Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, specifically a packaging paper die-cutting machine with a smoothing and pressing structure. Background Technology

[0002] With the development of the modern packaging industry, packaging paper die-cutting equipment has played an important role in improving production efficiency and ensuring product precision.

[0003] Patent CN222712961U discloses a die-cutting and creasing machine for packaging cartons, relating to the field of carton production technology. It includes a frame, an internal conveying mechanism for transporting cartons, lower pressure plates fixedly installed on the front and rear side walls of the frame, a positioning component for positioning the cartons fixedly installed on the inner wall of the frame, a discharge component for continuous carton feeding on the top surface of the frame, and a die-cutting and creasing mechanism fixedly installed on the top surface of the frame, with a pre-fixing mechanism on the movable part of the die-cutting and creasing mechanism. This patent improves the creasing efficiency of cartons by adding packaging cartons into the discharge component and then conveying them through the conveying mechanism. After the bottom cartons are conveyed, another group of cartons contacts the surface of the conveying mechanism under gravity, thus achieving continuous conveying of cartons one by one within the discharge component. As described above, existing packaging paper die-cutting machines generally use die-cutting blades to cut and groove cardboard or paper materials. However, they still have many shortcomings in actual production. Traditional die-cutting blades need to cut packaging paper, especially cardboard or multi-layer composite materials, during operation. After prolonged use, the blades become dull or slightly chipped, reducing cutting efficiency. They are secured with multiple bolts, making disassembly and replacement cumbersome and time-consuming. Furthermore, during die-cutting, the paper is prone to movement, edge flipping, or friction, leading to decreased cutting accuracy. Especially in high-speed continuous production, the paper drags or slips along the side of the blade, resulting in uneven edges on the finished product, affecting packaging aesthetics and assembly accuracy. Utility Model Content

[0015] 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.

[0016] Please see Figures 1-5 This utility model provides two technical solutions: Example 1: A packaging paper die-cutting machine with a smoothing and pressing structure, comprising: Workbench 1, with track groove blocks 4 fixedly connected to both sides of workbench 1; Die-cutting component 2 is movably connected to the inner wall of track block 4. Die-cutting component 2 is used to die-cut packaging paper. Die-cutting component 2 includes an outer block 21 movably connected to the top of track block 4. A round shaft 22 passes through the inner wall of the outer block 21. A handle is provided at the top of the round shaft 22. The round shaft 22 is movably connected to the inner wall of the outer block 21. A sliding plate 23 is fixedly connected to the bottom of the round shaft 22. The width of the sliding plate 23 is smaller than the width of the slot opened at the top of track block 4. Therefore, after rotating 90 degrees, the sliding plate 23 can be removed. The smoothing and pressing component 3 is fixedly connected to one side of the die-cutting component 2. The smoothing and pressing component 3 is used to effectively press the packaging paper.

[0017] Preferably, the bottom of the sliding plate 23 has a circular groove 24, and the inner wall of the circular groove 24 is movably connected to a universal ball bearing 25. Through the rotatable circular shaft 22 and the sliding plate 23 structure, the die-cutting blade 212 and its external telescopic rod 211 can be completely separated from the worktable 1 and the track block 4, thereby enabling quick disassembly and replacement of the die-cutting blade. The operator only needs to rotate the circular shaft 22 to rotate the sliding plate to remove the die-cutting blade and its accessories from the track block 4, without disassembling complex support structures or adjusting fixing bolts, significantly shortening the blade replacement time. This reduces operational difficulty and labor intensity, improves production continuity and equipment utilization, ensures quick blade replacement and convenient maintenance, and significantly enhances the flexibility and efficiency of the packaging production line.

