Description

Technical Field

[0001] This invention relates to the field of tobacco packaging technology, and in particular to a feeding mechanism and a conveying device. Background Technology

[0002] On a cigarette packaging production line, cigarette packs typically undergo basic processes such as conveying, stacking, finishing, and output. In the conveying process, cigarette packs are arranged sequentially. When they reach the stacking process, the cigarette packs are stacked in pairs to form double-layer cigarette pack units. The lifting process is used to convey the double-layer units one by one to a higher position. During the process of conveying to the higher position, the transparent paper on the cigarette packs can also be finished. Finally, after the lifting process, the cigarette packs enter the output process so that every five double-layer cigarette pack units form a group for output, preparing for subsequent boxing and sealing.

[0003] In the above process, the stacked double-layer units usually need to be sent to the lifting station. In automated packaging, the drive and conventional transmission mechanism often cause the stacking station to be idle when retracting, thus affecting the conveying efficiency. In addition, the increase in conveying speed of conventional transmission mechanism is limited by the mechanism itself.

[0004] Therefore, there is an urgent need for a material pushing mechanism to improve conveying efficiency and maintain a high-efficiency production pace. Summary of the Invention

[0005] The purpose of this invention is to provide a pushing mechanism and a conveying device to improve conveying efficiency and maintain a high-efficiency production rhythm.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A feeding mechanism, comprising:

[0008] frame;

[0009] The drive assembly is located on the rack;

[0010] The first linkage includes a first active linkage and a first driven linkage. The drive assembly is used to drive the first active linkage to reciprocate. The first active linkage is connected to the first driven linkage in a transmission manner so that the first active linkage drives the first driven linkage to reciprocate synchronously.

[0011] The second linkage includes a second driving linkage, a second driven linkage, and a third driven linkage. One end of the second driving linkage is connected to the drive assembly, which is used to drive the second driving linkage to swing back and forth. The second driving linkage and the second driven linkage are connected. One end of the second driven linkage is hinged to the first driven linkage, and one end of the third driven linkage is hinged to the first driving linkage.

[0012] The actuator is hinged to the other ends of the second driven rod and the third driven rod, so that the actuator can be driven to translate by the second and third driven rods in combination; wherein, within one motion cycle of the drive assembly, the actuator can push the product and perform multiple cycles according to a preset motion path, the preset motion path being that the actuator moves from the initial position to the middle position in the horizontal direction, and then moves upward from the middle position and returns to the initial position.

[0013] As an optional solution for the feeding mechanism, the driving component includes:

[0014] Driver source;

[0015] A first drive shaft is rotatably connected to the frame and is connected to the drive source in a transmission manner. A first active rod is sleeved on the first drive shaft, and the first drive shaft is used to drive the first active rod to swing.

[0016] The second drive shaft is rotatably connected to the frame and is drive-connected to the drive source. The second drive shaft is hinged to the first driven rod, and the second driving rod is connected to the second drive shaft.

[0017] The first link is hinged at both ends to the first driving link and the first driven link, respectively.

[0018] As an optional solution for the feeding mechanism, it includes:

[0019] The first swing arm is sleeved on the first drive shaft;

[0020] The second swing arm is sleeved on the second drive shaft;

[0021] A conjugate cam assembly is driven and connected to the drive source; the conjugate cam assembly is driven and connected to the first swing arm and the second swing arm respectively; the rotational motion of the conjugate cam assembly can synchronously cause the first swing arm and the second swing arm to swing back and forth, so as to cause the first drive shaft and the second drive shaft to rotate back and forth.

[0022] As an alternative to the pushing mechanism, the second rod group further includes a second connecting rod, the two ends of which are respectively hinged to the other end of the second driving rod and the second driven rod.

[0023] As an alternative to the feeding mechanism, the actuator rod is set horizontally, and one end of the actuator rod is provided with a push plate. The push plate and the actuator rod are set at right angles in the vertical plane, and the actuator rod is used to drive the push plate to push the product.

[0024] Conveying device, including:

[0025] A conveyor belt for conveying products, wherein one side of the conveyor belt has an overlapping area;

[0026] In any of the above embodiments, the pusher mechanism is at least partially used to push the product located in the stacking area onto the conveyor belt.

[0027] As an alternative to the conveying device, a stacking mechanism is included, the stacking mechanism comprising:

[0028] A push rod is driven to the drive assembly, which is used to reciprocate the push rod in a vertical direction so that the push rod pushes the product into the stacking area.

