[0037] The pressure adjusting mechanism comprises a pressure regulating screw 5 and an adjusting knob 6 arranged on the top of the pressure regulating screw 5, and the pressure regulating screw 5 is arranged in the rotating plate 4 and is threadedly connected with the rotating plate 4; the heat transfer printing mechanism comprises a heating plate 30 arranged on the bottom of the pressure regulating screw 5 and a bottom plate 12 arranged above the base 1, and the heating plate 30 is above the bottom plate 12; the rotating mechanism is used for driving the heating plate 30 to move away from or close to the bottom plate 12, and the heating plate 30 can abut against the bottom plate 12 after being rotated; by rotating the adjusting knob 6, the pressure regulating screw 5 can be rotated, the distance between the heating plate 30 and the bottom plate 12 is adjusted, and thus the heat transfer printing pressure of the heating plate 30 on the bottom plate 12 is adjusted.
[0038] The pressure detecting mechanism comprises a pressure sensor 17 arranged on the bottom of the bottom plate 12; the control mechanism comprises a control box 22 arranged on the top of the mounting frame 2, and the heating plate 30 and the pressure sensor 17 are electrically connected with the control box 22.

[0044] The rotating plate 4 is movably provided with a positioning column 8. One end of the positioning column 8 is connected with the heating plate 30. In this way, the heating plate 30 can be prevented from shaking, thereby improving the overall structural stability of the heat transfer machine.
[0045] The end of the rotating arm 3 away from the mounting frame 2 is fixedly connected with a handle. In some embodiments, the handle includes a handle one 10 and a handle two 11.

The back of the mounting frame 2 is provided with a power switch 27, a power cord 28 and a Type-c interface 29.
[0047] The heating plate 30 is provided with a containing cavity 301, and a plurality of heating pipes 302 are arranged in the containing cavity 301. The heating plate 30 can be heated by arranging the heating pipes 302. The top of the bottom plate 12 is provided with a silica gel pad 13. In this way, the product to be transferred can be protected from damage and heated uniformly. The bottom of the base 1 is provided with a foot pad 20. In this way, the heat transfer flatbed machine can be placed more stably.
[0048] Working principle: when heat transfer is needed, the product to be transferred with the heat transfer paper pasted is placed on the silica gel pad 13. The equipment is started by controlling the power switch 27, and the temperature and time required for transfer are set on the touch screen 30 of the control box 22. The equipment starts heating and enters the working state. Then, the operator adjusts the pressure adjusting screw 5 by adjusting the knob 6 to adjust the heat transfer pressure. Then, the operator lowers the rotating arm 3 by the handle, and drives the rotating plate 4 to move downward by the connecting rod 19 synchronously, so that the electromagnet 9 is adsorbed on the rotating arm 3, thereby fixing the position of the heating plate 30, so that the heating plate 30 just abuts against the bottom plate 12. When the pressure and temperature reach the preset value, the heat is transferred from the heating plate 30 to the heat transfer paper, and the transfer is completed. During the heat transfer process, the pressure sensor 17 detects the pressure in real time and feeds back the pressure value to the control box 22, which is displayed on the touch screen 30 for real-time monitoring, so as to ensure the accurate control of the pressure during the heat transfer process. After the transfer is completed, the electromagnet 9 loses magnetism and releases the rotating arm 3. The lever structure is lifted by the pneumatic support rod 21, which drives the heating plate 30 to lift up, and the whole heat transfer process is completed.
