DETAILED DESCRIPTION

[0034] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0035] Example 1: Reference Figure 1 and Figure 2 A plastic film sheet online crusher comprises: a box body 1, a lower roller 2, an upper roller 3, a traction assembly 4 and a crusher 5. The top of the box body 1 is provided with an inlet, the inner wall of the box body 1 is rotatably connected with one end of the lower roller 2, the other end of the lower roller 2 is connected to the output end of the reducer, the reducer is installed on the box body 1, and a traction assembly 4 is provided on the box body 1. The traction assembly 4 is rotatably connected with the upper roller 3, the upper roller 3 is arranged parallel to the lower roller 2, and a crusher 5 is rotatably installed in the box body 1, and the output end of the crusher 5 is arranged toward the outlet at the bottom end of the box body 1.

[0036] The principle of the above scheme is:

[0037] When the material to be crushed is a whole roll of plastic film, the traction assembly 4 is started to expand the distance between the upper roller 3 and the lower roller 2, and the whole roll of plastic film is placed between the upper roller 3 and the lower roller 2 from the entrance, and the traction assembly 4 is started again to reduce the distance between the upper roller 3 and the lower roller 2, and the plastic film roll is squeezed, and the reducer is started to drive the lower roller 2 to rotate, and the whole roll of plastic film is guided into the crusher 5 mechanism, and then the plastic debris is discharged through the outlet;

[0038] When the material to be crushed is a plastic film, the traction assembly 4 is started to reduce the distance between the upper roller 3 and the lower roller 2, the plastic film is placed between the upper roller 3 and the lower roller 2 from the inlet, the reducer is started to drive the lower roller 2 to rotate, the plastic film is guided into the crusher 5 mechanism, and then the plastic debris is discharged through the outlet;

[0039] The beneficial effects of the above scheme are:

[0040] The spacing between the upper roller 3 and the lower roller 2 is controlled by the traction assembly 4. When the whole roll of plastic film needs to be crushed, it can be pulled and squeezed at the same time, so that multiple plastic films are rubbed and initially crushed, which reduces the load of the crusher 5 during operation and improves the working efficiency of the device;

[0041] At the same time, the device can pull and crush a single plastic film by adjusting the distance between the upper roller 3 and the lower roller 2, thereby improving the device's ability to crush plastics in various packaging states.

[0042] Example 2: Reference Figure 2 and Figure 3 A slot is opened on each side of the box body 1, and a cover plate 6 is slidably connected to the slot. The cover plate 6 is arranged outside the box body 1, and the output end of the cylinder 7 is hinged on one side of the cover plate 6, and the other end of the cylinder 7 is hinged to the box body 1. The other side of the cover plate 6 is hinged to the box body 1 through a rotating shaft. The two cover plates 6 are respectively rotatably connected to one end of the upper roller 3. A reducer 8 is installed on the cover plate 6, and the output end of the reducer 8 is connected to one end of the upper roller 3.

[0043] The principle of the above scheme is:

[0044] When the distance between the upper roller 3 and the lower roller 2 needs to be enlarged, the cylinder 7 is started, and the output end of the cylinder 7 drives one side of the cover plate 6 hinged thereto to rotate positively on the box body 1 relative to the other side of the cover plate 6;

[0045] When the distance between the upper roller 3 and the lower roller 2 needs to be reduced, the cylinder 7 is started again, and the output end of the cylinder 7 drives one side of the cover plate 6 hinged thereto to rotate on the box body 1 in the opposite direction relative to the other side of the cover plate 6;

[0046] When it is necessary to pull a whole roll of plastic film or a single sheet of plastic film, the reducer 2 8 is started, and the output end of the reducer 2 8 drives the upper roller 3 to rotate, and the upper roller 3 moves in the opposite direction to the rotation direction of the lower roller 2.

[0047] The beneficial effects of the above scheme are:

[0048] By setting the end of the cylinder 7 to be hinged to one side of the cover plate 6, and the other end of the cylinder 7 to be hinged to the box body 1, it is avoided that the cylinder 7 is stuck when working;

[0049] A reducer 2 8 is arranged on the cover plate 6, and the output end of the reducer 2 8 drives the upper roller 3 to move in the opposite direction of the rotation direction of the lower roller 2, which can improve the traction efficiency of the device for a whole roll of plastic film or a single plastic film and prevent it from slipping in the device. At the same time, it is convenient to make the whole roll of plastic film be subjected to uniform pressure when it is squeezed.

