Description

Technical Field

[0001] The utility model relates to the technical field of sheet paper production, in particular to a sheet paper deformation adjusting device for a sheet cutter. Background Art

[0002] At present, a sheet cutter is a device used to cut roll paper into single flat sheets. Since the shape of the roll paper has been determined in the papermaking process of the paper mill or the laminating process of the laminating machine, most printing plants require the roll paper to lie flat, and the flat sheets cut into single sheets are basically in a lying state. However, since some paper mills do not control the moisture content or back coating amount of the paper during the papermaking process or the laminating process of the laminating machine, the paper quality will be abnormal. The roll paper loses water seriously, resulting in the cutter cutting the roll paper into flat sheets. The resulting single flat sheets will warp and deform upwards, and thus cannot meet printing requirements.

[0003] In view of this, the present application provides a sheet paper deformation adjustment device for a sheet cutter to solve the technical problem of upward deformation of sheet paper in a sheet cutter. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a sheet paper deformation adjustment device for a cutting machine, comprising a rewinding roller, a paper cutting device, a twisting force rod and a first vertical plate and a second vertical plate arranged opposite to each other, wherein a triangular fixed plate, a first fixed rod and a second fixed rod are fixedly arranged horizontally and transversely between the first vertical plate and the second vertical plate, at least one through hole is opened on the fixed plate, and a lifting rod is movably connected in each through hole, a rack is fixedly provided on one side of the lifting rod, a rotating shaft is rotatably connected to the fixed plate, a gear meshing with the rack is fixed on the rotating shaft, and the twisting force rod is arranged horizontally and transversely and fixed to the lower end of the lifting rod.

[0005] In some embodiments, rollers are rotatably sleeved on both the first fixing rod and the second fixing rod.

[0006] In some embodiments, the twisting force rod is fixedly connected to the lifting rod by a fixing bolt.

[0007] In some embodiments, the first fixing rod and the second fixing rod are both fixed to the first vertical plate and the second vertical plate by fixing bolts.

[0008] In some embodiments, the fixing plate is fixed to the first vertical plate and the second vertical plate by fixing bolts.

[0009] In some embodiments, one end of the rotating shaft is connected to a rotating handwheel.

[0010] In some embodiments, one end of the rotating shaft is connected to a driving motor.

[0011] Compared with the prior art, the utility model provides a flat sheet deformation adjustment device for a sheet cutter, which adjusts the vertical position of the twisting force rod through a spiral rod, and then the paper wrapped around the first fixed rod, the twisting force rod and the second fixed rod has different twisting forces on the paper as the vertical positions of the twisting force rods change, thereby achieving effective adjustment of paper deformation, so that the paper coming out of the paper cutting device is in a flat state after being cut. The device has the characteristics of simple structure, low cost and high working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See also Figures 1-4 As shown, an embodiment of the present application provides a sheet deformation adjustment device for a cutting machine, comprising a rewinding roller 1, a paper cutting device 2, a twisting force rod 3, and a first vertical plate 4 and a second vertical plate 5 arranged opposite to each other, wherein a triangular fixing plate 6, a first fixing rod 7 and a second fixing rod 8 are fixedly arranged horizontally and transversely between the first vertical plate 4 and the second vertical plate 5, and at least one through hole is provided on the fixing plate 6, and a lifting rod 9 is movably connected in each through hole, a rack 91 is fixedly provided on one side of the lifting rod 9, a rotating shaft 61 is rotatably connected to the fixing plate 6, and a gear 62 meshing with the rack 91 is fixed on the rotating shaft 61, and the twisting force rod 3 is arranged horizontally and transversely and fixed to the lower end of the lifting rod 9.

[0022] In the above embodiment, the positions of the first vertical plate 4 and the second vertical plate 5 can be interchanged, and the positions of the first fixing rod 7 and the second fixing rod 8 can be interchanged.

[0023] In the above embodiment, since the fixed plate 6 is horizontally disposed between the first fixed rod 7 and the second fixed rod 8 and forms a triangular structure with the first fixed rod 7 and the second fixed rod 8, and the lifting rod 9 is meshed and connected with the gear 62 provided on the fixed plate 6 via the rack 91, the lifting rod 9 can be driven to rise and fall vertically by the rotation of the gear 62. At this time, the twisting force rod 3 fixedly connected to the lower end of the lifting rod 9 can rise and fall vertically with the lifting rod 9, thereby achieving the position adjustment of the twisting force rod 3 in the vertical direction. Since the twisting force rods 9 in different vertical positions exert different twisting forces on the paper 11, the vertical position of the twisting force rod 9 can be adjusted according to the degree of upward deformation of the paper 11 to effectively adjust the deformation degree of the paper 11. Therefore, the device provided by the present application has the characteristics of simple structure, low cost and high working efficiency.

[0024] See Figure 3 As shown, in some embodiments, a roller shaft 10 is rotatably sleeved on both the first fixing rod 7 and the second fixing rod 8 .

[0025] In this embodiment, by rotatably sleeved on the first fixed rod 7 and the second fixed rod 8, the paper 11 wrapped around the first fixed rod 7 and the second fixed rod 8 can drive the roller 10 to roll, thereby effectively reducing the friction between the paper 11 and the first fixed rod 7 and the second fixed rod 8, and reducing the probability of accidents such as the paper 11 breaking.

[0026] In some embodiments, the twisting force rod 3 is fixedly connected to the lifting rod 9 by fixing bolts.

[0027] In the above embodiment, the twisting force rod 3 is fixedly connected to the lower ends of at least two lifting rods 9 by fixing bolts, thereby ensuring the stability of the connection between the twisting force rod 3 and the lifting rod 9. In other embodiments, other fixed connection methods may also be used, such as welding, riveting, etc.

[0028] In some embodiments, the first fixing rod 7 and the second fixing rod 8 are fixed to the first vertical plate 4 and the second vertical plate 5 by fixing bolts, and the fixing plate 6 is fixed to the first vertical plate 4 and the second vertical plate 5 by fixing bolts.

[0029] In the above embodiment, the fixing plate 6, the first fixing rod 7 and the second fixing rod 8 are fixed to the first vertical plate 4 and the second vertical plate 5 by fixing bolts, which effectively ensures the stability of the fixing plate 6, the first fixing rod 7 and the second fixing rod 8, and provides a guarantee for the deformation adjustment of the flat paper.

[0030] In some embodiments, one end of the rotating shaft 61 is connected to a rotating handwheel 63 .

[0031] In the above embodiment, a rotating handwheel 63 for rotating the rotating shaft 61 is provided at one end of the rotating shaft 61, thereby greatly facilitating the operator's operation of the rotating shaft 61. The gear 62 on the rotating shaft 61 drives the rack 61 to vertically rise and fall, effectively improving the efficiency of adjusting the vertical position of the twisting force rod 3. It should be noted that when the rotating handwheel 63 is provided at one end of the rotating shaft 61, it should be understood that a stopper should be provided on the fixed plate 6 to limit the rotation of the rotating shaft 61, ensuring that the lifting rod 9 does not rise or fall due to the rotation of the rotating shaft 61 itself.

[0032] In some embodiments, one end of the rotating shaft 61 is connected to a driving motor (not shown in the figure).

[0033] In the above embodiment, by connecting a drive motor to one end of the rotating shaft 61, the driving motor drives the rotating shaft 61 to rotate to drive the gear 62 to rotate, which can not only reduce the labor intensity of the operator, but also improve the adjustment accuracy of the vertical position of the torsion force rod 3.

This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are intended only to facilitate understanding of the core concept of the present invention.
