Filter stick with suspended inner core and preparation device and method thereof

Abstract

The invention discloses a filter stick with a suspended inner core and a preparation device and method thereof, belonging to the field of tobacco products. The preparation device comprises a first fiber bundle opening device, a second fiber bundle opening device, an inner core steam curing device and an outer core steam curing device, wherein the first fiber bundle opening device inputs first fibers into the inner core steam curing device to form an inner core; and the second fiber bundle opening device inputs second fibers into the outer core steam curing device to form an outer core. The preparation device is characterized by further comprising an inner core positioning device, wherein the inner core positioning device is provided with a hollow inner core pipe, the inner core enters the outer core steam curing device through the inner core pipe, and when the inner core pipe enters and exits from the outer core steam curing device in a reciprocating manner, a spaced hollow area is formed between the outer core and the inner core. With the filter stick provided by the invention, smoke is more uniform and softer, and cigarette quality is improved; the preparation device is simple in structure and low in cost; and the preparation method is simple and easy to implement, and the requirement for large-scale production can be met.

Description

technical field [0001] The invention belongs to the field of tobacco products, and in particular relates to an inner core suspended filter rod and a preparation device and method thereof. Background technique [0002] At present, with the continuous development of the tobacco industry and the increasing awareness of smokers, the requirements for harm reduction and coke reduction and the demand for personalized novelty are also getting higher and higher. As far as the filter rods used in cigarettes are concerned, the hollow filter rods have a very good novelty, and the coaxial core filter rods have the function of classifying and filtering smoke. However, the hollow filter rod itself does not have filtering characteristics, and generally needs to be used in combination. At the same time, the hollow filter rod generally has a "cavity effect", and the softness of the smoke is low. However, the inner core and the outer core of the coaxial core filter rod are usually tightly wra...

AI Technical Summary

Problems solved by technology

However, the hollow filter rod itself does not have filtering characteristics, and generally needs to be used in combination. At the same time, the hollow filter rod generally has a "cavity effect", and the softness of the smoke is low.

However, the inner core and outer core of the coaxial core filter rod are usually tightly packed, the mainstream smoke is not fully mixed, and there are inconsistencies in the sense of smoke

In terms of preparation methods, the hard inner core or special-shaped inner core of the coaxial core filter rod is mostly added in the form of small parts, which leads to high production costs and low efficiency.
