Description

Technical Field

[0001] This utility model belongs to the field of packaging box die-cutting technology, specifically a packaging box die-cutting device. Background Technology

[0002] Packaging box die-cutting equipment is mainly used for die-cutting operations of paper boxes and other products in the paper packaging industry. It is an important piece of equipment for processing and forming packaging boxes. It uses a die-cutting knife to apply a certain pressure to cut the cardboard into a certain shape.

[0003] Existing die-cutting equipment consists of components such as a die-cutting blade, a cylinder, a pressure valve, a placement rack, and a conveyor belt. The packaging box to be die-cut is placed on the placement rack, and then the cylinder drives the die-cutting mold to move toward the packaging box, thereby performing the die-cutting process on the packaging box.

[0004] Existing devices place packaging boxes directly on the conveyor belt surface and transport them to the die-cutting blade. During the transport process, the sides of the packaging box are not fixed, which can easily cause the packaging box to move, resulting in poor quality of the die-cut packaging box. Therefore, a packaging box die-cutting device is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a packaging box die-cutting device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a packaging box die-cutting device, including: a support plate, a processing table fixedly connected to one side of the support plate, a first support frame fixedly connected to the upper surface of the support plate, a first drive motor fixedly connected to one side of the first support frame, a threaded rod fixedly connected to the output end of the first drive motor, both ends of the threaded rod being rotatably connected to the inside of the first support frame, two sets of adjusting blocks threadedly connected to the threaded rod, the two sets of adjusting blocks being slidably connected to the outside of the first support frame, a connecting rod fixedly connected to the lower surface of the two sets of adjusting blocks, a connecting frame fixedly connected to one end of the connecting rod, a positioning rod fixedly connected to the inner side of the connecting frame, a rotating rod rotatably connected to the positioning rod, a limiting block fixedly connected to the bottom of the connecting frame, a limiting groove fixedly connected to the upper surface of the support plate, the limiting block being slidably connected in the limiting groove, the limiting block being located in the limiting groove and cooperating with the connecting rod, thereby improving the stability of the connecting frame.

[0007] Preferably, a second drive motor is fixedly connected to one side of the support plate, and a first drive shaft is fixedly connected to the output end of the second drive motor. The two ends of the first drive shaft are rotatably connected to the inside of the support plate. A conveyor belt is driven to the surface of the first drive shaft, and a second drive shaft is driven to the inner wall of the conveyor belt. When the second drive motor is started, the first drive shaft is driven to rotate, which in turn drives the conveyor belt to rotate, thereby driving the second drive shaft to rotate, so that the packaging box to be die-cut can be transported to the bottom of the die-cutting knife.

[0008] Preferably, both ends of the second drive shaft are rotatably connected to the inside of the support plate. A second support frame is fixedly connected to the upper surface of the processing table. A press is fixedly connected to the upper surface of the second support frame. A connecting plate is fixedly connected to the telescopic end of the press. A die-cutting blade is provided on the lower surface of the connecting plate. When the press is started, the connecting plate and the die-cutting blade move downward, thereby performing a die-cutting operation on the packaging box.

[0009] Preferably, the processing table is provided with a suction hole, and a large-pore filter screen is provided on the upper surface of the processing table. The large-pore filter screen is located above the suction hole, and a suction pipe is fixedly connected to the lower surface of the processing table. The debris generated during die cutting can fall into the suction hole through the large-pore filter screen, thereby reducing the debris on the surface of the large-pore filter screen.

[0010] Preferably, one end of the suction pipe is fixedly connected to the bottom of the suction hole, and a collection box is fixedly connected to the processing table. The collection box is to which one end of the suction pipe is fixedly connected. The debris generated during die cutting is sucked into the collection box through the large-pore filter and the suction hole under the action of the fan, thereby avoiding excessive debris accumulation on the processing table.

[0011] Preferably, a fan is provided on one side of the collection box, a baffle is hinged to one side of the processing table, a handle is fixedly connected to one side of the baffle, and an elastic piece is fixedly connected to one side of the baffle. One end of the elastic piece is fixedly connected to one side of the processing table. When the handle is released, the pressure on the elastic piece decreases, which drives the baffle to return to its original position, thereby blocking the next packaging box.

