Description

Technical Field

[0001] The present invention belongs to the technical field of pulverizing mechanisms, and more specifically, relates to a pulverizing mechanism for scraps from paper product processing. Background Art

[0002] The scraps generated during paper processing are usually recycled by shredders. Through this shredding mechanism, paper scraps can be reused after cutting and sorting, reducing paper waste and improving resource utilization efficiency. This equipment is widely used in paper processing, packaging, printing and other industries. However, existing paper shredders have the following disadvantages:

[0003] 1. When using existing paper product shredders, general paper product scraps are in an expanded three-dimensional state. When such paper products are put into the shredder, since the shredder has no squeezing mechanism, the shredder mechanism may be jammed when the paper products come into contact with it.

[0004] 2. When the existing paper product shredder is in use, since the existing shredder does not have a pushing mechanism, a large number of expanded three-dimensional paper products will be stuck in the feed bin and cannot move further when entering the feed bin. At this time, workers need to use tools to push the paper products into the machine, which is time-consuming and labor-intensive and often causes jams.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a paper product processing scrap crushing mechanism is provided, in order to achieve a purpose with greater practical value. Summary of the Invention

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In the present invention, the paper scraps fall onto the surfaces of two dust-proof nets, which are forced to rotate, and then the paper scraps fall into the shredder, where they are cut and shredded by the tool assembly, and finally the particles cut from the paper scraps fall through the discharge pipe. The paper scraps are pushed by the arc-shaped hook on the outside of the first roller, and are squeezed and cut by the second roller, thereby realizing the processing of various paper products, effectively avoiding the problem of paper products being unable to enter the shredder smoothly due to their large size or messy paper products, and solving the problem of paper products being stuck in the feed bin.

[0013] In the present invention, the friction between the rubber pad and the paper product is large, so the pulling force on the paper product can be increased, so that the paper product can be smoothly transported into the feed bin. The distance between each two arc-shaped hooks is large, so the paper product has enough space to move. By using four arc-shaped hooks to pull the paper product into the feed bin, the smoothness of the paper product entering the shredder can be effectively improved. There is no need for workers to push the paper product into the shredder by hand, which greatly improves the speed of the paper product entering.

[0014] In the present invention, when the paper product is pulled by the arc-shaped hook, since different paper products expand to different heights, the arc-shaped hook itself will be subjected to a reaction when pulling the paper product. The arc-shaped hook is forced to drive the sliding bracket to move upward, and the sliding bracket moves upward in the inner slide rail provided in the outer connecting shell. At the same time, the movement of the sliding bracket will drive the multiple second springs to compress and deform. By designing the arc-shaped hook to be able to move obliquely upward, the arc-shaped hook can easily push paper products of different heights or thicknesses, thereby greatly improving the pushing force of the arc-shaped hook on the paper product.

[0015] In the present invention, the expanded paper product is compressed to a certain extent, and a first spring is provided under the lower push rod. Therefore, when the paper product is large and difficult to be compressed, the cutting frame and the lower push rod will be subjected to the downward pressure of the paper product. At the same time, the cutting frame and the lower push rod will rotate downward. At this time, the paper product will fall downward. By using the second roller to squeeze the paper product, the expanded paper product can be compressed, which facilitates the subsequent cutting and crushing of the tool assembly and reduces the risk of the tool assembly being stuck by the expanded paper product.

[0016] In the present invention, a plurality of partitions are provided in the cutting frame, and there is a gap between each partition, and the upper end of each partition is tapered, so the cutter head can cut into the gap between the two partitions, thereby enabling the cutter head to cut the paper product, and each inner slide side wall is provided with a third spring, so when the cutter head encounters a paper product that is difficult to cut, the cutter head is displaced by the reaction force of the paper product, thereby protecting the cutter head, and by arranging a plurality of cutter heads on the surface of the second roller, it is possible to achieve a single-stage cutting and crushing of the paper product, thereby improving the degree of crushing of the paper product by the subsequent tool assembly.

