[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The utility model provides Figure 1-5 The printing die-cutting machine shown in the figure is used for printing production, including a machine body 1, a base of the machine body 1 is provided with a placement slot 2, a cylinder 3 is embedded and installed inside the top plate of the machine body 1, and a cutter head 4 is fixedly connected to the telescopic end of the cylinder 3, and further includes:

[0028] The protective assembly 5 has a protective cover 1 501 movably mounted inside the machine body 1. The protective cover 1 501 is movably mounted on the outside of the cutter head 4. The protective cover 1 501 is movably mounted on the outside of the protective cover 2 502. The bottom of the protective cover 2 502 is fixedly connected to a positioning block 7.

[0029] The mounting assembly 6 is provided with a mounting notch 601 on the top of the protective cover 501 , and a snap-fit ​​block 603 is rotatably connected to the interior of the mounting notch 601 through a mounting rod 602 , and the snap-fit ​​block 603 is snap-fitted to the snap-fit ​​groove 604 .

[0030] The top and bottom of the protective cover 1 501 and the protective cover 2 502 are both through-shaped, which facilitates the movement of the cutter head 4 for die-cutting operations.

[0031] The bottom of the two side walls of protective cover 1 501 are fixedly connected to the limiting blocks 504, and the limiting blocks 504 move inside the limiting grooves 505 preset inside protective cover 2 502, and the limiting blocks 504 and the limiting grooves 505 are movably connected through springs 506 to ensure the stability of the movement of protective cover 1 501 and protective cover 2 502.

[0032] The upper and lower ends of the spring 506 are fixedly connected to the limit block 504 and the inner wall of the limit groove 505 respectively. The force applied by the spring 506 enables the positioning block fixedly connected to the lower end of the protective cover 2 502 to completely support the paper to be processed placed inside the placement groove 2, which serves as a clear indication of the cutting area and ensures the accuracy of subsequent die-cutting processing.

[0033] An installation groove 503 is provided inside the protective cover 2 502, and the installation groove 503 is connected to the limit groove 505. The bottom of the installation groove 503 is closed, and the top of the installation groove 503 is open. The inner wall of the installation groove 503 is in contact with the outer wall of the protective cover 1 501 and realizes a sliding connection to ensure the stability of the activities of the protective cover 1 501 and the protective cover 2 502.

[0034] The outer ring of the mounting rod 602 is movably sleeved with a torsion spring, and the two ends of the torsion spring are respectively fixedly connected to the locking block 603 and the inner wall of the mounting notch 601, which facilitates the subsequent disassembly and assembly of the entire protective assembly 5, so as to facilitate the maintenance of the cutter head 4. The force applied by the torsion spring acts on the locking block 603 to match the locking block 603 with the locking groove 604, ensuring the stability of the installation of the entire protective assembly 5, so that the two sets of movably connected protective covers can better protect the cutter head 4.

[0035] Working principle: When using a printing die-cutting machine for printing production, first, by shifting the protective cover 502, the protective cover 502 moves upward on the outer ring of the protective cover 1 501, and the paper to be processed is placed into the placement slot 2. Subsequently, the protective cover 502 is shifted so that the lower end of the protective cover 502 abuts against the paper to be processed placed in the placement slot 2. The cylinder 3 is started to drive the cutter head 4 fixedly connected to the telescopic end of the cylinder 3 to descend. The cutter head 4 descends to cut the paper to be processed placed in the placement slot 2, and the cutter head 4 moves inside the entire protective space formed by the protective cover 1 501 and the protective cover 2 502. In this way, the cutter head 4 does not leak out, thereby reducing the occurrence of dangerous accidents.

[0036] Subsequently, the two sets of locking blocks 603 are moved toward each other, so that the "7"-shaped locking block 603 rotates away from the inside of the matching locking groove 604, which makes it convenient to disassemble and replace the entire protective assembly 5, and to perform maintenance operations on the cutter head 4 inside the space protection space composed of protective cover 1 501 and protective cover 2 502. The force applied by the subsequent torsion spring acts on the locking block 603 to match the locking block 603 with the locking groove 604, ensuring the stability of the installation of the entire protective assembly 5, so that the two sets of movably connected protective covers can better protect the cutter head 4.

[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