[0029] As an alternative to the conveying device, the following are included:

[0030] A first crank is connected to the drive assembly, which is used to drive the first crank to rotate.

[0031] The third link is hinged to one end of the first crank;

[0032] The first rocker arm, one end of the first rocker arm, the other end of the third connecting rod, and the push rod are coaxially hinged together, and the other end of the first rocker arm is hinged to the frame;

[0033] A second rocker arm is provided at a distance from the first rocker arm. One end of the second rocker arm is hinged to the push rod, and the other end of the second rocker arm is hinged to the frame.

[0034] As an alternative to a conveying device, a conveying mechanism is included, the conveying mechanism comprising:

[0035] A drive belt is used to transport products to the stacking area, and the drive belt is connected to the drive assembly.

[0036] A pressing component is connected to the driving component and is located above the transmission belt. When the push rod moves downward away from the stacking area, the pressing component moves downward and squeezes the product on the transmission belt, and the transmission belt feeds the product into the stacking area. When the push rod pushes the product in the stacking area upward, the pressing component rises synchronously.

[0037] As an alternative to the conveying device, the pressing assembly includes:

[0038] support;

[0039] Pressure rollers, a plurality of pressure rollers are arranged horizontally at intervals on the support, the pressure rollers being used to press the product.

[0040] Beneficial effects:

[0041] In a first aspect of the invention, a first driving rod is driven to a first driven rod, thereby causing the first driving rod and the first driven rod to reciprocate synchronously. A drive assembly is further driven to one end of a second driving rod, and one end of the second driven rod is hinged to the first driven rod, and one end of the third driven rod is hinged to the first driving rod; an actuator is hinged to the other ends of both the second and third driven rods, and the second and third driven rods are straight rods. The drive assembly drives the second driving rod to reciprocate, and the second driving rod drives the second driven rod to oscillate. The oscillation of the second and third driven rods is synchronized, and the ends of the second and third driven rods are respectively hinged to the actuator, thereby achieving horizontal translation of the actuator and enabling it to have a preset motion path. The motion path is determined by the motion of the actuator, and the motion of the actuator is determined by the transmission relationship between the first and second rod groups. In the pushing process, the actuator first moves horizontally from the initial position to the middle position, allowing the product to be directly pushed to the next conveying process. Then, the actuator moves upward from the middle position and returns to the initial position, thus avoiding interference with incoming products and effectively improving work efficiency. Furthermore, the first and second actuator groups ensure that the actuator performs multiple cycles along a preset path within the same motion cycle of the drive component, further increasing the pushing speed and achieving high-speed operation. The overall structure, using a single drive combined with the first and second actuator groups, is reliable and stable, eliminating the need for multiple drive matching and improving reliability.

[0042] In the second aspect, the conveying device based on this pusher mechanism can effectively improve the conveying efficiency and production rhythm of products. Attached Figure Description

[0069] Please see the appendix Figure 1 - Appendix Figure 12 This embodiment relates to a pushing mechanism and a conveying device.

[0070] Please refer to the appendix for details. Figure 1 - Appendix Figure 6In the first aspect, the feeding mechanism includes a frame 1, a drive assembly 2, a first rod group 3, a second rod group 4, and an actuator 5. The drive assembly 2 is mounted on the frame 1. The first rod group 3 includes a first driving rod 31 and a first driven rod 32. The drive assembly 2 drives the first driving rod 31 to reciprocate. The first driving rod 31 and the first driven rod 32 are connected in a transmission connection, so that the first driving rod 31 drives the first driven rod 32 to reciprocate synchronously. The second rod group 4 includes a second driving rod 41, a second driven rod 42, and a third driven rod 43. One end of the second driving rod 41 is connected to the drive assembly 2, and the drive assembly 2 drives the second driving rod 41 to reciprocate. The second driving rod 41 is connected to the second driven rod 42. The third driven rod 43... One end of the second driven rod 42 is hinged to the first driven rod 32, and one end of the third driven rod 43 is hinged to the first driving rod 31; the actuator 5 is hinged to the other ends of the second driven rod 42 and the third driven rod 43, so that the actuator 5 can be driven to translate by the second driven rod 42 and the third driven rod 43 in combination; wherein, within one motion cycle of the drive assembly 2, the actuator 5 can push the product 100 according to the preset motion path and perform multiple cycles. The preset motion path is that the actuator 5 moves from the initial position to the middle position in the horizontal direction, and then moves upward from the middle position and returns to the initial position.

