Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to a tobacco storage box for a packaging machine in tobacco processing equipment. Background Technology

[0002] Tobacco processing equipment mainly includes humidification equipment, drying equipment, deformation processing equipment, cigarette rolling machines, filter tip assembly machines, filter rod forming machines, and packaging machines. Among them, the packaging machine is a key piece of equipment for achieving continuous production in the cigarette industry. It uses a combination of mechanical transmission and pneumatics to complete the three-stage packaging process of small boxes, cartons, and cases. The principle of the packaging machine is to send the cigarettes produced by the cigarette rolling machine into the cigarette storage compartment of the packaging machine. The cigarettes in the compartment are then packaged into packs in a 7-6-7 arrangement, and then further packaged into cartons.

[0003] However, when cigarettes in the cigarette storage area are arranged and packaged into packs, they are prone to becoming skewed. This can lead to cigarettes breaking, deforming, or failing to fit into the packaging boxes due to breakage or deformation. In some cases, the packaging machine may even jam due to the skewed cigarettes, severely impacting subsequent cigarette production. Therefore, in existing technology, once a cigarette becomes skewed, the operator must straighten it to ensure it fits properly into the packaging box. This requires stopping the machine and manually opening the cigarette storage area or conveyor channel to straighten the skewed cigarettes one by one before restarting the equipment. However, manually straightening cigarettes not only increases the operator's workload but also reduces production efficiency, significantly lowering the reliability of the packaging machine and the quality of the packaged product.

[0004] Therefore, there is an urgent need for a cigarette-snatching mechanism that can straighten tilted cigarettes without manual intervention, in order to improve production efficiency and product quality, and reduce the workload of operators. Utility Model Content

This vibration corrects any misaligned cigarettes, ensuring they are neatly arranged before being placed. This facilitates the smooth entry of cigarettes into the subsequent cigarette channel, preventing breakage or deformation caused by squeezing or collision during packaging. This ensures that more cigarettes can enter the packaging box stably and intact, completing the subsequent packaging process.

Detailed Implementation

[0031] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0032] Example 1

[0033] like Figures 1-3As shown in this embodiment, a tobacco storage chamber for a packaging machine in tobacco processing equipment includes a storage chamber body 1 and two smoke-beating plates 2 that are opposite to each other and hinged to the front side of the storage chamber body 1. The hinge axis between the smoke-beating plates 2 and the storage chamber body 1 is vertical, and a smoke-beating mechanism 3 is also included. The storage chamber body 1 has an inverted Y-shaped flue, and the smoke-beating plates 2 are shaped to conform to the Y-shaped flue, meaning the two smoke-beating plates 2 can completely cover the Y-shaped flue. When cigarettes are conveyed from the cigarette machine to the Y-shaped flue in the packaging machine's tobacco storage chamber, they are all horizontally positioned, with the filter end of the cigarette facing the smoke-beating plates 2. It should be noted that the smoke-beating plates 2 are located at the front, and the storage chamber body 1 is located at the rear, meaning the smoke-beating mechanism 3 is located at the rear. Specifically, the smoke-beating mechanism 3 includes a drive mechanism 31, a swing mechanism 32, a linkage mechanism 33, and a push-pull mechanism 34 that are hinged in sequence. That is, the drive end of the drive mechanism 31 is hinged to one end of the swing mechanism 32, the other end of the swing mechanism 32 is hinged to one end of the linkage mechanism 33, the other end of the linkage mechanism 33 is hinged to one end of the push-pull mechanism 34, the drive mechanism 31, the swing mechanism 32, and the linkage mechanism 33 are located on the rear side of the smoke storage body 1, and the push-pull mechanism 34 passes through the smoke storage body 1 and is hinged to the two smoke-beating plates 2 respectively. The driving end of the driving mechanism 31 can drive the swing mechanism 32 to swing back and forth horizontally, so as to drive the push-pull mechanism 34 to move back and forth through the linkage mechanism 33. This causes the push-pull mechanism 34 to simultaneously drive the two tobacco-tapping plates 2 to tap the filter ends of the cigarettes in the cigarette storage body 1, that is, to vibrate the cigarettes. This promptly adjusts the crooked cigarettes to the correct posture, so that the cigarettes are neatly arranged by the tapping of the tobacco-tapping plates 2 before being arranged. This facilitates the smooth entry of the cigarettes into the subsequent cigarette channel and avoids the problem of breakage and deformation caused by the squeezing and collision of the cigarettes in the subsequent packaging process due to crookedness. This ensures that more cigarettes can enter the packaging box stably and intact to complete the subsequent packaging work. Moreover, the drive mechanism 31 can always drive the swing mechanism 32, the linkage mechanism 33 and the push-pull mechanism 34 to reciprocate, so that the patting plate 2 can always pat the cigarettes, so that the cigarettes can always be kept in order. This avoids the tedious process of manually stopping the machine repeatedly to straighten the cigarettes in the prior art, significantly reducing the labor intensity of the operators, while also improving the production efficiency and qualification rate of the products.

