Description
Technical Field
[0001] This utility model relates to the field of paper processing technology, specifically to a paper folding device. Background Technology
[0002] The formal name for paper folding equipment is folding machine, also often called paper folding machine or paper folding machine. It is an automated processing equipment specially designed to automatically fold single or continuously fed sheets of paper into one or more halves according to preset size and position, so as to realize the neat folding of paper into shape. The core is to automatically and accurately fold the paper into two halves and the specified creases, replacing manual folding. It belongs to the category of special machinery for printing post-processing, packaging and office paper processing.
[0003] Existing folding equipment mostly uses a fixed, integrated adjustment mechanism, making it difficult to independently adjust the bending height and horizontal bending point. Thick paper is prone to wrinkling during bending, while thin paper has blurred creases. It is not compatible with various types of paper products such as roll paper, non-woven fabric, and packaging paper, resulting in a narrow range of applications and cumbersome paper changing and debugging. Furthermore, the equipment lacks lateral limiting plates, which can easily cause wide-width roll paper to shift left and right or move sideways during high-speed conveying and folding, leading to uneven folds and misaligned paper edges. Utility Model Content
[0004] The purpose of this invention is to provide a paper folding device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper folding device, comprising a device frame, a horizontal column, and a base. The horizontal column is installed on the inner wall of the device frame, and the base is slidably connected to the outer wall of the horizontal column. A horizontal adjustment mechanism is provided on one side of the outer wall of the base, and a height adjustment mechanism is provided on the other side. A guide seat is provided below the base, and a guide rod is connected inside the guide seat. A top guide column is connected to the bottom end of the outer wall of the base, and a vertical column is slidably connected inside the top guide column. A bottom guide column is fixedly connected to the bottom end of the vertical column. A sliding block is fixedly connected to the middle of the top of the top guide column. A sliding groove corresponding to the sliding block is opened inside the base, and a screw is threadedly connected inside the sliding block. A bolt is threadedly connected to the bottom end of the top guide column, and a limiting hole corresponding to the bolt is opened inside the vertical column. The column with bolts is used to adjust the height of the bottom guide column; the slide with screws can move the top guide column horizontally to adjust the distance between the bottom guide column and the guide seat.
[0006] Preferably, the screw and the base are connected by a thread, the top guide post and the slide are combined in an "L" shape, and the center of the top guide post is provided with a corresponding anti-movement cavity, and one side of the outer wall of the screw can extend into the limiting hole.
[0007] By rotating the screw, the slide block can be moved horizontally along the slide groove, causing the top guide column to move horizontally, thereby adjusting the horizontal distance between the bottom guide column and the guide seat; the operator can screw the bolt into the limiting holes of different heights to achieve the height positioning of the column, thereby adjusting the vertical bending height of the bottom guide column.
[0008] Preferably, a guide post is connected to one side of the middle part of the bottom guide post, and the guide post and the bottom guide post are combined in an "L" shape. A threaded post is threaded inside the guide post, and a limit plate is fixedly connected to one side of the outer wall of the threaded post.
[0009] Preferably, the limiting plate is circular and is used to limit the side edge of the paper, and the threaded post is used to adjust the distance between the limiting plate and the guide post.
[0010] The limiting plate is used to fit the side of the paper and to laterally limit the paper feeding process, preventing the paper from deviating or tilting. By rotating the threaded column, the distance between the limiting plate and the guide column can be adjusted to adapt to the side positioning of paper with different widths.
[0011] As can be seen from the above, the paper folding device provided by this utility model has the following beneficial effects.
[0012] The horizontal bending position can be independently fine-tuned through the screw and slide structure, and the vertical bending height can be independently adjusted through the bolt and limit hole structure. The horizontal and vertical adjustments do not interfere with each other, and it can be adapted to roll paper, packaging paper and non-woven fabric of different thicknesses, weights and widths, thus improving the adaptability of the equipment.
[0013] The positioning is achieved by locking the bolts with multiple sets of limiting holes, and by cooperating with the vertical guiding structure of the top guide column and the column to prevent the bending mechanism from having no displacement or shaking after adjustment; at the same time, a circular limiting plate is added to limit the paper laterally, so as to avoid the paper from deviating, wrinkling, and skewed creases when the paper is fed at high speed, thereby improving the folding accuracy and product qualification rate.

[0016] 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.
[0017] Please see Figures 1-5 This utility model provides a technical solution: a paper folding device, including a device frame 1, a horizontal column 2 and a base 3. The horizontal column 2 is installed on the inner wall of the device frame 1, and the base 3 is slidably connected to the outer wall of the horizontal column 2. A horizontal adjustment mechanism 4 is provided on one side of the outer wall of the base 3, and a height adjustment mechanism 5 is provided on the other side. A guide seat 6 is provided below the base 3. A guide rod 7 is connected inside the guide seat 6. A top guide column 8 is connected to the bottom end of the outer wall of the base 3. A column 9 is slidably connected inside the top guide column 8, and a bottom guide column 10 is fixedly connected to the bottom end of the column 9. A slide seat 11 is fixedly connected to the middle of the top end of the top guide column 8. A sliding groove corresponding to the slide seat 11 is opened inside the base 3, and a screw 12 is threadedly connected inside the slide seat 11. A bolt 13 is threadedly connected to the bottom end of the top guide column 8, and a limiting hole 14 corresponding to the bolt 13 is opened inside the column 9. The column 9, in conjunction with bolt 13, is used to adjust the height of the bottom guide column 10; the slide 11, in conjunction with screw 12, can horizontally move the top guide column 8 to adjust the distance between the bottom guide column 10 and the guide seat 6. The screw 12 is threadedly connected to the base 3. The top guide post 8 and the slide 11 are combined in an "L" shape, and the top guide post 8 has a corresponding anti-movement cavity in its center. One side of the outer wall of the screw 12 can extend into the limiting hole 14. The bottom guide post 10 is connected to a guide post 15 in the middle, and the guide post 15 and the bottom guide post 10 are combined in an "L" shape. The guide post 15 is threadedly connected to a threaded post 16. One side of the outer wall of the threaded post 16 is fixedly connected to a limiting plate 17. The limiting plate 17 is circular and is used to limit the side of the paper. The threaded post 16 is used to adjust the distance between the limiting plate 17 and the guide post 15.
