Description

Technical Field

[0001] This application relates to the field of printer technology, and more particularly to a ribbon cartridge and a printer. Background Technology

[0002] In the field of barcode and label printing, ribbon cartridges are an indispensable and important component, especially in warehouse management, logistics and transportation, and retail industries. Barcodes and labels are widely used to track and identify items, and ribbon cartridges ensure the readability and durability of barcodes and labels by providing clear and durable printing results.

[0003] However, in practical applications, the ribbon portion of the ribbon cartridge is prone to tearing and breakage. When the ribbon outside the cartridge is subjected to external forces, such as the traction force of the print head or operator error, the ribbon itself is brittle and tensile sensitive, and it is easy to break due to sudden changes in external forces. Once the ribbon breaks, it will not only interrupt the printing task, but may also damage the printing equipment, increasing maintenance costs and operational difficulties. Utility Model Content

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0046] In the field of barcode and label printing, ribbon cartridges are an indispensable and important component, especially in warehouse management, logistics and transportation, and retail industries. Barcodes and labels are widely used to track and identify items, and ribbon cartridges ensure the readability and durability of barcodes and labels by providing clear and durable printing results.

[0047] However, in practical applications, the ribbon portion of the ribbon cartridge is prone to tearing and breakage. When the ribbon outside the cartridge is subjected to external forces, such as the traction force of the print head or operator error, the ribbon itself is brittle and tensile sensitive, and it is easy to break due to sudden changes in external forces. Once the ribbon breaks, it will not only interrupt the printing task, but may also damage the printing equipment, increasing maintenance costs and operational difficulties.

[0048] Please refer to Figures 1 to 3b In order to solve the above-mentioned technical problems, this application proposes a ribbon cartridge 100 and a printer 1000. The ribbon cartridge 100 is used in the printer 1000, and the ribbon cartridge 100 includes: a cartridge body 1, a recycle ribbon roll group 2, and a dispense ribbon roll group 3.

[0049] The cartridge 1 encloses a printing space 1a. A recycle ribbon roll 2 is rotatably mounted on the cartridge 1 about its axis, and a dispensing ribbon roll 3 is rotatably mounted on the cartridge 1 about its axis. Specifically, the dispensing ribbon roll 3 is used to unwind the ribbon 500, and the recycle ribbon roll 2 is used to rewind the ribbon 500. At least a portion of the ribbon 500 between the dispensing ribbon roll 3 and the recycle ribbon roll 2 is located in the printing space 1a. When the ribbon 500 in the printing space 1a is subjected to an external force, at least one of the dispensing ribbon roll 3 and the recycle ribbon roll 2 rotates to release a portion of the ribbon 500 into the printing space 1a.

[0050] Understandably, when the ribbon 500 located in the printing space 1a is subjected to external force (such as stretching and jamming that may occur during the printing process), at least one of the ribbon delivery roll 3 and the ribbon return roll 2 will rotate accordingly to release part of the ribbon 500 into the printing space 1a. By increasing the size of the ribbon 500 located in the printing space 1a, it is ensured that the ribbon 500 has a certain buffer and adjustment space when subjected to external force, which can effectively reduce the influence of external traction force on the ribbon 500 located outside the cartridge 1, thereby reducing the risk of ribbon 500 breakage caused by sudden external force and improving the stability and reliability of the printing process.

[0051] Specifically, the housing 1 is hollow, used to house and install the recycle ribbon roll 2 and the dispensing ribbon roll 3. The housing 1 also has two opposing openings, allowing the ribbon 500 to be exposed to the printing space 1a outside the housing 1 through these openings. It is understood that since the recycle ribbon roll 2 and the dispensing ribbon roll 3 are both located inside the housing 1, the housing 1 can protect the dispensing ribbon roll 3, the recycle ribbon roll 2, and the ribbon 500 wound around them. During actual operation, it can maximize the isolation of external influences on the ribbon 500's transmission, reducing the risk of ribbon breakage to a certain extent.

