Abstract

The utility model discloses the technical proposal of a weighing apparatus for quantitatively packing and for weighing the materials with large specific gravity, small granularity and good flowability. The scheme is characterized in that the weighing apparatus has a large and a small two feeders and a large and a small two material loading hoppers which are correspondingly connected with the feeders. The feeder is fed by the feeding groove on a material dispensing roller. The material loading door of the material loading hopper is a spherical shell body. A concave groove corresponding to a material discharge opening is processed on a material discharging door below a weighing hopper.

Description

Weighing apparatus for quantitatively packing

The utility model relates to weighing equipment, especially cooperate the ration package scale that is used for quantitative package with packaging machine.

In the existing quantitative packing scale, no matter what adopt is any feed-types such as gravity, vibration, spiral or belt transmission, contrast great, granularity is little, when the material of good fluidity carries out weighing, all exist to leak and expect and the inaccurate problem of weighing.

The purpose of this utility model is exactly at the existing in prior technology problem, and the ration package scale technical scheme that a kind of suitable contrast is great, granularity is little, the material of good fluidity carries out weighing is provided.

This programme is realized by following technical measures.Connect batchers and cut a hopper by hopper 3, have again, the ration package scale that has the discharge door 10 by cylinder 8 controls to be constituted at discharge gate 9 places of the hopper 7 of weighing by the LOAD CELLS 6 liftings hopper 7 of weighing.The special character of this programme is, described batcher is made up of little batcher 2 and big batcher 4, and little batcher 2 and big batcher 4 all are that a housing 14 with feeding mouth 13 and discharging opening 17 is arranged, the inner chamber of this housing 14 is a cylindrical cavity, in the cylindrical cavity of housing 14, the material toggling roller 15 that is mated is housed, the rotating shaft 12 of this material toggling roller is stretched out outside the housing 14, on the external cylindrical surface of material toggling roller 15, have three equally distributed feeder troughs 16 at least along face of cylinder bus; And described section hopper is made up of little section hopper 1 and the big hopper 5 that cuts, and little section hopper 1 all is made up of the bin gate 20 that cuts that rocking bar 18 is connected with its opening part guide tube 19 with the big hopper 5 that cuts, this section bin gate 20 is spherical shells, when a section bin gate 20 was in closed condition, the openend of guide tube 19 was lower than section bin gate 20 spherical shell open ends; On the discharge door 10 of described discharge door 10 and discharge gate 9 contact positions, have groove 22.This programme also has following concrete characteristics, promptly have equally distributed four feeder troughs 16 on the external cylindrical surface of described material toggling roller 15, and this feeder trough 16 is cylinder arch grooves.In the described groove 22 plasticity sealing gasket 21 is housed also.What the plasticity sealing gasket of being adorned in groove 22 21 adopted is rubber slab.

The ration package scale that adopts above-mentioned technical characterictic to constitute.Because batcher and cut a hopper and all form by large and small two, two batchers are worked simultaneously when normal feed.To near given weight the time, big batcher stops feed, and the continuous big hopper that cuts cuts out, then only by the feeder trough feed of little batcher, and the may command delivery rate.When reaching quantitative, little batcher stops feed, and little section continuous hopper cuts out, and so guaranteed the feed precision.And section bin gate of two-section hopper is a spherical shell, and when a section bin gate was closed, the open end of spherical shell was higher than the discharge port end of guide tube.This structure when cutting a bin gate and close, contrast great, granularity is little, the material of good fluidity, even if material overflows to some extent, also the spherical shell that is exceeded surrounds, and makes material be unlikely to fall into the hopper of weighing, thereby has guaranteed weighing precision.In addition, on the discharge door at the discharge gate place of the hopper of weighing, owing to be processed with groove, be added in the plasticity sealing gasket is housed in the groove, this just can not leak the material that enters the hopper of weighing, and also is the measure that guarantees weighing precision.This shows, the utility model compared with prior art, its effect is conspicuous.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the structural representation of batcher in the present embodiment;

Fig. 3 is the structural representation that cuts bin gate in the present embodiment;

Fig. 4 is that the A of Fig. 1 is to enlarged diagram.

Below by a specific embodiment and in conjunction with its accompanying drawing, the utility model is further elaborated.Ration package scale has hopper 3, two batchers that are connected in parallel under it, a big batcher 4 and a little batcher 2.Two batchers vary in size, but its structure is identical, all be that a housing 14 with feeding mouth 13 and discharging opening 17 is arranged, the inner chamber of this housing 14 is a cylindrical cavity, in the cylindrical cavity of housing 14, the material toggling roller 15 that is mated is housed, the rotating shaft 12 of this material toggling roller is stretched out outside the housing 14 and is connected with gear train, on the external cylindrical surface of material toggling roller 15, have four equally distributed feeder troughs 16 along face of cylinder bus.What connect with two batchers is large and small corresponding with it big section hopper 5 and little section hopper 1.The two-section hopper also is except that the size difference, structure also is identical, all form by the bin gate 20 that cuts that rocking bar 18 is connected with its opening part by guide tube 19, this section bin gate 20 is spherical shells, when a section bin gate 20 was in closed condition, the openend of guide tube 19 was lower than section bin gate 20 spherical shell open ends.Correspondence is the hopper 7 of weighing that is lifted by LOAD CELLS 6 below section bin gate 20 of two-section hopper, the discharge door 10 of being controlled its open and close by bin gate cylinder 8 is arranged at discharge gate 9 places of the hopper 7 of weighing, and on the discharge door 10 of discharge door 10 and discharge gate 9 contact positions, have groove 22, the rubber slab as plasticity sealing gasket 21 also is housed in groove 22.Below discharge door 10, be exactly the packing hopper 11 of packaging machine.So constituted the described ration package scale of the utility model.If structure of the present utility model adopts system controlled by computer, then can constitute full automatic electronics automatic quantitative packing machine.
