[0001] The present application relates to the technical field of papermaking, and in particular to a broken paper pulping device. Background Art

[0002] In the current papermaking process, plant fibers are crushed into pulp, and then the pulp is processed through a series of processes to form paper. In the process of paper production, the formed paper is transported and inspected before being rolled up and packaged. In order to pass the inspection during transportation, the fractures and cracks of the formed paper are screened to screen out the unqualified paper and then cut for recycling.

[0003] Related technologies such as a working system of a damaged paper pulping equipment disclosed in publication number CN112047153A include a damaged paper pulping machine body, a paper winder, a paper detection sensor 1, a processing module, a driving module 1, a paper detection sensor 2, a transmission distance detection module, a driving module 3 and an image acquisition and verification module. The paper winder is provided with a cutting mechanism 1, a feeding port 1, a feeding port 2, a cutting mechanism 2 and a paper feeding port. The damaged paper pulping machine equipment includes a damaged paper pulping machine body, a damaged paper pulping machine body is provided with a damaged paper pulping chamber and a vortex generating device. The damaged paper pulping machine body is connected to a liquid extraction pump. The vortex generating device includes a stirring rotor and a stirring motor. The damaged paper pulping machine body is provided with a flushing device. The damaged paper pulping machine body is provided with a reflux pipe. The reflux pipe and the liquid outlet pipe are both provided with solenoid valves.

[0004] The inventor believes that when the cut broken paper is recycled, the broken paper enters the broken paper pulping chamber and is soaked and softened by water, and then the soaked broken paper is split under stirring, and then gradually dispersed in the water to form a slurry, which makes it take a long time for the broken paper to be recycled to form a slurry, resulting in a low broken paper recycling efficiency. Summary of the invention

[0005] In order to improve the broken paper recovery efficiency, the purpose of the present application is to provide a broken paper pulping device.

[0006] The broken paper pulping equipment provided in this application adopts the following technical solution:

[0007] A broken paper pulping device comprises a pulping box and a conveying mechanism arranged on the pulping box to output pulp, the pulping box is provided with a feeding port for broken paper to fall into, the pulping box has side-by-side rotatable paper shredding rollers located below the feeding port, the pulping box is provided with a driving member for driving the paper shredding rollers to rotate, and the meshing part between the paper shredding rollers is located directly below the feeding port.

[0008] By adopting the above technical solution, when the broken paper is recycled, the cut broken paper falls into the pulp box, and then falls into the shredding rollers after passing through the drop port. The driving part is started, driving the shredding rollers to rotate to break the broken paper that enters between the shredding rollers, so that the broken paper is broken into small pieces of paper, so as to speed up the dissolution rate of the broken paper in the pulp box, and then speed up the formation of pulp liquid. Finally, the conveying mechanism is started to convey the formed slurry so that it can be reused to form a complete paper. Therefore, by setting the shredding roller, the broken paper entering the pulp box is first broken by the shredding roller and then dissolved, which speeds up the dissolution rate of the broken paper in the pulp box, shortens the time for the broken paper to form slurry, improves the recycling efficiency of the broken paper, reduces the waste of paper resources, and achieves the effect of energy saving and environmental protection.

[0009] Optionally, a plurality of notches are formed on the shredding roller, and a convex portion is formed between two adjacent notches, and the notches are used for the convex portion on another shredding roller to be embedded in and engage with each other.

[0010] By adopting the above technical solution, when the broken paper is broken, the broken paper enters the meshing position of the recess and the protrusion, so that the broken paper is crushed by the meshing of the recess and the protrusion, further reducing the area of ​​the broken paper and improving the dispersion of the broken paper, which is conducive to the dissolution of the broken paper in water to form pulp.

[0011] Optionally, a plurality of hook blocks are arranged on the convex portion along its circumferential direction, and the hook blocks are bent in a direction facing the other shredding roller.

