Description

TECHNICAL FIELD

[0001] The present application relates to printing technology, in particular to a ribbon cartridge, a printing system comprising the same and a printing method of the printing system. BACKGROUND

[0002] The ribbon cartridge comprises a cartridge body, a ribbon and a pair of intermeshing gears, most of the ribbon is stacked in a storage compartment of the cartridge body, another part is arranged between the two arms at the ends of the cartridge body, the gears are arranged in the storage compartment, and the ribbon passes through the meshing position of the two gears, so that when one of the two gears is driven by the driving force of the pin-type printer, the two intermeshing gears drive the ribbon to move in a specific direction in one direction.

[0003] At present, most of the ribbons of the ribbon cartridge are endless ribbons without joints. Such ribbons are fixed together at both ends of the long strip-shaped ribbon, and the joint is generally called a joint. The structure and performance of the joint of the endless ribbon type ribbon are different from those of other parts thereof, for example, the thickness and density of the joint are greater than those of other parts, and for example, the joint has undergone high temperature and high pressure treatment when being fixedly connected, resulting in glassy organization or even carbonized organization of the joint due to damage to the material organization characteristics, so that the ink penetration amount of the joint is much lower than that of the non-joint part, and in the extreme case, the ink penetration amount is almost zero. In addition, when the joint passes through the meshing position of the gears, the joint is easily cracked and broken due to the extrusion of the gears, thereby shortening the service life of the ribbon; and due to the relatively thick thickness of the joint, the joint is easily unstable in transmission and generates noise when passing through the meshing position of the gears. SUMMARY

[0004] In order to solve the above problems, the first object of the present application is to provide a ribbon cartridge capable of prolonging the service life of the ribbon, improving the running stability and reducing the running noise.

[0005] The second object of the present application is to provide a printing system provided with the above-mentioned ribbon cartridge.

[0006] The third object of the present application is to provide a printing method of the above-mentioned printing system.

[0007] In order to achieve the first object of the present application, the present application provides a ribbon cartridge comprising a cartridge body, a ribbon and a transmission mechanism, the two ends of the cartridge body are respectively provided with arms, the cartridge body has a storage compartment therein, a part of the ribbon is arranged in the storage compartment and another part is arranged between the two arms, the ribbon has a joint, an identification mark is arranged near the joint, and the transmission mechanism can drive the ribbon to move in a conveying direction. The transmission mechanism comprises a driving wheel module, a first driven wheel, a second driven wheel and a driving unit, the driving unit can drive one of the first driven wheel and the second driven wheel to engage with the driving wheel module and the other to disengage from the driving wheel module, and in the conveying direction, the first driven wheel is located at the downstream end of the second driven wheel.

[0008] As can be seen from the above, by designing the transmission mechanism, the ribbon cartridge can take the meshing transmission of the first driven wheel and the driving wheel module as the regular power source for ribbon conveying, and take the meshing transmission of the second driven wheel and the driving wheel module as the temporary power source for ribbon conveying, so as to control the driving unit to disengage the first driven wheel from the driving wheel module and control the second driven wheel to engage with the driving wheel module when the needle printer detects that the spout on the ribbon moves between the first driven wheel and the second driven wheel, thereby realizing the switching of the power source for ribbon conveying; since the spout of the ribbon is located between the first driven wheel and the second driven wheel at this time, the meshing of the second driven wheel and the driving wheel module does not extrude the spout of the ribbon when the second driven wheel engages with the driving wheel module to drive the ribbon conveying, and the meshing of the first driven wheel and the driving wheel module also does not extrude the spout of the ribbon when the first driven wheel and the driving wheel module are disengaged as the spout of the ribbon passes between the first driven wheel and the driving wheel module; after the spout of the ribbon moves to the downstream end of the first driven wheel, the needle printer controls the driving unit to disengage the second driven wheel from the driving wheel module and controls the first driven wheel to engage with the driving wheel module, thereby realizing that the spout of the ribbon is not extruded by the transmission mechanism throughout the entire life cycle of the ribbon, better preventing the spout of the ribbon from cracking and breaking, avoiding noise when the spout of the ribbon passes through the transmission mechanism, and ensuring the smoothness of the operation of the transmission mechanism.

[0012] From the above, the driving wheel module can better prevent the color band from being excessively relaxed at the transmission mechanism when the first driven wheel and the second driven wheel switch engagement with the driving wheel module, thereby improving the printing quality and the reliability of the color band conveying.

