Description

Technical Field

[0001] The present invention relates to the technical field of cigarette filtration, and specifically to a PLA film flavoring process and its application on filter paper tubes. Background Art

[0002] A filter paper tube is a tool specifically designed for smokers, which can reduce the smoke, tar, and suspended particles generated during combustion inhaled when smoking. The three main functions of a cigarette filter include direct interception, inertial compaction, and diffusion precipitation. With the development of technology, more and more filter paper tubes with flavors have emerged, which can increase the taste and enhance the satisfaction of smoking.

[0003] Currently, there are various flavors in the heat-not-burn cigarette products on the market, and the method of placing flavor tablets in the mesh base rod is used as a flavor supplement method to enhance the aroma of various flavors. This process requires the gel to be first coated on the non-woven fabric and then placed in the mesh base rod, which increases the complexity of the rod-making process, and the low production capacity leads to a high cost of the mesh base rod. In order to simplify the flavoring and rod-making process of the flavored mesh base rod and reduce the overall production cost of the mesh base rod, a PLA film flavoring process and its application on filter paper tubes are proposed. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a PLA film flavoring process and its application on filter paper tubes, which solves the problems of complex rod-making process and high cost when adding flavors to filter paper tubes at present.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A PLA film flavoring process includes the following specific operation steps: S1. Open the package of the PLA film, install it on the conveying roller, and unfold and convey the PLA film; S2. When conveying, the PLA film passes through a texturing device to form orderly arranged raised patterns on its surface; S3. The textured PLA film enters a coating device, and a mixture of gel and essence is evenly coated on the surface of the PLA film through a coating roller; S4. The PLA film coated with the mixture of gel and essence is dried on the surface of the PLA film through a drying device to form a PLA flavored film.

[0006] Preferably, the mixture of gel and essence is mixed by a stirrer, and the essence is one or more of fragrance-carrying activated carbon, fragrance-carrying particles, and fragrance-carrying essential oils.

[0007] Preferably, the raw materials of the essence include plant extracts, sweeteners, and quercetin.

[0008] Preferably, the raw materials of the essence are extracts of blueberries, mint, or oranges.

[0009] Preferably, the coating equipment in S3 includes a coating box, the mixture of gel and flavor is located inside the coating box, a constant temperature device and a timed stirring mechanism are provided inside the coating box, a coating roller is installed at the bottom of the coating box, and the coating roller is in contact with the mixture of gel and flavor.

[0010] An application of PLA film fragrance on filter paper tubes, wherein the prepared PLA fragrance film is rolled into shape by a rolling machine, and a forming paper is coated on the surface of the film to form a mesh base rod; The mesh base rod is sent into the cutting device and cut into sections to make filter paper tubes.

[0011] Preferably, the extension direction of the central axis of the filter paper tube is consistent with the direction of the raised lines pressed from the PLA film.

[0012] Preferably, the side of the PLA film coated with the mixture of gel and flavor does not contact the forming paper inwardly during rolling.

[0013] The present invention provides a PLA film fragrance imparting process and method, which has the following beneficial effects: 1. The present invention adopts PLA film to make filter paper tube. PLA film material has low adsorption and good cooling characteristics. After the gel fragrance is added to the PLA film body, the heat of the smoke during inhalation causes the gel to liquefy and release the fragrance, while keeping the PLA material from shrinking due to heat and not easily solidifying, thereby improving the good permeability of smoke and the full release of fragrance during the inhalation process of the filter paper tube, and greatly improving the satisfaction of inhalation; 2. The present invention adopts a process of coating the fragrance and gel on a PLA film to make a filter paper tube, which makes it easier to add fragrance to the filter paper tube and has a wide fragrance range. The fragrance wrapped in the gel is released evenly. Compared with the traditional fragrance adding method, the process is simple and the cost is reduced by 10%-20%. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is the overall process flow chart of the present invention; Figure 2 This is a diagram of the PLA fragrance film of the present invention. DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Embodiment 1:

[0017] likeFigure 1 and Figure 2 As shown in Figure 2 , an embodiment of the present invention provides a PLA film flavoring process, including the following specific operation steps: S1. Unpack the PLA film, install it on the conveying roller, and unwind and convey the PLA film; S2. When conveying, the PLA film passes through a embossing device to form regularly arranged raised patterns on its surface, so as to increase the adhesion area during subsequent flavoring. The embossing device is a commonly used embossing machine on the market. After the PLA film is hot-pressed by the embossing roller, regular patterns are formed under the action of extrusion pressure; S3. The embossed PLA film enters the coating device. In the coating box of the coating device, a mixture of gel and essence is installed, and the mixture is kept at a constant temperature through a constant temperature device inside the coating box. At the same time, a timing stirring mechanism is also set inside the coating box to stir the mixture of gel and essence inside regularly to avoid precipitation. The coating roller is installed at the bottom of the coating box and contacts the mixture of gel and essence. When the coating roller rotates, the mixture will adhere to the coating roller, so that the PLA film passing under the coating roller will be evenly coated with the mixture of gel and essence on its upper surface; S4. The PLA film coated with the mixture of gel and essence passes through a drying device. The drying device can be composed of a drying fan and a blowing head. When the PLA film coated with the mixture of gel and essence passes through the blowing head, the blowing head can dry the surface of the PLA film to form a PLA flavored film.

[0018] Among them, the mixture of gel and essence is mixed by a stirrer. The essence is one or more of carrier-activated carbon for fragrance, carrier particles for fragrance, and carrier essential oil, which is convenient for mixing with the gel. The raw materials of the essence include plant extracts, sweeteners, and quercetin. Among them, plant extracts can increase the natural aroma, sweeteners can assist in adding a sweet taste to the plant extracts to make the taste better, and quercetin has a strong antioxidant effect and can effectively scavenge free radicals in the body, thus significantly reducing the damage of oxidative stress to lung tissue.

[0019] The raw materials of the essence are extracts of blueberries, mint or oranges, and can be extracted by ultrasonic extraction method, which is convenient to use.

[0020] Example 2: As Figure 1 shown, an application of a PLA film flavoring on a filter paper tube. The prepared PLA flavored film is rolled into shape by a rolling machine, and while rolling, the PLA flavored film is cut, so that it is rolled into multiple rods. The diameter of each rod is 6-9 mm, which can be determined according to the actual cigarette manufacturing specifications, and forming paper is coated on its surface to form a web-based rod; The mesh base rod is sent into a cutting device and cut into sections, each section being about 120 mm in length, to form a filter paper tube.

[0021] The extension direction of the central axis of the filter paper tube is consistent with the direction of the raised patterns pressed from the PLA film to ensure smooth flow of smoke. The side of the PLA film coated with a mixture of gel and flavor does not contact the forming paper inward during rolling.

[0022] After the filter paper tube is formed, it can be boxed. The boxing operation can be performed by a boxing machine. The boxing machine is connected to the cutting equipment after forming. The filter paper tube cut into sections will enter the boxing machine, pass through the conveying mechanism, counter and conversion guide mechanism, and be loaded into the box, waiting for inspection. After the inspection is completed, it can be packed and put into storage.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
