[0002] Depending on the type of cigarette, the design of the filter rod is different. As the flavoring technology of cigarettes continues to upgrade, cigarette filter rods generally have the need to add flavor. Hollow filter rods are also called hollow tube filter rods. They are generally made by gathering the acetate fiber bundles and cooperating with the core rod to form a hollow area. The whole is formed by thermal curing and cooled. The common way to add flavor to hollow filter rods is to add flavor to the acetate fiber bundles before gathering them, such as Figure 1 As shown, the flavor adding position is generally between the output roller 100 and the wire feeding nozzle of the thermosetting molding machine, and the flavor is sprayed directly on the acetate fiber bundle using the atomizing nozzle 400. This method has a large amount of flavor diffusion, which is easy to affect the workshop environment, and the flavor loss is large, which greatly increases the cost; and different flavors have different properties. The film materials in some flavors may adhere to the surface of the core rod, increasing the surface friction, resulting in the heated and sticky bundle cannot be smoothly demolded, affecting the molding and molding quality of the filter rod.

DETAILED DESCRIPTION

[0022] like Figure 2-Figure 6 As shown, the utility model provides an online flavoring device for a heat-cured filter rod, which includes a core rod 4 and a tee piece 1. The outer surface of the core rod 4 is used to form a hollow area of ​​the filter rod. The filter rod is specifically a hollow filter rod formed by heat curing. During the molding process of the filter rod, the outer surface of the core rod 4 contacts the acetate fiber bundle, and the core rod 4 is used to form a corresponding hollow area when the acetate fiber bundle is gathered. The interior of the core rod 4 is hollow and both ends are connected. The three-way piece 1 has an inlet end 11, an inlet end 12 and an outlet end 13. The inlet end 11, the inlet end 12 and the outlet end 13 are connected to each other. The inlet end 11 is used to introduce compressed air, and the inlet end 12 is used to introduce essence. The outlet end 13 is connected to one end of the core rod 4. The other end of the core rod 4 is connected to a spray rod 5. The spray rod 5 is specifically connected to one end of the core rod 4 facing the cooling zone 300 when in use. The axis of the spray rod 5 is located on the same straight line as the axis of the core rod 4. When applied to the thermal curing filter rod molding, the filter rod after thermal curing molding moves toward the cooling zone 300, and the core rod 4 is located inside the filter rod after thermal curing molding. Preferably, the outer diameter of the spray rod 5 is smaller than the outer diameter of the core rod 4 to avoid or reduce friction with the inside of the filter rod. In the utility model, the essence introduced along the inlet end 12 is sprayed out along the end of the spray rod 5 under the action of compressed air.

[0023] The utility model improves the core rod 4 in the hollow area of ​​the filter rod in the heat-curing filter rod forming equipment, so that the core rod 4 is changed into a hollow structure. The outer surface of the core rod 4 can still normally bear the function of the hollow area of ​​the filter rod. The hollow structure of the core rod 4 combined with the three-way piece 1 and the spray rod 5 can use compressed air to mix the flavor and add the flavor evenly to the inside of the filter rod under the action of compressed air, so as to achieve online flavoring, avoid the problem of the acetate fiber bundle and the surface of the core rod 4 sticking due to the ingredients or properties of the flavor, and make the addition of the flavor more uniform, which is also conducive to the retention of the flavor in the filter rod. The setting of the spray rod 5 can lengthen the delivery path of the flavor on the original length of the core rod 4, such as Figure 6 As shown, the position where the flavor is added can be moved beyond the heat curing molding area 200 to the cooling area 300. At this time, the filter rod has been formed, and the heat curing molding effect and molding efficiency of the filter rod are avoided to avoid the influence of the flavor composition and property problems on the filter rod, thereby ensuring the molding quality of the filter rod. Figure 1 The utility model uses a method of directly spraying fragrance to the acetate fiber bundle through the atomizing nozzle 400 before bundling to reduce the amount of addition by about 75%, greatly saving the amount of fragrance used, reducing the cost of fragrance addition, and can greatly reduce the diffusion of fragrance, thereby greatly improving the working environment of the workshop.

[0024] In the present invention, the inlet end 11 is connected to the air source device through the air supply pipe 2, and the air source device supplies compressed air into the inlet end 11. In one embodiment of the present invention, the flavor enters directly from the inlet end 2 12.

[0025] In another embodiment of the utility model, a flavor delivery tube 6 is further included, and the flavor delivery tube 6 is inserted into the core rod 4 and the spray rod 5 along the inlet end 12, and the outer diameter of the flavor delivery tube 6 is smaller than the inner diameter of the core rod 4 and the spray rod 5, and a channel 31 for compressed air to flow is formed between the inner wall of the core rod 4 and the inner wall of the spray rod 5 and the outer side of the flavor delivery tube 6. In this embodiment, the flavor is introduced through the flavor delivery tube 6 along the inlet end 12, and is transported toward the spray rod 5 through the flavor delivery tube 6. After flowing out from the end of the flavor delivery tube 6, it is sprayed into the inside of the filter rod under the action of the compressed air in the outer circumferential direction to add flavor. In this method, the path from the flavor flowing out of its delivery unit to the flavor added to the inside of the filter rod is shorter, and the addition of the flavor is more effective.

