After the paper is discharged, the paper can smoothly fall into the paper receiving box 19. A pickup wheel driving shaft 5 is arranged near the paper inlet of the paper feeding channel. A pickup wheel 6 is arranged on the pickup wheel driving shaft 5. The pickup wheel 6 is located on the paper feeding tray 1, as shown in FIG. Figure 4 As shown, two pins 23 are arranged at one end of the pickup wheel driving shaft 5, and the two pins 23 are arranged on the circumferential surface of the pickup wheel driving shaft 5 in a centrally symmetrical manner. A synchronous wheel 4 is arranged on the outer side of the end of the pickup wheel driving shaft 5 provided with the pins 23, and two pins 24 are arranged on the side of the synchronous wheel 4 close to the pickup wheel driving shaft 5, and the two pins 24 are arranged in a centrally symmetrical manner with the center of the synchronous wheel as the center. The synchronous wheel 4 is connected to the paging wheel driving motor 3 through a synchronous belt, and the positions of the pins 23 and the pins 24 are alternate. When the synchronous wheel 4 rotates, the pins 24 will touch and resist the pins 23, and the pins 24 are used between the pickup wheel driving shaft 5 and the synchronous wheel 4 driven by the paging wheel driving motor 3 to move the pickup wheel driving shaft 5, thereby driving the pickup wheel 6 to move, as shown in FIG.

The width of the blank paper detection device 13 is ≤310mm, and the full-width detection of ordinary A3 / A4 paper can be realized. A red light source 20 is arranged below the upper surface glass of the blank paper detection device 13. When detecting the red ink printed by the red seal on the back of the paper, the red ink can filter the detection result of the red area under the irradiation of red light, so that the detection is more accurate.

[0029] Example 3

[0030] This embodiment provides a paging detection encoding device, based on the embodiment 1-2, such as Figure 7 As shown, the paper pressing wheel 8 is arranged on the paper pressing wheel shaft, and oil-free copper sleeves 9 are arranged at both ends of the paper pressing wheel shaft, and a paper pressing spring 10 is arranged on the oil-free copper sleeve 9. Both ends of the paper pressing spring 10 are fixed on the machine body, and the paper pressing spring 10 is in a bent and tightened state. The paper pressing spring 10 has a downward pressure on the paper pressing wheel 8, so that the paper pressing wheel 8 fits with the corresponding paper feeding wheel 7. The paper pressing spring 10 realizes the up and down floating of the paper pressing wheel 8, so as to pass through papers of different thicknesses, as thin as letterhead paper and invoice paper, as thick as archive cover and kraft paper.

[0031] The working process of the paging detection encoding device of the utility model is as follows:

[0032] Put the document to be printed and coded into the paper feed tray 1, the paper feed sensor 2 is triggered, and the various components in the paging detection and coding device of the utility model start to run through the PLC control, and the paging wheel drive motor 3 starts to move, driving the synchronous wheel 4 to rotate. When the synchronous wheel 4 rotates, the two pins 24 on the inner side will contact the pin 23 at one end of the paper pickup wheel drive shaft 5, thereby driving the paper pickup wheel drive shaft 5 to rotate, and driving the paper pickup wheel 6 in the middle of the paper pickup wheel drive shaft 5 to rotate for paging.

[0033] When the paper enters the paper feed roller 7 and the pressure roller 8 under the friction of the pickup roller 6, the paper feeding speed of the paper feed roller 7 is greater than the paper feeding speed of the pickup roller 6 under the drive of the paper feeding motor 11. At this time, the paper will accelerate and move. When accelerating, it will give the pickup roller 6 a reverse force. At this time, the pickup roller 6 will accelerate and rotate at the paper feeding speed. The pickup roller driving shaft 5 on the pickup roller 6 accelerates to rotate, so that the pin 23 at one end of the pickup roller driving shaft 5 is no longer in contact with the two pins 24 on the inner side of the synchronous wheel 4 until the tail of this page of paper passes through the pickup roller 6; at this time, when the synchronous wheel 4 continues to rotate, the two pins 24 on the inner side of the synchronous wheel 4 do not contact with the pin 23 of the pickup roller driving shaft 5 until the two pins 24 on the inner side of the synchronous wheel 4 contact with the pin 23 at the right end of the pickup roller driving shaft 5. The pickup roller driving shaft 5 will rotate, drive the pickup roller 6 to rotate, and feed the next page of paper. In the continuous paper feeding process, it can be avoided that the paper enters together.

[0034] When the paper enters the detection position of the detection sensor 12, the detection sensor 12 is triggered, and the blank paper detection device 13 starts working to detect whether the paper is a blank page. The white elastic paper pressing piece 14 on the blank paper detection device 13 is inclined at an angle to the glass on the upper surface of the blank paper detection device 13, so that the paper passes close to the focus of the blank paper detection device 13. When the tail of the paper passes the detection sensor 12, the blank paper detection device 13 sends the detection result to the printing device.

[0035] When the paper moves to the print sensor 15, the front printing device 16 and the back printing device 17 print the printed content (page number) to the specified position of the paper under the delay control of the print sensor 15. When the paper passes through the paper output wheel, the upper end of the back paper guide 18 is bent in the paper output direction, which will make the paper turn and enter the paper receiving box 19. When the paper in the paper feed tray 1 is finished, the paper feed sensor 2 will no longer be triggered. The paper feed sensor 2 sets a delay time until the last piece of paper passes through the paper output wheel. At this time, the equipment will stop running, and the single file is printed.

[0036] From the above content, it can be seen that the paging detection encoding device of the utility model has the following advantages compared with the prior art:

[0037] 1) High coding efficiency: ≥210 pages per minute, replacing manual coding;

[0038] 2) Simple operation: One-touch operation, just put the document into the paper feed tray and press the run button, no manual intervention is required throughout the process.

[0039] 3) Wide adaptability: A spring is installed at the rotating shaft of the paper pressing wheel, and the paper pressing wheel can float up and down to reduce noise. The paper feeding wheel is made of soft rubber material, which not only reduces noise but also increases the paper gripping force; it can be used to pass papers of different thicknesses, such as thinner letterhead paper, A4 paper with bills, and thicker cover paper. The paper feeding channel width is 360mm, which can pass A4, A3, B5 and other papers.

[0040] 4) High paging accuracy: The pickup wheel transmission shaft and the synchronous wheel driven by the motor adopt a non-rigid connection, so that the pickup wheel transmission shaft is driven to operate. This solves the problem of continuous pages in traditional paging.

[0041] 5) High recognition accuracy: The width of the detection device is ≤310mm, which can realize full-width recognition of A3 / A4 paper. It solves the problem of blind spots in visual camera detection. A red light source is set in the detection device to solve the problem of false detection due to the penetration of the red seal to the back.

[0042] 6) Safe and reliable: All driving motors and components of the utility model adopt 24V DC, which is relatively safe. And all motors adopt stepper motors, which have stable operation, high detection accuracy and accurate encoding position.
