[0010] Furthermore, the sliding structure includes a top plate connected to the top of the support frame, a longitudinal slide rail provided on the top plate, a longitudinal slider connected to the longitudinal slide rail, and a longitudinal drive structure connected to the longitudinal slider for driving the longitudinal slider to move; a transverse slide rail connected to the longitudinal slider, a transverse slider connected to the transverse slide rail, and a transverse drive structure connected to the transverse slider for driving the transverse slider to move; a rotating structure connected to the transverse slider, and the cutting structure connected to the rotating structure.

[0011] The sliding structure allows the cutting mechanism to move both vertically and horizontally. During use, the operator can adjust the position of the cutting mechanism according to the requirements of the paper to be cut.

[0012] Furthermore, the lateral drive structure includes a screw connected to the lateral slider, and a first motor connected to the screw to drive the screw to rotate in the forward or reverse direction; the longitudinal drive structure includes a third electric telescopic rod connected to the longitudinal slider.

[0013] The first motor is a reversible motor, meaning it can drive the screw to rotate clockwise or counterclockwise.

[0037] Example 1

[0038] like Figures 1-6 As shown, this embodiment provides a paper cutting structure, including a paper placement plate 14, on which multiple longitudinal cutting grooves 13 and transverse cutting grooves 22 are spaced apart; the paper placement plate 14 is mounted on a support frame 01, and a fixing structure for fixing the paper is connected to the support frame 01; a cutting structure is connected to the support frame 01 at the top of the paper placement plate 14, and the cutting structure is slidably connected to the top of the support frame 01 through a sliding structure; a rotating structure for driving the cutting structure to rotate is connected to the cutting structure.

[0039] Specifically, the fixing structure includes a telescopic structure connected to the support frame 01 on both sides of the paper placement plate 14, and a first pressing structure is connected to the telescopic structure. The telescopic structure includes a first electric telescopic rod 02, and the first pressing structure includes a push block 03 with an inverted L-shaped cross-section connected to the first electric telescopic rod 02. The top of the push block 03 is provided with a through groove 23, and a second electric telescopic rod 05 is connected to the push block 03. The telescopic end of the second electric telescopic rod 05 passes through the through groove 23 and is connected to the first pressing plate 04.

[0040] After the worker places the paper to be cut on the paper placement plate 14, it needs to be secured for subsequent cutting. First, the inverted L-shaped push block 03 is pushed forward to contact the paper using the first electric telescopic rod 02. The first electric telescopic rods 02 on both sides are activated simultaneously, so that the push blocks 03 on both sides contact the paper at the same time. If there is any misalignment of the paper, it can be aligned by the vertical plate of the push block 03. After the paper is aligned, the second electric telescopic rod 05 is activated. The extension of the second electric telescopic rod 05 pushes the first pressing plate 04 downward, thereby pressing and fixing the two sides of the paper.

[0041] Specifically, the sliding structure includes a top plate 21 connected to the top of the support frame 01, a longitudinal slide rail 20 provided on the top plate 21, a longitudinal slider 08 connected to the longitudinal slide rail 20, a longitudinal drive structure connected to the longitudinal slider 08 to drive the longitudinal slider 08 to move; a transverse slide rail 06 connected to the longitudinal slider 08, a transverse slider 09 connected to the transverse slide rail 06, a transverse drive structure connected to the transverse slider 09 to drive the transverse slider 09 to move; a rotating structure connected to the transverse slider 09, and a cutting structure connected to the rotating structure.

[0042] The lateral drive structure includes a screw 07 connected to the lateral slider 09, and a first motor 12 connected to the screw 07 to drive the screw 07 to rotate in either the forward or reverse direction; the longitudinal drive structure includes a third electric telescopic rod connected to the longitudinal slider 08. The first motor 12 is a reversible motor, meaning it can drive the screw 07 to rotate clockwise or counterclockwise.

[0043] When the longitudinal position of the cutting structure needs to be adjusted, the transverse drive structure remains stationary, and the third electric telescopic rod is activated. The extension of the third electric telescopic rod pushes the longitudinal slider 08 to move on the longitudinal slide rail 20, thereby adjusting the longitudinal position of the cutting structure. When the transverse position of the cutting structure needs to be adjusted, the longitudinal drive structure remains stationary, and the first motor 12 is activated. The forward rotation of the first motor 12 moves the transverse slider 09 to the left, and the reverse rotation of the first motor 12 moves the transverse slider 09 to the right, thereby adjusting the horizontal position of the transverse slider 09. By combining the longitudinal slider 08 and the transverse slider 09, the cutting structure can be adjusted to different positions to achieve the effect of cutting paper of different sizes.

