Abstract
Description
Technical Field
[0001] This invention relates to the field of cylindrical mirror grinding technology, specifically a paper forming device that can adjust fiber distribution. Background Technology
[0002] In papermaking, wet-end forming is the core process that determines the physical properties and uniformity of paper. Key indicators such as paper strength, air permeability, smoothness, and printability largely depend on the uniformity and orientation of fiber distribution on the forming wire.
[0003] The existing technology has the following prominent problems: First, in the fiber dispersion stage within the headbox, conventional stirring devices mostly use axial propellers or simple impellers, which have limited shearing and dispersion capabilities for high-concentration pulp, making it difficult to effectively break down the fibers. These insufficiently dissociated fiber clumps directly lead to uneven pulp concentration, resulting in defects on the forming wire and severely affecting the basis weight uniformity of the paper. Second, in the critical transfer stage from the headbox to the forming wire, the existing technology lacks a secondary uniform distribution of the dispersed fibers. The pulp falls freely under gravity and inertia, and the fibers easily re-agglomerate and deposit in a disordered state on the wire surface, making it impossible to effectively control the fiber orientation and easily leading to uneven fiber distribution in the formed paper.
[0004] Furthermore, existing forming equipment lacks sufficient ability to homogenize the slurry layer. Although some equipment is equipped with simple vibrators or leveling rollers, their operating modes are singular and their parameters are fixed. For example, vibration only provides a single frequency excitation in the vertical direction, and cannot adjust the vibration mode according to different slurry characteristics, resulting in unstable homogenization effects. In addition, the lack of a surface combing mechanism that works in conjunction with vibration cannot effectively eliminate any jetting streaks or turbulence marks that may exist on the surface of the slurry just exiting the weir, thus creating a bottleneck in improving the uniformity of fiber distribution.
[0005] Therefore, there is an urgent need in the field for a forming device that can solve the problems of insufficient mixing inside the headbox and uneven fiber distribution during the forming process, and can produce high-quality paper with highly uniform fiber distribution. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When the pulp is conveyed to the forming table, it first accumulates in the brush plate. The distribution of pulp fibers can be detected by the vision sensor on the top of the brush plate, thereby adjusting the vibration frequency of the vibrating motor on the movable seat to adjust the distribution of pulp fibers until the fiber distribution is uniform. Then, the movable seat is moved along the direction of the forming table by the lead screw motor. The pulp passes through the brush bristles to make the surface smoother and make the pulp evenly spread on the forming table. 2. When the pulp is in the headbox, driven by the agitation assembly, the agitator rod rotates on its own axis and also revolves around the drive gear and driven gear, so that the agitator rod can move to various parts of the headbox. The agitator rod is equipped with multiple agitator blades to ensure that the agitator rod can fully agitate the pulp in the headbox and make the fibers in the pulp evenly distributed. 3. While the stirring rod is driven by the stirring component to stir the pulp, it also drives the cleaning component to move synchronously. The scraper on the cleaning component can scrape off the pulp adhering to the inner wall of the headbox, preventing the pulp from sticking to the inner wall and affecting the output, thereby improving the utilization rate of the pulp.

Detailed Implementation
[0019] 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.
