Description

Technical Field

[0001] This application relates to the field of packaging bag production, and in particular to an auxiliary conveying device for packaging bags. Background Technology

[0002] In modern industrial production, packaging bags are a common form of product packaging and are widely used in food, chemical, agricultural products and daily consumer goods. With the continuous improvement of production automation, the preceding processes such as material filling and sealing have basically achieved continuous and automated operation. The finished bags after packaging need to be transported efficiently and smoothly to the subsequent palletizing, boxing or warehousing stages. In this process, it is often necessary to lay down the upright or tilted packaging bags to adapt to the layout or operation requirements of the subsequent production line.

[0003] In existing technologies, direction changes are achieved by connecting multiple conveyor belts with guide rails, or by using robotic arms for grasping and flipping. These types of equipment are usually complex in structure, occupy a large space, and have high costs. Furthermore, they have limited adaptability to packaging bags of different sizes and materials. Under high-speed and continuous production cycles, their stability and durability face challenges.

[0004] Currently, in some production lines that cannot meet the demand for sufficient production space or have a small production scale, the common practice in the conveying and posture transformation of packaging bags is still to rely on manual handling and laying, or to use simple mechanical push plates, stop bars and other devices for assistance.

[0005] Manual operation is not only labor-intensive and inefficient, but also prone to squeezing, tearing or leakage of contents during the laying process due to inconsistent operating force or angle. This is especially true for soft packaging bags containing powdery or granular materials. Simple mechanical devices often lack precise synchronization and control, which can easily cause uneven force on the bags, deviation or jamming when pushing them. Similarly, it is difficult to ensure the smoothness and reliability of the laying action. Summary of the Invention

[0006] The purpose of this application is to address the problems mentioned in the background art, namely that manual operation is not only labor-intensive and inefficient, but also prone to squeezing, tearing, or leakage of contents during the laying process of packaging bags due to inconsistent operating force or angle, especially for soft packaging bags containing powdery or granular materials. Simple mechanical devices often lack precise synchronization and control, which can easily cause uneven force on the bags, deviation, or jamming when pushing them, and it is also difficult to ensure the stability and reliability of the laying action. This application provides a packaging bag auxiliary conveying device.

[0007] To achieve the above objectives, this application specifically adopts the following technical solution: A packaging bag auxiliary conveying device includes a conveyor belt 1, a conveyor belt 2 placed at one end of the conveyor belt 1, and a conveyor belt 3 placed on one side of the conveyor belt 1. The conveyor belts 1, 2, and 3 are all installed on the ground. An auxiliary tilting mechanism is provided on the side of the conveyor belt 1 away from the conveyor belt 3. The auxiliary tilting mechanism includes a support frame 1 disposed on one side of the conveyor belt 1 and fixed to the ground. A support frame 2 is fixed on the support frame 1. A push plate is disposed between the support frame 2 and the conveyor belt 1. A pushing component is disposed between the support frame 2 and the push plate. A limit rod is provided on the side of the conveyor belt 1 away from the support frame 1. A support component is disposed between the limit rod and the support frame 2. An auxiliary lifting component is disposed between the limit rod and the push plate. A control box is fixed on one side of the support frame 1.

[0008] By adopting the above technical solution, the packaging bag moves onto conveyor belt two. The pushing component drives the pusher plate, which pushes the packaging bag onto conveyor belt three. At this point, the limit rod blocks the upper part of the packaging bag, thus enabling the packaging bag to be laid down smoothly. This effectively avoids damage or leakage of contents caused by uneven force during the tilting process, effectively improving the automation level and work efficiency of packaging bag conveying and tilting. At the same time, it avoids packaging bag damage or conveying jams that may occur due to manual operation.

[0009] Furthermore, the pushing component includes two support blocks symmetrically fixed on the second support frame, a rotating shaft rotatably connecting the two support blocks, a pushing frame fixed on the rotating shaft, the pushing frame being inverted L-shape, the pushing frame being fixedly connected to the pushing plate, and a driving component being provided between the pushing frame and the first support frame.

