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.

[0031] Example 1

[0032] like Figure 1 As shown;

[0033] An automatic resin coating device for both ends of a paper tube includes a frame 1 and a paper tube 11 to be coated with resin, which is arranged above the frame 1.

[0034] In this implementation plan: Traditional paper tube resin coating methods mostly rely on manual operation. This method is not only inefficient, but also makes it difficult to ensure the uniformity of resin coating, easily resulting in over- or under-coating, affecting the quality of the paper tube. Furthermore, manual coating also suffers from high labor intensity and production costs. With the development of the paper tube manufacturing industry, higher demands are placed on the automation, efficiency, and precision of resin coating at both ends of the paper tube. To solve this technical problem, a conveying mechanism 2, a resin coating mechanism 3, and a resin supply mechanism 4 are added to this basis.

[0035] Furthermore:

[0036] like Figures 1 to 6 As shown:

[0037] In combination with the above: it also includes;

[0038] Conveying mechanism 2 includes a base plate 25 disposed on the surface of frame 1, a fixing plate 21 fixedly connected to the surface of base plate 25, and an inclined groove 22 fixedly connected to the surface of fixing plate 21.

[0039] The resin coating mechanism 3 includes an electric slide 313 fixedly connected to the surface of the base plate 25. A propulsion cylinder 311 is mounted on the mounting surface of the electric slide 313. A sponge head 312 coated with resin is mounted on the piston rod end of the propulsion cylinder 311.

[0040] The resin supply mechanism 4 includes an oil storage box 44 for storing resin, which is fixedly connected to the surface of the base plate 25. An anilox roller 45 is rotatably connected to the inner side of the oil storage box 44.

[0041] In this implementation scheme: A frame 1 is set up, which serves as the basic structure of the entire device. A conveying mechanism 2 is set up, which conveys the paper tube 11 through an inclined groove 22. Due to the inclined angle of the groove 22, the paper tube 11 will roll along the inclined groove 22 under the action of gravity, which is conducive to the subsequent coating work. A base plate 25 is set up to provide a mounting base for subsequent components. A resin coating mechanism 3 is set up and is mounted on the base plate 25 by an electric slide table 313. The surface of the electric slide table 313 is fixed. During the movement of the mounting platform, the propulsion cylinder 311 mounted on its surface is driven, so that the sponge head 312 can accurately reach the positions at both ends of the paper tube 11 that need to be coated. By setting the resin supply mechanism 4, after the coating resin mechanism 3 completes the coating operation of one paper tube 11, the sponge head 312 moves to the anilox roller 45 through the coordinated action of the electric slide table 313 and the propulsion cylinder 311, picks up the resin on the anilox roller 45, and then returns to the coating resin station to continue the next coating resin operation, and so on.

[0042] It should be noted that the electric slide table 313 is mainly composed of a motor, lead screw, guide rail, guide block and mounting table. The motor outputs the rotation of the lead screw, which causes the mounting table to slide on the surface of the guide rail through the guide block. The surface of the anilox roller 45 is provided with a scraper. The amount of oil applied to the anilox roller 45 can be controlled by adjusting the gap between the scraper and the anilox roller 45.

[0043] Furthermore:

[0044] In an optional embodiment, a slide rail 23 is fixedly connected to the surface of the frame 1, and a slider 24 is slidably connected to the surface of the slide rail 23. The upper surface of the slider 24 is fixedly connected to the bottom surface of the base plate 25.

[0045] In this embodiment: by setting a slide rail 23 on the surface of the frame 1, the slider 24 slides on the slide rail 23, and the base plate 25 is connected to the slider 24, so that the base plate 25 can move on the surface of the frame 1 through the slider 24.

[0046] It should be noted that: since the fixed plate 21 is fixedly connected to the surface of the base plate 25, and the inclined groove 22 is fixedly connected to the surface of the fixed plate 21, the width of the conveying mechanism 2 can be adjusted by adjusting the position of the base plate 25 to meet the conveying requirements of paper tubes 11 of different specifications.

