Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or components / elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] Figure 1 This is a schematic left view of a height-limiting die-cutting mechanism provided in one embodiment of this utility model; Figure 2 This is a front view of a height-limiting die-cutting mechanism provided in one embodiment of this utility model; (e.g.) Figure 1-2 As shown, the height-limiting die-cutting mechanism includes: a frame 1, a die-cutting roller 2 mounted on the lower middle part of the frame 1, a steel roller 4 mounted on the frame 1 and above the die-cutting roller 2, and a rubber roller 7 mounted on the frame 1 and above the steel roller 4; wherein, the two ends of the die-cutting roller 2, the steel roller 4, and the rubber roller 7 are inserted with shaft brackets 3, and the shaft brackets 3 are fixedly connected to the frame 1; a spring 6 is provided between the shaft brackets 3 inserted into the steel roller 4 and the rubber roller 7; a gear disk is provided on the same side of the die-cutting roller 2, the steel roller 4, and the rubber roller 7, and the gear disks of the die-cutting roller 2, the steel roller 4, and the rubber roller 7 are connected in sequence; a motor is axially connected to the die-cutting roller 2.

[0021] Specifically, because traditional die-cutting mechanisms lack springs, the rubber roller 7 cannot press to the specified height. The applicant believes this is because the rubber roller itself has weight, and this weight pressing on the product can easily cause the product to be too thin. In the solution provided in this application, springs 6 are provided at both ends of the steel roller 4 and the rubber roller 7. The elastic force of the springs 6 can offset part of the weight of the rubber roller 7, making the product pressing process easier to control, thereby ensuring the stability of the height pressed down by the rubber roller.

[0022] According to the height-limiting die-cutting mechanism of this utility model, by setting springs at both ends of the shaft to provide support force, the product pressing process is easier to control, thereby ensuring the stability of the height pressed down by the rubber roller.

[0023] According to one embodiment of the present invention, a snap-fit ​​block 5 is provided between the spring 6 and the shaft frame 3 into which the steel roller 4 is inserted, and the lower end of the spring 6 is snapped into the snap-fit ​​block 5.

[0024] Specifically, in order to make the connection of spring 6 more stable and to prevent spring 6 from falling off due to vibration caused by the operation of the die-cutting mechanism or accidental contact by the operator, a snap-fit ​​block 5 can be added to snap the spring in the snap-fit ​​block 5, thereby ensuring the spring is stable.

[0025] According to one embodiment of the present invention, a snap-fit ​​hole is provided in the middle of the upper end of the snap-fit ​​block 5, and the spring 6 is snapped in through the snap-fit ​​hole.

[0026] Specifically, in one embodiment provided by the applicant, the spring 6 is secured in the snap-fit ​​hole provided on the snap-fit ​​block 5, thereby ensuring the spring is stable.