[0012] By adopting the above technical solution, when the broken paper is broken, the shredding rollers mesh with each other and rotate from top to bottom, and the hook block on the convex part rotates from top to bottom between the shredding rollers, so that the hook block breaks the broken paper after rotating in the notch. After the broken paper is broken, the hook block rotates from bottom to top from the other side of the shredding roller, so that the bent hook block scoops up the water in the pulp box and flows into the notch as the shredding roller rotates, so that the hook block and the notch between the broken paper rollers are filled with water, increasing the wetness between the hook block and the notch, reducing the accumulation or adhesion of broken paper pulp in the notch, thereby reducing the adhesion of paper pulp on the shredding roller.

[0013] Optionally, a slide plate located below the shredding roller is slidably arranged in the pulp box, an elastic member for pushing the slide plate to slide is arranged in the pulp box, a plurality of slide bars are arranged at one end of the slide plate away from the elastic member, a brush is arranged at the end of the slide bar close to the slide plate, and the brush slides and abuts against the convex part at the bottom of the shredding roller.

[0014] By adopting the above technical solution, when the shredding roller shreds damaged paper, the slide plates are moved away from each other to compress the elastic member. Then the slide plates are released, so that the slide plates slide back and forth under the shredding roller under the action of the elastic member, thereby driving the brush on the slide bar to slide back and forth. That is, the brush slides back and forth to abut against the hook block on the convex part, so as to clean the gap between the hook block and the convex part, thereby reducing the accumulation of pulp in the gap between the hook block and the convex part.

[0015] Optionally, the initial position of the brush is located on the side where the shredding rollers are away from each other.

[0016] By adopting the above technical solution, when the slide plate slides, the brush slides back and forth from the side of the shredding rollers that are away from each other toward the middle of the shredding rollers, so as to avoid the brush being located between the shredding rollers to hinder the falling of the broken paper after being broken, and reduce the obstacle of the brush to the sinking of the broken paper in the pulping box, so as to facilitate the broken paper after being broken to be fully dissolved in various places in the pulping box.

[0017] Optionally, the slide plates are spaced apart from each other, and slide grooves are formed between the slide plates, and the slide grooves are used for slide bars on adjacent slide plates to slide into.

[0018] By adopting the above technical solution, when the slide plate slides and drives the brush to clean the protrusion and the hook block, the slide plate slides back and forth continuously under the shredding roller under the elastic force of the elastic member, so that the two slide plates under the shredding roller are moved closer to or away from each other, so that the slide bar slides in the slide groove, and the slide groove provides space for the slide bar to slide, so that the slide bar drives the brush to slide back and forth under the shredding roller.

[0019] Optionally, the slide plate slides in a direction perpendicular to the rotation axis of the shredding roller, and a hook groove is provided on the slide bar for the hook block to rotate into and abut against. After the hook block rotates out of the hook groove, it drives the slide plate to slide back and forth under the action of the elastic member.

[0020] By adopting the above technical solution, when the shredding roller shreds damaged paper, the hook block rotates from top to bottom between the shredding rollers as the shredding roller rotates, until the hook block rotates to the bottom of the shredding roller, and then the hook block rotates into the hook groove. The hook block pushes against the wall of the hook groove to drive the slide bar and the slide plate to slide toward the inner wall of the pulp box, so that the elastic member is compressed. After the hook block rotates upward over the bottom of the shredding roller, the hook block is separated from the slide bar, so that the elastic force of the elastic member acts on the slide plate, driving the slide plates to move closer or farther from each other, so that the brush slides back and forth to contact the hook block and the convex part, and cleans the hook block and the convex part. At the same time, the slide bar slides back and forth in the slide groove, so that the sliding of the slide plate is driven by the shredding roller, reducing the additional driving source, so that the slide plate is driven by the shredding roller and slides back and forth under the elastic force of the elastic member.

[0021] Optionally, the shredding roller is coaxially connected with gears that mesh with each other.

