DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 9As shown, the present invention provides a technical solution: a plastic bottle recycling device, comprising a workbench 1, a movable plate 2 is symmetrically arranged on the top of the workbench 1, a plurality of puncturing cones 3 are fixedly connected to the surfaces of the two movable plates 2 that are close to each other, a puncturing component for driving the two movable plates 2 to move closer to or away from each other is arranged at the bottom of the two puncturing cones 3, stacking plates 4 are symmetrically arranged above the workbench 1, a plurality of circular holes 5 are opened on the inner walls of the two stacking plates 4, the puncturing cones 3 and the circular holes 5 correspond to and fit each other, plastic bottles 35 are stacked in the stacking area formed between the two stacking plates 4, a placing table 6 is attached to the bottom of the two stacking plates 4, one side of the two placing tables 6 is attached to each other, and a pulling component for driving the two placing tables 6 to move closer to or away from each other is arranged on the outside of the two placing tables 6.

[0033] During operation: multiple plastic bottles 35 that need to be recycled are stacked in the gap formed between the two stacking plates 4, and multiple plastic bottles 35 will be stacked above the placement table 6. Then the puncture component is started to make the two movable plates 2 move closer to each other. During the movement, the sides of the two movable plates 2 will gradually fit with the two stacking plates 4. At this time, several puncture cones 3 will first penetrate into the inner wall of the circular hole 5, and gradually penetrate into the plastic bottles 35 in the gap between the two stacking plates 4 to puncture the surface of the plastic bottle 35. After the outer wall of the plastic bottle 35 is punctured, the two movable plates 2 are moved away from each other for reset through the puncture component. During the reset process, the pulling component will be driven to move through the linkage component, and the pulling component will make the two placement tables 6 that are fitted together move away from each other. During the movement, multiple plastic bottles 35 stacked on the top of the placement table 6 The plastic bottles 35 will continuously fall downward and leave the stacking area formed by the two stacking plates 4, and after the two movable plates 2 are reset, the two placement tables 6 can also be re-attached together by pulling the assembly away, so that the stacking area above the placement table 6 can be restacked with a new batch of plastic bottles 35 that need to be processed. Through the above embodiment, multiple plastic bottles 35 can be punctured at the same time, and multiple piercings will appear on the outer wall surface of the plastic bottle 35 after puncturing. The water permeability of the inner and outer surfaces of the punctured plastic bottle 35 is enhanced, and the cleaning liquid can more easily penetrate into the interior and every corner of the bottle, thereby more effectively removing stains, residues and pollutants, and the puncturing assembly drives the pulling assembly to move when resetting, and the punctured plastic bottle 35 can be quickly taken out and wait for cleaning, which improves work efficiency and solves the problem that the plastic bottles 35 are difficult to take out when stacked between the two stacking plates 4.

[0034] like Figures 2 to 4As shown, the puncture assembly includes two inner slides 7, and the two inner slides 7 are fixedly installed on the top of the workbench 1. The inner walls of the two inner slides 7 are rotatably connected with bidirectional threaded rods 9, and the outer walls at both ends of the two bidirectional threaded rods 9 are threadedly connected with inner slides 8. The two inner slides 8 are respectively fixedly connected to the bottom of the two movable plates 2, and a driving assembly is arranged on one side of the two bidirectional threaded rods 9, and the driving assembly is used to drive the two bidirectional threaded rods 9 to rotate.

[0035] When working: start the driving assembly, the two bidirectional threaded rods 9 will rotate. During the rotation of the bidirectional threaded rods 9, since the threads on both sides of the bidirectional threaded rods 9 are in opposite directions, the two inner sliders 8 will be driven to slide close to each other inside the bidirectional threaded rods 9. The two inner sliders 8 will drive the two moving plates 2 to move close to each other, thereby driving the two groups of puncturing cones 3 to move close to each other, thereby achieving the effect of puncturing the plastic bottles 35 stacked between the two stacking plates 4.

[0036] like Figure 3 to Figure 4 As shown, the driving assembly includes a motor 12, which is fixedly installed on the top of the workbench 1. The motor 12 is fixedly connected to one side of one of the two-way threaded rods 9. The other sides of the two two-way threaded rods 9 are fixedly connected with a transmission ring 10, and a transmission belt 11 is transmission-connected between the outer walls of the two transmission rings 10.

