Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a printing mode switching device and a printer including the same. Background Technology

[0002] A printer needs to coordinate and control multiple interrelated actions during the printing process, mainly including: paper picking up paper from the paper tray, paper feeding during printing, printhead carriage movement during printing, and maintenance such as cleaning and sealing the printhead.

[0003] Existing technology involves equipping the different actions described above with independent power sources, i.e., using multiple dedicated motors for driving. A typical design includes the following four motors:

[0004] The letter carrier motor: The letter carrier is connected to the guide rail, and the letter carrier motor drives the letter carrier to make reciprocating linear motion along the guide rail.

[0005] Paper feed motor: The paper feed motor is fixed to the other end of the guide rail and is used to precisely control the rotation of the paper feed roller during the printing process to advance the paper.

[0006] State-fixing motor: This motor does not directly participate in any of the above actions, but controls the extension and retraction of the mode telescopic component through the drive gear set. The mode telescopic component forms a mechanical limit on the swing arm of the swing switching component after the state is switched, so as to fix the state after the paper picking state or cleaning state is switched.

[0007] Paper feed / cleaning motor: This motor drives the rotation of the swing arm assembly, which includes a swing arm, a swing arm gear, and a rotating gear. The paper feed / cleaning motor drives the rotating gear to rotate, which in turn causes the swing arm to swing. The swing arm gear meshes with the rotating gear and is connected to the end of the swing arm, allowing it to swing along with the arm. The swing arm gear is connected to either the paper feed-related structure or the cleaning-related structure. When switching to the paper feed mode, the mode extension extends, stopping the swing arm from swinging, but the rotating gear rotates. The rotation of the rotating gear enables paper feeding or cleaning.

[0008] However, although the above design achieves the basic printing action by using multiple discrete motors, it still suffers from problems such as complex structure, low reliability, and high production cost. Utility Model Content

[0009] The technical problem to be solved by this utility model is to overcome the defects of existing printers, such as complex structure, low reliability and high production cost caused by the use of multiple discrete motors, and to provide a printing mode switching device and a printer including the same.

[0010] The present invention solves the above-mentioned technical problems through the following technical solution:

[0011] A printing mode switching device is characterized in that it includes a carriage drive mechanism, a mode telescopic component, a paper feed roller, a paper feed roller, a cleaning component, a swing switching component, a paper feed drive mechanism, and a transmission component. The paper feed drive mechanism is connected to the paper feed roller. One end of the transmission component is connected to the paper feed roller, and the other end of the transmission component is connected to the swing switching component and is used to drive the rotation of the swing switching component. The carriage drive mechanism abuts against the mode telescopic component and is used to drive the mode telescopic component to extend and retract, so that the mode telescopic component extends and the swing switching component abuts against either side of the mode telescopic component, or the mode telescopic component retracts and disconnects from the swing switching component.

[0012] When the swing switching member abuts against one side of the mode telescopic member, the swing switching member is connected to the paper pick-up roller and disconnected from the cleaning component, and the rotation of the swing switching member drives the movement of the paper pick-up roller.

[0013] When the swing switching member abuts against the other side of the mode telescopic member, the swing switching member is connected to the cleaning component and disconnected from the paper pick-up roller, and the rotation of the swing switching member drives the movement of the cleaning component.

[0014] In this solution, the aforementioned structural form is adopted. The paper feeding drive mechanism transmits power to the paper feeding roller, which on the one hand drives the paper feeding roller to rotate and propels the paper forward. On the other hand, since the paper feeding roller is connected to the transmission component, the transmission component transmits power from the paper feeding roller to the oscillating switching component, which in turn drives the oscillating switching component to rotate. This allows the paper feeding drive mechanism to not only drive the paper feeding roller to move, but also drive the oscillating switching component to rotate, switching between paper picking and cleaning states. This reduces the number of paper picking / cleaning motors used, lowers production costs, and features a simple structure and high reliability. The carriage drive mechanism can not only reciprocate along the guide rail, but also extend and retract along the carriage movement direction by abutting against the mode telescopic component. The mode telescopic component mechanically limits the oscillating switching component after the state switch, thus fixing the state after the state switch. Utilizing the movement of the carriage drive mechanism itself as the driving force reduces the number of state-fixing motors used, lowers production costs, and features a simple structure and high reliability.

