A regenerated paper crushing device with high-efficiency stirring mechanism

Abstract

This utility model belongs to the field of recycled paper shredding technology, specifically relating to a recycled paper shredding device with a high-efficiency stirring mechanism. It includes a fixed frame with a tank fixedly installed on the inner wall of the frame. Waste paper is fed from a vibrating plate. The recycled paper may contain impurities such as staples and plastic film, which can easily jam the shredding wheels or damage the stirring blades, causing the machine to stop. These impurities are separated by vibration and then attracted by a magnetic roller, while the impurities fall into a collection tank. The separated waste paper then enters the shredder for further shredding and subsequently enters the tank for further processing. This design protects the shredder from hard impacts and entanglement, reducing the failure rate and extending its service life. If the staples separated by vibration fall directly, they may mix into subsequent paper scraps or the bottom of the equipment, forming secondary impurities. The magnetic roller, through reciprocating movement, can cover the entire material feeding area below the vibrating plate, attracting the staples to the roller surface and preventing them from scattering.

Description

Technical Field

[0001] This utility model belongs to the field of recycled paper shredding technology, specifically relating to a recycled paper shredding device with a high-efficiency stirring mechanism. Background Technology

[0002] A recycled paper shredding device with a high-efficiency stirring mechanism is an integrated equipment designed specifically for the pretreatment of recycled paper. Its core function is to crush waste paper (such as waste paper, cardboard boxes, newspapers, etc.) into uniform fine paper scraps through the coordinated operation of shredding and stirring, providing high-quality raw materials for the subsequent pulping process.

[0003] Patent publication number CN217527603U discloses a recycled paper shredding device with a high-efficiency stirring mechanism. The shredding wheel of this utility model is equipped with comb teeth below it. The comb teeth can brush off the recycled paper adhering to the shredding wheel to prevent excessive recycled paper from reducing the shredding efficiency. A stirring rod is designed to further break up and stir the shredded recycled paper. At the same time, a cutting blade is set on the stirring rod to further cut the recycled paper while enhancing the stirring effect.

[0004] However, the current recycled paper shredding devices with efficient mixing mechanisms have the following problems: when metal impurities such as staples enter the shredding wheel, they will directly impact the shredding teeth and wheel shaft, causing the teeth to break and the shaft to wear, which increases downtime and maintenance costs.

[0005] Tough impurities such as plastic film and tape can get tangled on the shredding wheel, causing the motor load to increase continuously. Therefore, we propose a recycled paper shredding device with a high-efficiency stirring mechanism. Utility Model Content

[0006] The purpose of this invention is to provide a recycled paper shredding device with a high-efficiency stirring mechanism, which can solve the problem in related technologies where metal impurities such as staples enter the shredding wheel and directly impact the shredding teeth and wheel shaft, causing the teeth to break and the shaft to wear, resulting in increased downtime and maintenance costs.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A recycled paper shredding device with a high-efficiency stirring mechanism includes a fixed frame, a tank fixedly installed on the inner wall of the fixed frame, a baffle fixedly installed on the top of the tank, a discharge port on the outer wall of the tank, a shredder installed on the inner wall of the baffle, a pretreatment mechanism installed on the front side of the baffle, the pretreatment mechanism including a connecting frame fixedly installed on the front side of the baffle, a vibrating plate slidably installed on the inner wall of the connecting frame, a spring seat between the vibrating plate and the connecting frame, and a fixed end of a vibration motor on the surface of the vibrating plate. Waste paper is input from the vibrating plate, causing the vibration motor to start and generate vibration, which in turn causes the vibrating plate to shake. The shaking of the vibrating plate compresses the spring seat and is then reset by the spring seat, so that the vibrating plate shakes and vibrates simultaneously.

[0009] The number of spring seats is set to four, in pairs, and symmetrical to each other along the vertical central axis of the connecting frame. The number of vibration motors is set to two, and symmetrical to each other along the vertical central axis of the connecting frame.

[0010] The surface of the connecting frame is provided with a reciprocating lead screw, and a sliding button is threaded on the circumferential surface of the reciprocating lead screw. The number of the reciprocating lead screw and the sliding button is set to two, and they are symmetrical to each other along the vertical central axis of the connecting frame.

[0011] The inner wall of the sliding button is fixedly installed with the fixed end of the first servo motor, and the output end of the first servo motor is fixedly installed with a magnetic roller. The sliding button is moved by the rotation of the reciprocating screw, and the movement of the sliding button drives the first servo motor to move. The movement of the first servo motor drives the magnetic roller to move, so that the magnetic roller moves while rotating.

