Description

Technical Field

[0001] The utility model relates to the technical field of orally dissolving film packaging machines, in particular to a slitting machine. Background Art

[0002] Orally disintegrating films are the latest generation of oral medications. Each film is about the size and thickness of a standard postage stamp. When taking medication, the film is placed on or under the tongue. Within 10 to 60 seconds, the film completely dissolves in saliva, allowing for rapid ingestion without the need for water.

[0003] Most orally dissolving films are made by using a film making machine to dry the material into a film and then adhere it to a base film. When packaging, the base film and the material film are first cut into multiple strips, and then the material film is cut to equal lengths. Then, the material film and the base film are peeled off, and the material film is wrapped with a packaging film, and then the packaging film is cut into multiple strips. Finally, the packaging film is cut to equal lengths into pieces of finished products. When using the packaging film to wrap the material film, in the prior art, an upper and a lower packaging film are usually used to cover the material film at the same time. The utility model with patent number CN220431765U discloses a packaging film unwinding mechanism of an orally dissolving film packaging machine, including an unwinding frame, and a film unwinding mechanism is installed on the unwinding frame along the packaging film. The film loading and unwinding direction is provided with a loading assembly for placing the packaging film roll, a splicing platform for splicing the two rolls head to tail, a packaging film slitting assembly for dividing the packaging film into two, an upper guide assembly for pulling half of the packaging film upward, and a lower guide assembly for pulling the other half of the packaging film downward. The splicing platform is arranged above the loading assembly, the upper guide assembly is located at the upper end of the unwinding frame, and the lower guide assembly is located at the lower end of the unwinding frame. The packaging film unwinding mechanism has the following disadvantages during use: 1. When the packaging film unwinding mechanism is put into the production line, the patent document with the patent application number CN202310596568.3 is referred to. Figure 1It can be seen that the packaging film unwinding mechanism is independently placed in front of the whole machine frame. Such position distribution will affect the operator's operation of the whole machine; 2. The packaging film slitting component adopts fixed slitting, and the position of the cutter wheel cannot be adjusted. When the packaging film is offset during the transportation process, the width of the upper and lower packaging films after slitting is no longer consistent, affecting subsequent packaging; 3. The specific structure and use of the splicing platform can refer to the utility model patent document with patent application number CN202123177556.2. The splicing platform mainly uses two pressing rollers to press The film to be spliced ​​and the film that is about to be exhausted, this film pressing method is very inconvenient, and the film needs to be passed through the pressing roller and ensure that the pressing roller can press the film, which increases the difficulty of changing materials; 4. Use the loading assembly to place the packaging film unwinding shaft. The packaging film unwinding shaft needs to be passed through the loading rod first, and then the loading rod is lifted so that the two ends of the loading rod can be plugged into the connecting disk. However, this loading method is very inconvenient for workers. The loading rod with the packaging film unwinding shaft has a certain weight. It is very difficult to successfully connect the loading rod with the connecting disk by lifting such a loading rod, which increases the difficulty of loading and reduces the loading efficiency.