[0015] Preferably, the printing mode switching device further includes a mounting bracket, and the mode telescopic component includes a stop rod, a trigger rod, and a telescopic seat. The telescopic seat is movably connected to the mounting bracket. One end of the stop rod is connected to the telescopic seat, and the other end of the stop rod extends outward along the moving direction of the carriage drive mechanism. One end of the trigger rod is connected to one side of the telescopic seat, and the other end of the trigger rod extends outward along the direction close to the carriage drive mechanism, so that the carriage drive mechanism abuts against the trigger rod.

[0016] In this solution, the above-mentioned structural form is adopted. When the carriage drive mechanism abuts against the mode telescopic component, the carriage drive mechanism acts on the trigger rod, causing the abutment rod of the mode telescopic component to move in extension and retraction with the mode telescopic component. The structure is simple, highly reliable, and adopts a fully mechanical structure, which reduces manufacturing costs.

[0017] Preferably, the mounting bracket has at least one slide rod, and the telescopic seat and / or the trigger rod have sliding holes. The slide rod is inserted into the sliding holes to move the telescopic seat and / or the trigger rod on the mounting bracket.

[0018] In this solution, the above-mentioned structural form is adopted. Through the synergistic effect of the telescopic component and the mounting frame, a unique and stable straight trajectory is provided for the movement of the telescopic seat, which has high precision and is simple to process and easy to produce.

[0019] Preferably, the printing mode switching device further includes an elastic element, the two ends of which abut against the side of the mounting bracket and the mode telescopic element facing away from the print head drive mechanism, respectively.

[0020] In this solution, the above-mentioned structure is adopted. The carriage drive mechanism abuts against the mode telescopic component, and the mode telescopic component performs telescopic movement. The elastic component also performs telescopic movement under the action of the mode telescopic component. The kinetic energy of the carriage drive mechanism is stored as elastic potential energy through the elastic component. When the carriage drive mechanism moves away from the mode telescopic component, the elastic potential energy of the elastic component is converted into kinetic energy and acts on the mode telescopic component, causing the mode telescopic component to abut against the limiting component and achieve automatic reset, thereby fixing the paper picking or cleaning state.

[0021] Preferably, both the swing switching component and the transmission component are connected to the mounting bracket, which has a through hole, through which the abutment rod passes and can extend and retract within the through hole.

[0022] In this solution, the above-mentioned structural form is adopted. By integrating the swing switching component, transmission component and mode telescopic component on the mounting frame, the structural connection is simple, the overall integrity is better, the assembly is convenient, and the reliability is high.

[0023] Preferably, the carriage drive mechanism includes a drive motor and a carriage, wherein the carriage has an outwardly protruding actuating portion at one end facing the mode telescopic member, and the drive motor is connected to the carriage and is used to drive the carriage to move in a direction close to the mode telescopic member, so that the actuating portion abuts against the mode telescopic member.

[0024] In this solution, the above-mentioned structure is adopted. By using the word carriage drive mechanism as the driving force, the trigger part moves with the word carriage toward the mode telescopic member and acts on the trigger rod of the mode telescopic member, so that the mode telescopic member performs telescopic movement. The structure is simple, reliable, and reduces production costs.

[0025] Preferably, the swing switching component includes a rotating gear, a swing arm body, a swing arm gear, a cleaning swing arm, and a cleaning gear. The transmission component is connected to the rotating gear and drives the rotation of the rotating gear. The swing arm body is connected to the rotating gear. The swing arm gear is connected to one end of the swing arm body and meshes with the rotating gear. The other end of the swing arm body abuts against the mode telescopic component. The two ends of the cleaning swing arm are respectively connected to the rotating gear and the cleaning gear and drive the swing of the cleaning gear, so that the cleaning gear is connected to or disconnected from the cleaning component. The cleaning gear is located between the mode telescopic component and the cleaning component, and meshes with the rotating gear. The rotating gear is driven to rotate by the paper feeding drive mechanism and switched to a paper picking state, a forward cleaning state, or a reverse cleaning state.

