[0029] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0030] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the terminology.

[0031] Reference Figures 1-6 As shown, a creasing device for packaging box processing includes: a bracket 105 fixedly mounted on a base 100; a mounting plate 108 movably mounted on the bracket 105 via a hydraulic rod 107; two sets of opposing creasing plates 106 with adjustable spacing provided within the mounting plate 108 via an adjusting mechanism 400; a horizontal clearance groove 104 formed on the base 100; and clamping mechanisms 200 for limiting cardboard of different sizes fixedly mounted on both sides of the clearance groove 104 on the base 100.

[0032] The clamping mechanism 200 includes: two clamping members arranged opposite each other with adjustable spacing, and a limiting component 300 provided on the clamping members near the clearance groove 104 for limiting the upper and lower surfaces of the cardboard to prevent it from warping when indented.

[0033] In use, the cardboard to be creasing is placed on the base 100. The spacing of the clamping members in the clamping mechanism 200 is adjusted to ensure that the clamping members fit tightly against both sides of the cardboard, thus limiting the horizontal movement of the cardboard and preventing it from moving left or right during creasing. The limiting component 300 limits the top and bottom surfaces of the cardboard to ensure that it does not lift up during creasing, further fixing the position of the cardboard and ensuring the stability of the creasing process. According to the width of the cardboard and the desired creasing position, the spacing of the two sets of creasing plates 106 in the mounting plate 108 is adjusted by the adjusting mechanism 400 to ensure that the creasing plates 106 precisely correspond to the desired creasing position on the cardboard. The hydraulic rod 107 is activated, pushing the mounting plate 108 downward. The mounting plate 108 then moves the creasing plates 106 downward. When the creasing plates 106 contact the cardboard, pressure is applied to press the desired mark onto the cardboard. During the creasing process, the cardboard remains stable due to the limiting effect of the clamping mechanism 200, ensuring the accuracy and consistency of the creasing. The clamping mechanism 200, with its pair of opposing clamping members and adjustable spacing, allows for flexible spacing adjustments to accommodate different sizes of cardboard, effectively limiting the movement of various cardboard specifications. Simultaneously, the adjustment mechanism 400 adjusts the spacing of the creasing plates 106 to meet the needs of different cardboard sizes and creasing positions, significantly improving the versatility and applicability of the creasing device. This reduces the need for equipment replacement or complex adjustments due to changes in cardboard size, lowering production costs. The limiting component 300, located near the clearance groove 104 on the clamping member, limits the top and bottom surfaces of the cardboard during creasing, effectively preventing the cardboard from warping under creasing force. This not only ensures the stability of the creasing process but also improves creasing quality, preventing incomplete or deviated creasing due to cardboard warping, thus increasing the product yield.

[0034] Reference Figures 2-4 As shown, the clamping component includes: a slide bar 202, a spring 204, and a clamping plate 205; wherein,

[0035] A fixing plate 201 is fixedly provided on the base 100. A slide rod 202 slides through the fixing plate 201. A clamping plate 205 is fixedly provided at the top of the slide rod 202. A spring 204 is sleeved on the slide rod 202, with its two ends respectively abutting against the side wall of the fixing plate 201 and the side wall of the clamping plate 205. A limiting rod 203 is fixedly provided on the clamping plate 205, which is parallel to the slide rod 202 and slides through the fixing plate 201. A limiting component 300 is provided on the clamping plate 205 near the clearance groove 104.

[0036] In the above scheme, as the cardboard is placed, the two sides of the cardboard push the clamping plate 205 towards the center of the cardboard. During this process, the slide bar 202 slides within the fixed plate 201, and the spring 204 is compressed. Since the limiting rod 203 is parallel to the slide bar 202 and slides through the fixed plate 201, it can ensure the stability of the clamping plate 205 during movement and prevent the clamping plate 205 from tilting or wobbling. When the clamping plate 205 is tightly attached to both sides of the cardboard, the elasticity of the spring 204 provides a continuous clamping force to the clamping plate 205, ensuring that the cardboard is stably limited in the horizontal direction and preventing lateral movement during the creasing process. At the same time, the limiting component 300 limits the top and bottom surfaces of the cardboard, completing the all-round fixation of the cardboard.

[0037] Reference Figures 3-4 As shown, the clamping plate 205 is provided with multiple sets of guide rollers 206 that rotatably contact the sides of the cardboard.

[0038] During the process of placing the cardboard onto the base 100, the side of the cardboard contacts the guide roller 206 rotatably mounted inside the clamping plate 205. As the cardboard is pushed, the guide roller 206 begins to rotate, reducing the friction between the cardboard and the clamping plate 205, allowing the cardboard to enter the appropriate indentation position more smoothly. In this process, the rotation direction of the guide roller 206 is adapted to the movement direction of the cardboard, ensuring that the cardboard is stably placed in the predetermined position.

