[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0034] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model. Example

[0035] See Figures 1-4 As shown, a scriber module for a die-cutting machine includes a first bearing housing 1 and a second bearing housing 2. The first bearing housing 1 and the second bearing housing 2 serve as the supporting foundation for the entire module, securely mounted in corresponding positions on the die-cutting machine, providing reliable support and positioning for the drive shaft 3. The first bearing housing 1 and the second bearing housing 2 contain bearings connected to the drive shaft 3, with one end of the drive shaft 3 exposed outside the first bearing housing 1. A drive component 4 is disposed on the outside of the first bearing housing 1, connected to one end of the drive shaft 3, transmitting power to the drive shaft 3 so that it can rotate stably along its own axis.

[0036] Several tool holders 5 are mounted on the drive shaft 3, and each tool holder 5 is equipped with a cutting blade 6. The drive shaft 3, located between the first bearing housing 1 and the second bearing housing 2, has a regular polygonal cross-section. Correspondingly, the mounting holes 55 of the tool holders 5 are also designed as regular polygons and perfectly fit the drive shaft 3. This design cleverly achieves relative fixation between the tool holders 5 and the drive shaft 3 in the circumferential direction, avoiding circumferential rotation between them and ensuring the stability and accuracy of the cutting blade 6 during operation.

[0037] The first locking holes 51 on the tool holder 5 are respectively opposite one side of the drive shaft 3. The locking components, such as bolts, installed in the first locking holes 51 securely fix the tool holder 5 to the drive shaft 3 by tightly abutting against the side of the drive shaft 3. The above locking method is not only simple in structure and convenient in operation, but also ensures the stability of the tool holder 5 on the drive shaft 3, and improves the convenience and stability of the scribing module assembly.

[0038] Furthermore, the first locking hole 51 is perpendicularly distributed to the corresponding side of the drive shaft 3. This perpendicular distribution ensures that the force applied by the locking component is uniform and acts directly on the side of the drive shaft 3, enhancing the locking effect, making the connection between the tool holder 5 and the drive shaft 3 more stable, preventing loosening, and ensuring the stable operation of the scribing module.

[0039] In the die-cutting machine scribing module of this utility model, the drive shaft 3 has clearly defined functional zones to achieve efficient cooperation between various components. Combined with... Figure 2 As shown, the drive shaft 3 is provided with an installation area 31 for placing the tool holder 5, a connection area 32 passing through the first bearing seat 1 and the second bearing seat 2, and a transmission area 33 connected to the drive component 4.

[0040] The drive shaft 3, located in the connecting area 32 and the transmission area 33, has a circular cross-section. The circular structure offers advantages such as ease of machining and good compatibility with bearing housings and drive components. The circular structure of the connecting area 32 ensures smooth rotation of the drive shaft 3 within the first bearing housing 1 and the second bearing housing 2, reducing friction and wear; the circular structure of the transmission area 33 facilitates a stable connection with the drive component 4, enabling efficient power transmission.

[0041] The drive shaft 3, located in the mounting area 31, has a regular polygonal cross-section. This structure allows the mounting hole of the tool holder 5 to fit perfectly, effectively preventing the tool holder 5 from rotating circumferentially on the drive shaft 3 and ensuring the stability of the cutting tool 6 during operation.

[0042] Preferably, the aforementioned regular polygonal structure is a regular pentagonal structure. The regular pentagonal structure ensures that the tool holder 5 and the drive shaft 3 are circumferentially fixed, while having relatively low machining difficulty and providing good structural stability. It balances economy and practicality while meeting the functional requirements of the module, thus helping to improve the overall performance and reliability of the scribing module.

[0043] In this embodiment, the driving component 4 includes a fixed frame 41 fixed on the first bearing seat 1. The fixed frame 41 provides installation space and stable support for the internal transmission components. A worm gear 42 and a worm 43 are disposed within the fixed frame 41. The worm gear 42 is tightly connected to one end of the drive shaft 3 to achieve power transmission. One end of the worm 43 is connected to a handwheel 44, which can drive the worm 43 to rotate by rotating the handwheel 44. The worm gear 42 and the worm 43 are driven by meshing, which has self-locking properties and prevents the drive shaft 3 from rotating in the opposite direction due to external forces. Furthermore, a bearing connected to the worm 43 is provided on the fixed frame 41. This bearing effectively reduces the frictional force when the worm 43 rotates, ensuring the smoothness and efficiency of the transmission process.

[0044] Combination Figure 4 As shown, in this embodiment, the blade holder 5 is provided with a blade groove 54. The lower end, left side and right side of the blade groove 54 are open structures. This design makes it easy for the blade 6 to be installed and adjusted from multiple directions.

[0045] The tool holder 5 is also provided with a second locking hole 52 and a third locking hole 53, wherein the third locking hole 53 penetrates the tool groove 54. The upper end of the blade 6 can be embedded into the tool groove 54, and the upper end of the blade 6 is provided with a fourth locking hole corresponding to the third locking hole. In actual installation, the bolt assembly is inserted into the third locking hole 53 and the fourth locking hole in sequence, and the blade 6 is firmly fixed to the tool holder 5 by tightening the bolt assembly. This connection method is simple and reliable.

[0046] The second locking hole 52 communicates with the blade groove 54, and a limiting member is provided inside it to abut against the blade 6. This limiting member can be a screw or the like. By adjusting the position of the limiting member in the second locking hole 52, the blade 6 can be further positioned and limited to prevent the blade 6 from shaking in the blade groove 54.

[0047] In addition, a stop 7 is provided on the blade of the blade 6, and the stop 7 is located above the cutting edge of the blade 6. The stop 7 can play a certain role in protection and positioning, preventing the cutting edge from penetrating too deeply into the material during the operation of the blade 6, and also helps to control the depth and precision of die cutting, thereby improving the die cutting quality.

[0048] The die-cutting machine scriber module provided by this utility model changes the cross-section of the drive shaft 3 in contact with the cutter holder 5. The cross-section of the drive shaft 3 in the mounting area 31 is set as a regular polygon, and the mounting hole 55 of the cutter holder 5 is adapted to it. This structure effectively avoids circumferential rotation between the two, ensuring that the drive shaft 3 can stably drive the cutter holder 5 and the blade 6 when rotating. Simultaneously, the cutter holder 5 can be easily axially adjusted on the drive shaft 3. After adjustment, the locking element in the first locking hole 51 securely fixes the cutter holder 5 to the drive shaft 3, achieving a stable connection between the two.

[0049] In addition, the blade 6 can be easily embedded in the blade groove 54 of the blade holder 5. By adjusting its position in the blade groove 54, and then using the bolt assembly in the third locking hole 53 and the fourth locking hole to lock it, different die-cutting requirements can be met, which greatly improves the convenience and stability of the scribing module assembly.
