[0055] In addition, in order to better illustrate the present application, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0056] A printer is a device that converts digital information in a computer or other electronic device into a physical document. Its basic working principle is to control the print head or laser through signal processing, and use ink or toner to form characters or images on the transmitted paper. According to the imaging principle and printing method, printers are mainly divided into the following categories: dot matrix printers, inkjet printers, laser printers, 3D printers, etc. Preferably, the printing mechanism in this application is applied to inkjet printers. Among them, an inkjet printer is a printing device that forms text or images on a printing medium such as paper by spraying ink. The working principle of an inkjet printer is mainly based on single-chip microcomputer control. When the printing paper passes through the inkjet head, the main control circuit, under the drive of the printing signal, uses the inkjet technology corresponding to inkjet printing, for example, thermal bubble inkjet technology, to spray ink onto the printing paper at a very fast speed, thereby realizing inkjet printing.

[0057] Figure 1 FIG. 1 is a structural block diagram of a printing mechanism according to an exemplary embodiment. Figure 1 As shown, it may include a printing module and a printing drive module. The printing module includes a rotating frame 2, on which an inkjet structure is arranged.

[0058] In one possible implementation, the inkjet structure may include a material box 1 and a fixing portion 3 for fixing the material box 1. The fixing portion 3 and the material box 1 are detachably connected. The material box 1 is a component in the printing mechanism for storing and supplying ink or toner required for printing. The material box 1 may refer to an ink cartridge, that is, a component in the inkjet printing mechanism for storing printing ink, which is not limited in this application. Ink cartridges can be divided into black ink cartridges or color ink cartridges according to color, and black ink cartridges are mainly used to print black text and images. Color ink cartridges can contain inks of different colors, such as cyan, magenta, yellow, etc., which are used to print color graphics and photos to meet richer printing needs.

[0059] The cartridge 1 of the printing mechanism can use thermal bubble inkjet technology. Inside the nozzle of the cartridge 1, that is, each nozzle is connected to a micro heating resistor. When current passes through this resistor, it will quickly heat up to a very high temperature, usually 300°C. At this time, the heating resistor causes the ink in contact to evaporate instantly, forming a bubble. This bubble expands rapidly, pushing the surrounding ink toward the nozzle. As the bubble expands, it pushes a small drop of ink, usually a few picoliters in volume, out of the nozzle and sprays it onto the printed paper. The bubble then cools and bursts, causing negative pressure in the nozzle, attracting new ink to fill the nozzle in preparation for the next spray.

[0060] The material box 1 of the printing mechanism can also adopt piezoelectric inkjet technology. A nozzle drive unit is provided on the material box 1, and the nozzle drive unit is connected to the control module. The control module sends an electrical signal to the nozzle drive unit according to the dot matrix data. These electrical signals can accurately control the time for each nozzle on the nozzle in the material box 1 to spray ink droplets. The nozzle drive unit is provided with one or more piezoelectric crystals, which are connected to the nozzles and can be set to correspond to one piezoelectric crystal for each nozzle. After the control module sends an electrical signal to the piezoelectric crystal, the piezoelectric crystal will deform, and then squeeze the ink in the ink chamber to spray out from the nozzle, and at an extremely high speed, for example, thousands of drops of ink per second are hit on the paper to form text or patterns. The present application does not limit the printing method corresponding to the material box 1, and the specific method can be determined according to actual conditions.

[0061] The inkjet structure can be provided with a corresponding fixing part 3 according to different fixing methods. For example, the fixing part 3 can be provided as a magnetic fixing part, and one or more magnetic materials are provided on the fixing part 3 and the material box 1, and the material box 1 is fixedly adsorbed on the fixing part 3 by the magnetic attraction of the magnetic material. Among them, the magnetic material is provided on the inner wall of the fixing part 3 and the outer wall of the material box 1, and the position of the magnetic material provided on the fixing part 3 corresponds to that of the magnetic material provided on the material box 1. The present application does not limit the number and type of magnetic materials.