[0044] Specifically, the rotating structure includes a second motor 10 connected to the longitudinal slider 08, the housing of the second motor 10 being connected to the longitudinal slider 08, and the drive rod of the second motor 10 being connected to the cutting structure.

[0045] After the paper is cut longitudinally, if it needs to be cut laterally, simply start the second motor 10. The second motor 10 drives the cutting structure to rotate 90° to change the cutting blade 19 from longitudinal to lateral. If the position of the cutting blade 19 needs to be adjusted, the lateral drive structure can be started for adjustment.

[0046] Specifically, the cutting structure includes a fourth electric telescopic rod 11 connected to the drive rod of the second motor 10, a connecting rod 15 connected to the fourth electric telescopic rod 11, and a cutting blade 19 mounted on the connecting rod 15.

[0047] After adjusting the position of the cutting blade 19 to the cutting point of the paper, the fourth electric telescopic rod 11 is activated, which will cause the cutting blade 19 to move down and cut the printed paper.

[0048] When using this cutting structure, first adjust the cutting blade 19 to be directly above the appropriate cutting groove. Then, the operator places the printed paper to be cut on the paper placement plate 14. Next, activate the two first electric telescopic rods 02 on the support frame 01. The extension of the first electric telescopic rods 02 causes the push block 03 connected to the first electric telescopic rod 02 to move forward until it contacts the printed paper. Then, activate the second electric telescopic rod 05. The extension of the second electric telescopic rod 05 causes the first pressing plate 04 connected to the second electric telescopic rod 05 to press the printed paper firmly. Then, activate the fourth electric telescopic rod 11. The extension of the fourth electric telescopic rod 11 causes the cutting blade 19 to move downward, thus cutting the printed paper. After cutting the first position, if other positions need to be cut, the position of the cutting blade 19 can be adjusted through the horizontal sliding structure and the vertical sliding structure, as well as in conjunction with the rotation function of the second motor 10. After the cutting is completed, the first electric telescopic rod 02, the second electric telescopic rod 05, and the fourth electric telescopic rod 11 all retract. At this time, the staff only needs to remove the cut printing paper from the paper placement plate 14.

[0049] The cutting structure in this embodiment can be moved by connecting the cutting structure to the sliding structure. Multiple longitudinal cutting grooves 13 and transverse cutting grooves 22 are spaced apart on the paper placement plate 14, allowing for cutting at different positions of the paper without repeated adjustments. Only the position of the cutting blade 19 needs to be adjusted according to the required paper size. This cutting device can cut paper of various sizes, has a wider range of applications, is simple to operate, and has high cutting efficiency. Meanwhile, the fixing structure aligns the two ends of the printing paper on the paper placement plate 14 as the L-shaped pusher 03 moves forward vertically, resulting in more uniform cuts and improved product quality. Furthermore, after the L-shaped pusher 03 contacts the printing paper, the second electric telescopic rod 05 extends, causing the first pressing plate 04 to press the edges of the printing paper firmly, making the printing paper more stable during the cutting process.

[0050] Example 2

[0051] Based on Example 1, such as Figure 1 and Figure 2As shown, this embodiment provides a paper cutting structure. Unlike Embodiment 1, this embodiment has a crossbar 16 perpendicular to the connecting rod 15 connected to the connecting rod 15. Crossbars 16 are connected to the connecting rods 15 on both sides of the cutting blade 19. A second pressing structure is connected to the crossbar 16. The second pressing structure includes a fifth electrically operated telescopic rod 17 connected to the crossbar 16, and a second pressing plate 18 is connected to the telescopic end of the fifth electrically operated telescopic rod 17. Other structural features are the same as in Embodiment 1.

[0052] Compared with Embodiment 1, the advantage of the cutting structure in this embodiment is that by installing a second clamping structure on both sides of the cutting blade 19, the printing paper to be cut can be clamped by the second clamping structure during cutting, making the cutting blade 19 more stable when cutting the printing paper, reducing the burrs generated during the cutting process, further improving the quality of the paper after cutting, and reducing the generation of waste.

[0053] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
