Powder return device for hard capsules

Abstract

---- The invention belongs to the field of powder returning equipment, and in particular relates to a powder returning device for hard capsules, comprising a feeding funnel, a longitudinal channel connected to the feeding funnel, a capsule channel through which several individual capsules pass, an oscillating device, a collecting tank, Capsule shell outlet, conveyor belt, the conveyor belt is provided with a concave cavity parallel to the conveying direction, and a capsule groove matching the capsule is provided in the concave cavity, and a cutting wheel is provided at the end of the conveyor belt. The rotation direction of the wheel is counterclockwise; the oscillating plane is equipped with sieve holes, and the capsules are transported by setting a conveyor belt, and a cutting wheel is set at the end of the conveyor belt. Compared with extrusion crushing, the capsule shell fragments produced by this method are regular and will only During the cutting process, a limited amount of powder is produced, the cutting speed is fast, and the powder return efficiency is high; by setting a sieve whose sieve holes gradually become smaller from top to bottom, the obtained powder is more pure and prevents the mixing of small capsule shells.

Description

Technical field [0001] The invention belongs to the field of powder returning equipment, and particularly relates to a hard capsule powder returning device. [0002] technical background [0003] In the manufacturing process of capsules, some unqualified capsules will be produced. The reason for these unqualified capsules is mostly the defect of the outer shell or the deviation of the powder content, but there is no problem with the powder inside the capsule. In order to reduce the waste of the medicine, Recycle the unqualified capsule products. Traditional medicinal material recycling mainly uses three methods: manual dismantling, crushing and equipment recycling. Manual dismantling has the disadvantages of slow dismantling speed, consuming a lot of manpower and time, direct contact with pharmaceutical materials, causing cross-contamination, and not complying with GMP management regulations. The conventional crushing method is to crush the capsule shell. Because the capsule shell...

Problems solved by technology

Manual dismantling has the disadvantages of slow dismantling speed, consuming a lot of manpower and time, cross-contamination caused by direct contact with medicinal materials, and does not meet the regulations of GMP management. The conventional crushing method is to crush the capsule shell. Since the capsule shell is relatively brittle, The capsule shell will be broken into many small pieces by extrusion, and the small block capsule shell will be mixed into the medicine and become impurities, which needs to be further purified, which is cumbersome. Due to insufficient vibration of the large capsule crushed shell, the medicine powder will remain in the Inside the capsule shell, causing waste to be divided
