Description

Technical Field

[0001] This utility model belongs to the technical field of paper sizing and coating equipment, and particularly relates to a glue filtration device for paper sizing and coating processing. Background Technology

[0002] In the sizing and coating process of papermaking, paper sheets are transferred via rollers coated with adhesive to ensure even adhesion of the adhesive to the paper surface, thereby improving key properties such as water resistance and strength. Because the axial length of the rollers must be greater than the width of the paper sheet (to ensure full contact between the paper sheet and the rollers), excess adhesive remains on the edges of the rollers. This excess adhesive is prone to splashing during high-speed rotation of the rollers. This can lead to adhesive accumulation or gaps at the paper edges, resulting in uneven sizing and affecting product quality. Furthermore, the splashed adhesive may adhere to transmission components or the paper transport path, causing paper breakage and severely impacting the continuity of papermaking, increasing downtime and raw material waste. Therefore, in the existing paper sizing and coating process, excess glue needs to be removed in a timely manner to achieve collection and filtration, so that resources can be recycled and reused. However, the glue residue on both sides of the glue roller is difficult to completely detach from the roller, resulting in poor collection efficiency and insufficient collection. Furthermore, in the glue treatment process, the collection and filtration processes are separated, which requires a long processing time, thereby affecting the filtration and recovery efficiency of the glue and thus affecting the efficiency of glue treatment. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a glue filtration device for paper sizing and coating processes. Through the cooperation of an adjustable rubber scraper, a collection iron box, and a filter box, it can effectively scrape off and quickly collect residual glue from the edges, achieving integrated glue collection and filtration, thus improving processing efficiency. This solves the problems in the prior art where residual glue on both sides of the glue roller is difficult to remove completely, resulting in poor collection efficiency and insufficient collection. Furthermore, in the glue processing flow, the collection and filtration processes are separate, requiring a long processing time, which in turn affects the glue filtration and recovery efficiency, thereby impacting the overall efficiency of glue processing.

[0004] This utility model is implemented as follows: a glue filtration device for paper sizing and coating processes includes a glue roller body and a fixed base. Shafts are fixedly connected to both ends of the glue roller body, and fixed plates are fixedly connected to both ends of the top of the fixed base. The shafts are connected to the corresponding fixed plates via bearings. A motor is fixedly installed on the outer wall of the fixed plate, and the output end of the motor is fixedly connected to the shaft. Scraping and collecting components are provided on both sides of the glue roller body's edges. Filter boxes are installed on both sides of the outer wall of the fixed base. The scraping and collecting components include a collecting iron box, an adjusting support plate, and a support frame. A rubber scraper is fixedly connected to the top outer wall of the collecting iron box. The bottom side wall of the collecting iron box is connected and fixed to the filter box via a glue discharge pipe. The front of the collecting iron box is fixedly connected to the upper end of the adjusting support plate by bolts, and the lower end of the adjusting support plate is rotatably mounted on the support frame.

[0005] In a preferred embodiment of this utility model, one end of the support frame is fixed to the fixed base by bolts, and the inner side of the other end of the support frame is connected to a rotating rod by a bearing. The lower end of the adjusting support plate is sleeved and fixed on the rotating rod, and the discharge tube is a flexible hose.

[0006] This design allows for two main benefits. First, the rotation of the rotating rod and the adjusting support plate enables the collection box to rotate around the rod, flexibly adjusting the contact angle and pressure between the rubber scraper and the rubber roller body. This ensures the rubber scraper is tightly attached to the surface of the rubber roller, effectively scraping away residual adhesive from the edges and solving the problem of insufficient adhesive collection. Second, the flexible hose-like discharge pipe can be flexibly deformed according to the angle of the collection box, achieving stable connection between the collection box and the filter box. This provides a guarantee for the integrated transmission of adhesive from collection to filtration, reducing process connection time.

[0007] As a preferred embodiment of this utility model, a vertical plate is fixedly connected to the outside of the side wall of the support frame. The vertical plate is arranged in an L-shape. A locking screw is threaded through the end of the vertical plate. A threaded hole is opened in the middle of one end of the rotating rod. The threaded hole and the locking screw are threadedly connected.

[0008] With this setting, after adjusting the angle of the collection box, tightening the locking screw to lock it into the threaded hole of the rotating rod can fix the position of the rotating rod and the adjusting support plate, preventing the adjusting support plate from shifting due to vibration during the rotation of the rubber roller, and ensuring that the rubber scraper always maintains a stable scraping state.

