Description

Technical Field

[0001] The invention relates to the technical field of crushing equipment, in particular to a crushing and processing device for scraps used in the production of corrugated paper boxes. Background Art

[0002] In the process of corrugated box production, a large amount of scraps and waste will be generated. In order to improve material utilization, reduce waste and facilitate waste recycling, it is usually necessary to use special crushing equipment to process these scraps.

[0003] The commonly used equipment for corrugated paper scraps and waste is a double-shaft shredder. The double-shaft shredder has two shafts rotating in opposite directions, with blades installed on the shafts. The corrugated paper is shredded by the shearing and tearing action of the blades.

[0004] A double-shaft pulverizer disclosed in Chinese patent publication number CN112055619B pulverizes waste by means of pulverizing blades, and can pulverize waste to a specified particle size more quickly.

[0005] However, compared with the existing technologies in the related fields, firstly, traditional shredders usually rely on a rotating cutter wheel to shred paper. This design has limitations in shredding capacity, especially when dealing with thicker or wetter papers. The rotation speed and torque of the cutter wheel may not be sufficient to effectively shred the papers, resulting in blockage and paper jams; secondly, due to the blade layout and shredding mechanism of the double-shaft shredder, the paper may not be evenly distributed during the shredding process, resulting in uneven shredding, affecting the subsequent recycling and reuse process; thirdly, when dealing with large amounts or large-sized papers, the double-shaft shredder is prone to blockage and paper jams, which not only reduces work efficiency but may also damage the machine; fourthly, due to the uneven contact between the paper and the blade during the shredding process, the blade is severely worn locally, shortening the service life of the blade and increasing maintenance costs. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background technology, and provide a scrap crushing and processing equipment for corrugated paper box production.

[0007] The objective of the present invention is achieved through the following technical scheme: A scrap material crushing and processing equipment for corrugated cardboard box production comprises a crushing box body, two rotating cylinders are symmetrically rotated inside the crushing box body, the outer surfaces of the two rotating cylinders are each provided with a plurality of crushing blades, the outer surfaces of the plurality of crushing blades are each axially slidingly provided with a plurality of crushing teeth, the crushing box body is located inside the two rotating cylinders and is fixedly provided with a guide assembly, the plurality of crushing blades are each connected with the guide assembly through an adjustment assembly, when the rotating cylinder drives the plurality of crushing blades to rotate, the adjustment assembly is coordinated with the guide assembly so that the crushing blade teeth slide axially back and forth on the surface of the crushing blade, the outer surface of the crushing box body corresponding to the positions of the two rotating cylinders is provided with a driving mechanism, the two driving mechanisms are used to control the two rotating cylinders to rotate in opposite directions, and a feed hopper is fixedly installed on the top of the crushing box body.

[0008] Furthermore, the guide assembly includes a fixed shaft, and the outer surface of the fixed shaft is provided with wave grooves at positions corresponding to the plurality of crushing blade discs.

[0009] Furthermore, the wave groove is formed into a circle by a plurality of arc-shaped protrusions staggered around the fixed axis.

[0010] Furthermore, the adjustment assembly includes a screw threadedly connected to the crushing cutter teeth, one end of the screw close to the fixed shaft is threadedly connected to a guide rod, and one end of the guide rod away from the screw is slidably arranged inside the wave groove.

[0011] Furthermore, a ball is provided at one end of the guide rod away from the screw.

[0012] Furthermore, brackets are fixedly provided at both ends of the pulverizing box body at the fixed shaft, and the fixed shaft is fixedly installed between the two brackets.

[0013] Furthermore, the rotating cylinder and the crushing blade disc are both polygonal, the number of corners of the crushing blade disc is greater than the number of corners of the rotating cylinder, a polygonal docking groove with the same number as the corners of the rotating cylinder is opened at the center of the crushing blade disc, and a rotating hole adapted to the fixed shaft is opened at the center of the rotating cylinder.

[0014] Furthermore, a T-shaped slider is fixedly provided at one end of the crushing teeth close to the crushing disc, and a T-shaped sliding groove matching with the T-shaped slider is provided at the position of the crushing disc corresponding to the T-shaped slider.

