Description

Technical Field

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

[0002] Die-cutting waste removal is an important process in post-printing processing and is widely used in many industries such as packaging, labeling, and electronics.

[0003] Die-cutting waste removal is the process of cutting and separating printed materials or other materials into pre-designed shapes and sizes using a die, and removing unwanted waste parts.

[0004] Traditional die-cutting waste removal devices can only press down and pick up materials of a single specification. The pressure frame is not easy to adjust. If materials of different specifications are loaded, a corresponding pressure frame needs to be installed so that the die-lifting component can work with the pressing component to lift up the corresponding material part and then transfer it manually, which is quite inconvenient to use. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a die-cutting waste removal device.

[0007] (II) Technical Solution

Support legs are provided at the four corners below the worktable. A die-lifting component for lifting materials is provided in the middle of the upper part of the worktable. A grid adapted to the output end of the die-lifting component is also provided on the worktable. The pressing component includes a support column, a top plate, a first lifting device, and a pressure plate. Support columns are provided at the four corners above the worktable, and the four corners below the top plate are connected to the support columns.

The limiting component includes a second lifting device, a support frame, a spacing adjustment component, and a limiting plate. The second lifting device is configured in four evenly arranged groups, with the output ends of the four groups passing through the top plate and connected to the support frame. Two symmetrically arranged limiting plates are provided below the support frame. A spacing adjustment component for adjusting the position of the two groups of limiting plates is also provided on the support frame.

[0009] To facilitate adjustment of the spacing between the two sets of pressure plates, this utility model improves upon the following: the spacing adjustment assembly includes a worm gear, a worm, a cover, a motor, forward and reverse threaded rods, and mounting seats. A cover is provided on one side of the support frame, and a worm and two sets of worm gears are housed within the cover. The worm meshes with the two sets of worm gears. Two sets of forward and reverse threaded rods are also rotatably arranged within the support frame, with one end of each rod passing through the support frame and the cover and connecting to the center of the worm gear. Two sets of symmetrically arranged mounting seats are slidably arranged within the support frame. A limiting plate is connected to the mounting seats via a connector, and the mounting seats are located on the left and right sides of the pressure plate.

[0010] To facilitate the disassembly and assembly of the pressure plate, this utility model is improved by including a first magnetic absorbing piece and a second magnetic absorbing piece as the connecting member, a slot is provided below the mounting base, the first magnetic absorbing piece is embedded in the slot, and a second magnetic absorbing piece is provided on the limiting plate to be magnetically connected to the first magnetic absorbing piece.

[0022] 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.

[0023] Please see Figures 1-4 A die-cutting waste removal device includes a worktable 1, support legs 2, a pressing assembly, a die-lifting assembly, and a limiting assembly. Support legs 2 are located at the four lower corners of the worktable 1. A die-lifting assembly for lifting materials is located in the middle upper part of the worktable 1. A grid 3 adapted to the output end of the die-lifting assembly is also provided on the worktable 1. The pressing assembly includes support columns 4, a top plate 5, a first lifting device 6, and a pressure plate 7. Support columns 4 are located at the four upper corners of the worktable 1, and the four lower corners of the top plate 5 are connected to the support columns 4. The first lifting device... 6 passes through the center of the top plate 5 and is connected to the pressure plate 7. The pressure plate 7 is located above the mold-raising assembly. The limiting assembly includes a second lifter 8, a support frame 9, a spacing adjustment assembly, and a limiting plate 10. The second lifter 8 is configured as four groups evenly arranged. The output ends of the four groups of second lifters 8 pass through the top plate 5 and are connected to the support frame 9. Two groups of symmetrically arranged limiting plates 10 are provided below the support frame 9. A spacing adjustment assembly that drives the position adjustment of the two groups of limiting plates 10 is also provided on the support frame 9.

[0024] The support leg 2 provides stable support for the worktable 1, and the worktable 1 provides stable support for the mold-lifting assembly. The mold-lifting assembly includes a cylinder and an ejector pin, which are used to lift the corresponding part of the material in conjunction with the grid 3. The worktable 1 is often also equipped with a translation device that drives the material to move. The above structure is a conventional structure on the market. This article aims to provide a die-cutting waste removal device that can adaptively adjust the pressure spacing so as to ensure that the mold-lifting assembly and the pressing assembly can stably lift the material of the corresponding specification part, while other processing parts are restricted to the grid 3.

[0025] When the material is in the corresponding position, the spacing adjustment component is activated, and the two sets of limit plates 10 move towards each other. The ejected part of the material is located between the two sets of limit plates 10 and the two sets of positive and negative toothed rods 15. The four sets of second lifting devices 8 are activated. The second lifting devices 8 are pneumatic cylinders. The synchronous movement of the four sets of pneumatic cylinders can be controlled by a synchronization valve or a PLC control system. The first lifting device 6 is activated. The first lifting device 6 is also pneumatic cylinder. The first lifting device 6 drives the pressure plate 7 to contact the ejected part of the material. The mold-lifting component is activated. The ejector pin of the mold-lifting component drives the corresponding part of the material to be lifted.

[0026] The spacing adjustment assembly includes a worm gear 11, a worm 12, a cover 13, a motor 14, forward and reverse toothed rods 15, and mounting bases 16. A cover 13 is provided on one side of the support frame 9. The cover 13 houses the worm 12 and two sets of worm gears 11, with the worm 12 meshing with the two sets of worm gears 11. Two sets of forward and reverse toothed rods 15 are also rotatably arranged within the support frame 9. One end of each forward and reverse toothed rod 15 passes through the support frame 9 and the cover 13 and is centrally connected to the worm gears 11. Two symmetrically arranged mounting bases 16 are slidably arranged within the support frame 9. The limiting plate 10 is connected to the mounting bases 16 via connectors. The mounting bases 16 are located on the left and right sides of the pressure plate 7. The motor 14 is started. Since the motor 14 is a servo motor, it can precisely control the rotation angle and speed. The motor 14 drives the worm 12 to rotate, and the worm 12 meshes with the two sets of worm gears 11, causing the two sets of worm gears 11 to rotate synchronously. The rotation of the worm gear 11 drives the rotation of the positive and negative thread rod 15 connected to its center. Due to the special thread design of the positive and negative thread rod 15, when the positive and negative thread rod 15 rotates, the two sets of symmetrically arranged mounting seats 16 that are slidably set in the support frame 9 will move in a straight line relative to or away from the positive and negative thread rod 15. The connecting parts include a first magnetic suction piece 17 and a second magnetic suction piece 18. A slot is provided below the mounting seat 16, and the first magnetic suction piece 17 is embedded in the slot. The limiting plate 10 is provided with a second magnetic suction piece 18 that is magnetically connected to the first magnetic suction piece 17. The mounting seat 16 is connected to the limiting plate 10 through the connecting parts (first magnetic suction piece 17 and second magnetic suction piece 18). Therefore, the movement of the mounting seat 16 will drive the limiting plate 10 to move, thereby realizing the precise adjustment of the distance between the two sets of limiting plates 10 to adapt to the size requirements of materials of different specifications and play a precise limiting role for materials. The limiting plate 10 can be obtained by 3D printing.

[0027] The grid 3 serves as an auxiliary support and positioning element. It is compatible with the output end of the die-cutting assembly and is fixed to the worktable 1 by bolts 19, ensuring the stability of the die-cutting process. The height to which the die-cutting assembly lifts the material meets the process requirements for die-cutting and waste removal, facilitating subsequent die-cutting and waste removal operations.
