[0015] In some embodiments, the angle between the paper output direction of the first paper output outlet and the paper input direction of the second paper output inlet is β, where β satisfies: 175°≤β≤185°.

[0016] In some embodiments, the first paper output channel has a first sidewall adjacent to the side where the clamping position is located, pointing from the side of the support plate facing the clamping position to the side of the support plate away from the clamping position. The first sidewall includes a first paper guide surface and a second paper guide surface, which are spaced apart along the first direction.

[0017] Wherein, the distance between the first paper guide surface and the second paper guide surface along the first direction is h5, and h5 satisfies: 1.5mm≤h5≤5mm.

[0018] In some embodiments, both the first paper guide surface and the second paper guide surface are arc-shaped surfaces protruding toward the first paper output channel.

[0019] In some embodiments, the paper output channel is located on the side of the support plate facing the clamping position.

[0020] In some embodiments, the printer has an inner wall and an outer wall spaced apart, the paper output channel passes through the inner wall and the outer wall, a paper guide strip is protruding on the inner wall, the paper guide strip extends in a third direction, and in a second direction, the paper guide strip is located between the clamping position and the paper inlet.

[0021] Wherein, the second direction is perpendicular to the first direction and extends from the side of the support plate facing the clamping position to the side of the support plate away from the clamping position, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0022] In some embodiments, the outer peripheral side of the paper guide strip is a convex arc surface.

The tension of the pressure roller is directly converted into lateral tension on the paper, forcing the paper to remain straight and avoiding drooping and bending due to gravity or inertia, thereby ensuring the smoothness of paper feeding.

[0047] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0048] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0049] In existing technology, after the consumables have finished printing in the printer body, the paper output of the consumables that have completed the printing task needs to be sent out. However, there is a problem with the paper output not being smooth during the process of the consumables being sent out from the paper output.

[0050] To resolve the above technical issues, please refer to [link / reference]. Figures 1 to 3 This application provides a printer. The printer 10 includes a printer body 100, which includes at least one support plate 110 and at least one pressure roller 120. A clamping position 110a for clamping a label paper 300 is formed between the at least one support plate 110 and the at least one pressure roller 120. The printer is provided with a paper output channel 10a. Please refer to [link to relevant documentation]. Figure 1 and Figure 4 The paper output channel 10a has a paper inlet 10b and a paper outlet 10c, and the support plate 110 is located on the side of the paper inlet 10b away from the paper outlet 10c.

[0051] The printer body 100, as the main structure of the printer 10, provides stable support for all other components, ensuring the stability and durability of the printer 10 during operation. Furthermore, the printer body 100 is the core component of the entire label printer, responsible for controlling the printing process, processing print data, and providing support and power to other components. The printer body 100 integrates key electronic components such as circuit boards, power management modules, and data processing units. Upon receiving a print command, it heats the print head 130 to transfer the ink or toner on the ribbon onto paper or other media, completing the printing task.

[0052] After printing is completed, the label paper 300 is output through the paper output channel 10a. In order to ensure the smooth output of the label paper 300, the printer 10 may be equipped with a pressure roller 120 and a support plate 110. The support plate 110 provides a flat support surface, supports the label paper 300, guides the paper's path, and cooperates with the pressure roller 120 to form a clamping force to ensure the smooth paper feed of the label paper 300.

[0053] In the embodiments of this application, please refer to Figure 4 The distance between the clamping position 110a and the paper inlet 10b in the first direction X is h1, which satisfies: 5mm≤h1≤20mm. h1 can be any two values ​​between 5mm, 7mm, 10mm, 12mm, 15mm, 18mm, 20mm or more. When h1 is within the above range, the distance between the clamping position 110a and the paper inlet 10b is appropriate, preventing the distance from being too far. Since the label paper 300 is relatively soft, this avoids the label paper 300 from being suspended for too long and sagging due to gravity or inertia, which would affect the smoothness of the paper feeding. The appropriate distance between the clamping position 110a and the paper inlet 10b can ensure that the suspended section of the label paper 300 before entering the channel is greatly shortened. The tension of the pressure roller 120 is directly converted into lateral tension on the paper, forcing the paper to remain straight and avoiding sagging or bending due to gravity or inertia, thereby ensuring the smoothness of the paper feeding.

