The gantry frame is slidably mounted on the machine base and driven to slide by the first drive assembly. The mounting frame is mounted on the gantry frame. The adjustment assembly includes a drive motor, a double-ended lead screw, a pair of sliding seats, and a pair of sliding guide rails. The threads on the two ends of the double-ended lead screw are in opposite directions. The two sliding seats are slidably mounted on the sliding guide rails and are threadedly connected to the two ends of the double-ended lead screw, respectively. The drive cylinder is fixedly mounted on the mounting frame, and a support sleeve is fixedly mounted on the telescopic rod of the drive cylinder. The cutting assembly includes a mounting rod, a cutter, and a support rod. One end of the mounting rod is hinged to the sliding seat, and the cutter is mounted on the other end of the mounting rod. One end of the support rod is fixed to the mounting rod, and the other end of the support rod slides through the support sleeve.

[0006] Preferably, the cutting assembly further includes a cutting cylinder and a cutting frame. The mounting rod is arc-shaped and the end away from the sliding seat is bent downward. The cutting cylinder is fixedly mounted on the support rod. The cutting frame is slidably mounted on the mounting rod and fixed to the telescopic rod of the cutting cylinder. The cutter is vertically rotatably mounted on the cutting frame.

[0007] Preferably, a movable groove is provided through the length of the mounting rod, and a sliding rod is fixedly provided on one side of the cutting frame, the sliding rod passing through the movable groove.

[0008] Preferably, the sliding rod is configured as a bolt, which passes through the movable groove and is threaded onto one side of the cutting frame.

[0009] Preferably, an extension rod is horizontally fixed on one side of the cutting frame, a pressure roller frame is raised and lowered on the extension rod, a spring is provided between the pressure roller frame and the extension rod, a pressure roller is rotatably mounted on the pressure roller frame, and the pressure roller abuts against the surface of the printing paper under the action of the spring.

[0027] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer and more understandable, the following description is provided in conjunction with the appendix. Figure 1-8 The present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0028] Reference Figure 1 , Figure 2 and Figure 3A paper cutting device for printing includes a machine base 1, a gantry frame 2, a first drive assembly 3, a mounting frame 4, an adjusting assembly 5, a drive cylinder 6, and a pair of cutting components 7. The gantry frame 2 is slidably mounted on the machine base 1. The first drive assembly 3 is located on both sides of the machine base 1 and drives the gantry frame 2 to slide on the machine base 1. The mounting frame 4 is horizontally slidably mounted on the gantry frame 2, and a second drive assembly 21 is provided on the gantry frame 2 to drive the mounting frame 4 to slide horizontally on the gantry frame 2. The adjusting assembly 5 and the drive cylinder 6 are both located on the mounting frame 4. The drive cylinder 6 supports the cutting components 7 and drives the cutting components 7 to rotate along the mounting frame 4. The adjusting assembly 5 adjusts the distance between the two cutting components 7.

[0029] A cutting platform 11 is fixedly installed on the machine base 1. The cutting platform 11 is rectangular and located below the gantry frame 2. Several limiting rods 12 are vertically fixed on the adjacent two sides of the cutting platform 11, and the limiting rods 12 are evenly distributed along the sides of the cutting platform 11. Stacks of printed cards are placed on the cutting platform 11, so that the two sides of the stacked printed cards abut against the limiting rods 12 on the cutting platform 11.

[0030] Reference Figure 4 The adjusting assembly 5 is configured to include a drive motor 51, a double-ended lead screw 52, ​​a pair of sliding seats 53, and a pair of sliding guide rails 54. The two sliding guide rails 54 are horizontally fixed on both sides of the mounting frame 4. The threads at both ends of the double-ended lead screw 52 are opposite in direction. The two sliding seats 53 are slidably mounted on the sliding guide rails 54 on both sides of the mounting frame 4, with the two sides of the double-ended lead screw 52 threadedly connected to the two sliding seats 53 respectively. The drive motor 51 drives the double-ended lead screw 52 to rotate, causing the two sliding seats 53 to move closer to or further away from each other, thereby adjusting the distance between the two sliding seats 53. This ensures that the adjusted distance meets the requirements for the predetermined width of the printing paper. The second drive assembly 21 drives the mounting frame 4 to move on the gantry 2, so that both cutting assemblies 7 are located above the printing paper.

[0031] Reference Figure 5 , Figure 6 and Figure 7The cutting assembly 7 includes mounting rods 71, a cutter 72, a support rod 73, a cutting cylinder 74, and a cutting frame 75. One end of the mounting rods 71 ​​of the two cutting assemblies 7 is hinged to two sliding seats 53 respectively, and one end of the support rod 73 is fixed to the middle part of the mounting rod 71, so that the support rod 73 and the mounting rod 71 form a "T" shape structure, and the support rods 73 fixed to the two mounting rods 71 ​​are arranged facing each other. In addition, a drive cylinder 6 is fixedly installed on the mounting frame 4, and a support sleeve 61 is fixedly installed on the telescopic rod of the drive cylinder 6, so that the support rods 73 fixed to the two mounting rods 71 ​​are all inserted into the support sleeve 61, and the support rods 73 and the support sleeve 61 are slidably connected, with the support sleeve 61 providing support for the support rods 73 and the mounting rods 71.