[0037] When working: start the motor 12, its output shaft will drive one of the two-way threaded rods 9 to rotate, and drive the other two-way threaded rod 9 to rotate through the transmission relationship between the transmission ring 10 connected to one end of the two-way threaded rod 9 and the transmission belt 11, thereby achieving the effect of driving the two two-way threaded rods 9 to rotate. The two two-way threaded rods 9 rotate at the same time, thereby achieving the effect of driving the two movable plates 2 to move closer to or away from each other.

[0038] like Figures 6 to 8 As shown, the pulling assembly includes a plurality of horizontal platform 19, and every two horizontal platform 19 are respectively fixedly connected to the two sides of the two placing platforms 6, and the inner walls of the plurality of horizontal platform 19 are provided with opening grooves 20, and the two sides of the two movable plates 2 are fixedly connected with receiving plates 21, and the inner walls of the receiving plates 21 are plugged with plug-in rods 22, and the bottoms of the plug-in rods 22 are fixedly connected with cover plates 23, and the bottoms of the cover plates 23 are fixedly connected with magnet blocks 24, and the magnet blocks 24 are located directly above the horizontal platform 19, and a magnetic component for driving the magnet blocks 24 to rise or fall is arranged below the horizontal platform 19.

[0039] During operation: when the two movable plates 2 approach each other for puncturing, the movable plate 2 will drive the magnet block 24 to slide along the upper surface of the horizontal plate platform 19 through the receiving plate 21. When the movable plate 2 is attached to the stacking plate 4 to complete the puncturing, the magnet block 24 is located directly above the opening groove 20, and the magnet block 24 is lowered to the inside of the opening groove 20 through the magnetic component. When the two movable plates 2 move away from each other for resetting, since the magnet block 24 enters the inside of the opening groove 20, the two movable plates 2 will respectively drive the two horizontal plate platforms 19 to move away from each other during resetting. Therefore, during the resetting process of the two movable plates 2, the two placing platforms 6 will be driven to move away from each other, so that the plastic bottle 35 located between the two stacking plates 4 falls downward, thereby achieving the effect of being able to take out the punctured plastic bottle 35.

[0040] like Figures 7 and 8 As shown, the magnetic assembly includes a mounting platform 25, which is fixedly mounted on the top of the workbench 1. A magnet block three 27 is fixedly mounted above the mounting platform 25. The magnet block three 27 is located directly below the magnet block one 24, and the magnetic properties of the surfaces of the magnet block three 27 and the magnet block one 24 that are close to each other are of opposite polarities.

[0041] During operation: when magnet block 24 moves to the top of opening slot 20, since the magnetism of the surfaces of magnet block 3 27 and magnet block 24 that are close to each other are of opposite polarities, and magnet block 24 will no longer be blocked by horizontal plate 19, magnet block 24 will be attracted by magnet block 3 27 to enter the interior of opening slot 20, and restricted by cover plate 23, magnet block 24 will only drop into the interior of opening slot 20. When magnet block 24 drops into the interior of opening slot 20, cover plate 23 fits into the upper surface of horizontal plate 19, and when movable plate 2 is reset, magnet block 24 can always be attracted by magnet block 3 27 and located inside opening slot 20, so it can pull the two placement platforms 6 to move away from each other, thereby achieving the effect of plastic bottle 35 falling.

[0042] like Figures 7 and 8 As shown, a magnet block 26 is fixedly installed above the mounting platform 25. The magnet block 26 is located on one side of the magnet block 3 27. The magnet block 26 is located directly below the magnet block 1 24. The magnetic properties of the surfaces of the magnet block 26 and the magnet block 1 24 that are close to each other are of the same polarity. A reset spring 29 is arranged on the outside of the plug-in rod 22. The two ends of the reset spring 29 are respectively fixedly connected to the bottom of the receiving plate 21 and the top of the cover plate 23. The top of the plug-in rod 22 is fixedly connected to a limiting sleeve 230.