[0071] It should be noted that this embodiment only introduces the operating principle from the perspective of the mechanism itself. Those skilled in the art should make adaptive adjustments to the size and shape of the parts in the mechanism according to the design requirements.

[0072] Specifically, frame 1 is a supporting and positioning structure, which can be a box or a frame. Frame 1 itself is a load-bearing body used to realize positioning, connection and support functions, and therefore has sufficient rigidity to resist deformation. Drive assembly 2 is located on frame 1. Drive assembly 2 has a drive source, which is a structure that directly outputs power. In this embodiment, the drive source is a servo motor. Moreover, in this embodiment, the same drive source is used in conjunction with multiple transmission structures to realize the coordinated operation of multiple mechanisms, reducing the number of drive sources and avoiding the matching design of multiple drive sources. The coordinated action of multiple mechanisms is realized only from the perspective of mechanical cooperation, so that the whole has extremely high stability and avoids problems such as matching adjustment of multiple drive sources and failure of multiple drive source cooperation.

[0073] The first driving rod 31 can be directly or indirectly connected to the drive assembly 2; this embodiment describes the indirect connection method. The first driving rod 31 is drive-connected to the first driven rod 32, causing them to reciprocate synchronously. The angle range of the reciprocating swing should be determined according to the planned path of the actuator 5. In this embodiment, the synchronous reciprocating swing amplitude of the first driving rod 31 and the first driven rod 32 does not exceed 180°. Both the first driving rod 31 and the first driven rod 32 are V-shaped curved rods with a 90° included angle. The lines connecting the endpoints of the first driving rod 31 and the first driven rod 32 form a parallelogram. The connection between the drive assembly 2 and the first driving rod 31 is located near the sharp corner of the V-shaped structure of the first driving rod 31.

[0074] The drive assembly 2 is driven to one end of the second driving rod 41, and one end of the second driven rod 42 is hinged to the first driven rod 32, while one end of the third driven rod 43 is hinged to the first driving rod 31. The actuator 5 is hinged to the other ends of both the second driven rod 42 and the third driven rod 43, and both the second and third driven rods 42 and 43 are straight rods. The drive assembly 2 drives the second driving rod 41 to reciprocate, and the second driving rod 41 drives the second driven rod 42 to swing. The swinging of the second and third driven rods 42 and 43 is synchronized, and their ends are respectively hinged to the actuator 5, thereby achieving horizontal translation of the actuator 5. This allows for a preset motion path, determined by the movement of the actuator 5. Simultaneously, the movement of the actuator 5 is determined by the transmission relationship between the first rod group 3 and the second rod group 4. The end of the actuator 5 can be used in various applications. Please refer to the appendix. Figure 3 - Appendix Figure 6 For example, in the pushing process of product 100 (product 100 can be a double-layer unit of stacked cigarette packs), the actuator 5 first moves from the initial position to the middle position along the horizontal direction, so that the double-layer unit can be directly pushed to the next conveying process. Then, the actuator 5 moves upward from the middle position and returns to the initial position, thus avoiding the approaching double-layer cigarette pack unit, thereby effectively improving work efficiency. On the other hand, the first rod group 3 and the second rod group 4 ensure that within the same motion cycle of the drive component 2, the actuator 5 cyclically executes multiple times according to the preset motion route, thereby further increasing the pushing speed and achieving high-speed operation. In this embodiment, this pushing mechanism can achieve a cigarette pack conveying speed of 600 packs / min, and the overall structure is reliable and stable due to the single drive combined with the first rod group 3 and the second rod group 4, eliminating the need for multiple drive matching and improving reliability.

[0075] Optionally, the drive assembly 2 includes a drive source, a first drive shaft 21, and a second drive shaft 22. The first drive shaft 21 is rotatably connected to the frame 1 and is driven by the drive source. A first active rod 31 is sleeved on the first drive shaft 21, and the first drive shaft 21 is used to drive the first active rod 31 to swing. The second drive shaft 22 is rotatably connected to the frame 1 and is driven by the drive source. The second drive shaft 22 is hinged to the first driven rod 32, and the second active rod 41 is connected to the second drive shaft 22. The two ends of the first connecting rod 33 are respectively hinged to the first active rod 31 and the first driven rod 32.

