[0002] Printers can print characters on materials such as labels. Printers contain a ribbon cartridge; the ribbon, as a consumable, transfers the ink carried on it onto the label under the heat and pressure of the print head. In related technologies, the ribbon moves and prints within the printer. Because the ribbon's travel path is relatively long, it is susceptible to scratches or wear during printing, resulting in poor print quality. Utility Model Content

[0016] In some embodiments of this application, a first guide post is provided protruding from the first guide surface, and the first guide post is used to provide support for the carbon ribbon.
[0017] In some embodiments of this application, on a plane perpendicular to the axis of the dispensing reel, the outer contour of the orthographic projection of the first transition surface has a first reference point connected to the first guide surface, and the line connecting the orthographic projection of the headband portion and the first reference point is a second line, which is located between the first guide post and the take-up reel.
[0018] In some embodiments of this application, the first guide post is a cylinder, and the axis of the first guide post is parallel to the axis of the dispensing reel.
[0019] In some embodiments of this application, on a plane perpendicular to the axis of the dispensing reel, the outer contour of the orthographic projection of the first guide post has a second reference point farthest from the first guide surface. The distance between the second reference point and the orthographic projection of the headband portion along a direction parallel to the bottom wall of the mounting groove is d1, where d1 satisfies: 2mm≤d1≤3.5mm.
[0020] In some embodiments of this application, a second guide post is provided protruding from the second guide surface, and the second guide post is used to provide support for the carbon ribbon.

After the printing operation is performed at the mounting slot, it is recycled to the ribbon receiving section. This shortens the ribbon's running path as much as possible, thereby reducing the risk of the ribbon being scratched or worn, reducing ribbon loss during the printing process, extending the ribbon's service life, and improving printing efficiency.

[0050] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, a clear and complete description will be provided below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in 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.
[0051] In related technologies, the ribbon moves and prints in the printer. Because the ribbon's movement path is relatively long, the ribbon may scratch or wear when printing, causing the ink on the ribbon to be worn away, resulting in poor printing quality. In some cases, the ribbon may even break due to its long movement path.
[0052] Regarding the above situation, firstly, please refer to [link / reference needed]. Figures 1-3 This application proposes a printing consumable box 100, including a housing 10 and a roll assembly 20.
[0053] The outer side of the housing 10 is provided with a mounting groove 11 for mounting the print head 61 of the printer 200; the reel assembly 20 is disposed on the housing 10, and the reel assembly 20 includes a dispensing reel 21 and a retracting reel 22. The dispensing reel 21 has a dispensing portion 211 for dispensing the ribbon 40, and the retracting reel 22 has a retracting portion 221 for retracting the ribbon 40. The dispensing portion 211, the mounting groove 11 and the retracting portion 221 are connected in sequence, and the ribbon 40 passes through a portion of the peripheral side of the dispensing portion 211 and the mounting groove 11 in sequence to the retracting portion 221.
[0054] Specifically, both the dispensing reel 21 and the take-up reel 22 are used to wind the ribbon 40. The dispensing reel 21 is wound with unused ribbon 40, and the take-up reel 22 is wound with used ribbon 40. The unused ribbon 40 extends from the dispensing section 211 of the dispensing reel 21 and extends along part of the peripheral sidewall of the mounting groove 11. The print head 61 in the mounting groove 11 heats and prints the ribbon 40 located on the sidewall of the mounting groove 11. Subsequently, the heated and used ribbon 40 moves to the take-up section 221 of the take-up reel 22 and is wound onto the take-up reel 22 from the take-up section 221.
[0055] The mounting slot 11 has a first center line M perpendicular to its bottom wall. The first center line M passes through the center point of the bottom wall of the mounting slot 11. The axis of the delivery reel 21 and the axis of the take-up reel 22 are located on opposite sides of the first center line M. That is, the mounting slot 11 has a first end and a second end positioned opposite each other. The axis of the delivery reel 21 is positioned closer to the first end, and the axis of the take-up reel 22 is positioned closer to the second end. This allows the ribbon 40 to pass directly through the mounting slot 11 after exiting the delivery section 211, perform printing at the mounting slot 11, and then be retrieved to the take-up section 221. This results in a shorter ribbon 40 travel path, reducing the ribbon 40's travel distance and minimizing the risk of ribbon abrasion and wear, thus ensuring stable printing results. The first center line M is the center line of the bottom wall of the mounting slot 11, and it is perpendicular to both the axes of the delivery reel 21 and the take-up reel 22.