[0047] Furthermore:

[0048] In an optional embodiment, two sets of sliders 24 and base plates 25 are symmetrically arranged on the surface of the frame 1.

[0049] In this embodiment, since two sets of sliders 24 and base plates 25 are symmetrically arranged on the surface of the frame 1, this design can further improve the positioning effect of the paper tube 11.

[0050] Furthermore:

[0051] In an optional embodiment, a guide post 31 is fixedly connected to the surface of the base plate 25, a limit plate 32 is fixedly connected to the upper end of the guide post 31, a bearing plate 33 is slidably connected to the surface of the guide post 31, a drive motor 35 is mounted on the bottom surface of the bearing plate 33 through a mounting bracket 34, and a drive roller 36 is fixedly connected to the output end of the drive motor 35.

[0052] In this embodiment: A drive motor 35 is installed above the paper tube 11 via a guide post 31 and a limiting plate 32. The output shaft of the drive motor 35 is connected to the drive roller 36. The drive roller 36 is in contact with the surface of the paper tube 11. When the drive motor 35 starts, it drives the drive roller 36 to rotate, thereby driving the paper tube 11 to rotate around its own axis.

[0053] Furthermore:

[0054] In an optional embodiment, a rotary valve 315 is mounted on the upper surface of the limiting plate 32, and a threaded rod 314 is fixedly connected to the bottom surface of the rotary valve 315. The threaded rod 314 is threadedly connected to the bearing plate 33 and rotatably connected to the limiting plate 32.

[0055] In this embodiment: the rotary valve 315 is installed on the limiting plate 32. When the rotary valve 315 rotates, it will drive the threaded rod 314 connected to it to rotate. Since the threaded rod 314 is threadedly connected to the bearing plate 33, the rotation of the threaded rod 314 will cause the bearing plate 33 to move up and down along the guide post 31.

[0056] Furthermore:

[0057] In an optional embodiment, a mounting bracket 37 is fixedly connected to the surface of the base plate 25, a lifting cylinder 38 is mounted on the surface of the mounting bracket 37, a lifting frame 39 is fixedly connected to the extended end of the lifting cylinder 38, and two lifting rollers 310 are symmetrically rotatably connected to the surface of the lifting frame 39.

[0058] In this embodiment: because a lifting cylinder 38 is provided, when the paper tube 11 reaches the resin coating station, the lifting cylinder 38 lifts the paper tube 11 to a set height through the lifting frame 39 and two lifting rollers 310 installed on the surface of the lifting frame 39, in preparation for the subsequent resin coating operation.

[0059] Furthermore:

[0060] In an optional embodiment, a drive motor 41 is mounted on the bottom surface of the base plate 25, and the drive motor 41 and the anilox roller 45 are driven by a drive wheel set 43.

[0061] In this embodiment: the drive motor 41 drives the anilox roller 45 to rotate through the drive wheel set 43. The anilox roller 45 is partially immersed in the resin in the oil storage box 44 and picks up the resin during the rotation.

[0062] Furthermore:

[0063] In an optional embodiment, the surface of the base plate 25 is provided with a square groove 42 for facilitating transmission between the drive motor 41 and the anilox roller 45.

[0064] In this embodiment: because a square groove 42 is provided, the transmission motor 41 can further facilitate the transmission of the anilox roller 45.

[0065] Furthermore:

[0066] In an optional embodiment, a baffle plate 26 is mounted on the surface of the base plate 25, and the surface of the baffle plate 26 has a groove for holding the paper tube 11.

[0067] In this embodiment: because a baffle plate 26 is provided and the surface of the baffle plate 26 is provided with a groove, the paper tube 11 can be placed through the groove on the surface of the baffle plate 26.

[0068] It should be noted that the baffle plate 26 is installed on the surface of the base plate 25 through the cooperation between the moving block, the moving rail and the positioning pin, so that the position of the baffle plate 26 can be adjusted.

