Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paper cutting and processing, in particular to a paper cutting size positioning mechanism. Background Art
[0002] During the production process of printing and packaging, the printing machine has a requirement for the size error of paper of 0.2 - 0.3 millimeters. If the paper size error exceeds the required range, it will directly affect the normal production of the printing machine.
[0003] Before the paper is cut by the upper paper cutter, edge alignment and positioning are required to ensure the dimensional accuracy after cutting. However, in the existing alignment and positioning methods, generally, a large stack of papers is manually pushed towards the baffle for multiple adjustment and pushing to achieve alignment and positioning. During the process of pushing the papers towards the baffle, when the pushing force is too large, some papers will bounce back, and when the pushing force is too small, some papers will not be pushed in place. Therefore, whether the pushing force of the papers is too large or too small, it is easy to cause the wrong size of the cut papers. Moreover, in the process of manual pushing for alignment and positioning, due to the inability to accurately judge with the naked eye, the cutting production efficiency is not high and the cutting size quality is unstable, resulting in the printing machine being unable to be normally put into production.
[0004] Therefore, we provide a paper cutting size positioning mechanism. Summary of the Utility Model

A positioning instrument is installed at the lower end of the detection support frame. An auxiliary frame is installed outside the detection support frame. A support block is installed outside the auxiliary frame. A rotating rod is rotatably installed inside the support block. The rotating rod is inserted with a spiral connection semi-ring. There are at least two spiral connection semi-rings, and they are located at symmetric positions. A rotating screw is installed between the two spiral connection semi-rings. The spiral connection semi-ring is in threaded engagement with the rotating screw. Opposite ends of the rotating screw are rotatably installed on one side of the cutting frame.
[0007] Preferably, the half of the moving guide plate away from the cutting frame is inserted into the auxiliary frame, and the auxiliary frame is slidably connected to the moving guide plate.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.
[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
[0024] Embodiment: A paper cutting size positioning mechanism, as Figures 1-4As shown in the figure, it includes a cutting frame 15, and a moving guide plate 1 installed on one side of the cutting frame 15. A guide rail 2 is provided inside the moving guide plate 1. A detection support frame 3 is slidably installed inside the guide rail 2. A positioning instrument 4 is installed at the lower end of the detection support frame 3. An auxiliary frame 5 is installed outside the detection support frame 3. A support block 6 is installed outside the auxiliary frame 5. A rotating rod 7 is rotatably installed inside the support block 6. A spiral connection half-ring 8 is inserted into the rotating rod 7. There are at least two spiral connection half-rings 8, and they are located at symmetric positions. A rotating stud 12 is installed between the two spiral connection half-rings 8. The spiral connection half-ring 8 is in threaded engagement with the rotating stud 12. Opposite ends of the rotating stud 12 are rotatably installed on one side of the cutting frame 15. When the device is in use, first rotate the rotating stud 12, so that the two spiral connection half-rings 8 are simultaneously driven to rotate and move horizontally on the outside of the rotating stud 12. The movement of the spiral connection half-ring 8 synchronously adjusts the distance of the auxiliary frame 5, and finally achieves the effect of adjusting the position of the detection support frame 3. And control the spiral connection half-ring 8 to rotate in the vertical direction, so that the two spiral connection half-rings 8 are disengaged from the range connected to the rotating stud 12, so that the detection support frame 3 at the current position can be stably used. Then adjust the two spiral connection half-rings 8 on one side of the detection support frame 3 at different positions so that they are connected to the rotating stud 12, achieving the effect of finely adjusting the position of the detection support frame 3. Thus, by rotating a rotating stud 12, the detection support frames 3 at different positions can be adjusted separately. And under the support of the guide rail 2, the detection support frame 3 can be directly moved for large-range adjustment, so as to facilitate timely adjustment of the detection position of the positioning instrument 4, making the device convenient for accurately aligning and positioning different specifications of paper. And by setting the model of the positioning instrument 4 as RL650-50G detection support frame 3, the accuracy during alignment and positioning is guaranteed.
[0025] As Figures 1-4 shown, the half part of the moving guide plate 1 away from the cutting frame 15 is inserted into the auxiliary frame 5, and the auxiliary frame 5 is slidably connected to the moving guide plate 1. By arranging the auxiliary frame 5 outside the moving guide plate 1, a guiding frame is formed with the detection support frame 3. When the auxiliary frame 5 drives the detection support frame 3 to move, under the limit support of the moving guide plate 1, the accuracy of the moving direction of the auxiliary frame 5 itself is guaranteed, thereby further improving the accuracy and stability of the movement of the devices on both sides of the auxiliary frame 5.
[0026] As Figures 1-4As shown in the figure, at least two rotating rods 7 are rotatably installed on the inner wall of the support block 6. The two rotating rods 7 are respectively inserted into the spiral connection half-rings 8. The spiral connection half-rings 8 are snap-connected to the support block 6. A limiting plate 9 is installed on the outer side of one end of the spiral connection half-ring 8 away from the rotating rod 7. There are at least two limiting plates 9. A fastening groove 11 is formed on one side of the upper limiting plate 9, and a fastening frame 10 is inserted into the lower limiting plate 9. The fastening frame 10 is simultaneously inserted into the fastening groove 11. Under the rotational support of the rotating rod 7, the spiral connection half-ring 8 is rotated. When the two spiral connection half-rings 8 come into contact, the fastening frame 10 is moved so that it is simultaneously inserted into the two limiting plates 9, achieving the effect of limiting the two spiral connection half-rings 8, thereby ensuring its stability during movement. After the movement is accurate, by rotating the spiral connection half-ring 8 in the reverse direction, it is snap-connected to the support block 6 to prevent it from falling, ensuring its firmness when used in a fixed position, and further improving the stability of the movement and use of the detection device.
[0027] As Figures 1-4 shown in the figure, a plurality of support grooves 14 are formed on one side of the moving guide plate 1. A closing frame 13 is inserted into the support grooves 14. The closing frame 13 is simultaneously inserted into the guide rail 2. By setting the closing frame 13 to be simultaneously inserted into the moving guide plate 1 and the guide rail 2, the number of detection support frames 3 and locators 4 can be adjusted when the closing frame 13 is moved out, enabling it to position papers of different shapes and improving the applicability of the device.
[0028] Working principle: After placing the paper on one side of the cutting frame 15, rotate the rotating stud 12, so that the two spiral connection half-rings 8 are simultaneously driven to rotate and move horizontally on the outer side of the rotating stud 12. The movement of the spiral connection half-rings 8 synchronously adjusts the distance of the auxiliary frame 5, and finally achieves the effect of adjusting the position of the detection support frame 3. And control the spiral connection half-ring 8 to rotate in the vertical direction, separate the two spiral connection half-rings 8 from the range connected to the rotating stud 12, so that the detection support frame 3 at the current position can be stably used. Then close the two spiral connection half-rings 8 on the other side, rotate the rotating stud 12 again, adjust the position of the other detection support frame 3, and make the two locators 4 operate simultaneously, achieving the effect of aligning and positioning the paper, so that the device is convenient for accurately aligning and positioning papers of different specifications.
[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