[0013] A further scheme is that the driving unit comprises a first rotating rod and a first operating rod, the first driven wheel is rotatably installed at a first end of the first rotating rod, the second driven wheel is rotatably installed at a second end of the first rotating rod, a middle part of the first rotating rod is rotatably connected with the cartridge body, a first end of the first operating rod is rotatably connected with the first rotating rod, a second end of the first operating rod is provided with a first docking part, and the first operating rod can control the first rotating rod to rotate so as to make the first driven wheel engage with the first driving wheel or make the second driven wheel engage with the second driving wheel.

[0014] From the above, through the design of the driving unit, the pin-type printer only needs to configure a single driving source to control the first operating rod to realize the switching engagement of the first driven wheel and the second driven wheel with the driving wheel module, thereby simplifying the structure of the color band cartridge and the pin-type printer.

[0018] As can be seen from the above, the above design can simplify the structure of the transmission mechanism, and reliably realize the switching engagement of the first driven wheel, the second driven wheel and the driving wheel module, so as to ensure that the ribbon spout is not squeezed when passing through the transmission mechanism, and prolong the service life of the ribbon cartridge and the ribbon.

[0019] Further, the driving wheel module, the first driven wheel and the second driven wheel all adopt gears; or the driving wheel module, the first driven wheel and the second driven wheel all adopt friction wheels.

[0020] As can be seen from the above, the driving wheel module, the first driven wheel and the second driven wheel can flexibly configure the type of the transmission wheel according to the material, performance and production cost of the ribbon, so as to improve the flexibility of the ribbon cartridge production.

[0023] Further, the needle printer is further provided with a fourth detection sensor and a fifth detection sensor.

[0035] First embodiment of the printing system Referring to Figures 1 to 3 , the printing system comprises a color band box 100 and a pin type printer, the color band box 100 is detachably installed in the installation cavity of the pin type printer, the pin type printer is provided with a print head 101, a fourth detection sensor 102, a fifth detection sensor 103, a driving head module, a driving device, a second driving device and a control unit, the control unit is electrically connected with the print head 101, the fourth detection sensor 102, the fifth detection sensor 103, the driving head module, the driving device and the second driving device respectively; wherein the second driving device is used for driving the color band 2 of the printer to move relative to the color band box 100, and controlling the print needle on the print head 101 to hit the color band 2, so as to form the characters and / or images to be presented.

[0036] The ribbon cartridge 100 comprises a cartridge body 1, a ribbon 2 and a transmission mechanism 3; the cartridge body 1 is provided with a supporting arm 11 at each end in the length direction of the cartridge body 1, and the cartridge body 1 has a ribbon storage compartment 10 for storing part of the ribbon 2. The ribbon 2 not stored in the ribbon storage compartment 10 passes through the two supporting arms 11 of the cartridge body 1 and is arranged across the two supporting arms 11, so that the print head 101 can move relative to the ribbon 2 in the length direction of the cartridge body 1. In the present application, the ribbon 2 is a closed-loop ribbon, i.e. the ribbon 2 is connected at the end of the long strip-shaped ribbon 2, and the connection between the beginning and the end of the ribbon 2 is the splicing joint 21 of the ribbon 2. The connection of the ribbon 2 at the beginning and the end is prior art, and therefore will not be described here. The ribbon 2 is provided with an identification mark 22 near the splicing joint 21, and the ribbon 2 is also provided with an identification mark 22 near the splicing joint 21. In the conveying direction X of the ribbon 2, the identification mark 22 can be arranged at the upstream end of the splicing joint 21 or at the downstream end of the splicing joint 21. In the present embodiment, the identification mark 22 is arranged at the downstream end of the ribbon 2. Of course, in some embodiments, the identification mark 22 can be arranged at the upstream end or the downstream end of the splicing joint 21 in the conveying direction X of the ribbon 2. The arrangement of the identification mark 22 is prior art, and therefore will not be described here. The transmission mechanism 3 is used to drive the ribbon 2 to move unidirectionally in the conveying direction X, so as to avoid the printing needle of the print head 101 from only hitting the same area of the ribbon 2, and also to prolong the service life of the ribbon 2.

