[0002] The paper drive unit of a digital printer is a key mechanical system inside the printer responsible for feeding paper. It ensures that the paper enters the printing area along the correct path, speed, and positioning to complete the printing process. This unit typically consists of components such as feed rollers (for gripping the paper) and a conveyor belt / gear set (for transporting the paper). Its core design goal is to achieve stable and reliable paper feeding and reduce paper jams.

[0003] For example, Chinese patent disclosure: A novel paper driving structure unit, application number: CN201910535797.8, includes a mechanism base, a driven wheel assembly, pressure springs, and a driving wheel assembly. The left and right side walls of the mechanism base are provided with driven wheel bushing grooves and driving wheel bushing grooves. The driven wheel assembly is installed in the driven wheel bushing grooves on both sides, and the driving wheel assembly is installed in the driving wheel bushing grooves on both sides.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 and Figure 2As shown, a paper driving device for a digital printer includes a base 1, on which a paper placement slot 2 and a first groove 3 are provided. A first electric push rod 4 and a second electric push rod 5 are respectively provided on both sides of the first groove 3. A cleaning component 6 is fixedly provided on the first electric push rod 4. A lifting block 7 is fixedly provided on the second electric push rod 5. A motor 8 is fixedly installed on the lifting block 7. A rotating column 9 is provided on the motor 8. A paper feeding roller 10 is provided at one end of the rotating column 9. A second groove 11 is provided directly below the lifting block 7. A conveyor belt 12 is provided on one side of the paper placement slot 2.

[0020] like Figure 3 As shown, in another embodiment of the present invention, the cleaning component 6 includes a component base 601, with through grooves 602 on both sides of the component base 601, and a third groove 603 between the two through grooves 602. A plurality of cleaning brushes 604 are fixedly installed in the third groove 603. A first air supply groove 605 is provided on one side of the inner wall of the component base 601, and a second air supply groove 606 and a plurality of third air supply grooves 607 are respectively provided on the inner walls on both sides of the first air supply groove 605.

[0021] An air pump 608 is fixedly installed on one side of the outer wall of the component base 601. An air delivery hose 609 is provided at the air outlet of the air pump 608, and the air delivery hose 609 is reserved with sufficient length.

[0022] When the paper feed roller 10 needs cleaning, the motor 8 rotates the paper feed roller 10 via the rotating column 9, and then moves the cleaning component 6 towards the paper feed roller 10 via the first electric push rod 4, so that the paper feed roller 10 is located in the third groove 603. The cleaning brush 604 in the third groove 603 cleans the paper feed roller 10, and at the same time, the air pump 608 sucks up the dust generated in the third groove 603 during cleaning. The dust in the third groove 603 passes through the third air supply channel 607, the first air supply channel 605, and the second air supply channel 606 into the air pump 608, and then the air pump 608 sends the dust into the air supply hose 609. Subsequently, the air supply hose 609 transports the dust in the air pump 608 to a designated location, reducing the amount of dust accumulated in the third groove 603, thereby extending the service life of the cleaning component 6 and preventing it from falling back onto the paper feed roller 10, thus avoiding secondary pollution.

[0023] The working principle of a digital printer paper drive device:

[0024] In use, the paper is first placed in the paper placement slot 2. Then, the motor 8 rotates the paper feeding roller 10 via the rotating column 9. Subsequently, the second electric push rod 5 moves the lifting block 7 downward. The lifting block 7, through the rotating column 9, drives the paper feeding roller 10 to move, so that the paper feeding roller 10 contacts the paper pile. The paper feeding roller 10 moves the paper at the top of the paper pile onto the conveyor belt 12, and then the conveyor belt 12 moves the paper to the designated location. When a lot of dust accumulates on the paper feeding roller 10, the motor 8 rotates the paper feeding roller 10 via the rotating column 9, and then the first electric push rod 4 moves the cleaning component 6 toward the paper feeding roller 10, so that the paper feeding roller 10 is located in the third groove. In step 603, the cleaning brush 604 in the third groove 603 is used to clean the paper feed roller 10. At the same time, the air pump 608 is used to suck up the dust generated in the third groove 603 during cleaning. The dust in the third groove 603 passes through the third air supply groove 607, the first air supply groove 605, and the second air supply groove 606 into the air pump 608. The air pump 608 then sends the dust into the air supply hose 609, and then the air supply hose 609 transports the dust in the air pump 608 to the designated location. This effectively cleans the dust on the paper feed roller 10, improves paper feeding reliability, reduces paper jams / slippage, and extends the service life of the paper feed roller.

[0025] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
