An electronic grain counting machine with a forced dust suction device

Abstract

The invention relates to drug manufacturing equipments, in particular to an electronic grain counting machine with a forced dust absorption device. The electronic grain counting machine with the forced dust absorption device can solve the problems of the electronic grain counting machine that such solid preparations as tablet would generate dust in the process of oscillation grain counting, the dust would disturb the photoelectric grain counting and cause inaccurate grain counting frequently, or the electronic grain counting machine would give an alarm and stop working, and accordingly the production continuity, the production efficiency and the product quality are influenced.

[0004] The pharmaceutical oral solid preparation workshop uses an electronic counting machine to count and fill tablets. During production, the tablets are oscillated and separated by a multi-stage oscillating sieve plate. In this process, the friction between the tablets and the oscillating sieving A large amount of drug dust (tablets mainly refer to plain tablets, that is, the drug powder is directly pressed by a tablet press, and the outer surface of the tablet is not coated with sugar or film coating) appears in the friction between the tablets. Most of these dusts will adhere to the tablets and be carried Enter the electronic counting area, and fall off and fly when falling into the filling hopper, and attach to the photoelectric sensor head of the electronic counting machine, directly covering the photoelectric sensor head of the electronic counting machine, causing inaccurate counting or alarm shutdown and other effects Continuous production requires frequent manual cleaning of the drug dust to ensure the accuracy and reliability of the electronic counting, which leads to a reduction in production efficiency (one shift needs to be cleaned more than 5 times, each time takes 20 minutes), and the drug dust passes through the deposition process The filling bucket falls on the opening of the medicine bottle and inside the medicine bottle, which affects the sealing quality of the medicine bottle and the filling quality of the medicine

In order to solve this problem, most of the equipment manufacturers use slots on the vibrating screening plate, and then add dust suction devices at the lower part of the slot, the counting area and the filling hopper to catch dust. Complexity, relatively large equipment volume, and greatly increased manufacturing costs. In terms of practicability, nearly 50% of the drug dust cannot be effectively removed. The main reason is that the negative pressure of the dust collection device should not be too large, which will directly affect the tablet. The falling process affects the accuracy of electronic counting and filling

Therefore, this method is not a good solution for pharmaceutical dust.
