Embodiment 1
[0051] An embodiment of the present invention, such as figure 1 As shown, the present invention provides a paper jam detection system for a cash register printer, which includes a printing paper bin, an auxiliary roller 1 , a rotation detection module 2 and a processor 3 .
[0052] The auxiliary roller 1 is arranged in the printing paper compartment, and is used for assisting paper feeding during printing. Specifically, the auxiliary roller 1 can guide and support the movement of the paper, the rotation speed of the auxiliary roller 1 is equal to the moving speed of the paper, and the rotation speed of the auxiliary roller 1 is constant when the printer is printing.
[0053] The rotation detection module 2 is connected with the auxiliary roller 1, and is used for collecting the rotation data of the auxiliary roller 1 when the printer is printing.
[0054] The processor 3 is connected with the rotation detection module 2, and is used for judging whether the cash register print...
Embodiment 2
[0058] An embodiment of the present invention, such as figure 2 As shown, on the basis of Embodiment 1, the rotation detection module 2 includes a magnet and a magnetic sensor.
[0059] The magnet is arranged on the auxiliary roller 1, and the magnetic sensor is arranged on the printing paper bin opposite to the auxiliary roller 1, for when the auxiliary roller 1 rotates, the magnetic field generated by the cutting magnet triggers an electromagnetic response; or, the magnetic sensor is arranged On the auxiliary roller 1, the magnet is arranged on the printing paper compartment opposite to the auxiliary roller 1; when the auxiliary roller 1 drives the magnetic sensor to rotate, the magnetic field generated by the magnetic sensor cutting the magnet triggers an electromagnetic response.
[0060] The processor determines whether the cash register printer has jammed paper based on the electromagnetic response.
[0061] Preferably, the magnet is a non-circular magnet, and the magn...
Embodiment 3
[0067] An embodiment of the present invention, such as image 3 As shown, on the basis of Embodiment 1, the rotation detection module 2 includes an angular velocity sensor.
[0068] The angular velocity sensor is fixed in the auxiliary roller 1 for collecting the angular velocity data of the auxiliary roller 1 .
[0069] The processor 3 determines whether the cash register printer is jammed according to the angular velocity change rate of the auxiliary roller 1 during printing.
[0070] Specifically, in actual implementation, an angular velocity sensor can also be provided in the auxiliary roller 1, and the angular velocity sensor can collect the angular velocity data of the auxiliary roller 1, so that when the cash register printer prints, along with the rotation of the auxiliary roller 1, the angular velocity sensor It can also rotate accordingly, and because the speed of paper output is basically constant when the cashier printer is printing, the rotation speed of the auxi...