[0010] By adopting the above technical solution, the driving component drives the push frame to rotate around the rotating axis, realizing the reciprocating swing of the push plate, thereby stably pushing the packaging bag from conveyor belt one to conveyor belt three, effectively improving the automation level and work efficiency of packaging bag conveying and laying, and avoiding the packaging bag from shifting or tipping over during the pushing process.

[0011] Furthermore, the driving component includes a support plate one fixed on a support frame one, a support plate two fixed on the pushing frame, an electric telescopic rod between the support plate one and the support plate two, the base end of the electric telescopic rod being rotatably connected to the support plate one, and the output end of the electric telescopic rod being rotatably connected to the support plate two.

[0012] By adopting the above technical solution, the output end of the electric telescopic rod extends outward. The extension action will push the support plate two to drive the push frame to rotate around the rotating axis, thereby causing the push plate to swing in the three directions of the conveyor belt. This ensures that the distance and angle of each push by the push plate are consistent, effectively guaranteeing the stability and repeatability of the packaging bag pushing action, and adapting to the continuous and efficient operation requirements of automated production lines.

[0013] Furthermore, the support assembly includes a connecting frame fixed to one end of the second support frame away from the first support frame, a support leg frame fixed to one end of the connecting frame away from the second support frame, the end of the support leg frame away from the connecting frame touching the ground, and a connector provided between the support leg frame and the limiting rod.

[0014] By adopting the above technical solution, the rigid connection between the connecting frame and the support leg frame, and the use of connectors to rotate and support the limiting rod, ensures the overall structural stability of the support component. It can withstand the reaction force generated by the limiting rod when blocking the packaging bag, and gives the limiting rod sufficient freedom of movement so that it can accurately respond to the action of the auxiliary lifting component.

[0015] Furthermore, the connector includes two connecting rods symmetrically rotatably connected to the support leg frame, a support shaft is fixed between the two connecting rods, the support shaft passes through the limiting rod and is rotatably connected to the limiting rod.

[0016] By adopting the above technical solution, the support shaft is supported by two rotatably connected connecting rods, and the support shaft supports the limiting rod. This ensures stable blocking of the upper part of the packaging bag, guarantees the freedom of the limiting rod, and reduces hard collisions between the limiting rod and the packaging bag, thereby reducing the risk of packaging bag damage.

[0017] Furthermore, a grating signal transmitter is fixed on one side of the conveyor belt one near the end of the conveyor belt two, and a grating signal receiver is fixed on the side of the conveyor belt one away from the grating signal transmitter.

[0018] By adopting the above technical solution, a grating signal transmitter and a grating signal receiver are respectively installed on both sides of the end of conveyor belt one near conveyor belt two, thereby realizing the automatic detection and action triggering of the device, ensuring that each packaging bag can be pushed in the accurate position, and improving the automation accuracy and working stability of the device.

[0019] Furthermore, the auxiliary lifting assembly includes a lifting gear mounted on the support leg frame. The lifting gear is fixedly connected to the rotating end of one of the connecting rods. A limit frame is mounted on the lifting gear and fixedly connected to the support leg frame. A lifting rack is slidably connected to the limit frame. The edge of the lifting gear intrudes into the limit frame. The lifting gear meshes with the lifting rack. A synchronizing element is provided between the push plate and the lifting rack.

[0020] By adopting the above technical solution, the meshing transmission between the lifting rack and the lifting gear, combined with the guiding constraint of the limiting frame on the lifting rack, ensures the straightness of the lifting rack during the sliding process, thereby accurately controlling the rotation angle of the lifting gear, making the action of the connecting rod driving the limiting rod more stable and reliable, ensuring that the limiting rod presses down to block in time during the pushing of the packaging bag, and quickly lifts up to reset after the pushing is completed.

[0021] Furthermore, the synchronizing element includes a synchronizing rod fixed to one side of the push plate, and a synchronizing bar is fixed to one end of the lifting rack near the synchronizing rod, with the synchronizing rod and the synchronizing bar slidably connected.