[0076] Specifically, the drive source is a servo motor mounted on the frame 1. This single drive source synchronously drives the first drive shaft 21 and the second drive shaft 22. The first active rod 31 is sleeved on the first drive shaft 21 and can be connected by a key to transmit force and motion from the first drive shaft 21 to the first active rod 31, thereby achieving the reciprocating oscillation of the first active rod 31. The frame 1 supports the first drive shaft 21 and the second drive shaft 22 via bearings, allowing the first drive shaft 21 and the second drive shaft 22 to be rotatably connected to the frame 1. Furthermore, the second drive shaft 22 is hinged to the first driven rod 32; that is, the second drive shaft 22 does not transmit power or motion to the first driven rod 32, but only provides a rotational support position for the first driven rod 32. The first driven rod 32 and the second drive shaft 22 are connected by bearings to ensure the flexibility of the first driven rod 32's rotation around the second drive shaft 22. The first link 33 is a straight rod and is used to connect the first driving rod 31 and the first driven rod 32, so that the force and motion of the first driving rod 31 are transmitted to the first driven rod 32 through the first link 33, and the first driven rod 32 and the first driving rod 31 rotate synchronously.

[0077] Furthermore, the feeding mechanism also includes a conjugate cam assembly 23, a first swing arm 24, and a second swing arm 25. The first swing arm 24 is sleeved on the first drive shaft 21, and the second swing arm 25 is sleeved on the second drive shaft 22. The conjugate cam assembly 23 is driven and connected to the drive source. The conjugate cam assembly 23 is connected to the first swing arm 24 and the second swing arm 25 respectively. The rotational movement of the conjugate cam assembly 23 can synchronously cause the first swing arm 24 and the second swing arm 25 to swing back and forth, so as to cause the first drive shaft 21 and the second drive shaft 22 to swing back and forth.

[0078] In this embodiment, the drive source directly drives the conjugate cam assembly 23 to rotate. The conjugate cam assembly 23 includes two coaxial first conjugate cams 23-1 and second conjugate cams 23-2. Each of the first conjugate cams 23-1 and 23-2 includes a main cam and a secondary cam, and the main cam and the secondary cam have the same axis of rotation. The first rocker arm 24 and the second rocker arm 25 are V-shaped. Rollers are provided at both ends of the first rocker arm 24 to maintain contact with the main cam and the secondary cam of the first conjugate cam 23-1, respectively. Rollers are also provided at both ends of the second rocker arm 25 to maintain contact with the main cam and the secondary cam of the second conjugate cam 23-2, respectively. Based on the conjugate cam group 23, the drive source can drive the first conjugate cam 23-1 and the second conjugate cam 23-2 to rotate. The rotation of the first conjugate cam 23-1 and the second conjugate cam 23-2 respectively drives the first swing arm 24 and the second swing arm 25 to swing within a certain angle. The first swing arm 24 and the second swing arm 25 are respectively connected to the first drive shaft 21 and the second drive shaft 22, so that the first drive shaft 21 and the second drive shaft 22 reciprocate within a certain angle.

[0079] In this embodiment, based on the conjugate cam assembly 23, the first swing arm 24, and the second swing arm 25, the first drive shaft 21 and the second drive shaft 22 can reciprocate within a certain angle range during the continuous rotational output of a single drive source. The transmission mechanism is stable and reliable, and there are no requirements for drive matching, thus improving the stability of the structure.

[0080] Optionally, the second linkage 4 also includes a second connecting rod 44, the two ends of which are respectively hinged to the other end of the second driving rod 41 and the second driven rod 42.

[0081] Specifically, the second connecting rod 44 is a straight rod. One end of the second connecting rod 44 is hinged to the other end of the second driving rod 41 via a bearing, and the other end of the second connecting rod 44 is hinged to the middle part of the second driven rod 42. In this embodiment, the second driven rod 42, the actuator 5, and the third driven rod 43 form a double rocker mechanism. The second driving rod 41 provides power, driving the mechanism to move through the second connecting rod 44. The first driving rod 31, the first connecting rod 33, and the first driven rod 32 form another double rocker mechanism. Both of the above double rocker mechanisms are parallelogram-shaped hinged four-bar mechanisms. During the movement, it can be ensured that the actuator 5 always remains parallel and horizontal to the center line connecting the first drive shaft 21 and the second drive shaft 22. During the movement of the entire pushing mechanism, the first connecting rod 33 also remains parallel to the center line connecting the first drive shaft 21 and the second drive shaft 22.

