Technical Field

[0001] This invention relates to the field of kraft paper production technology, specifically to a kraft paper production anti-overcutting pulping machine. Background Technology

[0002] The pulping machine for kraft paper production is a core piece of equipment specifically designed for the preparation of kraft paper raw materials. Through a rational configuration of the feeding device, cooking system, crushing and dissociation mechanism, screening and purification unit, and unloading components, it achieves continuous processing from wood fibers to qualified pulp. During operation, the feeding device first evenly conveys the raw materials to the cooking system. Under high temperature, high pressure, and chemical agents, the lignin bonds between fibers are broken down. The crushing and dissociation mechanism then breaks down the cooked raw materials into individual fibers. Subsequently, the screening and purification unit removes impurities and undissociated fiber bundles, ultimately outputting high-purity, high-strength pulp that meets the requirements of kraft paper production. This equipment adopts a modular design, allowing for flexible adjustment of processing parameters according to production scale. It features stable operation, high fiber utilization, and outstanding pulping efficiency, effectively meeting the toughness and tear resistance requirements of kraft paper. It provides a high-quality raw material guarantee for subsequent papermaking processes and is widely used in the front-end pulping stage of various kraft paper production lines.

[0011] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0012] Example 1, please refer to Figures 1-2 This invention provides a technical solution: a pulping machine for kraft paper production that prevents excessive cutting, comprising: Pulping machine 1, with a cleaning component 3 fixedly connected to the bottom of pulping machine 1; Conveying component 2 is used to cut and convey the slurry, and is fixedly connected to the side of the pulping machine 1. Please see Figure 3 The conveying component 2 includes a conveying frame 21, which is fixedly connected to the side of the pulping machine 1. Conveying roller 22 is rotatably connected to both sides of the conveying frame 21, and conveying roller 23 is rotatably connected to both sides of the top of the conveying frame 21. A cutting mechanism 24 is fixedly connected to the inner side of the conveying frame 21. Please see Figure 4 The cutting mechanism 24 includes a cutting frame 241, the side of the cutting frame 241 is fixedly connected to the inner side of the conveyor frame 21, a support frame 242 is fixedly connected to the top of the cutting frame 241, a top plate 243 is fixedly connected to the top of the support frame 242, a driving component 244 is fixedly connected to the top of the top plate 243, the output end of the driving component 244 is fixedly connected to the top of the moving component 245, the moving component 245 is slidably connected to both sides of the support frame 242, and a clearance groove 246 is provided in the middle of the cutting frame 241; Please see Figure 5 The moving component 245 includes a moving frame 2451, the inner side of which is slidably connected to the side of the support frame 242, the top of which is fixedly connected to the output end of the drive component 244, a cutter 2452 fixedly connected to the bottom of the moving frame 2451, a connecting housing 2453 fixedly connected to both sides of the moving frame 2451, a connecting rod 2454 slidably connected to the inner side of the connecting housing 2453, a connecting plate 2455 fixedly connected to the bottom of the connecting rod 2454, a moving roller 2456 rotatably connected to the bottom of the connecting plate 2455, a connecting rod 2457 fixedly connected to the top of the connecting rod 2454, a first spring 2458 sleeved on the connecting rod 2457, the top of the first spring 2458 fixedly connected to the inner side of the connecting housing 2453, and the bottom of the first spring 2458 fixedly connected to the side of the connecting rod 2454. When the pulp is conveyed through the conveyor frame 21, the conveyor rollers 22 and 23 on both sides of the conveyor frame 21 form a close contact guide to ensure that the pulp is conveyed smoothly and without deviation. The cutting mechanism 24 is started synchronously. The output end of the drive component 244 drives the cutter 2452 to move downward along the support frame 242 through the moving frame 2451, and cuts the pulp between the first conveyor roller 22 and the second conveyor roller 23 to achieve fixed-length cutting of the pulp, meet the requirements of subsequent kraft paper production for fiber length adaptation, and improve cutting efficiency and dimensional consistency. When the moving frame 2451 drives the cutter 2452 to move down and cut, it will simultaneously drive the connecting plate 2455 to move down through the connecting housing 2453 on both sides and the connecting rod 2454, so that the moving roller 2456 on the connecting plate 2455 comes into contact with the continuously conveyed pulp. As the drive component 244 continues to drive the moving frame 2451 downward, the moving roller 2456 always maintains contact with the pulp being conveyed. This design can provide stable support and positioning for the pulp, preventing the pulp from shifting or wrinkling when the cutter 2452 cuts, further improving the flatness of the cut. At the same time, it can comb the pulp fibers in advance, reducing the fiber entanglement phenomenon during cutting. When the contact pressure between the moving roller 2456 and the pulp is too great, the moving roller 2456 will drive the connecting rod 2454 to move within the connecting housing 2453 through the connecting plate 2455, thereby pushing the connecting rod 2457 to move upward within the connecting housing 