[0026] like Figure 5 As shown, the end of the flavor delivery pipe 6 is located inside the spray rod 5, and there is a distance between the end of the flavor delivery pipe 6 and the end of the spray rod 5. A mixing chamber for flavor and compressed air is formed inside the spray rod 5 in the area where the distance is located, so that the flavor and compressed air are mixed and then sprayed together along the end of the spray rod 5 into the inside of the filter rod, thereby ensuring the uniformity of flavoring.

[0027] The flavor delivery tube 6 is fixed to the inlet end 12 to maintain the position of the flavor delivery tube 6 so that it will not move due to the action of compressed air. The flavor delivery tube 6 has an outer diameter of 1.5-2 mm and an inner diameter of 0.5-1.2 mm. The flavor delivery tube 6 is connected to an external flavor supply device, which drives the flavor to be delivered along the flavor delivery tube 6 through a pump. The specifications and models of the pump are based on actual needs and can meet the flavor addition amount of 15-40 g / min.

[0028] In the present invention, it is preferred that the fragrance delivery tube 6 and the second inlet end 12 are interference fit, which ensures that the fragrance delivery tube 6 and the second inlet end 12 are fixed and the sealing between the fragrance delivery tube 6 and the second inlet end 12 is ensured. Specifically, the end of the fragrance delivery tube 6 away from the spray rod 5 is provided with an outer diameter increase area, which is penetrated in the second inlet end 12 and has an interference fit. On this basis, the stability between the fragrance delivery tube 6 and the second inlet end 12 can also be increased by additional fasteners.

[0029] The utility model further comprises a fixing seat 3, on which the core rod 4 is arranged to support the core rod 4. A channel 31 is arranged inside the fixing seat 3, and one end of the core rod 4 away from the spray rod 5 is threadedly connected to one end of the channel 31, and the other end of the channel 31 is connected to the outlet end 13. In thermosetting molding, the core rod 4 is generally threadedly connected to the fixing seat 3, and this arrangement can meet the original design requirements of the threaded connection, and can also utilize the channel 31 formed inside the fixing seat 3 for the compressed gas to pass through and for the fragrance delivery pipe 6 to pass through.

[0030] The other end of the channel 31 is specifically connected to the outlet end 13 through the air pipe 2. The length of the air pipe 2 is determined according to actual needs. This arrangement can make the arrangement position of the three-way piece 1 more flexible and not limited to the bottom of the fixing seat 3. The flavor delivery pipe 6 is specifically arranged along the inlet end 12 to penetrate the air pipe 2, the channel 31, the core rod 4 and the spray rod 5. The outer diameter of the flavor delivery pipe 6 is smaller than the inner diameter of the air pipe 2 and the channel 31. The inner wall of the air pipe 2 and the inner wall of the channel 31 and the outer side of the flavor delivery pipe 6 form a channel 31 for compressed air to flow, thereby ensuring the normal delivery of compressed air.

[0031] In the present invention, the fragrance delivery tube 6 is a hose, that is, it has a certain bending ability, and is more convenient to be arranged inside the air pipe 2, the channel 31, the core rod 4 and the spray rod 5. Since the fragrance delivery tube 6 is fixed to the inlet end 12, and under the action of compressed air, it can also ensure that the fragrance delivery tube 6 extends toward the end of the spray rod 5. Preferably, when the tee 1, the air pipe 2, and the channel 31 have corner areas such as bends, the corners should be greater than or equal to 90° to avoid excessive bending arc when the fragrance delivery tube 6 is built in, resulting in the inability to normally deliver the fragrance.

[0032] The utility model also provides a heat-curing filter rod forming device, which is provided with the heat-curing filter rod online fragrance adding device as described above. In the heat-curing filter rod forming device, Figure 6 As shown, the core rod 4 is arranged in the heat curing molding area 200, and the extended core rod passes through the heat curing molding area 200 and its end is located in the cooling area 300. By providing the above-mentioned heat curing filter rod online flavoring device, it is possible to use compressed air to mix the flavor and add the flavor evenly to the inside of the filter rod under the action of compressed air, thereby realizing online flavoring and avoiding the problem of the acetate fiber bundle adhering to the surface of the core rod 4 due to the flavor components or properties. The addition of the flavor is more uniform, which is also conducive to the retention of the flavor in the filter rod. The spray rod 5 moves the flavor adding position across the heat curing molding area 200 to the cooling area 300. At this time, the filter rod has been formed, and the requirements for flavoring are met, thereby avoiding the influence of the flavor components and properties on the heat curing molding effect and molding efficiency of the filter rod, thereby ensuring the molding quality of the filter rod. Compared with Figure 1 The utility model uses a method of directly spraying fragrance to the acetate fiber bundle through the atomizing nozzle 400 before bundling to reduce the amount of addition by about 75%, greatly saving the amount of fragrance used, reducing the cost of fragrance addition, and can greatly reduce the diffusion of fragrance, thereby greatly improving the working environment of the workshop.
