Description

Technical Field

[0001] This invention belongs to the field of waste paper film recycling technology, specifically a waste paper film recycling granulation device. Background Technology

[0002] Waste paper film recycling has multiple values ​​and roles in resource recycling and environmental protection: reducing white pollution (plastic film is difficult to degrade in the natural environment, and random disposal will damage soil structure, pollute water sources, and threaten ecological balance in the long term. Recycling can effectively reduce the environmental residue of such pollutants, which is especially important for the protection of farmland ecosystems) and reducing the pressure of waste disposal (by recycling, the amount of plastic film entering landfills or incinerators is reduced, avoiding secondary pollution). When recycling waste paper film, personnel use granulation equipment to process it into granules.

[0003] In existing granulation equipment, during the processing of waste paper film, a certain amount of waste paper film adheres to the surface of the extrusion mechanism when it is compressed into granules. If the waste paper film adhering to the extrusion mechanism is not cleaned in time, it will affect the forming effect of the waste paper film. Cleaning the waste paper film adhering to the extrusion mechanism is cumbersome and time-consuming, thus reducing the efficiency of waste paper film processing.

[0013] Preferably, the granulation box has a discharge chute on its side, and the inner walls of the granulation box, the inlet, and the discharge chute are all inclined structures.

[0014] Preferably, the upper end of the spring is fixedly connected to the bottom of the lifting plate, and both the rotating plate and the lifting plate have chamfered edges on their sides.

[0015] Preferably, in the initial state, there is a gap between the top of the striking plate and the inner top wall of the extrusion roller, and one of the rotating plates has a chamfered side abutting against the chamfered side of the lifting plate.

[0016] Preferably, a pair of support plates are fixedly connected to the inner wall of the granulation box. The support plates are inserted into the inside of the extrusion roller and are rotatably connected to the inside of the extrusion roller.

[0017] Preferably, a pair of limiting grooves are provided on the surface of the vertical rod, and a pair of limiting blocks that are slidably connected to the limiting grooves are fixedly connected to the inner wall of the lifting plate.

[0018] Preferably, the side of the connecting frame is provided with a plug-in groove, a metal plate is movably inserted into the plug-in groove, a spring is fixedly connected between the side of the metal plate and the inner side wall of the plug-in groove, and the side of the scraper is coated with a magnetic coating, which is magnetically connected to the metal plate.

[0019] Preferably, a pair of sliding grooves are provided on the inner bottom wall of the insertion slot, and a pair of sliders that are slidably connected to the bottom of the metal plate are fixedly connected to the sliding grooves.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The waste paper film recycling and granulation device of the present invention, when in use, if a large amount of waste paper film adheres to the extrusion roller, affecting the extrusion processing effect of the waste paper film, it is necessary to start a pair of motors two, so that they rotate in opposite directions, thereby causing the rotating shaft and rotating plate connected to them to rotate in opposite directions, so as to push the lifting plate to move upward. When the lifting plate moves upward, its bottom surface will pull the spring one, causing it to move upward and gradually enter a stretched state. At the same time, the top of the lifting plate will drive the fixed rod and the striking plate to move upward. As the rotating plate moves upward, the rotating plate in contact with the lifting plate will gradually move in contact with the lifting plate. The lifting plate separation mechanism separates the lifting plate from the rotating plate. Under the action of a spring force, the lifting plate moves up and down, causing the striking plate to move up and down and strike the inner wall of the extrusion roller. This causes the extrusion roller to vibrate as a whole. Under the action of vibration, the waste paper film adhering to the extrusion roller will be more easily separated from the extrusion roller, thus removing most of the waste paper film adhering to the extrusion roller. This can significantly reduce the impact of a large amount of waste paper film adhering to the extrusion roller on the waste paper film forming process. Moreover, the operation of removing the waste paper film is simple and time-saving, which can improve the efficiency of waste paper film processing.

