[0022] In some embodiments, the dispensing assembly has a first centerline about which it rotates to dispense the ribbon, the first centerline being located on the side of the first end away from the paper outlet.
[0023] In some embodiments, the dispensing assembly has a first centerline and is configured to rotate about the first centerline to dispense the ribbon, and the consumable cartridge further includes a recycling assembly having a second centerline and being configured to rotate about the second centerline to recycle the ribbon;
[0024] Wherein, the distance between the second axis and the first axis in the length direction of the consumable box is a, and a satisfies: 2.5mm≤a≤6mm.

[0055] 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.
[0056] In existing technology, the consumable cartridge contains a label paper roll and a ribbon reel. Unused ribbon is dispensed from the ribbon reel and then printed via the print head. Unused label paper is also printed via the print head after exiting the label paper roll. However, in this technology, there is a significant amount of ribbon wastage when only a small amount remains.
[0057] It should be noted that, like a magnetic tape, when printing down to the last bit of ribbon, the remaining ribbon will detach from the spindle of the ribbon reel. Because the ribbon is very thin, it will wrinkle once it detaches from the spindle, and wrinkled ribbon cannot be used. This results in the waste of the last bit of ribbon.
[0058] To resolve the above technical issues, please refer to Figure 1 This application provides a printer 100, which includes a printer body 10, a printhead 20, and a consumable cartridge 30. The printer body 10 has a receiving cavity 101. The printhead 20 is disposed on the printer body 10 and located in the receiving cavity 101. The consumable cartridge 30 can be assembled in the receiving cavity 101. The consumable cartridge 30 includes a clearance structure 34, which allows the printhead 20 to pass through the clearance structure 34. The consumable cartridge 30 can reduce the waste of the ribbon 321.
[0059] Please see Figures 1 to 3 This application provides a consumable cartridge 30, which includes a cartridge body 31, a dispensing assembly 32, a paper roll assembly 33, and a clearance structure 34. The cartridge body 31 has a paper outlet 310. The dispensing assembly 32 is disposed in the cartridge body 31 and is used to dispense ribbon 321. The paper roll assembly 33 is disposed in the cartridge body 31 and is used to dispense label paper 331. The clearance structure 34 is disposed in the cartridge body 31 and has a receiving groove 340 for accommodating the print head 20 of the printer 100. Furthermore, the side of the avoidance structure 34 away from the dispensing component 32 is provided with an opening 340a that communicates with the receiving groove 340. The portion of the avoidance structure 34 that forms the opening 340a includes a first end 341 and a second end 342. The first end 341, the second end 342 and the paper outlet 310 are distributed in sequence. During printing, the ribbon 321 and the label paper 331 pass through the first end 341, the second end 342 and the paper outlet 310 in sequence. Moreover, the dispensing component 32 is closer to the avoidance structure 34 than the paper roll component 33.
[0060] It should be noted that, Figure 2 The X-axis direction of the seed is the width direction of the consumable box 30. Figure 2 The Y-axis direction of the seed is the length direction of the consumable box 30. Figure 2 The Z-axis direction of the consumable box is the height direction of 30.
[0061] Optionally, the box body 31 has a cuboid-like structure and has an assembly cavity and a paper outlet 310 communicating with the assembly cavity. The dispensing component 32 and the paper roll assembly 33 are both disposed in the assembly cavity and connected to the box body 31. The dispensing component 32 includes a first spool 322 and a carbon ribbon 321 wound on the first spool 322. The first spool 322 is disposed in the assembly cavity and rotatably connected to the box body 31, so that the first spool 322 can rotate to dispense the carbon ribbon 321 wound on it. The paper roll assembly 33 includes a paper roll 322 and a label paper 331 wound on the paper roll 322. The paper roll 322 is disposed in the assembly cavity and rotatably connected to the box body 31, so that the paper roll 322 can rotate to dispense the label paper 331 wound on it. The dispensed carbon ribbon 321 and label paper 331 can both extend out of the box body 31 from the paper outlet 310.
