[0022] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 5 , the present utility model provides embodiments of the following two preferred solutions:

[0024] Embodiment 1: A circular knife die with a limit protection structure includes a limit plate 7. Inside the limit plate 7, there is a main spindle body 1. The main spindle body 1 serves as the core support structure of the entire circular knife die, carrying the circular knife die 2 and other accessories to ensure its stable operation. On the circumferential surface of the main spindle body 1, the circular knife die 2 is fixedly connected. The circular knife die 2 is a component directly involved in cutting or processing work and is fixed on the main spindle body 1 and rotates with the main spindle body 1. The limit plate 7 restricts the position of the circular knife die 2 on the main spindle body 1, preventing it from shifting or shaking during use, and improving the working accuracy and safety. The number of limit plates 7 is set to four, and two of them are symmetrically arranged in a group at the upper and lower ends of the circular knife die 2. The two limit plates 7 on the same side are correspondingly arranged. On the circumferential surface of the main spindle body 1, there is an installation groove 3. The installation groove 3 is used to install and fix the limit plate 7 to ensure that it can be firmly combined with the main spindle body 1. On the circumferential surface of the installation groove 3, a positioning block 4 is fixedly connected. The positioning block 4 is used in cooperation with the positioning groove 710 in the limit plate 7 to achieve the precise installation and positioning of the limit plate 7 and prevent it from loosening during use. The number of positioning blocks 4 is set to two and is symmetrically arranged on the circumferential surface of the installation groove 3. On the circumferential surface of the main spindle body 1, a chuck 5 is fixedly connected. The chuck 5 supports or guides the movement of the circular knife die 2, reduces friction and wear, and improves the running smoothness. The number of installation grooves 3 and chucks 5 is both set to two and is symmetrically arranged at the upper and lower ends of the circular knife die 2. The chuck 5 is located outside the installation groove 3. At the top of the main spindle body 1, a driving gear 6 is fixedly connected. The driving gear 6 connects the main spindle body 1 with an external power source and rotates to drive the main spindle body 1 and the circular knife die 2 to work.

[0025] Embodiment 2: On the basis of Embodiment 1, the limiting plate 7 includes a plate body 701, a clamping block 702, a limiting groove 703, a disassembly groove 704, a clamping groove 705, a spring groove 706, a limiting spring 707, a limiting rod 708, a movable groove 709 and a positioning groove 710. The plate body 701 is semi-circular arc-shaped. One end of the plate body 701 is fixedly connected with a clamping block 702. The inside of the clamping block 702 is provided with a limiting groove 703. The inside of the clamping block 702 is provided with a disassembly groove 704, and the disassembly groove 704 extends into the limiting groove 703. The inside of the end of the plate body 701 away from the clamping block 702 is provided with a clamping groove 705. The clamping block 702 is correspondingly arranged with the clamping groove 705 and is clamped with each other. The bottom of the clamping groove 705 is provided with a spring groove 706. The bottom end of a limiting spring 707 is fixedly connected inside the spring groove 706. The top end of the limiting spring 707 is fixedly connected with a limiting rod 708. The diameters of both ends of the limiting groove 703 and the limiting rod 708 are equal, and the limiting groove 703 is sleeved with the limiting rod 708. The diameters of the middle part of the disassembly groove 704 and the limiting rod 708 are equal, and the disassembly groove 704 is slidably connected with the limiting rod 708. The bottom end of the limiting rod 708 is slidably connected with the spring groove 706. The limiting groove 703, the disassembly groove 704, the limiting rod 708 and the limiting spring 707 allow the limiting plate 7 to be easily disassembled when needed, while ensuring its stability during work. The limiting spring 707 provides elastic force so that the limiting rod 708 can automatically snap into the limiting groove 703. The disassembly groove 704 is convenient for pressing the limiting rod 708 by an external force for disassembly. The top end of the clamping groove 705 is provided with a movable groove 709. The movable groove 709 provides additional moving space for the limiting rod 708 to ensure its smoothness during disassembly and installation. The top end of the limiting rod 708 is slidably connected with the movable groove 709. The inner side wall of the plate body 701 is provided with a positioning groove 710. The positioning groove 710 is correspondingly arranged with the positioning block 4 and is clamped with each other.

[0026] During actual use, through the rotation of the main spindle body 1, the circular cutter die 2 is driven to perform cutting or processing work. The limiting plate 7 is firmly fixed on the main spindle body 1 through the clamping structure of the clamping block 702 and the clamping groove 705 inside it, and the sleeved relationship between the limiting rod 708 and the limiting groove 703, preventing the offset of the circular cutter die 2 and restricting the cutting depth of the circular cutter die 2. At the same time, the cooperation between the positioning block 4 and the positioning groove 710 further enhances the positioning accuracy of the limiting plate 7. When it is necessary to replace or maintain the circular cutter die 2, the limiting plate 7 can be easily disassembled by pressing the limiting rod 708 through the disassembly groove 704.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