[0022] 2. The waste paper film recycling and granulation device of the present invention, after striking the extrusion roller, can activate the electric push rod one, so that its telescopic end pushes all the mechanisms on it to move down together and approach the extrusion roller until the side of the scraper with the conical surface abuts against the surface of the extrusion roller (the initial position of the scraper is shown in the figure, and the motor three can be activated so that its output end drives the rotating shaft and the scraper to rotate to adjust the position of the scraper). Then, the motor one is activated to make a pair of extrusion rollers rotate relative to each other. During the rotation, the scraper is used to scrape off the waste paper film adhering to the surface of the extrusion roller, further reducing the amount of waste paper film adhering to the extrusion roller, thereby further reducing the impact of waste paper film adhering to the surface of the extrusion roller on the formation of waste paper film, facilitating personnel to clean the surface of the extrusion roller, and reducing the amount of waste paper film wasted.

[0023] 3. The waste paper film recycling and granulation device of the present invention uses a scraper to scrape the surface of the extrusion rollers. After that, the electric push rod one is started to move upward and reset. Then, the motor three is started, and its output end drives the rotating shaft and the scraper to rotate upward until the side of the scraper with the conical surface is on the same horizontal plane as the connecting frame. Under the magnetic attraction of the magnetic coating on the metal plate, the metal plate will be attracted, causing the metal plate to move on the scraper and gradually move away from the connecting frame. The scraper will push and scrape the waste paper film debris adhering to the scraper through the lower end of the metal plate to remove the waste paper film debris from the scraper. The removed waste paper film debris will fall on a pair of extrusion rollers. Finally, the extrusion rollers are started to extrude the removed waste paper film debris. Therefore, the waste of waste paper film can be further reduced and the processing can be maximized. Attached Figure Description

Detailed Implementation

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Example 1: As Figures 1 to 5 As shown in the figure, a waste paper film recycling granulation device according to an embodiment of the present invention includes a granulation box 1, and a feed inlet 2 is provided on the top of the granulation box 1;

[0037] A pair of motors 3 are fixedly connected to the side of the granulation box 1. A connecting shaft 4 is fixedly connected to the output end of the motors 3. Four sets of connecting rods 5 are fixedly connected to the surface of the connecting shaft 4.

[0038] The four sets of connecting rods 5 are fixedly connected to the same extrusion roller 6 at the ends away from the connecting shaft 4. A vertical rod 7 is fixedly connected to the inner bottom wall of the extrusion roller 6. A spring 8 and a lifting plate 9 are sleeved on the outer end of the vertical rod 7.

[0039] A pair of motors 10 are fixedly connected to the inner wall of the extrusion roller 6. A rotating shaft 11 is fixedly connected to the output end of the motors 10. Four sets of rotating plates 12 are fixedly connected to the surface of the rotating shaft 11.

[0040] A pair of fixing rods 13 are fixedly connected to the top of the lifting plate 9, and the upper ends of the pair of fixing rods 13 are fixedly connected to the same striking plate 14.

[0041] In the existing technology for processing waste paper film, when the extrusion mechanism is used to extrude it into granules, a certain amount of waste paper film will adhere to the surface of the extrusion mechanism. If the waste paper film adhering to the extrusion mechanism is not cleaned in time, it will affect the forming effect of the waste paper film. Cleaning the waste paper film adhering to the extrusion mechanism is cumbersome and time-consuming, which will reduce the efficiency of processing waste paper film.

[0042] When using this invention, start the motor 3, so that its output end drives the connecting shaft 4, connecting rod 5 and extrusion roller 6 to rotate together in the granulation box 1 (a pair of extrusion rollers 6 rotate relative to each other). Then, put the waste paper film into the granulation box 1, and use a pair of relatively rotating extrusion rollers 6 to extrude the waste paper film to make it into granules.

[0043] When a large amount of waste paper film adheres to the extrusion roller 6, affecting the extrusion processing effect of the waste paper film, a pair of motors 10 need to be started to rotate in opposite directions. This causes the rotating shaft 11 and rotating plate 12 connected to them to rotate in opposite directions, pushing the lifting plate 9 to move upward. When the lifting plate 9 moves upward, its bottom surface will pull the spring 8, causing it to move upward and gradually be in a stretched state. At the same time, the top of the lifting plate 9 will drive the fixed rod 13 and the striking plate 14 to move upward.

