During the rotation, the arc-shaped slot 703 of the positioning adapter disk limits the filter rod segment 1 to prevent the filter rod segment 1 from detaching from the positioning chain 701.

[0031] Preferably, Figure 4As shown, the tooth root spacing between adjacent feed disc teeth 502 and adjacent segment combing disc teeth 602 is an equidistant arc length or an unequally spaced arc length. Further, in this embodiment, when the tooth root spacing between adjacent feed disc teeth 502 and adjacent segment combing disc teeth 602 is an equidistant arc length, the positioning device is suitable for the preparation of multi-component composite filter rods with the same length of filter rod segments 1. When the tooth root spacing between adjacent feed disc teeth 502 and adjacent segment combing disc teeth 602 is an unequally spaced arc length, the positioning device is suitable for the preparation of multi-component composite filter rods in which long filter rod segments 1 and short filter rod segments 1 are arranged in sequence. Further, the spacing between adjacent positioning chain teeth 702 matches the spacing between adjacent segment combing disc teeth 602. In this embodiment, the tooth root spacing between adjacent feed disc teeth 502 and the tooth root spacing between adjacent segment combing disc teeth 602 are customized according to the actual length of the filter rod segments 1.

[0032] Preferably, Figure 4 As shown, the positioning device also includes a positioning base (the positioning base is not shown) and a filter rod conveying platform 11.

A positioning chain 701 is arranged on the cavity positioning adapter plate 7. A plurality of positioning chain teeth 702 are arranged on the positioning chain 701. The filter rod segment 1 output from between the teeth 602 of the adjacent segment combing disk enters between the adjacent positioning chain teeth 702 and the filter rod segment arc-shaped slot outside the cavity positioning adapter plate 7 to limit the filter rod segment 1. The lower end of the positioning chain 701 is parallel to the filter rod conveying platform 11. In this embodiment, the adjacent positioning chain teeth 702 are used to receive the filter rod segment 1 transported in the segment combing disk 601.

[0033] Preferably, Figure 4 As shown, the feed adapter plate 5 and the segment combing adapter plate 6 are both axially penetrated with a plurality of hole slots 9, and corresponding connecting holes are opened on the main base 4. The hole slots 9 are aligned with the connecting holes and are fastened by fixing bolts 8. The connecting holes are aligned with different positions of the hole slots 9, so that the feed disk teeth 502 and the segment combing disk teeth 602, as well as the segment combing disk teeth 602 and the positioning chain teeth 702 are all meshed and aligned.

[0035] Preferably, in this embodiment, the width of the positioning chain teeth 702 is 5-25% smaller than the width of the filter rod cavity 2 of the multi-component composite filter rod. More preferably, the width of the positioning chain teeth 702 is 8-15% smaller than the filter rod cavity 2 of the multi-component composite filter rod. Figure 4 Dimension A( Figure 4 In this embodiment, the thickness of the positioning chain teeth 702 determines the width of the filter rod cavity 2, so the thickness of the positioning chain teeth 702 is designed according to the width of the filter rod cavity 2.

[0036] Preferably, in this embodiment, the height of the positioning chain teeth 702 is 5-20% smaller than the diameter of the filter rod segment 1 of the multi-component composite filter rod. More preferably, the width of the positioning chain teeth 702 is 10-15% smaller than the filter rod cavity 2 of the multi-component composite filter rod. Figure 4 Dimension B( Figure 4 In this embodiment, the height of the positioning chain teeth 702 is smaller than the diameter of the filter rod segment 1 so that when the filter rod segment 1 is on the filter rod conveying platform 11, the positioning chain teeth 702 will not contact the filter rod conveying platform 11.

[0037] Furthermore, in this embodiment, the positioning chain 701 will follow the filter rod segment 1 on the filter rod conveying platform 11 for a distance of 0.2-1m, generally 0.4-0.6m. Through the conveying over this distance, on the one hand, the position of the filter rod cavity 2 between adjacent filter rod segments 1 can be guaranteed, and on the other hand, the contact time between the filter rod segment 1 and the glue can be increased, thereby improving the bonding effect and preventing the subsequent filter rod segments 1 from being offset.

