Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery manufacturing, in particular to a full-volume pushing and filling machine for packaging bag materials. Background Art

[0002] In the current industrial packaging process of precision devices such as glass substrates and liquid crystal panels, material loading is a key process that directly determines the final quality and reliability of the product.

[0003] Current industry trends suggest that traditional material loading machinery presents numerous technical challenges that require urgent resolution. Specifically, the following are: 1) Existing loading machinery lacks the necessary drag-reducing design, causing the bottom layer of material to slide directly into the packaging bag during the pushing process. For precision components like glass substrates and LCD panels, which require extremely precise surface finishes, wear and tear is particularly damaging, easily causing fine scratches that directly reduce overall product yield. Furthermore, rigid friction induces electrostatic adsorption, causing wear debris or airborne dust particles to adhere to the component surface, severely compromising the cleanliness standards of dust-free packaging. During the material loading process, excessive friction can cause the packaging bag to shift position or tear, leading to interruptions in the loading and packaging process. 2) Existing loading machinery generally relies on a simple linear push mechanism, lacking scientific phase division and precise planning during the pushing process. This model struggles to provide the correct pushing force and angle for large, irregularly shaped materials, easily causing the material to shift, tilt, or even become stuck during the pushing process. Taking large-size LCD panel packaging as an example, due to the simple pushing action and lack of dynamic adjustment, the panels often accumulate at the bag opening and cannot be pushed completely into the bag, which will inevitably affect the subsequent vacuuming and sealing processes. Therefore, technical personnel are urgently needed to solve this problem. Summary of the Invention

[0004] The purpose of the present invention is to provide a full-volume pushing and filling machine for packaging bags. By switching between the two working modes of the pushing mechanism and combining the lateral translation movement of the material support and drag reduction plate, it aims to achieve the design purpose of complete filling of materials into the packaging bags, so as to solve the problems existing in the prior art.

[0005] The invention relates to a full-volume pushing and filling machine for packaging bags, which is linked with a loading platform and a packaging bag opening machine so that the materials can be completely filled into the packaging bags.

[0006] The full-volume pushing and filling machinery for packaging bags includes:

[0007] frame;

[0008] The pushing mechanism mounted on the frame has two working modes;

[0009] The material support and drag reduction plate is located directly below the frame; when the material support and drag reduction plate is subjected to a side thrust, it performs a lateral translation movement;

[0010] Among them, in the first working mode, the pushing mechanism is mechanically linked with the supporting drag reducing plate to drive the supporting drag reducing plate to perform two forms of lateral translation movement: first, when the loading platform is in the loading position, the pushing mechanism drives the supporting drag reducing plate to move horizontally until it is deeply inside the packaging bag; second, after the material is loaded into the packaging bag and separated from the supporting drag reducing plate, the pushing mechanism drives the supporting drag reducing plate to move horizontally and reset until it is out of the packaging bag;

[0011] In the second working mode, the pushing mechanism releases the mechanical linkage with the material supporting drag reducing plate; the pushing mechanism applies a lateral thrust to the material until the material is transferred from the loading platform to the material supporting drag reducing plate and initially enters the packaging bag until the pushing mechanism critically touches the packaging bag. After that, the pushing mechanism changes its working posture and continues to apply a lateral thrust to the material, and the material continues to penetrate into the packaging bag. During this process, the pushing mechanism penetrates synchronously through the bag opening.