[0018] Example 2 differs from Example 1 mainly in that: the packaging paper die-cutting machine with a smoothing and pressing structure has a groove 26 at the bottom of the outer block 21, an embedded ring 27 fixedly connected to the inner wall of the groove 26, a limit ring 28 movably connected to the inner wall of the embedded ring 27, and the inner wall of the limit ring 28 fixedly connected to the surface of the round shaft 22. A connecting plate 29 is fixedly connected to one side of the outer block 21, a top plate 210 is fixedly connected to one side of the connecting plate 29, a telescopic rod 211 is fixedly connected to the surface of the top plate 210, the surface of the telescopic rod 211 is connected to the hydraulic pump, a die-cutting blade 212 is fixedly connected to the bottom end of the telescopic rod 211, the top of the die-cutting blade 212 is the blade body, the bottom is the cutting edge, a guide rod 213 is fixedly connected to the top of the die-cutting blade 212, the top end of the guide rod 213 penetrates the top plate 210 and extends to the top of the top plate 210, and the smoothing and pressing assembly 3 packages The die-cutting assembly 2 includes a support plate 31 fixedly connected to one side, and one side of the support plate 31 fixedly connected to one side of the top plate 210 in the die-cutting assembly 2. A mounting bracket 32 ​​is fixedly connected to the surface of the support plate 31, and a pressing frame 33 is fixedly connected to the bottom of the mounting bracket 32. A spring 34 is fixedly connected to the top inside the pressing frame 33. A damper is installed inside the spring 34, and a moving block 35 is fixedly connected to the bottom of the spring 34. Grooves are provided on both sides of the moving block 35, which together with the protrusions on both sides of the inner wall of the pressing frame 33 form a limiting structure to prevent the moving block 35 from detaching from the pressing frame 33. A pressing roller 36 is rotatably connected to the inner wall of the moving block 35. A smoothing pressing assembly 3 is provided on one side of the die-cutting assembly 2. Through the support plate 31, mounting bracket 32, pressing frame 33, spring 34, moving block 35 and pressing roller 36, the die-cutting paper is uniformly pressed and smoothed. This pressing structure effectively prevents paper from flipping over and slipping laterally during die-cutting. Meanwhile, the bottom pressing roller 36 reduces frictional resistance, ensuring the die-cutting cutter doesn't move the paper as a whole, thus guaranteeing cutting accuracy and edge neatness. Furthermore, the use of multiple sets of rollers effectively smooths and presses the packaging paper throughout, ensuring work quality.

[0019] When the die-cutting blade 212 is working, the die-cutting assembly 2 is in a stable state and is stationary as a whole, and its surface is fastened with bolts.

[0020] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0021] During operation, a piece of packaging paper of appropriate thickness is placed on top of the workbench 1. The die-cutting assembly 2 and the smoothing and pressing assembly 3 are moved together, so that the bottom of the pressing roller 36 presses the top of the packaging paper. At this time, the spring 34 inside the pressing frame 33 pushes the moving block 35 and the pressing roller 36, smoothing and rolling the pressing roller 36. At the same time, the mounting frame 32 and the support plate 31 move along with the top plate 210 and the connecting plate 29. Simultaneously, the sliding plate 23 on the inner wall of the outer connecting block 21 moves, and the universal ball bearings 25 on the inner wall of the circular groove 24 roll on the inner surface of the track groove block 4, driving the die-cutting blade 212 to move to the cutting position. Then, the telescopic rod 211 extends. The die-cutting blade 212 moves down to die-cut the packaging paper. At the same time, the guide rod 213 slides along the top plate 210. Then, the above operation is repeated. When the die-cutting blade 212 is to be maintained, the handle at the top of the round shaft 22 is rotated, which rotates the round shaft 22 ninety degrees. The sliding plate 23 is rotated ninety degrees, and the limiting ring 28 rotates ninety degrees inside the embedded ring sleeve 27. The outer connecting block 21 and the round shaft 22 are pulled up as a whole, and the sliding plate 23 is separated from the track groove block 4. The die-cutting blade 212 can then be removed as a whole. After maintenance, it can be reinstalled. The operation can be reversed according to the above operation. When the device has finished working, the device is restored.
