In the conventional assembly process of the initiating explosive device, the initiating explosive device is usually weighed manually by using an electronic balance, but the manual weighing method is long in time and high in danger. However, when weighing a medicine with poor dispersibility by using the automatic weighing method, the medicine is likely to be agglomerated, which is not favorable for precision control.

The patent application of the invention with the publication number of CN110736386A discloses a launching Y-scale sample loader, which comprises a rack, a support frame, a cartridge, a vibration material distribution mechanism and a cartridge, wherein the vibration material distribution mechanism and the cartridge are arranged in the rack, a material pouring mechanism, a material receiving box and a material blocking assembly are arranged on the cartridge, the cartridge is connected with the vibration material distribution mechanism through the material pouring mechanism, the material receiving box is fixedly arranged on the surface of one side of the cartridge, the material receiving box is communicated with the cartridge, the cartridge is positioned on the outer side of the vibration material distribution mechanism, the lower end of the cartridge is communicated and connected with a material pipe, and a weighing device is arranged on the support frame. Through vibration charging tray reason material, will granule shape propellant powder vibrations thick reinforced passage and thin reinforced passage through spiral slideway, guarantee the powder charge precision, thin reinforced passage closes when reaching the setting value, accomplishes the propellant powder and calls the dress to realized the accurate assembly of cartridge case propellant powder, add medicine with the essence including thick, replaced manual work, alleviate intensity of labour, improve production efficiency, avoid dangerous process manual work.

Above-mentioned transmission Y calls dress appearance machine adopts traditional vibration feed mechanism cooperation feed cylinder, material mechanism, weighing device etc. to realize the accurate assembly of cartridge case transmission medicine, and the work industry alleviates intensity of labour, improves production efficiency, avoids dangerous process manual work, but what this call dress appearance machine still adopted is traditional vibration depiler, does not consider that the medicament easily conglomerates when weighing to the less than good enough medicament of free-running nature, is unfavorable for the problem of accuracy control.

In view of this, the present application is specifically made.
