Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, specifically to a die-cutting mechanism for a die-cutting machine. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are mainly used for die-cutting (full or partial cut), creasing, and hot stamping of trademarks, cardboard boxes, and greeting cards in the packaging and decoration industries of some non-metallic materials, self-adhesive labels, double-sided adhesives, electronic and mobile phone pads, and product packaging and decoration. They are important equipment for post-printing packaging processing and forming. The principle is to use a template carved from steel knives, hardware molds, steel wires, or steel plates, and apply a certain pressure through the imprinting plate to cut the printed materials or cardboard into a certain shape.

[0003] Existing die-cutting machines often leave waste materials after die-cutting, such as small waste materials inside holes and edge scraps, which can easily cause batch quality problems, requiring additional rework and increasing costs. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a die-cutting mechanism for a die-cutting machine, which has the advantage of easy waste removal. It solves the problem that waste materials after die-cutting by existing die-cutting machines, such as small waste materials inside holes and edge scraps, are likely to remain inside the material holes. The waste materials remaining in the holes can easily cause batch quality problems, requiring additional rework and increasing costs.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a die-cutting mechanism for a die-cutting machine, comprising a main body assembly, wherein the main body assembly includes: The operating table has a die-cutting mechanism on its top; The operating table and the die-cutting mechanism are equipped with a cleaning component, which includes: The bracket is fixedly connected to the top of the operating table; A connecting plate is disposed on the outer wall of the bracket; Elastic sheets are symmetrically and fixedly connected to the outer wall of the connecting plate; A guide plate is symmetrically and slidably connected to the top of the operating table; The frame is fixedly connected to the top of the operating table; The drive mechanism is disposed on the guide plate and the frame; A controller is mounted on the operating table and is electrically connected to the die-cutting mechanism and the drive mechanism.

[0006] Preferably, the drive mechanism includes: Cavities are symmetrically formed at the bottom of the frame; A bidirectional lead screw passes through and is rotatably connected to the cavity; A threaded block is symmetrically and threadedly connected to the outside of the bidirectional lead screw. The threaded block is slidably connected to the inside of the cavity. The bottom end of the threaded block is fixedly connected to the guide plate. The motor is located on the outer wall of the frame, and the output shaft of the motor is fixedly connected to one end of the bidirectional lead screw. The motor is electrically connected to the controller.

[0007] Preferably, the elastic sheet is provided with arc-shaped protrusions, and the protrusions are made of a soft, elastic material.

[0008] Preferably, the bracket and the connecting plate are provided with a disassembly assembly, the disassembly assembly comprising: A groove is formed at the top of the bracket; The connecting block is fixedly connected to the outer wall of the connecting plate; Bolts are threadedly connected to the groove and the connecting block.

[0009] Preferably, the inner wall of the cavity and the facing surface of the threaded block are both provided with telescopic shells.

[0010] Preferably, a collection frame is provided at the bottom of the operating table, and the collection frame is located below the elastic sheet.

[0011] (III) Beneficial Effects Compared with the prior art, the present invention provides a die-cutting mechanism for a die-cutting machine, which has the following beneficial effects: This die-cutting mechanism offers the advantage of easy waste removal. First, the width data of the die-cutting material is input into the controller. The controller then adjusts the spacing of the guide plates via the drive mechanism to prevent skewing during material feeding and die-cutting. After die-cutting, the material is conveyed to the support below. The elastic sheet, due to the material's obstruction, undergoes slight compression deformation. Simultaneously, the tilt angle ensures that the elastic sheet accurately "locks" into the subsequent die-cutting holes as the material continues to move. Once the bottom of the elastic sheet is fully inside the hole, the compressed elastic protrusion releases its restoring force, pushing the waste material out of the hole and removing it from the material surface, achieving automatic waste removal. This solves the problem of existing die-cutting machines leaving waste after die-cutting, such as small pieces of waste material inside the holes and edge residue, which can easily cause batch quality problems and require additional rework, increasing costs.

[0014] 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.

