Description
The utility model relates to a kind of equilibrium principle of utilizing multiplying lever realizes material automatically in conjunction with electronic switching circuit the fixed heavily device of weighing.It utilizes load-bearing lever and force transferring lever to come power transmission, and utilizes balanced weight and revise sliding weight and come weight at the bottom of balance and the revised version, makes it to have " putting 0 " function.Pay sliding weight balance packed article weight and be aided with electronic switch control with main, make it to constitute the heavy surely automatically accurately meausring apparatus of weighing, its structure and performance have accurately, easy distinctive feature.
Though the micro-processor controlled meausring apparatus of Chu Xianing is applied on the cement quantitative package machine in recent years,, adds its strong point of unfavorable factor such as dust pollution and be difficult to performance because low being difficult to of operator's educational level drives.Also still have its realistic meaning so utilize leverage to carry out weighing in this field." a kind of weighing device " that uses at cement-packing plant also utilizes leverage to measure at present.Its structure such as Fig. 1.Bar 1 is for the metering mobile jib or claim scale, is the scale of using 100 kilograms of platform balances, also has sliding weight 2 and fine setting stone roller 3 above, and right-hand member force B goes up and hangs certain heavy balanced weight 5, and about 1.4 kilograms, stone roller 2 and stone roller 3 about 100 grams, the arm ratio of bar 1 is 5:1.Bar 4 is load-bearing lever scales, and its arm is than being 10:1, and emphasis A ' locates to bear total weight, i.e. cement weight W(50 kilogram) and background weight Q
0, this Design of device thought is to use weight to be (Q
0+ W) the total arm ratio of 1/50(system is 5 * 10) balanced weight 5 and sliding weight 2 remove balance (Q
0+ W).Work as Q
0Necessarily, if system balancing, then cement W must be 50 kilograms, and actual conditions are really not so.Because cut or polish jade with an emery wheel 5 and the stone roller 2 balances be Q
0Weight sum with W.When not packing, promptly during W=0, stone roller 2 is moved on to " 0 " position of scale, system can not balance.So background weight can not be got rid of in the weighing process, it will cause direct influence to the accuracy of cement weight W.Facts have proved Q
0Change, it comprises steel construction carriage (acting on the same scale pan) and adorns the weight of a plurality of assemblies thereon, this Q
0One the same, and differ bigger.So even system reaches balance, cement weight W also changes, and is not equal to 50 kilograms.If consider the weight influence that dust stratification causes, the error of W is just bigger.The deviser may place hope on sliding weight 2 and fine setting stone roller 3.Cut or polish jade with an emery wheel 3 in light weightly, movable distance is little, and effect is little, and for sliding weight 2, then wants it play 4 effects: 1, to participate in balance (Q
0+ W).Defeated material should stop immediately when 2, system reached balance, but this process all lags behind, so the sliding weight 2 that will move to left makes system reach balance ahead of time, to guarantee the weight of cement, what moves will try next.3, be used to adjust cement weight in permissible error.4, balance dust stratification and export compelling forces such as grey impulse force.In fact sliding weight 2 is in light weight, and displacement is limited, does not play this many effects, and that just have to increase and decrease the weight of balanced weight 5.For each Q
0, must there be the weight of a balanced weight corresponding with it, must not change.In using at the scene, because the effect of dust stratification and external force, this increase and decrease is frequent, and we can see and hang weights such as nut, packing ring, galvanized wire on the balanced weight, be exactly this cause.According to operator's reflection, this installs unstable, adjusts trouble, can only try.The heavy qualification rate of bag does not increase yet, and this is the greatest drawback of this device.
Secondly, owing to structural reason, the load-bearing lever design becomes arm than 10:1,35 millimeters of weighing arms, 350 millimeters of the arm of forces.35 millimeters spacing is littler concerning the hanger of 100 kilograms of platform balances, and the friction of two hangers often takes place, and influences operate as normal, so the relevant part that can only take to grind off hanger is solved.