[0050] Example 3: Reference Figure 1, Figure 4 and Figure 5 The crusher 5 includes: a knife roller 9, a movable knife 10, a fixed knife 11 and a driving mechanism 12. The knife roller 9 is rotatably connected in the box body 1, and a plurality of movable knives 10 are installed on the knife roller 9. The knife roller 9 is arranged below the lower roller 2. A plurality of fixed knives 11 are installed on the crossbeam in the box body 1. The output end of the movable knife 10 is arranged toward the outlet, and the bottom end of the fixed knife 11 is arranged toward the knife roller 9. The box body 1 is equipped with a driving mechanism 12, and the output end of the driving mechanism 12 is connected to one end of the knife roller 9.

[0051] The principle of the above scheme is:

[0052] A whole roll of plastic film or a single piece of plastic film becomes the material to be crushed after being pulled. After the crushed material continues to move to the output end of the movable knife 10, the driving mechanism 12 is started to drive the knife roller 9 to rotate, and the knife roller 9 drives multiple movable knives 10 to rotate. The material to be crushed is completely crushed after the relative rotation of the movable knife 10 and the fixed knife 11.

[0053] The beneficial effects of the above scheme are:

[0054] A driving mechanism 12 is provided to provide power for the rotation of the cutter roller 9 and the movable cutter 10, and the movable cutter 10 and the fixed cutter 11 move relative to each other, thereby improving the crushing effect of the material to be crushed.

[0055] Example 4: Reference Figure 4 and Figure 7 The driving mechanism 12 includes: a belt cover 13, a pulley 14, a second pulley 15 and a belt 16. The side wall of the box body 1 is provided with a belt cover 13, a reducer 3 is provided on the box body 1, and a pulley 14 is provided at the output end of the reducer 3. The end of the knife roller 9 that passes through the outside of the box body 1 is provided with a second pulley 15. The second pulley 15 is connected to the pulley 14 through a belt 16, and the pulley 14 is arranged in the belt cover 13.

[0056] The principle of the above scheme is:

[0057] When the material to be crushed needs to be crushed, the reducer 3 is started to drive the pulley 14 to rotate, and the pulley 14 drives the pulley 2 15 and the knife roller 9 to rotate synchronously through the belt 16.

[0058] The beneficial effects of the above scheme are:

[0059] A belt 16 is provided to drive the pulley 15 and the knife roller 9 to rotate synchronously, thereby improving the accuracy of the device during rotation;

[0060] A belt cover 13 is installed on the side wall of the box body 1, and the pulley 14, the second pulley 15 and the belt 16 are arranged in the belt cover 13 to prevent dirt from contaminating the belt 16 and to avoid the belt 16 from slipping on the pulley 14 and the second pulley 15, thereby further improving the stability of the device during operation.

[0061] Example 5: Reference Figure 1 A discharge plate 17 is installed in the outlet, the input end of the discharge plate 17 is arranged below the knife roller 9, the output end of the discharge plate 17 is arranged outside the box body 1, and the output end of the discharge plate 17 is arranged below the input end of the discharge plate 17.

[0062] The principle of the above scheme is:

[0063] The crushed plastics fall onto the discharge plate 17 and are uniformly collected under the guidance of the discharge plate 17 .

[0064] The beneficial effects of the above scheme are:

[0065] The difficulty of the device for collecting broken plastics is reduced.

[0066] Example 6: Reference Figure 4 and Figure 6 The box body 1 is provided with a rotating shaft 2, and the side wall of the rotating shaft 2 is provided with the bottom end of a screen 18, the screen 18 is arranged below the moving knife 10, and the top end of the screen 18 is plugged into the bracket locking device on the inner wall of the box body 1.

[0067] The principle of the above scheme is:

[0068] The screen 18 is arranged below the moving knife 10 . After the plastic is crushed, some of the crushed pieces not collected by the discharge plate 17 fall onto the screen 18 .

[0069] The beneficial effects of the above scheme are:

[0070] The screen 18 is provided to collect some plastic fragments to prevent them from falling directly into the box body 1, thereby improving the cleanliness inside the device and reducing the difficulty of cleaning the device.

[0071] Example 7: Reference Figure 4 and Figure 6 The bracket locking device includes: a handwheel 19 and a screw 20. A screw tube is opened on the box body 1, and the screw tube is arranged opposite to the outlet. The screw tube is threadedly connected to the screw 20. One end of the screw 20 is connected to the handwheel 19. The handwheel 19 is arranged outside the box body 1, and the other end of the screw 20 is plugged into and matched with the top of the screen 18.

