An input roller group is fixedly installed at one end of the outer frame, and an output roller group is fixedly installed at the other end of the outer frame.

[0006] Furthermore: The outer contour of the limiting part is in a spiral shape, and the curvature from one end to the other end of the outer contour of the limiting part becomes larger and larger. A driving motor III is fixedly installed on the outer side wall of the bottom end of one fixing frame II.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 6 , in the embodiment of the present invention, an anti-rolling device for composite paper includes an outer frame 100. A upper driving assembly 300 is arranged at the top of the outer frame 100. The upper driving assembly 300 includes two fixing frames two 320. The fixing frames two 320 are fixedly connected to the top of the outer frame 100. The fixing frames two 320 are T-shaped. A round roller 330 is rotatably connected between the two ends of the top sides of the two fixing frames two 320. An eccentric roller 400 is rotatably connected between the bottoms of the two fixing frames two 320. The eccentric roller 400 includes a roller shaft 430 located inside. A limiting portion 420 is arranged on one side of the outer side wall of the eccentric roller 400. The limiting portion 420 is rotatably connected to the bottom of the fixing frame two 320. A first transmission belt 310 is connected in transmission between the eccentric roller 400 and the two round rollers 330. A lower driving assembly 200 is fixedly connected to the bottom of the outer frame 100. A second transmission belt 500 is connected in transmission around the lower driving assembly 200.

When the paper passes between the second transmission belt 500 and the first transmission belt 310, through the fit between the first transmission belt 310 and the bottom end of the eccentric roller 400, the top of the second transmission belt 500 is squeezed and fitted with the bottom of the first transmission belt 310, so as to squeeze and bend the passing paper, so that the paper bends downward, thereby offsetting and correcting the upward bend existing in the paper itself, making the paper straighter in the natural state, and reducing the transmission offset problem caused by the natural bend of the paper.

[0026] Embodiment 1

[0027] As Figures 3 to 6As shown, in this embodiment, the outer contour of the limiting part 420 is in a spiral shape, and the curvature from one end to the other end of the outer contour of the limiting part 420 becomes larger and larger. A driving motor three 800 is fixedly installed on the outer side wall of the bottom end of a fixing frame two 320. A transmission connection is provided between the output end of the driving motor three 800 and one end of a roller shaft 430. A lubricating belt 410 is slidably sleeved on the outer side wall of the eccentric roller 400. Lubricating oil is coated between the eccentric roller 400 and the lubricating belt 410. The outer side wall of the lubricating belt 410 is in contact with the inner side wall of the bottom end of the transmission belt one 310. A vertical groove 321 is formed in the middle position of the outer side wall of the fixing frame two 320. A gravity roller 350 is slidably connected between the inner walls of the two vertical grooves 321. The top end of the transmission belt one 310 passes under the gravity roller 350. One end of a fixing frame two 320 is fixedly connected to a driving motor two 340. A transmission connection is provided between the output end of the driving motor two 340 and one end of a round roller 330. The lower driving assembly 200 includes two fixing frames one 210. The fixing frames one 210 are fixedly connected to the outer frame 100. A transmission roller 220 is rotatably connected between one ends of the two fixing frames one 210. A driving motor one 250 is fixedly installed at one end of a fixing frame one 210. A transmission connection is provided between the output end of the driving motor one 250 and one end of the transmission roller 220. A horizontal groove 211 is formed in the outer side wall of the other end of the fixing frame one 210. A tensioning roller 230 is arranged between the other ends of the fixing frames one 210. Both ends of the tensioning roller 230 are rotatably connected to a sliding seat 231. The sliding seat 231 is slidably connected to the adjacent horizontal groove 211. A return spring 232 is fixedly connected between the inner wall of one end of the horizontal groove 211 and the sliding seat 231. An extrusion module 240 is arranged above the two fixing frames one 210. The extrusion module 240 includes two extrusion rollers 244 that can move up and down. The transmission roller 220, the tensioning roller 230, and the two extrusion rollers 244 are all in transmission connection with the inner side wall of the transmission belt two 500. The extrusion module 240 further includes a fixing plate 241. The fixing plate 241 is fixedly connected to the two fixing frames one 210. A U-shaped frame 243 is rotatably connected between both ends of the extrusion roller 244. Plug rods 245 are fixedly connected to both ends of the bottom side of the U-shaped frame 243. Sleeve tubes 242 are fixedly connected to the top surface of the fixing plate 241 corresponding to the positions of the four plug rods 245. Extrusion springs 246 are fixedly connected between the positions of both ends of the bottom surface of the U-shaped frame 243 and the top surface of the fixing plate 241.

[0028] In this embodiment, since the paper closer to the center in the paper roll is bent more severely, as the paper is unrolled, the degree of natural upward bending of the paper is greater. Through the spiral arrangement of the outer contour of the limiting part 420, it is convenient to adjust the angle of the eccentric roller 400 by the driving motor three 800 according to the bending degree of the paper, so that the parts with different curvatures of the limiting part 420 face between the two pressing rollers 244, realizing the adjustment of the downward bending degree when the paper passes between the first transmission belt 310 and the second transmission belt 500 as needed, so as to better correct the natural bending of the paper and prevent the subsequent paper from being rolled back. Through the setting of the gravity roller 350, the tension of the first transmission belt 310 is realized. The first transmission belt 310 is driven by driving the circular roller 330 to rotate by the driving motor two 340. Through the setting of the tensioning roller 230, the tension of the second transmission belt 500 is realized. Through the setting of the pressing spring 246, the pressing roller 244 is pressed upward, so that the part of the second transmission belt 500 between the two pressing rollers 244 can be closely attached to the bottom end of the first transmission belt 310, realizing the pressing of the paper, thereby correcting the bending of the paper. The paper is driven forward by the actively rotating first transmission belt 310 and the second transmission belt 500. Through the setting of the lubricating belt 410, when the first transmission belt 310 drives, the lubricating belt 410 is driven. The lubricating belt 410 slides with the eccentric roller 400 through lubricating oil, thereby reducing the friction between the first transmission belt 310 and the eccentric roller 400.

[0029] Embodiment Two

[0030] As Figure 7 shown, in this embodiment, the input roller group 600 includes two fixing frames three 610, and the fixing frames three 610 are fixedly connected to the outer frame 100. Guide rollers 630 are rotatably connected between the two ends of the top sides of the two fixing frames three 610. A hollow roller 620 that can move up and down is slidably connected between the middle positions of the two fixing frames three 610. The output roller group 700 has the same structure as the input roller group 600.

[0031] During specific implementation, after the eccentric roller 400 rotates, the part where the first transmission belt 310 and the second transmission belt 500 are in contact with each other moves up and down. Through the setting of the hollow roller 620, it is convenient for the paper to adapt to the left and right movement caused by the rotation of the eccentric roller 400. The hollow roller 620 limits the paper to reduce the shaking of the paper.