[0037] The transmission mechanism 3 comprises a driving wheel module 31, a first driven wheel 32, a second driven wheel 33 and a driving unit 34. The driving wheel module 31 is used to be connected with the driving head module of the pin-type printer, so that the driving head module can drive the driving wheel module 31 to transmit. Along the conveying direction X, the first driven wheel 32 is located at the downstream end of the second driven wheel 33, and the driving wheel module 31, the first driven wheel 32 and the second driven wheel 33 are all arranged in the ribbon storage compartment 10. The driving unit 34 is used to drive one of the first driven wheel 32 and the second driven wheel 33 to engage with the driving wheel module 31, and the other one to disengage from the driving wheel module 31, that is, the driving wheel module 31 can only engage with the first driven wheel 32 or the second driven wheel 33 at least in a certain period of time, and cannot engage with the first driven wheel 32 and the second driven wheel 33 at the same time. The certain period of time is that the splicing end 21 of the ribbon 2 enters between the first driven wheel 32 and the second driven wheel 33 to the downstream end of the first driven wheel 32 along the conveying direction X. Since the ribbon 2 in the present application is a closed loop type ribbon, when the ribbon 2 is installed, it passes through the area between the engagement position of the first driven wheel 32 and the driving wheel module 31 and the engagement position of the second driven wheel 33 and the driving wheel module 31, that is, the first driven wheel 32 does not have the functions of winding and unwinding the ribbon 2, and only drives the ribbon 2 to move along the conveying direction X. The second driven wheel 33 does not have the functions of winding and unwinding the ribbon 2, and only drives the ribbon 2 to move along the conveying direction X. The driving wheel module 31 winds and unwinds the ribbon 2, and only drives the ribbon 2 to move along the conveying direction X. The driving unit 34 is used to be connected with the driving device of the pin-type printer, so as to be controlled by the driving device to make the first driven wheel 32 engage with the driving wheel module 31 and the second driven wheel 33 disengage from the driving wheel module 31, or to make the first driven wheel 32 disengage from the driving wheel module 31 and the second driven wheel 33 engage with the driving wheel module 31.

[0038] In the embodiment, the driving wheel module 31 comprises a first driving wheel 311 and a second driving wheel 312, the driving unit 34 comprises a first rotating rod 341 and a first operating rod 342, and the ribbon cartridge 100 further comprises a first detection sensor 4. The first detection sensor 4 is arranged in the ribbon storage compartment 10, and along the conveying direction X, the first detection sensor 4 is located between the first driven wheel 32 and the second driven wheel 33, and the detection end of the first detection sensor 4 is arranged towards the ribbon 2. The first detection sensor 4 is used to detect the identification mark 22 on the ribbon 2, so as to assist the control unit of the pin-type printer to identify and detect the position of the splicing end 21 of the ribbon 2, thereby assisting the control unit to control the driving device and the driving unit 34 to drive the first driven wheel 32 to engage with the first driving wheel 311 and the second driven wheel 33 to disengage from the second driving wheel 312, or to drive the first driven wheel 32 to disengage from the first driving wheel 311 and the second driven wheel 33 to engage with the second driving wheel 312. The detection and identification mode of the first detection sensor 4 on the identification mark 22 is the prior art, and thus will not be described here.

[0039] Furthermore, to facilitate communication between the first detection sensor 4 and the control unit of the dot matrix printer, a connection contact point is provided on the housing 1. This connection contact point is electrically connected to the first detection sensor 4 and is also used to connect with a matching electrical contact point inside the dot matrix printer, thereby establishing communication between the first detection sensor 4 and the control unit. By integrating the first detection sensor 4, the ribbon cartridge 100 can improve the accuracy of detecting the position of the identification mark 22, enabling more precise control of the switching engagement between the first driven wheel 32, the second driven wheel 33, and the drive wheel module 31. On the other hand, it also simplifies the structural layout within the dot matrix printer and prevents damage to the detection sensor ribbon cartridge 100 during disassembly and assembly when the detection sensor of the auxiliary control drive unit 34 is installed inside the dot matrix printer.

[0040] As described above, the drive wheel module 31 includes a first drive wheel 311 and a second drive wheel 312. The first drive wheel 311 engages with the first driven wheel 32, and the second drive wheel 312 engages with the second driven wheel 33 to achieve the transmission of the ribbon 2. That is, the first drive wheel 311 is located downstream of the second drive wheel 312. By configuring the first drive wheel 311, which engages independently with the first driven wheel 32, and the second drive wheel 312, which engages independently with the second driven wheel 33, the drive wheel module 31 can better prevent the ribbon 2 from becoming excessively slack at the transmission mechanism 3 when the first driven wheel 32 and the second driven wheel 33 switch engagement with the drive wheel module 31 (compared to the drive wheel module 31 having only one drive wheel), thereby improving printing quality and the reliability of ribbon 2 transmission.

