Technical Field

[0001] This utility model relates to the field of paper mounting machine technology, specifically a device for precise alignment of multi-layer paper in a paper mounting machine. Background Technology

[0002] In the current era of rapid development in the packaging and printing industry, the mounting machine, as the core equipment for producing corrugated cardboard, directly affects the quality of finished products and production efficiency due to the alignment accuracy of its multiple layers of paper. With the continuous improvement of requirements for cardboard flatness and graphic registration accuracy in fields such as e-commerce packaging and high-end gift boxes, the demand for cardboard flatness and graphic registration accuracy is increasing.

[0003] In existing technologies, traditional alignment methods mostly rely on mechanical guides and manual adjustment. Mechanical guides constrain the paper position through fixed physical limits. However, due to the differences in paper size between different batches and the fact that the paper is easily displaced by tension and friction when the mounting machine is running at high speed, mechanical guides are difficult to accurately adapt to all working conditions. Manual adjustment relies on the experience and skill of the operator, which is not only inefficient and difficult to meet the pace of large-scale continuous production, but also results in inconsistent alignment accuracy due to different operating standards among different personnel. Therefore, there is an urgent need for a precise alignment device for multi-layer paper in a mounting machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a precise alignment device for multi-layer paper in a paper mounting machine, so as to solve the problem that the traditional alignment method mentioned in the background art relies on mechanical gauges and manual adjustment, which is slow and has low alignment accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer paper precision alignment device for a paper mounting machine, comprising a front end of the paper mounting machine, wherein a conveyor table is slidably connected to the inner wall of the front end of the paper mounting machine, and a synchronous alignment component is provided on the inner wall of the conveyor table;

[0006] The synchronous alignment assembly includes a rotating column rotatably connected to the inner wall of the conveyor table.

The side walls of the multiple rack tubes are meshed with the surface of the spur gear. A placement plate is provided on the top surface of the conveyor table.

[0007] Preferably, the bottom surface of the conveyor table is provided with multiple limiting holes, and the inner walls of the multiple limiting holes are slidably connected to the same connecting frame. The upper end of the connecting frame is fixedly connected to the bottom surface of the placement plate. The bottom surface of the conveyor table is fixedly connected to a fixing frame, and the bottom surface of the fixing frame is fixedly connected to an electric telescopic cylinder. The output end of the electric telescopic cylinder is fixedly connected to the top surface of the connecting frame.

[0008] Preferably, the inner wall of the rack tube is rotatably connected to a threaded column, the surface of the threaded column is threadedly connected to a connecting block, the top surface of the connecting block is fixedly connected to the bottom surface of the telescopic frame, and the connecting block is slidably connected to the inner wall of the rack tube.

[0009] Preferably, the inner wall of the push frame is slidably connected to a retractable frame, the side wall of the retractable frame has two threaded grooves, the side wall of the push frame has two adjusting holes, the inner wall of the threaded groove is threaded with a bolt, and the surface of the bolt is movably sleeved with the inner wall of the adjusting hole.

[0011] Preferably, a motor is fixedly connected to the bottom surface of the fixed frame, and the surface of the rotating column is fixedly connected to the output end of the motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

The rotation of the rotating column then drives multiple rack tubes, telescopic frames, and push frames to move synchronously. The synchronous movement of the multiple push frames aligns the multiple layers of paper on the placement plate, thus improving the convenience of paper alignment. At the same time, the rotating column is located at the center of the conveyor table.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model provides a multi-layer paper precision alignment device for a mounting machine, including a front end 1 of the mounting machine. A conveyor table 2 is slidably connected to the inner wall of the front end 1. A synchronous alignment component 3 is provided on the inner wall of the conveyor table 2. The synchronous alignment component 3 includes a rotating column 301, which is rotatably connected to the inner wall of the conveyor table 2. A spur gear 302 is fixedly connected to the surface of the rotating column 301. Multiple rack tubes 303 are slidably connected to the bottom surface of the conveyor table 2. A telescopic frame 304 is slidably connected to the inner wall of the rack tubes 303. A pusher frame 305 is fixedly connected to the top surface of the telescopic frame 304. The side walls of the multiple rack tubes 303 mesh with the surface of the spur gear 302. The conveyor table 2 is connected to the top surface of which a placement plate 312 is provided. Through the provided synchronous alignment component 3, the rotation of the rotating column 301 can drive multiple rack tubes 303, telescopic frame 304 and push frame 305 to move synchronously. The synchronous movement of multiple push frames 305 can push the multi-layer paper on the surface of the placement plate 312 to align, thereby improving the convenience of paper alignment. At the same time, the rotating column 301 is located at the center of the conveyor table 2. When the rotating column 301 rotates, it drives multiple rotating columns 301 to move synchronously, which makes it easier for multiple push frames 305 to push the multi-layer paper towards the center of the placement plate 312 synchronously, thereby improving the accuracy of paper alignment.

