Description

Technical Field

[0001] This application belongs to the field of printing equipment technology, specifically relating to a ribbon conveying device and a printer. Background Technology

[0002] During printer operation, there is a risk of the ribbon running out, which can cause the printer to malfunction. Utility Model Content

[0003] This application provides a carbon ribbon conveying device, which aims to at least partially mitigate the risk of carbon ribbon extinction.

[0004] In a first aspect of this application, a ribbon conveying device is provided, comprising: a ribbon; a drive member having a rotatable output portion, the output portion rotating about a first direction or the opposite direction of the first direction; a ribbon delivery reel assembly drivenly connected to the output portion of the drive member; and a ribbon take-up reel assembly drivenly connected to the output portion of the drive member, the ribbon being wound around the ribbon delivery reel assembly and the ribbon take-up reel assembly; wherein, when the output portion rotates about the first direction, the drive member drives the ribbon take-up reel to rotate actively, and the ribbon take-up reel drives the ribbon delivery reel to rotate passively via the ribbon; when the output portion rotates in the opposite direction of the first direction, the drive member drives the ribbon delivery reel to rotate actively, and the ribbon delivery reel drives the ribbon take-up reel to rotate passively via the ribbon.

[0005] The ribbon transport device provided in this application has a rotatable output section for the drive unit. Both the ribbon take-up reel assembly and the ribbon take-up reel assembly are driveably connected to the output section of the drive unit. Therefore, when the printer is performing a paper output task, the drive unit can actively rotate the ribbon take-up reel assembly, which in turn drives the ribbon delivery reel assembly to rotate passively via the ribbon. Conversely, when the printer is performing a paper output task, the drive unit actively rotates the ribbon delivery reel assembly, which in turn drives the ribbon take-up reel assembly to rotate passively via the ribbon. In other words, this application uses a single drive unit to complete both the paper return and output actions of the printer. During paper return or output, one of the ribbon delivery reel assembly and the ribbon take-up reel assembly rotates actively, while the other rotates passively. Therefore, the rotation speeds of the two assemblies are always kept consistent, improving the situation where ribbon breaks occur due to differences in their rotation speeds, thus ensuring the printer functions normally.

[0061] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0062] In related technologies, consumable cartridges include ribbon dispensing reels and ribbon recycling reels. The ribbon dispensing reel dispenses new ribbons, and the ribbon recycling reel recycles used ribbons. When the consumable cartridge is placed in the printer body, it is necessary to recycle or dispense ribbons.

[0063] The relevant technology uses two motors to drive the ribbon delivery and take-up reels separately. However, this solution has the following technical problem: if the speed of one motor is unstable, ribbon breakage may occur. For example, when the printer outputs paper, both the ribbon delivery and take-up reels rotate clockwise at the same speed. If the speed of the ribbon delivery motor is unstable, for example, if the ribbon delivery reel rotates slightly slower than the take-up reel, the take-up reel will pull on the ribbon at the end of the delivery reel, thus risking ribbon breakage. Similarly, when rewinding paper, both the ribbon delivery and take-up reels rotate counterclockwise at the same speed. If the speed of the ribbon take-up motor is unstable, for example, if the take-up reel rotates slightly slower than the delivery reel, the delivery reel will pull on the ribbon at the end of the take-up reel, also risking ribbon breakage. If the printer experiences ribbon breakage, it will affect print quality and printing efficiency, thereby impacting the user experience.

[0064] Based on the above-mentioned technical problems, this application provides a ribbon conveying device, which mainly uses a motor to simultaneously drive the ribbon delivery reel and the ribbon take-up reel to rotate in order to complete the paper return and paper output actions. During paper return or paper output, one of the ribbon delivery reel and the ribbon take-up reel rotates actively and the other rotates passively, so that the rotation speed of the two can always be kept consistent, thereby avoiding the above-mentioned situation of ribbon breakage.