[0052] Furthermore, in some embodiments, the housing 1 has a side parallel to the axis of the dispensing ribbon roll 3 or the recycling ribbon roll 2. Two protrusions are spaced apart on this side, and the space formed by the two protrusions and the side is the printing space 1a. Two openings are respectively provided at the two protrusions so that the ribbon 500 passing through the two openings is located in the printing space 1a. With this arrangement, the ribbon 500 and the side of the housing 1 are spaced apart, which can effectively reduce the friction between the ribbon 500 and the housing 1, thereby reducing the risk of ribbon breakage caused by contact friction between the ribbon 500 and the housing 1.

[0053] Please refer to Figure 2 The axis of the dispensing ribbon roll 3 is parallel to the axis of the recycle ribbon roll 2. On one hand, the parallelism of the axes of the dispensing ribbon roll 3 and the recycle ribbon roll 2 allows for more efficient use of the internal space of the housing 1. By rationally arranging the layout of the dispensing ribbon roll 3 and the recycle ribbon roll 2, more ribbons 500 can be accommodated without increasing the overall size, maintaining the compactness of the ribbon housing 100 structure. On the other hand, because the axes of the dispensing ribbon roll 3 and the recycle ribbon roll 2 are parallel, the path for the ribbon 500 connected to them to move from the dispensing ribbon roll 3 to the recycle ribbon roll 2 is more direct, reducing bending and twisting of the ribbon 500 during transmission. This improves the stability of the ribbon 500's journey, reduces the risk of tape jamming, and also reduces unnecessary twisting and friction, thereby reducing the friction between the ribbon 500 and the housing 1 or other components, reducing wear during the journey, and further extending the service life of the ribbon 500 and related components.

[0054] Please refer to Figure 3a , Figure 3b as well as Figure 4In this embodiment, the recycle ribbon roll 2 has a recycle shaft 21, and the dispensing ribbon roll 3 has a dispensing shaft 31. Furthermore, the housing 1 includes a first housing 11 and a second housing 12. The first housing 11 includes a first mounting portion 111 and a second mounting portion 112. The second housing 12 includes a third mounting portion 121 and a fourth mounting portion 122. The second housing 12 and the first housing 11 cover and enclose to form a receiving cavity for accommodating the recycle ribbon roll 2 and the dispensing ribbon roll 3. The third mounting portion 121 is correspondingly disposed with the first mounting portion 111 and is used to couple with the recycle shaft 21 so that the recycle ribbon roll 2 can rotate around the axial direction of the recycle shaft 21. The fourth mounting portion 122 is correspondingly disposed with the second mounting portion 112 and is used to couple with the dispensing shaft 31 so that the dispensing ribbon roll 3 can rotate around the axial direction of the dispensing shaft 31.

[0055] Continue to refer to Figure 3a and Figure 3b Specifically, in the above embodiments, the housing 1 has a split design, including a first housing 11 and a second housing 12, wherein the first housing 11 and the second housing 12 are detachably connected and are used to define a receiving cavity for the installation of the recycling ribbon roll 2 and the dispensing ribbon roll 3. In actual application, when the ribbon 500 is transferred between the recycling ribbon roll 2 and the dispensing ribbon roll 3, malfunctions such as jamming or ribbon breakage may occur. The split design of the first housing 11 and the second housing 12 allows for immediate disassembly of the housing 1, quick troubleshooting of operational faults, and also facilitates the installation and subsequent replacement of related components located in the receiving cavity.

[0056] The first housing 11 has a first mounting part 111 and a second mounting part 112, and the second housing 12 has a third mounting part 121 and a fourth mounting part 122. The first mounting part 111 and the third mounting part 121 are correspondingly arranged to define the mounting position of the recycling spindle 21, so that the recycling ribbon roll 2 is installed between the first mounting part 111 and the third mounting part 121. The second mounting part 112 and the fourth mounting part 122 are correspondingly arranged to define the mounting position of the dispensing spindle 31, so that the dispensing ribbon roll 3 is installed between the second mounting part 112 and the fourth mounting part 122. This ensures the accuracy of the mounting positions of the two rolls and guarantees the stability and consistency of the movement path of the ribbon 500 during the printing process.

