Abstract
Description
Technical Field
[0001] This utility model relates to the field of printer technology, and in particular to a ribbon reel mounting structure, a consumable plate, and a ribbon cartridge. Background Technology
[0002] With the growing demand for mobile office and instant printing, traditional photo printing, relying on large equipment or professional stores, struggles to meet the immediate output needs of outdoor activities, instant sharing, and on-site services. Against this backdrop, portable printers, due to their lightweight and portability, are widely used in business, logistics, medical, and outdoor operations. Currently, in the portable photo printing field, dye-sublimation transfer technology uses heat to directly convert solid dye on a ribbon into a gaseous state, which then penetrates to the paper surface and re-solidifies, forming a continuous-tone image. This technology offers advantages such as high print clarity and durability, making it one of the mainstream technologies for portable printers.
[0003] In related technologies, portable printers using thermal sublimation transfer technology generally employ a "pre-installed design" for their ribbon mounting structure. This means the ribbon reel is pre-fixed to a detachable consumable board. During subsequent use, the user must install the entire consumable board into the printer housing and then secure it by closing the top cover. However, existing portable printers often produce paper that is contaminated or has missing sections, resulting in suboptimal print quality. Utility Model Content
[0004] This utility model discloses a ribbon reel mounting structure, a consumable plate, and a ribbon box to solve the aforementioned technical problems existing in related technologies.
[0005] To solve the above problems, the present invention adopts the following technical solution: In a first aspect, this application provides a ribbon reel mounting structure, which includes a cover and a ribbon reel; wherein: The cover has a receiving cavity and an opening communicating with the receiving cavity. The ribbon spool can be received in the receiving cavity through the opening, and the ribbon spool is rotatably engaged with the cover.
[0006] Secondly, this application also provides a consumable board, the disclosed consumable board including a board shell and the aforementioned ribbon roll mounting structure, the board shell having a mounting position, and the cover being disposed at the mounting position.
[0007] Thirdly, this application also provides a ribbon cartridge, the disclosed ribbon cartridge including the aforementioned consumable plate.
[0008] The technical solution adopted in this utility model can achieve the following beneficial effects: The ribbon reel mounting structure, consumable plate, and ribbon box of this utility model, since the ribbon reel is pre-installed in the receiving cavity and forms a rotational fit with the cover, the cover can protect the ribbon reel placed inside. When the cover and consumable plate are installed, based on the protective function of the cover, the operator's fingers can only touch the outer wall surface of the cover, thereby effectively avoiding accidental contact between the operator's fingers and the ribbon on the ribbon reel, which would cause sweat, grease, etc. to adhere to the ribbon or cause the ribbon to fade, thus avoiding ribbon contamination or damage and ensuring printing effect; Meanwhile, as the mounting base for the ribbon reel, even if the cover shifts relative to the consumable board due to uneven operating force, the cover and ribbon reel can remain in a relatively fixed position in real time. This fundamentally avoids the risk of the cover scratching the ribbon. During assembly, the outer edge of the cover is the first part to come into contact with the consumable board, which can also effectively prevent the consumable board from scratching the ribbon reel. This avoids partial printing defects or even the need to replace the entire ribbon, ensuring the printer's print quality. Attached Figure Description

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0012] In related technologies, portable printers typically use a pre-installed ribbon reel design, meaning the ribbon reel is pre-fixed to a detachable consumable board. The entire consumable board must be installed into the printer compartment before printing can begin. However, this can result in the printed paper being contaminated or having partial printing defects.
[0013] During their research, the inventors discovered that during the assembly of the consumable board, after the operator pre-fixes the ribbon reel to the board, they need to fasten a cover at the ribbon reel's mounting point to provide some protection. However, during both the pre-fixing and cover-fastening processes, the operator's fingers easily come into contact with the ribbon surface, causing sweat, oil, and other contaminants to adhere to the ribbon, leading to a decline in print quality, such as blurred text and streaks. Furthermore, due to the small size of the assembly structure between the cover and the consumable board, the cover is prone to shifting during fastening due to uneven force applied by the operator. This can cause the edge of the cover to accidentally contact the ribbon, resulting in wrinkles, scratches, or breakage. Wrinkles or scratches can cause partial print defects, while ribbon breakage requires the operator to reinstall a new ribbon reel, leading to low assembly efficiency.
