Technical Field
[0001] This utility model relates to the field of tobacco technology, specifically to a real-time weighing and shaking mechanism for an empty tube cigarette lighter. Background Technology
[0002] An empty cigarette dispenser is a research instrument whose main function is to fill an empty cigarette tube with different types of tobacco to make temporary cigarettes. Then, based on various tests and calibrations of the cigarettes, the performance of the temporary cigarettes is evaluated, thereby reflecting the characteristics of different types of tobacco.
[0003] Currently, although the empty tube cigarette dispenser is designed as a special device, its operation mainly relies on manual operation. The process involves weighing a certain amount of tobacco and grouping it, and then using the empty tube cigarette dispenser to inject the same amount of tobacco into an empty cigarette tube to make cigarettes.
[0004] To improve the automation level of empty tube tobacco dispensers, the above processes need to be automated to reduce human intervention. Among them, the weighing, shaking, shaping and dispensing of the quantitative tobacco are essentially continuous actions. How to complete the above processes in a simple and efficient manner is an urgent technical problem to be solved.

The output end of the feeding component is located above the extrusion chamber and does not contact the extrusion chamber, and is used to feed material into the extrusion chamber. The tobacco ejector assembly is located on the side of the extrusion chamber and is used to push out the cylindrical tobacco shreds that have been extruded in the extrusion chamber. The tobacco ejector assembly can be moved to completely separate from the extrusion chamber. The weighing assembly includes a weighing lifting mechanism and a weighing device installed below the movable base. The weighing lifting mechanism drives the weighing device to rise and fall, passing through a hole on the movable base and lifting the movable support and the compression chamber for weighing.
[0008] Based on the above, the extrusion chamber includes a chamber body, guide grooves disposed on both sides of the chamber body, a first semi-circular groove disposed at the rear end of the chamber body, and a push plate guide post disposed on the front end face of the chamber body; The extrusion chamber drive mechanism includes a linear drive mechanism and a push plate.

[0012] Based on the above, the smoking assembly includes two-stage moving platforms. The first-stage moving platform moves along the smoking direction, and the second-stage moving platform moves perpendicular to the first-stage moving platform, which is used to drive the movable slot to engage or disengage with the push handle.
[0013] Based on the above, the shaking assembly includes a shaking cylinder, a track, and the movable base. The shaking cylinder drives the movable base to slide along the track, and the track is laid in a direction perpendicular to the smoke-blowing direction of the smoke-pushing assembly.

[0015] Based on the above, the movable support includes a base plate, a top plate, and a support beam, and the weighing component is positioned at the center of gravity of the movable support.
[0016] Based on the above, the incoming material assembly is a circular vibratory feeder.
[0017] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages: This application incorporates a mechanism around the extrusion chamber that integrates weighing, shaking, extrusion, and smoke pushing functions.

