Description

Technical Field

[0001] This utility model belongs to the field of cardboard punching technology, and in particular relates to a honeycomb cardboard punching device. Background Technology

[0002] Honeycomb paperboard is a composite board made from recycled paper through a special process to form a honeycomb structure similar to that of a bee. Its core is a core layer composed of dense hexagonal honeycomb-like holes, and the upper and lower surfaces are covered with high-strength surface layers. To facilitate the assembly and splicing of honeycomb paperboard, holes need to be opened during its processing. Currently, existing punching devices either punch holes by directly pressing down on the punch needle, resulting in rigid contact between the punch needle and the cardboard, which accelerates the wear of the punch needle and shortens its service life, or they use a motor to drive the punch needle to rotate and punch holes, which requires continuous power consumption to maintain the operation of the machine, resulting in additional energy consumption and increasing the processing costs of enterprises.

[0003] To address the aforementioned problems, this application proposes a perforation device for honeycomb paperboard. Utility Model Content

[0004] The purpose of this invention is to provide a honeycomb paperboard punching device, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a honeycomb cardboard punching device, including a processing table and a fixed frame fixed on its top surface, and a rotating column that passes through the bottom plate of the lifting box and is rotatably connected to the lifting box. The punching needles below the rotating column are provided with pressure blocks on both sides, and springs are fixed on the top of the pressure blocks. One of the pressure blocks is connected to the rotating column through a transmission mechanism. An electric push rod with an output end fixed to the lifting box is fixed on the top surface of the fixed frame. A connecting block is fixed on the top of the punching needle. A slot is provided on the fixed block on the top surface of the connecting block. An insert is provided in the rotating column for insertion into the slot.

[0006] Furthermore, the lifting box is fixedly provided with fixing plates on both sides, the top of the pressure block is provided with a smooth column that is slidably connected to the fixing plate, and a limiting block fixedly connected to the top of the smooth column is provided above the fixing plate. The top of the spring fixedly connected to the pressure block is fixedly connected to the fixing plate, and the spring is wrapped around the smooth column.

[0007] Furthermore, the transmission mechanism includes a rack fixedly connected to the top of one of the pressure blocks, and the rack meshes with a transmission gear. The lifting box is provided with a bevel gear one fixedly connected to the top of the rotating column. The lifting box is provided with a bevel gear two meshing with bevel gear one, and bevel gear two is fixedly connected to the transmission gear through a connecting shaft. One of the fixed plates is provided with a clearance groove for avoiding the rack.

[0008] Furthermore, the bottom end of the rotating column is provided with a positioning groove that cooperates with the fixed block, and the rotating column is provided with a smooth groove that communicates with the positioning groove, and the insert block is slidably disposed in the positioning groove.

[0009] Furthermore, two movable plates are symmetrically arranged in the cavity of the rotating column, and a bidirectional screw is rotatably installed in the rotating column and threadedly connected to the movable plates. The movable plates are respectively fixed to the insert block through connecting rods.

[0010] Furthermore, a T-shaped guide rail parallel to the moving plate is fixed inside the cavity, and the T-shaped guide rail is slidably connected to the T-shaped grooves opened at the top of the two moving plates.

[0011] Furthermore, the cavity is provided with bevel gear three and bevel gear four that mesh with each other. Bevel gear three is fixedly connected to the outer wall of the bidirectional screw.

[0012] Furthermore, the knob has a cross-shaped groove.

[0013] Furthermore, the processing table has a waste discharge hole, and the axis of the waste discharge hole and the axis of the punching needle are on the same vertical line. A connecting bucket communicating with the waste discharge hole is fixed at the bottom of the processing table, and a collection frame is provided below the connecting bucket.

[0014] This utility model has the following beneficial effects: This invention involves the punching needle continuing to move downwards after the pressure block contacts the cardboard, and the spring applies pressure to the pressure block to press and fix the cardboard. At the same time, the punching needle is driven to rotate through the transmission mechanism to achieve rotary punching and speed up the punching rate.