[0062] The fixing part 3 can also be set as a slide rail type fixing part, and a slide rail is set on the inner wall of the fixing part 3. After the material box 1 slides to the fixing part 3 through the slide rail, it is fixed by the locking device set on the fixing part 3. The fixing part 3 can also be provided with a snap-on fixing part, that is, a slot, and the material box 1 can be snapped on the fixing part 3 by pressing or the like. The present application does not limit the specific form of the fixing part 3. Preferably, the present application can use a magnetic fixing part to fix the material box 1. Such a setting can make the structural installation simpler and facilitate the user to install and disassemble.

[0063] In another possible implementation, the inkjet structure includes an ink storage device, and the ink storage device is integrally arranged with the rotating frame 2. The present application can directly integrate the ink storage device on the rotating frame 2. Specifically, it can be designed as an integral unit through injection molding, die casting and other processes, which is not limited in the present application. An ink storage port can be provided above the ink storage device, and the user can refill ink into the ink storage device through the ink storage port. The integrated arrangement of the ink storage device can reduce the number of independent components, making the overall structure more compact and simplified, which helps to reduce manufacturing costs, and can also reduce assembly time and the complexity of the printing mechanism. The present application does not limit the arrangement of the nozzles on the inkjet structure and the number of nozzles.

[0064] The printing drive module includes a pivot and a printing drive device. The printing mechanism may also include a support plate 9. The pivot may be arranged on the support plate 9, and the support plate 9 may be a base of the printing mechanism, and the present application does not limit the support plate 9. A rotating hole is arranged on the rotating frame 2, and the rotating frame 2 may be sleeved on the pivot through the rotating hole, and the rotating frame 2 may also be arranged integrally with the pivot, and the present application does not limit this. Furthermore, the printing drive device drives the rotating frame 2 to rotate and swing around the pivot, and at this time, while the rotating frame 2 rotates and swings, the printing module performs inkjet printing.

[0065] In one possible implementation, the printing drive device may include a driving motor 6; the driving motor transmission shaft 5 corresponding to the driving motor 6 may be coaxially arranged with the mobile phone, and accordingly, the driving motor 6 is directly connected to the rotating frame 2, and then the driving motor 6 directly drives the rotating frame 2 to rotate and swing around the pivot. This method not only simplifies the mechanical structure, but also improves the response speed and control accuracy of the system.

[0066] The working principle of the drive motor 6 is to convert electrical energy into mechanical energy by receiving a signal from the main control board 14, thereby driving the rotating frame 2 to swing back and forth around the pivot. Among them, the types of the drive motor 6 may include the following: a linear motor is a motor that generates force through an electromagnetic field and moves linearly. When current passes through the coil of the motor, a magnetic field is generated, and this magnetic field interacts with the permanent magnet in the motor, thereby performing linear motion, causing the print head to slide on the print medium and directly output text or images.

[0067] The stepper motor controls the rotation angle of the motor by receiving a pulse signal. Each time a pulse signal is received, the stepper motor will select a fixed angle. The stepper motor usually has multiple poles and coils, and the rotation direction of the motor is controlled by changing the direction of the current in the coil.

[0068] The servo motor achieves precise position and speed control through a closed-loop control system. The servo motor is usually equipped with a feedback device such as an encoder or a Hall element to monitor the position and speed of the motor and feed this information back to the main control board 14. The main control board 14 adjusts the current and voltage of the motor according to the feedback information to maintain the stable operation of the motor. The present application does not limit the type of the drive motor 6, which can be determined according to actual conditions.

[0069] In a possible implementation, the printing drive module further includes a transmission assembly; the transmission assembly and the driving motor 6 can be mounted on the support plate 9. A printing rotating gear 8 is provided at one end of the rotating frame 2; the transmission assembly and the printing rotating gear 8 can be in the same plane, the transmission assembly is meshed with the printing rotating gear 8, and the transmission assembly is also meshed with the driving motor 6. Further, the driving motor 6 drives the printing rotating gear 8 to rotate by driving the transmission assembly, thereby driving the rotating frame 2 corresponding to the printing rotating gear 8 to rotate and swing around the pivot.

