Thermal transmission tubular marking

A tube marking apparatus comprising:

• a delivery unit including a plurality of supporting rollers and a plurality of operating rollers configured to deliver a tube;
• a thermal press printing unit mounted above the delivery unit and including a first lift cylinder, a first heating device, and a press printing roller, wherein the first heating device and the press printing roller are actuated by the first lift cylinder to move in a vertical direction;
• a guiding unit including a first rotary disc and a plurality of guiding rods, wherein a first transmission printing sheet is mounted to the first rotary disc and carries a plurality of marks thereon, wherein two adjacent marks are continuous to each other or have a spacing therebetween smaller than 50 cm;
• an operating unit for moving the first transmission printing sheet;
• and
• a control unit electrically connected to the delivery unit, the thermal press printing unit, the guiding unit, and the operating unit,
• wherein the delivery unit and the operating unit respectively move the tube and the first transmission printing sheet, and the thermal press printing unit transmissions the plurality of marks of the first transmission printing sheet onto an outer periphery of the tube.
