Example two:
referring to the attached drawings, a method for batching a powder raw material is applied to a batching device in the first embodiment, and comprises the following steps:
firstly, weighing density data of each powder medicine in a compact state, wherein the specific operation mode is as follows:
firstly, surveying meteorological data of a using place of a batching device to obtain an interval value of local temperature and humidity, then dividing the temperature into a plurality of small intervals by taking 5 ℃ as a gradient and 5% as a gradient of relative humidity, taking a middle value of each interval as a representative as an environmental parameter of a test, drawing a density table of the powder medicine by taking the temperature as an abscissa and taking the humidity as an ordinate, mutually matching the environmental parameters of the temperature and the humidity in a test room to measure a density value of the powder medicine in a compact state, filling the obtained density value into the density table, and storing information in the density table into a corresponding controller so as to be convenient for later-stage taking and use.
The compaction state in this step refers to a state that the powder medicine vibrates for 20-30s at a frequency of 50-200Hz, and based on the fact that the upper surface of the powder medicine does not sink any more after vibration, tests show that the correlation between the vibration compaction degree of the powder medicine and the vibration time is greater than the correlation between the vibration frequency and the vibration time, and therefore the vibration for 30s at 120Hz is preferred as the judgment standard for the compaction state of the powder medicine in this embodiment.
And step two, inputting the dosage of the powder medicine into the controller, automatically calculating the volume of the powder medicine by the controller according to the density of the corresponding compact state of the current powder medicine, converting the volume into height information of the piston cylinder 12, and controlling the corresponding stepping motor 21 to operate by the controller to adjust the height of the piston cylinder 12.
And step three, the controller controls the air cylinder 11 to enable the partition plate 10 to be drawn out of the dosing cylinder 7, the powder medicine flows into the dosing cylinder 7, after the dosing cylinder 7 is filled with the powder medicine, the vibrator 25 vibrates for 30 seconds at the frequency of 120Hz to obtain the powder medicine in a compact state, and after the powder medicine is in a stable state, the partition plate 10 is inserted into the dosing cylinder 7 again.
And step four, opening the discharge electromagnetic valve 14, introducing the powder medicines into the stirring tank 4, and uniformly stirring the powder medicines by the stirring tank 4 to finish the batching.
The working principle of the embodiment is as follows:
the embodiment shows the dosage of the powder medicine by volume, and measures the dosage of the powder medicine by measuring the volume of the powder medicine, so that the weighing error in the background technology can be effectively avoided, and the quality stability of the welding rod coating can be effectively improved. And the control is simpler, the automatic measuring can be realized, and the use convenience is high.
Because the powder medicine that stores in the storage cylinder 6 can reduce along with using, consequently the height of the powder medicine in the storage cylinder 6 is uncertain in the use, can cause the pressure of powder medicine in the storage cylinder 6 to the powder medicine in the batching section of thick bamboo 7 unstably like this, make the density of powder medicine in the batching section of thick bamboo 7 appear changing, such change can change the density of powder medicine to when getting the powder medicine according to the volume, still can have the error. Therefore, the concept of the density of the powder medicine in the compact state is provided in the application, the judgment standard is formulated according to the actual situation, the error caused by the density change of the powder medicine under different pressures is eliminated through the density in the compact state, and the accuracy of the quantity of the powder medicine can be further improved.
Simultaneously, the density of the powder medicine can be influenced by the ambient temperature and the ambient humidity, so that the density of different powder medicines in a compact state is measured according to different ambient temperatures and ambient humidity, a proper numerical value is selected according to actual use conditions, and the measuring error can be further eliminated.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, so: equivalent changes made according to the structure, shape and principle of the invention shall be covered by the protection scope of the invention.