[0070] In a possible implementation, the transmission assembly may include an input gear 4 and an output gear 7, and the present application does not limit the number of the input gear 4 and the output gear 7. The rotating frame 2, the input gear 4 and the output gear 7 may all be arranged on a support plate 9, and an input pivot corresponding to the input gear 4 and an output pivot corresponding to the output gear 7 may also be arranged on the support plate 9. The input gear 4 is sleeved on the input pivot, and the output gear 7 is sleeved on the output pivot. The drive motor transmission shaft 5 may be coaxially arranged with the input pivot, and the drive motor transmission shaft 5 may also be arranged to mesh with the input gear 4.

[0071] When the driving motor transmission shaft 5 and the input pivot are coaxially arranged, the output gear 7 is respectively meshed with the input gear 4 and the printing rotating gear 8, and then the driving motor 6 directly drives the input gear 4, thereby driving the output gear 7 and the printing rotating gear 8 to rotate.

[0072] When the drive motor transmission shaft 5 is meshed with the input gear 4, the input gear 4 is also meshed with the output gear 7, and the output gear 7 is meshed with the printing rotating gear 8. Furthermore, when the drive motor 6 is driven, the input gear 4, the output gear 7 and the printing rotating gear 8 are driven to rotate in sequence, so that the rotating frame 2 is rotated and swung around the pivot.

[0073] In another possible implementation, the transmission component can also be configured as a transmission belt. In the case where the transmission component is a transmission belt, one end of the transmission belt can be sleeved on the print rotating gear 8, and the other end of the transmission belt can be sleeved on the drive motor 6, that is, the transmission belt is rotatably connected to the drive motor 6 and the print rotating gear 8 respectively. Further, the drive motor 6 can drive the transmission belt, thereby driving the print rotating gear 8 at the other end of the transmission belt to rotate.

[0074] In another possible implementation, the transmission component can also be configured as a rack. When the transmission component is a linear rack, the print rotating gear 8 and the drive motor transmission shaft 5 can be arranged on the same straight line, and then the rack can be respectively engaged with the print rotating gear 8 and the drive motor 6. When the drive motor 6 is driven, the rack is driven to move, thereby driving the print rotating gear 8 to rotate.

[0075] The rack can also be set to an arc shape, and accordingly, the rack is meshed with the print rotating gear 8 and the drive motor 6 respectively. The present application does not limit the shape of the rack, and the corresponding rack can be set according to the positional relationship between the print rotating gear 8 and the drive motor 6. Similarly, the drive motor 6 drives the rack to move, thereby driving the print rotating gear 8 to rotate, so that the rotating frame 2 rotates and swings around the pivot. In the case where the print driving device is the drive motor 6, the present application does not limit the type of transmission component and the transmission mode, which can be determined according to actual conditions.

[0076] In a possible implementation, the print drive device can also be configured as an electromagnetic device. The main control board 14 of the printing mechanism may include a current control unit. The electromagnetic device is mainly a component used to generate a magnetic field, and the rotation and swing of the rotating frame 2 are achieved through the force of the magnetic field. The magnetic field has sufficient magnetic force to drive the rotating frame 2 to rotate and swing around the pivot, wherein corresponding magnetic materials are also provided on the rotating frame 2 to form a magnetic field with the electromagnetic device, thereby rotating and swinging. The print drive device is configured as an electromagnetic device, that is, unlike traditional mechanical drives or other types of drive methods, the electromagnetic device uses electromagnetic principles to achieve its driving function.

[0077] The current control unit is connected to the electromagnetic device, and its main function is to supply power to the electromagnetic device and control the operation of the electromagnetic device. Specifically, the current control unit controls the opening and closing of the electromagnetic device, and can adjust the current supplied to the electromagnetic device, thereby changing the magnetic field strength, so that the rotation and swing of the rotating frame 2 can be precisely controlled.

