Description

Technical Field

[0001] This utility model relates to the field of waste paper recycling technology, and in particular to a waste paper recycling device for papermaking. Background Technology

[0002] In the papermaking industry, a large amount of waste paper is generated due to operational or equipment problems. To avoid waste, waste paper needs to be recycled. The raw materials for paper are mainly plant fibers such as wood, grass, reeds, and bamboo. Waste paper is also known as "secondary fiber," and its primary use is for fiber recycling to produce recycled paper products. Recycled paper is made from waste paper as raw material, which is crushed, decolorized, pulped, and processed through multiple steps. 80% of its raw materials come from recycled waste paper, thus it is hailed as a low-energy, low-pollution, environmentally friendly paper. After recycling, waste paper is usually crushed before further processing.

[0003] When existing devices shred waste paper, the housing needs sufficient space for the internal shredder blades to rotate, resulting in a certain distance between the blades and the inner wall of the housing. As a result, some waste paper may remain in the dead corners of the blades during shredding, thus reducing the shredding effect. Utility Model Content

[0004] This utility model discloses a waste paper recycling device for papermaking, which aims to solve the technical problem that, because the shell needs to have enough space for the internal shredder to rotate, resulting in a certain distance between the blade and the inner wall of the shell, some waste paper will be trapped in the dead corner of the blade during shredding and cannot be contacted by the shredder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste paper recycling device for papermaking includes a housing, a feed hopper fixedly connected to the upper end of the housing, a base fixedly connected to the lower left side of the housing, and a crushing mechanism provided inside the housing.

[0007] The crushing mechanism includes a motor fixedly connected to the upper end of the housing, a rotating rod fixedly connected to the output end of the motor, crushing blades evenly arranged on the rod wall, a filter screen provided at the lower end of the housing, a rectangular groove opened at the lower end of the rotating rod, a moving block slidably connected inside the rectangular groove, the two sides of the moving block being fixedly connected to the crushing blades at the lower end, a spring fixedly connected to the upper end of the moving block, a round block fixedly connected to the lower end of the rotating rod, a first protrusion fixedly connected to the upper end of the round block, and a second protrusion provided at the lower end of the filter screen.

[0008] Preferably, a rotating block is fixedly connected to the outer side of the movable block, and the rotating block is rotatably connected to the upper end of the filter screen;

[0009] Preferably, the inner walls on both sides of the housing are provided with sliding grooves, and a slider is slidably connected inside the sliding grooves, and the slider is fixedly connected to the filter screen;

[0010] Preferably, the outer edge of the upper end of the filter screen is inclined;

[0011] Preferably, a guide plate is fixedly connected to the lower end of the housing.

[0012] As can be seen from the above, the advantages of the waste paper recycling device for papermaking provided by this utility model are as follows: During operation, the filter screen moves up and down through the first and second protrusions, allowing the waste paper located in the corner to be pushed upwards and thus come into contact with the shredder blade, improving the shredding effect. At the same time, the up and down movement of the filter screen can increase the filtration speed of the filter screen. Attached Figure Description

[0021] Reference Figure 1-4 A waste paper recycling device for papermaking includes a housing 1. A feeding hopper 3 is fixedly connected to the upper end of the housing 1, through which materials are fed into the housing 1. A guide plate 4 is fixedly connected to the lower end of the housing 1, which is used to discharge the crushed paper scraps. A base 5 is fixedly connected to the lower left side of the housing 1, which is used for support. A crushing mechanism is provided inside the housing 1.