[0012] As a further improvement of the technical solution disclosed in the present invention, the pushing mechanism includes a suspension frame, a circumferential flip frame, a mechanical linkage assembly, an extended-range thrust assembly, a first power unit and a second power unit; the suspension frame is loaded by the frame, and is subjected to the driving force from the first power unit to perform lateral translation movement; the circumferential flip frame is used to simultaneously load the mechanical linkage assembly and the extended-range thrust assembly, which is installed on the suspension frame and is subjected to the rotational torque from the second power unit to perform circumferential flip movement, and working mode one and working mode two can be switched; working mode one: the mechanical linkage assembly and the support The drag reduction plate is mechanically locked. During the work of the first power unit, the circumferential flip frame follows the suspension frame to perform lateral translation movement synchronously. During this period, the material-supporting drag reduction plate performs lateral translation movement due to the force from the mechanical linkage component; Working form two: the working posture of the mechanical linkage component changes to release the mechanical lock with the material-supporting drag reduction plate. During the work of the second power unit, the extended-range side thrust component follows the circumferential flip frame to perform circumferential flipping movement until it is adjusted to a lateral posture. The material placed on the material-supporting drag reduction plate continues to penetrate into the packaging bag due to the side thrust from the extended-range side thrust component.

[0013] As a further improvement of the technical solution disclosed in the present invention, the circumferential turning frame includes a workbench, a rear slewing support and a front slewing support; the workbench serves as an installation base for the mechanical linkage assembly and the extended-range thrust assembly; the rear slewing support and the front slewing support are respectively installed on the rear lower extension leg and the front lower extension leg of the suspension frame, and the two work together to load the workbench; the second power unit selects the following two installation and driving methods: one is that the second power unit drives the workbench by means of the rear slewing support, which is installed and fixed to the rear lower extension leg; the other is that the second power unit drives the workbench by means of the front slewing support, which is installed and fixed to the front lower extension leg.

[0014] As a further improvement of the technical solution disclosed in the present invention, the circumferential flip frame also includes a rotational freedom locking unit; when the workbench is flipped to the expected angle, the circumferential rotational freedom of the workbench is locked through a mechanical limit or braking structure with the assistance of the rotational freedom locking unit.

[0015] As a further improvement of the technical solution disclosed in the present invention, the rotational freedom locking unit includes a polygonal limit plate and a locking power element; the polygonal limit plate is coaxially fixed to the rear slewing support or the front slewing support to form a limit reference that rotates synchronously with the workbench; when the workbench is flipped to a predetermined angle, the locking power element applies a lateral locking force toward the outer contour of the polygonal limit plate.

[0016] As a further improvement of the technical solution disclosed in the present invention, the pushing mechanism also includes a primary pushing plate assembly; the primary pushing plate assembly spans the rear lower extension leg and the front lower extension leg at the same time, and is fixed as a whole in a detachable manner; when the material is completely transferred from the loading platform to the material support drag reduction plate, the primary pushing plate assembly directly applies lateral thrust to the material to initially enter the packaging bag.

[0017] As a further improvement of the technical solution disclosed in the present invention, a first pin hole is formed on the material support and drag reduction plate at a set distance L1 from its left end face; the mechanical linkage assembly includes a first linear motion element and a first locking pin; the first linear motion element is installed on the workbench; the first locking pin penetrates into / out of the first pin hole due to the driving force from the first linear motion element, and the pushing mechanism is able to realize / release the mechanical linkage relationship with the material support and drag reduction plate.

[0018] As a further improvement of the technical solution disclosed in the present invention, the extended-range side thrust assembly includes a second linear motion element and a secondary push plate assembly; the second linear motion element is installed on the workbench; after the extended-range side thrust assembly is flipped to the horizontal posture, the secondary push plate assembly moves toward the material direction and continuously pushes the material laterally under the driving force of the second linear motion element.

[0019] As a further improvement of the technical solution disclosed in the present invention, the full-volume pushing and filling machine for packaging bags also includes a translational motion freedom locking unit; after the material support and drag reduction plate penetrates into the expected position in the packaging bag, the lateral displacement freedom of the material support and drag reduction plate is locked by a mechanical limit or braking structure with the assistance of the translational motion freedom locking unit.

[0020] As a further improvement of the technical solution disclosed in the present invention, a second pin hole is formed on the material support and drag reduction plate at a set distance L2 from its left end face; the translational motion freedom locking unit includes a third linear motion element and a second locking pin; the third linear motion element is arranged directly below the material support and drag reduction plate; the second locking pin penetrates into / out of the second pin hole due to the driving force from the third linear motion element, and the restriction on the lateral translational freedom of the material support and drag reduction plate is realized / removed.

