Description

Technical Field

[0001] The present invention relates to the technical field of cigarette manufacturing, in particular to a conveying stabilizing mechanism for a cigarette mold box conveying device. Background Art

[0002] Currently, our Yellow Crane Tower 1916 series of 15-year-old cigarettes are arranged in a double-ten arrangement, with the inner packaging using a self-developed, reusable, aroma- and moisture-retaining wrapping sheet. The inner wrapping sheet is first packaged, followed by the outer box. Because this product is an extra-long, extra-wide, and irregularly shaped cigarette, a specialized unit is required to secure, convey, and package the double-ten arrangement. The entire packaging process takes place within the cigarette mold box conveyor.

[0003] The utility model patent with authorization announcement number CN216660446U discloses a cigarette mold box conveying and cigarette pushing device for slim-line run-proof cigarette packs, including: a mold box conveyor belt for horizontally conveying the mold boxes, and a cigarette magazine, a detection unit and a pushing unit arranged in sequence along the conveying direction of the mold boxes; wherein, the cigarette magazine is used to load cigarettes into the conveyed mold boxes, the detection unit is used to detect cigarette damage on the mold boxes containing cigarettes, and the pushing unit is used to push cigarettes on the mold boxes whose detection results indicate that the cigarettes are qualified so as to load the cigarettes into the run-proof cigarette packs.

[0004] In the above-mentioned cigarette mold box conveying device, the cigarette mold boxes are arranged at intervals on the mold box conveyor belt to ensure that the packaging mechanism can carry out the automated packaging of cigarettes in sequence. Specifically, every time the cigarette mold box is driven by the mold box conveyor belt to step into a workstation, the packaging mechanism arranged in the width direction of the mold box conveyor belt folds the inner packaging box sheet once. When the inner packaging box sheet is folded into the preset "U" shape, the cigarette mold box enters the next process along the mold box conveyor belt.

[0005] However, during the actual conveying process, because the stacking of cigarettes in a double-ten arrangement is heavier than that of conventional cigarettes, the cigarette molds and cigarettes are more likely to experience relative displacement due to inertia during movement. Specifically, during packaging, the cigarette molds move in sequence along the mold conveyor. During this movement, friction or gaps easily form between the mold guards on both sides of the cigarette molds and the cigarettes, causing relative displacement of the upper and lower layers of the double-ten arrangement. This can result in packaging defects such as uneven cigarette arrangement, deformed packaging, and cigarette damage. Summary of the Invention

[0006] In order to solve the problems existing in the prior art, the present invention provides a conveying stabilization mechanism for a cigarette mold box conveying device, which can prevent the internal cigarettes of the cigarette mold box from shifting during the conveying process, provide a stable conveying environment, and avoid obtaining cigarette products with quality defects.

[0014] Furthermore, the conveying stabilization mechanism for the cigarette mold box conveying device provided by the present invention may also have the following feature: a groove for reducing the load is provided on the limiting member.

[0015] Furthermore, the conveying stabilization mechanism for the cigarette mold box conveying device provided by the present invention may also have the following characteristics: it also includes a cigarette protection piece for keeping the cigarettes in the cigarette mold box arranged in order to enter the next process, and the cigarette protection piece is arranged in the exit area along the conveying direction of the synchronous belt and abuts against the upper wall of the cigarette mold box.

[0016] Furthermore, the conveying stabilization mechanism for the cigarette mold box conveying device provided by the present invention may also have the following characteristics: it includes two synchronous belts, and the two synchronous belts are respectively arranged above the two ends of the mold box conveying belt in the width direction.

[0017] The beneficial effects of the present invention are:

[0018] 1. In this application, by providing a synchronous belt that runs in the same direction as the mold box conveyor belt, the synchronous belt can drive multiple spaced-apart limiting members thereon to move synchronously with the cigarette mold boxes, with each limiting member being positioned between two cigarette mold boxes. This design of limiting positions in the conveying direction effectively stabilizes the position of the cigarette mold boxes during conveyance, reduces relative displacement between the cigarettes and the cigarette mold boxes due to inertial movement, and ensures that the upper and lower layers of the double-ten cigarettes arranged in the cigarette mold boxes are stable during packaging operations, thereby preventing packaging defects such as uneven cigarette arrangement, package deformation, and cigarette crushing.

