Abstract
The invention discloses a feeding measuring method for a feeding machine and a feeding system. The method comprises the following steps of establishing a balance system by adopting a balance principle; directly weighing the real-time mass of powder in the feeding machine; and calculating the real-time change of the powder mass to calculate the real-time feeding amount of the feeding machine. The system comprises a feeding machine, a counter weight, a balance arm, a cutting edge and a weighing sensor, wherein the balance arm is arranged on the cutting edge; the feeding machine is arranged on one side of the balance arm, and the counter weight is arranged on the other side of the balance arm; and the weighing sensor is arranged at the lower end of the feeding machine. The feeding measuring method and the feeding system have the beneficial effects that in an adopted balance method, the mass measured by using the weighing sensor is the mass of the powder from which the dead weight of the feeding machine is removed, and the net weight of the powder can be measured directly, so that the measuring range of the weighing sensor can be shortened greatly, the effective accuracy of the weighing sensor is increased, the feeding amount of a micro feeding machine with 'small tare weight' is measured accurately, the measuring range of the measuring sensor is shortened, the measuring accuracy is increased, and the measuring problem of the feeding machine with a micro feeding amount and small tare weight is solved effectively.
Description
Technical field
The present invention relates to the automatic measurement technology field, particularly relate to a kind of batcher feed measuring method and feeding system.
Background technology
In the existing feed weighing technique, mainly contain following several:
The impulse type weighing: German E+H company and Japan three Co., Ltd. of association mainly adopt this technology, and domestic a lot of producers introduce or adopt this technology.This technology response speed is fast, is moment formula continuous coverage.
The weight-loss type weighing: major part adopts this method now both at home and abroad, and to big flow measurement, this method is measured quick, the precision height.
More than two kinds of methods be applicable to the batcher that feeding coal is bigger.Very little for feeding coal, perhaps the batcher of " the tare weight amount is little " uses above two kinds of methods, and its measuring accuracy is very low, almost can't measure.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of batcher feed measuring method and feeding system, the feeding coal that solves micro-batcher or " the tare weight amount is little " batcher is measured problem.
The technical solution adopted in the present invention is: a kind of batcher feed measuring method, adopt equilibrium principle, set up a balanced system, directly the real-time quality of powder in the scale feeder, by calculating the real-time change of powder quality, calculate the real-time feeding coal of batcher.
A kind of batcher feeding system of the present invention, it comprises batcher, counterweight, balance arm, cutting edge, LOAD CELLS, and described balance arm places on the cutting edge, and a side arranges batcher, and opposite side arranges counterweight, and the lower end of batcher is provided with LOAD CELLS.
Further, described balance arm, cutting edge make batcher and counterweight constitute a balanced system, and by LOAD CELLS, the directly variation of powder quality in the scale feeder after the data processing, calculates the real-time feeding coal of batcher.
Compared with prior art, the invention has the beneficial effects as follows: adopt balancing method, the quality that LOAD CELLS is measured is the powder quality of removing after batcher is conducted oneself with dignity, can directly measure the powder net weight, can reduce the LOAD CELLS range greatly, improve the LOAD CELLS effective accuracy, accurately measure the feeding coal of the micro-batcher of " the tare weight amount is little ", can reduce the range of survey sensor, improve measuring accuracy, effectively solve the measurement difficult problem of micro-feed and the little batcher of tare weight amount.
Description of drawings
In order to be illustrated more clearly in technical scheme of the present invention, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is system construction drawing of the present invention.
Among the figure: 1. batcher, 2. counterweight, 3. balance arm, 4. cutting edge, 5. LOAD CELLS.
Embodiment
In order more to be expressly understood technical scheme of the present invention, the present invention is further described below in conjunction with accompanying drawing.
A kind of batcher feed measuring method of the present invention adopts equilibrium principle, sets up a balanced system, and directly the real-time quality of powder in the scale feeder by calculating the real-time change of powder quality, calculates the real-time feeding coal of batcher.Adopt balancing method, the quality that LOAD CELLS is measured is the powder quality of removing after batcher is conducted oneself with dignity, the net weight that just is commonly called as.For micro-batcher, the powder net weight is very little with respect to the batcher deadweight.Can directly measure the powder net weight, can reduce the LOAD CELLS range greatly, improve the LOAD CELLS effective accuracy, accurately measure the feeding coal of the micro-batcher of " the tare weight amount is little ".
A kind of batcher feeding system of the present invention, it comprises batcher 1, counterweight 2, balance arm 3, cutting edge 4, LOAD CELLS 5, and described balance arm 3 places on the cutting edge 4, and a side arranges batcher 1, opposite side arranges counterweight 2, and the lower end of batcher is provided with LOAD CELLS 5; Described balance arm 3, cutting edge 4 make batcher 1 and counterweight 2 constitute a balanced system, and by LOAD CELLS 5, the directly variation of powder quality in the scale feeder 1 after the data processing, calculates the real-time feeding coal of batcher.
The above only is preferred embodiments of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in the patent claim of the present invention.