[0041] like Figure 3 As shown, a first driven wheel 32 is rotatably mounted on the first end of a first rotating rod 341 about its own axis of rotation, and a second driven wheel 33 is rotatably mounted on the second end of the first rotating rod 341 about its own axis of rotation. The middle part of the first rotating rod 341 is rotatably connected to the housing 1. The housing 1 has a clearance groove 12 on the movement path of the first driven wheel 32 and the second driven wheel 33 to avoid the rotation axes of the first driven wheel 32 and the second driven wheel 33 during movement. In some embodiments, the clearance groove 12 is an arc-shaped groove that matches the rotation path of the first driven wheel 32 and the second driven wheel 33; in some embodiments, the clearance groove 12 can be a first straight strip groove extending along the height direction of the housing 1, while the first rotating rod 341 has a second straight strip groove extending along its own extension direction. The first driven wheel 32 can slide within a corresponding first strip groove and a corresponding second strip groove, and the second driven wheel 33 can slide within a corresponding first strip groove and a corresponding second strip groove, thereby ensuring the reliability of the rotation of the first rotating rod 341.

[0042] The first end of the first operating rod 342 is rotationally connected with the first rotating rod 341, and the second end of the first operating rod 342 is provided with a first connecting part 3421 for matching connection with a driving device of the pin-type printer, so that the driving device can drive the first operating rod 342 to control the rotation of the first rotating rod 341, thereby realizing the engagement of the first driven wheel 32 with the first driving wheel 311, the disengagement of the second driven wheel 33 from the second driving wheel 312, or the disengagement of the first driven wheel 32 from the first driving wheel 311, and the engagement of the second driven wheel 33 with the second driving wheel 312. Through the design of the driving unit 34, the pin-type printer only needs to be provided with a single driving source to control the first operating rod 342, so as to realize the switching engagement of the first driven wheel 32, the second driven wheel 33 and the driving wheel module 31, thereby simplifying the structure of the ribbon cartridge 100 and the pin-type printer.

[0043] In the embodiment, the first driving wheel 311, the second driving wheel 312, the first driven wheel 32 and the second driven wheel 33 are all gear wheels; in some embodiments, the first driving wheel 311, the second driving wheel 312, the first driven wheel 32 and the second driven wheel 33 can also all be friction wheels; in some embodiments, the first driving wheel 311 and the first driven wheel 32 are gear wheels, and the second driving wheel 312 and the second driven wheel 33 are friction wheels, or the first driving wheel 311 and the first driven wheel 32 are friction wheels, and the second driving wheel 312 and the second driven wheel 33 are gear wheels. It can be seen that the driving wheel module 31, the first driven wheel 32 and the second driven wheel 33 can be flexibly configured in terms of the type of the driving wheel according to the material and performance of the ribbon 2 and the production cost, thereby improving the flexibility of the production of the ribbon cartridge 100.

[0044] In addition, in order to further avoid the cracking and breaking of the splicing port 21 of the ribbon 2, the fourth detection sensor and the fifth detection sensor 103 are arranged; wherein, along the conveying direction X, the fourth detection sensor 102 is located at the upstream end of the second driven wheel 33, the fourth detection sensor 102 is used for detecting the position of the identification mark 22, the fifth detection sensor 103 is located between the fourth detection sensor 102 and the second driven wheel 33, and the fifth detection sensor 103 is used for detecting the position of the identification mark 22. The area between the fourth detection sensor 102 and the fifth detection sensor 103 is the printing area of the print head 101, when the splicing port 21 of the ribbon 2 moves into the printing area, the control unit can control the driving head device to make the splicing port 21 of the ribbon 2 directly move to the downstream end of the printing area, thereby preventing the print head 101 from pressing the splicing port 21, and reducing the damage speed of the splicing port 21. In some embodiments, only one detection sensor such as the fourth detection sensor 102 can be arranged, and at this time, the detection sensor is located between the print head 101 and the upstream end of the supporting arm 11.

