Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-cutting technology for die-cutting machine sheet materials, specifically a die-cutting mechanism for a die-cutting machine. Background Technology
[0002] Die-cutting machines, also known as cutting machines or CNC punching machines, are mainly used for die-cutting (full cut, half cut), creasing, hot stamping, lamination, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic products, mobile phone pads, etc. Die-cutting machines use steel knives, hardware molds, and steel wire (or templates carved from steel plates) to apply a certain pressure through the printing plate to cut printed materials or cardboard into a certain shape.
[0003] The working principle of a die-cutting machine is to use a die-cutting blade, steel blade, metal mold, and steel wire (or a template engraved from a steel plate) to apply pressure through an imprinting plate, cutting printed materials or cardboard into a specific shape. Die-cutting involves pressing an entire printed product into a single graphic; creasing involves using steel wire to press marks or leave bending grooves on the printed material; hot stamping involves using two templates (yin and yang) and heating the mold to a certain temperature to imprint patterns or lettering with a three-dimensional effect onto the surface of the printed material; laminating involves applying one substrate to another; and removing the part other than the finished product is called waste removal. All of these can be collectively referred to as die-cutting technology.
[0004] In the prior art, publication number "CN219519451U" discloses a die-cutting mechanism for a die-cutting machine, including a drying chamber. An adjusting mechanism and a clamping mechanism are fixedly connected inside the drying chamber. The adjusting mechanism is located on the left and right sides of the clamping mechanism. The clamping mechanism includes a rotating component and a limiting component. The limiting component is located in front of the rotating component. The rotating component includes a second motor, which is fixedly connected to the center of the back of the drying chamber. A rotating rod is fixedly connected to the front of the second motor, and a first long plate is fixedly connected to the front of the rotating rod. A rectangular groove is formed inside the first long plate, and a second bidirectional threaded rod is rotatably connected inside the rectangular groove. This can surface coating preparation and processing device, by setting the clamping mechanism, can clamp cans of different sizes during the drying of the coating sprayed on the surface of the can, and also ensures that the clamped cans are dried more evenly in the later stages.
[0005] However, existing technologies still have significant shortcomings, such as:
[0006] In the aforementioned devices and existing technologies, during die-cutting, depending on the processing technology of the material sheet, the material sheet will be cut horizontally or in strips. Since the cutting blades are relatively sharp, the machine needs to be stopped and the cutting blades replaced after each material sheet is processed. The downtime will affect the die-cutting efficiency of batch materials, and the time required to replace the blades will also affect the die-cutting efficiency of the materials. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 This utility model provides a technical solution:
[0025] Example 1: A die-cutting mechanism for a die-cutting machine:
[0026] A die-cutting mechanism for a die-cutting machine includes a die-cutting frame 1, a transmission chain plate 3, a die-cutting table 4, and a dustproof shell 6. The transmission chain plate 3 is disposed between adjacent die-cutting frames 1, the die-cutting table 4 is mounted on the surface of the transmission chain plate 3, and the dustproof shell 6 is mounted on the top central area of the die-cutting frame 1.
[0027] A die-cutting sheet cutting and pressurizing guiding conveying unit is provided in the area of the dustproof shell 6. It is used to convey and cut the sheet entering the dustproof shell 6, while reducing the slippage of the die-cutting sheet during the cutting process.
[0028] The die-cutting sheet cutting, pressurizing, guiding and conveying unit includes a conveying section, which includes a side transmission chain 31. The side transmission chain 31 is installed on both sides of the transmission chain plate 3. Both ends of the inner side of the die-cutting frame 1 are equipped with drive gears 2, which mesh with the side transmission chain 31 for transmission.
[0029] The die-cutting sheet cutting, pressurizing, guiding, and conveying unit also includes a die-cutting section, which includes a three-jaw turntable 8. The three-jaw turntable 8 is disposed inside the dustproof shell 6. A tool holder 81 is installed at one end of the surface of the three-jaw turntable 8. A die-cutting blade 811 is installed at the bottom of the tool holder 81. A pressure guide roller 82 is rotatably installed at one end of the surface of the three-jaw turntable 8. A cutting pressure roller 83 is rotatably installed at one end of the surface of the three-jaw turntable 8. Circular cutters 831 are installed at equal intervals on the surface of the cutting pressure roller 83.
