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
The present invention relates to the hopper of extruding machine in sensor manufacturing, specifically refer to the sensor moulding extruder hopper that prevents that powder from piling up.
Background technology
Automobile wheel speed sensor is mainly comprised of inductive head, wire harness and annex etc.The effect of inductive head is exactly to coordinate with the target gear being contained on automobile chassis, and the rotating speed of measured automobiles wheel, is partly comprised of coil, magnetic pole etc.On this basis, guarantee normal operation of sensor, also must make sensor reasonably be installed on automobile chassis, its mounting means has a lot.Existing normally used to have a kind of wheel speed sensors be steel shell and a part that relies on inductive head outside, i.e. resilient bushing cooperation, packs in the corresponding mounting hole of chassis.During design sensor, in the middle of magnet steel, magnetic conductor need to being combined in, magnetic conductor is an iron core, and coil, around magnet steel and iron core, forms magnetic conduction coil.The variation of the coil-induced surrounding magnetic field of magnetic conduction, produces the signal of telecommunication, and this signal of telecommunication outputs to external device (ED) by capillary.The supporting mass of magnet steel, iron core, coil is called skeleton.Existing skeleton is split type skeleton, first needs injection moulding one skeleton body, reinstalls iron core, magnet steel, finally reinstalls stopper, forms skeleton; The technical process that forms sensing head is as follows: 1, processing parts: skeleton body, magnetic conductor, magnet steel, capillary, stopper, coil, cotton thread; 2, assembling process: iron core gluing packs skeleton body-coiling-twine cotton thread-dress magnet steel-stopper gluing assembling-coil the end of a thread line tail to be wound on capillary into.
The raw material of extruding machine has multiple, wherein has the unfixed solid material of particulate material, powder and shape.Because the characteristic of powder is different from other material, in use, there will be solid accumulation in various degree, particularly material is not used through piling up for a long time, under the effect of self gravitation, material is extruding mutually, forms whole, easy bonding one-tenth bulk in the situation that running into water vapour or water particularly, and vibration easily bonding, vibrate more severe, bonding must be tighter, thereby cannot fall, cause cannot normally producing after start.
Summary of the invention
The object of the present invention is to provide the sensor moulding extruder hopper that prevents that powder from piling up, solve powder in current extruder hopper and after long-time extruding, form caking, cause the problem that cannot use, reach the object that solves at any time powder caking.
Object of the present invention is achieved through the following technical solutions:
Prevent the sensor moulding extruder hopper that powder is piled up, comprise by columned material stock cylinder, be connected to material stock cylinder below cone table, be connected to the hopper body that the discharge barrel of cone table below forms, hopper body integral body is cavity structure, two air nozzles are at least installed on described cone table, and air nozzle is connected with high-pressure air source by pipeline.The hopper body of extruding machine mainly consists of three parts: material stock cylinder, cone table, and discharge barrel, material stock cylinder integral body is cylindric, its inside is cavity structure, it has two end faces the sidewall that cone table is two circles of connection, two end faces are circle, its center of circle is positioned on the axis extended line of material stock cylinder, wherein, the nose circle face that radius is larger is connected with material stock cylinder, the nose circle face that radius is less is connected with discharge barrel, discharge barrel integral body is also cylinder, material stock cylinder, cone table, and the axis of discharge barrel is all on same straight line, during use, material stock cylinder be positioned at top and discharge barrel be positioned at below, oblique supporting role due to cone table, will inevitably cause powder extruding mutually under Action of Gravity Field, long-term extruding and don't athletic meeting cause the bonding one-tenth of powder whole, so, air nozzle is installed on cone table, air nozzle is connected with high-pressure air source by pipeline, when powder has some setbacks from discharge barrel discharge, pass through magnetic valve, high-pressure air source blows to the powder of caking by air nozzle, air pressure impulsive force can will become the powder of piece to break up greatly, thereby fall into discharge barrel, guarantee normal production.
Described air nozzle is four, and is evenly distributed on cone table side.By four equally distributed nozzles are set, nozzle and formation inclination angle, cone table side, nozzle, over against the end face of cone table, can maximally utilise the impulsive force of gases at high pressure, reaches the object that dispels powder.
The junction of described material stock cylinder and cone table and cone table and discharge barrel is smooth curved surface.Further, in order to reduce the accumulation of powder in hopper body, the form that the junction that adopts material stock cylinder and cone table and cone table and discharge barrel is smooth surface, can reduce the impetus that powder retains, effectively prevent the accumulation of powder, because material stock cylinder and cone table and cone table and discharge barrel all adopt the form of Plate Welding, conventionally after welding completes, for weld seam and weld edge, carry out grinding process, make its smooth surface, edges and corners become curved surface.
The present invention compared with prior art, has following advantage and beneficial effect:
1 the present invention prevents the sensor moulding extruder hopper that powder is piled up, air nozzle is installed on cone table, air nozzle is connected with high-pressure air source by pipeline, when powder has some setbacks from discharge barrel discharge, pass through magnetic valve, high-pressure air source blows to the powder of caking by air nozzle, air pressure impulsive force can will become the powder of piece to break up greatly, thereby fall into discharge barrel, guarantee normal production, nozzle and formation inclination angle, cone table side, nozzle is over against the end face of cone table, can maximally utilise the impulsive force of gases at high pressure, reach the object that dispels powder;
2 the present invention prevent the sensor moulding extruder hopper that powder is piled up, the form that the junction that adopts material stock cylinder and cone table and cone table and discharge barrel is smooth surface, can reduce the impetus that powder retains, effectively prevent the accumulation of powder, because material stock cylinder and cone table and cone table and discharge barrel all adopt the form of Plate Welding, conventionally after completing, welding carries out grinding process for weld seam and weld edge, make its smooth surface, edges and corners become curved surface, simple in structure convenient and practical.