[0021] The material filling steps are as follows:

[0022] S1. Initial preparation stage: Place the loading platform at the loading position, place the material to be loaded on the loading platform, and use the bag opening machine to open the bag mouth to prepare for subsequent material loading;

[0023] S2. Loading the drag reducing plate into the bag: The pushing mechanism is in working mode 1 and is mechanically linked with the drag reducing plate. The pushing mechanism drives the drag reducing plate to perform a lateral translation motion, so that the drag reducing plate slowly penetrates into the packaging bag until it reaches the appropriate position.

[0024] S3. Transferring the material to the support drag reduction plate: The pusher mechanism switches to working mode 2, releases the mechanical linkage with the support drag reduction plate, and returns to its initial position. When the loading platform moves horizontally to align with the support drag reduction plate, the pusher mechanism applies a lateral thrust to the material, pushing the material from the loading platform to the support drag reduction plate, so that the material initially enters the packaging bag;

[0025] S4, material goes deep into the packaging bag: the pushing mechanism continues to apply force to push the material deeper into the packaging bag. When the pushing mechanism critically touches the packaging bag, the pushing mechanism changes its working posture and goes deeper through the bag opening, continuing to push the material to the appropriate position in the packaging bag;

[0026] S5. Reset the material support and drag reduction plate: After the material is loaded into the packaging bag and separated from the material support and drag reduction plate, the pushing mechanism switches to working mode 1 again, and mechanically links with the material support and drag reduction plate to drive the material support and drag reduction plate to perform a lateral translation reset movement, so that the material support and drag reduction plate is removed from the packaging bag, completing a material filling process.

[0027] In practical applications, the packaging bag material full-volume pushing and filling machine disclosed in the present invention can achieve at least the following beneficial technical effects, specifically:

[0028] 1) The unique dual-working design of the pusher mechanism significantly improves the refinement of material loading operations by separating the functions of "supporting drag reduction plate drive" and "material pushing":

[0029] Working mode 1: The material pushing mechanism forms a rigid linkage with the material supporting and drag reducing plate to accurately deliver the material supporting and drag reducing plate to the designated position in the packaging bag, providing a stable and reliable receiving platform for the material. Alternatively, the material supporting and drag reducing plate is dragged from the working position to the initial position to pave the way for subsequent vacuum packaging operations.

[0030] Working mode 2: When the support drag reducing plate is in place, the pushing mechanism immediately releases the linkage relationship with the support drag reducing plate and focuses on the precise pushing of the material. Through a single pushing action, the material is transferred from the loading platform to the support drag reducing plate, and then a secondary extended-range pushing action is used to load the material into place, completely avoiding the occurrence of incomplete material loading and creating ideal conditions for subsequent vacuum packaging.

[0031] 2) A material support and drag reduction plate was introduced for the first time to create a physical barrier between the material and the packaging bag. During the entire filling process, the material relies on the supporting surface of the material support and drag reduction plate to complete the transfer and push until it reaches the desired position in the packaging bag, completely preventing the material from being abraded by direct contact with the inner wall of the packaging bag;

[0032] 3) The drag-reducing plate works in conjunction with the dual-mode pusher mechanism, and in real-time with the loading platform and bag opening mechanism, creating a closed-loop automated packaging system. Throughout the entire loading process, the drag-reducing plate prevents direct contact between the material and the bag, effectively preventing bag tearing or misalignment due to excessive force.

DETAILED DESCRIPTION

[0044] In the description of the present invention, it should be understood that the terms "left", "right", "front", "back", "up", "down", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0045] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 A three-dimensional schematic diagram of the material filling and packaging machine disclosed in the present invention is shown. It can be seen that it is mainly composed of several parts such as a loading platform 1, a packaging bag opening machine 2, a packaging bag material full-volume pushing and filling machine 3 and a packaging platform 4. Through precise timing control and spatial position coordination, each component constructs a complete operation chain from material loading, pushing and filling to final packaging, realizing the automation and efficiency of material packaging.

