Technical Field
[0001] This utility model relates to the field of rotary printing press technology, specifically to a paper transport structure for a rotary printing press. Background Technology
[0002] Rotary printing presses are continuous printing devices that use a rotating drum. The drum's rotation evenly transfers ink onto the paper, enabling efficient batch printing. Its core component is the drum, which rotates continuously during printing. Computer control enables high-speed, automated operation. The rotary printing press stores ink in the drum and evenly spreads it onto the paper surface during rotation. The printing content is controlled directly by computer-transmitted commands, allowing for multi-color overlay printing. Paper transport in a rotary printing press refers to the process of transferring paper from the printing plate to the impression cylinder via rollers and a transmission device. To improve the efficiency of rotary printing presses, a new paper transport structure is needed; however, existing paper transport structures still have the following shortcomings:
[0003] When using existing paper transport structures, most of them lack a structure to limit the paper's position, which makes it easy for different types and sizes of paper to shift during the printing process. This results in unclear text printing, reduced practicality and efficiency of the paper transport structure. Utility Model Content
[0004] The purpose of this invention is to provide a paper transport structure for a rotary printing press 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 transport structure for a rotary printing press, comprising a worktable and a limiting component. A supporting column is installed at the bottom of the worktable. A limiting component is provided on the right side of the upper end of the worktable. The limiting component includes a mounting limiting groove, a cylinder, a limiting slider, a mounting frame, a spring damping rod, and a guide roller. A cylinder is installed inside the mounting limiting groove, and a limiting slider is installed at the front end of the cylinder. A mounting frame is installed on the upper end of the limiting slider. A spring damping rod is provided on the upper inner side of the mounting frame, and a guide roller is installed at the front end of the spring damping rod. A material conveying component is provided on the left side of the upper end of the worktable.
[0006] Furthermore, the cylinder and the limiting slider are arranged perpendicularly, and the cylinder and the limiting slider are fixedly connected by bolts.
[0007] Furthermore, the spring damping rod is perpendicular to the guide roller, and the guide roller is elastically connected to the mounting frame through the spring damping rod.
[0008] Furthermore, the number of guide rollers is set to four, and two guide rollers are grouped together, and each group of guide rollers is symmetrically arranged on both sides of the upper end of the worktable with respect to the side center axis of the worktable.
[0009] Furthermore, the feeding assembly includes a mounting frame, a return spring, and a movable slider. The return spring is installed at the upper end of the mounting frame, and the movable slider is installed at the front end of the return spring.
[0010] Furthermore, the feeding assembly also includes a receiving slider, a first feeding roller and a second feeding roller, and receiving sliders are added to both sides of the movable slider. At the same time, the first feeding roller is connected to the inner side of the movable slider, and the second feeding roller is distributed below the first feeding roller.
[0011] Furthermore, the reset spring and the movable slider are distributed perpendicularly, and the movable slider is elastically connected to the mounting frame through the reset spring.
[0012] Furthermore, the external dimensions of the movable slider are adapted to the internal dimensions of the mounting frame, and the movable slider and the mounting frame are embedded in each other.
[0013] This utility model provides a paper transport structure for a rotary printing press, which has the following advantages:
[0014] 1. This utility model, through the setting of the limiting component, enables the limiting slider to move in position when the paper transport structure of the rotary printing press is in use. The mounting frame is fixedly installed at the front end of the limiting slider. The movement of the limiting slider causes the mounting frame to adjust its position. The guide roller is elastically connected to the mounting frame through the spring damping rod. Thus, the mounting frame limits the paper while cooperating with the guide roller to limit the feeding, thereby avoiding positional deviation of the paper during the transport process and improving the overall practicality and efficiency of the paper transport structure.
[0015] 2. This utility model, through the setting of the feeding component, enables the movable slider to be elastically connected to the mounting frame via a return spring when the paper transport structure of the rotary printing press is in use. The external dimensions of the receiving sliders added to both sides of the movable slider are adapted to the internal dimensions of the grooves opened inside the mounting frame. Thus, when the movable slider moves elastically, the receiving sliders increase its stability during the movement process. The first feeding roller is limited and installed inside the movable slider. The elastic movement of the first feeding roller, together with the second feeding roller installed inside the worktable, limits and transports the paper, adjusts the paper tension, and improves the overall practicality and efficiency of the paper transport structure.

