Description

Technical Field

[0001] The invention belongs to the technical field of capsule machines, in particular to a multi-layer rubber box. Background Art

[0002] Nowadays, most health products are in capsule form, that is, liquid medicine is coated in rubber. The general production method is to spread the rubber on the surface of the mold, and then inject the liquid medicine into the holes of the mold and press it into capsules. The rubber used to coat the liquid medicine needs to be made with the help of the gelatin box on the capsule machine and the roller set at the bottom of the gelatin box. The gelatin box evenly spreads the paste colloid on the surface of the roller and rolls and cools into rubber with the roller to ensure the capsule is formed.

[0003] For example, publication number CN116919915B discloses a double-layer soft capsule, which includes an inner layer and an outer layer; wherein the raw materials for preparing the inner layer include: pullulan I, carrageenan oligosaccharide, carrageenan, starch, and distilled water; and the raw materials for preparing the outer layer include: pullulan II, KCl, carrageenan, glycerol, chitosan oligosaccharide, and distilled water. The soft capsule process of this technical solution is based on the outer layer applied to the inner rubber before forming to form a double-layer rubber, which is then pressed into a soft capsule by a soft capsule pill press, and finally the double-layer soft capsule product is obtained after finalizing, polishing, drying, and pill selection. However, the preparation process of the double-layer rubber requires spreading the inner layer of rubber liquid on the pill press to form a rubber, and then applying the outer layer of rubber liquid on the outer surface of the inner layer of rubber to form a double-layer rubber, and pressing the double-layer rubber and the contents into a soft capsule by a soft capsule pill press. The production process has low consistency and cannot reduce the production cost of the double-layer capsule.
