Description

Technical Field

[0001] This utility model relates to the field of waste paper pulping technology, and in particular to a waste paper pulping machine for papermaking. Background Technology

[0002] Waste paper recycling refers to the process of converting waste paper into reusable recycled pulp through a series of processes such as collection, sorting, and treatment, and then producing new paper products. It is of great significance to environmental protection and sustainable economic development. Waste paper pulping machines are key equipment in the waste paper recycling process.

[0003] Waste paper pulping machines mainly consist of a pulping tank, a drive system, a feeding and discharging device, and a screening device. Through mechanical, physical, or chemical actions, they separate and disperse the fibers in waste paper, remove impurities, and ultimately form a pulp suspension that can be used for papermaking. During the shredding process, some paper scraps adhere to the inner wall of the container due to centrifugal force, preventing them from being fully shredded by the blades and affecting the quality of the pulp. Even with the addition of a screen at the discharge port to trap the shredded paper, allowing for sorting and recycling for repulping, production efficiency is significantly reduced, and pulping costs increase. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a waste paper pulping machine for papermaking, which aims to improve the problem in the prior art where some paper scraps adhere to the inner wall of the container and cannot be fully shredded by the blades, affecting the quality of the pulp, reducing production efficiency, and increasing pulping costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waste paper pulping machine for papermaking, comprising a pulping tank and a feed inlet, wherein a pulping and cleaning mechanism is provided on the upper part of the pulping tank for separating fibers from waste paper, and an auxiliary feeding mechanism is provided above the feed inlet for promoting feeding and unblocking the feed inlet; the pulping and cleaning mechanism includes a first motor, which is fixedly connected to the top of the outer wall of the pulping tank, and a first gear is fixedly connected to the output end of the first motor.

A transmission shaft is fixedly connected to the middle of the second gear, and multiple fixing blocks are fixedly connected to the middle of the transmission shaft. Fixing rods are fixedly connected to both the left and right sides of each fixing block, and a blade is fixedly connected to the middle of each fixing rod. A brush is fixedly connected to the front end of each fixing rod.

A sliding rod is rotatably connected to the bottom end of the connecting plate. A pressure plate is fixedly connected to the bottom of the sliding rod. A fixing plate is fixedly connected to the upper right side of the outer wall of the pulping tank. A guide tube is fixedly connected to the front end of the fixing plate. The guide tube is slidably connected to the sliding rod.

[0008] As a further description of the above technical solution:

[0019] The bottom wall of the pulping tank is fixedly connected with multiple support columns, and the bottom end of each support column is fixedly connected with an anti-slip pad.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, starting the first motor causes the first gear to rotate, which in turn drives the transmission shaft at the bottom to rotate, thereby causing the blade and brush to rotate. The blade separates the fibers in the waste paper, and the brush scrapes off the waste paper attached to the inner wall, allowing the blade to fully crush the paper. During the rotation process, the blade can also clean the dirt attached to the inner wall, improve the quality of the pulp, increase production efficiency, and reduce pulping costs.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a waste paper pulping machine for papermaking, comprising a pulping tank 1 and a feed inlet 4. A pulping and cleaning mechanism 2 is provided on the upper part of the pulping tank 1 for separating fibers from waste paper. An auxiliary feeding mechanism 3 is provided above the feed inlet 4 to promote feeding and clear the feed inlet 4. The pulping and cleaning mechanism 2 includes a first motor 201, which is fixedly connected to the top of the outer wall of the pulping tank 1. A first gear 202 is fixedly connected to the output end of the first motor 201. Second gears 203 are provided on both the left and right sides of the first gear 202, and the second gears 203 mesh with the first gear 202. A drive shaft 204 is fixedly connected to the middle of the 203, rotating synchronously with the second gear 203. Multiple fixing blocks 205 are fixedly connected to the middle of the drive shaft 204. Fixing rods 206 are fixedly connected to the left and right sides of the fixing blocks 205. A blade 207 is fixedly connected to the middle of the fixing rod 206 for shredding waste paper. A brush 208 is fixedly connected to the front end of the fixing rod 206 to clean the shredded paper adhering to the wall of the pulping tank 1. A protective cover 5 is fixedly connected to the top of the outer wall of the pulping tank 1 to protect the first motor 201. An inspection window 6 is installed on the top of the protective cover 5 for easy maintenance. A fan 7 is fixedly connected to the left side of the protective cover 5 to dissipate heat from the first motor 201.

