Abstract
Description
Technical Field
[0001] This utility model relates to the field of folding machine technology, and in particular to an anti-detachment folding mechanism for folding machines. Background Technology
[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 lacks a structure to prevent paper from detaching. If the gap between the paper and the machine is too large, the paper will curl up, which will affect the folding efficiency. Utility Model Content
[0004] The purpose of this invention is to provide an anti-detachment folding mechanism for folding machines.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A folding machine anti-detachment folding mechanism includes a bracket, a support fixedly connected to the outer side of the bracket, a support plate disposed inside the support, a slide rod fixedly connected to the outer side of the support plate, a screw inserted into the inside of the support, a nut disposed on the outer side of the screw, a bearing disposed between the screw and the support plate, and a roller rotatably connected to the outer side of the support plate.
[0007] By adopting the above technical solution, a structure for limiting the paper is added near the folding mechanism. The paper follows the conveying component into the folding mechanism. At this time, a structure for limiting the paper on both the top and bottom sides is installed to limit the paper on both the top and bottom sides. At the same time, it can be adjusted adaptively according to the needs of use. The two sets of limiting structures are adjusted to ensure that the gap size of the paper is appropriate and convenient to use.
[0008] Furthermore, a fixing plate is fixedly connected to the outer side of the bracket, a fixing rod is fixedly connected to the outer side of the fixing plate, an electric telescopic rod is fixedly connected to the inside of the fixing rod, a folding knife is fixedly connected to the telescopic end of the electric telescopic rod, and a conveying assembly is fixedly connected to the inside of the bracket.
[0009] By adopting the above technical solution, the folding knife is controlled by an electric telescopic rod to achieve the folding function, which is convenient for use in conjunction with the paper anti-detachment structure.
[0010] Furthermore, the conveying assembly includes connecting blocks, a drive shaft, a drive belt, and a motor. The drive shaft is arranged between the connecting blocks, the drive belt is sleeved on the outside of the drive shaft, and the motor is fixedly connected to the outside of the connecting blocks.
[0011] By adopting the above technical solution, the transmission shaft is rotated by a motor, which drives the transmission belt on the outside of the transmission shaft to achieve transmission operation and transport the paper.
[0012] Furthermore, the support, support plate, slide rod, screw rod, nut, bearing and roller are symmetrically arranged in two groups. Each group has two support plates, two screw rods and two bearings, four slide rods and four nuts, and eight rollers. The slide rod and support are slidably connected, the screw rod and support are threadedly connected, the screw rod and nut are threadedly connected, and the screw rod and support plate are rotatably connected through bearings.
[0013] By adopting the above technical solution, the rotation of the screw can drive the support plate and rollers to move up and down. The use of the slide bar makes the overall structure move up and down more smoothly. After the position is determined, the structure is locked with nuts to prevent the position from shifting during use.
[0014] Furthermore, the transmission end of the motor is connected to one end of the transmission shaft, the transmission shaft is connected to the transmission belt, the transmission shaft is rotatably connected to the connecting block, and the connecting block is fixedly connected to the bracket.
[0015] By adopting the above technical solution, the transmission shaft and transmission belt driven by the motor can be used to achieve the conveying function, which facilitates the conveying of paper to the folding section.
[0016] In summary, the beneficial technical effects of this utility model are as follows:
[0017] It employs a support, screw, and rollers, and adds manually adjustable limiting and protective structures on the top and bottom sides of the paper. The gap between the rollers, i.e., the gap through which the paper passes, can be controlled by rotating the screw and sliding the slider, allowing for adaptive adjustment. The rollers can rotate to prevent pulling between them and the paper, avoiding paper jams. At the same time, the manual adjustment structure is simple and practical, allowing for quick gap adjustment according to the paper thickness. The overall structure prevents the paper from curling excessively during folding, improving folding efficiency and resulting in a convenient user experience. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.
[0023] Reference Figure 1-3 A folding mechanism for a folding machine with anti-detachment features includes a support 1, a base 2 fixedly connected to the outside of the support 1, a support plate 3 inside the base 2, a slide rod 4 fixedly connected to the outside of the support plate 3, a screw 5 inserted into the inside of the base 2, a nut 6 on the outside of the screw 5, a bearing 7 between the screw 5 and the support plate 3, a roller 8 rotatably connected to the outside of the support plate 3, a fixing plate 9 fixedly connected to the outside of the support 1, a fixing rod 10 fixedly connected to the outside of the fixing plate 9, an electric telescopic rod 11 fixedly connected inside the fixing rod 10, a folding knife 12 fixedly connected to the telescopic end of the electric telescopic rod 11, and a conveying assembly 13 fixedly connected inside the support 1. A structure for limiting the paper is added near the folding mechanism. The paper enters the folding mechanism along with the conveying assembly 13. At this time, the structure for limiting the paper on both the top and bottom surfaces is installed to limit the paper's movement. The two sets of limiting structures can be adjusted adaptively according to usage needs to ensure that the gap between the paper and the paper is appropriately sized for convenient use.
[0024] like Figure 1-3As shown, the conveying assembly 13 internally includes connecting blocks 131, a drive shaft 132, a drive belt 133, and a motor 134. The drive shaft 132 is positioned between the connecting blocks 131, and the drive belt 133 is sleeved on the outside of the drive shaft 132. The motor 134 is fixedly connected to the outside of the connecting blocks 131. Supports 2, support plates 3, slide rods 4, screws 5, nuts 6, bearings 7, and rollers 8 are symmetrically arranged in two sets. Each set has two support plates 3, two screws 5, and two bearings 7; each set has four slide rods 4 and four nuts 6; and each set has eight rollers 8. The slide rods 4 and support 2 are slidably connected, and the screws 5 and support 2 are screwed together. The screw 5 and nut 6 are threaded together. The screw 5 and support plate 3 are rotatably connected by bearing 7. The transmission end of motor 134 is connected to one end of transmission shaft 132. Transmission shaft 132 is connected to transmission belt 133. Transmission shaft 132 is rotatably connected to connecting block 131. Connecting block 131 is fixedly connected to bracket 1. By rotating screw 5, support plate 3 and roller 8 can be moved up and down. Slide rod 4 is used in conjunction to make the overall structure move up and down more smoothly. After the position is determined, the structure is locked by nut 6 to prevent position deviation during use and ensure the stability of the structure.
[0025] The implementation principle of this embodiment is as follows: In order to prevent the paper from curling up significantly during folding, the screw 5 can be manually rotated first. The rotation of the screw 5 and the cooperation of the slide bar 4 can drive the support plate 3 and the rollers 8 to move up and down. The two sets of symmetrical structures can be adjusted according to the thickness of the paper to ensure that the gap between the two sets of rollers 8 allows the paper to pass through smoothly. At the same time, the rollers 8 can rotate to prevent pulling between them and the paper, avoid paper jams, and improve folding efficiency. Then, the paper is transported to the conveying component 13. At this time, the motor 134 drives the transmission shaft 132 and the transmission belt 133 to transport the paper to the position of the folding knife 12. The electric telescopic rod 11 controls the folding knife 12 to move up and down to fold the paper.
[0026] 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.