[0045] In summary, through the design of the transmission mechanism 3 of the ribbon cartridge 100, when the ribbon 2 is normally transmitted, the meshing transmission of the first transmission wheel and the first driving wheel 311 serves as the regular power source for the transmission of the ribbon 2, and the meshing transmission of the second driven wheel 33 and the second driving wheel 312 serves as the temporary power source for the transmission of the ribbon 2. When the first detection sensor 4 detects that the spout 21 of the ribbon 2 moves between the first driven wheel 32 and the second driven wheel 33 (identified by recognizing the identification mark 22, and the control unit of the auxiliary pin-type printer determines), the control unit controls the driving device to drive the first operating rod 342 of the driving unit 34, so that the first operating rod 342 moves to control the first driven wheel 32 to disengage from the first driving wheel 311, and the second driven wheel 33 engages with the second driving wheel 312, realizing the temporary switching of the power source for the transmission of the ribbon 2. Since the spout 21 of the ribbon 2 is located between the first driven wheel 32 and the second driven wheel 33 at this time, when the second driven wheel 33 drives the second driving wheel 312 to transmit the ribbon 2, the meshing transmission of the second driven wheel 33 and the second driving wheel 312 will not extrude the spout 21 of the ribbon 2, and since the first driven wheel 32 and the first driving wheel 311 are separated, the spout 21 will not be extruded by the first driven wheel 32 and the first driving wheel 311 when passing between the first driven wheel 32 and the first driving wheel 311. When the spout 21 of the ribbon 2 is transmitted by the second driven wheel 33 and the second driving wheel 312 to the downstream end of the first driven wheel 32 and the second driven wheel 33 (this movement can be realized by controlling the driving of the driving head module through the preset program of the pin-type printer), the control unit of the pin-type printer controls the driving device to control the movement of the first operating rod 342, so that the second driven wheel 33 is separated from the second driving wheel 312, and the first driven wheel 32 engages with the first driving wheel 311, so that the power source for the transmission of the ribbon 2 is switched to the regular power source. It can be seen that through the structure of the transmission mechanism, the ribbon 2 is not extruded by the transmission mechanism 3 throughout its entire life, which better prevents the spout 21 of the ribbon 2 from cracking and breaking, avoids noise when the spout 21 of the ribbon 2 passes through the transmission mechanism 3, and ensures the smoothness of the operation of the transmission mechanism 3. During the switching engagement of the first driven wheel 32, the second driven wheel 33 and the driving wheel module 31, the printing head 101 of the printer can be controlled to pause the printing operation or keep the continuous printing operation as appropriate.

[0046] In addition, when the fourth detection sensor 102 detects the identification mark 22 at the splicing joint 21 of the color ribbon 2, the control unit of the pin-type printer controls the print head 101 to pause the printing operation, and controls the drive head module to control the transmission mechanism 3 to accelerate the movement of the color ribbon 2 along the conveying direction X until the identification mark 22 at the splicing joint 21 of the color ribbon 2 is detected by the fifth detection sensor 103, and then the control unit controls the print head 101 to continue the printing operation, and controls the drive head module to control the transmission mechanism 3 to restore the normal conveying speed of the color ribbon 2. It should be noted that when the pin-type printer does not have the fifth detection sensor 103, the control unit controls the drive head module to control the transmission mechanism 3 to accelerate the movement of the color ribbon 2 along the conveying direction X by a preset distance, and then controls the print head 101 to continue the printing operation and the transmission mechanism 3 to restore the normal conveying speed of the color ribbon 2. Similarly, the detection and identification of the identification mark 22 by the fourth detection sensor 102 and the fifth detection sensor 103 are prior art, and thus will not be described here.

[0047] The printing system can effectively prolong the service life of the color ribbon cartridge 100 and the color ribbon 2, improve the conveying stability of the color ribbon 2, and reduce the running noise of the color ribbon cartridge 100 by configuring the color ribbon cartridge 100.

The first driven wheel 32 is rotatably installed at a first end of the second operating rod 343 about the rotation axis thereof, and the first driven wheel 32 is slidably connected with the first guide groove 23, so that the second operating rod 343 can control the first driven wheel 32 to move along the first guide groove 23 relative to the first driving wheel 311 to engage or disengage the first driven wheel 32 with the first driving wheel 311. A second docking portion is arranged at a second end of the second operating rod 343, and the second docking portion is used to dock with the driving device of the pin-type printer to be driven by the driving device.

[0049] The second driven wheel 33 is rotatably installed at the first end of the third operating lever 344 about its own rotation axis, and the second driven wheel 33 is in sliding connection with the second guide groove 24, so that the third operating lever 344 can control the second driven wheel 33 to move along the second guide groove 24 relative to the second driving wheel 312 to engage or disengage the second driven wheel 33 with the second driving wheel 312; the second end of the third operating lever 344 is provided with a third docking portion 3431, which is used to dock with the driving device of the pin-type printer to be controlled and driven by the driving device.

