Perforated penetrable stirring paddle of coating machine

Abstract

The invention discloses a perforated penetrable stirring paddle of a coating machine. Stirring paddle bodies are fixed on a coating machine pot body through screws, and no gap exists between the stirring paddles and the bottom of the pot body, so that the condition that clamping pieces or tablets penetrate through the bottom without being mixed by the stirring paddles can be avoided, and uniform mixing of the tablets is facilitated. The flow guide far end of the stirring paddles rises and is bent towards the flow guide direction, so that the stirring flow guide effect on the tablets is furtherenhanced, and the coating uniformity is improved. Holes are formed in the side vertical faces of the stirring paddles, part of the tablets flow out from the middle holes, the falling height is reduced, the tablet knocking phenomenon is improved, when the tablets at the upper parts of the stirring paddles are turned over and fall, the lower parts of the tablets are buffered, the falling height isreduced, besides, the tablets do not make contact with the wall of the metal pot, and the tablet knocking phenomenon can also be reduced. The stirring paddle structure, the mounting and fixing mode, the position and the angle are improved, good rolling and mixing of the tablets in the coating process are achieved, coating uniformity and completeness are guaranteed, energy consumption can be reduced, the edge knocking phenomenon is reduced, the rejection rate is reduced, and the coating efficiency is remarkably improved.

Description

technical field [0001] The invention relates to a coating machine stirring paddle, in particular to a perforated and traversable coating machine stirring paddle, which belongs to the fields of medicine and food equipment. Background technique [0002] The high-efficiency coating machine is the key equipment for the production of tablets, capsules, pills, soft capsules and other medicines or food. Many properties of medicines such as moisture-proof, taste-masking, enteric coating, slow and controlled release, etc. need to be completed by the coating machine. It is very important whether the coating machine can evenly coat the tablet drug, which directly affects the quality of the drug and the clinical treatment effect. In order to ensure the uniformity and integrity of the coating. Inside the pot of the coating machine, an internal member-stirring paddle is set to perform the functions of tablet tumbling and mixing. The design of the stirring paddle is directly related to t...

Patent 200920257731.9 discloses a baffle for a coating pot, which is parallel to the axis of the pot body and divides the coating pot into small areas. During coating, the material slides with the rotation of the pot and meets the baffle. It can form tumbling, but this kind of tumbling is inclined and does not form a regular waterfall flow, which will inevitably lead to uneven coating

[0003] Patent 201320588787.9 discloses a coating pan with tumbling baffles. The tumbling baffles mentioned only describe the length and height, and the height is twice the width, which is extremely unrealistic. What is even more unrealistic is that the cross section is Triangular, this design is impossible to achieve a truly ideal coating, because the surface of the coated product or intermediate material is very regular, so that better smoothness and integrity can be achieved through the coating. If this The tumbling baffle with a triangular interface will inevitably cause serious damage to the surface of the product to be coated during the coating process, and slag, scraping, and debris will appear. wear and tear
