Description

Technical Field

[0001] This utility model relates to the field of printer technology, specifically to a ribbon printer mechanism assembly and a ribbon printer. Background Technology

[0002] Currently, the ribbon paper feeding structure of ribbon printers on the market (such as Hanprint ribbon printers) is typically as follows: a metal clamping fastener is located on the printer's upper casing. When the printer lid is opened or closed, the metal clamping fastener cuts into the ribbon roller. The ribbon roller is mounted on a metal shaft, with a tower-shaped spring and an E-type plastic retainer fixed to the top of the shaft. When the metal guide rail cuts down, the ribbon roller is pushed forward under pressure, contacting the ribbon feeder. Driven by a motor and gear set, the printed ribbon is then collected. This method, due to the unidirectional clamping fastener cutting into the ribbon roller, requires a larger space, resulting in a larger ribbon printer size. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide a ribbon printer mechanism assembly and a ribbon printer.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is a ribbon printer mechanism assembly and a ribbon printer:

[0005] A ribbon printer mechanism assembly includes an upper cover, a ribbon holder, and a lower cover arranged sequentially from top to bottom. One end of the upper cover is rotatably connected to one end of the lower cover, and the ribbon holder is snapped onto the upper cover.

[0006] A carbon belt gear bracket is fixedly connected to one side of the upper cover. A recovery shaft is rotatably connected to the carbon belt gear bracket. A motor is installed on the carbon belt gear bracket. The recovery shaft is driven to rotate by the motor. A tensioning shaft is rotatably connected to the carbon belt gear bracket. A tensioning gear is fixedly connected to the tensioning shaft. A limiting rack that cooperates with the tensioning gear is fixedly connected to the carbon belt gear bracket.

[0007] The carbon belt gear bracket is bolted to a gear cover. The gear cover has through holes for the recovery shaft and tensioning shaft to pass through. An L-shaped pressure block and an R-shaped pressure block are rotatably connected to the gear cover. The L-shaped pressure block is rotatably connected to the gear cover, and an L-shaped torsion spring is located at the rotatable connection. The R-shaped pressure block is also rotatably connected to the gear cover, and an R-shaped torsion spring is located at the rotatable connection.

An L-shaped retaining ring is located on the recovery shaft, and an L-shaped tower spring is fitted onto the recovery shaft, positioned between the L-shaped retaining ring and the L-shaped carbon belt pulley. An R-shaped retaining ring is located on the tensioning shaft. An R-shaped tower spring is sleeved on the tensioning shaft, and the R-shaped tower spring is located between the R retaining ring and the R carbon belt pulley; both the L carbon belt pulley and the R carbon belt pulley are provided with a stop block one; an L aluminum tube and an R aluminum tube are rotatably connected to the carbon belt bracket; an L carbon belt dial wheel is fixedly connected to the L aluminum tube; an R carbon belt dial wheel is fixedly connected to the R aluminum tube; both the L carbon belt dial wheel and the R carbon belt dial wheel are provided with a stop block two that cooperates with the stop block one; a lower cover support bone is fixedly connected to the lower cover; the L pressure block and the L carbon belt pulley have mutually cooperating slopes at their close ends; the R pressure block and the R carbon belt pulley also have mutually cooperating slopes at their close ends.

[0031] Example 1, in conjunction with Appendix Figure 1-15 A ribbon printer mechanism assembly and a ribbon printer:

[0032] A ribbon printer mechanism assembly includes an upper cover 1, a ribbon support 2, and a lower cover 3 arranged sequentially from top to bottom. One end of the upper cover 1 is rotatably connected to one end of the lower cover 3, and the ribbon support 2 is snapped onto the upper cover 1.

[0033] A carbon belt gear bracket 4 is fixedly connected to one side of the upper cover 1. A recovery shaft 5 is rotatably connected to the carbon belt gear bracket 4. A motor 6 is installed on the carbon belt gear bracket 4. The recovery shaft 5 is driven to rotate by the motor 6. A tensioning shaft 7 is rotatably connected to the carbon belt gear bracket 4. A tensioning gear 8 is fixedly connected to the tensioning shaft 7. A limiting rack 9 that cooperates with the tensioning gear 8 is fixedly connected to the carbon belt gear bracket 4.