[0022] By adopting the above technical solution, the movement of the push plate and the movement of the lifting rack are connected by the synchronization rod and synchronization bar, thereby ensuring that the movements of the push component and the auxiliary lifting component are always precisely synchronized, avoiding the jamming or interference problems caused by the different movement trajectories of the two, and improving the smoothness and coordination of the overall movement of the device.

[0023] In summary, this application includes at least one of the following beneficial effects; 1. In this application, after the packaging bag moves onto conveyor belt one, conveyor belt one stops moving, and the pushing component is activated. The pushing component directly drives the pushing plate, and the end of the pushing plate near conveyor belt one gradually moves towards conveyor belt three. Under the push of the pushing plate, the bottom of the packaging bag contacts conveyor belt three. While the pushing plate pushes the packaging bag, it drives the auxiliary lifting component, which in turn drives the limiting rod on the support component to press down, so that the limiting rod blocks in front of the packaging bag. Conveyor belt three moves the packaging bag. During the movement, because conveyor belt three continuously provides forward conveying force, the upper part of the packaging bag will tilt backward under the obstruction of the limiting rod, while the lower part continues to move under the drive of conveyor belt three. Ultimately, the packaging bag is laid down smoothly. Simultaneously, the pushing component drives the push plate to reset. During the reset process, the push plate uses an auxiliary lifting mechanism to lift the limit rod on the support component, achieving a smooth laying down of the packaging bag. This effectively prevents damage or leakage of contents due to uneven force during the tilting process. It ensures that the limit rod is pressed down or lifted at the appropriate time, without affecting the conveying of the packaging bag, and reliably completes the laying operation. This effectively improves the automation level and work efficiency of packaging bag conveying and laying, while occupying less space, making it suitable for production lines with limited production space and scale. It also avoids packaging bag damage or conveying jams that may occur due to manual operation.

[0024] 2. In this application, by having the auxiliary lifting component and one of the connecting rods rotate synchronously around the rotation point of the support leg frame, and since the two connecting rods are symmetrically distributed and fixedly connected by the support shaft, the other connecting rod rotates in the same direction. The support shaft drives the limiting rod to rotate around its connection point with the connecting rod, thereby realizing the downward or upward action of the limiting rod. The two symmetrically arranged connecting rods make the force on the support shaft more even. The rotational connection design between the support shaft and the limiting rod effectively avoids the problem of support shaft tilting or deformation that may be caused by a single rod connection, extends the service life of the connecting parts, and at the same time, it can effectively reduce the friction between the limiting rod and the packaging bag when the limiting rod blocks the packaging bag, thereby reducing the risk of packaging bag breakage.

[0025] 3. In this application, when the push plate swings in three directions toward the conveyor belt, the push plate synchronously drives the lifting rack to slide along the length of the limiting frame through the synchronizing component. Since the lifting rack is meshed with the lifting gear, the sliding of the lifting rack will drive the lifting gear to rotate. The lifting gear drives the connecting rod fixed to it to rotate synchronously. Then, through the linkage between the two connecting rods and the support shaft, the limiting rod rotates downward around the support shaft, forming an effective blockage on the upper part of the packaging bag. When the pushing action is completed, the pushing component drives the push plate to reset. The push plate drives the lifting rack to slide along the limiting frame through the synchronizing component. The lifting rack drives the lifting gear to rotate in the opposite direction. The connecting rod rotates in the opposite direction as well. The limiting rod is lifted upward around the support shaft and returns to the initial position that does not affect the conveying of the packaging bag. This ensures that the subsequent packaging bags can move smoothly on the three conveyor belts, achieving straightness during the sliding process of the lifting rack. This allows for precise control of the rotation angle of the lifting gear, making the action of the connecting rod driving the limiting rod more stable and reliable. This ensures that the limiting rod presses down to block the packaging bag in time during the pushing process and quickly lifts up to reset after the pushing is completed.

[0028] The following is in conjunction with the appendix Figure 1 —6 provides further details regarding this application.

[0029] This application discloses an auxiliary conveying device for packaging bags.