[0034] Furthermore, such as Figure 3 and Figure 4As shown, the swing mechanism 32 includes a horizontally arranged swing arm 321 and a pull rod 322, a vertically arranged rotating shaft 323 and a fixed shaft 324. One end of the swing arm 321 is hinged to the frame via the fixed shaft 324, which forms a stable pivot point to ensure that the swing arm 321 does not deviate when swinging around the axis of the fixed shaft 324. The other end of the swing arm 321 is hinged to one end of the pull rod 322 via the rotating shaft 323, and the other end of the pull rod 322 is hinged to one end of the linkage mechanism 33. The bottom of the rotating shaft 323 is rotatably connected to the driving end of the driving mechanism 31, so that the driving end of the driving mechanism 31 can drive the rotating shaft 323 to move back and forth horizontally around the axis of the fixed shaft 324, thereby driving the swing arm 321 to swing back and forth horizontally around the axis of the fixed shaft 324. This ensures that the driving mechanism 31 can smoothly transmit the swing of the swing arm 321 and the pull rod 322 to the linkage mechanism 33, which in turn drives the push-pull mechanism 34 and the cigarette-beating plate 2, so that the cigarette-beating plate 2 beats the cigarette, ensuring that the beating force, frequency and amplitude of the cigarette-beating plate 2 on the cigarette always remain uniform and stable. Preferably, the swing range of the swing arm 321 is between 12mm and 25mm, corresponding to the rotation angle of the slapping plate 2 around the hinge axis with the tobacco storage body 1 between 0° and 5°. That is, the slapping plate 2 can completely close the flue or open a gap of 7mm-15mm relative to the flue. In other words, when the push-pull mechanism 34 pushes the slapping plate 2, the maximum angle between the slapping plate 2 and the tobacco storage body 1 is 5°, and the slapping plate 2 opens a gap of 7mm-15mm relative to the flue. When the slapping plate 2 is pulled, it can return to its initial position, that is, the slapping plate 2 is in contact with the tobacco storage body 1 at 0°. This allows the two slapping plates 2 to repeatedly switch between a slightly open state and a closed state to slap the cigarettes in the flue neatly. In order to prevent the cigarettes from falling out of the flue, the swing range of the swing arm 321 is set to be small, so as to prevent the slapping plate 2 from completely opening the flue or opening a large gap in the flue, which would cause the cigarettes to fall. This achieves the effect of slapping only the cigarettes.

[0035] The pull rod 322 consists of a male and female pair of fisheye bearings, and its length can be adjusted as needed, i.e., by turning the male or female fisheye bearing, the length of the pull rod 322 can be changed.

[0036] Furthermore, such as Figure 1 , Figure 3 and Figure 6As shown, the smoke-dispelling mechanism 3 also includes a support base 4. The support base 4 is fixedly installed on the rear side wall of the smoke storage body 1. The middle part of the linkage mechanism 33 is located inside the support base 4 and is hinged to the support base 4 to provide a swing fulcrum for the linkage mechanism 33, so as to provide stable support for the movement of the linkage mechanism 33. When the drive mechanism 31 drives the linkage mechanism 33 to reciprocate through the swing mechanism 32, the middle part of the linkage mechanism 33 can effectively limit the offset of the linkage mechanism 33 by relying on the swing fulcrum formed by the support base 4, avoiding the shaking or positional displacement caused by the long length of the linkage mechanism 33 and uneven force.

