Description

Technical Field

[0001] The utility model relates to the field of printers, and more specifically, to a ribbon winding device for printers. Background Art

[0002] A printer is one of the output devices of a computer, used to print the processing results of the computer on relevant media. The ribbon winding device of the printer is an important part of the printer. Its main function is to wind up the used ribbon for the next use or replacement. The traditional ribbon winding device of the printer usually drives the ribbon roll to wind up manually or electrically;

[0003] For example, patent (CN218343128U) discloses a manual ribbon winding device for printers, which realizes rapid winding with a low-cost structure, effectively reduces the cost of purchasing ribbon cartridges. When the ribbon loop squeezes the elastic piece, the protrusion contacts the fixed shaft to generate frictional damping, preventing the winding roller from rotating too fast, causing the ribbon to loosen, resulting in ribbon deviation or adhesion. The elastic piece provided between the unwinding roller and the ribbon loop compensates for the looseness caused by the inconsistent inner core size of the ribbon loop;

[0004] When using the above technology, it is found that the following technical problems exist in the prior art: the torque during the winding process cannot be adjusted, and the ribbon is prone to problems such as wrinkles and breaks due to excessive or too little tension, affecting the service life of the ribbon and the printing effect. Therefore, we designed a ribbon winding device for printers to provide another technical solution to the above technical problems. Summary of the Utility Model

The transverse rotating shaft 4 penetrates through the inside of the L-shaped support base 1 and is rotatably connected to the L-shaped support base 1 through a bearing. A limiting shaft 3 is provided at one end of the top of the L-shaped support base 1. A rotating mechanism for rotating the limiting shaft 3 is provided at one end of the L-shaped support base 1;

[0032] A rotating mechanism for driving the winding shaft 2 to rotate is provided at one end of the L-shaped support base 1;

[0033] The rotating mechanism includes a hydraulic cylinder 8. The output end of the hydraulic cylinder 8 is rotatably connected to a vertical connecting column 9 through a bearing. One end of the vertical connecting column 9 is rotatably connected to an inclined rotating column 10 through a bearing. The bottom of the inclined rotating column 10 is rotatably connected to an L-shaped rotating column 7 through a pin shaft. One end of the L-shaped rotating column 7 close to the L-shaped support base 1 is rotatably connected to a transverse rotating shaft 11 through a bearing. The transverse rotating shaft 11 is fixedly connected to the L-shaped support base 1. One end of the top of the L-shaped rotating column 7 is rotatably connected to the limiting shaft 3 through a bearing. Through the setting of the transverse rotating shaft 11, the L-shaped rotating column 7 can rotate around the transverse rotating shaft 11 as the center;

[0034] A dovetail slider is fixed at one end of the vertical connecting column 9 close to the L-shaped support base 1. A dovetail chute adapted to the dovetail slider is provided inside the L-shaped support base 1. The vertical connecting column 9 and the L-shaped support base 1 are slidably connected through the cooperation of the dovetail slider and the dovetail chute. Through the cooperation of the dovetail slider and the dovetail chute, the vertical connecting column 9 can vertically slide outside the L-shaped support base 1, thereby guiding the vertical movement track of the vertical connecting column 9;

[0035] Here, the operation of the hydraulic cylinder 8 enables the vertical connecting column 9 to vertically lift and lower outside the L-shaped support base 1. The vertical lifting and lowering of the vertical connecting column 9 enables the L-shaped rotating column 7 to rotate around the transverse rotating shaft 11 as the center through the inclined rotating column 10, thereby enabling the limiting shaft 3 to adjust the tension during winding;

[0036] The rotating mechanism includes a vertical gear 12. One end outside the lateral rotating shaft 4 is sleeved with the vertical gear 12. The outside of the vertical gear 12 is sleeved with a vertical connection assembly 5. One end at the bottom of the vertical connection assembly 5 is rotatably connected to a lateral grip 6. A limiting assembly for restricting the rotation of the vertical connection assembly 5 is provided at the top of the vertical connection assembly 5;

[0037] The vertical connection assembly 5 is composed of a vertical fixing plate 17, a vertical support column 18 and a vertical sliding plate 19. The vertical fixing plate 17 is sleeved outside the vertical gear 12 and is slidably connected to the vertical gear 12. A vertical support column 18 is fixed at the bottom of the vertical fixing plate 17. The vertical support column 18 is located inside the vertical sliding plate 19 and is slidably connected to the vertical sliding plate 19.

A vertical through hole is opened inside the vertical fixing plate 17. The gear locking block 13 is slidably connected to the vertical fixing plate 17 through the vertical through hole. Through the arrangement of the vertical rigid spring 15, the gear locking block 13 can move towards the vertical gear 12, and the gear locking block 13 can restrict the vertical gear 12, thereby preventing the vertical fixing plate 17 from rotating outside the lateral rotating shaft 4;

[0039] A handwheel 20 is provided at the bottom of the vertical sliding plate 19. A vertical threaded rod 21 is fixed at the top of the handwheel 20. The vertical threaded rod 21 penetrates through the inside of the vertical support column 18 and is threadedly connected to the vertical support column 18. Anti-slip threads are provided on the outside of the handwheel 20. By rotating the handwheel 20, the vertical threaded rod 21 can rotate, so that the vertical sliding plate 19 can slide vertically outside the vertical support column 18, thereby adjusting the distance between the lateral grip 6 and the lateral rotating shaft 4;

[0040] Here, by holding the horizontal grip 6 by hand and enabling the horizontal rotating shaft 4 to rotate through the vertical connecting component 5, the winding shaft 2 can be rotated accordingly, and the rotation of the winding shaft 2 enables winding. When it is necessary to disassemble the vertical connecting component 5, pull the circular pull block 16 away from the rectangular fixed block 22. The pulling of the circular pull block 16 enables the gear catch 13 to rise vertically inside the rectangular fixed block 22. When the gear catch 13 moves out of the surface of the vertical gear 12, the vertical fixing plate 17 can be disassembled from the outside of the vertical gear 12, enabling the vertical connecting component 5 to be disassembled;

[0041] Rotate the handwheel 20. The rotation of the handwheel 20 enables the vertical threaded rod 21 to rotate.

[0042] During use: The operation of the hydraulic cylinder 8 enables the vertical connecting column 9 to move vertically up and down outside the L-shaped support base 1. The vertical up and down movement of the vertical connecting column 9 enables the L-shaped rotating column 7 to rotate around the horizontal rotating shaft 11 through the inclined rotating column 10, thereby enabling the limiting shaft 3 to adjust the tension during winding;

[0043] Here, by holding the horizontal grip 6 by hand and enabling the horizontal rotating shaft 4 to rotate through the vertical connecting component 5, the winding shaft 2 can be rotated accordingly, and the rotation of the winding shaft 2 enables winding. When it is necessary to disassemble the vertical connecting component 5, pull the circular pull block 16 away from the rectangular fixed block 22. The pulling of the circular pull block 16 enables the gear catch 13 to rise vertically inside the rectangular fixed block 22. When the gear catch 13 moves out of the surface of the vertical gear 12, the vertical fixing plate 17 can be disassembled from the outside of the vertical gear 12, enabling the vertical connecting component 5 to be disassembled;

[0044] Rotate the handwheel 20. The rotation of the handwheel 20 enables the vertical threaded rod 21 to rotate. The rotation of the vertical threaded rod 21 enables the vertical sliding plate 19 to move vertically up and down outside the vertical support column 18, thereby enabling the adjustment of the distance between the horizontal rotating shaft 4 and the horizontal grip 6 and enabling the adjustment of the torque during winding.

[0045] The above is only the preferred specific implementation manner of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