[0046] The loading platform 1 features a modular design, allowing for flexible adjustment of size based on material specifications. An accompanying infrared sensor detects material placement in real time. If a material is offset or missing, an alarm is triggered and subsequent processes are suspended, ensuring accurate loading. The bag opening mechanism 2 steadily grasps the edge of the bag and opens it to a preset angle, providing reliable opening conditions for material loading. The packaging platform 4, serving as the support base for the final packaging process, securely supports the bag and the loaded material, ensuring a stable packaging process.

[0047] like Figure 2 As shown, the full-volume pushing and filling machine 3 for packaging bag materials mainly consists of several parts, such as a frame 31, a pushing mechanism 32, and a supporting drag-reducing plate 33. Among them, the pushing mechanism 32 is supported by the frame 31 and has two flexibly switchable working modes to adapt to the operation requirements at different stages. The supporting drag-reducing plate 33 is arranged directly below the frame, and its surface is treated with Teflon coating or mirror polishing, which greatly reduces the friction when the material slides. When subjected to side thrust, it can form a close fit with the pushing mechanism 32 through lateral translation. In the material transfer stage, the supporting drag-reducing plate 33 first penetrates into the packaging bag, and its free end rests on the packaging carrier 4 to form a stable support transition; in the filling stage, it supports and guides the material like an "invisible guide rail".

[0048] Form 1: Mechanical linkage mode

[0049] The pusher mechanism 32 and the support and drag reduction plate 33 are linked by a rigid connector. The power of the pusher mechanism 32 is directly converted into lateral translational force for the support and drag reduction plate 33. This design allows for precise control of the motion trajectory of the support and drag reduction plate 33. As the material enters the bag, it is pushed along a strict preset path, avoiding friction with the bag's inner wall that could damage the material. During the reset phase, once the material is fully loaded into the bag and has actively disengaged from the support and drag reduction plate 33, the pusher mechanism 32 drives the support and drag reduction plate 33 to reset along its original path, ensuring smooth removal from the bag and preparation for the next operation.

[0050] Form 2: Independent push mode

[0051] After the pushing mechanism 32 releases the mechanical linkage with the material supporting drag reducing plate 33, the pushing mechanism 32 can independently apply lateral thrust to the material until the material is transferred from the loading platform 1 to the material supporting drag reducing plate 33. When the material initially enters the packaging bag and the pushing mechanism 32 critically touches the packaging bag, the pushing mechanism 32 changes its posture to continue to apply lateral thrust to the material, so that the material can continue to penetrate into the packaging bag, ensuring the integrity of the material filling. In this process, the pushing mechanism 32 synchronously penetrates through the bag opening.

[0052] The material filling steps are as follows:

[0053] S1. Initial preparation stage: Platform 1 moves to the loading position. The operator places the material to be filled in the positioning area of ​​platform 1. Platform 1's infrared sensor immediately detects the material's position and sends a signal after confirming the correct placement. Simultaneously, the bag opening mechanism 2 starts, opening the bag to a size that matches the maximum cross-section of the material, preparing for subsequent filling.

[0054] S2. Inserting the material-supporting drag-reducing plate 33 into the bag: The pushing mechanism 32 is in working mode 1 and is mechanically linked with the material-supporting drag-reducing plate 33. The pushing mechanism 32 drives the material-supporting drag-reducing plate 33 to perform a lateral translation motion, so that the material-supporting drag-reducing plate 33 slowly penetrates into the packaging bag until it reaches the appropriate position.

[0055] S3. Transferring the material to the support and drag reduction plate 33: The pusher mechanism 32 switches to operating mode 2, releasing its mechanical linkage with the support and drag reduction plate 33 and returning to its initial position. Once the platform 1 has moved horizontally to align with the support and drag reduction plate 33, the pusher mechanism 32 applies a lateral thrust to the material, pushing it from the platform 1 onto the support and drag reduction plate 33 and allowing it to initially enter the packaging bag.