[0043] During operation: when magnet block 124 enters the interior of the opening groove 20 and drives the horizontal plate platform 19 to move, when magnet block 124 is reset to its original position, magnet block 124 is just located above magnet block 26. At this time, since the magnetic properties of the surfaces of magnet block 26 and magnet block 124 that are close to each other are of the same polarity, magnet block 26 will generate a repulsive force, causing magnet block 124 to generate an upward moving force, and cooperate with the rebound effect of reset spring 29 to cause magnet block 124 to move upward out of the interior of the opening groove 20, so that the two placement platforms 6 can be merged again after being separated, so that a new batch of plastic bottles 35 can be stacked above the placement platform 6.

[0044] like Figures 5 and 6 As shown, the bottoms of the two placement tables 6 are fixedly connected with inner sliding blocks 14, and the top of the workbench 1 is symmetrically fixedly installed with inner sliding seats 15. The inner sliding blocks 14 and the inner sliding seats 15 are slidably connected and adapted to each other. One end of the inner sliding block 14 is fixedly connected with a plug-in rod 16, and the plug-in rod 16 is plugged into the inner wall of the inner sliding seat 15. A return spring 17 is fixedly connected between one end of the inner sliding block 14 and the inner side surface of the inner sliding seat 15, and one end of the plug-in rod 16 is fixedly connected with a limiting sleeve 18.

[0045] During operation: when the pulling assembly drives the two placement tables 6 to move away from each other, the inner sliding block 14 connected to the bottom of the placement table 6 will move inside the inner sliding seat 15. During the movement, the inner sliding block 14 will squeeze the reset spring 17 through the plug-in rod 16. When the magnet block 24 moves upward out of the opening groove 20, the cross plate 19 can no longer be subjected to the pulling force brought by the magnet block 24. The two placement tables 6 will return to their original positions under the rebound action of the reset spring 17. The two placement tables 6 will be reunited, and the plastic bottles 35 can continue to be stacked on the top of the placement table 6 for a new round of processing.

[0046] like Figure 1 and Fig. 9 As shown, the sides of the two stacking plates 4 are fixedly connected with fixing frames 13, and the two fixing frames 13 are fixedly installed on the top of the workbench 1. A discharge port 31 is opened at the center of the top surface of the workbench 1, and the discharge port 31 is located directly below the combined position of the two placement tables 6.

[0047] During operation: when the two placement tables 6 are pulled apart from each other by pulling the assembly apart, the plastic bottles 35 between the two stacking plates 4 will fall down and drop out from the discharge port 31. It is worth noting that the cleaning device can be placed below the discharge port 31, so that the punctured plastic bottles 35 can directly enter the cleaning device for cleaning, and the cleaning agent can better flow from the bottle mouth and the tied mouth of the plastic bottle 35 into the interior of the plastic bottle 35 for comprehensive cleaning, and the position of the two stacking plates 4 is fixed by the fixing frame 13.

[0048] like Figures 7 and 8 As shown, a magnetic isolation plate 28 is fixedly installed on the top of the mounting platform 25, and the magnetic isolation plate 28 is located between the second magnet block 26 and the third magnet block 27.

[0049] During operation: a magnetic isolation plate 28 is installed between the second magnet block 26 and the third magnet block 27, so that the magnetic isolation plate 28 can isolate the magnetic influence between the second magnet block 26 and the third magnet block 27, avoiding affecting the magnetic influence on the first magnet block 24.

[0050] like Figure 1 and Fig. 9 As shown, a support frame 34 is fixedly connected to the top of the workbench 1, a lower material bin 32 is fixedly connected to the inner side of the support frame 34, a feeding bin 33 is fixedly connected to the top of the lower material bin 32, and the bottom opening of the lower material bin 32 is located directly above the stacking area formed by the two stacking plates 4.

[0051] Multiple plastic bottles 35 that need to be recycled are continuously put into the feeding bin 33 horizontally. After passing through the feeding bin 33, the plastic bottles 35 will automatically adjust their positions and enter the stacking area formed by the two stacking plates 4 in a horizontal state. As the number of placed plastic bottles 35 increases, a horizontal stack is formed above the placement table 6, which is convenient for the puncturing component to puncture multiple plastic bottles 35 at the same time.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