[0062] The clearance structure 34 can be disposed on the box body 31, and the clearance structure 34 has a receiving groove 340. The receiving groove 340 can penetrate through the first side of the box body 31 along the axial direction of the first scroll 322 to form a receiving opening on the first side of the box body 31. The first side is the side of the box body 31 facing the receiving cavity 101 during the process of assembling the consumable box 30 into the receiving cavity 101. Thus, when the consumable box 30 is assembled into the receiving cavity 101, the print head 20 can be inserted into the receiving groove 340 from the receiving opening, so that the consumable box 30 can be easily assembled with the print head 20. Of course, the receiving groove 340 can also penetrate through the opposite two sides of the box body 31 along the axial direction of the first scroll 322.
[0063] The clearance structure 34 also has an opening 340a communicating with the receiving groove 340. When the consumable box 30 is assembled in the receiving cavity 101, the opening 340a is located on the side of the clearance structure 34 away from the dispensing component 32, and the opening 340a can expose the print head 20. The part of the clearance structure 34 that forms the opening 340a includes a first end 341 and a second end 342. The first end 341, the second end 342 and the paper outlet 310 are distributed in sequence. During printing, the ribbon 321 and the label paper 331 pass through the first end 341, the opening 340a and the second end 342 in sequence, and the paper outlet 310 extends out. The printing roller on the printer 100 can extend into the receiving groove 340 from the opening 340a, and the printing roller can push the ribbon 321 and the label paper 331 to contact the print head 20, thereby enabling the printing of the label paper 331.
[0064] When the ribbon 321 on the dispensing assembly 32 is dispensed, the last part of the ribbon 321 will detach from the first reel 322. Since the ribbon 321 is very thin, it will lose tension once it detaches from the first reel 322, causing it to wrinkle. The wrinkled ribbon 321 cannot be used. Therefore, when the ribbon 321 on the dispensing assembly 32 is dispensed, the ribbon 321 between the first reel 322 and the first end 341 will be wasted. By placing the dispensing assembly 32 closer to the clearance structure 34 relative to the paper roll assembly 33, or in other words, by placing the dispensing assembly 32 closer to the first end 341 relative to the paper roll assembly 33, the distance between the dispensing assembly 32 and the first end 341 will be minimized. Thus, when the ribbon 321 on the dispensing assembly 32 is dispensed, the length of the ribbon 321 between the first reel 322 and the first end 341 will be the shortest, reducing damage to the ribbon 321.
[0065] It should be noted that the label paper 331 is different from the ribbon 321. The label paper 331 is more rigid than the ribbon 321. Even if the last bit of the label paper 331 comes off the roll 322, the label paper 331 will not become wrinkled and can be used up. Therefore, setting the roll assembly 33 away from the avoidance structure 34 will not increase the waste of the label paper 331.
[0066] Please see Figure 4 and Figure 5 In some embodiments, the avoidance structure 34 includes a first sidewall 343 disposed on the housing 31, and the carbon ribbon 321 dispensed by the dispensing component 32 passes sequentially through the first sidewall 343, the first end 341 and the second end 342. The dispensing component 32 has a first position 320 for dispensing the carbon ribbon 321, which is located on the side of the first sidewall 343 near the paper outlet 310.
[0067] Optionally, the first sidewall 343 may be located within the assembly cavity of the housing 31, and the first sidewall 343 has a first plane. During printing, the ribbon 321 dispensed by the dispensing component 32 passes sequentially through the first plane, the first end 341, and the second end 342 of the first sidewall 343. The first sidewall 343 is the first component that the ribbon 321 contacts after leaving the dispensing component 32. The first plane of the first sidewall 343 can provide a platform for the ribbon 321 to be flattened, so that the ribbon 321 can remain in an unfolded state before passing the first end 341. This can prevent the ribbon 321 from wrinkling during the dispensing process, thereby ensuring that the printer 100 has a good printing effect.
[0068] It should be noted that during the dispensing of the ribbon 321, the position where the ribbon 321 leaves the dispensing component 32 is the first position 320. The first position 320 is located on the side of the first sidewall 343 near the paper outlet 310. According to the dispensing trajectory of the ribbon 321, the ribbon 321 needs to make a turn before it can move onto the first sidewall 343, so that the first sidewall 343 can support the ribbon 321. Thus, the first sidewall 343 can provide a force for the ribbon 321 to spread it out and prevent the ribbon 321 from wrinkling.