[0072] The screw tube is provided with a screw hole, and a locking screw 21 is threadedly connected to the screw hole, and the bottom end of the locking screw 21 is in contact with the side wall of the screw 20 .

[0073] The principle of the above scheme is:

[0074] When the screen 18 needs to be removed, the locking screw 21 is turned counterclockwise to disengage the bottom end from the screw 20, and the hand wheel 19 is turned counterclockwise, so that the hand wheel 19 drives the screw 20 to rotate, so that the top end of the screen 18 ends the plug-in fit;

[0075] When the screen 18 needs to be installed, move the top of the screen 18 upwards, turn the hand wheel 19 clockwise, the hand wheel 19 drives the screw 20 to rotate, so that the end of the screw 20 is plugged into the top of the screen 18, turn the locking screw 21 clockwise, so that its bottom end contacts the screw 20, and the screw 20 is locked.

[0076] The beneficial effects of the above scheme are:

[0077] The end of the screw rod 20 is inserted and matched with the top of the screen 18, which reduces the difficulty of installing the screen 18 in the device;

[0078] By setting the bottom end of the locking screw 21 to contact the side wall of the screw 20, the screw 20 is prevented from loosening in the spiral tube due to vibration when the device is working, and the screen 18 is further prevented from falling off when the device is working, thereby improving the stability of the installation of the screen 18.

[0079] Example 8: Reference Figure 4 The box body 1 is provided with a box body front door 22, and the box body front door 22 is arranged below the spiral tube.

[0080] The principle of the above scheme is:

[0081] When the screen 18 needs to be cleaned, first open the front door 22 of the box, end the plug-in cooperation between the screw 20 and the screen 18, and put down the screen 18 to collect some plastic fragments; after the collection is completed, re-fix the screen 18 and close the front door 22 of the box.

[0082] The beneficial effects of the above scheme are:

[0083] By providing the box front door 22, the box 1 can be opened quickly to clean the screen 18, and the screen 18 can be installed and removed easily.

[0084] Example 9: Reference Figure 8 , Fig. 9 and Fig.10The belt cover 13 is provided with a gas tank 23, the gas tank 23 is arranged toward the pulley 14, one end of a heat dissipation pipe 24 is connected to the top of the gas tank 23, the heat dissipation pipe 24 and the gas tank 23 contain carbon dioxide gas, the heat dissipation pipe 24 is fixed outside the belt cover 13, the other end of the heat dissipation pipe 24 equipped with a one-way valve is connected to the bottom end of the gas tank 23, a pipe body 25 is provided on the heat dissipation pipe 24, a pipe body 26 is rotatably connected in the pipe body 25, a plurality of round holes are opened on the pipe body 26, one end of the pipe body 26 is connected to the output end of the motor 27, the motor 27 is installed in the belt cover 13, and the other end of the pipe body 26 is connected to the output end of the motor 27. The side wall of the end of the shaft body 28 is slidably connected inside, and the end of the shaft body 28 is connected to the output end of the motor 27 through a reset spring 29. The other end of the shaft body 28 is equipped with a cylindrical tooth 30. A torsion shaft 34 is rotatably connected inside the belt cover 13. The torsion shaft 34 is connected to the side wall of the connecting plate 31. The side wall of the connecting plate 31 is connected to the belt cover 13 through a torsion spring 35. The torsion spring 35 is coaxially arranged with the torsion shaft 34. An arc-shaped rack 32 is provided at the bottom of the connecting plate 31. The arc-shaped rack 32 is meshed with the cylindrical tooth 30. The other end of the connecting plate 31 is rotatably connected to a tensioning wheel 33, and the tensioning wheel 33 is frictionally matched with the belt 16.

[0085] The principle of the above scheme is:

[0086] Since the belt 16 and the pulley 14 and the second pulley 15 are in frictional cooperation, after the belt 16 rotates for a certain period of time, the pulley 14, the second pulley 15 and the belt 16 generate a large amount of heat. When the belt 16 is heated, it expands, causing the belt 16 to slip on the pulley 14 and the second pulley 15. In the process of dissipating the heat, the pulley 14 transfers the heat to the gas storage tank 23. The carbon dioxide gas in the gas storage tank 23 flows to the outside of the belt cover 13 through the heat dissipation pipe 24 for heat dissipation. At the same time, the motor 27 starts and drives the second tube body 26 to rotate forward. The carbon dioxide gas after heat dissipation flows into the tube body 25. The carbon dioxide gas passes through the circular hole of the second tube body 26 and enters the interior of the second tube body 26. After the shaft body 28 is subjected to the pressure of the flow of carbon dioxide gas, it drives the cylindrical tooth 30 to move along the second tube body 26 toward the arc-shaped rack 32 and mesh with it. At the same time, the reset spring 29 is stretched, and the arc-shaped rack 32 meshing with the cylindrical tooth 30 moves downward, and the arc-shaped rack 32 drives the connecting plate 31 to move downward. The connecting plate 31 drives the torsion shaft 34 to rotate forward, and the torsion spring 35 is twisted. At the same time, the tensioning wheel 33 applies pressure to the top of the belt 16, and the tensioning wheel 33 and the belt 16 are frictionally matched to prevent the belt 16 from being worn;