[0050] In some embodiments, the second operating lever 343 is provided with a first guide column in sliding connection with the first guide groove 23, and the third operating lever 344 is provided with a second guide column in sliding connection with the second guide groove 24; this design can ensure the positions of the second operating lever 343 and the third operating lever 344, so as to ensure that the second operating lever 343 and the third operating lever 344 are accurately docked with the driving device when the ribbon cartridge 100 is installed into the pin-type printer.

[0051] In some embodiments, a first insertion hole 13 can be provided on one of the second operating lever 343 and the cartridge body 1, and a first limiting pin can be provided on the other, which is slidably inserted into the first insertion hole 13; a second insertion hole 13 can be provided on one of the third operating lever 344 and the cartridge body 1, and a second limiting pin can be provided on the other, which is slidably inserted into the second insertion hole 13; similarly, this design can ensure the positions of the second operating lever 343 and the third operating lever 344, so as to ensure that the second operating lever 343 and the third operating lever 344 are accurately docked with the driving device when the ribbon cartridge 100 is installed into the pin-type printer.

[0052] In this embodiment, the second operating lever 343 is used to control the movement of the first driven wheel 32 to engage or disengage with the first driving wheel 311, and the third operating lever 344 is used to control the movement of the second driven wheel 33 to disengage or engage with the second driving wheel 312, which can better avoid the slack of the ribbon 2 at the transmission mechanism 3, further improve the printing quality and the reliability of the ribbon 2 transmission, and can ensure that the print head 101 always maintains continuous printing operation during the switching process of the conventional power source and the temporary power source of the ribbon 2.

[0053] It should be noted that the timing of controlling the first driven wheel 32 to engage / disengage with the first driving wheel 311 and the second driven wheel 33 to disengage / engage with the second driving wheel 312 is the same as that of the first embodiment, and thus will not be described here.

[0054] Third embodiment of the printing system The difference between this embodiment and the first embodiment of the printing system lies in the structure of the driving wheel module. Specifically, in this embodiment: The driving unit 34 is similar to the driving unit in the first embodiment of the printing system, and specifically includes a second rotating rod and a fourth operating rod. The first driven wheel is rotatably installed at a first end of the second rotating rod, and the second driven wheel is rotatably installed at a second end of the second rotating rod. The second rotating rod is rotatably connected to the box body at a middle portion thereof. A first end of the fourth operating rod is rotatably connected to the second rotating rod, and a second end of the fourth operating rod is provided with a fourth abutting portion. The fourth operating rod can be driven by the driving device of the pin-type printer to control the second rotating rod to rotate, so that the first driven wheel or the second driven wheel is engaged with the third driving wheel. Similarly, the box body can be provided with a corresponding avoiding slot, and the second rotating rod can be provided with a corresponding linear slot to cooperate with the corresponding driven wheel.

[0055] The design of the embodiment can simplify the structure of the transmission mechanism, reliably realize the switching engagement of the first driven wheel, the second driven wheel and the third driving wheel, ensure that the splicing portion of the ribbon is not squeezed when passing through the transmission mechanism, and prolong the service life of the ribbon cartridge and the ribbon. When the transmission structure may have a deficiency, the ribbon may be temporarily relaxed when the first driven wheel, the second driven wheel and the third driving wheel are switched and engaged.

[0056] Fourth embodiment of the printing system In combination Figure 5 The difference between the embodiment and the second embodiment of the printing system is the structure of the driving wheel module 31. Specifically, in the embodiment: The driving wheel module 31 is a third driving wheel 313. The box body 1 is provided with a third guide slot and a fourth guide slot. The driving unit 34 includes a fifth operating rod 345 and a sixth operating rod 346. The first driven wheel 32 is connected to a first end of the fifth operating rod 345. A second end of the fifth operating rod 345 is provided with a fifth abutting portion. The fifth operating rod 345 can control the first driven wheel 32 to slide along the third guide slot to engage or disengage with the third driving wheel 313. The second driven wheel 33 is connected to a first end of the sixth operating rod 346. A second end of the sixth operating rod 346 is provided with a sixth abutting portion. The sixth operating rod 346 can control the second driven wheel 33 to slide along the fourth guide slot to engage or disengage with the third driving wheel 313.

[0057] Similarly, the design of the embodiment can simplify the structure of the transmission mechanism 3, reliably realize the switching engagement of the first driven wheel 32, the second driven wheel 33 and the third driving wheel 313, ensure that the splicing portion 21 of the ribbon 2 is not squeezed when passing through the transmission mechanism 3, and prolong the service life of the ribbon cartridge 100 and the ribbon 2. When the transmission structure may have a deficiency, the ribbon 2 may be temporarily relaxed when the first driven wheel 32, the second driven wheel 33 and the third driving wheel 313 are switched and engaged.