[0056] S4. Material goes deeper into the bag: The pushing mechanism 32 continues to apply force to push the material deeper into the bag. When the pushing mechanism 32 critically touches the bag, the pushing mechanism 32 changes its working posture and simultaneously goes deeper through the bag opening, continuing to push the material to the appropriate position in the bag.

[0057] S5. Reset the material-supporting drag-reducing plate 33: After the material is loaded into the packaging bag and is actively separated from the material-supporting drag-reducing plate 33, the pushing mechanism 32 switches to working mode 1 again, and mechanically links with the material-supporting drag-reducing plate 33 to drive the material-supporting drag-reducing plate 33 to perform a lateral translation reset movement, so that the material-supporting drag-reducing plate 33 is removed from the packaging bag, completing a material filling process.

[0058] In actual application, the above-mentioned packaging bag material full-volume pushing and filling machine has achieved the following beneficial technical effects, specifically:

[0059] 1) The unique dual-working design of the pusher mechanism 32 significantly improves the refinement of material loading operations by separating the functions of "driving the material support and drag reduction plate 33" and "pushing the material":

[0060] Working mode 1: The pushing mechanism 32 and the supporting drag reducing plate 33 form a rigid linkage to accurately send the supporting drag reducing plate 33 to the specified position in the packaging bag, providing a stable and reliable support for the material, or dragging the supporting drag reducing plate 33 from the working position to the initial position to pave the way for subsequent vacuum packaging operations;

[0061] Working mode 2: When the material support and drag reduction plate 33 is in place, the pushing mechanism 32 immediately releases the linkage relationship with the material support and drag reduction plate 33 and focuses on the precise pushing of the material. Through a single pushing action, the material is transferred from the loading platform 1 to the material support and drag reduction plate 33, and then a secondary extended-range pushing action is used to load the material into place, completely avoiding the occurrence of incomplete material loading and creating ideal conditions for subsequent vacuum packaging.

[0062] 2) A material support and drag reduction plate 33 is introduced for the first time, creating a physical barrier between the material and the packaging bag. Throughout the filling process, the material relies on the supporting surface of the material support and drag reduction plate 33 to be transferred and pushed until it reaches the desired position in the packaging bag, completely preventing the material from being abraded by direct contact with the inner wall of the packaging bag.

[0063] It's also worth noting that the drag-reducing plate 33 works in conjunction with the dual-mode pushing mechanism 32, and in real-time with the loading platform 1 and the bag-opening mechanism 2, to form a closed-loop automated packaging system. Throughout the material filling process, the drag-reducing plate 33 prevents direct contact between the material and the bag, effectively preventing bag tearing or displacement due to excessive force.

[0064] like Figures 3-5As shown in the figure, the pusher mechanism 32 primarily consists of a suspension frame 321, a circumferential tilting frame 322, a mechanical linkage assembly 323, an extended-range thrust assembly 324, a first power unit 325, and a second power unit 326. The suspension frame 321 is a π-shaped structure, constructed by welding a connecting beam 3211, a rear lower extension leg 3212, and a front lower extension leg 3213. The connecting beam 3211 serves as the foundational support component of the pusher mechanism 32 and rests on the frame 31. When driven by the first power unit 325, the suspension frame 321 performs smooth translational motion in the lateral direction (i.e., the direction in which the material is pushed), providing basic support for the position adjustment of the entire pusher mechanism 32. The circumferential tilting frame 322, supported by the rear lower extension leg 3212 and the front lower extension leg 3213, bears the dual load of the mechanical linkage assembly 323 and the extended-range thrust assembly 324. Under the action of the rotational torque output by the second power unit 326, the circumferential flip frame 322 can perform a circumferential flip motion, which is the key to switching between working mode one and working mode two and changing the working posture of the pushing mechanism 32. The mechanical linkage assembly 323 is used to form a stable mechanical connection with the material support drag reduction plate 33. When it is necessary to drive the material support drag reduction plate 33 to move, the mechanical linkage assembly 323 is precisely docked and locked with the material support drag reduction plate 33 to ensure the rigidity of power transmission; when the form is switched, the mechanical linkage assembly 323 is disconnected from the material support drag reduction plate 33 without affecting the subsequent pushing action. The extended-range side thrust assembly 324 plays a pushing role in working mode two, and can apply side thrust to the material to ensure that the material can be pushed to the appropriate position in the packaging bag.

