(1) Analysis of the reasons that affect the counting accuracy of the electronic particle counting machine:
1. Human factors: ①The operator did not preheat the machine before starting the machine according to the requirements of the operating procedures; ②The operator did not replenish the material in the silo in time during the operation of the machine, which directly affected the separation state of the material on the oscillating plate. Eventually lead to inaccurate product count.
2. Factors of electronic counting bottling machine:
(1) The design of the silo does not take into account that the change of gravity will affect the fluidity and sorting of the materials in the oscillating plate.
Because the more the material is, the higher the center of gravity of the material will be, which will increase the fluidity of the material, causing the overlapping materials to enter the detection channel before they can be separated, resulting in inaccurate number of particles.
With the reduction of the material, its center of gravity will decrease, which will reduce the fluidity of the material, which may cause the speed of counting particles to become slower.
(2) The drop between the memory baffle and the falling shield is too large, the falling time of the material is too long, and the material rotates in the falling shield and cannot fall into the packaging bottle in time, resulting in inaccurate number of grains.
(3) Since the granulation shield of the counting machine is made of plexiglass, when the material falls freely from the detection channel, static electricity is generated by high-speed rotation and friction in the shield. Another reason is that some traditional Chinese medicine ingredients are particularly prone to static electricity during the friction process.
Due to static electricity, the material is adsorbed on the droplet shield, which reduces the effective number of particles falling into the bottle, resulting in inaccurate number of particles.
⑷ If the memory baffle is not pushed out in place, it cannot completely block the material. When the memory baffle is opened, there are still materials passing through the memory baffle, causing the number of particles to be inaccurate.
⑸ The position of the droplet shield is incorrect, and the bottle mouth cannot be completely stuck, so that the material cannot all fall into the packaging bottle smoothly, resulting in inaccurate number of grains.
⑹ When installing and adjusting the machine, the horizontal adjustment of the oscillating plate is tilted forward, so that when the oscillating plate stops vibrating, the material will naturally slide into the detection channel and cause false counts.
