Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of paper recycling equipment, and in particular to a pulper for recycling damaged paper. Background Technology
[0002] A pulper is a device used in the wet nonwoven and papermaking industries to break down, fluidize, and disperse pulp boards, waste paper, and other materials generated during the production process, transforming them into fibrous pulp. The main function of a pulper is to mechanically and chemically process raw materials such as waste paper into fibers to facilitate subsequent papermaking processes.
[0003] When recycling waste paper, it needs to be crushed. The crushed paper is soaked and dissolved to facilitate secondary processing. However, after the paper is crushed, the paper is of different sizes, and large pieces are not conducive to subsequent processing. To solve the above problems, a pulper for waste paper recycling is needed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where pulverized paper varies in size, with larger pieces being unsuitable for subsequent processing. This invention proposes a pulper for recycling waste paper.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A pulper for waste paper recycling includes a mixing drum, a shredder box fixedly connected to the upper surface of the mixing drum, a feeding cylinder fixedly connected to the inner wall of the shredder box, an electric telescopic rod fixedly connected to the surface of the mixing drum, the output end of the electric telescopic rod penetrating the inner wall of the feeding cylinder and fixedly connected to a support plate, a sleeve fixedly connected to the upper surface of the support plate, a buffer column slidably connected to the inner wall of the sleeve, a connecting plate rotatably connected to the inner wall of the buffer column, a force-bearing plate fixedly connected to the upper surface of the connecting plate, a sensor fixedly connected to the inner wall of the feeding cylinder, the sensor being installed below the force-bearing plate, and a screening and cutting mechanism provided on the surface of the feeding cylinder.
[0007] Preferably, the screening and cutting mechanism includes a feed hole and a discharge hole on the surface of the feed cylinder, and an inclined plate is fixedly connected to the inner wall of the shredded paper box, with multiple discharge holes on the surface of the inclined plate.
[0008] Furthermore, the inner wall of the shredder is rotatably connected to a linkage shaft, and multiple shredder blades are fixedly connected to the surface of the linkage shaft.
[0009] Preferably, a first spring is fixedly connected to the inner bottom wall of the sleeve, the top end of the first spring is fixedly connected to the lower surface of the buffer column, a second spring is fixedly connected to the surface of the support plate, the top end of the second spring is fixedly connected to the lower surface of the force plate, and a top rod is fixedly connected to the inner bottom wall of the feed cylinder.
[0010] Furthermore, a motor is fixedly connected to the surface of the stirring drum, the output end of the motor passes through the inner wall of the stirring drum and is fixedly connected to an agitator shaft, a drive wheel is fixedly connected to the surface of the agitator shaft, a driven wheel is fixedly connected to the surface of the linkage shaft, and the same belt is fitted onto the surfaces of the drive wheel and the driven wheel.
[0011] Preferably, a controller is fixedly connected to the surface of the mixing drum, and a pair of baffles are fixedly connected to the inner wall of the shredder.
[0012] The beneficial effects of this utility model are as follows:
[0013] The shredded paper falls into the mixing drum through multiple discharge holes for agitation. Larger pieces of paper slide down to the pressure plate in the feed hole under the gravity of the inclined plate and accumulate. The pressure plate then descends under gravity and contacts the surface of the sensor. The output end of the electric telescopic rod drives the pressure plate to rise, and the upper surface of the pressure plate contacts the bottom end of the top rod. At this time, the pressure plate rotates and tilts under the force, discharging the shredded paper on the pressure plate through the discharge hole again. It is then shredded again by multiple shredders. The advantage of this is that the shredded paper is of uniform size, which facilitates subsequent processing operations. Attached Figure Description

