The sum of the time occupied by the rapid material supplementing section and the stable stirring section is the same as the time occupied by the uniform discharging section.
Through the arrangement, continuous output of liquid materials can be guaranteed, when the discharging rate of one of the first metering bin 2 and the second metering bin 3 reaches and is kept at the maximum, the other of the first metering bin 2 and the second metering bin 3 starts to supplement materials, the first metering bin 2 and the second metering bin 3 are matched with each other, and the materials are circularly reciprocated, so that the batching efficiency is improved.
Referring to fig. 1 and 2 in combination, in one embodiment of the present application, when the first metering bin 2 is in the discharge opening section and the second metering bin 3 is in the discharge closing section, the sum of the discharge speeds of the first metering bin 2 and the second metering bin 3 is equal to a preset speed; when the first metering bin 2 is in the discharging closing section and the second metering bin 3 is in the discharging opening section, the sum of the discharging speeds of the first metering bin 2 and the second metering bin 3 is equal to a preset speed.
Through the arrangement, the sum of the discharge amounts of the first metering bin 2 and the second metering bin 3 is kept unchanged all the time, and then the discharge amount is continuously and stably output.
From the above description, it can be seen that the above-described embodiments of the present application achieve the following technical effects: the first metering bin and the second metering bin are sequentially used for discharging, when the blanking device supplements the first metering bin, the first metering bin is inaccurate in metering due to the impact of liquid materials, the second metering bin is discharging at the moment, after the liquid materials in the first metering bin are stable, the number weighed by the first metering bin is the mass of the liquid materials in the first metering bin, after the first metering bin is stably weighed, the second metering bin stops discharging, and the first metering bin starts discharging; when unloader carries out the feed supplement to the second measurement storehouse, because the effect of liquid material impact leads to the measurement in second measurement storehouse inaccurate, and first measurement storehouse is being discharged this moment, and after the liquid material in the second measurement storehouse stabilized, the number of weighing with the second measurement storehouse is the quality of the liquid material in the second measurement storehouse, and after the second measurement storehouse stabilized weighing, first measurement storehouse stopped the ejection of compact, and the second measurement storehouse begins the ejection of compact. So reciprocating, realize continuous ejection of compact to avoided the impact force of liquid material to lead to weighing inaccurately, also avoided the feed supplement speed too slow problem that leads to batching inefficiency simultaneously.
