The material shifting assembly includes a material shifting shaft 20 rotatably mounted on the feed trough 10, and a plurality of material shifting rods 21 are fixedly mounted on the material shifting shaft 20; The transmission assembly, the material-discharging shaft 20 is also connected to the pressing plate 7 through the transmission assembly. When the telescopic cylinder 9 drives the pressing plate 7 to rise, the transmission assembly is used to drive the material-discharging shaft 20 to rotate, and sends the corrugated paper to the inner cavity of the upper cylinder 5 through the material-discharging rod 21; when the telescopic cylinder 9 drives the pressing plate 7 to descend, the transmission assembly does not drive the material-discharging shaft 20.

[0024] In the embodiment of the present invention, through the combination arrangement of the pressing component, the material shifting component and the transmission component, when the corrugated paper is added into the feed trough 10, the telescopic cylinder 9 is used to drive the pressing plate 7 to rise, the transmission component can drive the material shifting shaft 20 to rotate, and the corrugated paper is shifted to the inner cavity of the upper cylinder 5 through the material shifting rod 21; the telescopic cylinder 9 is used to drive the pressing plate 7 to descend, and the transmission component does not drive the material shifting shaft 20, so as to avoid the interference between the corrugated paper input and the pressing of the pressing column 6, and the reliability is high, so that the corrugated paper can be reliably added into the inner cavity of the upper cylinder 5, and the corrugated paper is pressed downward by the pressing column 6.

[0025] The central shaft 27 is driven to rotate by the driving assembly, thereby causing the upper crushing assembly and the lower crushing assembly to rotate, thereby achieving the purpose of efficiently crushing the corrugated paper pressed down by the pressing column 6, and storing the crushed corrugated paper in the collecting box 2, which is reliable in application.

[0026] In summary, the waste corrugated paper crushing and recycling device realizes efficient and reliable crushing and recycling of corrugated paper through the coordinated work of pressing, shifting and transmission components, and significantly improves the processing efficiency and stability of equipment operation.

[0027] like Figure 1-Figure 6 As shown, as a preferred embodiment of the present invention, the pressing column 6 adopts a cylindrical structure, and the lower end of the pressing column 6 is chamfered; the pressing column 6 is evenly distributed on the lower side of the pressing plate 7, and the lower end surface of the pressing column 6 is located on the same horizontal plane or the lower end surface contour of the pressing column 6 is consistent with the upper end surface contour of the upper crushing component, so as to improve the pressing reliability of the pressing column 6 on the corrugated paper, that is, the corrugated paper can be tightly attached to the upper crushing component, thereby improving the crushing efficiency.

[0028] The feed chute 10 adopts a U-shaped structure, and the end of the feed chute 10 away from the upper cylinder 5 is tilted upward, which is conducive to the corrugated paper being pushed into and sliding down the inner cavity of the upper cylinder 5; a plurality of rollers 11 are also rotatably installed on the inner bottom of the feed chute 10, and the rollers 11 further improve the smoothness of the feeding rod 21 for pushing the corrugated paper.

[0029] The material-moving rods 21 are evenly distributed on the material-moving shaft 20 in a circumferential direction, and the material-moving rods 21 are made of elastic material, which can meet the needs of moving corrugated paper of different thicknesses and improve the reliability of moving.

[0030] For the structure of the transmission components, refer to Figure 2-Figure 5, specifically as follows: the transmission assembly includes a transmission cross bar 14, a transmission vertical rod 15, a fastening bolt 16, a rack 17, a gear 18, a collar 19, a ratchet gear 22, an arc-shaped elastic telescopic rod 24, a stopper 25 and a hinge support 26, one end of the material-digging shaft 20 is fixed with a collar 19, the outer side of the collar 19 is rotatably mounted with a gear 18, the inner side of the gear 18 is provided with a mounting cavity 23, the collar 19 in the mounting cavity 23 is fixed with a ratchet gear 22, a hinge support 26 is also fixed on the cavity wall of the mounting cavity 23, a stopper 25 that cooperates with the ratchet teeth of the ratchet gear 22 is hinged on the hinge support 26, one side of the stopper 25 is fixed with an arc-shaped elastic telescopic rod 24, and the other end of the arc-shaped elastic telescopic rod 24 is fixedly connected to the cavity wall of the mounting cavity 23; the top of the pressing plate 7 A transmission cross bar 14 is also fixed to the top, and a transmission vertical rod 15 is slidably provided on the transmission cross bar 14. A fastening bolt 16 for locking and fixing the transmission vertical rod 15 is also installed at the end of the transmission cross bar 14. A rack 17 that can be meshed with a gear 18 is also fixed to the transmission vertical rod 15; when the rack 17 moves upward, the stopper 25 abuts against the ratchet teeth of the ratchet gear 22, and the gear 18, the ratchet gear 22, the collar 19, the material-discharging rod 21 and the material-discharging shaft 20 rotate, and the material-discharging rod 21 sends the corrugated paper to the inner cavity of the upper cylinder 5; when the rack 17 moves downward, as the gear 18 rotates, the arc-shaped elastic telescopic rod 24 is compressed, and the stopper 25 slides over the ratchet end of the ratchet gear 22, and the ratchet gear 22, the collar 19, the material-discharging rod 21 and the material-discharging shaft 20 are not driven. In addition, by arranging the transmission vertical rod 15 to be able to perform longitudinal adjustment, the position of the transmission vertical rod 15 can be adjusted so that when the pressing column 6 just moves upward, the rack 17 does not engage with the gear 18, that is, the material removal rod 21 does not rotate at this time, reserving a waiting space to ensure that the space between the pressing column 6 and the upper crushing assembly is sufficient for the input of corrugated paper, which is reliable and flexible.

