[0046] As Figures 1-3 shown, as a specific technical solution, the crushing mechanism 1 includes a housing 101; the top of the housing 101 is fixedly communicated with the feed hopper 2, the bottom of the housing 101 is fixedly communicated with a discharge hopper 105, two crushing rollers 106 are rotatably installed inside the housing 101, and two symmetrical material guiding seats 107 are arranged above the two crushing rollers 106, and the material guiding seats 107 are fixedly connected to the inner wall of the housing 101. A protection box 102 is fixedly installed on the front of the housing 101. Two first cylindrical gears 104 are rotatably installed inside the protection box 102, and the two first cylindrical gears 104 are meshed and connected. A first motor 103 is fixedly installed on the outer wall of the protection box 102, and the output shaft end of the first motor 103 is connected to one of the first cylindrical gears 104; the two crushing rollers 106 are respectively connected to the two first cylindrical gears 104.

[0047] The feed hopper 2 is used to hold the scraps generated in the paper product processing. The scraps enter the housing 101 through the feed hopper 2, are guided by the material guiding seats 107, and enter between the two crushing rollers 106. The first motor 103 drives one of the first cylindrical gears 104 to rotate. Through the meshing transmission of the two first cylindrical gears 104, the two crushing rollers 106 crush the scraps. The crushed scraps enter the feed port 303 of the conveying mechanism 3 through the discharge hopper 105.

[0048] As Figures 1-3As shown in the figure, as a specific technical solution, the conveying mechanism 3 includes a cylinder 301; a spiral conveyor shaft 302 is rotatably installed in the cylinder 301; a second motor 304 is fixedly installed at one end of the cylinder 301, and the output shaft end of the second motor 304 is fixedly connected to one end of the spiral conveyor shaft 302.

[0049] The broken scraps enter the cylinder 301 through the feed inlet 303. The second motor 304 drives the spiral conveyor shaft 302 to rotate, and the spiral conveyor shaft 302 performs spiral conveying, so that the broken scraps are discharged through the discharge outlet 305 and enter the collection box 8.

[0050] As Figures 1-2 shown in the figure, as a specific technical solution, it further includes a support frame 9; the support frame 9 is fixedly connected to the housing 101 of the crushing mechanism 1 and the cylinder 301 of the conveying mechanism 3 for supporting and fixing.

[0051] As Figures 7-8 shown in the figure, as a specific technical solution, it further includes a bottom cylinder 10; the bottom end of the support circular shell 5 is fixedly sleeved on the outer wall of the bottom cylinder 10. The top end of the support circular shell 5 extends inward to form an inner edge. An annular inner cavity 501 is opened inside the inner edge, and the inner cavity 501 is communicated with the oil outlet end of the lubricating oil injection mechanism 4; a plurality of concave holes are provided at the top and bottom of the inner edge and are distributed in an annular array. A ball 502 is arranged in the concave hole, and a communication hole 503 is arranged between the concave hole and the inner cavity 501. An annular groove 601 is opened on the cylindrical surface of the disc 6, and the inner ring of the inner edge is embedded in the annular groove 601, and the ball 502 contacts the bottom and top groove walls of the annular groove 601.

[0052] Through the above design, the rotational installation of the disc 6 is realized. During rotation, rolling friction is carried out through the balls 502, which plays a role in reducing the frictional resistance of rotation; in addition, a lubricating oil injection mechanism 4 is provided to inject lubricating oil into the inner cavity 501. The oil enters the concave hole through the communication hole 503, so that the oil enters the balls 502, and lubrication is carried out when the balls 502 roll, which can further reduce the frictional resistance.

[0053] As Figure 7 、 Figure 9As shown in FIGS. 10, as a specific technical solution, the rotary drive mechanism 11 includes a fixed frame 1101; the fixed frame 1101 is fixedly installed on the bottom inner wall of the bottom cylinder 10, the fixed frame 1101 is rotatably connected to a rotating shaft 1102, a second cylindrical gear 1108 and a first bevel gear 1109 are fixedly sleeved on the rotating shaft 1102, the first bevel gear 1109 is meshed with a second bevel gear 1110, a middle shaft 1106 is fixedly connected to the middle of the second bevel gear 1110, the middle shaft 1106 is fixedly connected to the middle of the disc 6, the second cylindrical gear 1108 is meshed with a vertical rack 1107, the top end of the rack 1107 is fixedly connected to a cross bar 1103, the cross bar 1103 is fixedly connected to an annular plate 1105, the outer ring of the annular plate 1105 is in fit connection with the inner ring of the bottom cylinder 10, and both bottom sides of the annular plate 1105 are elastically connected to the bottom inner wall of the bottom cylinder 10 through second springs 1104.