[0087] When the device finishes working, the temperatures of the pulley 14 and the belt 16 decrease synchronously, the circulation of the carbon dioxide gas in the gas tank 23 ends, the carbon dioxide gas entering the hole tube body 26 through the circle decreases, the reset spring 29 drives the shaft 28 and the cylindrical teeth 30 to reset, the meshing connection between the cylindrical teeth 30 and the arc-shaped rack 32 ends, the motor 27 stops rotating, and under the action of the elastic force of the belt 16 and the reset elastic force of the torsion spring 35, the torsion shaft 34 and the connecting plate 31 are driven to reset, and the tensioning of the belt 16 by the tensioning wheel 33 ends.

[0088] The beneficial effects of the above scheme are:

[0089] By filling the gas storage tank 23 and the heat dissipation pipe 24 with carbon dioxide gas, when the device is working, the gas storage tank 23 can be used to absorb the heat emitted by the pulley 14, so that the carbon dioxide gas expands, and the expanded carbon dioxide gas enters the tube body 26 through the circular hole. The expanded carbon dioxide gas causes the shaft body 28 to drive the cylindrical teeth 30 to move toward the arc-shaped rack 32 and mesh with it, thereby reducing the setting of the power mechanism and making full use of the expansion of the carbon dioxide gas to drive the shaft body 28 to move, so that the cylindrical teeth 30 can quickly mesh with the arc-shaped rack 32 after the pulley 14 is heated.

[0090] A one-way valve is installed in the heat dissipation pipe 24 to prevent the carbon dioxide gas from entering the outside of the belt cover 13 through the heat dissipation pipe 24 from the bottom end of the gas storage tank 23 again;

[0091] The cylindrical teeth 30 are meshed with the arc-shaped rack 32. When the cylindrical teeth 30 rotate, the arc-shaped rack 32 and the connecting plate 31 are driven to move downward, saving space between parts in the device, while improving the efficiency of the movement of the connecting plate 31, and enabling the tensioning wheel 33 to tension the belt 16 in time to prevent the belt 16 from loosening after being heated.

[0092] Example 10: Reference Fig. 9 and Fig.11 The air storage tank 23 is equipped with a pressure relief valve, and the output end of the pressure relief valve is arranged toward the pulley 14. A ventilation filter 36 is opened on the belt cover 13. A plurality of paddles 37 are installed on the pulley 16. The paddles 37 are arranged toward the ventilation filter 36. The paddles 37 are close to the top of the knife roller 9 and higher than the top away from the knife roller 9.

[0093] The principle of the above scheme is:

[0094] When the belt 16 is overheated, the carbon dioxide gas in the gas tank 23 expands rapidly and is then discharged to the pulley 14 through the pressure relief valve, and is guided by the paddle 37 and discharged outside the belt cover 13 after passing through the ventilation filter 36.

[0095] The beneficial effects of the above scheme are:

[0096] When the friction between the belt 16 and the pulley 14 or the second pulley 15 intensifies, the belt 16 overheats, and the carbon dioxide gas discharged from the pressure relief valve is discharged onto the pulley 14, and is discharged out of the belt cover 13 through the guidance of the paddle 37. In the process of the carbon dioxide gas being discharged out of the belt cover 13, the carbon oxide gas can quickly take away the heat on the belt 16, thereby preventing the rubber from melting due to overheating of the belt 16 and protecting the belt 16.

The width of the limiting groove is greater than the width of the lifting groove. A stopper 45 is slidably connected in the limiting groove. The top of the stopper 45 is connected to the bottom end of the lifting plate 44 and contacts and cooperates with the top wall of the limiting groove. The top of the return spring three 47 is installed at the bottom end of the stopper 45, and the bottom end of the return spring three 47 is connected to the bottom wall of the limiting groove. A lubrication shaft 46 is rotatably connected to the lifting plate 44, one side of the lubrication shaft 46 is frictionally matched with the transfer shaft 43, and the other side of the lubrication shaft 46 is frictionally matched with the bottom surface of the belt 16, and the lubrication shaft 46 and the tensioning wheel 33 are staggered.