[0030] Reference Figure 1 , Figure 2 and Figure 3 A packaging bag auxiliary conveying device includes a conveyor belt 1, a conveyor belt 2 at one end of the conveyor belt 1, and a conveyor belt 3 on one side of the conveyor belt 1. The conveyor belts 1, 2, and 3 are all installed on the ground. An auxiliary tilting mechanism 4 is provided on the side of the conveyor belt 1 away from the conveyor belt 3. The auxiliary tilting mechanism 4 includes a support frame 41 on one side of the conveyor belt 1, which is fixed to the ground. A support frame 42 is fixed on the support frame 41. A push plate 43 is provided between the support frame 42 and the conveyor belt 1. A pushing component 44 is provided between the support frame 42 and the push plate 43. A limit rod 45 is provided on the side of the conveyor belt 1 away from the support frame 41. A support component 46 is provided between the limit rod 45 and the support frame 42. An auxiliary lifting component 47 is provided between the limit rod 45 and the push plate 43. A control box 5 is fixed on one side of the support frame 41.

[0031] In an automated packaging production line for solid powder materials, the material is filled and sealed to form individual packaging bags, which are then conveyed by conveyor belt 2 to conveyor belt 1. After the packaging bags move onto conveyor belt 1, conveyor belt 1 stops moving, and the pushing component 44 is activated. The pushing component directly drives the pushing plate 43, and the end of the pushing plate 43 near conveyor belt 1 gradually moves towards conveyor belt 3. Under the pushing of the pushing plate 43, the bottom of the packaging bag comes into contact with conveyor belt 3. While the pushing plate 43 pushes the packaging bag, the pushing plate 43 also... The auxiliary lifting component 47 drives the limiting rod 45 on the support component 46 to press down, blocking the packaging bag. The conveyor belt 3 moves the packaging bag. During the movement, due to the continuous forward conveying force provided by the conveyor belt 3, the upper part of the packaging bag will tilt backward under the obstruction of the limiting rod 45, while the lower part will continue to move under the drive of the conveyor belt 3, ultimately achieving a smooth laying down of the packaging bag. At the same time, the pushing component 44 drives the push plate 43 to reset. During the reset process of the push plate 43, the push plate 4... 3. The auxiliary lifting mechanism lifts the limiting rod 45 on the support component 46, ensuring that the limiting rod 45 does not obstruct the packaging bag during its movement on the third conveyor belt 3. Then, it waits for the next packaging bag to move onto the second conveyor belt 2 and continues the bag-laying operation. When the packaging bag is moved onto the second conveyor belt 2, the pushing component 44 drives the pushing plate 43, which pushes the packaging bag onto the third conveyor belt 3. At this point, the limiting rod 45 blocks the top of the packaging bag, ensuring a smooth laying down. This effectively prevents damage or leakage of contents due to uneven force during the laying process. Simultaneously, the pushing component 44 and the auxiliary lifting component 47 move synchronously, ensuring that the limiting rod 45 is pressed down or raised at the appropriate time. This does not affect the conveying of the packaging bag and reliably completes the laying operation, effectively improving the automation and efficiency of the bag conveying and laying process. It also occupies less space, making it suitable for production lines with limited space and scale, while avoiding problems such as bag damage or conveying jams that may occur with manual operation.

[0032] Reference Figure 4 and Figure 5 The pushing component 44 includes two support blocks 444 symmetrically fixed on the second support frame 42. A rotating shaft 441 is rotatably connected between the two support blocks 444. A pushing frame 442 is fixed on the rotating shaft 441. The pushing frame 442 is inverted L-shaped. The pushing frame 442 is fixedly connected to the pushing plate 43. A driving component 443 is provided between the pushing frame 442 and the first support frame 41.

