Abstract
Description
Technical Field
[0001] This utility model relates to the field of cigarette packaging machine technology, and in particular to a conveying device and a cigarette packaging machine. Background Technology
[0002] The efficient and stable operation of cigarette packaging machines is crucial for ensuring product quality and production efficiency. As a core component of the packaging machine, the stability of the label paper conveying process directly affects the precision of subsequent packaging and the overall production rhythm. The label paper (box sheet) must maintain a precise position and posture during conveying to ensure accurate coordination with subsequent receiving rollers, forming devices, and other components. This places extremely high demands on the pressure control used to constrain and stabilize the box sheet during conveying.
[0003] Currently, at step 15 of the label paper conveying section of the X2 packaging machine, there are usually two elastic elements. Their core function is to provide continuous and appropriate pressure to the box sheets, ensuring that the boxes do not shift or shake during conveying due to external forces or changes in machine speed, thus maintaining conveying stability. However, the pressure adjustment of the existing elastic elements mainly relies on bending the springs, that is, manually bending the springs to change the pressure of the elastic elements on the box sheets. This method depends entirely on the operator's experience and judgment, and cannot achieve precise control and stable pressure maintenance. Utility Model Content
[0004] The purpose of this utility model is to provide a conveying device and a cigarette packaging machine to solve the problems of inaccurate control and unstable box conveying caused by the existing elastic parts relying on bending springs to adjust pressure, improve the stability and accuracy of box conveying, ensure product quality, and increase the production efficiency of cigarette packaging machines.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A conveying device for conveying box pieces, the conveying device comprising:
[0007] The conveying platform, two baffles, and a conveying assembly are provided. The two baffles are located on both sides of the conveying platform, and the conveying assembly is located between the two baffles. The conveying assembly conveys the box piece along a first direction.
[0008] The elastic pressing component includes a mounting base and an elastic element. The mounting base is fixedly connected to the baffle, one end of the elastic element is connected to the mounting base, and the other end of the elastic element can press the box against the conveying platform.
[0009] The adjustment assembly includes a fixed plate and a threaded rod. The fixed plate is fixedly connected to the mounting base.

The fixing part is connected to the mounting base, the pressing part can press against the box piece, the connecting part forms a preset angle with the first direction, and the threaded rod abuts against the connecting part.
[0011] As an alternative to the conveying device, the conveying device also includes fasteners that pass through the fixing plate and the fixing part in sequence and are threadedly connected to the mounting base.
[0012] As an alternative to the conveying device, the adjustment assembly also includes an operating element fixedly connected to one end of the threaded rod opposite to the connecting portion.
[0013] As an alternative to the conveying device, the conveying device includes two symmetrically arranged elastic pressing components and two adjusting components. The two elastic pressing components are respectively connected to the two baffles, and each adjusting component cooperates with one elastic pressing component.
[0014] As an alternative to the conveying device, the conveying device also includes a paper receiving roller, the two ends of which are rotatably connected to the two baffles respectively, and the paper receiving roller rolls against the box sheet.
[0015] As an alternative to the conveying device, the conveying device also includes a brush assembly located between the paper receiving roller and the adjusting assembly.

The drive member pushes the box piece to move along the first direction through the pusher plate.
[0017] As an alternative to the conveying device, the conveying assembly further includes a lifting member, which is fixedly installed. The output end of the lifting member is connected to the driving member. The output end of the lifting member can drive the driving member and the push plate to reciprocate along a second direction, which is perpendicular to the first direction.
[0018] A cigarette packaging machine includes a feeding device, a forming device, and the aforementioned conveying device, wherein the conveying device is located between the feeding device and the forming device and is used to convey the carton sheet from the feeding device to the forming device.
