[0026] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model with reference to the accompanying drawings of the specification.

[0027] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Embodiment 1

[0029] Referring to Figures 1-4 , for the first embodiment of the present utility model, a pulp production line for corrugated core paper is provided, including a base 1 and an adjusting assembly 2 arranged at the upper end of the base 1. An upper end of the adjusting assembly 2 is provided with a crushing box 3. A crushing assembly 4 is arranged inside the middle end of the crushing box 3. A pre-crushing assembly 5 is arranged on one side of the upper end of the crushing assembly 4. A feed inlet 12 is opened at the upper end of the crushing box 3. A discharge outlet 13 is opened at one end of the crushing box 3 away from the feed inlet 12;

[0030] The crushing assembly 4 includes two groups of rotating shafts 41 symmetrically arranged inside the crushing box 3. The pre-crushing assembly 5 includes a turntable 51 arranged at the upper end of one of the rotating shafts 41. Protrusions 52 are arranged on the upper end surface of the turntable 51. An adjusting plate 53 is sleeved on the outer wall of the protrusions 52. One side of the adjusting plate 53 is connected with a cutting knife 55 through a second slide bar 54. The upper end of the crushing box 3 is connected with a fixed plate 56. A second slide sleeve 57 is arranged at the lower end of the fixed plate 56.

[0031] The lower ends of two groups of rotating shafts 41 are rotatably connected to the crushing box 3. The crushing assembly 4 further includes a second motor 42 disposed at the lower end of the crushing box 3, and the output end of the second motor 42 is fixedly connected to one group of rotating shafts 41. A spiral blade 43 is disposed on the outer wall of the rotating shaft 41. The upper end of the rotating shaft 41 movably passes through the crushing box 3 and a transmission wheel 44 is fixedly sleeved on the outer wall. The outer wall of the transmission wheel 44 is wrapped with a transmission belt 45, and the two transmission wheels 44 are drivingly connected through the transmission belt 45.

[0032] The protrusion 52 is disposed at an eccentric position away from the center of the turntable 51. The protrusion 52 is movably inserted into the inner wall of the adjusting plate 53. The second sliding sleeve 57 is movably sleeved on the outer wall of the second sliding rod 54. A cutting groove 6 matching the cutter 55 is formed on one side of the upper outer wall of the crushing box 3.

[0033] The waste paper to be crushed enters the crushing box 3 through the feed port 12. The second motor 42 is started to drive one group of rotating shafts 41 to rotate. The rotating shaft 41 can drive the other group of rotating shafts 41 to rotate through the drive of the transmission wheel 44 and the transmission belt 45. Thus, the two rotating shafts 41 drive the spiral blades 43 to rotate. While the rotating shaft 41 rotates, it drives the turntable 51 to rotate. Thus, the turntable 51 drives the protrusion 52 to slide along the inner wall of the adjusting plate 53. Since the second sliding sleeve 57 is slidably sleeved on the outer wall of the second sliding rod 54, under the drive of the turntable 51 and the protrusion 52, the adjusting plate 53 drives the second sliding rod 54 to periodically move back and forth along the second sliding sleeve 57. Thus, the cutter 55 periodically moves back and forth along the cutting groove 6 to pre-crush the waste paper falling into the crushing box 3 from the feed port 12, so that the larger waste paper is cut into small pieces. The small pieces of waste paper are guided by the inclined surface at the lower end of the inner wall of the crushing box 3 to move to the spiral blade 43 for secondary crushing. After successive pre-crushing and secondary crushing, the crushing effect of the waste paper is better, avoiding uneven dispersion of the subsequent pulp due to poor crushing effect and making the quality of the pulp higher.

[0034] Embodiment 2

[0035] Refer to Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the adjusting assembly 2 includes two groups of support rods 21 symmetrically disposed on one side of the upper end of the base 1. The crushing box 3 is rotatably connected to the support rods 21. A first motor 22 is disposed on the outer wall of one side of the base 1. The output end of the first motor 22 is connected to a ball screw 23, and the end of the ball screw 23 away from the first motor 22 is rotatably connected to the base 1. A ball screw sleeve 24 is movably sleeved on the outer wall of the ball screw 23;

[0036] The adjusting assembly 2 further includes a first sliding rod 25 fixedly arranged on one side of the upper end of the base 1 and symmetric to the ball screw 23. A first sliding sleeve 26 is movably sleeved on the outer wall of the first sliding rod 25. Adjusting rods 27 are hingedly connected to the upper ends of the ball screw sleeve 24 and the first sliding sleeve 26, and the upper ends of the adjusting rods 27 are rotatably connected to the outer wall of the lower end of the crushing box 3.

[0037] A filter plate 7 is movably sleeved on the outer wall of the crushing box 3 at one end of the discharge port 13. Bolts 8 are threadedly inserted into the upper and lower ends of the filter plate 7. The bolts 8 movably pass through the crushing box 3, and insertion holes matching the bolts 8 are formed in the upper and lower ends of the crushing box 3.

[0038] A blower 9 is fixedly arranged on one side of the outer wall of the crushing box 3 at the lower end of the feed port 12. The air outlet end of the blower 9 is connected to an air pipe 10, and one end of the air pipe 10 away from the blower 9 passes through the crushing box 3.

[0039] A water pipe 11 is fixedly inserted into one side of the upper end of the crushing box 3. One end of the water pipe 11 is located inside the crushing box 3. The crushing box 3 is arranged in a downward-inclined L-shaped structure, and an inclined surface is arranged on the inner wall of the crushing box 3 at the lower end of the feed port 12.

[0040] To avoid the accumulation of shredded paper after preliminary crushing at the lower end of the feed port 12, the first motor 22 can be started to drive the ball screw 23 to rotate. The ball screw 23 drives the ball screw sleeve 24 to move, so that the angle between the adjusting rod 27 and the ball screw 23 becomes larger. And the upper end of the support rod 21 is rotatably connected to the outer wall of the front end of the crushing box 3. Thus, the adjusting rod 27 jacks up the crushing box 3 upward, so that the front end of the crushing box 3 inclines downward along the support rod 21. And the blower 9 is started to blow air toward the spiral blade 43 through the air pipe 10. Thus, under the action of gravity and the force of the air flow, the shredded paper slides downward along the crushing box 3 to the spiral blade 43 for secondary crushing. After the crushing is completed, the shredded paper scraps that meet the size pass through the filter plate 7 and are discharged from the discharge port 13, and the paper scraps that do not meet the size and are larger are intercepted by the filter plate 7. At this time, the first motor 22 can be started to rotate in the reverse direction, so that the angle between the adjusting rod 27 and the ball screw 23 becomes smaller, so that the paper scraps that do not meet the size slide to the spiral blade 43 again for crushing. The above operations are repeated until all the waste paper entering the crushing box 3 is completely crushed and discharged from the filter plate 7. When it is necessary to disassemble and clean the filter plate 7, the bolts 8 can be rotated to take it out, so as to facilitate the disassembly of the filter plate 7. After the crushing is completed, the water source can be externally connected through the water pipe 11, and the water flow passes through the crushing box 3 to clean the inside of the crushing box 3.

[0041] The remaining structures are the same as those of Embodiment 1.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
