The feeding mechanism for the multi-section composite cigarette filter sticks comprises a plurality of material loading devices 1 used for loading the cigarette filter sticks 5, a plurality of material conveying devices 2 used for conveying the cigarette filter sticks 5, and a material sorting device 3 used for sorting the cigarette filter sticks 5 in the material loading devices 1 to the material conveying devices 2; the material loading device 1 is used for loading cigarette filter sticks 5 in different sections, the material sorting device 3 is used for sorting the cigarette filter sticks 5 in different sections in the material loading device 1 to the corresponding material conveying devices 2 respectively, the material loading device further comprises a material clamping device 4 used for clamping the cigarette filter sticks 5 on the plurality of material conveying devices 2 to the compound platform respectively for compounding, and specific effects are shown in figure 1.

In the application, the cigarette filter sticks 5 of different sections are respectively loaded in the plurality of material loading devices 1, then the cigarette filter sticks 5 in each material loading device 1 are respectively sorted to the corresponding material conveying devices 2 through the material sorting devices 3, and finally the cigarette filter sticks 5 on each material conveying device 2 are clamped to the cigarette filter stick compound platform through the material clamping devices 4 for compounding, so that the feeding during the compounding of the multi-section cigarette filter sticks 5 is stably and reliably realized. Because the cigarette filter rods 5 need to be sequenced when the multiple sections of cigarette filter rods 5 are compounded, when the material sorting device 3 sorts the cigarette filter rods 5 in each material loading device 1, the cigarette filter rods 5 in the corresponding material loading devices 1 need to be sequentially sorted according to the compounding sequence of the cigarette filter rods 5, so that when the material clamping device 4 clamps the cigarette filter rods 5 on the material conveying device 2 to the cigarette filter rod compounding platform, the multiple sections of cigarette filter rods 5 are sequentially arranged according to the sequence, and the compounding of the cigarette filter rods 5 is facilitated.

The material loading device 1 comprises a tray type vibrating feeder 11 and a feeding track 12 which is arranged on one side of the tray type vibrating feeder 11 and used for sending out the cigarette filter sticks 5 in the tray type vibrating feeder 11, and the specific effect is shown in figure 2. The cigarette filter sticks 5 are poured into the disc type vibrating feeder 11, the cigarette filter sticks 5 in the disc type vibrating feeder 11 are sent out through a feeding rail 12 arranged on one side of the disc type vibrating feeder 11, and the material sorting device 3 sorts the cigarette filter sticks 5 on the feeding rail 12 to the material conveying device 2. The reason why the disk-type vibrating feeder 11 is adopted instead of the ordinary charging bucket is that the final cigarette filter sticks 5 are orderly arranged one by one when entering the feeding track 12, so that the sorting of the material sorting device 3 is facilitated. If a common charging bucket is adopted, when a large amount of cigarette filter sticks 5 are poured into the charging bucket, the cigarette filter sticks 5 are extruded mutually, so that the discharge port of the charging bucket is blocked, and the cigarette filter sticks 5 cannot smoothly reach the feeding track 12.

The material sorting device 3 is a parallel robot arranged between the material loading devices 1 and the material conveying devices 2, and the specific effect is shown in figure 1. The material sorting device 3 is a parallel robot and is arranged between the material loading devices 1 and the material conveying devices 2, and the cigarette filter sticks 5 in the material loading devices 1 are respectively sorted to the material conveying devices 2 through the parallel robot. In the actual production of the cigarette filter sticks 5, if the compounding of a plurality of sections of cigarette filter sticks 5 is required, the material loading devices 1 and the material conveying devices 2 with corresponding quantities are adopted, and meanwhile, the parallel robots with corresponding degrees of freedom are adopted to sort the cigarette filter sticks 5 on the material loading devices 1. For example, the following steps are carried out: if three-section cigarette filter sticks 5 are to be composited, three material loading devices 1 and three material conveying devices 2 are adopted, different three-section cigarette filter sticks 5 are respectively loaded into the three material loading devices 1, the three-degree-of-freedom parallel robots are used for respectively sorting the cigarette filter sticks 5 in the three material loading devices 1 to the corresponding three material conveying devices 2, and the material sorting device 3 can adopt a GSK C3-1100 parallel robot of Guangzhou King robot engineering technology Limited.