[0019] Beneficial effects:
[0020] This invention provides a conveying device and a cigarette packaging machine. The conveying device achieves precise control of the conveying pressure of the packing sheets through a cooperative structure of an elastic pressing component and an adjusting component. When the threaded rod is rotated, it can move axially via a threaded connection with the threaded hole of the fixed plate, thereby generating varying degrees of resistance on the side of the elastic element away from the packing sheet, thus changing the pressure exerted by the elastic element on the packing sheet. This allows the pressure of the elastic element on the packing sheet to be precisely controlled according to actual conveying needs, avoiding problems such as excessive pressure causing obstruction of packing sheet conveying and platform blockage, or insufficient pressure causing packing sheet offset due to inertia and misalignment with the receiving roller. Therefore, when the packing sheet moves along the first direction driven by the conveying component, it maintains a stable posture and accurate position under the limiting action of the two baffles and the stable pressing action of the elastic element, ensuring the stability of the conveying process. This also reduces production interruptions caused by conveying failures, ensuring overall product quality consistency and improving the production efficiency of the cigarette packaging machine.

[0033] This embodiment provides a conveying device and a cigarette packaging machine. The cigarette packaging machine includes a feeding device (not shown), a forming device (not shown), and a conveying device. The conveying device is located between the feeding device and the forming device and is used to transport the box sheet 100 from the feeding device to the forming device. The feeding device is responsible for preparing the box sheet 100 and transferring it to the conveying device. The conveying device stably and accurately transports the box sheet 100 to the forming device along a first direction. This orderly connection ensures the continuity of the box sheet 100 from its raw material state to its entry into the forming stage, avoiding production interruptions caused by the lack of coordination between devices.
[0034] like Figures 1-2As shown, the conveying device is used to convey the box piece 100. The conveying device includes a conveying platform 1, two baffles 2, a conveying assembly, an elastic pressing assembly 4, and an adjusting assembly 5. The two baffles 2 are located on both sides of the conveying platform 1, and the conveying assembly is located between the two baffles 2. The conveying assembly conveys the box piece 100 along a first direction. The elastic pressing assembly 4 includes a mounting base 41 and an elastic element 42. The mounting base 41 is fixedly connected to the baffle 2. One end of the elastic element 42 is connected to the mounting base 41, and the other end of the elastic element 42 can press the box piece 100 against the conveying platform 1. The adjusting assembly 5 includes a fixing plate 51 and a threaded rod 52. The fixing plate 51 is fixedly connected to the mounting base 41. The fixing plate 51 is provided with a threaded hole, and the threaded rod 52 is threadedly connected to the threaded hole. The threaded rod 52 abuts against the side of the elastic element 42 away from the box piece 100.
[0035] This conveying device achieves precise control of the conveying pressure of the box sheet 100 through the cooperative structure of the elastic pressing component 4 and the adjusting component 5. When the threaded rod 52 is rotated, it can move axially through the threaded connection with the threaded hole of the fixed plate 51, thereby generating different degrees of resistance force on the side of the elastic element 42 away from the box sheet 100, thus changing the pressure of the elastic element 42 on the box sheet 100. This allows the pressure of the elastic element 42 on the box sheet 100 to be precisely controlled according to the actual conveying requirements, avoiding problems such as excessive pressure causing obstruction of the box sheet 100 conveying and platform blockage, or insufficient pressure causing the box sheet 100 to shift due to inertia and misalignment with the receiving roller 7. Therefore, when the box piece 100 moves along the first direction under the drive of the conveying assembly, it can always maintain a stable posture and accurate position under the limiting action of the two baffles 2 and the stable pressing action of the elastic element 42, ensuring the stability of the conveying process, reducing production interruptions caused by conveying failures, ensuring the consistency of product quality as a whole, and improving the production efficiency of the cigarette packaging machine.
[0036] In this embodiment, the threaded rod 52 and the threaded hole adopt fine-pitch threads. Due to their small pitch and high number of threads, the accuracy of pressure adjustment can be significantly improved. When the operator rotates the threaded rod 52 via the operating component 53, the fine-pitch threads make the axial movement of the threaded rod 52 more subtle. With each rotation, the change in the resistance force of the threaded rod 52 against the elastic element 42 is more gradual, facilitating fine-tuning of the pressure on the elastic element 42. Simultaneously, the fine-pitch threads have better self-locking performance. After adjustment, the threaded rod 52 is less prone to loosening due to external forces such as equipment vibration, maintaining the preset pressure value for a long time and ensuring stable resistance force of the elastic element 42 against the disc 100.