[0054] As Figure 7 shown in FIGS. 10, as a specific technical solution, the bottom of the first housing 7 extends out from the bottom of the disc 6, the bottom surface of the second housing 13 is flush with the bottom surface of the disc 6; the heights of the extending parts of the multiple first housings 7 from the bottom of the disc 6 increase in the clockwise direction.

[0055] As Figures 10-11 shown, as a specific technical solution, it further includes a pressing mechanism 12; the number of the pressing mechanisms 12 is multiple, and the multiple pressing mechanisms 12 are respectively installed on the multiple first housings 7, the pressing mechanism 12 includes an iron plate 1201 for supporting the collection box 8; a first cylinder 1204 is fixedly connected to the bottom of the iron plate 1201, the first cylinder 1204 is in clearance fit connection with a guide hole opened at the bottom of the first housing 7, a connecting plate 1202 is fixedly connected to the bottom end of the first cylinder 1204, the connecting plate 1202 is elastically connected to the bottom of the first housing 7 through a third spring 1203, a second cylinder 1205 is fixedly connected to the bottom of the connecting plate 1202, and the bottom end of the second cylinder 1205 is in contact with the top surface of the annular plate 1105.

[0056] It should be noted that the overall height of each pressing mechanism 12 is the same. In order to be applicable to the first housings 7 with different depths, the heights of the first cylinder 1204 and the second cylinder 1205 are adjusted accordingly.

[0057] As Figures 11-12 shown, as a specific technical solution, magnetic attraction strips 701 are fixedly installed on both inner walls of the multiple first housings 7, and the bottom end surfaces of the magnetic attraction strips 701 are magnetically connected to the iron plate 1201, and the bottom surfaces of the magnetic attraction strips 701 on the multiple first housings 7 are located on the same horizontal plane.

[0058] When no scraps are collected in all the collection bins 8, the shortest first insert shell 7 extending from the bottom surface of the disc 6 is located below the discharge port 305. The collection bin 8 on this first insert shell 7 is ready to receive the material. After the scraps are crushed and conveyed, they are discharged into the collection bin 8 from the discharge port 305, continuously increasing the weight of the collection bin 8. When the sum of the gravity of the collection bin 8 and the material therein is greater than the magnetic attraction force of the magnetic attraction strip 701 on the iron plate 1201, the collection bin 8 and the iron plate 1201 move downward together until the iron plate 1201 contacts the inner bottom wall of the first insert shell 7 and is blocked. The iron plate 1201 drives the first cylinder 1204, the second cylinder 1205 and the connecting plate 1202 to move downward together, while stretching the third spring 1203. The second cylinder 1205 presses down on the circular ring plate 1105 of the rotation driving mechanism 11. The circular ring plate 1105 drives the cross bar 1103 and the rack 1107 to move downward together, while compressing the second spring 1104. The rack 1107 moves downward, driving the second cylindrical gear 1108, the first bevel gear 1109 and the rotating shaft 1102 to rotate together. Through the meshing transmission of the first bevel gear 1109 and the second bevel gear 1110, the central shaft 1106 drives the disc 6 to rotate by an angle, so that the next first insert shell 7 and the collection bin 8 thereon move below the discharge port 305, and the material is collected through this collection bin 8. After the gravity is greater than the magnetic attraction force, the above actions are repeated to move the next collection bin 8 below the discharge port 305. Until the longest first insert shell 7 extending from the bottom surface of the disc 6 moves below the discharge port 305, it collects the material, and the gravity is greater than the magnetic attraction force, driving the rotation driving mechanism 11 to move the second insert shell 13 and the collection bin 8 thereon below the discharge port 305, completing the function of receiving the material by all the collection bins.

[0059] Through the above design, after a single collection bin 8 collects a fixed amount of material, driven by gravity, all the collection bins 8 rotate by an angle to automatically replace the collection bin 8 at the position of the discharge port 305. The staff does not need to manually replace the collection bin 8 at the discharge port 305 frequently, and only needs to replace it once after all the collection bins 8 are full, providing convenience for the manual operation in the overall collection process.

