Further, in this embodiment, the particle discharge bucket 301 is arranged below the front end of the front roller 201, so that the particles on the conveyor belt 202 fall into the particle discharge bucket 301 through the transmission of the conveyor belt 202. When the composite cavity filter rod is produced, the particle discharge bucket 301 is installed in the discharge bucket bracket 302; when the composite cavity filter rod is not produced, the particle discharge bucket 301 can be taken out from the discharge bucket bracket 302, and the discharge bucket bracket 302 and the smoke gun 5 of the forming unit below the discharge bucket bracket 302 are cleaned and maintained.

[0035] Preferably, Figure 4 , Figure 6 As shown, the forming unit smoke gun 5 includes a forming cavity (the forming cavity is not shown), and a transmission cloth belt 503, the bottom end surface of the forming cavity is provided with a transmission cloth belt 503, and the composite cavity filter rod is placed on the transmission cloth belt 503; the shape of the forming cavity is an "Ω" shape with the opening facing upward; the composite cavity filter rod includes a plurality of filter elements 502 and a forming paper 501, the shape of the forming paper 501 is the same as the shape of the forming cavity, and the bottom end of the forming paper 501 abuts against the transmission cloth belt 503; a plurality of filter elements 502 are placed on the forming paper 501, and a cavity 504 is formed between adjacent filter elements 502; the lower end of the particle discharge bucket 301 is provided in the discharge bucket bracket 302, and the lower end of the particle discharge bucket 301 is pressed on the forming paper 501. In this embodiment, glue is coated on the forming paper 501, and the filter element 502 is glued to the forming paper 501 by glue, and the forming paper 501 moves with the transmission cloth belt 503.

[0036] Preferably, Figure 4 , Figure 5 As shown, a bracket hollow cavity 405 is provided at the lower part of the discharge bucket bracket 302, and a plurality of particle recovery ports 401 are provided on the end surface of the bracket hollow cavity 405 close to the molding cavity. In this embodiment, the discharge bucket bracket 302 is stepped, and the bracket hollow cavity 405 is provided at the lower side of the discharge bucket bracket 302, and does not intersect with the particle discharge bucket 301.

[0037] Preferably, Figure 4As shown, the particle recovery mechanism 4 includes a particle recovery port 401, a particle recovery pipe 402, a suction fan 403, and a particle storage box 404.

Further, in this embodiment, there are two particle recovery pipes 402, which are respectively connected to the side walls on opposite sides of the hollow cavity 405 of the bracket. When the suction fan 403 is working, negative pressure appears in the particle storage box 404, and the particles falling on the filter element 502 of the composite cavity filter rod are pressed into the particle recovery pipe 402 by the atmospheric pressure. The particles enter the particle storage box 404 through the particle recovery pipe 402 for storage. After accumulating to a certain amount, the operator re-adds the particles to the feed hopper 1 for reuse.

[0038] Furthermore, a filter is provided at the connection between the suction fan 403 and the particle storage box 404 to confine the particles in the particle storage box 404 and prevent the particles from being sucked into the suction fan 403 and causing damage to the suction fan 403 .

[0039] The utility model relates to a ternary composite cavity filter rod particle adding device, and its working principle is as follows:

[0040] First, the operator adds particles to the feed hopper 1, and the particles fall on the baffle 101. The operator opens the baffle 101 manually or by a control component, and the particles fall from the discharge port of the feed hopper 1 and enter the conveyor belt 202 of the particle conveying mechanism 2. The operator controls the driving source 205 to work through the control component, and the driving source 205 drives the rear roller 203 to rotate through the transmission chain 204, and the rear roller 203 drives the front roller 201 to rotate through the conveyor belt 202, and the particles move on the conveyor belt 202 to the particle discharge bucket 301 below the front roller 201.

[0041] Then, the operator starts the transmission belt 503 through the control component, and the transmission belt 503 drives the filter element 502 and the molding paper 501 to move to the bottom of the particle discharge bucket 301. The particles in the particle discharge bucket 301 fall into the cavity 504 between the adjacent filter elements 502, thereby achieving the purpose of adding particles to the composite cavity filter rod.

[0042] Finally, the operator starts the suction fan 403 through the control component, and the suction fan 403 draws negative pressure into the particle storage box 404. The particles falling on the filter element 502 enter the bracket hollow cavity 405 through the particle recovery port 401 under the action of atmospheric pressure, and then enter the particle storage box 404 through the particle recovery pipe 402 on the bracket hollow cavity 405. After a certain amount of particles are stored in the particle storage box 404, the particles are taken out and added back to the feed hopper 1 to achieve particle recycling.

[0043] Furthermore, the rotation speed of the driving source 205 matches the opening and closing degree of the baffle 101, thereby achieving quantitative control of the particles, which is simple to operate and convenient to use.

[0044] The utility model relates to a ternary composite cavity filter rod particle adding device, which adds solid particles into a feed hopper 1, and the particles pass through a particle transmission mechanism 2 and a particle discharge mechanism 3 and then enter into a cavity 504 of the ternary composite cavity filter rod; at the same time, the utility model can control the particle addition amount by adjusting the rotation speed of a servo motor to achieve quantitative particle addition; the utility model is provided with a particle recovery mechanism 4, which can achieve the recycling of excess solid particles and improve particle utilization efficiency; the particle recovery mechanism 4 adopts negative pressure recovery, which can reduce safety hazards during the working process.
