Description

Technical Field

[0001] This utility model relates to the field of cigarette testing technology, specifically to a rotary cigarette feeding mechanism. Background Technology

[0002] When cigarettes undergo various tests, an automatic cigarette feeding mechanism is required to deliver the cigarettes one by one to the testing position for the testing equipment to perform the tests, and then transfer the cigarettes to other positions for the next cigarette to be tested.

[0003] Taking the inspection of the cigarette's outline as an example, the cigarette needs to be rotated during the inspection process to observe various parameters of the cigarette's outline. For example, the application number is CN202223046317.8, and the name is "Cigarette Appearance Inspection Device". It uses a roller method to realize the rotation and inspection of the cigarette. After the inspection is completed, the rollers are separated and the cigarette falls into the space below, completing the entire process of feeding, inspection and withdrawal.

[0004] However, the method of horizontally offsetting the rollers requires not only a rotating mechanism but also a horizontally moving mechanism. The mechanism is relatively complex and costly, and it lacks cost advantage from an intensive perspective. Further improvements are needed to the cigarette feeding mechanism to provide a new feeding mechanism with a more streamlined structure and satisfactory performance.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a rotary cigarette feeding mechanism with a more streamlined structure and simpler feeding and unloading methods.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a rotary cigarette feeding mechanism, comprising two rotating rollers arranged parallel to each other; The gap formed by the circumferential roller surfaces of the two rotating rollers is the support gap, and the gap width is smaller than the diameter of the cigarette, which is used to support the cigarette. One of the rotating rollers has a notched platform on its surface. The gap formed by the notched platform and the surface of the other rotating roller is the exit gap, and the gap width is greater than the diameter of the cigarette. This gap is used to cause the cigarette to lose support and fall out of the exit gap.

[0008] Based on the above, both rotating rollers have a notched platform on their roller surfaces. During rotation, the notched platform always engages with the circumferential roller surface of the other rotating roller to form the exit gap.

[0009] Based on the above, both rotating rollers have notched platforms on their roller surfaces. During rotation, the two notched platforms always cooperate to form the exit gap.

[0010] Based on the above, the two rotating rollers rotate in the same direction, have the same diameter, and rotate at the same speed.

[0011] Based on the above, the two rotating rollers rotate in opposite directions and both rotate upwards from the gap, forming opposite rotations. The rotation speeds and diameters of the two rotating rollers may be equal or unequal.

[0012] Based on the above, it also includes a horizontal pushing mechanism, which includes a push rod and a drive assembly. The working end of the push rod extends to the support gap between the two rotating rollers for pushing the cigarette stick to move horizontally. The drive assembly is used to drive the push rod to move.

[0013] Based on the above, it also includes a detection component, which is disposed above the support gap, for detecting whether a cigarette has entered, and serves as a trigger start signal for the horizontal pushing mechanism.

[0014] Based on the above, the detection component is a light curtain sensor used to detect the position of the end of the cigarette stick.

[0015] Based on the above, the driving mechanism for the two rotating rollers includes a linear slide, a connecting plate, and a rack. Gears are installed on the drive shafts of the two rotating rollers, and both gears mesh with the rack. The linear slide drives the two gears to rotate through the connecting plate and the rack, thereby driving the two rotating rollers to rotate.

[0016] Based on the above, a recycling trough is provided below the exit gap.

[0017] This invention has substantial features and advancements compared to existing technologies. Specifically, it designs a set of rotating rollers, utilizing the characteristic that the gap between the circumferential roller surfaces of the rotating rollers is smaller than that of a cigarette. This allows a cigarette falling between two rotating rollers to maintain its directionality without falling, and enables the cigarette to rotate under the rotational drive of the rollers, thus enabling the detection of various cigarette parameters. When the detection is complete and the cigarette needs to be removed, the rotating rollers rotate to the position of the notch, causing the gap to widen and unable to support the cigarette, causing it to fall and be removed. This mechanism requires only one set of rotating drive power source and two rotating rollers, resulting in a more streamlined structure, controlled costs, and a simple and stable removal method.

[0018] Furthermore, notched platforms can be set on both rotating rollers, so that the cigarette can be ejected after the rotating rollers have rotated half a circle, or the cigarette can only be ejected when the notched platform is directly facing the roller, providing multiple motion possibilities and adapting to a variety of different working scenarios.

[0019] Furthermore, the movements of the two rotating rollers can be independent of each other or follow each other, and can be adjusted according to the appropriate scenario.

