Abstract
The utility model relates to a microscale material feeding machine which comprises a packing auger, a speed reducing motor connected with a screw rod of the packing auger, a material cylinder arranged on the packing auger, a vibration device and a control device. The utility model is characterized in that a discharge opening at the bottom of the interior of the material cylinder is provided with a material cone which is an inverted cone. The cone angle of the cone is equal to the cone angle of the feed opening of the material cylinder, and the material cone is connected with the inner wall of the bottom of the material cylinder via rotary screws. The utility model has the advantages of uniform adjunction and stable and accurate feeding. The utility model which eliminates the material feeding error of different material positions in the material cylinder is especially suitable for adding additive with poor flowing performance.
Description
The utility model belongs to a kind of feeder, especially relate to a kind of micro-feeder, the trace feeder can be used for industry trace such as powder process, food, feed and adds mineral matter, vitamin and other solid, powdery, granular material, is particularly useful for the even feeding of the material of free-running property difference.
At present, the trace feeder mainly is divided into two classes: a kind of is by drive of motor machinery feed, another kind is the electric and magnetic oscillation feed, thyristor speed control, wherein for example: YUS series Trace feeder, from condition of service, effect is not ideal enough, mainly show: 1, feed is inhomogeneous, for the material of free-running property difference, and easy caking, putty; 2, the feed instability is inaccurate, and especially different material level feed errors are big in barrel.
The purpose of this utility model is to provide a kind of feed evenly and invariably with the micro-feeder of material level feed error.
The purpose of this utility model is to realize like this, a kind of micro-feeder, comprise auger, the reducing motor that links to each other with the auger screw rod, be contained in barrel, oscillatory system, control setup on the auger, barrel inner bottom part discharging opening is installed a material awl, the material awl is inverted cone, the cone angle of cone equates that with the cone angle of barrel feed opening the material awl is connected by rotary screw with the barrel bottom interior wall; Oscillatory system is the fixing dither motor of barrel outer wall, and the oscillation frequency of dither motor is 1400-2800Hz.
The utility model can be regulated material awl height by rotary screw and regulate the gap of barrel with the material awl, before discharging, set gap length earlier, make additive fall to auger by the gap of setting, can make blanking even like this, eliminated the feed error of different material levels in the barrel simultaneously, made feed accurate, stable; High-speed electric expreess locomotive drives barrel and produces vibration, and additive is evenly fallen under vibration, especially to the additive of free-running property difference, and sticking wall, putty not, feed is stable.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of embodiment;
Figure 2 shows that the automatic-control block diagram of embodiment.
Embodiment: form by barrel 1, vibrating motor 2, material awl 3, auger 7, reductor 12, frequency converter 13, controller 14, flow detector 11,15.Barrel 1 is positioned at auger 7 tops, and material awl 3 is installed in the bottom in the barrel 1; Material awl 3 is the inverted conical body, the cone angle of cone equates with the cone angle of barrel 1, material awl 3 is connected by rotary screw 1 with barrel 1 bottom interior wall, be fixed with the high frequency motor 2 that shakes at barrel 1 outer wall, on barrel 1 installation and the base 5, the thick rubber plate of one deck 3mm 17 is arranged between base 5 and the barrel 1, the funnel position 9 of barrel 1 bottom, insert in the auger 7 top inlet points 10, auger 7 is made up of cylindrical shell 6, quantitative screw rod 8, reducing motor 12, a webge slot 16 is driven on cylindrical shell top, and quantitatively screw rod 8 is positioned at cylindrical shell 6 inside, can move along cylindrical shell 6 directions; Screw rod 8 links to each other with reducing motor 12, drive the rotation of screw rod 8 by reducing motor 12, helicallobe rotation promotion additive is moved to the other end by cylindrical shell 1 one ends on the screw rod 8, the velocity of rotation of reducing motor 12 is controlled by the frequency converter 13 that is attached thereto, mass flow detector 15 is installed on the material production line, additive stream amount detector 11 is installed in discharging opening 10 places of feeder, controller 14 also respectively with mass flow detector 15, additive stream amount detector 11 links to each other, mass flow detector 15 and additive stream amount detector 11 detected signals are transferred to controller 14 respectively, controller 14 is according to predefined additives ratio, send control signal for frequency converter 13, adjust reducing motor 12 rotating speeds, the control addition, it is stable to reach adding proportion, purpose accurately.
Claims (3)
1, a kind of micro-feeder, comprise auger 7, the reducing motor 12 that links to each other with auger screw rod 8, be contained in barrel 1, oscillatory system 2, control setup 11,13,14,15 on the auger, it is characterized in that, barrel 1 inner bottom part discharging opening 10 is installed a material awl 3, material awl 3 be inverted cone, and the cone angle of cone equates with the cone angle of barrel 1 feed opening, expects to bore 3 and is connected by rotary screw 4 with barrel 1 bottom interior wall.
