In the polishing machine, the pellets separated by the separation gutter are stored in a pellet receiving tank through the pellet introduction pipe, a solvent is mixed into the stored pellets, and the pellets are lifted up through a washing cylinder installed vertically in the pellet receiving tank. Wash while stirring,
A pellet reflux pipe is provided to return the washed pellets sorted by the sorting gutter provided in the washing cylinder to the tank of the pachinko ball polishing machine, and the dust separated from the pellets during stirring and pumping in the washing cylinder is transferred to the washing cylinder. The blower has a suction port for collecting dust through a dust collection pipe from a notched slit to a filter provided in the dust collection box, and a discharge port for sending warm air for drying the pellets to the pellet receiving tank. The present invention is characterized in that clean and dry pellets are always supplied to the pachinko ball polishing machine.

(Function) In this invention, cleaned pellets are introduced from a pellet reflux pipe into a tank where dirty pachinko balls flowing in from a ball reflux gutter are stored, and are mixed and agitated in the tank before being pumped to a polishing tube. In the pachinko ball polishing machine, the pachinko balls that have been separated and polished by the separation gutter are supplied to each pachinko machine from the ball return pipe.A solvent agent is applied to the pellets that are separated by the separation gutter and introduced into the pellet receiving tank by the pellet introduction pipe. The pellets and the solvent are separated by a sorting trough. The clean pellets separated by the sorting gutter are returned to the tank of the pachinko ball polishing machine through the pellet return pipe, and the above-mentioned series of steps are continued. When the pellets are agitated and cleaned in the cleaning cylinder, the dust separated from the contaminated pellets passes through the slit in the cleaning cylinder and is sucked and removed by the blower through the dust collection pipe and the filter in the dust collection box. In addition, the hot air discharged from the blower is sent to the bottom of the pellet receiving tank and contributes to drying the pellets, so when the pellets are stirred and pumped in the cleaning cylinder, they are effective in easily separating the dirt adhering to the pellets. It is played.

(Example) In this example, the pellets used to polish pachinko balls refer to plastic pellets, which are granular intermediate products manufactured from petroleum and used as raw materials for molding plastic products. In the example, nylon plastic pellets were used.

The solvent for cleaning the pellets is slightly larger than the pellets and smaller than the pachinko balls, such as rice husks, sawdust, activated carbon, zeolite, etc., or molded products thereof, and is hard enough not to scrape the surface of the pellets. It is better to have it molded into
In this example, paulownia sawdust was solidified by adding an organic industrial chemical.