[0037] In this embodiment, the fixing plate 51 is a steel plate-shaped component. Utilizing the high strength and rigidity of steel, it provides a stable supporting foundation for the mating of the threaded rod 52 and the threaded hole. Simultaneously, the plate-shaped structure increases the connection area between the fixing plate 51 and the mounting base 41. Combined with the fixing effect of the fasteners 6, this further enhances the firmness of the connection and reduces the overall structural sway.
[0038] like Figure 1 As shown, the elastic element 42 includes a fixing part 421, a connecting part 422, and a pressing part 423 connected in sequence. The fixing part 421 is connected to the mounting base 41, the pressing part 423 can press against the box piece 100, the connecting part 422 forms a preset angle with the first direction, and the threaded rod 52 abuts against the connecting part 422. The elastic element 42 forms a specific structure through the sequential connection of the fixing part 421, the connecting part 422, and the pressing part 423. The fixing part 421 is firmly connected to the mounting base 41 to provide support for the whole, the pressing part 423 directly contacts the box piece 100 to realize pressure transmission, and the design of the connecting part 422 forming a preset angle with the first direction provides a reasonable lever arm and force angle for adjusting the contact of the threaded rod 52. When the threaded rod 52 abuts against and is adjusted with the connecting part 422, the axial force applied by the threaded rod 52 can be more efficiently converted into pressure on the box piece 100 by the pressing part 423 due to the tilt angle of the connecting part 422. Furthermore, the force transmission path is stable, and the deformation of the connecting part 422 can be precisely controlled by rotating the threaded rod 52, thereby accurately adjusting the pressure of the pressing part 423 on the box piece 100. This structure makes the pressure adjustment of the elastic element 42 on the box piece 100 more linear, the operation more intuitive, and avoids the problem of unstable force transmission during traditional bending spring adjustment. Meanwhile, under the elastic support of the connecting part 422, the pressing part 423 can always maintain reliable contact with the box piece 100. With the conveying force of the conveying component along the first direction and the limiting effect of the baffle 2, the box piece 100 will not be obstructed or stopped on the conveying platform 1 due to excessive pressure, nor will it deviate or shake due to insufficient pressure. This ensures the stability and positional accuracy of the conveying process, lays the foundation for the precise coordination of subsequent processes, and further improves the reliability and production efficiency of the overall conveying device.
[0039] In this embodiment, the connecting portion 422 forms a preset angle with the first direction, creating smooth guiding conditions for the box piece 100 to enter the pressing portion 423 along the first direction. When the box piece 100 moves along the first direction under the drive of the conveying assembly, due to the inclined setting of the connecting portion 422, a gradually narrowing entrance area is formed at its connection with the pressing portion 423. Before the front end of the box piece 100 contacts the pressing portion 423, it will first form a smooth transition with the inclined connecting portion 422. This transition avoids the right-angle obstruction that may occur when the connecting portion 422 is parallel to the first direction, reduces the impact force and resistance when the box piece 100 enters the pressing portion 423, and allows the box piece 100 to slide more easily into the effective range of the pressing portion 423. At the same time, the inclined connecting portion 422 can also play a certain guiding role for the box piece 100, helping the box piece 100 to maintain the correct posture before entering the pressing portion 423, and preventing jamming with the pressing portion 423 due to slight deviation of the box piece 100.
[0040] like Figure 1 and Figure 2 As shown, the conveying device also includes a fastener 6, which passes through the fixing plate 51 and the fixing part 421 in sequence and is threadedly connected to the mounting base 41. The fastener 6, by passing through the fixing plate 51 and the fixing part 421 in sequence and being threadedly connected to the mounting base 41, securely locks the three together, preventing relative displacement caused by vibration during the operation of the cigarette packaging machine or by the force exerted on the elastic element 42. This stable connection ensures a constant positional relationship between the adjusting component 5 and the elastic element 42, allowing the contact force of the threaded rod 52 on the elastic element 42 to be accurately transmitted to the pressing part 423, ensuring the stability and consistency of pressure adjustment. This, in turn, ensures that the pressure exerted by the elastic element 42 on the box sheet 100 is always controllable, maintaining the smoothness of the box sheet 100 conveying and reducing pressure fluctuations and conveying failures caused by loose components. In this embodiment, the fastener 6 is a screw or bolt.
