Abstract
Description
Technical Field
[0001] This utility model relates to the field of multi-part blank paper printing technology, and in particular to a multi-part blank paper correction module. Background Technology
[0002] Multi-part blank printing paper is frequently used in financial invoices, report output, and data processing. When this type of paper is fed in a continuous printer, it often deviates due to uneven paper thickness, edge cutting errors, or inconsistent friction, which can easily lead to skewed or overlapping printed content, or even paper jams.
[0003] The aforementioned existing technical solutions have the following drawbacks: In the existing technology, some printers are equipped with structures such as guide wheels and paper pressure rollers to limit paper deviation, but most of them are only suitable for single-layer or thinner printing paper, and are not suitable for multi-part blank printing paper. During long-term or high-speed printing, the correction ability of these structures is limited, and they cannot effectively ensure the stable direction of the paper. Some correction devices have complex structures, are inconvenient to install, and are not conducive to widespread application. Utility Model Content
[0004] The purpose of this invention is to provide a multi-part blank printing paper correction module to solve the problems existing in the prior art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A multi-part blank printing paper correction module includes a base, a placement frame fixedly installed at the top left end of the base, a conveyor roller fixedly installed at the top of the base with its axis arranged front-to-back, a first mounting plate fixedly installed at the left end of the base, a second mounting plate fixedly installed at the front end of the first mounting plate with its rear end face abutting against the front end face of the first mounting plate, a third mounting plate fixedly installed at the rear end of the first mounting plate with its front end face abutting against the rear end face of the first mounting plate, a plurality of connecting rods fixedly installed inside the base, a plurality of connecting rods fixedly installed between the second and third mounting plates with their axes arranged front-to-back, a drive module fixedly installed on the front side of the top of the third mounting plate, and a first correction mechanism and a second correction mechanism fixedly installed on the front side of the right end of the third mounting plate.
[0007] By adopting the above technical solution, precise positioning and orientation correction of multi-part blank printing paper can be achieved during the conveying process. This effectively solves the problem of paper skew caused by factors such as uneven paper stacking, deviation in conveyor roller speed, or the material characteristics of the paper itself. It ensures that the paper maintains the correct path in subsequent printing and copying processes, significantly improving the positional accuracy of the printed content and avoiding quality defects such as content offset, ghosting, or missing content. Secondly, the coordinated operation of the dual correction mechanisms can significantly improve the response speed and processing capacity of the correction. When the paper is slightly offset, the first correction mechanism can make a preliminary and rapid adjustment. If the offset is large or the offset trend continues, the second correction mechanism can provide a stronger correction force, forming a double guarantee to prevent paper jams due to untimely correction during high-speed conveying. This improves the operational stability and continuity of the entire printing system, reduces equipment downtime for maintenance, and increases work efficiency.
[0008] In a further embodiment, a slide rail is fixedly installed on the right end of the top of the second mounting plate, a slide rail is fixedly installed on the right end of the top of the third mounting plate, and a position sensor is fixedly installed between the slide rails.
[0009] By adopting the above technical solution, the position sensor is installed between the slide rails, which can directly and continuously sense the specific position information of the moving parts on the slide rails, ensuring the timeliness and accuracy of the monitoring data, and providing reliable position feedback for the automated control of the equipment.
[0010] In a further embodiment, the drive module includes a first cylinder, a drive motor, an upper conveying roller, a lower conveying roller, and a fourth mounting plate. The first cylinder is symmetrically fixedly mounted on the top of the second and third mounting plates. The axis of the first cylinder is vertically arranged. The fourth mounting plate is fixedly mounted on the bottom of the first cylinder. The upper conveying roller is inserted into the fourth mounting plate. The lower conveying roller is located at the bottom of the upper conveying roller. The two ends of the lower conveying roller are respectively inserted into the second and third mounting plates. The drive motor is fixedly mounted on the front side of the third mounting plate. The axis of the drive motor is arranged front and rear. The front end of the drive motor is rotatably connected to the lower conveying roller.
[0011] By adopting the above technical solution, this direct connection method can minimize energy loss during power transmission and ensure that the torque output by the drive motor can be efficiently transmitted to the lower conveyor roller, thereby improving the energy utilization efficiency of the entire conveying system.
[0012] In a further embodiment, the first correction mechanism includes a first conveying roller, a second cylinder, and a first correction conveying roller. The second cylinder is fixedly installed on the front side of the bottom end of the third mounting plate. The axis of the second cylinder is arranged front to back. The first correction conveying roller is fixedly installed at the front end of the second cylinder. The axis of the first correction conveying roller is collinear with the axis of the second cylinder. The first conveying roller is fixedly installed between the second mounting plate and the third mounting plate. The first conveying roller is located to the left of the first correction conveying roller. The axis of the first conveying roller is arranged front to back.
[0013] By adopting the above technical solution, the components in the first correction mechanism are closely coordinated. Through reasonable position layout, axis design and power transmission method, accurate and efficient correction of the material's forward and backward position is achieved, ensuring the stability and accuracy of the material conveying process and improving the overall equipment's operating quality and production efficiency.
[0014] In a further embodiment, the second correction mechanism includes a second conveying roller, a third cylinder, and a second correction conveying roller. The third cylinder is fixedly installed on the front side of the top of the third mounting plate, and the axis of the third cylinder is arranged front to back. The front end of the third cylinder is fixedly installed with the second correction conveying roller, and the axis of the second correction conveying roller is collinear with the axis of the third cylinder. The second conveying roller is fixedly installed between the second mounting plate and the third mounting plate, and the second conveying roller is located to the left of the first correction conveying roller. The axis of the second conveying roller is arranged front to back.
[0015] By adopting the above technical solution, the components of the second correction mechanism are closely coordinated. Through reasonable position layout, axis design and power transmission method, accurate and efficient correction of the material's forward and backward position is achieved, ensuring the stability and accuracy of the material conveying process and improving the overall equipment's operating quality and production efficiency.
[0016] In a further embodiment, feet are fixedly installed at both the left and right ends of the bottom of the second mounting plate, and feet are fixedly installed at both the left and right ends of the bottom of the third mounting plate, with the axis of the feet being vertically set.
[0017] By adopting the above technical solution, it can be ensured that the supporting force of the foot cup on the mounting plate is perpendicular to the ground, so that the weight of the mounting plate and the entire equipment is evenly and stably transferred to the ground through the foot cup. This effectively avoids the problem of uneven force distribution caused by the tilt of the supporting force direction, thereby enhancing the overall stability of the equipment when it is placed and reducing the risk of tipping over.

[0019] 1. The connecting rod design ensures a more secure connection between the base, the second mounting plate, and the third mounting plate.
[0020] 2. The corrective structure ensures that multiple blank printing sheets do not shift during transport;
[0021] 3. By setting up a position sensor, it is possible to provide timely feedback on whether the paper feed has deviated. Attached Figure Description