[0057] In some embodiments, please continue to refer to Figures 3a to 4The first mounting part 111 and the second mounting part 112 respectively include a first mounting hole and a second mounting hole. The end of the retrieval shaft 21 is used to be installed in the first mounting hole, and the end of the dispensing shaft 31 is used to be installed in the second mounting hole. It can be understood that the inner diameter of the first mounting hole is slightly larger than the outer diameter of the end of the retrieval shaft 21, and the inner diameter of the second mounting hole is slightly larger than the outer diameter of the end of the dispensing shaft 31, so as to reduce the rotational friction of the retrieval shaft 21 and the dispensing shaft 31 while limiting their installation.

[0058] In some embodiments, the ribbon dispensing roll 3 includes a dispensing shaft 31 and a mating structure 32. The dispensing shaft 31 is rotatably mounted on the housing 1 about its axial direction. The mating structure 32 extends along the axial direction of the ribbon dispensing roll 3 to one side of the dispensing shaft 31 and is integrally formed with the dispensing shaft 31. The housing 1 includes a limiting structure 13, and the mating structure 32 is used to cooperate with the limiting structure 13 to limit the reverse rotation of the ribbon dispensing roll 3. It can be understood that the dispensing shaft 31 is rotatably mounted on the housing 1 about its axial direction, and the ribbon 500 is wound around the dispensing shaft 31. During the actual operation of the ribbon housing 100, the ribbon 500 is dispensed when the dispensing shaft 31 rotates in the forward direction, ensuring that the ribbon 500 can move along a predetermined path.

[0059] Please refer to Figure 4 The ribbon reel assembly 3 also includes a mating structure 32, which works in conjunction with the limiting structure 13 of the housing 1. When the dispensing shaft 31 rotates in the forward direction, the limiting structure 13 does not affect the movement of the dispensing shaft 31. When the dispensing shaft 31 rotates in the reverse direction, the mating structure 32 and the limiting structure 13 work together to restrict the dispensing shaft 31 from rotating in the reverse direction. This effectively reduces the risk of the ribbon 500 accidentally rewinding during the printing process, helps maintain the tension of the ribbon 500 within a reasonable range, reduces the risk of ribbon breakage, and ensures the stability and consistency of the printing process, reducing printing defects caused by the ribbon 500 loosening or rewinding.

[0060] In addition, the cooperating structure 32 extends along the axial direction of the dispensing carbon ribbon roll 3, which facilitates the cooperation with the limiting structure 13 to realize the limiting function. Furthermore, the integrated design of the cooperating structure 32 and the dispensing shaft 31 can reduce the number of corresponding parts, reduce assembly difficulty and production costs, and further improve the reliability and durability of the carbon ribbon box 100.

[0061] Furthermore, in this embodiment of the application, the box body 1 includes a first shell 11 and a second shell 12, and the limiting structure 13 is located in the fourth mounting part 122 of the second shell 12 for mounting corresponding to the dispensing shaft 31.

[0062] It is understood that in some embodiments, the limiting structure 13 includes a sensing component and a driving component 5. The sensing component monitors the position of the mating structure 32, and the movement of the driving component 5 is combined to achieve a precise limiting method, thereby further improving the efficiency and quality of printing.

[0063] Please refer to Figure 4 and Figure 5 The mating structure 32 has a plurality of first mating surfaces 32a and a plurality of second mating surfaces 32b alternately arranged circumferentially along the dispensing shaft 31. The second mating surfaces 32b are arranged at an angle to the first mating surfaces 32a. Each second mating surface 32b and one of the adjacent first mating surfaces 32a enclose a mating space. The limiting structure 13 includes an elastic element 131. The elastic element 131 has a telescoping amount along the axial direction of the dispensing shaft 31. The end of the elastic element 131 is located in one of the mating spaces and abuts against the first mating surface 32a. When the elastic element 131 contacts the second mating surface 32b, the dispensing carbon ribbon roll 3 is limited to rotate in the opposite direction.