[0065] Based on the above concept, in the first aspect of this application, a carbon belt conveyor 10 is provided. Figure 1 A schematic diagram of the structure of a ribbon conveyor 10 according to one or more embodiments of this application is shown. (In conjunction with...) Figure 1 The ribbon conveyor 10 includes a ribbon 110, a drive unit 120, a ribbon delivery reel assembly 130, and a ribbon take-up reel assembly 140. The drive unit 120 has a rotatable output section 121 that rotates about a first direction or the opposite direction. The ribbon delivery reel assembly 130 is driven by the output section 121 of the drive unit 120. The ribbon take-up reel assembly 140 is driven by the output section 121 of the drive unit 120. The ribbon 110 is wound around the ribbon delivery reel assembly 130. 0 and ribbon take-up reel assembly 140; wherein, when the output unit 121 rotates about a first direction, the drive member 120 drives the ribbon take-up reel 141 to rotate actively, and the ribbon take-up reel 141 drives the ribbon dispensing reel 131 to rotate passively through the ribbon 110; when the output unit 121 rotates in the opposite direction about the first direction, the drive member 120 drives the ribbon dispensing reel 131 to rotate actively, and the ribbon dispensing reel 131 drives the ribbon take-up reel 141 to rotate passively through the ribbon 110.

[0066] The ribbon conveying device 10 provided in this application has a rotatable output section 121 for the drive member 120. Both the ribbon take-up reel assembly 140 and the ribbon take-up reel assembly 140 are connected to the output section 121 of the drive member 120. Therefore, when the printer performs a paper output task, the drive member 120 can drive the ribbon take-up reel assembly 140 to rotate actively, and the ribbon take-up reel assembly 140 drives the ribbon delivery reel assembly 130 to rotate passively through the ribbon 110. When the printer performs a paper output task, the drive member 120 drives the ribbon delivery reel assembly 130 to rotate actively, and the ribbon delivery reel assembly 130 drives the ribbon take-up reel assembly 140 to rotate passively through the ribbon 110. In other words, this application uses a drive unit 120 to complete the paper feeding and paper output actions of the printer according to the instructions. When feeding or outputting paper, one of the ribbon delivery reel assembly 130 and the ribbon take-up reel assembly 140 rotates actively and the other rotates passively. Therefore, the rotation speed of the two can always be kept consistent, which improves the situation of ribbon 110 being interrupted due to the difference in the rotation speed of the two, so that the printer can work normally.

[0067] Figure 2 A schematic diagram is shown of the ribbon transport device 10 assembled on the printer body 150. The printer body 150 has a receiving groove 151 with its opening facing upwards. When the ribbon transport device 10 is assembled on the printer body 150, at least a portion of the ribbon transport device 10 is located within the consumable cartridge 160, which is detachably connected to the printer body 150 and can be removed from the printer body 150 from bottom to top. For ease of description, the vertical, horizontal, and front-back directions are defined, where vertical refers to the height of the printer, front-back refers to the paper output direction, and horizontal refers to the horizontal direction perpendicular to the front-back direction. The specific details of the ribbon transport device 10 will now be further described with reference to the accompanying drawings.

[0068] Figure 3 It shows Figure 2 A partial schematic diagram of the printer body 150 shown. (Combined with...) Figure 3In some embodiments, the drive component 120 is mounted on the printer body 150 and is hidden below the bottom of the receiving slot 151. When the consumable cartridge 160 is removed from the printer body 150, the drive component 120 remains inside the printer body 150 and is not exposed outside the printer body 150, thus keeping the bottom of the receiving slot 151 on the printer body 150 clean to a certain extent. In addition, the bottom of the receiving slot 151 is also provided with two through holes 152 for the bottom ends of the ribbon delivery reel assembly 130 and the ribbon take-up reel assembly 140 to pass through, respectively, for transmission connection with the drive component 120. In other embodiments, the drive component 120 may also be mounted inside the bottom of the consumable cartridge 160, and the drive component 120 is removed together with the consumable cartridge 160, which also keeps the bottom of the receiving slot 151 on the printer body 150 clean.

[0069] Figure 4 It shows Figure 1 A structural diagram from another perspective. Combined with... Figure 4 The drive unit 120 includes a drive motor 122, a reduction gear set 123 and a drive gear 124 connected in sequence. The drive motor 122 drives the drive gear 124 to rotate at a suitable speed through a set of reduction gear set 123. The drive gear 124 is configured as the output part 121 of the drive unit 120.

