This invention provides an electric adjustment device for the die opening gap of an extrusion blow molding machine, comprising a motor, a belt, a reversing device, a reducer, a coupling, a ball screw pair, a thrust roller bearing, a sleeve, and a mandrel.
The belt is a synchronous belt. The reversing device is a clutch reversing device, comprising two input end caps and an output shaft.
The two input end caps are respectively connected to two motors via the synchronous belt. The output shaft is connected to the input end of the reducer.
The output shaft of the reducer is connected to the ball screw via a coupling. The sleeve includes a grooved sleeve and a sleeve with a cross-slider.
The thrust roller bearing is installed in a step at the upper end of the grooved sleeve. The grooved sleeve and the sleeve with the cross-slider are coaxially mounted.
The two ends of the sleeve with the cross-slider are respectively connected to the mandrel and the nuts of the ball screw pair.
This invention also provides a method and application for implementing the above device.
This invention has advantages such as high transmission efficiency, accurate positioning, environmental friendliness, compact and reliable structure, and rapid response, making it suitable for widespread use in industrial production.