[0078] Figure 2 FIG. 1 is a structural diagram of an electromagnetic device according to an exemplary embodiment. Figure 2As shown, the electromagnetic device may include two groups of independent electromagnets, namely, a first electromagnet 19 and a second electromagnet 20. The first electromagnet 19 and the second electromagnet 20 are both arranged on both sides of the rotation and swinging direction of the rotating frame 2, and may also be arranged on the support plate 9. While the rotating frame 2 rotates and swings, it will alternately approach or move away from the first electromagnet 19 and the second electromagnet 20. For example, the first electromagnet 19 is arranged on the left side of the rotating frame 2, and the second electromagnet 20 is arranged on the right side of the rotating frame 2. The present application does not limit the positions of the first electromagnet 19 and the second electromagnet 20.

[0079] The first electromagnet 19 and the second electromagnet 20 affect the swing of the rotating frame 2 by generating their own magnetic fields. Since they are located on both sides of the motion path of the rotating frame 2, the motion of the rotating frame 2 can be precisely controlled by changing the strength and direction of their own magnetic fields. The current control unit provides current to the first electromagnet 19 or the second electromagnet 20 respectively. When the current control unit provides current to the first electromagnet 19, the first electromagnet 19 will generate a magnetic field, thereby attracting the rotating frame 2 to move to the left. When the rotating frame 2 rotates to the left starting position, that is, the nozzle in the printing mechanism sprays ink to the leftmost reference position, the current control unit stops supplying power to the first electromagnet 19, and at the same time, supplies current to the second electromagnet 20. At this time, the rotating frame 2 moves from the left starting position to the right end position, that is, moves to the rightmost reference position where the nozzle in the printing mechanism sprays ink, thereby enabling the rotating frame 2 to move smoothly and controlled between the two electromagnets.

[0080] Figure 3 FIG. 1 is a structural diagram of another electromagnetic device according to an exemplary embodiment. Figure 3 As shown, the electromagnetic device may further include a third electromagnet 22 and an elastic member 21. The third electromagnet 22 may be arranged on one side of the rotating frame 2 in the direction of rotation and swing, the elastic member 21 may be arranged on the other side of the direction of rotation and swing, and one end of the elastic member 21 may be fixedly connected to the other side of the rotating frame 2. The elastic member 21 may be arranged as a spring or other forms of elastic material, which is not limited in the present application. In the printing mechanism, the main function of the elastic member 21 is to provide a restoring force for the rotating frame 2 after the third electromagnet 22 does not provide a magnetic field to the rotating frame 2, so as to ensure that the rotating frame 2 can be restored to the reference position, i.e., the starting position or the end position, without the action of the electromagnetic force.

[0081] Specifically, the third electromagnet 22 can be set at the right reference position of the rotating frame 2 in the rotation and swinging direction, one end of the elastic member 21 is connected to the rotating frame 2, and the other end is fixed at the left reference position of the rotating frame 2 in the rotation and swinging direction. When the printing mechanism starts to operate, the current control unit provides current to the third electromagnet 22, so that the third electromagnet 22 is activated, and a magnetic field is generated to attract the rotating frame 2 to move to the right reference position. After the rotating frame 2 moves to the right reference position, the current control unit stops providing current to the third electromagnet 22. At this time, the rotating frame 2 returns from the right reference position to the left reference position under the action of the elastic member, thereby realizing the rotation printing function of the printing mechanism.

[0082] Figure 4 is a structural diagram of a printing mechanism according to an exemplary embodiment. Figure 4 As shown, the main control board can be arranged above the rotating frame 2, and the present application does not limit the position of the main control board. The main control board 14 is the control center of the printing mechanism, which is mainly responsible for obtaining the printing information provided by the external device, and after analyzing the printing information, controls the internal printing module and the printing drive module to perform rotation printing.

[0083] The external device may be, but is not limited to, a smart phone, a desktop computer, a tablet computer, a laptop computer, a smart speaker, a digital assistant, an augmented reality (AR) / virtual reality (VR) device, a smart wearable device, and other electronic devices. Optionally, the operating system running on the electronic device may include, but is not limited to, Android, IOS, Linux, Windows, and the like.