[0054] In addition, since there may be a height difference between the clamping position 110a and the paper inlet 10b, when h1 is within the above range, the label paper 300 can also avoid a large bending angle, ensuring the continuity of the label paper 300 and thus ensuring the smoothness of the label paper 300 feeding.

[0055] It is understandable that the first direction X is perpendicular to the first surface 10d, and the paper outlet 10c is located on the first surface 10d, so that... Figure 1 As shown in the orientation reference, the first surface 10d is the right side of the printer 10. When the user holds the printer 10, the palm is on the bottom surface of the printer 10 and the fingers are against the right side of the printer 10. Therefore, when the user holds the printer 10, the first direction X is approximately perpendicular to the direction of gravity, that is, the first direction X is approximately parallel to the horizontal direction. By limiting the size of the clamping position 110a and the paper feed 10b in the first direction X, it is possible to avoid the label paper 300 from feeding in other directions, which would result in a large bending angle of the label paper 300 and thus affect the smoothness of the label paper 300 feeding.

[0056] Since the paper path of the label paper 300 in the printer body 100 is relatively long, the printer body 100 may be equipped with multiple support plates 110 and multiple pressure rollers 120. The multiple support plates 110 and multiple pressure rollers 120 are set one-to-one. The paper path of the label paper 300 is limited by the multiple support plates 110 and multiple pressure rollers 120. Multiple clamping positions 110a can fix the label paper 300 in sections and prevent the paper from sagging or deforming. Especially during high-speed printing, it can avoid paper jams or printing misalignment caused by paper loosening and ensure the smoothness of the label paper 300 feeding.

[0057] Among them, the clamping position 110a formed between the support plate 110 adjacent to the paper inlet 10b and the corresponding pressure roller 120 in the multiple support plates 110 is the clamping position 110a closest to the paper inlet 10b in the first direction X. This clamping position 110a can be positioned as the first clamping position. In order to ensure that the label paper 300 between the first clamping position and the paper inlet 10b is in a straight state, the distance between the first clamping position and the paper inlet 10b in the first direction X is h1, where h1 satisfies: 5mm≤h1≤10mm. In this way, the tension of the pressure roller 120 is directly converted into lateral tension on the label paper 300, forcing the label paper 300 to remain straight and avoiding drooping and bending due to gravity or inertia, thereby ensuring the smoothness of paper feeding.

[0058] It can be understood that there can be multiple support plates 110 or one support plate 110. When there is one support plate 110, there is also one pressure roller 120. In one embodiment, the support plate 110 is formed by at least part of the print head 130. That is, the print head 130 integrates printing and support functions, reducing the number of parts, simplifying the assembly process, and reducing material costs. The pressure roller 120 presses the label paper 300 against the print head 130, so that the ribbon and the label paper 300 are stably attached, and the hot melt ink is evenly penetrated to the surface of the label paper 300, thereby ensuring the printing effect.

[0059] Please see Figures 4 to 7 In one embodiment of this application, the paper output channel 10a includes a first paper output channel 200a, and the printer 10 also includes a consumable box 200. The consumable box 200 is disposed inside the printer body 100. The first paper output channel 200a is formed on the consumable box 200. The first paper output channel 200a has a first paper output inlet 200b and a first paper output outlet 200c. The first paper output inlet 200b forms a paper inlet 10b.

[0060] The consumable box 200 is designed with a dedicated roll support that can hold 300 rolls of label paper or ribbon rolls. The consumable box 200 has an integrated curved guide plate that allows the label paper 300 to smoothly transition from the label paper 300 roll to the first paper output inlet 200b, reducing paper deformation caused by sharp bends.

[0061] In this embodiment, the distance between the clamping position 110a and the first paper output inlet 200b along the first direction X is h2, and h2 satisfies: 5mm≤h2≤10mm. h2 can be any two values ​​between 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or more. When h2 is within the above range, that is, the distance between the clamping position 110a and the first paper output inlet 200b is appropriate, the volume of the consumable box 200 is appropriate, thereby ensuring the miniaturization and lightweight design of the entire printer.