[0033] When control box 5 receives the packaging bag arrival signal from conveyor belt 2, drive component 443 drives push frame 442, causing push frame 442 to rotate around the rotation axis 441 between the two support blocks 444. Since push frame 442 is fixedly connected to push plate 43, push plate 43 rotates synchronously with push frame 442. Its end near conveyor belt 1 gradually moves towards conveyor belt 3, smoothly pushing the packaging bag on conveyor belt 1 towards conveyor belt 3. After the packaging bag is pushed to conveyor belt 3 and the falling action is completed, control box 5 sends a reset signal, and drive component 443 drives... As the moving frame rotates, the push plate 43 returns to its initial position, waiting for the next packaging bag to enter the conveyor belt 1. This achieves the cyclical operation of the pushing component 44. The driving component 443 drives the pushing frame 442 to rotate around the rotating shaft 441, realizing the reciprocating swing of the push plate 43. This can stably push the packaging bag from the conveyor belt 1 to the conveyor belt 3, preventing the packaging bag from shifting or tipping over during the pushing process. At the same time, the inverted L-shaped pushing frame 442 not only ensures a firm connection with the push plate 43, but also provides a reasonable spatial layout for the installation of the driving component 443, making the overall structure more harmonious.

[0034] Reference Figure 4 and Figure 5 The driving component 443 includes a support plate 4431 fixed on the support frame 41, a second support plate 4432 fixed on the push frame 442, an electric telescopic rod 4433 between the support plate 4431 and the second support plate 4432, the base end of the electric telescopic rod 4433 being rotatably connected to the support plate 4431, and the output end of the electric telescopic rod 4433 being rotatably connected to the second support plate 4432.

[0035] When the control box 5 issues a push command, the output end of the electric telescopic rod 4433 extends outward. Since its base end is rotatably connected to the support plate 1 4431 and its output end is rotatably connected to the support plate 2 4432, the extension action will push the support plate 2 4432 to drive the push frame 442 to rotate around the rotating shaft 441, thereby causing the push plate 43 to swing towards the conveyor belt 3. After the packaging bag has finished the lying down action, the control box 5 issues a reset signal, the output end of the electric telescopic rod 4433 retracts, pulls the support plate 2 4432 to drive the push frame 442 to rotate, and the push plate 43 returns to the initial position. By making the linear telescopic motion of the electric telescopic rod 4433 smoothly converted into the rotational motion of the push frame 442, it can be ensured that the distance and angle of each push by the push plate 43 are consistent, effectively ensuring the stability and repeatability of the packaging bag pushing action, and adapting to the continuous and efficient operation requirements of the automated production line.

[0036] Reference Figure 5 and Figure 6The support component 46 includes a connecting frame 461 fixed to the end of the second support frame 42 away from the first support frame 41. A support leg frame 462 is fixed to the end of the connecting frame 461 away from the second support frame 42. The end of the support leg frame 462 away from the connecting frame 461 abuts against the ground. A connector 463 is provided between the support leg frame 462 and the limiting rod 45.

[0037] The connector 463, through a rotatable connection, allows the limiting rod 45 to rotate flexibly around the connection point on the support leg frame 462. When the push plate 43 pushes the packaging bag towards the conveyor belt 3, the auxiliary lifting component 47, through the connector 463, drives the limiting rod 45 to rotate downwards around its connection axis with the support leg frame 462 until the lower end of the limiting rod 45 abuts against the edge above the conveyor belt 3, effectively blocking the upper part of the packaging bag. When the push plate 43 resets, the auxiliary lifting component 47 acts in the opposite direction on the connector 463, causing the limiting rod 45 to rotate upwards around the connection axis, returning to its initial position that does not affect the conveying of the packaging bag. The rigid connection between the connecting frame 461 and the support leg frame 462 ensures the overall stability of the support component 46 and can withstand the reaction force generated by the limiting rod 45 when blocking the packaging bag. This prevents the limiting rod 45 from shifting due to structural deformation, which would affect the lowering effect. At the same time, the rotation design of the connecting piece 463 gives the limiting rod 45 sufficient freedom of movement, enabling it to accurately respond to the action of the auxiliary lifting component 47 and complete the pressing or lifting at the appropriate time. This ensures effective blocking of the packaging bag without interfering with the conveyor belt 3, further improving the overall reliability and adaptability of the device.

[0038] Reference Figure 5 and Figure 6 The connector 463 includes two symmetrically rotatably connected connecting rods 4631 on the support leg frame 462. A support shaft 4632 is fixed between the two connecting rods 4631. The support shaft 4632 passes through the limiting rod 45 and is rotatably connected to the limiting rod 45.

