AI Technical Summary

Technical Problem

The method of increasing the fragrance of filter paper tubes in the prior art is complex, and there is a lack of devices and processes for directly imparting fragrance on PLA membranes.

Method used

A PLA film incense device is designed, including a mixing box and an incense coating frame. The gel fragrance is heated by the heat conducting pipe in the agitating rod, and the stirring blades in the coating tank are rotated back and forth by using the linkage mechanism to achieve uniform coating of the gel fragrance.

Benefits of technology

The filter material production process is simplified, the cost is reduced, and the fluidity of the gel fragrance is improved through uniform heating and stirring, avoiding precipitation, and efficient fragrance delivery of the PLA film is achieved.

Abstract

The invention relates to the technical field of cigarette filtering, and provides a PLA film perfuming device and a perfuming technology.The perfuming device comprises a mixing box and a perfuming coating rack, a stirring rod is rotatably connected to the interior of the mixing box and used for mixing gel and essence, the interior of the stirring rod is hollow, a first heat conduction pipe is installed, and the first heat conduction pipe is provided with a second heat conduction pipe; and the top end and the bottom end of the first heat conduction pipe extend out of the mixing box and are connected with a hot liquid inlet pipe and a second heat conduction pipe through sealing rotating pieces correspondingly. According to the method, the PLA film is directly coated with the gel incense, so that the manufacturing steps of the filter material paper tube with fragrance are reduced, the production cost is reduced, the PLA aroma giving device integrates the manufacturing and coating of the gel incense, the gel incense can be uniformly heated and stirred by placing the first heat conduction pipe into the stirring rod, the fluidity is improved, and the production efficiency is improved. And meanwhile, through a linkage mode, stirring blades in the coating groove are driven to rotate back and forth when the perfuming electric coating roller rotates, so that precipitation is avoided, the conception is ingenious, and the innovativeness is high.
