Description

Technical Field

[0001] This utility model relates to the technical field of edge suction mechanism for papermaking equipment, specifically a three-way adjustable edge suction mechanism for papermaking equipment. Background Technology

[0002] Papermaking is divided into two forms: machine-made and manual. Machine-made papermaking is carried out continuously on a paper machine. Pulp suitable for paper quality is diluted with water to a certain concentration, and then initially dewatered on the wire section of the paper machine to form a wet sheet. After pressing and dewatering, it is dried into paper. The main steps are pulping, conditioning, papermaking, and processing.

[0003] As paper machine speeds increase, the edge of the paper after the full-width paper has been edge-trimmed by the wire section's edge-trimming water needles often fails to follow the wire movement into the wire section's dead roll waste pool due to the combined effects of centrifugal force and negative pressure from the high-speed rotating suction rollers. Instead, it enters the press section's press zone. Since the paper edge is easily squeezed to form pulp clumps, its entry into the press zone at this time can cause harmful damage to the surface of the high-linear-pressure press rolls, resulting in significant losses and seriously affecting the operation of the paper machine. The research on three-way adjustable edge suction boxes aims to improve the safety of paper machine operation, indirectly improve the stability of paper machine operation, reduce production costs, and reduce equipment energy consumption, which has far-reaching significance. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a three-way adjustable edge suction mechanism for papermaking equipment, thereby solving the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-way adjustable edge suction mechanism for papermaking equipment, comprising a paper feeding assembly, an edge suction adjustment assembly, and special paper, wherein the paper feeding assembly includes a mounting bracket, and the outer wall of the mounting bracket is rotatably connected to a drive roller, a vacuum suction roller, and a vacuum flat roller; The edge suction adjustment assembly includes a fixed bracket, an edge suction panel on top of the fixed bracket, and a vacuum chamber connected to the inner wall of the edge suction panel. An angle adjustment bolt and a vertical mesh direction adjustment bolt are respectively provided on the top of the fixed bracket. A rotating plate is rotatably connected to one end of the angle adjustment bolt near the fixed bracket. A limit rod is fixedly mounted on the top of the rotating plate. A self-buffering spring is provided above the limit rod. An air suction pipe passes through the outer wall of the vacuum chamber. A horizontal adjustment bolt is provided on the outer wall of the air suction pipe. A movable groove is opened on the outer wall of the fixed bracket.

[0006] Through the above technical solution, the structure of the paper feeding assembly, edge suction adjustment assembly, fixed bracket, edge suction panel, vacuum chamber, angle adjustment bolts, self-buffering spring, lateral adjustment bolts, and vertical wire mesh direction adjustment bolts allows the user to attach the edge suction panel to the edge of the specialty paper after installation. This provides continuous tension and prevents deviation, curling, or wrinkling during operation, ensuring the smooth conveying and processing of the specialty paper. It also assists in the smooth transition of the paper web and adapts to the speed differences of different processes such as the wire section, pressing section, and drying section, thereby improving the production quality and efficiency of the papermaking equipment for specialty paper. The vacuum chamber is connected to the edge suction panel and is connected to a vacuum pump through a suction pipe to form a stable negative pressure zone. The negative pressure value can be adjusted by the operating frequency of the vacuum pump to adapt to different paper types.

[0007] Preferably, the top of the fixed bracket is slidably connected to a movable seat, and the top of the fixed bracket is fixedly fitted with a limiting plate. The outer wall of the limiting plate has a through hole, and the inner wall of the through hole is threadedly connected to the outer wall of the vertical mesh direction adjusting bolt.

[0008] Through the above technical solution, by setting through holes and vertical mesh direction adjustment bolt structure, the user can make the moving seat slide along the top of the fixed bracket by rotating the vertical mesh direction adjustment bolt during operation. This makes it easy for the user to adjust the position of the suction panel, achieve the effect of vertical adjustment of the suction panel position, ensure that the suction panel can fit the periphery of the special paper, so that both sides of the special paper can be adsorbed, thereby improving the adsorption effect of the suction mechanism on the special paper.

[0009] Preferably, the end of the vertical mesh direction adjusting bolt away from the limiting plate is rotatably connected to the outer wall of the movable seat, and a fixed shell is fixedly assembled on the top of the movable seat.

[0010] Through the above technical solution, by setting the vertical mesh direction adjustment bolt and the fixed shell structure, when the user rotates the vertical mesh direction adjustment bolt, it will drive the fixed shell to move, thereby adjusting the adhesion between the suction edge panel and the special paper. This makes it easy for the user to adjust the adhesion between the suction edge panel and the special paper, thus achieving the effect of adjustable adhesion tightness of the mechanism.

