[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0036] The terms “left,” “right,” “front,” “back,” “up,” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0037] Example 1

[0038] In some embodiments, please refer to the appendix of the specification. Figure 1-3 , a uniformly crushed pulp comminution device, comprising a box 1;

[0039] A mounting frame 11 is fixedly installed on the left side of the box body 1, a feeding port 12 is provided on the upper side of the box body 1, a first discharge port is provided in the middle of the right side of the box body 1, a first discharge chute 13 is fixedly installed in the middle of the right side of the box body 1, the first discharge chute 13 is located below the first discharge port, and a second discharge port 14 is provided at the bottom of the box body 1; a crushing mechanism 2 is installed inside the box body 1 and on the mounting frame 11, and a material dividing assembly 3 is installed in the middle of the box body 1;

[0040] The crushing mechanism 2 includes a first crushing mechanism 21 and a second crushing mechanism 22, which are installed inside the box 1 and on the mounting frame 11. The first crushing mechanism 21 is located on the upper side of the second crushing mechanism 22, and the material dividing assembly 3 is located between the first crushing mechanism 21 and the second crushing mechanism 22; a material shifting assembly 4 is installed on the box 1, the mounting frame 11 and the first crushing mechanism 21.

[0041] In this embodiment, when the uniformly crushed pulp crushing equipment is working normally, the first discharge trough 13 is closed, and the coarse pulp is fed into the interior of the box body 1 from the feeding port 12, and the coarse pulp falls onto the first crushing mechanism 21. The coarse pulp is preliminarily crushed by the first crushing mechanism 21, and the crushed pulp falls onto the dividing component 3; the dividing component 3 filters the pulp, so that the insufficiently crushed pulp particles are larger and fall to the upper side of the dividing component 3, and the fully crushed pulp particles are smaller and fall to the inside of the dividing component 3. When there is more fully crushed pulp in the dividing component 3, the first discharge trough 13 is opened. The discharging trough 13 allows the pulp with smaller particle size after preliminary crushing to be discharged from the first discharging trough 13; then the first crushing mechanism 21 drives the material shifting component 4 to shift the insufficiently crushed pulp on the upper side of the material distribution component 3 to the upper side of the second crushing mechanism 22, and the insufficiently crushed pulp is crushed again by the second crushing mechanism 22. After the crushing is completed, the pulp is discharged through the second discharging port 14; thereby ensuring uniform pulp crushing, avoiding secondary crushing of pulp that has been sufficiently crushed for the first time, avoiding excessive crushing of pulp that has been sufficiently crushed, and damaging the fibers of the pulp; thus ensuring the crushing quality of the pulp.

[0042] Example 2

[0043] In some embodiments, as Figure 1-7 As shown, as a preferred embodiment of the present invention, the first crushing mechanism 21 includes a reduction motor 211, a first gear 212, a second gear 213, a rotating shaft 214, a cutting blade 215 and a fixed block 216. The two rotating shafts 214 are symmetrically mounted on the inside of the box body 1 for rotation front and back; a plurality of cutting blades 215 are fixedly mounted on the rotating shaft 214 at equal intervals; a plurality of fixed blocks 216 are symmetrically fixedly mounted on the inner wall of the box body 1 at equal intervals; the fixed block 216 slides in contact with the cutting blades 215; the left end of the front rotating shaft 214 passes through the box body 1 and is fixedly connected to the second gear 213, and the left end of the rear rotating shaft 214 passes through the box body 1 and is fixedly connected to the first gear 212; the first gear 212 is meshed with the second gear 213; the reduction motor 211 is fixedly mounted on the left side of the mounting frame 11, and the output end of the reduction motor 211 passes through the mounting frame 11 and is fixedly connected to the first gear 212;

[0044] The second crushing mechanism 22 has the same structure as the first crushing mechanism 21 but is located in a different position;

[0045] The material distribution assembly 3 includes a curved filter plate 31 and a material drop chute 32. The left and right sides of the curved filter plate 31 are fixedly mounted on the inner wall of the box body 1. The left and right sides of the material drop chute 32 are fixedly mounted on the inner wall of the box body 1. The material drop chute 32 is located below the curved filter plate 31, and the left end of the material drop chute 32 is higher than the right end. The right end of the material drop chute 32 is aligned with the first discharge chute 13. The two side walls of the material drop chute 32 in the front-to-back direction are spaced apart from the two inner side walls of the box body 1 in the front-to-back direction. There is also a space between the two side walls of the curved filter plate 31 in the front-to-back direction and the two inner side walls of the box body 1 in the front-to-back direction. That is, the vertical projections of the material drop chute 32 and the curved filter plate 31 are both located on the second crushing mechanism 22. This allows the material distribution assembly 4 to distribute the material in the front-to-back direction, so that large particles of paper scraps fall into the second crushing mechanism 22 through the two gaps.

