Capsule pulling device

Abstract

The invention provides a capsule pulling device which comprises a working bin used for containing capsules to be disassembled and an exhaust chamber. Air is pressed into the working bin through an air inlet. The exhaust chamber is arranged above the working bin, an exhaust port is formed in the exhaust chamber, a first cylinder is arranged at the end face, away from the working bin, of the exhaust chamber, an output shaft of the first cylinder can stretch into the working bin, and an exhaust valve plate is fixedly connected to the end, stretching into the working bin, of the output shaft. A bin cover which can be sealed with and matched with the working bin is fixedly arranged at the end face, close to the working bin, of the exhaust chamber in a sleeving mode, a through pressure releasing hole is formed in the position, corresponding to the exhaust valve plate, of the bin cover, and the exhaust valve plate can seal the pressure releasing hole. According to the capsule pulling device, automatic disassembly of capsules is achieved through air pressure difference, and the defects that medicine powder is contaminated and the efficiency is low in manual disassembly are overcome.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical equipment, and in particular relates to a capsule extraction device for dismantling capsules through pressure difference and recovering medicinal powder. Background technique [0002] During the manufacturing process of capsules, there are many processes to go through, and some unqualified capsules will inevitably be produced, and most of these unqualified capsules are caused by appearance defects or deviations in filling volume. The medicine powder in the capsule is a qualified product. In order to save costs and avoid waste of medicine powder, unqualified capsule products need to be disassembled for recycling of medicine powder. [0003] The traditional recovery methods of powder are mainly through manual dismantling and pulverization. Manual dismantling is slow, inefficient, and consumes a lot of manpower and time. The operator directly contacts the powder to cause cross-contamination a...

AI Technical Summary

Problems solved by technology

Manual dismantling is slow, inefficient, and consumes a lot of manpower and time. The operator directly contacts the powder to cause cross-contamination and does not meet the GMP (Good Manufacturing Practice) management regulations.

The pulverization method uses traditional mechanical extrusion equipment to forcefully squeeze the capsules that need to be dismantled, so the capsules will be mixed in the drug powder after being squeezed and broken, resulting in impurity of the drug powder and increasing the work of later separation. amount; and in the process of squeezing the capsule, the powder filled in the capsule shell will inevitably be squeezed, thus destroying the shape of the powder