[0011] Preferably, the top of the fixed shell has a limiting hole, and the inner wall of the limiting hole is threadedly connected to the outer wall of the angle adjusting bolt, and the outer wall of the rotating plate is rotatably connected to the inner wall of the fixed shell.

[0012] Through the above technical solution, by setting an angle adjustment bolt structure, when the user rotates the angle adjustment bolt during operation, the end of the angle adjustment bolt near the fixed shell will move towards the rotating plate, thereby allowing the angle adjustment bolt to squeeze the rotating plate and cause the rotating plate to rotate along the inner wall of the fixed shell, achieving the effect of adjusting the suction angle of the suction panel, thus facilitating user operation and improving the flexibility of the mechanism.

[0013] Preferably, the outer wall of the rotating plate has a circular hole, and the inner wall of the circular hole is threadedly connected to the outer wall of the transverse adjusting bolt. The outer wall of the suction pipe is fixedly fitted with a connecting shell, and the inner wall of the connecting shell is rotatably connected to the outer wall of the transverse adjusting bolt.

[0014] Through the above technical solution, by setting the connecting shell and the horizontal adjustment bolt structure, the user can rotate the horizontal adjustment bolt during operation to move the connecting shell and the suction pipe, thereby achieving the effect of horizontally adjusting the position of the suction edge panel, and thus realizing the three-way adjustment function of the mechanism.

[0015] Preferably, the outer wall of the suction panel is attached to the outer wall of the special paper, the inner wall of the self-buffering spring is sleeved with a round rod, and the outer wall of the round rod is slidably connected to the inner wall of the fixed shell, and the inner wall of the movable groove is threaded with an adjustment bolt parallel to the mesh direction.

[0016] Through the above technical solution, by setting a self-buffered spring and a round rod structure, when the angle adjustment bolt is raised during operation, the rotating plate will squeeze the round rod, causing the round rod to compress the self-buffered spring. Conversely, the round rod will return to its original position due to the decrease in the elasticity of the self-buffered spring. This makes it easy for the user to repeatedly adjust the angle of the suction panel, thereby ensuring that the subsequent use of the mechanism will not be affected.

[0017] Compared with the prior art, this utility model provides a three-way adjustable edge suction mechanism for papermaking equipment, which has the following beneficial effects: 1. This three-way adjustable edge suction mechanism for papermaking equipment, through the setting of paper feeding assembly, mounting bracket, drive roller, vacuum suction roller, vacuum flat roller, edge suction panel, and suction pipe structure, enables the edge suction structure to use the edge suction panel to suction the sides of the special paper during operation, thereby effectively preventing the special paper from forming wrinkles or even bending during transportation or processing, thus improving the production quality and efficiency of special paper by the papermaking equipment.

[0018] 2. This three-way adjustable edge suction mechanism for papermaking equipment, through its rotating plate, limiting rod, horizontal adjusting bolt, and vertical wire mesh direction adjusting bolt structure, allows the user to adjust the position of the suction panel by rotating the horizontal adjusting bolt during use, thereby achieving the effect of horizontal adjustment of the suction panel. Furthermore, the user can adjust the vertical wire mesh direction adjusting bolt and the angle adjusting bolt to achieve the effects of vertical and angle adjustment of the suction panel, respectively. This facilitates user operation and improves the flexibility and adaptability of the mechanism. Attached Figure Description

[0022] like Figure 1-4 As shown, the present invention provides a three-way adjustable edge suction mechanism for papermaking equipment, including a paper feeding assembly 1, an edge suction adjustment assembly 2, and special paper 3.

A horizontal adjustment bolt 206 is provided on the outer wall of the air suction pipe 211. A movable groove 208 is opened on the outer wall of the fixed bracket 201.

[0023] The advantages are that, through the structure of the paper feeding assembly 1, the edge suction adjustment assembly 2, the fixed bracket 201, the edge suction panel 202, the vacuum chamber 203, the angle adjustment bolt 204, the self-buffering spring 205, the transverse adjustment bolt 206, and the vertical wire mesh direction adjustment bolt 207, after installation, the user can use the edge suction panel 202 to adhere to the edge of the special paper 3, providing continuous tension and avoiding deviation, curling, or wrinkling during operation. This ensures that the special paper 3 is always transported and processed smoothly, and also assists in the smooth transition of the paper web, adapting to the speed differences of different processes such as the wire section, pressing section, and drying section, thereby improving the production quality and efficiency of the papermaking equipment for the special paper 3. The vacuum chamber 203 is connected to the edge suction panel 202 and is connected to the vacuum pump through the suction pipe 211 to form a stable negative pressure zone. The negative pressure value can be adjusted by the operating frequency of the vacuum pump to adapt to different paper types.