[0014] In view of this, embodiments of this application provide a ribbon reel mounting structure, a consumable plate, and a ribbon box, which are described below in conjunction with the accompanying drawings. Figures 1-8 The ribbon reel mounting structure, consumable plate, and ribbon box provided in this application will be described in detail through specific embodiments and application scenarios.
[0015] Please see Figure 1 and Figure 2This application discloses a ribbon reel mounting structure, which is applied to a printer. The ribbon reel mounting structure includes a cover 100 and a ribbon reel 200. The cover 100 is the basic component of the ribbon reel mounting structure, providing a mounting base and protection for the ribbon reel 200. Specifically, the cover 100 has a receiving cavity and an opening communicating with the receiving cavity. The ribbon reel 200 can be received in the receiving cavity through the opening, and the ribbon reel 200 is rotatably engaged with the cover 100. For example, the cover 100 can be a cylindrical structure with a circumferential opening, and the extending direction of the cover 100 is coaxial or parallel to the axial direction of the ribbon reel 200. The cover 100 forms mounting sidewalls at both ends in its axial direction, and the two ends of the ribbon reel 200 rotatably abut against the mounting sidewalls of the cover 100.
[0016] In this embodiment, since the ribbon spool 200 is pre-installed in the receiving cavity and rotates with the cover 100, the cover 100 can protect the ribbon spool 200 placed inside. When the cover 100 is installed with the consumable board, based on the protective function of the cover 100, the operator's fingers can only touch the outer wall surface of the cover 100, thereby effectively preventing the operator's fingers from accidentally contacting the ribbon on the ribbon spool 200, which would cause sweat, grease, etc. to adhere to the ribbon or cause the ribbon to fade, thus avoiding ribbon contamination or damage and ensuring the printing effect of the printer.
[0017] Meanwhile, as the mounting base for the ribbon reel, even if the cover 100 shifts relative to the consumable board due to uneven operating force, the cover 100 and the ribbon reel 200 can maintain a relatively fixed position in real time. This fundamentally avoids the risk of the cover 100 scratching the ribbon. At the same time, since the ribbon reel 200 is located inside the receiving cavity, when assembling the integrated structure formed by the cover 100 and the ribbon reel 200 with the consumable board, the outer edge of the cover 100 should be the first part to come into contact with the consumable board during the assembly process. This avoids direct contact between the consumable board and the ribbon reel 200, effectively preventing the consumable board from scratching the ribbon reel 200. This avoids partial printing defects or even the need to replace the entire ribbon, ensuring the printer's print quality.
[0018] In the embodiments of this application, please continue to refer to Figure 1 and Figure 2The ribbon reel mounting structure may also include an elastic element 300, which is disposed between the cover 100 and the ribbon reel 200. The elastic element 300 is configured to apply an elastic force to the ribbon reel 200, so that the ribbon reel 200 and the cover 100 abut against each other axially, thereby achieving a stable installation of the ribbon reel 200 within the cover 100. For example, the elastic element 300 can be a helical spring, which can be provided at one end of the ribbon reel 200 in its axial direction to apply an axial elastic force to the ribbon reel 200. Specifically, the first end of the ribbon reel 200 has a radially outwardly protruding first positioning part 210, which extends circumferentially along the ribbon reel 200. One end of the elastic element 300 abuts against one mounting sidewall of the cover 100, and the other end of the elastic element 300 abuts against the first positioning part 210, so that the second end of the ribbon reel 200 can abut against another mounting sidewall of the cover 100. It is understood that the first end and the second end are opposite ends of the ribbon reel 200.
[0019] Based on the above technical solution, on the one hand, by introducing an elastic element 300 at the end of the ribbon reel 200, the axial length of the ribbon reel 200 can be less than the distance between the two mounting side walls of the cover 100. During installation, the elastic element 300 can be first fitted onto the ribbon reel 200, and the ribbon reel 200 can be easily inserted into the receiving cavity by compressing the elastic element 300, thus improving the ease of installation. After installation, the elastic element 300 can provide a continuous axial preload, so that the ribbon reel 200 can remain in abutting position against the mounting side wall of the cover 100 to avoid shaking, thereby improving the stability of the ribbon reel 200 installed on the cover 100. It should be noted that the elastic element 300 applies an axial elastic force to the ribbon reel 200 only to ensure the axially stable assembly of the ribbon reel 200 and the cover 100. Since the elastic element 300 is sleeved on the outer periphery of the ribbon reel 200, when the ribbon reel 200 needs to rotate to perform winding or unwinding actions, the frictional resistance between the ribbon reel 200 and the mounting side wall and the frictional resistance between the ribbon reel 200 and the elastic element 300 are both small and will not affect the normal winding or unwinding actions of the ribbon reel 200.
