Bidirectional cold and hot matrix spreader for Chinese medicine plaster

Abstract

The present invention relates to spreader, and is especially one kind of bidirectional cold and hot matrix spreader for Chinese medicine plaster. The matrix spreader for Chinese medicine plaster includes one casing, one roller conveyer inside the casing, one low temperature stoving channel below the roller conveyer and with arranged air nozzles and air exhaust ports, one film covering unit in the outlet of the stoving channel, one cutting unit, one water emulsion sprayer in the inlet of the stoving channel to spray water medicine emulsion islands onto the isolating film, and one hot melt adhesive sprayer in the outlet of the stoving channel. Spraying both water emulsion and hot melt adhesive to the Chinese medicine plaster can preserve the low temperature medicine components in the plaster, ensure the water-resisting fast adhesion of the plaster, raise the medicinal effect and increase the use period.

Description

technical field [0001] The invention belongs to a coating machine, in particular to a two-way coating machine for hot and cold substrates of traditional Chinese medicine patches. Background technique [0002] Coating processing technology is to make the substrate have a certain function after coating a certain coating on a certain substrate, so as to produce products with various properties according to the needs. The early coating processing technology was manual coating, such as brush coating and scraper coating. With the needs of large-scale production, it is suitable for the needs of different industries, and coating equipment for various purposes has emerged as the times require. There are various varieties and structures. Such as spray coater, bar coater, knife coater, kiss coater, squeeze roll coater, reverse roll coater, transfer roll coater, etc.; , a single-function coating machine has been difficult to meet the requirements of new technology for coating equipmen...

AI Technical Summary

Problems solved by technology

However, as a traditional Chinese medicine patch, low-temperature preparation is required in the process of production. Since most drugs in traditional Chinese medicine have strong sublimation properties, they generally do not exceed 60°C during preparation and storage, while maintaining a certain degree of humidity. Water emulsion products Although it has the advantage of low temperature preparation, water latex products have poor water resistance, while hot melt adhesive products have strong water resistance and fastness. Large, unable to meet the preparation requirements of traditional Chinese medicine patches that not only retain the active ingredients of low-temperature drugs, but also ensure the water-resistant and fastness of the patch

[0004] Chinese patents [21] ZL02134809.X "multifunctional composite coating machine", [21] ZL96206700.8 "multifunctional combined coating machine" and the original [21] ZL95210946.8 "circling type drug film coating machine", etc. Although the patented scheme has greatly improved the coating machine, it still cannot meet the preparation requirements of the cold and hot matrix of traditional Chinese medicine patches
