Description

Technical Field

[0001] The utility model relates to the technical field of paper gluing equipment, in particular to an adjustable paper gluing roller. Background Art

[0002] Paper is a thin sheet made of plant fibers and is used for writing, painting, printing newspapers and books, packaging, etc. When paper is used for special work, it usually needs to be treated with glue, and thus a gluing roller is required.

[0003] In the prior art, the patent publication number is: CN219850400U, which discloses a paper gluing roller, including a roller body. A gluer is fixedly inserted into the roller body. A cavity is opened in the roller body. A glue outlet groove is opened around the cavity and communicated with the cavity. An overflow groove is opened at the outer end of the glue outlet groove, and the overflow groove is communicated with the outside of the roller body. The gluer includes a glue outlet pipe and a glue inlet head. The glue outlet pipe is movably or fixedly connected with the glue inlet head, and the glue outlet pipe is inserted into the cavity and fixedly arranged. In the utility model, the method of gluing on the inner side of the roller body is adopted, and dot gluing is changed to line gluing, and the gluing is continuous and uniform. The glue outlet groove adopts a structure bent outwards, and the glue liquid is discharged smoothly without blockage.

[0004] Although the above paper gluing roller can make the glue liquid discharge smoothly through the settings such as the glue outlet groove and the overflow groove, in actual application, there are still the following deficiencies: the height of the gluing roller is fixed and cannot be adjusted according to the actual situation, and it is extremely troublesome to clean the glue on the surface of the gluing roller. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an adjustable paper gluing roller aiming at the problems existing in the background art.

[0006] To achieve this purpose, the utility model adopts the following technical scheme: an adjustable paper gluing roller, including a fixing frame. Both ends of the bottom side of the fixing frame are fixedly installed with fixing blocks, and two fixing holes are opened on each fixing block. An anti-collision port is opened on the top wall of the fixing frame. A lifting component is arranged inside the fixing frame, and a gluing roller component is fixedly installed on the lifting component, and a cleaning component is arranged on the gluing roller component.

[0007] Preferably, the lifting component includes installation grooves opened on the inner walls of both sides of the fixing frame. A guiding sliding column is fixedly installed on the upper and lower sides of one of the installation grooves, and a threaded rod is rotatably installed on the upper and lower sides of the other installation groove.

[0022] As Figures 1-3As shown in the figure, an adjustable paper gluing roller proposed by the utility model includes a fixing frame 1. Both ends of the bottom side of the fixing frame 1 are fixedly installed with fixing blocks 11. Two fixing holes 12 are respectively opened on the fixing blocks 11. An anti-collision port 13 is opened on the top wall of the fixing frame 1. A lifting component 2 is arranged inside the fixing frame 1. A gluing roller component 3 is fixedly installed on the lifting component 2. A cleaning component 4 is arranged on the gluing roller component 3.

[0023] In this embodiment: The lifting component 2 includes installation grooves 21 opened on the inner walls of both sides of the fixing frame 1. Guide sliding columns 22 are fixedly installed together on the upper and lower sides of one of the installation grooves 21. A threaded rod 23 is rotatably installed together on the upper and lower sides of the other installation groove 21. A servo motor 24 is fixedly installed on the top of the fixing frame 1. The output end of the servo motor 24 penetrates through the top wall of the fixing frame 1 and is fixedly connected to the top end of the threaded rod 23. Through this setting, starting the servo motor 24 can drive the threaded rod 23 to rotate in the other installation groove 21. A lifting plate 25 is slidably sleeved together on the outer peripheries of the threaded rod 23 and the guide sliding columns 22. Through this setting, when the threaded rod 23 rotates, it will drive the lifting plate 25 to move up and down on the outer peripheries of the guide sliding columns 22 and the threaded rod 23. The gluing roller component 3 includes an installation frame 31 fixedly installed at the bottom of the lifting plate 25. A gluing roller 32 is rotatably installed inside the installation frame 31. A driving motor 33 is fixedly installed on the side wall of the installation frame 31. The output end of the driving motor 33 penetrates through the side wall of the installation frame 31 and is fixedly connected to one side of the gluing roller 32. Through this setting, the installation frame 31 rises and falls with the lifting of the lifting plate 25. Starting the driving motor 33 can drive the gluing roller 32 to rotate inside the installation frame 31. A heating rod 34 is fixedly installed inside the gluing roller 32. A plurality of air permeation holes 35 are evenly opened on the outer walls of both sides of the gluing roller 32. Through this setting, starting the heating rod 34 can heat the glue on the periphery of the gluing roller 32 to make the glue at a suitable temperature when applying to the paper. At the same time, after heating the solidified glue, it is convenient to clean it. The heat inside the gluing roller 32 can be discharged through the air permeation holes 35, and the air pressure inside and outside the gluing roller 32 can be kept balanced. Embodiment

[0024] As Figures 1-3As shown in the figure, a kind of adjustable paper gluing roller proposed by the utility model, compared with the first embodiment, this embodiment further includes that the cleaning component 4 includes chutes 41 opened on the inner walls of both sides of the mounting frame 31. A connecting plate 42 is slidably installed on the two chutes 41 together. A scraper 43 is fixedly installed at the bottom of the connecting plate 42. A cylinder 44 is fixedly installed on the top of the mounting frame 31. The telescopic end of the cylinder 44 penetrates through the top wall of the mounting frame 31 and is fixedly connected to the top of the connecting plate 42. Through this setting, starting the cylinder 44 can drive the connecting plate 42 to move up and down in the two chutes 41, thereby driving the scraper 43 to move up and down. When it is necessary to clean the glue on the surface of the coating roller 32, just start the cylinder 44 to lower the scraper 43 until it abuts against the surface of the coating roller 32. The cylinder 44 is located directly below the anti-collision port 13. Through this setting, the cylinder 44 can pass through the anti-collision port 13 to avoid the cylinder 44 colliding with the inner wall of the top of the fixed frame 1.

[0025] Working principle: When using this device, start the servo motor 24 to drive the threaded rod 23 to rotate in the installation groove 21, thereby driving the lifting plate 25 to slide up and down around the guiding slide post 22 and the threaded rod 23. The lifting plate 25 drives the mounting frame 31 fixedly installed at its bottom to lift and lower. The mounting frame 31 drives the coating roller 32 rotatably installed inside it to lift and lower. Until the coating roller 32 is adjusted to a suitable height, start the heating rod 34 according to the ambient temperature and the solidification condition of the glue on the surface of the coating roller 32. The heating rod 34 can heat the inside of the coating roller 32, and the heat is transferred from the inside of the coating roller 32 to the periphery of the coating roller 32, so as to keep the glue in a suitable state. When it is necessary to clean the glue on the outer surface of the coating roller 32, start the cylinder 44 to drive the connecting plate 42 to slide down in the two chutes 41 until the scraper 43 abuts against the surface of the coating roller 32. Start the driving motor 33 to drive the coating roller 32 to rotate, so that the scraper 43 cleans the glue on the outer surface of the rotating coating roller 32.
