Abstract
Description
Technical Field
[0001] This disclosure relates to the field of tobacco material sorting equipment, and in particular to an auxiliary inspection device for sorting impurities in tobacco materials. Background Technology
[0002] In the production of cigarettes, before the cigarettes are rolled, the tobacco must first be prepared to meet the process specifications through a series of processes in the tobacco processing workshop. Among these processes, the stem-and-strip air separation process is one of the most important steps in the tobacco processing production line.
[0003] The stem and stalk air separation equipment is based on the separation theory of fluid mechanics. Based on set process airflow parameters, materials of different densities and shapes undergo different trajectories in the airflow under the action of air force, separating tobacco stems and shreds and removing impurities (hereinafter collectively referred to as stem and stalk removal materials), ensuring the purity of the tobacco shreds and improving the quality of subsequent processing stages. After the tobacco shreds are conveyed into the airflow separation system of the stem and stalk air separation equipment, the system adjusts the airflow so that the heavier stems and stalks fall downwards due to gravity and are ultimately collected in a dedicated stem and stalk collection bin.
[0004] To ensure the separation effect of the air separation equipment and to promptly identify and resolve potential problems during production, checkpoints are typically set up on the production line. After the air separation and screening by the air separation system, operators conduct a centralized screening and inspection of the rejected material to confirm whether it contains impurities, such as small tobacco fragments or other non-tobacco impurities. If any abnormalities are found during the inspection, such as a large amount of unseparated tobacco or other impurities that may affect the sensory quality of the product in the stems, the operator should immediately report to the shift manager so that the parameters of the air separation equipment can be adjusted in a timely manner, the separation effect optimized, and the impurities analyzed and traced to adjust the operating parameters of the production line accordingly.
[0005] However, the screening and inspection process has the following problems: Operators manually pour out the stems and scraps from the collection bucket, spread them out, and carefully screen and inspect them to determine if any impurities are mixed in. The specific method of spreading the stems and scraps involves manually scattering them slightly and spreading them out flat. This method results in uneven spreading of the stems and scraps, is time-consuming and labor-intensive, makes it difficult for operators to conduct a comprehensive inspection, and sometimes fails to detect impurities due to human negligence or misoperation. Furthermore, the cumbersome nature of the inspection process may lead operators to be perfunctory, failing to identify and effectively identify and remove impurities from the stems and scraps in a timely manner.
[0006] The screening and inspection methods described above are unlikely to achieve the desired results in the screening and inspection process, which may result in impurities being mixed in with the finished tobacco, thus increasing the quality risk of the finished tobacco. Utility Model Content

[0013] The slider is movable between a first position and a second position;
[0014] A reset component acts on the slider and is configured to remain in the first position when the triggering part does not trigger the transmission mechanism; when the triggering part triggers the transmission mechanism, the triggering part remains in contact with the slider and drives the slider to move from the first position to the second position.
[0015] A linkage mechanism is provided, wherein the slider is driven to the power input end of the linkage mechanism, the discharge gate is pivotally mounted on the discharge port, and the power output end of the linkage mechanism is connected to the discharge gate, so that the linkage mechanism can rotate with the movement of the slider and drive the discharge gate to rotate relative to the discharge port to open or close the discharge port.
[0016] In some embodiments of auxiliary inspection equipment for sorting impurities in tobacco materials, the triggering part is provided with a first surface, and the slider is provided with a second surface adapted to the shape of the first surface. When the triggering part triggers the transmission mechanism, the first surface and the second surface come into contact and cooperate, and the triggering part guides the slider to move from the first position to the second position through the first surface and the second surface.

The second link can rotate about an axis parallel to the axis of the slide bar and fixed relative to the feed hopper. The two ends of the second link are respectively hinged to the second end of the first link and the first end of the third link. The second end of the third link is connected to the discharge gate and configured to drive the discharge gate to rotate so that the discharge gate opens or closes the feed inlet.