[0038] Preferably, Figure 1 , Figure 2 As shown, the multi-component composite filter stick includes a plurality of filter stick segments 1 and a forming paper 3, wherein the forming paper 3 wraps the plurality of filter stick segments 1, and a filter stick cavity 2 is formed between adjacent filter stick segments 1. In this embodiment, the filter stick cavity 2 can also be filled with a substance that changes the taste, such as a popping bead, to bring a better consumption experience to the user.

In this embodiment, the glue is applied intermittently, that is, glue is sprayed at the position where the filter rod segment 1 is located (i.e. Figure 3 The filter rod segment glue line 301 in the filter rod is not sprayed with glue at the position of the filter rod cavity 2 (i.e. Figure 3 The filter rod cavity in the filter rod has no glue line 302).

[0040] The multi-component composite filter rod cavity positioning device involved in the utility model has the following working principle:

[0041] First, the operator loosens the fixing bolts 8 on the feed adapter plate 5 and the segment combing adapter plate 6, and adjusts the positions of the hole slots 9 and the fixing bolts 8 so that the feed disk teeth 502 are aligned with the segment combing disk teeth 602, and the segment combing disk teeth 602 are aligned with the positioning chain teeth 702.

[0042] Then turn on the driving assembly, which drives the feed adapter plate 5, the segment combing adapter plate 6, or the cavity positioning adapter plate 7 to rotate, so that the feed adapter plate 5, the segment combing adapter plate 6, and the cavity positioning adapter plate 7 rotate synchronously through the transmission teeth. The filter rod segment 1 is conveyed to the feed adapter disk 5, the feed adapter disk 5 rotates, the filter rod segment 1 is stuck between the adjacent feed disk teeth 502, and because the feed adapter disk arc-shaped slot 503 limits the filter rod segment 1, the filter rod segment 1 will rotate with the feed disk 501; the filter rod segment 1 rotates to the segment combing disk 601, the adjacent segment combing disk teeth 602 receive the filter rod segment 1, the filter rod segment 1 rotates with the segment combing adapter disk 6, and the segment combing disk arc-shaped slot 603 limits the filter rod segment 1; the filter rod segment 1 rotates to the positioning chain 701, the adjacent positioning chain teeth 702 receive the filter rod segment 1, the filter rod segment 1 rotates with the positioning chain 701, and the positioning adapter disk arc-shaped slot 703 limits the filter rod segment 1; the filter rod segment 1 finally moves to the filter rod conveying platform 11 at the lower end of the positioning chain 701.

[0043] The filter rod conveying platform 11 is provided with a shaping paper 3, and a glue spray gun 10 is provided at the front end of the shaping paper 3, and the glue spray gun 10 sprays glue on the shaping paper 3 intermittently. The filter rod segment 1 is clamped between adjacent positioning chain teeth 702 and pressed on the shaping paper 3, and the shaping paper 3 is bonded to the filter rod segment 1. The positioning chain teeth 702 are pressed on the filter rod segment 1 and move together with the filter rod conveying platform 11 for a distance, so as to avoid the filter rod segment 1 from being offset. After the filter rod segment 1 is stable, the position of the filter rod cavity 2 between adjacent filter rod segments 1 is also stable without offset.

[0044] The utility model relates to a multi-component composite filter rod cavity positioning device, in which a positioning chain 701 is arranged on a cavity positioning adapter plate 7, and a plurality of positioning chain teeth 702 are provided on the positioning chain 701. When the positioning chain teeth 702 send the filter rod segment 1 to the shaping paper 3, the positioning chain 701 will also follow the filter rod segment 1 for a distance, on the one hand, stabilizing the position of the filter rod cavity 2 between adjacent filter rod segments 1, and on the other hand, increasing the contact time between the filter rod segment 1 and the shaping paper 3, thereby improving the bonding effect between the shaping paper 3 and the filter rod segment 1.

[0045] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