A sensor 25 is fixedly connected to the inner wall of the feeding cylinder 8. The sensor 25 is installed below the force-bearing plate 17. A screening and cutting mechanism is provided on the surface of the feeding cylinder 8.
[0021] By setting up a shredder 7, the rotation of the linkage shaft 11 is kept stable, preventing paper from flying out during the shredding process. By setting up an electric telescopic rod 9, the output end of which drives the support plate 19 to change its height. By setting up a force plate 17, the shredded paper is stored. By setting up a sleeve 22, the movement of the buffer column 21 is protected. By setting up a sensor 25, when the sensor 25 is subjected to contact pressure from the force plate 17, the electric telescopic rod 9 is activated by PLC control. By setting up a screening and cutting mechanism, the shredded paper pieces are cut multiple times so that larger pieces of paper can fall into the mixing drum 1 through the discharge hole 14.
[0022] In this utility model, reference Figure 2 and Figure 3 The screening and cutting mechanism includes a feed hole 16 and a discharge hole 15 on the surface of the feed cylinder 8. An inclined plate 13 is fixedly connected to the inner wall of the shredder box 7. Multiple discharge holes 14 are opened on the surface of the inclined plate 13.
[0023] By setting the inclined plate 13, under the action of gravity, paper pieces that do not pass through the discharge hole 14 can be fed into the feed hole 16 and piled up above the force plate 17. By setting the discharge hole 14, smaller paper pieces can be discharged.
[0024] In this utility model, reference Figure 2 The inner wall of the shredder 7 is rotatably connected to a linkage shaft 11, and multiple shredder blades 12 are fixedly connected to the surface of the linkage shaft 11.
[0025] By setting multiple shredders 12, the paper pieces placed in the shredder box 7 are shredded.
[0026] In this utility model, reference Figure 3 and Figure 4 A first spring 23 is fixedly connected to the inner bottom wall of the sleeve 22. The top end of the first spring 23 is fixedly connected to the lower surface of the buffer column 21. A second spring 24 is fixedly connected to the surface of the support plate 19. The top end of the second spring 24 is fixedly connected to the lower surface of the force plate 17. A top rod 18 is fixedly connected to the inner bottom wall of the feeding cylinder 8.
[0027] By setting the first spring 23, the buffer column 21 is driven to perform buffering and shock absorption. By setting the second spring 24, when the force plate 17 is subjected to the pushing pressure from the top rod 18, the force plate 17 and the connecting plate 20 are tilted as a whole, and the cardboard on the force plate 17 is discharged through the feeding hole 15 for multiple crushing and cutting.
[0028] In this utility model, reference Figure 1 and Figure 2 A motor 10 is fixedly connected to the surface of the mixing drum 1.

[0029] By setting a motor 10, its output end drives the stirring shaft 3 to rotate. By setting the stirring shaft 3, the liquid inside the stirring drum 1 is stirred, so that the shredded paper and the liquid are mixed more evenly. By setting a drive wheel 4, the drive wheel 4 drives the driven wheel 5 to rotate through the belt 6, which in turn drives the linkage shaft 11 to rotate.

[0032] Working principle: In use, waste paper is placed into the shredder 7, and the motor 10 is started. The output of the motor 10 drives the agitator 3 to rotate. The agitator 3 drives the belt 6 to rotate through the drive wheel 4. The belt 6 drives the linkage shaft 11 to rotate through the driven wheel 5. The linkage shaft 11 drives multiple shredders 12 to rotate, cutting and shredding the waste paper. The shredded waste paper falls into the mixing drum 1 through multiple discharge holes 14 for mixing. Large pieces of shredded paper slide down to the force plate 17 in the feed hole 16 under the gravity of the inclined plate 13 and accumulate. The force plate 17 is lowered by gravity. After the paper descends and comes into contact with the surface of the sensor 25, the electric telescopic rod 9 is activated by the PLC control. The output end of the electric telescopic rod 9 drives the force plate 17 to rise. After the upper surface of the force plate 17 contacts the bottom end of the top rod 18, the force plate 17 rotates and tilts under the force, and the shredded paper on the force plate 17 is discharged again through the discharge hole 15. After being crushed again by multiple crushing blades 12, it is made smaller and discharged through multiple discharge holes 14. Through the above structure, the waste paper is crushed multiple times to ensure that it can fall into the mixing drum 1 through the discharge hole 14 for mixing and processing.