[0065] Working mode 1: Mechanical linkage mode

[0066] When it is necessary to drive the support drag reducing plate 33 to move, the pushing mechanism 32 switches to this mode:

[0067] The second power unit 326 drives the circumferential turning frame 322 to turn to the initial angle, and the mechanical linkage assembly 323 is aligned with the docking position of the support drag reduction plate 33, and the mechanical connection is completed;

[0068] The first power unit 325 is started to drive the suspension frame 321 to move horizontally, and the circumferential turning frame 322 moves synchronously. The power is transmitted to the material support drag reduction plate 33 through the mechanical linkage component 323, causing it to make the same lateral displacement as the suspension frame 321, thereby achieving the bagging or resetting of the material support drag reduction plate 33.

[0069] Working mode 2: Independent push mode

[0070] When it is necessary to push the material, the pushing mechanism 32 switches to this mode:

[0071] The mechanical linkage assembly 323 releases the mechanical connection with the support drag reduction plate 33;

[0072] The second power unit 326 drives the circumferential turning frame 322 to turn over, so that the extended-range thrust assembly 324 is adjusted to a lateral posture and aligned with the material on the material support and drag reduction plate 33;

[0073] The first power unit 325 drives the suspension frame 321 forward, and the extended-range side thrust assembly 324 moves synchronously, exerting a side thrust on the material, completing the transfer of the material from the loading platform 1 to the material support drag reduction plate 33;

[0074] When the pushing mechanism 32 critically touches the packaging bag, the extended-range side-pushing assembly 324 continues to function to push the material to a suitable position in the packaging bag.

[0075] As one of the preferred designs, Figure 5 As shown in the figure, the circumferential turning frame 322 includes a workbench 3221, a rear slewing support 3222 and a front slewing support 3223. Among them, the workbench 3221 serves as the core bearing component, providing a stable installation basis for the mechanical linkage assembly 323 and the extended-range thrust assembly 324. The rear slewing support 3222 and the front slewing support 3223 jointly serve as the support and rotation mechanism of the workbench 3221, and the two are respectively installed on the rear lower extension leg 3212 and the front lower extension leg 3213. By adopting the above technical solution, the smoothness and accuracy of the circumferential turning movement are ensured, and a solid mechanical foundation is provided for the reliable switching of the two working modes.

[0076] In terms of power transmission, the second power unit 326 offers flexible options for installation and driving. The second power unit 326 is mounted and fixed to the rear lower leg 3212 of the suspension frame 321. Its output shaft is connected to the rotating component of the rear slewing support 3222. By driving the rear slewing support 3222 to rotate, it drives the workbench 3221 to perform circumferential flipping motion. Alternatively, the second power unit 326 can be mounted and fixed to the front lower leg 3213, similarly connecting to the rotating component of the front slewing support 3223 to achieve power transmission, driving the workbench 3221 to flip.

[0077] Depend on Figure 5 、 Figure 6 As can be clearly seen in the figure, based on the above structure, the circumferential turning frame 322 is further equipped with a rotational degree of freedom locking unit 3224. When the workbench 3221 is turned to the desired angle (such as the initial angle required for working mode one or the lateral pushing angle required for working mode two) under the drive of the second power unit 326, the rotational degree of freedom locking unit 3224 will immediately take effect, firmly locking the circumferential rotational degree of freedom of the workbench 3221 through a mechanical limit or braking structure, preventing angular displacement due to force or vibration during subsequent operations, and ensuring that the mechanical linkage assembly 323 or the extended-range thrust assembly 324 always occupies the correct working position.

