In order to reduce the weight of the paper feeding unit, the rotating shaft 901 may be a hollow shaft, and the material of the rotating shaft may be a material with a low density, such as aluminum, magnesium aluminum alloy, and the like. It can be understood that the material of the rotating shaft 901 can be freely selected according to actual conditions.

The sheet feeder 10 has at least one sheet guide 400 provided between the sheet receiving end 100a and a first sheet feeding unit disposed near the sheet receiving end 100a, and an upper surface of the sheet guide 400 forms a path for transporting the sheet.

The number of the paper guide mechanisms 400 between the paper receiving end 100a and the first paper feeding unit disposed near the paper receiving end 100a may be 1, or 2 or more. Illustratively, the number of the paper guide mechanisms 400 between the paper receiving end 100a and the first paper feeding unit disposed near the paper receiving end 100a is 2.

In some embodiments, at least one paper guide 400 may be disposed between every two paper feeding units. For example, the number of the paper guide mechanisms 400 provided between every two paper feed units may be 2. Thus, when the paper moves from one paper feeding unit to the next paper feeding unit, even if the paper hangs down due to gravity, the hanging end can move to the paper twisting wheel 300 of the next paper feeding unit through the guidance of the paper guide mechanism 400, thereby avoiding the paper from hanging down and falling to the paper twisting wheel 400 to cause paper jam.

And the control module is used for controlling the start and stop of the power component 500. The control module can control the power component 500 to be in a working state all the time; the start and stop of the power unit 500 may also be controlled based on the received signal. In some embodiments, the control module can be in communication connection with a host computer which is connected with the printer; when the printer starts to work, which may be considered that there will be paper entering the paper feeder 10, the printer or an upper computer connected to the printer, a signal for starting to work may be sent to the control module, and the control module controls the power unit 500 to start to work after receiving the signal for starting to work. Thus, the paper feeder 10 can start to work only when paper enters, so that the electric energy can be saved, and the energy consumption can be reduced.

In some embodiments, the paper feeder further comprises a sensor 700, the sensor 700 being disposed adjacent to the paper receiving end of the substrate 100, the sensor 700 being fixed to the substrate 100 or the stand 200; the sensor 700 is electrically connected with the control module; when the sensor 700 detects a sheet, the control module receives a detection signal from the sensor 700, controls the power unit 500 to operate, outputs a driving force to the transmission mechanism, and drives the pickup roller 300 to rotate, so as to transmit the sheet on the feeder 10.

The sensor 700 for detecting whether or not a sheet enters the sheet feeder 10 is provided at a position close to the sheet receiving end 100a, and may be provided on the surface of the substrate 100 or on the stand 200. The sensor 700 may be an infrared sensor, a micro switch, or other common sensors. Illustratively, as shown in fig. 2, the sensor 700 is an infrared sensor and is disposed on the stand 200.

When the sensor 700 detects a paper sheet, the paper sheet enters the paper feeder 10, and the control module receives a detection signal of the sensor 700, controls the power unit 500 to operate, and drives the pickup roller 300 to rotate through the transmission mechanism. The rotation of the pickup roller 300 can drive the paper thereon to move forward. A plurality of paper feeding units are arranged on the substrate 100 along the paper conveying direction a, and paper is conveyed from the paper receiving end 100a to the tail end 100b of the substrate 100 by the cooperation of the paper feeding wheels 300 on the paper feeding units, so as to complete paper feeding.

By providing the sensor 700, it is detected whether or not a sheet is fed to the sheet feeder 10, and the power unit 500 starts to operate only when a sheet is detected. Thus, the paper feeder 10 can start to work only when paper enters, so that the electric energy can be saved, and the energy consumption can be reduced. Particularly, by providing the infrared sensor, the paper feeder 10 does not need to be involved in the paper discharging process of the printer, and thus paper discharging of the printer is not hindered. Moreover, the whole paper feeder 10 can be integrated into a whole, does not need to be in communication connection with a printer or an upper computer, does not need to change the printer, and is simple and easy to install and control.

In order to further reduce the power consumption, the control module may further set an end delay time, the sensor 700 may transmit an end signal when the sensor 700 transitions from a state in which the paper can be detected to a state in which the paper cannot be detected, the control module may start timing when receiving the end signal, and the power unit 500 may be controlled to stop operating after the end delay time elapses. The delay time may be determined according to the distance between the sensor 700 and the end 100b of the substrate 100, the rotation speed and the diameter of the pickup roller 300, or may be set to a larger preset value, as long as it can be ensured that the last sheet detected by the sensor 700 can be completely transported to the end position of the substrate 100. It is understood that in some embodiments, the paper feeder 10 is not provided with the sensor 700, but rather has the control module connected to the printer or host computer. When the printer prints the last sheet or the upper computer sends the file to be printed, the printer can send an end signal, the control module can still set the end delay time, and the power component 500 is controlled to stop working according to the mode.

The control module is electrically connected with the sensor 700 and the power component 500. When there are multiple power components 500, the power components 500 may be connected to the control module separately, or connected in series and then connected to the control module.

In some embodiments, the paper feeder may further include a power module for providing power to the control module, the sensor 700, and the power unit 500. The power module can be a battery or a power adapter which receives mains supply input from outside and converts the mains supply into corresponding driving current.
