However, this patent still has the following problems in practical use:

[0004] It is inconvenient to crush the collected waste because it needs to be crushed after collection to meet the requirements of recycling. This means that the waste needs to be removed and crushed again after collection, which affects work efficiency and reduces efficiency.

[0005] A waste recycling device for medium-density fiberboard (MDF) processing is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a waste recycling device for medium-density fiberboard (MDF) processing, in order to solve the problem mentioned in the background art that it is currently inconvenient to crush the collected waste. This is because the waste needs to be crushed after collection to meet the requirements of recycling, which leads to the need to remove the waste after collection and crush it again, thus affecting work efficiency and reducing work efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a waste recycling device for medium-density fiberboard processing, comprising a device body and an absorption pipe installed inside the top of the device body;

[0009] Also includes:

[0010] The device body is equipped with a crushing and screening assembly inside. The crushing and screening assembly includes a first motor, which is installed on the front of the device body. A disc is rotatably connected inside the device body, and the disc is fixedly connected to the output end of the first motor. A connecting column is fixedly connected to the back of the disc.

[0011] The connecting column is externally slidably connected to a movable frame, and the device body is internally fixedly connected to a partition, and the partition is internally slidably connected to a sliding plate, and the movable frame is fixedly connected to the sliding plate.

[0012] The device has a second motor mounted on the front of the slide plate and a crushing rod rotatably connected to the back of the slide plate. The crushing rod is fixedly connected to the output end of the second motor. The device body has symmetrically fixed mounting blocks inside, and screens are slidably connected between the mounting blocks.

[0013] Preferably, a wedge is fixedly connected to the reverse side of the movable frame, and an installation groove is provided inside the partition, with a first telescopic rod fixedly connected to the installation groove.

[0014] Preferably, a movable strip is fixedly connected to the bottom of the first telescopic rod, and the movable strip can slide inside the mounting groove. A triangular block is fixedly connected to one side of the top of the movable strip, and the wedge block abuts against the triangular block.

[0015] Preferably, a first spring is fixedly connected inside the mounting groove, and the top of the first spring is fixedly connected to the moving bar. A plurality of knocking blocks are symmetrically fixed to the top of the moving bar, and the plurality of knocking blocks abut against the screen.

[0016] Preferably, the multiple knocking blocks are arranged at equal intervals and of equal size.

[0017] Preferably, the device body is provided with symmetrical limiting components inside. The limiting components include a fixing block, and a second spring is fixedly connected to the top of the fixing block. A fixing plate is fixedly connected to the top of the second spring, and a second telescopic rod is fixedly connected between the fixing plate and the fixing block.

[0018] Preferably, a baffle is fixedly connected to one side of the fixing plate, and a locking block is fixedly connected to the top of the fixing plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this waste recycling device for medium-density fiberboard processing can crush the collected waste, thereby avoiding the need for separate crushing later. Furthermore, during crushing, it can also crush waste from different locations within the device body, resulting in more uniform crushing. The specific details are as follows:

[0020] 1. Simultaneously start the first and second motors. The second motor causes the crushing rod to crush the waste material inside the device body, while the first motor drives the disc to rotate. The disc then drives the connecting column to move in a circular motion. The movement of the connecting column causes the moving frame to move, which in turn causes the sliding plate to move back and forth. The movement of the sliding plate causes the second motor and the crushing rod to move back and forth, thus uniformly crushing the waste material in different locations inside the device body. Then, waste blocks that meet the specifications fall from the screen. Next, as the moving frame moves, it also drives the wedge block to move. The wedge block then squeezes the triangular block, causing the triangular block to... The first spring is lowered and compressed. When the triangular block descends, the moving bar and the knocking block also descend. When the wedge reaches the moving position, it disengages from the triangular block, causing the first spring to rebound. The first spring then drives the moving bar to reset, which in turn causes the knocking block to reset, striking the screen and causing it to vibrate. This helps to accelerate the screening speed of the screen, allowing for the crushing of collected waste materials. The crushing position can be changed to ensure uniform crushing of the waste materials. Simultaneously, the screen is struck, thus improving the screening effect of the screen.