[0032] The mounting rod 71 is arc-shaped, with the end of the mounting rod 71 away from the sliding seat 53 bent downwards. The cutting frame 75 is slidably mounted on the mounting rod 71, and the cutting cylinder 74 is fixedly mounted on the support rod 73. The telescopic rod of the cutting cylinder 74 is fixed to the cutting frame 75, and the cutting cylinder 74 drives the cutting frame 75 to slide on the mounting rod 71. For this purpose, a movable groove 711 is formed along the length of the mounting rod 71. Correspondingly, a sliding rod 76 is fixedly mounted on one side of the cutting frame 75, and the sliding rod 76 passes through the movable groove 711 of the mounting rod 71. For ease of installation, the sliding rod 76 is a bolt. During installation, the bolt passes through the movable groove 711 and is threadedly connected to the cutting frame 75. The cutter 72 is vertically mounted on the cutting frame 75. The extension rod of the drive cylinder 6 extends, thereby driving the mounting rod 71 to rotate around the sliding seat 53 to a suitable position. Then the extension rod of the cutting cylinder 74 extends, thereby driving the cutting frame 75 and the cutter 72 to slide down along the mounting rod 71, so that the cutter 72 cuts the printing paper.

[0033] Reference Figure 7 and Figure 8To prevent the printing paper from shifting during the cutting process of the cutter 72, the extension rod of the drive cylinder 6 extends, causing the mounting rod 71 to rotate around the sliding seat 53 under the connection of the support sleeve 61 and the support rod 73. An extension rod 77 is horizontally fixed on one side of the cutting frame 75, and a pressure roller frame 78 is raised and lowered at the bottom of the extension rod 77. The pressure roller frame 78 is used to rotate and install the pressure roller 8. For this purpose, a spring 9 is provided between the extension rod 77 and the pressure roller frame 78, and a guide bolt 79 is provided at the bottom of the extension rod 77. A guide hole 781 is formed in the pressure roller frame 78. The guide bolt 79 is passed through the guide hole 781 and the spring 9 in sequence, and the guide bolt 79 is threaded to the bottom of the extension rod 77, so that the two ends of the spring 9 abut against the extension rod 77 and the head of the guide bolt 79, respectively. To ensure the pressure roller frame 78 remains stable during lifting and lowering, a groove 782 is formed on one side of the pressure roller frame 78, and the end of the extension rod 77 away from the cutting frame 75 is engaged in the groove 782 of the pressure roller frame 78. This allows the pressure roller frame 78 to move along the guide bolt 79 and the end of the extension rod 77 during lifting and lowering.

[0034] The drive cylinder 6 drives the mounting rod 71 and support rod 73 to adjust to a suitable height. The cutting cylinder 74 drives the cutting frame 75 to move downward along the mounting rod 71 until the pressure roller 8 abuts against the surface of the printing paper. The spring 9 allows the pressure roller 8 to have a certain amount of vertical play. When cutting printing papers of different thicknesses, the pressure roller 8 can maintain contact with the surface of the printing paper under the action of the spring 9. The first drive assembly 3 drives the gantry 2 to move on the machine base 1 to cut the printing paper stacked on the cutting platform 11.

[0035] The specific implementation principle of this application embodiment is as follows: When it is necessary to use the cutting equipment to cut printing paper so that the width of the cut printing paper meets the usage requirements, the printing paper to be cut is stacked on the cutting platform 11, so that two sides of the printing paper abut against each limiting rod 12. Then, the drive motor 51 drives the double-headed lead screw 52 to rotate, thereby driving the two sliding seats 53 to move, so that the cutters 72 of the two cutting components 7 maintain a suitable distance. And the second drive component 21 drives the mounting frame 4 to move on the gantry 2, so that both cutting components 7 are located in the area above the printing paper. The extension rod of the drive cylinder 6 is retracted, thereby causing the ends of the two mounting rods 71 ​​away from the sliding seats 53 to descend to a suitable height.

[0036] The telescopic rod of the cutting cylinder 74 extends, causing the cutting frame 75 and the cutter 72 to slide along the length of the mounting rod 71, so that the bottom of the cutter 72 is slightly lower than the surface of the cutting platform 11. Finally, the first drive assembly 3 drives the gantry 2 to move on the machine base 1, causing the cutter 72 and the pressure roller 8 to move towards the upper limit rod 12 of the cutting platform 11. During the movement of the gantry 2, the pressure roller 8 rolls against the surface of the printing paper to press the stacked printing paper. The spring 9 between the pressure roller frame 78 and the extension rod 77 provides the pressure roller 8 with play space, so that the pressure roller 8 can adapt when pressing the stacked printing paper of different thicknesses. At the same time, the gantry 2 moves so that the two cutters 72 cut the printing paper so that the width of the cut printing paper meets the usage requirements. During the cutting process, the limit rod 12 on the cutting platform 11 limits the printing paper. The cutting device allows for adjustment of the distance between the two cutters 72, thus meeting the width requirements of the printed paper after cutting and adapting to the cutting needs of printed paper with different widths.

[0037] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, shall be protected by the present invention.
