Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, specifically a die-cutting machine with a double-sided die-cutting structure. Background Technology

[0002] Paperboard, also known as cardboard, is a thick sheet of paper made from various pulps, composed of interwoven fibers. It is mostly used in the production of cartons and boxes. During processing, paperboard typically requires die-cutting equipment for die-cutting.

[0003] In the prior art, a double-sided die-cutting device for cardboard with authorization announcement number CN216001599U includes a base, with support columns welded to both the left and right sides of the upper surface of the base, a pad welded to the middle between the two support columns, a die-cutting through groove in the middle of the upper surface of the pad, a sliding groove in the right side of the upper surface of the pad, a movable slider that can slide back and forth inside the sliding groove, an air jet pipe that can move back and forth at the front end of the upper surface of the pad, a brush filament embedded at the bottom of the air jet pipe, pressure plates that can slide up and down at both ends between the two support columns, and a die-cutting knife installed on the surface of the two pressure plates facing the pad.

[0004] In the above scheme, two first-step motors are started to rotate two bidirectional lead screws, which causes the die-cutting blades on the two pressure plates to cut the cardboard. However, this structural design has the following disadvantages: on the one hand, dust and impurities are easy to fall onto the surface of the bidirectional lead screws, which will affect the use of the device and reduce its practicality; on the other hand, it increases the number of motors. Utility Model Content

[0005] The purpose of this invention is to provide a die-cutting machine with a double-sided die-cutting structure to solve the problem in the prior art that dust and impurities easily fall onto the surface of the bidirectional lead screw, which affects the performance of the device and reduces its practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a die-cutting machine with a double-sided die-cutting structure, comprising a hollow base, a pad on the top of the hollow base, support plates fixedly connected to both sides of the pad, both support plates fixedly connected to the hollow base, pressure plates on both the upper and lower sides of the pad, and a cutting structure on both pressure plates, two bidirectional screws rotatably connected to the top of the hollow base, a bevel gear fixedly connected to the bottom of each of the two bidirectional screws, a driving structure between the two bevel gears, U-shaped plates threaded to both ends of the outer sides of the two bidirectional screws, four U-shaped plates passing through the top of the hollow base and slidably connected to the hollow base, wherein two U-shaped plates are fixedly connected to one of the pressure plates at both ends, and the other two U-shaped plates are fixedly connected to the bottom of another pressure plate, and a cleaning structure is provided on the top of the pad.

[0007] Preferably, the cutting structure includes multiple T-shaped grooves, all of which are formed on the pressure plate. A T-shaped plate is slidably disposed inside each of the multiple T-shaped grooves. The T-shaped plate is fixed to the pressure plate by bolts. Multiple die-cutting blades are mounted on the T-shaped plate, which allows for the disassembly and replacement of the die-cutting blades.

[0008] Preferably, the pad has multiple die-cutting slots, and the die-cutting blade is positioned corresponding to the die-cutting slots.

[0009] Preferably, the drive structure includes a rotating shaft disposed inside a hollow base. Both ends of the rotating shaft pass through the inner side of the hollow base and are rotatably connected to the hollow base. A forward and reverse motor is fixedly connected to the outer side of the hollow base, and the output end of the forward and reverse motor is fixedly connected to the rotating shaft. Two L-shaped plates are rotatably connected to the outer side of the rotating shaft. The bottom ends of the two L-shaped plates are fixedly connected to the hollow base. The two L-shaped plates are respectively rotatably connected to the outer side of the bottom ends of two bidirectional screws. The arrangement of the two L-shaped plates improves the stability of the rotation of the two bidirectional screws.

[0010] Preferably, the drive structure further includes two bevel gears, both of which are fixedly connected to the outside of the rotating shaft, and are respectively meshed with the outside of the two bevel gears.

[0011] Preferably, the cleaning structure includes an air jet pipe disposed on the top of the pad, a plurality of air jet heads are installed on one side of the air jet pipe, a brush is installed at the bottom of the air jet pipe, and a connecting pipe is fixedly connected to the other side of the air jet pipe.

[0012] Preferably, the cleaning structure further includes a hydraulic cylinder, which is disposed on one side of the jet pipe. A support is fixedly connected to the outside of the hydraulic cylinder, and the support is fixedly connected to one side of the pad. The telescopic end of the hydraulic cylinder is fixedly connected to the jet pipe.

[0013] Preferably, two limiting rods are fixedly connected to the other side of the jet pipe, and a support block is slidably connected to the outside of the limiting rod. The support block is fixedly connected to one side of the pad. By setting the limiting rods and the support block, the movement of the jet pipe can be limited and guided, thereby further improving its movement stability.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application uses two U-shaped plates to drive the pressure plate downwards, and two other U-shaped plates to drive another pressure plate upwards, thereby enabling multiple die-cutting blades to move in opposite directions and simultaneously cut the top and bottom sides of the cardboard. This structural design solves the problems in the prior art where dust and impurities easily fall onto the surface of the bidirectional lead screw, affecting the device's performance, reducing its practicality, and increasing the number of motors.

[0016] 2. This application uses a hydraulic cylinder to activate the extension and retraction end of the hydraulic cylinder, which drives the jet pipe to move. The gas ejected by multiple jet heads can blow away the debris on the pad, while the brush can further clean the surface of the pad. The setting of two limit rods and two support blocks can improve the stability of the jet pipe movement. This structural design avoids the use of a lead screw to drive the jet pipe movement, which would cause debris and other impurities to fall onto the lead screw surface and affect the movement of the jet pipe.

