Abstract: An automatic pressure heat transfer printing machine, comprising: a machine body, a drive mechanism, a heat pressing plate component, a supporting seat, and a heat dissipation mechanism; the machine body comprises: a metal bracket and a shell cover, the heat dissipation mechanism comprises: a first heat dissipation channel enclosed by a lower surrounding wall and an upper surrounding wall, the first heat dissipation channel communicates with inside of the heat pressing plate component; a second heat dissipation channel formed inside an upper shell and communicating with the first heat dissipation channel and a heat dissipation outlet; a fan arranged in the second heat dissipation channel for generating heat dissipation airflow. Since the heat pressing plate component adopts plastic shell parts, the heat accumulation effect is avoided. The heat dissipation mechanism is provided to actively dissipate heat inside the plastic shell.

Abstract: A liquid candle dye and a method for producing liquid candle dye related to the field of dye technology are provided, wherein the liquid candle dye by weight comprises: 40˜80 parts of an oil-soluble dye; 30˜80 parts of a solvent; and 10-20 parts of an auxiliary agent. The method for producing liquid candle dye of which a preparation method is as follows is provided: step 1: preparing materials according to any one of claims 1 to 3; step 2: soaking the oil-soluble dye in the solvent to dissolve; step 3: putting a soaked mixture in step 2 into a stirring device for stirring and then filtering; and step 4: adding the auxiliary agent to a filtered mixture in step 3, stirring evenly, and then forming a finished product.
