[0002] A printer is a computer output device used to print computer processing results on relevant media, such as paper. The invention and development of printers have greatly changed the way information is recorded and disseminated. The core function of printers is to convert digital information into visual information on paper documents or other media. The main indicators for measuring printer performance include print resolution, print speed and noise level. There are many types of printers, which can be divided into impact and non-impact printers according to whether the printing element has an impact action on the paper.

[0034] A printer is a computer output device used to print computer processing results on relevant media, such as paper. The invention and development of printers have greatly changed the way information is recorded and disseminated. The core function of printers is to convert digital information into visual information on paper documents or other media. The main indicators for measuring printer performance include print resolution, print speed and noise level. There are many types of printers, which can be divided into impact and non-impact printers according to whether the printing element has an impact action on the paper. Among them, inkjet printers and laser printers are the most common types. Inkjet printers form images or text by spraying ink, while laser printers use laser scanning technology and electrophotography technology to print.

[0035] At present, when printing documents, it is often necessary to print multiple copies repeatedly. When existing printers print multiple copies of documents, because their paper output directions are consistent, the printed multiple copies of the documents will overlap together. However, since the multiple copies of the documents need to be distributed later, it is also necessary to manually separate the multiple overlapping documents, which is not only time-consuming and labor-intensive, but also greatly wastes human resources.

[0036] Therefore, in order to realize the rapid splitting of multiple printed documents, save splitting time, improve work efficiency, and avoid waste of human resources, this embodiment provides a paper sorting mechanism.

[0037] like Figures 1 to 4 As shown, the paper sorting mechanism includes a fixed bracket 10, a paper collection board 20 and a driving assembly 30. The paper collection board 20 is slidably arranged on the fixed bracket 10, and is used to carry paper. The driving assembly 30 includes a slider 301, a first rotating member 302, an eccentric shaft 303, a first rotating wheel 304 and a driving member 305. The slider 301 is provided with a sliding groove 3011 and is connected to the paper collection board 20. The first rotating member 302 is rotatably arranged in the sliding groove 3011. One end of the eccentric shaft 303 is rotatably connected to the first rotating member 302, and the other end of the eccentric shaft 303 is connected to the first rotating wheel 304 and is eccentrically distributed with respect to the center of the first rotating wheel 304. The driving member 305 is used to drive the first rotating wheel 304 to rotate.

[0038] By connecting the paper collection board 20 with the slider 301, and providing a first rotating member 302 that can rotate freely in the sliding groove 3011 in the sliding groove 3011 of the slider 301, when the driving member 305 drives the first rotating wheel 304 to rotate, the first rotating wheel 304 will drive the first rotating member 302 that is rotatably connected to the eccentric shaft 303 to rotate in the sliding groove 3011 while also revolving around the center of the first rotating wheel 304, thereby driving the slider 301 to drive the paper collection board 20 to slide back and forth at different positions on the fixed bracket 10, so that when paper is discharged, the paper falls on different positions of the paper collection board 20, thereby realizing automatic splitting of multiple documents without the need for subsequent manual splitting, saving time and effort, and greatly avoiding the waste of human resources.

[0039] Among them, the shape of the sliding groove 3011 can be adjusted according to needs. In this embodiment, the sliding groove 3011 is rectangular, and the slider 301 with the sliding groove 3011 is detachably connected to the paper collection board 20 through bolts, so as to facilitate the replacement of paper collection boards 20 of different specifications and models. In order to enable the first rotating member 302 to rotate freely in the sliding groove 3011, a bearing is used as the first rotating member 302, which is sleeved on the eccentric shaft 303.

[0040] In order to achieve accurate separation of multiple printed documents, a stepper motor is used as a driving component 305. When collecting paper, the control element PLC sends a control signal to control the driving component 305, so that when the printed documents are collected, the driving component 305 controls the eccentric shaft 303 to move a corresponding displacement, so that the slider 301 connected to the eccentric shaft 303 drives the receiving paper board 20 to move accordingly, thereby achieving a position change, so that after each complete printed document is collected, the position is adjusted once, so that multiple printed documents fall at different positions of the receiving paper board 20, achieving hierarchical overlap, thereby achieving automatic separation of multiple documents.

[0041] Alternatively, if Figure 4 As shown, the driving assembly 30 further includes a second rotating wheel 306 and a transmission member 307. The output shaft of the driving member 305 is plugged into the second rotating wheel 306 and is used to drive the second rotating wheel 306 to rotate. The transmission member 307 is used to transfer the torque of the second rotating wheel 306 to the first rotating wheel 304. The outer diameter of the first rotating wheel 304 is larger than the outer diameter of the second rotating wheel 306. By arranging the second rotating wheel 306 in the driving assembly 30 and making the outer diameter of the second rotating wheel 306 smaller than the outer diameter of the first rotating wheel 304, when the driving member 305 drives the second rotating wheel 306 to rotate, the transmission member 307 transfers the torque of the second rotating wheel 306 to the first rotating wheel 304, and then uses the first rotating wheel 304 to reduce the speed, so as to adjust the rotation speed and avoid excessive rotation speed.

[0042] In this embodiment, the outer diameters of the first rotating wheel 304 and the second rotating wheel 306 can be freely set according to requirements, so as to obtain a rotation speed that meets the use requirements.

