Description

Technical Field

[0001] This utility model relates to the field of packaging paper processing, and in particular to a packaging paper pulp crushing device. Background Technology

[0002] With continued economic development, the demand for packaging paper is constantly increasing across various industries. To meet the needs of large-scale packaging paper production, higher demands are placed on the efficiency and quality of pulp milling equipment. This equipment needs to be able to efficiently mill the pulp into suitable particle sizes to ensure the quality and quantity of subsequent packaging paper production. Against the backdrop of increasingly stringent environmental policies, the packaging paper industry is increasingly inclined to use environmentally friendly raw materials such as recycled fibers. However, the characteristics of these raw materials differ from traditional wood pulp, requiring specialized pulp milling equipment for processing to achieve better fiber separation and milling effects, while simultaneously reducing energy consumption and waste emissions.

[0003] Traditional pulp pulverizing equipment for packaging paper processing only has the basic function of pulverizing packaging paper pulp. Although it can pulverize packaging paper pulp to a certain extent, it also has many limitations. First, when the pulp needs to be screened after pulverization, the pulp will cause blockage on the screen plate, significantly slowing down the speed at which the pulp passes through the screen plate, resulting in a decrease in the processing capacity of the screening process and a reduction in work efficiency.

[0004] Secondly, it will cause the pulp to accumulate above the sieve plate, and pulps of different particle sizes and properties cannot pass through the sieve plate in a timely and uniform manner. This may result in uneven mixing of the pulp in subsequent processing, affecting the uniformity, strength and other quality indicators of the packaging paper.

[0005] In addition, fibers and impurities in the pulp may adhere tightly to the screen plate, causing the screen plate to become clogged. The filtration effect gradually decreases, the pulp passes through the screen plate more and more slowly, the screening efficiency decreases, and this affects all aspects of subsequent packaging paper production, reducing overall work efficiency.

[0006] In summary, existing pulp pulverizing devices for packaging paper processing are insufficient in both cleaning and screening effects, failing to meet the requirements for pulverizing pulp in packaging paper processing. Therefore, developing a pulp pulverizing device for packaging paper processing that allows the pulp to flow dynamically on the screen plate, preventing the accumulation and clumping of fibers and impurities in the pulp, effectively preventing screen plate blockage, ensuring that the screen holes remain unobstructed, and enabling the screening process to proceed continuously and stably is of significant practical importance. Utility Model Content

[0007] To overcome the technical problem that when the pulp is crushed and then screened, it can cause blockage on the screen plate, significantly slowing down the speed at which the pulp passes through the screen plate, thus reducing the processing capacity of the screening process and lowering work efficiency.

[0008] The technical solution of this utility model is as follows: a pulp crushing device for packaging paper processing, including a shell, a connecting frame, and a stirring assembly. The stirring assembly is arranged inside the shell, and the connecting frame is arranged outside the shell. A first motor is arranged above the connecting frame, and a first pulley is arranged at the output end of the first motor. A second pulley is arranged outside the shell, and there are two sets of the second pulleys on both sides of the first pulley. A first transmission belt is connected above the first pulley and the second pulley. A rotating rod is arranged inside the shell, and there are three sets of the rotating rods. The three sets of rotating rods are respectively connected to the first pulley and the second pulley through a rotating shaft. A stirring blade is arranged above the three sets of rotating rods, and there are multiple sets of stirring blades.

[0009] Preferably, a crushing chamber is provided on the top of the outer shell, and a feed inlet is provided on the top of the crushing chamber.

[0010] Preferably, a fixed frame is provided on the outside of the crushing box, a second motor is provided on the upper part of the fixed frame, a third pulley is provided at the output end of the second motor, and the third pulley is located on the outside of the crushing box. A fourth pulley is provided on the outside of the crushing box, and a second transmission belt is provided above the third pulley and the fourth pulley. A crushing roller is provided inside the crushing box, and two sets of crushing rollers are provided. The two sets of crushing rollers are respectively connected to the third pulley and the fourth pulley through a rotating shaft.

[0011] Preferably, the interior of the outer casing is provided with an inclined screen plate, and the other side of the inclined screen plate is provided with a discharge port.

[0012] Preferably, a collection trough is provided below the inclined screen plate, and the collection trough is located at the bottom of the outer casing.

[0013] Preferably, the outer casing has a support plate inside, a fixing block is provided above the support plate, the fixing block has a groove inside, a spring is provided inside the groove, and the outer diameter of the spring is smaller than the diameter of the groove. A baffle is fixedly connected to the other side of the spring, and the width of the baffle is equal to the width of the groove. A sliding rod is provided above the baffle, a pushing block is provided above the sliding rod, and a rack is provided on one side of the sliding rod.