[0084] The main control board 14 is also provided with a communication module, which may include a wired communication module for data transmission with external devices through physical data lines. Wired communication may include a universal serial bus USB (Universal SerialBus), a high-definition multimedia interface HDMI (High Definition Multimedia Interface), etc., which are used to connect the printing mechanism and the external device, so that the external device can transmit the printing information to the main control board 14 through a wired transmission method such as USB. The present application does not limit the wired communication method of the printing mechanism. The communication module may also include a wireless communication module, such as wireless local area network technology Wi-Fi (IEEE 802.11), Bluetooth Bluetooth, Zigbee (IEEE 802.15.4), NFC (NearField Communication), etc. The present application does not limit the wireless communication connection method.

[0085] The printing information may include data of the contents of the printed document, picture, etc., and the printing parameters set by the user, such as the number of copies to be printed, the printing quality, etc., which are not limited in this application. After the main control board 14 obtains the printing information from the external device, it immediately parses and processes the printing information, and converts the printing information into instructions that can be recognized and executed by the printing mechanism, that is, after the main control board 14 parses the printing information, it will generate the corresponding printing instructions. At the same time, after receiving the printing information transmitted by the external device, the main control board 14 will also convert the printing information into a dot matrix form, specifically, determine the position of the inkjet on the printing paper. Furthermore, the main control board 14 will send the printing instructions to each module in the printing mechanism, such as the printing module, the printing driver module, and the paper transmission module.

[0086] After the print driver module receives the print instruction sent by the main control board 14, the print driver device will drive the rotating frame 2 to swing back and forth around the pivot. At the same time, the print module will also receive the print instruction and perform precise rotation and inkjet when the rotating frame 2 swings back and forth.

[0087] In a possible implementation, the printing mechanism also includes at least one origin sensor 10. The origin sensor 10 refers to a sensor that can detect and determine the origin position of the movement of the rotating frame 2, that is, the reference position. In the printing mechanism, the origin sensor 10 can be set on the support plate 9, that is, on both sides of the rotation and swinging direction of the rotating frame 2. The present application does not limit the position of the origin sensor 10. Specifically, the origin sensor 10 can be set at the leftmost reference position of the rotatable printing module, that is, the left starting position, so that when the main control board 14 drives the printing module to rotate around the pivot for printing, when the printing module swings to the leftmost origin position, it can accurately swing in the opposite direction around the pivot, thereby ensuring the printing quality and the normal operation of the printing mechanism.

[0088] The origin sensor 10 may include multiple types. The origin sensor 10 provided in the printing mechanism of the present application may be provided as a photoelectric sensor, which determines the position of the rotating frame 2 by blocking or reflecting a light beam. The photoelectric sensor is composed of a transmitter and a receiver. The transmitter emits a light beam, and when the rotating frame 2 rotates to the origin position, that is, the starting position on the left or the end position on the right, the light beam is blocked or reflected by the rotating frame 2, and the receiver detects this change and generates a trigger signal.

[0089] The magnetic sensor determines the rotational position of the printing module by detecting a magnetic mark. The working principle of the magnetic sensor is to install a magnetic mark on the printing module or the path of the rotational swing of the printing module. When the magnetic sensor detects this mark, it will immediately generate a trigger signal. The mechanical switch detects the position of the printing module through physical contact, that is, a mechanical switch is installed at the origin position of the printing module. When the printing module rotates to the origin position, the printing module triggers the mechanical switch, and at this time, the mechanical switch generates a trigger signal. The present application does not limit the type of the origin sensor 10, which can be determined according to actual conditions.

[0090] The origin sensor 10 monitors the rotation position of the printing module in real time. When the printing module is detected to swing to the origin position, a trigger signal is automatically generated and transmitted to the main control board 14. After receiving the trigger signal sent by the carriage origin sensor 10, the main control board 14 will immediately control the drive motor 6 to reverse, that is, control the printing module to swing in the opposite direction around the pivot. This setting can make the printing mechanism run efficiently and stably.

[0091] In one example, an origin sensor 10 can be set in the printing mechanism, and the specific position can be set at the left reference position of the rotating frame 2 rotation and swing, that is, the leftmost starting position of the rotating frame 2 for rotation printing; it can also be set at the right reference position of the rotating frame 2 rotation and swing, that is, the rightmost end position of the rotating frame 2 for rotation printing.