[0098] The principle of the above scheme is:

[0099] When the tensioning wheel 33 presses the top surface of the belt 16 downward to tension it, the lubricating shaft 46 contacts the belt 16. Under the continuous pressure of the belt 16, the lubricating shaft 46 drives the lifting plate 44 and the stopper 45 to move downward to compress the return spring 47. The transfer shaft 43 rotates with the arc groove on the top surface of the moving plate 45. After the return spring 47 at the bottom end of the stopper 45 is compressed to the limit, the stopper 45 and the return spring 47 drive the moving plate 41 to move downward, and the synchronous guide column 39 moves downward and compresses the return spring 40. The lubricating oil flows to the transfer shaft 43 through the oil drain hole 42, and the transfer shaft 43 evenly applies the lubricating oil to the bottom surface of the belt 16 through the friction of the lubricating shaft 46; after the device finishes tensioning the belt 16, the reset spring 2 40 provides elastic force for the reset of the guide column 39 and the movable plate 41, and the reset spring 3 47 provides elastic force for the reset of the stopper 45, the lifting plate 44, the transfer shaft 43 and the lubricating shaft 46, so as to prepare for the next lubrication.

[0100] The beneficial effects of the above scheme are:

[0101] When the belt 16 is overheated, the lubricating oil on the bottom surface of the belt 16 in contact with the pulley 14 and the pulley 15 is quickly heated and consumed, and the oil drain hole 42 is provided to discharge the lubricating oil, and the transfer shaft 43 performs preliminary application of the lubricating oil. After the mutual rotational friction between the transfer shaft and the lubricating shaft 46, the lubricating oil is finally evenly applied to the belt 16, thereby reducing the tediousness of lubricating the belt 16, and the belt 16 can be automatically maintained at the same time;

[0102] The bottom end of the oil drain hole 42 is provided with a chamfer, and when the movable plate 41 squeezes the oil storage tank downward, the oil drain hole 42 is convenient for fully extracting the lubricating oil. When the oil drain hole 42 finishes applying the lubricating oil to the rotating shaft 43, the remaining lubricating oil is stored in the arc groove and is re-extracted into the oil storage tank under the action of the resetting of the movable plate 41. The chamfer increases the efficiency of the oil storage tank in extracting the lubricating oil.

[0103] Example 12: Reference Figure 1-Figure 14 A control system for an online crusher of plastic film sheets, applied to an online crusher of plastic film sheets described in any of the above items, comprises: a controller and a compressor, the box body 1 is provided with a controller, one end of which is connected to a power supply through a cable, the other end of the controller is provided with ends of a wire, a wire two, a wire three and a wire four, the other end of the wire is connected to a reducer, the other end of wire two is connected to reducer two 8, the other end of wire three is connected to reducer three, wire four is connected to a compressor, and the compressor is connected to a cylinder 7 through a hose.

[0104] The principle of the above scheme is:

[0105] When a whole roll of plastic film or plastic film needs to be crushed, the controller starts the compressor through wire four, and the compressor supplies air to the cylinder 7 through the hose. The output end of the cylinder 7 extends to expand the distance between the upper roller 3 and the lower roller 2. When the whole roll of plastic film is placed between the upper roller 3 and the lower roller 2, the controller controls the compressor to exhaust through the fourth wire, and the output end of the cylinder 7 contracts to reduce the distance between the upper roller 3 and the lower roller 2, and squeeze the whole roll of plastic film. The controller controls the reducer and reducer 2 8 to rotate through wire and wire two respectively, so that the upper roller 3 and the lower roller 2 rotate synchronously in the opposite direction to pull the whole roll of plastic film. The controller controls the reducer three to rotate through wire three, and the reducer three drives the knife roller 9 and the movable knife 10 to rotate, and the movable knife 10 cooperates with the fixed knife 11 to crush the whole roll of plastic film after traction.

[0106] The beneficial effects of the above scheme are:

[0107] By setting one end of the controller to be connected to the power supply through a cable, and the other end of the controller to be connected to the ends of the wire, the wire two, the wire three and the wire four, the system can achieve unified control of the crushing device, reduce the complexity of the system, and facilitate maintenance and repair of the system;

[0108] The other ends of the wire, wire one, wire two, wire three and wire four are connected to the reducer, reducer two 8, reducer three and the compressor respectively, which further reduces the complexity within the system and improves the coordination of the system control components when working synchronously.