[0064] Specifically, when the dispensing shaft 31 rotates in the forward direction, the end of the elastic element 131 abuts against the first mating surface 32a and moves along the first mating surface 32a. As the elastic element 131 moves, it gradually compresses from its initial state. When the end of the elastic element 131 moves into the mating space, it returns to its initial state. During the continued forward rotation, the end of the elastic element 131 continues to abut against the next first mating surface 32a. It can be understood that during the forward rotation of the dispensing shaft 31, the end of the elastic element 131 will not abut against the second mating surface 32b. However, when the dispensing shaft 31 rotates in the reverse direction, the end of the elastic element 131 will contact the second mating surface 32b. During the continuous reverse rotation, the force applied by the second mating surface 32b to the elastic element 131 is perpendicular to the extension and retraction direction of the elastic element 131, and cannot drive the elastic element 131 to move in the extension and retraction direction. The elastic element 131 is used to prevent the dispensing shaft 31 from rotating in the reverse direction, thereby limiting the reverse rotation of the dispensing carbon ribbon roll 3.

[0065] Understandably, limiting the rotation direction of the ribbon roll 3 using the above method effectively reduces the risk of ribbon 500 rewinding, ensuring that ribbon 500 maintains the correct tension and movement path during printing, thus improving the stability and consistency of the printing effect. Furthermore, the cooperation between structure 32 and limiting structure 13 provides strong stability and reliability, maintaining good limiting performance under various working conditions.

[0066] Specifically, the mating structure 32 is located on the inner periphery of the dispensing shaft 31, and the limiting structure 13 includes an elastic member 131. At least a portion of the elastic member 131 extends into the interior of the dispensing shaft 31 and mates with the mating structure 32. The design is compact and efficient, and the limiting function can be achieved without increasing the volume of the cartridge 1, which is beneficial to the miniaturization design of the ribbon cartridge 100.

[0067] Further, please continue to refer to Figure 4 Along the direction of forward rotation of the carbon ribbon roll 3, the first mating surface 32a is an inclined surface that slopes away from the second mating surface 32b towards the side away from the issuing shaft 31. The second mating surface 32b is a plane parallel to the axial direction of the carbon ribbon roll 3, and in the direction of forward rotation of the carbon ribbon roll 3, the second mating surface 32b is located in front of the first mating surface 32a.

[0068] In embodiments of this application, the second mating surface 32b and the axial direction of the dispensing ribbon roll 3 are parallel, the first mating surface 32a and the second mating surface 32b form an angle, the first mating surface 32a is inclined, and the first mating surface 32a is inclined along the end away from the dispensing shaft 31. In the axial direction of the dispensing ribbon roll 3, the first mating surface 32a has a high point near the end of the dispensing shaft 31 and a low point away from the end of the dispensing shaft 31. In some embodiments, when the dispensing ribbon roll 3 rotates in the forward direction, the end of the elastic member 131 and the first mating surface 32a... When the elastic element 131 is in contact with the low point, during rotation, the end of the elastic element 131 moves from the low point to the high point. At this time, the first mating surface 32a provides the elastic element 131 with a support force in the direction perpendicular to the first mating surface 32a. The support force has a component along the axial direction of the dispensing shaft 31, so it can drive the elastic element 131 to contract until the end of the elastic element 131 contacts the high point of the first mating surface 32a. After passing the high point, the elastic force of the elastic element 131 is released, which can ensure that the end of the elastic element 131 moves to the low point of the next first mating surface 32a without obstruction.

[0069] Correspondingly, in some embodiments, when the ribbon roll 3 is rotated in the reverse direction, the end of the elastic member 131 moves from the high point to the low point along the first mating surface 32a until the end of the elastic member 131 and the second mating surface 32b come into contact. Since the second mating surface 32b is parallel to the axial direction of the ribbon roll 3, that is, parallel to the extension and contraction direction of the elastic member 131, when the rotation continues, the force applied by the second mating surface 32b to the end of the elastic member 131 is perpendicular to the axial direction of the ribbon roll 3. This force has no component force along the axial direction of the ribbon roll 3, so it cannot drive the elastic member 131 to contract, so as to achieve the effect of limiting the reverse rotation of the ribbon roll 3.

