Automatic pressure heat transfer printing machine

An automatic pressure heat transfer printing machine comprising:

• a machine body, comprising a metal bracket and a shell cover, the metal bracket comprises:
• an upper bracket and a lower bracket arranged up and down at intervals, and a side bracket connecting the same side end of the upper bracket and the lower bracket;
• the shell cover comprises an upper shell enclosing the upper bracket, a lower shell enclosing the lower bracket, and a side shell enclosing the side bracket;
• a drive mechanism, comprising a drive speed change device arranged on the upper bracket, and a screw nut pair extending downwards, an upper end of the screw nut pair is in transmission connection with an output end of the drive speed change device;
• a heat pressing plate component, arranged under the upper shell, comprising a plastic shell, a connecting member, an electric heating plate component and a plurality of elastic connecting devices, a middle part of the connecting member is fixedly connected with a screw nut of the screw nut pair, and the connecting member is connected with the electric heating plate component by the plurality of elastic connecting devices;
• the plastic shell encloses an upper part of the electric heating plate component, and an upper side of the plastic shell is provided with a lower surrounding wall surrounding outside of the connecting member, and a lower side of the upper shell is provided with an upper surrounding wall that is movably fitted with the lower surrounding wall;
• a supporting seat, supported on the lower bracket, is configured to provide support for a heat transfer object;
• a heat dissipation mechanism, comprising:
• a first heat dissipation channel enclosed by the lower surrounding wall and the upper surrounding wall, the first heat dissipation channel communicates with inside of the heat pressing plate component;
• a second heat dissipation channel formed inside the upper shell and connected to the first heat dissipation channel;
• a fan arranged in the second heat dissipation channel for generating heat dissipation airflow.