[0018] 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.

[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] Please see Figure 1 - Figure 6As shown, this utility model is a honeycomb cardboard punching device, including a processing table 1 and a fixed frame 2 fixed on its top surface, and a rotating column 7 that passes through the bottom plate of the lifting box 4 and is rotatably connected to the lifting box 4. The punching needle 9 below the rotating column 7 is provided with pressure blocks 12 on both sides, and a spring is fixed at the top of the pressure block 12. One of the pressure blocks 12 is connected to the rotating column 7 through a transmission mechanism. The top surface of the fixed frame 2 is provided with an electric push rod 3 whose output end is fixed to the lifting box 4. A connecting block 8 is fixed at the top of the punching needle 9. The fixed block 801 on the top surface of the connecting block 8 has a slot 8011. The rotating column 7 is provided with an insert block 15 for insertion into the slot 8011. This embodiment provides a honeycomb cardboard punching device. The electric push rod 3 drives the lifting box 4 to move down, and the rotating column 7 and connecting block 8 drive the punching needle 9 to move down to punch the cardboard. The bottom height of the pressure block 12 is lower than the bottom height of the punching needle 9. After the pressure block 12 contacts the cardboard, the spring is compressed, and the rotating column 7 is rotated through the transmission mechanism. The punching needle 9 is rotated through the connecting block 8 to perform drilling. While increasing the drilling speed, the smoothness of the hole can also be improved. The insert block 15 is inserted into the slot 8011 to fix the fixing block 801. The punching needle 9 is detachably connected to the rotating column 7 through the connecting block 8.

[0021] The lifting box 4 has fixed plates 401 on both sides. The top of the pressure block 12 is provided with a smooth column 1201 that is slidably connected to the fixed plate 401. A limiting block 1202 that is fixed to the top of the smooth column 1201 is provided above the fixed plate 401. The top of the spring that is fixed to the pressure block 12 is fixed to the fixed plate 401, and the spring is wrapped around the smooth column 1201. When the lifting box 4 moves down, the fixed plate 401 drives the pressure block 12 to move down through the spring. The pressure block 12 contacts the cardboard before the punching needle 9 contacts the cardboard. As the lifting box 4 continues to move down, the spring is compressed to generate elastic force and is applied to the cardboard through the pressure block 12 to press and fix the cardboard. The smooth column 1201 restricts the movement direction of the pressure block 12 to prevent the pressure block 12 from deviating.

[0022] The transmission mechanism includes a rack 11 fixedly connected to the top of one of the pressing blocks 12, and the rack 11 meshes with the transmission gear 10. The lifting box 4 is provided with a bevel gear 5 fixedly connected to the top of the rotating column 7. The lifting box 4 is provided with a bevel gear 6 meshing with the bevel gear 5, and the bevel gear 6 is fixedly connected to the transmission gear 10 through a connecting shaft 601. A fixed plate 401 is provided with a clearance groove 4011 for avoiding the rack 11. After the pressing block 12 contacts the cardboard, the lifting box 4 drives the transmission gear 10 to continue to move downward. The transmission gear 10 meshes with the rack 11, driving the bevel gear 6 to rotate, and further driving the rotating column 7 to rotate through the bevel gear 5.

[0023] The rotating column 7 has a positioning groove 703 at its bottom end that mates with the fixing block 801. The rotating column 7 also has a smooth groove 702 that communicates with the positioning groove 703. The insert block 15 is slidably disposed in the positioning groove 703. The positioning groove 703 matches the shape of the fixing block 801. After the fixing block 801 is fully inserted into the positioning groove 703, the slot 8011 is aligned with the positioning groove 703. The fixing between the connecting block 8 and the rotating column 7 is achieved by inserting the insert block 15 into the slot 8011.