[0070] Figure 5 A schematic diagram showing the assembly of the drive gear 124 with the ribbon dispensing reel assembly 130 and the ribbon take-up reel assembly 140 is provided. Figure 5 The drive gear 124 meshes with both the ribbon delivery reel assembly 130 and the ribbon take-up reel assembly 140, and is located in the area between them. Thus, one of the ribbon delivery reel assembly 130 and the ribbon take-up reel assembly 140 can be driven to rotate actively, while the other rotates passively. In a specific implementation, the ribbon delivery reel assembly 130 and the ribbon take-up reel assembly 140 are arranged opposite each other, and the central axis of the drive gear 124 is located on the perpendicular bisector of the plane containing the central axes of the ribbon delivery reel assembly 130 and the ribbon take-up reel assembly 140.

[0071] Figure 6 A schematic diagram of the carbon ribbon recycling reel assembly 140 is shown. (Combined with...) Figure 6 The ribbon recycling reel assembly 140 includes a ribbon recycling reel 141 and a ribbon recycling drive 142. The ribbon recycling drive 142 is connected to the output unit 121. The ribbon recycling reel 141 and the ribbon recycling drive 142 are connected and have a driving state and a non-driving state. Figure 7 A schematic diagram of the structure of the ribbon dispensing reel assembly 130 is shown, combined with Figure 7The ribbon delivery reel assembly 130 includes a ribbon delivery reel 131 and a ribbon delivery drive 132. The ribbon delivery drive 132 is driveably connected to the output unit 121. The ribbon delivery reel 131 and the ribbon delivery drive 132 are connected and have a driven state and a non-driven state. When the output unit 121 rotates about a first direction, the ribbon take-up reel 141 and the ribbon take-up drive 142 are in the driven state, and the ribbon delivery reel 131 and the ribbon delivery drive 132 are in the non-driven state. When the output unit 121 rotates in the opposite direction about the first direction, the ribbon delivery reel 131 and the ribbon delivery drive 132 are in the driven state, and the ribbon take-up reel 141 and the ribbon take-up drive 142 are in the non-driven state. Furthermore, when the output unit 121 rotates about the first direction or rotates in the opposite direction about the first direction, the output unit 121 is driven by both the ribbon take-up drive 142 and the ribbon delivery drive 132.

[0072] That is, by setting up the ribbon recovery drive 142 and the ribbon dispensing drive 132, this application enables the ribbon recovery drive 142 to be in a driving state with the ribbon recovery reel 141 and the ribbon recovery reel 141 both being driven, while the ribbon dispensing drive 132 to be in a non-driving state with the ribbon dispensing reel 131; or, the ribbon dispensing drive 132 to be in a driving state with the ribbon dispensing reel 131 and the ribbon dispensing reel 131, while the ribbon recovery drive 142 to be in a non-driving state with the ribbon recovery reel 141. This allows the reel in the driving state to rotate actively, while the reel in the non-driving state is passively rotated by the ribbon 110, thus keeping their rotation speeds consistent and preventing the ribbon 110 from disconnecting as mentioned above.

[0073] Specifically, when the printer performs the paper return task, the drive gear is connected to both the ribbon dispensing drive 132 and the ribbon take-up drive 142. Both the ribbon dispensing drive 132 and the ribbon take-up drive 142 are driven to rotate by the drive gear. At this time, the ribbon dispensing drive 132 and the ribbon dispensing reel 131 are in a driving state, so that the rotating ribbon dispensing drive 132 drives the ribbon dispensing reel 131 to rotate. The ribbon take-up drive 142 and the ribbon take-up reel 141 are in a non-driving state. The rotating ribbon take-up drive 142 cannot drive the ribbon take-up reel 141 to rotate. The ribbon take-up reel 141 can only drive the ribbon 110 to rotate through the rotating ribbon dispensing reel 131, thereby causing the ribbon take-up reel 141 to rotate passively.

[0074] When the printer is performing a paper output task, the drive gear is connected to both the ribbon dispensing drive 132 and the ribbon take-up drive 142. Both the ribbon dispensing drive 132 and the ribbon take-up drive 142 are driven to rotate by the drive gear. At this time, the ribbon take-up drive 142 and the ribbon take-up reel 141 are in a driving state, so that the rotating ribbon take-up drive 142 drives the ribbon take-up reel 141 to rotate. When the ribbon dispensing drive 132 and the ribbon dispensing reel 131 are in a non-driving state, the rotating ribbon dispensing drive 132 cannot drive the ribbon dispensing reel 131 to rotate. The ribbon dispensing reel 131 can only drive the ribbon 110 to rotate through the rotating ribbon take-up reel 141, thereby causing the ribbon dispensing reel 131 to rotate passively.