[0020] Furthermore, by adding a horizontal pushing mechanism, the position of the cigarette stick at the support gap can be adjusted.

[0021] Furthermore, by adding detection components, high-precision position adjustment and linkage response can be achieved. Attached Figure Description

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0030] Example 1 like Figures 1-4 As shown, a rotary cigarette feeding mechanism includes two rotating rollers arranged parallel to each other, referred to in this embodiment as the first rotating roller 1 and the second rotating roller 2.

[0031] The gap formed by the circumferential roller surfaces of the two rotating rollers is the support gap 3, and the gap width is smaller than the diameter of the cigarette 4, which is used to support the cigarette 4.

[0032] The first rotating roller 1 has a notched platform 5 on its roller surface. The gap formed by the notched platform 5 and the roller surface of the second rotating roller 2 is the exit gap 6 and the gap width is greater than the diameter of the cigarette. This gap is used to make the cigarette 4 lose support and fall out from the exit gap 6.

[0033] Specifically, in practical applications, there are three situations: like Figure 1 As shown, in the first case, only the first rotating roller 1 has a notched platform 5, and the second rotating roller 2 is a complete circumferential roller surface. When the notched platform 5 rotates to the inner gap, an exit gap 6 is formed. In this case, it usually takes 360 degrees of rotation to form an exit gap.

[0034] like Figure 2 As shown, in the second case, both rotating rollers have notched platforms 5. However, during rotation, the notched platform 5 always engages with the circumferential roller surface of the other rotating roller to form an exit gap. In this case, the exit gap 6 can be formed by rotating the rotating roller half a turn, which is more efficient in continuous operation.

[0035] like Figure 3 As shown, the third case is that both rotating rollers are equipped with notched platforms 5. During the rotation, only when the notched platforms 5 are joined together do they form an exit gap. In this case, the rotating rollers rotate 360 ​​degrees to form an exit gap 6. Its advantage is that the notched platforms 5 can be designed to be relatively smaller and the two rotating rollers can be closer together.

[0036] To facilitate the recycling of the removed cigarettes, a recycling trough 14 is provided below the removal gap.

[0037] In terms of motion design, in this embodiment, the two rotating rollers rotate in the same direction, have the same diameter, and rotate at the same speed. By using the same speed, diameter, and direction, the cigarette can rotate smoothly, which facilitates various detection operations.

[0038] In the drive mechanism, the two rotating rollers can either rotate independently or be synchronously driven by a master and slave drive.

[0039] like Figure 4 As shown, in this embodiment, the driving mechanism for the two rotating rollers includes a linear slide 7, a connecting plate 8, and a rack 9. Gears 10 are provided on the driving shafts of the two rotating rollers, and both gears 10 mesh with the rack 9. The linear slide 7 drives the two gears 10 to rotate through the connecting plate 8 and the rack 9, thereby driving the two rotating rollers to rotate.

[0040] Since there are many ways to drive rotation, synchronization can also be achieved through various transmission methods such as chain drive, belt drive, and gear drive, which will not be listed one by one.

[0041] In other embodiments, the two rotating rollers rotate in opposite directions and both rotate upward from the gap, forming opposite rotations. The rotation speeds and diameters of the two rotating rollers may be equal or unequal.

[0042] Example 2 like Figure 5 As shown, the main difference between this embodiment and embodiment 1 is that it also includes a horizontal pushing mechanism, which includes a push rod 11 and a drive assembly 12. The working end of the push rod 11 extends to the support gap 3 between the two rotating rollers and is used to push the cigarette 4 to move horizontally. The drive assembly 12 is used to drive the push rod 11 to move.

[0043] Its main function is to adjust the horizontal position of the cigarette 4 that falls into the support gap 3, so that it reaches the optimal detection point of the detection device.

[0044] Example 3 like Figure 6 As shown, the main difference between this embodiment and embodiment 2 is that this embodiment also includes a detection component 13, which is disposed above the support gap 3. The detection component 13 is used to detect whether the cigarette 4 has entered, and serves as a trigger start signal for the horizontal pushing mechanism and as a rotation drive signal for the rotating roller.

[0045] In this embodiment, the detection component 13 is a light curtain sensor used to detect the position of the end of the cigarette entering the cigarette, which can determine the position of the end of the cigarette falling, so that the push rod 11 can accurately push the cigarette to the set position.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
