Description

Technical Field

[0001] The utility model relates to the technical field of film making machines, in particular to a desktop film making machine. Background Art

[0002] Oral fast-dissolving film is an oral drug preparation. When taking the medicine, the film is placed on the surface of the tongue or under the tongue. Within 10 to 60 seconds, the entire film is completely absorbed by the capillaries or dissolved in saliva and swallowed. The medication process can be completed quickly without drinking water.

[0003] At present, the preparation of oral instant film is completed by oral instant film film making machine. After the pre-treated material liquid enters the film making machine, the film making station makes the material into a uniform film and coats it on the base film. The composite film station composites the upper film on the material, and then reels it after multiple drying processes to obtain a finished dry film. For example, a U-shaped film making machine shown in the patent document with patent application number CN202410071472.X has a unwinding station for conveying the base film on the frame, and a film making station for coating the material on the base film, a drying station, and a film making station are sequentially arranged along the conveying direction of the base film. The U-shaped film making machine has the following disadvantages when used in practice: 1. The winding station lacks a correction mechanism for the base film, which makes it easy for the end faces of the base film to be uneven when it is wound up, affecting the winding quality; 2. The winding station has only one winding roller. After the winding roller completes winding, it is necessary to stop the machine to remove the material roll on the winding roller, and then put the empty winding roller back before rewinding. It is impossible to achieve non-stop winding; 3. It is large in size and cannot be used in laboratories and other scenarios that require a small film making machine. Summary of the invention

[0032] In the actual production process, this desktop film making machine is suitable for laboratories, office areas and small production environments due to its small volume and compact structure.

[0033] Install the bottom film roll at the unwinding station, put the material liquid medicine into the film manufacturing station, install the upper film roll at the composite film unwinding station. After the bottom film is output from the unwinding station, it successively passes through the film manufacturing station, the drying station, the composite station, and the winding station. The film manufacturing station coats the material on the bottom film. The bottom film coated with the material enters the drying space through the opening of the upper cover. Under the combined action of the exhaust duct and the heating element, the material is dried to obtain the medicine film, and then is output from the opening on the other side of the upper cover, bypasses the composite roller. The upper film is output from the composite film unwinding station and also bypasses the composite roller and is pasted above the medicine film. During threading, the auxiliary pressure roller is separated from the composite roller. During production, the auxiliary pressure roller presses on the composite roller. The bottom film and the upper film are composite under the combined action of the composite roller and the auxiliary pressure roller. The composite bottom film bypasses the deviation rectifying roller and then winds around the winding roller for winding. The deviation rectifying roller can rectify the bottom film to ensure the end face of the wound roll is neat during winding. By manually adjusting the deviation rectifying part, the deviation rectifying roller swings left and right to adjust the position of the bottom film on the deviation rectifying roller. When one of the winding rollers reaches the preset capacity, the operator cuts the film and winds it onto another winding roller. Since the composite roller and the auxiliary pressure roller have a clamping effect on the film, the winding roller can be replaced without stopping the machine.
