Description

Technical Field

[0001] This utility model relates to the field of paper box processing technology, specifically to an indentation device for paper box processing. Background Technology

[0002] A cardboard box is a three-dimensional shape, which is a multi-faceted shape formed by the movement, stacking, folding and surrounding of several surfaces. During the processing of cardboard boxes, a creasing device is required. The creasing device is a key piece of equipment used to form preset creases on the surface of cardboard. Its core function is to cause plastic deformation of cardboard fibers through physical compression, thereby reducing folding resistance and improving forming accuracy.

[0003] A search revealed CN223014027U3, which discloses a high-precision creasing device for paper box processing. This device uses two sets of clamps to hold and stabilize the cardboard placed in the middle, thus preventing it from shifting position during processing and affecting the creases. However, this device requires manual placement or removal of the paper before and after creasing, resulting in low efficiency and making it inconvenient for creasing paper of different sizes. Therefore, we propose a creasing device for paper box processing. Utility Model Content

[0004] The purpose of this invention is to provide an embossing device for paper box processing.

[0005] To address the problems mentioned in the background art, this utility model provides the following technical solution: a creasing device for paper box processing, comprising a base plate, a fixing seat and a side plate fixed to the upper end of the base plate, a control box fixed to one end of the fixing seat, a first bidirectional screw threaded through one end of the fixing seat, a first movable block provided at both ends of the side wall of the first bidirectional screw, a first connecting rod fixed to the upper end of the first movable block, a limit plate fixed to the inner side of the first connecting rod, a conveyor belt provided to the inner side of the fixing seat, a first sliding rod fixed to both sides of one end of the limit plate, and a first sliding rod fixed to both sides of both ends of the fixing seat. A fixed block is fixed to the side plate. An electric telescopic mechanism is fixed to the upper end of the side plate. A lifting plate is fixed to the lower end of the electric telescopic mechanism. A second connecting rod is installed through each of the four corners of the upper end of the lifting plate. An adjusting seat is fixed to the lower end of the second connecting rod. A second bidirectional screw is installed through one side of the adjusting seat. A second moving block is installed on both sides inside the adjusting seat. A first fixing box is fixed to the lower end of each of the second moving blocks. A second sliding rod is fixed to both ends of the adjusting seat. An L-plate is fixed to the side wall of each of the second sliding rods. A second fixing box is fixed to the inner side of each L-plate. A third bidirectional screw is installed through one end of the L-plate.

[0006] Preferably, the first slide rod passes through the fixed block, and the first slide rod is slidably connected to the fixed block.

[0007] Preferably, the second slide rod is slidably connected to the L-plate, and the L-plate is slidably connected to the adjusting seat.

[0008] Preferably, both the first and second fixed boxes are equipped with indentation blocks inside. A spiral column is rotatably provided on one side of both the first and second fixed boxes. A movable plate is provided on one side of the spiral column sidewall. Multiple sets of first springs are provided at the upper end of the adjusting seat. A telescopic cylinder is fixed at the center of the lower end of the adjusting seat. A clamping plate is fixed at the lower end of the telescopic cylinder. A second spring is provided at the upper end of the clamping plate.

[0009] Preferably, the indentation block is slidably connected to both the first fixed box and the second fixed box, the movable plate passes through the indentation block, and the movable plate is slidably connected to the indentation block.

[0010] Preferably, the number of the first springs is eight, and the first springs are located between the adjusting seat and the lifting plate, while the second springs are located between the clamping plate and the adjusting seat.

[0011] Using the above technical solution, by rotating the first bidirectional screw forward, the first bidirectional screw pushes the limiting plates on both sides to move the first sliding rod closer to each other through the first moving block and the first connecting rod, and vice versa. Then, after adjusting the paper to the appropriate position as needed, stop. Then, rotate the second bidirectional screw forward, so that the second bidirectional screw drives the first fixing boxes on both sides to move closer to each other through the second moving block, and the creasing blocks under the first fixing boxes move closer to each other, and vice versa. Then, after adjusting the distance of the creases on both sides of the paper to the appropriate position, stop. The adjustment of the creasing blocks under the second fixing box is the same. The creasing device used for paper box processing can adjust the spacing of the limiting plates to facilitate the limiting of the paper, and can also adjust the spacing of the creasing blocks at the bottom of the second fixing box and the first fixing box to facilitate creases of different sizes.

[0012] Using the above technical solution, the forward rotating spiral column drives the moving plate to one side, causing the moving plate to lose its fixation on the creasing block. The creasing block is then slid out and replaced. After replacement, the spiral column is rotated in reverse to fix the moving plate on the creasing block. When creasing is needed, the electric telescopic mechanism is activated, which pushes the creasing block down through the lifting plate and adjusting seat, allowing the creasing block to creasing. As the creasing block descends, the clamping plate clamps the paper below under the elasticity of the second spring. Furthermore, during creasing, the creasing block pushes the adjusting seat to compress the first spring, preventing the paper from being damaged due to excessive pressure. The creasing device used in paper box processing allows for quick replacement of the creasing block and clamps the paper, facilitating creasing. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Example 1:

[0020] Please see Figure 1-4This utility model provides a technical solution: a creasing device for cardboard box processing, including a base plate 1, a fixing seat 2 and a side plate 11 fixed to the upper end of the base plate 1, a control box 3 fixed to one end of the fixing seat 2, a first bidirectional screw 4 passing through one end of the fixing seat 2, a first moving block 5 provided at both ends of the side wall of the first bidirectional screw 4, a first connecting rod 6 fixed to the upper end of the first moving block 5, a limit plate 7 fixed to the inner side of the first connecting rod 6, a conveyor belt 8 provided to the inner side of the fixing seat 2, a first sliding rod 9 fixed to both sides of one end of the limit plate 7, a fixing block 10 fixed to both sides of both ends of the fixing seat 2, an electric telescopic mechanism 12 fixed to the upper end of the side plate 11, a lifting plate 13 fixed to the lower end of the electric telescopic mechanism 12, and a lifting plate 13. 3. A second connecting rod 14 is provided through each of the four corners of the upper end. An adjusting seat 15 is fixed to the lower end of the second connecting rod 14. A second bidirectional screw 16 is provided through one side of the adjusting seat 15. A second moving block 17 is installed on both sides inside the adjusting seat 15. A first fixing box 18 is fixed to the lower end of each of the second moving blocks 17. A second sliding rod 19 is fixed to both ends of the adjusting seat 15. An L-plate 20 is fixed to the side wall of the second sliding rod 19. A second fixing box 21 is fixed to the inner side of the L-plate 20. A third bidirectional screw 22 is provided through one end of the L-plate 20. A first sliding rod 9 passes through the fixing block 10 and is slidably connected to the fixing block 10. The second sliding rod 19 is slidably connected to the L-plate 20, and the L-plate 20 is slidably connected to the adjusting seat 15.

[0021] Specifically, when paper needs to be placed, the first bidirectional screw 4 is rotated forward, causing the first moving blocks 5 at both ends to move closer together. As the first moving blocks 5 move closer, they also move the limiting plates 7 on both sides together via the first connecting rod 6, reducing the distance between the limiting plates 7. The paper is then adjusted to the appropriate position and stopped. The conveyor belt 8 is then started via the control box 3, and the paper is placed on one side of the conveyor belt 8, causing the conveyor belt 8 to move the paper to the other side. The process stops when the paper is below the adjusting seat 15. The electric telescopic mechanism 12 is then started forward via the control box 3, causing it to push the adjusting seat 15 down via the lifting plate 13, allowing the creasing block 23 to creasing the paper. When the first fixed box 18 and the second... When adjusting the spacing of the creasing blocks 23 below the fixed box 21, the second bidirectional screw 16 is rotated forward, causing the second moving blocks 17 on both sides to move the first fixed boxes 18 closer together, thus reducing the spacing between the first fixed boxes 18. Conversely, rotating the second bidirectional screw 16 forward increases the spacing between the first fixed boxes 18. At the same time, the first fixed boxes 18 will move the creasing blocks 23 below them together. Then, the adjustment is stopped when the distance of the creases on both sides of the paper is adjusted to a suitable position. The adjustment of the spacing between the creasing blocks 23 at the bottom of the second fixed box 21 is similar. The creasing device suitable for paper box processing can adjust the spacing of the limiting plate 7 to facilitate the limiting of the paper, and can also adjust the spacing of the creasing blocks 23 at the bottom of the second fixed box 21 and the first fixed box 18 to facilitate creases of different sizes.

[0022] Example 2:

[0023] Please see Figure 1-4 This utility model provides a technical solution: a creasing device for paper box processing. Crease blocks 23 are installed inside both the first fixed box 18 and the second fixed box 21. A spiral column 24 is rotatably mounted on one side of both the first fixed box 18 and the second fixed box 21. A movable plate 25 is mounted on one side of the spiral column 24. Multiple sets of first springs 26 are mounted on the upper end of the adjusting seat 15. A telescopic cylinder 27 is fixed to the center of the lower end of the adjusting seat 15. A clamping plate 28 is fixed to the lower end of the telescopic cylinder 27. A second spring 29 is mounted on the upper end of the clamping plate 28. The creasing blocks 23 are slidably connected to both the first fixed box 18 and the second fixed box 21. The movable plate 25 passes through the creasing blocks 23 and is slidably connected to the creasing blocks 23. There are eight sets of first springs 26, located between the adjusting seat 15 and the lifting plate 13. The second springs 29 are located between the clamping plate 28 and the adjusting seat 15.

[0024] Specifically, when the indentation block 23 needs to be replaced, the spiral column 24 is rotated forward, causing the moving plate 25 to move to one side, allowing the moving plate 25 to slide out of the indentation block 23. This removes the fixing of the moving plate 25 to the indentation block 23, allowing the indentation block 23 to slide out and be replaced. After replacement, the spiral column 24 is rotated in reverse, causing the moving plate 25 to insert into the indentation block 23, thus fixing the indentation block 23. When indentation is needed, the electric telescopic mechanism 12 is started forward via the control box 3, causing the electric telescopic mechanism 12 to push the lifting plate 13 down, which in turn pushes the adjusting seat 15 below via the second connecting rod 14. The paper begins to descend, and then the creasing block 23 and the moving plate 25 below the adjusting seat 15 descend together. Then the clamping plate 28 contacts the paper surface, and as the adjusting seat 15 continues to descend, the clamping plate 28 squeezes the second spring 29. Then the clamping plate 28 clamps the paper under the elasticity of the second spring 29, so that the creasing block 23 creasing the paper. After the creasing is completed, the electric telescopic machine 12 is reverse-started through the control box 3, so that the electric telescopic machine 12 drives the creasing block 23 back to its original position. The creasing device used for paper box processing can quickly replace the creasing block 23 and can clamp the paper, making it convenient for the creasing block 23 to creasing.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