[0022] By adopting the above technical solution, when the shredding rollers are driven to rotate, the driving member starts to drive one of the shredding rollers to rotate, and one of the shredding rollers drives the other shredding roller to rotate through the mutually meshing gears, thereby realizing the two shredding rollers rotating from top to bottom, so that both shredding rollers are driven, thereby increasing the shredding force of the shredding rollers.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] By setting up shredding rollers, the broken paper entering the pulping box is first broken by the shredding rollers and then dissolved, which speeds up the dissolution of the broken paper in the pulping box, shortens the time for the broken paper to be recycled and form pulp, improves the recycling efficiency of the broken paper, reduces the waste of paper resources, and achieves the effect of energy saving and environmental protection;

[0025] By setting a curved hook block, the curved hook block scoops up water in the pulp box and then flows into the notch as the shredding roller rotates, so that the hook block and the notch between the broken paper rollers are filled with water, increasing the wetness between the hook block and the notch, reducing the accumulation or adhesion of broken paper pulp in the notch, thereby reducing the adhesion of paper pulp on the shredding roller;

[0026] By providing a slide plate, a slide bar and a brush, the slide plate and the slide bar are driven to slide back and forth under the action of the elastic member, so that the brush slides back and forth and abuts against the hook block on the convex part, so as to clean the gap between the hook block and the convex part, thereby reducing the accumulation of pulp in the gap between the hook block and the convex part;

[0027] By providing a hook groove and utilizing the hook groove for the hook block to rotate in and out, the rotation of the shredding roller can drive the slide plates to move away from each other, so that the sliding of the slide plates is driven by the shredding roller, and the additional driving source is reduced, thereby facilitating the slide plates to be driven by the shredding roller and slide back and forth under the elastic force of the elastic member.

The water pump 32 is supplied with suction through the water tank 31, and a branch of the water outlet pipe 34 connected to the pulping box 1 forms a reflux, so as to dissolve the pulp repeatedly and improve the uniformity and concentration of the pulp.

[0036] Reference Figure 1 and Figure 2 A material drop opening 12 is provided at the lower end of the guide ring plate 11, and the guide ring plate 11 gradually shrinks downward in the vertical direction. The shredding mechanism 2 includes shredding rollers 21 rotatably connected in parallel with the pulp box 1, and a driving member 22 fixedly connected to the pulp box 1 to drive one of the shredding rollers 21 to rotate. The driving member 22 is a motor, and the meshing portion between the two shredding rollers 21 is located directly below the material drop opening 12.

[0037] Reference Figure 1 and Figure 2One end of the shredding roller 21 is also coaxially connected to a mutually meshing gear 23, and the gear 23 is located outside the pulping box 1, so that one of the shredding rollers 21 is driven to rotate by a motor, and the rotation direction between the two shredding rollers 21 is driven to rotate downward in the vertical direction under the meshing of the gear 23.

[0038] Reference Figure 2 A plurality of notches 211 are provided on the circumferential side wall of the shredding roller 21 along its axial direction, and a convex portion 212 is formed between two adjacent notches 211. The notches 211 are provided for the convex portions 212 on the adjacent shredding rollers 21 to be inserted into and mesh with each other, so that after the shredding roller 21 rotates, the convex portions 212 rotate in the notches 211 and mesh with each other.

[0039] Reference Figure 2 , a plurality of hook blocks 213 are fixedly connected to the convex portion 212 along its circumferential direction. In the embodiment of the present application, the number of hook blocks 213 is selected as four. The hook blocks 213 are all bent in the direction facing the other shredding roller 21, and the liquid level in the pulping box 1 submerges the bottom of the shredding roller 21. In order to facilitate the rotation of the shredding roller 21, the hook block 213 rotates upward after passing the bottom of the shredding roller 21 and holds part of the water until the hook block 213 rotates again above the shredding roller 21, and the water in the hook block 213 flows into the shredding roller 21 to moisten the shredding roller 21 and reduce the amount of damaged paper stuck in the notch 211.

[0040] Reference Figure 2 A fixed plate 4 corresponding to the shredding roller 21 is fixedly connected to the pulp box 1 below the shredding roller 21, and a slide plate 41 corresponding to the shredding roller 21 slides inside the fixed plate 4. The slide plate 41 slides below the shredding roller 21 in a direction perpendicular to the rotation axis of the shredding roller 21. The fixed plate 4 and the slide plate 41 are both located below the liquid surface in the pulp box 1.