Its three, the load-bearing lever arm ratio is 10:1, causes fulcrum F ' stressed excessive, reaches 90% of total weight, has the blade of 1 mm wide if it is calculated that knife, then the maximum contact stress of the every centimetre length of knife is up to 2800～3500 kilograms.So big frictional resistance increases wearing and tearing, and is totally unfavorable to weighing.
The utility model " heavy surely automatically meausring apparatus " (seeing accompanying drawing 2) has been avoided above-mentioned weak point of the prior art and a kind of new meausring apparatus is provided.Its leverage are by shell load-bearing lever 4, and force transferring lever 8 and metering mobile jib are formed.The metering mobile jib is made of a main scale 11 and a pair scale 13.Force transferring lever is all different with aforesaid measuring apparatus with the metering mobile jib that is made of double scale.Knife 7 is housed on each lever, and the cutter that is supported on hanger 6 by it holds on 5, and the fulcrum of lever hangs on the crossbeam 14 by hanger.Connect by hanger between each bar, total weight by link up with 3 and hanger act on the emphasis of load-bearing lever.Each bar all can freely swing.Load-bearing lever left end is established and is revised sliding weight 1, and the main scale left end is established balanced weight 15, and the main scale the right of paying is established main sliding weight 10 and paid sliding weight 12.Electronic switch 9 is installed in main sliding weight top.
Because the background weight error is bigger, it causes adverse effect to the actual weight of packed article, therefore should get rid of in the weighing process.So this device has designed " putting 0 " function, does not promptly only have under the situation of background weight there being packed article weight, will lead a pair sliding weight and place left " 0 " position, move again and revise sliding weight, lever is in the situation that equilibrium state is equivalent to scale.At this moment this device only need measure the weight of packed article.This is one of its advantage.
Since main sliding weight balance the major part of weight of packed article, pay its little part of a sliding weight balance, so it is less to pay the sliding weight Moving Unit weight that distance is adjusted, can reach the purpose of fine tuning, this structure is gone the mode of balance background weight and packed article weight sum with a big balanced weight than " a kind of weighing device ", want much superior, this be it advantage two.
The utility model is provided with force transferring lever 8, and its effect is the arm ratio that has reduced the load-bearing lever, and shortens its physical dimension.Bring two big benefits thus, can strengthen the distance of emphasis and fulcrum, avoid hanger to rub mutually, improved the force-bearing situation in fulcrum and force.Can slow down wearing and tearing like this, reduce frictional resistance, improve the sensitivity and the serviceable life of measuring apparatus.This be it advantage three.
The utility model is provided with electronic switch 9.When the main sliding weight of paying is in scale limit on the right-right-hand limit position, to mark system and reach balance, this moment, the weight of packed article reached setting just.At this moment the scale right-hand member is upwards kicked up gradually with heeling condition, when being up to the standard state (this moment thick stick be balance), switch 9 conductings, the defeated material of electric control gear work stops at once, has guaranteed the fixed heavily accuracy of weighing, this be it advantage four.
Enforcement of the present utility model is applicable to quantitative package machinery, especially cement-packing plant or other powderies, particles packing machine.It will improve the accuracy of measuring, and very convenient to use.The operator only need do two things: 1, will lead and pay a sliding weight and move left to " 0 " position, and move and revise sliding weight, the horizontal line of main scale right-hand member is alignd with pointer on the casing, scale is in horizontality at this moment.Transferring " 0 " promptly to accuse finishes.Master, pair sliding weight move to right afterwards to extreme position, fixing main sliding weight and correction sliding weight.2, owing to being conducting to defeated material, ends by electronic switch, one mistiming was arranged, it is hysteresis quality, need move to left little sliding weight to avoid weight overproof, it is suitable what move to left, and can solve so easy operation by twice actual measurement, even the workman that educational level is very low also can use, so this device has very big practicality.
