Sealing stock bin

Abstract

The invention discloses a sealing stock bin, and relates to the technical field of coating gravure printing. The sealing stock bin comprises a stock bin body with a coating opening in the top and an anilox roller with the two ends rotationally connected with the stock bin body, wherein one side of the anilox roller penetrates the coating opening to extend out of the stock bin body; a scraper bladeconnected with the anilox roller is arranged on one side of the coating opening, and a teflon sealing plate connected with the anilox roller is arranged on the other side of the coating opening; andthe scraper blade, the anilox roller and the teflon sealing plate jointly seal the coating opening. The sealing stock bin is suitable for being used for low-boiling-point solvents, the low-boiling-point solvents such as dichloromethane can be used in the coating industry, the production safety is improved, and the production cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of coating gravure printing, in particular to a sealed feed bin. Background technique [0002] At present, the coating industry and the gravure printing industry use open hoppers. If such a hopper is used in coating and printing, if a solvent with a low boiling point is used, it will cause a large amount of volatilization of the solvent, which will cause a great impact on the environment of the workshop. The same external impurities are also easy to enter the silo, resulting in impurities on the coated or gravure-printed products. For some products with high requirements, the reject rate is high. In addition, the silo does not have automatic feeding. The function also requires manual on-duty and manual feeding. The operation is cumbersome, and it is easy to cause the material to be untimely, and the middle part of the film cannot be effectively coated, which affects the production effect of the product.

[0002] At present, the coating industry and the gravure printing industry use open hoppers. If such a hopper is used in coating and printing, if a solvent with a low boiling point is used, it will cause a large amount of volatilization of the solvent, which will cause a great impact on the environment of the workshop. The same external impurities are also easy to enter the silo, resulting in impurities on the coated or gravure-printed products. For some products with high requirements, the reject rate is high. In addition, the silo does not have automatic feeding. It also requires manual on-duty and manual feeding. The operation is more troublesome, and it is prone to untimely feeding. The middle part of the film cannot be effectively coated, which affects the production effect of the product. At the same time, it is easy to produce unqualified products and increase production costs.
