[0025] A thermal transfer printing device, see Figures 1 to 5The device includes a housing 1, with two take-up rollers 2 rotatably connected to the inner side of the housing 1. The two take-up rollers 2 are fixedly connected to both ends of a heat transfer film 3. One take-up roller 2 is responsible for releasing the heat transfer film 3, and the other is responsible for winding it up. The winding roller 2 is equipped with a drive motor for winding. The heat transfer film 3 passes over the surface of a heat-conducting cylinder 203. Two round rods 201 are fixedly connected to the inner wall of the housing 1, and the heat-conducting cylinder 203 is rotatably connected to the outer side of the round rods 201. An electric heating tube 202 is fixedly connected to the inner side of one of the round rods 201. When the heat transfer film 3 is released from the take-up rollers 2, it passes over the surface of the heat-conducting cylinder 203 on one of the round rods 201. The electric heating tube 202 on the inner side of the round rod 201 heats up when energized, and the heat generated is conducted to the heat-conducting cylinder 203, thus preheating the heat transfer film and facilitating subsequent ink removal. Compared to direct heating and printing, this device makes ink removal easier, reduces ink residue, and improves printing quality and efficiency.

[0026] Specifically, such as Figure 3 As shown, a touch switch 8 is embedded in the inner wall of the slot 101, and two heating fans 9 are fixedly connected to the top of the housing 1. After the insert plate 7 is inserted, the touch switch 8 will be triggered. The touch switch 8 is used to control the opening and closing of the heating fan 9. After the heating fan 9 is started, it will blow hot air downwards to heat the heat transfer film 3. Combined with the preheating method, it is more convenient for the ink to be removed.

[0027] Furthermore, such as Figure 2 As shown, a linear guide rail 4 is fixedly connected to the inner top of the housing 1. A slider 401 is slidably connected to the surface of the linear guide rail 4. An electric push rod 5 is fixedly connected to the bottom of the slider 401. A printing plate 6 is fixedly connected to the telescopic end of the electric push rod 5. An electric heating plate 601 is fixedly connected to the inner side of the printing plate 6. After the paper is fixed, the electric push rod 5 is activated to drive the printing plate 6 to descend, pushing the heat transfer film 3 to contact the paper. At this time, the slider 401 moves along the linear guide rail 4, so that the ink on the heat transfer film 3 is printed onto the paper. The linear guide rail 4 is designed to scrape back and forth multiple times, thereby further improving the printing efficiency and reducing ink residue.

[0028] It is worth noting that, such as Figure 2 and Figure 5 As shown, a slot 101 is provided at the bottom of the housing 1. An insert plate 7 is slidably connected to the inner side of the slot 101. The top edge of the insert plate 7 is rotatably connected to a pressure frame 701 via a hinge. A pin 703 is movably inserted into the outer side wall of the insert plate 7. The pin 703 passes through the side wall of the insert plate 7 and is slidably connected to the pressure frame 701. When placing paper, the pressure frame 701 is opened, and then the paper is placed in. Then the pressure frame 701 is closed and the pin 703 is inserted. At this time, the insert plate 7 is inserted into the slot 101, which can ensure the stability of the paper during the printing process.

[0029] It is worth noting that, such as Figure 2 and Figure 5 As shown, a toggle groove 10 is provided on the side wall of the housing 1 on one side of the slot 101. A limit block 12 is slidably connected to the inner side of the toggle groove 10. A spring 11 is fixedly connected between the limit block 12 and the inner side wall of the toggle groove 10. One end of the toggle groove 10 is connected to the slot 101. A limit groove 702 is provided at the edge of the side wall of the insert plate 7. After the insert plate 7 is broken and inserted, the limit groove 702 will be aligned with the toggle groove 10. At this time, the limit block 12 will be pushed into the limit groove 702 under the push of the spring 11, thereby completing the limiting and fixing of the insert plate 7 and ensuring the stability of the insert plate 7.

[0030] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
