[0022] Through the cooperation of the electric push rod 14 and the positioning plate 15, when the device is in use, the position of the electric push rod 14 can be adjusted by moving the electric push rod 14 along the direction of the guiding groove 16. Subsequently, the positioning plate 15 is pressed down by the electric push rod 14. After the positioning plate 15 is attached to the surface of the support plate 6, the electric push rod 14 is moved again, so that the positioning plate 15 pushes the side surface of the printing board 10, thereby straightening the printing board 10, avoiding the pattern of the heat transfer printing from being skewed due to the skew of the printing board 10. At the same time, through the compression spring 18, when the positioning plate 15 is pushed out, it can be pushed out by the elastic force of the compression spring 18, thereby slowing down the pressure when the positioning plate 15 touches the surface of the support plate 6, and avoiding the situation of wear when the positioning plate 15 is tightly pressed against the surface of the support plate 6 and moves.

[0023] Printing boards 10 are provided on the surfaces of the support plates 6, the surfaces of the positioning plates 15 are attached to the sides of the printing boards 10, and compression springs 18 are movably installed between the surfaces of the positioning plates 15 and the inside of the electric push rods 14.

[0028] When the adjustable positioning device of this heat transfer printing machine is in use, the position of the electric push rod 14 can be adjusted by moving the electric push rod 14 along the direction of the guide groove 16. Subsequently, the positioning plate 15 is pressed down by the electric push rod 14. After the positioning plate 15 is attached to the surface of the support plate 6, the electric push rod 14 is moved again to make the positioning plate 15 push the side surface of the printing board 10, thereby straightening the printing board 10, avoiding the situation that the pattern of the heat transfer printing is skewed due to the skew of the printing board 10. At the same time, through the compression spring 18, when the positioning plate 15 is pushed out, it can be pushed out by the elastic force of the compression spring 18, thereby slowing down the pressure when the positioning plate 15 touches the surface of the support plate 6 and avoiding the situation of wear when the positioning plate 15 is tightly pressed against the surface of the support plate 6 and moves.

[0029] When positioning the printing board 10, when the printing board 10 is made of a relatively soft material, the second hydraulic cylinder 12 can be used to press down the pressing plate 13, so that the pressing plate 13 positions the center of the printing board 10, avoiding the situation that the printing board 10 bends inward due to flexibility when the positioning plate 15 pushes the printing board 10.