[0019] In some embodiments of auxiliary inspection equipment for sorting impurities in tobacco materials,
[0020] The transmission mechanism includes a slider guide seat, the slider guide seat having a slider guide groove, and the slider being slidably fitted into the slider guide groove; and / or
[0021] The linkage mechanism includes two slide guide seats, each slide guide seat having a guide groove. The guide grooves of the two slide guide seats are respectively slidably engaged with both ends of the slide rod. Each guide groove is configured to guide the end of the corresponding slide rod to move along the moving direction of the slider.
[0022] In some embodiments of the auxiliary inspection equipment for sorting impurities in tobacco materials, the scraping part is rotatably disposed inside the equalizing hopper about an axis perpendicular to the inner wall of the bottom of the equalizing hopper, and the triggering part is disposed on the outer side of the scraping part along the radial direction of the equalizing hopper and can rotate with the scraping part.
[0023] In some embodiments of auxiliary inspection equipment for sorting impurities in tobacco materials, the material leveling device further includes a pushing part, which is movably disposed in the material leveling hopper. The bottom of the material leveling hopper has a discharge port, and the bottom surface of the pushing part is in contact with the inner wall of the bottom of the material leveling hopper. It is configured to push the tobacco material in the material leveling hopper to the discharge port so as to discharge the material from the material leveling hopper through the discharge port.
[0024] In some embodiments of auxiliary inspection equipment for sorting impurities in tobacco materials, the scraping section and the pushing section are arranged to move synchronously.
[0025] In some embodiments of auxiliary inspection equipment for sorting impurities in tobacco materials, the material leveling device includes a motor and a rotating shaft. The rotating shaft is coaxially disposed within the material leveling hopper. The motor is configured to drive the rotating shaft to rotate around its own axis. The scraping part and the pushing part are connected to the rotating shaft and can rotate with the rotating shaft.
[0026] The working principle of the auxiliary inspection device for sorting impurities in tobacco materials disclosed herein is as follows: During one movement cycle of the scraping section, the triggering section moves along with the scraping section. During the movement of the triggering section, the triggering section applies at least one triggering action to the transmission mechanism, causing the transmission mechanism to drive the discharge gate to open the discharge port of the feeding hopper for a period of time. When the discharge port is open, the tobacco material enters the equalization hopper. Because the bottom surface of the scraping section maintains a certain distance from the inner wall of the bottom of the equalization hopper during movement, the tobacco material entering the equalization hopper is slowly spread and thinned on the inner wall of the bottom of the equalization hopper under the action of the scraping section, thereby facilitating the operator to observe whether the tobacco material contains impurities.
[0027] Therefore, the auxiliary inspection equipment for sorting impurities in tobacco materials provided in this disclosure can improve the efficiency and accuracy of the tobacco material screening process, such as the stem and stick screening process, through the coordinated action of the uniform feeding device, the feeding device and the feeding drive mechanism, so that impurities in the material can be identified in a timely and effective manner, thereby reducing the quality risk of the product.

[0043] refer to Figures 1 to 4 The embodiments of this disclosure provide an auxiliary inspection device for sorting impurities in tobacco materials, including a feeding device 1, a uniform feeding device 2, and a feeding drive mechanism.
[0044] The feeding device 1 includes a feeding hopper 11 and a discharge gate 12. The feeding hopper 11 is configured to store tobacco materials to be inspected and has a feeding port.
[0045] The material leveling device 2 includes a material leveling hopper 21 and a scraper 22. The material leveling hopper 21 is configured to receive tobacco material output from the feed port. The scraper 22 is periodically disposed inside the material leveling hopper 21, and the bottom surface of the scraper 22 maintains a preset distance from the inner wall of the bottom of the material leveling hopper 21.
[0046] The feeding drive mechanism includes a triggering part 31 and a transmission mechanism. The transmission mechanism is configured to drive the discharge gate 12 to open or close the feeding port. The triggering part 31 can move with the scraping part 22. In one movement cycle of the scraping part 22, the triggering part 31 applies at least one triggering action to the transmission mechanism. When the triggering part 31 triggers the transmission mechanism, the transmission mechanism drives the discharge gate 12 to open the feeding port. When the triggering part 31 does not trigger the transmission mechanism, the discharge gate 12 closes the feeding port.