[0078] As a preferred design, the rotational freedom locking unit 3224 includes a polygonal limit plate 32241 and a locking power element 32242. The polygonal limit plate 32241 is coaxially mounted and fixed to the rear slewing support 3222 or the front slewing support 3223, meaning that it rotates synchronously with the rotation of the workbench 3221, thereby forming a dynamic limit reference. The outer contour of the polygonal limit plate 32241 is polygonal (such as a regular hexagon, a regular octagon, etc.), with each side or each corner corresponding to a predetermined flip angle of the workbench 3221, providing a clear positioning basis for precise locking. The position of the locking power element 32242 corresponds to that of the polygonal limit plate 32241. When the workbench 3221 flips to the predetermined angle, the control system triggers the action of the locking power element 32242, causing its output end to apply a lateral locking force toward the outer contour of the polygonal limit plate 32241. For example, when one edge of the polygonal limiting plate 32241 rotates to align with the locking power element 32242, the output end of the locking power element 32242 extends and tightly abuts against the edge, leveraging the rigidity of the polygonal structure to prevent the polygonal limiting plate 32241 from further rotation, thereby locking the circumferential rotational freedom of the workbench 3221. When the lock needs to be released to allow the workbench 3221 to be flipped again, the locking power element 32242 retracts its output end, releasing the lateral locking force on the polygonal limiting plate 32241, allowing the workbench 3221 to rotate freely under the drive of the second power unit 326.

[0079] As Figure 3 As shown in the figure, the first power unit 325 preferably consists of a linear module 3251 and a slide rail and slider guide assembly 3252, providing power and guidance for the lateral translation of the suspension frame 321. The linear module 3251 integrates a drive motor and transmission structure to convert rotational motion into linear motion, precisely controlling the translation speed and displacement of the suspension frame 321 to meet the power requirements of both operating modes. In the slide rail and slider guide assembly 3252, the slide rail is fixed to the frame 31, and the slider is connected to the suspension frame 321, constraining its motion trajectory and preventing deviation.

[0080] As Figures 3-5As shown in , the second power unit 326 is preferably a rotary cylinder 3261, which provides accurate and efficient power support for the circumferential flipping movement of the circumferential flipping frame 322. The rotary cylinder 3261 can be optionally installed on the rear lower extension leg 3212 and the front lower extension leg 3213, which will not take up too much space and adapt to the layout requirements of the circumferential flipping frame 322. When the working form is switched, the rotary cylinder 3261 drives the circumferential flipping frame 322 to flip quickly to the target angle, and cooperates with the rotational freedom locking unit 3224 to ensure the stability of the posture after switching. Whether it is switching from working form one to working form two, or vice versa, the rotary cylinder 3261 can respond quickly to ensure seamless connection between the two working forms and improve the overall operating efficiency of the pushing mechanism 32.

[0081] like Figure 4 As shown in the figure, the pusher mechanism 32 is further equipped with a primary pusher plate assembly 327. This assembly spans both the rear lower extension leg 3212 and the front lower extension leg 3213 and is removably secured to form a single unit. Once the material has been completely transferred from the loading platform 1 to the drag-reducing plate 33, the primary pusher plate assembly 327 directly applies lateral thrust to the material, assisting its initial entry into the packaging bag. This paves the way for the subsequent deeper push by the extended-range side thruster assembly 324, further enhancing the consistency and stability of material loading.

