[0002] Resin-based ribbon is a consumable used in thermal transfer printing technology. Its main component is resin. The ink layer on the resin ribbon is transferred to the printing medium (such as labels, barcodes, signs, etc.) through the heating device of the thermal transfer printer to form the required text or pattern. Resin-based ribbon is usually used in occasions with high requirements for printing quality and durability, such as industrial identification, electronic product labels, etc.

[0003] A Chinese utility model with authorization announcement number CN215664341U discloses a carbon ribbon packaging and fixing device.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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 of the embodiments.

[0020] Refer to Figures 1-3, A resin-based carbon ribbon that is easy to install, including a carbon ribbon body 1. A reel is installed inside the carbon ribbon body 1. Fixed plates 2 are clamped on both sides of the reel. Side plates 4 are fixedly connected to the upper ends of the fixed plates 2. A chute 5 is provided on the outer wall of the side plate 4. A slider 7 is slidably connected in the chute 5. A slide plate 3 is installed on the outer wall of the slider 7. Multiple pressing grooves are provided at the lower end of the slide plate 3. Rotating beads 11 are rotatably connected in multiple pressing grooves. A pressing component for driving the rotating beads 11 to press against the outer wall of the carbon ribbon body 1 is installed in the chute 5; the carbon ribbon body 1 is evenly pressed through the rotating beads 11, avoiding the problem of carbon ribbon loosening caused by improper adjustment of traditional pressing strips.

[0021] The pressing component includes a slide bar 6 fixedly connected to the bottom inside the chute 5. The slider 7 is slidably connected to the outer wall of the slide bar 6. A spring 8 is sleeved on the outer wall of the slide bar 6. One end of the spring 8 is fixedly connected to the bottom inside the chute 5, and the other end of the spring 8 is fixedly connected to the lower end surface of the slider 7; the elastic force of the spring 8 is used to provide a pressing force to ensure that the carbon ribbon body 1 is firmly pressed and avoid the carbon ribbon body 1 from loosening.

[0022] A connecting block 10 is fixedly connected to the side wall of the slide plate 3. An engaging block 9 is provided on the outer wall of the slider 7. The connecting block 10 is clamped inside the engaging block 9. The inner wall of the engaging block 9 and the outer wall of the connecting block 10 are both T-shaped, and the outer wall of the connecting block 10 is in close contact with the inner wall of the engaging block 9; the T-shaped structure provides a larger contact area, increases the connection strength and stability, and ensures that it is not easy to loosen during use.

[0023] The outer walls on both sides of the slider 7 are both flat. The outer walls on both sides of the slider 7 are in close contact with the inner walls of the chute 5. Multiple pressing grooves are arranged at equal intervals, and the radius of the opening of the pressing groove is smaller than the radius of the rotating bead 11.

[0024] In the present utility model, when the device is specifically used: Open the carbon ribbon installation area of the printer, ensure that there is no residue of the old carbon ribbon, take out the new resin-based carbon ribbon from the package, and check its condition to ensure that there is no damage. Insert the reel into the inside of the carbon ribbon body 1 so that the carbon ribbon body 1 is in close contact with the reel. The slider 7 slides in the chute 5, enabling the slide plate 3 to freely adjust its position. The slider 7 drives the rotating beads 11 in multiple pressing grooves at the lower end of the slide plate 3 to contact the carbon ribbon body 1 through the sliding guide of the slide bar 6. The rotating beads 11 achieve uniform pressing of the carbon ribbon body 1 through rotation. The elastic force of the spring 8 acts on the slider 7 to provide a continuous pressing force to ensure that the carbon ribbon body 1 always remains in a tight state and avoid loosening. The connecting block 10 on the side wall of the slide plate 3 and the engaging block 9 on the slider 7 are clamped through the T-shaped structure, increasing the overall connection stability, avoiding loosening caused by vibration or external force during use, and at the same time providing a function of quick disassembly.

[0025] Through the above mechanism, the device realizes the convenient installation, uniform pressing and stable fixation of the carbon ribbon, ensuring that the carbon ribbon does not loosen and the printing effect is stable during the printing process.