[0075] Combination Figure 6 In some embodiments, the ribbon recovery drive 142 includes a first one-way clutch 1421, which is drive-connected to the output section 121. The ribbon recovery reel 141 is connected to the first one-way clutch 1421 and has a driven state and a non-driven state. Figure 7 The carbon ribbon delivery drive 132 includes a second one-way clutch 1321, which is connected to the output section 121. The carbon ribbon delivery reel 131 is connected to the second one-way clutch 1321 and has a driving state and a non-driving state. Both the first one-way clutch 1421 and the second one-way clutch 1321 can transmit torque in one direction and rotate freely in the opposite direction.

[0076] The first one-way clutch 1421 and the second one-way clutch 1321 have the same structure. Taking the first one-way clutch 1421 as an example, the specific structure of the first one-way clutch 1421 will be further described. The second one-way clutch 1321 can be referred to the relevant description of the first one-way clutch 1421. This application will not repeat it here.

[0077] Figure 8 A schematic diagram of the first one-way clutch 1421 is shown. (Combined with...) Figure 8 In some embodiments, the first one-way clutch 1421 includes a first one-way bearing 14211, which is sleeved on the ribbon delivery reel 131 and is drively connected to the output section 121. When the output section 121 of the drive member 120 rotates about a first direction, both first one-way bearings 14211 on the ribbon take-up reel 141 and the ribbon delivery reel 131 are driven to rotate by the drive member 120. One of the first one-way bearings 14211 transmits torque to the reel in the driving state to drive the reel to rotate actively; the other first one-way bearing 14211 rotates freely, and the reel in the non-driving state, along with the other first one-way bearing 14211, rotates passively under the drive of the ribbon 110.

[0078] Combination Figure 8 In some embodiments, the first one-way clutch 1421 further includes a transmission gear 14212, which meshes with the output unit 121. The transmission gear 14212 is sleeved on the carbon belt take-up reel 141, and is coupled with the first one-way bearing 14211 so that the transmission gear 14212 and the first one-way bearing 14211 can be synchronously driven by the output unit 121. That is, this application transmits the power of the drive member 120 to the two first one-way bearings 14211 through the transmission gear 14212. In other embodiments, the outer ring of the first one-way bearing 14211 is provided with a gear for meshing with the drive gear, which can also achieve the purpose of transmitting the power of the drive member 120 to the two first one-way bearings 14211.

[0079] Figure 9 An exploded schematic diagram of the first one-way clutch 1421 is shown. (Combined with...) Figure 8 as well as Figure 9 Both the transmission gear 14212 and the first one-way bearing 14211 are sleeved on the carbon belt feed reel 131. One of the transmission gear 14212 and the first one-way bearing 14211 is provided with a positioning groove 14213, and the other is provided with a positioning protrusion 14214. The positioning protrusion 14214 is adapted to be disposed in the positioning groove 14213, thereby enabling the transmission gear 14212 and the first one-way bearing 14211 to be relatively fixed. Under the condition that the transmission gear 14212 is driven by the drive gear to rotate, the first one-way bearing 14211 can rotate synchronously with the transmission gear 14212.

[0080] In some embodiments, the radial depth of the positioning groove 14213 engaging with the positioning protrusion 14214 can be 0.5mm-1.5mm. This configuration can prevent the transmission gear 14212 from disengaging from the first one-way bearing 14211, thus preventing the transmission gear 14212 from driving the first one-way bearing 14211.

[0081] Combination Figure 8 as well as Figure 9One of the end faces of the transmission gear 14212 and the first one-way bearing 14211 is provided with a first receiving groove 14215, and at least a portion of the other end face is adapted to be disposed in the first receiving groove 14215. The gap between the two is less than the radial depth of the positioning groove 14213 and the positioning protrusion 14214 that mates. This arrangement ensures that at least a portion of the positioning protrusion 14214 is always adapted to be disposed in the positioning groove 14213, thereby further preventing the transmission gear 14212 and the first one-way bearing 14211 from disengaging, which would prevent the transmission gear 14212 from driving the first one-way bearing 14211.

