Coating film peeling apparatus for resin material

Abstract

A coating film peeling apparatus for resin material includes: a peeling cylinder, a peeling roll installed therein with a space for a peeling process along an inner wall of the peeling cylinder, a resistance lid disposed to block a discharge port of the peeling cylinder, and a pressure adjustment part for adjusting an outflow rate and internal pressure of the peeling cylinder. The peeling cylinder is constituted by a polygonal-shaped angular columnar body having, as coating film pass-through holes, rows K of small holes and rows L of small holes and projection rings (angular embossments) provided alternately in multiple rows along a direction perpendicular to a rotating direction of the peeling roll.

Description

technical field [0001] The present invention relates to peeling off and removing the coating film of resin materials such as bad bumpers of vehicles or used bumpers of scrapped cars, and processing them as recycled materials into bumpers of new cars or resin parts for the treatment of resin Coating film peeling device for resin materials such as bumpers for material recycling. Background technique [0002] Conventionally, as a coating film stripping device for a resin material such as a bumper, a coating film stripping device for a resin material including a stripping cylinder with one end as a supply side and the other end as a discharge side is well known, and is arranged on the outer periphery. There are a plurality of protrusions, a peeling roller forming a gap for peeling treatment with the inner wall surface of the peeling cylinder, a pressing plate configured to close the discharge port on the discharge side of the above-mentioned peeling cylinder, and the size of the...

Problems solved by technology

That is to say, the square emboss 103 is a part provided for improving the cutting effect, and although there is no particularly large influence on the degree of passing the resin material through the coating film stripping device once, if it is to be passed through the coating film stripping device 4 to 5 times to completely remove the coating film, there is a problem that the recycling rate is deteriorated due to excessive cutting of the recycled material

In addition, regarding the above-mentioned long slit 102, for the plate-shaped polygonal resin material having a thickness of 4 mm or less, the resin material leaks from the long slit 102 in the peeling process, which becomes a factor of deterioration of the recovery rate.