Furthermore, a cigarette pressing member is provided above the cigarette pressing body. The cigarette pressing member abuts the cigarette pressing body to ensure the flatness of the cigarette pressing body. At the same time, the flattened cigarette pressing body applies pressure to the cigarette mold box it abuts below. This vertical positioning of the cigarette mold box, combined with the positioning member's positioning of the cigarette mold box in the conveying direction, can effectively stabilize the order of the double-ten cigarettes during packaging without displacement, thereby maintaining the packaging quality of the cigarette products.

[0020] 3. In this application, an additional bracket is designed to support and secure the entire timing belt, effectively ensuring the stability of the conveyor stabilization mechanism during operation and preventing unnecessary vibration and shaking. The coordination of the bracket's supporting and securing components ensures the conveyor stabilization mechanism maintains its stability on the cigarette mold boxes while preventing the presence of the conveyor stabilization mechanism from affecting the workpiece positioning and operation of the original mold box conveyor.

[0021] 4. In this application, a pulley adjustment member is provided to adjust the position of the synchronous pulleys, ensuring appropriate tension between the pulleys and the synchronous belt. Specifically, by adjusting the position of the screw in the strip groove, the synchronous pulley can be moved along the length of the synchronous belt, thereby changing the spacing between the two synchronous pulleys. This adjustable tension design ensures the precise and reliable fit between the synchronous belt and the mold box conveyor belt, thereby improving the stability of the conveyor stabilization mechanism.

[0022] 5. In this application, by designing a cigarette protection piece in the exit area that abuts against the upper wall of the cigarette mold box, it is ensured that after the packaging of the inner box sheet is completed, the cigarettes in the cigarette mold box can still be arranged in order and smoothly enter the next process, thereby further ensuring the quality of the cigarette products.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0033] like Figure 1 As shown, the cigarette mold box conveying device includes a cigarette mold box 1 for accommodating cigarettes and a mold box conveyor belt (not shown in the figure). The mold box conveyor belt is configured to convey the cigarette mold boxes 1 at intervals. Figure 1 The packaging mechanism is provided with a preset folding program. During the packaging operation, each time the cigarette mold box 1 is driven by the mold box conveyor belt to step into a station, the packaging mechanism folds the inner box sheet once. Specifically, Figure 1 and Figure 5 As shown, the mold box conveyor belt conveys from right to left (with Figure 1 Taking the direction shown as an example), the cigarette mold box 1 at the first position 101 has an inner packaging sheet that has completed the first fold 201. After the double-ten cigarettes are pushed into the inner packaging sheet that has completed the first fold 201 by a separately provided pushing mechanism, the cigarette mold box 1 at the first position 101 steps forward one station; when the cigarette mold box 1 steps to the second position 102, the packaging mechanism performs the second fold 202 on the inner packaging sheet; after the second fold 202 is completed, the mold box conveyor belt drives the cigarette mold box 1 to step to the third position 103, and the packaging mechanism performs the second fold 202 on the inner packaging sheet. Perform the third fold 203; after the third fold 203 is completed, the mold box conveyor belt drives the cigarette mold box 1 to step to the fourth position 104, and the packaging mechanism performs the fourth fold 204 on the inner packaging box sheet; after the fourth fold 204 is completed, the mold box conveyor belt drives the cigarette mold box 1 to step to the fifth position 105, and the packaging mechanism performs the fifth fold 205 on the inner packaging box sheet and completes this process. The final result is a "U"-shaped inner packaging box sheet that wraps the double-ten cigarettes. After that, the cigarette mold box 1 located at the fifth position 105 is conveyed to the next process by the mold box conveyor belt.

