[0019] The lower end of the suction device 2 is also provided with a material discharge baffle 16, one end of which 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 material discharge baffle 16 can automatically close the discharge port at the lower end of the suction device 2.

[0020] A first suction pipe 10 is provided between the material 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 material storage box 9 and is inserted into the bottom of the material storage box 9, and a suction hole is provided on the side wall of the end.

[0021] The particle adding device 6 is provided with a feeding channel 12 and a recovery material chamber 15, wherein the feeding channel 12 is provided on one side of the particle adding device 6 and is a through-hole structure, and the recovery material chamber 15 is provided on the other side of the particle adding device 6, and a particle collecting port is provided at the bottom of the recovery material chamber 15, and the ternary cavity filter rod first passes through the port of the feeding channel and then passes through the particle collecting port; the particle adding device 6 is also provided with a recovery material channel 13, wherein the recovery material channel 13 is provided at the upper part of the recovery material chamber 15 and is connected with the recovery material chamber 15; a second suction pipe is provided between the suction device 2 and the recovery material channel 13, and solenoid valves are provided between the suction device 2 and the first suction pipe 10 and the second suction pipe respectively; two movable 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 recovery cavity 15 is provided with a particle recovery disk 7, which is similar to a gear structure and is connected to the drive motor 8 through a transmission shaft; the recovery channel 13 is connected to the suction device 2 through a second suction pipe. The particle material enters the three-dimensional cavity filter rod below through the feeding channel 12. Since the filling channel continuously provides materials, there are too many particles in the three-dimensional cavity filter rod. As the conveyor line runs, the filled three-dimensional cavity filter rod moves to the particle collection port. At this time, the rotation direction of the lower end of the particle recovery disk 7 is just opposite to the running direction of the conveyor line. The particle recovery disk 7 squeezes the excess particles into the recovery cavity 15 by reversing. Under the action of the negative pressure airflow generated by the suction device 2, the particles return to the vibration disk 3 through the recovery channel 13 and the second suction pipe.

[0023] The material sensor 17 is arranged at a set 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 material level is lower than the set 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, and the particles in the storage box 9 are sucked into the vibrating material plate 3 through the negative pressure airflow. After the material sensor 17 detects that the material has reached the set height, the solenoid valve between the suction device 2 and the first suction pipe 10 is closed to stop suctioning.

[0024] The granular material enters the top of the screen through the discharge port below the suction device 2. The vibrator 4 is controlled by a digital frequency modulation vibration feeding controller, and the amount of granule added is adjusted by adjusting the vibration frequency of the vibration plate 3. The digital frequency modulation vibration feeding controller is arranged 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 adding and recovering device also includes a plurality of excess particle suckers, which are arranged on the conveying line of the particle adding device 6 close to the recovery chamber 15, and are used to absorb the particles remaining after being recovered by the particle recovery plate 7; the excess particle suckers are connected to the first suction pipe 10 through an auxiliary suction pipe, and the recovered residual particles are recovered into the storage box 9.

[0026] The working method of the present invention comprises the following steps: S1. The electromagnetic valve between the suction device 2 and the first suction pipe 10 is opened, and the negative pressure airflow generated by the suction device 2 sucks the particles into the vibrating material plate 3; when the material sensor 17 detects that the particle material level is lower than the set height, a suction signal is issued, and the electromagnetic valve between the suction device 2 and the first suction pipe 10 is opened; when it is detected that the material reaches the set height, the electromagnetic valve between the suction device 2 and the first suction pipe 10 is closed, and the suction is stopped; S2. After the particles enter the vibrating material plate 3, the vibrator 4 adjusts the amount of particles added by adjusting the vibration frequency of the vibrating material plate 3, so that the particles are screened by the screen and then enter the particle adding device 6 through the feed port 14 and the feed pipe 11; the particles are transported to the feeding channel 12 of the particle adding device 6 through the suction device 2, and then enter the three-element cavity filter rod below; S3. Due to the continuous feeding of the feeding channel 12, there are too many particles in the three-dimensional cavity filter rod. When the filled three-dimensional cavity filter rod moves to the particle collection port, the particle recovery plate 7 squeezes out the excess particles into the recovery material cavity 15 by reversing, and the solenoid valve between the suction device 2 and the second suction pipe is opened to generate negative pressure airflow, and the particles are returned to the vibration material plate 3 through the recovery material channel 13 and the second suction pipe; S4. When the ternary cavity filter rod moves to the excess particle suction device, the excess particle suction device recovers the residual particles into the storage box 9 through the auxiliary suction pipe by means of negative pressure airflow.

[0027] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it 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 on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