[0026] In the paper-feeding state, the swing arm body abuts against the side of the mode telescopic member facing the cleaning gear, and the swing arm gear is connected to the paper-feeding roller and disconnected from the cleaning component.

[0027] In the forward cleaning state, the swing arm body is located on the side of the mode telescopic member facing away from the cleaning gear. The swing arm gear is connected to the cleaning component and disconnected from the paper pick-up roller. The cleaning gear is disconnected from the cleaning component.

[0028] In the reverse cleaning state, the swing arm body abuts against the side of the mode telescopic member facing away from the cleaning gear. The swing arm gear is disconnected from both the cleaning component and the paper pick-up roller. The cleaning gear is connected to the cleaning component.

[0029] In the forward cleaning state, the rotation direction of the rotating gear is opposite to that in the reverse cleaning state.

[0030] In this solution, the above-mentioned structural form is adopted. By using the paper feeding drive mechanism as the power source, and cooperating with the swing switching component and the gear meshing with it, a system for switching the paper feeding roller and the cleaning component is formed. By changing the relative position of the swing switching component and the mode extension component, the paper feeding state, the forward cleaning state and the reverse cleaning state can be switched. This saves driving components to the maximum extent, achieves a high degree of functional integration, simplifies the overall structure, and improves the reliability of operation during the paper feeding or cleaning state.

[0031] Preferably, the swing arm body has an outwardly protruding limiting portion and an abutting limiting portion that abuts against the mode telescopic member at one end, the abutting limiting portion being located between the protruding limiting portion and the cleaning gear.

[0032] In this solution, the above-mentioned structural form is adopted. By setting the abutment limiting part between the protruding limiting part and the cleaning gear, the swing arm is prevented from crossing its working position by mechanical limiting. This eliminates the transmission risk caused by overshoot or inaccurate positioning, prevents the power transmission path from failing due to incomplete gear meshing, and ensures the reliability of the switching process.

[0033] Preferably, the transmission component includes a plurality of meshing transmission gears, with two of the transmission gears located at both ends meshing with the paper feed roller and the oscillating switching component, respectively.

[0034] In this solution, the above-mentioned structure is adopted. By meshing the two transmission gears at both ends of the transmission component with the first gear of the paper feed roller and the rotating gear of the swing switching component, the power of the paper feed drive mechanism is transmitted from the paper feed roller to the swing switching component through the transmission gear of the transmission component. This reduces the number of power sources used, lowers production costs, and provides a simple force transmission path with high reliability.

[0035] A printer characterized in that it includes a printing mode switching device as described above.

[0036] The positive and progressive effects of this utility model are as follows:

[0037] The paper feed drive mechanism transmits power to the paper feed roller, which on one hand drives the roller to rotate and propels the paper forward. On the other hand, since the paper feed roller is connected to the transmission component, the transmission component transmits power from the roller to the oscillating switching component, causing it to rotate. This allows the paper feed drive mechanism to not only move the roller but also rotate the oscillating switching component, switching between paper feeding and cleaning modes. This reduces the number of paper feeding / cleaning motors required, lowers production costs, and features a simple structure and high reliability. The carriage drive mechanism can not only reciprocate along the guide rail but also extend and retract along the carriage's direction of movement by abutting against the mode telescopic component. The mode telescopic component mechanically limits the oscillating switching component after the mode switch, fixing the state after the switch. Utilizing the carriage drive mechanism's own movement as the driving force reduces the number of state-fixing motors required, lowers production costs, and features a simple structure and high reliability.

[0090] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0091] like Figures 1 to 9 As shown, this embodiment discloses a printing mode switching device, which includes a carriage drive mechanism 1, a mode telescopic component 2, a paper feed roller 3, a paper feed roller 4, a cleaning component 5, a swing switching component 6, a paper feed drive mechanism 7, and a transmission component 8. The paper feed drive mechanism 7 is connected to the paper feed roller 4. One end of the transmission component 8 is connected to the paper feed roller 4, and the other end of the transmission component 8 is connected to the swing switching component 6 and is used to drive the rotation of the swing switching component 6. The carriage drive mechanism 1 abuts against the mode telescopic component 2 and is used to drive the mode telescopic component 2 to extend and retract, so that the mode telescopic component 2 extends and the swing switching component 6 abuts against either side of the mode telescopic component 2, or the mode telescopic component 2 retracts and disconnects from the swing switching component 6.