[0017] The beneficial effects of the present invention are as follows: by providing a shredding disc, shredding teeth, a guide assembly and an adjustment assembly, and utilizing the cooperation between the guide assembly and the adjustment assembly, when the shredding disc rotates, the shredding teeth will perform axial reciprocating sliding on the surface of the shredding disc. The axial reciprocating sliding of the shredding teeth, firstly, can increase the chance of contact with the paper, making the shredding action more frequent and effective, while also having the effects of shredding and cross-cutting, thereby improving the shredding capacity of the equipment; secondly, it helps to distribute the paper more evenly around the shredding disc during the shredding process, thereby avoiding uneven shredding caused by paper position offset or different thicknesses; thirdly, the reciprocating axial sliding of the shredding teeth helps to push the paper into the shredder, thereby reducing blockage or paper jam caused by paper accumulation; fourthly, since the paper contacts the shredding teeth more evenly during the shredding process, it helps to reduce single-point wear of the blade, thereby extending the service life of the blade; fifthly, the irregular distribution of the shredding teeth can cause paper fluctuations, thereby improving the feeding speed and shredding effect.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Additional aspects and advantages of the present invention will be further given in the following description in conjunction with the accompanying drawings, and in part will become apparent from the following description, or may be learned through practice of the present invention.

[0023] An embodiment of a device for crushing and processing scraps for corrugated paper box production according to the present invention is as follows: Figures 1 to 8 As shown, it includes a crushing box 1, and two rotating cylinders 2 are symmetrically rotated inside the crushing box 1. The outer surfaces of the two rotating cylinders 2 are both covered with a plurality of crushing blade discs 3, and the outer surfaces of the plurality of crushing blade discs 3 are axially slidably provided with a plurality of crushing teeth 4, and the crushing teeth 4 are fixedly provided with a T-shaped slider 401 at one end close to the crushing blade disc 3, and the positions of the crushing blade discs 3 corresponding to the T-shaped slider 401 are provided with T-shaped slide grooves 301 adapted thereto, and the crushing box 1 is located inside the two rotating cylinders 2 and is fixedly provided with a guide assembly 5, and the plurality of crushing teeth 4 are connected with the guide assembly 5 through an adjustment assembly 6. When the rotating cylinder 2 drives the plurality of crushing blade discs 3 to rotate, the adjustment assembly 6 is used to cooperate with the guide assembly 5 so that the crushing teeth 4 can slide axially back and forth on the surface of the crushing blade disc 3, and the outer surface of the crushing box 1 corresponding to the positions of the two rotating cylinders 2 is provided with a driving mechanism 7, and the two driving mechanisms 7 are used to control the two rotating cylinders 2 to rotate in opposite directions, and a feed hopper 8 is fixedly installed on the top of the crushing box 1.

[0024] like Figures 2 to 6As shown, the guide assembly 5 includes a fixed shaft 501, and the outer surface of the fixed shaft 501 is provided with wave grooves 502 corresponding to the positions of the plurality of crushing blade discs 3. The crushing box 1 is fixedly provided with brackets 101 at both ends of the fixed shaft 501. The fixed shaft 501 is fixedly installed between the two brackets 101. The wave groove 502 is formed by a plurality of arc-shaped protrusions staggered around the fixed shaft 501 to form a circle. The adjustment assembly 6 includes a screw 601 threadedly connected to the crushing blade teeth 4. The end of the screw 601 close to the fixed shaft 501 is threadedly connected to the guide rod 602. The end of the guide rod 602 away from the screw 601 is slidably arranged inside the wave groove 502, as shown in FIG. Figures 6 to 8 As shown, a ball 6021 is provided at one end of the guide rod 602 away from the screw 601 , and the friction between the guide rod 602 and the wave groove 502 can be reduced by using the provided ball 6021 .

[0025] like Figures 3 to 7 As shown, both the rotating cylinder 2 and the shredding blade disc 3 are polygonal, the number of edges and corners of the shredding blade disc 3 is greater than the number of edges and corners of the rotating cylinder 2, and a polygonal docking groove 302 with the same number of edges and corners as the rotating cylinder 2 is provided at the center of the shredding blade disc 3. The number of edges and corners of the shredding blade disc 3 is greater than the number of edges and corners of the rotating cylinder 2, so that the shredding teeth 4 on two adjacent shredding blade discs 3 can be staggered or irregularly installed, and the irregular distribution of the shredding teeth 4 can cause the paper to fluctuate, thereby improving the feeding speed and the shredding effect; a rotating hole 201 adapted to the fixed shaft 501 is provided at the center of the rotating cylinder 2, and sealed bearings are provided at both ends of the rotating hole 201, so that when the rotating cylinder 2 rotates, its friction force can be reduced, and the stability of the rotating cylinder 2 during rotation is improved. Lubricating liquid is provided between the rotating cylinder 2 and the fixed shaft 501, so that the friction force between the guide rod 602 and the wave groove 502 can be further reduced during use.

