Coating device having a coating die configured to discharge a coating liquid onto a workpiece
A coating device includes a backup roll configured to transport a workpiece; a coating die configured to discharge a coating liquid onto the workpiece; a drive section capable configured to drive the backup roll; and a heat dissipation section configured to dissipate heat generated in the drive section.
1 . A coating device comprising:
a backup roll configured to transport a workpiece;
a coating die configured to discharge a coating liquid onto the workpiece;
a drive section configured to drive the backup roll; and
a heat dissipation section configured to dissipate heat generated in the drive section,
wherein the drive section includes a speed reduction section coupled to the backup roll, and a drive motor that is configured to input drive force to the speed reduction section; and
wherein a portion of the heat dissipation section is interposed between the speed reduction section and the drive motor.
2 . The coating device of claim 1 , further comprising a thermal insulation section disposed between the backup roll and the drive section.
3 . The coating device of claim 2 , further comprising:
a support section configured to support the backup roll,
wherein the thermal insulation section is interposed between the support section and the drive section.
4 . The coating device of claim 1 , wherein:
the heat dissipation section includes an interpose section interposed between the speed reduction section and the drive motor; and
a heat dissipation plate provided as a single body with the interpose section or integrally provided to the interpose section, and disposed with a clearance to the drive motor.
