Description

Technical Field

[0001] This utility model relates to the technical field of die-cutting machine accessories, and in particular to a modular die-cutting machine cutting device and a die-cutting machine. Background Technology

[0002] In the packaging box processing, a die-cutting machine is needed to cut cardboard into shapes that conform to the unfolded state of the box. The die-cutting machine uses steel blades, metal molds, and steel wire (or a template engraved from a steel plate) to apply a certain pressure through an imprinting plate to cut the printed material or cardboard into a specific shape. Die-cutting machines are classified into flatbed die-cutting machines, rotary die-cutting machines, and rotary-flatbed die-cutting machines according to different die-cutting methods.

[0003] Most existing rotary die-cutting machines have a die-cutting roller and a pressure roller. A template is set on the die-cutting roller, and a creasing knife is set on the template. The die-cutting roller and the pressure roller work together to cut the cardboard using the creasing knife on the template. However, most existing templates are a single piece of curved board. Although using a one-piece board makes it easier to install the creasing knife, the cost is too high. Moreover, over time or after a long period of disuse, the curved board is prone to deformation, which affects the yield of cardboard cutting.

[0004] In view of this, the inventors have specifically designed a modular die-cutting machine cutting device and a die-cutting machine, which leads to this invention. Utility Model Content

The template 40 is arc-shaped and includes several splicing plates 41 arranged in a circular array to form the arc-shaped template 40. The creasing knife is configured according to actual needs and will not be described in detail. Specifically, the splicing plates 41 are fixed with glue or other existing means. After the splicing plates 41 are assembled, the creasing knife is then fixedly installed according to actual needs. The cutting device of this utility model modularizes the template 40, that is, the template 40 is spliced ​​together by several splicing plates 41. The splicing plates 41 are fixed into an arc-shaped template 40. The splicing plates 41 have smaller deformation and are not easily deformed relative to the overall template 40.

[0034] Please refer to details.

[0037] In summary, the cutting device of this utility model modularizes the template 40, that is, the template 40 is spliced ​​together by several splicing plates 41. The splicing plates 41 are fixed into an arc-shaped template 40. The splicing plates 41 have smaller deformation and are not easily deformed relative to the overall template 40, which improves the service life of the cutting device. Example

[0038] Please see Figures 1 to 5 This is a die-cutting machine according to Embodiment 2 of the present invention, which adopts a modular die-cutting machine cutting device from Embodiment 1. The die-cutting machine also includes a guiding device for guiding the cardboard; the guiding device includes a third rotating shaft 50 and a fourth rotating shaft 60 arranged side by side along the vertical direction, a first guide roller 51 and a second guide roller 61 respectively sleeved on the outside of the third rotating shaft 50 and the fourth rotating shaft 60, and two limiting mechanisms 70 arranged side by side on the first guide roller 51. The limiting mechanisms 70 are used to position the cardboard during the conveying process so that the cardboard can be better conveyed to the corresponding cutting die 40. The outer surface of the limiting mechanism 70 is as close as possible to the outer surface of the second guide roller 61.

[0039] Please refer to details. Figure 3 , 4The limiting mechanism 70 is adjustablely mounted on the first guide roller 51. The limiting mechanism 70 includes two cooperating first bushings 71 and second bushings 72, which are fitted onto the outer surface of the first guide roller 51. Both the first bushing 71 and the second bushing 72 are semi-circular. The first bushing 71 has a first protrusion 711 and a second protrusion 712 on the side of the first bushing 71 closest to the second bushing 72. The second bushing 72 has a first groove 721 corresponding to the first protrusion 711 and a second groove 722 corresponding to the second protrusion 712. The first protrusion 711 is embedded in the first groove 721 and rotates through a pin 73. The second protrusion 712 is embedded in the second groove 722 and is fixed or limited by bolts. The limiting mechanism 70 of this utility model is set to be adjustable, which is convenient to adapt to the die cutting of cardboard of different widths. Specifically, the position of the limiting mechanism 70 can be adjusted according to the width of the cardboard to be die-cut and the position of the template 40. Preferably, a scale line can be set on the outer surface of the first guide roller 51 to facilitate quick adjustment according to the width of the cardboard.
