Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figures 1 - 4 , a waste paper recycling and pulping device provided by the present utility model includes a crushing box 1, a pulping box 2, a feeding cylinder 3 and a stirring assembly 4. The crushing box 1 is arranged on one side of the pulping box 2. The top of the crushing box 1 is provided with a feeding hopper 11. Two crushing rollers 12 are rotatably installed inside the crushing box 1. A driving box 15 for driving the rotation of the crushing rollers 12 is arranged on one side of the crushing box 1. The specific structure of the driving box 15 is a well-known technology and will not be described in detail here. A filter screen 13 is arranged below the crushing rollers 12. The filter screen 13 is arranged obliquely. Through the setting of the crushing box 1, shredded paper can be put into the feeding hopper 11. The shredded paper enters the crushing box 1 through the feeding hopper 11. The driving box 15 drives the crushing rollers 12 to rotate, so that the crushing rollers 12 crush the shredded paper. The large pieces of shredded paper after crushing remain on the filter screen 13, and the small pieces of shredded paper fall down after passing through the filter screen 13.

[0032] The feeding cylinder 3 is fixedly installed on one side of the crushing box 1. The feeding cylinder 3 is arranged vertically. A spiral shaft 31 is rotatably installed inside the feeding cylinder 3. A first motor 32 for driving the rotation of the spiral shaft 31 is fixedly installed at the lower end of the feeding cylinder 3. A through hole 33 is opened between the feeding cylinder 3 and the crushing box 1. The through hole 33 is located above the lower end of the filter screen 13. The upper end of the feeding cylinder 3 is fixedly connected with a feeding pipe 34 extending to the feeding hopper 11. Through the setting of the feeding cylinder 3, during the crushing process, the first motor 32 can be started to drive the spiral shaft 31 to rotate, so that the large pieces of shredded paper on the filter screen 13 enter the feeding cylinder 3 through the through hole 33. The spiral shaft 31 conveys the shredded paper upward, so that the large pieces of shredded paper are sent back to the feeding hopper 11 through the feeding pipe 34 for secondary crushing, and manual feeding operation is not required, which can save labor.

[0033] An inlet opening 14 is opened between the bottom of the crushing box 1 and the pulping box 2. A guiding block 16 is fixedly connected to the inner bottom wall of the crushing box 1. The top surface of the guiding block 16 is arranged obliquely upward in a direction away from the inlet opening 14. The shredded paper falling on the filter screen 13 slides along the guiding block 16 towards the inlet opening 14 and thus enters the pulping box 2 through the inlet opening 14 for pulping. A discharge pipe 21 is fixedly connected to the bottom of the pulping box 2. A valve is installed on the discharge pipe 21. After the pulping is completed, the valve can be opened to discharge the pulp in the pulping box 2 from the discharge pipe 21.

[0034] The stirring assembly 4 includes a second motor 41 fixedly installed on the top of the pulping tank 2. The output end of the second motor 41 is fixedly connected to a first stirring rod 42. A plurality of first stirring blades 43 are fixedly connected to the surface of the first stirring rod 42. Support plates 44 are fixedly connected to both sides of the first stirring rod 42. A second stirring rod 45 is rotatably installed on the support plates 44. A plurality of second stirring blades 46, which are staggered with the first stirring blades 43, are fixedly connected to the surface of the second stirring rod 45. Through the setting of the stirring assembly 4, during pulping, the second motor 41 can be started to drive the first stirring rod 42 to rotate, so that the first stirring rod 42 drives the first stirring blades 43 to stir. At the same time, the first stirring rod 42 also drives the second stirring rod 45 to rotate around the first stirring rod 42, so that the second stirring rod 45 drives the second stirring blades 46 to move in a circular motion around the first stirring rod 42, expanding the stirring range.

[0035] Furthermore, a sleeve 47 is fixedly connected to the center of the inner top wall of the pulping tank 2. A fixed gear 48 is fixedly installed on the surface of the sleeve 47. The upper end of the second stirring rod 45 is fixedly connected to a rolling gear 49 that meshes with the fixed gear 48. Through the setting of the sleeve 47, the fixed gear 48 and the rolling gear 49, when the second stirring rod 45 rotates around the first stirring rod 42, the second stirring rod 45 will drive the rolling gear 49 to roll along the fixed gear 48, so that the rolling gear 49 drives the second stirring rod 45 to rotate itself, and the second stirring rod 45 drives the second stirring blades 46 to rotate around the second stirring rod 45, making the stirring more delicate and improving the pulping effect.

[0036] Working principle: Shredded paper can be put into the feeding hopper 11. The shredded paper enters the crushing box 1 through the feeding hopper 11. The driving box 15 drives the crushing roller 12 to rotate, so that the crushing roller 12 crushes the shredded paper. The large pieces of shredded paper after crushing remain on the filter screen 13. During the crushing process, the first motor 32 can be started to drive the spiral shaft 31 to rotate, so that the large pieces of shredded paper on the filter screen 13 enter the feeding cylinder 3 through the through holes 33. The spiral shaft 31 conveys the shredded paper upward, so that the large pieces of shredded paper are sent back to the feeding hopper 11 through the feeding pipe 34 for secondary crushing, eliminating the need for manual feeding operation and saving labor. The small pieces of shredded paper fall after passing through the filter screen 13. The shredded paper falling on the filter screen 13 slides along the guiding block 16 towards the feeding port 14, and then enters the pulping tank 2 through the feeding port 14 for pulping. During pulping, the second motor 41 can be started to drive the first stirring rod 42 to rotate, so that the first stirring rod 42 drives the first stirring blades 43 to stir. At the same time, the first stirring rod 42 also drives the second stirring rod 45 to rotate around the first stirring rod 42, so that the second stirring rod 45 drives the second stirring blades 46 to move in a circular motion around the first stirring rod 42, expanding the stirring range. When the second stirring rod 45 rotates around the first stirring rod 42, the second stirring rod 45 will drive the rolling gear 49 to roll along the fixed gear 48, so that the rolling gear 49 drives the second stirring rod 45 to rotate self, so that the second stirring rod 45 drives the second stirring blades 46 to rotate around the second stirring rod 45, making the stirring more delicate and improving the pulping effect.
