Description

Technical Field

[0001] This utility model relates to the field of cardboard box creasing technology, and in particular to a cardboard box creasing folding device. Background Technology

[0002] The definition of carton creasing refers to the process of using creasing tools to press marks or leave bendable grooves on cardboard or other materials. Creasing tools mainly include steel wire and creasing wheels. These tools are arranged and combined to form a template, which processes the cardboard under pressure. Creasing is one of the important means of forming cartons, boxes, and other packaging materials. Through creasing, the material can be bent and shaped according to a preset position, thereby improving the forming effect and stability of the packaging.

[0003] In related technologies, to facilitate quick disassembly and assembly of the creasing knife and adjustment of its installation position, for example, patent CN217495354U provides a longitudinal creasing and folding device for cartons. This device secures the fixing plate to the pressure roller by aligning the through hole with the screw hole and then rotating the fastening bolt to screw the bolt into the screw hole. With this structure, it is not only easy to quickly disassemble and assemble the fixing plate, thus facilitating the replacement and maintenance of the creasing knife, but also allows for adjustment of the installation position of the fixing plate. Although the above-mentioned prior art solutions can automatically convey cartons to press creasing lines longitudinally and adjust the installation position of the creasing knife, due to different cardboard sizes and the open feed inlet, the cardboard may deviate when entering the creasing equipment due to human operation, the flatness of the cardboard itself, or minor errors in the conveying system. The creasing position may not match the expected design, which may lead to inaccurate folding during carton forming, affecting the overall aesthetics and practicality. Therefore, a carton creasing and folding device has been proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6A cardboard creasing and folding device includes: a creasing body 1, the inner cavity of which is provided with a creasing element 2 for creasing and folding cardboard; a movable panel 3, which is movably disposed on the front side of the creasing body 1, and the surface of the movable panel 3 is provided with a correction hole 4 for cardboard to enter. The design of the movable panel 3 allows the operator to easily open or close the front side of the creasing body 1, facilitating equipment maintenance and upkeep. At the same time, the correction hole 4 on its surface provides a channel for cardboard to enter. The inner cavity of the correction hole 4 is provided with a correction element 5 and an adjusting element 6 for correcting the position of the cardboard. The correction element 5 includes two correction plates 51 movably connected to the inner cavity of the correction hole 4, and a moving plate 54 is provided on the opposite side of the two correction plates 51. The adjusting element 6 includes a locking block 62 that is synchronously linked with the correction plate 51 and multiple adjusting holes 61 provided on the front side of the movable panel 3 for the locking block 62 to be inserted. The top of the creasing body 1 is provided with a flipping element 7.

[0033] In this embodiment, the indentation component 2 includes a drive unit 21 fixedly installed on the outside of the indentation machine body 1. The drive unit 21 is specifically a motor. The output shaft of the drive unit 21 movably passes through the inner cavity of the indentation machine body 1 and is connected to the indentation roller 23. A guide roller 22 is installed in the inner cavity of the indentation machine body 1 and is located above the indentation roller 23. Multiple indentation knives 24 are bolted to the surface of the indentation roller 23. Multiple bolt holes are opened on the surface of the indentation roller 23 for mounting the indentation knives 24. The correction component 5 includes a slide 52 fixedly connected to the bottom of the correction plate 51. Guide rails 53 are opened on both sides of the bottom of the inner cavity of the correction hole 4 for the slide 52 to slide, so that the correction plate 51 can slide smoothly along the guide rails 53. A screw 55 is movably connected to one side of the moving plate 54. The surface of the screw 55 is threaded through the correction plate 51. A limiting rod 56 is fixedly connected to one side of the plate 54. The limiting rod 56 is movably connected to the correction plate 51. The moving plate 54 realizes the fine adjustment of the position of the correction plate 51, and the limiting rod 56 ensures the stability of the moving plate 54 during the adjustment process. This allows the operator to quickly adjust the position of the correction plate 51 according to the size of the cardboard and ensure the accuracy of the indentation. A movable rod 63 is movably connected to the front side of the slide 52. The front end of the movable rod 63 is fixedly connected to the locking block 62, and the rear end of the movable rod 63 is fixedly connected to the protrusion 64. A spring 65 is sleeved on the surface of the movable rod 63. One end of the spring 65 is fixedly connected to the inside of the slide 52, and the other end of the spring 65 is fixedly connected to the protrusion 64. Through the elastic force of the spring 65, the locking block 62 can be stably inserted into or pulled out of the adjustment hole 61, thereby realizing the fixation or adjustment of the position of the correction plate 51.

[0034] In the embodiments of this application, the flipping component 7 includes a rotating rod 71 movably connected to the front top of the creasing machine body 1. The surface of the rotating rod 71 is fixedly connected to the movable panel 3. A gear 72 is fixedly sleeved on one end of the surface of the rotating rod 71. A second drive unit 73 is fixedly installed on the top of the creasing machine body 1. The second drive unit 73 is specifically a cylinder. A toothed plate 74 is fixedly connected to the output end of the second drive unit 73. The toothed plate 74 meshes with the gear 72. After the movable panel 3 is flipped upward, the internal structure of the creasing machine body 1 is in an open state. When the equipment malfunctions, the open internal structure allows maintenance personnel to locate the problem more quickly and perform corresponding repairs or replace parts. When the movable panel 3 is located on the front side of the creasing machine body 1, it can guide the cardboard.

[0035] The following is the usage process of the cardboard creasing and folding device provided by this utility model: Cardboard enters the inner cavity of the creasing machine body 1 through the correction hole 4 for creasing. Since the cardboard size is different, the position of the moving plate 54 can be adjusted so that the distance between the two moving plates 54 is adapted to the size of the cardboard. First, the locking block 62 can be pulled outward so that one side of the locking block 62 is disengaged from the inner cavity of the adjustment hole 61, thereby unlocking the slide 52 and the correction plate 51. After the correction plate 51 is moved to the approximate position, one side of the locking block 62 is inserted back into the inner cavity of the corresponding adjustment hole 61 to lock it. Next, the screw 55 is rotated so that the moving plate 54 moves and the distance between the moving plate 54 and the correction plate 51 changes, thereby allowing fine adjustment of the distance between the two moving plates 54 to achieve the function of precise guidance when the cardboard enters. During maintenance, the drive unit 2 73 can be driven to move the toothed plate 74. The toothed plate 74 drives the gear 72, the rotating rod 71 and the movable panel 3 to rotate, flipping the movable panel 3 upward for easy maintenance.
