Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box production technology, and in particular to a corrugated paper cutting device for corrugated cardboard box production. Background Technology

[0002] In the corrugated cardboard box production process, the corrugated paper cutting process has a significant impact on the subsequent box forming quality. Currently available corrugated paper cutting devices often suffer from insufficient feeding accuracy, relying heavily on manual pushing of the corrugated paper. This not only involves high labor intensity but also easily leads to cutting position deviations due to operational errors, resulting in dimensional deviations and material waste. Although some equipment is equipped with an automatic feeding structure, the design of the corrugated paper holding mechanism is unreasonable. During cutting, the paper is easily warped and displaced by the blade force, affecting the flatness of the cut. At the same time, the cutting blades of traditional devices are cumbersome to disassemble and assemble, and replacing worn blades or adapting to different cutting requirements consumes a lot of time. This makes it difficult to meet the high efficiency and high precision requirements of modern cardboard box production, bringing certain adverse effects to the user experience. In order to overcome the shortcomings of existing technologies, we propose a corrugated paper cutting device for corrugated cardboard box production. Utility Model Content

[0003] The main objective of this invention is to provide a corrugated paper cutting device for corrugated box production, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A corrugated paper cutting device for corrugated box production includes a cutting table. A servo motor is detachably connected to one side of the cutting table, and the output shaft of the servo motor is detachably connected to a threaded rod. Two fixing plates are symmetrically fixed at the upper end of the cutting table, and guide rods are fixedly connected inside the fixing plates. A moving block is threadedly connected to the outer surface of the threaded rod. A push plate is fixedly connected to the upper end of the moving block, and sliders are fixedly connected to both ends of the push plate. A cutting groove is formed on the surface of the cutting table. A fixing frame is fixedly connected to the upper end of the cutting table, and two electric push rods are detachably connected to the upper end of the fixing frame. The output ends of the electric push rods are detachably connected to... A connecting plate is provided, and a first fixing block is fixedly connected to both ends of the connecting plate. A rectangular groove is opened on the inner surface of both sides of the fixing frame, and a first fixing rod is fixedly connected in the rectangular groove. Multiple second fixing blocks are fixedly connected to both sides of the connecting plate. A second fixing rod is inserted through the second fixing block, and a limit block is fixedly connected to the top of the second fixing rod. A pressure plate is fixedly connected to the lower end of the second fixing rod, and a spring is sleeved on the outer surface of the second fixing rod between the second fixing block and the pressure plate. A knife holder is installed at the lower end of the connecting plate, and a cutting knife is installed in the knife holder. A bolt for fixing the cutting knife is provided on one side of the knife holder.

[0005] Preferably, the movable block has a threaded hole that matches the threaded rod, and the movable block is threadedly connected to the outer surface of the guide rod through the threaded hole, and the slider is slidably connected to the outer surface of the guide rod.

[0006] Preferably, a rubber anti-slip pad is fixedly connected to the lower end of the pressure plate, and the lower surface of the rubber anti-slip pad is provided with anti-slip texture. The number of pressure plates is the same as the number of second fixing blocks, and the pressure plates are evenly distributed along the length direction of the connecting plate.

[0007] Preferably, the blade holder has a mounting groove adapted to the cutting blade, the back of the cutting blade is embedded in the mounting groove, and a threaded hole adapted to the bolt is provided on one side of the blade holder. The threaded hole extends into the mounting groove, and the bolt is fixed to the back of the cutting blade through the threaded hole.

[0008] Preferably, the first fixing block has a through hole that matches the first fixing rod, the first fixing block is sleeved on the outer surface of the first fixing rod through the through hole, and the first fixing block and the first fixing rod are slidably connected.

[0009] Compared with the prior art, the present invention has the following beneficial effects: This corrugated paper cutting device for corrugated box production uses a servo motor to drive a threaded rod to rotate. This, combined with a guide rod that guides and limits the moving block, allows the push plate to smoothly and precisely move the corrugated paper to a preset position directly above the cutting slot. This replaces manual feeding and effectively avoids positional deviations caused by manual operation. Simultaneously, during the downward movement of the connecting plate, the pressure plate first contacts the corrugated paper. The elastic pressure generated by the compressed spring ensures the pressure plate tightly holds the corrugated paper, preventing warping and displacement during cutting. This significantly improves cutting dimensional accuracy, reduces material waste caused by inaccurate positioning, and lowers production losses and costs.