[0024] The rotating column 7 has two symmetrically arranged movable plates 14 in the cavity 701. A bidirectional screw 13 is rotatably installed in the rotating column 7 and threadedly connected to the movable plates 14. The movable plates 14 are fixedly connected to the inserts 15 through connecting rods 1401. The rotation of the bidirectional screw 13 drives the two movable plates 14 to move synchronously in opposite directions. Furthermore, the connecting rods 1401 drive the two inserts 15 to move synchronously in opposite directions, so that the inserts 15 are inserted into the slots 8011 or separated from the slots 8011.

[0025] The cavity 701 is fixed with a T-shaped guide rail 704 parallel to the moving plate 14, and the T-shaped guide rail 704 is slidably connected with the T-shaped sliding grooves opened at the top of the two moving plates 14. The T-shaped guide rail 704 and the T-shaped sliding grooves opened on the moving plate 14 cooperate to guide the movement of the moving plate 14 and ensure the stability of the movement of the moving plate 14.

[0026] The cavity 701 contains a bevel gear 3 16 and a bevel gear 4 17 that mesh with each other. The bevel gear 3 16 is fixedly connected to the outer wall of the bidirectional screw 13. The outer wall of the rotating column 7 has a groove, and a knob 18 is fixedly connected to the bevel gear 4 17 through a rotating shaft in the groove. Rotating the knob 18 drives the bevel gear 3 16 to rotate through the bevel gear 4 17, which in turn drives the bidirectional screw 13 to rotate.

[0027] The knob 18 has a cross-shaped groove that can be used with a Phillips screwdriver, allowing the operator to control the rotation of the knob 18 using the Phillips screwdriver.

[0028] The processing table 1 is provided with a waste discharge hole 101, and the axis of the waste discharge hole 101 and the axis of the punching needle 9 are on the same vertical line. The bottom end of the processing table 1 is fixed with a connecting bucket 19 that communicates with the waste discharge hole 101. A collection frame 20 is provided below the connecting bucket 19. The paper scraps generated by punching fall into the waste discharge hole 101 under the action of gravity, and are collected in the collection frame 20 through the connecting bucket 19, realizing the automatic collection of paper scraps and avoiding the accumulation of paper scraps on the processing table 1 from affecting the processing environment.

[0029] Understandably, this invention enables the punch needle 9 to rotate, thereby improving punching efficiency, and also allows for quick replacement of the punch needle 9.

[0030] A specific application of the operation process of this embodiment is as follows: The cardboard is placed on the top surface of the processing table 1. The electric push rod 3 is driven to move the lifting box 4 downward. The pressure block 12 is further moved downward through the fixing plate 401 and the spring. At the same time, the punching needle 9 is moved downward through the rotating column 7. Since the bottom plane of the pressure block 12 is lower than the bottom plane of the punching needle 9, the pressure block 12 will contact the cardboard first. The punching needle 9 continues to move downward. The spring is compressed to press and fix the cardboard. At the same time, the transmission gear 10 meshes with the rack 11 during the downward movement. The transmission gear 10 rotates and drives the bevel gear 6 and bevel gear 5 to rotate. The punching needle 9 is further rotated through the rotating column 7 and the connecting block 8, so that the punching needle 9 can punch holes in the cardboard more easily. The paper scraps generated during the punching process fall into the collection frame 20 through the waste discharge hole 101 and the connecting hopper 19. After the punching is completed, the electric push rod 3 is driven to move the lifting box 4 upward, so that the punching needle 9 and the pressure block 12 are separated from the cardboard. After the pressure block 12 is separated from the cardboard, the spring returns to its original position. The user rotates the knob 18 to drive the bevel gear 17 to rotate, which in turn drives the bidirectional screw 13 to rotate via the bevel gear 16. This causes the two moving plates 14 to move synchronously in opposite directions. Then, the connecting rod 1401 drives the insert block 15 to be inserted into or separated from the slot 8011, thereby fixing or releasing the connecting block 8 and the rotating column 7. This enables a detachable connection between the rotating column 7 and the punch 9, facilitating the replacement of the punch 9.
