Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3This utility model provides an embodiment of a paper surface sizing uniformity control mechanism, comprising a worktable 1, which provides support and improves the overall stability of the mechanism's operation. Two support rods 2 are fixedly connected to the top of the worktable 1, providing support for the two support rods 2. The two support rods 2 have internal grooves, which enhance the load-bearing capacity of the two support rods 2. A fixing plate 3 is fixedly connected to the top of the worktable 1, providing fixation for the worktable 1. The fixing plate 3 increases the weight at the bottom of the mechanism, improving its operational stability. A drive assembly is fixedly connected inside the fixing plate 3, providing fixation for the drive assembly and preventing vibration during operation. The drive assembly includes a cylinder 4, which is externally fixedly connected inside the fixing plate 3. The cylinder 4 provides driving force, and the fixing plate 3 provides support for the cylinder 4, reducing vibration during operation and improving the stability of the cylinder 4. A drive shaft 5 is fixedly connected to the drive end of the cylinder 4, providing the drive source for the displacement of the drive shaft 5 by activating the cylinder 4. A sliding plate 6 is fixedly connected to the front end of the drive assembly, and the drive assembly provides power for the sliding plate 6 to slide. The front end of the drive shaft 5 is fixedly connected to the rear end of the sliding plate 6, and the displacement of the drive shaft 5 pushes the sliding plate 6 to slide.

[0034] The bottom of the sliding plate 6 is slidably connected to the top of the worktable 1. The worktable 1 provides support for the sliding of the sliding plate 6, preventing it from deviating during sliding and improving its sliding stability. Two rotating rods 7 are rotatably connected inside the plate 6. The sliding plate 6 is connected to the rotating rods 7 via shafts, and the sliding of the sliding plate 6 drives the two rotating rods 7 to rotate. A sliding shaft 8 is rotatably connected inside the two rotating rods 7. The sliding shaft 8 is slidably connected to the inside of two support rods 2, providing support for the rotation of the two rotating rods 7. The support rods 2 have internal grooves, allowing the sliding shaft 8 to slide within the support rods 2. A sliding roller 9 is rotatably connected to the outside of the sliding shaft 8. The sliding of the sliding shaft 8 drives the sliding roller 9 to slide, thereby adjusting the paper tension. The adjacent ends of the two rotating rods 7 are rotatably connected to the distant ends of the sliding roller 9, providing limits for the rotation of the sliding roller 9 and preventing it from deviating during rotation. Two fixed rods 10 are fixedly connected to the top of the worktable 1, providing support and load-bearing capacity for the two fixed rods 10. A rotating shaft 11 is fixedly connected inside the two fixed rods 10, serving as the rotation center axis. The fixed rods 10 provide support for the rotating shaft 11, improving its load-bearing capacity. A rotating roller 12 is rotatably connected to the outside of the rotating shaft 11. The rotating roller 12 receives the paper feed, and the rotating shaft 11 supports the rotation of the rotating roller 12, improving its rotational stability.

[0035] Two support columns 13 are fixedly connected to the top of the workbench 1. These support columns 13 serve as the main support pillars of the mechanism, and the workbench 1 provides fixation for the two support columns 13, thereby improving their load-bearing capacity. A fixing block 14 is fixedly connected to the left end of one of the support columns 13, providing fixation for the fixing block 14 and improving its stability. A horizontal plate 15 is fixedly connected to the rear end of each of the two support columns 13. The horizontal plate 15 has an internal rotating shaft and serves as a connecting plate. The support columns 13 provide support for the horizontal plate 15, thereby improving its connection stability. Motors 16 are fixedly connected inside each of the two fixing blocks 14, providing fixation for the motors 16 and preventing vibration during operation, thus improving their operational stability. The external rotatable connection of one of the motors 16 is to the interior of the two support columns 13, which support the rotation of the motor 16 and prevent it from shifting during rotation, thus improving the rotational stability of the motor 16. Two horizontal plates 15 are rotatably connected to adjacent ends of each other, with a rotating plate 17. The horizontal plates 15 are rotatably connected to the rotating plates 17 via shafts, thus providing support for the rotation of the rotating plates 17. Another motor 16 is externally rotatably connected to the inside of the two rotating plates 17, which provide support for the rotation of the other motor 16, thereby improving the rotational stability of the other motor 16.

