Description

Technical Field

[0001] This application relates to the field of recycling technology for waste containing plastic components, and in particular to a continuous automated paper-plastic separation system. Background Technology

[0002] Currently, paper-plastic bags can be recycled and reused through a series of processes such as paper-plastic separation, washing, and filtration.

[0003] Paper-plastic separation of paper bags is generally achieved using a paper-plastic separator. The separator consists of a machine body with a feed hopper at the top and a discharge port on one side at the bottom. To ensure continuous operation, an inclined conveyor is typically installed on one side of the separator. The conveyor belt on this conveyor continuously feeds waste materials such as paper-plastic bags into the separator for separation.

[0004] However, during the process of using a conveyor to transport waste, the waste will adhere to the surface of the conveyor belt for a period of time and is easily separated from the conveyor belt during the return trip, causing some waste to fall outside the feed hopper of the paper-plastic separator. Summary of the Invention

[0005] To address the issue of waste materials easily falling outside the feed hopper, this application provides a continuous automated paper-plastic separation system.

[0006] This application provides a continuous automated paper-plastic separation system, which adopts the following technical solution:

[0007] A continuous automated paper-plastic separation system includes a paper-plastic separator and a conveyor. The conveyor includes a frame and a conveyor belt. The frame includes two parallel side support plates and a support base for supporting the two side support plates. A drive roller and a driven roller are rotatably connected between the two side support plates. The conveyor belt is tensioned between the drive roller and the driven roller. A plurality of horizontal baffles are evenly spaced on the surface of the conveyor belt, and the horizontal baffles are parallel to the drive roller. A material drop plate is hinged to the side of the horizontal baffle facing the direction of movement of the conveyor belt. A scraper parallel to the horizontal baffle is slidably connected to the upper surface of the material drop plate, and the sliding direction of the scraper is perpendicular to the horizontal baffle. A return mechanism is also provided on the frame. The conveyor belt includes an upper half near the paper-plastic separator and a lower half away from the paper-plastic separator. The return mechanism is used to drive the material drop plate of the lower half of the conveyor belt to rotate and fit against the surface of the conveyor belt.

[0008] By adopting the above technical solution, when the material discharge plate moves with the conveyor belt to the lower part near the paper-plastic separator, the material discharge plate rotates to a vertical position under its own gravity. Then, the scraper on the material discharge plate moves away from the horizontal bar under its own gravity and scrapes off the waste material attached to the material discharge plate, effectively reducing the waste material attached to the material discharge plate. The retraction mechanism can adjust the material discharge plate back to the position of adhering to the conveyor belt in the lower half of the conveyor belt. During the retraction process, the scraper on the material discharge plate located in the conveyor belt conveying section will reset under its own gravity.

[0009] Optionally, the retraction mechanism includes a push block and a positioning block; a positioning groove is provided on the side of the crossbar facing the blanking plate, the positioning block is slidably connected in the positioning groove, and an elastic element is also provided in the positioning groove for driving the positioning block to extend out of the positioning groove. Under the action of the elastic element, the positioning block extends out of the positioning groove and pushes the blanking plate to rotate to a position that fits against the surface of the conveyor belt; an installation groove is provided on the side wall of the positioning groove away from the conveyor belt, the push block is slidably connected in the installation groove, and an adjustment hole for inserting the push block is provided through the positioning block; a guide surface is provided on the end of the push block near the positioning groove for squeezing the positioning block and causing the positioning block to retract into the positioning groove; a guide surface is provided on the side of the two side support plates that are close to each other along the conveyor belt. The conveyor belt has a guide groove surrounding the conveyor track; the horizontal stop bar has a movable groove communicating with the mounting groove on the side near the side support plate; the push block has a guide rod fixed on the side near the side support plate, the guide rod passes through the movable groove and is located in the guide groove; the guide groove includes a first guide part, a second guide part, and a connecting part connecting the first guide part and the second guide part, the first guide part is located in the lower half of the conveyor belt, and the second guide part is located in the upper half of the conveyor belt; when the guide rod is located in the first guide part, the push block separates from the adjustment hole, and the positioning block extends out of the positioning groove; when the guide rod is located in the second guide part, the push block is inserted into the adjustment hole, so that the positioning block is completely retracted into the positioning groove.