[0092] When the swing switching member 6 abuts against one side of the mode telescopic member 2, the swing switching member 6 is connected to the paper take-up roller 3 and disconnected from the cleaning member 5. The rotation of the swing switching member 6 drives the movement of the paper take-up roller 3.

[0093] When the swing switching component 6 abuts against the other side of the mode telescopic component 2, the swing switching component 6 is connected to the cleaning component 5 and disconnected from the paper take-up roller 3. The rotation of the swing switching component 6 drives the movement of the cleaning component 5.

[0094] Specifically, in this embodiment, the paper feed roller 4 includes a first gear 41 and a second gear 42. The paper feed drive mechanism 7 includes a second belt 72 and a second pulley 73. The second gear 42 is located at the end of the paper feed roller 4, and the first gear 41 is located inside the second gear 42 and is sleeved on the paper feed roller 4. The paper feed drive mechanism 7 drives the second pulley 73 to rotate via the second belt 72. The second belt 72 is connected to the second gear 42 of the paper feed roller 4, driving the paper feed roller 4 to rotate. One end of the transmission component 8 is connected to the first gear 41 of the paper feed roller 4, and the other end of the transmission component 8 is connected to... The oscillating switching element 6 is used to drive its rotation; the paper feeding drive mechanism 7 transmits power to the paper feeding roller 4, which can drive the paper feeding roller 4 to rotate and drive the paper forward. On the other hand, since the paper feeding roller 4 is connected to the transmission component 8, the transmission component 8 transmits power from the paper feeding roller 4 to the oscillating switching element 6 and drives the oscillating switching element 6 to rotate. This allows the paper feeding drive mechanism 7 to not only drive the paper feeding roller 4 to move, but also drive the oscillating switching element 6 to rotate, switching between paper picking or cleaning states. This reduces the number of paper picking / cleaning motors used, lowers production costs, and has a simple structure and high reliability.

[0095] Specifically, the carriage drive mechanism 1 of this embodiment includes a guide rail 15. The carriage 14 moves along the guide rail 15 toward the mode telescopic member 2 and abuts against the mode telescopic member 2, driving the mode telescopic member 2 to extend and retract along the moving direction of the carriage 14. After the mode telescopic member 2 extends, the swing switching member 6 abuts against either side of the mode telescopic member 2, or the mode telescopic member 2 retracts and disconnects from the swing switching member 6. When the swing switching member 6 abuts against one side of the mode telescopic member 2, the swing switching member 6 is connected to the gear of the paper take-up roller 3 and disconnected from the gear of the cleaning component 5. The rotation of the swing switching member 6 drives the movement of the paper take-up roller 3. When it is against the other side of the mode telescopic component 2, the swing switching component 6 is connected to the cleaning component 5 and disconnected from the paper pick-up roller 3. The rotation of the swing switching component 6 drives the movement of the cleaning component 5. The carriage drive mechanism 1 can not only move back and forth along the guide rail 15, but also move the mode telescopic component 2 along the moving direction of the carriage 14 by abutting against the mode telescopic component 2. The mode telescopic component 2 forms a mechanical limit on the swing switching component 6 after the state is switched, realizing the state fixation after the state is switched. The movement of the carriage drive mechanism 1 itself is used as the driving force, reducing the number of state-fixing motors used, reducing production costs, and the structure is simple and highly reliable.

[0096] The printing mode switching device also includes a mounting frame 9. The mode telescopic component 2 includes a stop rod 21, a trigger rod 24, and a telescopic seat 22. The telescopic seat 22 is movably connected to the mounting frame 9. One end of the stop rod 21 is connected to the telescopic seat 22, and the other end of the stop rod 21 extends outward along the moving direction of the print head drive mechanism 1. One end of the trigger rod 24 is connected to one side of the telescopic seat 22, and the other end of the trigger rod 24 extends outward along the direction close to the print head drive mechanism 1, so that the print head drive mechanism 1 abuts against the trigger rod 24.

