The control signal output end of the PLC control cabinet is connected to the control signal input end of the cutting component.

[0039] The cutting assembly includes a cutting knife 4, a groove wheel 5 and two rotating parts 23. The two rotating parts 23 drive the cutting knife 4 and the groove wheel 5 to rotate respectively. At least one placement groove 6 and a cutting ring groove 7 are provided on the groove wheel 5. The placement groove 6 serves as a cutting position. The cutting knife 4 penetrates into the cutting ring groove 7. The minimum distance between the placement groove 6 and the rotation center of the groove wheel 5 is greater than the minimum distance between the cutting knife 4 and the rotation center of the groove wheel 5. The sizes of the multiple placement grooves 6 are different.

[0040] When cutting, the PLC control cabinet outputs a control signal to the two rotating parts 23, the cutting knife 4 rotates first, and after reaching a stable speed, the groove wheel 5 drives the special filter rod to be tested in the placement groove 6 to rotate together, and the special filter rod to be tested contacts with the cutting knife 4 to complete the cutting operation.

[0045] The special filter rod to be detected is loaded from the silo 2 into between the two support rollers 25, and the segment length acquisition module 1 acquires the segment length information of the special filter rod to be detected and uploads the segment length information to the host computer. After the acquisition is completed, the PLC control cabinet outputs a signal to the pusher 9, and the pusher 9 drives the push plate 8 to achieve the purpose of pushing the special filter rod to be detected, and pushes the special filter rod to be detected between the first support bar 10 and the second support bar 11.

[0047] After the cutting is completed, the cut special filter rod to be inspected enters the placement plate 12 from the feeding channel 13, and the PLC control cabinet outputs a control signal to the second linear moving member 14. The second linear moving member 14 pushes the special filter rod to be inspected on the placement plate 12 to move.

[0049] The loading assembly includes a pushing plate 15, a cam 16, a guide plate 17, a supporting wheel 18 and a rotating motor 19. The rotating shaft of the rotating motor 19 is fixedly connected to the rotation center of the cam 16. The supporting wheel 18 is installed on the cam 16. The first end of the pushing plate 15 is in extrusion contact with the supporting wheel 18. A moving channel 20 is provided on the silo 2. The pushing plate 15 is movably installed in the moving channel 20. The guide plate 17 is installed at the upper end of the moving channel 20. The pushing plate 15 is used to push the special filter rod to be detected in the silo 2 to move to the first end of the guide plate 17. The height of the first end of the guide plate 17 is higher than the height of the second end of the guide plate 17. The second end of the guide plate 17 is located at the section length collection position.

[0050] During loading, the PLC control cabinet outputs a control signal to the rotating motor 19, the rotating motor 19 starts, and drives the push plate 15 to move upward in the moving channel 20 through the cam 16 and the support wheel 18, pushing the special filter rod to be tested to the first end of the guide plate 17, and entering the section length collection position along the guide plate 17.

[0051] The power module of the PLC control cabinet adopts Mean Well NDR-240-24, the CPU module of the PLC control cabinet adopts Inovance AM521-0808TP, the digital input module of the PLC control cabinet adopts Inovance GL20-1600END module, the digital output module of the PLC control cabinet adopts Inovance GL20-0016ETP module, the field bus connecting the host computer and the PLC control cabinet adopts the industrial general ModbusTCP, the field bus connecting the host computer with the section length acquisition module 1 and the cross-section acquisition module 3 adopts EtherCAT, the section length camera adopts Hikvision MV-IMX250-74UM, the cross-section camera adopts Hikvision MV-IMX250-74UM, the rotating part 23 driving the cutting knife 4 adopts Inovance SV-660N, and the driving motor, the first linear moving part 27, and the rotating part 23 of the driving groove wheel 5 all adopt MOONS’ 42BYG250BA.

[0052] The working principle of the multifunctional special filter rod detection control system based on PLC in this utility model is as follows:

[0053] After the PLC control cabinet receives the start measurement command issued by the host computer, it starts to transmit the control signal to the rotating motor 19 to drive the loading component to start, and lifts the special filter rod to be detected in the silo 2 to the segment length collection position. The segment length camera collects the segment length information of the special filter rod to be detected located below it, and transmits the segment length information to the host computer; after the collection is completed, the PLC control cabinet drives the pushing member 9 to push the special filter rod to be detected between the first support bar 10 and the second support bar 11, and then the first linear moving member 27 controls the distance between the first support bar 10 and the second support bar 11 to increase. At this time, the special filter rod to be detected falls into the placement grooves 6 of different sizes of the groove wheel 5, and then the PLC control cabinet transmits signals to the two rotating members 23 to drive the groove wheel 5 and the cutting knife 4 to rotate. After the speed of the cutting knife 4 is stable, the groove wheel 5 rotates 360 degrees. During the rotation of the groove wheel 5, the special filter rod to be detected will also rotate accordingly, and the special filter rod to be detected will contact the cutting knife 4, thereby completing the cutting of the special filter rod to be detected to obtain a cross-section at a specific position.

[0054] After cutting is completed, the special filter rod to be detected falls into the feeding channel 13 due to the action of gravity. During the falling process, the material sensor will detect the special filter rod to be detected. If there is a signal, it means that the sample has dropped successfully. If there is no signal, it means that the sample has failed to drop. At the beginning, the second linear moving part 14 is located at the rightmost limit. After the special filter rod to be detected successfully falls in, the PLC control cabinet transmits a signal to the second linear moving part 14, and the second linear moving part 14 pushes the special filter rod to be detected to the appropriate position. The cross-sectional camera starts to collect the cross-sectional information of the special filter rod to be detected, and transmits the data to the host computer for data processing.

[0055] The technical solution of the present utility model is not limited to the above-mentioned specific embodiments, and all technical variations made according to the technical solution of the present utility model fall within the protection scope of the present utility model.
