Description

Technical Field

[0001] This invention belongs to the field of plastic recycling technology, and in particular relates to a plastic recycling crushing device for folder production. Background Technology

[0002] Plastic recycling is a manifestation of environmental protection and resource conservation. By recycling waste plastics, environmental pollution can be reduced, and energy can be saved by reusing plastics. At the same time, recycled plastics can be used to make a variety of plastic products, including folders and plastic containers. Furthermore, plastic products that have been manufactured and worn down over a long period of use can also be recycled again, which can greatly reduce plastic consumption.

[0003] In the process of recycling plastics, the plastics need to be crushed. Because plastic products such as folders are relatively hard and are in sheet form, they are prone to stacking. If they are piled up in large quantities, the crushing rollers need to exert more force to crush them, which will cause greater wear on the crushing rollers and reduce the overall service life of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a plastic recycling crushing device for folder production, which addresses the problem that sheet plastics of the same type, such as folders, tend to stack during crushing, hindering the crushing process by the crushing roller.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plastic recycling crushing device for folder production, comprising a crushing chamber, two crushing rollers inside the crushing chamber, a drive module on the outer wall of the crushing chamber, the drive module having two output ends, each output end being connected to a corresponding crushing roller, support plates installed on both sides of the crushing chamber, and a bracket at the bottom of the crushing chamber, and further comprising:

[0006] The conveying assembly includes a feeding bin disposed at the top of the crushing chamber, and the feeding bin has an opening at a position corresponding to the feed inlet at the top of the crushing chamber;

[0012] A connecting frame is installed on one side of the baffle, and the connecting seat is slidably connected to the internal sliding groove of the connecting frame through a connecting post at one end. The movement of the connecting seat compresses the connecting frame, thereby causing the baffle to rotate.

[0013] As a further description of the above technical solution:

[0014] The conveying assembly further includes: a telescopic belt, one end of which is installed at the opening of the feeding hopper, and the other end of which is folded back and disposed at the bottom of the feeding hopper;

[0017] A movable module is located at the other end of the slide plate. The movable module drives the slide plate to move, thereby changing the position of the telescopic belt and thus changing the area of ​​the telescopic belt that it covers the opening of the feeding hopper.

[0018] As a further description of the above technical solution:

[0019] It also includes: a rotary assembly, which includes a screen ring that penetrates the inside of the crushing chamber, with the top surface of the support plate in contact with the bottom surface of the screen ring, a toothed ring installed on one side of the screen ring, and a partition plate installed inside the screen ring, with multiple partition plates arranged circumferentially.

[0020] A power module is mounted on the top of the support plate, and the output end of the power module meshes with the gear ring.

[0021] A barrier is installed on the inner wall of the crushing chamber, and the toothed ring is located in the gap between the barrier and the inner wall of the crushing chamber.

[0022] As a further description of the above technical solution:

The rotation of the mounting shaft drives the rubber plate to move the broken material on the surface of the screen ring.

[0025] As a further description of the above technical solution:

[0026] The rotary assembly further includes a guide plate, which is rotatably mounted on the inner wall of the crushing chamber via shafts at both ends.

[0027] The first gear is mounted on one end of the mounting shaft. A second gear meshes with one side of the first gear, and the bottom end of the second gear meshes with a gear ring. Both the first gear and the second gear are located inside the enclosure.

[0028] As a further description of the above technical solution:

[0029] The rotary assembly further includes: a first turntable, which is mounted on one end of the mounting shaft, and a first deflector is mounted on one side of the first turntable;

[0030] A connecting rod is installed at one end of a guide plate, and a sliding groove is provided inside the connecting rod. A first deflector is slidably connected to the connecting rod through the sliding groove. The rotation of the first turntable causes the first deflector to drive the connecting rod to swing, thereby causing the guide plate to swing.

[0031] As a further description of the above technical solution:

[0032] It also includes: a toggle assembly, the toggle assembly comprising a rotating shaft rotatably mounted on the inner wall of the crushing chamber, and two rotating shafts are provided, with the two rotating shafts respectively located above the two crushing rollers;

[0033] The teeth are installed on the outer wall of the rotating shaft, and multiple teeth are evenly arranged. The teeth on the outer walls of the two rotating shafts correspond to the gap between the biting discs of the two crushing rollers.