[0018] For specific implementation, please refer to Figure 1The horizontal adjustment mechanism 4 allows the base 3 to slide along the horizontal column 2, thereby locking and fine-tuning the overall horizontal position of the base 3; the height adjustment mechanism 5 enables the vertical lifting and lowering adjustment of the folding mechanism; the guide seat 6, together with the guide rod 7, plays a role in vertical guidance, support and limiting of the overall folding execution unit.
[0019] See Figure 2 and Figure 3 By rotating the screw 12, the slide block 11 can be driven to slide horizontally along the slide groove, so that the top guide post 8 moves horizontally, thereby adjusting the horizontal distance between the bottom guide post 10 and the guide seat 6. The bottom guide post 10 is the core actuator for paper bending and pressing.
[0020] See Figure 4 and Figure 5 Since multiple sets of limiting holes 14 corresponding to bolts 13 are opened in the vertical direction inside the column 9, the staff can screw the bolts 13 into the limiting holes 14 at different heights to achieve the height positioning of the column 9, thereby adjusting the vertical bending height of the bottom guide column 10. The limiting plate 17 is used to fit the side of the paper and to laterally limit the paper feeding process to prevent the paper from deviating or tilting. By rotating the threaded column 16, the distance between the limiting plate 17 and the guide column 15 can be adjusted to adapt to the side positioning of paper with different widths.
[0021] In actual operation, based on the width, thickness, and weight of the paper to be processed, the horizontal position of the base 3 on the horizontal column 2 is first adjusted by the horizontal adjustment mechanism 4 to determine the overall folding position; the screw 12 is rotated to drive the slide 11 to move horizontally, adjusting the horizontal bending position of the bottom guide column 10; the bolt 13 is loosened, the column 9 is slid up and down, and the bolt 13 is locked to the corresponding limiting hole 14 to complete the vertical bending height adjustment of the bottom guide column 10; the threaded column 16 is rotated to adjust the lateral limiting distance of the limiting plate 17 to complete the side limiting of the paper. After the equipment is started, the roll of paper is fed into the equipment frame 1 at a uniform speed. The bottom guide column 10 cooperates with the guide seat 6 to fold the paper in half. The limiting plate 17 constrains the paper edge in real time to ensure that the crease is straight and the fold is neat.
[0022] This solution achieves independent fine-tuning of the horizontal bending position through the screw 12 and slide 11 structure, and achieves independent adjustment of the vertical bending height through the bolt 13 and limiting hole 14 structure. The horizontal and vertical adjustments do not interfere with each other, and can be adapted to roll paper, packaging paper and non-woven fabric of different thicknesses, weights and widths, thus improving the adaptability of the equipment.
[0023] The bolts 13 and multiple sets of limiting holes 14 are used for locking and positioning. Together with the vertical guiding structure of the top guide column 8 and the column 9, it prevents the bending mechanism from having no displacement or shaking after adjustment. At the same time, a circular limiting plate 17 is added to limit the paper laterally, so as to avoid the paper from deviating, wrinkling, and skewing when the paper is fed at high speed, thereby improving the folding accuracy and product qualification rate.
[0024] Each adjustment component is assembled independently in a modular fashion, and can be disassembled and replaced individually, which facilitates daily cleaning of paper scraps, inspection and replacement of vulnerable parts, and improves the ease of use of the equipment.
[0025] In practice, the staff operates the horizontal adjustment mechanism 4 to make the base 3 slide left and right along the horizontal column 2. According to the width of the paper to be processed, the horizontal installation position of the overall folding unit of the base 3 is determined. After completion, the horizontal adjustment mechanism 4 is locked to achieve the overall position positioning. The vertical height of the folding unit is finely adjusted by the height adjustment mechanism 5. Then, the screw 12 is rotated to drive the slide 11 to move horizontally in the slide groove of the base 3, and simultaneously drive the top guide column 8, column 9 and bottom guide column 10 to move horizontally. The horizontal distance between the bottom guide column 10 and the guide seat 6 is adjusted to determine the position of the paper folding center line.
[0026] Loosen bolt 13, slide column 9 up and down, and adjust the vertical bending height of bottom guide column 10 according to paper thickness: increase bending height for thick paper and decrease bending height for thin paper; after adjustment, screw bolt 13 into the corresponding height limiting hole 14 of column 9 and lock it in place; rotate threaded column 16 to drive limiting plate 17 to move horizontally, adjust the distance between limiting plate 17 and guide column 15 so that limiting plate 17 fits the side of paper, adapts to the current paper width, and constrains the left and right deviation of paper.
[0027] The roll of paper is then fed into the equipment frame 1, so that the paper passes through the guide seat 6, the bottom guide post 10, and the limiting plate 17 in sequence to complete the paper threading and centering. The equipment is started, and the roll of paper is conveyed forward at a uniform speed. The bottom guide post 10 works with the guide seat 6 to continuously bend and fold the paper. During the operation, the limiting plate 17 continuously limits the side of the paper, corrects the paper deviation in real time, and ensures that the creases are straight and the folds are aligned.
[0028] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