[0082] Combination Figure 8 as well as Figure 9 In specific implementation, both the transmission gear 14212 and the first one-way bearing 14211 are located at the end of the carbon belt feed reel 131. The first one-way bearing 14211 is located at the outer end of the transmission gear 14212. The end face of the transmission gear 14212 facing the first one-way bearing 14211 is provided with a first receiving groove 14215. The side wall of the first receiving groove 14215 is provided with a positioning protrusion 14214. The first one-way bearing 14211 is adapted to be disposed in the first receiving groove 14215. The outer peripheral surface of the first one-way bearing 14211 is provided with a positioning groove 14213. The positioning protrusion 14214 is adapted to be disposed in the positioning groove 14213. In other embodiments, the first receiving groove 14215 may be formed at the end of the outer ring of the first one-way bearing 14211 facing the transmission gear 14212, a portion of the transmission gear 14212 is disposed in the first receiving groove 14215, the positioning protrusion 14214 is disposed on the first one-way bearing 14211, and the positioning groove 14213 is disposed on the transmission gear 14212; in addition, multiple sets of positioning protrusions 14214 and positioning grooves 14213 may be provided in a compatible manner, and this application does not limit this.

[0083] It should be noted that in other embodiments, the first one-way clutch 1421 and the second one-way clutch 1321 may also be a ratchet and pawl mechanism or other structures, and this application does not limit them.

[0084] The ribbon dispensing reel assembly 130 and the ribbon recycling reel assembly 140 of this application have roughly the same structure. Taking the ribbon recycling reel assembly 140 as an example, the specific details of the ribbon recycling reel assembly 140 will be further described. For the specific structure of the ribbon dispensing reel assembly 130, please refer to the relevant description of the ribbon recycling reel assembly 140. This application will not elaborate on this.

[0085] Figure 10 It shows Figure 6 A schematic diagram of the explosion. Combined with... Figure 10In some embodiments, the ribbon reel assembly 140 includes a first shaft 1411, a second shaft 1412, and a buffer 1413. The first shaft 1411 is connected to the output section 121, and the second shaft 1412 is spaced at least a portion of the circumferential surface of the first shaft 1411. The buffer 1413 connects the first shaft 1411 and the second shaft 1412. When the drive unit 120 is operating, the drive unit 120 drives the first shaft 1411 to rotate, and the first shaft 1411 drives the second shaft 1412 to rotate via the buffer 1413. Since the ribbon 110 is wound around the outer circumference of the second shaft 1412, and since the first shaft 1411 is connected to the second shaft 1412 through the buffer 1413, when the drive member 120 drives the first shaft 1411 to rotate, the second shaft 1412 can be smoothly accelerated until the rotation speed of the second shaft 1412 and the first shaft 1411 is consistent. This reduces sudden tension changes and avoids the problem of the second shaft 1412 being momentarily accelerated due to the rigid connection between the second shaft 1412 and the first shaft 1411, which would cause the ribbon 110 to be overstretched. This reduces the risk of ribbon 110 breakage, reduces ribbon 110 wear, extends the service life of ribbon 110, and improves print quality.

[0086] Figure 11 An assembly diagram of the first shaft 1411, the second shaft 1412, and the buffer member 1413 is shown. Figure 11 In some embodiments, the buffer 1413 is a torsion spring, which is sleeved on the first shaft 1411 and has a connecting end 14131, which is connected to the second shaft 1412. When the first shaft 1411 is driven to rotate, the torsion spring rotates synchronously, and then drives the second shaft 1412 to rotate through the rotation of the connecting end 14131. In specific implementation, the first one-way clutch 1421 is connected to the bottom end of the first shaft 1411, and the buffer 1413 is sleeved on the top end of the first shaft 1411. For example, when the first one-way clutch 1421 rotates counterclockwise, when the first one-way clutch 1421 and the first shaft 1411 are in a driving state, the first one-way clutch 1421 can sequentially drive the first shaft 1411 and the second shaft 1412 to rotate. When the first one-way clutch 1421 rotates clockwise, when the first one-way clutch 1421 and the first shaft 1411 are in a non-driving state, the first one-way clutch 1421 cannot drive the first shaft 1411 and the second shaft 1412 to rotate.

