The invention is described in further detail below with reference to the following detailed description and accompanying drawings:
the first embodiment is as follows:
referring to fig. 1 and 2, a printer according to a first embodiment of the present invention includes a paper feeding path. The printer comprises a driving component configured on the paper feeding channel and a controller electrically connected with the driving component. The driving assembly is used for driving the medium 11 in the paper feeding channel to move. The driving assembly comprises at least two driving units configured on the paper feeding channel.
The controller comprises a memory and a processor configured to execute a computer program in the memory to implement the steps of:
s1, acquiring the position of the medium 11 moving in the paper path.
S2, the number of drive units clamped on the medium is judged according to the position of the medium 11 in the paper feeding channel.
And S3, acquiring corresponding paper feeding speed according to the number of the drive units clamped on the medium, and driving the medium to move in the paper feeding channel at the paper feeding speed. Wherein each number corresponds to a paper feed speed.
Specifically, the driving assembly comprises a rubber roller 14, a first paper pressing wheel 7 and a first paper guide wheel 6 which are configured on the paper feeding channel. The first platen wheel 7 and the first paper guide wheel 6 can be brought into pressure contact with each other to sandwich the medium 11. The first paper pressing wheel 7 is connected with a motor in a transmission way so as to drive the medium 11 to move in the paper feeding channel.
The printer further comprises a printing assembly 3 arranged in the paper path. The rubber roller 14 and the printing component 3 are mutually matched and can be pressed and abutted together, so that the printing component 3 can print and form images on the medium 11. And the rubber roller 14 is in transmission connection with a motor to rotate synchronously with the first paper pressing wheel 7, so that the medium 11 is driven to move in the printing channel.
It should be noted that, during the transmission of the driving component inside the printer, there is resistance. To prevent step loss (i.e., the controller sends a control signal to the stepper motor that is unable to rotate due to excessive resistance or that rotates at an angle less than the angle that the control signal requires to rotate). In the prior art, the motor is always kept running at a low speed. Therefore, the printer is inefficient in operation, and is rotated at a low speed, thereby easily causing resonance between printer components and generating a large amount of noise.
The inventor has found through extensive research that, in the absence of the medium 11, since the printing assembly 3 cannot rotate, sliding friction occurs between the rubber roller 14 and the printing assembly 3, so that a large resistance is generated, and when the driving speed is too high, step-out is likely to occur. Once the media 11 moves between the blanket 14 and the print assembly 3, the resistance is greatly reduced because of the low coefficient of friction between the media 11 and the scan assembly 4 and the rolling friction between the blanket 14 and the media 11.
Based on this finding, the inventors have detected the position of the medium by providing a sensor in the paper feed path. And the number of drive units clamped on the medium is determined from the position of the medium and a corresponding speed is set for each number. It is understood that a larger number of drive units clamping the medium corresponds to a faster paper advance speed. In other embodiments, a plurality of sensors are not provided, and a calculation is performed according to a driving signal of the driving assembly to determine the position of the medium, and the position of the medium can also be acquired.
Further, the inventors configured the paper feed path into a plurality of paper feed sections. Specifically, the plurality of paper feeding sections are at least two paper feeding sections, and each paper feeding section is provided with at least one driving unit. That is to say one drive unit for each sheet-feed segment. The number of drive units clamped to the medium is equal to the number of paper feed sections through which the medium passes. The greater the number of paper advance sections through which the medium passes, the faster the medium is driven to move.
It is understood that the at least two paper feeding segments include a first paper feeding segment a and a third paper feeding segment C, the printing assembly 3 is disposed in the first paper feeding segment a, and the first platen roller 7 and the first paper guide roller 6 are disposed in the third paper feeding segment C. When entering the printer, the medium 11 first enters the third feeding section C and then enters the first feeding section a. Namely, the paper passes through the third paper feeding section C, and then simultaneously passes through the third paper feeding section C and the first paper feeding section A.
Therefore, in the present invention, when the head of the medium moves to the first paper feeding section a, the medium passes through the third paper feeding section C and the first paper feeding section a at the same time, and the corresponding driving speed is greater than the speed when the head of the printing medium moves to the third paper feeding section C.
Referring to fig. 1 and fig. 2, on the basis of the above embodiment, in an alternative embodiment of the present invention, the printer is a print-and-scan all-in-one machine. Which includes not only the printing assembly 3 but also the scanning assembly 4. It will be appreciated that the scanning assembly 4 is disposed in the sheet path between the printing assembly 3 and the first guide wheel 6. The drive assembly further comprises a third paper guide wheel 16 arranged in the paper feed path. The third paper guide wheel 16 is in pressure contact with the scanning assembly 4 to clamp the medium 11, thereby enabling the scanning assembly 4 to clearly scan the image on the medium 11.
It is understood that the at least two paper feeding segments include a second paper feeding segment B, and the scanning assembly 4 is disposed on the second paper feeding segment B. Preferably, the second feeding segment B is located at the rear end of the first feeding segment a in the feeding direction of the medium 11.
It should be noted that the same relationship is established between the printing unit 3 and the blanket roller 14. When the medium 11 has not moved between the scanning assembly 4 and the third paper guide wheel 16, there is direct contact between the third paper guide wheel 16 and the scanning assembly 4. Since the scanning unit 4 cannot rotate, the third paper guide wheel 16 and the scanning unit 4 are in sliding friction, and the generated resistance is large. Therefore, in the present invention, when the head of the medium moves to the second sheet feeding section B, the medium passes through the third sheet feeding section C and the second sheet feeding section B. That is, when the head of the medium moves to the second sheet feeding section B, the medium passes through the third sheet feeding section C and the second sheet feeding section B at the same time, and the corresponding driving speed is greater than the speed when the head of the printing medium moves to the third sheet feeding section C.
