Drive mechanism for fused mass milling degree regulating device of milling extrusion pressing granulation machine group

Abstract

The invention relates to a novel extruding granulation machine unit. In a device for regulating melt mixing degree of a mixing granulation machine unit, a material runner is arranged in a valve body; a rotatable valve core or a rotatable valve plate are arranged in the material runner and with the difference of a rotation angle, flow area of the valve core or the valve plate is different; the valve core or the valve plate are connected with a driving mechanism through a rotation shaft and the driving mechanism is connected with a reducer by a motor output shaft; the reducer is connected with the rotation shaft of the device for regulating the melt mixing degree. In the novel extruding granulation machine unit, the motor drives the reducer to drive the regulation device and the novel extruding granulation machine unit has a simple and compact structure, less parts; a diction function is brought into play by an angular displacement sensor fixed on the end of the shafts. As the motor can realize positive and reverse rotation, the angle can be changed at any time, which means the melt mixing degree can be changed with the advantages of timely and simple control. The reducer directly connected with the motor adopts a worm gear form to effectively realize self-locking and accurate location as well as avoid the rotation of the valve core caused by the material.

Description

1. Technical field [0001] The invention relates to a novel extruding and granulating unit, in particular to the driving mechanism of its melt kneading degree adjusting device. 2. Background technology [0002] The mixing extrusion granulation unit is one of the most important equipment for ethylene engineering in the petrochemical industry. The melt mixing degree adjustment device is one of the indispensable key components of the mixing extrusion granulation unit. Its main function is to control the mixing degree and material temperature according to different grades of materials and output. [0003] The rotation of the valve core or valve plate in the melt mixing degree adjustment device can be realized in various ways. Such as manual, hydraulic drive, etc. However, for large-scale equipment, the rotational torque of the valve plate is large, and it is inconvenient to operate manually; the hydraulic motor drive requires a stable supply of hydraulic oil, and at the same t...
