Abstract
The utility model relates to a constant feeder technical field, specific powder material constant feeder's automatic calibration system that says so, including the frame of weighing, weighing sensor is all installed in weighing frame upper end four corners, the landing leg is installed to the weighing sensor top, four groups the common fixedly connected with belt scale body in landing leg upper end, the hopper of weighing is installed on belt scale body upper end right side. The utility model discloses after pneumatic push-pull valve closed, structure itself is detached to the weight that weighing sensor recorded: after the weights of the supporting legs, the belt scale body and the weighing hopper, the weight of the powder material in the weighing hopper and the weight of the powder material on the belt scale body are determined as a standard quantity, the weight of the powder material in the weighing hopper measured by the weighing sensor and the weight of the powder material on the belt scale body are accumulated and then compared with the standard quantity, and a new calibration coefficient can be obtained.
Description
Technical Field
The utility model relates to a constant feeder technical field specifically is an automatic calibration system of powder material constant feeder.
Background
All constant feeders must be calibrated after the object is calibrated, and accurate measurement can be carried out. And the measurement precision cannot be influenced until the accumulated quantity of the real object calibration reaches more than 2% of the maximum conveying quantity of the equipment. Thus, the object calibration is time-consuming and labor-consuming, and is a relatively troublesome work. Moreover, the quantitative feeder is a dynamic device which continuously runs for 24 hours, and the accurate measurement of the quantitative feeder can be ensured only by frequently correcting a calibration coefficient.
Therefore, an automatic calibration system of the powder material constant feeder is provided.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an automatic calibration system of powder material constant feeder to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an automatic calibration system of powder material constant feeder, includes the frame of weighing, weighing sensor is all installed in weighing frame upper end four corners, the landing leg is installed to the weighing sensor top, four groups the common fixedly connected with belt scale body in landing leg upper end, the hopper of weighing is installed on belt scale body upper end right side, the hopper upper end of weighing communicates in feed bin lower extreme exit through the connecting pipe, pneumatic push-pull valve is installed with the junction of connecting pipe to the feed bin lower extreme.
As a further optimization of the technical scheme, the connecting pipe is a silica gel hose or a rubber hose.
As a further optimization of the technical scheme, the length of the belt scale body 4 is not more than 2700 mm.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses pneumatic push-pull valve is opened, and in the powder material in the feed bin entered into the hopper of weighing, then reachd the belt scale body on, the transport of weighing to the powder material, after pneumatic push-pull valve closed, the weight detach structure itself that weighing sensor recorded: after the weights of the supporting legs, the belt scale body and the weighing hopper, the weight of the powder material in the weighing hopper and the weight of the powder material on the belt scale body are determined as a standard quantity, the weight of the powder material in the weighing hopper measured by the weighing sensor and the weight of the powder material on the belt scale body are accumulated and then compared with the standard quantity, and a new calibration coefficient can be obtained. The calibration process can be carried out on line in production, so that the metering error can be corrected at any time, and the accuracy and the stability of the constant feeder are ensured.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1 weighing frame, 2 weighing sensor, 3 landing legs, 4 belt scale bodies, 5 weighing hoppers, 6 connecting pipes, 7 feed bins and 8 pneumatic gate valves.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: the utility model provides an automatic calibration system of powder material constant feeder, including weighing frame 1, weighing sensor 2 is all installed in weighing frame 1 upper end four corners, landing leg 3 is installed to weighing sensor 2 top, the common fixedly connected with belt scale body 4 in 3 upper ends of four group's landing legs, the belt scale body 4 is from taking the instrument of weighing for weigh the material on the belt scale body 4, when specifically setting up, the length of belt scale body 4 is no longer than 2700mm, the belt scale body 4 is shorter, the error is smaller, the accuracy of constant feeder is higher. The right side of the upper end of the belt scale body 4 is provided with a weighing hopper 5, and the weighing hopper 5 is provided with a weighing instrument and used for weighing materials in the weighing hopper 5. 5 upper ends of weighing hopper are passed through connecting pipe 6 and are linked together in 7 lower extreme exits of feed bin, and during concrete setting, connecting pipe 6 can choose for use to be silica gel hose or rubber hose for be the flexible coupling between 5 of weighing hopper and the feed bin 7, do not influence the error of weighing, improve quantitative feeder's accuracy and stability.
The pneumatic gate valve 8 is installed at the junction of the lower end of the bin 7 and the connecting pipe 6, and the flow of powder materials in the bin 7 entering the weighing hopper 5 is controlled through the pneumatic gate valve 8.
Specifically, during the use, pneumatic push-pull valve 8 is opened, and the powder material in the feed bin 7 enters into the hopper 5 of weighing, then arrives on the belt scale body 4, weighs the transport to the powder material, and after pneumatic push-pull valve 8 closed, the structure itself was got rid of to the weight that weighing sensor 2 recorded: after landing leg 3, the belt scale body 4 and the weight of the hopper 5 of weighing, for the weight of the powder material in the hopper 5 of weighing and the weight of the powder material on the belt scale body 4, the weight of the powder material in the hopper 5 of weighing that will weigh that weighing sensor 2 measured and the weight of the powder material on the belt scale body 4 are for the calibration volume, compare with the calibration volume after the weighing instrument measured value of the belt scale body 4 itself and the weighing instrument measured value of the hopper 5 of weighing itself accumulate, just can obtain new calibration coefficient. The calibration process can be carried out on line in production, so that the metering error can be corrected at any time, and the accuracy and the stability of the constant feeder are ensured.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
