Description

Technical Field

[0001] The embodiments of this utility model relate to the field of die-cutting machine technology, specifically, to a die-cutting machine with high safety. Background Technology

[0002] Manual die-cutting machines are designed for small to medium batch production. Workers need to manually push the substrate and adjust its position, frequently bringing their hands close to the die. Automatic die-cutting machines require personnel to enter the equipment for maintenance or die replacement. The upper cutting blade may fall due to malfunction or gravity, leading to accidents. To improve safety, existing solutions typically equip manual machines with simple protective covers or baffles, relying on manual opening and closing. Automatic machines are equipped with safety door interlocks and emergency stop buttons. Manual safety features are often omitted due to workers' pursuit of efficiency and lack reliable emergency stops. Automatic equipment interlocks are easily removed unauthorizedly, sensor aging can cause misjudgments, and residual hydraulic / pneumatic forces are difficult to completely eliminate, still posing a risk of the cutting blade falling. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a high-safety die-cutting machine, which solves the technical problem in the prior art that the upper cutting blade assembly may fall due to gravity, causing accidental injury to personnel or damage to the equipment due to collision.

The download plate is lifted and positioned in the receiving groove. The download plate is configured to rise and push the paper close to the upper cutter assembly for cutting when the paper is being cut, and to descend and be received in the receiving groove when the paper is not being cut.

[0005] For example, in at least one embodiment of the present invention, a high-safety die-cutting machine is provided, which further includes: a lifting drive device, which is mounted on the frame and used to drive the download plate to move up and down.

[0006] For example, in a high-safety die-cutting machine provided in at least one embodiment of this utility model, the lifting drive device includes: The crankshaft, rotatably mounted on the frame, is used to drive the download plate to move up and down; The rotation drive component, mounted on the frame, is used to drive the crankshaft to rotate.

[0007] For example, in a high-safety die-cutting machine provided in at least one embodiment of the present invention, there are at least two crankshafts, which rotate synchronously to drive the download plate to move up and down.

[0008] For example, in at least one embodiment of the present invention, a high-safety die-cutting machine is provided, which has three crankshafts arranged in a triangular pattern. The three crankshafts are divided into a first crankshaft, a second crankshaft, and a third crankshaft, and further includes: The drive shaft is rotatably mounted on the frame and connected to the first crankshaft and the second crankshaft, and is used to drive the first crankshaft and the second crankshaft to rotate. The driven shaft is rotatably mounted on the frame and connected to the third crankshaft, used to drive the third crankshaft to rotate; The driving shaft and the driven shaft are arranged parallel and spaced apart.

[0009] For example, in a high-safety die-cutting machine provided by at least one embodiment of the present invention, a first gear is provided on the drive shaft, and a second gear that meshes with the first gear is provided on the driven shaft; The rotation drive component is mounted on the frame, and its drive end is connected to the drive shaft.

[0010] For example, in at least one embodiment of the present invention, a high-safety die-cutting machine is provided, wherein the download plate has a mounting groove and the crankshaft has a cylindrical connecting part; the high-safety die-cutting machine further includes: The connector is set in the mounting slot.

[0011] For example, in a high-safety die-cutting machine provided in at least one embodiment of the present invention, the connecting piece is detachably disposed in the mounting groove.

[0012] For example, in a high-safety die-cutting machine provided in at least one embodiment of the present invention, the connector also has a connecting block, and the connecting block is detachably connected to the download plate by fasteners.

[0013] For example, in a high-safety die-cutting machine provided in at least one embodiment of this utility model, the connecting block and the column are detachably connected.

[0014] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the upper cutting blade assembly is fixed to the frame and its position remains unchanged, effectively preventing the need for a drive mechanism or locking structure to maintain the upper cutting blade assembly at a high position during non-working states, such as machine shutdown for maintenance or equipment standby. If the mechanism malfunctions, such as drive failure or loosening of the lock, the upper cutting blade assembly may fall due to gravity, causing accidental injury or equipment damage.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figure 1 As shown, it illustrates a highly secure die-cutting machine according to one embodiment of the present invention, which is mainly used in production scenarios such as packaging and printing that require paper to be cut into shapes.

[0024] The frame 100 has a receiving groove 110, which provides space for the lifting and lowering of the download plate 300. In this design, the side wall of the receiving groove 110 has a sliding groove for the lifting and lowering of the download plate 300. Alternatively, a slide rail or other type can be used, as long as it provides a sliding base; no restrictions are placed here. The upper surface of the download plate 300 is used to place the paper to be cut. The upper cutter assembly 200 is fixedly installed on the frame 100 and located directly above the receiving groove 110 for cutting the paper.

[0025] The lifting drive device 400 is used to drive the download plate 300 to lift. The lifting drive device 400 mainly includes a crankshaft 410, a rotation drive component 420, a drive shaft 430, a driven shaft 440, and gears. like Figure 2 and Figure 3 As shown, there are three crankshafts 410 arranged in a triangle: a first crankshaft 411, a second crankshaft 412, and a third crankshaft 413. All are rotatably mounted on the frame 100, and each crankshaft 410 has a cylindrical connecting portion 414. A drive shaft 430 and a driven shaft 440 are rotatably mounted on the frame 100, parallel to and spaced apart. The drive shaft 430 is directly connected to the first crankshaft 411 and the second crankshaft 412, enabling them to rotate synchronously. The driven shaft 440 is directly connected to the third crankshaft 413, enabling it to rotate. A first gear 450 is fixed on the drive shaft 430, and a second gear 460, meshing with the first gear 450, is fixed on the driven shaft 440. Synchronous rotation of the drive shaft 430 and the driven shaft 440 is achieved through gear meshing. A rotation drive component 420 is mounted on the frame 100, with its drive end connected to the drive shaft 430, providing power for the rotation of the drive shaft 430.

