[0035] 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.
[0036] This application provides a wire marking tube printer to solve the problem that, in related technologies, when printing wire marking tubes using a wire marking tube printer, the ribbon cartridge is prone to shaking due to vibration, resulting in unstable contact between the print head and the ribbon cartridge, which in turn easily leads to blurry printing, printing deviation, and printing failure, resulting in poor printing quality.
[0037] Specifically, such as Figures 1 to 3As shown, the wire marking tube printer includes a main unit 10, a cover 21, and a ribbon cartridge 31. The main unit 10 has an upward-opening compartment 11 for holding the ribbon cartridge 31. The cover 21 is rotatably connected to the main unit 10 and can rotate relative to the main unit 10 to open and close the compartment 11. The ribbon cartridge 31 is located inside the compartment 11 and is used to hold the ribbon. The print head in the wire marking tube printer prints the print layer from the ribbon onto the wire marking tube 60, thereby printing labels on the wire marking tube 60 to classify different uses of the wire marking tube 60. The specific working principle of the ribbon has been disclosed in related technologies and will not be elaborated here.
[0038] The inner side of the lid 21 is provided with a first pressing member 22. When the lid 21 is closed on the main unit 10 to close the compartment 11 (e.g.) Figure 3 The first pressing member 22 presses the ribbon box 31 against the main unit 10. Understandably, when the cover 21 is closed on the host 10, it can provide a limit for the ribbon cartridge 31, preventing it from detaching from the cartridge compartment 11. At the same time, the first pressing member 22 presses the ribbon cartridge 31 against the host 10. The first pressing member 22 can abut against the upper surface of the ribbon cartridge 31, making the ribbon cartridge 31 more stable in the cartridge compartment 11. This helps maintain the stability of the ribbon cartridge 31 when the linear marking printer is in the printing state, preventing the ribbon cartridge 31 from shaking due to vibration. This makes the contact between the print head and the ribbon cartridge 31 more stable, thereby preventing problems such as blurry printing, printing deviation, and printing failure that result in poor printing quality. In addition, after printing, when the cover 21 is rotated away from the host 10 to open the cartridge compartment 11, the first pressing member 22 will move with the cover 21 to separate from the ribbon cartridge 31, at which point the ribbon cartridge 31 can be removed. This makes it convenient to fix and unfix the ribbon cartridge 31.
[0039] It should also be noted that when the cover 21 is closed on the main unit 10 to close the cartridge 11, the weight of the cover 21 itself can be used to keep the cover closed, thereby keeping the first pressing member 22 against the ribbon cartridge 31. Of course, the cover 21 can also be connected and fixed by a snap-on structure, a latch structure, a magnetic structure or other locking and unlocking structures to keep the cover closed.
[0040] Furthermore, when the cover 21 is closed on the main unit 10 to close the cartridge compartment 11, the first pressing member 22 elastically abuts against the ribbon cartridge 31 to elastically limit the ribbon cartridge 31, preventing the first pressing member 22 from applying excessive pressure to the ribbon cartridge 31 and damaging the ribbon cartridge 31. At the same time, it can also press and limit ribbon cartridges 31 of different thicknesses and sizes.
[0041] Furthermore, the first pressing member 22 is an elastic telescopic rod or an elastic element, so that when the first pressing member 22 presses against the ribbon cartridge 31, the first pressing member 22 can elastically extend and retract, providing a pressing limit for the ribbon cartridge 31 while preventing excessive pressing force from damaging the ribbon cartridge 31. The elastic element can be a spring, a spring sheet, an elastic rubber block, or other devices made of elastic material.
[0042] In some embodiments, a reinforcing structure 23 is provided around the first pressing member 22. The reinforcing structure 23 is connected to the first pressing member 22 and the cover 21, which can improve the connection strength at the connection between the first pressing member 22 and the cover 21, making the connection between the first pressing member 22 and the cover 21 more secure, and also making the ribbon box 31 more firmly pressed down by the first pressing member 22. The reinforcing structure 23 can be a reinforcing rib provided around the first pressing member 22.
