Description

Technical Field

[0001] This application relates to the technical field of cigarettes, and more specifically, to a platform suitable for detecting appearance defects of cigarette sticks. Background Art

[0002] During the production process of cigarette sticks, in addition to tobacco shreds, the following main materials are also included, namely cigarette paper, tipping paper, forming paper, and filter rods, which are collectively referred to as "three papers and one rod". Cigarette paper is used to wrap tobacco shreds. The widths of cigarette papers for regular, medium, and slender cigarette sticks are different. Cigarette paper is made into a tubular shape and then slit and wound into a disk shape. Cigarette paper is commonly known as disk paper. After the columnar paper is unwound, it passes through a paper guiding roller and then through a longitudinal knife mechanism for slitting and then re-wound into a disk paper with a thinner width. From the appearance of the cigarette stick, the cigarette paper plays a role in wrapping the tobacco shreds. The cigarette paper plays a very important role in the ignition performance, burning speed, smoking flavor of the cigarette, the appearance of the cigarette stick, and the chemical components of the smoke.

[0003] In the prior art, during the production process of cigarette sticks, it is often necessary to conduct spot checks on cigarette sticks. However, in the existing appearance detection of cigarette sticks, the cigarette sticks are placed on a detection platform, and then the circumference sizes of the same type of cigarette sticks are detected manually by relying on the eyes. This traditional detection method not only has a slow detection speed, but also relying on the eyes for a long time will not only affect the accuracy, but also cause harm to the eyes of the staff.

Detailed implementation manners

[0026] Now, various exemplary embodiments of this application will be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of this application.

[0027] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way serves as a limitation to this application or its application or use.

[0028] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification.

[0029] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0030] This application provides a platform applicable to the detection of appearance defects of cigarette sticks. By using the first arc - shaped detection groove on the detection plate that matches the circumferential dimension of the target cigarette stick, cigarette sticks with a circumferential dimension larger than the standard size are eliminated, and cigarette sticks with a circumferential dimension smaller than the standard size are screened out through the circular accommodation groove formed by the second arc - shaped detection groove on the pressing plate and the first arc - shaped detection groove, enabling the circumferential dimension of the cigarette sticks to be detected conveniently and quickly. Further, this application also drives the detection plate to tilt relative to the platform through the detection - plate driving mechanism, causing the cigarette sticks with a circumferential dimension smaller than the standard size to slide off automatically, realizing the automatic screening of small - size cigarette sticks.

[0031] As Figure 1-2As shown in the figure, the platform provided by the present application for detecting the appearance defects of cigarette sticks includes a detection plate 2 and a pressing plate 22. A plurality of first arc-shaped detection grooves 21 are provided on the top surface of the detection plate 2, and second arc-shaped detection grooves 23 are provided at positions corresponding to the first arc-shaped detection grooves 21 on the bottom surface of the pressing plate 22. The sizes of the first arc-shaped detection grooves 21 and the second arc-shaped detection grooves 23 are both matched with the circumferential size of the target cigarette stick.

[0032] A handle is provided on the top surface of the pressing plate 22, and the pressing plate 22 is buckled to the detection plate 2 through the buckling and reset mechanisms on both sides. In the working state, the first arc-shaped detection groove 21 and the second arc-shaped detection groove 23 are buckled to form a circular accommodating groove.

[0033] Specifically, as shown in Figure 1-3 the figure, the buckling and reset mechanism includes a movable plate 24, a fixed plate 26, a guide rod 27 and a return spring 25. The movable plate 24 is fixed on the side surface of the pressing plate 22, and the fixed plate 26 is fixed on the side surface of the detection plate 2. The guide rod 27 extends downward after passing through the through hole on the fixed plate 26 from the bottom surface of the movable plate 24. The lower end of the guide rod 27 is in a T shape, and the return spring 25 is sleeved on the guide rod 27 and is clamped between the fixed plate 26 and the lower end of the guide rod 27.