[0020] For some embodiments of this application, please refer to Figure 1The second end of the ribbon spool 200 has a radially outwardly protruding second positioning part 220. For example, the second positioning part 220 can be extended circumferentially along the ribbon spool 200. The ribbon spool 200 defines the ribbon winding area between the first positioning part 210 and the second positioning part 220. Through the arrangement of the first positioning part 210 and the second positioning part 220, they can constrain the ribbon wound on the ribbon spool 200 and prevent the ribbon from axially shifting on the ribbon spool. The first positioning part 210 and the second positioning part 220 define the winding position of the ribbon, which is convenient for subsequent accurate color matching printing.
[0021] For further technical solutions, please refer to Figure 1 and Figure 2 The ribbon spool 200 extends beyond the first positioning portion 210 at its first end. This allows the elastic element 300 to be fitted onto the portion extending beyond the first positioning portion 210, increasing the stability of the elastic element's installation. The second positioning portion 220 is located at the second end of the ribbon spool 200. A first positioning recess 110 is provided on the mounting sidewall of the cover 100. The second positioning portion 220 matches the contour shape and size of the first positioning recess 110, and the second positioning portion 220 and the first positioning recess 110 are positioned together to limit the radial displacement of the ribbon spool 200. The radially protruding second positioning portion 220 increases the contact area between the ribbon spool 200 and the mounting sidewall, ensuring assembly stability and preventing the second end of the ribbon spool 200 from disengaging from its positioning position. It is understood that the outer contour of the second positioning portion 220 is circular to allow smooth rotation within the first positioning recess 110, ensuring that the ribbon spool 200 can rotate for winding or unwinding.
[0022] For some embodiments of this application, please refer to Figure 1 The cover 100 is also provided with a third positioning part 120 in the receiving cavity. The third positioning part 120 is a non-closed structure that extends circumferentially along the inner wall of the cover 100. The third positioning part 120 is integrally formed with the cover 100. The width of the notch formed at the non-closed end of the third positioning part 120 is smaller than the diameter of the ribbon spool 200. The ribbon spool 200 can be inserted into the third positioning part 120 through the notch, thereby further improving the stability of the ribbon spool 200 installed on the cover 100 and preventing the ribbon spool 200 from lifting off.
[0023] For further technical solutions, please refer to Figure 2Under the elastic force of the elastic member 300, the third positioning part 120 is also configured to axially abut against the first positioning part 210. The frictional force between the first positioning part 210 and the third positioning part 120 can resist the radial sway of the elastic member 300, thereby keeping the first end of the ribbon spool 200 stably in the receiving cavity and preventing the first end of the ribbon spool 200 from lifting and detaching due to the radial sway of the elastic member 300, thus strengthening the stability of the connection between the ribbon spool 200 and the cover 100. It should be noted that the ribbon spool 200 defines the winding area of the ribbon in the first positioning part 210 and the second positioning part 220, and the axial extension width of the ribbon can be less than the distance between the first positioning part 210 and the second positioning part 220. For example, when the third positioning part 120 is formed in the receiving cavity of the cover 100, the ribbon can be located between the third positioning part 120 and the second positioning part 220.
[0024] In a further technical solution, the ribbon spool 200 is a hollow structure with at least one end through it. A fourth positioning part 130 is also provided on the mounting side wall of the cover 100. For example, the ribbon spool 200 is a hollow structure with both ends through it. The fourth positioning part 130 can be a conical column structure or a cross pin structure. The fourth positioning part 130 can be inserted into the hollow structure of the ribbon spool 200 to position one end of the ribbon spool 200. And through the limiting cooperation between the third positioning part 120 and the other end of the ribbon spool 200, the ribbon spool 200 is stably installed in the cover 100, thereby ensuring the stability of the winding and unwinding actions of the ribbon spool 200, and thus ensuring the printing quality and effect. Further details are omitted here.
[0025] Please see Figures 3-6 This application also discloses a consumable board, which includes a board shell 400 and the aforementioned ribbon roll mounting structure. The board shell 400 has a mounting position 410. For example, the mounting position 410 can be two wall structures that are disposed opposite to each other on both sides of the length direction of the board shell 400, and the cover 100 is disposed at the mounting position 410.