[0044] As the rotating plate 12 moves upward, the rotating plate 12, which is in contact with the lifting plate 9, will gradually separate from the lifting plate 9. After the lifting plate 9 separates from the rotating plate 12, under the action of the spring force of the spring-8, the lifting plate 9 will move up and down, which in turn will cause the striking plate 14 to move up and down to strike the inner wall of the extrusion roller 6, thereby causing the extrusion roller 6 to vibrate as a whole. Under the action of vibration, the waste paper film adhering to the extrusion roller 6 will be more easily separated from the extrusion roller 6, thereby removing most of the waste paper film adhering to the extrusion roller 6. This can greatly reduce the impact on the formation of waste paper film caused by a large amount of waste paper film adhering to the extrusion roller 6. Moreover, the operation of removing the waste paper film is simple and time-saving, which can improve the efficiency of processing waste paper film.

[0045] like Figure 4 As shown, a pair of electric push rods 30 are fixedly connected to the inner top wall of the granulation box 1. A connecting frame 15 is fixedly connected to the telescopic end of the electric push rod 30. A rotating shaft groove 16 is opened on the side of the connecting frame 15. A rotating shaft 17 is rotatably inserted into the rotating shaft groove 16. The side end of the rotating shaft 17 is fixedly connected to the output end of the motor 18. A scraper 19 is fixedly connected to the surface of the rotating shaft 17.

[0046] After striking the squeezing roller 6, the electric push rod 30 can be activated, causing its telescopic end to push all the mechanisms on it down together and close to the squeezing roller 6 until the side of the scraper 19 with the conical surface abuts against the surface of the squeezing roller 6 (the initial position of the scraper 19 is shown in the figure, and the motor 18 can be activated, causing its output end to drive the rotating shaft 17 and the scraper 19 to rotate, so as to adjust the position of the scraper 19). Then, the motor 3 is activated, causing the pair of squeezing rollers 6 to rotate relative to each other. During the rotation, the scraper 19 is used to scrape off the waste paper film adhering to the surface of the squeezing roller 6, further reducing the amount of waste paper film adhering to the squeezing roller 6. This further reduces the impact of the waste paper film adhering to the surface of the squeezing roller 6 on the formation of waste paper film, and makes it easier for personnel to clean the surface of the squeezing roller 6, and reduces the amount of waste paper film wasted.

[0047] like Figure 4 As shown, the side of motor 18 is fixedly connected to the side of connecting frame 15. In the initial state, there are gaps between the connecting frame 15 and the inner top wall and inner bottom wall of the shaft groove 16.

[0048] When the motor 3 18 is working, its side is fixedly connected to the connecting frame 15, which improves its stability on the connecting frame 15 and makes it less likely to fall off the connecting frame 15. When the motor 3 18 drives the rotating shaft 17 and the scraper 19 to rotate up and down, the scraper 19 can rotate up and down a certain angle because there is a gap between the connecting frame 15 and the rotating shaft groove 16.

[0049] like Figures 1 to 2 As shown, a discharge chute 29 is provided on the side of the granulation box 1, and the inner walls of the granulation box 1, the inlet 2 and the discharge chute 29 are all inclined structures.

[0050] After being squeezed by a pair of extrusion rollers 6, the granulated waste paper film will fall onto the inner bottom wall of the granulation box 1. Before falling, the container for receiving the waste paper film particles needs to be placed below the discharge trough 29 to collect the waste paper film particles. Since the inner walls of the granulation box 1, the inlet 2 and the discharge trough 29 are all inclined structures, it is convenient for the waste paper film to pass through the inlet 2 and fall between the pair of extrusion rollers 6, and it is convenient for the waste paper film particles to roll out of the granulation box 1 and enter the container for receiving the waste paper film particles.

[0051] like Figure 5 As shown, the upper end of the spring 8 is fixedly connected to the bottom of the lifting plate 9, and both the rotating plate 12 and the lifting plate 9 have chamfers on their sides.