[0020] Example: Figures 1-7As shown, the present invention provides a technical solution for a paper forming device with adjustable fiber distribution. The device includes a base 1, a forming platform 2 mounted on the base 1, a baffle plate 3 movably connected to the forming platform 2, a vision sensor 4 mounted on the baffle plate 3, a headbox 5 fixedly mounted on the base 1, a stirring assembly 6 inside the headbox 5, and a cleaning component 7 on the inner wall of the headbox 5. Before pulp forming, pulp raw materials need to be added to the headbox 5. Pulp with incompletely separated fibers is poured into the headbox 5 through the feed inlet 53, and then the drive is activated. The drive motor 61 drives the driving gear 62 to rotate synchronously. Since the driving gear 62 is coaxially arranged with the rotating plate 63, the rotating plate 63 also rotates accordingly. Because the driving gear 62 meshes with the first planetary gear 6302, all the first planetary gears 6302 mounted on the connecting plate 6301 will revolve around the driving gear 62. Since the first planetary gear 6302 is coaxially arranged with the second planetary gear 6303, the second planetary gear 6303 also rotates accordingly, thereby driving the driven gear 6401, which meshes with it, to rotate. The connecting plate 63... 01 is connected to the adapter plate 64, which is equipped with a stirring rod 65. When the drive motor 61 starts, through a series of transmissions by the stirring assembly 6, the adapter plate 64 will revolve around the driving gear 62. Specifically, the driven gear 6401 at one end of the adapter plate 64 always revolves around the driving gear 62. While the driven gear 6401 revolves, it also rotates on its own axis due to meshing with the second planetary gear 6303, thus causing the entire adapter plate 64 to rotate around the center of the driven gear 6401. This, in turn, causes the other end of the adapter plate 64 to rotate. The stirring rod 65 revolves around the driven gear 6401, and a rotating motor 66 is provided at the top of the stirring rod 65. The rotating motor 66 enables the stirring rod 65 to rotate. Through this series of transmissions, the stirring rod 65 can be moved to any position in the headbox 5. The stirring rod 65 is long enough to extend to the bottom of the headbox 5. Multiple stirring blades 6501 can be installed on the stirring rod 65. Ultimately, it can be ensured that the stirring rod 65, in motion, thoroughly and fully stirs the pulp in the headbox 5, completely breaking down and dispersing the fibers in the pulp evenly.The evenly dispersed pulp is then discharged through the discharge pipe 52 and falls onto the forming table 2. Due to the restriction of the baffle plate 3, the pulp is initially confined inside the brush plate 33. First, the pulp is detected by the vision sensor 4 to observe whether it is evenly spread on the forming table 2. If not, the vibration motor 34 can be activated. Through the vibration of the vibration motors 34 on both sides of the movable seat 31, the pulp inside the brush plate 33 can gradually become flat, ensuring a consistent thickness. Then, the pulp inside the brush plate 33 needs to be directly exposed onto the forming table 2 to complete the subsequent steps. During pulp forming, the lead screw 22 is rotated by the lead screw motor 21, which in turn moves the connecting part 3101 sleeved on the lead screw 22 along the forming table 2. The positioning rods 23 on both sides of the lead screw 22 limit the movement of the connecting part 3101, preventing wobbling or directional deviation during movement. As the movable seat 31 moves, the pulp located in the brush plate 33 is transferred to the forming table 2. During this transfer, the pulp passes through the brush bristles 3301, which smooth out wrinkles on the pulp surface, ensuring a smooth pulp surface.
[0021] A bracket 11 is installed on the base 1, and a positioning frame 1101 is provided on the top of the bracket 11. The base 1 supports the entire equipment, the bracket 11 can fix the headbox 5, and the positioning frame 1101 on the bracket 11 can ensure the stability of the headbox 5 and prevent it from shaking due to the vibration motor 34.
[0022] A lead screw motor 21 is installed at one end of the forming table 2. The output end of the lead screw motor 21 is connected to the lead screw 22. The lead screw 22 connects the two ends of the forming table 2. Positioning rods 23 are provided on both sides of the lead screw 22.
[0023] The baffle plate 3 includes a movable seat 31 surrounding the outside of the forming table 2. A connecting part 3101 is provided at the bottom of the movable seat 31, which is connected to both the lead screw 22 and the positioning rod 23. A positioning hole 32 is provided at the top of the movable seat 31. A brush plate 33 is installed inside the movable seat 31, with a certain distance between the brush plate 33 and the surface of the forming table 2. Brush bristles 3301 are provided on both sides of the brush plate 33. A vision sensor 4 is installed inside the brush plate 33. Vibration motors 34 are fixedly installed on both sides of the movable seat 31. The evenly dispersed pulp is discharged through the discharge pipe 52 and falls onto the forming table 2. Due to the restriction of the baffle plate 3, the pulp is initially confined inside the brush plate 33. The vision sensor 4 first detects the pulp to observe whether it is evenly spread on the forming table 2. If not, vibration can be activated. The vibration of the motor 34 on both sides of the movable seat 31 gradually flattens the pulp inside the brush plate 33, ensuring a consistent thickness. Then, the pulp inside the brush plate 33 needs to be directly exposed on the forming table 2 to complete the subsequent pulp forming. At this time, the lead screw motor 21 drives the lead screw 22 to rotate, which drives the connecting part 3101 sleeved on the lead screw 22 to move along the direction of the forming table 2. The positioning rods 23 on both sides of the lead screw 22 can limit the movement of the connecting part 3101 to prevent shaking or directional deviation during the movement. As the movable seat 31 moves, the pulp inside the brush plate 33 is transferred to the forming table 2. During the pulp transfer, it passes through the brush bristles 3301. The brush bristles 3301 can smooth the wrinkles on the surface of the pulp to ensure the smoothness of the pulp.