[0047] The scraping section 22 can achieve periodic movement by rotating or reciprocating. The tobacco material can be, for example, stem and twig removal material, or other materials requiring screening and inspection for impurities. Optionally, refer to... Figures 1 to 3 The feeding device 1 includes a support 13 and a first guide hopper 14. The support 13 is disposed below the feeding hopper 11 to support the feeding hopper 11. The first guide hopper 14 is disposed inclined downward downstream of the feeding port, and the outlet of the first guide hopper 14 is aligned with the interior of the equalizing hopper 21 so that the tobacco material discharged from the feeding port can enter the equalizing hopper 21 through the first guide hopper 14.
[0048] The working principle of the auxiliary inspection device for sorting impurities in tobacco materials provided in the embodiments of this disclosure is as follows: During one movement cycle of the scraping section 22, the trigger section 31 moves with the scraping section 22. During the movement of the trigger section 31, the trigger section 31 applies at least one triggering action to the transmission mechanism, so that the transmission mechanism drives the discharge gate 12 to open the discharge port of the feeding hopper 11 for a period of time. When the discharge port is open, the tobacco material enters the equalization hopper 21. Since the bottom surface of the scraping section 22 maintains a certain distance from the inner wall of the bottom of the equalization hopper 21 when it moves, the tobacco material entering the equalization hopper 21 is slowly spread and thinned on the inner wall of the bottom of the equalization hopper 21 under the action of the scraping section 22, thereby making it easier for the operator to observe whether there are impurities in the tobacco material.
[0049] Therefore, the auxiliary inspection equipment for sorting impurities in tobacco materials provided in the embodiments of this disclosure can improve the efficiency and accuracy of the tobacco material screening process, such as the stem and stick screening process, through the coordinated action of the uniform feeding device, the feeding device and the feeding drive mechanism, so that impurities in the material can be identified in a timely and effective manner, thereby reducing the quality risk of the product.
[0050] refer to Figure 2 and Figure 3In some embodiments, the transmission mechanism includes a slider 321, a reset member 322, and a linkage mechanism 323. The slider 321 is movably disposed between a first position and a second position. The reset member 322 acts on the slider 321 and is configured to hold the slider 321 in the first position when the trigger 31 does not trigger the transmission mechanism, and when the trigger 31 triggers the transmission mechanism, the trigger 31 remains in contact with the slider 321 and drives the slider 321 to move from the first position to the second position. The slider 321 is driven to the power input end of the linkage mechanism 323. The discharge gate 12 is pivotally mounted at the discharge port, and the power output end of the linkage mechanism 323 is connected to the discharge gate 12 so that the linkage mechanism 323 can rotate as the slider 321 moves and drive the discharge gate 12 to rotate relative to the discharge port to open or close the discharge port.
[0051] In this embodiment, during the periodic movement of the scraper 22, the trigger 31 contacts the slider 321, driving the slider 321 to move. The slider 321 overcomes the force applied by the reset component 322 and moves from the first position to the second position. As the slider 321 moves, it further drives the linkage mechanism 323 to move, thereby driving the discharge gate 12 to rotate to the position where the discharge port is open. As the trigger 31 continues to move, it disengages from the slider 321. Under the action of the reset component 322, the slider 321 moves back from the second position to the first position and remains in the first position, driving the linkage mechanism 323 to move, thereby driving the discharge gate 12 to rotate to the position where the discharge port is closed and remaining in the position where the discharge port is closed.
[0052] refer to Figure 3 In some embodiments, the trigger part 31 is provided with a first surface S1, and the slider 321 is provided with a second surface S2 that is adapted to the shape of the first surface S1. When the trigger part 31 triggers the transmission mechanism, the first surface S1 and the second surface S2 come into contact and cooperate, and the trigger part 31 guides the slider 321 to move from the first position to the second position through the first surface S1 and the second surface S2.
[0053] Based on the contact and cooperation between the trigger part 31 and the slider 321 in this embodiment, the shapes of the first surface S1 and the second surface S2 can be specifically determined according to factors such as the movement cycle of the trigger part 31, the connection method between the slider 321 and the linkage mechanism 323, the specific structure of the linkage mechanism 323, and the time required for the feed port to open within one movement cycle of the trigger part 31.