[0010] By adopting the above technical solution, when the conveyor belt moves the return section of the blanking plate to the position of the first guide section, the push block is retracted into the mounting groove and separated from the adjustment hole, so that the positioning block extends out of the positioning groove under the action of the elastic element and pushes the blanking plate to keep it in the position of adhering to the surface of the conveyor belt, so as to restrict the blanking plate from flipping in the direction away from the conveyor belt, thus realizing the return operation of the blanking plate.

[0011] Optionally, an elastic ball is movably provided on one side of the two side support plates that are close to each other. The elastic ball is located at the end of the conveyor belt return section near the paper-plastic separator. The elastic ball blocks the movement path of the material drop plate, and the crossbar can slide the elastic ball away with the material drop plate.

[0012] By adopting the above technical solution, the elastic ball can provide a certain resistance to the material drop plate, so that when the material drop plate passes over the elastic ball under the action of its own inertia, it will swing and further drive the waste material attached to the material drop plate to fall.

[0013] Optionally, the material discharge plate has a slot extending perpendicular to the length of the crossbar on the side away from the conveyor belt, and the scraper is fixed with a slider that is slidably connected in the slot.

[0014] Optionally, the frame may further include a protective cover disposed between two side support plates, the protective cover being located at the end of the side support plates away from the paper-plastic separator and enclosing the conveyor belt.

[0015] By adopting the above technical solution, the protective cover can effectively wrap the material drop plate located at the end of the conveyor belt away from the paper-plastic separator, preventing waste from falling onto the material drop plate.

[0016] Optionally, the elastic element includes a first spring, one end of which is connected to the bottom of the positioning groove, and the other end of which is connected to the positioning block.

[0017] Optionally, the side support plate is provided with a groove adapted to the elastic ball, the elastic ball is slidably connected in the groove, and a second spring is provided in the groove to connect with the elastic ball and to push the elastic ball partially into the groove.

[0018] Optionally, a support plate located between the driving roller and the driven roller is fixed between the two side support plates, and the conveyor belt rests on the support plate.

[0019] By adopting the above technical solution and setting a support plate between the two side support plates, the stability of the conveyor belt during transport can be improved.

[0020] In summary, this application includes at least one of the following beneficial effects:

[0021] 1. This application reduces the amount of waste adhering to the conveyor belt by means of a hinged discharge plate and a scraper that slides on the discharge plate;

[0022] 2. The elastic ball setting allows the material drop plate to swing, thereby further reducing the adhesion of waste material on the material drop plate. Attached Figure Description

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a continuous automated paper-plastic separation system.

[0033] Reference Figure 1 The continuous automated paper-plastic separation system includes a paper-plastic separator 1 and a conveyor 2. The conveyor 2 is set at an inclination, with the higher end of the conveyor 2 located at the feed hopper 111 of the paper-plastic separator 1 and the lower end of the conveyor 2 close to the ground. Waste materials that need to be separated from paper-plastic materials can be continuously fed into the paper-plastic separator 1 for processing through the conveyor 2.

[0034] Reference Figure 2 , 3The conveyor 2 includes a frame 3 and a conveyor belt 4. The frame 3 includes two side support plates 5 and a support base 32 supporting the two side support plates 5. A drive roller 6 and a driven roller 7 are rotatably connected between the two side support plates 5. A motor 8 is fixedly mounted on the outer side of one of the side support plates 5, and the output shaft of the motor 8 passes through the side support plate 5 and is fixedly connected to the drive roller 6. The drive roller 6 and the driven roller 7 are parallel to each other and are located at opposite ends of the length of the side support plates 5. The conveyor belt 4 is tensioned between the drive roller 6 and the driven roller 7 for conveying waste material. A support plate 9 is also fixedly connected between the two side support plates 5. The support plate 9 is located between the drive roller 6 and the driven roller 7, and the conveyor belt 4 rests on the support plate 9, which provides support and improves the stability of the conveyor belt 4 during transmission.