Since the inner peripheral surface of the conveyor belt 23 is provided with the serrations, when the drive wheel 21 rotates, the serrations of the inner peripheral surface of the conveyor belt 23 engage with the drive wheel 21, thereby rotating the conveyor belt 23. After the conveyor belt 23 starts to rotate, the sawteeth on the inner peripheral surface of the conveyor belt 23 are matched with the driven wheel 22 to drive the driven wheel 22 to rotate, so that the conveyor belt 23 rotates around the driving wheel 21 and the driven wheel 22, and further the cigarette filter sticks 5 placed on the conveyor belt 23 are driven to move forwards, and the situation that the placement of the cigarette filter sticks 5 which are sorted by the material sorting device 3 on the conveyor belt 23 is obstructed is avoided.

The material clamping device 4 comprises a clamping plate 41 for clamping the cigarette filter stick 5, a mounting seat 42 for fixing the clamping plate 41, and a sliding rail 43 for sliding the mounting seat 42 on, as shown in fig. 4. In the application, each mounting seat 42 is fixed with a clamping plate 41, and the two adjacent mounting seats 42 are close to each other on a sliding rail 43, so that the clamping plates 41 fixed on the two adjacent mounting seats 42 are respectively abutted against two ends of a cigarette filter stick 5, the clamping plates 41 clamp the cigarette filter sticks 5 on the material conveying device 2, and after clamping is completed, the mounting seats 42 move on the sliding rail 43, so that the cigarette filter sticks 5 clamped on the clamping plates 41 are conveyed to a composite platform.

The plurality of material conveying devices 2 are longitudinally distributed, and the discharge holes of the plurality of feeding rails 12 are respectively flush with the heights of the corresponding conveying belts 23, and the specific effect is shown in fig. 1. The material sorting device comprises a plurality of material conveying devices 2, a plurality of feeding rails 12, a plurality of conveying belts 23 and a plurality of material sorting devices 3, wherein the plurality of material conveying devices 2 are longitudinally arranged, and the discharge ports of the plurality of feeding rails 12 are respectively flush with the heights of the corresponding conveying belts 23, so that on one hand, the cigarette filter sticks 5 on the feeding rails 12 are sorted to the material conveying devices 2 conveniently by the material sorting devices 3, and when the discharge ports of the plurality of feeding rails 12 are respectively flush with the heights of the corresponding conveying belts 23, the material sorting devices 3 sort the cigarette filter sticks 5 on the feeding rails 12 to the material conveying devices 2, only the cigarette filter sticks need to move in the horizontal position, but do not need to move in the vertical direction, so that the displacement of the material sorting devices 3 during sorting is reduced, and the sorting efficiency of the material sorting devices 3 is improved; on the other hand is for the convenience of material clamping device 4 with the cigarette filter rod 5 centre gripping on material transfer device 2 to compound platform on, if material transfer device 2 transversely sets up, then material clamping device 4 no matter locates that one side, when material transfer device 2 is more, material clamping device 4 all can be difficult to implement to the operation that cigarette filter rod 5 on material transfer device 2 carries out the centre gripping, and with a plurality of material transfer device 2 vertical settings, only need locate a plurality of material transfer device 2 arbitrary one side with material clamping device 4, material clamping device 4 all can carry out the centre gripping to the cigarette filter rod 5 on material transfer device 2, thereby make this mechanism's practicality stronger.

The conveyor belt 23 is provided with a V-shaped groove 231 for limiting the cigarette filter stick 5, and the specific effect is shown in fig. 3. The V-shaped groove 231 is provided on the conveyor belt 23 to limit the position of the cigarette filter stick 5 placed on the conveyor belt 23, and prevent the cigarette filter stick 5 from falling off from the conveyor belt 23 when the conveyor belt 23 rotates, which not only wastes production materials, but also affects the compounding of the cigarette filter stick 5. Since the filter rods 5 are generally cylindrical, if the surface of the conveyor belt 23 is flat, the filter rods 5 are placed on the conveyor belt 23, and when the conveyor belt 23 rotates, the filter rods 5 easily roll on the conveyor belt 23, so that they fall off the conveyor belt 23. The conveyor belt 23 is provided with the V-shaped grooves 231, the material sorting device 3 places the cigarette filter sticks 5 in the V-shaped grooves 231 on the conveyor belt 23, and the V-shaped grooves 231 can limit the cigarette filter sticks 5 and limit the rolling of the cigarette filter sticks, so that the cigarette filter sticks are not easy to fall off from the conveyor belt 23.