[0026] In the embodiments of this application, please refer to Figure 1 , Figure 3 and Figure 4A concave-convex fitting structure is provided between the cover 100 and the mounting position 410. For example, one of the cover 100 and the mounting position 410 is provided with an insertion protrusion 140 and the other is provided with an insertion recess 411. The cover 100 is connected to the shell 400 through the insertion of the insertion protrusion 140 and the insertion recess 411. For example, both ends of the cover 100 are provided with insertion protrusions 140 and the insertion recess 411 is provided at the mounting position 410. During the installation process, the cover 100 can abut against the mounting position 410 and force it to deform slightly, so that the insertion protrusion 140 is inserted into the insertion recess 411. It can be understood that, since the mounting position 410 is a wall structure, it can deform slightly when the cover 100 is snapped in, and the mounting position 410 can restore its deformation after the cover 100 is installed in place.
[0027] In the embodiments of this application, please refer to Figure 4 , Figure 5 and Figure 6 The housing 400 is provided with a paper output port 420 and a paper feed window 440. When the housing 400 is installed on the printer, the paper output port 420 and the paper feed window 440 are respectively aligned with the paper tray. The printer's paper feed roller can enter the paper tray through the paper feed window 440 to feed the paper out from the paper output port 420.
[0028] In the embodiments of this application, please refer to Figure 6 and Figure 7 The shell 400 has an inclined portion 450, which is inclined relative to the horizontal plane. The paper outlet 420 is opened on the inclined portion 450, so that the paper outlet 420 is inclined relative to the horizontal plane. During the paper retraction process, the inclined portion 450 can guide the retracting paper and avoid the paper from being greatly obstructed during the retraction process and causing bending and wrinkles. In a preferred embodiment, the inclination angle of the inclined portion 450 can be less than 30°, further weakening the obstruction effect on the paper retraction and ensuring the smoothness of the paper retraction.
[0029] In a further technical solution, the width of the paper outlet 420 gradually decreases in the direction extending from its middle to both ends. For example, when viewed from a perspective perpendicular to the inclined portion 450, the paper outlet 420 can be an isosceles triangle or an arc shape. On the one hand, the shape of the paper outlet 420 being wider in the middle and narrower on both sides can enhance the strength of the integral connection between the inclined portion 450 and the shell 400. On the other hand, based on the design of the paper outlet 420 being wider in the middle and narrower on both sides, when the paper feed roller feeds the paper outward, even if the paper undergoes a certain degree of bending deformation, the paper can still be fed out normally from the paper outlet 420, which increases the paper feeding tolerance and avoids paper jams.
[0030] Meanwhile, since the paper needs to move forward and backward multiple times during the printing process, based on the design of the paper output port 420, which is wider in the middle and narrower on both sides, the rear two sides of the paper are more likely to come into contact with the inclined part 450 during the paper retraction process, and are then guided back by the inclined part 450. This method makes it difficult for the paper to be precisely aligned with the paper output port 420 during the retraction process, effectively avoiding the situation where the paper retracts into the paper tray, thereby ensuring the stability and reliability of the printer printing.
[0031] In this embodiment of the application, a positioning protrusion 430 is provided on the plate housing 400. For example, the positioning protrusion 430 can be a positioning post located on the outside of the mounting position 410. The plate housing 400 can be positioned and assembled with the printer housing through the positioning protrusion 430, thereby ensuring the stability of the consumable board installation. It should be noted that there can be multiple positioning protrusions 430, and multiple positioning protrusions 430 can be distributed in different parts of the plate housing 400. This application does not make specific limitations in this regard.
[0032] For further technical solutions, please refer to Figure 8 The plate housing 400 is also provided with a buckle 460. When the consumable plate is assembled into the printer housing, it can be connected and fixed by the buckle 460 to the printer housing.
[0033] For some embodiments of this application, please refer to Figure 9 The housing 400 may also be provided with a tag chip 500. For example, the tag chip 500 may be an RFID chip. The printer may be equipped with an identification device. After the consumable board is installed in the printer, the identification device in the printer can identify the tag chip 500. Only after the identification device successfully identifies the specific information stored or transmitted by the tag chip 500 can the subsequent printing action be performed. This avoids the user from accidentally installing consumable boards of different models, specifications or incompatible types into the printer. The presence of the tag chip 500 enables the printer to accurately identify the compatibility of the consumable board.
[0034] This application also provides a ribbon cartridge, which includes the aforementioned consumable board.