[0035] Reference Figure 3 , 4 A number of equally spaced horizontal baffles 10 are fixed on the conveyor belt 4. The horizontal baffles 10 are parallel to the drive roller 6. The horizontal baffles 10 can increase the conveying capacity of the conveyor belt 4, making it less likely for waste to slide down along the inclined direction of the conveyor belt 4 when conveying waste. A material drop plate 11 is hinged to the side of the horizontal baffle 10 facing the transmission direction of the conveyor belt 4. The material drop plate 11 can cover the conveyor belt 4 between adjacent horizontal baffles 10.

[0036] A scraper 12 is slidably connected to the blanking plate 11. The scraper 12 is parallel to the horizontal stop 10 and slides in a direction perpendicular to the horizontal stop 10. Specifically, a groove 14 extending in a direction perpendicular to the horizontal stop 10 is provided on the upper surface of the blanking plate 11. The groove 14 has a dovetail-shaped structure. A slider 13 adapted to the groove 14 is fixed on the scraper 12. The slider 13 is slidably connected in the groove 14.

[0037] When the discharge plate 11 on the conveyor belt 4 reaches above the feed hopper 111 of the paper-plastic separator 1, the discharge plate 11 rotates to a vertical position under its own weight, and the scraper 12 on the discharge plate 11 moves away from the horizontal baffle 10 under its own action, and scrapes off the waste on the discharge plate 11, reducing the amount of waste attached to the discharge plate 11.

[0038] Reference Figure 3 , 4 The frame 3 is also equipped with a return mechanism. The conveyor belt 4 includes an upper half near the paper-plastic separator 1 and a lower half away from the paper-plastic separator 1. The return mechanism is used to drive the material drop plate 11 of the lower half of the conveyor belt 4 to rotate and adhere to the surface of the conveyor belt 4.

[0039] Specifically, refer to Figure 3 , 45. The retraction mechanism includes a push block 15 and a positioning block 16. A positioning groove 17 is provided on the side of the horizontal stop bar 10 facing the discharge plate 11. The positioning block 16 is slidably connected in the positioning groove 17. An elastic element for driving the positioning block 16 out of the positioning groove 17 is also provided in the positioning groove 17. Specifically, the elastic element includes a first spring 18, one end of which is connected to the bottom of the positioning groove 17, and the other end is connected to the positioning block 16. Without external force, the first spring 18 can drive the positioning block 16 to partially extend out of the positioning groove 17, and the positioning block 16 extending out of the positioning groove 17 can push the discharge plate 11 back to a state of contact with the surface of the conveyor belt 4.

[0040] Reference Figure 5 A mounting groove 19 is provided on the side wall of the positioning groove 17 away from the conveyor belt 4. The push block 15 is slidably connected in the mounting groove 19. An adjustment hole 21 for inserting the push block 15 is provided through the positioning block 16. A guide surface 20 is provided at the end of the push block 15 near the positioning groove 17. The push block 15 can be inserted into the adjustment hole 21 with the help of the guide surface 20. By pressing the side wall of the adjustment hole 21, the positioning block 16 is completely retracted into the positioning groove 17, thereby releasing the restriction on the unloading plate 11.