[0087] Figure 12 It shows Figure 11 A schematic diagram of the explosion. Combined with... Figure 11 as well as Figure 12The first shaft 1411 has a protrusion 1414 on its circumferential surface, which protrudes beyond the circumferential surface of the first shaft 1411. A torsion spring is sleeved on the protrusion 1414. The inner wall of the second shaft 1412 has a second receiving groove 14151 that matches the protrusion 1414. The side wall of the second receiving groove 14151 has a retaining groove 1416, and the connecting end 14131 of the torsion spring is engaged in the retaining groove 1416. By adding the protrusion 1414 to the circumferential surface of the first shaft 1411, the distance between the torsion spring and the second shaft 1412 can be reduced, thus preventing the connecting end 14131 of the torsion spring from disengaging from the retaining groove 1416 when the torsion spring deforms, thereby preventing the second shaft 1412 from rotating under the drive of the first shaft 1411. In a specific implementation, the protrusion 1414 is an annular structure disposed on the circumferential surface of the first shaft 1411 near its bottom end, while the second receiving groove 14151 is formed at the bottom end of the second shaft 1412. Of course, in other embodiments, the protrusion 1414 may also be located on the circumferential surface of the first shaft 1411 near its top end, while the second receiving groove 14151 is correspondingly formed at the top end of the second shaft 1412.

[0088] Figure 13 It shows Figure 6 A frontal view diagram. Combined with... Figure 13 The bottom end of the first shaft 1411 protrudes beyond the bottom end of the second shaft 1412. The transmission gear 14212 and the first one-way bearing 14211 are sequentially connected to the bottom end of the first shaft 1411. When the consumable box 160 is assembled on the printer body 150, the first one-way clutch 1421 formed by the transmission gear 14212 and the first one-way bearing 14211 is located below the bottom of the receiving groove 151. By limiting the bottom of the receiving groove 151, the first one-way clutch 1421 formed by the transmission gear 14212 and the first one-way bearing 14211 can be prevented from shifting upwards towards the first shaft 1411.

[0089] Combination Figure 13 The carbon ribbon recycling reel assembly 140 also includes a first limiting member 143, which is connected to a first shaft 1411. A second shaft 1412 and a first one-way clutch 1421 are sequentially positioned close to the first limiting member 143. The first one-way clutch 1421 abuts against at least a portion of the first limiting member 143 to restrict the first one-way clutch 1421, which is composed of a transmission gear 14212 and a first one-way bearing 14211, from shifting downwards from the first shaft 1411. Furthermore, the first limiting member 143 is connected to the bottom end of the first shaft 1411 and is located below the bottom of the receiving groove 151. This arrangement ensures that the first one-way clutch 1421 is positioned between the bottom of the receiving groove 151 and the first limiting member 143, guaranteeing that the first one-way clutch 1421 is in its designated working position.

[0090] Figure 14 This diagram shows the assembly of the first one-way clutch 1421 and the first limiting member 143 on the first shaft 1411. Figure 15 A structural schematic diagram of the first limiting member 143 is shown. (Combined with...) Figure 14 as well as Figure 15 At least a portion of the circumferential surface of the first shaft 1411 is provided with a first mounting groove 1417. A first limiting member 143 is engaged in the first mounting groove 1417 to connect the first limiting member 143 to the first shaft 1411. The first limiting member 143 has a first limiting portion 1431 protruding from the circumferential surface of the first shaft 1411. A first one-way clutch 1421 abuts against the first limiting portion 1431 to limit the position of the first one-way clutch 1421. In a specific implementation, the first mounting groove 1417 is an annular groove that wraps around the circumferential surface of the bottom end of the first shaft 1411. In other embodiments, the first mounting groove 1417 can also be an arc-shaped groove, as long as it ensures that a portion of the first limiting member 143 is embedded in the first mounting groove 1417.

[0091] Combination Figure 14 as well as Figure 15 The first limiting member 143 is a plate-shaped structure. A first mounting hole 1432 is provided in the middle of the first limiting member 143, and the first shaft body 1411 is adapted to pass through the first mounting hole 1432. A first through-hole 1433 is provided on the circumferential surface of the first limiting member 143, and the first through-hole 1433 communicates with the first mounting hole 1432. When assembling the first limiting member 143 onto the first shaft body 1411, the first limiting member 143 can be inserted into the first mounting groove 1417 on the first shaft body 1411 from the first through-hole, so that the first shaft body 1411 is adapted to pass through the first mounting hole 1432.

