Description

TECHNICAL FIELD

The coating is a thin hot melt resin film formed by feeding the resin heated and extruded by a screw to a forming die, and then flowing and coating on a base material. Then, the base material and the coated resin are pressed into a composite film by an extrusion roller and a cooling roller. Finally, the composite film is wound into a roll by a winding device.

[0004] The above-mentioned comparative document points out that the aluminum-plastic composite tape glue coating device can spray glue from the nozzles in the storage box by starting multiple pressure devices, and can also start the first cylinder to tilt the nozzles to adapt to composite tapes of different widths. If the glue overflows, the glue will enter the collection groove during the rotation of the conveying belt, and the glue on the conveying belt can also be cleaned by the cleaning plate. However, the device does not have a coating and smoothing device, and only the glue is sprayed onto the composite tape by the nozzles, which makes it difficult to ensure the uniform distribution of the glue. Due to the pressure changes that may exist during the spraying process, the changes in the distance between the nozzles and the composite tape, and the unevenness of the composite tape itself, etc., it may cause the local glue to be too much or too little.
