Description

Technical Field

[0001] The present application relates to the technical field of hot melt adhesives, and in particular to a filling device for polyurethane hot melt adhesives. Background Art

[0002] Polyurethane hot melt adhesive is a hot melt adhesive made of polyurethane resin. This glue is solid at room temperature, but it will become fluid when heated to a certain temperature, so that it can be coated, sprayed or injected onto the surface of the material to be bonded. Once cooled and solidified, it will form a strong bond. Polyurethane hot melt adhesive is usually used in bonding occasions that require high strength, heat resistance, cold resistance and good flexibility. It is widely used in industrial manufacturing, construction, automobiles, aerospace and other fields. Polyurethane hot melt adhesive needs to be filled and stored after production, so as to facilitate transportation and use.

[0003] According to the Chinese patent number CN216336548U, a filling device for processing reactive polyurethane hot melt adhesive includes a filling machine body, an operating table is fixedly installed on the upper surface of the filling machine body, a stirring mechanism for processing the hot melt adhesive is arranged on the operating table, the stirring mechanism includes a filling barrel, the filling barrel is fixedly installed on the upper surface of the operating table, a top cover is fixedly installed on the upper surface of the filling barrel, a rotating plate is movably installed on the upper surface of the filling barrel, a motor is fixedly installed on the upper surface of the top cover, and a rotating rod is fixedly installed on the output shaft of the motor. In the above patent scheme, the hot melt adhesive inside the filling barrel is stirred, and the filling head is heated by a heater and a heat conducting pipe to prevent the hot melt adhesive from solidifying. However, a conduit is arranged between the filling barrel and the filling head. After filling, the hot melt adhesive retained in the conduit is prone to solidification and adhesion, resulting in clogging of the filling head and the conduit, affecting the use of the filling device. For this reason, we propose a filling device for polyurethane hot melt adhesive. Utility Model Content
