Environment-friendly glass fiber sleeve gluing and coating device

The invention relates to the technical field of glass fiber pipe production, in particular to an environment-friendly glass fiber sleeve gluing and coating device which comprises a shell, an extrusion pipe capable of sliding and displacing and a guide pipe containing and penetrating through a glass fiber pipe, the extrusion pipe is arranged on the peripheral side of the guide pipe in a sleeving mode, and a cavity for containing coating liquid is defined by the shell, the extrusion pipe and the guide pipe jointly. The guide pipe comprises an upper port and a lower port, a glass fiber pipe can enter the upper port through the upper port, the lower port is linearly communicated with the upper port, the lower port is coaxially connected with a nozzle assembly in a penetrating manner, the nozzle assembly comprises a pipeline and a spraying channel, the pipeline is communicated with the lower port, the spraying channel is communicated with the cavity, and the spraying channel surrounds the pipeline and is coaxially arranged. And when the glass fiber pipe is pulled out from the pipeline of the nozzle assembly, the silica gel coating liquid in the spraying channel is uniformly coated on the surface of the glass fiber pipe under the action of the gravity of the silica gel coating liquid.
