[0043] The present application provides a cigarette wrinkle defect detection device. A plurality of cigarette receiving grooves are provided on a first belt, and a wrinkle defect detection mechanism is arranged above the first belt. With the operation of the first belt, automated batch detection is achieved, improving the detection efficiency. Moreover, by using a second belt running in the opposite direction to the first belt, the cigarette rotates while moving along with the first belt, enabling all circumferential positions to be detected when it passes through the wrinkle defect detection mechanism, achieving full - range detection and improving the accuracy of wrinkle defect detection.

[0044] As shown in Figure 1 the cigarette wrinkle defect detection device provided by the present application includes a feeding component, a conveying component, and a wrinkle defect detection mechanism.

[0045] As an embodiment, as shown in Figure 1-3 and 5, the feeding component includes a blanking box 19 and a blanking pipe 17. A support platform 18 is provided on the outer side of the frame 1 of the transmission component. The upper surface of the support platform 18 is fixedly connected to the bottom surface of the blanking box 19. The blanking box 19 contains a plurality of cigarettes to be tested. The bottom surface of the blanking box 19 is inclined downward towards the first belt of the conveying component (see the following description), and a through - hole for the cigarette to pass through is provided at the lowest point of the bottom surface. The blanking pipe 17 is arranged outside the through - hole, and the shape and size of the blanking channel in the blanking pipe 17 match those of the through - hole and the cigarette. The blanking pipe 17 includes an inclined section with the same inclination as the bottom surface of the blanking box 19 and a vertical section. The lower end of the vertical section forms the discharge port of the feeding component, and the discharge port is directly opposite to one of the cigarette receiving grooves 31 on the first conveyor belt.

[0046] Preferably, as shown in Figure 1As shown, the feeding assembly further includes a storage box 20 for storing cigarette sticks, and the blanking box 19 is located between the storage box 20 and the blanking pipe 17.

[0047] As an embodiment, as Figure 7 shown, the bottom of the storage box 20 is connected to the bottom of the blanking box 19 through a mortise and tenon structure.

[0048] Preferably, as Figure 5 and 7 shown, the side of the storage box 20 close to the blanking box 19 is hollowed out and provided with a slot 21. In the non-working state, a plug board 22 is inserted into the slot 21; in the working state, the plug board 22 is pulled out, so that the cigarette sticks in the storage box 20 enter the blanking box 19, thereby increasing the one-time discharge amount of the feeding assembly and improving the efficiency.

[0049] Preferably, a placement box 23 is further provided on the support platform 18 for placing the blanking box 19, which is used as other spare containers for storing cigarette sticks.

[0050] As an embodiment, as Figure 1-5 shown, the conveying assembly includes a first belt 3 and its first driving mechanism, and a plurality of parallel cigarette stick receiving grooves 31 are provided on the first belt 3. The discharge port of the feeding assembly is arranged above the first belt 3. A belt support plate 15 is installed on the top of the frame 1, and the wrinkle defect detection mechanism 16 is fixed on the belt support plate 15 after crossing the first belt 3, so that the wrinkle defect detection mechanism 16 is arranged above the first belt 3 and is located downstream of the discharge port. Thus, the cigarette sticks output by the feeding assembly enter the cigarette stick receiving grooves 31 one by one and enter the wrinkle defect detection mechanism 16 along with the first belt 3 for detection.

[0051] Preferably, the conveying assembly further includes a second belt 14 and its second driving mechanism. The second belt 14 is arranged in the space surrounded by the first belt 3, and the running direction of the second belt 14 is opposite to that of the first belt 3. The middle of the cigarette stick receiving groove 31 is hollowed out. In the working state, the top surface of the second belt 14 is attached to the bottom of the cigarette sticks located in the cigarette stick receiving groove 31, so that the cigarette sticks in the cigarette stick receiving groove 31 rotate under the action of the second belt 14 while moving forward along with the first belt 3, so that all circumferential positions of the cigarette sticks are detected during the process of the cigarette sticks passing through the wrinkle defect detection mechanism 16, realizing all-round detection.

[0052] Preferably, a transmission mechanism is provided between the first driving mechanism and the second driving mechanism.