[0041] Reference Figure 3 , 4 A guide groove 22 is provided on the side of the two side support plates 5 that are close to each other, and it surrounds the conveyor belt 4. The guide groove 22 includes a first guide part 23, a second guide part 24, and a connecting part 25 that connects the first guide part 23 and the second guide part 24. The first guide part 23 is located in the lower half of the conveyor belt 4, and the second guide part 24 is located in the upper half of the conveyor belt 4. A movable groove 26 communicating with the mounting groove 19 is provided on the side of the crossbar 10 near the side support plate 5. A guide rod 27 is fixed on the side of the push block 15 near the side support plate 5. The guide rod 27 passes through the movable groove 26 and is always located in the guide groove 22.

[0042] When the guide rod 27 is located in the first guide section 23, the push block 15 is retracted into the mounting groove 19 and separated from the adjustment hole 21, so that the positioning block 16 extends out of the positioning groove 17 under the action of the first spring 18 and pushes the dropping plate 11 to remain in the position of adhering to the surface of the conveyor belt 4, so as to limit the dropping plate 11 from flipping in the direction away from the conveyor belt 4.

[0043] When the guide rod 27 is located in the second guide section 24, the push block 15 is inserted into the adjustment hole 21 and squeezes the positioning block 16, so that the positioning block 16 is fully inserted into the positioning groove 17, thereby releasing the limit of the dropping plate 11, so that when the dropping plate 11 reaches the lower part near the end of the paper-plastic separator 1 along with the conveyor belt 4, it can rotate freely.

[0044] Reference Figure 3On the side of the two side support plates 5 that are close to each other, there is also a movable elastic ball 28. The elastic ball 28 is located in the return section of the conveyor belt 4 and close to one end of the paper-plastic separator 1.

[0045] Specifically, refer to Figure 6 , 7 A chute 30 is provided at the end of the side support plate 5 located on the return section of the conveyor belt 4 and near the paper-plastic separator 1. An elastic ball 28 is fitted into the chute 30 and slidably connected within it. A second spring 29 is also installed in the chute 30, with one end connected to the bottom of the chute 30 and the other end connected to the elastic ball 28. Under the action of the second spring 29, part of the elastic ball 28 extends out of the chute 30 and is blocked on the movement trajectory of the discharge plate 11. A limiting ring 33 is also interference-fitted at the opening of the chute 30 to prevent the elastic ball 28 from detaching from the chute 30.

[0046] As the material drop plate 11 transitions from the conveyor end of the conveyor belt 4 towards the return section, the elastic ball 28 blocks the material drop plate 11, causing it to abut against the crossbar 10. After the crossbar 10, carrying the material drop plate 11, squeezes and passes the elastic ball 28, the material drop plate 11, no longer blocked by the elastic ball 28, rotates vertically under its own weight and swings due to inertia, allowing the material drop plate 11 to further reduce the waste adhering to it through this swinging motion.

[0047] Reference Figure 2 The frame 3 also includes a protective cover 31 fixed between two side support plates 5. The protective cover 31 is located at the end of the side support plate 5 away from the paper-plastic separator 1 and encloses the conveyor belt 4. A space is left between the protective cover 31 and the conveyor belt 4 for the material drop plate 11 to move with the conveyor belt 4.

[0048] The implementation principle of a continuous automated paper-plastic separation system according to an embodiment of this application is as follows:

[0049] When waste material is conveyed to the feed hopper 111 of the paper-plastic separator 1 via the conveyor belt 4, the discharge plate 11 oscillates after being squeezed by the elastic ball 28, and the scraper 12 on the discharge plate 11 moves from the end near the crossbar 10 to the end away from the crossbar 10, so that the waste material attached to the discharge plate 11 can be separated from the discharge plate 11 and fall into the feed hopper 111 below. When the discharge plate 11 on the return section of the conveyor belt 4 reaches the lower half of the conveyor belt 4, the guide rod 27 enters the first guide part 23, so that the positioning block 16 pushes the discharge plate 11 to rotate to fit against the surface of the conveyor belt 4 under the action of the first spring 18. When the discharge plate 11 returns to the conveying section of the conveyor belt 4, the scraper 12 on the discharge plate 11 returns to the position near the crossbar 10 under its own gravity.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