[0043] like Figures 1 to 4 As shown, in some embodiments, the ribbon cartridge 31 includes a winding shaft 311 for winding the ribbon. The winding shaft 311 is spaced apart from the host 10, and when the cover 21 is closed on the host 10 to close the cartridge compartment 11, the winding shaft 311 and the cover 21 are spaced apart. It should be noted that the winding shaft 311 can rotate relative to the cartridge body of the ribbon cartridge 31 around the axis of the winding shaft to release the ribbon wound on the winding shaft 311. The axis of the winding shaft can be parallel to the groove depth direction of the cartridge compartment 11. Since the winding shaft 311 is spaced apart from the host 10 and the cover 21, there is always a winding gap between the winding shaft 311, the cover 21, and the host 10, which can ensure the rotational flexibility of the winding shaft 311, thereby preventing the winding shaft 311 from being unable to rotate and causing printing jams when the ribbon cartridge 31 is pressed by the first pressing member 22.
[0044] In some embodiments, a clearance groove 12 is provided on the bottom wall surface 111 of the cartridge 11, and the winding shaft 311 is positioned opposite to the clearance groove 12, so that the winding shaft 311 is suspended. It can be understood that the winding shaft 311 is located directly above the clearance groove 12, and the inner wall surface of the clearance groove 12 forms a stepped structure with the bottom wall surface 111 of the cartridge 11. The ribbon cartridge 31 is supported on the bottom wall surface 111 of the cartridge 11, thereby suspending the winding shaft 311. The clearance groove 12 can form a clearance space, so that there is always a winding gap between the winding shaft 311 and the bottom wall surface 111 of the cartridge 11, thereby ensuring the rotational flexibility of the winding shaft 311.
[0045] In some embodiments, the ribbon cartridge 31 includes two winding shafts 311, which are parallel and spaced apart. When the cover 21 is closed on the host 10 to close the cartridge compartment 11, the contact portion between the first pressing member 22 and the ribbon cartridge 31 is located between the two winding shafts 311. The area between the two winding shafts 311 is usually the central area of the ribbon cartridge 31, so that the pressing contact point of the first pressing member 22 on the ribbon cartridge 31 is close to the central area of the ribbon cartridge 31, thereby making the overall force on the ribbon cartridge 31 more uniform, preventing the ribbon cartridge 31 from tilting, and thus making the ribbon cartridge 31 more stable.
[0046] In some embodiments, the bottom surface 312 of the ribbon cartridge 31 (e.g.) Figure 6 Both the bottom wall 111 of the cartridge 31 and the bottom surface 312 of the cartridge 31 are flat, and the bottom surface 312 of the ribbon cartridge 31 is in contact with the bottom wall 111 of the cartridge 11, so that the ribbon cartridge 31 and the bottom wall 111 of the cartridge 11 are in surface contact, making the ribbon cartridge 31 more stable and ensuring the stability of the ribbon cartridge 31 during printing.
[0047] like Figures 4 to 6 As shown in some embodiments of this application, a limiting hook 41 is provided on one of the periphery of the ribbon cartridge 31 and the inner wall of the cartridge compartment 11, and a limiting member 42 is provided on the other of the periphery of the ribbon cartridge 31 and the inner wall of the cartridge compartment 11. The limiting member 42 engages with the limiting hook 41 to fix the ribbon cartridge 31. The cooperation between the limiting hook 41 and the limiting member 42 enhances the connection strength between the ribbon cartridge 31 and the host 10, so that the ribbon cartridge 31 is stably fixed in the cartridge compartment 11, further ensuring the stability of the ribbon cartridge 31 during printing.
[0048] Furthermore, multiple limiting hooks 41 are provided, with at least two of the limiting hooks 41 located on opposite sides of the ribbon cartridge 31, so that the periphery of the ribbon cartridge 31 is fixed, thereby making the ribbon cartridge 31 more stable. The number of limiting hooks 41 can be two, three, four or more. The periphery of the ribbon cartridge 31 can be provided with limiting hooks 41 on only two sides, or on three or four sides of the ribbon cartridge 31.
[0049] In some embodiments, a connector 43 is provided on the bottom of the cartridge 11 and the bottom of the ribbon cartridge 31, and a slot 44 is provided on the other bottom of the cartridge 11 and the bottom of the ribbon cartridge 31. The connector 43 is inserted into the slot 44 to fix the bottom of the ribbon cartridge 31, thereby making the ribbon cartridge 31 more stable and achieving the positioning of the ribbon cartridge 31.
[0050] The two corners of the cartridge 11 can be provided with connectors 43, and the bottom of the ribbon cartridge 31 is provided with slots 44 that correspond one-to-one with the connectors 43. The two connectors 43 can be used to limit and fix the entire bottom of the ribbon cartridge 31, so that the ribbon cartridge 31 is placed more stably and can be placed more accurately in the cartridge 11.