[0069] However, if the first position 320 is located on the side of the first sidewall 343 away from the paper outlet 310, according to the delivery trajectory of the carbon ribbon 321, the carbon ribbon 321 will move in a straight line to the first sidewall 343. The first sidewall 343 cannot provide a force for the carbon ribbon 321, that is, the tension force on the carbon ribbon 321 will be reduced, which will make the carbon ribbon 321 more prone to wrinkling and increase the waste of the carbon ribbon 321.
[0070] Please see Figure 4 and Figure 5 In some embodiments, the first position 320 is located on the side of the dispensing component 32 closer to the avoidance structure 34.
[0071] Optionally, the first position 320 is set on the side of the dispensing component 32 near the avoidance structure 34, so that only a small part of the dispensing component 32 needs to be set near the avoidance structure 34, so that the first position 320 is located on the side of the first sidewall 343 near the paper outlet 310. This allows the dispensing component 32 to maintain a certain distance from the printhead 20, thereby reducing the impact of the heat generated by the printhead 20 on the ribbon 321 on the dispensing component 32 when the printhead 20 heats up.
[0072] It should be noted that if the first position 320 is set on the side of the dispensing component 32 close to the avoidance structure 34, in order to make the first position 320 located on the side of the first sidewall 343 close to the paper outlet 310, the entire dispensing component 32 needs to be set close to the avoidance structure 34, which shortens the distance between the dispensing component 32 and the print head 20. When the print head 20 heats up, the heat generated by the print head 20 will be more easily transferred to the ribbon 321 of the dispensing component 32, which will accelerate the aging of the ribbon 321 and make the ribbon 321 unusable, increasing the waste of the ribbon 321.
[0073] Please see Figure 4 and Figure 5 In some embodiments, the avoidance structure 34 further includes a guide portion 344 disposed on the first sidewall 343 and protruding relative to the first sidewall 343, the guide portion 344 being used to support the carbon ribbon 321.
[0074] Optionally, the guide portion 344 is disposed on the first plane of the first sidewall 343, and the guide portion 344 protrudes relative to the first plane. When the ribbon 321 passes through the first plane, the guide portion 344 can support the ribbon 321, so that the guide portion 344 can provide support for the ribbon 321, which can increase the tension force on the ribbon 321, thereby allowing the ribbon 321 to spread out better and improve the printing effect. In addition, the side of the guide portion 344 that supports the ribbon 321 can be an arc surface, which can further reduce the wear of the ribbon 321.
[0075] Please see Figure 5 In some embodiments, the ribbon 321 contacts the first sidewall 343 after passing through the guide portion 344 and has a first contact position 3430. The connection between the first contact position 3430 and the first position 320 is located on the side of the guide portion 344 near the paper outlet 310.
[0076] Understandably, after passing through the guide section 344, the ribbon 321 will contact the first plane. The position where the ribbon 321 first contacts the first plane is defined as the first contact position 3430. The line connecting the first contact position 3430 and the first position 320 is located on the side of the guide section 344 near the paper outlet 310. This ensures that the line connecting the first position 320 and the position where the guide section 344 supports the ribbon 321 intersects with the line connecting the first contact position 3430 and the position where the guide section 344 supports the ribbon 321. Therefore, the ribbon 321 can unfold on the first plane of the first sidewall 343 while reducing the contact area between the ribbon 321 and the first plane, thereby reducing wear between the ribbon 321 and the first plane and minimizing ribbon 321 consumption.
[0077] Please see Figure 4 and Figure 5 In some embodiments, the avoidance structure 34 further includes a second sidewall 345 and a third sidewall 346. The second sidewall 345 is disposed on the housing 31 and is angled and connected to the first sidewall 343. The second sidewall 345 has a first end 341. The third sidewall 346 is disposed on the housing 31 and is located on the side of the first sidewall 343 near the paper outlet 310. The third sidewall 346 has a second end 342, and an opening 340a is formed between the second end 342 and the first end 341. The first sidewall 343, the second sidewall 345, and the third sidewall 346 together define a receiving groove 340, and the opening 340a is used for the ribbon 321 to contact the print head 20.
