How to improve the counting accuracy of electronic grain counting machine?

Methods to improve the counting accuracy of electronic grain counting machines:

   1. Human factors:

⑴It is necessary to preheat for 3 to 10 minutes when starting up so that the electronic components and photoelectric scanning circuit are in a stable operating condition.

⑵The operators pay attention to the materials in the warehouse in real time and replenish the materials in time.

   2. Elements of the machine:

    ⑴Aiming at the problem that the feeding bin of the electronic grain counting machine is affected by the gravity of the material. You can consider dividing the silos into constant weight warehouses and non-constant weight warehouses. In this way, the influence of material gravity on the separation of materials in the vibrating plate can be effectively solved.

    ⑵ Regarding the problem that the material takes too long to fall from the memory baffle to the bottle, you should consider adding another level of memory baffle, which can solve the following problems. Firstly, the time when the material falls from the recall baffle to the bottle can be divided into two stages. The filling time of the bottle is shortened, and the first recall baffle is closed when the bottle is being loaded. The counter continues to work. In this way, two actions can be completed---the unloading and bottling of the previous bottle and the counting of the next bottle, and the production speed is improved. Secondly, it can solve the problem of electrostatic adsorption of materials.

    ⑶Methods to prevent static electricity①. You can install partitions or attach non-polar materials to the inner wall of the shot guard to prevent electronic transport. ②. Add grounded power cords and equipment connections to the shot guard. Effectively discharge static electricity and then avoid static electricity.

    ⑷Adjust the position of the recall baffle and the falling guard so that the recall baffle can completely block the materials, and the falling guard can ensure that the medicine particles enter the packaging bottle smoothly.

    ⑸ When installing and adjusting the machine, the level of the vibrating plate is adjusted backwards so that the material cannot naturally slide into the detection channel when the vibrating plate stops vibrating, causing false counting.

  3. Elements of materials

  ⑴ Set appropriate vibration frequency for capsules, tablets and pills.

⑵ Periodically use a vacuum cleaner to remove dust from tablets and capsules.

  4.Media elements:

⑴Replace compressed air filters regularly to ensure air quality.

  5. Parameter setting:

The settings for the size of the silo gate, the vibration frequency of the three-stage vibrating plate, the product length and minimum parameters, the value of the expected number, the counting speed and the separation speed require the operator to repeatedly debug to achieve the best condition, which not only ensures the counting speed More ensures the accuracy of counting.

  6. Methods to improve cylinder sensitivity.

Strictly control the moisture content of compressed air. In particular, the operation of the air dryer must be kept stable. Strictly control non-cylinder-specific grease from entering execution components. When repairing and replacing actuating components, be sure to replace the original cylinder. If possible, it is best to replace the actuating components of all channels at once to ensure the consistency of the sensitivity of the actuating components. Reasonably adjust the machine parameters, prepare the counting and counting speed to achieve the best separation effect of the product, thereby improving the production speed and counting accuracy. When setting the separation speed, the separation speed should be set as close to or the same as the counting speed. According to experience, the separation speed should be 5-10% lower than the counting speed value.