[0070] In some embodiments, the ribbon delivery roll 3 includes a mating structure 32, and the mating structure 32 includes a first mating surface 32a and a second mating surface 32b to simplify the structure of the ribbon delivery roll 3; in other embodiments, the ribbon delivery roll 3 includes a plurality of mating structures 32 radially spaced along the delivery shaft 31, each mating structure 32 including a first mating surface 32a and a second mating surface 32b, wherein the second mating surface 32b of one mating structure 32 and the first mating surface 32a of another adjacent mating structure 32 enclose a mating space, and the plurality of mating structures 32 can achieve a better limiting effect, and can respond quickly when the delivery shaft 31 rotates in the opposite direction to achieve the limiting function.

[0071] In addition, the elastic element 131 includes a spring 1311 and a protrusion 1312 mounted on the free end of the spring 1311. The protrusion 1312 is used to cooperate with the mating structure 32 to achieve a limiting effect. In some embodiments, the number of protrusions 1312 is set to multiple, and the multiple protrusions 1312 correspond to the mating space between multiple mating structures 32. The locking effect between the multiple protrusions 1312 and the multiple mating structures 32 is better, thereby improving the reliability of the limiting effect.

[0072] Please refer to Figure 4 The recycled ribbon roll 2 includes a recycling shaft 21 and two reels 22. The recycling shaft 21 is rotatably mounted on the housing 1. Along the axial direction of the recycling shaft 21, the two reels 22 are respectively located at opposite ends of the recycling shaft 21. The two reels 22 and the recycling shaft 21 are used to define the winding space for the recycled ribbon 500. Specifically, during the winding process of the recycled ribbon roll 2, the recycling shaft 21 rotates, guiding the ribbon 500 to wind onto the recycling shaft 21. The two reels 22 are used to define the winding space, evenly winding the ribbon 500 into the winding space. The two reels 22 can stably guide the ribbon 500 to be neatly wound on the recycling shaft 21, avoiding the ribbon 500 from becoming loose or disordered. This not only improves the winding efficiency of the ribbon 500 but also extends the service life of the ribbon 500.

[0073] Please refer to Figure 6 The ribbon cartridge 100 also includes a damping structure 4, which is installed in the cartridge body 1 and located between the ribbon dispensing roll 3 and the printing space 1a. The damping structure 4 is used to abut against the ribbon 500 to tension the ribbon 500 located in the printing space 1a. In the embodiments of this application, the specific design of the damping structure 4 can take various forms, such as using a spring 1311, a rubber pad, or a friction wheel. Different damping structures 4 can be selected according to actual needs and application scenarios, and this application does not limit this.

[0074] Specifically, the damping structure 4 is located between the ribbon delivery roll 3 and the printing space 1a to ensure that the ribbon 500 is tensioned by the damping structure 4 before entering the printing space 1a. This layout is beneficial to the force exerted by the damping structure 4 on the ribbon 500, thereby ensuring that it can maintain appropriate tension during the printing process.

[0075] In practical applications, when the ribbon 500 is released from the ribbon reel 3 and passes through the damping structure 4, the damping structure 4 applies a certain resistance to the ribbon 500, so that it is tensioned before entering the printing space 1a. Furthermore, by adjusting the position or angle of the damping structure 4, the frictional force of the damping structure 4 on the ribbon 500 can be changed, thereby achieving the effect of controlling the tension of the ribbon 500, ensuring that the ribbon 500 maintains an appropriate tension during the printing process, and preventing it from becoming loose or overstretched.

[0076] In addition, the damping structure 4 can also guide the ribbon 500, ensuring that the ribbon 500 can move along a certain path, reducing its shaking or deviation during movement, and ensuring its position accuracy within the printing space 1a, thereby improving the printing quality. The damping structure 4 can also provide a certain buffering effect to absorb the minor vibrations or impacts that may occur to the ribbon 500 during transmission, thereby improving the overall stability of the ribbon cartridge 100.

