Technical Field

[0001] This invention relates to the field of sizing machine technology, specifically to a papermaking film transfer sizing machine with adjustable glue volume. Background Technology

[0002] In the modernization process of the paper industry, sizing is a core element that determines paper performance and quality. Its technological upgrades are always closely linked to industry needs. As downstream sectors increasingly demand more refined paper functions, from the burst strength and water resistance of packaging paper to the smoothness and printability of cultural paper, and the customized performance of specialty paper, traditional sizing equipment is gradually becoming unable to meet diversified production needs. Adjustable film transfer sizing machines are key equipment that have emerged in response to this industry upgrade. As the global paper industry transforms towards high quality, low energy consumption, and sustainability, the market's technical requirements for sizing equipment are increasing. Downstream industries such as food packaging and high-end printing are demanding more precise control over the amount of sizing applied to paper.

[0003] Traditional sizing machines may cause paper to wrinkle or shift during sizing due to different paper specifications, which greatly affects the paper quality and makes it difficult to clean quickly and thoroughly. The installation position of the receiving box and metering rod is relatively hidden and inconvenient to disassemble, making it difficult for cleaning personnel to replace the metering rod and unable to thoroughly clean the receiving box, thus reducing production efficiency.

The first connecting block, in conjunction with the first guide plate, guides the paper's lateral position. Simultaneously, the first and second electric sliders slide along the first slide rail, causing the second and third guide plates to assist in clamping the paper from both sides, preventing paper deviation and ensuring accurate entry into the gluing area.

[0006] Preferably, the adhesive application device includes a feeding box and a second slide rail. A third electric slider is slidably connected to the inner wall of the second slide rail. A second connecting plate is fixedly connected to the top of the third electric slider. A heating box is fixedly connected to the top of the second connecting plate.

The second fixing plate is fixedly connected to both sides of the inner wall of the first bracket. One end of the rotating tube is connected to the connecting water pipe. The rotating tube and the connecting water pipe are rotatably connected. After the glue application is completed, the fourth motor drives the third rotating frame to rotate. Through the linkage of the second and first rotating frames, the rotating tube and the cleaning nozzle swing at multiple angles. The connecting water pipe delivers the cleaning liquid in the cleaning liquid tank to the rotating tube. The cleaning liquid is evenly sprayed onto the surface of the glue application roller through the nozzle to dissolve the residual glue. The fifth electric slider slides along the fourth slide rail, driving the cleaning scraper to adhere to the surface of the glue application roller. In conjunction with the rotation of the glue application roller, the scraper thoroughly scrapes off the dissolved glue and impurities and collects them into the collection box.

[0009] This invention provides a papermaking film transfer sizing machine with adjustable adhesive dosage. It has the following beneficial effects:

[0010] 1. This adjustable adhesive film transfer sizing machine for papermaking is equipped with a guiding device. Through a multi-stage adjustment mechanism, it achieves stable paper feeding and precise positioning. A pneumatic piston rod pushes the first and second sizing rollers to contact the paper. With the help of dual motors driving the rollers to rotate, the contact force can be automatically adjusted according to the paper thickness to ensure that papers of different thicknesses can be fed smoothly, avoiding the wrinkling problems caused by thickness differences in traditional feeding. At the same time, a third motor drives the positive and negative ball screws to move the first guide plate laterally, which can quickly calibrate the lateral position of the paper. With the help of the second and third guide plates driven by the first and second electric sliders, it forms a dual guide of lateral calibration and lateral limiting, preventing the paper from deviating during feeding and ensuring that the paper enters the sizing area more stably, improving the stability of sizing and the final product quality.

[0011] 2. This paper-making film transfer sizing machine with adjustable adhesive volume is equipped with a sizing device. After the adhesive is injected into the feed box, it is first preheated by a heating nozzle and evenly sprayed onto the surface of the second sizing roller to prevent the adhesive from solidifying due to cooling when it comes into contact with the roller. Then, the third electric slider synchronously drives the heating box to move and heat the pumped adhesive to ensure that the adhesive maintains optimal fluidity before sizing and avoids the adhesive from becoming viscous and clumping due to low temperature. Finally, the hot air fan blows hot air onto the sizing roller that has been sprayed with adhesive, which not only further spreads the adhesive on the roller surface but also maintains the adhesive temperature to prevent it from cooling down and becoming ineffective before being transferred to the paper. This allows the adhesive to be evenly transferred to the paper surface, improving the sizing efficiency.