[0012] The inner wall of the connecting frame is provided with a sliding groove, and a collection trough is slidably installed on the surface of the sliding groove.

[0013] The tank is equipped with a stirring mechanism, which includes a fixed end of a servo motor II and a circular rod fixedly mounted on the output end of the servo motor II. A stirring blade is fixedly mounted on the circumferential surface of the circular rod, and the surface of the stirring blade is provided with a cutting surface. There are two stirring blades, which are symmetrical about each other along the vertical central axis of the circular rod. The circular rod is rotated by the output end of the servo motor II, which in turn drives the stirring blade to rotate, so that the stirring blade mixes the waste paper.

[0014] A receiving frame is fixedly installed on the circumferential surface of the round rod, and a rubber plate is fixedly installed on the surface of the receiving frame. The rubber plate is in contact with the inner wall of the tank. The number of rubber plates is set to three, and they are arranged in a circular array along the center of the receiving frame. When the round rod rotates, it drives the receiving frame to rotate, and the rotation of the receiving frame drives the rubber plate to rotate.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This invention utilizes a pre-treatment mechanism. Waste paper is fed onto a vibrating plate, causing the plate to oscillate and vibrate. A magnetic roller rotates and moves simultaneously. The recycled paper may contain impurities such as staples and plastic film, which can easily jam the shredder or damage the agitator blades, leading to machine downtime. Vibration separates these impurities, which are then attracted by the magnetic roller, while the impurities fall into a collection tank. The separated waste paper then enters a shredder for further shredding and subsequently enters a tank for further processing. This design protects the shredder from hard impacts and entanglement, reducing the failure rate and extending its service life. If the staples separated by vibration fall directly, they may mix into subsequent paper scraps or the bottom of the equipment, forming secondary impurities. The magnetic roller, through its reciprocating movement, covers the entire material feeding area below the vibrating plate, attracting the staples to the roller surface and preventing them from scattering.

[0017] This invention utilizes a stirring mechanism. After waste paper enters the tank, it is mixed by stirring blades. Even after the recycled paper is initially crushed by a shredder, some fiber bundles or clumps may still remain. Traditional stirring blades can only push the material flow by rotation, making it difficult to break up hard or dense clumps. The blades, however, rotate with the stirring blades to shear and cut the clumps, severing or tearing the fiber bundles and breaking down large clumps into fine paper scraps. Material accumulation on the inner wall of the tank can obstruct the flow of materials, creating a flow blind zone. This means that the material near the inner wall is difficult to be moved by the stirring blades and mixes unevenly with the material in the central area. The rotating rubber plate pushes the material scraped off the inner wall back into the stirring zone, increasing the overall flow speed of the material in the tank and preventing uneven fiber dispersion caused by localized material retention.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1-5 As shown, a recycled paper shredding device with a high-efficiency stirring mechanism includes a fixed frame 1, a tank 2 fixedly installed on the inner wall of the fixed frame 1, a baffle 3 fixedly installed on the top of the tank 2, a discharge port 4 opened on the outer wall of the tank 2, a shredder 5 installed on the inner wall of the baffle 3, a pretreatment mechanism 6 installed on the front side of the baffle 3, the pretreatment mechanism 6 includes a connecting frame 60, the connecting frame 60 is fixedly installed on the front side of the baffle 3, a vibrating plate 61 is slidably installed on the inner wall of the connecting frame 60, a spring seat 62 is provided between the vibrating plate 61 and the connecting frame 60, and a fixed end of a vibration motor 63 is provided on the surface of the vibrating plate 61. Recycled paper may contain impurities such as staples and plastic film, which can easily jam the shredding wheel or damage the stirring blade, causing the machine to stop. These impurities are separated by vibration.

[0027] The number of spring seats 62 is set to four, in pairs, and symmetrical to each other along the vertical central axis of the connecting frame 60. The number of vibration motors 63 is set to two, and symmetrical to each other along the vertical central axis of the connecting frame 60.

[0028] The surface of the connecting frame 60 is provided with a reciprocating lead screw 64, and a sliding button 65 is threaded on the circumferential surface of the reciprocating lead screw 64. The number of reciprocating lead screws 64 and sliding buttons 65 is set to two, and they are symmetrical to each other along the vertical central axis of the connecting frame 60.