[0077] Please continue to refer to Figure 6 The housing 1 also includes a guide structure 14, which includes a first guide post 141 and a second guide post 142. The ribbon 500 released by the ribbon reel 3 passes around the outer periphery of both the first guide post 141 and the second guide post 142 in sequence before entering the printing space 1a. The damping structure 4 is located on the side of the first guide post 141 facing away from the ribbon reel 3 and is used to abut against the ribbon 500 that is wrapped around the outer periphery of the first guide post 141. The second guide post 142 is located on the side of the first guide post 141 facing the ribbon reel 3 and is used to contact the surface of the ribbon 500 facing away from the first guide post 141. Understandably, the first guide post 141 is used to guide the carbon ribbon 500 from the dispensing carbon ribbon roll 3 to the damping structure 4. The first guide post 141 and the damping structure 4 are spaced apart. The first guide post 141 pulls the carbon ribbon 500 to fit against the damping structure 4 to ensure that the carbon ribbon 500 can be tensioned. The second guide post 142 is used to pull the carbon ribbon 500 to move in a direction away from the damping structure 4 to avoid the carbon ribbon 500 and the edge of the damping structure 4 to contact each other and reduce direct contact between the carbon ribbon 500 and the edge of the damping structure 4. In some embodiments, the edge of the damping structure 4 is relatively sharp. This setting can effectively reduce the risk of the carbon ribbon 500 being cut.

[0078] In the embodiments of this application, the first guide post 141 and the second guide post 142 have smooth surfaces, thereby reducing friction of the carbon ribbon 500 during its movement around its periphery, reducing the risk of carbon ribbon 500 breakage, and extending the service life of the first guide post 141 and the second guide post 142.

[0079] Specifically, the guide structure 14 also includes multiple auxiliary guide posts 143. In some embodiments, the housing 1 has two opposing openings, and some of the auxiliary guide posts 143 are disposed at the two openings to guide the ribbon 500 out or into the openings without contacting them. Other auxiliary guide posts 143 are disposed on the periphery of the recycled ribbon roll 2 to guide the ribbon 500 to the recycled ribbon roll 2. By providing multiple auxiliary guide posts 143, the movement path of the ribbon 500 can be precisely controlled, ensuring that the ribbon 500 does not affect the normal operation of other components during its movement.

[0080] In some embodiments, the first guide post 141 is rotatably mounted on the housing 1; and / or, the second guide post 142 is rotatably mounted on the housing 1. In some embodiments of this application, the first guide post 141 is rotatably mounted on the housing 1 about its axis. This arrangement reduces friction when the ribbon 500 moves around the first guide post 141, facilitating smooth operation of the ribbon 500. In other embodiments, the second guide post 142 is rotatably mounted on the housing 1 about its axis. This arrangement also reduces friction when the ribbon 500 moves around the second guide post 142, facilitating smooth operation of the ribbon 500. Furthermore, in some embodiments, both the first guide post 141 and the second guide post 142 are rotatably mounted on the housing 1 about their axes. The first guide post 141 and the second guide post 142 can better guide the ribbon 500 into the printing space 1a. This arrangement not only improves the transmission efficiency of the ribbon 500 but also reduces wear on the ribbon 500 and the first and second guide posts 141 and 142 caused by friction, thus extending the service life of the ribbon 500 and the first and second guide posts 141 and 142.

[0081] Furthermore, in some embodiments, the damping structure 4 includes a damping spring 41 and a flexible patch 42. The damping spring 41 is mounted on the housing 1, and the flexible patch 42 is integrally formed with the damping spring 41 and contacts the ribbon 500. In this embodiment, the housing 1 has a mounting portion corresponding to the damping spring 41. One end of the damping spring 41 is inserted into the mounting portion, and the other end extends to the first guide post 141 and is close to the ribbon 500. The flexible patch 42 is located on the side of the damping spring 41 close to the ribbon 500 and contacts the ribbon 500. The surface of the flexible patch 42 has a certain coefficient of friction and is relatively soft, which can provide frictional resistance in close contact with the ribbon 500 without damaging the ribbon 500. This ensures that the ribbon 500 is in a taut state before entering the printing space 1a, which not only improves the printing quality and reduces the risk of tape jamming, but also protects the ribbon 500 and extends its service life.

