[0019] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] See also Figure 1-4 A roller-type thermal transfer machine includes a base 1. The top surface of the base 1 is equipped with an adjustment structure 2 for adjusting the position of a pressure roller 28. An electric heating box 3 is arranged above the base 1. A connecting pipe 31 connected to the interior of the electric heating box 3 is provided on one side of the outer wall thereof. A thermal transfer roller 4 is installed at the other end of the connecting pipe 31. An ink delivery pipe 41 for transporting heated ink is provided inside the thermal transfer roller 4. The ink delivery pipe 41 is fixedly connected to the inner wall of the thermal transfer roller 4 through a radially distributed connecting rod 42. The two ends of the connecting rod 42 are respectively connected to the ink delivery pipe 41 and the interior of the thermal transfer roller 4. An annular electric heating pipe 43 is also installed in the thermal transfer roller 4. Through the thermal insulation heating of the electric heating box 3 and the direct heating of the electric heating pipe 43, the temperature is quickly transferred to the thermal transfer roller 4, ensuring the quality and efficiency of the transfer.

[0022] In this embodiment, a return pipe 37 is installed at one end of the thermal transfer roller 4 and the electric heating box 3 away from the connecting pipe 31, and a plurality of heating wires 301 are installed at the bottom end of the inner part of the electric heating box 3. The outer wall of the connecting pipe 31 is fixedly connected to an oil pump 32 for conveying ink. A temperature sensor is provided on the outside of the connecting rod 31. The heating wire 301 is electrically connected to the PLC controller through the temperature sensor. The heated ink is conveyed through the oil pump 32 and conveyed to the ink delivery pipe 41, so that the ink delivery pipe 41 is heated evenly and transmitted to the thermal transfer roller 4 through the connecting rod 42, thereby ensuring that it is heated evenly and achieves the best working effect.

[0023] Then, the thermal transfer roller 4 is rotatably connected to the ink supply tube 41, and a protective clamping ring 44 is installed between the outer wall of the ink supply tube 41 and the inner wall of the thermal transfer roller 4. Several protective clamping rings 44 are sleeved and fixed on the outer wall of the ink supply tube 41, and several electric heating tubes 43 are fixed on the outer wall of the protective clamping ring 44 by bolts. The outer walls of the several electric heating tubes 43 are tightly fitted with the inner wall of the thermal transfer roller 4. The protective clamping ring 44 can fix the positions of the several electric heating tubes 43 and prevent heat from being lost to the outside, thereby improving the heating effect.

[0024] It should be noted that the adjustment structure 2 includes a servo motor 21, the output shaft of the servo motor 21 is coaxially keyedly connected to a threaded rod 22, the outer wall of the threaded rod 22 is threadedly connected to a number of moving blocks 23, and a slide groove is provided on the top surface of the base 1. Several moving blocks 23 are slidably connected in the slide groove, and the top surfaces of several moving blocks 23 are fixedly connected to the same support plate 24. By cooperating with the threaded rod 22 and the moving blocks 23, the horizontal lateral position of the pressure roller 28 is adjusted to ensure that the object to be transferred is evenly pressurized.

[0025] It should be noted that a mounting frame 25 is mounted on one side of the top of the support plate 24. A screw rod 26 is vertically connected to the mounting frame 25. A forward and reverse motor 29 is coaxially connected to the top of the screw rod 26. A lifting block 27 is slidably connected to the outer wall of the screw rod 26. The side walls of the lifting block 27 are slidably connected to the inner wall of the frame opening of the mounting frame 25. A pressure roller 28 is fixedly connected to the side wall of the lifting block 27 in the same direction as the moving block 23. The screw rod 26 drives the lifting block 27 up and down, thereby adjusting the height of the pressure roller 28 to accommodate objects of different heights and sizes to be transferred. In this embodiment, the lifting block 27 slides relative to the inner side of the mounting frame 25.

[0026] Furthermore, a fixed plate 33 is installed on the bottom surface of the electric heating box 3, and a symmetrically arranged U-shaped plate 34 is installed on the bottom surface of the fixed plate 33. A fixed roller 35 is fixedly installed on the inner wall of the U-shaped plate 34, and a movable roller 36 is slidably connected to the inner wall of the U-shaped plate 34 below the fixed roller 35. The distance between the fixed roller 35 and the movable roller 36 is adjusted according to the pressure adjustment parameter requirements of the object to be transferred, thereby improving the quality and effect of the transfer.

[0027] Working principle: The user first adjusts the position of the pressure roller 28 through the adjustment structure 2 to ensure that the object to be transferred (thermal transfer film, etc.) is located between the pressure roller 28 and the thermal transfer roller 4 and fits tightly, and adjusts the distance between the movable roller 36 and the fixed roller 35 so that both ends of the object to be transferred are under pressure, so that the several heating wires 301 and the heating tubes 43 work, and the oil pump 32 transports the ink from the electric heating box 3 through the connecting tube 31 to the ink delivery tube 41 inside the thermal transfer roller 4. The thermal transfer roller 4 is heated, and then the object to be transferred can be transferred.

[0028] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the utility model disclosed in this application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the utility model.