[0041] In this embodiment, as Figure 1 and Figure 2 As shown, two fasteners 6 are spaced apart along the first direction. The two fasteners 6 are respectively threaded through the fixing plate 51 and the mounting base 41, further enhancing the connection stability between the adjusting component 5 and the elastic element 42.
[0042] like Figure 1 and Figure 2As shown, the adjustment assembly 5 also includes an operating member 53, which is fixedly connected to the end of the threaded rod 52 opposite to the connecting part 422. The operating member 53 provides a convenient point of force application for the rotation adjustment of the threaded rod 52. By rotating the operating member 53, the operator can easily drive the threaded rod 52 to rotate within the threaded hole of the fixed plate 51, thereby changing the contact force between the threaded rod 52 and the connecting part 422 of the elastic member 42. This design avoids the inconvenience of applying force or slippage that may occur when directly rotating the threaded rod 52, making the pressure adjustment operation more labor-saving and efficient. At the same time, the setting of the operating member 53 allows the operator to more accurately control the rotation angle of the threaded rod 52, thereby achieving fine adjustment of the pressure of the elastic member 42, further improving the accuracy of pressure adjustment, ensuring that the contact force of the elastic member 42 against the box piece 100 is always in the optimal state, effectively maintaining the stability of the box piece 100 conveying, and reducing pressure deviation and related conveying failures caused by inconvenient adjustment. In this embodiment, the operating member 53 is a hexagonal nut, which is fixedly connected to one end of the threaded rod 52 away from the connecting part 422. With the help of the hexagonal structure, it can be perfectly matched with common tools such as wrenches, providing a more reliable and labor-saving force application point for the rotation adjustment of the threaded rod 52.
[0043] like Figure 2 As shown, the conveying device includes two symmetrically arranged elastic pressing components 4 and two adjusting components 5. The two elastic pressing components 4 are respectively connected to two baffles 2, and each adjusting component 5 cooperates with one elastic pressing component 4. When the pressure of the corresponding elastic element 42 is adjusted by the adjusting components 5 on both sides, it can be ensured that the constraint force on the left and right sides of the box piece 100 is consistent, avoiding the box piece 100 from shifting or tilting to one side during the conveying process due to excessive or insufficient pressure on one side. At the same time, the elastic pressing components 4 on both sides, together with the baffles 2, can restrict the position of the box piece 100 from the left and right directions. Combined with the conveying force of the conveying component along the first direction, the box piece 100 always maintains a centered and stable posture on the conveying platform 1, effectively reducing problems such as conveying jams and blockages caused by uneven force. This symmetrical structure also allows operators to make precise pressure adjustments on both sides of the adjustment components 5 according to the specifications of the box piece 100 and the conveying requirements, further adapting to the conveying requirements of different types of box pieces 100, improving the versatility and adaptability of the conveying device, and ultimately ensuring the precise cooperation between the box piece 100 and the components in the subsequent processes, thereby improving product packaging quality and production efficiency.
[0044] like Figure 1 and Figure 2As shown, the conveying device also includes a receiving roller 7, whose two ends are rotatably connected to two baffles 2 respectively. The receiving roller 7 rolls against the box piece 100. The rolling contact of the receiving roller 7 with the box piece 100 plays an auxiliary role in positioning and pressing. Combined with the pressure of the elastic pressing component 4 on the box piece 100, it ensures that the box piece 100 maintains stable contact with the conveying platform 1 during the conveying process, reducing the bouncing or deviation of the box piece 100 caused by vibration or changes in vehicle speed. In addition, the setting of the receiving roller 7 can guide the box piece 100 to smoothly transition to the subsequent forming device, ensuring that the box piece 100 maintains a precise position and posture when entering the next stage. In conjunction with the elastic pressing component 4, adjusting component 5 and other structures, it further improves the smoothness and stability of the box piece 100 conveying, providing more reliable support for ensuring product packaging quality and improving production efficiency.
