Tablet press machine for injecting plastic, detection system and detection method using the tablet press machine

Abstract

The invention relates to a tablet machine capable of ejecting plastic, which is used for pressing plastic particles into thin flake-shaped plastic sheets. The tablet machine comprises a machine platform, a heater, a material holding platform and a pressurizing module, wherein the heater is mounted on the machine platform and is used for heating the material holding platform; the material holding platform comprises a mold cavity used for containing to-be-ejected plastic particles; the pressurizing module is located above the material holding platform; the pressurizing module comprises a pressure cylinder and a pressurizing plate which is mounted below the pressure cylinder and at a position corresponding to the mold cavity; the pressurizing plate can move between a molding position and a preparation position; when the pressurizing plate is located at the molding position, the thin flake-shaped plastic sheets are formed and can admit light, so that the advance detection of to-be-ejected plastic is facilitated. Through the material holding platform, the heater and the pressurizing module, the manufacturing of the thin flake-shaped plastic sheets is completed, the defect spots of the thin flake-shaped plastic sheets are analyzed by an optical sensing unit and a logic operation unit, and whether the thin flake-shaped plastic sheets meet a criterion of acceptability is judged, so that the detection of the to-be-ejected plastic is completed in advance.

Description

Technical field [0001] The invention relates to a tablet press, in particular to a tablet press for injecting plastic and a detection system and a detection method using the tablet press. Background technique [0002] In the past, when plastic injection molding was performed, the pelletized plastic was heated and melted and then the liquid plastic was injected into the mold to cool the molded product. However, due to the uneven quality of the plastic pellets, the impurities in the plastic pellets It causes defects such as black spots or stains on the surface of the product, which reduces the yield of the product. [0003] Therefore, a plastic injection tablet press that can detect the injected plastic in advance, and a detection system and detection method using the tablet press are currently required by the market. Summary of the invention [0004] The object of the present invention is to provide a plastic injection tablet press that detects the injected plastic in advance, and a...
