[0002] Cardboard boxes are a common packaging material, typically used for transporting and storing goods. They are lightweight, recyclable, and low-cost. During the cardboard box manufacturing process, excess scraps are often generated. These scraps need to be shredded and recycled using waste paper shredding equipment. Existing waste paper shredding equipment uses shredding rollers for this purpose. However, due to the high-speed rotation of the rollers during shredding, paper scraps often fly around, potentially causing injury to personnel and polluting the surrounding environment. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a waste paper shredding device for cardboard box processing, which solves the problem that existing waste paper shredding devices cause paper scraps to fly during the shredding process due to the high-speed rotation of the shredding roller, which not only easily causes injury to personnel, but also pollutes the surrounding environment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a waste paper shredding device for cardboard box processing, comprising a box body, an L-shaped plate fixedly connected to the box body, a motor fixedly connected to the L-shaped plate, a drive gear fixedly connected to the output end of the motor, a driven gear meshing with the drive gear, a first shredding roller fixedly connected to the drive gear, and a second shredding roller fixedly connected to the driven gear. The first and second shredding rollers are rotatably connected inside the box body, and a feed hopper is fixedly connected to the top of the box body, with a cover plate hinged to the top of the feed hopper.

[0005] A connecting plate is fixedly connected to one side of the cover plate, and two limiting grooves are opened on the connecting plate. Four fixing blocks are fixedly connected to one side of the feed hopper. Two fixing blocks are fixedly connected to fixing rods, and two bidirectional lead screws are rotatably connected to the other two fixing blocks. Two moving rods are threadedly connected to the bidirectional lead screws. The moving rods are slidably connected to the fixing rods. Limiting rods are fixedly connected to the moving rods, and the limiting rods are located inside the limiting grooves.

[0006] As a further embodiment of this utility model: a knob is fixedly connected to one end of the bidirectional lead screw, and the knob has several grooves.

[0009] As a further embodiment of this utility model: a second handle is fixedly connected to the top of the cover plate, and both the first crushing roller and the second crushing roller are located at the top of the collection box.

[0010] As a further embodiment of this utility model: the number of limiting rods is two, and the two limiting rods are symmetrically arranged about the middle of the connecting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This waste paper shredding device for cardboard box processing is equipped with a cover plate, a limiting groove, a limiting rod, a bidirectional screw, and a moving rod. In use, first turn the knob to rotate the bidirectional screw. Because the threads on both sides of the bidirectional screw are in opposite directions, when the bidirectional screw rotates, the two moving rods move away from each other. The moving rods drive the limiting rod to move, causing the limiting rod to disengage from the limiting groove, thus releasing the connection plate from the fixed state of the cover plate. At this point, the second handle can be held to open the cover plate and place waste paper into the feed hopper. After the waste paper is placed, close the cover plate and turn the knob in the opposite direction to rotate the bidirectional screw, causing the two moving rods to move closer together. The moving rods drive the limiting rod to move, causing the limiting rod to insert into the limiting groove, thereby fixing the connection plate and the cover plate. By closing and fixing the cover plate, this device can prevent paper scraps from flying during the shredding process, avoiding injury to personnel and preventing pollution of the surrounding environment.

[0013] 2. This waste paper shredding device for cardboard box processing, by setting up a collection box, a screw, and a first handle, with the driving gear and driven gear respectively driving the first shredding roller and the second shredding roller to rotate, thereby shredding the waste paper. The shredded waste paper falls into the collection box for collection. When it is necessary to remove the collection box, loosen the screw to release the collection box from its fixed state, and hold the first handle to remove the collection box, pour out the waste paper inside the collection box, put the collection box back into the box body, and tighten the screw to fix the collection box. This device collects the shredded waste paper through the collection box, which facilitates the subsequent centralized processing of waste paper. Moreover, by fixing the collection box, the stability of the collection box is improved, and the displacement of the collection box is prevented. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-5 As shown, this utility model provides a technical solution: a waste paper shredding device for cardboard box processing, including a box body 1, with screws 4 threadedly connected to both sides of the box body 1, and a collection box 5 provided inside the box body 1. Because of the collection box 5, the collection box 5 can collect the shredded waste paper, thereby facilitating the subsequent centralized processing of waste paper. An L-shaped plate 18 is fixedly connected to the box body 1, and a motor 19 is fixedly connected to the L-shaped plate 18. A drive gear 20 is fixedly connected to the output end of the motor 19, and a driven gear 21 meshes with the drive gear 20. A first shredding roller 7 is fixedly connected to the drive gear 20.