[0012] 3. This paper-making film transfer sizing machine with adjustable glue volume is equipped with an adjustment device. By sliding the fourth electric slider on the third slide rail, the pressure between the metering roller and the glue can be precisely adjusted, thereby accurately controlling the glue transfer volume. At the same time, the quick disassembly mechanism drives the second limit rod to fit tightly with the first limit rod through the threaded rod, realizing the quick fixation of the metering roller. During disassembly, it can be pulled out with the assistance of the release spring by simply turning the handle in the opposite direction, which improves the efficiency of replacement and maintenance. This not only enhances the adaptability of the equipment to different sizing needs, but also reduces downtime caused by component replacement, thereby improving work efficiency.

[0013] 4. This paper-making film transfer sizing machine with adjustable adhesive volume is equipped with a cleaning device. A fourth motor drives a third rotating frame to move the cleaning nozzle at multiple angles. With the help of cleaning liquid delivered by the connected water pipe, the cleaning range can be expanded to initially dissolve residual adhesive. Subsequently, a fifth electric slider moves the cleaning scraper to thoroughly scrape off the dissolved adhesive and impurities while the sizing roller is rotating, and collects them into the collection box. This reduces the need for traditional manual disassembly and wiping, lowers the labor intensity of employees, avoids the hardening of adhesive residue from affecting subsequent sizing, ensures long-term stable operation of the equipment, and reduces the scrap rate caused by incomplete cleaning.

[0025] For the first embodiment, please refer to... Figures 1-3This invention provides a technical solution: a papermaking film transfer sizing machine with adjustable glue dosage, comprising a first support 1, with first movable openings 16 on both sides of the first support 1.

A first glue roller 6 is rotatably connected to the side of the first sliding block 4, and the drive shaft of the first motor 5 passes through the first sliding block 4 and is fixedly connected to the first glue roller 6. A second glue roller 7 is rotatably connected to the inner wall of the first support 1, and a second motor is fixedly connected to the side of the first support 1. 8. The drive shaft of the second motor 8 passes through the first bracket 1 and is fixedly connected to the second glue roller 7. A glue application device 9 is fixedly connected to the top of the first bracket 1. Guide devices 10 are fixedly connected to both sides of the first bracket 1. Adjustment devices 2 are fixedly connected to the inner wall of the first bracket 1 on the side of the first glue roller 6 and the second glue roller 7. A first fixing plate 11 is fixedly connected to the inner wall of the first bracket 1. A cleaning liquid tank 12 is fixedly connected to the top of the first fixing plate 11. The inlets of the first high-pressure water pump 13 are connected to both sides of the cleaning liquid tank 12. A connecting water pipe 14 is connected to the outlet of the first high-pressure water pump 13. Cleaning devices 15 are fixedly connected to both sides of the inner wall of the first bracket 1. The guide device 10 includes a first connecting plate 10. 1. A second bracket 102 is fixedly connected to one side of the first connecting plate 101. A sliding box 103 is fixedly connected to the top of the second bracket 102. A positive and negative ball screw 104 is rotatably connected to the inner wall of the sliding box 103. A sliding opening 105 is opened on one side of the sliding box 103. A third motor 106 is fixedly connected to one side of the sliding box 103. The drive shaft of the third motor 106 passes through the sliding box 103 and is fixedly connected to the positive and negative ball screw 104. A second sliding block 107 is sleeved on the positive and negative ball screw 104 and threadedly connected. A first connecting block 108 is fixedly connected to one side of the second sliding block 107. The side of the first connecting block 108 is slidably connected to the inner wall of the sliding opening 105. The first connecting block 108 is away from the second sliding block. A first guide plate 109 is fixedly connected to one side of the second bracket 102. A third bracket 1010 is fixedly connected to both sides of the second bracket 102. A first slide rail 1011 is fixedly connected to the top of the third bracket 1010. A first electric slider 1012 and a second electric slider 1013 are slidably connected to the inner wall of the first slide rail 1011. A second guide plate 1014 is fixedly connected to the side of the first electric slider 1012. A third guide plate 1015 is fixedly connected to the side of the second electric slider 1013. A first connecting plate 101 is fixedly connected to one side of the first bracket 1. The first connecting plate 101 is symmetrically arranged on both sides of the first bracket 1. Two sets of second sliding blocks 107 are provided and symmetrically distributed on the positive and negative ball screws 104.