[0030] Positioning plates 51 are installed on both sides of the die-cutting table 4. A buffer seat 5 is installed at the bottom of the positioning plate 51. A vertical guide rail 52 is embedded in the inner wall of the dustproof shell 6. An electric drive turntable 53 is installed on the moving end of the vertical guide rail 52. The three-jaw turntable 8 is installed on the rotating end of the electric drive turntable 53.
[0031] In this embodiment, the three-jaw turntable 8 rotates to sort the slices and strips. After sorting, the selected tools are vertically calibrated. Once the tools are vertically calibrated, the vertical guide rail 52 is controlled to drive the three-jaw turntable 8 to descend vertically. When the tools are in place, they are cut at intervals on the surface of the die-cutting table 4 in conjunction with the movement of the die-cutting table 4, ensuring quick replacement of cutting tools and further ensuring the die-cutting efficiency of the materials.
[0032] Example 2:
[0033] Based on Embodiment 1, this embodiment takes into account that when the material sheet is long, when the material sheet is cut vertically, the internal stress at the end of the material sheet will loosen after one end is cut. In order to avoid the overall curling of the material sheet and affect the overall cutting effect of the material sheet, this embodiment is provided with a die-cutting tray pressure anti-warping unit to avoid the above-mentioned problem.
[0034] The dustproof shell 6 is provided with a die-cutting tray pressure anti-warping unit on one side.
[0035] The die-cutting tray pressure anti-warping unit includes an extension arm 7, which is installed on the side of the die-cutting table 4 near the die-cutting table 4. An anti-warping pressure roller 71 is installed between adjacent extension arms 7. A transverse guide rail 72 is embedded in the surface of the extension arm 7, and an anti-warping pressure roller 73 is installed on the moving end of the transverse guide rail 72.
[0036] In this embodiment, when the sheet material is conveyed through the die-cutting table 4, it will first come into contact with the second anti-warping pressure roller 73. The transverse guide rail 72 installed on the extension arm 7 will adjust the position of the second anti-warping pressure roller 73, and at the same time cooperate with the first anti-warping pressure roller 71 to achieve flat cutting in the sheet material cutting process, ensuring the cutting efficiency of the sheet material.
[0037] Working principle: The operator first stacks or stacks the sheet material to be die-cut on the surface of the die-cutting table 4. Then, the edge end of the sheet material is fixed by the external fastener to ensure the stability of the stack during the stacking process. Then, the motor inside the die-cutting frame 1 drives the drive gear 2 to rotate. When the drive gear 2 rotates, it meshes and drives the side transmission chain 31 to rotate in both directions. When the side transmission chain 31 drives the transmission chain plate 3 to rotate in the forward direction, the sheet material on the surface of the die-cutting table 4 will move into the dustproof shell 6 along with the transmission chain plate 3. After the sheet material is cut, the side transmission chain 31 is driven to rotate in the reverse direction to remove the die-cutting table 4 from the dustproof shell 6, completing the automatic feeding of the die-cutting sheet material and ensuring the die-cutting efficiency of the sheet material.
[0038] When the sheet material enters the dustproof housing 6, the operator can adjust the cutting tools according to the required processing technology of the sheet material. The operator can rotate the electric drive turntable 53. When the electric drive turntable 53 rotates, it will drive the three-jaw turntable 8 to rotate. The rotation of the three-jaw turntable 8 will sort the slices and strips. After sorting, the selected tools will be vertically calibrated. After the tools are vertically calibrated, the vertical guide rail 52 will be controlled to drive the three-jaw turntable 8 to descend vertically. When the tools are in place, they will cooperate with the movement of the die-cutting table 4 to cut the sheet material on the surface of the die-cutting table 4 at intervals, ensuring the quick change of cutting tools and further ensuring the die-cutting efficiency of the sheet material.
[0039] When the sheet material is being conveyed into the dustproof housing 6 for cutting, in order to avoid curling and warping of the sheet material during the cutting process, the sheet material will first contact the anti-warping pressure roller 2 73 when it is conveyed through the die-cutting table 4. The transverse guide rail 72 installed on the extension arm 7 will adjust the position of the anti-warping pressure roller 2 73, and at the same time cooperate with the anti-warping pressure roller 1 71 to achieve flat cutting of the sheet material during the cutting process, ensuring the cutting efficiency of the sheet material.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
