Description

Technical Field

[0001] The utility model relates to a die-cutting machine, in particular to a plate distance adjusting device of the die-cutting machine. Background Art

[0002] Digital die-cutting machines use computer programming to control cutting tools to achieve precise cutting of various materials. The control system controls the forward and backward movement of the material. During the forward and backward movement of the material, the die-cutting knife group moves horizontally according to the corresponding graphics to die-cut the material. Compared with traditional die-cutting machines, digital die-cutting machines do not need to use customized physical molds to form specific cutting shapes, but use digital control technology to cut directly on the material.

[0003] The digital die-cutting machine in the prior art is usually a set of die-cutting knife groups, and the die-cutting efficiency is low. In order to improve the die-cutting efficiency, multiple sets of die-cutting knife groups are usually set. For materials of different specifications, the center distances of adjacent patterns are different, and the distances between the die-cutting knife groups are relatively fixed. If the distances between the die-cutting knife groups are adjusted, other parts of the die-cutting machine need to be adjusted accordingly. Therefore, in the prior art, multiple sets of die-cutting knife groups are usually used by one die-cutting machine for materials of one specification, which is costly and occupies a large area. Summary of the invention

[0004] The utility model aims at the shortcomings of the prior art and provides a plate spacing adjusting device which can improve the die cutting efficiency and is suitable for die cutting machines of different specifications.

[0005] To solve the above technical problems, the utility model solves the problems through the following technical solutions: a plate spacing adjustment device of a die-cutting machine comprises a die-cutting mechanism and a material guiding mechanism, the die-cutting mechanism comprises a die-cutting knife group, the die-cutting knife group has two groups, and the die-cutting knife group has a transmission mechanism for making it move laterally; the plate spacing adjustment material guiding mechanism comprises a fixed material guiding roller and a movable spacing adjusting roller, the movable spacing adjusting roller is arranged below the die-cutting knife group, the fixed material guiding roller is arranged between the movable material guiding roller and the die-cutting knife group, and the movable spacing adjusting roller is transmission-connected with a driving mechanism for driving it to rise and fall; when adjusting the machine, the movable spacing adjusting roller can adjust the material length between the two groups of die-cutting knife groups; when working, the position of the movable spacing adjusting roller is relatively fixed.

[0006] Preferably, the two sets of die-cutting knife groups are respectively arranged on the mounting base facing back to back.

[0007] There are two transmission mechanisms, which are respectively arranged on both sides of the mounting seat, and each die-cutting knife group is respectively connected to the transmission mechanism.

[0008] Furthermore, the transmission mechanism has one, the mounting seat is slidably arranged on the base left and right, the transmission mechanism is arranged on the base, the transmission mechanism is arranged on the base, and the mounting seat is transmission-connected to the transmission mechanism.

[0009] Preferably, the driving mechanism includes a lifting seat and a lifting power source for driving the lifting seat to move up and down, the movable spacing roller is arranged on the lifting seat, and the lifting seat moves up and down to adjust the distance between the movable spacing roller and the fixed material guide roller.

[0010] There are at least two movable distance-adjusting rollers, which are respectively arranged on both sides of the lifting seat, and the number of the fixed material guiding rollers is consistent with the number of the movable distance-adjusting rollers.

[0011] Furthermore, the lifting power source is a servo motor.

[0012] Preferably, the die-cutting knife group includes a movable seat and a plurality of die-cutting knives, wherein the die-cutting knives are arranged on a slide block, and the slide block is arranged on the movable seat via a transverse track.

[0013] As a preferred embodiment, the utility model has significant technical effects due to the adoption of the above technical solution:

[0014] 1. Two sets of die-cutting knife groups improve efficiency. By driving the movable adjusting roller to move up and down, the distance between the movable spacing roller and the fixed guide roller is adjusted to adapt to materials of different specifications. When the center distance between adjacent patterns increases, the movable spacing roller descends to increase the length of the material between the two sets of die-cutting knife groups (the distance between the movable spacing roller and the fixed guide roller increases). When the center distance between adjacent patterns decreases, the movable spacing roller rises to increase the length of the material between the two sets of die-cutting knife groups (the distance between the movable spacing roller and the fixed guide roller decreases).

[0015] 2. One power source drives the transmission mechanism of two sets of die-cutting knife groups at the same time, reducing costs while improving work accuracy;

[0016] 3. The servo motor drives the movable pitch-adjusting roller to move up and down, further ensuring the die-cutting accuracy and improving the yield rate;

[0017] 4. According to the distance between patterns, the distance between adjacent die cutters can be adjusted by moving the slider to further adapt to materials of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS

After the debugging is completed, the machine is turned on, and the multiple die-cutting knife groups 1 cut the material. During the working process, the position of the movable distance-adjusting roller 4 remains unchanged.