[0026] like Figure 5 and Figure 6 As shown, movable grooves 9 are provided at positions of the rotating cylinder 2 and the crushing blade disc 3 corresponding to the guide rod 602 , and the movement of the guide rod 602 can be constrained by the provided movable grooves 9 .

[0027] like Figures 1 to 3 As shown, the driving mechanism 7 includes a driving member 701 fixedly mounted on the side of the pulverizing box 1, and a pulley 702 is fixedly provided at the output end of the driving member 701 and the end of the rotating cylinder 2. The two pulleys 702 are connected by a transmission belt 703. The driving member 701 drives one of the pulleys 702 to rotate, and then the rotating pulley 702 drives the other pulley 702 to rotate through the transmission belt 703, so that the following pulley 702 drives the rotating cylinder 2 to rotate. At the same time, the cooperation between the two driving members 701 can control the two rotating cylinders 2 to rotate in opposite directions.

[0028] The driving mechanism 7 and the sealed bearing described in the present application are well-known technologies in the technical field, so their specific structures and working principles are not described in detail.

[0029] The working process is as follows: S1, such as Figures 1 to 3 As shown, during pulverization, by starting the driving member 701, the driving member 701 drives one of the pulleys 702 to rotate, and then the rotating pulley 702 drives the other pulley 702 to rotate through the transmission belt 703, so that the following pulley 702 drives the rotating drum 2 to rotate, and at the same time, by using the cooperation between the two driving members 701, the two rotating drums 2 can be controlled to rotate in opposite directions; S2, such as Figures 4 to 6 As shown, when the rotating drum 2 rotates, the polygonal docking groove 302 is used to make the multiple crushing blades 3 rotate along with the rotating drum 2; S3, such as Figures 4 to 6 As shown, when the crushing blade disc 3 rotates with the rotating cylinder 2, the screw 601 drives the crushing blade teeth 4 to slide axially back and forth on the surface of the crushing blade disc 3 (as shown in FIG. Figure 5 and Figure 7 As shown, the crushing blade 3 rotates with the rotating cylinder 2, while the fixed shaft 501 is fixed and does not rotate. For example, the wave groove 502 arranged on the fixed shaft 501 is composed of a groove and a plurality of arc-shaped protrusions arranged alternately. When the rotating cylinder 2 rotates, the guide rod 602 moves in the groove. When the guide rod 602 contacts one of the arc-shaped protrusions, the guide rod 602 is pushed by the arc-shaped protrusion, as shown in FIG. Figure 5 As shown, the guide rod 602 will slide to the right side of the crushing blade disc 3. When the guide rod 602 cooperates with another arc-shaped protrusion arranged in a staggered manner, the guide rod 602 will be pushed to the other side by the other arc-shaped protrusion, as shown in FIG. Figure 5 As shown, the guide rod 602 will slide to the left side of the crushing blade disc 3. In summary, by using a plurality of staggered arc-shaped protrusions, the crushing blade disc 3 can rotate with the rotating cylinder 2 for one circle, so that the screw 601 drives the crushing teeth 4 to slide axially back and forth on the surface of the crushing blade disc 3). Figure 1 As shown, at this time, the scraps generated during the production of corrugated paper boxes can be put into the crushing box body 1 from the feed hopper 8; S4, such as Figure 5 and Figure 6 As shown, the axial reciprocating sliding of the shredding teeth 4 can increase the chance of contact with the paper, making the shredding action more frequent and effective, while having the effects of shredding and cross-cutting, thereby improving the shredding capacity of the device; S5, such as Figure 5 and Figure 6As shown, the axial sliding of the shredding teeth 4 helps the paper to be more evenly distributed around the shredding disc 3 during the shredding process, thereby avoiding uneven shredding caused by paper position deviation or different thickness; S6, such as Figure 5 and Figure 6 As shown, the reciprocating axial sliding of the shredder teeth 4 helps to push the paper into the shredder, which can reduce the blockage or paper jam caused by paper accumulation, and because the paper contacts the shredder teeth 4 more evenly during the shredding process, it helps to reduce the single point wear of the blade, thereby extending the service life of the blade; S7, such as Figure 1 and Figure 2 As shown, the irregular distribution of the shredding teeth 4 can cause the paper to fluctuate, thereby improving the feeding speed and the shredding effect.
