Description

Technical Field

[0001] The utility model relates to a transfer cardboard edge trimming machine capable of preventing deviation. Background Art

[0002] Transfer paper is a paper material widely used in the printing and packaging industry.

DETAILED DESCRIPTION

[0024] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0025] like Figure 1-Figure 5 As shown, the transfer paper cutting machine for preventing deviation provided by the present embodiment comprises a workbench 1, input rollers 2 and output rollers 3 are respectively arranged on both sides of the workbench 1, an anti-deflection guide plate 4 is arranged between the input roller 2 and the output roller 3, and limiting vertical plates 5 are arranged on both sides of the anti-deflection guide plate 4 to ensure that the transfer paper keeps the correct position during the transportation process, reduce deviation, and improve the cutting accuracy, and a center pressure roller 6 and a trimming knife 7 are respectively arranged at both ends of the anti-deflection guide plate 4, and an edge pressure wheel 8 is arranged between the center pressure roller 6 and the trimming knife 7. The center pressure roller 6 and the edge pressure wheel 8 ensure that the transfer paper is tightly attached to the anti-deflection guide plate 4 by applying uniform downward pressure to the transfer paper, thereby avoiding warping and deviation, thereby ensuring the smoothness of the cutting process.

[0026] The cutting process of the transfer paper is as follows: first, it passes through the input roller 2 and enters the anti-deflection guide 4, and the position of both sides of the transfer paper is limited by the limit plate 5, and then it is pressed on the anti-deflection guide 4 by the center pressure roller 6 and the edge pressure wheel 8 in turn, and then the edge is cut off by the trimming knife 7, and finally it goes out through the output roller 3 to complete the cutting operation.

[0027] In this embodiment, if Figure 1 As shown, a support frame 9 is arranged above the anti-deflection guide plate 4, a hanger 10 is arranged between the support frame 9 and the center pressure roller 6, both ends of the center pressure roller 6 are connected to the hanger 10, and a cylinder 11 is arranged above the support frame 9. The piston rod of the cylinder 11 extends downward from the support frame 9 and is connected to the hanger 10. The distance between the hanger 10 and the center pressure roller 6 and the anti-deflection guide plate 4 is controlled by the cylinder 11, so that transfer cardboard of different thicknesses can be compressed, which increases the adaptability and flexibility of the machine.

[0028] In this embodiment, if Figure 1 As shown, a first telescopic rod 12 is provided between the hanger 10 and the support frame 9 on both sides of the cylinder 11, which provides additional stability and ensures that the adjustment process is carried out stably.

[0029] In this embodiment, if Figure 4 As shown, two knife grooves 13 are arranged on the anti-deflection guide plate 4 along its length direction at intervals, and two edge cutting knives 7 are arranged. The two edge cutting knives 7 are respectively arranged above the two knife grooves 13 to prevent the edge cutting knives 7 from scratching the surface of the anti-deflection guide plate 4 and affecting the edge cutting of the transferred jammed paper.

[0030] In this embodiment, if Figure 4 and Figure 5As shown, a slide groove 14 is provided on the inner side of the limiting vertical plate 5 along its height direction, a slider 15 is provided on the side of the edge pressing wheel 8 close to the limiting vertical plate 5, a fixed plate 16 is horizontally provided on the inner side of the limiting vertical plate 5, a connecting block 17 is provided on the other side of the edge pressing wheel 8, a second telescopic rod 18 is provided between the fixed plate 16 and the connecting block 17, a spring 19 is provided on the outer side of the second telescopic rod 18, when the transfer paper is not cut, the bottom of the edge pressing wheel 8 is attached to the anti-deflection guide plate 4, when cutting, the transfer paper will be inserted between the anti-deflection guide plate 4 and the edge pressing wheel 8, the second telescopic rod 18 and the spring 19 will shrink according to the thickness of the transfer paper, and the slider 15 will also slide upward, so that the edge pressing wheel 8 can press the transfer paper of different thicknesses.

[0031] In this embodiment, if Figure 2 As shown, two edge pressing wheels 8 are provided, and the two edge pressing wheels 8 are respectively arranged on the inner sides of the two limiting vertical plates 5, so as to further ensure the smooth movement of the jammed paper during the cutting process and avoid deviation and distortion.

[0032] In this embodiment, if Figure 1 As shown, an input motor 20 is provided on one side of the input roller 2, and an output motor 21 is provided on one side of the output roller 3, so that the transfer jam can move normally.

[0033] In summary, in this embodiment, the anti-deflection guide plate 4 and the limiting vertical plates 5 on both sides thereof effectively prevent the transfer paper jam from deflecting during the conveying process, ensuring that the transfer paper jam moves smoothly along the predetermined path, thereby improving the cutting accuracy. At the same time, the setting of the center pressure roller 6 and the edge pressure roller 8 applies pressure to the transfer paper jam from the center and both sides respectively, so that the transfer paper jam is close to the anti-deflection guide plate 4, further reducing the movement and warping of the transfer paper jam during the cutting process, and ensuring the straightness and smoothness of the cutting edge. This design not only optimizes the conveying and positioning process of the transfer paper jam, but also significantly improves the cutting quality, ensuring that the edges of the final product are neat and error-free, and improving production efficiency and product quality.
