Description

Technical Field

[0001] This invention belongs to the field of papermaking equipment technology, and in particular relates to a paper recycling crushing device and its usage method. Background Technology

[0002] Paper, made from plant fibers, is a sheet of paper that can be folded at will for writing. It serves as a medium for writing and printing, and can also be used for packaging, hygiene, and other purposes, such as printing paper, carbon paper, toilet paper, and facial tissue. The invention of paper, with its irregularly cross-arranged fibers, originated in China. In the paper production process, the raw materials used for papermaking are usually crushed first. Some papermaking also uses recycled papermaking waste for crushing.

[0003] For products requiring high-quality paper, high-quality recycled paper is used for shredding and pulping. For products with moderate paper quality requirements, recycled materials containing waste paper tangled with other debris are shredded, screened, and then pulped. The tangled nature of recycled materials containing waste paper and other debris affects shredding efficiency when fed into the shredder. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a paper recycling shredding device and its usage method, which achieves the effects of reducing shredding time and facilitating the screening of shredded materials.

[0005] In view of this, the present invention provides a paper recycling shredding device, including a shredding box, the shredding box including an inlet and an outlet, and the shredding device further including:

[0006] Two crushing rollers are provided in total;

[0007] A drive source, which is connected to the crushing roller to drive the crushing roller to rotate circumferentially;

[0008] A striking component for striking material entering from the feed inlet.

[0009] In this technical solution, the pre-impact can prevent materials from piling up and tangling together, which would prevent them from being crushed in time. This reduces the crushing time, allowing the materials to be crushed to a size that can fall between the two crushing rollers without getting tangled with other debris. In addition, timely dispersal can also reduce the adhesion and overlap of crushed materials, making it easier to screen the crushed materials.

[0010] Furthermore, the striking component includes:

[0011] The crushing box inlet is provided with two inclined guide plates that are arranged opposite each other. The guide plates are provided with sliding holes. The striking shaft passes through the sliding holes and is slidably mounted on the guide plates. The striking shafts on the two guide plates are in a figure-eight shape.

[0012] A drive assembly for driving the striking axis to move along its own axial direction.

[0013] Furthermore, the driving component includes:

[0014] Mounting base, the mounting base is fixedly installed on the outer wall of the crushing box, and a fixing shaft is fixedly installed on the mounting base;

[0015] A cam, which is fixedly sleeved on the end of the crushing roller;

[0016] The rotating rod includes two first and second links that are obtusely angled to each other and fixedly linked. The connection between the first and second links is rotated and linked with a fixed shaft. The end of the first link away from the second link abuts against the outer periphery of the cam. A connecting plate is fixedly connected to the end of the striking shaft located outside the crushing chamber. The end of the second link away from the first link abuts against the side of the connecting plate away from the striking shaft.

[0017] In this technical solution, the crushing roller rotates circumferentially under the action of the drive source, which drives the cam to rotate circumferentially. When the cam cam convex rotates to face the first connecting rod, it will squeeze the first connecting rod and cause the rotating rod to rotate. This will cause the second connecting rod to squeeze the connecting plate, thereby causing the connecting plate to move obliquely upward along its own axis towards the crushing box, striking the material entering from the feed port. The power source of the striking component comes from the rotation of the crushing roller, which can improve the crushing efficiency without adding additional power.

[0018] Furthermore, a return spring is sleeved on the striking shaft. The return spring is located between the guide plate and the connecting plate, and the return spring always has the tendency to push the connecting plate toward the second link.

[0019] In this technical solution, when the cam cam convex part rotates away from the first connecting rod, the return spring force can squeeze the connecting plate to make the striking shaft slide and return to its original position. At the same time, the connecting plate pushes the second connecting rod to make the rotating rod rotate in the opposite direction, so that the first connecting rod abuts against the non-cam cam part.

[0020] Furthermore, a limiting structure is provided on the striking shaft to prevent the striking shaft from sliding out of the guide plate.

[0021] Furthermore, the limiting structure includes a limiting plate, which is disposed on the impact shaft and located in the inner cavity of the crushing chamber, with the outer edge of the limiting plate extending beyond the wall of the sliding hole.

[0022] Furthermore, the striking assembly also includes an anti-snag component, which is used to prevent material from snagging on the end of the striking shaft.

