Description

Technical Field

[0001] The invention belongs to the technical field of filter tip processing, and specifically relates to a filter rod gap flavoring mechanism. Background Art

[0002] Flavoring technology is a key element in cigarette product design and development. Traditionally, flavoring is mostly added to cut tobacco. Flavoring tiplets are made by adding flavoring thread to cigarette filters. Each filter tip incorporates a multifunctional flavoring thread that enhances flavor and moisture retention. This reduces the filter system's ability to retain moisture in the smoke, improving the filtration of harmful oily components in the smoke, enhancing the aroma, smoothing the mouthfeel, and improving the smoking experience. With the increasing demand for innovative cigarette products, traditional flavoring methods are showing certain technical limitations.

[0003] Tobacco flavoring: First, many flavoring ingredients will undergo pyrolysis and loss during the smoking process of cigarettes, resulting in a decrease in the flavoring effect. Secondly, since many side reactions will occur during the combustion and pyrolysis process of the flavoring ingredients, there are potential health risks.

[0004] Direct filter flavoring: Using specialized equipment, flavors and fragrances are applied directly to the filter tip, creating an invisible scent line or ribbon anywhere on the tip. Direct flavoring eliminates equipment contamination and eliminates the need to consider compatibility with plasticizers or solvents, making it an effective way to incorporate flavors into cigarette filters.

[0005] Filter rod and fragrance string carrier: Filter rod and fragrance string carrier uses a special device to wrap a fragrance-impregnated fragrance string within the filter rod tow during filter formation. The fragrance string is typically made of cotton or synthetic fiber. Since the fragrance string does not participate in combustion, the requirements for the polarity, viscosity, and temperature of the fragrance are relatively low. However, filter rod and fragrance string carriers use one or more cotton strings or fibers to absorb the fragrance, and the release area is limited to the surface of these strings, resulting in limited absorption and low aroma transfer efficiency. Furthermore, to maintain the fragrance string in the center of each filter cutout, a centering device must be developed, which increases the complexity of the operation and process.

[0006] Filter rod adsorbent flavoring: Filter rod adsorbent flavoring is a flavoring technology that reduces harmful substances in mainstream cigarette smoke while also adding aroma. Activated carbon or silica gel are commonly used as adsorbents. The adsorbent, loaded with flavorings, is placed in the filter. As the mainstream smoke passes through the filter, the flavors are released from the adsorbent. While the flavors are being released, the particulate matter in the mainstream smoke is reduced after passing through the adsorbent, achieving the desired flavoring and harm reduction effects. However, this flavoring method does not effectively resolve the technical conflict between maintaining long-term aroma and evenly releasing it during inhalation.

[0007] Popping beads: Popping beads utilize inert polymerized natural or synthetic polymers to encapsulate flavors and fragrances within a sealed capsule, creating a semipermeable or sealed popping bead. The popping bead is then inserted into a filter plug. The advantages of popping bead filters lie in their ability to achieve controlled release of encapsulated flavors and fragrances under certain conditions, effectively reducing the impact of environmental factors and the interaction between different flavoring components. They also offer cigarette consumers choice, allowing them to crush the bead and smoke with or without flavoring. The popping bead delivers a distinct aroma upon crushing, creating a distinct and memorable experience. The stability of the bead ensures minimal loss of aroma throughout the entire cigarette manufacturing process, from manufacturing to consumer purchase. The high flavor capacity of the popping bead allows it to encapsulate flavors and fragrances with low aroma retention and high volatility, expanding the variety of flavors that can be used in filter plugs. However, the method of adding fragrance through popping beads is expensive and difficult to use on a larger scale. At the same time, due to the production requirements of popping beads, there are also restrictions on the application of some flavor ingredients. Utility Model Content

[0029] Although the technical solution of this application involves a controller, the controller's control of the solenoid valve is merely conventional on / off control, without involving other complex controls. The control of the servo motor is also conventional on / off control.