2453 and squeezing the first spring 2458 sleeved on the connecting rod 2457, absorbing the excess pressure through the elastic deformation of the spring; Example 2, please refer to Figure 6 Based on Embodiment 1, the present invention provides a technical solution: The cleaning component 3 includes a cleaning housing 31, an air intake 33 is fixedly connected to the bottom of the inner cavity of the cleaning housing 31, a mesh plate 32 is fixedly connected to the top of the air intake 33, a rotating mechanism 34 is rotatably connected to the top of the mesh plate 32, and a contact mechanism 35 is fixedly connected to the inner side of the cleaning housing 31. When the pulp in the pulper 1 is moved by the conveyor belt, the conveyor belt rotates synchronously with the operation of the equipment, and its side forms a close contact movement with the contact mechanism 35 inside the cleaning shell 31. The contact mechanism 35 cleans the slurry residue and fiber debris attached to the side of the conveyor belt. During the contact cleaning process, the suction machine 33 is turned on at the same time. The negative pressure suction generated during its operation is used to adsorb and collect the fiber debris and impurities that fall during the cleaning process, so that the impurities are quickly sucked into the cleaning shell 31 for centralized storage. Meanwhile, during the impurity collection stage, the rotating mechanism 34 inside the cleaning shell 31 is started and rotates continuously to scrape and clean the inner wall of the cleaning shell 31, preventing the adsorbed impurities from accumulating and clumping on the inner wall of the shell, ensuring sufficient collection space inside the shell, avoiding the impact of impurity accumulation on the adsorption efficiency of the inhaler 33, extending the continuous running time of the cleaning mechanism, and reducing the frequency of manual cleaning and maintenance. Please see Figure 7 The contact mechanism 35 includes a contact frame 351 and a filter plate 354. The side of the contact frame 351 is slidably connected to the inside of the cleaning housing 31. Scrapers 352 are fixedly connected to both sides of the top of the contact frame 351. Contact rollers 353 are rotatably connected to both sides of the contact frame 351. Slide rods 355 are fixedly connected to both sides of the bottom of the contact frame 351. The bottom of the slide rods 355 is slidably connected to the inside of the filter plate 354. A second spring 356 is sleeved on the slide rods 355. The top of the second spring 356 is fixedly connected to the bottom of the contact frame 351. The bottom of the second spring 356 is fixedly connected to the top of the filter plate 354. The side of the filter plate 354 is fixedly connected to the inside of the cleaning housing 31. When the conveyor belt rotates synchronously in the pulper 1, its side surface forms a close contact movement with the contact rollers 353 on both sides of the contact frame 351, and at the same time, the scrapers 352 on both sides of the top center of the contact frame 351 slide closely against the side surface of the conveyor belt. When the contact pressure between the scraper 352 and the conveyor belt exceeds the preset threshold, the scraper 352 will drive the contact frame 351 to move downward along the slide bar 355, and simultaneously squeeze the second spring 356 sleeved on the slide bar 355. The excess pressure is absorbed by the elastic deformation of the spring, and the adhesion force between the scraper 352 and the conveyor belt is automatically adjusted. Please see Figures 8-9 The rotating mechanism 34 includes a rotating shaft 341, a fan blade fixedly connected to the bottom of the rotating shaft 341, a side of the rotating shaft 341 rotatably connected to the inner side of the screen plate 32, a top of the rotating shaft 341 rotatably connected to the bottom of the filter plate 354, a rotating housing 342 fixedly connected to both sides of the rotating shaft 341, a cleaning roller 343 rotatably connected to the inner side of the rotating housing 342, and cleaning rollers 343 arranged at the top and bottom respectively contacting the bottom of the filter plate 354 and the top of the screen plate 32. Baffles 344 are evenly arranged on the inner side of the rotating housing 342, and the side of the baffles 344 is fixedly connected to the inner side of the rotating housing 342. After the suction machine 33 is turned on, the negative pressure suction it generates will quickly capture the pulp debris that falls off the side of the conveyor belt when the scraper 352 and the contact roller 353 are cleaning it. Under the action of suction, the debris moves downward through the filter plate 354 and eventually falls onto the mesh plate 32 for collection. At the same time, the suction generated by the suction machine 33 will drive the fan blades at the bottom of the rotating shaft 341 to rotate, and the fan blades will further drive the rotating shaft 341 to rotate synchronously on the top of the mesh plate 32. The rotating shaft 341 rotates in a close-fitting manner with the top of the screen plate 32 and the bottom of the filter plate 354 through the rotating housings 342 on both sides, thereby driving the cleaning rollers 343 on the rotating housings 342 to roll and clean the top of the screen plate 32 and the bottom of the filter plate 354. As the cleaning roller 343 rotates inside the rotating housing 342, it will continuously contact and rub against the stop block 344 inside the housing. The stop block 344 can scrape off the pulp debris that accumulates on the rotating shaft 341, preventing the debris from accumulating and clumping on the rotating shaft 341, thus preventing it from interfering with the normal rotation and cleaning action of the cleaning roller 343 and ensuring the long-term stable operation of the cleaning mechanism.