[0053] As an embodiment, as Figure 2-4 shown, the first driving mechanism includes a motor 6 fixed on the frame 1 and two first rollers 2 rotatably arranged on the frame, and one of the first rollers 2 ( Figure 1The first roller (shown in the middle as being close to the feeding component) is fixedly connected to the output shaft of the motor 6 through a connecting shaft 4. The second driving mechanism includes a driven sub-wheel 13 and two second rollers 11 driven by the driven sub-wheel 13.

[0054] The conveying mechanism includes a driving wheel 5, a driving sub-wheel 8, a driven wheel 10, and a gear chain 9 wrapped around the driving wheel 5 and the driving sub-wheel 8. The output shaft of the motor 6 is fixed in the central hole of the driving wheel 5. A fixed shaft 7 is rotatably installed on the side wall of the frame 1. The driving sub-wheel 8 and the driven wheel 10 are coaxially connected through the fixed shaft 7, and the driven wheel 10 meshes with the driven sub-wheel 13. Thus, after the motor 6 is started, the first roller 2 is driven by the connecting shaft 4 to drive the first belt 3 to run forward. Cigarettes are successively dropped into the cigarette receiving grooves from the lower discharge port of the blanking pipe 17. At the same time, the motor 6 drives the second driving mechanism through the transmission component to drive the second belt 14 to run backward.

[0055] A plurality of detection positions are arranged along the running direction of the first belt 3 in the wrinkle defect detection mechanism 16. The detection principle of each detection position is the same as the existing cigarette wrinkle defect detection principle, and will not be elaborated here. For the same cigarette, if the detection result of at least one of the detection positions is that there is a wrinkle defect, then the cigarette is unqualified.

[0056] As Figure 1 and 6 shown, a deflector 25 that rotates relative to the frame 1 is provided at the discharge end of the first belt 3.

[0057] The driving mechanism of the deflector 25 includes a controller, a cylinder 29, a first connecting rod 27, a second connecting rod 26, and a main shaft 24. The cylinder 29 is fixed on the outside of the side frame at the discharge end. The end of the piston rod of the cylinder 29 is fixedly connected to the first end of the first connecting rod 27 through a plug-in member 28. The second end of the first connecting rod 27 is hinged to the first end of the second connecting rod 26. The second end of the second connecting rod 26 is fixedly connected to the main shaft. The main shaft 24 extends along the width direction of the first belt 3, and both ends of the main shaft 24 are rotatably provided at the upper ends of the support rods 30. The lower ends of the support rods 30 are fixed on the ground.

[0058] The deflector 25 is arranged between the discharge end and the main shaft 24. The outer edge of the body of the deflector 25 is fixedly connected to the main shaft 24. The width of the deflector 25 is the same as the length of the cigarette receiving groove 31. Limiting plates perpendicular to the body are provided at positions corresponding to both ends of the cigarette receiving groove 31 on the deflector 25, forming a U-shaped groove for the cigarettes to pass through. A qualified cigarette collection box and an unqualified cigarette collection box are respectively provided inside and outside the main shaft.

[0059] The controller is respectively in signal connection with the wrinkle defect detection mechanism 16 and the actuator of the cylinder 29. The controller controls the flipping of the deflector 25 according to the detection result of whether the cigarette is qualified given by the wrinkle defect detection mechanism 16.

[0060] After the wrinkle defect detection mechanism 16 detects the cigarettes in the cigarette receiving slot, if the wrinkle defect detection mechanism 16 detects that the cigarette has wrinkle defects, that is, the cigarette is unqualified, the controller controls the cylinder 29 to push the first connecting rod 27 to move, thereby pushing the second connecting rod 26 to flip upward, and driving the main shaft 24 and the guide plate 25 to flip upward and away from the discharge end, so that the unqualified cigarettes cannot fall on the guide plate 25 after being output from the first belt 3, but fall into the unqualified cigarette collection box below the gap between the discharge end and the guide plate 25, and then the controller controls the cylinder 29 to retract and the guide plate 25 returns to its original position. If the cigarette is qualified, the controller controls the cylinder 29 not to move, so that the cigarette falls into the qualified cigarette collection box, so as to facilitate the separation of qualified and unqualified cigarettes after detection.

[0061] The present application replaces manual and semi-automatic inspection with automated batch inspection of cigarettes, greatly improving the efficiency of cigarette wrinkle defect inspection. At the same time, the second belt drives the cigarettes to rotate while moving, achieving all-round inspection and improving the inspection accuracy.

[0062] Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are only for illustration, not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