[0034] As a further description of the above technical solution:

[0035] The actuation assembly further includes a lever, which is installed at one end of the rotating shaft and is located outside the crushing chamber.

[0036] A fixing plate is installed on the outer wall of the crushing chamber. A third spring is installed on one side of the fixing plate, and the other end of the third spring is fixedly connected to the lever.

[0037] As a further description of the above technical solution:

[0038] The actuating assembly further includes a second turntable, which is installed at the other end of the crushing roller. A second actuating post is installed on the surface of the second turntable. The second turntable drives the second actuating post to rotate, and the second actuating post can push the bottom end of the lever, thereby driving the rotating shaft to rotate through the lever.

[0039] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0040] 1. In this invention, by incorporating a conveying component, the design allows for the restriction of the number of folders that can pass through during the crushing of folders by changing the angle between the baffle and the inner wall of the feeding hopper. This prevents the folders from becoming too thick and causing blockage during the crushing process, thus ensuring the stable operation of the crushing roller. Furthermore, by changing the position of the sliding plate, the reversing position of the telescopic belt can be altered, thereby changing the falling position of the folders and preventing excessive local accumulation that could affect crushing efficiency. This further ensures the stable operation of the crushing roller.

[0041] 2. In this invention, by incorporating a rotating component, the fragments can be sieved through a screen ring after the folder has been crushed. The rotation of the screen ring and the partition drive unqualified fragments upwards, causing them to fall back into the crushing chamber for further crushing. This ensures the completeness of the folder's crushing and guarantees the quality of the crushed items. Furthermore, the rubber plate can move the fragments on the screen ring surface to prevent fragment accumulation, which would hinder the sieving process. This ensures that the screen ring can quickly sieve the fragments, thereby improving efficiency.

[0042] 3. In this invention, by incorporating a toggle assembly, the second toggle pin can be used to aggle the lever during the crushing process of the folder. This causes the toggle teeth to swing, thereby aggleing the horizontally positioned folder and gradually lifting it up so that it can enter the crushing rollers for crushing. This ensures that the folder inside the crushing chamber can smoothly enter the crushing rollers for crushing, avoiding the situation where the folder cannot be crushed due to its horizontal position.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Please see Figures 1-9 This invention provides a technical solution: a plastic recycling crushing device for folder production, comprising a crushing chamber 2, two crushing rollers 8 inside the crushing chamber 2, a drive module 6 on the outer wall of the crushing chamber 2, and the drive module 6 having two output ends, each output end being connected to a corresponding crushing roller 8; support plates 3 installed on both sides of the crushing chamber 2; and a bracket 1 at the bottom of the crushing chamber 2. The device also includes:

[0056] like Figure 6 , Figure 7 As shown, the conveying assembly 5 includes a feeding bin 504 disposed at the top of the crushing bin 2, and the feeding bin 504 has an opening at a position corresponding to the feed inlet at the top of the crushing bin 2;

[0057] Conveyor belt 505 is embedded in the side wall of feeding bin 504;

[0058] The hinge seat 503 is installed on the inner wall of the other side of the feeding bin 504, and a baffle 501 is rotatably installed on the outer wall of the hinge seat 503.

[0059] The conveying assembly 5 also includes an electric push rod 502, which is installed on the outer wall of the feeding bin 504 and corresponds to the baffle 501. The telescopic end of the electric push rod 502 passes through the feeding bin 504 and is equipped with a fixed seat 510.

[0060] The connecting seat 508 is slidably installed inside the fixed seat 510, and a first spring 509 is installed on one side of the connecting seat 508, and the other end of the first spring 509 is fixedly connected to the fixed seat 510.

[0061] The connecting frame 507 is installed on one side of the baffle 501, and the connecting seat 508 is slidably connected to the internal sliding groove of the connecting frame 507 through the connecting post at one end. The movement of the connecting seat 508 can squeeze the connecting frame 507, thereby driving the baffle 501 to rotate.