[0034] A carbon belt gear bracket 4 is bolted to a gear cover 10. The gear cover 10 has through holes for the recovery shaft 5 and tensioning shaft 7 to pass through. An L-shaped pressure block 11 and an R-shaped pressure block 12 are rotatably connected to the gear cover 10. The L-shaped pressure block 11 is rotatably connected to the gear cover 10, and an L-shaped torsion spring 13 is provided at the rotatable connection. The R-shaped pressure block 12 is rotatably connected to the gear cover 10, and an R-shaped torsion spring 14 is provided at the rotatable connection. An L-shaped carbon belt roller 15 is fitted onto the recovery shaft 5, and an R-shaped carbon belt roller 16 is fitted onto the tensioning shaft 7. An L-shaped retaining ring 17 is provided on the recovery shaft 5, and an L-shaped tower spring 18 is fitted onto the recovery shaft 5, positioned between the L-shaped retaining ring 17 and the L-shaped carbon belt roller 15. An R-shaped retaining ring 20 is provided on the tensioning shaft 7. An R-shaped tower spring 21 is fitted on shaft 7, and the R-shaped tower spring 21 is located between the R retaining ring 20 and the R carbon belt pulley 16; both the L carbon belt pulley 15 and the R carbon belt pulley 16 are provided with a stop block 22; the L aluminum tube 23 and the R aluminum tube 24 are rotatably connected to the carbon belt bracket 2; the L carbon belt pulley 25 is fixedly connected to the L aluminum tube 23; the R carbon belt pulley 26 is fixedly connected to the R aluminum tube 24; both the L carbon belt pulley 25 and the R carbon belt pulley 26 are provided with a stop block 27 that cooperates with the stop block 22; the lower cover 3 is fixedly connected with a lower cover support rib 28; the L pressure block 11 and the L carbon belt pulley 15 have mutually cooperating slopes at their close ends; the R pressure block 12 and the R carbon belt pulley 16 have mutually cooperating slopes at their close ends.

[0035] Working principle:

[0036] 1. In the normal open state, L pressure block 11 and R pressure block 12 are away from the lower cover support rib 28. L carbon belt roller 15 is disengaged from L carbon belt dial 25 under the elastic force of L tower spring 18. R carbon belt roller 16 is disengaged from R carbon belt dial 26 under the action of R tower spring 21. This allows the carbon belt bracket 2 and its components to be removed and assembled without being affected by L carbon belt roller 15 and R carbon belt roller 16.

[0037] 2. In the normal closed and locked state, L-block 11 and R-block 12 abut against the lower cover support rib 28. Under pressure, L-block 11 rotates and presses against L-belt roller 15, causing L-belt roller 15 to move forward and contact L-belt dial 25. Stop 1 22 on L-belt roller 15 and stop 27 on L-belt dial 25 abut against each other to prevent relative rotation between L-belt roller 15 and L-belt dial 25. Under pressure, R-block 12 rotates and presses against R-belt roller 16, causing R-belt roller 16 to move forward and contact R-belt dial 26. The stop block 22 on the R-ribbon roller 16 and the stop block 27 on the R-ribbon dial 26 abut against each other to prevent the R-ribbon roller 16 and the R-ribbon dial 26 from rotating relative to each other. Under the action of the motor 6, the recycling shaft 5 is driven to rotate. The recycling shaft 5 drives the L-ribbon roller 15 and the L-ribbon dial 25 to rotate. The L-ribbon dial 25 drives the L-aluminum tube 23 to rotate, thereby realizing the recycling of the printed ribbon. Under the action of the tension gear 8 and the limiting rack 9, the tension shaft 7 does not rotate, so the R-aluminum tube 24 does not rotate during the recycling process, thus achieving tension.

[0038] In this specific embodiment, a double gear 29, a double gear 30, and a double gear 31 are rotatably connected to the carbon belt gear bracket 4. A driving gear 32 is fixedly connected to the shaft of the motor 6, and a driven gear 33 is fixedly connected to the recovery shaft 5. The driving gear 32 meshes with one gear of the double gear 29, the other gear of the double gear 29 meshes with one gear of the double gear 30, the other gear of the double gear 30 meshes with one gear of the double gear 31, and the other gear of the double gear 31 meshes with the driven gear 33. The rotation of the motor 6 sequentially drives the double gears 29, 30, and 31 to rotate, and the double gear 31 drives the driven gear 33 to rotate, thereby realizing the rotation of the recovery shaft 5 under the action of the motor 6. By adopting gear transmission, the transmission is stable and reliable, and by using multiple double gears as intermediate gears, the spatial layout is more reasonable, the structure is more compact, and the overall volume is smaller.

[0039] A ribbon printer, wherein the core assembly of the ribbon printer is the aforementioned ribbon printer core assembly;

[0040] The upper housing 34 of the ribbon printer is fixedly connected to the upper cover 1, and the lower housing 19 of the ribbon printer is fixedly connected to the lower cover 3.

[0041] When in use, when the upper housing 34 is opened, the upper cover 1 rotates away from the lower cover 3. At this time, the ribbon printer core assembly is in the normal open state, and the ribbon holder 2 and its components can be removed and assembled without being affected by the L ribbon roller 15 and the R ribbon roller 16. When the upper housing 34 is closed, the upper cover 1 rotates closer to the lower cover 3. At this time, it is in the normal closed and locked state, and the motor 6 can be started to recycle the printed ribbon.