[0097] Specifically, the printing mode switching device in this embodiment also includes a mounting frame 9. The mode telescopic component 2 includes a stop rod 21, a trigger rod 24, and a telescopic seat 22. The mode telescopic component 2 is disposed inside the mounting frame 9. The telescopic seat 22 is movably connected to the mounting frame 9. One end of the stop rod 21 is connected to the telescopic seat 22, and the other end of the stop rod 21 extends outward along the moving direction of the carriage drive mechanism 1. One end of the trigger rod 24 is connected to one side of the telescopic seat 22, and the other end of the trigger rod 24 extends outward along the direction close to the carriage drive mechanism 1. The mode telescopic component 2 is integrally formed. When the carriage drive mechanism 1 abuts against the mode telescopic component 2, the carriage drive mechanism 1 acts on the trigger rod 24, causing the stop rod 21 of the mode telescopic component 2 to telescopically move with the mode telescopic component 2. The structure is simple, the reliability is high, and the all-mechanical structure reduces manufacturing costs.

[0098] The mounting bracket 9 has at least one slide rod 91, and the telescopic seat 22 has a sliding hole 23. The slide rod 91 is inserted into the sliding hole 23 so that the telescopic seat 22 can move on the mounting bracket 9.

[0099] Specifically, the mounting frame 9 in this embodiment also includes two slide rods 91, and two corresponding slide holes 23 are opened on the telescopic seat 22. When the slide rods 91 are inserted into the corresponding slide holes 23, the telescopic seat 22 moves along the slide rods 91 on the mounting frame 9 under the action of the trolley drive mechanism 1. Through the coordinated action of the mode telescopic component 2 and the mounting frame 9, a unique and stable straight trajectory is provided for the movement of the telescopic seat 22, which has high precision and is simple to process and easy to produce.

[0100] The mounting bracket 9 has at least one slide rod 91, and the trigger rod 24 has a sliding hole 23. The slide rod 91 is inserted into the sliding hole 23 so that the trigger rod 24 can move on the mounting bracket 9.

[0101] Specifically, the mounting frame 9 in this embodiment also includes two slide rods 91, and two corresponding sliding holes 23 are opened on the trigger rod 24. When the slide rod 91 is inserted into the corresponding sliding hole 23, the trigger rod 24 moves along the slide rod 91 on the mounting frame 9 under the action of the trolley drive mechanism 1. Through the coordinated action of the mode telescopic member 2 and the mounting frame 9, a unique and stable straight trajectory is provided for the movement of the trigger rod 24, which has high precision and is simple to process and easy to produce.

[0102] The printing mode switching device also includes an elastic element 94, the two ends of which abut against the mounting bracket 9 and the mode telescopic element 2 on the side opposite to the carriage drive mechanism 1.

[0103] Specifically, the printing mode switching device in this embodiment further includes an elastic element 94, and the number of elastic elements 94 is one. The mounting frame 9 also includes a limiting element 92. The elastic element 94 is disposed on the slide rod 91 of the mounting frame 9. The two ends of the elastic element 94 abut against the mounting frame 9 and the side of the mode telescopic member 2 facing away from the carriage drive mechanism 1, respectively. The carriage drive mechanism 1 abuts against the mode telescopic member 2, and the mode telescopic member 2 performs telescopic movement. The elastic element 94 also performs telescopic movement under the action of the mode telescopic member 2. The kinetic energy of the carriage drive mechanism 1 is stored as elastic potential energy through the elastic element 94. When the carriage drive mechanism 1 moves away from the mode telescopic member 2, the elastic potential energy of the elastic element 94 is converted into kinetic energy and acts on the mode telescopic member 2, so that the mode telescopic member 2 abuts against the limiting element 92, realizing automatic reset, and thus realizing the fixation of the paper picking or cleaning state.

[0104] Both the swing switching component 6 and the transmission component 8 are connected to the mounting bracket 9, which has a through hole 93. The abutment rod 21 passes through the through hole 93 and can extend and retract within the through hole 93.