[0037] Furthermore, such as Figure 1 , Figure 3 and Figure 5 As shown, the linkage mechanism 33 includes a first link 331, a second link 332, and a hinge plate 333. The hinge plate 333 is located between the first link 331 and the second link 332. Both ends of the hinge plate 333 are fixedly connected to the opposite ends of the first link 331 and the second link 332, respectively. The other end of the first link 331 is hinged to the end of the pull rod 322 away from the rotating shaft 323, and the other end of the second link 332 is hinged to the end of the push-pull mechanism 34 away from the smoke-beating plate 2. The hinge plate 333 is placed inside the support base 4 and hinged to the support base 4 via a vertically arranged rotating shaft. This allows the axis of the hinge plate 333 to serve as the rotation center of the linkage mechanism 33. When the swing mechanism 32 swings due to the drive mechanism 31, the first connecting rod 331 is pulled along with the pull rod 322 through its hinge to the pull rod 322. This causes the second connecting rod 332 to swing simultaneously through the hinge plate 333 in the opposite direction to the first connecting rod 331. This allows the linkage mechanism 33 to swing back and forth around the axis of the rotating shaft, thereby driving the two tobacco-beating plates 2 to repeatedly beat the cigarette. The rotating shaft can be a bolt, pin, or other similar component, serving only as an axle to hinge the hinge plate 333 to the support base 4. Furthermore, multiple flat spring pads are fitted on the outer wall of the rotating shaft to prevent hard collisions between the rotating shaft and the support base 4, and between the hinge plate 333 and the support base 4, reducing component wear. The hinge plate 333 is equipped with a fisheye spherical bearing to reduce the rotational friction between the hinge plate 333 and the rotating shaft and improve smoothness.

[0038] Furthermore, such as Figure 1 and Figure 5As shown, the linkage mechanism 33 also includes a horizontally arranged Y-shaped fork 334. The Y-shaped fork 334 includes an internally threaded sleeve 3341 and a vertically arranged U-shaped hinge seat 3342. One end of the internally threaded sleeve 3341 is fixedly connected to the back side wall of the hinge seat 3342, and the other end is screwed to the end of the first connecting rod 331 away from the hinge plate 333. This enables the Y-shaped fork 334 to be detachably connected, making it easy to replace when damaged. The end of the pull rod 322 away from the pivot 323 is placed inside the hinge seat 3342 and hinged to the hinge seat 3342. A nut 335 is screwed onto the end of the first connecting rod 331 away from the hinge plate 333. The nut 335 can engage with the end of the internal threaded sleeve 3341 away from the hinge seat 3342, which is used to limit the position of the Y-shaped fork 334 screwed onto the first connecting rod 331, thereby limiting the length of the first connecting rod 331 and the Y-shaped fork 334. At the same time, it can also change the length between the first connecting rod 331 and the Y-shaped fork 334. That is, by screwing the Y-shaped fork 334, the internal threaded sleeve 3341 can move towards or away from the hinge plate 333, thereby changing the length of the first connecting rod 331 and the Y-shaped fork 334, that is, changing the swing radius of the first connecting rod 331, so as to adapt to the beating of cigarettes in the cigarette compartment of different packaging machines, improving practicality and applicability. Nut 335 also secures the Y-shaped fork head 334. Once the length of the first connecting rod 331 is determined, nut 335 is fixedly screwed onto a position on the first connecting rod 331, effectively acting as a fixing nut 335. Tightening the Y-shaped fork head 334 ensures a tight fit between the internal threaded sleeve 3341 and nut 335, preventing further tightening of the internal threaded sleeve 3341 and preventing relative movement between them. This secures the Y-shaped fork head 334 to its current position, effectively resisting vibrations and impacts during the packaging machine's operation and preventing loosening of the screw connection due to vibration.