[0069] The paper tube resin coating equipment also includes a control system, which is connected to the conveying mechanism 2, the resin coating mechanism 3 and the resin supply mechanism 4 via electrical lines to achieve centralized control and coordination of the entire equipment operation.

[0070] Parameter Setting and Automated Operation: The control system features a human-machine interface, allowing operators to set key parameters such as conveying speed, resin coating time, and resin supply quantity. Based on preset parameters, the system automatically controls the operating speed of the conveying mechanism 2, the sequence and timing of the resin coating mechanism 3, and the resin supply quantity of the resin supply mechanism 4, thereby automating the resin coating operation of the paper tube.

[0071] Working Principle: A frame 1 forms the basic structure of the entire device. A conveying mechanism 2 transports the paper tube 11 via an inclined trough 22. Due to the angle of the trough 22, the paper tube 11 rolls along it under gravity, facilitating subsequent coating. A base plate 25 provides the mounting foundation for subsequent components. A resin coating mechanism 3, mounted on the base plate 25 via an electric slide 313, moves along the surface of the slide 313, driving a propulsion cylinder 311 to accurately reach the coating positions at both ends of the paper tube 11. A resin supply mechanism 4... After the resin coating mechanism 3 completes the coating operation on one paper tube 11, the sponge head 312 moves to the anilox roller 45 through the coordinated action of the electric slide table 313 and the push cylinder 311, picks up the resin on the anilox roller 45, and then returns to the resin coating station to continue the next resin coating operation. This process is repeated. By setting the slide rail 23 on the surface of the frame 1, the slider 24 slides on the slide rail 23, and the base plate 25 is connected to the slider 24, so that the base plate 25 can move on the surface of the frame 1 through the slider 24. Since there are two sets of sliders 24 and base plates 25 symmetrically arranged on the surface of the frame 1, this design can further improve the positioning effect of the paper tube 11. Above the paper tube 11, the guide post 31 and the limit The position plate 32 is equipped with a drive motor 35. The output shaft of the drive motor 35 is connected to the drive roller 36, which is in contact with the surface of the paper tube 11. When the drive motor 35 starts, it drives the drive roller 36 to rotate, thereby driving the paper tube 11 to rotate around its own axis. A rotary valve 315 is installed on the limit plate 32. When the rotary valve 315 rotates, it drives the threaded rod 314 connected to it to rotate. Since the threaded rod 314 is threadedly connected to the support plate 33, the rotation of the threaded rod 314 will cause the support plate 33 to move up and down along the guide post 31. Because a lifting cylinder 38 is provided, when the paper tube 11 reaches the resin coating station, the lifting cylinder 38 lifts the paper tube 11 through the lifting frame 39 and two lifting rollers 310 installed on the surface of the lifting frame 39. The paper tube 11 is lifted to a set height to prepare for the subsequent resin coating operation. The drive motor 41 drives the anilox roller 45 to rotate through the drive wheel set 43. The anilox roller 45 is partially immersed in the resin in the oil storage box 44 and picks up the resin during rotation. Because a square groove 42 is provided, the drive motor 41 can further drive the anilox roller 45. Because a baffle plate 26 is provided and the surface of the baffle plate 26 has a groove, the paper tube 11 can be placed through the groove on the surface of the baffle plate 26. The paper tube resin coating equipment also includes a control system. The control system is connected to the conveying mechanism 2, the resin coating mechanism 3 and the resin supply mechanism 4 through electrical lines to realize centralized control and coordination of the operation of the entire equipment.

[0072] Parameter Setting and Automated Operation: The control system features a human-machine interface, allowing operators to set key parameters such as conveying speed, resin coating time, and resin supply quantity. Based on preset parameters, the system automatically controls the operating speed of the conveying mechanism 2, the sequence and timing of the resin coating mechanism 3, and the resin supply quantity of the resin supply mechanism 4, thereby automating the resin coating operation of the paper tube.

[0073] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
