Abstract

The invention provides a switching device for reducing the air break resulted from powder particle entering into body box and change-over valve without maximizing the device and increasing the price. The invention comprises: body box (14.15a), two upstream side peristomes (40A.40B), downstream side peristome (50A), shift-type tabular change-over valve (11) for switching the two upstream side peristomes and driving mechanism (16) for driving the shift-type tabular change-over valve. The shift-type tabular change-over valve is equipped with two occlusive parts (11b.11b) and body size hole (11a) in the middle along the shifting direction and shifts along the direction approximately perpendicular with air transport channel(20A.20B.30) using the driving mechanism. When one side of the upstream side peristome is obturated using any occlusive part, the body size hole will integrate with the other side of the upstream side peristome to make the air transport channel connected with the peristome connect with the air transport channel of the downstream side.

Description

technical field [0001] The present invention relates to a conversion device that is arranged in an air conveyance channel for powdery or granular materials such as synthetic resin raw materials, and allows two systems of air conveying channels corresponding to two types of powdery or granular materials to be mixed and merged into one system of air conveying channels. Background technique [0002] Conventionally, a pulverizer is used to pulverize waste resins such as gates and runners that accompany synthetic resin molding, and mix the pulverized materials with unused new materials to mold various synthetic resin products. [0003] With this process, waste resin can be reused while maintaining quality to a certain extent, thereby reducing costs. [0004] However, in the above-mentioned process, in order to ensure the quality of molded products, crushed materials and unused new materials need to be mixed at a certain ratio. The bulk material is respectively transported from t...