[0062] Following the above, the printer also has a second direction Y, which is perpendicular to the first direction X, and extends from the side of the support plate 110 facing the clamping position 110a to the side of the support plate 110 away from the clamping position 110a. Figure 3 The indicated orientation is referenced, and when the printer 10 is held in hand, the second direction Y is approximately the direction of gravity.

[0063] Please refer to Figure 6 The distance between the clamping position 110a and the first paper output inlet 200b along the second direction Y is h3, and h3 satisfies: 0.5mm≤h3≤5mm. h3 can be any two values ​​between 0.5mm, 1mm, 2mm, 3mm, 4mm, 5mm or above. When h3 is within the above range, the distance between the clamping position 110a and the first paper output inlet 200b is appropriate. This avoids the fact that if the value of h3 is too large, it will increase the paper output angle of the label paper 300. If the paper output angle is too large, it will cause the paper output to be unsmooth. At the same time, it also avoids the value of h3 being too small. When the consumable box 200 is installed on the printer body 100, the ribbon in the consumable box 200 will rub against the label paper 300 and the print head 130, thus ensuring the reliability of the consumables when the consumable box 200 is installed.

[0064] Furthermore, please refer to Figure 5 and Figure 6 In one embodiment of this application, the paper output channel 10a includes a second paper output channel 100a. The printer body 100 forms a second paper output channel 100a. The second paper output channel 100a has a second paper output inlet 100b and a second paper output outlet 100c. The second paper output outlet 100c forms a paper output port 10c. That is, after the label paper 300 is printed, it first passes through the first paper output channel 200a of the consumable box 200, and then exits through the second paper output channel 100a on the printer body 100.

[0065] The distance between the first paper outlet 200c and the second paper inlet 100b along the first direction X is h4, where h4 satisfies: 0.2mm ≤ h4 ≤ 2mm. h4 can be any two values ​​between 0.2mm, 0.5mm, 1mm, 1.5mm, 2mm, or more. When h4 is within the above range, the distance between the first paper outlet 200c and the second paper inlet 100b is appropriate, ensuring the continuity of the label paper 300 as it passes through the first paper outlet channel 200a and the second paper outlet channel 100a, and preventing the label paper 300 from getting stuck in the gap between the first paper outlet channel 200a and the second paper outlet channel 100a during the paper feeding process.

[0066] Furthermore, since the first paper output channel 200a passes through one side wall of the consumable box 200 and the second paper output channel 100a passes through one side wall of the printer body 100, when h4 is within the aforementioned range, interference between the side wall of the consumable box 200 and the printer body 100 can be avoided when the consumable box 200 is installed on the printer body 100, thus ensuring assembly efficiency.

[0067] Following on from the above, please refer to Figure 7 The angle β between the paper output direction of the first paper outlet 200c and the paper input direction of the second paper inlet 100b satisfies: 175°≤β≤185°, that is, β can be any two values ​​between 175°, 180°, 185° or higher. Figure 7 The orientations shown are for reference only. When A is 175°, the height of the first paper outlet 200c is greater than the height of the second paper inlet 100b. When A is 180°, the first paper outlet 200c is level with the second paper inlet 100b. When β is 185°, the height of the first paper outlet 200c is less than the height of the second paper inlet 100b.

[0068] When β is within the above range, that is, when the angle between the paper output direction of the first paper output outlet 200c and the paper input direction of the second paper output inlet 100b is appropriate, the label paper 300 can be made to flow smoothly when it enters the second paper output channel 100a through the first paper output channel 200a.

[0069] In one embodiment, please refer to Figure 5 Along the side of the support plate 110 facing the clamping position 110a, pointing towards the side of the support plate 110 away from the clamping position 110a, the first paper output channel 200a has a first sidewall 200a1 adjacent to the side where the clamping position 110a is located. The first sidewall 200a1 includes a first paper guide surface 200a2 and a second paper guide surface 200a3. The first paper guide surface 200a2 and the second paper guide surface 200a3 are arranged at intervals along the first direction X.

