[0036] The top side of the device body 1 is provided with a curing device 6, which comprises a U-shaped guard plate 61 and a triangular-shaped rod 62. The U-shaped guard plate 61 is fixed to the top of the device body 1, one vertical support rod of the triangular-shaped rod 62 is fixed to the top of the moving plate 32, the other two vertical support rods of the triangular-shaped rod 62 penetrate through the top of the U-shaped guard plate 61, and a UV curing lamp 63 is fixed between the other two vertical support rods of the triangular-shaped rod 62. The UV curing lamp 63 is spaced apart from the air inflation shaft 34 by 20 cm. After the gluing is completed, the paper tube will be moved to the position below the UV curing lamp 63 by the backshaping frame 31. Through the above structure, the UV curing lamp 63 can cure the glue on the surface of the paper tube, thereby speeding up the curing efficiency of the glue on the surface of the paper tube. At the same time, when the next paper tube is being glued, the next paper tube will drive the air inflation shaft 34 to rotate. The air inflation shaft 34 will drive the other air inflation shafts 34 to rotate through the driving belt 36, so that the paper tube at the UV curing lamp 63 will also be driven to rotate by the air inflation shaft 34, thereby enabling the glued paper tube to be uniformly irradiated by the UV curing lamp 63.

[0037] In use, each air inflation shaft 34 is connected to an external air source, the paper tube is sleeved outside the single air inflation shaft 34, the external air source corresponding to the single air inflation shaft 34 is started, the external air source inflates towards the inside of the air inflation shaft 34, the air inflation shaft 34 expands and fixes the paper tube, then the servo motor drives the screw rod two 35 to rotate, the screw rod two 35 drives the backshaping frame 31 to move along the top of the device body 1, the backshaping frame 31 drives the air inflation shaft 34 with the paper tube to move to the position above the glue roller 2 through the moving plate 32, and at the same time, the staff drives the motor to drive the glue roller 2 to rotate, the glue roller 2 drives the glue on the glue tank of the device body 1 to brush on the surface of the paper tube, and in this process, the rotation of the glue roller 2 drives the paper tube to rotate, and in this process, the paper tube also drives the air inflation shaft 34 to rotate, thereby enabling the glue roller 2 to brush the glue on the entire surface of the paper tube.

[0038] It should be noted that the air inflation shaft 34 is a prior art device for clamping pipe materials.

[0039] It should be further noted that the staff can adjust the height position of the moving plate 32 by rotating the screw rod one 33, so that the moving plate 32 drives the air inflation shaft 34 and the paper tube thereon to approach the glue roller 2, thereby facilitating the present protective device to perform the gluing operation on paper tubes with different diameters or thicknesses.

[0040] In the process of rotating the glue roller 2, the glue roller 2 drives the rotating wheel one 41 to rotate, and the rotating wheel one 41 drives the rotating wheel two 42 to rotate under the drive of the belt, the rotating wheel two 42 drives the sleeve 44 to rotate through the rotating rod 43, the sleeve 44 drives the spike rod 45 to rotate, and the spike rod 45 will burst the bubbles adhered to the surface of the glue roller 2 in the process of rotating, and after the bubbles are burst, the glue liquid on the surface of the glue roller 2 can be ensured to be smoother and more uniform, thereby improving the glue coating quality and making the glue coating layer more uniform. Meanwhile, the sleeve 44 will also drive the U-shaped rod 46 to rotate in the process of rotating, the U-shaped rod 46 rotates along the inside of the annular chute of the annular chute column 47, and under the limitation of the annular chute of the annular chute column 47, the U-shaped rod 46 will also move reciprocatingly along the outside of the rotating rod 43 while driving the sleeve 44 to rotate, the sleeve 44 drives the spike rod 45 to move, so that the spike rod 45 covers a wider surface area, improves the coverage range of the spike rod 45 for bursting bubbles, and avoids that the spike rod 45 is limited to a small range of working area; the rotating rod 43 also drives the elliptical groove disc 48 to rotate when rotating, and the elliptical groove of the elliptical groove disc 48 drives the Y-shaped frame 49 to drive the U-shaped carriage 410 to move reciprocatingly up and down along the inner wall of the liquid tank of the equipment main body 1. When the U-shaped carriage 410 moves upward each time, the U-shaped carriage 410 drives the swing plate 411 to move upward, and in this process, the top of the swing plate 411 will be subjected to the pushing force of the glue liquid, the blocking rod 412 will limit the downward movement track of the swing plate 411, and the swing plate 411 will not swing. At this time, the U-shaped carriage 410 drives the swing plate 411 to surge the glue liquid upward, so as to push the bubbles on the surface layer of the glue liquid away from the glue roller 2, thereby reducing the possibility of the bubbles adhering to the glue roller 2. When the U-shaped carriage 410 moves downward each time, in this process, the bottom of the swing plate 411 will be subjected to the pushing force of the glue liquid, and the swing plate 411 will be pushed upward by the glue liquid. At this time, the glue liquid will pass through the swing plate 411 and the U-shaped carriage 410, thereby avoiding the problem that the swing plate 411 will push the bubbles back when moving downward, causing the bubbles to adhere to the surface of the glue roller 2 again.

