When logs are used as decorative materials, paint needs to be applied on the surface of the logs to improve the ornamental value of the logs and extend their service life. The painted logs need to be dried in a tunnel dryer.

[0003] In order to adapt to the needs of log boards of different thicknesses entering and exiting the tunnel dryer and to minimize the heat exchange between the heat inside the dryer and the outside world, door panels are usually set at the inlet and outlet of the tunnel dryer. The height of the door panels of some dryers is adjusted by a hand-cranked screw, which is a little inconvenient. Therefore, a door panel lifting device for a log board paint dryer is needed, which can monitor the thickness of the board to be dried by an infrared sensor and adjust the height of the door panel by controlling the driving component through a controller, thereby improving the efficiency and accuracy of the door panel height adjustment.