[0029] The inner wall of the sliding button 65 is fixedly installed with the fixed end of the servo motor 66, and the output end of the servo motor 66 is fixedly installed with the magnetic suction roller 67. If the staples separated by vibration fall directly, they may mix into subsequent paper scraps or the bottom of the equipment, forming secondary impurities. The magnetic suction roller 67 can cover the entire material dropping area below the vibrating plate 61 by reciprocating movement, adsorbing the staples on the roller surface and preventing them from scattering.

[0030] The inner wall of the connecting frame 60 is provided with a sliding groove, and a collection tank 68 is slidably installed on the surface of the sliding groove, so that impurities fall into the collection tank 68.

[0031] According to the above structure, waste paper is input from the vibrating plate 61, which starts the vibrating motor 63 and causes it to vibrate. This vibrating plate 61 then shakes, compressing the spring seat 62, which then resets. The vibrating plate 61 vibrates while shaking. Simultaneously, the reciprocating screw 64 rotates, moving the sliding button 65. The sliding button 65 then moves the servo motor 66, which in turn moves the magnetic roller 67. The magnetic roller 67 rotates and moves simultaneously. Since the recycled paper may contain impurities such as staples and plastic film, these impurities can easily cause the shredder to jam. Damage to the stirring blades causes the machine to stop. These impurities are separated by vibration and then attracted by the magnetic roller 67, while the impurities fall into the collection tank 68. The separated waste paper enters the shredder 5 for shredding and then enters the tank 2 for further processing. This protects the shredder 5 from hard impacts and entanglement, reduces the failure rate, and improves its service life. If the staples separated by vibration fall directly, they may mix into subsequent paper scraps or the bottom of the equipment, forming secondary impurities. The magnetic roller 67 can cover the entire material dropping area below the vibrating plate 61 by reciprocating movement, attracting the staples to the roller surface and preventing them from scattering.

[0032] like Figure 1-5 As shown, the tank 2 is equipped with a stirring mechanism 7. The stirring mechanism 7 includes a fixed end of a servo motor 70. A round rod 71 is fixedly installed at the output end of the servo motor 70. A stirring blade 72 is fixedly installed on the circumferential surface of the round rod 71. The surface of the stirring blade 72 is provided with a cutting surface. There are two stirring blades 72, which are symmetrical to each other along the vertical central axis of the round rod 71. By rotating with the stirring blade 72, the cutting surface can perform shearing and cutting action on the agglomerates, cut or tear the fiber bundles, and decompose the large clumps into fine paper scraps.

[0033] A receiving frame 73 is fixedly installed on the circumferential surface of the round rod 71. A rubber plate 74 is fixedly installed on the surface of the receiving frame 73. The rubber plate 74 contacts the inner wall of the tank 2. The number of rubber plates 74 is set to three and arranged in a circular array along the center of the receiving frame 73. The accumulation of material on the inner wall of the tank will hinder the flow of material, resulting in a flow blind zone in the tank. That is, the material near the inner wall is difficult to be driven by the stirring plate 72 and is not mixed evenly with the material in the central area. By rotating the rubber plate 74, the material scraped off the inner wall is pushed back into the stirring zone, thereby increasing the overall flow speed of the material in the tank and avoiding uneven fiber dispersion caused by local material retention.

[0034] According to the above structure, after the waste paper enters the tank 2, the output end of the servo motor 70 rotates, driving the round rod 71 to rotate. The rotation of the round rod 71 drives the stirring plate 72 to rotate, thus mixing the waste paper. At the same time, the rotation of the round rod 71 drives the receiving frame 73 to rotate, and the rotation of the receiving frame 73 drives the rubber plate 74 to rotate. After the recycled paper is initially crushed by the shredder 5, some fiber bundles or clumps may still remain. The traditional stirring plate 72 can only push the material flow by rotation, which is difficult to break up hard or dense clumps. On one hand, the cutting blade, rotating with the stirring plate 72, can shear and cut the clumps, severing or tearing the fiber bundles and breaking down large clumps into fine paper scraps. The accumulation of material on the inner wall of the can will hinder the flow of materials, resulting in a flow blind zone in the can. That is, the material near the inner wall is difficult to be driven by the stirring plate 72 and is not mixed evenly with the material in the central area. The rotating rubber plate 74 pushes the material scraped off the inner wall back into the stirring zone, thereby increasing the overall flow speed of the material in the can and avoiding uneven fiber dispersion caused by local material retention.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
