[0002] The reel paper cutting machine is a kind of equipment specially used to cut large reel paper into required specification paper roll, is widely used in papermaking industry and printing industry.This kind of machine passes through high -efficient cutting technique, ensures the accuracy and quality of paper, satisfies the demand of different industries
[0003] When reel paper is cut, paper curvature influences, paper jam may occur when cutting due to uneven paper, and the cut flat paper is bent, which affects work efficiency and paper product effect, so it is necessary to improve. UTILITY MODEL CONTENT
[0004] The utility model provides a kind of paper cutting's reverse bending device that can effectively solve the phenomenon that paper is jammed or the flat paper cut is bent due to the curvature of paper when cutting, ensure work efficiency and product quality;Solve the technical problems that the edge of the reel paper is bent due to the curvature of paper itself when cutting in the prior art, which leads to paper jamming when cutting, and the cut flat paper is also prone to bending, which affects work efficiency and product quality.
[0005] The above technical problems of the utility model are solved by the following technical scheme: a kind of paper cutting's reverse bending device, including original paper roll and cutter, be equipped with several guide rollers on the path between original paper roll and cutter, paper is cut along guide roller to cutter, several groups of reverse bending devices are equipped on the path between original paper roll and cutter, and the reverse bending device is used to adjust the bending degree of both sides of paper. Paper is cut along guide roller to cutter after being led out from original paper roll, but due to the influence of natural curvature of paper, both sides will be bent and rolled, causing paper jamming or the flat paper cut is bent, and the reverse bending device can bend both sides of paper in opposite directions, which can effectively ensure the flatness of paper, without paper jamming, and the flat paper cut is also flat.
[0006] As preferred, the reverse bending device includes adjusting worm gear and adjusting roller arranged on original paper conveying path, and the adjusting worm gear drives the adjusting roller to adjust the position pressed on paper through connecting piece. When adjusting worm gear rotates, adjusting roller will swing around shaft direction, and adjusting roller will be pressed on both sides of paper to a certain extent, so that paper is bent in opposite directions.
[0007] As preferred, the connecting piece is rocker arm or connecting sheet. Adjusting roller can be installed on adjusting worm gear through rocker arm or connecting sheet, and the utility model is illustrated by fan-shaped connecting sheet, and adjusting roller is driven to rotate and adjust by adjusting worm gear and connecting sheet.
[0008] As preferred, the reverse bending device further comprises an adjusting worm gear arranged on the side of the adjusting worm wheel, and the adjusting worm wheel is in meshing transmission with the adjusting worm gear.
[0009] As preferred, one end of the adjusting worm gear is fixedly provided with a rocker.
[0010] As preferred, each group of the reverse bending device comprises two adjusting worm gears and an adjusting worm gear, which are arranged on the two sides of the paper respectively, and the two adjusting rollers press on the two sides of the paper to adjust the bending degree.
[0011] As preferred, the bending direction of the paper is opposite to the natural bending direction of the paper.
[0012] As preferred, a plurality of driving rollers are arranged on the side of the paper roll conveying path close to the discharging end, and the driving rollers are clamped on the upper and lower surfaces of the paper to drive the paper conveying.
[0013] Therefore, the reverse bending device for paper cutting has the following advantages: it can effectively solve the problems of easy damage, oil leakage and smoke leakage of the hose connected to the smoke exhaust pipe, affect the health and safety of production, and can adapt to the movement and adjustment of the film head of the film laminating machine, and optimize the production environment. BRIEF DESCRIPTION OF DRAWINGS
[0014] Figure 1 It is a front view structural schematic diagram of the reverse bending device for paper cutting.
[0015] In the figure, the original paper roll 1, the cutter 2, the guide roller 3, the driving roller 4, the adjusting worm gear 5, the connecting plate 6, the adjusting roller 7, the adjusting worm gear 8, and the rocker 9. DETAILED DESCRIPTION
[0016] The technical solutions of the utility model will be further specifically described below by means of embodiments and in combination with the drawings.
[0017] Embodiment:
[0018] As shown in the figure, a reverse bending device for paper cutting comprises an original paper roll 1 and a cutter 2. Figure 1 A plurality of guide rollers 3 are arranged on the conveying path between the original paper roll 1 and the cutter 2, and the paper is conveyed along the guide rollers 3 to the cutter 2 for cutting.