[0056] It should be noted that, in this embodiment of the application, by reasonably setting the layout and position of the mounting slot 11 and the roll assembly 20, the ribbon 40 directly passes through the mounting slot 11 after coming out of the ribbon delivery section 211. After the printing operation is performed at the mounting slot 11, it is recycled to the take-up section 221. This shortens the running path of the ribbon 40 as much as possible, thereby reducing the risk of the ribbon 40 being scratched or worn, reducing the loss of the ribbon 40 during the printing process, extending the service life of the ribbon 40, and improving printing efficiency.
[0057] Please see Figure 2 In some embodiments of this application, the carbon ribbon 40 forms a travel path from the feed section 211 to the take-up section 221 via the mounting groove 11. The length of the travel path is d4, which satisfies: 40mm≤d4≤70mm. This controls the length of the carbon ribbon 40 released between the feed reel 21 and the take-up reel 22, thereby reducing the risk of wear on the carbon ribbon 40.
[0058] like Figure 4 As shown, the length of the mounting groove 11 along the direction parallel to the bottom wall of the mounting groove 11 is d5, where d5 satisfies: 15mm ≤ d5 ≤ 25mm. The height of the mounting groove 11 along the extension direction of the first center line M is d6, where d6 satisfies: 6mm ≤ d6 ≤ 15mm. By limiting the size of the mounting groove 11, the assembly of the print head 61 with the mounting groove 11 is facilitated, while ensuring that the ribbon 40 travels at a moderate length on the mounting groove 11, avoiding waste due to excessive ribbon length or incomplete printing due to excessively short ribbon length.
[0059] In some embodiments, such as Figure 3As shown, the mounting groove 11 and the roll assembly 20 are arranged at intervals along the extension direction of the first center line M. That is, the roll assembly 20 is located on one side of the mounting groove 11 along the first center line M. Therefore, the ribbon 40 on the roll assembly 20 needs to move along part of the peripheral side of the mounting groove 11 to ensure that the ribbon 40 is taut during the printing process and to avoid printing deviation caused by slack.
[0060] The mounting groove 11 has a first opening on the side opposite to the roll assembly 20. The printing part on the print head 61 faces the first opening. When the ribbon 40 extends along the peripheral sidewall of the mounting groove 11, the ribbon 40 will cover the first opening. At this time, the printing part on the print head 61 can heat and print the ribbon 40.
[0061] Please see Figure 3 In some embodiments of this application, on a plane perpendicular to the first center line M, the orthographic projection of the delivery reel 21 and / or the take-up reel 22 at least partially coincides with the orthographic projection of the mounting groove 11.
[0062] Specifically, the mounting groove 11 has a first guide surface 111, a second guide surface 112 and a third guide surface 113 connected in sequence. The first guide surface 111 is located near the dispensing reel 21, the second guide surface 112 is located opposite to the bottom wall of the mounting groove 11, and the third guide surface 113 is located near the take-up reel 22. Taking the plane perpendicular to the first center line M as the horizontal plane as an example, the roll assembly 20 and the mounting groove 11 are arranged vertically. The orthographic projection of the dispensing roll 21 on the horizontal plane coincides with the orthographic projection of the mounting groove 11 on the horizontal plane. That is, the side of the dispensing roll 21 near the take-up roll 22 is within the orthographic projection range of the mounting groove 11. As a result, after the ribbon 40 extends from the dispensing roll 21, the ribbon 40 will extend upward at an angle and contact the first guide surface 111 of the mounting groove 11, and then move along the circumferential sidewall of the mounting groove 11. This ensures that the ribbon 40 is always taut during operation, reduces the risk of printing deviation caused by the slack of the ribbon 40, and optimizes the printing quality.