The V-shaped grooves 231 are arranged circumferentially along the conveyor belt 23, see fig. 3 for a particular effect. The V-shaped grooves 231 are arranged along the circumferential direction of the conveyor belt 23, on one hand, the positioning accuracy of the material sorting device 3 for placing the cigarette filter sticks 5 in the V-shaped grooves 231 is reduced, because the V-shaped grooves 231 surround the conveyor belt 23 for a circle, the material sorting device 3 only needs to place the cigarette filter sticks 5 at the positions of the V-shaped grooves 231 on the conveyor belt 23, if the V-shaped grooves 231 are arranged along the axial direction of the conveyor belt 23, the material sorting device 3 places the cigarette filter sticks 5 in the V-shaped grooves 231, and the interval between every two V-shaped grooves 231 needs to be considered, so that the positioning accuracy of the material sorting device 3 is improved; on the other hand, in order to facilitate the material holding device 4 to hold the cigarette filter rods 5 on the conveyor belt 23 from the conveyor belt 23 side, if the V-shaped grooves 231 are provided along the axial direction of the conveyor belt 23, it may be difficult for the material holding device 4 to hold the cigarette filter rods 5 placed in the V-shaped grooves 231 on the conveyor belt 23 side.

The slide rail 43 is arranged on one side of the conveyor belt 23 and parallel to the conveyor belt 23, and a plurality of mounting seats 42 fixed with the clamping plates 41 are arranged on the slide rail 43, and the specific effects are shown in fig. 1 and 4. When the plurality of material conveyors 2 are distributed along the longitudinal direction, the slide rail 43 is provided on the side of the plurality of conveyor belts 23 and parallel to the plurality of conveyor belts 23, so that the cigarette filter rods 5 on the conveyor belts 23 are clamped by the clamping plate 41 moving on the slide rail 43. The installation seats 42 fixed with the clamping plates 41 are arranged on the sliding rails 43 to accelerate the clamping efficiency of the material clamping device 4, so that the working efficiency of the material clamping device is accelerated. If only two mounting seats 42 are arranged on the slide rail 43, after the cigarette filter stick 5 on the conveyor belt 23 is clamped by the clamping plate 41, the cigarette filter stick can only be conveyed to the filter stick compounding platform and then returned for clamping the next cigarette filter stick 5, which results in lower working efficiency of the material clamping device 4.

The clamping plates 41 on the plurality of mounting seats 42 extend longitudinally to different lengths, as shown in fig. 4. Because the plurality of material conveying devices 2 are longitudinally distributed, the slide rail 43 is arranged on one side of the plurality of conveyor belts 23 and is parallel to the plurality of conveyor belts 23, and the plurality of installation seats 42 move along the slide rail 43, if the clamping plates 41 on the plurality of installation seats 42 can respectively clamp the cigarette filter sticks 5 on the plurality of conveyor belts 23 which are longitudinally distributed, only the longitudinal extending lengths of the clamping plates 41 on the plurality of installation seats 42 can be matched with the conveyor belts 23 with different heights, so that the clamping plates 41 on the plurality of installation seats 42 can clamp the cigarette filter sticks 5 with different heights. Because a clamping plate 41 is fixed on each mounting seat 42, and when the material clamping device 4 clamps the cigarette filter sticks 5, the clamping plates 41 on two adjacent mounting seats 42 are respectively abutted against two ends of the cigarette filter sticks 5, so that two adjacent mounting seats 42 on the slide rail 43 form a group, the clamping plates 41 on two mounting seats 42 in the same group have the same length extending in the longitudinal direction, and when two mounting seats 42 in the same group are close to each other, the clamping plates 41 on the two mounting seats 42 can clamp the cigarette filter sticks 5.