[0034] When detecting the circumferential size of the cigarette sticks to be sampled, first manually pull the handle on the pressing plate 22 to make the pressing plate 22 move upward relative to the detection plate 2. The upward movement of the pressing plate 22 drives the movable plate 24 and the guide rod 27 to move upward, and the return spring 25 is compressed. Then, the cigarette sticks to be sampled are sequentially placed into the first arc-shaped detection grooves 21 on the detection plate 2. Those that can be directly placed are to be detected in the next step, and those that cannot be directly placed in the first arc-shaped detection grooves 21 are directly eliminated. After the non-eliminated cigarette sticks are sequentially placed into the first arc-shaped detection grooves 21, release the handle on the pressing plate 22, and use the restoring force of the return springs 25 on both sides to drive the pressing plate 22 to move downward, so that the second arc-shaped detection grooves 23 are buckled with the first arc-shaped detection grooves 21. At this time, the cigarette sticks with a circumferential size close to the standard size will be subjected to a weak pressure from the pressing plate 22 and are not easy to move relatively; the cigarette sticks with a circumferential size smaller than the standard size are not affected by the pressing plate 22 and can move freely. The cigarette sticks with a circumferential size smaller than the standard size can be screened manually.

[0035] On the basis of the above, preferably, as shown in Figure 1 and 2 and Figure 4, the platform applicable to the detection of the appearance defects of cigarette sticks further includes a detection plate driving mechanism. The detection plate is rotatably arranged on the platform through the detection plate driving mechanism, and the detection plate driving mechanism is used to drive the detection plate to tilt relative to the platform.

[0036] Specifically, as shown in Figure 1 and 2As shown, the detection plate driving mechanism includes a limiting component and a rotating support component that are arranged at intervals along the length direction of the first arc-shaped detection groove on the bottom surface of the detection plate.

[0037] The limiting component enables one end of the detection plate 2 to be hinged to the platform 1 as a fulcrum. As Figure 2 shown, the limiting component includes a retaining block 31 fixed on the bottom surface of the detection plate 2 and two limiting blocks 32 fixed on the platform 1 at intervals. The retaining block 31 is rotatably arranged between the upper ends of the two limiting blocks 32 through a rotating shaft.

[0038] The rotating support component includes a support rod 34. The first end of the support rod 34 is hinged to the bottom surface of the detection plate 2, and the second end of the support rod 34 moves relative to the platform 1 through a moving driving component arranged on the platform 1.

[0039] As Figure 2 and 4 shown, the moving driving component includes a slider 3 hinged to the second end of the support rod 34 and a sliding driving component of the slider 3. The sliding driving component includes a motor 35 and a threaded rod 33. A downwardly concave chute 37 is provided on the top surface of the platform 1. Support blocks 36 are respectively provided at both ends of the chute 37. The threaded rod 33 is rotatably inserted through the two support blocks 36. The lower part of the slider 3 is limited in the chute 37 and the upper part of the slider 3 is threadedly connected to the threaded rod 33. The output end of the motor 35 is fixedly connected to the end of the threaded rod 33.

[0040] After clamping the non-eliminated cigarette between the first arc-shaped detection groove and the second arc-shaped detection groove, start the motor 35. Use the motor 35 to drive the threaded rod 33 to rotate. The rotation of the threaded rod 33 drives the slider 3 to slide in the chute 37 towards the limiting component, thereby driving the support rod 34 to rotate. Under the limitation of the limiting component, the support rod 34 drives the detection plate 2 to rotate upward with the limiting component as the fulcrum, and further makes the other end of the detection plate 2 ( Figure 2 shown as the right end in the figure) tilt upward, so that the detection plate 2 has a certain tilt angle. As the slider 3 gradually moves towards the limiting component, the tilt angle of the detection plate 2 gradually increases, so that the cigarette with a circumferential dimension smaller than the standard dimension on the detection plate 2 automatically slides out of the first arc-shaped detection groove 21, realizing the rapid and convenient detection of the circumferential dimension of the cigarette.