[0058] Fifth embodiment of the printing system In combination Figure 6The difference between the embodiment and the first to fourth embodiments of the printing system is that, in the embodiment: The first detection sensor 4 is no longer arranged in the ribbon cartridge 100, and a jack 13 is arranged at the position of the first detection sensor 4, which is communicated to the ribbon storage chamber 10 of the cartridge body 1. Meanwhile, a third detection sensor 104 is arranged in the pin-type printer, which is arranged in matching with the jack 13, so that when the ribbon cartridge 100 is installed in the pin-type printer, the third detection sensor 104 is inserted into the ribbon storage chamber 10 through the jack 13, and then located between the first driven wheel 32 and the second driven wheel 33.

[0059] In the embodiment, the function, the purpose of arrangement, and the role of implementation of the third detection sensor 104 are the same as those of the first detection sensor 4 in the first embodiment of the printing system, and thus will not be described here.

[0060] By arranging the third detection sensor 104 in the pin-type printer to replace the first detection sensor 4, the production and use cost of the ribbon cartridge 100 can be reduced.

[0061] Sixth embodiment of the printing system In combination Figure 7 The difference between the embodiment and the first to fourth embodiments of the printing system is that, in the embodiment: The first detection sensor 4 is no longer arranged in the ribbon cartridge 100, and a second detection sensor 105 is arranged in the pin-type printer, which is preferably located at the downstream end support arm 11 of the cartridge body 1.

[0062] In the embodiment, the function, the purpose of arrangement, and the role of implementation of the second detection sensor 105 are the same as those of the first detection sensor 4 in the first embodiment of the printing system, and thus will not be described here.

[0063] When the second detection sensor 105 detects the identification mark 22 on the ribbon 2, the control unit controls the drive head module to drive the transmission mechanism 3, so that the ribbon 2 is first moved to the first driven wheel 32 and the second driven wheel 33 by a first preset distance; then, the control unit controls the drive unit 34 to make the first driven wheel 32 disengage from the meshing with the driving wheel module 31, and the second driven wheel 33 meshes with the driving wheel module 31; then the control unit continues to control the drive head module to drive the transmission mechanism 3 to move the ribbon 2 to the downstream end of the first driven wheel 32 by a second preset distance; finally, the control unit controls the drive unit 34 to make the second driven wheel 33 disengage from the meshing with the driving wheel module 31, and the first driven wheel 32 meshes with the driving wheel module 31.

[0064] First embodiment of the printing method of the printing system The printing system in the embodiment is the printing system described in any one of the first to fourth embodiments of the printing system.

[0065] The printing method in the embodiment includes: The detection signal of the first detection sensor 4 is acquired to determine whether the identification mark 22 on the ribbon 2 moves to the first detection sensor 4. If yes, the driving device is controlled to drive the driving unit 34 to drive the first driven wheel 32 to disengage from the meshing with the driving wheel module 31 and to engage the second driven wheel 33 with the driving wheel module 31.

[0066] Then, the driving head module is controlled to drive the driving wheel module 31 to drive the ribbon 2 to move by a third preset distance until the identification mark 22 on the ribbon 2 moves to the downstream end of the first driven wheel 32.

[0067] Then, the driving device is controlled to drive the driving unit 34 to drive the second driven wheel 33 to disengage from the meshing with the driving wheel module 31 and to engage the first driven wheel 32 with the driving wheel module 31.

[0068] The detection signal of the fourth detection sensor 102 is acquired to determine whether the identification mark 22 on the ribbon 2 moves to the fourth detection sensor 102. If yes, the driving head module is controlled to drive the driving wheel module 31 to drive the ribbon 2 to move at an accelerated speed until the fifth detection sensor 103 detects the identification mark 22 on the ribbon 2. During the process, the printing head 101 is paused for printing.

[0069] The detection signal of the fifth detection sensor 103 is acquired to determine whether the identification mark 22 on the ribbon 2 moves to the fifth detection sensor 103. If yes, the driving head module is controlled to drive the driving wheel module 31 to drive the ribbon 2 to move at a preset moving speed. During the process, the printing head 101 can normally perform printing.

[0070] The printing method of the printing system in the second embodiment The printing system in the embodiment is the printing system described in the fifth embodiment of the printing system.