[0041] In the process of moving the back-shaped frame 31, the elastic telescopic rod 55 moves along. When the elastic telescopic rod 55 moves to the trapezoidal block slope of the U-shaped guide rod 54, the trapezoidal block slope of the U-shaped guide rod 54 pushes the telescopic end of the elastic telescopic rod 55 to compress, the telescopic end of the elastic telescopic rod 55 pushes the articulated rod 56 to drive the vertical plate 51 to move towards the air inflation shaft 34, the corresponding spring of the vertical plate 51 is stretched, and the vertical plate 51 drives the glue applying brush 53 to move towards the air inflation shaft 34 through the horizontal plate 52, so that the glue applying brush 53 contacts the outer wall of the paper tube. In the process of rotating the paper tube, the glue applying brush 53 can uniformly apply pressure to make the glue uniformly coated on the outer wall of the paper tube, avoiding the situation that the glue is unevenly applied or excessively concentrated in some areas. When the back-shaped frame 31 moves to switch to the next paper tube for glue applying operation, the corresponding elastic telescopic rod 55 of the previous paper tube moves out of the trapezoidal block of the U-shaped guide rod 54. At this time, the elastic telescopic rod 55 is reset under the action of the corresponding spring elastic force, the elastic telescopic rod 55 pulls the horizontal plate 52 through the articulated rod 56 to reset, and the horizontal plate 52 drives the glue applying brush 53 away from the paper tube.

[0042] It should be noted that, since the horizontal plate 52 and the vertical plate 51 are in sliding connection, the existence of the horizontal plate 52 does not interfere with the operation of the moving plate 32 when the moving plate 32 moves.

[0043] After the glue applying is completed, the paper tube is moved by the back-shaped frame 31 to a position below the UV curing lamp 63, and the staff starts the UV curing lamp 63. The UV curing lamp 63 performs curing operation on the glue on the surface of the paper tube, thereby accelerating the curing efficiency of the glue on the surface of the paper tube. When the next paper tube is rotating by the glue applying roller 2 for glue applying operation, the next paper tube synchronously drives the air inflation shaft 34 to rotate. The air inflation shaft 34 drives other air inflation shafts 34 to rotate through the driving belt 36, so that the paper tube at the UV curing lamp 63 is also driven to rotate by the air inflation shaft 34, thereby enabling the glued paper tube to be uniformly irradiated by the UV curing lamp 63.

[0044] It should be noted that, since the light intensity and uniformity of the UV curing lamp 63 depend to a great extent on the distance between the UV curing lamp 63 and the surface of the paper tube, in the process of driving the moving plate 32 to move by the screw rod 33, the moving plate 32 drives the UV curing lamp 63 and other devices to not move through the triangular rod 62, so that the distance between the UV curing lamp 63 and the air inflation shaft 34 is constant.

[0045] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