[0013] Specific workflow: The wood raw materials are quantitatively and evenly conveyed to the cooking system through the feeding device. Under high temperature and high pressure, combined with the action of chemical agents such as caustic soda and sodium sulfide, the lignin between the fibers is efficiently removed, and the fibers are initially softened at the same time. After steaming and cooking, the raw materials enter the crushing and disintegration mechanism, where the fiber bundles are completely broken down into individual fibers through mechanical shearing and grinding, while loosening the impurities remaining between the fibers. The fiber pulp is transported to the screening and purification unit, where it undergoes multiple processes such as sieve filtration and centrifugation to precisely remove solid impurities such as bark, mud, and metal fragments, as well as undissociated fiber bundles, ensuring the purity of the pulp. The pulp is conveyed to the subsequent process by the conveying component 2. During the entire operation of the conveyor belt, the matching cleaning component 3 cleans the surface of the conveyor belt in a timely manner to remove residual pulp and prevent residual pulp from clumping and affecting the conveying accuracy of the conveyor belt. At the same time, it prevents residual pulp from mixing into the subsequent pulp and causing quality contamination, and ensures the long-term stable operation of the conveying system. When the pulp is conveyed through the conveyor frame 21, the conveyor rollers 22 and 23 on both sides of the conveyor frame 21 form a close contact guide to ensure that the pulp is conveyed smoothly and without deviation. The cutting mechanism 24 is started synchronously. The output end of the drive component 244 drives the cutter 2452 to move downward along the support frame 242 through the moving frame 2451, and cuts the pulp between the first conveyor roller 22 and the second conveyor roller 23 to achieve fixed-length cutting of the pulp, meet the requirements of subsequent kraft paper production for fiber length adaptation, and improve cutting efficiency and dimensional consistency. When the moving frame 2451 drives the cutter 2452 to move down and cut, it will simultaneously drive the connecting plate 2455 to move down through the connecting housing 2453 on both sides and the connecting rod 2454, so that the moving roller 2456 on the connecting plate 2455 comes into contact with the continuously conveyed pulp. As the drive component 244 continues to drive the moving frame 2451 downward, the moving roller 2456 always maintains contact with the pulp being conveyed. This design can provide stable support and positioning for the pulp, preventing the pulp from shifting or wrinkling when the cutter 2452 cuts, further improving the flatness of the cut. At the same time, it can comb the pulp fibers in advance, reducing the fiber entanglement phenomenon during cutting. When the contact pressure between the moving roller 2456 and the pulp is too great, the moving roller 2456 will drive the connecting rod 2454 to move within the connecting housing 2453 through the connecting plate 2455, thereby pushing the connecting rod 2457 to move upward within the connecting housing 2453 and squeezing the first spring 2458 sleeved on the connecting rod 2457, absorbing the excess pressure through the elastic deformation of the spring; To prevent excessive pressure between the moving roller 2456 and the pulp, which could lead to excessive compression and breakage of the fibers, thus ensuring the integrity of the pulp fibers, and at the same time ensuring that the moving roller 2456 always maintains a reasonable pressure against the pulp to maintain the auxiliary positioning effect, thus balancing positioning stability and pulp quality protection. When the pulp in the pulper 1 is moved by the conveyor belt, the conveyor belt rotates synchronously with the operation of the equipment, and its side forms a close contact movement with the contact mechanism 35 inside the cleaning shell 31. Contact mechanism 35 cleans the pulp residue and fiber debris adhering to the side of the conveyor belt to prevent the residual pulp from hardening and affecting the running accuracy of the conveyor belt, and to prevent residual impurities from mixing into the subsequent pulp and causing quality contamination. During the contact cleaning process, the suction machine 33 is turned on simultaneously. The negative pressure suction generated during its operation is used to adsorb and collect the fiber debris and