DETAILED DESCRIPTION

[0024] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0025] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0026] The connection method can be bonding, welding, bolt connection and other existing methods, depending on actual needs.

[0027] like Figures 1 to 5 A paper product production pattern printing device shown in the figure includes a workbench 1, and bases can be symmetrically installed on the two side surfaces of the workbench 1. Hydraulic columns 2 are provided on both sides of the workbench 1, and the two hydraulic columns 2 are respectively installed on the top surfaces of the two bases, so that after the workbench 1 is moved to the work location, the two hydraulic columns 2 can also move synchronously.

[0028] The top surfaces of the two hydraulic columns 2 are fixedly connected with a transverse plate 3, which is laterally arranged above the workbench 1. Four connecting plates 4 are symmetrically installed on the two sides of the transverse plate 3, wherein the lengths of two connecting plates 4 are smaller than the lengths of the other two connecting plates 4, and the bottom surface of each connecting plate 4 is fixedly connected with a rectangular block 5. Since the length between two connecting plates 4 is different from the length of the other two connecting plates 4, the distance between two rectangular blocks 5 is also smaller than the distance between the other two rectangular blocks 5. A torsion spring 6 is connected to the side of each rectangular block 5 away from the transverse plate 3, and the free end of each torsion spring 6 is fixedly connected with an active The movable rod 7 is provided with a tilted arrangement, wherein the distance between the two movable rods 7 is smaller than the distance between the other two movable rods 7, so that the two movable rods 7 with a smaller distance between them are located between the two movable rods 7 with a larger distance between them, that is, each two movable rods 7 are arranged crosswise, and the movable rod 7 can rotate with the torsion spring 6 as the axis, and the torsion spring 6 is set as the existing structure, and it is only necessary to allow the movable rod 7 to return to its original position after being rotated, and a side opposite to each of the two movable rods 7 and away from the torsion spring 6 is rotatably connected with a pressing roller 8 for flattening the paper product, and the length of one pressing roller 8 is longer than the other The length of a pressing roller 8 is one, and the two pressing rollers 8 are in the same horizontal plane. After the paper product is placed on the top surface of the workbench 1, the hydraulic column 2 is turned on to allow the hydraulic column 2 to drive the cross plate 3 to move downward. When the cross plate 3 moves downward, it will drive the four connecting plates 4 and the four rectangular blocks 5 to move downward, so that the four rectangular blocks 5 all drive the movable rods 7 to move downward through the torsion springs 6, and the four movable rods 7 can drive the two pressing rollers 8 to press against the top surface of the paper product. At this time, the cross plate 3 continues to move downward, and through the inclined setting of each movable rod 7, each movable rod 7 is gradually moved by the downward force of the cross plate 3 and the restriction of the pressing roller 8 against the paper product. It is in an inclined state, so that each two movable rods 7 can drive the pressure roller 8 to move on the top surface of the paper product when they are gradually inclined. Since each movable rod 7 is cross-arranged, the two pressure rollers 8 can move in opposite directions on the top surface of the paper product, so that the two pressure rollers 8 can level the wrinkled paper products, which is convenient for subsequent printing and avoids the incomplete printing of patterns when the wrinkled paper products are printed, thereby improving the quality of printing on the paper products. After printing is completed, the cross plate 3 moves upward, and the movable rod 7 can be driven to return to its original position through the torsion spring 6, so that the two pressure rollers 8 are close to each other, which is convenient for leveling the paper products next time.

[0029] A limit block 9 for limiting the movable rod 7 is fixedly connected to the upper half of each rectangular block 5 facing one side of the movable rod 7. Each limit block 9 is respectively against four movable rods 7 to ensure that the movable rod 7 is always in a tilted state.

[0030] A cylinder 10 is fixedly installed on the top surface of the horizontal plate 3, and the piston rod of the cylinder 10 passes through the horizontal plate 3 and is fixedly connected to a printing press body 11. When the wrinkled paper product is flattened, the printing press body 11 is driven downward by the cylinder 10 to print the paper product. The length of each movable rod 7 and the size of the printing press body 11 can be selected according to actual conditions. It is only necessary that the distance between the two pressure rollers 8 after the paper product is flattened is sufficient for the printing press body 11 to pass through, so as to avoid the two pressure rollers 8 hindering the movement of the printing press body 11.

[0031] A placement plate 12 for placing paper products is installed on the top surface of the workbench 1. The paper products to be printed can be placed on the top surface of the placement plate 12. A transverse groove 13 is horizontally opened on one side of the placement plate 12. The inner walls of both sides of the transverse groove 13 are rotatably connected with threaded rods 14. The two ends of the threaded rod 14 are processed with threaded teeth in opposite directions. One end of the threaded rod 14 passes through the placement plate 12 and is fixedly connected with a turning handle to facilitate the rotation of the threaded rod 14. The threaded sleeve on the peripheral side of the threaded rod 14 is provided with a movable block 15. The top surfaces of the two movable blocks 15 are fixedly connected with limit rods 16 for limiting the position of the pressure roller 8. The limit rod 16 The bottom surface of is in contact with the top surface of the placement plate 12. After the paper product is placed on the top surface of the placement plate 12, the handle is turned, and the handle drives the threaded rod 14 to rotate, so that the threaded rod 14 drives the two movable blocks 15 to move in relative or opposite directions, and the two movable blocks 15 can respectively drive the two limit rods 16 to move, so that the distance between the two limit rods 16 is adapted to the length of the paper product to be printed. When the two pressing rollers 8 move along the paper product, the pressing roller 8 will move to one side of the limit rod 16, so that the limit rod 16 can limit the position of the pressing roller 8, so that the pressing roller 8 can press the paper product for convenient printing.

[0032] In special cases, such as when the distance between the two pressure rollers 8 is not enough for the printer body 11 to pass through, the cross plate 3 can continue to move downward, allowing the two pressure rollers 8 to continue to move in opposite directions, and the two limit rods 16 will also move to ensure that the distance between the two pressure rollers 8 is sufficient for the printer body 11 to pass through.

[0033] Working principle:

[0034] The paper product production pattern printing device places the paper product to be printed on the surface of the placement plate 12, and at this time, the hydraulic column 2 is turned on to allow the hydraulic column 2 to drive the cross plate 3 to move downward, so that the cross plate 3 drives the four movable rods 7 to move downward through the four connecting plates 4 and the four rectangular blocks 5, so that the four movable rods 7 can drive the two pressure rollers 8 to press against the surface of the paper product. Due to the setting of the limit block 9, the movable rod 7 will be in an inclined state. At this time, the cross plate 3 continues to move downward, allowing the movable rod 7 to rotate through the torsion spring 6, and then gradually tilt, so that the gradually inclined movable rod 7 can drive the pressure roller 8 to move on the top surface of the paper product. Since the four movable rods 7 are cross-arranged, the two pressure rollers 8 will move in opposite directions, and then the two pressure rollers 8 can move on the surface of the paper product, so that the two pressure rollers 8 can flatten the wrinkled paper product. At this time, the cylinder 10 is turned on, so that the cylinder 10 can drive the printing machine body 11 to move downward and fit the paper product, and print the paper product, which can avoid the wrinkles of the paper product and the incomplete printing, thereby improving the quality of printing on the paper product.