[0026] In use, after the paper passes between the first gluing roller 6 and the second gluing roller 7, the pneumatic piston rod 3 pushes the first sliding block 4 to slide within the first movable opening 16, thereby causing the first gluing roller 6 and the second gluing roller 7 to contact the paper. Then, the first motor 5 and the second motor 8 are started, driving the first gluing roller 6 and the second gluing roller 7 to rotate for subsequent gluing, thus ensuring smooth material conveying and avoiding wrinkles, and adapting to the gluing requirements of paper of different thicknesses. Then, the third motor 106 is started, and the drive shaft of the third motor 106 rotates, driving the forward and reverse ball screws 104 to rotate within the sliding box 103. Since the second sliding block 107 and the forward and reverse ball screws 104 are screwed together... The two sets of second sliding blocks 107 are connected by a sliding box 103 and limited by the inner wall. They move towards or away from each other along the positive and negative ball screws 104. This causes the first guide plate 109 to move synchronously through the first connecting block 108, thus guiding the paper's lateral position. At the same time, according to the paper thickness, the first electric slider 1012 and the second electric slider 1013 are controlled to slide on the first slide rail 1011, causing the second guide plate 1014 and the third guide plate 1015 to move. This provides auxiliary clamping and guidance for the paper from both sides, preventing wrinkles and deviations during the conveying process. This ensures that the paper can accurately enter the gluing area, improving the uniformity and stability of the gluing.

[0027] For the second embodiment, please refer to... Figures 1-4 Based on the first embodiment, the present invention provides a technical solution: the glue application device 9 includes a feeding box 91 and a second slide rail 92. A third electric slider 93 is slidably connected to the inner wall of the second slide rail 92. A second connecting plate 94 is fixedly connected to the top of the third electric slider 93. A heating box 95 is fixedly connected to the top of the second connecting plate 94. A hot air fan 96 is uniformly fixedly connected to the top of the second connecting plate 94. A glue application pipe 97 is uniformly connected to one side of the heating box 95. Connecting conduits 98 are connected to both sides of the heating box 95. The inlets of a second high-pressure water pump 99 are connected to both sides of the feeding box 91. The end of the connecting conduit 98 away from the heating box 95 is connected to the outlet of the second high-pressure water pump 99. A heating spray pipe 910 is uniformly connected to one side of the feeding box 91. The feeding box 91 is fixedly connected to the top of the first support 1 on one side of the first glue application roller 6. The second high-pressure water pump 99 is fixedly connected to the top of the first support 1. The second slide rail 92 is fixedly connected to the top of the first support 1 on one side of the second glue application roller 7.

[0028] In use, the adhesive is first injected into the feeding box 91. The heated adhesive is then evenly sprayed onto the surface of the second application roller 7 after being heated by the heating nozzle 910. This helps maintain the fluidity of the adhesive and prevents solidification. Then, the third electric slider 93 slides synchronously within the second slide rail 92 as the first application roller 6 moves, moving the second connecting plate 94 and its heating box 95 to a suitable position. At this time, the second high-pressure water pump 99 starts, pumping the adhesive from the feeding box 91 into the heating box 95 through the connecting conduit 98. The adhesive is then heated within the heating box 95. Heat is used to ensure that the adhesive maintains a suitable temperature and fluidity before application. Subsequently, the adhesive is evenly sprayed onto the first application roller 6 through the application tube 97. Then, the hot air fan 96 is activated to blow hot air onto the application roller after the adhesive has been sprayed, so that the adhesive adheres more evenly to the surface of the application roller and can further maintain the temperature of the adhesive, preventing it from affecting the application effect due to temperature drop during the spraying process. As the first application roller 6 and the second application roller 7 rotate, the adhesive is evenly transferred to the paper surface, realizing an efficient and uniform application process and ensuring the application quality.