[0063] Similarly, the orthographic projection of the take-up reel 22 on the horizontal plane coincides with the orthographic projection of the mounting groove 11 on the horizontal plane. In other words, the side of the take-up reel 22 near the delivery reel 21 is within the orthographic projection range of the mounting groove 11. As a result, when the ribbon 40 moves from the third guide surface 113 to the take-up reel 22, the ribbon 40 will maintain an inclined angle and enter the take-up portion 221 of the take-up reel 22. This ensures that the ribbon 40 has uniform tension during the winding process, reduces wrinkles or breakage of the ribbon 40 caused by uneven tension, further improves printing stability and ribbon 40 utilization, and optimizes printing quality.
[0064] Furthermore, in some embodiments of this application, such as Figure 2As shown, the headband portion 211 is located on the side of the delivery reel 21 closer to the take-up reel 22. Therefore, after the ribbon 40 exits from the headband portion 211, it extends obliquely towards the first guide surface 111 of the mounting groove 11 and moves along the first guide surface 111 to the printing area, ensuring that the ribbon 40 maintains stable tension during movement. Alternatively, in some embodiments, the take-up portion 221 is located on the side of the take-up reel 22 facing the mounting groove 11. Therefore, after the ribbon 40 exits from the third guide surface 113 of the mounting groove 11, it extends obliquely towards the take-up portion 221, ensuring that the ribbon 40 maintains stable tension during movement.
[0065] Please see Figure 3 In some embodiments of this application, the housing 10 has a receiving cavity 12 for mounting the reel assembly 20; when the printing consumable cartridge 100 is in the initial state, the distance between the outer wall of the dispensing reel 21 and the inner wall of the receiving cavity 12 is less than the distance between the outer wall of the retracting reel 22 and the inner wall of the receiving cavity 12.
[0066] Specifically, the initial state of the printing consumable cassette 100 refers to the state when the consumable cassette is not yet in use. At this time, the ribbon 40 is not yet in use, and most of the ribbon 40 is wound on the dispensing ribbon 40. Therefore, the diameter of the dispensing reel 21 is larger than the diameter of the take-up reel 22. As a result, the distance between the outer wall of the dispensing reel 21 and the inner wall of the receiving cavity 12 is smaller, while the distance between the outer wall of the take-up reel 22 and the inner wall of the receiving cavity 12 is larger. This ensures that the ribbon 40 can be smoothly unwound from the dispensing reel 21 and gradually wound onto the take-up reel 22 during the initial use stage, avoiding the ribbon 40 from getting stuck or damaged due to insufficient space.
[0067] Please continue reading Figure 3 In some embodiments of this application, the mounting groove 11 has a first guide surface 111 and a second guide surface 112 arranged adjacent to each other. The dispensing reel 21 is disposed close to the first guide surface 111, and the second guide surface 112 is disposed opposite to the bottom wall of the mounting groove 11. The first guide surface 111 and the second guide surface 112 are connected by an arc-shaped first transition surface 114, which provides support for the carbon ribbon 40. It is easy to understand that the arc-shaped first transition surface 114 can provide a smooth transition for the carbon ribbon 40, reduce the running resistance of the carbon ribbon 40, and reduce the deviation or breakage of the carbon ribbon 40 during turning.
[0068] Further reading is available upon request. Figure 3In some embodiments of this application, on a plane perpendicular to the axis of the dispensing reel 21, the line connecting the projection of the axis of the dispensing reel 21 to the projection of the axis of the take-up reel 22 is a first connecting line, which is inclined from the projection of the axis of the dispensing reel 21 toward the bottom wall away from the mounting groove 11; the second guide surface 112 is inclined from the connection with the first guide surface 111 toward the bottom wall away from the mounting groove 11.
[0069] Specifically, taking the first center line M extending vertically as an example, the bottom wall of the mounting groove 11 is parallel to the horizontal plane, the first connecting line forms a first angle with the bottom wall of the mounting groove 11, and the first connecting line is inclined downward relative to the bottom wall of the mounting groove 11. The second guide surface 112 forms a second angle with the bottom wall of the mounting groove 11, and the second guide surface 112 is inclined upward relative to the bottom wall of the mounting groove 11. This ensures that the ribbon 40 is always taut during the tape feeding process, thereby effectively preventing the ribbon 40 from loosening or falling off, and improving printing quality and stability.
