Hot melting sleeve forming equipment

The hot melting sleeve forming equipment comprises a coiled material barrel and an inner barrel coaxially arranged in the coiled material barrel, the coiled material barrel is formed by annularly and seamlessly splicing four arc-shaped coiled material plates, and the end faces of the two ends of the left coiled material plate and the right coiled material plate are vertical faces; threaded rods are fixedly arranged in the middles of the front end and the rear end of the coiled material plate in the radial direction of the radius, guide rods are symmetrically and fixedly arranged at the positions, on the left sides and the right sides of the threaded rods, of the front end and the rear end of the coiled material plate, and the guide rods are parallel to the threaded rods. A first via hole corresponding to the threaded rod and a second via hole corresponding to the guide rod are formed in the side wall of the inner cylinder. The inner ends of the threaded rods on the upper portion and the lower portion are in t
