The pressing assembly includes a guide seat, a guide box, a compression box, a hydraulic cylinder, a pressure plate, and crushing components. During recycling, the waste paper crushed by the crushing components falls onto the guide seat and then into the compression box. The hydraulic cylinder then activates, pushing the pressure plate to press the shredded waste paper, compressing the finely shredded and irregularly shaped waste paper to make its volume more compact and reasonable. This allows for further centralized processing of the crushed scraps or waste paper during waste paper recycling in paper production, facilitating centralized collection and processing.

[0004] However, the above solution has the following problems when implementing the relevant technology: it cannot perform magnetic separation of waste paper. When cutting the printing paper, the debris or other magnetic metal fragments generated by the wear of the cutting blade may be mixed into the cut waste paper. If not removed, it may damage the subsequent processing equipment. Utility Model Content

[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0032] Example 1

[0033] Please see Figure 1 - Figure 6 A waste paper recycling device for printed paper trimming includes a recycling bin 1, and a crushing component 2 is installed inside the recycling bin 1;

[0034] Both sides of the recycling bin 1 are provided with flow guiding components 3, and both sides of the recycling bin 1 are provided with compression boxes 4, and the other end of the flow guiding component 3 is connected to the compression box 4.

[0035] A compression assembly 5 is provided on the top of the compression chamber 4, and the output end of the compression assembly 5 extends to the inside of the compression chamber 4.

[0036] The recycling bin 1 is equipped with a flipping component 7, on which a first U-shaped shell 8 is fixedly installed, and an electromagnet 9 is fixedly installed on the inner bottom wall of the first U-shaped shell 8.

[0037] This utility model provides a waste paper recycling device for printed paper trimming. In use, waste paper is put into the recycling bin 1 through the feed port. Then, the waste paper is shredded by the crushing component 2. The shredded waste paper falls naturally into the first U-shaped shell 8. Then, the first U-shaped shell 8 is rotated back and forth by the flipping component 7. When the waste paper fragments on the first U-shaped shell 8 enter the compression box 4 from the guide component 3 for compression, under the action of the electromagnet 9, metal fragments or debris mixed in with the waste paper can be adsorbed and removed. This ensures that the recycled waste paper does not contain metal impurities and prevents damage to subsequent processing equipment. Then, the waste paper in the compression box 4 is compressed by the compression component 5, so that the shredded waste paper is more tightly bound and the volume is reduced, making it easier to collect and process.

[0038] Furthermore, the flipping assembly 7 includes a rotating rod 71 rotatably mounted on one side of the inner wall of the recycling bin 1. Two fixing brackets 72 are fixedly mounted on the outer wall of the rotating rod 71, and the first U-shaped shell 8 is fixedly mounted on the fixing bracket 72. A first motor 73 is fixedly mounted on the rear side of the recycling bin 1 through a motor bracket, and the output end of the first motor 73 is fixedly connected to the rotating rod 71.

[0039] Specifically, the first motor 73 drives the rotating rod 71 to rotate, and then the rotating rod 71, under the action of the fixed frame 72, drives the first U-shaped shell 8 to flip back and forth, so that the waste paper scraps on the first U-shaped shell 8 can enter the compression box 4 through the guide assembly 3 for compression.

[0040] Furthermore, the crushing assembly 2 includes two crushing rollers 21 symmetrically arranged inside the recycling box 1, and both ends of the crushing rollers 21 are rotatably connected to the recycling box 1.

[0041] A gear 22 is fixedly installed at one end of each of the two crushing rollers 21, and the two gears 22 are meshed together.

[0042] Mounting brackets 23 are fixedly installed on both sides of the recycling bin 1. A second motor 24 is fixedly installed on one of the mounting brackets 23, and the output end of the second motor 24 is fixedly connected to one of the crushing rollers 21.

[0043] Specifically, the second motor 24 drives the crushing roller 21 connected to its output end to rotate. Then, the rotating crushing roller 21 drives another gear 22 meshing with it through the gear 22 at one end, so that the other crushing roller 21 can also rotate synchronously. This facilitates the crushing of waste paper entering the recycling bin 1, reduces the volume of waste paper during transportation and storage, and enables waste paper to be recycled more quickly.

[0044] Furthermore, the flow guiding component 3 includes a material guiding shell 31 fixedly installed on one side of the recycling box 1, and the other end of the material guiding shell 31 is fixedly connected to the compression box 4. A first conveying port 32 is opened on one side of the compression box 4, and the first conveying port 32 is connected to the material guiding shell 31. A second conveying port 33 is opened on both sides of the recycling box 1, and the second conveying port 33 is connected to the material guiding shell 31.

[0045] Specifically, the shredded waste paper on the first U-shaped shell 8 can enter the compression box 4 for compression processing through the guide shell 31, the first conveying port 32 and the second conveying port 33.

[0046] Furthermore, a second U-shaped shell 10 is provided inside the material guide shell 31, and the second U-shaped shell 10 is fixedly installed on the inner bottom wall of the material guide shell 31.

[0047] Specifically, the second U-shaped shell 10 ensures that the waste paper on the first U-shaped shell 8 can stably enter the guide shell 31, and prevents the waste paper from being unable to enter the compression box 4 from the guide shell 31 due to the gap between the first U-shaped shell 8 and the guide shell 31 when the first U-shaped shell 8 is flipped.

[0048] Furthermore, the compression assembly 5 includes two hydraulic cylinders 51 fixedly mounted on the top of the compression chamber 4, and the output ends of the two hydraulic cylinders 51 extend into the interior of the compression chamber 4 and are jointly fixedly mounted with a pressure plate 52.

[0049] Specifically, the hydraulic cylinder 51 drives the pressure plate 52 to descend, thereby enabling the pressure plate 52 to compress the waste paper scraps in the compression box 4, which in turn allows the shredded waste paper to adhere more tightly and reduces its volume, making it easier to collect and process.

[0050] Example 2

[0051] Based on Embodiment 1, in this embodiment: a pushing component 6 is provided inside the compression box 4. The pushing component 6 includes a rectangular plate 61 fixedly installed at the bottom of the compression box 4. Two electric telescopic rods 62 are fixedly installed on one side of the rectangular plate 61. A U-shaped plate 63 is fixedly installed at the other end of the two electric telescopic rods 62. Two strip grooves 64 are opened at the bottom of the compression box 4. An L-shaped plate 65 is provided inside the compression box 4. Both ends of the U-shaped plate 63 pass through the two strip grooves 64 and are fixedly connected to the L-shaped plate 65.

[0052] The technical solution provided in this embodiment is as follows: the U-shaped plate 63 is pushed by the extended electric telescopic rod 62, so that when the U-shaped plate 63 drives the L-shaped plate 65 to extend out of the compression box 4, the L-shaped plate 65 can move the compressed waste paper on it out of the compression box 4, thereby facilitating manual unloading, reducing unloading time, and also reducing the possibility of waste paper scattering when the compressed waste paper is taken out of the compression box 4.

[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
