[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] During the routine debugging of ternary cavity filter rod forming machines, the precise addition of granules and the cleaning of residual granules are major challenges. On the one hand, granules cannot be accurately filled into the cavity; on the other hand, granules cannot be evenly filled into the filter rod. Some overflowing granules cannot be cleaned up in time, causing them to stick directly to the joints of the hot melt adhesive coating on the forming paper, which can easily lead to filter rod bursting. Ultimately, this results in a high percentage of defective products. In addition, overflowing granules accumulate at the tip of the smoke tongue, small pressure plate, and other locations, greatly affecting the normal operation of the equipment. Excess granules cannot be cleaned up without stopping the machine, affecting its operation. Summary of the Invention

[0012] Furthermore, the particle addition and recovery device also includes several excess particle suction devices, which are arranged on the conveyor line of the particle addition device near the recovery chamber; the excess particle suction devices are connected to the first suction pipe through auxiliary suction pipes.

This embodiment discloses a ternary cavity filter rod particle addition and recovery device, such as Figures 1-2 As shown, the device includes a feeding support 1, a storage bin 9, a suction device 2, a vibrating disc 3, a particle adding device 6, and a control device. The suction device 2 is located on the top of the feeding support 1. The storage bin 9 is located on one side of the feeding support 1 and connected to the top of the suction device 2, storing particles. The vibrating disc 3 is located below the suction device 2, and a vibrator 4 is located below the vibrating disc 3. The particle adding device 6 is located on one side of the vibrator 4, and a drive motor 8 is located on the other side, providing power to the particle adding device 6. The suction device 2 is connected to the particle adding device 6 and conveys particles into it. The particle adding device 6 provides and collects excess particles for the ternary cavity filter rods on the lower conveyor line. The ternary cavity filter rods are in close contact with the lower end of the particle adding device 6. The vibrating disc 3 is equipped with a screen, and a material sensor 17 is provided on the inner wall of the vibrating disc 3. A discharge port 14 is provided at the lower part of the outer wall of the vibrating disc 3, and a discharge pipe 11 is provided between the discharge port 14 and the particle adding device 6. The control device is connected to the vibrator 4, the suction device 2, and the material sensor 17 respectively, and is also used to collect the conveying speed of the conveyor line of the ternary cavity filter rod.

[0019] The lower end of the feeder 2 is also provided with a discharge baffle 16. One end of the discharge baffle 16 is a circular cover plate, and the other end is provided with a balance block. When there is no granular material above the circular cover plate, the discharge baffle 16 can automatically close the discharge port at the lower end of the feeder 2.

[0020] A first suction pipe 10 is provided between the storage box 9 and the suction device 2. One end of the first suction pipe 10 is connected to the top of the suction device 2, and the other end passes through the top of the storage box 9 and is inserted into the bottom of the storage box 9. A suction hole is provided on the end side wall.

[0021] The particle adding device 6 is provided with a feeding channel 12 and a recovery chamber 15. The feeding channel 12 is located on one side of the particle adding device 6 and has a through-hole structure. The recovery chamber 15 is located on the other side of the particle adding device 6, and a particle collection port is provided at the bottom of the recovery chamber 15. The ternary cavity filter rod first passes through the port of the feeding channel and then through the particle collection port. The particle adding device 6 is also provided with a recovery channel 13, which is located above the recovery chamber 15 and communicates with it. A second suction pipe is provided between the suction device 2 and the recovery channel 13. Solenoid valves are respectively provided between the suction device 2 and the first suction pipe 10 and the second suction pipe. Two moving auxiliary guide rails 5 are provided between the particle adding device 6 and the vibrator 4 for fine-tuning the relative position between the particle adding device 6 and the ternary cavity filter rod.

[0022] The recycling chamber 15 is equipped with a particle recycling disc 7, which is similar to a gear structure. The particle recycling disc 7 is connected to the drive motor 8 via a transmission shaft. The recycling channel 13 is connected to the feeder 2 via a second suction pipe. Particle material enters the lower ternary cavity filter rod through the feeding channel 12. Due to the continuous supply of material through the filling channel, there are too many particles in the ternary cavity filter rod. As the conveyor line runs, when the filled ternary cavity filter rod moves to the particle collection port, the rotation direction of the lower end of the particle recycling disc 7 is exactly opposite to the running direction of the conveyor line. The particle recycling disc 7 squeezes the excess particles into the recycling chamber 15 through reverse rotation. Under the action of the negative pressure airflow generated by the feeder 2, the particles return to the vibrating disc 3 through the recycling channel 13 and the second suction pipe.

[0023] The material sensor 17 is set at a predetermined distance above the screen and is used to detect the height of the particle feeding. The feeding height can be adjusted through the control panel of the control device. When the particle level is lower than the predetermined height, the material sensor 17 sends a suction signal, and the solenoid valve between the suction device 2 and the first suction pipe 10 opens. The particles in the storage box 9 are sucked into the vibrating plate 3 by negative pressure airflow. After the material sensor 17 detects that the material has reached the predetermined height, the solenoid valve between the suction device 2 and the first suction pipe 10 closes, and the suction stops.

[0024] Granular material enters the screen above the feeder 2 through the discharge port below the feeder 2. The vibrator 4 is controlled by a digital frequency modulation vibration feeder controller. The amount of granules added is adjusted by adjusting the vibration frequency of the vibrating disc 3. The digital frequency modulation vibration feeder controller is installed in the control device, and the vibration frequency and vibration intensity can be adjusted through the control panel of the control device.

[0025] The particle addition and recovery device also includes several excess particle suction devices. The excess particle suction devices are arranged on the conveyor line of the particle addition device 6 near the recovery chamber 15, and are used to absorb the particles remaining after being recovered by the particle recovery disc 7. The excess particle suction devices are connected to the first suction pipe 10 through auxiliary suction pipes to recover the recovered residual particles into the storage box 9.

[0026] The working method of the present invention includes the following steps: S1. The solenoid valve between the feeder 2 and the first suction pipe 10 is opened, and the negative pressure airflow generated by the feeder 2 draws the particles into the vibrating plate 3; when the material sensor 17 detects that the particle level is lower than the set height, it sends a suction signal, and the solenoid valve between the feeder 2 and the first suction pipe 10 is opened; when the material is detected to have reached the set height, the solenoid valve between the feeder 2 and the first suction pipe 10 is closed, and the suction stops. S2. After the particles enter the vibrating disc 3, the vibrator 4 adjusts the amount of particles added by adjusting the vibration frequency of the vibrating disc 3, so that the particles enter the particle adding device 6 through the discharge port 14 and the discharge pipe 11 after being screened by the screen; the particles are transported to the feeding channel 12 of the particle adding device 6 by the suction device 2, and then enter the ternary cavity filter rod below. S3. Due to the continuous feeding of the feeding channel 12, there are too many particles in the ternary cavity filter rod. When the filled ternary cavity filter rod moves to the particle collection port, the particle recovery disc 7 squeezes the excess particles into the recovery chamber 15 by reversing. The solenoid valve between the feeder 2 and the second feed pipe is opened to generate negative pressure airflow, which returns the particles to the vibrating disc 3 through the recovery channel 13 and the second feed pipe. S4. When the ternary cavity filter rod moves to the excess particle feeder, the excess particle feeder uses negative pressure airflow to collect the residual particles into the storage box 9 through the auxiliary suction pipe.

[0027] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