[0032] Specifically, the first motor 201 is started. The first motor 201 is a stepper motor. The received electrical pulse signals cause the stator windings to be energized in a specific sequence to generate a rotating magnetic field, which drives the rotor to rotate at a fixed angle. By controlling the pulse sequence and frequency, forward and reverse rotation, speed adjustment, and precise positioning can be achieved. The operation of the first motor 201 drives the first gear 202 to rotate. Since the first gear 202 and the second gears 203 on both sides are in a meshing state, the second gears 203 will rotate synchronously with the first gear 202, which in turn drives the transmission shaft 204 connected to it to rotate synchronously. The fixing block 205 fixed on the transmission shaft 204 will rotate around the transmission shaft 204. When the fixing block 205 rotates, it will drive the fixing rod 206 connected to it to rotate synchronously. The fixing rod 206 drives the blade 207 and brush 208 connected to it to rotate accordingly. The rotating blades 207 cut and shred the waste paper in the pulping tank 1, separating the fibers from the waste paper. The brush 208, during rotation, contacts the inner wall of the pulping tank 1, scraping off the waste paper adhering to the inner wall so that it can be fully shredded by the blades 207. At the same time, the brush 208 can also clean the dirt adhering to the inner wall during rotation, preventing dirt accumulation. The protective cover 5 outside the first motor 201 can isolate the first motor 201 from the external environment, preventing external dust from affecting the motor operation. The inspection window 6 facilitates the inspection and maintenance of the first motor 201 by the staff. The fan 7 is a 220AC AC fan 7, which drives the impeller to rotate through an AC motor to achieve directional airflow, dissipating the heat generated by the first motor 201 during operation in a timely manner, preventing the motor from malfunctioning due to overheating.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The auxiliary feeding mechanism 3 includes a second motor 301, which is fixedly connected to the top right side of the outer wall of the pulping tank 1. A rocker arm gear 302 is fixedly connected to the output end of the second motor 301. A connecting plate 303 is rotatably connected to the front end of the rocker arm gear 302. A slide rod 304 is rotatably connected to the bottom end of the connecting plate 303. A pressure plate 305 is fixedly connected to the bottom of the slide rod 304 for pushing waste paper. A fixing plate 306 is fixedly connected to the upper right side of the outer wall of the pulping tank 1. A guide tube 307 is fixedly connected to the front end of the fixing plate 306 to restrict the movement direction of the slide rod 304. The guide tube 307 is slidably connected to the slide rod 304. A feed trough 8 is fixedly connected to the front end of the feed inlet 4 so that the waste paper enters the feed inlet 4 along the feed trough 8.

[0034] Specifically, the waste paper to be processed and water are poured into the feed trough 8 together. The waste paper will slide down the inclined surface of the feed trough 8 into the feed inlet 4. The second motor 301 is started. The second motor 301 is a stepper motor. The stator winding is energized in a specific sequence by the received electrical pulse signal to generate a rotating magnetic field, which drives the rotor to rotate at a fixed angle. By controlling the pulse sequence and frequency, forward and reverse rotation, speed adjustment and precise positioning can be achieved. The operation of the second motor 301 drives the rocker arm gear 302 to rotate. The connecting plate 303 will rotate in the same direction as the rocker arm gear 302. During the rotation of the connecting plate 303, a downward force is applied to the slide rod 304 connected to it. Since the guide tube 307 restricts the movement direction of the slide rod 304, the slide rod 304 will move downward along the inner wall of the guide tube 307. At the same time, it drives the pressure plate 305 installed at its bottom to move downward synchronously. When the pressure plate 305 moves downward, it pushes the waste paper in the feed inlet 4 into the feed pipe below to prevent it from accumulating in the feed inlet 4 and causing blockage.

[0035] Reference Figure 1 , Figure 2 and Figure 5 The pulping tank 1 has a shut-off valve 9 connected to the middle of its inner bottom wall to control the conveying of pulp; a screen 10 is fixedly connected to the top of the shut-off valve 9 to filter impurities in the pulp; multiple support columns 11 are fixedly connected around the bottom wall of the pulping tank 1 to support the tank body, and anti-slip pads 12 are fixedly connected to the bottom end of the support columns 11 to prevent the pulping tank 1 from sliding.

[0036] Specifically, after the pulp preparation is completed, the shut-off valve 9 is opened. The shut-off valve 9 is an electric flange gate valve, which is driven by an electric actuator to rotate the motor in both directions. Through deceleration transmission, the valve stem moves the gate plate up and down to realize the opening and closing of the pipeline. The start and stop are controlled by a limit switch. The pulp will flow downward through the screen 10. The screen 10 will filter the pulp, allowing it to flow out through the mesh of the screen 10. Impurities and paper scraps contained in the pulp will be blocked above by the screen 10, thereby ensuring that the quality of the flowing pulp meets the requirements of papermaking. The anti-slip pad 12 at the bottom of the support column 11 can increase the friction between the support column 11 and the ground, preventing the pulping tank 1 from sliding due to vibration or other reasons during operation, and ensuring the stability of the tank.

[0037] Working principle: Waste paper and water are poured into the feed trough 8. The waste paper slides down the feed trough 8 into the feed inlet 4. The second motor 301 is started to rotate the rocker arm gear 302, which causes the connecting plate 303 connected to it to rotate in the same direction. At the same time, the connecting plate 303 will apply a downward force to the slide rod 304. The guide tube 307 restricts the movement direction of the slide rod 304. The slide rod 304 will move downward, driving the pressure plate 305 to move downward, pushing the waste paper into the feed tube below the feed inlet 4.

[0038] The first motor 201 is started, causing the first gear 202 to rotate. Since the first gear 202 and the second gears 203 on both sides are in a meshing state, the second gears 203 will rotate synchronously with the first gear 202, driving the transmission shaft 204 to rotate. As a result, the fixed block 205 rotates around the transmission shaft 204. The fixed block 205 will drive the fixed rod 206 connected to it to rotate synchronously, thereby causing the blade 207 and brush 208 connected to it to rotate. The blade 207 will shred the waste paper in the pulping tank 1 and separate the fibers in the waste paper. The brush 208 contacts the inner wall of the pulping tank 1, scraping off the waste paper attached to the inner wall and allowing the blade 207 to shred it thoroughly. At the same time, during the rotation, it can also clean the dirt attached to the inner wall. When the pulp is prepared, the shut-off valve 9 is opened, and the pulp will flow out through the screen 10. The impurities in the pulp will be blocked by the screen 10, ensuring that the quality of the pulp meets the requirements of papermaking.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