[0082] like Figure 7 、 Figure 9 As shown in , a distance L1 is set from the left end face of the support drag reducing plate 33, and a first pin hole 331 is formed on the support drag reducing plate 33, which provides a precise positioning reference for the mechanical connection between the mechanical linkage component 323 and the support drag reducing plate 33. Figure 3 、 Figure 5 、 Figure 6 As shown in , the mechanical linkage assembly 323 includes a first linear motion element 3231 and a first locking pin 3232, wherein the first linear motion element 3231 is installed on the workbench 3221. When the pusher mechanism 32 needs to enter working mode one, the first linear motion element 3231 drives the first locking pin 3232 to penetrate into the first pin hole of the material support and drag reduction plate 33. At this time, the pusher mechanism 32 and the material support and drag reduction plate 33 form a stable mechanical linkage relationship, ensuring that when the first power unit 325 is working, the material support and drag reduction plate 33 can follow the suspension frame 321 to synchronously perform lateral translation movement, accurately completing the bag entry or reset action. When it is necessary to switch to working mode two, the first linear motion element 3231 works in the reverse direction, driving the first locking pin 3232 out of the first pin hole 331, and the mechanical linkage relationship between the pusher mechanism 32 and the material support and drag reduction plate 33 is released. At this time, the pushing mechanism 32 can focus on the pushing operation of the material through the cooperation of the single pushing plate assembly 327 and the extended-range side pushing assembly 324, ensuring that after the material is transferred from the loading platform 1 to the material support and drag reduction plate 33, it can smoothly enter the packaging bag and finally complete the full filling.

[0083] like Figures 3 to 6 As shown in , the extended-range side thrust assembly 324 includes a second linear motion element 3241, a secondary push plate assembly 3242, and a guide sleeve guide rod assembly 3243. The three form a stable pushing system, providing accurate and reliable power and guide support for the continued in-depth pushing of materials. The second linear motion element 3241 is installed on the workbench 3221. Its stroke can be flexibly adjusted according to the depth of the packaging bag to meet the filling requirements of materials of different specifications. The secondary push plate assembly 3242 is a component that directly acts on the material and ensures uniform force during pushing. The guide sleeve guide rod assembly 3243 consists of a guide sleeve and a guide rod. The guide sleeve is fixed to the workbench 3221. One end of the guide rod is connected to the secondary push plate assembly 3242, and the other end is passed through the guide sleeve to form a rigid guide structure.

[0084] Once the extended-range thrust assembly 324, driven by the circumferential tilting frame 322, flips to a horizontal position, the second linear motion element 3241 immediately activates, driving the secondary pusher plate assembly 3242 toward the material. Simultaneously, the guide sleeve and guide rod assembly 3243 operate, sliding axially along the guide sleeve to strictly constrain the motion of the secondary pusher plate assembly 3242, preventing it from swaying up and down or side to side during the pushing process. This coordinated action allows the secondary pusher plate assembly 3242 to smoothly approach the material and exert a continuous lateral thrust.

[0085] like Figure 7 、 Figure 8 As shown in the figure, the bag material full-load pushing and filling machine 3 is also equipped with a translational motion freedom locking unit 34. After the material support and drag reduction plate 33 reaches the desired position within the bag, the translational motion freedom locking unit 34 acts to lock the lateral displacement freedom of the material support and drag reduction plate 33 through a mechanical limit or braking structure. This means that during the subsequent material pushing process, the material support and drag reduction plate 33 will not be accidentally displaced due to the reaction force of the material or equipment vibration, and will always remain in the preset support position.

[0086] like Figure 7 、 Figure 9As shown in , a second pin hole 332 is formed on the material support and drag reduction plate 33 at a set distance L2 from its left end face, which provides a positioning reference for the precise locking of the translational motion freedom locking unit 34. The translational motion freedom locking unit 34 includes a third linear motion element 341 and a second locking pin 342. The third linear motion element 341 is arranged directly below the material support and drag reduction plate 33 to ensure that the movement of the second locking pin 342 is precisely controllable. When the material support and drag reduction plate 33 penetrates into the expected position in the packaging bag, the third linear motion element 341 drives the second locking pin 342 to move upward, so that it precisely penetrates into the second pin hole 332. At this time, the lateral translational freedom of the material support and drag reduction plate 33 is firmly restricted, and no accidental displacement can occur. When the material is loaded and separated from the material supporting and drag reducing plate 33, the third linear motion element 341 drives the second locking pin 342 to move downward, so that it disengages from the second pin hole 332. The lateral translation freedom restriction of the material supporting and drag reducing plate 33 is then released, and it can be smoothly reset under the drive of the pushing mechanism 32, preparing for the next loading operation.
