Fast shifting device for waterproof blanket unreeling machine

The utility model relates to a fast shifting device for a waterproof blanket unreeling machine. The fast shifting device comprises a waterproof blanket bracket and a blanket prying lever bracket. The contact surface between a waterproof blanket and each of the waterproof blanket bracket and the blanket prying lever bracket is an inclined surface with a certain inclination. The waterproof blanket bracket is composed of a bearing rod and a supporting rod; the bearing rod is fixedly connected with the supporting rod. The blanket prying lever bracket is composed of a supporting rod, a bearing rod and a prying rod, wherein the bearing rod and the prying rod are positioned on the supporting rod; the bearing rod is movably connected with the prying rod through a hinge shaft. According to the newly-designed fast shifting device for the waterproof blanket unreeling machine, the waterproof blanket can be fast shifted onto an unreeling roller, so that the connection between a front coil of waterproof blanket and a rear coil of waterproof blanket is completed. The fast shifting device for the waterproof blanket unreeling machine has the advantages that the labor force can be saved, the raw material consumption is reduced, the production efficiency is improved, and equipment installation space can also be reduced. According to the fast shifting device for the waterproof blanket unreeling machine, an original auxiliary unreeling machine is removed, and is replaced by the waterproof blanket bracket and two groups of blanket prying lever brackets, so that the equipment installation space is reduced, one auxiliary unreeling machine is eliminated, and the safety coefficient is increased.
