[0032] See attached Figure 1 and 2 As shown, the filter rod cutting and cross-section detection device of this embodiment includes a fixed base plate 21 vertically arranged on the ground and a filter rod guiding mechanism, a positioning mechanism, a clamping mechanism, a cutting mechanism and a cross-section detection mechanism arranged on the front and rear sides of the base plate 21.

[0033] The filter rod guide mechanism includes an upper guide tube 17 and a lower guide tube 18, wherein the upper guide tube 17 is vertically fixed to the upper portion of the front side of the base plate 21, and the lower guide tube 18 is vertically and movable left and right arranged at the lower portion of the front side of the base plate 21. The lower guide tube 18 can be moved to a position communicating with the upper guide tube 17 under the drive of the first power mechanism, and a guide channel for the upper filter rod 23 to fall after cutting is provided. Among them, the first power mechanism adopts a first telescopic cylinder 19 arranged at the lower portion of the front side of the base plate 21, and the lower guide tube 18 is connected to the protruding end of the first telescopic cylinder 19, and is controlled to move left and right by the first telescopic cylinder 19.

[0034] In this embodiment, the upper guide tube 17 and the lower guide tube 18 both adopt a vertebral tube structure with a larger upper portion and a smaller lower portion, which can achieve good guidance of the filter rod.

[0035] As a further improvement, the filter rod guide mechanism further includes a light curtain switch 20 with a central opening. The light curtain switch 20 is arranged below the lower guide tube 18 and is located directly below the upper guide tube 17. That is, the light curtain switch 20 does not affect the left and right movement of the lower guide tube 18. When the lower guide tube 18 moves directly below the upper guide tube 17, the central channels of the upper guide tube 17, the lower guide tube 18 and the light curtain switch 20 are connected, providing a falling guide channel for the upper filter rod, and providing a signal to the next process through the detection of the light curtain switch.

[0036] See attached Figure 3 and 4 As shown, in this embodiment, the positioning mechanism includes a positioning support plate 6 and a second power mechanism for controlling the movement of the positioning support plate 6. Driven by the second power mechanism, the positioning support plate 6 can move to the bottom of the upper guide tube 17.

[0037] Specifically, the second power mechanism includes a second motor 1, a lead screw 4, a second slider 5, a second slide rail 3, and a second telescopic cylinder 2. The second motor 1 drives the lead screw 4 to rotate through a conveyor belt, and the lead screw 4 drives the second slider 5 thereon to move along the second slide rail 3. The second telescopic cylinder 2 is fixed on the second slider 5, and the positioning support plate 6 is fixed to the protruding end of the second telescopic cylinder 2. Then, the positioning support plate 6 moves up and down with the second slider 5 under the drive of the second motor 1, that is, the positioning mechanism can be positioned below the upper guide tube 17 according to different filter rod cutting size requirements. For example, the positioning height of the positioning support plate 6 can realize accurate cutting of filter rods at any position in the range of 10-75mm, and the measurable length range of the filter rod is 60-150mm.

[0038] The positioning support plate 6 can move forward and backward under the drive of the second telescopic cylinder 2. The positioning support plate 6 and the second power mechanism are fixed on the rear side of the base plate 21. The base plate 21 is provided with a clearance hole for the positioning support plate 6 to extend forward. In this way, the positioning support plate 6 can extend to the front side of the base plate through the clearance hole and be positioned at the filter rod falling channel of the upper guide tube 17 to receive the filter rod 23.

[0039] See attached Figure 5 and 6 As shown, in this embodiment, the clamping mechanism includes an upper clamping jaw 8 and a lower clamping jaw 28 arranged thereunder, the upper clamping jaw 8 and the lower clamping jaw 28 are arranged between the upper guide tube 17 and the positioning support plate 6, and the upper clamping jaw 8 and the lower clamping jaw 28 are used to clamp and release the filter rod 23 falling from the upper guide tube 17 respectively, and the lower clamping jaw 28 can realize left and right horizontal movement driven by the third power mechanism.

[0040] Specifically, the upper clamping jaw 8 and the lower clamping jaw 28 are controlled to open and close by rotating electromagnets 10 and 30, respectively. More preferably, the rotating electromagnets 10 and 30 are variable torque electromagnets. That is, the variable torque electromagnets 10 and 30 can output a small torque when clamping the filter rod 23 at the beginning to avoid the filter rod 23 being clamped during rapid start-up; but when cutting the filter rod, the torque output can be gradually increased to 4 times to avoid the filter rod 23 rotating during cutting, which can ensure the flatness of the cross section, the measurement results are accurate and reliable, and the quality of the filter rod is improved.

[0041] The third power mechanism includes a third motor 7, a third slide rail 9 and a third slider 24. The lower clamp 28 and the electromagnet 30 for controlling the opening and closing thereof are fixed on the third slider 24, and are moved horizontally left and right along the third slide rail 9 driven by the third motor 7. The third motor 7 is fixed on the rear side of the base plate 21, and the third slide rail 9 is fixed on the front side of the base plate 21. A clearance hole is provided on the base plate 21 for connecting the third motor 7 with the third slider 24.

[0042] In this embodiment, the cutting mechanism includes a blade 15 and a fourth power mechanism for controlling the movement of the blade 15, and is used to cut the filter rod 23 clamped by the clamping mechanism.

[0043] The fourth power mechanism includes a fourth motor 12, a fifth motor 11, a fourth slide rail 13 and a fourth slider 14. The fourth motor 12 drives the fourth slider 14 to move on the fourth slide rail 13, the fifth motor 11 is fixed on the fourth slider 14, the blade 15 is fixed on the fourth slider 14 through a blade fixing frame 16, and the fifth motor 11 drives the blade 15 to rotate.

[0044] The blade 15 and the fourth power mechanism are both fixed on the rear side of the base plate 21, and a clearance hole is provided on the base plate 21 for the blade 15 and the blade fixing frame 16 to extend forward. Then, the blade 15 moves horizontally toward the filter rod along with the fourth slider 14 under the drive of the fourth motor 12, and rotates under the drive of the fifth motor 11 to cut the filter rod 23, and cuts the filter rod 23 into two sections, namely, an upper filter rod and a lower filter rod. After the cutting is completed, the fifth motor 11 controls the blade to stop rotating, and the fourth motor 12 drives the blade 15 to return to its original position.

[0045] In this embodiment, the cross-section detection mechanism includes an image acquisition unit 22. The image acquisition unit 22 is fixed to the upper front side of the base plate 21, and the lower clamping jaw 28 can be moved to the bottom of the image acquisition unit 22 under the drive of the third power mechanism to realize image data acquisition of the cut cross section of the lower filter rod and realize detection of the cross section.

[0046] See attached Figure 7As shown, after the image data acquisition is completed, the lower variable torque electromagnet 28 controls the lower clamping jaw 30 to open, so that the lower filter rod falls into the receiving hopper. At the same time, the first telescopic cylinder 19 controls the lower guide tube 18 to move to the bottom of the upper guide tube 17, and the upper variable torque electromagnet 8 controls the upper clamping jaw 10 to open. The upper filter rod passes through the center hole of the light curtain switch 20 under the guidance of the lower guide cone tube 18. After the light curtain switch 20 senses the filter rod, it sends a signal to the control system to notify the next process to start working.

[0047] The present invention arranges filter rod guiding mechanism, positioning mechanism, clamping mechanism, cutting mechanism and cross-section detection mechanism on the front and rear sides of the base plate, and through the cooperation of the five mechanisms, the filter rod can be easily dropped, positioned and cut, and cross-section detected.