impurities that fall during the cleaning process. This allows the impurities to be quickly sucked into the cleaning shell 31 for centralized storage, which not only prevents debris from flying and polluting the production environment and endangering the health of operators, but also prevents impurities from adhering to the conveyor belt or falling into the equipment and causing blockages. Meanwhile, during the impurity collection stage, the rotating mechanism 34 inside the cleaning shell 31 is started and rotates continuously to scrape and clean the inner wall of the cleaning shell 31, preventing the adsorbed impurities from accumulating and clumping on the inner wall of the shell, ensuring sufficient collection space inside the shell, avoiding the impact of impurity accumulation on the adsorption efficiency of the inhaler 33, extending the continuous running time of the cleaning mechanism, and reducing the frequency of manual cleaning and maintenance. When the conveyor belt rotates synchronously in the pulper 1, its side surfaces form a close contact with the contact rollers 353 on both sides of the contact frame 351. At the same time, the scrapers 352 on both sides of the top center of the contact frame 351 slide closely against the side surfaces of the conveyor belt. Through the dual cooperation of pre-cleaning by the contact rollers 353 and cleaning by the scrapers 352, the pulp residue adhering to the side surfaces of the conveyor belt is cleaned in an all-round and thorough manner, avoiding problems such as conveyor deviation and residual contamination of subsequent pulp caused by pulp adhesion and accumulation. When the contact pressure between the scraper 352 and the conveyor belt exceeds the preset threshold, the scraper 352 will drive the contact frame 351 to move downward along the slide bar 355, and simultaneously squeeze the second spring 356 sleeved on the slide bar 355. The excess pressure is absorbed by the elastic deformation of the spring, and the adhesion force between the scraper 352 and the conveyor belt is automatically adjusted. To avoid mechanical damage such as wear and scratches on the side of the conveyor belt due to excessive pressure, thus extending the service life of the conveyor belt; at the same time, to ensure that the scraper 352 always adheres to the conveyor surface with reasonable pressure, so as to ensure that the cleaning effect is not reduced and to prevent equipment vibration caused by rigid contact, thereby improving the stability of the cleaning process. After the suction machine 33 is turned on, the negative pressure suction it generates will quickly capture the pulp debris that falls off the side of the conveyor belt when the scraper 352 and the contact roller 353 are cleaning it. Under the suction force, the debris moves downward through the filter plate 354 and finally falls onto the wire mesh plate 32 for centralized collection. This avoids debris flying and polluting the production environment, and prevents debris from adhering to the conveyor belt or mixing into subsequent pulp. This ensures the hygiene of the production environment and improves the purity of the pulp. At the same time, the suction generated by the suction machine 33 will drive the fan blades at the bottom of the rotating shaft 341 to rotate, and the fan blades will further drive the rotating shaft 341 to rotate synchronously on the top of the mesh plate 32. The rotating shaft 341 rotates in a close-fitting manner with the top of the screen plate 32 and the bottom of the filter plate 354 through the rotating housings 342 on both sides, thereby driving the cleaning rollers 343 on the rotating housings 342 to roll and clean the top of the screen plate 32 and the bottom of the filter plate 354. Remove pulp debris adhering to the mesh in a timely manner to prevent the mesh plate 32 and filter plate 354 from clogging, ensure smooth ventilation channels, and ensure that the suction machine 33 continuously and stably generates negative pressure suction to avoid a decrease in collection efficiency due to clogging. As the cleaning roller 343 rotates inside the rotating housing 342, it will continuously contact and rub against the stop block 344 inside the housing. The stop block 344 can scrape off the pulp debris that accumulates on the rotating shaft 341, preventing the debris from accumulating and clumping on the rotating shaft 341, thus preventing it from interfering with the normal rotation and cleaning action of the cleaning roller 343 and ensuring the long-term stable operation of the cleaning mechanism.