[0045] like Figure 1 and Figure 2 As shown, the conveying device also includes a brush assembly 8, located between the paper receiving roller 7 and the adjusting assembly 5. The brush assembly 8 includes a support 81, a brush plate 82, and brush bristles 83. The support 81 is fixedly installed and fixedly connected to the brush plate 82. The brush plate 82 is spaced apart from the conveying platform 1. The brush bristles 83 are provided on the side of the brush plate 82 facing away from the support 81, and the brush bristles 83 can press against the box sheet 100. The flexible nature of the brush bristles 83 provides continuous and gentle pressure to the box sheet 100. This flexible pressure is different from the hard contact of a rigid structure. It can closely fit the box sheet 100 without damaging its surface. This avoids excessive pressure that could obstruct the conveying of the box sheet 100, and effectively restrains the box sheet 100, preventing it from shifting or tilting during conveying due to vibration, speed changes, or other external forces. Meanwhile, the brush assembly 8, positioned between the receiving roller 7 and the adjusting assembly 5, forms a relay-style stable constraint with both: the box piece 100 first achieves initial stability through the elastic pressure of the adjusting assembly 5, then its posture is further consolidated by the flexible pressure of the brush assembly 8, and finally guided into the next stage by the rolling contact of the receiving roller 7. This multi-level constraint coordination ensures that the box piece 100 maintains a stable posture and precise position throughout the entire conveying path, improving the overall stability of the conveying device and its adaptability to the conveying of the box piece 100, providing more comprehensive support for ensuring product quality and improving production efficiency.
[0046] like Figure 1 and Figure 2As shown, the conveying assembly includes a drive unit and a pusher plate 31. The output end of the drive unit is fixedly connected to the pusher plate 31, which can abut against the box piece 100. The drive unit pushes the box piece 100 to move along the first direction through the pusher plate 31. The drive unit can output a continuous and uniform driving force, which acts directly on the box piece 100 through the pusher plate 31, ensuring that the box piece 100 moves smoothly along the first direction on the conveying platform 1, avoiding problems such as stagnation or jamming of the box piece 100 due to insufficient or unstable power. The abutment method between the pusher plate 31 and the box piece 100 allows the driving force to be transmitted to the box piece 100 more evenly, reducing deformation or displacement caused by excessive local force on the box piece 100. Combined with the limiting effect of the side baffles 2 and the constraint effect of the elastic pressing component 4, brush component 8, etc., the stability of the box piece 100's posture during movement is further guaranteed. At the same time, the driving force of the drive unit can be adjusted according to actual production needs to adapt to the conveying of box pieces 100 of different specifications and materials, improving the flexibility of the conveying device. This stable power output, combined with the synergistic effect of various constraint components, allows the tray 100 to move precisely according to a preset rhythm and path, laying a solid foundation for subsequent cooperation with components such as the receiving roller 7, and effectively improving the continuity and efficiency of the overall conveying process. In this embodiment, the driving component can be an electric actuator, a cylinder, etc.
[0047] In this embodiment, the conveying assembly also includes a lifting component, which is fixedly installed. The output end of the lifting component is connected to the driving component, and the output end of the lifting component can drive the driving component and the push plate 31 to reciprocate along a second direction, which is perpendicular to the first direction. In this embodiment, the first direction is a horizontal conveying direction, and the second direction is a vertical direction. When the box piece 100 needs to be pushed, the lifting component can drive the driving component and the push plate 31 to descend along the second direction, so that the push plate 31 accurately abuts against the box piece 100. Then, the driving component pushes the box piece 100 to move along the first direction through the push plate 31. After the pushing is completed, the lifting component drives the push plate 31 to rise and reset along the second direction, avoiding interference between the push plate 31 and subsequent box pieces 100, and ensuring that the next box piece 100 can smoothly enter the conveying position. This coordination of lifting and pushing actions makes the working trajectory of the push plate 31 more reasonable, which can reliably provide driving force for the box piece 100 and make room for the conveying of the box piece 100 in the non-working state, reducing the risk of collision between components. Meanwhile, for box sheets 100 of different thicknesses, the lifting mechanism can adjust the descent height of the push plate 31 to ensure effective contact between the push plate 31 and the box sheet 100, further improving the adaptability of the conveying device to box sheets 100 of different specifications. Combined with the constraint and guidance of the box sheet 100 by the elastic pressing component 4, the paper receiving roller 7, and other structures, the lifting mechanism drives the lifting action of the push plate 31, making the entire conveying process smoother and more orderly, effectively improving conveying efficiency and stability, and providing strong support for the smooth progress of subsequent packaging processes. In this embodiment, the lifting mechanism can be an electric push rod, a cylinder, etc.