[0051] In some embodiments, the bottom of the ribbon cartridge 31 is provided with an abutment post 32, and the bottom of the cartridge compartment 11 is provided with an installation detection component. The installation detection component is used to cooperate with the abutment post 32 to detect whether the ribbon cartridge 31 is installed in the cartridge compartment 11. The installation detection component can detect the installation position of the ribbon cartridge 31. When the ribbon cartridge 31 is installed in the cartridge compartment 11 and is installed in place, the installation detection component can detect the abutment post 32, thereby detecting that the ribbon cartridge 31 has been accurately installed in the cartridge compartment 11. At this time, the installation detection component can send an in-place signal to the control component in the wire marking printer, and the control component can control the print head to perform printing. If the installation detection component does not detect the abutment post 32, the control component will control the print head to remain in a stopped state to prevent the print head from working without load and causing damage to the print head, and also to prevent the print head from starting to print when the ribbon cartridge 31 is not placed stably in the cartridge compartment 11.
[0052] Specifically, the installation detection component includes an actuating protrusion 13 located at the bottom of the cartridge 11. When the ribbon cartridge 31 is installed in the cartridge 11, the abutment post 32 presses against the actuating protrusion 13, so that the installation detection component detects that the ribbon cartridge 31 has been accurately installed in the cartridge 11.
[0053] The ribbon cartridge 31 has a first groove 313 at its bottom, and an abutment post 32 is located in the first groove 313. The top of the abutment post 32 is flush with the bottom surface 312 of the ribbon cartridge 31, or the top of the abutment post 32 is located in the first groove 313. The cartridge compartment 11 has a second groove 14 at its bottom, and an actuating protrusion 13 is located in the second groove 14. The actuating protrusion 13 is an elastic protrusion. When the ribbon cartridge 31 is not placed in the cartridge compartment 11, the actuating protrusion 13 protrudes from the bottom wall surface 111 of the cartridge compartment 11. It is understandable that by hiding the abutment post 32 through the first groove 313, the top of the abutment post 32 will not protrude from the bottom surface 312 of the ribbon cartridge 31. When the ribbon cartridge 31 is not placed in the cartridge compartment 11, the abutment protrusion 13 protrudes from the bottom wall surface 111 of the cartridge compartment 11 so that the abutment post 32 can contact the abutment protrusion 13. When the ribbon cartridge 31 is placed in the cartridge compartment 11, the abutment post 32 can elastically abut against the abutment protrusion 13 and press the abutment protrusion 13 down into the second groove 14, thereby preventing the ribbon cartridge 31 from tilting due to the abutment post 32 abutting against the abutment protrusion 13.
[0054] like Figure 1As shown, in some embodiments of this application, the wire marking tube printer also includes a middle cover 50, which is located inside the cover 21. The middle cover 50 is rotatably connected to the host 10, and the rotation axis of the middle cover 50 is parallel to the rotation axis of the cover 21. The middle cover 50 is provided with a pressing component for pressing and fixing the wire marking tube 60.
[0055] When the lid 21 rotates towards the host 10 to close the cartridge compartment 11, it drives the middle cover 50 to rotate towards the host 10, causing the pressing component to press and fix the wire tube 60. This pressing allows the wire tube 60 to move along a preset trajectory, preventing it from lifting during printing. Furthermore, when the lid 21 is rotated to close the cartridge compartment 11, it drives the middle cover 50 to rotate, thus securing the wire tube 60. This eliminates the need for additional printing steps to close the middle cover 50, further simplifying the printing process, improving printing efficiency, and enhancing the user experience. It should also be noted that the transmission between the lid 21 and the middle cover 50 can be achieved through gear transmission, linkage, or other transmission structures, allowing the lid 21 to drive the middle cover 50 to rotate. Alternatively, when the lid 21 rotates towards the host 10 and contacts the middle cover 50, the lid 21 can directly push the middle cover 50 towards the host 10.
[0056] In some embodiments, a second pressing member 24 is provided on the inner side of the cover 21. When the cover 21 is closed on the main unit 10 to close the compartment 11 (e.g. Figure 3 The second pressing member 24 presses against the middle cover 50, so as to limit and fix the middle cover 50 by using the closing cover 21, so that the middle cover 50 remains closed during the printing process.
[0057] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
