[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] like Figures 1 to 7As shown, the present invention provides an ultrasonic detection system, comprising: a bracket 1, a silo 2, a toggle mechanism 3, a discharging mechanism 4 and an ultrasonic detection mechanism; the silo 2 is arranged on the bracket 1, and a plurality of filter rods are stored in the silo 2; a discharging port 21 is provided at the bottom of the silo 2; the discharging mechanism 4 is arranged inside the silo 2, the discharging mechanism 4 is arranged close to the bottom of the silo 2, and the discharging mechanism 4 is arranged above the discharging port 21; the ultrasonic detection mechanism is arranged at the discharging port 21, and the ultrasonic detection mechanism is suitable for emitting ultrasonic waves to the filter rods dropped out of the discharging port 21, detecting the shape and diameter of the filter rods by ultrasonic waves, and judging whether the filter rods have defects by detecting the detected shape and diameter; the ultrasonic detection mechanism can detect whether the filter rods have defects without damage when the filter rods fall, and can accurately detect the filter rods, so as to pick out the defective filter rods and ensure the quality of the filter rods.

[0057] The discharge port 21 can temporarily receive the filter rod, for example, a plate-shaped part that can be driven to rotate, so that the ultrasonic detection mechanism can detect the filter rod. The ultrasonic detection mechanism is suitable for emitting ultrasonic waves to the filter rod, detecting the diameter and length of the filter rod by ultrasonic waves, and detecting whether the filter rod is deformed by ultrasonic waves. When the filter rod is not deformed and the length and diameter meet the preset requirements, the filter rod is judged to be qualified. If the conditions are not met, the filter rod is judged to be defective.

[0058] The filter rod in this embodiment is a special-shaped filter rod, which is easy to get stuck in the silo 2 during the discharging process. Due to the presence of notches, through grooves, etc. on the outer wall of the special-shaped filter rod, the special-shaped filter rods may get stuck together in the silo 2, resulting in the inability to discharge materials individually during the discharging process, and the inability to discharge materials when stuck together in the silo 2. If two special-shaped filter rods are stuck together, the discharging mechanism 4 may get stuck when passing through the discharging mechanism 4, which affects the discharging. The toggle mechanism 3 is arranged inside the silo 2, and the toggle mechanism 3 is arranged above the discharging mechanism 4; the toggle mechanism 3 is suitable for toggling the filter rods one by one into the discharging mechanism 4, so that the materials fall one by one from the discharging port 21, and the toggle mechanism 3 is suitable for toggling the materials in the silo 2; the filter rods in the silo 2 are transported out one by one, and the filter rods can be prevented from getting stuck in the silo 2, ensuring the discharging efficiency and smooth discharging of the filter rods.

[0059] When the filter rod is moved by the moving mechanism 3, the filter rod will be squeezed, which may cause deformation and defects of the filter rod. Therefore, before the filter rod falls out of the discharge port 21, the filter rod is inspected to determine whether the filter rod is squeezed and deformed. The ultrasonic detection mechanism and the discharge mechanism 4 are connected to a control module.

[0060] The width of the silo 2 is adapted to the length of the filter rods, so that the filter rods are stacked together after entering the silo 2, and the filter rods can be in a parallel state, which is convenient for discharging.

[0061] The filter rod is a special-shaped filter rod, and notches are arranged on the surface of the filter rod. The notches are arranged along the radial direction of the filter rod. The filling degree of the tow inside the filter rod is changed by means of built-in holes and external deformation of the filter rod, which not only improves the filtering and adsorption capacity of the filter rod, but also increases the unique appearance of the filter rod. Without adding other auxiliary materials, the movement mode of smoke in the filter rod is changed by means of built-in holes and external deformation, thereby improving the filtering and adsorption capacity of the filter rod; however, the special-shaped filter rod may be stuck in the notches on the surface of other filter rods in the silo 2, resulting in the failure of the discharging mechanism 4 to guide the special-shaped filter rod to the discharging port 21. The filter rods may be stuck in the silo 2 and cannot be removed from the material bin 2, which may cause the material to be removed from the material bin 2 by accident. When smoke moves in the special-shaped filter rod, it will inevitably go to the place with less resistance. The internal holes and external deformation of the special-shaped filter rod will change the resistance distribution inside the special-shaped filter rod. The place with holes must have less resistance, so the smoke will move horizontally from the special-shaped filter rod to the holes. In the process of lateral movement, the harmful substances in the smoke and the fibers in the special-shaped filter rod will collide more with each other, and there will be more sedimentation in the special-shaped filter rod and physical interception by the fibers, which will improve the adsorption capacity of the special-shaped filter rod.