[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] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a die-cutting machine with a double-sided die-cutting structure, including a hollow base 1, a pad 2 on the top of the hollow base 1, support plates 3 fixedly connected to both sides of the pad 2, both support plates 3 being fixedly connected to the hollow base 1, pressure plates 6 on the upper and lower sides of the pad 2, and a cutting structure on each pressure plate 6, the cutting structure including multiple T-slots 7, the multiple T-slots 7 being formed on the pressure plates 6, T-plates 8 being slidably arranged inside the multiple T-slots 7, the T-plates 8 being fixed to the pressure plates 6 by bolts, multiple die-cutting blades 9 being installed on the T-plates 8, and the pad 2 having... Multiple die-cutting slots 200 are provided, with die-cutting blades 9 corresponding to the die-cutting slots 200. Two bidirectional screws 4 are rotatably connected to the top of the hollow base 1. A bevel gear 10 is fixedly connected to the bottom of each of the two bidirectional screws 4. A drive structure is provided between the two bevel gears 10. U-shaped plates 5 are threaded to both ends of the two bidirectional screws 4. All four U-shaped plates 5 pass through the top of the hollow base 1 and are slidably connected to the hollow base 1. Two of the U-shaped plates 5 are fixedly connected to one of the pressure plates 6 at both ends, and the other two U-shaped plates 5 are fixedly connected to the bottom of the other pressure plate 6. A cleaning structure is provided on the top of the pad 2.

[0024] The drive structure includes a rotating shaft 12, which is located inside the hollow base 1. Both ends of the rotating shaft 12 pass through the inner side of the hollow base 1 and are rotatably connected to the hollow base 1. A forward and reverse motor 13 is fixedly connected to the outer side of the hollow base 1. The output end of the forward and reverse motor 13 is fixedly connected to the rotating shaft 12. Two L-shaped plates 400 are rotatably connected to the outer side of the rotating shaft 12. The bottom ends of the two L-shaped plates 400 are fixedly connected to the hollow base 1. The two L-shaped plates 400 are rotatably connected to the outer side of the bottom ends of two bidirectional screws 4, respectively. The drive structure also includes two bevel gears 11, which are fixedly connected to the outer side of the rotating shaft 12. The two bevel gears 11 are meshed with the outer side of two bevel gears 10, respectively.

[0025] Specifically, starting the forward and reverse motor 13 (the specific model of the forward and reverse motor 13 is not limited, but depends on the compatible equipment) causes the output end of the forward and reverse motor 13 to drive the rotating shaft 12 to rotate on the hollow base 1. When the rotating shaft 12 rotates, it will drive the two bevel gears 11 to rotate. Since the two bevel gears 11 mesh with the two bevel gears 10 respectively, the two bevel gears 10 will rotate accordingly. The rotation of the bevel gears 10 will drive the two bidirectional screws 4 to rotate. The bidirectional screws 4 are threadedly connected to the two U-shaped plates 5. Thus, two of the U-shaped plates 5 drive the pressure plate 6 to move downward, and the other two U-shaped plates 5 drive the other pressure plate 6 to move upward. This enables multiple die-cutting blades 9 to move in opposite directions, achieving simultaneous cutting of the top and bottom sides of the cardboard. This structural design solves the problems in the existing technology where dust and impurities easily fall onto the surface of the bidirectional screws, affecting the use effect of the device, reducing the practicality of the device, and increasing the number of motors.

[0026] In addition, by removing the bolts on the pressure plate 6, the T-shaped plate 8 can be released from its position, and the T-shaped plate 8 can be pulled out from inside the T-groove 7, thus enabling the replacement of the die-cutting blade 9.

[0027] Example: Figure 1 and Figure 4 As shown, the cleaning structure includes a jet pipe 14, which is located on the top of the pad 2. Multiple jet heads 15 are installed on one side of the jet pipe 14, and a brush 16 is installed at the bottom of the jet pipe 14. A connecting pipe 17 is fixedly connected to the other side of the jet pipe 14. The cleaning structure also includes a hydraulic cylinder 18, which is located on one side of the jet pipe 14. A support 19 is fixedly connected to the outside of the hydraulic cylinder 18. The support 19 is fixedly connected to one side of the pad 2. The telescopic end of the hydraulic cylinder 18 is fixedly connected to the jet pipe 14. Two limiting rods 20 are fixedly connected to the other side of the jet pipe 14. A support block 21 is slidably connected to the outside of the limiting rods 20. The support block 21 is fixedly connected to one side of the pad 2.

[0028] Specifically, the connecting pipe 17 is connected to an external device such as an air pump. After the gas enters the jet pipe 14, it can be sprayed out through multiple jet nozzles 15. The hydraulic cylinder 18 is activated, and the extension end of the hydraulic cylinder 18 drives the jet pipe 14 to move. The gas sprayed out through the multiple jet nozzles 15 can blow away the debris on the pad 2, while the brush 16 can further clean the surface of the pad 2. The stability of the movement of the jet pipe 14 can be improved by setting two limit rods 20 and two support blocks 21. This structural design avoids the use of a lead screw to drive the movement of the jet pipe 14, which would cause debris and other impurities to fall onto the lead screw surface and affect the movement of the jet pipe 14.
