Description

Technical Field

[0001] The utility model relates to the technical field of scanners, in particular to a paper alignment mechanism of a document scanner. Background Art

[0002] Document scanners are mainly used to scan documents. They can quickly input our paper documents instantly, and can quickly convert scanned images into editable documents through OCR text recognition function, thereby greatly improving office efficiency.

[0003] When using an existing large scanner, the document is first placed in a paper feeder, and then the paper feeder sends the paper to the scanning table. When the scanner needs to scan and print the document, in order to align the printed document layout, the paper needs to be aligned. However, most existing paper feeders are only used to carry and store paper and cannot align the paper. Therefore, before placing the paper in the paper feeder, manual alignment is required. At the same time, when placing the paper in the paper feeder, the paper may be messed up, thereby affecting the printing effect. For this reason, we propose a paper alignment mechanism for a document scanner to solve the above problem. Utility Model Content

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] Reference Figure 1-5 A paper alignment mechanism of a document scanner includes a scanner body 1, a paper alignment structure 2 is provided on one side of the scanner body 1, the paper alignment structure 2 includes a bearing component 3 and a knocking and vibrating component 4, and the knocking and vibrating component 4 is located below the bearing component 3, and the knocking and vibrating component 4 is located on one side of a rotating component 302, the bearing component 3 includes a bearing component 301, and a rotating component 302 and a limiting component 303 are provided on the bearing component 301.

[0030] The bearing assembly 301 includes a bearing plate 3011, which is tilted. A first baffle 3012 is slidably connected to the bearing plate 3011, and a second baffle 3013 is fixedly connected to the bearing plate 3011. The baffle is used to limit the position of the paper to prevent it from slipping. The first baffle 3012 corresponds to the second baffle 3013, and the first baffle 3012 and the second baffle 3013 are respectively located at two ends of the bearing plate 3011. The first baffle 3012 and the second baffle 3013 are the same size, and the length of the bearing plate 3011 is greater than the maximum distance between the first baffle 3012 and the second baffle 3013.

[0031] The rotating assembly 302 includes a motor No. 1 3021 fixedly connected to the scanner body 1. The motor No. 1 3021 is a prior art and will not be described in detail herein. The output end of the motor No. 1 3021 is fixedly connected to a fixed block 3022 and a half gear 3023, and one end of the fixed block 3022 is fixedly connected to the supporting plate 3011, and the fixed block 3022 is located on the center line of the supporting plate 3011.

[0032] The limiting component 303 includes an L-shaped plate 3031 which is slidably connected to the second baffle plate 3013. The L-shaped plate 3031 can be used as a baffle, not only for connecting the pressure plate 3032, but also for blocking and limiting the paper. The top of the L-shaped plate 3031 is fixedly connected with the pressure plate 3032, and the pressure plate 3032 corresponds to the supporting plate 3011. The pressure plate 3031 can be used in conjunction with the supporting plate 3011 to limit the paper. A spring 3033 is fixedly connected between the L-shaped plate 3031 and the supporting plate 3011, and the spring 3033 will pull the pressure plate 3031 downward.

[0033] The knocking vibration component 4 includes a rotating shaft 401 rotatably connected to the scanner body 1, a driven wheel 402 and a ring 403 are fixedly connected to the outer surface of the rotating shaft 401, and the driven wheel 402 is meshed with the half gear 3023, a reset spring 404 is sleeved on the outer surface of the rotating shaft 401, and the two ends of the reset spring 404 are respectively fixedly connected to the scanner body 1 and the ring 403, one end of the rotating shaft 401 is fixedly connected to a rotating plate 405, the position of the rotating plate 405 exceeds the fixed block 3022, and the rotating plate 405 corresponds to the supporting plate 3011.

[0034] When in use, pull the pressure plate 3032 upwards, then the L-shaped plate 3031 will move upwards along the second baffle 3013 and pull the spring 3033, and then place the paper on the carrier plate 3011. Since the carrier plate 3011 is tilted, the paper will slide down until one end of the paper slides to one end of the carrier plate 3011. In the normal state, the paper will be limited by the limiting structure in the scanner. The limiting structure is a prior art and will not be described in detail here. Therefore, the paper will not slide into the scanner, and then release the pressure plate 3032. At this time, the pressure plate 3032 will move downward under the action of its own gravity and the elastic force of the spring 3033 and press the paper.

[0035] At this time, the output end of motor No. 1 3021 will rotate with the fixed block 3022, and when the fixed block 3022 rotates, it will rotate with the supporting plate 3011, so the supporting component 301 and the limiting component 303 will rotate at the same time. During the rotation, one end of the No. 1 baffle 3012 will tilt upward, and the paper will slide toward the No. 2 baffle 3013, and the No. 1 baffle 3012 will slide toward the No. 2 baffle 3013 under the action of its own gravity, thereby limiting one side of the paper.

[0036] At the same time, when the first motor 3021 rotates, it will rotate with the half gear 3023. Since the half gear 3023 is meshed with the driven wheel 402, the first motor 3021 will rotate with the shaft 401. When the shaft 401 rotates, it will rotate with the ring 403 and the rotating plate 405. When the ring 403 rotates, it will rotate with one end of the return spring 404, so that the return spring 404 is twisted and deformed. When the gear teeth on the half gear 3023 separate from the driven wheel 402, the shaft 401 will rotate back under the restoring force of the return spring 404. Therefore, the rotating plate 405 will rotate toward the supporting plate 3011 and collide with the supporting plate 3011, thereby causing the supporting plate 3011 to vibrate, and the supporting plate 3011 will vibrate with the paper when vibrating, and the paper will move toward the scanner and the second baffle 3013 when vibrating, so that multiple papers are gradually aligned, and then the first motor 3021 will return the supporting plate 3011 to its original position. During the rotation of the supporting plate 3011, since one end of the first baffle 3012 is higher than one end of the second baffle 3013, the paper will not slide with the rotation of the supporting plate 3011.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