[0034] However, during the actual conveying process, because the stacking of cigarettes in a double-ten arrangement is heavier than in the same row of conventional cigarettes, the cigarette mold box 1 and the cigarettes are more likely to experience relative displacement due to inertia. Specifically, as the cigarette mold box 1 moves along the mold box conveyor, friction or gaps easily form between the mold box guards on both sides of the cigarette mold box 1 and the cigarettes, causing relative displacement of the upper and lower layers of the double-ten arrangement. This can result in packaging defects such as uneven cigarette arrangement, deformation of the packaging, and crushed cigarettes in the final cigarette product.

[0035] In order to solve the above problems, this utility model discloses a conveying stabilizing mechanism for a cigarette mold box conveying device, such as Figure 1-4 As shown, the conveying stabilization mechanism includes at least one synchronous belt 2, which is arranged above the mold box conveyor belt and runs in the same direction as the mold box conveyor belt. It also includes stoppers 3 for limiting the position of the cigarette mold box 1 in the conveying direction. The stoppers 3 are evenly spaced on the synchronous belt 2 and abut against the side walls of the cigarette mold box 1. The distance between two adjacent stoppers 3 is equal to the length of the cigarette mold box 1. During use, the synchronous belt 2 can drive the multiple stoppers 3 arranged at intervals thereon to move synchronously with the cigarette mold box 1. Because the stoppers 3 are clamped between two cigarette mold boxes 1, this design effectively ensures the position stability of the cigarette mold box 1 during conveyance, reduces the relative displacement between the cigarettes and the cigarette mold box 1 due to inertia, and thus ensures the position stability of the upper and lower layers of the double-ten cigarettes arranged in the cigarette mold box 1 during packaging, thereby ensuring the quality of the final cigarette product.

[0036] In some embodiments, the portion where the synchronous belt 2 abuts against the upper wall of the cigarette mold box 1 forms a cigarette pressing belt body 21. The cigarette pressing belt body 21 is set to limit the cigarette mold box 1 in the vertical direction to ensure that the cigarettes inside it can be arranged in sequence without displacement during the packaging operation.

[0037] As a further improvement to the above embodiment, the conveying stabilization mechanism further includes a cigarette pressing member 4, which is positioned above the cigarette pressing belt 21 and abuts against the cigarette pressing belt 21. During use, the cigarette pressing member 4 abuts against the cigarette pressing belt 21 to ensure the flatness of the cigarette pressing belt 21. Simultaneously, the flattened cigarette pressing belt 21 applies pressure to the cigarette mold box 1 abutting thereunder. This vertical positioning of the cigarette mold box 1, combined with the positioning of the cigarette mold box 1 in the conveying direction by the limiting member 3, effectively stabilizes the order of the 10-pack cigarettes during packaging and prevents displacement, thereby preventing packaging defects such as uneven cigarette arrangement, package deformation, and cigarette crushing. Furthermore, the height of the cigarette pressing member 4 relative to the conveying surface of the mold box conveyor is preferably adjustable, so that the cigarette pressing member 4 exerts an appropriate pressure during use, achieving the effect of not damaging the cigarettes while still vertically positioning the cigarette mold box 1.

[0038] The conveying stabilization mechanism also includes a synchronous pulley 5 for driving the synchronous belt 2 to rotate. A pulley shaft 6 is provided in the middle of the synchronous pulley 5 for supporting the synchronous pulley 5. Generally speaking, the pulley shaft 6 serves as the base for the installation of the synchronous pulley 5 and is used to ensure the position stability of the synchronous pulley 5 during the transmission process. It does not need to drive the synchronous pulley 5 to rotate. The movement of the synchronous pulley 5 is powered by an external power source, preferably an electric motor.

[0039] In some embodiments, since the original mold box conveyor belt is also provided with a packaging mechanism, and even a detection mechanism, a rejection mechanism and other components in its width direction, in order to ensure that the conveying stabilization mechanism provided by the present invention is stable and does not shake during operation, it is also necessary to ensure that its existence does not affect the workpiece position or operation of the original mold box conveying device. Figure 2 As shown, the preferred conveying stabilization mechanism also includes a bracket 7 for supporting the synchronous belt 2, and the bracket 7 includes a support member 71 and a fixing member 72; the support member 71 is connected to the pulley shaft 6; the fixing member 72 is fixed to the ground or the fixed structure of the cigarette mold box conveying device, and is connected to the support member 71.

