Description

Technical Field

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

[0002] Die-cutting machines use steel blades, metal molds, and steel wire (or templates carved from steel plates) to apply pressure through an imprinting plate, cutting printed materials or cardboard into specific shapes. Corrugated cardboard is made from paper through a series of precision operations to create a corrugated shape. Corrugated cardboard is widely used in the packaging industry, such as in cartons and boxes. These packaging products need to be customized according to different product sizes and shapes. Die-cutting machines can accurately cut out the required shapes and sizes, ensuring the quality and adaptability of the packaging products.

[0003] Existing die-cutting machines have only one die-cutting station and can only die-cut one product at a time. For example, the anti-loosening and offset corrugated cardboard edge-trimming die-cutting machine disclosed in CN217861728U uses a hydraulic cylinder to drive the cutter for cutting, and uses an extrusion plate and spring to fix the corrugated cardboard to prevent it from shifting during the cutting process. However, since there is only one die-cutting station, other products have to wait while the die-cutting machine is cutting one product, which limits the improvement of production efficiency.

[0004] Therefore, it is necessary to invent a die-cutting machine for corrugated cardboard processing to solve the above problems. Utility Model Content

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-7 The diagram shows a die-cutting machine for corrugated cardboard processing, comprising a frame 1, a first die holder 3, and a second die holder 4. A base 2 is positioned above the frame 1, and the first and second die holders 3 and 4 are positioned above the base 2. A first cylinder 5 is positioned above the first die holder 3 and is located on the frame 1. A support plate 6 is positioned at the output end of the first cylinder 5, and a die-cutting blade 7 is positioned below the support plate 6. An electric push rod 8 is positioned on one side of the top of the frame 1, and a slide 9 is positioned at the output end of the electric push rod 8. A slide rail 10 is positioned below the slide 9, and a groove 11 is formed at the contact point between the slide 9 and the slide rail 10. A further groove 11 is positioned below the slide 9. There is a second cylinder 13, the output end of which is connected to a second support plate 14. A second die-cutting blade 15 is set at the bottom of the second support plate 14. Sleeves 17 are set on both the left and right sides of the first support plate 6 and the second support plate 14. A sliding rod 18 is set inside the sleeve 17. A spring 19 is sleeved on the sliding rod 18. Guide posts 20 are set at the front and rear ends of the sleeve 17 and the sliding rod 18. The guide posts 20 are slidably connected to the first support plate 6 and the second support plate 14. A pressure plate 21 is set at the bottom end of the guide posts 20 and the sliding rod 18. One end of the spring 19 is connected to the bottom surface of the sleeve 17, and the other end of the spring 19 is connected to the top surface of the pressure plate 21.

[0028] The first mold base 3 is arranged parallel to one side of the second mold base 4. The first mold base 3 and the second mold base 4 have the same structural design. The first die cutter 7 is arranged directly above the first mold base 3, and the second die cutter 15 is arranged directly above the second mold base 4. There are two slide rails 10, which are located at the upper and lower ends of the frame 1. The slide rails 10 are slidably connected to the slide grooves 11. The top of the frame 1 is provided with a guide rod 12, which extends through to the slide base 9. The guide rod 12 is slidably connected to the slide base 9.

[0031] The design of the through groove 16 and the collection groove 22 simplifies the waste disposal process, reduces the tediousness of manual cleaning, and helps to maintain a clean and safe working environment. The waste generated during the die-cutting process can fall directly into the collection groove 22 below the base 2 through the through groove 16, realizing the centralized collection of waste.

[0032] Working principle of this utility model:

[0033] Refer to the instruction manual appendix Figure 1-3 When using this utility model, first place the corrugated cardboard to be die-cut on the first die holder 3 and the second die holder 4 respectively, adjust the initial position of the first cylinder 5 and the second cylinder 13 so that the first die-cutting blade 7 and the second die-cutting blade 15 are respectively above the first die holder 3 and the second die holder 4, but do not contact the cardboard. Then, according to the usage requirements, the first cylinder 5 and the second cylinder 13 can be started at the same time, so that the first support plate 6 and the second support plate 14 can respectively drive the first die-cutting blade 7 and the second die-cutting blade 15 to move downward a small distance.

[0034] Refer to the instruction manual appendix Figure 4-7When using this utility model, the pressure plate 21 will press tightly against the cardboard due to the action of the spring 19, fixing the cardboard in place. The cylinder will continue to be activated, causing the first die-cutting blade 7 and the second die-cutting blade 15 to cut into the corrugated cardboard on the first die holder 3 and the second die holder 4 respectively, completing the die-cutting action. After the die-cutting is completed, the first die-cutting blade 7 and the second die-cutting blade 15 will return to their initial positions. At this time, the waste generated during the die-cutting process will fall directly into the collection groove 22 below the base 2 through the through groove 16, and the die-cut finished products on the first die holder 3 and the second die holder 4 will be taken out to prepare for the next batch of corrugated cardboard to be die-cut.