[0054] refer to Figure 3 In some embodiments, the first surface S1 and the second surface S2 are wedge-shaped surfaces.
[0055] In this embodiment, by setting the first surface S1 and the second surface S2 as wedge-shaped surfaces with mutually adapted shapes, the triggering part 31 can smoothly apply the triggering action to the slider 321.
[0056] refer to Figures 2 to 4 In some embodiments, the transmission mechanism includes a slide bar 324, which can move with the slider 321. The linkage mechanism 323 includes a first link 3231, a second link 3232, and a third link 3233. The first end of the first link 3231 is hinged to one end of the slide bar 324 about the axis of the slide bar 324. The second link 3232 can rotate about an axis parallel to the axis of the slide bar 324 and fixed relative to the hopper 11. The two ends of the second link 3232 are respectively hinged to the second end of the first link 3231 and the first end of the third link 3233. The second end of the third link 3233 is connected to the discharge gate 12 and configured to drive the discharge gate 12 to rotate so that the discharge gate 12 opens or closes the discharge port.
[0057] Optionally, refer to Figure 3 The transmission mechanism includes a slide rod seat 327 disposed on the slider 321, and a slide rod 324 passing through the slide rod seat 327.

The second connecting rod 3232 is rotatably mounted on the bracket 13 about an axis parallel to the axis of the slide rod 324 and whose position is fixed relative to the hopper 11.
[0058] To ensure that the slider 321 moves more smoothly in the preset direction, thereby guaranteeing the reliability of the operation of the slider 324 and the transmission mechanism, refer to... Figure 2 and Figure 3 In some embodiments, the transmission mechanism includes a slider guide seat 328, which has a slider guide groove, and a slider 321 is slidably fitted into the slider guide groove.
[0059] Optionally, refer to Figure 2 and Figure 3 The slider guide seat 328 is mounted on the bracket 13. Optionally, refer to... Figure 2 and Figure 3 The reset component 322 is a spring. One end of the reset component 322 acts on the far end of the slider guide seat 328, and the other end acts on the slider 321.
[0060] Considering the shape characteristics of the slide bar 324 itself, in order to make the slide bar 324 move more smoothly along the direction of the slider 321, thereby ensuring the reliability of the transmission mechanism's operation, reference is made to... Figure 2 and Figure 3In some embodiments, the transmission mechanism includes two slide guide seats 325, each slide guide seat 325 having a guide groove 326. The guide grooves 326 of the two slide guide seats 325 are respectively slidably engaged with the two ends of the slide rod 324. Each guide groove 326 is configured to guide the end of the corresponding slide rod 324 to move along the moving direction of the slider 321.
[0061] Optionally, refer to Figure 2 and Figure 3 Two slide rod guide seats 325 are mounted on the bracket 13, and the guide groove 326 of the slide rod guide seat 325 is a through groove.
[0062] refer to Figure 1 and Figure 4 In some embodiments, the scraper 22 is rotatably disposed inside the equalizer 21 about an axis perpendicular to the inner wall of the bottom of the equalizer 21, and the trigger 31 is disposed on the outer side of the scraper 22 along the radial direction of the equalizer 21 and can rotate with the scraper 22.
[0063] refer to Figure 1 and Figure 4 In some embodiments, the material leveling device 2 further includes a pushing part 23, which is movably disposed in the material leveling hopper 21. The bottom of the material leveling hopper 21 has a discharge port 210. The bottom surface of the pushing part 23 is in contact with the inner wall of the bottom of the material leveling hopper 21 and is configured to push the tobacco material in the material leveling hopper 21 to the discharge port 210 so as to discharge the material leveling hopper 21 through the discharge port 210.
[0064] In this embodiment, the bottom surface of the pushing part 23 and the inner wall of the bottom of the equalizing hopper 21 are tightly fitted without any gaps. The inspected tobacco material can be pushed to the discharge port 210 by the pushing part 23, and then discharged. A collection bucket can be set below the discharge port 210 to collect the tobacco material.
[0065] Optionally, the material leveling device 2 includes a second guide hopper 24 inclined downwards and disposed downstream of the discharge port 210. Material arriving at the discharge port 210 can be discharged from the leveling hopper 21 through the second guide hopper 24.