[0092] In another example, the printing mechanism can also be provided with two origin sensors 10, which are respectively provided at the left reference position and the right reference position of the rotating frame 2 for rotation and swinging. The two origin sensors 10 can be used simultaneously. For example, when the printing mechanism starts to perform rotation printing, the printing drive device can drive the rotating frame 2 to rotate and swing. When the rotating frame 2 swings to the left reference position, it directly triggers the origin sensor 10 on the left side, thereby determining the left starting position of the rotating frame 2 for selective inkjet printing. At this time, the origin sensor 10 at the left reference position generates a trigger signal and sends it to the control module of the main control board. After the control module receives the trigger signal generated by the origin sensor 10 at the left reference position, it immediately controls the printing drive device to drive the rotating frame 2 to rotate and swing to the right. When the rotating frame 2 triggers the origin sensor 10 at the right reference position, a trigger signal is generated again, the control module receives the trigger signal, and controls the printing drive device to drive the rotating frame 2 to rotate and swing to the left, thereby bidirectionally controlling the rotation and swinging process of the rotating frame 2, and improving the printing accuracy of the printing mechanism.

[0093] In another possible implementation, two origin sensors 10 are provided, which are respectively provided at the left reference position and the right reference position of the rotating frame 2, that is, the origin positions on both sides of the rotating frame 2. The origin sensor 10 on one side of the rotating frame 2 performs normal monitoring work, and the other side is used as a backup origin sensor and is in a standby state. When the origin sensor 10 on one side fails, it is immediately started. The above working mode can improve the reliability and fault tolerance of the printing mechanism, and can also improve the printing efficiency of the printing mechanism.

[0094] After the main control board 14 receives the trigger signal sent by the origin sensor 10 at the starting position of the rotating frame 2, it immediately determines the end position of the rotating frame 2 corresponding to the starting position according to the trigger signal, and then calculates the distance and direction that the printing module needs to swing. Further, according to the distance and direction that the printing module needs to swing, the drive motor 6 is controlled to drive the rotating frame 2 to rotate forward and reverse between the starting position and the end position. Among them, forward rotation can be the printing module swinging from the starting position to the end position around the pivot, and reverse rotation can be the printing module swinging from the end position to the starting position around the pivot. The present application does not limit the starting position and the end position.

[0095] Figure 5 FIG. 1 is a schematic diagram showing a rotation angle of a printing module according to an exemplary embodiment. Figure 3 As shown, the printing module can swing left and right around the pivot, thereby realizing rotary inkjet. Exemplarily, the rotational swing angle of the printing module around the pivot can be set to 135°, that is, the angle from the left reference position of the rotating frame 2 to the right reference position of the rotating frame 2. The present application does not limit the rotation angle of the printing module, which can be determined according to actual conditions.

[0096] Figure 6 FIG. 1 is a structural diagram of a paper transport module according to an exemplary embodiment. Figure 4 As shown, the printing mechanism also includes a paper transmission module, wherein the paper transmission module includes a paper driving device 13 and a paper transmission assembly. The paper transmission assembly includes a paper transmission rod and a paper transmission connecting member. The paper transmission connecting member is meshedly connected with the paper driving device 13, and the paper transmission rod and the paper transmission connecting member are rotatably connected.

[0097] In a possible implementation, the paper transmission connection member may include a plurality of paper transmission gear combinations, that is, the plurality of paper transmission gears transmit power to the paper transmission rod by meshing. The paper driving device 13 may drive any one of the plurality of paper transmission gears to rotate, and then drive the paper transmission rod to rotate by meshing between the paper transmission gears.

[0098] In another possible implementation, the paper transmission connection member may include a paper transmission belt, that is, one end of the paper transmission belt is engaged with the paper transmission rod, and the other end is engaged with the paper driving device 13. The paper driving device 13 drives the paper transmission belt to rotate.

