Description
Technical Field
[0001] This utility model relates to the field of creasing machine technology, and in particular to a creasing mechanism for carton processing that is easy to position. Background Technology
[0002] A creasing mechanism for carton processing, commonly known as a creasing machine, is an important piece of equipment used in carton production lines to pre-crease cardboard. It mainly uses components such as upper and lower pressure rollers, creasing knives or rollers to apply uniform pressure to the cardboard and press out preset crease lines at designated positions. This facilitates subsequent folding and forming, ensures accurate carton dimensions, neat creases, and prevents cracking, and improves the appearance and stacking strength of the finished carton. Traditional creasing machines rely on upper limit rollers to transmit, limit, and hold the cardboard when processing cardboard of different thicknesses. However, due to the large variation in cardboard thickness, operators need to frequently and repeatedly adjust the height of the upper limit rollers to ensure accurate positioning. The adjustment process is cumbersome and inefficient, which seriously affects the continuity of production and the convenience of order change. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a convenient positioning creasing mechanism for carton processing, comprising a conveyor and further comprising: a positioning component, wherein a gap is formed between the positioning component and the conveyor for cardboard to pass through; and a pressing component, wherein the pressing component is fixedly installed in the middle of the conveyor and performs a creasing action on the passing cardboard; wherein the positioning component includes a mounting frame fixed to the upper part of the conveyor, a connecting frame is rotatably mounted on the upper part of the mounting frame via a torsion spring, and a pressure roller is mounted on the lower part of the connecting frame for adapting to cardboard of different thicknesses.
[0005] In at least some embodiments, the conveyor includes a support frame with drive rollers rotatably mounted on both sides of the support frame, and the two drive rollers are connected by a drive belt.
[0006] In at least some embodiments, a drive motor is fixedly installed on one side of the support frame, the output end of the drive motor is fixedly connected to one of the transmission rollers, and each transmission roller has an annular groove on its outside. Multiple transmission belts are provided, and the contact portions of the multiple transmission belts and the transmission rollers are located in the annular grooves to achieve limit transmission.
[0007] In at least some embodiments, the mounting bracket includes support seats fixed to both sides of the support frame, and square rods are fixedly connected to the inner sides of the two support seats.
[0008] In at least some embodiments, a sleeve is mounted on the upper part of the square rod by means of a screw for sliding limit, and the connecting frame is mounted on the outside of the sleeve by means of a torsion spring.
[0009] In at least some embodiments, the pressing assembly includes a lift fixedly installed in the conveyor, a lifting frame fixedly installed on the lifting part of the lift, two sliding plates slidably installed inside the lifting frame, a bidirectional lead screw rotatably installed inside the lifting frame and screwed to the two sliding plates, and an output end of an adjusting motor fixedly installed on one side of the lifting frame is fixedly connected to the lead screw, and a mounting plate is fixedly installed on the lower part of each sliding plate by a spring telescopic rod, and a pressing plate for contacting the cardboard is fixedly installed on the lower part of the mounting plate by screws.
[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, the positioning component set above the conveyor and the pressing component in the middle work together to achieve precise indentation positioning and stable transmission of the cardboard. The positioning component consists of a mounting frame fixed on the upper part of the conveyor, a connecting frame rotatably connected by a torsion spring, and a pressure roller installed on the lower part of the connecting frame. When cardboard of different thicknesses passes by, the pressure roller can adaptively float up and down according to the thickness of the cardboard under the action of the torsion spring, always applying appropriate holding force to the cardboard, so that the cardboard is stable in the vertical position during the transmission process and will not jump or deviate. This avoids the tedious manual adjustment of height required by traditional limit rollers, effectively improving the efficiency of order changeover and positioning accuracy when processing multi-specification cardboard. While the cardboard is being transported stably, it completes the creasing action when passing through the pressing component located in the middle of the conveyor. The creasing position is accurate and the lines are clear, ensuring smooth subsequent folding. The entire process does not require frequent machine stops for adjustment, making it suitable for continuous, multi-batch carton production scenarios, greatly improving the automation and convenience of the production line.

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.
[0015] Implementation examples, based on Figures 1-4 As shown in the figure, the present invention provides a convenient positioning creasing mechanism for carton processing, including a conveyor and a positioning component 5, wherein a gap is formed between the positioning component 5 and the conveyor for cardboard to pass through; a pressing component, which is fixedly installed in the middle of the conveyor and performs a creasing action on the cardboard passing through; wherein the positioning component 5 includes a mounting frame fixed to the upper part of the conveyor, a connecting frame 504 is rotatably mounted on the upper part of the mounting frame via a torsion spring, and a pressure roller 505 is mounted on the lower part of the connecting frame 504 for adapting to cardboard of different thicknesses.
[0016] The aforementioned convenient creasing mechanism for carton processing achieves precise creasing positioning and stable transmission of cardboard through the cooperation of a positioning component 5 located above the conveyor and a pressing component in the middle. The positioning component 5 consists of a mounting frame fixed to the upper part of the conveyor, a connecting frame 504 rotatably connected by a torsion spring, and a pressure roller 505 installed below the connecting frame 504. When cardboard of different thicknesses passes by, the pressure roller 505 can adaptively float up and down according to the thickness of the cardboard under the action of the torsion spring, always applying appropriate holding force to the cardboard, so that the vertical position of the cardboard is stable during the transmission process, without jumping or deviating. This avoids the tedious operation of repeatedly adjusting the height manually required by traditional limit rollers, effectively improving the order change efficiency and positioning accuracy when processing multi-specification cardboard. While the cardboard is being transmitted stably, it completes the creasing action when passing through the pressing component located in the middle of the conveyor. The creasing position is accurate and the lines are clear, ensuring smooth subsequent folding.