[0022] The shredding mechanism includes a motor 2 fixedly connected to the upper end of the housing 1. The motor 2 is a drive device. In the prior art, a rotating rod 12 is fixedly connected to the output end of the motor 2. The motor 2 drives the rotating rod 12 to rotate. Shredding blades 11 are evenly arranged on the rod wall of the rotating rod 12. The rotation of the rotating rod 12 drives the shredding blades 11 to rotate, shredding the waste paper. A filter screen 9 is provided at the lower end of the interior of the housing 1 to filter paper scraps. A rectangular groove 15 is opened at the lower end of the rotating rod 12. A moving block 14 is slidably connected inside the rectangular groove 15. The moving block 14 can... The moving block 14 moves up and down inside the rectangular groove 15. The two sides of the moving block 14 are fixedly connected to the crushing blade 11 at the lower end. When the moving block 14 moves up and down, it drives the crushing blade 11 at the lower end to move. The upper end of the moving block 14 is fixedly connected to a spring 13. The spring 13 has a downward pushing force on the moving block 14. The lower end of the rotating rod 12 is fixedly connected to a round block 6. The rotating rod 12 rotates and drives the round block 6 to rotate. The upper end of the round block 6 is fixedly connected to a first protrusion 7. The rotation of the round block 6 drives the first protrusion 7 to move. The lower end of the filter screen 9 is provided with a second protrusion 8.

[0023] During operation, the material to be crushed is fed into the housing 1 through the feed hopper 3. At this time, the motor 2 starts, causing the rotating rod 12 to rotate. The rotating rod 12 drives the crushing blade 11 to rotate, thereby crushing the waste paper. The paper scraps are then sieved through the filter screen 9 and discharged through the guide plate 4. Simultaneously, the rotation of the rotating rod 12 drives the circular block 6 to rotate, which in turn moves the first protrusion 7. The first protrusion 7 then contacts the second protrusion 8, causing the second protrusion 8 to move upwards. The second protrusion 8 then moves the filter screen 9 upwards. When the filter screen 9 moves upward, it causes the waste paper at the lower end to move upward as well. When the filter screen 9 moves, the moving block 14 at the lower end causes the shredder 11 at the lower end to move upward. This allows the waste paper located at the edge of the filter screen 9 to be pushed upward. The distance between the shredder 11 at the lower end and the filter screen 9 remains unchanged, thus shredding the pushed waste paper. In this way, during operation, the waste paper located in the corner can be pushed upward, so that it can come into contact with the shredder 11, improving the shredding effect. At the same time, the up and down movement of the filter screen 9 can increase the filtration speed of the filter screen 9.

[0024] Reference Figure 4 A rotating block 10 is fixedly connected to the outer side of the movable block 14. The rotating block 10 is rotatably connected to the upper end of the filter screen 9. When the rotating rod 12 drives the movable block 14 to rotate, the rotation of the rotating block 10 and the filter screen 9 avoids friction between the movable block 14 and the filter screen 9, thus preventing component wear.

[0025] Reference Figure 2 and Figure 3 The inner walls on both sides of the housing 1 are provided with sliding grooves 17. A slider 16 is slidably connected inside the sliding groove 17. The slider 16 is fixedly connected to the filter screen 9. The slider 16 moves inside the sliding groove 17, so that the filter screen 9 can move up and down stably.

[0026] Reference Figure 4 The upper outer edge of the filter screen 9 is inclined, so that when it moves upward, it has an inward force to push the waste paper, increasing the contact between the waste paper and the shredder 11 and improving the shredding effect.

[0027] Working principle: During operation, the material to be crushed is fed into the housing 1 through the feed hopper 3. At this time, the motor 2 starts, causing the rotating rod 12 to rotate. The rotating rod 12 drives the crushing blade 11 to rotate, thereby crushing the waste paper. The paper scraps are then sieved through the filter screen 9 and discharged through the guide plate 4. Simultaneously, the rotation of the rotating rod 12 drives the circular block 6 to rotate, which in turn moves the first protrusion 7. The first protrusion 7 then contacts the second protrusion 8, causing the second protrusion 8 to move upwards. The second protrusion 8 then moves the filter screen 9 upwards, filtering the waste paper. When the screen 9 moves upward, it causes the waste paper at the lower end to move upward as well. When the screen 9 moves, the moving block 14 at the lower end causes the shredder 11 at the lower end to move upward. This allows the waste paper located at the edge of the screen 9 to be pushed upward. The distance between the shredder 11 at the lower end and the screen 9 remains unchanged, thus shredding the pushed waste paper. In this way, during operation, the waste paper located in the corner can be pushed upward, allowing it to come into contact with the shredder 11, improving the shredding effect. At the same time, the up and down movement of the screen 9 can increase the filtration speed of the screen 9.