[0046] The material distribution assembly 3 also includes a water injection trough 33, which is fixedly installed in the middle of the left side of the box body 1. The water outlet of the water injection trough 33 passes through the left side wall of the box body 1 and is located above the left end of the blanking chute 32, so that the water in the water injection trough 33 flows into the blanking chute 32;

[0047] The material shifting assembly 4 includes a shifting assembly and a transmission assembly. The shifting assembly is mounted on the housing 1. The second gear 213 is driven and connected to the shifting assembly via the transmission assembly so that the shifting assembly shifts the material on the arc-shaped filter plate 31 in a target direction. Specifically, the target direction in this embodiment is the front-to-back direction of the housing 1.

[0048] The toggle assembly is used to toggle the large-particle paper scraps located above the arc-shaped filter plate 31 toward the front and rear side walls of the box body 1 so that the paper scraps fall onto the second shredding mechanism 22; the transmission assembly is mounted on the second gear 213 and the mounting frame 11; the transmission assembly is drivingly connected to the toggle assembly;

[0049] The toggle assembly includes a moving rod 41, a material-selecting tooth 42, a slider 43 and a slide 44. The slide 44 is opened on the left and right sides of the box body 1. The moving rod 41 extends from the left side to the right side of the box body 1. The extension direction of the slide 44 is the same as the shape of the longitudinal section of the arc-shaped filter plate 31. A slider 43 is slidably installed in the slide 44. The two sliders 43 are fixedly installed on both sides of the same moving rod 41. A plurality of material-selecting teeth 42 are fixedly installed at equal intervals on the lower side of the moving rod 41; the material-selecting teeth 42 are located on the upper side of the arc-shaped filter plate 31.

[0050] The transmission assembly includes a shift rod 45, a limiting groove 46 and a rotating rod 47. The middle part of the shift rod 45 is rotatably mounted on the inner side of the mounting frame 11, the upper end of the shift rod 45 is rotatably connected to one end of the rotating rod 47, and the other end of the rotating rod 47 is rotatably mounted on the edge of the second gear 213; a limiting groove 46 is provided on the lower side of the shift rod 45, and the limiting groove 46 is slidably connected to the left end of the moving rod 41.

[0051] In this embodiment, when the pulverizing mechanism 2, the material dividing assembly 3, and the material shifting assembly 4 are operating normally, the reduction motor 211 drives the first gear 212 to rotate, and the first gear 212 drives the second gear 213 to rotate. The rotation of the first gear 212 and the second gear 213 drives the two rotating shafts 214 to rotate in opposite directions, thereby driving the two cutting blades 215 to rotate in opposite directions, so that the pulp is pulverized by the two sets of cutting blades 215.

[0052] The crushed pulp is blocked by the fixed block 216 and falls onto the upper side of the curved filter plate 31. The coarser pulp particles are blocked by the curved filter plate 31 and remain on the upper side of the curved filter plate 31. The finer pulp particles pass through the curved filter plate 31 and fall into the chute 32.

[0053] At the same time, water can be injected into the material chute 32 through the water injection trough 33, so that the pulp in the middle of the material chute 32 and the arc filter plate 31 is immersed in water, which facilitates the separation and movement of the pulp.

[0054] At the same time, the second gear 213 rotates to drive the rotating rod 47 to move, and the rotating rod 47 drives the shifting rod 45 to swing, and the shifting rod 45 drives the moving rod 41 to move through the limiting groove 46 on the lower side. The moving rod 41 moves on the upper side of the arc filter plate 31 under the limiting action of the slider 43 and the slide groove 44, so that the pulp remaining on the arc filter plate 31 is shifted from the front and rear sides of the arc filter plate 31 to between the cutting blades 215 on the lower side through the shifting teeth 42 on the lower side of the moving rod 41 for re-crushing.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