[0099] In another example, the paper transmission connection member may also include a paper transmission gear and a paper transmission belt combination, the paper driving device 13 drives the driving gear in the paper transmission gear to rotate, the driving gear in the paper transmission gear drives the driven gear in the paper transmission gear to rotate through the paper transmission belt, and then drives the paper transmission rod 15 to rotate. The present application does not limit the type of the paper transmission connection member.

[0100] The paper drive device 13 can be a stepper motor, which rotates by receiving a digital pulse signal. Each time a pulse is received, the motor rotates a fixed angle (step angle). The servo motor is equipped with an encoder or other type of feedback device, which can monitor the actual position of the motor in real time and adjust it as needed. The present application does not limit the type of the paper drive device 13.

[0101] In one possible implementation, the printing mechanism also includes a paper storage module. The paper storage module is used to store printed paper. When the printed paper is placed flat, a paper tray, i.e., a paper bin, can be provided at the bottom of the printing mechanism. An openable and closable cover is provided under the paper tray, and the cover can be made of a sturdy metal material or plastic to ensure the durability and stability of the cover. The user can manually open and close the cover to place the paper flat on the paper tray. The present application does not limit the capacity of the paper tray, and the specific number of printed papers stored can be determined according to actual conditions.

[0102] A paper feed may be provided on one side of the outside of the printing mechanism, and a switch module corresponding to the paper feed is also provided on the outside of the printing mechanism. When there is paper inside the printing mechanism, the paper feed is in a closed state, which can effectively prevent dust from entering the inside of the printing mechanism and keep the printed paper clean. When there is no paper inside the printing mechanism, the user can open the paper feed through the switch module. Then, the paper is pushed from the paper feed to the paper tray. Accordingly, the paper is placed in the paper storage module, that is, the accurate paper output position, through the paper limiting unit. After the user has placed the paper, the paper feed is further closed through the switch module. This application does not limit the structure for placing paper.

[0103] In another possible implementation, the paper storage module may include a paper roll holder for supporting a rotating paper roll. When the printing paper is a rotating paper roll, the paper roll holder may be disposed inside the printing mechanism, the rotating paper roll is sleeved on the rotating holder, and the rotating paper roll is connected to the paper transport module. When the printing mechanism starts printing, the rotating paper roll rotates and rolls, and is moved to the outside of the printing mechanism through the paper transport assembly.

[0104] In a possible implementation, the printing mechanism further includes a paper position sensor 17. The paper position sensor 17 is arranged at the paper outlet of the paper conveying module, that is, the front position of the paper transmission rod, and is used to detect the front end position of the paper to ensure that the paper can enter the printing area correctly and aligned for printing. After the external device sends the printing information to the main control board 14, the printing task starts at this time. After receiving the printing information, the main control board 14 will instruct the paper conveying module to perform the conveying process according to the preset printing settings. Under the action of the paper conveying module, the printing paper starts to move from the paper storage module to the printing area. Correspondingly, the main control board 14 instructs the paper position sensor 17 arranged at the paper outlet of the paper conveying module to start monitoring the paper outlet. When the paper is detected to appear at the paper outlet, the paper position sensor 17 immediately sends the paper position information to the main control board 14. After receiving the paper position information, the main control board 14 immediately sends a printing instruction to the printing module and the printing driver module, so that the printing mechanism can perform rotary inkjet printing on the printing paper.

[0105] The paper position sensor 17 can be a penetrating paper position sensor. The penetrating paper position sensor irradiates light onto the surface of the paper through components such as photodiodes and photosensitive diodes, and uses the penetration and reflection of light to monitor the tip position and size of the paper. The working principle of the penetrating paper position sensor is: light is irradiated from a light-transmitting component to the surface of the paper, and then passes through the paper and is directed to another photoelectric element. The tip position of the paper is determined by detecting the amount of light that is transmitted. The paper position sensor 17 can also be a reflective paper position sensor. The reflective paper sensor irradiates light onto the surface of the paper and uses the reflection of light to detect the tip position of the paper. The working principle of the reflective paper sensor is that after the light is irradiated to the surface of the paper, it is reflected back, and the intensity and time of the reflected light are detected by the photosensitive element to determine the tip position of the paper. This application does not limit the type of paper position sensor 17.