[0082] The flexible patch 42 includes any one of flexible structures such as a velvet sheet, a rubber sheet, or a silicone sheet. This application does not limit the types of flexible structures, as long as they can achieve the above-mentioned technical effects.

[0083] Secondly, please refer to Figures 7 to 9 This application provides a printer 1000, including a host 200, a printing roller 300, a heated printhead 400, and the aforementioned ribbon cartridge 100. The printing roller 300 is mounted on the host 200, and the heated printhead 400 is mounted on the host 200 and disposed corresponding to the printing roller 300. The heated printhead 400 has a heating surface that is close to the printing roller 300. The ribbon cartridge 100 is mounted on the host 200, and at least a portion of the heated printhead 400 is disposed in a printing space 1a. The ribbon 500 in the printing space 1a is located in the space between the printing roller 300 and the heated printhead 400.

[0084] It is understood that the printer 1000 includes the ribbon cartridge 100 described above. The specific structure of the ribbon cartridge 100 is as described in the above embodiments. Since the printer 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0085] Furthermore, in this embodiment, the host 200 is used to accommodate various components of the printer 1000, such as the printing roller 300, the heated printhead 400, and the ribbon cartridge 100. The printing roller 300 is installed on the host 200 and is responsible for contacting the wire tube or other printing media, and driving the relevant printing media forward by rotating it. The heated printhead 400 is also installed on the host 200 and has a heating surface. The heating surface of the heated printhead 400 is close to the printing roller 300 and the heated printhead 400 is located in the printing space 1a so that the ribbon 500 can be placed between the heated printhead 400 and the printing roller 300. In the printing space 1a, the ribbon 500 is heated by the heated printhead 400, and the ink or coating on it is transferred to the corresponding printing media to achieve the printing effect on the printing media.

[0086] Please refer to Figure 8 The host 200 includes a drive assembly 5, which includes a first drive motor and a first drive shaft 51. The first drive motor is connected to the first drive shaft 51, and the first drive shaft 51 is connected to the recycling ribbon roll 2. The first drive motor drives the first drive shaft 51 to rotate, thereby causing the recycling ribbon roll 2 to rotate around the first drive shaft 51. In this embodiment, the first drive motor is installed on the host 200 to provide power for the rotation of the first drive shaft 51. Correspondingly, the housing 1 is provided with a first mounting hole for the recycling ribbon roll 2. The recycling ribbon roll 2 includes a recycling shaft 21. The first drive shaft 51 passes through the first mounting hole and is inserted into the recycling shaft 21. The rotation of the first drive shaft 51 drives the rotation of the recycling shaft 21. It is understood that, in the embodiments of this application, when the recycled carbon ribbon roll 2 winds up the carbon ribbon 500, the movement of the carbon ribbon 500 can drive the unwinding carbon ribbon roll 3 to unwind the carbon ribbon 500. It is only necessary to drive the recycled carbon ribbon roll 2 to rotate through the first drive shaft 51, thereby achieving synchronous driving of the unwinding and winding of the carbon ribbon 500 and reducing the loosening or excessive stretching of the carbon ribbon 500.

[0087] Please refer to Figure 4 , Figure 8 and Figure 9 The recycling carbon tape roll 2 includes a recycling shaft 21 and a plurality of ratchet protrusions 23. The plurality of ratchet protrusions 23 are spaced apart along the circumference of the recycling shaft 21. The first drive shaft 51 is provided with a plurality of spaced mating flanges 511 around its outer circumference. The mating flanges 511 abut against the ratchet protrusions 23 in the circumference of the recycling shaft 21 as the first drive shaft 51 rotates, so as to drive the rotation of the recycling shaft 21.