[0024] The headbox 5 is installed inside the positioning frame 1101. A conical platform 51 is provided at the bottom of the headbox 5. A discharge pipe 52 is installed at the lowest point of the conical platform 51. A feed inlet 53 is provided on one side of the headbox 5.
[0025] The mixing assembly 6 includes a drive motor 61 fixedly installed on the top of the headbox 5. The output end of the drive motor 61 is connected to a drive gear 62. The drive gear 62 is installed on the top inside the headbox 5. A rotating plate 63 is installed below the drive gear 62. The rotating plate 63 is coaxially arranged with the drive gear 62. Several connecting plates 6301 are arranged on the outside of the rotating plate 63. A first planetary gear 6302 is arranged on the top of the connecting plate 6301, and a second planetary gear 6303 is installed on the bottom of the connecting plate 6301.
[0026] The end of the connecting plate 6301 is connected to the adapter plate 64. A driven gear 6401 is installed at the connection between the connecting plate 6301 and the adapter plate 64. The second planetary gear 6303 is meshed with the driven gear 6401. The other end of the adapter plate 64 is equipped with a stirring rod 65. A rotating motor 66 is installed on the top of the stirring rod 65. Several stirring blades 6501 are evenly arranged on the stirring rod 65.
[0027] A ring gear 67 is coaxially arranged on the outside of the drive gear 62. The ring gear 67 is fixed to the top inside the headbox 5 and meshes with the first planetary gear 6302.
[0028] The cleaning component 7 includes several connecting plates 71 connected to the outer side of the ring gear 67. The connecting plates 71 are fixedly connected to the scraper 72, which is in close contact with the inner wall of the headstock box 5. Inclined surfaces 7201 are provided on both sides of the scraper 72. During the operation of the mixing assembly 6, the first planetary gear 6302 revolves around the driving gear 62. During this revolution, the ring gear 67 meshes with it and rotates. The outer side of the ring gear 67 is connected to the cleaning component 7. Therefore, the operation of the mixing assembly 6 causes the cleaning component 7 to move synchronously. The connection between the ring gear 67 and the cleaning component 7 is achieved through the connecting plates 71. The connecting plates 71 do not interact with the headstock box 5. The inner wall of the headbox 5 is not tightly attached, but a gap is left so that the scraper 72 at the end of the connecting plate 71 will be tightly attached to the inner wall of the headbox 5. This is to prevent the cleaning component 7 from blocking the feed port 53 during operation, thus avoiding untimely pulp supply. The scraper 72, which is tightly attached to the inner wall of the headbox 5 and rotates along the inner wall, can scrape off the pulp adhering to the inner wall. In order to improve the cleaning efficiency of the scraper 72, inclined surfaces 7201 are provided on both sides of the scraper 72. The bottom of the headbox 5 has a conical truncated platform 51 structure, which can spontaneously allow the pulp to flow out. This also prevents the pulp from accumulating in the headbox 5, reduces pulp loss, and improves pulp utilization.
[0029] Working principle of the invention: Before pulp forming, pulp raw materials need to be added to the headbox 5. Pulp with incomplete fiber separation is poured into the headbox 5 through the feed port 53. Then, the drive motor 61 is turned on, which drives the drive gear 62 to rotate synchronously. Since the drive gear 62 is coaxial with the rotating plate 63, the rotating plate 63 also rotates. Because the drive gear 62 meshes with the first planetary gear 6302, all the first planetary gears 6302 installed on the connecting plate 6301 will revolve around the drive gear 62. The first planetary gear 6302 is coaxial with the second planetary gear 6303, so the second planetary gear 6303 also rotates, thereby driving the driven gear 6401 that meshes with it to rotate. The connecting plate 6301 is connected to the adapter plate 64, which is equipped with a stirring rod 65. Therefore, when the drive motor 61 is started, through a series of transmissions of the stirring assembly 6, the adapter plate 64 will revolve around the drive gear 6302. 2. The driven gear 6401 at one end of the adapter plate 64 revolves around the driving gear 62. While the driven gear 6401 revolves, it also rotates due to its meshing with the second planetary gear 6303, which in turn drives the entire adapter plate 64 to rotate around the center of the driven gear 6401. This causes the stirring rod 65 connected to the other end of the adapter plate 64 to revolve around the driven gear 6401. The top of the stirring rod 65 is equipped with a rotating motor 66, which enables the stirring rod 65 to rotate. Through this series of transmissions, the stirring rod 65 can be moved to any position within the headbox 5. The stirring rod 65 is long enough to extend to the bottom of the headbox 5. Multiple stirring blades 6501 can be installed on the stirring rod 65, ultimately ensuring that the stirring rod 65, while in motion, thoroughly and completely stirs the pulp in the headbox 5, thoroughly breaking up and dispersing the fibers in the pulp evenly.
