Powder-accumulation-prevention type hopper for sensor molding extruding machine

Abstract

The invention discloses a powder-accumulation-prevention type hopper for a sensor molding extruding machine. The powder-accumulation-prevention type hopper comprises a cylindrical material storage barrel, a frustum body connected below the material storage barrel and a hopper body connected below the frustum body and composed of a material discharging barrel, wherein the integral hopper body is in a cavity structure; the frustum body is at least provided with two air nozzles; the air nozzles are connected with a high-pressure air source by pipelines. According to the powder-accumulation-prevention type hopper for the sensor molding extruding machine, the high-pressure air source blows blocked powder by the air nozzles and the blocked powder can be dispersed by a very great air-pressure impact force so as to fall into the material discharging barrel and guarantee normal production; an inclined angle is formed by the nozzles and the side face of the frustum body and the nozzles are aligned to the top face of the frustum body so that the impact force of high-pressure air can be utilized to the greatest extent and the aim of blowing away of the powder is realized; the powder-accumulation-prevention type hopper for the sensor molding extruding machine is simple in structure and is convenient and practical.

Description

technical field [0001] The invention relates to a hopper of an extruder in the sensor manufacturing industry, in particular to a sensor forming extruder hopper for preventing powder accumulation. Background technique [0002] The automobile wheel speed sensor is mainly composed of induction head, wiring harness and accessories. The role of the induction head is to cooperate with the target gear installed on the chassis of the car to measure the speed of the car wheel, which is composed of coils, magnetic poles and other parts. On this basis, to ensure the normal operation of the sensor, the sensor must be properly installed on the chassis of the car, and there are many ways to install it. Now commonly used a kind of wheel speed sensor is to rely on the outer steel casing of the induction head to cooperate with a part, i.e. the elastic bush, and pack into the corresponding mounting hole of the chassis. When designing the sensor, it is necessary to combine the magnetic steel...
