Description

A tablet compression molding and coating device

technical field

The invention relates to the technical field of tablet production, in particular to a tablet compression molding and coating device.

Background technique

Pills are common items in life, and they are generally made by pressing tablets. The tableting method is a kind of dry molding, usually using a tableting machine to press the raw material powder into a tablet or ring. When pressing the tablet, first place the powder in the lower mold. The lower mold is generally a round hole or a square hole, and then the punch of the upper mold moves downward and presses the raw material powder into a sheet or ring together with the punch on the lower mold. , and finally the punch on the lower mold pushes the formed tablet out of the forming hole, so that a semi-finished tablet can be produced. However, in the feeding process in the forming hole of the lower die, artificial fillers are required, which not only increases the labor intensity of the workers, but also reduces the production efficiency of the tablets.

The produced semi-finished tablets are heavy in taste and dark in color and unattractive. Therefore, it is necessary to wrap the compressed tablets with a colored coating solution. The coating solution covers the smell of the semi-finished tablet and makes the prepared The tablet has color and has a more beautiful appearance. The traditional operation of coating semi-finished tablets with coating solution is to pour several semi-finished tablets into the tank containing the coating solution, then stir the coating solution, after a period of mixing, the coating solution wraps the semi-finished tablets, and finally take out the tablets , and put the tablets in a drying oven, and dry the tablets through the drying oven. After drying, the coating solution adheres tightly to the outside of the tablets to form a coating layer, and finally the finished tablets are obtained.

However, there are the following technical defects in the existing device for producing tablets: 1. The surface of the semi-finished tablet is smooth, and after the coating liquid coats the tablet, the coating layer formed is difficult to firmly adhere to the tablet due to the smooth surface of the tablet, that is, The coating layer is easy to fall off in the subsequent drying or transfer process, which greatly reduces the quality of the tablet and easily attracts complaints from consumers. 2. After stirring and mixing the coating solution and the semi-finished tablet in the tank, it is necessary to manually salvage the tablet from the tank, resulting in discontinuous production of the tablet and further reducing the production efficiency of the tablet. 3. From the stamping process of the tablet to the coating process of the tablet, manual transfer is required, and there is a defect of discontinuous production.

The Chinese patent application No. 201711087363.3 discloses a tablet coating equipment, including an operating room, a spray gun, an air spray device, a feeding device and a recovery device; the spray gun is located at the bottom of the operating room, and the air spray device includes a The sleeve outside the spray gun, the air injection channel arranged in the sleeve and the injection parts connected to the air injection channel; the injection parts are arranged obliquely; since the injection parts are arranged obliquely, and the inclination directions between the injection parts are set in the same direction . In the present invention, the injection part is set to be inclined, so that after the material is sprayed, it can rotate in the air to ensure uniform coating; and the material stays in the air for a long time, and the contact time with the packaging material is also longer, and the coating effect Good; and the uniformity of the coating makes the release rate of the tablet uniform in the gastric juice, effectively protecting people's intestinal health. Although this tablet coating equipment can wrap the coating liquid on the outside of the tablet, the surface of the formed coating layer and the main body of the tablet is smooth, and it is easy to cause the coating layer to be separated from the tablet body in the subsequent transportation or drying process. fall off.