[0022] A second crushing roller 8 is fixedly connected to the driven gear 21. Both the first crushing roller 7 and the second crushing roller 8 are rotatably connected inside the housing 1. A feed hopper 2 is fixedly connected to the top of the housing 1. A cover plate 3 is hinged to the top of the feed hopper 2. A connecting plate 14 is fixedly connected to one side of the cover plate 3. Two limiting grooves 16 are opened on the connecting plate 14. A first handle 6 is fixedly connected to the collection box 5. Because of the first handle 6, the first handle 6 provides a gripping point, making it easy for personnel to hold the first handle 6 to take out the collection box 5, reducing the difficulty of operation. The first handle 6 has an arc surface design.

[0023] Four fixed blocks 9 are fixedly connected to one side of the feed hopper 2. Fixed rods 10 are fixedly connected to two of the fixed blocks 9. Because of the fixed rods 10, when the moving rod 12 moves, the fixed rods 10 limit the moving rod 12, thereby improving the stability of the movement. Two bidirectional lead screws 11 are rotatably connected to the other two fixed blocks 9. A knob 15 is fixedly connected to one end of the bidirectional lead screw 11. Several grooves are opened on the knob 15. Because the knob 15 has several grooves, it can increase friction and make it easier for personnel to turn the knob 15, improving the ease of operation. Two moving rods 12 are threadedly connected to the bidirectional lead screw 11.

[0024] The movable rod 12 is slidably connected to the fixed rod 10. The movable rod 12 is fixedly connected to the limiting rod 13. There are two limiting rods 13. The two limiting rods 13 are symmetrically arranged about the middle of the connecting plate 14. The limiting rods 13 are located inside the limiting groove 16. The top of the cover plate 3 is fixedly connected to the second handle 17. The first crushing roller 7 and the second crushing roller 8 are both located on the top of the collection box 5.

[0025] The working principle of this utility model is as follows:

[0026] In use, first turn the knob 15 to drive the bidirectional lead screw 11 to rotate. Since the threads on both sides of the bidirectional lead screw 11 are opposite, when the bidirectional lead screw 11 rotates, the two moving rods 12 will move away from each other. The moving rods 12 drive the limiting rod 13 to move, so that the limiting rod 13 is disengaged from the limiting groove 16, thereby releasing the fixed state between the connecting plate 14 and the cover plate 3. At this time, you can hold the second handle 17 to open the cover plate 3 and place the waste paper into the feed hopper 2. After the waste paper is placed, close the cover plate 3 and turn the knob 15 in the opposite direction to drive the bidirectional lead screw 11 to rotate, so that the two moving rods 12 move closer to each other. The moving rods 12 drive the limiting rod 13 to move, so that the limiting rod 13 is inserted into the limiting groove 16, thereby fixing the connecting plate 14 and the cover plate 3.

[0027] At this time, the start motor 19 drives the drive gear 20 to rotate. Since the drive gear 20 meshes with the driven gear 21, the drive gear 20 can drive the driven gear 21 to rotate. The drive gear 20 and the driven gear 21 respectively drive the first crushing roller 7 and the second crushing roller 8 to rotate, thereby crushing the waste paper. The crushed waste paper falls into the collection box 5 for collection. When it is necessary to remove the collection box 5, loosen the screw 4 to release the fixed state of the collection box 5, and hold the first handle 6 to remove the collection box 5, pour out the waste paper inside the collection box 5, put the collection box 5 back into the box 1, and tighten the screw 4 to fix the collection box 5.
