Description

Technical Field

[0001] The present application relates to the technical field of rectification, and specifically to a wide-format printing rectification structure. Background Art

[0002] Wide-format printing refers to the printing activity using printing equipment and techniques capable of printing materials with a relatively wide format. These devices usually have large printing cylinders or printing platforms, which can print products with larger sizes at one time, thereby improving production efficiency and reducing costs.

[0003] The main function of the wide-format printing rectification structure is to detect and correct the offset of printing materials (such as paper) during transmission. Due to the influence of various factors (such as uneven material tension, mechanical vibration, etc.), the wide-format printing materials may be offset during transmission, resulting in inaccurate printing positions. The wide-format printing rectification structure ensures the printing accuracy and quality by real-time monitoring the position of the material and automatically adjusting the transmission path to make the material return to the correct position.

[0004] For example, the patent with the publication number CN218057638U specifically discloses a printing paper positioning and rectification structure for printed products. In this patent, by setting limit plates, the printing paper transported forward by the conveyor belt is likely to be offset during transportation due to the vibration of the conveyor belt. The limit plates on both sides position the outer surfaces of both sides of the printing paper through the limitation of their own shapes, thereby ensuring that the printing paper will not be offset during transportation on the conveyor belt.

[0005] During the actual printing process, under continuous rectification processing, the materials in the wide-format printing process may have insufficient tension. However, insufficient tension may cause the materials to wrinkle and slack, thereby leading to low printing efficiency.

[0006] Therefore, it is necessary to provide a wide-format printing rectification structure to solve the above problems.

[0007] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of the present application, and therefore, it may include information that does not constitute prior art. Summary of the Invention

Detailed Description of the Embodiments

[0034] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to elaborate on the present application in detail.

[0035] In order to enable those skilled in the art to better understand the solution of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0036] Such as Figures 1-3As shown in the figure, the present application provides a wide-width printing deviation correction structure, including a frame body 1 and deviation correction mechanisms 2 fixedly arranged on both sides of the frame body 1. The deviation correction mechanisms 2 are suitable for correcting the lateral position deviation generated during the movement of the material to avoid deviation during the printing process;

[0037] The deviation correction mechanism 2 includes lifting components fixedly arranged on both sides of the frame body 1. The lifting components are suitable for the deviation correction mechanism 2 to adjust different tensions, so as to prevent the material from becoming slack during transmission, thereby avoiding the resulting offset and wrinkles;

[0038] The lifting components include two groups of support frames 20 fixedly arranged on both sides of the frame body 1. A support platform 21 is fixedly arranged at the upper end of the support frame 20. At the same time, a first cylinder 22 is fixedly arranged inside the support platform 21. The first cylinder 22 is suitable for providing power for the lifting components. At the same time, a transmission component 23 is fixedly arranged at the output end of the first cylinder 22;

[0039] The transmission component 23 is suitable for correcting the lateral position deviation generated during the movement of the material. The transmission component 23 includes two groups of sliding units fixedly connected to the output end of the first cylinder 22;

[0040] Each sliding unit includes two groups of sliding platforms 230 fixedly connected to the output end of the first cylinder 22. A plurality of connecting rods 231 are fixedly arranged inside the sliding platform 230. At the same time, a slider 237 is slidably arranged on the connecting rod 231. An active piece 232 is rotatably arranged on the slider 237. At the same time, a deviation correction roller 233 is arranged between the two groups of sliding units. The deviation correction roller 233 is rotatably connected to the active piece 232. The deviation correction roller 233 is suitable for directly contacting the material;

[0041] The two groups of sliding units are suitable for the slider 237 to slide back and forth on the sliding platform 230. The two groups of sliding units are inclined. At the same time, the length of the deviation correction roller 233 remains unchanged. Thus, the angle of the deviation correction roller 233 can be changed by the rotational connection between the active piece 232 and the slider 237, so that the deviation correction roller 233 can directly contact the material, thereby changing the advancing direction of the material;

[0042] At the same time, a connection platform 234 is fixedly arranged at one end of one of the sliding platforms 230. A second cylinder 235 is fixedly arranged on the connection platform 234. At the same time, the output end of the second cylinder 235 is fixedly connected to the slider 237. The second cylinder 235 is suitable for providing the power source for the transmission component 23;

[0043] It should be noted that since the two sets of sliding units are inclined, and the deviation rectifying roller 233 has a fixed length, when the second cylinder 235 drives the sliding unit to move, the deviation rectifying roller 233 can be angularly offset, so that when the material transportation position deviates, the deviation rectifying effect can be achieved by continuously changing the angle of the deviation rectifying roller 233 until the material transportation position returns to normal;

[0044] As Figure 1 and Figure 4 shown, a tensioning mechanism 5 is fixedly arranged at the upper end of the frame body 1 away from the deviation rectifying mechanism 2, and the tensioning mechanism 5 is suitable for ensuring that the material in progress does not affect the next processing of the material;

[0045] The tensioning mechanism 5 includes a bracket 51 fixedly arranged at the upper end of the frame body 1. A plurality of groups of slideways (not marked in the figure) are vertically opened on the bracket 51. At the same time, a plurality of groups of tensioning rollers 54 are arranged between the brackets 51, and the tensioning rollers 54 are suitable for tensioning the material;

[0046] And movable blocks 56 are rotatably arranged at both ends of the tensioning roller 54. A sliding wheel 55 is fixedly arranged on the movable block 56. The sliding wheel 55 is slidably arranged on the bracket 51. The sliding wheel 55 is adapted to a plurality of groups of vertically opened slideways on the bracket 51. At the same time, a motor (not shown in the figure) is fixedly arranged inside the sliding wheel 55, and the output end of the motor is fixedly connected to the sliding wheel 55, so that the motor can drive the sliding wheel 55 to drive the tensioning roller 54 to slide up and down on the slideway;

[0047] It should be noted that when the lifting assembly starts to operate to adjust the different tensions of the material, the motor drives the sliding wheel 55 to move along the direction of the slideway, so as to synchronously tension the material with the deviation rectifying mechanism 2 during the progress of the material, so that the material in progress does not affect the next processing of the material;

[0048] At the same time, a printing device 4 is fixedly arranged on one side of the frame body 1 away from the deviation rectifying mechanism 2. The printing device 4 is a relief printing structure in the prior art, so as to perform printing operations on the material passing through the printing device 4.

[0049] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