[0014] Preferably, a third motor is provided on the outer side of the housing, and a half gear is provided at the output end of the third motor, and the half gear is meshed with the rack.

[0015] The beneficial effects of this utility model: Through ingenious structural design, this utility model achieves a combination of cleaning and screening effects. On the one hand, starting the first motor drives the first pulley to rotate, which in turn drives two sets of first transmission belts to rotate, which in turn drives the second pulley to rotate, causing the three sets of rotating rods to rotate inside the outer shell. The rotation of the rotating rods drives the stirring blades to rotate above the rotating rods, which can stir the crushed pulp and keep the pulp in a dynamic flow state on the screen plate. This prevents fibers and impurities in the pulp from accumulating and clumping on the screen plate, thereby effectively preventing screen plate blockage and ensuring that the screen holes of the screen plate remain unobstructed, so that the screening process can proceed continuously and stably.

[0016] On the other hand, starting the third motor drives the half gear to rotate. The rotation of the half gear drives the rack downward, which in turn drives the sliding rod downward. The downward movement of the sliding rod causes the spring inside the fixed block to contract downward. When the half gear rotates to the position where it separates from the rack above the sliding rod, the sliding rod returns to its original position under the action of the spring, causing it to move upward. The upward movement of the sliding rod causes the pushing block to collide with the inclined screen plate. This allows for the cleaning of any remaining impurities above the inclined screen plate after the device has finished working. By tapping the inclined screen plate, the particles on it fall into the collection tank at the bottom of the outer casing, which can then be cleaned manually. Attached Figure Description

Two sets of second pulleys 104 are disposed outside the housing 1, and are located on both sides of the first pulleys 103. A first transmission belt 105 is connected above the first pulleys 103 and the second pulleys 104. Three sets of rotating rods 106 are disposed inside the housing 1, and the three sets of rotating rods 106 are respectively connected to the first pulleys 103 and the second pulleys 104 via rotating shafts. Next, stirring blades 107 are installed above the three sets of rotating rods 106. There are multiple sets of stirring blades 107. When the first motor 102 is started, it drives the first pulley 103 to rotate. The rotation of the first pulley 103 drives the two sets of first transmission belts 105 to rotate. The rotation of the first transmission belts 105 drives the second pulley 104 to rotate, so that the three sets of rotating rods 106 rotate inside the outer shell 1. The rotation of the rotating rods 106 drives the stirring blades 107 to rotate above the rotating rods 106. This can stir the pulverized pulp, so that the pulp is in a dynamic flow state on the screen plate. This prevents the accumulation and agglomeration of fibers and impurities in the pulp on the screen plate, thereby effectively preventing the screen plate from clogging and ensuring that the screen holes of the screen plate are always unobstructed, so that the screening process can be carried out continuously and stably.

[0024] Please see Figures 1-3In this embodiment, a crushing chamber 2 is provided above the outer casing 1, and a feed inlet 3 is provided above the crushing chamber 2. A fixing frame 201 is provided on the outside of the crushing chamber 2, and a second motor 202 is provided on the upper part of the fixing frame 201. A third pulley 203 is provided at the output end of the second motor 202, and the third pulley 203 is located on the outside of the crushing chamber 2. A fourth pulley 204 is provided on the outside of the crushing chamber 2. A second transmission belt 205 is provided above the third pulley 203 and the fourth pulley 204. A crushing roller is provided inside the crushing chamber 2. 206. Two sets of crushing rollers 206 are provided. The two sets of crushing rollers 206 are respectively connected to the third pulley 203 and the fourth pulley 204 through rotating shafts. When the second motor 202 is started, the third pulley 203 is driven to rotate. The rotation of the third pulley 203 drives the second transmission belt 205 to rotate. The rotation of the second transmission belt 205 drives the fourth pulley 204 to rotate. The rotation of the third pulley 203 and the fourth pulley 204 causes the two sets of crushing rollers 206 to rotate inside the crushing box 2, which can crush the packaging paper pulp.

