Description

Paper coating equipment {Apparatus for coating paper pipe}

The present invention relates to a paper tube coating apparatus, and more particularly, to a paper tube coating apparatus for coating the both sides and the inner surface of the paper tube wound the sheet, and processing the inner end of the paper tube.

In general, the paper tube is a cylindrical tube for rolling papers or resin films in a rolled state, and is spirally wound in a cylindrical shape stacked by stacking a plurality of papers having different widths. The bonding force is maintained by the adhesive.

These tubes are cut to length to suit the application. Both edges of the cut edges are sharp, and the remaining edges of the paper are not completely cut, or the edges of the cut edges are rough, so that the cut edges are polished smoothly.

If the cut surface is rough and foreign matter remains, it is generated in the film production process produced in a clean room, and a stake is generated and becomes a defect factor of the film.

In general, when cutting a paper pipe, the knife is inserted from the outside while the paper pipe is rotated fixed to the shaft, and the tip is cut inside the paper pipe. Doing.

In other words, foreign material such as paper debris that is not properly cut still remains in the corner where the inner diameter of the paper pipe meets the hollow (paper pipe cutting corner) .If the cutting surface is not cut well, the cause of equity is not eliminated even by polishing. As it is removed with a knife one by one, the risk of a safety accident and a separate worker is required.

And, in order to reduce the equity generated from the branch pipe is used to apply a coating liquid to the outside of the branch pipe to dry, but the coating of the inner surface to define the hollow of the branch pipe is implemented, but the branch pipe cut surface is not coated, generated from the branch pipe cut surface There was a problem that could not be removed.

In addition, due to the limitation of the technology of coating the coating solution evenly on the outer surface of the paper tube and drying the coating solution, there is a problem of deteriorating the quality of the paper pipe because the coating solution cannot be coated evenly and uniformly.
