This includes various high-grade papers, yellow cardboard, waste cartons, trimming paper, baling paper, corporate and institutional paper, engineering paper, books, periodicals, and newspapers. Waste paper processing is the process of reprocessing recycled waste paper to obtain qualified fiber for the production of paper products. The recycling and utilization of waste paper benefits the environment, protects forests, and conserves resources. Waste paper can be reused multiple times. After recycling, waste paper products typically require shredding equipment used in waste paper recycling processes.

[0025] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-Figure 3 The present invention provides an embodiment of a waste paper recycling and processing pulverizing device, comprising:

[0027] The processing chamber 1 has two pulverizing rollers 5 rotatably connected to the middle end of the processing chamber 1, and a transmission gear 18 is located at the rear end of the two pulverizing rollers 5. The two transmission gears 18 are meshed with each other. The inner wall of the middle end of the processing chamber 1 is fixedly connected to a gear box 3. The two transmission gears 18 are arranged inside the gear box 3 to control the two pulverizing rollers 5 to pulverize the waste paper products. The bottom end of the processing chamber 1 is rotatably connected to a stirring shaft 7, a scraper 9 is located on the inner wall of the bottom side of the processing chamber 1, and one side of the scraper 9 is rotatably connected to a threaded rod 10. The threaded rod 10 is threadedly connected to the outer wall of the processing chamber 1. A plurality of nozzles 6 are provided on the inner wall of the processing chamber 1, and a water pipe 17 is provided at one end of the nozzle 6. The outer wall of the bottom end of the processing chamber 1 is fixedly connected to a discharge port 8, and the inner wall of the middle end of the processing chamber 1 is fixedly connected to a guide plate 4;

[0028] Specifically, the engagement between the two transmission gears 18 drives the rotation of the two shredding rollers 5 to achieve shredding of the waste paper. The gear box 3 arranged outside the two transmission gears 18 can prevent waste paper from being stuck between the two transmission gears 18. At the same time, the guide plate 4 can accurately place the waste paper on top of the two shredding rollers 5. The shredded waste paper is wetted by the nozzle 6 and the water pipe 17, and the wet waste paper is stirred into pulp by the stirring shaft 7. The pulp inside is discharged through the discharge port 8. At the same time, the movement of the scraper 9 inside the processing chamber 1 can be controlled by rotating the threaded rod 10, so that the pulp on the inner wall of the bottom side of the processing chamber 1 can be cleaned by the scraper 9 to avoid sticking to the inner wall of the processing chamber 1 and affecting the discharge of the pulp.

[0029] Reference Figure 1 、 Figure 3 and Figure 4 , two telescopic rods 2, one end of the telescopic rod 2 is fixedly connected to the inner wall of the top side of the processing chamber 1, and the other end of the telescopic rod 2 is fixedly connected to a cone head 13, a half gear 11 is located at the top of the processing chamber 1, and a tooth plate 12 is fixedly connected to the top side of the cone head 13. The tooth plate 12 and the half gear 11 are meshed and connected to control the lifting of the cone head 13. The rear end of one of the crushing rollers 5 and the rear end of the stirring shaft 7 are fixedly connected to a pulley 2 16, a pulley 15 is located at the rear end of the half gear 11, and the outer wall of the pulley 15 and the outer wall of the pulley 2 16 are connected by a belt. The outer wall of the rear side of the processing chamber 1 is installed with a motor 14 through a fixed bracket, and the driving end of the motor 14 is fixedly connected to the rear side of the pulley 15;

[0030] Specifically, the telescopic rod 2 can ensure that the cone head 13 moves up and down at the top of the processing chamber 1, and then through the engagement between the rotating half gear 11 and the tooth plate 12, when the half gear 11 is no longer engaged with the tooth plate 12, the spring inside the telescopic rod 2 can pull the cone head 13 up, and at the same time, the half gear 11 rotates one circle and engages with the tooth plate 12 again to control the lifting and lowering of the cone head 13, so that the waste paper spread on the two crushing rollers 5 can be bent by the downward pressing cone head 13. At the same time, when bending the waste paper, the cone head 13 will not contact the two crushing rollers 5, so that the waste paper can be better bent and crushed. At the same time, the rotation of the pulley 1 15 is controlled by the drive of the motor 14, and the belt drives the rotation of the other two pulleys 16, thereby controlling the rotation of one of the crushing rollers 5 and the rotation of the stirring shaft 7. The crushing, stirring and bending of the waste paper can be achieved by a single motor 14, which is convenient for saving work costs.

[0031] Working principle: First, the waste paper is put into the space between the two shredding rollers 5 through the guide plate 4, and then the starting motor 14 drives the rotation of the pulley 1 15 to cooperate with the belt to control the rotation of the other two pulleys 2 16, so that the motor 14 drives the rotation of the half gear 11, one of the shredding rollers 5 and the stirring shaft 7. The engagement between the rotating half gear 11 and the tooth plate 12 is used to control the lifting and lowering of the cone head 13, thereby bending the waste paper flattened on the two shredding rollers 5. At the same time, the rotating shredding roller 5 drives the rotation of the two shredding rollers 5 through the engagement between the two transmission gears 18 to shred the waste paper, and the shredded waste paper is stirred into pulp through the stirring shaft 7. At the same time, the shredded waste paper will first be added with water through the cooperation between the water pipe 17 and the nozzle 6. The waste paper stirred into pulp can be discharged through the discharge port 8. At the same time, the movement of the scraper 9 is controlled by the rotating threaded rod 10 to scrape the inner wall of the bottom side of the processing chamber 1.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