[0024] Specifically: The top of the fixed bracket 201 is slidably connected to a movable seat, and the top of the fixed bracket 201 is fixedly equipped with a limiting plate. The outer wall of the limiting plate has a through hole, and the inner wall of the through hole is threadedly connected to the outer wall of the vertical mesh direction adjusting bolt 207.

[0025] The advantage is that, through the through hole and the vertical mesh direction adjustment bolt 207 structure, the user can rotate the vertical mesh direction adjustment bolt 207 during operation to make the movable seat slide along the top of the fixed bracket 201, thereby facilitating the user to adjust the position of the suction panel 202 and achieving the effect of vertical adjustment of the suction panel 202. This ensures that the suction panel 202 can fit against the periphery of the special paper 3, so that both sides of the special paper 3 can be adsorbed, thereby improving the adsorption effect of the suction mechanism on the special paper 3.

[0026] Specifically: the end of the vertical mesh direction adjusting bolt 207 away from the limiting plate is rotatably connected to the outer wall of the moving seat, and the top of the moving seat is fixedly equipped with a fixed shell.

[0027] The advantage is that, through the vertical mesh direction adjustment bolt 207 and the fixed shell structure, when the user rotates the vertical mesh direction adjustment bolt 207, it will drive the fixed shell to move, thereby adjusting the adhesion between the suction panel 202 and the special paper 3. This makes it easy for the user to adjust the adhesion between the suction panel 202 and the special paper 3, thus achieving the effect of adjustable adhesion tightness of the mechanism.

[0028] Specifically: a limiting hole is provided at the top of the fixed shell, and the inner wall of the limiting hole is threadedly connected to the outer wall of the angle adjusting bolt 204, and the outer wall of the rotating plate 209 is rotatably connected to the inner wall of the fixed shell.

[0029] The advantage is that, through the setting of the angle adjustment bolt 204 structure, when the user rotates the angle adjustment bolt 204 during operation, the end of the angle adjustment bolt 204 near the fixed shell will move towards the rotating plate 209, thereby allowing the angle adjustment bolt 204 to press the rotating plate 209, causing the rotating plate 209 to rotate along the inner wall of the fixed shell, thus achieving the effect of adjusting the adsorption angle of the suction panel 202, which facilitates user operation and improves the flexibility of the mechanism.

[0030] Specifically: the outer wall of the rotating plate 209 has a circular hole, and the inner wall of the circular hole is threadedly connected to the outer wall of the transverse adjusting bolt 206. The outer wall of the suction pipe 211 is fixedly fitted with a connecting shell, and the inner wall of the connecting shell is rotatably connected to the outer wall of the transverse adjusting bolt 206.

[0031] The advantage is that, through the structure of the connecting shell and the lateral adjustment bolt 206, the user can rotate the lateral adjustment bolt 206 during operation to move the connecting shell and the suction pipe 211, thereby achieving the effect of lateral adjustment of the position of the suction edge panel 202, and thus realizing the three-way adjustment function of the mechanism.

[0032] Specifically: the outer wall of the suction panel 202 is attached to the outer wall of the special paper 3, the inner wall of the self-buffering spring 205 is fitted with a round rod, and the outer wall of the round rod is slidably connected to the inner wall of the fixed shell, and the inner wall of the movable groove 208 is threaded with a parallel mesh direction adjustment bolt.

[0033] The advantage is that, through the self-buffered spring 205 and the round rod structure, when the angle adjusting bolt 204 is raised during operation, the rotating plate 209 will squeeze the round rod, causing the round rod to compress the self-buffered spring 205. Conversely, the round rod will return to its original position due to the decrease in elasticity of the self-buffered spring 205. This makes it easy for the user to repeatedly adjust the angle of the suction panel 202, thus ensuring that the subsequent use of the mechanism will not be affected.

[0034] Working principle: After installing the mechanism, the user can first attach the suction panel 202 to the special paper 3 so that the edges of both sides of the special paper 3 can be attracted by the suction panel 202, thereby reducing the probability of wrinkles or deviation of the special paper 3 during the conveying process, thus improving the production efficiency and quality of the special paper 3 of the papermaking equipment. During operation, the user can also adjust the angle, lateral position and longitudinal position of the suction panel 202 by rotating the lateral adjustment bolt 206, the angle adjustment bolt 204 and the vertical wire direction adjustment bolt 207, respectively, so as to achieve the effect of effectively adsorbing the special paper 3, thereby improving the adaptability and flexibility of the mechanism.