[0062] like Figure 8 As shown, the conveying assembly 5 also includes: a telescopic belt 506, one end of which is installed at the opening of the feeding bin 504, and the other end of which is folded back and disposed at the bottom of the feeding bin 504;

[0063] The slider 513 is installed at one end of the telescopic belt 506 and is slidably disposed in the bottom groove of the feeding bin 504. A second spring 512 is installed on one side of the slider 513 and the other end of the second spring 512 is fixedly connected to the feeding bin 504.

[0064] The slide plate 511 is slidably installed in the bottom groove of the feeding bin 504, and one end of the slide plate 511 abuts against the surface of the telescopic belt 506, and the telescopic belt 506 folds back from one end of the slide plate 511.

[0065] The movable module 514 is located at the other end of the slide plate 511. The movable module 514 drives the slide plate 511 to move, thereby changing the folding position of the telescopic belt 506 and thus changing the area of ​​the telescopic belt 506 covering the opening of the feeding bin 504.

[0066] Specifically: When crushing folders, when the folders are placed in the feeding bin 504, the folders can be moved by the friction between the conveyor belt 505 and the folders. At the same time, the connecting seat 508 can be moved by the electric push rod 502. Then, the connection between the connecting seat 508 and the connecting frame 507 pushes the baffle 501 to move. In this way, the baffle 501 blocks the inside of the feeding bin 504 to prevent too many folders from entering the crushing bin 2 through the opening of the feeding bin 504, which would cause the crushing roller 8 to get stuck. In the process of the baffle 501 blocking and limiting the folders, if too many folders are piled up on one side of the baffle 501, the baffle 501 will rotate under the push of the folders and compress the first spring 509, thus ensuring that the folders can pass through smoothly.

[0067] Furthermore, after the folder passes through the baffle 501, it moves to the position where the telescopic belt 506 turns back and falls into the crushing chamber 2 from the opening position corresponding to the top of the feeding bin 504. At the same time, the sliding plate 511 can be moved by the moving module 514 to change the extension length of the sliding plate 511. As the position of one end of the sliding plate 511 changes, the telescopic belt 506 turns back, thereby changing the falling position of the folder and preventing the folder from falling in a single position for a long time.

[0068] like Figure 3 , Figure 4 and Figure 5 As shown, the rotary assembly 4 includes a screen ring 404 that penetrates the inside of the crushing chamber 2, and the top surface of the support plate 3 is in contact with the bottom surface of the screen ring 404. A toothed ring 403 is installed on one side of the screen ring 404, and a partition plate 405 is installed inside the screen ring 404, with multiple partition plates 405 arranged circumferentially.

[0069] The power module 401 is installed on the top of the support plate 3, and the output end of the power module 401 meshes with the gear ring 403.

[0070] Enclosure 402 is installed on the inner wall of crushing chamber 2, and toothed ring 403 is located in the gap between enclosure 402 and inner wall of crushing chamber 2.

[0071] The rotary assembly 4 also includes: a mounting shaft 407, one end of which is rotatably mounted in a through hole inside the enclosure 402;

[0072] Rubber plate 408 is installed on the outer wall of mounting shaft 407. A spring rod 414 is provided in the internal cavity of rubber plate 408, and the other end of spring rod 414 is fixedly connected to mounting shaft 407. The rotation of mounting shaft 407 drives rubber plate 408 to move the broken material on the surface of screen ring 404.

[0073] The rotary assembly 4 also includes a guide plate 406, which is rotatably mounted on the inner wall of the crushing chamber 2 via shafts at both ends. The guide plate 406 and the rubber plate 408 are provided with corresponding openings in an alternating manner. The guide plate 406 guides the flow of crushed material.

[0074] The first gear 409 is installed at one end of the mounting shaft 407. The first gear 409 is meshed with the second gear 410 on one side, and the bottom end of the second gear 410 meshes with the gear ring 403. Both the first gear 409 and the second gear 410 are located inside the enclosure 402.

[0075] The rotary assembly 4 also includes: a first turntable 412, which is installed at one end of the mounting shaft 407, and a first deflector 413 is installed on one side of the first turntable 412;

[0076] The connecting rod 411 is installed at one end of the guide plate 406, and the connecting rod 411 has a sliding groove inside. The first deflector 413 is slidably connected to the connecting rod 411 through the sliding groove. The rotation of the first turntable 412 causes the first deflector 413 to drive the connecting rod 411 to swing, thereby causing the guide plate 406 to swing.