[0017] In the present invention, the cutting frame rotates downward and the two lower push rods drive the lower baffle to rotate downward. The downward rotation of the lower baffle drives the first spring to compress and deform, and the paper product enters the lower section of the feed bin. The paper product contacts the two dust-proof nets, and the two dust-proof nets are rotated under the force. The dust-proof nets and the bracket rotate through the third rotating shaft. The initial state of the two dust-proof nets is a downward oblique angle. Therefore, when the two dust-proof nets are subjected to the gravity of the paper products, they are easy to rotate downward and open. At this time, the paper product enters the shredder and is cut and shredded by the tool assembly. After the paper product enters the shredder, the two dust-proof nets are reset by the torsion spring. At this time, the two dust-proof nets can prevent dust from floating upward, thereby greatly improving the dust reduction effect. BRIEF DESCRIPTION OF THE DRAWINGS

Then the paper scraps fall into the crusher 1, and the paper scraps are cut and crushed by the tool assembly 25. Finally, the particles cut from the paper scraps fall through the discharge pipe 12. The paper scraps are pushed by the arc-shaped hook frame 34 on the outside of the first roller 3, and are extruded and cut by the second roller 4, so that various paper products can be processed. Each external connecting shell 32 is used to push paper products, and at least two inner slides 43 are slidably installed on the surface of the second roller 4. The surface of each inner slide 43 is provided with a cutter head 46, and each cutter head 46 is used to cut paper products.

[0030] The feeding bin 11 is divided into two sections, the upper and lower sections, the first roller 3 and the second roller 4 are both located in the upper section of the feeding bin 11, and the upper section of the feeding bin 11 is in an inclined state, and the lower section of the feeding bin 11 is in a vertical state. Two dust-proof nets 13 are installed inside the lower section of the feeding bin 11, and the side walls of the two dust-proof nets 13 are fixedly installed with brackets 14, and the two brackets 14 are facing relative to each other, and the two brackets 14 are located between the two dust-proof nets 13, and a third rotating shaft 49 is rotatably installed between the two dust-proof nets 13 and the inner wall of the feeding bin 11. Since the arc hook 34 rotates clockwise and the arc hook 34 is arc-shaped, the rotation of the arc hook 34 will drag the paper product into the feeding bin 11, and when the rubber pad 35 at the lower end of the arc hook 34 contacts the paper product, the rubber pad 35 and the paper The friction between the products is large, so the pulling force on the paper products can be increased, so that the paper products can be smoothly transported to the inside of the feed bin 11. The distance between each two arc-shaped hooks 34 is large, and a torsion spring is provided between each dust-proof net 13, the third rotating shaft 49 and the inner wall of the feed bin 11. Two blocks 16 are fixedly installed on the inner walls of the front and rear sides of the feed bin 11, and each block 16 is located above the end of the bracket 14. The ends of the two brackets 14 are tilted downward. The block 16 can limit the upward rotation angle of the dust-proof net 13. When the dust-proof net needs to be cleaned, the user can manually rotate the turntable 15 outside the feed bin 11. The rotation of the turntable 15 can drive the dust-proof net 13 to rotate. Multiple rapid rotations and loosening can achieve the effect of cleaning the dust-proof net 13.

[0031] The cutting frame 2 is rotatably installed at the junction of the upper and lower sections of the feed bin 11, and a second rotating shaft 21 is rotatably installed between the cutting frame 2 and the inner wall of the feed bin 11. The cutting frame 2 is U-shaped, and at least two partitions 23 are fixedly installed inside the cutting frame 2. A lower push rod 22 is fixedly installed below the two U-shaped ends of the cutting frame 2. A lower baffle 17 is rotatably installed on the inner wall of the feed bin 11 below the cutting frame 2, and a first rotating shaft 18 is rotatably installed between the lower baffle 17 and the inner wall of the feed bin 11. The upper surface of the lower baffle 17 is in contact with the two lower push rods 22, so when the paper product is large and difficult to be compressed The cutting frame 2 and the lower push rod 22 will be subjected to the downward pressure of the paper products. At the same time, the cutting frame 2 and the lower push rod 22 will rotate downward. At this time, the paper products will fall downward. By adopting the second roller 4 to squeeze the paper products, the expanded paper products can be compressed. Two first springs 19 are fixedly installed between the lower end of the lower baffle 17 and the right side wall of the feed bin 11. The end of the output shaft of the motor 48 and the drive disk 38 at the end of the first output shaft 31 are fixedly connected. The outer wall of the feed bin 11 is fixedly mounted with a shell 24. The motor 48, the drive disk 38 and the drive belt 39 are all located in the shell 24.