[0009] As a preferred embodiment of this utility model, the inside of the collecting iron box is provided with a liquid collection cavity, and a uniformly distributed liquid collection channel is provided between the rubber scraper and the top surface of the collecting iron box. The liquid collection cavity, the liquid collection channel and the discharge pipe are connected. The rubber scraper is provided with an arc-shaped inclined structure to facilitate contact with the outer surface of the rubber roller body.

[0010] This design allows the rubber scraper to fit the outer circumference of the rubber roller body, increasing the scraping contact area and thoroughly scraping off residual adhesive from the edge of the roller. The scraped adhesive can then quickly flow into the collection chamber of the collection box through the collection channel. The interconnected design of the collection chamber, collection channel, and discharge pipe allows the adhesive in the collection chamber to be promptly transported to the filter box through the discharge pipe, achieving a seamless connection between adhesive collection and filtration, reducing the residence time of adhesive in the collection process, and improving overall processing efficiency.

[0011] As a preferred embodiment of this utility model, a coarse filter screen and a fine filter screen are slidably inserted into the interior of the filter box from top to bottom, a door panel is hinged to the front of the filter box, and a glue outlet tube is fixedly connected to the bottom side wall of the filter box.

[0012] This setup allows the coarse filter to remove larger particles of paper fibers and glue lumps from the adhesive solution, while the fine filter further filters out smaller impurities. This two-stage filtration significantly improves the purity of the adhesive solution. The sliding plug-in installation method facilitates the periodic removal of the filter screen for cleaning or replacement, preventing clogging. The door panel allows operators to easily open the filter box to check the filter screen's condition, providing ample operating space. The dispensing hose allows the filtered pure adhesive solution to be directly discharged to a storage container or reused in the adhesive application system, achieving resource recycling.

[0013] As a preferred embodiment of this utility model, both inner walls of the filter box are fixedly connected with supporting slide rails, and the coarse filter screen and the fine filter screen are slidably inserted between the corresponding supporting slide rails.

[0014] This design provides stable sliding support for both the coarse and fine filters, making installation and removal convenient.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: more complete collection of adhesive liquid: the adjustable rubber scraper can closely fit the rubber roller, and cooperate with the liquid collection channel and liquid collection chamber to fully scrape off and quickly collect residual adhesive liquid at the edge, thus solving the problem of insufficient collection; Achieve integrated collection and filtration: The discharge pipe connects the collection iron box and the filter box, reducing the time between processes, avoiding glue transfer loss, and improving processing efficiency; High filtration efficiency and practicality: The two-stage filter significantly improves the purity of the adhesive solution, and the sliding rail installation and door panel design make it easy to clean and replace the filter screen, reducing maintenance costs; Stable and reliable operation: The locking structure prevents the scraping component from shifting, ensuring long-term stable glue application. The overall device has strong adaptability, helping to reduce costs and increase efficiency in the paper sizing process. Attached Figure Description

[0018] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0019] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] refer to Figures 1 to 6 As shown in the figure, an embodiment of the present invention provides a glue filtration device for paper sizing and coating processing, including a glue roller body 1 and a fixed base 2. Both ends of the glue roller body 1 are fixedly connected to a shaft portion 101. Both ends of the top of the fixed base 2 are fixedly connected to a fixed plate 201. The shaft portion 101 is connected to the corresponding fixed plate 201 via bearings. A motor 202 is fixedly installed on the outer wall of the fixed plate 201. The output end of the motor 202 is fixedly connected to the shaft portion 101. Scraping and collecting components are provided on both sides of the glue roller body 1. Filter boxes 6 are installed on both sides of the outer wall of the fixed base 2. The scraping and collecting components include a collecting iron box 3, an adjusting support plate 4, and a support frame 5. A rubber scraper 302 is fixedly connected to the top outer wall of the collecting iron box 3. The bottom side wall of the collecting iron box 3 is connected and fixed to the filter box 6 via a glue discharge pipe 301. The front of the collecting iron box 3 is fixedly connected to the upper end of the adjusting support plate 4 via bolts. The lower end of the adjusting support plate 4 is rotatably mounted on the support frame 5.

[0021] Specifically, one end of the support frame 5 is fixed to the fixed base 2 by bolts, and the inner side of the other end of the support frame 5 is connected to the rotating rod 501 by bearings. The lower end of the adjusting support plate 4 is sleeved and fixed on the rotating rod 501, and the discharge pipe 301 is a flexible hose.

[0022] By adopting the above solution, on the one hand, the rotation of the rotating rod 501 and the adjusting support plate 4 can drive the collecting iron box 3 to rotate around the rotating rod 501, thereby flexibly adjusting the contact angle and pressure between the rubber scraper 302 and the rubber roller body 1, ensuring that the rubber scraper 302 can closely fit the surface of the rubber roller, fully scraping away residual glue at the edges, and solving the problem of insufficient glue collection; on the other hand, the glue discharge pipe 301 made of elastic flexible hose can flexibly deform according to the angle adjustment of the collecting iron box 3, realizing stable connection between the collecting iron box 3 and the filter box 6, providing a guarantee for the integrated transmission of glue from collection to filtration, and reducing the process connection time.

