Problems solved by technology
[0003] However, when the high-pressure gas inside the molded preform is discharged, it is discharged through a single vent hole. Due to the drastic change of the gas pressure at the nozzle, pressure waves are generated in the air and in the exhaust pipe, thereby radiating strong noise; At the same time, the vertical gas discharge method will cause serious damage to the side wall of the vent hole of the die head

The invention discloses a discharge device for bottle blowing gas in a rotary bottle blowing machine. A hollow exhaust column is inserted in the die head, and the outer circumferential array of the exhaust column is provided with multiple rows of exhaust holes, and the exhaust holes on the same horizontal plane are fixedly connected with row Air pipe, and one of the exhaust pipes is fixedly connected with a communication pipe leading to the bottom of the exhaust column, the lower end of the exhaust column is provided with a push-pull valve, and the exhaust column is rotatably connected to the side wall of the push-pull valve It is provided that an electromagnet is arranged on the bottom end surface of the die shoulder, and a magnet corresponding to the electromagnet is arranged on the upper end surface of the push-pull valve. The present invention relates to the technical field of bottle blowing equipment. The device can uniformly reduce the pressure and discharge the high-pressure gas inside the preform, and effectively prevent the preform from being deformed during the exhaust process.
Description
technical field [0001] The invention relates to the technical field of bottle blowing equipment, in particular to a blowing gas discharge device in a rotary bottle blowing machine. Background technique [0002] Rotary blow molding machine: through setting several blow molding stations at intervals on its rotary mechanism, each blow molding station is equipped with a mold and a high-pressure valve. After heating, the preform is sent to the blowing platform. Then clamp the mold, successively undergo low-pressure blowing, and then high-pressure blowing, that is, the high-pressure gas of the blowing bottle enters the preform in the mold through the high-pressure valve, and the high-pressure gas inside the molded bottle cavity is exhausted through the high-pressure valve. mouth out. [0003] However, when the high-pressure gas inside the molded preform is discharged, it is discharged through a single vent hole. Due to the drastic change of the gas pressure at the nozzle, pressur...
