DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] A thermal transfer device for lettering film, such as Figure 1 and Figure 2 As shown, it includes a base 1, an imprinting seat 2, a fixed cylinder 3, a rotating frame 4, a hot pressing head 5, a square spring 6, a pressure rod 7 and a cleaning mechanism 8. The upper side of the base 1 is connected to the imprinting seat 2, the upper side of the rear of the base 1 is connected to the fixed cylinder 3, the upper side of the fixed cylinder 3 is rotatably connected to the rotating frame 4, the hot pressing head 5 is slidably connected to the rotating frame 4, and extrusion blocks are provided on both sides of the hot pressing head 5 for easy extrusion and cooperation with the pressure rod 7. A square spring 6 is connected between the hot pressing head 5 and the rotating frame 4, and a pressure rod 7 is rotatably connected to the rotating frame 4. A handle is provided on the pressure rod 7 for easy gripping and rotation. The pressure rod 7 is extruded and cooperated with the hot pressing head 5, and a cleaning mechanism 8 is provided on the hot pressing head 5.

[0021] like Figure 1 and Figure 3 As shown, the cleaning mechanism 8 includes a return rail 81, a sliding frame 82 and a cleaning roller 83. The return rails 81 are connected to the front and rear sides of the hot pressing head 5. The sliding frame 82 is slidably connected between the return rails 81, and the cleaning roller 83 is rotatably connected to the sliding frame 82.

[0022] When using the present invention, first move the base 1 to the thermal transfer area of ​​the lettering film, then rotate the rotating frame 4 on the fixed cylinder 3 to drive the hot pressing head 5 to rotate away from the imprinting seat 2 so that the object to be printed can be placed, and then the object to be printed is placed on the imprinting seat 2, and the lettering film is placed on the object, and then the rotating frame 4 is rotated and adjusted to make the hot pressing head 5 located just above the lettering film, and then the pressure rod 7 is held and rotated downward, and the pressure rod 7 is squeezed and matched with the hot pressing head 5 so that the hot pressing head 5 contacts the lettering film and presses the lettering film tightly onto the object to be printed, and the pattern on the lettering film is transferred to the object to be printed by controlling the hot pressing head 5 to heat. When the pressing head 5 is to be cleaned, the sliding frame 82 is made to slide on the return rail 81, driving the cleaning roller 83 to move. When the cleaning roller 83 moves, it contacts the lower surface of the hot pressing head 5, so that the cleaning roller 83 rolls on the hot pressing head 5, cleaning the dust and debris attached to the hot pressing head 5, thereby cleaning the debris or dust attached to the hot pressing head 5, avoiding defects in the transferred pattern, and improving the quality of the thermal transfer product. When the cleaning is completed, the sliding frame 82 is rotated to the top of the hot pressing head 5 through the return rail 81 to facilitate normal hot pressing of the hot pressing head 5. By rotating the sliding frame 82 out from the upper part of the return rail 81, the cleaning roller 83 can be easily replaced.

[0023] like Figure 1 and Figure 4As shown, it also includes a clamping mechanism 9, which includes a sliding seat 91, a circular spring 92 and an auxiliary pressure plate 93. Two groups of sliding seats 91 on the left and right are slidably connected to the base 1, and each group consists of two front and rear sliding seats 91. Auxiliary pressure plates 93 are slidably connected between the sliding seats 91 in the same group. A pulling handle is provided on the auxiliary pressure plate 93 for easy pulling, and a circular spring 92 is connected between the sliding seat 91 and the auxiliary pressure plate 93.

[0024] The clamping mechanism 9 of the present device can be used to clamp the object during thermal transfer. After the object is placed on the imprinting seat 2, the auxiliary pressure plate 93 is pulled upward, the circular spring 92 is squeezed and contracted, and then the sliding seat 91 slides on the base 1. The position of the sliding seat 91 is adjusted to adapt to the size of the object, and then the auxiliary pressure plate 93 is released. The circular spring 92 rebounds, causing the auxiliary pressure plate 93 to move downward to clamp the object, thereby being able to clamp and fix objects of different sizes, avoiding displacement of the object during the printing process and affecting the printing quality.