[0032] The side wall of each outer connecting shell 32 is provided with an inner slide rail 33, and the side wall of each arc-shaped hook frame 34 close to the side of the outer connecting shell 32 is fixedly installed with a sliding bracket 36, each sliding bracket 36 is slidably installed in the inner slide rail 33, and a second spring 37 is fixedly installed between the upper end of each sliding bracket 36 and the top of the inner wall of the inner slide rail 33, and a rubber pad 35 is fixedly installed at the lower end of each arc-shaped hook frame 34. The outer side wall of the second roller 4 is provided with at least two inner slide grooves 42, and each inner slide plate 43 is slidably installed in the inner slide groove 42. The upper end of each partition 23 is tapered, so the cutter head 46 can cut into the gap between the two partitions 23, so that the cutter head 46 can cut the paper product, and each inner slide plate 43 side wall is provided with a third spring 44, so When this cutter head 46 encounters a paper product that is difficult to cut again, the cutter head 46 is displaced by the reaction force of the paper product, thereby protecting the cutter head 46. By arranging multiple cutter heads 46 on the surface of the second roller 4, the paper product can be cut and crushed once. A third spring 44 is fixedly installed between the side wall of each inner slide plate 43 located on the inner side of the inner slide groove 42 and the inner wall of the inner slide groove 42. A mounting plate 45 is installed on the side wall of each inner slide plate 43 located on the outer side of the inner slide groove 42. Two screws 47 are installed between each mounting plate 45 and the inner slide plate 43. Each cutter head 46 is fixed to the outer wall of the mounting plate 45. When maintaining the second roller 4, the user can remove the mounting plate 45 and the cutter head 46 by removing the two screws 47 to repair or replace the cutter head 46.

[0033] Working principle:

[0034] In the first step, when crushing the scraps of paper products, start the motor 48, and the motor 48 drives the driving disk 38 at the rear end of the first roller 3 to rotate through the output shaft. The two driving disks 38 are connected and driven by the driving belt 39, so the operation of the motor 48 will drive the first roller 3 and the second roller 4 to rotate. The user puts the scraps of paper products into the feed bin 11, and the four external connecting shells 32 on the surface of the first roller 3 will drive the four arc-shaped hooks 34 to rotate. The four arc-shaped hooks 34 rotate to push the scraps of paper products into the feed bin 11. When the scraps of paper products enter the deep part of the feed bin 11, they will contact the second roller 4, and the second roller 4 will squeeze the scraps of paper products. At the same time, the multiple cutter heads 46 on the surface of the second roller 4 will crush the scraps of paper products. Cutting, the paper scraps cut by the cutter head 46 move to the lower section of the feed bin 11, and the paper scraps fall onto the surface of the two dust-proof nets 13. The two dust-proof nets 13 are rotated under the force, and then the paper scraps fall into the shredder 1. The paper scraps are cut and crushed by the cutter assembly 25, and finally the particles cut from the paper scraps fall through the discharge pipe 12. The paper scraps are pushed by the arc-shaped hook 34 outside the first roller 3, and are squeezed and cut by the second roller 4, so that various paper products can be processed, effectively avoiding the problem that paper products cannot enter the shredder 1 smoothly due to their large size or messy paper products, and solving the problem of paper products being stuck in the feed bin 11.