[0015] Example 1 See Figure 1-4A die-cutting mechanism for a die-cutting machine includes a main body component 1, which includes: an operating table 11 with a die-cutting mechanism 12 mounted on its top; a cleaning component 2 mounted on the operating table 11 and the die-cutting mechanism 12, the cleaning component 2 including: a bracket 21 fixedly connected to the top of the operating table 11; a connecting plate 22 disposed on the outer wall of the bracket 21; an elastic sheet 23 symmetrically and fixedly connected to the outer wall of the connecting plate 22; a guide plate 24 symmetrically and slidably connected to the top of the operating table 11; a frame 25 fixedly connected to the top of the operating table 11; a driving mechanism 26 disposed on the guide plate 24 and the frame 25; and a controller 27 disposed on the operating table 11, the controller 27 being electrically connected to the die-cutting mechanism 12 and the driving mechanism 26. The drive mechanism 26 includes: a cavity 261 symmetrically formed at the bottom of the frame 25; a bidirectional lead screw 262 passing through and rotatably connected to the cavity 261; a threaded block 263 symmetrically and threadedly connected to the outside of the bidirectional lead screw 262, the threaded block 263 slidably connected to the inside of the cavity 261, and the bottom end of the threaded block 263 fixedly connected to the guide plate 24; and a motor 264 disposed on the outer wall of the frame 25, the output shaft of the motor 264 fixedly connected to one end of the bidirectional lead screw 262, and the motor 264 electrically connected to the controller 27. The elastic sheet 23 has arc-shaped protrusions made of a soft, elastic material.

[0016] In operation, the operator first inputs the width data of the die-cutting material into the controller 27. The controller 27 then adjusts the spacing of the guide plates 24 via the drive mechanism 26 to prevent skewing during material feeding and die-cutting. The controller 27 starts the motor 264, which drives the bidirectional lead screw 262 to rotate. The threaded block 263 connected to the bidirectional lead screw 262 moves the guide plates 24 until the spacing of the guide plates 24 is adjusted to be slightly larger than the width of the material. The material is guided by the guide plates 24 into the die-cutting mechanism 12 for die-cutting. The die-cut material is then conveyed to the underside of the bracket 21. Due to the tilt of the elastic sheet 23, the elastic sheet 23 undergoes slight compression deformation due to the obstruction of the material. At the same time, the tilt angle ensures that the elastic sheet 23 can accurately "lock" into the subsequent die-cutting holes as the material continues to move. When the bottom end of the elastic sheet 23 is fully inserted into the hole, the compressed elastic protrusion releases the restoring force, pushing the waste material out of the hole and removing it from the material surface, thus achieving automatic waste removal. The elastic sheet 23 can be made of polyurethane board. The arc-shaped protrusions on the elastic sheet 23 avoid right angles, sharp angles or points, reduce sharp contact, increase the buffer area and reduce local pressure. The protrusions can be made of silicone material, which utilizes the elasticity of the material itself to buffer the contact force. It is especially suitable for easily scratched materials such as paper and film, and reduces damage to the surface and edges of the material.

[0017] The aforementioned die-cutting mechanism 12 employs conventional technology, such as a cylinder using compressed air to push the piston rod, causing the upper die holder to rise and fall vertically. The upper die holder is used to fix the punching tool, and the lower die holder is used to fix the lower die pad, buffering the punching force and protecting the tool. When the cylinder drives the upper die holder to move up and down, the punching tool performs die-cutting. The die-cutting mechanism 12, in conjunction with a roller and positioning pin, conveys the material. The roll material is conveyed as the roller rotates. When the positioning hole on the material aligns with the positioning pin, the roller pauses, and the die-cutting mechanism 12 presses down to punch; after punching is completed, the positioning pin disengages, and the roller continues to rotate and convey the material. As long as the die-cutting effect on the material can be achieved, the specific structure will not be described in detail here.

[0018] Example 2 An auxiliary function has been added based on Embodiment 1.

[0019] See Figure 1-4 The bracket 21 and the connecting plate 22 are provided with a disassembly assembly 3. The disassembly assembly 3 includes: a groove 31, formed on the top of the bracket 21; a connecting block 32, fixedly connected to the outer wall of the connecting plate 22; and a bolt 33, threadedly connected to the groove 31 and the connecting block 32. A telescopic shell 5 is provided on the inner wall of the cavity 261 and the facing surface of the threaded block 263. A collection frame 4 is provided at the bottom of the operating table 11, located below the elastic sheet 23.

[0020] By unscrewing bolt 33, the connecting block 32, along with the connecting plate 22 and the elastic plate 23, can be removed from the bracket 21. This allows for easy replacement of elastic plates 23 of different sizes and spacings to accommodate variations in the size or spacing of the die-cutting holes, improving the equipment's versatility. When the threaded block 263 moves the guide plate 24 closer together, the telescopic shell 5 fixed to the facing surface of the threaded block 263 retracts, while the outer fixed telescopic shell 5 extends. When the threaded blocks 263 move away from each other, the telescopic shell 5 fixed to the facing surface of the threaded block 263 extends, while the outer fixed telescopic shell 5 retracts. The telescopic shell 5 shields the cavity 261, preventing foreign objects from entering and affecting the normal operation of the bidirectional lead screw 262 and the threaded block 263. After the elastic plate 23 pushes the waste material from the material holes downwards, the waste falls into the collection frame 4, facilitating easy cleaning of the collection frame 4 after the machine is stopped.
