[0002] Folding machines are mainly used for folding various sizes and thicknesses of paper within the design range. They are suitable for high-speed printing centers, manufacturing enterprises, official documents, and business letters for large-volume folding. Their main function is to fold various types of paper to make the paper neater, more beautiful, and easier to carry and manage.
[0003] The existing technical solutions mentioned above have the following drawbacks: the folding mechanism inside the existing folding machine has a structure that limits the paper edges, which cannot be adjusted adaptively and is therefore limited in use. Utility Model Content
[0004] The purpose of this invention is to provide a folding mechanism for a folding machine that is easy to adjust.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A folding mechanism for a conveniently adjustable folding machine includes a support, a first oblong hole inside the support, an edge limiting plate on the outer side of the support, a second oblong hole inside the edge limiting plate, a first screw inserted inside the edge limiting plate, a first nut on the outer side of the first screw, an upper limiting plate on the outer side of the edge limiting plate, a second screw inserted inside the upper limiting plate, and a second nut on the outer side of the second screw.
[0007] By adopting the above technical solution, and by designing the edge limiting plate and the upper limiting plate as a sliding and adjustable structure, the limiting plate can be adaptively adjusted according to different paper thicknesses and widths, ensuring that the paper can enter the folding structure flat and that the folding operation can be carried out normally.
[0008] Furthermore, a fixed seat is fixedly connected to the outer side of the support, a fixed rod is fixedly connected to the outer side of the fixed seat, an electric telescopic rod is fixedly connected to the inside of the fixed rod, a folding knife is fixedly connected to the telescopic end of the electric telescopic rod, and a conveying mechanism is fixedly connected to the inside of the support.
[0009] By adopting the above technical solution, the electric telescopic rod drives the folding knife to rise and fall, thereby realizing the folding operation.
[0010] Furthermore, the conveying mechanism includes a connecting seat, a drive shaft, a drive belt, and a motor. The drive shaft is rotatably connected between the connecting seats. A drive belt is sleeved on the outside of the drive shaft. A motor is fixedly connected to the outside of the connecting seats. The output end of the motor is fixedly connected to one end of the drive shaft.
[0011] By adopting the above technical solution, the paper can be transported to the folding mechanism by the motor driving the transmission shaft and transmission belt.
[0012] Furthermore, the first waist-shaped hole, the side limiting plate, the second waist-shaped hole, the first screw, the first nut, the upper limiting plate, the second screw, and the second nut are symmetrically arranged in two sets. Each set has two sets of the first waist-shaped hole, the second waist-shaped hole, the second screw, and the first screw, and each set has four sets of the first nut and the second nut.
[0013] By adopting the above technical solution and through the design of a symmetrical structure, the stability of the two sides of the structure can be improved, ensuring that the paper enters the folding mechanism flat and stably on both sides.
[0014] Furthermore, the first screw passes through the side limiting plate and the first waist-shaped hole and extends to the outside of the first waist-shaped hole. The first screw and the first nut are threadedly connected. The second screw passes through the second waist-shaped hole and the upper limit plate and extends to the outside of the upper limit plate. The second screw and the second nut are threadedly connected. The connecting seat and the support are fixedly connected.
[0015] By adopting the above technical solution, the limiting plate can be moved and adjusted along the waist-shaped hole through the cooperation between the screw and the nut, and then locked and fixed by the screw and the nut. The width can be adjusted adaptively according to the thickness of different papers. The structure is simple and practical.
[0016] In summary, the beneficial technical effects of this utility model are as follows:
[0017] 1. The device uses a side limiting plate, a first screw, and a first nut. By moving the side limiting plate along the position of the first waist-shaped hole, the distance between the two sides can be adjusted according to the width of different papers. After adjustment, the first screw and the first nut are locked to lock and fix the side limiting plate, which can facilitate the adjustment of the side.
[0018] 2. An upper limit plate, a second screw, and a second nut are used. The upper limit plate is moved along the position of the second oblong hole, and the vertical spacing is adjusted. The height of the upper limit plate can be adjusted according to different paper thicknesses, so that the paper can enter the device better, prevent the upper end from curling, ensure stable folding, and produce a convenient effect.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] Reference Figure 1-5 A folding mechanism for a conveniently adjustable folding machine includes a support 1, a first oblong hole 2 inside the support 1, an edge limiting plate 3 on the outer side of the support 1, a second oblong hole 4 inside the edge limiting plate 3, a first screw 5 inserted inside the edge limiting plate 3, a first nut 6 on the outer side of the first screw 5, an upper limiting plate 7 on the outer side of the edge limiting plate 3, a second screw 8 inserted inside the upper limiting plate 7, a second nut 9 on the outer side of the second screw 8, and a fixed seat fixedly connected to the outer side of the support 1. 10. A fixing rod 11 is fixedly connected to the outside of the fixing base 10. An electric telescopic rod 12 is fixedly connected to the inside of the fixing rod 11. A folding knife 13 is fixedly connected to the telescopic end of the electric telescopic rod 12. A conveying mechanism 14 is fixedly connected to the inside of the support 1. By designing the side limiting plate 3 and the upper limiting plate 7 as a sliding adjustment structure, the limiting plate can be adjusted adaptively according to different paper thicknesses and widths to ensure that the paper can enter the folding structure flat and that the folding operation can be carried out normally.
[0027] like Figure 1-5As shown, the conveying mechanism 14 internally includes a connecting seat 141, a drive shaft 142, a drive belt 143, and a motor 144. The drive shaft 142 is rotatably connected between the connecting seats 141. The drive belt 143 is sleeved on the outside of the drive shaft 142. The motor 144 is fixedly connected to the outside of the connecting seats 141. The output end of the motor 144 is fixedly connected to one end of the drive shaft 142. The mechanism includes a first oblong hole 2, a side limiting plate 3, a second oblong hole 4, a first screw 5, a first nut 6, an upper limiting plate 7, a second screw 8, and a second nut 9. Two sets of symmetrically arranged components are provided. Each set contains two sets of first oblong holes 2, two oblong holes 4, two second screws 8, and two first screws 5. Each set also contains four sets of first nuts 6 and two second nuts 9. The first screw 5 passes through the edge limiting plate 3 and extends to the outside of the first oblong hole 2, and is threadedly connected to the first nut 6. The second screw 8 passes through the second oblong hole 4 and extends to the outside of the upper limit plate 7, and is threadedly connected to the second nut 9. The connecting seat 141 and the support 1 are fixedly connected. The engagement between the screws and nuts allows the limiting plate to move and adjust along the oblong holes, and then is locked in place by the screws and nuts. The width can be adaptively adjusted according to the thickness of different papers, facilitating operation.
[0028] The implementation principle of this embodiment is as follows: The device is adjusted according to the width and thickness of the paper. First, the edge limiting plate 3 is moved along the first waist-shaped hole 2 and adjusted according to the width of the paper. Then, the first screw 5 is passed through the first waist-shaped hole 2 and locked and fixed by the first nut 6. After the width is determined, the upper limit plate 7 is moved along the second waist-shaped hole 4 and adjusted according to the thickness of the paper. After the adjustment is completed, the second screw 8 is passed through the second waist-shaped hole 4 and locked and fixed by the second nut 9. This ensures that the paper can enter the folding part more stably and flatly when folding.
[0029] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