[0105] Specifically, in this embodiment, the swing switching component 6 and the transmission component 8 are both connected to the mounting frame 9. The swing switching component 6 is located on the outside of the mounting frame 9, and one end of the transmission component 8 is connected to the swing switching component 6. The mounting frame 9 has a through hole 93, and the abutment rod 21 passes through the through hole 93 and can extend and retract within the through hole 93. By integrating the swing switching component 6, the transmission component 8, and the mode telescopic component 2 onto the mounting frame 9, the structure is simple to connect, has better overall integrity, is easy to assemble, and has high reliability.

[0106] The word carriage drive mechanism 1 includes a drive motor 11 and a word carriage 14. The word carriage 14 has an outwardly protruding actuating part 141 at one end facing the mode telescopic member 2. The drive motor 11 is connected to the word carriage 14 and is used to drive the word carriage 14 to move in a direction close to the mode telescopic member 2 so that the actuating part 141 abuts against the mode telescopic member 2.

[0107] Specifically, the carriage drive mechanism 1 of this embodiment includes a drive motor 11, a carriage 14, a first belt 12, and a first pulley 13. The carriage 14 has an outwardly protruding actuating part 141 at one end facing the mode telescopic member 2. The first belt 12 is connected to the carriage 14, with one end connected to the drive motor 11 and the other end connected to the first pulley 13. Under the action of the drive motor 11, the first belt 12 drives the carriage 14 to move along the guide rail 15 towards the mode telescopic member 2, so that the actuating part 141 abuts against the trigger rod 24 acting on the mode telescopic member 2. By using the carriage drive mechanism 1 as the driving force, the actuating part 141 moves with the carriage 14 towards the mode telescopic member 2 and acts on the trigger rod 24 of the mode telescopic member 2, causing the mode telescopic member 2 to perform telescopic movement. This design is simple in structure, highly reliable, and reduces production costs.

[0108] The swing switching component 6 includes a rotating gear 61, a swing arm body 62, a swing arm gear 621, a cleaning swing arm 63, and a cleaning gear 631. The transmission component 8 is connected to the rotating gear 61 and is used to drive the rotation of the rotating gear 61. The swing arm body 62 is connected to the rotating gear 61. The swing arm gear 621 is connected to one end of the swing arm body 62 and meshes with the rotating gear 61. The other end of the swing arm body 62 abuts against the mode telescopic component 2. The two ends of the cleaning swing arm 63 are respectively connected to the rotating gear 61 and the cleaning gear 631 and are used to drive the swing of the cleaning gear 631 so that the cleaning gear 631 is connected to or disconnected from the cleaning component 5. The cleaning gear 631 is located between the mode telescopic component 2 and the cleaning component 5 and meshes with the rotating gear 61. The rotating gear 61 is driven to rotate by the paper feeding drive mechanism 7 and switched to a paper picking state, a forward cleaning state, or a reverse cleaning state.

[0109] In the paper-taking state, the swing arm body 62 abuts against the side of the mode telescopic member 2 facing the cleaning gear 631, and the swing arm gear 621 is connected to the paper-taking roller 3 and disconnected from the cleaning member 5.

[0111] In the reverse cleaning state, the swing arm body 62 abuts against the side of the mode telescopic member 2 facing away from the cleaning gear 631. The swing arm gear 621 is disconnected from the cleaning component 5 and the paper take-up roller 3, while the cleaning gear 631 is connected to the cleaning component 5.

[0112] In the forward cleaning state, the rotation direction of the rotating gear 61 is opposite to that in the reverse cleaning state.

[0113] Specifically, the swing switching component 6 in this embodiment includes a rotating gear 61, a swing arm body 62, a swing arm gear 621, a cleaning swing arm 63, and a cleaning gear 631. The cleaning component 5 includes a cleaning roller 51, a third gear 511, a fourth gear 512, a fifth gear 513, a printer head cap 52, and a printhead scraper 53.