[0021] 2. When it is necessary to disassemble and replace the screen, pull the baffles on both sides at the same time to move the fixing plate downward. Then the fixing plate will compress the second spring and drive the locking block to disengage from the inside of the screen, thereby releasing the screen from its limit and allowing the screen to be disassembled and replaced.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1 - Figure 7 The present invention provides the following technical solution:

[0032] A waste recycling device for medium-density fiberboard (MDF) processing includes a device body 1 and an absorption pipe 2 installed inside the top of the device body 1. One end of the absorption pipe 2 is fixedly connected to an absorption head 3. A suction fan 4 is installed on the top of the device body 1. The suction fan 4 is well-known in the prior art, and its specific working principle and process will not be elaborated here. The absorption end of the suction fan 4 is fixedly connected to the absorption pipe 2. A discharge port 101 is installed at the bottom of the device body 1. A crushing and screening assembly 5 is provided inside the device body 1. The crushing and screening assembly 5 includes a first motor 501, which is installed on the front of the device body 1. The device body 1 rotates internally. A disc 502 is connected, and the disc 502 is fixedly connected to the output end of the first motor 501. A connecting post 503 is fixedly connected to the reverse side of the disc 502. A movable frame 504 is slidably connected to the outside of the connecting post 503. A partition 505 is fixedly connected inside the device body 1, and a sliding plate 506 is slidably connected inside the partition 505. The movable frame 504 is fixedly connected to the sliding plate 506. A second motor 507 is mounted on the front of the sliding plate 506, and a crushing rod 508 is rotatably connected to the reverse side of the sliding plate 506. The crushing rod 508 is fixedly connected to the output end of the second motor 507. Mounting blocks 509 are symmetrically fixed inside the device body 1. Figure 2-5As shown, the first motor 501 and the second motor 507 are started simultaneously. The second motor 507 causes the crushing rod 508 to crush the waste inside the device body 1, while the first motor 501 drives the disc 502 to rotate. The disc 502 then drives the connecting column 503 to move in a circular motion. The movement of the connecting column 503 causes the moving frame 504 to move. Since the running trajectory of the connecting column 503 is circular, the connecting column 503 drives the moving frame 504 to move back and forth. The connecting column 503 then drives the sliding plate 506 to move back and forth. The movement of the sliding plate 506 causes the second motor 507 and the crushing rod 508 to move back and forth, thereby uniformly crushing the waste in different positions inside the device body 1. Then, the waste blocks that meet the specifications fall from the screen 510, and the screen 510 is slidably connected between the mounting blocks 509.

[0033] A wedge block 511 is fixedly connected to the reverse side of the movable frame 504, and an installation groove is provided inside the partition plate 505. A first telescopic rod 512 is fixedly connected to the installation groove. A movable strip 513 is fixedly connected to the bottom of the first telescopic rod 512, and the movable strip 513 can slide inside the installation groove. A triangular block 514 is fixedly connected to one side of the top of the movable strip 513, and the wedge block 511 abuts against the triangular block 514. A first spring 515 is fixedly connected inside the installation groove, and the top of the first spring 515 is fixedly connected to the movable strip 513. Multiple knocking blocks 516 are symmetrically fixed to the top of the movable strip 513. Figure 3 , 6 As shown, the moving frame 504 moves, causing the wedge block 511 to move as well. The wedge block 511 then presses against the triangular block 514, causing the triangular block 514 to descend and compress the first spring 515. As the triangular block 514 descends, the moving bar 513 and the striking block 516 also descend. When the wedge block 511 reaches its moving position, it disengages from the triangular block 514, causing the first spring 515 to rebound. The first spring 515 then causes the moving bar 513 to reset, which in turn causes the striking block 516 to reset, allowing it to strike the screen 510, thereby causing the screen 510 to... The vibration generated by the 0 helps to accelerate the screening speed of the screen 510. Secondly, the triangular block 514 can be an isosceles triangle, so that the reciprocating movement of the wedge block 511 can squeeze the triangular block 514, thereby ensuring that the striking block 516 can operate normally, thus enabling the collected waste to be crushed. Moreover, the crushing position can be changed, so that the waste can be crushed evenly. At the same time, it can also strike the screen 510, thereby improving the screening effect of the screen 510. Furthermore, multiple striking blocks 516 abut against the screen 510, and the multiple striking blocks 516 are arranged in a way that is equidistant and of equal size.