[0039] When the auxiliary lifting assembly 47 rotates synchronously with one of the connecting rods 4631 around the rotation point of the support leg frame 462, the other connecting rod 4631 rotates in the same direction due to the symmetrical distribution of the two connecting rods 4631 and their fixed connection via the support shaft 4632. The support shaft 4632 then drives the limiting rod 45 to rotate around its connection point with the connecting rod 4631, thus achieving the downward or upward movement of the limiting rod 45. The two symmetrically arranged connecting rods 4631 ensure more even force distribution on the support shaft 4632, effectively avoiding potential issues with the support shaft 4632 caused by a single rod connection. 2. The tilting or deformation problem extends the service life of the connector 463. At the same time, the rotating connection design between the support shaft 4632 and the limiting rod 45 can effectively reduce the friction between the limiting rod 45 and the packaging bag when blocking the packaging bag. By using two rotating connecting rods 4631 to support the support shaft 4632, and the support shaft 4632 to support the limiting rod 45, it can ensure stable blocking of the upper part of the packaging bag, and reduce the hard collision between the limiting rod 45 and the packaging bag, thus reducing the risk of packaging bag damage.

[0040] Reference Figure 1 , Figure 2 and Figure 3 A grating signal transmitter 6 is fixed on one side of conveyor belt 1 near one end of conveyor belt 2, and a grating signal receiver 7 is fixed on the side of conveyor belt 1 away from the grating signal transmitter 6.

[0041] When a packaging bag is conveyed from conveyor belt 2 to one end of conveyor belt 1 near conveyor belt 2, the packaging bag will block the infrared beam emitted by the grating signal transmitter 6 to the grating signal receiver 7. At this time, the grating signal receiver 7 will feed back the detection signal to the control box 5, and conveyor belt 1 will start, maintaining the same transmission speed as conveyor belt 2. When the packaging bag has completely passed between the grating signal transmitter 6 and the grating signal receiver 7, the control box 5 will immediately control conveyor belt 1 and conveyor belt 2 to stop running, and start the pushing component 44 to perform the pushing action of the packaging bag. After the packaging bag is pushed to conveyor belt 3 and the lying down action is completed, the control box 5 will receive the message of the push plate 43 resetting, and then control conveyor belt 2 to restart, waiting for the next packaging bag to enter. By installing grating signal transmitter 6 and grating signal receiver 7 on both sides of one end of conveyor belt 1 near conveyor belt 2 respectively, the automatic detection and action triggering of the device can be realized, ensuring that each packaging bag can be pushed in the accurate position, improving the automation accuracy and working stability of the device.

[0042] Reference Figure 4 , Figure 5 and Figure 6The auxiliary lifting assembly 47 includes a lifting gear 471 mounted on the support leg frame 462. The lifting gear 471 is fixedly connected to the rotating end of one of the connecting rods 4631. A limit frame 473 is mounted on the lifting gear 471 and is fixedly connected to the support leg frame 462. A lifting rack 472 is slidably connected to the limit frame 473. The edge of the lifting gear 471 intrudes into the limit frame 473. The lifting gear 471 and the lifting rack 472 are meshed together. A synchronizing element 474 is provided between the push plate 43 and the lifting rack 472.

[0043] When the pushing component 44 drives the pushing plate 43 to swing in the direction of the conveyor belt 3, the pushing plate 43 drives the lifting rack 472 to slide along the length of the limiting frame 473 through the synchronizing member 474. Since the lifting rack 472 is meshed with the lifting gear 471, the sliding of the lifting rack 472 will drive the lifting gear 471 to rotate. The lifting gear 471 drives the connecting rod 4631 fixed to it to rotate synchronously. Then, through the linkage between the two connecting rods 4631 and the support shaft 4632, the limiting rod 45 rotates downward around the support shaft 4632, forming an effective blockage on the upper part of the packaging bag. When the pushing action is completed, the pushing component 44 drives the pushing plate 43 to reset, and the pushing plate 43 drives the lifting rack 472 to slide along the length of the limiting frame 473 through the synchronizing member 474. 2. Sliding along the limiting frame 473, the lifting rack 472 drives the lifting gear 471 to rotate in the opposite direction, and the connecting rod 4631 rotates in the opposite direction accordingly. The limiting rod 45 is lifted upward around the support shaft 4632 and returns to the initial position that does not affect the conveying of the packaging bag, ensuring that the subsequent packaging bags can move smoothly on the conveyor belt 3. Through the meshing transmission of the lifting rack 472 and the lifting gear 471, the limiting frame 473 guides and constrains the lifting rack 472, thereby ensuring the straightness of the lifting rack 472 during the sliding process, and thus accurately controlling the rotation angle of the lifting gear 471, making the action of the connecting rod 4631 driving the limiting rod 45 more stable and reliable, ensuring that the limiting rod 45 presses down to block in time during the pushing of the packaging bag, and quickly lifts up to reset after the pushing is completed.