[0041] Reference Figure 2 and Figure 3 The fixed plate 4 is provided with an elastic member 42 for pushing the sliding plate 41 to slide. The elastic member 42 is a plurality of springs fixedly connected to the fixed plate 4. One end of the spring away from the fixed plate 4 is fixedly connected to the sliding plate 41. One end of the sliding plate 41 away from the spring is fixedly connected to a plurality of slide bars 43. The slide bars 43 are spaced apart and evenly distributed.

[0042] Reference Figure 3 A slide groove 44 is formed between two adjacent slide bars 43. The slide bars 43 on the two slide plates 41 are staggered with each other. The slide groove 44 is for the slide bars 43 on the adjacent slide plates 41 to slide into, so that the slide plates 41 can drive the slide bars 43 to slide into the slide groove 44 under the elastic force of the spring, and when the spring is in a normal state, half of the length of the slide bar 43 is located in the slide groove 44.

[0043] Reference Figure 2 and Figure 3 The slide bar 43 corresponds to the convex part 212 on the shredding roller 21, and each slide bar 43 is located below the convex part 212. A brush 45 is fixedly connected to one end of the slide bar 43 close to the slide plate 41. The initial position of the brush 45 is located on the side of the shredding roller 21 away from each other, and the brush 45 slides against the convex part 212 and the hook block 213, so that the slide bar 43 slides by the spring to push the slide plate 41, so that the brush 45 slides back and forth to clean the convex part 212 and the hook block 213, so as to clean the damaged paper stuck between the hook block 213 and the convex part 212, and reduce the accumulation or adhesion of damaged paper in the hook block 213.

[0044] Reference Figure 2 and Figure 3 The slide plate 41 is provided with a hook groove 46 for the hook block 213 to rotate into. The depth of the bottom of the hook groove 46 is gradually reduced in the direction away from the slide plate 41. The hook block 213 rotates to the lowest point of the shredding roller 21 and rotates into the hook groove 46, and abuts against the groove wall of the hook groove 46 close to the spring, so as to push the slide plate 41 in the direction away from each other, so as to compress the spring. When the hook block 213 rotates upward with the rotation of the shredding roller 21, the hook block 213 is separated from the hook groove 46, so that the slide bar 43 is separated from the abutment of the hook block 213, and the spring elastic force acts on the slide plate 41, driving the slide bar 43 and the brush 45 to slide back and forth, so as to clean the hook block 213 and the protrusion 212.

[0045] Reference Figure 2 The bottom of the pulping box 1 is rotatably connected with a stirring vane 13, which is driven by a motor at the bottom of the pulping box 1 to stir the water in the pulping box 1 to form a water flow, so that the broken paper can be quickly dissolved in the water to form pulp.

[0046] The implementation principle of a broken paper pulping device in the embodiment of the present application is as follows: when the broken paper is recycled, the cut broken paper enters between the shredding rollers 21 from the drop port 12, and then the motor is started to drive the shredding rollers 21 to rotate in opposite directions, so as to break the broken paper entering between the shredding rollers 21. During the rotation of the shredding rollers 21, the hook block 213 rotates to the bottom of the shredding rollers 21 and then rotates into the hook groove 46, so as to push the groove wall of the hook groove 46 close to the slide plate 41 to push the slide bar 43 toward the spring, so that the spring is compressed. After the hook block 213 rotates away from the hook groove 46, the spring acts on the slide plate 41, and the slide plate 41 drives the slide bar 43 and the brush 45 to slide back and forth continuously under the shredding roller 21, so that the brush 45 continuously brushes the hook block 213 and the convex portion 212 back and forth, thereby reducing the accumulation of broken paper between the hook block 213 and the convex portion 212. It also speeds up the dissolution of broken paper after it is broken, shortens the time it takes to recover broken paper and form slurry, improves the recycling efficiency of broken paper, reduces the waste of paper resources, and achieves the effect of energy conservation and environmental protection.