[0078] Optionally, the second sidewall 345 may have a second plane, which may be set at an angle to and connected to the first plane. The dispensed ribbon 321 may pass through the first plane and the second plane in sequence. Since the first plane and the second plane are set at an angle, the ribbon 321 can be provided with tension when it passes through the first plane and the second plane, so that the ribbon 321 can be further spread out, thereby improving the printing effect.
[0079] The second sidewall 345 has a first end 341, and the third sidewall 346 has a second end 342. An opening 340a is formed between the second end 342 and the first end 341. The print head 20 is accommodated in a receiving groove 340 defined by the first sidewall 343, the second sidewall 345, and the third sidewall 346. During printing, the printing roller can extend from the opening 340a into the receiving groove 340 to squeeze the ribbon 321 and the label paper 331 into contact with the print head 20, thereby achieving printing.
[0080] The third sidewall 346 may have a third plane, which may be set at an angle to the second plane. During the printing process, the ribbon 321 may pass through the first plane, the second plane and the third plane in sequence. The ribbon 321 is used for printing after passing through the first plane, and the printed ribbon 321 is recycled after passing through the third plane. Since the third plane is set at an angle to the second plane, the printed ribbon 321 will be further spread out when passing through the third plane, which can facilitate the recycling of the ribbon 321.
[0081] Please see Figure 4 In some embodiments, the dispensing assembly 32 has a first axis N1, which is used to rotate about the first axis N1 to dispense the ribbon 321. The first axis N1 is located on the side of the first end 341 away from the paper outlet 310.
[0082] Optionally, the first axis line N1 is set on the side of the first end 341 away from the paper outlet 310, so that the first position 320 of the dispensing component 32 dispensing the carbon ribbon 321 can be closer to the first end 341, that is, the distance between the first position 320 and the first end 341 can be reduced, thereby reducing the length of the carbon ribbon 321 between the first position 320 and the first end 341, and thus reducing the waste of the carbon ribbon 321.
[0083] If the first axis line N1 is set on the side of the first end 341 near the paper outlet 310, the first position 320 of the dispensing component 32 dispensing the ribbon 321 will be farther away from the first end 341, which will result in a longer distance between the first position 320 and the first end 341. As a result, the length of the ribbon 321 between the first position 320 and the first end 341 will increase, which will increase the waste of the ribbon 321.
[0084] Please see Figure 4 and Figure 5 In some embodiments, the dispensing component 32 has a first axis N1 and is used to rotate around the first axis N1 to dispense the ribbon 321. The consumable box 30 also includes a recycling component 35, which has a second axis N2 and is used to rotate around the second axis N2 to recycle the ribbon 321. The distance between the second axis N2 and the first axis N1 in the length direction of the consumable box 30 is a, where a satisfies: 2.5mm ≤ a ≤ 6mm.
[0085] Optionally, both the dispensing component 32 and the recycling component 35 are rotatably mounted on the housing 31, and the dispensing component 32 and the recycling component 35 are located on the same side of the clearance structure 34. The dispensing component 32 and the recycling component 35 are arranged adjacent to each other, and the first axis N1 and the second axis N2 are arranged parallel to each other. The dispensing component 32 rotates around the first axis N1 in a first direction to dispense the carbon ribbon 321, and the recycling component 35 rotates around the second axis N2 in a first direction to recycle the printed carbon ribbon 321.
[0086] Figure 5 The Y-axis direction is the length direction of the consumable box 30. The distance between the second axis N2 and the first axis N1 in the length direction of the consumable box 30 is 'a'. If a > 6 mm, the dispensing component 32 and the recycling component 35 will be too far apart along the length direction of the consumable box 30, which will increase the overall volume of the consumable box 30. If a < 2.5 mm, the dispensing component 32 and the recycling component 35 will be close to being flush, and the space occupied by the dispensing component 32 and the recycling component 35 in the width direction of the consumable box 30 will be more, which will also increase the overall volume of the consumable box 30. Therefore, when a satisfies 2.5 mm ≤ a ≤ 6 mm, the space inside the box 31 can be reasonably utilized to install the dispensing component 32 and the recycling component 35, thereby reducing the overall volume of the consumable box 30.
