It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0039] Example:

[0040] like Figure 1-4 As shown, this embodiment provides an ultra-long filter rod composite molding device, including a binary filter rod composite molding device consisting of a binary filter rod composite unit 2, a molding unit 3, a cutting unit 4 and a filter rod conveying device 5, a thin paper tube unit 1 is arranged on one side of the binary filter rod composite unit 2, the thin paper tube unit 1 conveys the lengthened filter rod through the filter rod conveying device 5 and the binary filter rod of the binary filter rod composite unit 2 is compositely molded by the molding unit 3, and then cut into an ultra-long filter rod by the cutting unit 4;

[0041] The thin paper tube unit 1 comprises a frame 11, a control panel 12, an electric control cabinet 13, an adjustment plate assembly 14, a feeding hub wheel assembly 15, an anti-pinch assembly 16, a guide plate 17, a rubbing rod assembly 18, and a manual feeding assembly 19;

[0042] The manual feeding assembly 19, the adjustment plate assembly 14, the feeding hub wheel assembly 15, the electric control cabinet 13, and the control panel 12 are arranged on the frame 11 from top to bottom. The anti-pinch assembly 16, the guide plate 17, and the rubbing rod assembly 18 are all arranged inside the adjustment plate assembly 14. The anti-pinch assembly 16 is driven to rotate by a motor drive device, and the rubbing rod assembly 18 is connected to the anti-pinch assembly 16 through a crank rocker mechanism to realize a swinging motion.

[0043] Specifically, Figure 1-2 As shown, after the extended filter rod enters the adjustment plate assembly 14 from the manual feeder 19 of the thin paper tube unit 1, it enters the hub wheel groove of the feeding hub wheel assembly 15 in an orderly manner under the arrangement of the rubbing rod assembly 18, the guide plate 17 and the anti-pinch assembly 16, follows the circumferential motion of the hub wheel to the lower end of the hub wheel, and then falls freely onto the suction belt 51 of the filter rod conveying device 5. The thin paper tube unit 1 controls the speed at which the filter rod falls onto the suction belt 51 by adjusting the knob of the control panel 12;

[0044] At the same time, the filter rods enter the silo from the feeding mechanism of the binary filter rod composite unit 2, and after being sorted, they enter the slitting unit 4 for slitting.

[0060] The working principle of the super-long filter rod composite forming equipment is as follows: the extended filter rod enters the adjustment plate assembly 14 from the thin paper tube unit 1 through the manual feeding assembly 19, and is then transported downward into the circumferential groove of the feeding hub wheel 151 assembly 15 under the stirring and guiding action of the rubbing rod assembly 18 and the guide plate, and follows the hub wheel 151 to rotate counterclockwise to the anti-pinch assembly 16, and the anti-pinch assembly 16 presses the filter rod in the groove of the hub wheel 151, so that there is only one filter rod in the circumferential groove of each cutting hub wheel 151, and the filter rod is adsorbed by the negative pressure in the groove of the hub wheel 151.

[0061] When the hub wheel 151 rotates to the lowest point, the extra-long filter rod falls onto the suction belt 51 of the filter rod conveying device 5 below.

[0062] At the same time, after the filter rod enters the adjusting plate assembly 14 from the manual loading assembly 19 of the binary filter rod composite unit 2, it is transported downward into the circumferential groove of the loading hub wheel 151 assembly 15 under the stirring of the rubbing rod assembly 18 and the guide plate, and follows the hub wheel 151 for circumferential movement to the top of the hub wheel 151, the anti-pinch assembly 16 presses the filter rod in the groove of the hub wheel 151 to ensure that there is only one filter rod in each groove of the hub wheel 151. After the filter rod follows the hub wheel 151 to rotate left and enter the tool magazine to be cut into specified rod segments, the filter rod continues to rotate downward in the groove of the hub wheel 151 following the hub wheel 151 to the lowest point of the hub wheel 151 and falls into the filter rod extraction mechanism, and then is transported downward into the cigarette removing device to change the running trajectory of the filter rod and then enters the suction belt 51 of the filter rod conveying device 5.

[0063] The two filter rods are conveyed downward on the suction belt 51 and enter the filter rod gap elimination sorting device, and then enter the forming unit 3 for paper wrapping, gluing, rolling and shaping, and then enter the slitting unit 4, and are cut into rod segments of specified lengths and then packed into boxes.
