[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 4 shown, the present utility model provides a carbon ribbon cassette device that is convenient for replacing the carbon ribbon, including an outer shell 1. Two fixed blocks 2 are fixedly connected to the inner side wall of the outer shell 1. A push rod 3 is slidably connected inside the fixed block 2. A first spring 4 is sleeved outside the push rod 3. A pressing plate 5 is attached to one side of the first spring 4. The pressing plate 5 is fixedly connected to the push rod 3, which is convenient for driving the push rod 3 to move. A carbon ribbon reel 6 and a carbon ribbon return reel 7 are rotatably connected to the outside of the push rod 3. A pushing block 8 is attached to the outside of the carbon ribbon return reel 7. A second spring 9 is fixedly connected to one side of the pushing block 8.

[0024] Specifically, a bush 10 is sleeved outside the carbon ribbon return reel 7. A carbon ribbon body 11 is sleeved outside the bush 10. A pushing plate 12 is attached to one side of the bush 10. A third spring 13 is attached to one side of the pushing plate 12. The other side of the third spring 13 is fixedly connected to the support rod 18 to prevent the third spring 13 from popping out.

[0025] Furthermore, a slide groove 14 is opened inside the fixed block 2. A slide block 15 is slidably connected inside the slide groove 14, and the slide block 15 is fixedly connected to one end of the push rod 3, so that the push rod 3 will not pop out under the action of the first spring 4, playing a limiting role.

[0026] Furthermore, limiting blocks 16 are fixedly connected to the outer sides of the carbon ribbon reel 6 and the carbon ribbon rewinding reel 7, and the limiting blocks 16 slide inside the bushing 10, which can position the bushing 10, enabling the carbon ribbon reel 6 and the carbon ribbon rewinding reel 7 to drive the bushing 10 and the carbon ribbon body 11 to rotate, allowing it to work properly and facilitating installation.

[0027] It is worth noting that grooves 17 are formed on one side of the carbon ribbon reel 6 and the carbon ribbon rewinding reel 7, and the cross-sectional area of the grooves 17 is the same as the cross-sectional area of one end of the ejector rod 3, which can fix the positions of the carbon ribbon reel 6 and the carbon ribbon rewinding reel 7, preventing dislocation during rotation and enabling the printer to be used normally.

[0028] It should be noted that a support rod 18 is sleeved on the outer side of the carbon ribbon reel 6, a connecting block 19 is rotatably connected inside the support rod 18, and one side of the connecting block 19 is fixedly connected to one side of the carbon ribbon reel 6, which can fix the position of the carbon ribbon reel 6 and facilitate its rotation.

[0029] It is worth introducing that a first rotating block 20 is fixedly connected to one side of the support rod 18, and a second rotating block 21 is rotatably connected to the outer side of the first rotating block 20. Under the action of the second spring 9, the carbon ribbon can be rotated towards the outside of the housing 1, facilitating the staff to replace the carbon ribbon and improving work efficiency.

[0030] Working principle and process:

[0031] When the staff needs to replace the carbon ribbon inside the printer, the staff presses the pressing plate 5 with their hand, so that the pressing plate 5 applies pressure to the first spring 4 attached to one side. The pressing plate 5 drives the ejector rod 3 to slide inside the fixed block 2. Under the action of the slider 15, the ejector rod 3 will not pop out under the action of the first spring 4, playing a role in limiting the position. One end of the ejector rod 3 slides out from the groove 17 opened on one side of the carbon ribbon reel 6 and the carbon ribbon return reel 7. The mutual cooperation between the ejector rod 3 and the groove 17 can fix the positions of the carbon ribbon reel 6 and the carbon ribbon return reel 7, preventing misalignment during rotation and enabling the printer to work properly. At this time, the push block 8 attached to the outer side of the carbon ribbon return reel 7 applies a thrust to it under the action of the second spring 9, pushing the carbon ribbon reel 6 and the carbon ribbon return reel 7 out of the carbon ribbon housing 1, realizing the quick ejection of the carbon ribbon installation mechanism from the carbon ribbon cassette, making it more convenient for the staff to replace the carbon ribbon, saving the time for replacing the carbon ribbon, and improving the working efficiency of the printer. When the push block 8 ejects the carbon ribbon installation mechanism from the carbon ribbon cassette, the third spring 13 fixedly connected to one side of the support rod 18 will apply an elastic force to the push plate 12 sleeved on the outer side of the carbon ribbon return reel 7. The connecting block 19 rotatably connected inside the support rod 18 can fix the position of the carbon ribbon reel 6 to facilitate its rotation. The push plate 12 then pushes the bushing 10 sleeved on the outer sides of the carbon ribbon reel 6 and the carbon ribbon return reel 7. The limiting block 16 fixedly connected to the outer sides of the carbon ribbon reel 6 and the carbon ribbon return reel 7 can position the bushing 10, enabling the carbon ribbon reel 6 and the carbon ribbon return reel 7 to drive the bushing 10 and the carbon ribbon body 11 to rotate, enabling them to work properly and also facilitating installation. The bushing 10 drives the carbon ribbon body 11 sleeved on its outer side to slide outwards, realizing the quick ejection of the carbon ribbon body 11 without the need for the staff to take it out manually, increasing the practicality of the device and improving the efficiency of replacing the carbon ribbon. Because the first rotating block 20 is rotatably connected to the second rotating block 21, under the action of the second spring 9, the support rod 18 drives the first rotating block 20 to move towards the outside of the housing 1, facilitating the staff to replace the carbon ribbon.