[0070] By setting the first paper guide surface 200a2 and the second paper guide surface 200a3, the contact area between the first paper output channel 200a and the label paper 300 is reduced, which also reduces the friction between the label paper 300 and the first side wall 200a1, thereby making the paper feed of the label paper 300 smoother.

[0071] It is also important to understand that, in the consumable box 200, the label paper 300 is output after passing through the first paper output channel 200a and the second paper output channel 100a. The ink layer of the thermal transfer ribbon is completely transferred to the label paper 300 after being heated by the print head 130. The same section of ribbon cannot be reused, otherwise it will cause the printed content to be blurry or overlapping. After printing, the used ribbon will be wound onto the take-up shaft to ensure that the unused ribbon part is always aligned with the print head 130, ensuring that each print is a fresh ribbon area.

[0072] Therefore, a ribbon recycling channel communicating with the interior of the consumable cartridge 200 is formed between the first guide paper surface 200a2 and the second guide paper surface 200a3 in the ribbon cartridge. This channel is the distance between the first guide paper surface 200a2 and the second guide paper surface 200a3 along the first direction X, which is also the width of the ribbon recycling channel. Please refer to [link / reference]. Figure 5 The distance between the first paper guide surface 200a2 and the second paper guide surface 200a3 along the first direction X is h5, which satisfies: 1.5mm≤h5≤5mm. h5 can be any two values ​​between 1.5mm, 2.5mm, 3mm, 4mm, 5mm or above. When h5 is within the above range, the distance between the first paper outlet 200c and the second paper inlet 100b is appropriate. This avoids the label paper 300 from easily getting stuck in the ribbon recycling channel during the paper feeding process when h5 is too large. It also avoids the ribbon loop channel from being too narrow when h5 is too small, which would reduce the efficiency of the ribbon installation in the ribbon recycling channel and affect the smoothness of the ribbon during subsequent printing.

[0073] Optionally, both the first paper guide surface 200a2 and the second paper guide surface 200a3 are arc-shaped surfaces protruding towards the first paper output channel 200a. The arc-shaped surface design can help reduce the contact area between the label paper 300 and the paper guide surface, thereby reducing friction and further improving the smoothness of the label paper 300 feeding.

[0074] Please see Figure 6 In one embodiment of this application, the paper output channel 10a is located on the side of the support plate 110 facing the clamping position 110a, so as to... Figure 6Using the orientation shown as a reference, the paper output channel 10a is located above the clamping position 110a, and the pressure roller 120 presses against the support plate 110 from top to bottom. Thus, because the paper output channel 10a is located above the clamping position 110a, the entire label paper 300 will move relatively upward, reducing the contact area with the support plate 110, thereby reducing friction and ensuring the smoothness of the label paper 300 feeding.

[0075] The inventors discovered that when dealing with thinner label paper 300, the pressure roller 120, under the elastic action, will further press the label paper 300 towards the support plate 110, causing the angle of movement of the label paper 300 towards the paper inlet 10b of the paper output channel 10a after printing to increase. Based on this, in one embodiment of this application, the printer 10 has an inner wall surface 10e and an outer wall surface 10d spaced apart, the paper output channel 10a passes through the inner wall surface 10e and the outer wall surface 10d, and a paper guide strip 10e1 is protruding on the inner wall surface 10e. The paper guide strip 10e1 extends along the third direction Z and along the second direction Y, and the paper guide strip 10e1 is located between the clamping position 110a and the paper inlet 10b.

[0076] Wherein, the second direction Y is perpendicular to the first direction X, and points from the side of the support plate 110 facing the clamping position 110a to the side of the support plate 110 away from the clamping position 110a, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0077] The extension direction of the guide strip 10e1 is parallel to the width direction of the label paper 300, and the guide strip 10e1 is located between the clamping position 110a and the paper inlet 10b. In this way, the guide strip 10e1 can support the label paper 300 between the clamping position 110a and the paper inlet 10b, preventing the label paper 300 from drooping and bending due to gravity or inertia, thereby ensuring the smoothness of paper feeding.

[0078] In addition, by "raising" the label paper 300 by the guide strip 10e1, the height of the label paper 300 near the paper inlet 10b can be closer to the height of the paper inlet 10b, making it easier for the label paper 300 to enter the paper feeding channel.

