Technical Field

[0001] This utility model relates to the field of waste paper recycling technology, specifically a crushing device for waste paper recycling and processing. Background Technology

[0002] In the waste paper recycling process, the shredding device is one of the key pieces of equipment, used to break waste paper into shreds for subsequent reprocessing or transportation. Existing waste paper shredding devices typically include a shredding box and shredding rollers, which shred the waste paper through rotation. However, the discharge port of the waste paper shredding device is equipped with a collection box, and the shredded paper in the collection box still needs to be packaged in bags, which increases the difficulty of cleaning up the shredded paper and is time-consuming and labor-intensive. Therefore, this application proposes a shredding device for waste paper recycling to solve the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1-4As shown, this utility model provides a technical solution: a crushing device for waste paper recycling, including a crushing box 1. The top side of the crushing box 1 has an outwardly expanding opening for easy loading of waste paper. The bottom end of the crushing box 1 is connected to a screening box 2, and one side of the screening box 2 is connected to an inclined discharge box 3. Two crushing rollers 4 are provided inside the crushing box 1, and the two crushing rollers 4 are driven by a drive structure 5. The drive structure 5 includes two meshing gears and a drive motor. The two gears are respectively mounted on the drive shafts of the two crushing rollers 4. The drive motor is mounted on a protective housing and is connected to one of the drive shafts of the two crushing rollers 4. When the motor of the drive structure 5 is started, the meshing of the two gears drives the two crushing rollers 4 to rotate in opposite directions, crushing the waste paper to be processed. Waste paper is fed into the crushing chamber 1, where two crushing rollers 4 crush it by squeezing. The crushing rollers 4 are equipped with crushing teeth to break the waste paper into shredded paper. Multiple parallel dispersing rods 6 are installed on the bottom side of the crushing chamber 1, with a spacing greater than 3cm between them. An inclined screening plate 7 is installed inside the screening chamber 2. The discharge box 3 corresponds to the bottom of the screening plate 7. A collection box 8 is installed on the bottom side of the screening chamber 2, and an assembly opening is provided on one side of the screening chamber 2 for placing and removing the collection box 8. A quick-release plate is located on the upper part of the side of the screening chamber 2 with the assembly opening, facilitating regular cleaning of the screening plate 7. The crushed shredded paper is dispersed by the dispersing rods 6 as it falls, preventing accumulation and blockage. The shredded paper falls into the inclined screening chamber 2. On plate 7, shredded paper slides into discharge box 3 and falls directly into the packaging bag. Magazine particles mixed in with the shredded paper pass through the sieve holes on the screening plate 7 and fall into the collection box 8 at the bottom. The collection box 8 can be removed through the assembly port for secondary processing. A positioning groove 9 is formed on the outer wall of discharge box 3, and clamping plates 10 are correspondingly installed on the upper and lower sides of the positioning groove 9. The two clamping plates 10 are connected to discharge box 3 via a torsion spring structure 11, clamping and fixing the opening of the packaging bag within the positioning groove 9. After the opening of the packaging bag is clamped and fixed within the positioning groove 9, its bottom end contacts the ground. The torsion spring structure 11 includes a positioning sleeve, a torsion spring, and a positioning shaft. The positioning sleeve and torsion spring are both sleeved on the positioning shaft, which is connected to discharge box 3. The positioning sleeve connects to the clamping plate 10. A torsion spring connects the positioning sleeve and the positioning shaft on both sides, used to apply force to the clamping plate 10 to fit it into the positioning groove 9. The side of the clamping plate 10 that contacts the positioning groove 9 can also be provided with teeth to increase friction with the packing bag. Each of the two clamping plates 10 is connected to a linkage rod 12 on one side, and the outer ends of the two linkage rods 12 are bent inwards. A lever 13 is provided at the bent outer end of the two linkage rods 12, and the upper and lower ends of the lever 13 are provided with collars. The two collars are respectively fitted onto the bent outer ends of the two linkage rods 12. The clamping plate 10 is opened and closed by the linkage rod 12 and the lever 13. Users can easily install or replace the packing bag by simply levering the lever. The operation is intuitive and labor-saving, suitable for frequent operation scenarios.Pushing the lever 13 on the discharge box 3 outward causes the upper and lower ends of the lever 13 to press the curved part of the outer end of the linkage rod 12 outward. This causes the upper and lower clamping plates 10 to open via the linkage rod 12, embedding the edge of the bag opening into the positioning groove 9. Releasing the lever 13 causes the clamping plates 10 to automatically clamp the bag opening under the action of the torsion spring structure 11, ensuring that the bag is firmly fixed and its bottom is in contact with the ground.

[0023] The operational steps for this application are as follows:

[0024] Push the lever 13 on the discharge box 3 outward. The upper and lower ends of the lever 13 are equipped with collars that will press the curved part of the outer end of the linkage rod 12 outward. This will cause the clamping plates 10 on the upper and lower sides to open through the linkage rod 12, so that the edge of the bag opening is embedded into the positioning groove 9. Release the lever 13, and the clamping plate 10 will automatically clamp the bag opening under the action of the torsion spring structure 11, ensuring that the bag is firmly fixed and the bottom is in contact with the ground.

[0025] The motor of the drive structure 5 is started, and the meshing of two gears drives the two crushing rollers 4 to rotate in opposite directions. The waste paper to be processed is put into the crushing box 1. The two crushing rollers 4 squeeze and crush the waste paper, and the waste paper crushing rollers 4 are equipped with crushing teeth to crush the waste paper into paper scraps.

[0026] When the shredded paper falls, it is dispersed by the dispersing rod 6 to prevent accumulation and blockage. The shredded paper falls onto the inclined screening plate 7 in the screening box 2 and slides into the discharge box 3, directly into the packing bag. The magazine particles mixed in with the shredded paper will fall into the collection box 8 at the bottom through the screen holes on the screening plate 7. The collection box 8 can be removed through the assembly port for secondary processing later.

[0027] Once the packing bag is full, move the lever 13 to release the clamping plate 10 and remove the full packing bag.

[0028] By repeatedly installing new baling bags, the waste paper shredding operation can continue.