[0039] Furthermore, such as Figure 1 , Figure 3 and Figure 7As shown, the push-pull mechanism 34 includes a mounting base 341, two push rods 342, and two universal joints 343. The mounting base 341 is located outside the smoke chamber body 1, and the side of the mounting base 341 away from the smoke chamber body 1 is hinged to the end of the second connecting rod 332 away from the hinge plate 333. One end of each of the two push rods 342 passes through the mounting base 341 and is fixedly connected to the mounting base 341, while the other ends of each push rod pass through the rear side wall of the smoke chamber body 1 and are respectively connected to the rear side wall of the two smoke-beating plates 2 through the universal joints 343. When the second connecting rod 332 swings around the axis of rotation, it drives the mounting base 341 to move back and forth. Simultaneously, the two push rods 342 move synchronously with the mounting base 341 at the same speed and stroke. This, in turn, drives the two slapping plates 2 via the universal joint 343 to slap the cigarettes inside the cigarette storage body 1. This prevents uneven slapping of the cigarettes due to asynchronous movement speed and stroke of the two slapping plates 2, ensuring that all tilted cigarettes in the cigarette storage are straightened. This further improves the neatness of the cigarette arrangement and reduces the risk of cigarette breakage and deformation caused by inconsistent slapping. Furthermore, the universal joint 343 enables multi-angle power transmission to adapt to changes in the angular position of the slapping plates 2.

[0040] Furthermore, such as Figure 7 As shown, a magnet 344 is fixedly connected to the end of the universal joint 343 away from the push rod 342, and the universal joint 343 is magnetically connected to the corresponding smoke-beating plate 2 through the magnet 344. This enables the universal joint 343 and the smoke-beating plate 2 to be quickly disassembled and assembled, improving the positioning and disassembly efficiency of the push-pull mechanism 34 and the smoke-beating plate 2, and reducing the assembly difficulty.

[0041] In addition, it should be noted that since the tobacco storage needs to be inspected and repaired later, the flue of the tobacco blasting plate 2 needs to be opened. The tobacco blasting mechanism 3 can only be set on the rear side of the tobacco blasting plate 2. Moreover, the universal joint 343 is magnetically connected to the tobacco blasting plate 2 through the magnet 344, so that the flue can be opened without affecting the tobacco blasting mechanism 3 from blasting the tobacco sticks, so as to facilitate subsequent maintenance work and improve adaptability.

[0042] Furthermore, such as Figure 7As shown, the push-pull mechanism 34 also includes a push rod sleeve 345. The push rod sleeve 345 is hinged to the side wall of the mounting base 341 away from the smoke chamber body 1. The end of the second connecting rod 332 away from the hinge plate 333 is inserted into the push rod sleeve 345, so that the second connecting rod 332 can drive the mounting base 341, the two push rods 342, and the two universal joints 343 to move back and forth simultaneously. By setting the push rod sleeve 345, indirect contact can be achieved between the second connecting rod 332 and the mounting base 341, effectively avoiding direct friction between the second connecting rod 332 and the mounting base 341. Moreover, the push rod sleeve 345 is hinged to the mounting base 341, which allows the push rod sleeve 345 to flexibly adjust its angle when the second connecting rod 332 drives the push rod sleeve 345 to move, ensuring that the arc-shaped movement of the second connecting rod 332 can be smoothly and easily converted into the linear movement of the mounting base 341, avoiding problems such as mechanism jamming and accelerated component wear caused by trajectory differences.

[0043] Furthermore, such as Figure 7 As shown, a connecting rod sleeve 346 is fitted inside the push rod sleeve 345. The axes of the push rod sleeve 345 and the connecting rod sleeve 346 are aligned, and the end of the second connecting rod 332 away from the hinge plate 333 is inserted into the connecting rod sleeve 346, which allows the push rod sleeve 345 and the second connecting rod 332 to avoid direct contact. The connecting rod sleeve 346, as an intermediate component for indirect contact between the push rod sleeve 345 and the second connecting rod 332, prevents friction between the second connecting rod 332 and the push rod sleeve 345, thus preventing relative wear on the connecting rod sleeve 346. However, because the connecting rod sleeve 346 is made of relatively soft material and has a low cost, even if wear occurs, only the connecting rod sleeve 346 needs to be replaced; the second connecting rod 332 or the push rod sleeve 345 does not need to be replaced. This effectively protects the second connecting rod 332 and the push rod sleeve 345, extending their service life.

[0044] Furthermore, such as Figure 1 As shown, two guide seats 5 are also installed on the rear side wall of the tobacco storage body 1. The two guide seats 5 correspond one-to-one with the two push rods 342, and the two push rods 342 are respectively inserted through the guide seats 5, so that the guide seats 5 provide guidance for the push rods 342, ensuring that the two push rods 342 always move stably in a straight line, and then drive the two tobacco-beating plates 2 to beat the cigarettes in the tobacco storage body 1 through the universal joint 343, thereby improving the production efficiency and qualification rate of cigarette packaging.

