Description

Box sealing paste feeding device and system Technical Field The invention belongs to the technical field of box sealing paste feeding, and particularly relates to a box sealing paste feeding device and a box sealing paste feeding system. Background The box sealing paste is a key material for sand mould (core) box closing sealing in casting production, and the coating quality directly influences the molding precision and the surface quality of castings. Before the sand mould is combined, a box sealing paste adhesive tape with certain width and height is required to be coated on the parting surface or core head of the sand mould so as to form a seal and prevent molten metal from leaking during pouring. With the improvement of the automation level of the casting industry, the coating operation of the sealing paste is gradually changed from manual operation to robot automation coating. In an automated coating system, stable, metered supply of the sealer is a precondition for achieving high quality coating.