[0039] Reference Figures 4-5 As shown, the limiting component 300 includes: a first connecting rod 301 and a spring post 303; the first connecting rod 301 is hinged on the clamping plate 205 near the clearance groove 104, and the spring post 303 is fixed on the clamping plate 205, and the movable end of the spring post 303 is hinged to the first connecting rod 301.

[0040] In the above scheme, when the cardboard to be creasing is placed on the base 100 and pushed between the clamping plates 205, the edge of the cardboard gradually approaches the first connecting rod 301. As the cardboard is further pushed forward, it pushes the first connecting rod 301 to rotate around its hinge point with the clamping plate 205. During this process, the movable end of the spring post 303 moves with the rotation of the first connecting rod 301, and the spring post 303 is compressed or stretched. The elastic force generated by the spring post 303 provides a reverse force to the first connecting rod 301, so that the first connecting rod 301 always remains in contact with the surface of the cardboard, playing a preliminary limiting role on the upper surface of the cardboard and preventing the cardboard from warping during placement. When the creasing plate 106 creasing the cardboard, the cardboard is subjected to downward pressure. At this time, under the elastic force of the spring post 303, the first connecting rod 301 continues to be tightly attached to the upper surface of the cardboard. Even if the cardboard has a slight tendency to move up and down under the pressure of the indentation force, the elasticity of the spring column 303 can adaptively adjust the position of the first connecting rod 301, always maintaining effective limitation on the upper surface of the cardboard. Together with the limitation of the side of the cardboard by the clamping plate 205 and the possible support for the lower surface of the cardboard, it ensures the stability of the cardboard during the indentation process, prevents the cardboard from warping or causing large displacement, and ensures the accuracy of the indentation.

[0041] Reference Figure 5 As shown, a pressure roller 302 is rotatably mounted on the first connecting rod 301, with the rotation direction being consistent with the forward direction of the paperboard and in contact with the upper surface of the paperboard.

[0042] In the above scheme, when the cardboard is placed on the base 100 and pushed between the clamping plates 205, the upper surface of the cardboard contacts the pressure roller 302 rotatably mounted on the first connecting rod 301. As the cardboard is pushed, the pressure roller 302 begins to rotate, and its rotation direction is consistent with the forward direction of the cardboard. The rotation of the pressure roller 302 greatly reduces the friction between the cardboard and the first connecting rod 301, allowing the cardboard to be placed more smoothly into the appropriate indentation position.

[0043] Reference Figure 6 As shown, the adjustment mechanism 400 includes: a fixed rod 405 and a driving component; a horizontally arranged limiting groove 404 is provided on the mounting plate 108, and two sets of fixed rods 405 with adjustable spacing are slidably arranged in the limiting groove 404; the indentation plate 106 is fixedly arranged on the fixed rods 405; and a driving component for adjusting the spacing between the two sets of fixed rods 405 is also provided in the mounting plate 108.

[0044] In the above scheme, the driving mechanism is activated according to the size of the cardboard to be creasing and the desired creasing position. The driving mechanism starts working, pushing two sets of fixed rods 405 to slide relative to each other within the limiting groove 404. As the fixed rods 405 slide, the creasing plates 106 fixed to them also move, thereby changing the distance between the two sets of creasing plates 106. When the creasing plates 106 move to precisely correspond to the desired creasing position on the cardboard, the driving mechanism stops, completing the adjustment of the distance between the creasing plates 106. After the distance adjustment is complete, the hydraulic rod 107 pushes the mounting plate 108 down, causing the creasing plates 106 to contact the cardboard and perform the creasing operation. During the creasing process, the fixed rods 405 remain stable within the limiting groove 404, ensuring that the position of the creasing plates 106 remains unchanged to guarantee the accuracy of the creasing.

[0045] Reference Figure 6 As shown, the driving component includes: a servo motor 401, a rotating rod 402, and a second connecting rod 403; wherein,

[0046] A servo motor 401 is fixedly mounted on the mounting plate 108. The output shaft of the servo motor 401 is vertically downward and a rotating rod 402 is fixedly mounted at its top. The two ends of the rotating rod 402 are respectively hinged to a second connecting rod 403. One end of each of the two sets of second connecting rods 403 is respectively hinged to two sets of fixed rods 405.