[0043] Specifically, Figure 4 As shown, the first rotating wheel 304 and the second rotating wheel 306 are pulleys, and the transmission member 307 is a synchronous belt, and the transmission member 307 is sleeved on the outside of the first rotating wheel 304 and the second rotating wheel 306. By using the synchronous belt as the transmission member 307 and the pulley as the first rotating wheel 304 and the second rotating wheel 306, the torque transmission between the first rotating wheel 304 and the second rotating wheel 306 is realized by belt transmission, which has the advantages of shock absorption, noise reduction and overload protection.

[0044] Specifically, the first rotating wheel 304 and the second rotating wheel 306 are sprocket wheels, the transmission member 307 is a transmission chain, and the first rotating wheel 304 and the second rotating wheel 306 are both meshed with the transmission member 307. By using the transmission chain as the transmission member 307 and the sprocket wheels as the first rotating wheel 304 and the second rotating wheel 306, the torque transmission between the first rotating wheel 304 and the second rotating wheel 306 is realized by chain transmission, which has high transmission efficiency and overload resistance.

[0045] Alternatively, if Figure 3 As shown, the fixed bracket 10 also includes a plurality of rolling members 101, two spaced side panels 102 and a connecting plate 103, the connecting plate 103 is used to connect the two spaced side panels 102, the two side panels 102 are provided with a plurality of rotatable rolling members 101 on the side away from each other, and the paper collection board 20 is arranged above the two spaced side panels 102 and abuts against the rolling members 101. By arranging a plurality of rolling members 101 abutting against the paper collection board 20 on the side away from each other of the side panels 102, the paper collection board 20 can reduce the friction force with the fixed bracket 10 under the action of the rolling members 101, so that the paper collection board 20 can slide more smoothly along the length direction of the side panels 102. In this embodiment, the rolling member 101 is a roller, and the number of rolling members 101 arranged on each side panel 102 can be freely set according to demand.

[0046] Alternatively, if Figure 1 , Figure 3 As shown, the fixing bracket 10 further includes a limit block 104, which is disposed on one side of the two spaced side panels 102 facing each other, and a limit groove is formed on the limit block 104, in which the paper receiving paper 20 is disposed. By arranging the limit block 104 on the side of the side panels 102 facing each other and forming a limit groove on the limit block 104, the paper receiving paper 20 accommodated in the limit groove can be guided to slide.

[0047] Alternatively, if Figure 2 , Figure 3 As shown, a mounting through hole is provided on the connecting plate 103, and the fixing bracket 10 further includes a first fixing plate 105, which is connected to the connecting plate 103, and one end of the driving member 305 is connected to the first fixing plate 105, and the other end is passed through the mounting through hole. By providing a mounting through hole for the driving member 305 to pass through on the connecting plate 103, on the one hand, interference between the driving member 305 and the fixing bracket 10 is avoided during assembly, and on the other hand, the space overlap between the fixing bracket 10 and the driving member 305 can be achieved, thereby reducing the occupied space and making the structure more compact.

[0048] In this embodiment, the opening area of ​​the mounting through hole is larger than the volume of the driving member 305 , so during assembly, the mounting position of the driving member 305 can be adjusted, thereby providing ample adjustment space for assembly.

[0049] Alternatively, if Figure 2 , Figure 3As shown, the fixed bracket 10 further includes a second fixed plate 106, and the driving assembly 30 further includes a connecting shaft 308, a second rotating member 309 and a third rotating member 310. One end of the connecting shaft 308 is inserted into the first rotating wheel 304, and the other end of the connecting shaft 308 passes through the second fixed plate 106 and the connecting plate 103 in sequence. The second rotating member 309 is arranged between the connecting shaft 308 and the second fixed plate 106, and the third rotating member 310 is arranged between the connecting shaft 308 and the connecting plate 103. By inserting the connecting shaft 308 on the first fixed plate 105 and the connecting plate 103, the connecting shaft 308 is fixedly supported and the stability of the connecting shaft 308 is ensured. The second rotating member 309 is arranged between the connecting shaft 308 and the first fixed plate 105, and the third rotating member 310 is arranged between the connecting shaft 308 and the connecting plate 103, so that the connecting shaft 308 can freely rotate on the first fixed plate 105 and the connecting plate 103. In this embodiment, the second fixed plate 106 is connected to the connecting plate 103, and the first fixed plate 105 is connected to the second fixed plate 106, wherein the second fixed plate 106 is provided with an avoidance groove corresponding to the installation through hole, and the second rotating member 309 and the third rotating member 310 are both bearings.

[0050] Alternatively, if Figure 4 As shown, the driving assembly 30 further includes a first shaft end retaining ring 311 and a second shaft end retaining ring 312. The first shaft end retaining ring 311 is sleeved on the connecting shaft 308 and is located on the side of the second rotating member 309 away from the third rotating member 310. The second shaft end retaining ring 312 is sleeved on the connecting shaft 308 and is located on the side of the third rotating member 310 away from the second rotating member 309. By arranging the first shaft end retaining ring 311 on the side of the second rotating member 309 away from the third rotating member 310 and arranging the second shaft end retaining ring 312 on the side of the third rotating member 310 away from the second rotating member 309, the second rotating member 309 and the third rotating member 310 are respectively limited, thereby preventing the second rotating member 309 and the third rotating member 310 from positional displacement.

[0051] In this embodiment, a printing device is also provided, which includes the above-mentioned paper collation mechanism. The printing device effectively realizes the rapid splitting of multiple printed documents by applying the above-mentioned paper collation mechanism, saves the time of subsequent manual splitting, and improves work efficiency.