[0087] Please see Figure 4 and Figure 5 In some embodiments, the distance between the second axis N2 and the first axis N1 in the width direction of the consumable box 30 is b, where b satisfies: 16mm≤b≤30mm.
[0088] Optionally, Figure 5 In the diagram, the Y-axis direction represents the width of the consumable cartridge 30. If b < 16mm, the distance between the dispensing component 32 and the recycling component 35 will be too small. During the recycling process of the ribbon 321, the printed carbon on the recycling component 35 may rub against the ribbon 321 on the dispensing component 32, increasing the waste of the ribbon 321. If b > 30mm, the distance between the dispensing component 32 and the recycling component 35 will be too large. Although this can prevent the ribbon 321 from being worn, it will increase the overall size of the consumable cartridge 30. Therefore, when b satisfies 16mm ≤ b ≤ 30mm, it can both prevent the ribbon 321 from being worn and prevent the consumable cartridge 30 from becoming too large.
[0089] Please see Figure 4 and Figure 5In some embodiments, the dispensing component 32 has a first position 320 for dispensing carbon ribbon 321. The dispensing component 32 dispenses carbon ribbon 321 from the first position 320 to the first end 341. There is a first trajectory line between the first position 320 and the first end 341. The first trajectory line is the movement trajectory of the carbon ribbon 321. The length of the first trajectory line is c, and c satisfies: 10mm≤c≤30mm.
[0090] Optionally, during the process of dispensing the ribbon 321, the first position 320 is the position where the ribbon 321 leaves the dispensing component 32, and the ribbon 321 moves from the first position 320 to the first end 341. There is a first trajectory line between the first position 320 and the first end 341, and the length of the first trajectory line can be equal to the length of the ribbon 321 between the first position 320 and the first end 341.
[0091] In this embodiment, the first trajectory line is approximately a curve. The ribbon 321 bends and extends to the first end 341 after passing the first sidewall 343. If c < 10 mm, the dispensing component 32 will be closer to the avoidance structure 34. More specifically, the dispensing component 32 will be closer to the print head 20. This makes it easier for the print head 20 to transfer heat to the ribbon 321 on the dispensing component 32 when it is heated, which will accelerate the aging of the ribbon 321 and cause unnecessary waste. If c > 30 mm, the length of the ribbon 321 between the first position 320 and the first end 341 will be too long. When the ribbon 321 is used to its last bit, the amount of ribbon 321 wasted will increase. Therefore, when c satisfies 10 mm ≤ c ≤ 30 mm, the waste of ribbon 321 can be further reduced.
[0092] Please see Figure 4 and Figure 5 In some embodiments, the consumable box 30 further includes a partition 36 disposed on the box body 31, with the dispensing component 32 and the roll paper component 33 located on opposite sides of the partition 36.
[0093] Optionally, the partition 36 can be disposed between the dispensing component 32 and the roll paper assembly 33, and the dispensing component 32 and the recycling component 35 are located on the same side of the partition 36. By dispensing the partition 36, the roll paper assembly 33 and the dispensing component 32 can be separated, so that the roll paper assembly 33 will not interfere with the dispensing component 32 when dispensing the label paper 331.
[0094] More specifically, during the printing process, the label paper 331 may experience paper slippage. When slippage occurs, the outer layer of the label paper 331 roll will unravel. Without the obstruction of the partition 36, the unraveled label paper 331 will rub against the ribbon 321 on the dispensing component 32, causing the ribbon 321 to wrinkle or become unusable, thus increasing the waste of the ribbon 321.
[0095] Please see Figure 4 and Figure 5 In some embodiments, the consumable box 30 further includes a guide plate 37 disposed on the box body 31 and connected to the partition 36. The guide plate 37 is located on the side of the dispensing assembly 32 away from the paper outlet 310. The guide plate 37 is used to guide the label paper 331 from the roll paper assembly 33 to the first end 341, and the label paper 331 and the ribbon 321 are respectively located on opposite sides of the guide plate 37.
