Description

Technology Field

[0001] The present invention relates to a lyocell cigarette filter manufacturing device, and more specifically, to a device with improved productivity and ease of production. This relates to a lyocell cigarette filter manufacturing device. Background Technology

[0002] Generally, tobacco involves wrapping tobacco leaves or other materials in cigarette paper and inhaling the tobacco smoke produced by burning the cigarette paper and the tobacco. A filter is provided in the mouthpiece to filter out harmful components of the smoke and improve the flavor of the smoke.

[0003] Currently, most commercially available filters are manufactured based on cellulose acetate fibers, and these cellulose acetate-based filters are microplastics produced by reacting cellulose extracted from plants, such as wood and cottonseed, with an acetic acid solution. At this time, the cellulose acetate filters require a decomposition period of at least three years depending on environmental conditions. Consequently, toxic substances adsorbed within the discarded filters or within the filters are difficult to decompose by microorganisms, causing various environmental problems.

[0004] Accordingly, various biodegradable fibers are being developed to replace cellulose acetate fibers, but they have not yet reached commercialization because it is difficult to maintain filtration performance against harmful components of smoke and flavor when manufactured into filters.

[0005] Conventionally, research has been conducted on various eco-friendly and biodegradable cigarette filters to replace the aforementioned cellulose acetate. In particular, the production of cigarette filters using lyocell, a synthetic fiber derived from the natural resource cellulose, is being actively pursued.

[0006] However, since the aforementioned lyocell fibers are formed in the form of non-woven fabric, the quality of the filter may deteriorate and an imbalance in suction power may occur. Furthermore, due to the characteristics of the lyocell fiber structure, it is difficult to manufacture them into a circular shape, resulting in lower productivity compared to conventional cellulose acetate filters. Additionally, the lyocell fibers absorb moisture, such as saliva and humidity generated during smoking, causing the shape of the lyocell cigarette filter to deform over time, which may lead to a decline in product quality.

[0007] Therefore, considering these issues, there is an urgent need for research to improve the productivity and flexibility of lyocell cigarette filters used as a substitute for the aforementioned cellulose acetate filters. Prior art literature

Specific details for implementing the invention

[0020] Hereinafter, a lyocell cigarette filter manufacturing apparatus according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings. Here, it is preferable to understand the lyocell cigarette filter manufacturing apparatus as a manufacturing apparatus for producing a cigarette filter using lyocell tow made of lyocell material. In this case, the lyocell tow made of lyocell material is the same material as lyocell tow and is described and illustrated using the same reference numerals.

[0021] FIG. 1 is a schematic diagram showing a lyocell cigarette filter manufacturing apparatus according to an embodiment of the present invention, and FIG. 2 is a side view showing a lyocell cigarette filter manufacturing apparatus according to an embodiment of the present invention.

[0022] As shown in FIGS. 1 and 2, a lyocell cigarette filter manufacturing device (100) according to an embodiment of the present invention preferably includes a supply unit (10), a heating unit (20), a conveying unit (30), a guide roller unit (50), and a molding unit (60).

At this time, the lyocell cigarette filter manufacturing device (100) may be spaced apart from each other in correspondence with the conveying direction of the lyocell tow (1) for manufacturing the cigarette filter.

[0023] Here, according to one embodiment of the present invention, the supply unit (10) is preferably configured to supply the lyocell tow (1) on a surface made of lyocell material, and to withdraw and transport it at a preset withdrawal speed. At this time, the lyocell tow (1) may be configured to be wound onto a winding roll (10a) and stored. Additionally, the lyocell tow (1) may be arranged in a zigzag shape with spacing between them by a plurality of supply rollers (10b), and may be configured to guide the lyocell tow (1) supplied from the winding roll (10a).

[0024] Meanwhile, the heating unit (20) according to one embodiment of the present invention preferably includes a heating device (21) and a guide roller (22). At this time, the heating unit (20) is preferably positioned on one side of the supply unit (10), and is equipped with a heating device (21) that is heated to a preset temperature range to transfer heat for unwinding the lyocell tow (1) being drawn out and transported.

[0025] In addition, it is preferable to understand the above loosening treatment as a process of modifying the flexibility of the lyocell tow (1) through heating to prevent the phenomenon in which the lyocell tow (1) swells up due to weakening of the bonds between the lyocell fibers caused by liquids such as saliva, moisture, and heat.

[0026] At this time, it is preferable that the heating device (21) be configured to receive lyocell tow (1) from the supply unit (10) by means of the guide roller (22). That is, the guide roller (22) is configured between the supply unit (10) and the heating device (21), and it is preferable that the guide roller (22) be positioned at the top of the heating device (21) so that the lyocell tow (1) receives heat from the heating device (21).

[0027] Additionally, it is preferable that the guide roller (22) is provided to guide the transfer position so that the lyocell tow (1) is transferred to the transfer unit (30). At this time, it is preferable that the lyocell tow (1) is transferred by the guide roller (21) at a speed in the range of 100 to 250 RPM. Here, it is preferable that a first motor (not shown), which is a separate rotational means, is connected to the guide roller (21) to control the transfer speed of the lyocell tow (1) so that the rotational speed is controlled.

[0028] Additionally, it is preferable that the upper part of the heating device (21) be equipped with a heating plate that heats the surface to indirectly transfer heat to the lyocell tow (1).

[0034] In addition, as the above lyocell tow (1) is heated during production, the bonding of the fiber structure is weakened, thereby preventing deformation of the lyocell cigarette filter over time and improving production stability.

[0035] And, the temperature of the heating device (21) can be controlled according to the thickness, fiber distribution, and entry speed of the lyocell tow (1).
