 53 and the waste plastics inside the second collecting box 53 can be taken out conveniently.

[0072] The specific working process of the present invention is as follows:

[0073] First, the motor 15 is controlled to work, and the motor 15 can drive the first gear 14 connected to the output end thereof to rotate. Since the two first gears 14 are meshed with each other, when one of the first gears 14 rotates, the other first gear 14 can be driven to rotate, so that the two first gears 14 can rotate at the same time, and then the two crushing rollers 13 can rotate at the same time, and the waste plastics to be crushed are placed inside the feed port 12 to achieve the crushing of the waste plastics; the crushed waste plastics fall downward, and the crushed plastics can be screened under the action of the filter screen 16, and the qualified waste plastics fall into the inside of the second collection box 53 for collection, and the unqualified waste plastics are left above the filter screen 16;

[0074] When the crushing roller 13 rotates, it can drive the driving wheel 27 to rotate. Under the action of the transmission belt 29, the driving wheel 27 can drive the driven wheel 28 to rotate synchronously while rotating. When the driven wheel 28 rotates, it can drive the cam 30 to rotate. When the cam 30 rotates, the cam 30 can press the first tension wheel 31, so that the first tension wheel 31 can move downward. At this time, the first tension wheel 31 drives the sliding rod 35 to slide downward on the limiting seat 33 through the first mounting seat 32, and at the same time drives the second tension wheel 36 to move vertically downward. At this time, the spring 34 is stretched. When the second tension wheel 36 moves vertically downward When moving, the swing rod 25 can be pushed to rotate around the rotation axis in the middle of the swing rod 25, so that the swing rod 25 can rotate clockwise. At this time, the return spring on the rotation axis is deformed. When the swing rod 25 rotates clockwise, the swing rod 25 drives the two first strip grooves 26 to rotate, so that the two pulling plates 21 can be driven to approach each other under the action of the two first insertion rods 24. When the two pulling plates 21 are close to each other, the two crushing plates 17 can be driven to approach each other through the moving plate 20 and the multiple pull rods 19, so that the multiple crushing blocks 18 on the two crushing plates 17 can crush the unqualified waste plastics screened out again;

[0075] As the cam 30 continues to rotate, under the action of the spring 34, the first abutting wheel 31 moves upward and gradually resets, and at the same time, the second abutting wheel 36 also moves upward under the action of the spring 34 to achieve reset. When the second abutting wheel 36 moves upward, under the action of the reset spring on the rotating shaft, the swing rod 25 can be driven to rotate in the opposite direction to achieve reset, so that the two crushing plates 17 can move away from each other to the initial position;

[0076] When the two crushing plates 17 are close to each other, the crushing plates 17 can drive the two second plug rods 55 above the crushing plates 17 to move. Since the second plug rods 55 are inserted into the slots 56, when the second plug rods 55 move, the end of the baffle plate 54 away from the box body 11 can be driven to rotate upward, so that the ends of the two baffle plates 54 close to each other can contact each other, so that the waste plastics crushed by the crushing rollers 13 can be received, and the waste materials crushed by the crushing rollers 13 are prevented from falling on the side where the two crushing plates 17 are away from each other. When the two crushing plates 17 are away from each other, under the cooperation of the second plug rods 55 and the slots 56, the baffle plates 54 can rotate downward to be reset. In this process, the crushed waste plastics above the two baffle plates 54 can fall between the two crushing plates 17 under the guidance of the baffle plates 54, so as to facilitate the subsequent secondary crushing of the unqualified waste plastics filtered out.

[0077] When the swing rod 25 rotates clockwise, it can drive the sector rack 37 to rotate, and the sector rack 37 drives the second gear 38 to rotate, and the second gear 38 drives the third gear 39 to rotate. Since the third gear 39 and the bar rack 41 are meshed with each other, the third gear 39 can drive the bar rack 41 to move horizontally when it rotates. The bar rack 41 can drive the slider 47 to slide inside the through groove 57 through the connecting plate 44, thereby driving the mounting plate 48 to slide inside the second bar groove 45, so as to realize the movement of the two electromagnetic rods 49. When one of the position sensors 50 detects that one end of the second bar groove 45 moves to a suitable position, a signal is sent to the controller, and the controller controls the electromagnetic rod 49 close to the side of the position sensor 50 to cut off the power. At this time, the magnetic metal adsorbed on the electromagnetic rod 49 will fall into the first collection box 52, so as to realize the collection of the magnetic metal.

[0078] At the same time, when the pendulum rod 25 rotates in the opposite direction, it can drive the two electromagnetic rods 49 to move in the opposite direction. The position sensor 50 on the other side can detect the position of the other end of the second strip groove 45, so that the other electromagnetic rod 49 can be powered off when it moves to the appropriate position, so that the magnetic metal will fall into the inside of the other first collection box 52, thereby collecting the magnetic metal.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
