Description

Technical Field

[0001] The utility model relates to the technical field of waste paper processing, in particular to a crushing device for waste paper processing. Background Art

[0002] In the papermaking process, processes such as trimming the edges of paper and cutting the paper according to specified specifications will be carried out, and a lot of waste paper will be generated during this process. To improve the material utilization rate, the waste paper needs to be recycled. When recycling waste paper, a crushing device is usually required to crush it. The Chinese authorized utility model patent (publication number: CN221029280U) discloses a waste paper crushing device. This device reduces the situation that when the device is in use and the feeding conveyor conveys waste paper, the paper is easily mixed with iron products, and the iron products enter the interior of the device, which is likely to damage the interior of the device and cause it to malfunction and unable to crush the waste paper normally, thus improving the practicability of the device.

[0003] In the above device, the iron in the waste paper is adsorbed by a magnet. However, as more and more iron is adsorbed on the surface of the magnet, it is necessary to clean it regularly. When the magnet in the prior art is removed and cleaned, the whole device cannot continue to carry out the iron adsorption operation. Therefore, the feeding conveyor needs to be shut down, which will affect the overall efficiency of waste paper crushing. Therefore, a crushing device for waste paper processing is proposed in view of the above situation. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect of affecting the overall working efficiency when cleaning the magnet in the prior art, and to propose a crushing device for waste paper processing.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A crushing device for waste paper processing includes a main body, a feeding conveyor is arranged on the main body, and a cleaning mechanism is arranged on the feeding conveyor.

[0007] The cleaning mechanism includes a support plate rotatably fitted on the feeding conveyor. A pair of assembly grooves are formed on the support plate. A driving shaft is arranged on one side of the support plate. The driving shaft passes through the feeding conveyor and is fixedly connected with a turntable.

[0008] A positioning pin for positioning the turntable is arranged on the turntable. One end of the positioning pin is inserted into the feeding conveyor. A pair of adsorption components are arranged on the support plate.

[0009] Preferably, a through hole is formed through one side plate of the feeding conveyor, and the driving shaft is in clearance fit with the through hole.

[0010] Preferably, a positioning hole is formed on the feeding conveyor, and the positioning pin is inserted into the positioning hole.

[0011] Preferably, a pair of dial blocks are arranged on the surface of the turntable, and jacks for cooperating with the positioning pins are arranged on the pair of dial blocks.

[0012] Preferably, the adsorption assembly includes a magnet arranged in the assembly groove. The adsorption assembly further includes a first side plate and a second side plate arranged on the surface of the support plate. A screw rod is threadedly connected through the second side plate, and one end of the screw rod is connected with a limiting plate, and the bottom of the limiting plate is slidably matched with the surface of the support plate.

[0013] Preferably, one side of the magnet contacts the first side plate, and the other side of the magnet contacts the limiting plate.

[0014] The utility model has the following beneficial effects:

[0015] 1. Through the structural design of the support plate, the turntable, the positioning pins and a pair of adsorption assemblies, the utility model allows the cleaning work of the magnet to be carried out without stopping the machine. When one magnet adsorbs more iron, it can be quickly rotated to the upper part to facilitate the worker to disassemble and clean it. At the same time, the other magnet that does not adsorb iron rotates to the lower part to continue working. The alternating use mode greatly reduces the downtime and improves the continuity and efficiency of the whole waste paper processing process.

[0016] 2. Through the structural design of the turntable and the positioning pins, the utility model can position the rotated support plate, thereby ensuring the stability of the magnet during the iron adsorption work. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Referring to Figures 1-4 , a crushing device for waste paper processing, including a main body 1, an inlet conveyor 2 is arranged on the main body 1, and a cleaning mechanism 3 is arranged on the inlet conveyor 2.

[0024] Furthermore, an outlet conveyor for discharging is also arranged on the main body 1, a component for crushing waste paper is arranged inside the main body 1, and the composition structure of the main body 1 is the same as that in the prior art (publication number: CN221029280U), and will not be elaborated here.

[0025] The cleaning mechanism 3 includes a support plate 4 rotatably fitted on the inlet conveyor 2. A pair of assembly grooves 401 are formed on the support plate 4. A driving shaft 402 is arranged on one side of the support plate 4. After passing through the inlet conveyor 2, the driving shaft 402 is fixedly connected to a turntable 403.

[0026] Specifically, a through hole is formed through a side plate of the inlet conveyor 2, and the driving shaft 402 is in clearance fit with the through hole.

[0027] A positioning pin 404 for positioning the turntable 403 is arranged on the turntable 403. Furthermore, a pair of dial blocks are arranged on the surface of the turntable 403, and jacks for cooperating with the positioning pin 404 are arranged on the pair of dial blocks.

Specifically, as Figure 3 shown, a positioning hole is formed on the inlet conveyor 2, the positioning pin 404 is inserted into the positioning hole, and a pair of adsorption components 5 are arranged on the support plate 4.

[0029] During use, the cleaning work of the magnet 501 is allowed to be carried out without stopping the machine. When a large amount of iron is adsorbed by one magnet 501, first take out the positioning pin 404, then rotate the turntable 403. The rotation of the turntable 403 causes the driving shaft 402 to rotate, and then the support plate 4 rotates 180°. Then insert the positioning pin 404 into the jack on the turntable 403, and at the same time, insert the positioning pin 404 into the positioning hole to achieve positioning. The magnet 501 with a large amount of adsorbed iron can be quickly rotated to the upper part, which is convenient for workers to disassemble and clean. At the same time, another magnet 501 that does not adsorb iron rotates to the lower part to continue working. The alternating use mode greatly reduces the downtime and improves the continuity and efficiency of the entire waste paper processing process.

[0030] In this embodiment, as Figure 2 and Figure 4As shown in the figure, the adsorption component 5 includes a magnet 501 disposed in the assembly groove 401. The adsorption component 5 further includes a first side plate 502 and a second side plate 503 disposed on the surface of the support plate 4. A screw rod 504 is threadedly penetrated and connected to the second side plate 503. One end of the screw rod 504 is connected with a limiting plate 505. The bottom of the limiting plate 505 is slidably matched with the surface of the support plate 4. One side of the magnet 501 contacts the first side plate 502, and the other side of the magnet 501 contacts the limiting plate 505.

[0031] Furthermore, the cooperation of the first side plate 502 and the second side plate 503 is used to fix and limit the magnet 501 inserted in the assembly groove 401, ensuring the stability of the magnet 501 during operation.