Detailed Implementation
[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] like Figures 1 to 3As shown, a paper transport structure for a rotary printing press includes a worktable 1 and a limiting component 3. Support legs 2 are mounted on the bottom of the worktable 1, and the limiting component 3 is located on the upper right side of the worktable 1. The limiting component 3 includes a mounting limiting groove 301, a cylinder 302, a limiting slider 303, a mounting frame 304, a spring damping rod 305, and a guide roller 306. The cylinder 302 is installed inside the mounting limiting groove 301, and the limiting slider 303 is mounted on the front end of the cylinder 302, thus limiting the paper transport. A mounting bracket 304 is installed on the upper end of the slider 303. A spring damping rod 305 is installed on the upper inner side of the mounting bracket 304. A guide roller 306 is installed at the front end of the spring damping rod 305. The cylinder 302 is perpendicular to the limiting slider 303 and is fixedly connected to the limiting slider 303 by bolts. The spring damping rod 305 is perpendicular to the guide roller 306, and the guide roller 306 is elastically connected to the mounting bracket 304 through the spring damping rod 305. The number of 06 is set to four, with two guide rollers 306 as a group. Each group of guide rollers 306 is symmetrically arranged on both sides of the upper end of the worktable 1 along the side center axis. The cylinder 302 is fixedly installed in the installation limiting groove 301 opened inside the worktable 1 by fastening bolts. The limiting slider 303 is fixedly installed at the front end of the cylinder 302 with the fastening bolts. The operation of the cylinder 302 drives the limiting slider 303 to move its position. The mounting frame 304 is fixedly installed at the front end of the limiting slider 303. The movement of the limiting slider 303 drives the mounting frame 304 to adjust its position. The spring damping rod 305 is fixedly installed on the upper inner side of the mounting frame 304. The spring damping rod 305 makes the guide roller 306 elastically connected to the mounting frame 304. Thus, the mounting frame 304 limits the paper while cooperating with the guide roller 306 to limit the feeding, thereby avoiding the position deviation of the paper during the transmission process and improving the overall practicality and efficiency of the paper transmission structure.
[0022] like Figure 1 and Figure 3As shown, a material conveying assembly 4 is provided on the upper left side of the workbench 1. The material conveying assembly 4 includes a mounting frame 401, a return spring 402, and a movable slider 403. The return spring 402 is installed at the upper end of the mounting frame 401, and the movable slider 403 is installed at the front end of the return spring 402. The material conveying assembly 4 also includes a receiving slider 404, a first conveying roller 405, and a second conveying roller 406. The receiving sliders 404 are added to both sides of the movable slider 403. The first conveying roller 405 is connected to the inner side of the movable slider 403, and the second conveying roller 406 is distributed below the first conveying roller 405. The return spring 402 is perpendicular to the movable slider 403, and the movable slider 403 is elastically connected to the mounting frame 401 through the return spring 402. The external dimensions of the movable slider 403 are adapted to the internal dimensions of the mounting frame 401, and the movable slider 403 is elastically connected to the mounting frame 401 through the return spring 402. The mounting frame 401 is embedded and fixed to both sides of the upper end of the workbench 1 by fastening bolts. The return spring 402 is also fixed to the upper part of the mounting frame 401 with the fastening bolts. The return spring 402 makes the movable slider 403 elastically connected to the mounting frame 401. The external dimensions of the receiving sliders 404 added to both sides of the movable slider 403 are adapted to the internal dimensions of the groove opened inside the mounting frame 401. Thus, when the movable slider 403 moves elastically, the receiving sliders 404 increase its stability during the movement. The first feeding roller 405 is limited and installed inside the movable slider 403. The elastic movement of the first feeding roller 405, together with the second feeding roller 406 installed inside the workbench 1, limits the feeding of paper, adjusts the tension of the paper, and improves the overall practicality and efficiency of the paper conveying structure.
[0023] In summary, the paper transport structure of this rotary printing press, during use, firstly, fixes the support column 2 to the bottom of the worktable 1 using fastening bolts, thereby increasing the stability of the worktable 1 during use. Then, the cylinder 302 drives the limit slider 303 to move, and the mounting frame 304 is fixedly installed at the front end of the limit slider 303. The movement of the limit slider 303 drives the mounting frame 304 to adjust its position. A spring damping rod 305 elastically connects the guide roller 306 to the mounting frame 304, thus limiting the paper position through the mounting frame 304 while simultaneously coordinating with the guide roller 306 to limit and transport the paper, thereby preventing misalignment during paper transport. The offset is then set, and the movable slider 403 is elastically connected to the mounting frame 401 by the return spring 402. The external dimensions of the receiving sliders 404 added on both sides of the movable slider 403 are adapted to the internal dimensions of the groove opened inside the mounting frame 401. Thus, when the movable slider 403 moves elastically, the receiving sliders 404 increase its stability during the movement process. The first feeding roller 405 is limited and installed inside the movable slider 403. The elastic movement of the first feeding roller 405, together with the second feeding roller 406 installed inside the worktable 1, limits the feeding of paper, adjusts the tension of the paper, and improves the overall practicality and efficiency of the paper conveying structure.
