Description

Technical Field

[0001] This utility model relates to the field of cigarette filter technology, specifically to a composite filter rod integrally molded from natural colored plant material. Background Technology

[0002] The appearance and structure of cigarette filters are crucial for improving cigarette quality and attracting consumer interest. With industry upgrading, cigarette filters are no longer limited to ordinary white; colored functional filters are more common in high-end cigarettes.

[0003] Currently, colored composite filter rods are hollow, irregularly shaped by combining colored cellulose acetate segments with ordinary cellulose acetate segments. The colored cellulose acetate segments are made by adding pigments during the spinning process to create colored cellulose acetate tows, or by online dyeing and molding. This involves adding a dye to a plasticizer to create a colored plasticizer, which is then sprayed onto the opened cellulose acetate diacetate tow of tobacco using a filter rod forming machine's plasticizer application system before entering the cigarette gun for molding. This process of color composite filter rod molding contaminates the molding equipment and affects the production of normal white filter rods. Therefore, there are very few manufacturers in the industry that can provide colored cellulose acetate filter rods, and the procurement cycle is long and the purchase price is high.

[0004] In addition, existing colored fiber tow filter rods are not easily degraded and cause environmental pollution. For example, patent CN105755575B discloses a method for preparing colored polylactic acid fiber tow and filter rod for cigarettes. Although the raw material is derived from starch, it still needs to be dyed with pigments. The dyes used in colored fiber tow generally do not meet food-grade safety standards. They are prone to collapse due to heat during inhalation, affecting the inhalation quality. Moreover, they can easily cause pollution to the molding equipment and have high production costs. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art and to provide a composite filter rod made of natural colored plants in one piece through a combination of color and structure, which is conducive to the molding of production equipment, has low cost, safety and high production efficiency.

[0006] The technical solution adopted by this utility model is as follows:

[0007] A composite filter rod made of natural colored plant material in one piece is characterized by comprising a hollow rod close to the lip end, wrapped in molding paper and arranged in sequence, a natural colored plant material rod wrapped with shaping paper on the outside, and a solid base rod close to the tobacco end; the natural colored plant material rod has a hollow structure inside.

[0008] Furthermore, a hollow hole is provided at the axial center of the hollow rod, and the hollow hole and the hollow structure are combined to form a flue gas channel.

[0009] Furthermore, the geometry of the hollow hole is different from that of the perforated structure.

[0010] Furthermore, the hollow hole has a star-shaped structure, the center of the natural colored plant material rod is solid, and a wheel-shaped hollow structure is arranged around the solid center to penetrate the natural colored plant material rod.

[0011] Furthermore, the hollow hole has a leaf-shaped structure, and the center of the natural colored plant material rod has a branch-shaped hollow structure.

[0012] Furthermore, the hollow hole is an annular structure, and the center of the natural colored plant material rod is provided with a snowflake-shaped hollow structure.

[0013] Furthermore, the hollow rod has a length of 5-15mm, the natural colored plant material rod has a length of 5-15mm, the solid base rod has a length of 5-15mm, and the circumference diameter of all rods is 6.5-7.5mm.

[0014] Furthermore, the natural colored plant material bar is made from natural colored plants.

[0015] Furthermore, the solid base rod is a cellulose acetate filter rod.

[0016] The beneficial effects of this utility model are:

[0017] This invention combines the geometric shape of hollow holes with the hollow structure of colored natural plant material rods to form a mixed smoke channel. Under the negative pressure of cigarette smoking, it can change the smoke flow path, causing it to rise in a curve and extending the airflow path length, so that the smoke and flavor components can be better mixed, further improving the smoking quality and increasing the smoking interest. It can be applied to high-end cigarettes with colored functional filter rods. The natural colored plant material rods are highly safe, biodegradable, and do not pollute the environment. The one-piece molding process is simple and has low production costs. Attached Figure Description