[0060] During the process of manually removing all the collection bins 8 at once, the iron plate 1201 loses the gravity of the collection bin 8. Due to the elastic force of the third spring 1203, the iron plate 1201, the connecting plate 1202, the first cylinder 1204, and the second cylinder 1205 move upward together. The iron plate 1201 comes into contact with the bottom surface of the magnetic attraction strip 701 again for magnetic attraction. The circular ring plate 1105 loses the downward pressure of the second cylinder 1205. Due to the elastic force of the second spring 1104, the circular ring plate 1105, the cross bar 1103, and the rack 1107 move upward together to reset. The rack 1107 drives the second cylindrical gear 1108, the rotating shaft 1102, and the first bevel gear 1109 to rotate together. Through the meshing of the first bevel gear 1109 and the second bevel gear 1110, the central shaft 1106 drives the disc 6 to rotate and reset, and the first embedding shell 7 with the shortest length extending from the bottom of the disc 6 moves to below the discharge port 305.

[0061] Among them, the magnetic attraction strip 701 can adopt a permanent magnet.

[0062] Among them, the heights of the parts where the multiple first embedding shells 7 extend from the bottom of the disc 6 increase in the clockwise direction, and the increased value for each increment is fixed. After the collection bin 8 in the multiple first embedding shells 7 is filled with materials, the height at which the iron plate 1201 moves downward gradually increases, so as to meet the requirement that after each collection bin 8 is filled, it can push the circular ring plate 1105 downward by a fixed distance; thereby enabling the disc 6 to rotate by a fixed angle to automatically rotate and replace the collection bin 8.

[0063] As Figures 5-6 shown, as a specific technical solution, an arc surface 803 is provided on the outer side of the collection bin 8, and a slope 802 is provided on the part of the arc surface 803 close to the notch; a side groove 801 is provided on the outer wall of the collection bin 8, and the side groove 801 is connected with the magnetic attraction strip 701 in a clearance fit manner. The side groove 801 is used to avoid the magnetic attraction strip 701.

[0064] As Figure 4 shown, as a specific technical solution, the lubricating and oil injection mechanism 4 includes an oil tank 401 fixedly installed on the support frame 9; a connecting frame 403 is fixedly installed on one side of the oil tank 401, and the connecting frame 403 is connected with the driving part. An oil filling port is provided on one side of the oil tank 401, and a sealing cover 402 is provided on the oil filling port. At the same time, a ventilation hole needs to be provided on the sealing cover 402.

[0065] As Figure 4As shown in the figure, as a specific technical solution, the driving part includes an oil cylinder 404 fixedly connected to the connecting frame 403. A piston 406 is fitted and connected inside the oil cylinder 404. One side of the piston 406 is fixedly installed with a movable rod 405. The movable rod 405 penetrates through a through hole provided at one end of the oil cylinder 404, and a spherical surface is provided at one end of the movable rod 405. The end of the movable rod 405 provided with the spherical surface abuts against the arc surface 803 of the collection box 8. A first spring 407 is arranged inside the oil cylinder 404. The piston 406 is elastically connected to the inner side wall of the oil cylinder 404 through the first spring 407.

[0066] As Figure 4 shown in the figure, as a specific technical solution, the inside of the oil cylinder 404 is divided into a rod chamber and a rodless chamber by the piston 406; a first one-way valve 408 and a second one-way valve 410 are installed on one side of the oil cylinder 404. The first one-way valve 408 and the second one-way valve 410 are respectively connected with an oil inlet pipe 409 and an oil outlet pipe 411. The oil inlet pipe 409 is communicated with the bottom of the fuel tank 401, and the oil outlet pipe 411 is communicated with the inner cavity 501 on the support circular shell 5.

[0067] When the movable rod 405 abuts against the arc surface 803 of the collection box 8, the first spring 407 is in a stretched state, and the rodless chamber is in the minimum volume state; when the disc 6 rotates, the collection box 8 thereon moves together. When the inclined surface 802 moves to the position of the movable rod 405 and continues to move, during the process that the notch moves to the position of the movable rod 405, through the elastic force of the first spring 407, the piston 406 and the movable rod 405 move, increasing the length of the movable rod 405 extending out of the oil cylinder 404. At the same time, the volume of the rodless chamber increases, and the oil in the fuel tank 401 enters the rodless chamber through the oil inlet pipe 409 and the first one-way valve 408. The movable rod 405 is located at the notch, as Figure 6 shown in the figure; when the inclined surface 802 moves to the position of the movable rod 405 and the arc surface 803 moves towards the movable rod 405, the movable rod 405 is pushed into the cylinder 301 through extrusion, driving the piston 406 to extrude the oil in the rodless chamber, reducing the volume of the rodless chamber. At the same time, the first spring 407 is stretched, and the extruded oil enters the inner cavity 501 on the support circular shell 5 through the second one-way valve 410 and the oil outlet pipe 411 to provide oil injection.

[0068] Through the above design, automatic oil injection is realized, ensuring continuous lubrication of the rolling balls 502 and reducing the effect of rolling friction.