[0023] Furthermore, the anti-snag component includes an anti-snag plate, which is fixedly installed inside the crushing chamber. The anti-snag plate is parallel to the guide plate, and the anti-snag plate has anti-snag holes that match the impact shaft and allow the impact shaft to pass through. The distance from the anti-snag plate to the guide plate is equal to the distance from the limiting plate to the end of the impact shaft located inside the crushing chamber.

[0024] In this technical solution, when the striking shaft slides out to strike the material, some paper strips and other debris will get caught on the striking end of the striking shaft. When the striking shaft slides back to its original position, it will move relative to the fixed anti-snagging plate. The anti-snagging plate can prevent the paper strips and other debris from continuing to move with the striking shaft, causing them to fall off the striking end of the striking shaft, thus ensuring the cleanliness of the striking shaft and the striking force.

[0025] Furthermore, multiple striking shafts are slidably arranged on the guide plate along the length of the crushing roller, and all the striking shafts on one side of the guide plate are fixedly connected to a connecting plate.

[0026] Furthermore, the method of using the pulverizing device includes the following steps:

[0027] S1: Feeding: Input the material into the feed inlet of the crushing box;

[0028] S2: Crushing, two crushing rollers rotate to crush the material, while the striking shaft of the striking component reciprocates to strike the material above the crushing rollers.

[0029] S3: Discharge. The crushed material is discharged from the discharge port of the crushing box.

[0030] The beneficial effects of this invention are:

[0031] 1. Pre-beating can prevent materials from piling up and tangling together, which would prevent them from being crushed in time. It can reduce the crushing time and allow the material to be crushed to a size that can fall between the two crushing rollers without getting tangled with other debris. In addition, timely breaking up can also reduce the adhesion and overlap of crushed materials, making it easier to screen the crushed materials.

[0032] 2. Under the action of the drive source, the crushing roller rotates circumferentially, driving the cam to rotate circumferentially. When the cam cam convex rotates to face the first connecting rod, it will squeeze the first connecting rod, causing the rotating rod to rotate. This will cause the second connecting rod to squeeze the connecting plate, thereby causing the connecting plate to move obliquely upward along its own axis towards the crushing box, striking the material entering from the feed port. The power source of the striking component comes from the rotation of the crushing roller, which can improve the crushing efficiency without adding additional power.

[0033] 3. When the cam cam cam rotates away from the first connecting rod, the return spring force can squeeze the connecting plate to make the striking shaft slide and return to its original position. At the same time, the connecting plate pushes the second connecting rod to make the rotating rod rotate in the opposite direction, so that the first connecting rod abuts against the non-cam ...

[0034] 4. When the striking shaft slides out to strike the material, some paper strips and other debris may get caught on the striking end of the striking shaft. When the striking shaft slides back to its original position, it will move relative to the fixed anti-snagging plate. The anti-snagging plate can prevent paper strips and other debris from continuing to move with the striking shaft, causing them to fall off the striking end of the striking shaft, thus ensuring the cleanliness of the striking shaft and the striking force.

[0047] Example 1

[0048] like Figure 1-2 As shown, a paper recycling shredding device includes a shredding box 1, which includes an inlet 2 and an outlet 3. The shredding device also includes shredding rollers 4, a drive source 5, and a striking assembly 6. Two shredding rollers 4 are provided. The drive source 5 is connected to the shredding rollers 4 to drive the shredding rollers 4 to rotate circumferentially. The striking assembly 6 is used to strike the material entering from the inlet 2.

[0049] Pre-beating can prevent materials from piling up and tangling together, which would prevent them from being crushed in time. It can reduce the crushing time and allow the material to be crushed to a size that can fall between the two crushing rollers 4 before falling off without getting tangled with other debris. In addition, timely breaking up can also reduce the adhesion and overlap of crushed materials, making it easier to screen the crushed materials.

[0050] Example 2

[0051] like Figure 2-4 As shown, the striking assembly 6 includes a striking shaft 7 and a driving assembly. The feed inlet 2 of the crushing box 1 is provided with two inclined guide plates 8 arranged opposite each other. The guide plates 8 are provided with sliding holes 9. The striking shaft 7 is slidably mounted on the guide plates 8 through the sliding holes 9. The striking shafts 7 on the two guide plates 8 are arranged in a V-shape. The driving assembly is used to drive the striking shaft 7 to move along its own axis.