[0070] Please see Figures 2-3 In some embodiments of this application, a first guide post 31 protrudes from the first guide surface 111, and the first guide post 31 is used to provide support for the carbon ribbon 40. It is easy to understand that when the carbon ribbon 40 first reaches the first guide surface 111, it will contact the protruding first guide post 31 on the first guide surface 111, thereby reducing the contact area between the carbon ribbon 40 and the first guide surface 111, reducing frictional resistance, and reducing wear on the carbon ribbon 40.
[0071] Furthermore, such as Figure 3 As shown, the first guide post 31 is a cylinder, and the axis of the first guide post 31 is parallel to the axis of the dispensing reel 21. It is easy to understand that the arc surface of the first guide post 31 can provide a smooth transition for the ribbon 40, reduce the running resistance of the ribbon 40, and reduce the scraping of the ribbon 40.
[0072] Further, please see Figures 2-3 In some embodiments of this application, on a plane perpendicular to the axis of the dispensing reel 21, the outer contour of the orthographic projection of the first transition surface 114 has a first reference point P1 connected to the first guide surface 111 (e.g., ...). Figure 4 As shown in the figure, the line connecting the orthographic projection of the headband section 211 and the first reference point P1 is the second line, which is located between the first guide post 31 and the rewind spool 22.
[0073] Furthermore, on a plane perpendicular to the axis of the dispensing reel 21, the outer contour of the orthographic projection of the first guide post 31 has a second reference point P2 furthest from the first guide surface 111 (e.g., ...). Figure 4As shown), the distance between the second reference point P2 and the orthographic projection of the headband part 211 along the direction parallel to the bottom wall of the mounting groove 11 is d1, and d1 satisfies: 2mm≤d1≤3.5mm.
[0074] It should be noted that, as Figure 2 As shown, on a plane perpendicular to the axis of the dispensing reel 21, the orthographic projection of the headband portion 211 is located to the right of the second reference point P2. Therefore, after the carbon ribbon 40 extends from the headband portion 211, it will tilt upward and contact the first guide post 31. The carbon ribbon 40 tilts at a certain angle during dispensing, which helps the carbon ribbon 40 to be kept taut during the conveyor belt process and reduces the loosening of the carbon ribbon 40 during operation.
[0075] Specifically, if the dimension of d1 is less than 2mm, the entire dispensing reel 21 will be closer to the left side of the mounting slot 11, meaning the distance between the dispensing reel 21 and the return reel 22 will increase. This will easily increase the space occupied by the reel assembly 20, thus increasing the volume of the consumable box. If the dimension of d1 is greater than 3.5mm, the ribbon 40 will tilt upwards at too large an angle after extending from the dispensing section 211, which may cause the ribbon 40 to contact the first guide post 31 too tightly during operation, increasing frictional resistance, or causing the ribbon 40 to contact part of the bottom wall of the mounting slot 11, increasing the wear of the ribbon 40 and affecting the printing effect. In addition, the optimal range of d1 is 2.5mm to 3mm, which ensures that the ribbon 40 is moderately taut while effectively controlling the space occupied by the reel assembly 20, making the internal structure of the consumable box more compact. The specific value of d1 can be adjusted according to actual application needs to ensure that the ribbon 40 maintains a stable tautness under different operating conditions, thereby improving the printing effect.
[0076] Please see Figures 2-3 In some embodiments of this application, a second guide post 32 protrudes from the second guide surface 112, and the second guide post 32 is used to provide support for the carbon ribbon 40. It is easy to understand that when the carbon ribbon 40 first reaches the second guide surface 112, it will contact the protruding second guide post 32 on the second guide surface 112, thereby reducing the contact area between the carbon ribbon 40 and the second guide surface 112, reducing frictional resistance, and reducing wear on the carbon ribbon 40. The number of second guide posts 32 can be one or more, and is not specifically limited here.