[0088] Specifically, multiple protrusions 23 are spaced apart inside the recovery shaft 21. The first drive shaft 51 extends into the recovery shaft 21, and multiple spaced mating flanges 511 arranged around the first drive shaft 51 extend into the space between two adjacent protrusions 23. When the first drive motor drives the first drive shaft 51 to rotate, the first drive shaft 51 and the mating flanges 511 rotate synchronously, and a mating flange 511 abuts against the side of a protrusion 23 during rotation, thereby driving the protrusion 23 and the recovery shaft 21 connected thereto to rotate, so as to realize the synchronous rotation of the first drive shaft 51 and the recovery shaft 21. It can be understood that the recovery shaft 21 and the first drive shaft 51 adopt a plug-in mating method, which makes it easy to install the ribbon box 100 in the corresponding position of the main unit 200. The drive assembly 5 can drive the smooth movement of the ribbon 500 in the ribbon box 100 by driving the operation of the recovery ribbon roll 2. The setup is simple and convenient for subsequent maintenance and adjustment.

[0089] Further, please refer to Figure 9 Along the circumference of the recovery shaft 21, the distance between any two adjacent ratchet protrusions 23 is X1, and the thickness at the connection between the mating flange 511 and the first drive shaft 51 is X2, where 1mm ≤ X1 - X2 ≤ 6mm. It should be noted that the distance between any two ratchet protrusions 23 is defined as the distance between two adjacent sides of any two ratchet protrusions 23, which is X1. Correspondingly, the thickness at the connection between the mating flange 511 and the first drive shaft 51 is defined as the distance between the two sides of the mating flange 511 along the circumference of the first drive shaft 51, which is X2. X1 - X2 can be understood as the range of movement of the mating flange 511 between any two ratchet protrusions 23, which is between 1mm and 6mm.

[0090] With this configuration, when the recovery shaft 21 is assembled with the first drive shaft 51, it is not completely fixed to the first drive shaft 51, but has a certain rotation space relative to the first drive shaft 51. The rotation distance is between 1mm and 6mm. When the carbon ribbon 500 is pulled by an external force, the recovery shaft 21 can rotate relative to the first drive shaft 51 to release a certain length of carbon ribbon 500, providing some leeway when the carbon ribbon 500 is driven by an external force, thereby reducing the risk of carbon ribbon 500 breaking.

[0091] Please refer to Figure 4Each ratchet 23 has a guide surface 23a, which is an inclined surface facing away from the end of the retrieval shaft 21. It is understood that, to facilitate the installation and engagement between the first drive shaft 51 and the retrieval shaft 21, each ratchet 23 is provided with a guide surface 23a. When the first drive shaft 51 extends into the inner side of the retrieval shaft 21, the mating flange 511 can slide more smoothly between the ratchet 23s, reducing installation difficulty. Furthermore, the design of the guide surface 23a ensures that even with slight misalignment during installation, the mating flange 511 can gradually slide into the correct position via the guide surface 23a, ensuring smooth engagement and further reducing installation difficulty.

[0092] In other embodiments, please refer to Figure 7 and Figure 8 The drive assembly 5 also includes a second drive motor and a second drive shaft 52. The second drive motor is connected to the second drive shaft 52, and the second drive shaft 52 is connected to the ribbon delivery roll 3. The second drive motor drives the second drive shaft 52 to rotate, thereby causing the ribbon delivery roll 3 to rotate around the second drive shaft 52. It is understood that in some embodiments, the drive assembly 5 includes a first drive motor, a second drive motor, a first drive shaft 51, and a second drive shaft 52. The first drive motor and the first drive shaft 51 drive the recycle ribbon roll 2 to wind up the ribbon 500, while the second drive motor and the second drive shaft 52 drive the ribbon delivery roll 3 to unwind the ribbon 500. This dual-drive approach achieves precise control of the ribbon delivery roll 3 and the recycle ribbon roll 2. This dual-drive design ensures that the ribbon delivery and rewinding speeds are matched, preventing the ribbon 500 from becoming loose or overstretched, effectively reducing the risk of ribbon breakage, and improving print quality.
