[0001] The utility model relates to the technical field of glue guns, in particular to a glue gun for a highly flame-retardant polyurethane foam sealant. Background Art

[0002] At present, the domestic polyurethane foam sealant is mainly single-component. Single-component polyurethane foam sealant is a moisture-curing, multi-purpose polyurethane foam filling elastic sealing material. During construction, the aerosol colloid is sprayed to the construction site through a matching glue gun or manual nozzle, and the molding, foaming, bonding and sealing processes are completed in a short time. The cured foam elastomer has excellent properties such as bonding, waterproofing, resistance to thermal expansion and contraction, heat insulation, sound insulation and even flame retardancy, so it is widely used.

[0003] After consulting the literature, it is learned that the currently published patent: CN216936870U discloses a glue gun for the construction of polyurethane foam filler, including a gun body, on which a glue injection cavity and a drying agent cavity that are not connected to each other are arranged side by side, and a polyurethane foam filler conveying mechanism and a drying agent conveying mechanism are arranged at the front end of the gun body. The discharge speeds of the glue injection mechanism and the drying agent adding mechanism are simultaneously controlled by a discharge control mechanism. The polyurethane foam filler and the drying agent are efficiently mixed at a mixer jointly connected to the discharge ends of the polyurethane foam filler conveying mechanism and the drying agent conveying mechanism, and then sprayed out.

[0004] However, the following problem will occur during the use of this solution: since the device needs to fix the polyurethane foam sealant bottle on the device when in use, but the polyurethane foam sealant bottles have various sizes, and the device can only position and fix the polyurethane foam sealant bottle of one size, when the staff uses polyurethane foam sealant bottles of different sizes, the device cannot position and fix the polyurethane foam sealant bottles of different sizes, thereby reducing the adaptability of the device to a certain extent. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content
