Description

Technical Field

[0001] This utility model relates to the field of printer technology, specifically to a ribbon drive switching structure for a printer. Background Technology

[0002] A printer is an output device that converts text or image information from a computer or other electronic device into a hard copy that can be directly read or used by humans.

[0003] Currently, most multicolor printers use single-color ribbons. Changing colors requires replacing the ribbon, which is time-consuming, labor-intensive, and reduces printing efficiency. Specifically, replacing the ribbon involves multiple steps: opening the ribbon cartridge, removing the used ribbon, inserting a new ribbon, and reinstalling and adjusting the cartridge. These steps increase user time and workload and can lead to errors during printing, such as incorrect ribbon installation or misalignment, affecting print quality. Furthermore, frequent ribbon changes increase consumable costs and reduce overall printing efficiency, especially for tasks requiring frequent color changes. Therefore, a ribbon drive switching mechanism is needed to address these issues. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0028] A ribbon drive switching structure for a printer includes a main body 1, on the side of which a first ribbon drive assembly 2, a second ribbon drive assembly 3, and a ribbon switching assembly 4 are fixedly connected.

[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the main body 1 includes a mounting plate 101; the first ribbon drive assembly 2 includes a first variable frequency motor 201, the output end of which is fixedly connected to a first disc holder 202; the second ribbon drive assembly 3 includes a second variable frequency motor 301, the output end of which is fixedly connected to a second disc holder 302; the ribbon switching assembly 4 includes a slide 401, with telescopic rods 402 installed at both the top and bottom of the slide 401; a slider 403 is fixedly connected to the output end of the telescopic rods 402; a vacuum generator 404 is installed at the bottom of the slider 403; an air pipe 405 is fixedly connected to the output end of the vacuum generator 404; and the bottom of the air pipe 405 is fixedly connected to... The device includes a vacuum suction cup 406. The adsorption mechanism, consisting of two vacuum generators 404, an air tube 405, and the vacuum suction cup 406, adsorbs the first conveying ribbon body 204 and the second conveying ribbon body 304, respectively, enabling ribbon switching. The combination of the vacuum generators 404 and the vacuum suction cup 406 can complete the adsorption and release of the ribbon in a short time, thus achieving rapid switching. It can also accurately adsorb specific positions of the ribbon, ensuring the stability and accuracy of the ribbon during the switching process. It has high reliability and stability and can maintain a good working condition during long-term operation. Vacuum adsorption can adapt to ribbons of different materials and thicknesses, and has strong versatility.

[0030] The first variable frequency motor 201 and the second variable frequency motor 301 are mounted on the side of the mounting plate 101. Two sliders 403, vacuum generators 404, air pipes 405, and vacuum suction cups 406 are provided. A first ribbon reel 203 is mounted on the side of the first tray 202, and a first ribbon conveyor body 204 is fixedly connected to the side of the first ribbon reel 203. A second ribbon reel 303 is mounted on the side of the second tray 302, and a second ribbon conveyor body 304 is fixedly connected to the side of the second ribbon reel 303. The side of the mounting plate 101 is fixed... A connecting plate 102 is connected, and a cross seat 103 is fixedly connected to the side of the connecting plate 102. The first variable frequency motor 201 and the second variable frequency motor 301 respectively feed the ribbon on the first ribbon reel 203 and the second ribbon reel 303. The variable frequency motor can precisely adjust the speed as needed, thereby controlling the ribbon feeding speed. It can quickly switch from one ribbon to another, greatly shortening the time required for ribbon switching and improving the printer's working efficiency. The advantages are more obvious, especially in printing tasks that require frequent color switching.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a first bearing roller 205 is fixedly connected to the side of the mounting plate 101, and several first bearing rollers 205 are provided. A second bearing roller 305 is fixedly connected to the side of the mounting plate 101, and several second bearing rollers 305 are provided. The first bearing rollers 205 and the second bearing rollers 305 provide support and guidance through contact with the ribbon, ensuring that the medium remains stable during transmission. This can effectively prevent the ribbon or paper from shifting or twisting during transmission, ensuring the accuracy of the printing or processing process. Through reasonable support, friction between the medium and other parts of the equipment is reduced, extending the service life of the medium.

[0032] The working process of this utility model is as follows: When the ribbon transmission switching structure of the printer designed in this scheme is in operation, the vacuum generator 404 is activated, which creates a vacuum at the vacuum suction cup 406 through the air pipe 405 to prepare for ribbon adsorption. The first variable frequency motor 201 and the second variable frequency motor 301 are adjusted to adjust and change the conveying state of the first ribbon reel 203 and the second ribbon reel 303. The telescopic rod 402 pushes the slider 403 to move along the slide groove 401 so that the vacuum suction cup 406 is accurately aligned with the target ribbon for adsorption. The vacuum suction cup 406 firmly adsorbs the first conveying ribbon body 204 or the second conveying ribbon body 304 through the vacuum force generated by the vacuum generator 404. In this process, the combination of the vacuum generator 404 and the vacuum suction cup 406 can accurately adsorb the specific position of the ribbon, ensuring the stability and accuracy of the ribbon during the switching process.
