Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to an adjustable die-cutting device. Background Technique

[0002] The die-cutting device of a printing machine is also called a die-cutting machine and a numerical control punching machine. It is mainly used for die-cutting (full cutting, half cutting), indentation, hot stamping, laminating, and automatic waste discharging of some non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronics, mobile phone gaskets, etc. The die-cutting machine uses steel knives, hardware molds, steel wires (or templates engraved from steel plates), and applies a certain pressure through an impression plate to roll and cut printed products or cardboard into a certain shape. It is an important device for post-printing packaging processing and forming. The working principle of the die-cutting machine is to use steel knives, hardware molds, steel wires (or templates engraved from steel plates), and apply a certain pressure through an impression plate to roll and cut printed products or cardboard into a certain shape. If the entire printed product is pressed and cut into individual graphic products, it is called die-cutting. If steel wires are used to press marks or leave bending grooves on the printed product, it is called indentation. If a three-dimensional pattern or font is hot-stamped on the surface of the printed product by heating two yin-yang templates to a certain temperature, it is called hot stamping. If one substrate is laminated on another substrate, it is called laminating. Excluding the parts other than the genuine products is called waste discharging. The above can be collectively referred to as die-cutting technology.

[0003] After each die-cutting operation of the existing die-cutting device, some waste paper edges or paper fluff will adhere to the surface of the cutter head. In the short term, it has little impact on the cutter head. However, after using it for a period of time, the more impurities accumulate on the surface of the cutter head, the more it will affect the use state of the cutter head and even wear the cutter head. At the same time, for products of different thicknesses, the die-cutting device generally cannot adjust its own die-cutting depth, so it is impossible to effectively and efficiently perform die-cutting operations on products of different thicknesses. Therefore, an adjustable die-cutting device is proposed.

[0004] The existing patent (publication number: CN218195512U) discloses a die-cutting machine fixing device capable of adjusting the die-cutting depth, including an outer box body, the lower end of the outer box body is fixedly connected with a support seat, and the upper end of the outer box body is fixedly connected with a processing plate. This die-cutting machine fixing device capable of adjusting the die-cutting depth uses a fixing seat to limit both sides of the cardboard, separates each cardboard, which is convenient for die-cutting processing. At the same time, by rotating the adjusting handle, the threaded rod is driven to rotate, thereby pushing the limiting plate to move, realizing the limit fixation of the side of the cardboard, avoiding the offset of the cardboard during die-cutting processing, ensuring the accuracy of die-cutting processing. And by placing the die-cutting tool die into the installation groove, during die-cutting processing, the driving cylinder pushes the movable plate to move downward, and the pressing plate presses the die-cutting tool die, thereby performing die-cutting processing on the cardboard, which is convenient for the installation and replacement of the die-cutting tool die, and different die-cutting tool dies can be replaced to adjust the die-cutting thickness, improving the practicability. The inventor found the following problems in the prior art during the implementation of the present invention: 1. The waste paper edges and paper fluff generated on the surface of the tool head by the existing die-cutting device cannot be cleaned in time, resulting in rapid wear of the tool head and easy cause of equipment failures, affecting the die-cutting efficiency; 2. The existing die-cutting thickness is not easy to adjust, which is not convenient for die-cutting operations on products of different thicknesses. Summary of the Utility Model

[0030] The usage method and advantages of the present utility model: For this adjustable die-cutting device, during use, the working process is as follows:

[0031] As Figure 1 ,Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , first place the product to be processed on one side of the conveyor track 2, and adjust the height of the supporting platform 601 according to the thickness of the product to be die-cut. The specific operation method is to rotate the adjusting gear 607. The adjusting gear 607 runs along the tooth groove 608, drives the cross rod 605 and the cross bar 604 to move, thereby pushing the side of the folding bracket 602 equipped with the roller 603 to move, realizing the lifting adjustment of the folding bracket 602, and by rotating the limit knob 606, the limiting rod protruding from its surface is pushed against the rough part of the surface of the mounting disc to lock the position of the cross rod 605; after the adjustment is completed, turn on the conveyor track 2 and the main motor 308. The main motor 308 makes the hourglass roller shaft 306 rotate through the machine shaft 307. When the hourglass roller shaft 306 runs to the larger size at both ends, it will squeeze the rotating roller 305 downward, and at the same time squeeze the transmission shaft rod 304 downward to run. At the same time, it also makes the multi-axis curved rod 303 press the connecting shaft rod 309 downward to run. The connecting shaft rod 309 penetrates through the top of the cutter head frame 401, which will make the cutter head frame 401 drive the cutter head 404 downward to complete die-cutting. After that, when the hourglass roller shaft 306 runs to the narrower position in the middle, the cutter head frame 401 loses the downward pressure, and the return spring 403 returns to its original position, pushing the cutter head 404 back to its original position to prepare for the next die-cutting; when the cutter head 404 returns to the original position, the dust collector 501 is activated to start working, sucking away waste paper edges, paper fluff, etc. on the surface of the cutter head 404 through the air extraction joint 503. At the same time, the dust suction sticker 504 will stick the tiny impurities on the surface of the cutter head 404 to the surface of the dust suction sticker 504, keeping the surface of the cutter head 404 clean and facilitating the cutter head 404 to maintain an effective working state for a long time.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Technical staff in this industry should understand that the present invention is not limited by the above embodiments.
