Step on the foot valve again, the positioning plate drops to clamp one end of the resin plate. If the length of the resin plate does not reach the circumference of the positioning roller, it is necessary to stick tape on the other end of the resin plate. The resin plate with a larger width also needs to be taped on both sides to prevent the resin plate from falling off. Close the machine cover, and the laser component and the laser head are displaced along the direction of the sliding rod under the action of the drive device. The positioning roller rotates along the axis under the action of the drive unit to meet the laser engraving of the entire resin plate.