[0023] Specifically, a vertical plate 504 is fixedly connected to the outside of the side wall of the support frame 5. The vertical plate 504 is arranged in an L-shape. A locking screw 503 is threaded through the end of the vertical plate 504. A threaded hole 502 is opened in the middle of one end of the rotating rod 501. The threaded hole 502 is threadedly connected to the locking screw 503.

[0024] Using the above scheme, after adjusting the angle of the collecting iron box 3, tighten the locking screw 503 to lock it into the threaded hole 502 of the rotating rod 501. This can fix the position of the rotating rod 501 and the adjusting support plate 4, preventing the adjusting support plate 4 from shifting due to vibration during the rotation of the rubber roller, and ensuring that the rubber scraper 302 always maintains a stable scraping state.

[0025] Specifically, the inside of the collecting iron box 3 is provided with a liquid collection chamber 304, and a uniformly distributed liquid collection channel 303 is provided between the rubber scraper 302 and the top surface of the collecting iron box 3. The liquid collection chamber 304, the liquid collection channel 303 and the glue discharge pipe 301 are connected. The rubber scraper 302 is provided with an arc-shaped inclined structure to facilitate its contact with the outer surface of the rubber roller body 1.

[0026] By adopting the above scheme, the rubber scraper 302 can be adapted to the outer peripheral surface of the rubber roller body 1, increasing the scraping contact area and fully scraping off the residual rubber liquid at the edge of the rubber roller. The scraped rubber liquid can quickly flow into the collection chamber 304 of the collection box 3 through the collection channel 303. The connection design of the collection chamber 304, the collection channel 303 and the discharge pipe 301 can enable the rubber liquid in the collection chamber 304 to be transported to the filter box 6 in a timely manner through the discharge pipe 301, realizing the seamless connection between rubber liquid collection and filtration, reducing the residence time of rubber liquid in the collection stage and improving the overall processing efficiency.

[0027] Specifically, a coarse filter screen 7 and a fine filter screen 8 are slidably inserted into the interior of the filter box 6 from top to bottom. A door panel 601 is hinged to the front of the filter box 6, and a glue outlet tube 602 is fixedly connected to the bottom side wall of the filter box 6.

[0028] Using the above scheme, the coarse filter 7 can first remove larger particles of paper fibers, glue lumps and other impurities from the glue solution, and the fine filter 8 can further filter out smaller impurities. The combination of the two-stage filtration can significantly improve the purity of the glue solution. The sliding plug-in installation method makes it easy to regularly remove the filter screen for cleaning or replacement, avoiding clogging. The door panel 601 allows operators to easily open the filter box 6 to check the use of the filter screen. There is ample operating space. The glue outlet pipe 602 can directly export the filtered pure glue solution to the storage container or reuse it in the glue application system, realizing resource recycling.

[0029] Specifically, the inner walls on both sides of the filter box 6 are fixedly connected with support slide rails 603, and the coarse filter screen 7 and the fine filter screen 8 are slidably inserted between the corresponding support slide rails 603.

[0030] The above solution provides stable sliding support for the coarse filter 7 and the fine filter 8, making disassembly and assembly convenient.

[0031] The working principle of this utility model: In use, first adjust the scraper collecting component, rotate the adjusting support plate 4 around the rotating rod 501 to make the rubber scraper plate 302 of the collecting iron box 3 fit against the two sides of the rubber roller, then tighten the locking screw 503 to lock the position of the adjusting support plate 4 to prevent shaking and deviation, and ensure the stability of the collecting iron box 3 and the rubber scraper plate 302. Start the motor 202 to drive the rubber roller body 1 to rotate, and the rubber roller with glue on it begins to transfer the paper. At this time, the rubber scraper plate 302 scrapes off the residue on its two sides. The adhesive solution flows into the collection chamber 304 through the collection channel 303, and then is transported to the filter box 6 through the discharge pipe 301. After entering the filter box 6, the adhesive solution first passes through the upper coarse filter screen 7 to remove impurities such as paper fibers and large glue blocks, and then passes through the lower fine filter screen 8 to filter out small impurities. The filtered pure adhesive solution is discharged from the discharge pipe 602 and can be reused in the glue application system or stored. When the filter screen needs to be cleaned, the door panel 601 of the filter box 6 can be opened and the filter screen can be pulled out along the support slide rail 603.