[0034] The device body 1 is symmetrically equipped with limiting components 6 inside. The limiting components 6 include a fixing block 601, a second spring 602 fixedly connected to the top of the fixing block 601, a fixing plate 603 fixedly connected to the top of the second spring 602, and a second telescopic rod 604 fixedly connected between the fixing plate 603 and the fixing block 601. A baffle 605 is fixedly connected to one side of the fixing plate 603, and a locking block 606 is fixedly connected to the top of the fixing plate 603. Figure 7 As shown, when the screen 510 needs to be disassembled and replaced, the baffles 605 on both sides are pulled at the same time, causing the fixing plate 603 to move downward. Then the fixing plate 603 will compress the second spring 602, and at the same time, it will drive the locking block 606 to disengage from the inside of the screen 510, thereby releasing the restriction on the screen 510, so that the screen 510 can be disassembled and replaced. The locking block 606 slides with the bottom of the mounting block 509, and the locking block 606 passes through the bottom of the mounting block 509 and engages with the screen 510.

[0035] Working Principle: Before using this waste recycling device for medium-density fiberboard (MDF) processing, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 7As shown, firstly, the waste material from the fiberboard is drawn into the device body 1 through the suction pipe 2 by the suction fan 4 and is located at the top of the screen 510. When the waste material inside the device body 1 accumulates to a certain level, the first motor 501 and the second motor 507 can be started simultaneously. The second motor 507 will cause the crushing rod 508 to crush the waste material inside the device body 1, while the first motor 501 will drive the disc 502 to rotate. Then, the disc 502 will drive the connecting column 503 to move in a circular motion, and then the connecting column 503... The movement of the moving frame 504 causes the connecting column 503 to move. Since the connecting column 503 travels in a circular path, it drives the moving frame 504 to move back and forth. This, in turn, causes the sliding plate 506 to move back and forth. The movement of the sliding plate 506 then causes the second motor 507 and the crushing rod 508 to move back and forth, thus uniformly crushing waste materials at different locations inside the device body 1. The waste blocks that meet the specified dimensions then fall from the screen 510. Furthermore, while the moving frame 504 is moving, it also... The wedge 511 moves, pressing against the triangular block 514, causing it to descend and compress the first spring 515. As the triangular block 514 descends, the moving bar 513 and the striking block 516 also descend. When the wedge 511 reaches its designated position, it disengages from the triangular block 514, causing the first spring 515 to rebound. The first spring 515 then resets the moving bar 513, which in turn resets the striking block 516, allowing it to strike the screen 510. The striking action causes the screen 510 to vibrate, which helps to accelerate the screening speed of the screen 510. Secondly, the triangular block 514 can be an isosceles triangle, so that the reciprocating movement of the wedge block 511 can squeeze the triangular block 514, thereby ensuring that the striking block 516 can operate normally, thus enabling the collected waste to be crushed. Moreover, the crushing position can be changed to ensure uniform crushing of the waste, while also striking the screen 510, which helps to improve the screening effect of the screen 510.

[0036] When the screen 510 needs to be disassembled and replaced, pull the baffles 605 on both sides at the same time, so that the fixing plate 603 moves downward. Then the fixing plate 603 will compress the second spring 602, and at the same time drive the locking block 606 to disengage from the inside of the screen 510, thereby releasing the limit on the screen 510, and then the screen 510 can be disassembled and replaced.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
