Automatic feeding system for medium-voltage shielding materials

Abstract

The invention belongs to the field of medium-voltage shielding material production, and particularly relates to an automatic feeding system for medium-voltage shielding materials. The system involvesa material barrel, a feeder, a negative-pressure conveying device and a metering device used for feeding of a mixing mill and reciprocating machine combination; the materials are placed in the material barrel, the discharging end of the material barrel is connected with the feeder, the feeder is connected to the negative-pressure conveying device through a conveying pipeline, the discharging end of the negative-pressure conveying device is connected with the metering device, and the discharging end of the metering device is connected to the mixing mill and reciprocating machine combination; automatic transformation of "internal mixer and reciprocating machine" combination feeding is achieved, and the frequency of accidental errors is reduced; the problems of labor intensity and environmental sanitation of an operator for producing the shielding material by using an internal mixer are solved; a foundation is laid for traceability of big data acquisition and product quality management ofproduced medium-voltage shielding material products; and the management standard level of process and operation is improved, and variety replacement is fast, convenient and accurate.

Description

technical field [0001] The invention relates to the field of production of medium-voltage shielding materials, in particular to an automatic feeding system for medium-voltage shielding materials. Background technique [0002] There are basically two combinations of traditional shielding material equipment in China: "internal mixer + single screw combination" and "measurement scale + reciprocating machine combination". The traditional "measurement scale + reciprocating machine combination" basically realizes the accurate measurement of material components And continuous supply, but neither the "internal mixer + single screw combination" nor "internal mixer + reciprocating machine combination" has realized the automatic transformation of the feeding system, and all are added by manual weighing. [0003] There are following problems in prior art: [0004] In the process of producing medium-pressure shielding materials with traditional internal mixers, there are problems such a...