The fourth gear 512 is located at one end of the cleaning roller 51, and the fourth gear 512 and fifth gear 513 are located at the other end of the cleaning roller 51. The third gear 511 is disposed between the fourth gear 512 and the fifth gear 513. The fourth gear 512 meshes with the printhead scraper 53. Two sets of printhead scrapers 53 are provided, and the two sets of printhead scrapers 53 are respectively located on both sides of the printhead carriage. Figure 1 The printhead scraper 53 is shown on the right side. Another set of printhead scrapers 53 is also provided on the left side, but is not shown in the figure. The fifth gear 513 meshes with the printer nozzle cap 52, which is located at the bottom of the printhead carriage and has two caps. The transmission component 8 is connected to the rotating gear 61 and drives the rotating gear 61 to rotate. The swing arm body 62 is connected to the rotating gear 61, and there is damping between the rotating gear 61 and the swing arm body 62. The swing arm body 62 can rotate with the rotating gear 61. The swing arm gear 621 is connected to one end of the swing arm body 62, and the swing arm gear 621 meshes with the rotating gear 61. The other end of the swing arm body 62 abuts against the pattern extension. The abutment rod 21 of the retractable part 2 and the two ends of the cleaning swing arm 63 are respectively connected to the rotating gear 61 and the cleaning gear 631 and drive the cleaning gear 631 to swing so that the cleaning gear 631 is connected to or disconnected from the third gear 511 of the cleaning component 5. The cleaning gear 631 is located between the mode telescopic part 2 and the cleaning component 5, and the cleaning gear 631 meshes with the rotating gear 61. The rotating gear 61 is driven to rotate by the paper feeding drive mechanism 7 and switched to a paper picking state, a forward cleaning state or a reverse cleaning state respectively.

[0114] In the paper-taking state, the swing arm body 62 is located in the abutment rod 21 of the mode telescopic member 2 on the side facing the cleaning gear 631. The swing arm gear 621 is connected to the gear of the paper-taking roller 3 and disconnected from the third gear 511 of the cleaning member 5.

[0115] In the forward cleaning state, the swing arm body 62 is located on the side of the abutment rod 21 of the mode telescopic member 2 facing away from the cleaning gear 631. The swing arm gear 621 is connected to the third gear 511 of the cleaning component 5 and disconnected from the gear of the paper take-up roller 3. The cleaning gear 631 is disconnected from the third gear 511 of the cleaning component 5. The third gear 511 rotates under the action of the swing arm gear 621 and drives the fourth gear 512 to rotate. Correspondingly, the fourth gear 512 drives the print head scraper 53 to perform the cleaning operation in the forward direction.

[0116] In the reverse cleaning state, the swing arm body 62 abuts against the side of the abutment rod 21 of the mode telescopic member 2 facing away from the cleaning gear 631. The swing arm gear 621 is disconnected from the third gear 511 of the cleaning component 5 and the gear of the paper feed roller 3. The cleaning gear 631 is connected to the third gear 511 of the cleaning component 5. The third gear 511 rotates under the action of the swing arm gear 621, driving the fourth gear 512 to rotate. Correspondingly, the fourth gear 512 drives the printhead scraper 53 to perform a cleaning operation in the reverse direction. After the cleaning operation is completed, the fifth gear 513 drives the printer printhead cap 52 to seal and clean the nozzle of the print carriage 14, and catches the sponge that flows out of the printhead during the cleaning process. In the forward cleaning state, the rotation direction of the rotating gear 61 is opposite to that in the reverse cleaning state. By using the paper feeding drive mechanism 7 as a power source, and in conjunction with the swing switching component 6 and the gear meshing with it, a system for switching the paper feeding roller 3 and the cleaning component 5 is formed. By changing the relative position of the swing switching component 6 and the mode telescopic component 2, the system can switch between the paper feeding state, the forward cleaning state, and the reverse cleaning state. This saves drive components to the maximum extent, achieves a high degree of functional integration, simplifies the overall structure, and improves the reliability of the operation during the paper feeding or cleaning state.

[0117] The swing arm body 62 has an outwardly protruding protruding limiting part 623 and an abutting limiting part 622 that abuts against the mode telescopic member 2 at one end. The abutting limiting part 622 is located between the protruding limiting part 623 and the cleaning gear 631.