[0025] Please see Figures 2-4In this embodiment, an inclined screen plate 4 is provided inside the outer casing 1, and a discharge port 5 is provided on the other side of the inclined screen plate 4. A collection trough 6 is provided below the inclined screen plate 4 and is located at the bottom of the outer casing 1. Qualified pulp particles will fall into the collection trough 6 through the inclined screen plate 4. The operator then removes the collection trough 6 from the outer casing 1 to process the qualified pulp particles for the next step. Unqualified pulp particles will pass through the inclined screen plate 4 and be discharged from the discharge port 5, allowing the operator to collect the unqualified pulp particles. The unqualified pulp is then processed. The particles are then placed back into the crushing chamber 2 for further crushing, ensuring the consistency of the original pulp particles. Inside the outer shell 1, a support plate 301 is installed. Above the support plate 301, a fixing block 302 is installed. A groove is formed inside the fixing block 302, and a spring 303 is installed inside the groove. The outer diameter of the spring 303 is smaller than the diameter of the groove. A baffle 304 is fixedly connected to the other side of the spring 303, and the width of the baffle 304 is equal to the width of the groove. A sliding rod 305 is installed above the baffle 304, and a pushing rod is installed above the sliding rod 305. Block 306, a rack 307 is provided on one side of the sliding rod 305, and a third motor 308 is provided on the outer side of the outer casing 1. The output end of the third motor 308 is provided with a half gear 309, and the half gear 309 is meshed with the rack 307. When the third motor 308 is started, it drives the half gear 309 to rotate. The rotation of the half gear 309 drives the rack 307 to move downward. The downward movement of the rack 307 drives the sliding rod 305 to move downward. The downward movement of the sliding rod 305 drives the spring 303 inside the fixed block 302 to move downward. When the half gear 309 rotates to the position where it separates from the rack 307 above the sliding rod 305, the sliding rod 305 is reset under the action of the spring 303, causing the sliding rod 305 to move upward. The upward movement of the sliding rod 305 drives the pushing block 306 to collide with the inclined screen plate 4 upward. This can clean the impurities remaining on the inclined screen plate 4 after the device has finished working. By tapping the inclined screen plate 4, the particles on the inclined screen plate 4 fall into the collection tank 6 at the bottom of the outer shell 1, and then the collection tank 6 is cleaned manually.

[0026] During operation, the first motor 102 is started, driving the first pulley 103 to rotate. The rotation of the first pulley 103 drives the two sets of first transmission belts 105 to rotate, which in turn drives the second pulley 104 to rotate. This causes the three sets of rotating rods 106 to rotate inside the outer casing 1. The rotation of the rotating rods 106 drives the stirring blades 107 to rotate above the rotating rods 106, thus stirring the pulverized pulp. This keeps the pulp in a dynamic flow state on the screen plate, preventing fibers and impurities from accumulating and clumping on the screen plate, thereby achieving... To effectively prevent sieve plate clogging and ensure that the sieve holes remain unobstructed, allowing the screening process to proceed continuously and stably, the second motor 202 is started, driving the third pulley 203 to rotate. The rotation of the third pulley 203 drives the second transmission belt 205 to rotate, which in turn drives the fourth pulley 204. The rotation of the third pulley 203 and the fourth pulley 204 causes the two sets of crushing rollers 206 to rotate inside the crushing box 2, which crushes the packaging paper pulp. Pulp particles of the correct size fall through the inclined sieve plate 4 into the collection tank 6. In the next step, the staff removes the collection tank 6 from the outer shell 1 to process the qualified raw pulp particles for the next step. The unqualified raw pulp particles will pass through the inclined screen plate 4 and be discharged from the discharge port 5. The staff collects the unqualified raw pulp particles and puts them back into the crushing box 2 for crushing to ensure the consistency of the raw pulp particles. The third motor 308 is started to drive the half gear 309 to rotate. The rotation of the half gear 309 drives the rack 307 to move downward. The downward movement of the rack 307 drives the sliding rod 305 to move downward. The downward movement of the sliding rod 305 drives the... The spring 303 inside the moving fixed block 302 retracts downward. When the half gear 309 rotates to the position where it separates from the rack 307 above the sliding rod 305, the sliding rod 305 resets under the action of the spring 303, causing the sliding rod 305 to move upward. The upward movement of the sliding rod 305 drives the pushing block 306 to collide with the inclined screen plate 4 upward. This allows for the cleaning of impurities remaining on the inclined screen plate 4 after the device has finished working. By tapping the inclined screen plate 4, the particles on the inclined screen plate 4 fall into the collection tank 6 at the bottom of the outer shell 1, and the collection tank 6 is then cleaned manually.

[0027] Through the above steps, the first motor 102 is started, driving the first pulley 103 to rotate. The rotation of the first pulley 103 drives the two sets of first transmission belts 105 to rotate. The rotation of the first transmission belts 105 drives the second pulley 104 to rotate, causing the three sets of rotating rods 106 to rotate inside the outer casing 1. The rotation of the rotating rods 106 drives the stirring blades 107 to rotate above the rotating rods 106, which can stir the crushed pulp and keep the pulp in a dynamic flow state on the screen plate. This prevents fibers, impurities, etc. in the pulp from accumulating and clumping on the screen plate, thereby effectively preventing screen plate blockage and ensuring that the screen holes of the screen plate always remain unobstructed, so that the screening process can continue to proceed stably.