[0030] The evenly dispersed pulp is then discharged through the discharge pipe 52 and falls onto the forming table 2. Due to the restriction of the baffle plate 3, the pulp is initially confined inside the brush plate 33. First, the pulp is detected by the vision sensor 4 to observe whether it is evenly spread on the forming table 2. If not, the vibration motor 34 can be activated. Through the vibration of the vibration motors 34 on both sides of the movable seat 31, the pulp inside the brush plate 33 can gradually become flat, ensuring a consistent thickness. Then, the pulp inside the brush plate 33 needs to be directly exposed onto the forming table 2 to complete the subsequent steps. During pulp forming, the lead screw motor 21 drives the lead screw 22 to rotate, which in turn drives the connecting part 3101 sleeved on the lead screw 22 to move along the direction of the forming table 2. The positioning rods 23 on both sides of the lead screw 22 can limit the movement of the connecting part 3101 to prevent shaking or directional deviation during the movement. As the movable seat 31 moves, the pulp located in the brush plate 33 is transferred to the forming table 2. During the pulp transfer, it passes through the brush bristles 3301. The brush bristles 3301 can smooth out the wrinkles on the surface of the pulp and ensure the smoothness of the pulp.
[0031] During the operation of the mixing assembly 6, the first planetary gear 6302 revolves around the driving gear 62. This revolution drives the meshing ring gear 67 to rotate. The outer side of the ring gear 67 is connected to the cleaning component 7. Therefore, the operation of the mixing assembly 6 causes the cleaning component 7 to move synchronously. The connection between the ring gear 67 and the cleaning component 7 is achieved through a connecting plate 71. The connecting plate 71 is not tightly fitted against the inner wall of the runner box 5; instead, a gap is left. The scraper 72 at the end of the connecting plate 71 will then be tightly fitted. The scraper 72 is attached to the inner wall of the headbox 5. This is to prevent the cleaning component 7 from blocking the feed inlet 53 during operation, thus avoiding a situation where the pulp supply is not timely. The scraper 72, which is closely attached to the inner wall of the headbox 5 and rotates along the inner wall, can scrape off the pulp adhering to the inner wall. In order to improve the cleaning efficiency of the scraper 72, inclined surfaces 7201 are also provided on both sides of the scraper 72. The bottom of the headbox 5 has a conical truncated platform 51 structure, which can spontaneously allow the pulp to flow out. This also prevents the pulp from accumulating in the headbox 5, reduces pulp loss, and improves the utilization rate of pulp.
[0032] When the pulp is conveyed to the forming table 2, it first accumulates in the brush plate 33. The visual sensor 4 on the top of the brush plate 33 can detect the distribution of pulp fibers, thereby adjusting the vibration frequency of the vibration motor 34 on the movable seat 31 to adjust the distribution of pulp fibers until the fiber distribution is uniform. Then, the movable seat 31 is moved along the direction of the forming table 2 by the lead screw motor 21. The pulp passes through the brush bristles 3301 to make the surface smoother and make the pulp evenly spread on the forming table 2. When the pulp is in the headbox 5, driven by the agitation assembly 6, the agitation rod 65 rotates on its own axis and revolves around the drive gear 62 and the driven gear 6401, so that the agitation rod 65 can move to various parts of the headbox 5. The agitation rod 65 is equipped with multiple agitation blades 6501 to ensure that the agitation rod 65 can fully agitate the pulp in the headbox 5 and make the fiber distribution in the pulp uniform. While the stirring component 6 drives the stirring rod 65 to stir the pulp, it also drives the cleaning component 7 to move synchronously. The scraper 72 on the cleaning component 7 can scrape off the pulp adhering to the inner wall of the headbox 5, preventing the pulp from sticking to the inner wall and affecting the output, thereby improving the utilization rate of the pulp.