[0118] Specifically, in this embodiment, the swing arm body 62 has an outwardly protruding protruding limiting part 623 and an abutting limiting part 622 that abuts against the mode telescopic member 2 at one end. The abutting limiting part 622 is located between the protruding limiting part 623 and the cleaning gear 631. By setting the abutting limiting part 622 between the protruding limiting part 623 and the cleaning gear 631, the swing arm is prevented from crossing its working position by mechanical limiting, eliminating the transmission risk caused by overshoot or inaccurate positioning, preventing the power transmission path from failing due to incomplete gear meshing, and ensuring the reliability of the switching process.

[0119] The transmission component 8 includes multiple meshing transmission gears 81, with two transmission gears 81 located at both ends meshing with the paper feed roller 4 and the oscillating switching component 6, respectively.

[0120] Specifically, in this embodiment, the transmission component 8 includes multiple meshing transmission gears 81, all of which are mounted on the mounting frame 9 and may be located inside and / or on the inner side of the mounting frame 9. The two transmission gears 81 at both ends mesh with the first gear 41 of the paper feed roller 4 and the rotating gear 61 of the oscillating switching component 6, respectively. By meshing the two transmission gears 81 at both ends of the transmission component 8 with the first gear 41 of the paper feed roller 4 and the rotating gear 61 of the oscillating switching component 6, the power of the paper feed drive mechanism 7 is transmitted from the paper feed roller 4 to the oscillating switching component 6 via the transmission gears 81 of the transmission component 8. This reduces the number of power sources used, lowers production costs, simplifies the power transmission path, and increases reliability. Of course, in other embodiments, the transmission component 8 may also include components with transmission functions such as belt drives.

[0121] This embodiment also provides a printer, which includes the printing mode switching device as described above. The printing mode switching device includes a carriage drive mechanism 1, a mode extension member 2, a paper feed roller 3, a paper feed roller 4, a cleaning component 5, a swing switching member 6, a paper feed drive mechanism 7, and a transmission component 8. The paper feed drive mechanism 7 is connected to the paper feed roller 4. One end of the transmission component 8 is connected to the paper feed roller 4, and the other end of the transmission component 8 is connected to the swing switching member 6 and is used to drive the rotation of the swing switching member 6. The carriage drive mechanism 1 abuts against the mode extension member 2 and is used to drive the mode extension member 2 to extend and retract, so that the mode extension member 2 extends and the swing switching member 6 abuts against either side of the mode extension member 2, or the mode extension member 2 retracts and disconnects from the swing switching member 6. When the swing switching member 6 abuts against one side of the mode extension member 2, the swing switching member 6 and the paper feed roller 3... The paper feeding mechanism 7 is connected to and disconnected from the cleaning component 5. The rotation of the swing switching component 6 drives the paper feeding roller 3. When the swing switching component 6 abuts against the other side of the mode telescopic component 2, the swing switching component 6 is connected to the cleaning component 5 and disconnected from the paper feeding roller 3. The rotation of the swing switching component 6 drives the cleaning component 5. The paper feeding drive mechanism 7 transmits power to the paper feeding roller 4. On the one hand, it can drive the paper feeding roller 4 to rotate and drive the paper forward. On the other hand, since the paper feeding roller 4 is connected to the transmission component 8, the transmission component 8 transmits power from the paper feeding roller 4 to the swing switching component 6 and drives the swing switching component 6 to rotate. This allows the paper feeding drive mechanism 7 to not only drive the paper feeding roller 4 to move, but also drive the swing switching component 6 to rotate, switching between paper feeding or cleaning states. This reduces the number of paper feeding / cleaning motors used, lowers production costs, and has a simple structure and high reliability. The rotation of the swing switching component 6 drives the movement of the cleaning component 5; the carriage drive mechanism 1 can not only move back and forth along the guide rail 15, but also move along the carriage 14 in the direction of movement by abutting against the mode telescopic component 2. The mode telescopic component 2 forms a mechanical limit on the swing switching component 6 after the state is switched, so as to fix the state after the state is switched. The movement of the carriage drive mechanism 1 itself is used as the driving force, which reduces the number of state-fixing motors used, reduces production costs, and has a simple structure and high reliability.