[0082] Optionally, the actuator 5 is set in a horizontal direction, and one end of the actuator 5 is provided with a push plate 51. The push plate 51 and the actuator 5 are set at right angles in the vertical plane. The actuator 5 is used to drive the push plate 51 to push the product 100.

[0083] Since the push plate 51 is installed perpendicularly to the actuator 5, the push plate 51 will remain vertical throughout the entire movement due to the motion characteristics of the actuator 5. This ensures that the push plate 51 will not be misaligned when pushing the product 100 due to rotation, thus preventing the product 100 from falling. Furthermore, under the continuous drive of the conjugate cam group 23, the second driven rod 42 reciprocates around the lower hinge point of the first driven rod 32, and the third driven rod 43 reciprocates around the lower hinge point of the first driving rod 31, thereby driving the push plate 51 to move. At the same time, the second driven rod 42 and the third driven rod 43 are further driven by the first rod group 3. The combination of these two movements allows the push plate 51 to move along the motion trajectory of the actuator 5. Adaptably, corresponding to the pushing of the product 100, the push plate 51 can also push the product 100 according to the preset motion path of the actuator 5 and perform multiple cycles.

[0084] The second aspect of this embodiment relates to a conveying device including a conveyor belt 6 and more pushing mechanisms, wherein the conveyor belt 6 is used to convey a product 100, and one side of the conveyor belt 6 has a stacking area 61; an actuating rod 5 is at least partially used to push the product 100 located in the stacking area 61 onto the conveyor belt 6.

[0085] Specifically, based on product 100 being a double-layer unit of stacked cigarette packs, conveyor belt 6 transports the double-layer unit. Conveyor belt 6 can be used to connect the subsequent placement process and the preceding stacking process. The conveyor belt 6 can be flexibly configured based on the spatial positions of the placement and stacking processes. For example, if the placement and stacking processes have a height difference, the conveying direction of conveyor belt 6 is vertical. This conveying method needs to consider preventing the double-layer unit from falling during transport. Therefore, conveyor belt 6 can adopt a relatively opposing double-sided belt configuration to clamp the double-layer unit. To ensure the reliability and orderliness of the double-layer unit transport, several raised baffles are fixed at equal intervals along the conveying direction on the surface of conveyor belt 6. The space between every two adjacent baffles forms a limiting area for accommodating the double-layer unit. Furthermore, the baffles can be an integral part of the conveyor belt 6.

[0086] Of course, if the placement process and the stacking process have the same horizontal height, the conveyor belt 6 can also be arranged horizontally to transport the double-layer units. This conveying method does not need to consider the problem of preventing the double-layer units from falling during the conveying process. It only needs to ensure that there is enough friction to make the double-layer units move stably.

[0087] In this embodiment, a stacking area 61 is formed on one side of the conveyor belt 6. Within the stacking area 61, cigarette packs conveyed one by one can be stacked to form a double-layer unit. The double-layer unit located in the stacking area 61 can be smoothly fed into the conveyor belt 6 by the actuator 5 of the pushing mechanism. The conveying device based on this pushing mechanism can improve the conveying efficiency.

[0088] Please see the appendix Figure 7 - Appendix Figure 9 Optionally, the conveying device further includes a stacking mechanism 7, which includes a push rod 71. The push rod 71 is connected to the drive assembly 2 for transmission. The drive assembly 2 is used to reciprocate the push rod 71 in the vertical direction so that the push rod 71 pushes the product 100 into the stacking area 61.

[0089] Specifically, to enable the individually conveyed cigarette packs to be stacked into a double-layer unit, this embodiment further includes a stacking mechanism 7. The stacking mechanism 7 includes a push rod 71, a first crank 72, a third connecting rod 73, a first rocker arm 74, and a second rocker arm 75. The first crank 72 is connected to the drive assembly 2, which drives the first crank 72 to rotate. The first crank 72 is hinged to one end of the third connecting rod 73. One end of the first rocker arm 74, the other end of the third connecting rod 73, and the push rod 71 are coaxially hinged, and the other end of the first rocker arm 74 is hinged to the frame 1. The second rocker arm 75 is spaced apart from the third rocker arm, with one end of the second rocker arm 75 hinged to the push rod 71 and the other end of the second rocker arm 75 hinged to the frame 1.