[0031] It should be noted that, in order to prevent the blocking rod 25 from sliding over the ratchet end of the ratchet gear 22 and causing the ratchet gear 22 to be mis-transmitted, the material-displacing shaft 20 is connected to the feed chute 10 with damping rotation, so that the material-displacing rod 21 will not push the corrugated paper away from the upper cylinder 5. The installation arrangement of the ratchet gear 22, the arc-shaped elastic telescopic rod 24 and the blocking rod 25 can be referred to the method shown in the figure. The arc-shaped elastic telescopic rod 24 plays a role in limiting the blocking rod 25, thereby ensuring that the blocking rod 25 can reliably move the ratchet gear 22. At the same time, the arc-shaped elastic telescopic rod 24 is also used for the blocking rod 25 to slide over the ratchet end of the ratchet gear 22. The arc-shaped elastic telescopic rod 24 adopts an arc-shaped structure, and the center of the arc-shaped elastic telescopic rod 24 is located on the axis of the hinge shaft of the blocking rod 25 and the hinge support 26, so as to ensure reliable operation.

[0032] like Figure 1 , Figure 6 and Figure 7As shown, as a preferred embodiment of the present invention, the inner cavity diameter of the upper cylinder 5 is larger than the inner cavity diameter of the lower cylinder 4, and the lower part of the inner cavity of the upper cylinder 5 is conical, and the lower end of the inner cavity of the upper cylinder 5 is cooperatively connected with the upper end of the inner cavity of the lower cylinder 4; in order to improve the stability of the lower cylinder 4, a reinforcement plate 1 is also fixed to the top of the aggregate box 2, and the reinforcement plate 1 is also fixedly connected to the outer wall of the lower cylinder 4.

[0033] The driving assembly includes a slave pulley 28, a main pulley 30, a transmission belt 31 and a motor 32. A transmission chamber 29 is also opened on the lower side of the storage chamber of the aggregate box 2. A slave pulley 28 is fixed on the central shaft 27 in the transmission chamber 29. A motor 32 is also fixed in the transmission chamber 29. The main pulley 30 is fixed to the output end of the motor 32. The main pulley 30 is connected to the slave pulley 28 through the transmission belt 31. When the motor 32 is started, the central shaft 27 can be driven to rotate under the transmission of the main pulley 30, the transmission belt 31 and the slave pulley 28.

[0034] The upper crushing assembly includes multiple groups of upper crushing parts, and the upper crushing parts include upper crushing rods 36 and crushing columns 37. Multiple upper crushing rods 36 are evenly distributed and fixed on the central axis 27 in the circumferential direction. The upper crushing rods 36 are arranged with the outer ends tilted downward. Multiple cylindrical crushing columns 37 are fixed on both sides of the upper crushing rods 36. The upper crushing rods 36 of two adjacent groups of upper crushing parts are evenly staggered to improve the reliability of crushing. A plurality of conical crushing teeth 38 are also fixed on the upper side of the upper crushing rods 36 of the topmost group of upper crushing parts. The crushing teeth 38 can be used to pre-crush the corrugated paper pressed down by the pressing column 6, so as to facilitate further crushing by the subsequent upper crushing rods 36 and crushing columns 37.

[0035] The lower crushing assembly includes multiple groups of lower crushing parts, each of which includes a lower crushing rod 35. Multiple lower crushing rods 35 are evenly distributed circumferentially and horizontally fixed on the central axis 27. The lower crushing rods 35 of two adjacent groups of lower crushing parts are evenly staggered to improve the reliability of crushing.

