DETAILED DESCRIPTION
[0018] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).
[0019] Example: A punching device for cardboard packaging, such as Figs. 1-3 As shown, the device includes a base 1, a mounting plate 2, a limiting plate 3, a first electric push rod 4, a push plate 5, a fixing plate 6, a second electric push rod 7, a punched part 8, a return spring 9, a pressure plate 10, a cutting plate 101, and a top plate 14. The bottom of the base 1 is connected to four adjustable support pads to maintain the stability of the device. The mounting plate 2 is welded onto the base 1. A limiting plate 3 is welded to the left and right sides of the rear end of the top surface of the mounting plate 2. The first electric push rod 4 is mounted on the front side of the mounting plate 2. The telescopic rod of the first electric push rod 4 faces backward and is fixedly connected to the push plate 5. The top plate 14 is located at the front end of the top surface of the mounting plate 2. When the operator places the cardboard box upside down on the mounting plate 2, the front end of the cardboard box is positioned between the top plate 14 and the push plate 5, with the left and right sides in contact with the limiting plates 3. Activating the first electric push rod 4 causes its telescopic rod to push the push plate 5 backward, clamping the front end of the cardboard box between the push plate 5 and the top plate 14. The top plate 14 has a large area and, together with the limiting plate 3, restricts the left and right positions of the cardboard boxes, ensuring that each cardboard box is in the same position after being fixed, providing precise positioning for subsequent punching. The mounting plate 2 is fixedly connected to the left and right sides of the mounting plate 6. The fixing plate 6 is equipped with a second electric push rod 7. The telescopic rods of the two second electric push rods 7 are facing each other, and the telescopic rods are fixedly connected to the punching parts 8. The punching parts 8 are slidably connected to the pressure plate 10. The punching parts 8 are fitted with a return spring 9. One end of the return spring 9 is welded to the punching parts 8, and the other end is welded to the pressure plate 10. Two cutting plates 101 are welded to the middle of the mounting plate 2. The pressure plate 10 and the cutting plates 101 are pressed together. The punching parts 8 pass through the cutting plates 101. A waste outlet 11 is opened between the base 1 and the mounting plate 2. The waste outlet 11 is located below the opposite sides of the two punching parts 101. After the cardboard box is fixed, the second electric push rod 7 is activated, and its telescopic rod pushes the punching parts 8 to move towards the cutting plates 101. The pressure plate 10 first contacts the cardboard box and, together with the cutting plate 101, squeezes the cardboard box, keeping the punched area taut. The second electric push rod 7 continues to push the punching component 8, compressing the return spring 9. The punching component 8 passes through the pressure plate 10 and the cutting plate 101, punching the cardboard box to ensure a smooth, burr-free cut. After punching, the second electric push rod 7 pulls the punching component 8 back to its original position, the return spring 9 rebounds, the pressure plate 10 separates from the cutting plate 101, and the cardboard box remains flat with a burr-free cut.
[0020] like Fig. 1 and Fig. 3As shown, it also includes a sliding plate 13 and a limiting rod 15. Eight limiting holes 12 are opened in the middle of the mounting plate 2. The limiting rod 15 is in interference fit with the limiting hole 12, which ensures the position of the sliding plate 13 is fixed. The moving distance of the push plate 5 is automatically adjusted according to the length of the paper box, which ensures the clamping effect. The sliding plate 13 is slidingly connected in the middle of the mounting plate 2. The top plate 14 is welded on the sliding plate 13. A through hole is opened on the sliding plate 13. When the position of the top plate 14 needs to be adjusted to adapt to paper boxes of different lengths, the staff pulls out the limiting rod 15, slides the sliding plate 13 to the target position, and makes the top plate 14 match the length of the paper box. Then the limiting rod 15 is inserted into the through hole of the sliding plate 13 and clamped into the corresponding limiting hole 12. The limiting rod 15 is in interference fit with the limiting hole 12, which ensures the position of the sliding plate 13 is fixed. The moving distance of the push plate 5 is automatically adjusted according to the length of the paper box, which ensures the clamping effect.
[0021] As shown in Figs. 1-3 It also includes a collection box 16. The collection box 16 is slidingly connected to the bottom of the base 1. The collection box 16 is located below the waste port 11. The paper pieces generated during the punching process fall into the waste port 11 between the base 1 and the mounting plate 2 through the cutout plate 101, and finally fall into the collection box 16 located below the waste port 11. The staff regularly pulls out the collection box 16 from the bottom of the base 1 to clean the paper waste and keep the equipment clean.
[0022] As shown in Fig. 1 It also includes a sponge pad 17. The opposite side of the push plate 5 and the top plate 14 is connected with a sponge pad 17. When the first electric push rod 4 pushes the push plate 5 to clamp the paper box, the sponge pad 17 plays a buffering and protection role, avoiding damage to the surface of the paper box due to excessive clamping force.
[0023] As shown in Fig. 1 It also includes a roller 18. A plurality of rollers 18 are rotatably connected to the left and right ends of the mounting plate 2. When the push plate 5 pushes the paper box, the roller 18 rotates, reducing the friction between the paper box and the mounting plate 2, making the paper box move more smoothly, and avoiding scratching the surface of the paper box.
[0024] As shown in Fig. 1 It also includes an identification card 19. Eight identification cards 19 are connected in the middle of the mounting plate 2. The positions of the identification cards 19 correspond to the positions of the limiting holes 12. The staff can directly select the corresponding limiting hole 12 through the identification card 19 according to the length of the paper box, quickly adjust the positions of the sliding plate 13 and the top plate 14, optimize the operation process, and improve the work efficiency.
[0025] The worker turns the paper box upside down on the installation plate 2, the front end of the paper box is clamped by the top plate 14 and the push plate 5, and the left and right sides are positioned by the limiting plate 3. The first electric push rod 4 is started to push the push plate 5 to fix the paper box, and then the second electric push rod 7 is started to push the punching element 8 to punch. The pressing plate 10 and the cutting plate 101 extrude the paper box, so that the punching area is taut, and burrs are avoided. After punching, the punching element 8 is reset, and the worker takes out the paper box.
[0026] For paper boxes of different lengths, the position of the top plate 14 is adjusted by sliding the sliding plate 13, and is fixed by the limiting rod 15. The friction when the paper box moves is reduced by the roller 18, and the identification card 19 helps to quickly select the limiting hole 12. The waste generated by punching falls into the collection box 16 through the waste port 11, and can be cleaned regularly.
[0027] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
