[0029] like Figures 1 to 5 As shown in the figure, this embodiment provides a pulper for paper production. The pulper includes a crushing box 1 and a shredding box 2 fixed to the bottom of the crushing box 1. A motor 3 is fixedly connected to one side of the crushing box 1. A rotating shaft 4 is rotatably connected inside the crushing box 1. There are two sets of rotating shafts 4. A pulley 5 is provided on one side of the crushing box 1. One end of each set of rotating shafts 4 extends to the outside of the crushing box 1 and is fixedly connected to the pulley 5. The output end of the motor 3 is fixedly connected to one set of rotating shafts 4. The two sets of pulleys 5 are connected by a transmission belt 6. The transmission belt 6 is in the shape of an 8. The figure-8 shaped transmission belt 6 can make the two sets of rotating shafts 4 rotate synchronously inward, thereby speeding up the paper crushing operation.
[0030] Eccentric wheel blades 7 are mounted on the surface of the rotating shaft 4. The eccentric wheel blades 7 are arranged at equal intervals, with four eccentric wheel blades 7 forming a group. The four eccentric wheel blades 7 are offset in the directions of up, down, left, and right respectively. At the same time, the eccentric wheel blades 7 on the surfaces of the two groups of rotating shaft 4 are arranged in a cross pattern. By grouping and arranging the eccentric wheel blades 7 in different directions, it is beneficial to improve cutting efficiency and accelerate paper cutting speed, thereby improving the production efficiency of the equipment.
[0031] A motor 8 is fixedly connected to the bottom of the crushing box 2. A rotating rod 9 is provided inside the crushing box 2. Both ends of the rotating rod 9 are rotatably connected to positioning rings 12. Both ends of the positioning rings 12 are fixedly connected to the crushing box 2. The output end of the motor 8 extends into the interior of the crushing box 2 and is fixedly connected to the rotating rod 9. The motor 8 is used to drive the rotating rod 9 to rotate. The positioning rings 12 can provide support force for the rotating rod 9 and maintain its stability.
[0032] The surface of the rotating rod 9 is fixedly connected with a long cutter 10 and a curved cutter 11. The long cutter 10 is located at the bottom of the curved cutter 11. Both the long cutter 10 and the curved cutter 11 are arranged in a circular array. The arrangement of the two can further break the paper. With the use of the eccentric wheel blade 7, the paper can be broken more completely, thereby improving the uniformity of the pulp.
[0033] A connecting rod 13 is also fixedly connected to the outer surface of the rotating rod 9. The connecting rod 13 is located at the top of the bending cutter 11. A scraper 14 is fixedly connected to the end of the connecting rod 13 away from the rotating rod 9. The scraper 14 is triangular in shape and fits against the inner side of the crushing box 2, which can prevent paper residue from remaining on the inner wall of the crushing box 2, thereby improving the utilization rate of paper.
[0034] A conveying pipe 15 is fixedly connected to one side of the crushing box 2. A water pump 16 is installed on the conveying pipe 15. A filter box 17 is installed at the end of the conveying pipe 15 away from the crushing box 2. A drain pipe 24 is installed at the other end of the filter box 17, which can facilitate the conveying of the crushed product to the inside of the filter box 17 for filtration.
[0035] A baffle 18 is installed on one side of the filter box 17. A first filter plate 20 and a second filter plate 21 are fixedly connected to the inside of the baffle 18. Both the first filter plate 20 and the second filter plate 21 are located inside the filter box 17. The first filter plate 20 is located on one side of the second filter plate 21. The filter screens inside the first filter plate 20 and the second filter plate 21 are a coarse filter screen and a fine filter screen, respectively. The first filter plate 20 can intercept large particles of impurities, and the second filter plate 21 can intercept small particles of impurities, thereby reducing the wear of the equipment.
[0036] Both sides of the baffle 18 are fixedly connected with trapezoidal strips 19. The inner side of the filter box 17 is provided with a trapezoidal groove 22. The trapezoidal strips 19 are located inside the trapezoidal groove 22 and are movably connected to it. The end of the baffle 18 away from the filter box 17 is fixedly connected with a handle 23 to facilitate the driving of the baffle 18. At the same time, a magnetic block is installed at one end of the inner side of the trapezoidal groove 22, and an iron block is installed at the end of the trapezoidal strip 19 away from the baffle 18. The two are magnetically connected, which can facilitate the positioning of the baffle 18. In addition, a sealing strip is installed on the inner side of the baffle 18, that is, the side close to the first filter plate 20 and the second filter plate 21, which can increase its sealing performance.
[0037] In use, the paper is placed on top of the shredder 1, and the motor 3 is started to drive a set of pulleys 5 and a set of rotating shafts 4 to rotate. The motor 3 then drives another set of rotating shafts 4 to rotate via the transmission belt 6. This causes the eccentric wheel blades 7 on the surfaces of the two sets of rotating shafts 4 to rotate inward synchronously. By grouping and arranging the eccentric wheel blades 7 in different directions, the cutting efficiency is improved and the paper cutting speed is accelerated, thereby improving the production efficiency of the equipment. Furthermore, since the eccentric wheel blades 7 on the two sets of rotating shafts 4 are staggered, the error in paper sampling can be reduced, ensuring the accuracy of each sampling.
[0038] The shredded paper will naturally fall into the crushing box 2. At this time, the motor 8 is started to drive the rotating rod 9 to rotate. The rotating rod 9 drives the long blade 10, the curved blade 11 and the scraper 14 to rotate synchronously to speed up the paper crushing operation. At the same time, it can make the paper crushed more evenly. In summary, the degree of paper crushing is more refined and the crushed particles are more uniform and smaller. This makes the paper easier to process in subsequent production processes and can also improve production efficiency.
[0039] Subsequently, water is filled into the crushing box 2 and mixed through a structure such as the rotating rod 9. Finally, the water pump 16 is started to make the slurry flow along the inside of the conveying pipe 15 into the filter box 17. The first filter plate 20 and the second filter plate 21 inside the filter box 17 can intercept particulate impurities and suspended matter, while also reducing the wear of these particles on the equipment. They can also be quickly inspected and replaced, thus avoiding the phenomenon of the first filter plate 20 and the second filter plate 21 becoming clogged due to long-term use.

Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