[0077] Furthermore, such as Figure 1 As shown, the second guide post 32 is a cylinder, and its axis is parallel to the axis of the dispensing reel 21. It is easy to understand that the arcuate surface of the second guide post 32 can provide a smooth transition for the ribbon 40, reducing the running resistance of the ribbon 40 and minimizing friction.
[0078] Please see Figure 3In some embodiments of this application, the mounting groove 11 has a third guide surface 113, and the reel 22 is disposed close to the third guide surface 113. The third guide surface 113 is connected to the bottom wall of the mounting groove 11 by an arc-shaped second transition surface 115, which provides support for the ribbon 40. It is easy to understand that the arc-shaped second transition surface 115 can provide a smooth transition for the ribbon 40, reduce the running resistance of the ribbon 40, and reduce the deviation or breakage of the ribbon 40 during turning.
[0079] In some embodiments, such as Figures 2-3 As shown, a third guide post 33 protrudes from the third guide surface 113. The third guide post 33 provides support for the ribbon 40. The number of third guide posts 33 can be one or more, without specific limitation. It is easy to understand that after the ribbon 40 reaches the third guide surface 113, it can contact the protruding third guide post 33, thereby reducing the contact area between the ribbon 40 and the third guide surface 113, reducing frictional resistance, and reducing wear on the ribbon 40. The third guide post 33 is cylindrical, and its axis is parallel to the axis of the delivery reel 21. It is easy to understand that the arc surface of the third guide post 33 provides a smooth transition for the ribbon 40, reducing its running resistance and friction.
[0080] Further, please see Figure 4 In some embodiments of this application, on a plane perpendicular to the axis of the take-up reel 22, the outer contour of the orthographic projection of the second transition surface 115 has a third reference point P3 connected to the bottom wall of the mounting groove 11. The distance between the third reference point P3 and the orthographic projection of the take-up portion 221 in a direction parallel to the bottom wall of the mounting groove 11 is d2, and d2 satisfies: 5mm≤d2≤15mm.
[0081] Specifically, if the dimension of d2 is less than 5mm, the entire recycle reel 22 will be closer to the right side of the mounting slot 11, meaning the distance between the recycle reel 22 and the delivery reel 21 will increase. This will easily increase the space occupied by the reel assembly 20, thus increasing the volume of the consumable box. If the dimension of d2 is greater than 15mm, the ribbon 40 will tilt downwards at too large an angle after extending from the second transition surface 115, which may cause the ribbon 40 to break during operation or cause the ribbon 40 to contact part of the bottom wall of the mounting slot 11, increasing the wear of the ribbon 40 and affecting the printing effect. Therefore, the optimal range of d2 is 5mm to 15mm, which can ensure the stable operation of the ribbon 40 and effectively control the space occupied by the reel assembly 20, making the internal structure of the consumable box more compact.
[0082] In some embodiments of this application, such as Figure 4As shown, the distance between the recycle reel 22 and the bottom wall of the mounting groove 11 along the extension direction of the first center line M is d3, where d3 satisfies: 1.5mm ≤ d3 ≤ 5mm. It is easy to understand that if d3 is less than 1.5mm, the risk of friction between the ribbon 40 and the bottom wall of the mounting groove 11 increases; if d3 is greater than 5mm, the distance between the recycle reel 22 and the mounting groove 11 is too large, increasing the size of the printer 200.
[0083] Secondly, such as Figures 5-6 As shown, this application embodiment also provides a printer 200, including a main body 50, a printing assembly 60, and a printing consumable box 100 as described in any of the above embodiments. The main body 50 has a mounting cavity; the printing consumable box 100 is disposed in the mounting cavity.
[0084] Among them, such as Figure 6 As shown, the printing assembly 60 includes a print head 61 and a printing roller 62. The print head 61 is disposed in the mounting groove 11, which has a first opening. The print head 61 is provided with a heating element for heating, which faces the first opening. A paper feeding channel is formed between the print head 61 and the printing roller 62, and the paper feeding channel communicates with the first opening of the mounting groove 11. When the ribbon 40 passes through the mounting groove 11, it will cover the first opening. The printing roller 62 is movably connected to the main body 50 so that the printing roller 62 can press the ribbon 40 and the label paper through the first opening.