[0029] Third embodiment, please refer to Figures 1-7 Based on the second embodiment, the present invention provides a technical solution: the adjusting device 2 includes a third slide rail 21, a fourth electric slider 22 is slidably connected to the inner wall of the third slide rail 21, a quick disassembly mechanism 23 is fixedly connected to the side of the fourth electric slider 22 away from the third slide rail 21, a third connecting plate 24 is fixedly connected to one side of the quick disassembly mechanism 23, a metering roller 25 is rotatably connected to the inner wall of the third connecting plate 24, the third slide rail 21 is fixedly connected to both sides of the inner wall of the first bracket 1, the quick disassembly mechanism 23 includes a disassembly box 231, a release spring 232 is fixedly connected to one side of the inner wall of the disassembly box 231, a limiting slide table 233 is fixedly connected to the bottom of the inner wall of the disassembly box 231, a limiting groove 234 is opened on the top of the limiting slide table 233, a sliding table 235 is slidably connected to the inner wall of the limiting groove 234, and a connecting rod is fixedly connected to the top of the sliding table 235. The connecting rod 236 has a first limiting rod 237 fixedly connected to one side. The disassembly box 231 has an adjusting box 238 fixedly connected to one side. A threaded rod 239 is threaded through and threaded to one side of the inner wall of the adjusting box 238. A disassembly handle 2310 is fixedly connected to one end of the threaded rod 239 away from the disassembly box 231. A second limiting rod 2311 is rotatably connected to one end of the threaded rod 239 away from the disassembly handle 2310. The side of the second limiting rod 2311 is slidably connected to the inner wall of the adjusting box 238. The second limiting rod 2311 passes through the disassembly box 231 and extends into the interior of the disassembly box 231. A second connecting block 2312 is fixedly connected to one end of the connecting rod 236 away from the release spring 232. One side of the disassembly box 231 is fixedly connected to a fourth electric slider 22. One side of the second connecting block 2312 is fixedly connected to a third connecting plate 24.

[0030] In use, when the position of the metering roller 25 needs to be adjusted to adapt to different application rates, the fourth electric slider 22 is controlled to slide within the third slide rail 21, driving the quick-release mechanism 23 and the metering roller 25 to move to the target position. This adjusts the pressure between the metering roller 25 and the adhesive, thereby adjusting the application rate and ensuring a uniform adhesive layer is formed on the surface of the application roller. If quick replacement or maintenance of the metering roller 25 is required, during installation, the sliding table 235 is inserted into the limiting groove 234, and the connecting rod 236 and the first limiting rod 237 enter the disassembly box 231. When moved to the appropriate position, the release spring 232 is compressed, and then the disassembly handle 2310 is rotated to drive the threaded rod 239 to rotate within the adjusting box 238. Because the threaded rod 239 is threadedly connected to the adjusting box 238 and the second limiting rod 2311 is limited by the inner wall of the adjusting box 238, the second limiting rod 2311 moves axially along the threaded rod 239. When the second limiting rod 2311 moves to contact and press against the first limiting rod 237, the first limiting rod 237 and the second limiting rod 2311 fit tightly together, thereby stably limiting the sliding table 235 within the limiting groove 234, realizing the quick installation of the metering roller 25. When replacement or disassembly is required, the disassembly handle 2310 is rotated in the reverse direction, and the second limiting rod 2311 separates from the first limiting rod 237. With the assistance of the elastic force of the release spring 232, the connecting rod 236 is pulled out. At this time, the sliding table 235 can be directly pulled out from the limiting groove 234, completing the quick disassembly of the metering roller 25. This greatly improves the efficiency of equipment maintenance and parts replacement, reduces downtime, and ensures the continuity of production. At the same time, through the cooperation of the fourth electric slider 22 and the third slide rail 21, the precise adjustment of the position of the metering roller 25 is realized, and the pressure between the metering roller 25 and the glue roller can be precisely controlled, thereby realizing the precise adjustment of the glue application amount and improving the adaptability of the device.

[0032] During use, after the glue application is completed, to ensure the cleanliness of the glue application roller and conveying path and avoid glue residue affecting subsequent production, firstly, the drive shaft of the fourth motor 158 rotates, driving the third rotating frame 157 to rotate. Through the linkage of the second rotating frame 156 and the first rotating frame 155, the rotating tube 153 and its cleaning nozzle 154 swing at multiple angles. At the same time, the water pipe 14 delivers the cleaning liquid from the cleaning liquid tank 12 to the rotating tube 153, and sprays it evenly on the surface of the glue application roller through the cleaning nozzle 154 to initially dissolve and rinse the residual glue, thereby expanding the cleaning range. Subsequently, the fifth electric slider 1511 slides on the fourth slide rail 1510, driving the cleaning scraper 1512 to move to the surface of the glue application roller. Under the rotation of the glue application roller, the dissolved glue and impurities are thoroughly scraped off and collected in the collection box 152, thereby achieving the best cleaning effect, reducing the labor intensity of workers, and improving work efficiency.