[0036] Reference Figures 3 to 5 One rotating plate 17 has a fixed block 14 fixedly connected to its left end, providing fixation for the rotating plate 17 and the fixed block 14, which supports the motor 16, thereby improving the load-bearing capacity of the fixed block 14. Support blocks 18 are fixedly connected to the rear ends of both rotating plates 17, providing support for the two support blocks 18, thereby improving the load-bearing capacity of the two support blocks 18. One glue spraying frame 19 is fixedly connected to the top of each of the two support columns 13, and the other glue spraying frame 19 is fixedly connected to the top of each rotating plate 17. The glue spraying frame 19 is used to fix the nozzle that sprays glue. The support columns 13 and rotating plates 17 respectively fix the two glue spraying frames 19, thereby improving the stability of the glue spraying frames 19 when the nozzle sprays glue. Glue rollers 20 are fixedly connected to the drive ends of both motors 16. Starting the motors 16 drives the two glue rollers 20 to rotate, and the rotation of the two glue rollers 20 causes the glue to adhere evenly to the paper surface. The two support blocks 18 are internally slidably connected to a telescopic rod 22. The support blocks 18 are provided with a sliding groove to guide the sliding of the telescopic rod 22 and thus improve the sliding stability of the telescopic rod 22.

[0037] The telescopic rod 22 is externally slidably connected to a support plate 21. The support plate 21 has internal grooves to guide the sliding of the telescopic rod 22 and prevent it from deviating during sliding. Two springs 23 are sleeved on the outside of the telescopic rod 22, providing support for the springs 23 and ensuring even force distribution, preventing deviation. The adjacent ends of the two springs 23 are fixedly connected to the left and right ends of the support plate 21, which in turn supports the springs 23, reducing pressure and extending their service life. Two baffles 24 are fixedly connected to the outside of the telescopic rod 22. The contraction of the telescopic rod 22 causes the baffles 24 to shift. The distant ends of the two springs 23 are fixedly connected to the adjacent ends of the two baffles 24. The displacement of the baffles 24 compresses the springs 23, causing them to deform under stress. Sliding blocks 25 are slidably connected inside both support blocks 18. The left and right ends of the telescopic rod 22 are in contact with the adjacent ends of the two sliding blocks 25 respectively. By sliding the sliding blocks 25, the sliding blocks 25 squeeze the telescopic rod 22 inside the support block 18, causing the telescopic rod 22 to detach from the inside of the support block 18.

[0038] The support plate 21 is fixedly connected to two fixed shafts 26. The fixed shafts 26 serve as guides, and the support plate 21 provides fixation for the fixed shafts 26, improving the guiding stability of the fixed shafts 26. A support shaft 27 is slidably connected inside the support plate 21. The support plate 21 has a groove inside, which guides the sliding of the support shaft 27. Simultaneously, the support shaft 27 provides support for the support plate 21, improving its stability. The left and right ends of the support shaft 27 are slidably connected to the interior of two support blocks 18, respectively. The support blocks 18 guide the sliding of the support shaft 27, and the support shaft 27 connects the support blocks 18 and the support plate 21. The support shaft 27 is slidably connected to the exterior of the two fixed shafts 26. A scraper 28 is fixedly connected to the exterior of the support shaft 27. The scraper 28 contacts the exterior of the glue roller 20. The sliding of the support shaft 27 drives the scraper 28 to slide, allowing the scraper 28 to clean the glue on the surface of the glue roller 20. Two springs 29 are sleeved on the outside of the fixed shaft 26. The front ends of the two springs 29 are fixedly connected to the outside of the support shaft 27. Through the contact between the scraper 28 and the glue roller 20, the scraper 28 drives the support shaft 27 to squeeze the springs 29, causing the springs 29 to store force and deform. The springs 29 release their elastic force, and the support shaft 27 drives the scraper 28 to squeeze the glue roller 20, thereby improving the cleaning efficiency of the surface of the glue roller 20.

[0039] Working principle: When the paper enters the mechanism, the cylinder 4 is activated, which drives the drive shaft 5 to move. At the same time, the drive shaft 5 pushes the sliding plate 6 to slide. The sliding plate 6 drives two rotating rods 7 to rotate through the shaft. The two rotating rods 7 are supported by the sliding shaft 8. Through the sliding grooves inside the two support rods 2, the two rotating rods 7 drive the sliding shaft 8 to slide inside the two support rods 2. The sliding of the sliding shaft 8 drives the sliding roller 9 to slide, thereby adjusting the tension of different papers, so that the paper is evenly glued.

[0040] Two motors 16 are activated to drive two gluing rollers 20 to rotate. The rotating plate 17 is used to adjust the gap between the two gluing rollers 20, thus uniformly applying glue to the paper surface. At this time, the scraper 28 contacts the gluing rollers 20. The rotation of the gluing rollers 20 causes the scraper 28 to clean the glue on their surface. Simultaneously, under the action of two springs 29, the support shaft 27 causes the scraper 28 to fit tightly against the surface of the gluing rollers 20, improving cleaning efficiency. Pulling the two sliding blocks 25 causes them to compress the spring 23, thus disassembling the scraper 28. Pressing the two sliding blocks 25 compresses the telescopic rod 22. The two telescopic rods 22 then drive the baffle 24 to compress the spring 23, causing the spring 23 to store force. When the spring 23 releases its elastic force, the baffle 24 drives the telescopic rod 22 to reset, fixing the telescopic rod 22 inside the support block 18, thereby fixing the scraper 28.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
