Problems solved by technology

[0002] Cigarette filter rods, as a filter system for cigarette smoke, play an important role in improving the quality and safety of cigarette smoking. However, the current cigarette filter rods have a single form and simple functions, and the trend of cigarette homogeneity is becoming more and more serious. Therefore, new cigarette filter rods Excellent research and development has reached an unprecedented height in the industry
[0003] The application of granular materials in cigarette filter rods usually uses particles uniformly dispersed in acetate tow to prepare composite filter rods. On the one hand, the complex process leads to a sharp increase in cost, and on the other hand, the amount of particles used is extremely limited. Due to the "penetration effect" of particles Difficult to fully utilize
Another way of use is to concentrate the particles into the cavity with a fixed length between two cellulose acetate rods to form a ternary composite filter rod, which requires special equipment, and the amount of particles added cannot be precisely controlled and the cavity cannot be filled. The quality stability and hardness index of the rod are difficult to meet the requirements
At present, there are reports of filter rods obtained by integral molding of granular materials, such as application numbers CN2017105042856, CN2017105042926, etc., which relate to an environmentally friendly and degradable filter rod, which is formed by integral solidification of granular materials. It is a kind of filter rod with outstanding appearance and functional characteristics. Full particle filter sticks, but the smoke test results show that these filter sticks will lead to a substantial increase in harmful components such as phenol in the flue gas, reducing the usability of the filter sticks

[0071] The net conveyor belt 11 includes an upper conveyor belt and a lower conveyor belt connected as one, and the two ends of the mesh conveyor belt are horizontally supported on the guide wheel 1 and the driving wheel 12, and the upper conveyor belt is fed by the feeding device 3. mouth, and pass through the preforming device 4, the solidifying forming device 8, and the cooling / drying assembly 10 in sequence.

[0072] The bottom of the feeding device 3 is pro...

Embodiment 2

[0080] Such as Figure 7 As shown, Embodiment 2 of the equipment for preparing full-grain filter rods of the present invention is roughly the same as Embodiment 1, except that a cutting and finishing device 12 is provided at the output end of the cooling / drying assembly. The cutting and sorting device 12 cuts and sorts the formed unwrapped full particle filter rod 7 into boxes. The cutting and finishing device 12 can be a common cutting unit of an existing filter rod forming machine, and can also be modified accordingly according to actual needs.

Embodiment 3

[0082] Such as Figure 8 As shown, Embodiment 3 of the equipment for preparing full-grain filter rods of the present invention is roughly the same as Embodiment 1, except that the output end of the cooling / drying assembly 10 is connected to the wrapping device 13 and the cutting and finishing device 12 in sequence. In this embodiment, The paper wrapping device 13 is preferably an existing filter rod forming machine 15. The unwrapped full-grain filter rod 7 and the forming paper 151 are fed into the forming machine bong 152 in a certain way for forming, and then passed through the cutting and finishing device. 13 cutting and sorting into boxes to form a full particle filter rod 153 wrapped in paper.

Abstract

The invention discloses a harm-reducing full-particle filter stick and a preparation method and application thereof.The harm-reducing full-particle filter stick is integrally formed by a functional porous particle material through bonding and curing, and the preparation method comprises the steps that a binding agent adheres to the surface of the porous particle material, then a harm-reducing functional additive is modified, and the functional porous particle material is obtained; the functional porous particle material is formed by full-particle filter rod forming equipment. The harm-reducing full-particle filter rod is of an integrated rod-shaped structure formed by bonding and curing harm-reducing functional porous particle materials, has stable network-shaped porous morphological characteristics, and can provide a complex and smooth flue gas channel, flue gas can be in full contact with active ingredients loaded on the surfaces of the particles when passing through the filter rod, and therefore the filter rod can be used for filtering the active ingredients. The content of harmful ingredients such as phenol and crotonaldehyde in main stream smoke is greatly reduced.