Detailed Implementation
[0027] The technical solution of this utility model will be further described in detail below through specific embodiments.
[0028] like Figures 1-7 As shown, a real-time weighing and shaking mechanism for an empty cylinder smoke generator includes a shaking component 100, a weighing component 200, a forming component 300, a feeding component 400, and a smoke-generating component 500.
[0029] The shaking assembly 100 includes a movable base 101 and a shaking drive mechanism for driving the movable base to shake uniformly in the horizontal direction. In this embodiment, the shaking drive mechanism includes a shaking cylinder 102 and a track 103. The movable base 101 is slidably disposed on the track 103. The length direction of the track 103 is perpendicular to the smoke-discharging direction of the smoke-discharging assembly 500. The tail end of the shaking cylinder 102 is hinged to the whole machine bracket 600, and the other end is hinged to the movable base 101.
[0030] The movable base 101 has a through hole 104 at its center and a vertical guide post 105 on its upper surface. The size of the through hole 104 is larger than the diameter of the weighing device in the weighing assembly 200.
[0031] The main function of the shaking component 100 is to make the tobacco evenly distributed inside the extrusion chamber by horizontal shaking after the tobacco falls into the extrusion chamber, so that the distribution of tobacco is more even and closer to that of real cigarettes after being extruded into a cylinder.
[0032] The molding component 300 includes a movable support 301, an extrusion chamber 302, and an extrusion chamber drive mechanism.
[0033] In this embodiment, the movable support 301 is a three-dimensional structure including a base plate, a top plate, and a support beam. The base plate is provided with a guide hole 303 that cooperates with the guide post 105. Its function is that when the guide post 105 and the guide hole 303 are in the same state, the movable support 301 and the movable base 101 become one unit and can be shaken horizontally under the drive of the shaking component 100. When the movable support 301 rises to the state where the guide post 105 and the guide hole 303 are separated, the movable base 101 does not interfere with the weighing process of the movable support 301.
[0034] The extrusion chamber 302 is fixed to the top of the movable bracket 301. The extrusion chamber drive mechanism is used to drive the extrusion chamber to close. The extrusion chamber drive mechanism and the extrusion chamber are separate structures so that the extrusion chamber can be completely independent of the extrusion chamber drive mechanism.
[0035] Specifically, in this embodiment, the extrusion chamber 302 includes a chamber body 3021, guide grooves 3022 disposed on both sides of the chamber body 3021, a first semi-circular groove 3023 disposed at the rear end of the chamber body 3021, and a push plate guide post 3024 disposed on the front end face of the chamber body.
[0036] The extrusion chamber drive mechanism includes a linear drive mechanism 304 and a push plate 305. The front end of the push plate 305 is provided with a second semi-circular groove 3025 that mates with a first semi-circular groove 3023 to form a circle. Both sides of the push plate 305 are slidably engaged with guide grooves 3022 of the chamber body 3021. The main body of the push plate 305 is provided with push plate guide holes 306 that mate with push plate guide posts 3024. A spring 3026 is provided on the push plate guide posts 3024. A guide post 307 and an anti-collision plug 308 are configured on the side of the linear drive mechanism.
[0037] The working principle of the forming component 300 is as follows: the movable bracket 301 and the extrusion chamber 302 are integrated structures. The linear drive mechanism 304 can be a linear slide, a linear motor, or an electric screw mechanism, etc. The push plate 305 is fixed at the drive end of the linear drive mechanism 304 and guided to the extrusion chamber 302 by the push plate guide post 3024. Then, it enters the extrusion chamber 302 from the side. Through the feeding process, the tobacco shreds dispersed in the extrusion chamber 302 are gathered together and then extruded into a cylinder under the cooperation of the first semicircular groove 3023 and the second semicircular groove 3025.
[0038] When weighing is required, the linear drive mechanism 304 drives the push plate 305 away from the extrusion chamber until it separates from the push plate guide column 3024, so that the movable bracket 301 and the extrusion chamber 302 are independent of the linear drive mechanism 304 and do not affect the weighing.
[0039] The output end of the feeding component 400 is located above the extrusion chamber 302 and does not contact the extrusion chamber 302. It is used to feed material into the extrusion chamber 302. In this embodiment, the feeding component 400 is designed as a circular vibrating plate. The output end is fed to the extrusion chamber 302 through a long groove. The frequency and rhythm of feeding are controlled by vibration to control the amount of tobacco fed in a single time.
[0040] The tobacco-discharging component 500 is disposed on the side of the extrusion chamber 302 and is used to push out the cylindrical tobacco shreds that have been extruded in the extrusion chamber 302. The tobacco-discharging component 500 can be moved to completely separate from the extrusion chamber 302.
[0041] In this embodiment, a push rod 3028 is movably installed on the propulsion side of the first semi-circular groove 3023 in the compartment 3021. A push handle 3027 is provided at the far end of the push rod 3028. The smoke-discharging assembly 500 is correspondingly configured with a movable slot 501 that cooperates with the push handle 3027. The smoke-discharging assembly cooperates with the push handle 3027 through the movable slot 501 to drive the push rod 3028 forward.
[0042] Specifically, in this embodiment, the smoke-dispensing assembly 500 includes two-stage moving platforms. The first-stage moving platform 502 moves along the smoke-dispensing direction, and the second-stage moving platform 503 moves in a direction perpendicular to the first-stage moving platform, which is used to drive the movable slot 501 to engage or disengage from the push handle 3027.
[0043] The working principle of the smoking assembly 500 is as follows: In order to avoid interference with the weighing, the push rod originally belonging to the smoking assembly is integrated into the chamber 3021. When the smoking action needs to be performed, the smoking assembly 500 drives the movable slot 501 to lock the push handle of the push rod, and then moves forward to push out the cylindrical tobacco. When weighing is required, the smoking assembly 500 drives the movable slot 501 to separate from the push handle, without affecting the weighing.
[0044] In other embodiments, the push rod can also be integrated into the smoke-dispensing mechanism and set separately from the chamber. It can be aligned with the smoke-dispensing channel of the chamber by means of position limiting or sensor positioning. When smoke needs to be pushed, it can be moved to the set position and aligned with the smoke-dispensing channel.
[0045] The weighing assembly 200 includes a weighing lifting mechanism 201 and a weighing device 202 installed below the movable base. The weighing lifting mechanism 201 drives the weighing device 202 to lift and lower, so as to pass through the through hole 104 on the movable base 101 and lift the movable support 301 and the compression chamber 302 for weighing.
[0046] In this embodiment, the movable support 301 and the compression chamber 302 are similar to the containers of the weighing device 202, and a tare operation is required when weighing.
[0047] To address the issue of inaccurate weighing due to excessive or insufficient incoming materials, which could lead to waste problems, a waste bin 600 is provided on the push-out side of the bin. When the weighing is not up to standard, the tobacco pushing mechanism pushes the tobacco into the waste bin 600 instead of the empty cigarette tube downstream.
[0048] Overall work process description: The feeding assembly 400 evenly conveys the tobacco shreds into the extrusion chamber. The amount of tobacco shreds input is controlled by intermittent operation. Although the tobacco shreds have undergone preliminary loosening and have been combed to some extent after passing through the vibrating disc, there are still problems of tangling and entanglement, resulting in defects in the single-time weight input control accuracy of the tobacco shreds.
[0049] Therefore, the tobacco needs to be weighed each time the tobacco is smoked.
[0050] During weighing, the entire mechanism is in its initial state. In the initial state, the movable support 301 and the chamber 3021 are not connected to other components. The weighing component 200 is driven to rise, and the weighing device 202 drives the movable support 301 and the chamber 3021 to rise to perform the tare and zeroing operation. Then, after the tobacco falls into the compression chamber, the reading of the weighing device 202 is read to obtain the current weight of the tobacco.
[0051] After weighing is completed, the weighing component descends to its original position, the movable bracket 301 falls into the guide column 105, and the shaking component starts to work to shake the tobacco evenly.
[0052] After shaking for a certain period of time, the forming component 300 starts working, extruding the tobacco into a cylinder. Then the tobacco ejection component 500 starts working, pushing the cylindrical tobacco out from the side with the push rod.
[0053] If the tobacco is of acceptable quality, the connector at the output end of the extrusion chamber connects to the empty cigarette tube downstream, pushing the tobacco into the cigarette tube to make a cigarette. If the tobacco is substandard, the extrusion chamber adjusts its position in advance using the shaking component to push the tobacco into the waste bin.
[0054] 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.