[0062] A guide plate 22 is arranged in the silo 2, and the guide plate 22 is arranged obliquely, and the guide plate 22 is inclined toward the discharge mechanism 4; the inclined guide plate 22 can guide the special-shaped filter rod to the discharge mechanism 4, and the special-shaped filter rod can roll toward the discharge mechanism 4 to facilitate discharge.

[0063] The toggle mechanism 3 includes: a fixed member 31 and a rotating member 32; the fixed member 31 is arranged on the inner wall of the silo 2; a through hole 311 is opened on the fixed member 31, the rotating member 32 is rotatably arranged in the through hole 311, and the rotating member 32 extends from the side wall of the through hole 311 to the top of the discharging mechanism 4; the through hole 311 can facilitate the rotation of the rotating member 32; a torsion spring is arranged between the rotating member 32 and the through hole 311; the top surface of the rotating member 32 is inclined, and the top surface of the rotating member 32 is inclined downward; the bottom surface of the rotating member 32 is provided with a first protrusion 321; the bottom surface of the rotating member 32 is provided with a through groove 322, and the through groove 322 is located at the discharging mechanism 4 The through slot 322 can facilitate the special-shaped filter rod to roll toward the rotating wheel 42 when the rotating plate rotates upward; the through slot 322 is provided with a second protrusion 323 on the side wall close to the first protrusion 321; a paddle 324 is rotatably provided on the end of the rotating member 32 away from the fixing member 31; a baffle 325 is vertically provided on the rotating member 32, and the baffle 325 is provided close to the inner wall of the silo 2, that is, the height of the baffle 325 can be adapted to the height of the silo 2, the baffle 325 is close to one side wall in the length direction of the silo 2, and the special-shaped filter rod enters the silo 2 and is stored between the baffle 325 and the other side wall in the length direction of the silo 2; in the initial state, the paddle 324 can contact the stopper 41 The top surface of the stopper 41 is disengaged from the paddle 324 as the rotating member 32 rotates. When the paddle 324 lifts the rotating member 32 to the highest point, the distance between the paddle 324 and the top surface of the stopper 41 is large enough for a shaped filter rod to pass through. At this time, the shaped filter rod will roll toward the rotating wheel 42 and enter between the two shaped filter rods. After the shaped filter rod 43 is disengaged from the first shaped filter rod, the rotating member 32 will instantly rotate downwards through the torsion spring to move the next shaped filter rod to the top surface of the stopper 41. The rod blocking ensures that only one special-shaped filter rod can roll between the two protrusions 43 at a time, and at this time the paddle 324 will contact the top surface of the stopper 41. Since the top surface of the stopper 41 is inclined, the paddle 324 is rotated in the direction of the roller, and the paddle 324 can assist the special-shaped filter rod to roll between the two protrusions 43, so that the special-shaped filter rods can enter between the two protrusions 43 one by one, and the special-shaped filter rods can be discharged one by one; when the first protrusion 321 is lifted up, the baffle 325 will move closer to the side wall of the silo 2, so that the space for storing the special-shaped filter rods is increased, so that the special-shaped filter rods that may be stuck together are separated, so that the special-shaped filter rods can fall one by one into the discharge mechanism 4, and ensure that the special-shaped filter rods in the silo 2 can be discharged completely and one by one;A detection module, such as a photoelectric module, a camera, etc., can be provided below the discharge port 21 to determine whether there are any special-shaped filter rods falling from the discharge port 21. When no special-shaped filter rod is detected to fall, the rotating wheel 42 can be controlled to rotate clockwise, and the protrusion 43 will contact the second protrusion 323 to rotate the rotating plate downward, so that the baffle 325 rotates counterclockwise downward. If there is a special-shaped filter rod stuck in the silo 2 at this time, the baffle 325 will squeeze the special-shaped filter rod downward to loosen the special-shaped filter rod that was originally stuck together, and the material can continue to be discharged. At this time, if no special-shaped filter rod is detected to fall after the preset time, it is determined that the silo 2 has been completely discharged, and a new special-shaped filter rod can be transported into the silo 2 for discharge. ;
