Description

Technical Field

[0001] The utility model relates to the technical field of filter rod preparation devices, in particular to a preparation device for a double tow mixed filter rod. Background Art

[0002] As a key auxiliary material of cigarettes, filter rods are an important carrier for reducing harm and tar and innovating functions of cigarettes. With the improvement of consumers' requirements for the smoking experience of cigarettes, higher requirements are put forward for cigarette filter rods. Soft filter rods, thermal collapse and too high pressure drop will all have an adverse impact on the smoking experience of cigarettes.

[0003] A single-component cellulose acetate filter rod is usually processed from a single specification of tow. The filter rod of a single specification of tow is limited by the characteristics of the tow, and the adjustment space for indicators such as the filtration efficiency, pressure drop and hardness of the filter rod is limited; with the production and research and development of tow manufacturers at home and abroad, the specifications of tobacco filter tow have been gradually enriched, expanding the selection range of filter tow; the double tow filter rod can give full play to the advantages of each specification of tow and provide more space for adjusting the technical indicators of the filter rod by using double opening equipment. However, after the traditional double opening equipment opens the double tow, the double tow cannot be mixed. For example, for a forming device for a filter rod without wrapping paper provided in Patent CN201821996211.5, the double tow is directly shaped and fixed into a filter rod after passing through the double opening equipment, which easily leads to uneven mixing of the double tow in the filter rod and affects the use effect of the filter rod.

The mixed wire mechanism 20 is arranged behind the double loosening mechanism 10 along the conveying direction and includes two sets of first looseners 21 and one set of mixing components 22. The two sets of first looseners 21 are respectively used to introduce the first tow 2 and the second tow 3 and loosen them. The mixing component 22 is arranged behind the two sets of first looseners 21 along the conveying direction, and the mixing component 22 is used to mix the first tow 2 and the second tow 3.

[0024] The first opening component 11 and the second opening component 12 of the double-opening mechanism 10 are respectively used to open the first tow 2 and the second tow 3, which is convenient for the subsequent mixing of the first tow 2 and the second tow 3 in the mixing mechanism 20. Among them, in the mixing mechanism 20, two sets of first opening devices 21 can be used to further and fully open the first tow 2 and the second tow 3. Then, under the action of the mixing component 22, the first tow 2 and the second tow 3 are evenly mixed to form a filter rod, improving the use effect of the filter rod; and by setting the first opening component 11 and the second opening component 12 to open the first tow 2 and the second tow 3 respectively, the first tow 2 and the second tow 3 can be individually regulated, improving flexibility.

[0025] In an alternative embodiment of the present embodiment, preferably, the mixing mechanism 20 further includes a first output component 23 disposed behind the mixing component 22 along the conveying direction. The first output component 23 is used to output the mixed first tow 2 and second tow 3, and the mixed and formed filter rod is output through the first output component 23.

[0026] In an alternative embodiment of the present embodiment, preferably, both the first opening component 11 and the second opening component 12 include, along the conveying direction, a second opening device 13, an opening roller assembly 14, a third opening device 15, a plasticizer tank 16, and a second output component 17 arranged in sequence; the second opening device 13, the opening roller assembly 14, and the third opening device 15 can all open the first tow 2 or the second tow 3; the plasticizer tank 16 is used to apply a plasticizer, such as glyceride, to the first tow 2 or the second tow 3, which can increase the plasticity of the tow; the second output component 17 is used to output the first tow 2 or the second tow 3 to the corresponding first opening device 21.

[0027] Further preferably, the first opening device 21, the second opening device 13, and the third opening device 15 all include at least one set of air opening plates. Among them, the second opening device 13 may include two sets of air opening plates arranged in the conveying direction to fully open the tow. The first air opening plate is used to unfold the tow to prevent the tow from being twisted or folded, and the next air opening plate is used to unfold the tow and guide the tow into the first pre-tensioning roller 141; the third opening device 15 can open the tow to facilitate the application of the plasticizer.

[0028] Further preferably, each opening roller assembly 14 includes, along the conveying direction, a first pre-tensioning roller 141, a feeding roller 142, and a speed ratio roller 143 arranged in sequence; the first pre-tensioning roller 141 is rotatably arranged in pairs, and is used to adjust the tension of the tow while opening to maintain a constant tension of the tow; the feeding roller 142 and the speed ratio roller 143 are also rotatably arranged in pairs respectively, and 143 is used to reduce the degree of tow curling.

[0029] Further preferably, both the first output member 23 and the second output member 17 are provided as output rollers, which are rotatably arranged in pairs for outputting the tow.

[0031] When adjusting the draw resistance of the filter rod, the feeding amount of the first tow 2 or the second tow 3 can be adjusted by adjusting the rotational speed of the corresponding independent output roller; since the glyceride is applied independently, the application amount of the glyceride can be adjusted separately according to the tow specification and the feeding amount, and the application process is the same as that of the normal acetate fiber filter rod, which can make the application of the glyceride more uniform; the opening parameters of the tow, such as the ratio of the output roller, the tow roller 142 and the speed ratio roller 143, can also be adjusted separately according to the characteristics of the first tow 2 or the second tow 3 to ensure good opening of each tow.

[0032] Further preferably, the preparation device 1 of the double-tow mixed filter rod provided in this embodiment further includes two storage members 30 for storing the first tow 2 and the second tow 3 respectively, and the two storage members 30 are arranged in front of the double-opening mechanism 10 along the conveying direction; by providing the two storage members 30, it is convenient to store the first tow 2 and the second tow 3.