[0010] This corrugated paper cutting device for corrugated box production uses an electric push rod to move the connecting plate downwards. Combined with the sliding cooperation of the first fixing block along the first fixing rod, it ensures that the connecting plate and the cutting blade always move stably in the vertical direction, avoiding problems such as rough edges and paper breakage caused by the cutting blade tilting. This ensures consistent cutting quality. The cutting blade is embedded in the blade holder mounting slot and secured with bolts, making disassembly and assembly convenient. When the cutting blade wears out or needs to be replaced with a different size blade, there is no need to disassemble the entire blade holder, which greatly shortens maintenance time and reduces operating difficulty. At the same time, it is adaptable to various corrugated paper cutting needs, improving the versatility of the device and production efficiency. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a corrugated paper cutting device for corrugated cardboard box production includes a cutting table 1. A servo motor 2 is detachably connected to one side of the cutting table 1. A threaded rod 3 is detachably connected to the output shaft of the servo motor 2. Two fixing plates 4 are symmetrically fixed to the upper end of the cutting table 1. A guide rod 5 is fixedly connected inside the fixing plate 4. A moving block 6 is threadedly connected to the outer surface of the threaded rod 3. A push plate 7 is fixedly connected to the upper end of the moving block 6. Slider 8s are fixedly connected to both ends of the push plate 7, and the slider 8s are slidably connected to the guide rod 5. A cutting groove 9 is formed on the surface of the cutting table 1. A fixing frame 10 is also fixedly connected to its upper end. Two electric push rods 11 are detachably connected to the upper end of the fixing frame 10. A connecting plate 12 is detachably connected to the output end of the electric push rod 11. A first fixing block 13 is fixedly connected to both ends of the connecting plate 12. Rectangular grooves 14 are formed on the inner surfaces of both sides of the fixing frame 10. A sliding block 6 is fixedly connected inside the rectangular groove 14. The first fixing rod 15 and the first fixing block 13 have through holes adapted to the first fixing rod 15. The first fixing rod 15 is fitted through the through holes and slidably connected to the outer surface of the first fixing rod 15. Multiple second fixing blocks 16 are fixedly connected to both sides of the connecting plate 12. A second fixing rod 17 is inserted through the second fixing block 16. A limit block 18 is fixedly connected to the top of the second fixing rod 17 and a pressure plate 19 is fixedly connected to the bottom. A spring 20 is fitted on the outer surface of the second fixing rod 17 between the second fixing block 16 and the pressure plate 19. A knife holder 21 is installed at the bottom of the connecting plate 12. A mounting groove adapted to the cutting blade 22 is opened in the knife holder 21. The back of the cutting blade 22 is embedded in the mounting groove. A threaded hole adapted to the bolt 23 is opened on one side of the knife holder 21 and the threaded hole extends into the mounting groove. The bolt 23 is pressed and fixed to the back of the cutting blade 22 through the threaded hole.

[0015] It should be noted that this utility model is a corrugated paper cutting device for corrugated cardboard box production. In use, the corrugated paper to be cut is first laid flat on the upper surface of the cutting table 1. Then, the servo motor 2 is started, driving the threaded rod 3 to rotate. The threaded rod 3 drives the moving block 6 to slide smoothly along the guide rod 5. The moving block 6 synchronously drives the push plate 7 to move. The push plate 7 pushes the corrugated paper to the preset cutting position directly above the cutting groove 9. Next, two electric push rods 11 are started. The output ends of the electric push rods 11 extend downwards and drive the connecting plate 12 to move downwards. The connecting plate 12 drives the first fixing block 13 to slide along the first fixing rod 15 to ensure the stability of the downward movement of the connecting plate 12. At the same time, the connecting plate 12 drives the second fixing block 16, the second fixing rod 17, and the pressure plate 19 to move downwards synchronously. First, the spring 20 contacts the upper surface of the corrugated paper. As the connecting plate 12 continues to move downward, the spring 20 is compressed and generates elastic pressure. This elastic pressure is transmitted to the corrugated paper through the pressure plate 19, pressing the corrugated paper tightly against the surface of the cutting table 1 to prevent the corrugated paper from shifting during cutting. Then, the connecting plate 12 continues to move downward and drives the knife holder 21 and the cutting knife 22 to move downward. The cutting knife 22 contacts the corrugated paper and completes the cutting operation of the corrugated paper along the cutting groove 9. After the cutting is completed, the output end of the electric push rod 11 is retracted upward. The electric push rod 11 drives the connecting plate 12, the knife holder 21, the cutting knife 22 and the pressure plate 19 to move upward and reset synchronously. The spring 20 returns to its natural state, the pressure plate 19 is separated from the corrugated paper, and finally the cut corrugated paper is removed from the cutting table 1, thus completing the corrugated paper cutting operation.