[0106] In a possible implementation, the printing mechanism further includes a nozzle scraper 12 and an ink-absorbing cotton 11. Among them, a scraper groove may be provided on the support plate 9 for fixing the nozzle scraper 12, so that the stability of the nozzle scraper 12 can be ensured, and the difficulty of installation and maintenance is reduced. The present application does not limit the shape and size of the nozzle scraper 12. Specifically, the nozzle scraper 12 is arranged on the outside of the origin sensor 10. For example, when the origin sensor 10 is arranged at the left origin position, the nozzle scraper 12 is arranged at the left position of the origin sensor 10. A plurality of nozzles are arranged under the inkjet structure of the rotating frame 2, and a plurality of small nozzles are provided on each nozzle. When the printing mechanism has not been used for a long time or has not been turned on, the nozzles under the inkjet structure may be dried up with ink, which is easy to be blocked, thereby affecting the printing quality. Furthermore, when the printing mechanism starts to be used, the main control board 14 will first control the drive motor 6 to drive the rotating frame 2 to rotate and swing to the position where the nozzle scraper 12 is located. Furthermore, the nozzle scraper 12 can scrape the nozzle at the bottom of the material box 1 to remove the ink clogged on the nozzle, so that in the subsequent printing process, the printing efficiency and printing accuracy can be improved. After the nozzle scraper 12 finishes scraping the ink, the ink will flow directly along the nozzle scraper 12 to the ink-absorbing cotton 11. This design can ensure the smooth discharge of the ink and avoid the accumulation and contamination of the ink inside the printing mechanism. Through the absorption effect of the ink-absorbing cotton 11, the entire printing mechanism can be kept clean and dry, thereby extending the service life of the mechanism and improving the printing quality.

[0107] In a possible implementation, the printing mechanism further includes a power module and an interface module. The power module is used to provide power to the internal components of the printing mechanism. For example, it is used to provide a stable power supply to components such as the main control board 14, the printing module, and the printing driver module. The power module is connected to the interface module, and the interface module is provided with a charging interface, which usually adopts interfaces such as USB and Type-C to ensure compatibility with various charging devices, which is not limited in this application. When the power module of the printing mechanism is insufficient, the user can insert the charging cable into the charging interface, and the battery module can be connected to an external charging device, such as a power bank or an external power supply, for charging. The present application can also set a wireless charging receiver inside the printing mechanism, which is connected to the power module. When the printing mechanism is insufficient, the user can place a dedicated wireless charging adapter at a designated position on the printing mechanism to start the wireless charging process. The power module in the printing mechanism can also be set as a replaceable battery, and the battery can be replaced in time when the power module is insufficient. The present application does not limit the way the power module is charged. The interface module can also include a communication module, which is connected to the main control board, and is used to obtain or receive printing information transmitted by an external device.

[0108] In the present application, the printing mechanism is set to rotary swing inkjet printing, so that the printing module can achieve large-scale printing in a smaller space, which can significantly reduce the overall volume of the printing device, making the structure of the printing mechanism more compact, which is conducive to integrating more functional modules in a limited space. Accordingly, the printing mechanism of the present application is integrated in a portable inkjet printing device, which can be convenient for users to carry with them, and the printing mechanism of the present application can be directly used for rotary inkjet printing in any scenario.

[0112] The printing module is used to receive a printing instruction, and when the rotating frame 2 rotates and swings, controls the inkjet structure in the printing module to perform inkjet printing according to the printing instruction.

[0113] Figure 8 FIG. 1 is a structural diagram of an imaging device according to an exemplary embodiment. Figure 8 As shown, it includes a camera module 18 and a printing mechanism. The camera module 18 is responsible for capturing static images, and the camera module 18 can be configured as a digital camera, a webcam or other types of image sensors, which are not limited in the present application.

[0114] The printing mechanism is connected to the camera module 18, and the printing mechanism can obtain the image captured by the camera module 18 and process the captured image, such as adjusting the brightness and contrast.
