The capsule counting machine is a machine suitable for counting pharmaceuticals, foods and other industries in the pharmaceutical, hospital, food and other industries. The machine is small in size, light in weight, accurate in counting and easy to operate. The contact surface of the counting items is made of stainless steel, which is an ideal special equipment for counting the bottled, bagged and canned products of various related industries. According to the industry, with the upgrading of the concept of consumption, the counting accuracy of capsule counting machines has been paid more and more attention by manufacturers. Below, the author briefly talks about several factors that affect the accuracy of the capsule counting machine.

Human Factors

The operator did not preheat the machine before starting the machine as required by the operating procedures. Or during the operation of the machine, the operator does not replenish the material in the silo in time, affecting the separation state of the material on the oscillating plate, which will result in inaccurate product counting.

Machine factor

For example, the design of the silo does not take into account the change of gravity, which will affect the fluidity and material sorting of the material in the oscillating plate; the gap between the memory baffle and the falling shroud is too large, and the material falls too long. The material rotates in the falling granule and cannot fall into the bottle in time, resulting in a number of inaccuracies; the capsule granule granule is made of plexiglass material, and the material is freely falling from the detection channel in the hood. High-speed rotary friction generates static electricity, or some Chinese medicine components also generate static electricity during the friction process. The effective amount of the material being adsorbed on the falling particle shield to fall into the bottle is reduced, and several grains are not allowed.

In addition, when the adjustment machine is installed, the horizontal adjustment of the oscillating plate is tilted forward, so that the material naturally slides down into the detection channel when the oscillating plate is stopped, which may also cause miscounting.

Material factor

The three-stage oscillating plates for producing capsules, tablets, and pills are set to have completely different oscillation frequencies. Or when the tablets and capsules are produced, due to the dust contained in the materials, the dust accumulation in the detection channel blocks the infrared rays, so that the counting circuit cannot work normally.


The quality of the compressed air can affect the accuracy of the count. The compressed air with large water content has a great influence on the sensitivity of the actuator cylinder. Once the sensitivity of the cylinder decreases, the accuracy of the counting cannot be guaranteed.

Parameter setting

The setting of the silo gate, the setting of the oscillation frequency of the three-stage oscillation plate, the setting of the product length and the minimum parameter, the setting of the expected value, the setting of the counting speed, and the setting of the separation speed all affect the capsule counting machine. accuracy.

Cylinder sensitivity drop

As the actuator of the capsule granulator, the speed of the reaction directly affects the accuracy of the counting. The reasons for the decrease in cylinder sensitivity are: moisture content in compressed air, non-cylinder-specific grease, impurities entering the cylinder, and seals of cylinders leaking and leaking.

In general, the accuracy of the capsule granulator will affect the production of the enterprise. Only the operators can check and pay more attention to the above aspects to ensure the stable operation of the equipment and ensure accurate counting of the products. In addition, the maintenance of the capsule granulator is also very necessary. At present, many customers report that which method of counting and several kinds of equipment is selected to play a decisive role in the production efficiency of medicines. It is reported that in order to solve this problem, many counting machine manufacturers are also actively researching and developing new types of capsule counting machine.
