Description

Technical Field

[0001] The utility model relates to the technical field of film making machines, in particular to an oven suitable for a U-shaped film making machine. Background Art

[0002] Oral film is a kind of 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 the saliva and swallowed. The medication process can be completed quickly without drinking water.

[0003] At present, the preparation of oral film is completed by an oral 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, and then rolls it into a finished dry film after multiple drying processes. The utility model with patent number CN218833173U discloses an oral film film making machine, which has a drying station, the drying station includes a first drying station and a second drying station arranged side by side, the drying station includes an upper oven that is flippable on a frame, a lower oven located below the upper oven and fixedly connected to the frame, a heater connected to the upper oven, and a fan connected to the heater, the lower end surface of the upper oven is provided with an air outlet panel, the upper end surface of the lower oven is provided with an exhaust panel opposite to the air outlet panel, and the exhaust panel is provided with a roller for conveying the base film.

The bottom film is passed through the lower oven, and the hot air is blown to the bottom film from the air outlet panel of the upper oven. Due to the lack of a structure to guide the hot air, there will be some wind loss when the hot air is blown to the bottom film, further reducing the drying efficiency and energy utilization; 3. The two drying stations are distributed side by side, which increases the length of the whole machine, occupies too large an area, and has low space utilization inside the equipment. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide an oven suitable for a U-shaped film making machine in view of the above-mentioned deficiencies in the prior art, which has high space utilization, small equipment footprint and high drying efficiency.