[0079] To reduce friction, the outer peripheral side of the guide strip 10e1 is a convex arc surface, which can further improve the smoothness of the label paper 300 feeding. In one embodiment, the guide strip 10e1 can be cylindrical, and its outer peripheral side can be directly formed with a convex arc surface.

[0080] Following on from the above, please continue reading. Figure 6Along the second direction Y, the distance between the paper guide strip 10e1 and the paper inlet 10b of the paper output channel 10a is h6, where h6 satisfies: 0.8mm ≤ h6 ≤ 2mm. h6 can be any two values ​​between 0.8mm, 1mm, 1.5mm, 2mm, or more. When h6 is within the above range, the distance between the paper guide strip 10e1 and the paper inlet 10b of the paper output channel 10a is appropriate in the second direction Y, avoiding an excessively large h6 value. If the distance between the paper inlets 10b of the paper channel 10a is relatively far, the guide strip 10e1 will have difficulty guiding the thinner label paper 300. At the same time, it is also necessary to avoid the h6 value being too small, that is, the distance between the guide strip 10e1 and the paper inlets 10b of the paper outlet channel 10a is relatively close. In this case, both thick and thin label paper 300 will be guided by the guide strip 10e1, which will increase the contact area of ​​the label paper 300, thereby increasing the friction during paper feeding and reducing the smoothness of paper feeding.

[0081] In one embodiment, please refer to Figure 7 The paper output channel 10a has a first sidewall 200a1 and a second sidewall 200a4 arranged at intervals along the second direction Y. The distance between the first sidewall 200a1 and the second sidewall 200a4 along the second direction Y is h7, which satisfies: 0.8mm≤h7≤1.5mm. h7 can be any two values ​​between 0.8mm, 1mm, 1.2mm, 1.5mm or above. When h7 is within the above range, it can prevent the label paper 300 from jamming due to too small a gap, and also avoid the paper from shifting laterally (in the thickness direction of the label paper 300) due to too large a gap.

[0082] Furthermore, when h7 is within the aforementioned reasonable range, it can be ensured that the distance between the first sidewall 200a1 and the second sidewall 200a4 in the second direction Y will not be too large, that is, it will not increase the size of the printer, thereby ensuring the miniaturization and lightweight design of the entire printer 10.

[0083] In order to make it easier for the label paper 300 to enter the paper output channel 10a, the diameter of the paper inlet 10b gradually decreases along the direction from the paper inlet 10b to the paper output outlet 10c, and the diameter of the paper output outlet 10c gradually decreases along the direction from the paper output outlet 10c to the paper inlet 10b. That is, the paper inlet 10b and the paper output outlet 10c are "trumpet-shaped". The walls of the paper inlet 10b and the paper output outlet 10c can be inclined or curved. In order to more easily guide the paper paper 300 to enter and exit, in one embodiment, the walls of the paper inlet 10b and the paper output outlet 10c are curved.

[0084] The gradually narrowing paper feed 10b guides the paper accurately into the channel, reducing skewing; the gradually narrowing paper output 10c helps the paper remain flat during exit, preventing curling. Through this gradually narrowing structure, the paper is gradually guided during feeding and output, reducing sudden changes in resistance and thus lowering the possibility of paper jams.

[0085] Since the paper output channel 10a is the paper output channel 10a for the label paper 300, the roll of label paper 300 located inside the printer body 100 outputs the label paper 300 through the paper output channel 10a after printing. In order to minimize the friction between the label paper 300 and the side wall of the paper output channel 10a, in one embodiment of this application, please refer to... Figure 8 The paper output channel 10a has two third sidewalls 10f spaced apart along the width direction of the label paper 300. The distance between the third sidewall 10f and the label paper 300 along the width direction of the label paper 300 is h8, which satisfies: 0.1mm≤h8≤0.5mm. h8 can be any two values ​​between 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm or above. When h8 is within the above range, the friction between the label paper 300 and the sidewall of the paper output channel 10a during paper feeding can be reduced, thereby further improving the smoothness of the label paper 300 feeding.

[0086] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application shall still fall within the scope of this application.