[0012] The advantages of this invention are: it limits the range of movement of the packaging box on both sides during transmission, thus preventing displacement of the packaging box during transmission. The first drive motor drives the threaded rod to rotate. Because the internal threads of the two sets of adjusting blocks are opposite, the distance between the two sets of adjusting blocks can be reduced or increased when the threaded rod rotates. The connecting rod drives the connecting frame, positioning rod and rotating rod to move synchronously, so that the two sides of the packaging box are in contact with the surfaces of the two sets of rotating rods, thereby limiting the position of the two sides of the packaging box. The friction generated when the packaging box passes over the surfaces of multiple sets of rotating rods drives the multiple sets of rotating rods to rotate, avoiding affecting the transmission speed of the packaging box, and thus improving the die-cutting quality and efficiency of the packaging box.

[0013] This invention ensures that the debris generated during the die-cutting of packaging boxes falls above the large-pore filter screen. Subsequently, the fan operates, and through the collection box, suction hole, and suction pipe, the air between the large-pore filter screen and the packaging box is drawn into the collection box. Under the action of the fan, the debris generated during die-cutting is drawn into the collection box through the large-pore filter screen and suction hole, thereby avoiding the accumulation of too much debris on the processing table, which would affect the efficiency of subsequent processing.

[0021] 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 scope of protection of the present utility model.

[0022] Please see Figure 1-5 As shown, a packaging box die-cutting device includes: a support plate 1, a processing table 2 fixedly connected to one side of the support plate 1, a first support frame 3 fixedly connected to the upper surface of the support plate 1, a first drive motor 4 fixedly connected to one side of the first support frame 3, a threaded rod 5 fixedly connected to the output end of the first drive motor 4, both ends of the threaded rod 5 being rotatably connected inside the first support frame 3, two sets of adjusting blocks 6 threadedly connected to the threaded rod 5, the two sets of adjusting blocks 6 being slidably connected to the outside of the first support frame 3, a connecting rod 7 fixedly connected to the lower surface of the two sets of adjusting blocks 6, and a connecting frame 8 fixedly connected to one end of the connecting rod 7. A positioning rod 9 is fixedly connected to the inner side of the connecting frame 8, and a rotating rod 10 is rotatably connected to the positioning rod 9. A limiting block 11 is fixedly connected to the bottom of the connecting frame 8, and a limiting groove 12 is fixedly connected to the upper surface of the support plate 1. The limiting block 11 is slidably connected in the limiting groove 12. A second drive motor 13 is fixedly connected to one side of the support plate 1. A first drive shaft 14 is fixedly connected to the output end of the second drive motor 13. Both ends of the first drive shaft 14 are rotatably connected to the inside of the support plate 1. A transmission belt 15 is driven to the surface of the first drive shaft 14, and a second drive shaft 16 is driven to the inner wall of the transmission belt 15.

[0023] When die-cutting the packaging box, the movement range of the packaging box on both sides during transport is limited to prevent displacement of the packaging box during die-cutting and transport. In actual use, the packaging box is placed on the surface of the conveyor belt 15, and the first drive motor 4 is started, driving the threaded rod 5 to rotate. Because the internal threads of the two sets of adjusting blocks 6 are opposite, the rotation of the threaded rod 5 can reduce or increase the distance between the two sets of adjusting blocks 6. Through the connecting rod 7, the connecting frame 8, positioning rod 9 and rotating rod 10 move synchronously, so that the two sides of the packaging box are in contact with the surfaces of the two sets of rotating rods 10, thereby limiting the position of the two sides of the packaging box. Then, the second drive motor 13 is started, which drives the first drive shaft 14 to rotate, thereby driving the conveyor belt 15 to drive the second drive shaft 16 to rotate. This allows the packaging box to be die-cut to be transported to the area below the die-cutting blade 20. When the packaging box moves, it passes over the surface of multiple sets of rotating rods 10. The friction generated causes the multiple sets of rotating rods 10 to rotate on the positioning rod 9. This restricts the position of the packaging box on both sides, thus avoiding affecting the conveying speed of the packaging box. In addition, the left and right positions of the packaging box can be fixed during the conveying process. Furthermore, the connecting frame 8 extends to the processing table 2, which can be used to fix the packaging box during die-cutting.