That is, the driving speed corresponding to when the head portion of the printing medium moves to the first sheet feeding section a is greater than the driving speed corresponding to when the head portion of the printing medium moves to the second sheet feeding section B. The corresponding driving speed when the head of the printing medium moves to the second paper feeding segment B is greater than the driving speed when the head of the printing medium moves to the third paper feeding segment C.
And, because the rubber roll and printing assembly, and the paper guide wheel and scanning assembly are in sliding friction when there is no medium, frictional force is great. Therefore, when the printing medium is not clamped between the rubber roller and the printing assembly and between the paper guide wheel and the scanning assembly, the printing medium is driven at a lower speed, the printing assembly (especially a heating wire on the printing head) and the scanning assembly can be prevented from being damaged, and a large amount of heat generated by friction can be avoided.
In this embodiment, the third paper feeding segment C, the second paper feeding segment B and the first paper feeding segment a are connected in sequence. In other embodiments, other components may be disposed in the paper path, and the paper path may be divided into a greater number of paper path segments, so as to control the movement of the medium 11 in the paper path more precisely. For example, a cutter device 1 may be disposed at the paper outlet of the printer, and a paper feeding roller 2 may be disposed between the cutter device 1 and the printing component 3, where the paper feeding roller 2 and the surface of the internal components of the printer are in sliding friction when the medium 11 is not moved to the paper feeding roller 2. Therefore, the feed rollers 2 need to be allocated in one sheet feeding section. The number of the paper feeding sections and what parts are specifically arranged on the paper feeding sections are not specifically limited.
In particular, the faster and faster the media 11 is fed through the printer, the greater the efficiency of the printer. Moreover, because the printer runs at a high speed, the vibration generated in the printer is small, and the noise in the running process is greatly reduced. Has good practical significance.
It will be appreciated that the media 11 in the print path may not only be fed, but may also be retracted. The resistance inside the printer becomes smaller and smaller during feeding, and becomes larger and larger during retreating. Therefore, the print medium 11 still needs to move at the paper feeding speed corresponding to the paper feeding section during the backward movement process, so that the print medium 11 is driven without desynchronizing the printer.
As shown in fig. 1 and 2, on the basis of the above-mentioned embodiments, in an alternative embodiment of the present invention, the paper feeding path includes a common path 23 in which the printing unit 3 and the scanning unit 4 are installed, and a first path 9 and a second path 24 communicating with the common path 23. The first path 9 has a paper feed port 10 communicating with the outside of the printer. The second passage 24 communicates with the common passage 23 and the paper deck 12 of the printer. The first paper feeding section and the second paper feeding section are arranged on a common channel, and the third paper feeding section is arranged on the first channel. Specifically, in the present embodiment, the paths of the print medium 11 and the scan medium 11 are separated. The scanning medium 11 enters the first path 9 from the paper inlet 10 and then enters the common path 23 to be scanned. The print media 11 is a continuous roll of paper 22 stored in a paper magazine 12 and enters the common path for printing from a second path 24.
In other embodiments, the print medium 11 and the scan medium 11 may be fed using the same path. That is, only the paper inlet 10 and the first path 9 are provided, and the second path 24 and the paper bin 12 are not provided, so that the printing and scanning functions can be realized. The present invention is not particularly limited in this regard.
In this embodiment, the driving assembly further includes a second paper guide wheel 19 and a second paper pressing wheel 20 disposed on the second channel 24, and a driving member drivingly connected to the first paper guide wheel 6, the second paper guide wheel 19, the third paper guide wheel 16 and the rubber roller 14. Specifically, by providing the printing unit 3 and the scanning unit 4 in the common path 23 and providing the paper deck 12 for the printer, not only can the internal structure thereof be made more compact, but also the whole can be made more portable. In addition, the portable electric heating cooker can be carried about for use, and has good practical significance. And set up first passageway 9 and for the user scans scanning medium 11, expanded the function of printer greatly, satisfy user's more demands.
The paper feeding channels are set to different paper feeding sections, and corresponding paper feeding speeds are set for the paper feeding sections. The medium 11 is driven according to the paper feeding speed of the paper feeding section where the head of the medium 11 is positioned, so that the driving component can drive the medium 11 at the most appropriate speed without desynchronizing, the printing/scanning speed is improved, and the noise during printing/scanning is reduced.
As shown in fig. 1 and 2, in an alternative embodiment of the present invention, based on the above-mentioned embodiments, the printer includes sensors disposed at each of the paper feeding sections. The sensor is used to detect the position of the medium 11. Preferably, the sensor is used to detect the head position of the medium 11. Specifically, the printer is provided with a first sensor 8 between a first paper guide roller and a paper inlet 10; a second sensor 5 located between the first paper guide roller and the scanning unit 4; a third sensor 15 located between the scanning assembly 4 and the printing assembly 3; a fourth sensor 13 at the exit of the printer, and a fifth sensor 18 between the second paper guide wheel 19 and the scanning assembly 4.
Since the first channel 9 and the second channel 24 are both in communication with a common channel, and the common channel is provided with the scanning assembly 4 in close proximity to the communication. Therefore, the corresponding driving speeds are the same when the head of the medium moves between the second sensor 5 and the third sensor 15, or when the head of the medium moves to the paper feeding section between the fifth sensor 18 and the third sensor 15.
The driving speed of the driving assembly, i.e., the moving speed of the medium in the paper path, is controlled according to the number of driving units of the medium clamped in the paper path. It will be appreciated that different numbers, with different resistances, and therefore controlling the drive speed in accordance with the number, will ensure that the drive assembly will drive the media at the most appropriate speed without losing step, thereby increasing the print/scan speed and reducing noise during printing/scanning.