[0052] When the lifting plate 9 moves upward, the upper end of the spring 8 is fixedly connected to the bottom of the lifting plate 9, so the spring 8 can move upward with the lifting plate 9. When the rotating plate 12 abuts against the lifting plate 9 and pushes it upward, since both the rotating plate 12 and the lifting plate 9 have chamfers on their sides, it is easy for the rotating plate 12 to slide under the lifting plate 9 and separate from it.

[0053] like Figure 5 As shown, in the initial state, there is a gap between the top of the striking plate 14 and the inner top wall of the extrusion roller 6, and one of the rotating plates 12 with a chamfered side abuts against the chamfered side of the lifting plate 9.

[0054] When the lifting plate 9 is moved upward, the top of the striking plate 14 and the inner top wall of the extrusion roller 6 are separated, so that the striking plate 14 can be moved up a certain height, which makes it easier for the spring 8 to be stretched.

[0055] like Figure 5 As shown, a pair of support plates 20 are fixedly connected to the inner side wall of the granulation box 1. The support plates 20 are inserted into the inside of the extrusion roller 6 and are rotatably connected to the inside of the extrusion roller 6.

[0056] When the motor 3 is started, the extrusion roller 6 rotates inside the granulation box 1. The support plate 20 can support the extrusion roller 6, thereby improving its stability.

[0057] like Figure 9 As shown, a pair of limiting grooves 21 are provided on the surface of the vertical rod 7, and a pair of limiting blocks 22 that are slidably connected to the inner wall of the lifting plate 9 are fixedly connected.

[0058] When the lifting plate 9 moves up and down on the surface of the vertical rod 7, the limiting block 22 can limit the lifting plate 9 to prevent it from being unable to abut against the rotating plate 12 due to its rotation on the vertical rod 7.

[0059] Example 2: Figures 6 to 7 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the side of the connecting frame 15 is provided with a plug groove 23, a metal plate 24 is movably inserted into the plug groove 23, a spring 25 is fixedly connected between the side of the metal plate 24 and the inner side wall of the plug groove 23, and a magnetic coating 26 is coated on the side of the scraper 19, and the magnetic coating 26 is magnetically connected to the metal plate 24.

[0060] After scraping the surface of the extrusion roller 6 with the scraper 19, start the electric push rod 30 to move it up and reset it. Then start the motor 18 to drive the rotating shaft 17 and the scraper 19 to rotate upward until the side of the scraper 19 with the conical surface is on the same horizontal plane as the connecting frame 15.

[0061] Then, under the magnetic attraction of the magnetic coating 26 to the metal plate 24, the metal plate 24 will be attracted, causing the metal plate 24 to move on the scraper 19 and gradually move away from the connecting frame 15 (at this time, the second spring 25 is stretched. When the scraper 19 is rotated downward to keep a sufficient distance from the metal plate 24, the magnetic attraction of the magnetic coating 26 to the metal plate 24 will be removed. Then, under the action of the elastic force of the second spring 25, the metal plate 24 will be pulled to move towards the connecting frame 15 to reset it). The scraper shavings of waste paper film adhering to the scraper 19 will be pushed and scraped by the lower end of the metal plate 24 to remove the waste paper film shavings from the scraper 19.

[0062] The removed waste paper film fragments will fall onto a pair of squeeze rollers 6. Finally, the squeeze rollers 6 are activated to squeeze the removed waste paper film fragments, thus further reducing the waste of waste paper film and maximizing its processing.

[0063] like Figure 6 As shown, a pair of sliding grooves 27 are provided on the inner bottom wall of the insertion groove 23, and a pair of sliders 28 that are slidably connected to the bottom of the metal plate 24 are fixedly connected to the sliding grooves 27.

[0064] When the metal plate 24 moves out of the insertion slot 23, it will drive the slider 28, causing the slider 28 to move within the groove 27. The slider 28 can limit the metal plate 24, making it difficult for it to completely move out of the insertion slot 23 and separate from the connecting frame 15.

[0065] The terms "front," "back," "left," "right," "top," and "bottom" all refer to the figures in the accompanying drawings. Figure 1Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.

[0066] In the description of this invention, it should be understood that the terms "center", "longitudinal", "lateral", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