[0026] The connector 500 is installed in the mounting slot 310 of the download plate 300 and is used to connect the crankshaft 410 and the download plate 300. The connector 500 includes a column 520 and a connecting block 510. The column 520 can be rotatably engaged with the cylindrical connecting part 414 of the crankshaft 410. The connecting block 510 is detachably connected to the download plate 300 by fasteners (such as bolts, screws, etc.), and the connecting block 510 is also detachably connected to the column 520. As one embodiment, the two ends of the column 520 can be threadedly connected to the column 520.

[0027] Specifically, in the non-cutting state, the download plate 300 is lowered by the lifting drive device 400 and completely housed in the receiving slot 110 of the frame 100. The paper to be cut is not placed or is in a waiting state, and the upper cutter assembly 200 remains stationary.

[0028] For cutting preparation, place the paper to be cut on the upper surface of the download plate 300, ensuring that the paper is neatly arranged.

[0029] During the cutting operation, the rotating drive component 420 is activated, and its driving end drives the drive shaft 430 to rotate. The drive shaft 430 drives the driven shaft 440 to rotate synchronously through the meshing of the first gear 450 and the second gear 460 on the driven shaft 440. The drive shaft 430 simultaneously drives the first crankshaft 411 and the second crankshaft 412 to rotate, and the driven shaft 440 drives the third crankshaft 413 to rotate. The three crankshafts 410 rotate synchronously in a triangle to ensure that the download plate 300 is subjected to balanced force. When the crankshaft 410 rotates, its cylindrical connecting part 414 drives the connecting part 500 to rise and fall through the column 520 of the connecting part 500. The connecting part 500 further drives the download plate 300 to rise along the receiving groove 110. During the rising process, the download plate 300 pushes the paper on the upper surface closer to the upper cutter assembly 200 above until the paper contacts the upper cutter assembly 200 and the cutting is completed.

[0030] After cutting, the rotating drive 420 drives the drive shaft 430 to rotate in the opposite direction, causing the download plate 300 to descend and be re-accommodated in the receiving groove 110, and the cut paper is taken out, completing one processing cycle.

[0031] In die-cutting machines, the upper cutting blade assembly 200 typically integrates rigid components such as the die and blade holder, which are relatively heavy and possess sharp cutting capabilities. If a design is adopted where the upper cutting blade assembly 200 descends, in non-working states, such as when the machine is stopped for maintenance or the equipment is in standby mode, it needs to rely on a drive mechanism or locking structure to maintain its high position. If the mechanism fails, such as drive failure or loosening of the lock, the upper cutting blade assembly 200 may fall due to gravity, causing accidental injury to personnel or damage to the equipment. In this embodiment, the upper cutting blade assembly 200 is fixed to the frame 100 and its position remains unchanged. Only the download plate 300 moves up and down. When not in operation, the download plate 300 can be directly lowered and stored in the receiving slot 110, improving safety.

[0032] In addition, the upper cutting blade assembly 200, due to its need to support the cutting die and ensure cutting rigidity, is significantly heavier than the download plate 300, which is only used to support paper. If an upper cutting blade lowering design is adopted, a heavy-duty drive mechanism (such as a high-power motor and high-strength transmission components) is required to drive the heavy components to rise and fall stably. This would not only increase the manufacturing cost of the equipment but also lead to increased energy consumption and faster wear of components due to the large drive load (such as shortened lifespan of transmission gears and bearings).

[0033] In this solution, the lifting drive device 400 (crankshaft 410, rotation drive component 420, etc.) only needs to drive the lightweight download plate 300, which greatly reduces the drive load. On the one hand, smaller power rotation drive component 420 and lighter crankshaft 410 and other components can be selected to simplify the overall transmission structure and reduce manufacturing and procurement costs. On the other hand, low-load operation can reduce the wear of transmission components, extend the service life of equipment, and reduce daily operating energy consumption.

[0034] Furthermore, in this embodiment, the lifting structure of the download plate 300 enables active demolding through its active reset, preventing the paper from sticking to the upper cutter. In traditional upper cutter-downward designs, after cutting, the upper cutter needs to rise and the spring cotton installed on the upper cutter assembly 200 to detach the paper, but there is still a possibility that it cannot detach completely. In this solution, after cutting, the download plate 300 will actively lower and reset. At this time, the paper is still placed on the upper surface of the download plate 300. The downward movement of the download plate 300 can generate a slight downward traction force on the paper, causing the paper to detach from the upper cutter synchronously with the download plate 300.

[0035] Furthermore, in this embodiment, the advantage of detachably connecting the connector 500 and the download plate 300 is that, as a force-transmitting wear part, the connector 500, with its column 520 easily worn and its connecting block 510 potentially deformed, eliminates the need to disassemble large components such as the crankshaft 410 and the download plate 300. Only the fasteners need to be removed for individual replacement or repair, avoiding the need to replace the entire download plate 300 due to the failure of a small component. Moreover, troubleshooting is quick; when the download plate 300 is stuck or tilted, disassembling the connector 500 can determine whether it is the problem, shortening the troubleshooting time and ensuring the operating efficiency of the equipment. It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