[0077] Specifically: During the crushing process of the crushing roller 8, the toothed ring 403 can be rotated by the power component, which in turn drives the screen ring 404 to rotate. The screen ring 404 can screen the crushed fragments to prevent substandard fragments from falling to the bottom. At the same time, as the screen ring 404 rotates, the partition 405 on the inner wall of the screen ring 404 can move the substandard fragments upward. After moving them to a certain height, the partition 405 rotates to a certain angle, allowing the fragments to fall to the top opening of the crushing chamber 2, where they are crushed again by the crushing roller 8.

[0078] Furthermore, during the rotation of the screen ring 404, the gear ring 403 drives the second gear 410 to rotate, which in turn drives the first gear 409 to rotate, thereby causing the mounting shaft 407 to rotate. During the rotation of the mounting shaft 407, the rubber plate 408 rotates. When the rubber plate 408 contacts the inner side of the screen ring 404, due to its length, the rubber plate 408 can bend to a certain extent, causing the spring rod 414 to bend. As the rubber plate 408 continues to rotate, when the rubber plate 408 separates from the inner wall of the screen ring 404, the spring rod 414 returns to its original position, causing the tail end of the rubber plate 408 to swing rapidly. This swinging motion of the rubber plate 408 pushes the fragments inside the screen ring 404 to move, thus spreading the fragments and facilitating their screening out of the screen ring 404.

[0079] Furthermore, during the rotation of the mounting shaft 407, the first turntable 412 is driven to rotate, thereby driving the first deflector 413 to move. The first deflector 413 pushes the connecting rod 411 to swing, and the swing of the connecting rod 411 drives the guide plate 406 to swing. Under the swing of the guide plate 406, the fragments falling from the crushing wheel are guided, so that the fragments can flow intermittently to both sides of the mounting shaft 407 to avoid excessive accumulation on one side, which would affect the screening effect.

[0080] like Figure 9 As shown, the actuating assembly 7 includes a rotating shaft 702 rotatably mounted on the inner wall of the crushing chamber 2, and there are two rotating shafts 702, with the two rotating shafts 702 respectively located above the two crushing rollers 8.

[0081] The teeth 701 are installed on the outer wall of the rotating shaft 702, and multiple teeth 701 are evenly arranged. The teeth 701 on the outer wall of the two rotating shafts 702 correspond to the gap between the biting discs of the two crushing rollers 8.

[0082] The actuation assembly 7 also includes a lever 703, which is installed at one end of the rotating shaft 702 and is located outside the crushing chamber 2.

[0083] A fixing plate 705 is installed on the outer wall of the crushing chamber 2. A third spring 704 is installed on one side of the fixing plate 705, and the other end of the third spring 704 is fixedly connected to the lever 703.

[0084] The actuating assembly 7 also includes a second turntable 706, which is installed at the other end of the crushing roller 8. A second actuating post 707 is installed on the surface of the second turntable 706. The second turntable 706 drives the second actuating post 707 to rotate, which can push the bottom end of the lever 703, thereby driving the rotating shaft 702 to rotate through the lever 703.

[0085] Specifically: During the rotation of the crushing roller 8, the second turntable 706 is driven to rotate, and the rotation of the second turntable 706 drives the second deflector 707 to rotate. When the second deflector 707 rotates to a certain position, it contacts one side of the deflector 703, causing the deflector 703 to swing as the second deflector 707 moves, thereby driving the rotating shaft 702 to rotate. This causes the deflector teeth 701 to rotate, thereby deflecting the folder in a horizontal state through the deflector teeth 701, causing the folder to gradually stand up, so that the folder can smoothly enter the crushing roller 8 for crushing.

[0086] Furthermore, as the second turntable 706 continues to rotate, when the second shift post 707 moves to a certain position, the second shift post 707 separates from the shift lever 703, thereby pulling the shift lever 703 back to its original position under the action of the third spring 704, and causing the shift tooth 701 to reset again.

[0087] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
