[0024] The hollow die cutting device of the utility model will be described in more detail below in conjunction with the schematic diagram, wherein the preferred embodiment of the utility model is shown, and it should be understood that the utility model described herein can be modified by a person skilled in the art, while still achieving the advantageous effects of the utility model. Therefore, the following description should be understood as being widely known to a person skilled in the art, and not as a limitation to the utility model.

[0025] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0026] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a hollow die-cutting device, including an operating table 1, a die-cutting roller 2, a transmission sleeve 3 and a driving assembly.

[0027] Specifically, the die-cutting roller 2 is detachably arranged on the operating table 1 , and a hollow mold 4 is arranged on the roller surface of the die-cutting roller 2 .

[0028] The transmission sleeve 3 is detachably arranged on the die-cutting roller 2 , and the transmission sleeve 3 rotates synchronously with the die-cutting roller 2 . The transmission sleeve 3 is used to transmit and convey the hollow parts located on the operating table 1 .

[0029] The driving assembly is installed on the operating table 1, and is transmission-connected with the die-cutting roller 2, and hollows out and cuts the hollowed-out piece by driving the die-cutting roller 2 to rotate.

[0030] In this embodiment, after the die-cutting roller 2 is installed on the operating table 1, the die-cutting roller 2 and the transmission sleeve 3 rotate synchronously under the drive of the driving component. In the process of the transmission sleeve 3 rotating, the transmission sleeve 3 can drive the die-cutting piece to move along the surface of the operating table 1. At the same time, the hollowing mold 4 on the die-cutting roller 2 can perform hollowing die-cutting operations on the die-cutting piece. Since the die-cutting roller 2 and the transmission sleeve 3 move synchronously, the hollowing deformation of the hollowing piece caused by the asynchronous conveying and hollowing can be effectively avoided, and the hollowing die-cutting quality of the product is greatly improved.

[0031] Furthermore, two mounting brackets 5 are arranged in parallel and vertically on the operating table 1 , a semicircular mounting groove 6 is arranged at the end of the mounting bracket 5 , and the die-cutting roller 2 is rotatably arranged in the mounting groove 6 via a connecting bearing 12 .

[0032] Specifically, the connecting bearing 12 is sleeved on the die-cutting roller 2, and the connecting bearing 12 is mounted in the mounting groove 6. After the connecting bearing 12 is mounted in the mounting groove 6, the connecting bearing 12 is slidably connected to the inner wall of the mounting groove 6, and the die-cutting roller 2 can be directly mounted in the mounting groove 6 through the connecting bearing 12, thereby realizing the detachable connection of the die-cutting roller 2 and facilitating the replacement of the die-cutting roller 2.

[0033] In order to ensure that the die-cutting roller 2 can be stably located in the mounting groove 6, a fastening sleeve 13 is provided above the mounting groove 6, and the fastening sleeve 13 is sleeved on the outside of the connecting bearing 12, one end of the fastening sleeve 13 is rotatably connected to the mounting bracket 5, and the other end of the fastening sleeve 13 is detachably connected to the mounting bracket 5 via a fastening knob 14.

[0034] Furthermore, a plurality of positioning grooves 7 are provided on the roller surface of the die-cutting roller 2 , and the transmission sleeve 3 is clamped in the positioning grooves 7 .

[0035] Specifically, an elastic wrapping layer 8 is provided on the side circumferential surface of the transmission sleeve 3 , and the elastic wrapping layer 8 is in contact with the upper surface of the operating table 1 and in sliding contact.

[0036] During the rotation of the die-cutting roller 2, the transmission sleeve 3 rotates with the die-cutting roller 2, and the hollowed-out pieces on the operating table 1 can be transmitted and conveyed during the rotation of the transmission sleeve 3. At the same time, the hollowing mold 4 on the roller surface of the die-cutting roller 2 performs hollowing and cutting operations on the hollowed-out pieces.

[0037] Furthermore, the driving assembly includes a driving motor 9 , a driving gear 10 and a transmission gear 11 .

[0038] Specifically, the driving motor 9 is installed on the operating table 1, and the driving motor 9 is used to provide a power source.

[0039] The driving gear 10 is fixedly mounted on the output shaft of the driving motor 9 .

[0040] The transmission gear 11 is fixedly mounted on the die-cutting roller 2 , and the transmission gear 11 is meshedly connected with the driving gear 10 .

[0041] In this embodiment, driven by the driving motor 9, the die-cutting roller 2 starts to rotate through the transmission of the driving gear 10 and the transmission gear 11, and can perform hollow die-cutting operations on the die-cutting pieces while conveying the die-cut pieces.

[0042] It should be noted that when the die-cutting roller 2 is mounted on the mounting groove 6, the transmission gear 11 on the die-cutting roller 2 is meshed with the driving gear 10, which not only realizes the detachable installation of the die-cutting roller 2, but also realizes the transmission connection between the die-cutting roller 2 and the driving assembly.

[0043] In a specific embodiment, the drive motor 9 is a stepper motor. A stepper motor is a motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. Each time a pulse signal is input, the rotor rotates an angle or moves forward one step. The angular displacement or linear displacement output is proportional to the number of pulses input, and the rotation speed is proportional to the pulse frequency. The drive motor 9 is a stepper motor, which can accurately control the hollow die cutting rate.