[0036] like Figure 6 and Figure 8As shown, as a preferred embodiment of the present invention, the lower end of the lower cylinder 4 is connected to the storage chamber of the aggregate box 2 through a bottom outlet 44, and a plurality of side chambers 40 are circumferentially distributed at the lower end of the lower cylinder 4, a slide plate 41 is slidably provided in the side chamber 40, an adjusting column 42 is fixed on the inner side of the slide plate 41, the end of the adjusting column 42 away from the slide plate 41 slides and extends into the bottom outlet 44, and the end of the adjusting column 42 away from the slide plate 41 is rounded, and a spring 43 for elastically supporting the slide plate 41 is also provided on the side of the slide plate 41 close to the adjusting column 42 in the side chamber 40; a pressurizer 3 is fixed on the outer wall of the aggregate box 2, and the outlet of the pressurizer 3 is connected to the annular tube 45 through the air pipe 34, and the annular tube 45 is sleeved on the outer side of the lower end of the lower cylinder 4, and the annular tube 45 is also connected to the side chamber 40 correspondingly through the branch pipe 39.

[0037] During operation, the air pipe 34 can be pressurized by the pressurizer 3, so that each side cavity 40 is pressurized by utilizing the connecting structure of the annular tube 45 and the branch tube 39, and the whole formed by the slide plate 41 and the adjusting column 42 overcomes the elastic force of the spring 43 to move, that is, the adjusting column 42 is extended into the bottom outlet 44, and the blocking effect of the adjusting column 42 on the corrugated paper is changed by changing the length of the adjusting column 42, thereby changing the crushing effect of the device on the corrugated paper, and the application is flexible and convenient.

[0038] like Figure 6 As shown, as a preferred embodiment of the present invention, the bottom of the storage cavity of the aggregate box 2 is tilted downward at one end, and a discharge port is opened on the side wall of the aggregate box 2 corresponding to the lower end of the bottom of the storage cavity of the aggregate box 2, and a sealing plate 13 is installed on the discharge port.

[0039] Preferably, a dust shielding mesh 33 is also fixedly installed on the upper part of the lower end of the bottom of the storage cavity of the aggregate box 2, and an exhaust fan 12 for negative pressure suction of the upper space of the dust shielding mesh 33 is installed on the side wall of the aggregate box 2. Through the negative pressure suction of the exhaust fan 12, the material can be more reliably discharged into the storage cavity of the aggregate box 2, and at the same time, the diffusion of dust at the feed trough 10 can be avoided, thereby improving the reliability of the work.

[0040] The above embodiment of the present invention provides a waste corrugated paper crushing and recycling device, and its working principle is as follows: First, the waste corrugated paper is fed into the device through the feed chute 10. The design of the feed chute 10 (U-shaped structure, with one end away from the upper cylinder 5 tilted upward) facilitates the smooth entry of the corrugated paper. The telescopic cylinder 9 drives the pressing plate 7 to rise. During this process, the transmission component drives the material-dispensing shaft 20 to rotate, and the material-dispensing rod 21 then pushes the corrugated paper into the inner cavity of the upper cylinder 5. Next, the telescopic cylinder 9 drives the pressing plate 7 to descend. At this time, the transmission component no longer drives the material-dispensing shaft 20 to prevent the corrugated paper from interfering with the pressing column 6, ensuring that the corrugated paper is stably pressed to the predetermined position.

[0041] When the corrugated paper is pressed into place, the driving assembly (including the motor 32, the main pulley 30, the secondary pulley 28 and the transmission belt 31) drives the central shaft 27 to rotate, so that the upper crushing assembly and the lower crushing assembly installed thereon start to operate. The crushing teeth 38 in the upper crushing assembly first pre-crush the corrugated paper, and then the upper crushing rod 36 and the crushing column 37 continue the crushing operation. At the same time, the lower crushing rod 35 in the lower crushing assembly also participates in the crushing process, and the two work together to achieve efficient crushing of the corrugated paper.

[0042] By controlling the pressure of the pressurizer 3 to apply pressure to the air pipe 34, the positions of the slide plate 41 and the adjustment column 42 can be adjusted, thereby changing the degree of opening of the bottom outlet 44. This design allows the operator to adjust the particle size of the crushed corrugated paper according to actual needs, thereby enhancing the flexibility and application range of the equipment.

[0043] The crushed corrugated paper falls into the collection box 2. Since the bottom of the storage cavity of the collection box 2 is designed to be tilted downward at one end, it helps the material flow smoothly to the discharge port. The sealing plate 13 installed at the discharge port can be opened to discharge the material when necessary. In addition, the dust screen 33 and the exhaust fan 12 installed inside the collection box 2 can effectively reduce the spread of dust and improve the cleanliness of the working environment.

[0044] In summary, the waste corrugated paper crushing and recycling device realizes efficient, flexible and environmentally friendly recycling of waste corrugated paper through the feeding and pressing structure design and the crushing mechanism.

[0045] The PLC controller disclosed in the prior art can be used to control each component. The model and circuit connection of each component are not specifically limited and can be flexibly set in actual application.
