Further, in the fifth step, the hot air which is not in contact with the lower wind deflector flows to the blanking chamber along the bottom of the blast forming chamber.

In the eighth step, when the feedback monitoring sensor detects that the solid bottle chips are refluxed into the blowing pipeline, the feedback monitoring sensor feeds back signals to the air guide motor, so that the driving air guide plate and the driven air guide plate form a feedback baffle, the refluxed solid bottle chips are blown clean through rotation of the wind direction adjusting mechanism, and then the feedback monitoring sensor feeds back signals detected to the solid bottle chips to the air guide motor, so that the driving air guide plate and the driven air guide plate form an air guide channel; the wind-guiding motor is used for controlling the driving synchronous belt pulley and the driven synchronous belt pulley to synchronously rotate, when the wind-guiding motor positively rotates, the driving wind-guiding plate and the driven wind-guiding plate form a positive wind-guiding channel, and at the moment, the wind-direction adjusting mechanism positively rotates; when the wind-guiding motor reversely rotates, the driving wind-guiding plate and the driven wind-guiding plate form a reverse wind-guiding channel, and at the moment, the wind direction regulating mechanism reversely rotates; the wind blown by the blowing fan is combined with the wind generated by the forward rotation of the wind-guiding motor after passing through the forward wind-guiding channel, and the wind blown by the blowing fan is combined with the wind generated by the reverse rotation of the wind-guiding motor after passing through the reverse wind-guiding channel; and then the solid bottle flakes are blown into the storage bin.
