The present invention relates to an automatic reaming machine of a blow molding container, and more particularly, to an automatic reaming machine of a blow molding container, which smoothly maps the outer circumferential surface of a large container such as a bottle of water to prevent leakage when the cap is closed. It is about.

The bottled water to be blow molded is formed with a very wide inlet and thick. In addition, since the injection hole is molded between the injection pin and the injection hole forming portion of the mold, small scraps easily occur due to resin leakage. It is difficult to maintain airtightness between the inlet outer peripheral surface and the cap inner surface with the cap closed, unless smoothly sandpapered before capping the outer peripheral surface of the inlet such as a bottle of water.

Conventionally, manual and semi-automatic reaming machines have been used as a method of mapping the outer circumferential surface of an injection port such as a bottle of water. Manual work is a method in which a worker rubs the outer circumferential surface of the inlet with sandpaper to finish it. Semi-automatic reaming machine attaches a reamer (grinding wheel) to the head of the table drilling machine instead of a drill, and the operator grasps the handle and lowers the reamer, thereby finishing the injection port outer peripheral surface. However, bottled water bottles, etc., are very large and require two or more workers to ream by hand, and there is always a risk of leaks because the surface of the inlet cannot be constantly mapped, resulting in long working hours. There is a problem of low productivity. Even in the case of finishing by the semi-automatic reaming machine, it is difficult to control the force or the depth of the operator, so that the surface of the inlet is not smoothly and uniformly mapped, and the work time is long, as in the manual work, and the productivity is low.

An object of the present invention is to provide a blow molding container automatic reaming machine capable of automatically and uniformly and smoothly mapped the outer peripheral surface of the inlet, such as bottled water, such as bottled water.