[0047] In the above scheme, when it is necessary to adjust the spacing of the indentation plates 106, the servo motor 401 is started. The output shaft of the servo motor 401 begins to rotate, driving the rotating rod 402 to rotate synchronously. Since the second connecting rods 403 at both ends of the rotating rod 402 are hinged to the fixed rods 405 respectively, the rotation of the rotating rod 402 will change the angle between the second connecting rods 403 and the rotating rod 402. As the rotating rod 402 rotates, the position of the second connecting rods 403 changes, and the force is transmitted through the hinge point, causing the two sets of fixed rods 405 to slide relative to each other in the limiting groove 404. Because the second connecting rods 403 at both ends of the rotating rod 402 move synchronously, the two sets of fixed rods 405 will move relative to each other or away from each other, thereby driving the indentation plates 106 fixed on them to adjust the spacing.

[0048] Reference Figures 1-2 As shown, the indentation device further includes a first conveyor belt 101 and a second transmission belt 103 located on both sides of the clearance groove 104 and disposed in the base 100 for conveying cardboard. The first conveyor belt 101 and the second transmission belt 103 are both driven by a drive motor 102.

[0049] In the above scheme, the arrangement of the first conveyor belt 101 and the second transmission belt 103 enables automatic conveying of cardboard, reducing the time and labor intensity of manual handling and placement of cardboard. Controlled by the drive motor 102, the cardboard can be quickly and accurately conveyed to the predetermined position, improving the continuity and production efficiency of the creasing operation, making it suitable for large-scale packaging box processing and production.

[0050] In summary, the packaging box creasing device provided by this utility model involves placing the cardboard to be creasing onto the first conveyor belt 101 and starting the drive motor 102. The drive motor 102 drives the first conveyor belt 101 to rotate, conveying the cardboard towards the clearance groove 104. When the front end of the cardboard approaches the clearance groove 104, the second transmission belt 103 starts synchronously under the action of the drive motor 102, working in coordination with the first conveyor belt 101 to accurately convey the cardboard to a predetermined position above the clearance groove 104. As the cardboard is conveyed into place, the two sides of the cardboard push the clamping plate 205 to move inward. The slide rod 202 slides within the fixed plate 201, and the spring 204 is compressed. The resulting elastic force causes the clamping plate 205 to tightly adhere to the side of the cardboard, completing the horizontal limitation of the cardboard. During this process, the limiting rod 203 ensures that the clamping plate 205 moves smoothly and avoids tilting. At the same time, the limiting component 300 plays its role. The edge of the cardboard pushes the first connecting rod 301 to rotate around its hinge point with the clamping plate 205. The movable end of the spring column 303 moves accordingly, compressing or stretching the spring column 303. Its elasticity ensures that the first connecting rod 301 remains in contact with the upper surface of the cardboard, initially limiting the cardboard's upper surface from warping. If the cardboard is thicker, the rotation amplitude of the first connecting rod 301 increases, and the spring column 303 provides a greater counterforce to maintain the limit. If a pressure roller 302 is provided on the first connecting rod 301, during cardboard placement and subsequent creasing, the pressure roller 302 contacts the upper surface of the cardboard and rotates with the cardboard's movement or due to minor displacement caused by the cardboard's stress, reducing friction between the cardboard and the first connecting rod 301, further ensuring the cardboard's stable position, while also dispersing the creasing force, making the cardboard more evenly stressed. Based on the cardboard's size and the required creasing position, the servo motor 401 in the adjustment mechanism 400 is activated. The output shaft of the servo motor 401 rotates, causing the rotating rod 402 to rotate synchronously. Due to their hinged connection, the second connecting rods 403 at both ends of the rotating rod 402 change position as the rotating rod 402 rotates, thereby pushing the two sets of fixed rods 405 to slide relative to each other within the limiting groove 404. The creasing plates 106 fixed to the fixed rods 405 move accordingly until the spacing of the creasing plates 106 precisely corresponds to the desired creasing position on the cardboard. At this point, the servo motor 401 stops rotating. After completing the cardboard clamping and creasing plate 106 spacing adjustment, the hydraulic rod 107 is activated. The hydraulic rod 107 pushes the mounting plate 108 downwards, and the mounting plate 108 moves the creasing plates 106 downwards. When the creasing plates 106 contact the cardboard, pressure continues to be applied, pressing the desired mark onto the cardboard. During the creasing process, the clamping mechanism 200 continuously limits the cardboard to prevent it from moving or tilting, ensuring the accuracy and consistency of the creasing. The spring column 303 and the first connecting rod 301 in the limiting assembly 300 are adaptively adjusted according to the force on the paperboard to ensure effective limiting of the upper surface of the paperboard, while the pressure roller 302 adapts to the small displacement that the paperboard may produce by rotating, reducing the impact of friction on the position of the paperboard.