[0017] In this embodiment, the transmission machine includes a support frame 1, with transmission rollers 2 rotatably mounted on both sides of the support frame 1. The two transmission rollers 2 are connected by a transmission belt 3. A drive motor 4 is fixedly mounted on one side of the support frame 1. The output end of the drive motor 4 is fixedly connected to one of the transmission rollers 2. Each transmission roller 2 has an annular groove on its outside. Multiple transmission belts 3 are provided. The contact parts of the multiple transmission belts 3 and the transmission rollers 2 are located in the annular grooves to achieve limit transmission.
[0018] The conveyor consists of a support frame 1, transmission rollers 2, transmission belts 3 and a drive motor 4. Transmission rollers 2 are rotatably mounted on both sides of the support frame 1 and are connected by multiple transmission belts 3. The drive motor 4 is fixedly mounted on one side of the support frame 1 and its output end is fixedly connected to one of the transmission rollers 2. When the motor is working, it drives the transmission roller 2 to rotate, thereby realizing the continuous conveying of the cardboard through the transmission belt 3. To prevent the transmission belt 3 from running off-track and to ensure stable and reliable operation, each transmission roller 2 has an annular groove on its outside. During transmission, the contact part between the transmission belt 3 and the transmission roller 2 is limited within the annular groove, so that the transmission belt 3 always runs along the predetermined track. This avoids unstable conveying or jamming caused by deviation, and ensures that the cardboard is subjected to uniform force and accurate position during conveying. This provides a stable conveying foundation for subsequent creasing or other processing steps, effectively improving the overall conveying accuracy and operational continuity of the machine.
[0019] In this embodiment, the mounting frame includes support seats 501 fixed on both sides of the support frame 1. Square rods 502 are fixedly connected to the inner sides of the two support seats 501. A sleeve 503 is installed on the upper part of the square rod 502 through a screw for sliding limit. The connecting frame 504 is installed on the outside of the sleeve 503 through a torsion spring.
[0020] The mounting frame consists of support seats 501 fixed on both sides of the support frame 1 and square rods 502 connected to its inner side. A sleeve 503 is installed on the upper part of the square rod 502 by a screw for sliding limit. The sleeve 503 can be adjusted and fixed along the position of the square rod 502. The connecting frame 504 is rotatably installed on the outside of the sleeve 503 by a torsion spring, so that the pressure roller 505 driven by the connecting frame 504 can swing up and down adaptively with the thickness of the cardboard, ensuring stable cardboard limit and convenient operation and adjustment.
[0021] In this embodiment, the pressing assembly includes a lift 6 fixedly installed in the conveyor. The lifting part of the lift 6 is fixedly installed with a lifting frame 7. Two slide plates 10 are slidably installed inside the lifting frame 7. A bidirectional lead screw 9 rotatably installed inside the lifting frame 7 is screwed to the two slide plates 10. The output end of an adjusting motor 8 fixedly installed on one side of the lifting frame 7 is fixedly connected to the lead screw. Each slide plate 10 has a mounting plate 12 fixedly installed on its lower part by a spring telescopic rod 11. A pressing plate 13 for contacting the cardboard is fixedly installed on the lower part of the mounting plate 12 by screws.
[0022] The pressing assembly consists of a lift 6, a lifting frame 7, a double-acting screw 9, a sliding plate 10, and a pressing plate 13, all fixedly installed in the conveyor. The lifting part of the lift 6 drives the entire lifting frame 7 to move up and down to adjust the height of the pressing assembly to adapt to different working conditions. Two sliding plates 10 are slidably installed inside the lifting frame 7, and are connected to the two sliding plates 10 by rotating the double-acting screw 9 installed inside the lifting frame 7. When the adjusting motor 8 drives the lead screw to rotate in both directions, it can simultaneously push the two sliding plates 10 to slide in opposite directions or in the same direction, thereby adjusting the distance between the two pressing plates 13 to adapt to the creasing requirements of cardboard of different thicknesses or sizes. Each slide plate 10 is connected to the mounting plate 12 via a spring telescopic rod 11 at its lower part. The mounting plate 12 is fixedly mounted to the pressing plate 13 via screws. The spring telescopic rod 11 can buffer and protect the cardboard during the pressing process, avoiding damage to the paper surface due to excessive pressing force. Meanwhile, when the processing technology requires it, one of the pressing plates 13 can be disassembled as needed to realize the flexible switching of single and double pressing plates 13 to meet various production conditions and improve the applicability and ease of operation of the equipment.
[0023] The working principle of this utility model is as follows: the positioning component 5 set above the conveyor cooperates with the pressing component in the middle to achieve precise indentation positioning and stable transmission of the cardboard. The positioning component 5 consists of a mounting frame fixed on the upper part of the conveyor, a connecting frame 504 rotatably connected by a torsion spring, and a pressure roller 505 installed on the lower part of the connecting frame 504. When cardboard of different thicknesses passes by, the pressure roller 505 can adaptively float up and down according to the thickness of the cardboard under the action of the torsion spring, and always apply appropriate holding force to the cardboard, so that the vertical position of the cardboard is stable during the transmission process and will not jump or deviate.
[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
