Problems solved by technology

Some products need to be made by uniform mixing of two or more component materials. Different materials need a certain period of time to cross-link and solidify. This kind of material is difficult to be blown into film; and when roller calendering is used, due to insufficient roller pressing time, resulting in Insufficient curing will lead to changes in film thickness due to material springback; on the one hand, molding technology is difficult to achieve continuous production, on the other hand, when producing large-area films, it is necessary to manufacture corresponding large precision molds, which is very costly
[0004] It can be seen that the existing technology is difficult to meet the pharmaceutical industry's demand for large-area thin film precision molding of viscoelastic materials, and it is also unable to meet the requirements of continuous production and consistency of drugs

Abstract

The invention provides precise forming equipment and method for a large-area viscoelastic material film. The film forming equipment comprises a rack, a mixing extrusion device, a movable bed, a cushion block, a pressing plate, a rolling device and a control system. A thin film material is extruded onto the movable bed, the rolling device is controlled to uniformly distribute and pre-press the thin film material, and the pressing plate is controlled to move to the cushion block to uniformly press the thin film material to a preset thickness. According to the thin film forming equipment, the thin film forming equipment control method and the thin film forming method, the requirement for precise forming of a large-area viscous-elastic material thin film in the pharmaceutical industry can be met, the thin film can be rapidly and evenly formed, continuous production can be achieved on the premise that the thickness precision of the thin film is guaranteed, the labor intensity of operators is reduced, and the production efficiency is effectively improved.

Description

technical field [0001] The present application relates to the technical field of medicinal film processing, in particular to a medicinal film forming equipment, a forming equipment control method and a medicinal film forming method. Background technique [0002] In the pharmaceutical industry, it is necessary to manufacture some films made of viscoelastic materials, and there are high requirements for the consistency of the thickness of such films. In addition, the pharmaceutical industry implements a continuous production process, which requires the elimination of mold batches (batches). difference. [0003] Existing film production mostly uses processes such as film blowing, calendering or molding. Some products need to be made by uniform mixing of two or more component materials. Different materials need a certain period of time to cross-link and solidify. This kind of material is difficult to be blown into film; and when roller calendering is used, due to insufficient r...