[0040] As a further improvement to the above embodiment, the bracket 7 further includes a connecting structure 73, through which the support member 71 and the fixing member 72 are connected; the connecting structure 73 includes a connecting member 731, a first connecting portion 732 for connecting the connecting member 731 and the fixing member 72, and a second connecting portion 733 for connecting the connecting member 731 and the support member 71. The first connecting portion 732 and the second connecting portion 733 are not necessarily selected. In this embodiment, the first connecting portion 732 is preferably a screw, and the screw is inserted through first threaded holes arranged oppositely on the fixing member 72 and the connecting member 731. The second connecting portion 733 is preferably a threaded column of a certain length, which is inserted through second threaded holes arranged oppositely on the support member 71 and the connecting member 731 and is fixed by a nut. This design can further ensure that the presence of the bracket 7 does not affect the operation of other workpieces.

[0041] In some specific embodiments, Figure 3 As shown, the smoke suppressor 4 includes a smoke suppressor connecting portion 41 and a smoke suppressor portion 42. The smoke suppressor portion 42 abuts the smoke suppressor belt body 21, while the smoke suppressor connecting portion 41 is connected to the support member 71. To allow for vertical adjustment of the smoke suppressor 4, the smoke suppressor connecting portion 41 preferably defines a first strip groove 411, and the support member 71 defines a corresponding third threaded hole. Screws are inserted through the first strip groove 411 and the third threaded hole to secure the smoke suppressor 4. During use, by adjusting the position of the screw in the first strip groove 411, the height of the smoke suppressor 42 relative to the mold box conveyor belt can be changed, thereby varying the smoke suppressor force.

[0042] In some embodiments, as Figure 4 As shown, the conveyor stabilization mechanism also includes a pulley adjustment member 8, which includes a pulley adjustment portion 81 and a pulley connection portion 82. The pulley connection portion 82 is connected to the pulley shaft 6. The pulley adjustment portion 81 is connected to the support member 71 via an adjustment structure. The adjustment structure includes a second strip groove 811 provided on the pulley adjustment portion 81, a fourth threaded hole provided on the support member 71, and a screw that passes through the second strip groove 811 and the fourth threaded hole in sequence. During use, the pulley adjustment member 8 is used to adjust the position of the synchronous pulley 5 to ensure appropriate tension between the synchronous pulley 5 and the synchronous belt 2. Specifically, by adjusting the position of the screw in the second strip groove 811, the synchronous pulley 5 can be moved along the length of the synchronous belt 2, thereby changing the spacing between the two synchronous pulleys 5 of the synchronous belt 2. This adjustable tension design ensures the precision and reliability of the fit between the synchronous belt 2 and the mold box conveyor belt, thereby improving the stability of the conveyor stabilization mechanism.

[0043] In some embodiments, as Figure 1 As shown, the stopper 3 is provided with a groove 31 for reducing the load. Furthermore, compared to an integral stopper 3, the groove 31 not only reduces the load but also reduces stress concentration and vibration caused by the integral stopper 3 when the stopper 3 passes through the turning area of ​​the synchronous belt 2, providing a certain buffering effect and extending the service life of the synchronous belt 2 and the stopper 3.

[0044] In some embodiments, the conveying stabilization mechanism further includes a cigarette guard 9 for maintaining the order of cigarettes within the cigarette mold box 1 for entry into the next process. The cigarette guard 9 is located at the exit area along the conveying direction of the timing belt 2 and abuts against the upper wall of the cigarette mold box 1. When in use, the cigarette guard 9 ensures that after the inner wrapper sheet is packaged, the cigarettes within the cigarette mold box 1 that have reached the fifth position 105 remain in order and smoothly enter the next process, further ensuring the quality of the cigarette products.

[0045] In some embodiments, the conveying stabilization mechanism includes two synchronous belts 2, which are respectively arranged above the two ends of the mold box conveyor belt in the width direction to ensure that the front and rear ends of the cigarette mold box 1 (with Figure 1 direction shown as an example) to maintain synchronous movement.