[0052] The drive assembly includes a mounting base 10, a cam 12, and a rotating rod 15. The mounting base 10 is fixedly mounted on the outer wall of the crushing chamber 1, and a fixed shaft 11 is fixedly mounted on the mounting base 10. The cam 12 is fixedly sleeved on the end of the crushing roller 4. The rotating rod 15 includes two interlocking first connecting rods 13 and 14 at obtuse angles. The connection between the first connecting rods 13 and 14 rotates and interlocks with the fixed shaft 11. The end of the first connecting rod 13 away from the second connecting rod 14 abuts against the outer periphery of the cam 12. A connecting plate 16 is fixedly connected to the end of the striking shaft 7 located outside the crushing chamber 1. The end of the second connecting rod 14 away from the first connecting rod 13 abuts against the side of the connecting plate 16 away from the striking shaft 7. Multiple striking shafts 7 are slidably mounted on the guide plate 8 along the length of the crushing roller 4. All striking shafts 7 on one side of the guide plate 8 are fixedly connected to a connecting plate 16.

[0053] Under the action of the drive source 5, the crushing roller 4 rotates circumferentially, driving the cam 12 to rotate circumferentially. When the cam 12 convex part rotates to face the first connecting rod 13, it will squeeze the first connecting rod 13, causing the rotating rod 15 to rotate. This will cause the second connecting rod 14 to squeeze the connecting plate 16, thereby causing the connecting plate 16 to move obliquely upward along its own axis towards the crushing box 1 with the striking shaft 7, striking the material entering from the feed port 2. The power source of the striking component 6 comes from the rotation of the crushing roller 4, which can improve the crushing efficiency without adding additional power.

[0054] Example 3

[0055] like Figure 2-4 As shown, a return spring 17 is sleeved on the striking shaft 7. The return spring 17 is located between the guide plate 8 and the connecting plate 16. The return spring 17 always has a tendency to push the connecting plate 16 towards the second connecting rod 14. When the cam 12 convex part rotates away from the first connecting rod 13, the return force of the return spring 17 can squeeze the connecting plate 16 to make the striking shaft 7 slide and return to its original position. At the same time, the connecting plate 16 pushes the second connecting rod 14 to make the rotating rod 15 rotate in the opposite direction, so that the first connecting rod 13 abuts against the non-convex part of the cam 12.

[0056] The striking shaft 7 is provided with a limiting structure to prevent the striking shaft 7 from sliding out of the guide plate 8. The limiting structure includes a limiting plate 18, which is disposed on the striking shaft 7 and located in the inner cavity of the crushing box 1, with the outer edge of the limiting plate 18 extending beyond the wall of the sliding hole 9.

[0057] The striking assembly 6 also includes an anti-snagging assembly to prevent material from snagging on the end of the striking shaft 7. The anti-snagging assembly includes an anti-snagging plate 19, which is fixedly installed inside the crushing chamber 1. The anti-snagging plate 19 is parallel to the guide plate 8. The anti-snagging plate 19 has anti-snagging holes 20 that match the striking shaft 7 and allow it to pass through. The distance from the anti-snagging plate 19 to the guide plate 8 is equal to the distance from the limiting plate 18 to the end of the striking shaft 7 located inside the crushing chamber 1.

[0058] When the striking shaft 7 slides out to strike the material, some paper strips and other debris may get caught on the striking end of the striking shaft 7. When the striking shaft 7 slides back to its original position, it will move relative to the fixed anti-snagging plate 19. The anti-snagging plate 19 can prevent the paper strips and other debris from continuing to move with the striking shaft 7, causing the paper strips and other debris to fall off the striking end of the striking shaft 7, thus ensuring the cleanliness of the striking shaft 7 and the striking force.

[0059] The method of using the pulverizing device includes the following steps:

[0060] S1: Feeding: Feed the material into the feed port 2 of the crushing box 1;

[0061] S2: Crushing, the two crushing rollers 4 rotate to crush the material, and at the same time the striking shaft 7 of the striking component 6 reciprocates to strike the material above the crushing rollers 4.

[0062] S3: Discharge. The crushed material is discharged from the discharge port 3 of the crushing box 1.

[0063] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
