A kind of closed feeding precision control device and method

Abstract

The invention provides an apparatus for closed feeding precision control. The apparatus is provided with a feeding precision control device that comprises an attachment joint and a medical silicone flexible coupling connected to the attachment joint. Moderate feeding control cylinders, exact feeding control cylinders and shaking feeding cylinders, which are all connected to the control device, are disposed in order from top to bottom outside the medical silicone flexible coupling. Polyformaldehyde clamping plates are disposed at positions, facing the medical silicone flexible coupling, of the three groups of cylinders. The apparatus for closed feeding precision control is capable of realizing metered and proportioned delivery of a plurality of materials, and has the characteristics of accurate metering, high speed, no abrasion to materials, no powder falling, no layering, and high metering precision. Further, the apparatus has the advantages of high automation degree, simple operation, environmental protection and hygiene, accurate feeding, and high proportioning precision. With an automatic control center, a full view of the whole production process can be obtained to allow effective control on the operation procedure and efficient elimination of errors possibly caused by manual operation.

Description

Technical field [0001] The invention relates to the field of conveying, crushing, and packaging of powder materials, including drugs, food, chemicals, cosmetics, nuclear materials, etc., and specifically relates to the enclosed conveying, crushing, and automatic of materials such as drugs, food, chemicals, cosmetics, and nuclear materials. Sealed feeding accuracy control device and method for sub-packaging and automatic control. Background technique [0002] At present, the sub-packing types of powder materials are usually: manual sub-packing, feeding valve sub-packing, electromagnetic vibration feeding sub-packing type, etc. Manual sub-packing: 1. The accuracy is not guaranteed, 2. The efficiency is low, 3. Especially In the pharmaceutical industry, airtight and aseptic packaging cannot be achieved, and it cannot meet the requirements of the new version of GMP; Disadvantages of feeding valve packaging: 1. Frequent opening of the valve flap will cause the friction between the val...

Problems solved by technology

[0002] At present, the packaging types of powder materials are usually: manual packaging, feeding valve packaging, electromagnetic vibration feeding packaging, etc. Manual packaging: first, the accuracy is not guaranteed, second, the efficiency is low, third, especially In the pharmaceutical industry, it is impossible to achieve airtight and aseptic sub-packaging, which cannot meet the requirements of the new version of GMP; Disadvantages of sub-packaging of the feeding valve: 1. The frequent opening of the valve clack will cause debris to be generated by friction between the valve clack and the gasket, and pollute the material. 2. The seal between the valve disc and the gasket is not tight, which is easy to cause material leakage; electromagnetic vibration feeding sub-package: because the material moves forward in waves through electromagnetic vibration in the conveying pipe, the material is prone to stratification, so this type of sub-package Relatively high requirements on materials
