[0024] exist Figure 1-3 In the figure, the adjustment assembly 3 is composed of eleven components, namely, a mounting seat 301, a connecting block 302, a guide rod 303, a support block 304, a screw rod 305, a reduction motor 306, a connecting head 307, a hydraulic cylinder 308, a fixing plate 309, a threaded barrel 310 and a bolt 311, so as to achieve the advantages of easy adjustment, reduced cost and convenient cutting.

[0025] exist Figure 1 and Figure 2 In the figure, a mounting seat 301 is arranged inside the support frame 2 to provide an installation space and position for the installation and arrangement of some components and to play the role of connecting various components.

[0026] exist Figure 2 In the figure, connecting blocks 302 are installed on the left and right sides of the mounting seat 301, and two guide rods 303 are installed between the front and rear inner walls of the support frame 2. The connecting blocks 302 slide through the inner sliding holes and the guide rods 303 to constrain the moving direction of the mounting seat 301, so that the mounting seat 301 can only move horizontally forward and backward.

[0027] exist Figure 1 and Figure 2 In the figure, a support block 304 is installed on the top of the support frame 2, and the front side of the support block 304 is rotatably connected to a screw rod 305, and the front end of the screw rod 305 is connected to a reduction motor 306. The reduction motor 306, the screw rod 305 and the support block 304 constitute a threaded conveying structure.

[0028] exist Figure 2 In the embodiment, the outer surface of the screw rod 305 is connected with a connector 307 which is threadedly connected to the screw rod 305 via a screw hole, so that the mounting seat 301 connected at the bottom is affected by the rotation of the screw rod 305 and is driven by the rotation of the screw rod 305 .

[0029] exist Figure 2 and Figure 3 In the embodiment, two hydraulic cylinders 308 are installed inside the mounting seat 301 to push the cutting tool 4 to move up and down for cutting, which greatly reduces the cost required for adjusting the cutting height and reduces the cost of use.

[0030] exist Figure 2 and Figure 3 In the figure, the bottom of the two hydraulic cylinder 308 pistons are installed with fixed plates 309, the bottom of the two fixed plates 309 are rotatably connected with threaded tubes 310, the inside of the two threaded tubes 310 are connected with bolts 311, which are used to connect the hydraulic cylinder 308 pistons and the cutting tool 4 from top to bottom.

[0031] It should be noted that this section is intended to provide a background or context for the implementation methods stated in the claims, and detailed descriptions of known functions and known components are omitted. At the same time, fixed and movable installations are determined according to actual application methods. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art because it is included in this section.

[0032] When implementing, follow these steps:

[0033] 1) First, start the output shaft of the reduction motor 306 to rotate, drive the screw rod 305 to rotate, and use the threaded connection transmission connector 307 to make the connector 307 drive the mounting seat 301;

[0034] 2) Then, since the mounting seat 301 is slidably connected to the guide rod 303 through the connecting block 302, the connecting head 307 drives the mounting seat 301 to move only forward and backward;

[0035] 3) Finally, when the device moves to a suitable distance, the piston of the hydraulic cylinder 308 is started to extend, pushing the fixing plate 309, the threaded cylinder 310, and the bolt 311 to drive the cutting tool 4 to move downward for cutting.

[0036] To sum up, the printing cutting machine that is easy to adjust the cutting distance is designed to separate the cutting tool and the processing area by setting the cutting tool 4 above the workbench 1, thereby avoiding the occurrence of unclear adjustment caused by the cutting tool and the processing area moving together, and ensuring the accuracy of the adjustment. At the same time, the design of using two hydraulic cylinders 308 pistons to telescopically drive the cutting tool 4 to move up and down can achieve the effect of adjusting the cutting height, which greatly reduces the cost required for height adjustment. The cutting tool 4 and the hydraulic cylinder 308 are fixed by a threaded connection between a rotatable threaded barrel 310 and a fixed bolt 311, and can then be separated by rotating the threaded barrel 310, which greatly reduces the convenience of disassembly and maintenance for the staff and facilitates the operation and use of the staff.

[0037] Moreover, the design of the reduction motor 306, the screw rod 305 and the support block 304 is used to form a one-way thread transmission structure, and the mounting base 301 that is limited by the sliding of the connecting block 302 and the guide rod 303 is used as a receiving structure. After the screw rod 305 rotates, the connecting head 307 can be directly transmitted to drive the mounting base 301 to move forward and backward, thereby pulling the cutting tool 4 to move synchronously, reducing the components required for forward and backward adjustment, separating the movement of the cutting part from the processing area, increasing the convenience of adjusting the cutting position, achieving the effect of precise adjustment, further facilitating the operation and use of the staff, and solving the problem that the cutting area in the comparison document moves together, which is not conducive to the corresponding cutting according to the size of the printed matter, and reduces the convenience of adjustment.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
