Smearing device applied to powerful blister varnish

The utility model relates to the technical field of blister, in particular to a smearing device applied to powerful blister oil, which comprises a smearing device shell, an oil storage bottle, a rotating rod, a screw rod and a first motor, the spiral rod is arranged in the rotating rod, when a worker starts the smearing device, the powerful plastic uptake oil can flow into the oil guide pipe along the drainage pipe, and due to the fact that the spiral rod is provided with the spiral blade, the powerful plastic uptake oil is gradually conveyed into the rotating rod under pushing and conveying of the spiral blade; then the strong plastic uptake oil flows to the outside of the rotating rod through the oil outlet in the rotating rod, at the moment, a worker can stretch the rotating rod into the surface of the mold through the smearing device, and then the strong plastic uptake oil is smeared; through the arrangement, the spiral rod is arranged, so that the powerful plastic uptake oil can be uniformly conveyed to
