A rotary motor is fixedly installed on the top of the rotary motor, and the output end of the rotary motor is connected with the roller shaft through a conveyor belt, and a temperature detection mechanism is fixedly installed on the hot oil roller. In this temperature-controlled printing equipment for PVC decorative film processing, the buoyancy ring will float on the oil surface. When the oil level in the hot oil roller rises, the buoyancy ring will slide up under the action of its buoyancy. Under the action of the magnetic force between the block and the sliding magnetic plate, the sliding magnetic plate moves up in the linkage cavity. At this time, the gas in the upper cavity enters the sliding groove through the conduit, so that the pressure in the sliding groove increases, thereby making the sliding groove inside the sliding groove. The fitting tool slides to the outside and blocks the side wall of the sliding groove, so that the sealing performance of the temperature detection mechanism is better.