[0022] Furthermore, the bottom surface of the conveyor table 2 is provided with multiple limiting holes 313, and the inner walls of the multiple limiting holes 313 are slidably connected to the same connecting frame 314. The upper end of the connecting frame 314 is fixedly connected to the bottom surface of the placement plate 312. The bottom surface of the conveyor table 2 is fixedly connected to a fixing frame 315, and the bottom surface of the fixing frame 315 is fixedly connected to an electric telescopic cylinder 316. The output end of the electric telescopic cylinder 316 is fixedly connected to the top surface of the connecting frame 314. By using the connecting frame 314, the fixing frame 315 and the electric telescopic cylinder 316 in cooperation, the telescopic end of the electric telescopic cylinder 316 can be retracted to drive the placement plate 312 to move upward. The upward movement of the placement plate 312 can facilitate the sequential forward conveying of multiple layers of paper after the surface of the placement plate 312 is aligned.

[0023] Furthermore, a threaded post 310 is rotatably connected to the inner wall of the rack tube 303, and a connecting block 311 is threadedly connected to the surface of the threaded post 310. The top surface of the connecting block 311 is fixedly connected to the bottom surface of the telescopic frame 304, and the connecting block 311 is slidably connected to the inner wall of the rack tube 303. The threaded post 310 and the connecting block 311 work together to make it easy to adjust the extension distance of the telescopic frame 304 according to the length and width of the paper.

[0024] Furthermore, a shrink frame 306 is slidably connected to the inner wall of the push frame 305. The side wall of the shrink frame 306 has two threaded grooves 307, and the side wall of the push frame 305 has two adjusting holes 308. A bolt 309 is threadedly connected to the inner wall of the threaded groove 307. The surface of the bolt 309 is movably sleeved with the inner wall of the adjusting hole 308. Through the cooperation of the shrink frame 306, the threaded groove 307 and the bolt 309, it is easy to adjust and fix the height of the shrink frame 306 extending from the push frame 305, thereby facilitating the alignment of multi-layered papers of different thicknesses.

[0025] Furthermore, the bottom surface of the conveyor table 2 is provided with multiple limiting grooves 317. The inner wall of the limiting groove 317 is slidably connected with two limiting blocks 318. The bottom surface of the two limiting blocks 318 is fixedly connected to the top surface of the rack tube 303. The limiting grooves 317 and the limiting blocks 318 cooperate with each other to facilitate the limiting of the rack tube 303 and facilitate the parallel movement of the rack tube 303.

[0026] Furthermore, a motor 319 is fixedly connected to the bottom surface of the fixed frame 315, and the surface of the rotating column 301 is fixedly connected to the output end of the motor 319. The motor 319 is provided so that the output end of the motor 319 can rotate, thereby facilitating the rotation of the rotating column 301.

[0027] Working principle: In use, the synchronous alignment component 3 is set so that the output end of the limit block 318 can rotate to drive the rotating column 301 to rotate. The rotation of the rotating column 301 can drive multiple rack tubes 303, telescopic frame 304 and push frame 305 to move synchronously. The synchronous movement of multiple push frames 305 can push the multi-layer paper on the surface of the placement plate 312 to align, thereby improving the convenience of paper alignment.

[0028] Meanwhile, the rotating column 301 is located at the center of the conveyor table 2. When the rotating column 301 rotates, it drives multiple rotating columns 301 to move synchronously, which makes it easier for multiple pushers 305 to push multiple layers of paper synchronously toward the center of the placement plate 312, thereby improving the accuracy of paper alignment.

[0029] Secondly, the threaded post 310, connecting block 311 and telescopic frame 304 work together to make it easy to adjust the extension distance of the telescopic frame 304 according to the length and width of the paper. After the adjustment is completed, when aligning, the distance from both sides to the center is always the same, so that the paper is always in the center of the placement plate 312 after alignment.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
