Efficient dissolving device for rosin

The utility model relates to the technical field of rosin processing, in particular to an efficient dissolving device for rosin, which comprises a heating box, a cavity and a rectangular groove are arranged at the top of the heating box, a rosin storage box is arranged in the cavity, a screw rod is arranged in the rectangular groove, an extension block is in threaded connection with the screw rod, and a crushing box is tightly welded at one end of the extension block. According to the device, when a lead screw rotates, an extension block can do lifting motion along the lead screw, when an output shaft of a third motor rotates, a crushing roller can be driven to rotate, solid rosin can directly fall into a rosin storage box from the bottom of a crushing box after being crushed by the crushing roller, and water in a heating box can be heated after the temperature rises after an electric heating pipe is electrified; rosin in the rosin storage box can be softened by heated water, and meanwhile, a plurality of sti