[0024] Please see Figure 1-5As shown, both ends of the second drive shaft 16 are rotatably connected to the inside of the support plate 1. A second support frame 17 is fixedly connected to the upper surface of the processing table 2. A press 18 is fixedly connected to the upper surface of the second support frame 17. A connecting plate 19 is fixedly connected to the telescopic end of the press 18. A die-cutting blade 20 is provided on the lower surface of the connecting plate 19. A suction hole 21 is provided on the processing table 2. A large-pore filter screen 22 is provided on the upper surface of the processing table 2. The large-pore filter screen 22 is located above the suction hole 21. The lower surface of the processing table 2... A suction pipe 23 is fixedly connected to the surface, and one end of the suction pipe 23 is fixedly connected to the bottom of the suction hole 21. A collection box 24 is fixedly connected to the processing table 2. One end of the suction pipe 23 is fixedly connected to the collection box 24. A fan 25 is provided on one side of the collection box 24. A baffle 26 is hinged to one side of the processing table 2. A handle 27 is fixedly connected to one side of the baffle 26. An elastic piece 28 is fixedly connected to one side of the baffle 26. One end of the elastic piece 28 is fixedly connected to one side of the processing table 2.

[0025] The packaging box is conveyed to the surface of the large-pore filter screen 22 via the conveyor belt 15, and simultaneously positioned below the die-cutting blade 20. The blower 25 is activated, drawing air from between the large-pore filter screen 22 and the packaging box through the collection box 24, suction hole 21, and suction pipe 23. This, in conjunction with the connecting frame 8, increases the fixing strength of the packaging box. At the same time, the baffle 26 restricts the position of the packaging box on the other side, preventing it from falling off the other side of the processing table 2. The press 18 is activated, causing the connecting plate 19 and the die-cutting blade 20 to move downwards, thereby performing the die-cutting operation on the packaging box. During die-cutting, the debris generated is drawn into the collection box 24 through the large-pore filter 22 and the suction hole 21 by the blower 25, thus avoiding excessive debris accumulation on the processing table 2 and thus avoiding affecting the subsequent die-cutting quality. After die-cutting, pull the handle 27 to rotate the baffle 26 and squeeze the elastic sheet 28, so that the baffle 26 is in a horizontal state, and the die-cut packaging box can be taken out. Release the handle 27, the pressure on the elastic sheet 28 decreases, and the baffle 26 returns to its original position, thus blocking the next packaging box.

[0026] Working principle: The packaging box is placed on the surface of the conveyor belt 15. The first drive motor 4 is started, driving the threaded rod 5 to rotate, narrowing or widening the distance between the two sets of adjusting blocks 6. This causes the connecting rod 7 to drive the connecting frame 8, positioning rod 9, and rotating rod 10 to move synchronously, so that the two sides of the packaging box are in contact with the surfaces of the two sets of rotating rods 10, thus restricting the position of the two sides of the packaging box. The second drive motor 13 is started, driving the first transmission shaft 14 to rotate, which in turn drives the conveyor belt 15 to rotate, thereby driving the second transmission shaft 16 to rotate. This allows the packaging box to be die-cut to be conveyed to the surface of the large-pore filter screen 22 and below the die-cutting blade 20. The fan 25 is then started to... Air is drawn between the large-pore filter 22 and the packaging box. The press 18 is started, which moves the connecting plate 19 and the die-cutting blade 20 downward to perform die-cutting on the packaging box. Under the action of the fan 25, the debris generated during die-cutting is sucked into the collection box 24 through the large-pore filter 22 and the suction hole 21. After die-cutting, the handle 27 is pulled to rotate the baffle 26, which in turn squeezes the elastic sheet 28, so that the baffle 26 is in a horizontal state, and the die-cut packaging box can be taken out. When the handle 27 is released, the pressure on the elastic sheet 28 decreases, which causes the baffle 26 to return to its original position, thereby blocking the next packaging box.
