Description
Technical Field
The invention belongs to the technical field of reconstituted tobacco production and processing, and particularly relates to a follow-up type reconstituted tobacco tape-casting forming device by a thick slurry method.
Background
The tobacco raw material particles, the added fiber particles, the adhesive, the smoke agent and other materials in the thick pulp reconstituted tobacco slurry can be uniformly distributed on the surface layer and the inner layer of the reconstituted tobacco during molding, so that the thick pulp reconstituted tobacco has high homogenization degree, good processing resistance, good heat conduction uniformity and good smoke delivery uniformity and is one of the main reasons for being used as a material for heating a tobacco section of a cigarette. Such as: the iQOS cigarette developed by Felmo tobacco company adopts orderly arranged thick pulp method to reproduce tobacco leaves.
At present, researchers have more researches on the aspects of processing technology, raw material formula and the like of the thick paste method reconstituted tobacco special for the cigarette without burning. However, in addition to factors such as processing technology and raw material formula, the uniformity of the thickness of the reconstituted tobacco also has an important influence on the suction resistance and weight of the cigarettes. In the prior art, after the reconstituted tobacco is prepared, the thickness of the reconstituted tobacco in the next batch is adjusted by adjusting the gap between a thickness adjusting roller or a scraper and a steel belt, and no method is provided for adjusting the thickness of a reconstituted tobacco serous membrane in real time in the reconstituted tobacco preparation process. Such as: ZL201921935546.0 discloses a forming and drying system for reconstituted tobacco leaves by a thick paste method special for cigarettes without being heated and combusted, the invention patent discloses a forming and drying system for reconstituted tobacco leaves by a thick paste method special for cigarettes without being heated and combusted, wherein thick paste is subjected to tape casting forming through a tape casting box, sheets of the reconstituted tobacco leaves by the thick paste method are dried, thickness after stripping is subjected to fine adjustment through a thickness adjusting roller, the tape casting system is not developed in a targeted manner, and the thickness of the reconstituted tobacco leaves in the preparation process cannot be adjusted. ZL201921935579.5 discloses a forming system for preparing reconstituted tobacco sheets by a tape casting method, and the invention patent discloses a method for adjusting the thickness of reconstituted tobacco sheets by a thick liquid method by adjusting a gap between a knife gate and a steel belt. Patent CN106998784A of Felmo tobacco corporation in China discloses a casting device for casting a web for producing homogenized tobacco materials, which is provided with a removing scraper for removing caked pulp films formed in pulp and then adjusting the gap between the scraper and a steel belt so as to realize the method for accurately adjusting the thickness of reconstituted tobacco leaves by a thick pulp method.
In summary, the head box in the prior art is fixed on the frame, and the thickness of the reconstituted tobacco is adjusted by adjusting the gap between the scraper and the steel belt, however, in the tape casting process of the reconstituted tobacco by the thick slurry method, the thickness fluctuation of the reconstituted tobacco in the preparation process is large due to the thickness deviation of the formed steel belt and the circumferential runout of the hub, so that the cigarette filling degree is not uniform when the cigarette is rolled and heated, and the cigarette is large in suction resistance and weight change.
Therefore, the stability of the thickness of the thick paste method reconstituted tobacco is further improved, and the homogenization of the thick paste method reconstituted tobacco is ensured.
The present invention has been made to solve the above problems.