[0071] The printing method in the embodiment includes: The detection signal of the third detection sensor 104 is acquired to determine whether the identification mark 22 on the ribbon 2 moves to the third detection sensor 104. If yes, the driving device is controlled to drive the driving unit 34 to drive the first driven wheel 32 to disengage from the meshing with the driving wheel module 31 and to engage the second driven wheel 33 with the driving wheel module 31.

[0072] Then, the driving head module drives the driving wheel module 31 to drive the color ribbon 2 to move at a third preset distance, so that the identification mark 22 on the color ribbon 2 moves to the downstream end of the first driven wheel 32.

[0073] Then, the driving device drives the driving unit 34 to drive the driving unit 34 to drive the second driven wheel 33 to disengage from the engagement with the driving wheel module 31, and to engage the first driven wheel 32 with the driving wheel module 31.

[0074] The detection signal of the fourth detection sensor 102 is obtained to determine whether the identification mark 22 on the color ribbon 2 moves to the fourth detection sensor 102, and if so, the driving head module drives the driving wheel module 31 to drive the color ribbon 2 to move at an accelerated speed until the fifth detection sensor 103 detects the identification mark 22 on the color ribbon 2. During this process, the printhead 101 is paused for printing.

[0075] The detection signal of the fifth detection sensor 103 is obtained to determine whether the identification mark 22 on the color ribbon 2 moves to the fifth detection sensor 103, and if so, the driving head module drives the driving wheel module 31 to drive the color ribbon 2 to move at a preset moving speed. During this process, the printhead 101 can normally perform printing.

[0076] The third embodiment of the printing method of the printing system The printing system in this embodiment is the printing system described in the sixth embodiment of the printing system.

[0077] The printing method of this embodiment includes: The first preset distance and the second preset distance are obtained, wherein the first preset distance and the second preset distance can be parameters set by the user input into the control program, for example, the user directly inputs the numerical values of the first preset distance and the second preset distance into the control program, or the user directly inputs at least one information parameter such as the model and manufacturer information of the color ribbon cartridge 100 into the control program, and then the control program automatically identifies and judges the information (such as the model and manufacturer information) of the color ribbon cartridge 100 and automatically generates the first preset distance and the second preset distance, or when the color ribbon cartridge 100 is provided with a chip, the first preset distance and the second preset distance are automatically generated by reading the information of the color ribbon cartridge 100 stored in the chip memory.

[0078] The detection signal of the second detection sensor 105 is obtained to determine whether the identification mark 22 on the color ribbon 2 moves to the second detection sensor 105, and if so, it is determined whether the color ribbon 2 has moved the first preset distance.

[0079] If the identification mark 22 of the ribbon 2 moves a first preset distance from the second detection sensor 105, the control driving device drives the driving unit 34, so that the driving unit 34 drives the first driven wheel 32 to disengage from the meshing with the driving wheel module 31, and the second driven wheel 33 is engaged with the driving wheel module 31.

[0080] Then, the control driving head module drives the driving wheel module 31 to drive, so that the ribbon 2 is driven to move a second preset distance, and the identification mark 22 on the ribbon 2 moves to the downstream end of the first driven wheel 32.

[0081] Then, the control driving device drives the driving unit 34, so that the driving unit 34 drives the second driven wheel 33 to disengage from the meshing with the driving wheel module 31, and the first driven wheel 32 is engaged with the driving wheel module 31.

[0082] The detection signal of the fourth detection sensor 102 is acquired, and it is judged whether the identification mark 22 of the ribbon 2 moves to the fourth detection sensor 102. If yes, the control driving head module drives the driving wheel module 31 to drive, so that the ribbon 2 is driven to accelerate to move to the fifth detection sensor 103 to detect the identification mark 22 on the ribbon 2; in this process, the print head 101 is paused for printing work.

[0083] The detection signal of the fifth detection sensor 103 is acquired, and it is judged whether the identification mark 22 of the ribbon 2 moves to the fifth detection sensor 103. If yes, the control driving head module drives the driving wheel module 31 to drive, so that the ribbon 2 is driven to move at a preset moving speed; in this process, the print head 101 can normally print work.

[0084] As can be seen from the above, by the above printing method, the nozzle 21 of the ribbon 2 can be avoided to be pressed by the transmission mechanism 3 and hit by the print head 101 of the needle type printer during the working process of the needle type printer, so that the service life of the ribbon cartridge 100 and the ribbon 2 is effectively prolonged, the service life of the print head 101 is prolonged, the transmission stability of the ribbon 2 is improved, and the running noise of the ribbon cartridge 100 is reduced.

[0085] Finally, it should be emphasized that the above only describes the preferred embodiments of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