[0090] In this embodiment, the first crank 72 performs circular motion, driving the third connecting rod 73 to swing. Simultaneously, the third connecting rod 73 drives the first rocker arm 74 to swing. The first rocker arm 74 acts as the driving element, moving the push rod 71. Since it is necessary to ensure that the push rod 71 moves reciprocally in the vertical direction, this embodiment further includes a second rocker arm 75. The second rocker arm 75 is parallel to the first rocker arm 74, and the hinged ends of the first rocker arm 74 and the hinged ends of the second rocker arm 75 are connected sequentially to form a parallelogram. During the movement, the first rocker arm 74 and the second rocker arm 75 remain parallel. The push rod 71 is constrained at two points by the first rocker arm 74 and the second rocker arm 75, ensuring that it can only move reciprocally in the vertical direction with the reciprocating swing of the first rocker arm 74.

[0091] In this embodiment, the first crank 72 is still driven to rotate by the drive component 2, so a single drive form is still used. Combined with the mechanical stacking mechanism 7, the rhythm and stability of the stacking action can be guaranteed.

[0092] Please see the appendix Figure 4 - Appendix Figure 6 and appendix Figure 10 - Appendix Figure 12Optionally, the conveying device further includes a conveying mechanism 8, which includes a drive belt 81 and a pressing assembly 82. The drive belt 81 is used to convey the product 100 to the stacking area 61, and the drive belt 81 is connected to the drive assembly 2. The pressing assembly 82 is connected to the drive assembly 2 and is located above the drive belt 81. When the push rod 71 moves downward away from the stacking area 61, the pressing assembly 82 moves downward and squeezes the product 100 on the drive belt 81, and the drive belt 81 sends the product 100 into the stacking area 61. When the push rod 71 pushes the product 100 in the stacking area 61 upward, the pressing assembly 82 rises synchronously.

[0093] Specifically, the transmission belt 81 is used to transport cigarette packs one by one, and the transmission belt 81 is connected to the drive assembly 2. The pressing assembly 82 includes a bracket 821 and a pressure roller 822. The pressure roller 822 can rotate. Multiple pressure rollers 822 are spaced horizontally on the bracket 821. The pressure roller 822 is used to press the product 100. The pressing assembly 82 is connected to the driving assembly 2. The pressing assembly 82 also includes a second crank 823 and a fourth connecting rod 824, as well as a slider 825 and a connecting rod 826. The driving assembly 2 is connected to the second crank 823 to drive the second crank 823 to rotate. The second crank 823 drives the fourth connecting rod 824 to move, thereby causing the slider 825 to reciprocate in the vertical direction. The slider 825 is connected to one end of the connecting rod 826, and the bracket 821 is connected to the other end of the connecting rod 826. Through the reciprocating movement of the slider 825, the bracket 821 is moved reciprocally in the vertical direction, driving the pressure roller 822 to move downward and squeeze the cigarette pack on the transmission belt 81, or to disengage the cigarette pack from the compression transmission belt 81. Drive assembly 2 transmits power to the first crank 72 and the second crank 823 via gear set 26, thereby driving the stacking mechanism 7 and the pressing assembly 82 respectively. Furthermore, by setting the transmission ratio, the first crank 72 and the second crank 823 are ensured to rotate the same number of revolutions within the same time period. The starting positions of the first crank 72 and the second crank 823 of the two mechanisms are then adjusted, thus coordinating the movements of the two stacking mechanisms 7 and the conveying mechanism 8. When the push rod 71 moves downwards away from the stacking area 61, the pressing assembly 82 moves downwards and presses against the transmission belt 81. The cigarette pack is pushed up, thereby increasing the friction between the cigarette pack and the conveyor belt 81, and the conveyor belt 81 is used to send the cigarette pack into the stacking area 61. When the push rod 71 pushes the cigarette pack in the stacking area 61 upward, the pressing component 82 rises simultaneously. The stacking mechanism 7 stops the cigarette pack from being continuously transported to the stacking area 61. When the push rod 71 moves downward again away from the stacking area 61, the pressing component 82 moves downward and squeezes the product 100 on the conveyor belt 81 again, so that the second cigarette pack is transported to the stacking area 61. The push rod 71 pushes up the second cigarette pack to achieve the stacking of two adjacent cigarette packs.