[0092] Combination Figure 15 In some embodiments, the inner wall of the first mounting hole 1432 is provided with at least one first deformation groove 1434 to improve the deformation capability of the first limiting member 143, making it easier for the first limiting member 143 to be assembled onto the first shaft 1411. Specifically, two first deformation grooves 1434 are provided, located on the inner wall of the first mounting hole 1432 opposite to the first through hole opening. Of course, one or three first deformation grooves 1434 may also be provided; this application does not limit this.

[0093] Figure 16 An assembly diagram of the first shaft 1411 and the second shaft 1412 is shown. (Combined with...) Figure 16The carbon ribbon recycling reel assembly 140 also includes a second limiting member 144, which is connected to the first shaft 1411 and disposed on the side of the second shaft 1412 away from the first one-way clutch 1421. The second shaft 1412 abuts against at least a portion of the second limiting member 144 to allow the second shaft 1412 to rotate between the second limiting member 144 and the bottom of the consumable box 160.

[0094] Figure 17 A schematic diagram of the second limiting member 144 is shown. (Combined with...) Figure 16 as well as Figure 17 At least a portion of the circumferential surface of the first shaft 1411 is provided with a second mounting groove 1419. A second limiting member 144 is engaged in the second mounting groove 1419 to connect the second limiting member 144 to the first shaft 1411. The second limiting member 144 has a second limiting portion 1441 protruding from the circumferential surface of the first shaft 1411. The second shaft 1412 abuts against the second limiting portion 1441 to limit the position of the second shaft 1412. In a specific implementation, the second mounting groove 1419 is an annular groove that wraps around the circumferential surface of the top end of the first shaft 1411. In other embodiments, the second mounting groove 1419 can also be an arc-shaped groove, as long as it ensures that a portion of the second limiting member 144 is embedded in the second mounting groove.

[0095] Combination Figure 17 The second limiting member 144 is a plate-shaped structure. A second mounting hole 1442 is provided in the middle of the second limiting member 144, through which the first shaft 1411 is fitted. A second through-hole 1443 is provided on the circumferential surface of the second limiting member 144, communicating with the second mounting hole 1442. When assembling the second limiting member 144 onto the second shaft 1412, the second limiting member 144 can be inserted into the second mounting groove on the first shaft 1411 from the second through-hole, so that the first shaft 1411 fits through the second mounting hole 1442.

[0096] Combination Figure 17 The inner wall of the second mounting hole 1442 is provided with at least one second deformation groove 1444 to improve the deformation capability of the second limiting member 144, making it easier for the second limiting member 144 to be assembled onto the first shaft 1411. In a specific implementation, two second deformation grooves 1444 are provided, and the two second deformation grooves 1444 are provided on the inner wall of the second mounting hole 1442 opposite to the second through hole opening. Of course, one or three second deformation grooves 1444 can also be provided, and this application does not limit this.

[0097] Figure 18 An exploded view of the ribbon recycling reel assembly 140 is shown, combined with... Figure 18The ribbon recycling reel assembly 140 also includes a ribbon recycling sleeve 145, which is spaced within the ribbon recycling reel 141. The inner circumferential surface of the ribbon recycling sleeve 145 is provided with one or more first protruding ridges 1451 at intervals, and the outer circumferential surface of the ribbon recycling reel 141 is provided with one or more second protruding ridges 1419 at intervals. The first protruding ridges 1451 and the second protruding ridges 1419 abut against each other. The ribbon recovery reel 141 includes the aforementioned first shaft 1411 and second shaft 1412. A second protruding rib 1419 is disposed on the outer circumferential surface of the second shaft 1412. In some embodiments, three second protruding ribs 1419 are equally spaced, and three first protruding ribs 1451 are also equally spaced. The ribbon 110 is wound around the ribbon recovery sleeve 145. When the ribbon recovery reel 141 is driven to rotate, the second protruding ribs 1419 and the first protruding ribs 1451 abut against each other to drive the ribbon recovery sleeve 145 to rotate, thereby conveying the ribbon 110 wound around the ribbon recovery sleeve 145. In other embodiments, one, two, or four first protruding ribs 1451 and second protruding ribs 1419 may be provided; this application limits this group.