[0035] In the second step, when the paper products enter the feed bin 11, the first roller 3 rotates to drive the four outer connecting shells 32 to rotate, and the rotation of the four outer connecting shells 32 drives the arc hook 34 to rotate, and the arc hook 34 rotates and contacts the feed bin 11. Since the arc hook 34 rotates clockwise and the arc hook 34 is arc-shaped, the rotation of the arc hook 34 will drag the paper products into the feed bin 11. When the rubber pad 35 at the lower end of the arc hook 34 contacts the paper products, the friction between the rubber pad 35 and the paper products is large, thereby increasing the pulling force on the paper products, thereby smoothly conveying the paper products into the feed bin 11. The distance between each two arc hooks 34 is large, so the paper products have enough space to move. By using four arc hooks 34 to pull the paper products into the feed bin 11, the smoothness of the paper products entering the shredder 1 can be effectively improved, and there is no need for workers to manually push the paper products into the shredder 1, which greatly increases the speed of the paper products entering.

[0036] When the arc-shaped hook 34 pulls the paper product, since different paper products expand to different heights, the arc-shaped hook 34 itself will be subjected to a reaction when pulling the paper product. The arc-shaped hook 34 is forced to drive the sliding bracket 36 to move upward, and the sliding bracket 36 moves upward within the inner slide rail 33 provided in the outer connecting shell 32. At the same time, the movement of the sliding bracket 36 will drive the multiple second springs 37 to be compressed and deformed. By designing the arc-shaped hook 34 to be able to move obliquely upward, the arc-shaped hook 34 can easily push paper products of different heights or thicknesses, thereby greatly improving the pushing force of the arc-shaped hook 34 on the paper products.

[0037] In the third step, when the paper product is pushed to the bottom of the second roller 4 by the arc-shaped hook frame 34 and the paper product is above the cutting frame 2, the second roller 4 continuously rolls to exert downward pressure on the paper product, causing the expanded paper product to be compressed to a certain extent. A first spring 19 is provided under the lower push rod 22. Therefore, when the paper product is large and difficult to be compressed, the cutting frame 2 and the lower push rod 22 will be subjected to the downward pressure of the paper product. At the same time, the cutting frame 2 and the lower push rod 22 will rotate downward, and the paper product will fall downward. By using the second roller 4 to squeeze the paper product, the expanded paper product can be compressed, which facilitates the subsequent cutting and crushing of the cutter assembly 25 and reduces the risk of the cutter assembly 25 being stuck by the expanded paper product.

[0038] When the second roller 4 applies downward pressure to the paper product, the rotation of the second roller 4 drives the multiple inner slides 43 to rotate, and the rotation of the multiple inner slides 43 drives the multiple cutter heads 46 to rotate. The rotation of the multiple cutter heads 46 cuts the paper product, and a plurality of partitions 23 are provided in the cutting frame 2, and there is a gap between each partition 23. The upper end of each partition 23 is tapered, so the cutter head 46 can cut into the gap between two partitions 23, so that the cutter head 46 can cut the paper product. A third spring 44 is provided on the side wall of each inner slide 43. Therefore, when the cutter head 46 encounters a paper product that is difficult to cut, the cutter head 46 is displaced by the reaction force of the paper product, thereby protecting the cutter head 46. By arranging multiple cutter heads 46 on the surface of the second roller 4, the paper product can be cut and crushed once, thereby improving the degree of crushing of the paper product by the subsequent tool assembly 25.

[0039] The downward movement of the paper product drives the cutting frame 2 to rotate downward. The downward rotation of the cutting frame 2 drives the lower baffle 17 to rotate downward through the two lower push rods 22. The downward rotation of the lower baffle 17 drives the first spring 19 to compress and deform, and the paper product enters the lower section of the feed bin 11. The paper product contacts the two dust-proof nets 13. The two dust-proof nets 13 are rotated under the force, and the dust-proof nets 13 and the bracket 14 rotate through the third rotating shaft 49. The initial state of the two dust-proof nets 13 is a downward oblique angle. Therefore, when the two dust-proof nets 13 are subjected to the gravity of the paper product, they can easily rotate downward and open. At this time, the paper product enters the shredder 1 and is cut and shredded by the tool assembly 25. After the paper product enters the shredder 1, the two dust-proof nets 13 are reset by the torsion spring. At this time, the two dust-proof nets 13 can prevent dust from floating upward, thereby greatly improving the dust reduction effect.