[0096] Optionally, the guide plate 37 can be an arc-shaped plate, and one end of the guide plate 37 is connected to the partition plate 36. The other end of the guide plate 37 is bent and extended in a direction close to the first end 341. The guide plate 37 is located on the side of the dispensing assembly 32 away from the paper outlet 310. There is a gap between the guide plate 37 and the first side wall 343. After the label paper 331 leaves the roll assembly 33, the label paper 331 can move along the guide plate 37 to the first end 341. After the ribbon 321 leaves the dispensing assembly 32, the ribbon 321 can move along the first side wall 343. The ribbon 321 can pass through the gap between the guide plate 37 and the first side wall 343 and contact the label paper 331 at a position close to the first end 341, so that the ribbon 321 and the label paper 331 can contact the print head 20 at the opening 340a to achieve printing.
[0097] The guide plate 37 can separate the label paper 331 from the ribbon 321 before it approaches the first end 341, thereby preventing the label paper 331 from contacting the ribbon 321 and rubbing against it as soon as it leaves the roll assembly 33. This reduces the friction on the ribbon 321 and decreases the likelihood of the ribbon 321 wrinkling.
[0098] Please see Figure 4 and Figure 5 In some embodiments, the dispensing component 32 includes a spool 322 and a ribbon roll 323. The spool 322 is rotatably connected to the box body 31. The ribbon roll 323 is wound around the spool 322. The outermost layer of the ribbon roll 323 has a gap d between it and the partition 36, the guide plate 37 and the clearance structure 34. The gap d satisfies: 1.5mm≤d≤10mm.
[0099] Optionally, the spool 322 is the same component as the first spool 322 mentioned above. The carbon ribbon 321 is wound around the axis of the spool 322 in sequence to form the carbon ribbon roll 323. The outermost layer of the carbon ribbon roll 323 has a gap d between it and the partition 36, the guide plate 37 and the clearance structure 34, so as to prevent friction between the outermost layer of the carbon ribbon roll 323 and the partition 36, the guide plate 37 and the clearance structure 34, and reduce the wear of the carbon ribbon 321.
[0100] If d < 1.5 mm, the distance between the outermost layer of the ribbon roll 323 and the partition 36, guide plate 37, and clearance structure 34 will be too small. During printing, the dispensing assembly 32 may shake, and this shaking may cause the outermost layer of the ribbon roll 323 to rub against one of these components, resulting in wear on the ribbon 321. If d > 10 mm, although the distance between the outermost layer of the ribbon roll 323 and the partition 36, guide plate 37, and clearance structure 34 will be large enough that even when the dispensing assembly 32 shakes, the outermost layer of the ribbon roll 323 will not rub against any of these components, but this will increase the overall volume of the consumable box 30.
[0101] Therefore, when d satisfies 1.5mm≤d≤10mm, it can prevent the outermost layer of the carbon ribbon roll 323 from rubbing against one of the partition 36, the guide plate 37, and the avoidance structure 34, without causing the overall volume of the consumable box 30 to increase too much.
[0102] Please see Figure 4 and Figure 5 In some embodiments, a first centerline N4 is provided between the first end 341 and the second end 342, and the paper roll assembly 33 has a third axis N3 for rotating about the third axis N3 to dispense label paper 331. The third axis N3 is located on the side of the first centerline N4 away from the paper outlet 310.
[0103] Optionally, the vertical distance between the first center line N4 and the first end 341 is equal to the vertical distance between the first center line N4 and the second end 342, so that the first center line N4 is located in the middle position between the first end 341 and the second end 342. The third axis line N3 is set on the side of the first center line N4 away from the paper outlet 310, so that the third axis line N3 can be set closer to the first end 341, thereby reducing the distance between the paper roll assembly 33 and the first end 341. Specifically, it can reduce the paper path of the label paper 331 moving from the paper roll assembly 33 to the first end 341. For thinner label paper 331, the shorter the paper path, the lower the risk of the label paper 331 tearing.