[0098] Figure 19 An exploded view of the ribbon dispensing reel assembly 130 is shown. (Combined with...) Figure 19 The ribbon delivery reel assembly 130 includes a ribbon delivery reel 131 and a ribbon delivery sleeve 133. The ribbon delivery sleeve 133 is fitted onto the ribbon delivery reel 131 with a gap. The inner circumferential surface of the ribbon delivery sleeve 133 is provided with one or more third protruding ribs 1331 at intervals, and the outer circumferential surface of the ribbon delivery reel 131 is provided with one or more fourth protruding ribs 1311 at intervals. The third protruding ribs 1331 and the fourth protruding ribs 1311 abut against each other. The ribbon dispensing reel 131 also includes the aforementioned first and second shafts. A fourth protrusion 1311 is disposed on the outer circumferential surface of the second shaft. Three fourth protrusions 1311 are evenly spaced, and three third protrusions 1331 are also evenly spaced. The ribbon 110 is wound around the ribbon dispensing sleeve 133. When the ribbon dispensing reel 131 is driven to rotate, the third protrusions 1331 and fourth protrusions 1311 abut against each other to drive the ribbon dispensing sleeve 133 to rotate, thereby conveying the ribbon 110 wound around the ribbon dispensing sleeve 133. In other embodiments, there may be one, two, or four third protrusions 1331 and fourth protrusions 1311, etc. This application limits this group.

[0099] Based on the above-described ribbon conveyor 10, in a second aspect of this application, this application also provides a printer that includes the above-described ribbon conveyor 10.

[0100] A printer equipped with the above-mentioned ribbon transport device 10 can keep the rotation speed of the ribbon take-up reel assembly 140 and the ribbon take-up reel assembly 140 consistent at all times, thereby improving the situation where the ribbon 110 is pulled and broken due to the difference in rotation speed between the two, so that the printer can work normally.

[0101] As described above, the printer of this application also includes a printer body 150 and a consumable cartridge 160, the consumable cartridge 160 being detachably mounted on the printer body 150; wherein, the drive unit 120 is connected to the printer body 150, and at least a portion of the ribbon delivery reel assembly 130 and the ribbon take-up reel assembly 140 are located within the consumable cartridge 160.

[0102] Figure 20 A schematic diagram of the printer body 150 equipped with a consumable cartridge 160 is shown. Figure 21 A schematic diagram of the printer body 150 without the consumable cartridge 160 is shown. (Combined with...) Figure 20 as well as Figure 21 The printer body 150 has a receiving groove 151. The drive unit 120 is located below the bottom of the receiving groove 151. The bottom end of the ribbon delivery reel 131 of the ribbon delivery reel assembly 130 and the ribbon take-up reel 141 of the ribbon take-up reel assembly 140 are both located at the bottom of the receiving groove 151. Correspondingly, the first one-way clutch 1421 and the second one-way clutch are also located at the bottom of the receiving groove 151. The top end of the ribbon delivery reel 131 and the top end of the ribbon take-up reel 141 of the ribbon take-up reel assembly 140 both pass through the bottom of the receiving groove 151 and are located inside the receiving groove 151. The ribbon delivery sleeve 133 of the ribbon delivery reel assembly 130 and the ribbon take-up sleeve 145 of the ribbon take-up reel assembly 140 are both located inside the consumable box 160. The bottom of the consumable box 160... The consumable cartridge 160 is provided with through holes for the ribbon delivery reel 131 and the ribbon take-up reel 141 to pass through. When the consumable cartridge 160 is assembled into the receiving slot 151 of the printer body 150, the ribbon delivery reel 131 and the ribbon take-up reel 141 pass through the corresponding through holes at the bottom of the consumable cartridge 160 and are located inside the consumable cartridge 160. The ribbon delivery reel 131 is located inside the ribbon delivery sleeve 133 and is connected to the ribbon delivery sleeve 133. The ribbon take-up reel 141 is located inside the ribbon take-up sleeve 145 and is connected to the ribbon take-up sleeve 145. Thus, under the drive of the drive unit 120, the ribbon delivery reel 131 drives the ribbon delivery sleeve 133 to rotate, or the ribbon take-up reel 141 drives the ribbon take-up sleeve 145 to rotate, so as to perform the paper output and paper return actions of the printer. With the consumable cartridge 160 removed from the printer body 150, the ribbon delivery bushing 133 and the ribbon recycling bushing 145 are removed simultaneously with the consumable cartridge 160.
