[0002] Ribbon is a printing consumable primarily used in dot matrix printers. It's made from a woven nylon base that's soaked in ink and dyed. The ribbon is typically wound on a reel. As the ribbon unwinds, its thickness decreases, and the contact between the ribbon and the guide roller decreases, leading to a decrease in tension. Consequently, the tension gradually decreases throughout the unwinding process, resulting in uneven unwinding.

Each shutdown requires time to repair the device or replace the ribbon, which is very time-consuming in the production process, and will greatly reduce the production efficiency of the entire production line and delay production time. Therefore, a ribbon unwinding device is proposed. Utility Model Content

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1: Figure 1 - Figure 4 As shown, the utility model provides a ribbon unwinding device, comprising a base 1, a protective box 11 is fixedly mounted on the upper end of the base 1, an adjustment mechanism 2 is provided on one side of the protective box 11, an unwinding mechanism 3 is provided at one end of the protective box 11, a fixing mechanism 4 is provided at one end of the unwinding mechanism 3, and the unwinding mechanism 3 includes a support plate 31 and an unwinding rod 34;
[0024] The adjustment mechanism 2 includes a connecting base 21 and two groups of guide wheels 24. A concave frame plate 22 is fixedly installed on one side of the connecting base 21, and a cylinder 23 is movably installed on the internal protrusion of the concave frame plate 22. A rotating rod 25 is rotatably installed on one end of the concave frame plate 22, and one end of the rotating rod 25 is rotatably installed inside the protrusion of the inner wall of the concave frame plate 22. An arc-shaped connecting plate 27 is fixedly installed on the outer wall of the rotating rod 25, and a connecting head 26 is movably installed on the outer wall of the arc-shaped connecting plate 27. Two groups of arc frames 28 are fixedly installed on the outer wall of the rotating rod 25, and the two groups of guide wheels 24 are rotatably installed inside the arc frames 28 respectively. One side of the connecting base 21 is fixed to one side of the protective box 11, and the protruding end of the cylinder 23 is fixed to the lower end of the connecting head 26.
[0025] The following describes in detail the specific configuration and function of this embodiment. By starting the cylinder 23, the extended end of the cylinder 23 drives the arc-shaped connecting plate 27 to move through the connector 26. The arc-shaped connecting plate 27 drives the rotating rod 25 to rotate inside the concave frame plate 22. The concave frame plate 22 drives the two sets of guide wheels 24 to move through the two sets of arc frames 28. The height of the two sets of guide wheels 24 can then be adjusted, thereby enabling the tension of the device to be quickly adjusted so that the unwinding device can adapt to different types of ribbons and facilitate unwinding. This prevents the ribbon from breaking during unwinding and the wear of device components. This prevents malfunction of the unwinding device and saves time in repairing the device or replacing the ribbon, thereby greatly improving the production efficiency of the entire production line.
[0026] By movably mounting the two sets of guide wheels 24 inside the two sets of arc-shaped frames 28, when the ribbon is unwound and the ribbon is pulled from the outside to move, the lower surface of the ribbon will rub against the upper surface of the two sets of guide wheels 24, and drive the two sets of guide wheels 24 to rotate inside the two sets of arc-shaped frames 28, thereby applying tension to the ribbon and allowing it to move stably.
[0027] By movably mounting the bottom end of the cylinder 23 in the inner protrusion of the concave frame plate 22, the cylinder 23 can move inside the concave frame plate 22 when in operation, so that the cylinder 23 can drive the connector 26 to move normally. At the same time, when the connector 26 moves, a part of the arc-shaped connecting plate 27 will move inside the connector 26, making it convenient for the connector 26 to drive the rotating rod 25 to rotate through the arc-shaped connecting plate 27.
[0028] Example 2: Figure 1 and Figure 4 As shown, the unwinding mechanism 3 includes a support plate 31 and an unwinding rod 34. A servo motor 32 is fixedly mounted on the upper end of the support plate 31. A rotating disk 33 is provided at one end of the protective box 11.

The No. 1 circular plate 42 is sleeved on the outer wall of the circular guide cylinder 45. One end of the hexagonal bolt 41 passes through the interior of the circular guide cylinder 45 and is threadedly connected to the threaded hole 43.
[0030] The effect achieved by the entire embodiment is that by starting the servo motor 32, the output end of the servo motor 32 drives the rotating disk 33 to rotate, the rotating disk 33 drives the unwinding rod 34 to rotate, and the unwinding rod 34 can drive the ribbon drum to rotate, thereby making it easy to unwind the ribbon drum;
[0031] By putting the second circular plate 44 on the outer wall of the circular guide cylinder 45, and then inserting the hexagonal bolt 41 through the circular guide cylinder 45 into the interior of the threaded hole 43, and turning the hexagonal bolt 41 until it is completely screwed into the interior of the threaded hole 43, and then cooperating with the blocking of the first circular plate 42, the second circular plate 44 can be fixed to the outer wall of the circular guide cylinder 45, so that the ribbon drum can be fixed to the outer wall of the unwinding rod 34, which is convenient for driving the ribbon drum to rotate later;
[0032] The cooperation between the first circular plate 42 and the second circular plate 44 can limit the position of the ribbon drum, making it easier to fix it later.
[0033] The method of use and working principle of this device are as follows: First, the tension of the device is adjusted according to the type of ribbon. By starting the cylinder 23, the extended end of the cylinder 23 drives the arc-shaped connecting plate 27 to move through the connector 26. The arc-shaped connecting plate 27 drives the rotating rod 25 to rotate inside the concave frame plate 22. The concave frame plate 22 drives the two sets of guide wheels 24 to move through the two sets of arc frames 28. The height of the two sets of guide wheels 24 can be adjusted. Then, by putting the ribbon drum on the outer wall of the unwinding rod 34, and then putting the second circular plate 44 on the outer wall of the circular guide cylinder 45, and then inserting the hexagonal bolt 41 through the circular guide cylinder 45 into the threaded The inside of the hole 43 is fixed, and the hexagonal bolt 41 is turned to rotate it until it is completely screwed into the inside of the threaded hole 43.

Finally, the ribbon on the ribbon drum is connected and fixed with other equipment, and the ribbon is located on the upper surface of the two sets of guide wheels 24. Then, by starting the servo motor 32, the output end of the servo motor 32 drives the rotating disk 33 to rotate, and the rotating disk 33 drives the unwinding rod 34 to rotate, and the unwinding rod 34 can drive the ribbon drum to rotate, which is convenient for unwinding the ribbon drum.