[0045] Furthermore, such as Figures 1-3As shown, the drive mechanism 31 includes a drive motor 311, a Geneva wheel 312, a bracket 313, and a moving rod 314. The output end of the drive motor 311, i.e., the drive shaft, is connected to one end of the Geneva wheel 312. Both ends of the Geneva wheel 312 are horizontally and rotatably mounted on the bracket 313. The Geneva wheel 312 has grooves, which is existing technology. The moving rod 314 is T-shaped. The bottom of the vertical section of the moving rod 314 is placed in the groove, while the horizontal section passes through the bracket 313 and is parallel to the axis of the Geneva wheel 312. The end of the horizontal section facing the swing arm 321 is rotatably connected to the bottom of the rotating shaft 323. Starting the drive motor 311 enables it to rotate the grooved wheel 312, allowing the bottom of the vertical section of the moving rod 314 to move along the groove. This, in turn, causes the horizontal section to move back and forth along its own axis, which in turn causes the swing rod 321 to swing back and forth around the axis of the fixed shaft 324, and the pull rod 322 to swing back and forth. This, in turn, causes the linkage mechanism 33 to swing back and forth, thereby completing the action of pushing open and pulling back the two cigarette-beating plates 2 by the two push rods 342 to beat the cigarette.

[0046] It should be noted that the drive mechanism 31 in this embodiment can also be other mechanisms that can drive the swing arm 321 to swing back and forth. The specific structure of the drive mechanism 31 is not limited here.

[0047] Based on the above structure, the working principle of a tobacco storage compartment for a packaging machine in tobacco processing equipment according to this embodiment is as follows:

[0048] like Figure 1 and Figure 3As shown, the drive shaft of the drive motor 311 drives the grooved wheel 312 to rotate, causing the bottom of the vertical section of the moving rod 314 to move along the groove of the grooved wheel 312, causing the horizontal section of the moving rod 314 to move away from the tobacco storage body 1. This causes the swing rod 321 to swing around the axis of the fixed shaft 324 away from the tobacco storage body 1. At the same time, the swing rod 321 drives the pull rod 322 to swing around the axis of the rotating shaft 323 through the rotating shaft 323, causing the pull rod 322 to swing through the Y-shaped fork 33. 4. The first connecting rod 331 is driven to swing away from the smoke chamber body 1. At this time, the hinge plate 333 rotates around the axis of the rotating shaft, causing the second connecting rod 332 to swing towards the smoke chamber body 1. The second connecting rod 332 drives the mounting base 341 to move towards the smoke chamber body 1 through the push rod sleeve 345. This allows the two push rods 342 to push open the two smoke-beating plates 2 through the two universal joints 343, thereby opening the flue and keeping the flue in a slightly open state. The drive motor 311 continuously drives the grooved wheel 312 to rotate, causing the moving rod 314 to move towards the tobacco storage body 1. This causes the swing rod 321 to swing around the axis of the fixed shaft 324 towards the tobacco storage body 1. At the same time, the swing rod 321 drives the pull rod 322 to swing around the axis of the rotating shaft 323 via the rotating shaft 323. This causes the pull rod 322 to drive the first connecting rod 331 to swing towards the tobacco storage body 1 via the Y-shaped fork head 334. At this time, the hinge plate 333 rotates around the axis of the rotating shaft, causing the second connecting rod 332 to swing away from the tobacco storage body 1. This causes the second connecting rod 332 to drive the mounting base 341 to move away from the tobacco storage body 1 via the push rod sleeve 345. This allows the two push rods 342 to pull the two tobacco-beating plates 2 through the two universal joints 343, thereby closing the flue and putting the flue in a closed state. This causes the filter ends of the cigarettes in the flue to be beaten, so that the cigarettes can be arranged neatly.

[0049] As described above, the cigarette-tapping mechanism 3 taps the filter end of the cigarette once. Driven by the drive motor 311 and through the continuous action of the swing mechanism 32, the linkage mechanism 33 and the push-pull mechanism 34, the two push rods 342 repeatedly push open and pull back the cigarette-tapping plate 2, so that the two cigarette-tapping plates 2 can repeatedly tap the filter end of the cigarette, so that the cigarettes in the flue can be arranged neatly.