[0044] Reference Figure 4 , Figure 5 and Figure 6 The synchronizing component 474 includes a synchronizing rod 4742 fixed to one side of the push plate 43, and a synchronizing bar 4741 fixed to one end of the lifting rack 472 near the synchronizing rod 4742. The synchronizing rod 4742 and the synchronizing bar 4741 are slidably connected.

[0045] The synchronizing bar 4741 has a long groove along its length that matches the synchronizing rod 4742. The end of the synchronizing rod 4742 away from the push plate 43 is slidably embedded in the groove. When the push plate 43 swings with the pushing component 44, the synchronizing rod 4742 slides along the groove direction in the groove of the synchronizing bar 4741. At the same time, the side wall of the groove pushes the synchronizing bar 4741 to move along the sliding direction of the lifting rack 472, thereby driving the lifting rack 472 to slide smoothly within the limiting frame 473. This effectively adapts to the displacement difference between the arc swing trajectory of the push plate 43 and the linear motion trajectory of the lifting rack 472. By using the synchronizing rod 4742 and the synchronizing bar 4741 to connect the movement of the push plate and the movement of the lifting rack 472, it is ensured that the movements of the pushing component 44 and the auxiliary lifting component 47 are always precisely synchronized, avoiding the jamming or interference problems caused by the different movement trajectories, and improving the smoothness and coordination of the overall movement of the device.

[0046] Working Principle: In the automated packaging production line for solid powder materials, after the material is filled and sealed to form individual packaging bags, it is conveyed by conveyor belt 2 to one end of conveyor belt 1 near conveyor belt 2. At this time, the packaging bag blocks the infrared beam between the grating signal transmitter 6 and the grating signal receiver 7. The grating signal receiver 7 feeds back the signal to the control box 5, and conveyor belt 1 starts and runs synchronously with conveyor belt 2. After the packaging bag is completely inside conveyor belt 1, the control box 5 stops conveyor belts 1 and 2. Subsequently, the control box 5 starts the pushing component 44, the output end of the electric telescopic rod 4433 extends, pushing the support plate 2 4432 to drive the pushing frame 442 to rotate around the rotating shaft 441. The pushing plate 43 swings towards conveyor belt 3, pushing the bottom of the packaging bag to contact conveyor belt 3. At the same time, the pushing plate 43... 3. The synchronous rod 4742 slides in the groove of the synchronous bar 4741, driving the lifting rack 472 to slide linearly along the limiting frame 473. The lifting rack 472 meshes with the lifting gear 471, causing the lifting gear 471 to drive the connecting rod 4631 to rotate. Then, through the linkage of the support shaft 4632, the limiting rod 45 is pressed down to the front of the upper part of the packaging bag. The conveyor belt 3 starts, and its continuous transmission force drives the lower part of the packaging bag to move. The upper part is blocked by the limiting rod 45 and tilts backward, finally realizing the stable laying down of the packaging bag. After the push is completed, the electric telescopic rod 4433 retracts and drives the push plate 43 to reset. The synchronous component 474 drives the lifting rack 472 to slide in the opposite direction. The lifting gear 471 rotates in the opposite direction to lift the limiting rod 45. The laid-down packaging bag is transported to the subsequent process by the conveyor belt 3, completing the entire auxiliary conveying process.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
