Description

Technical Field

[0001] This invention belongs to the field of packaging equipment technology, and in particular relates to a sorting machine. Background Technology

[0002] In automated packaging production lines, bagged materials from the front-end processes typically need to be collected, their orientation adjusted, and arranged into standardized arrays so that the back-end case packing machines or sealing equipment can perform batch case packing or wrapping.

[0003] In existing technologies, front-end feeding typically involves high-frequency, continuous conveying, while the rear-end matrix alignment is accomplished through intermittent longitudinal batch pushing. Traditional alignment equipment often uses a fixed receiving platform with a pusher cylinder for simple action handover. This lack of dynamic follow-up and transition handover mechanism can easily lead to material congestion, stacking, or jamming by the pusher plate during high-speed production, causing production line downtime. Furthermore, the bag material often has uneven thickness distribution. When a large-area, wide pusher plate pushes the entire group of bags to slide on a flat surface, force imbalance can easily occur, causing deflection to both sides or overlapping, disrupting the regularity of the array. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a aligning machine with high alignment accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This aligning machine includes a base frame, on which a clustering plate is provided. A longitudinally extending central long guide rib is provided at the center of the clustering plate. Side guide rib groups are provided on the left and right sides of the central long guide rib. The side guide rib groups consist of long guide ribs and short guide ribs arranged alternately in a transverse direction. The feed ends of the central long guide rib, the long guide ribs, and the short guide ribs are flush. The long guide ribs extend obliquely towards the center line of the clustering plate, and both the long guide ribs and the central long guide rib extend towards the discharge end of the clustering plate. The outermost long guide rib is flush with the edge of the discharge end of the clustering plate. The central long guide rib and the remaining long guide ribs terminate before reaching the edge of the discharge end of the clustering plate.

[0006] The feeding end of the clustering plate is provided with an annular feeding mechanism for laterally conveying the bags. A follow-up guide plate mechanism is provided between the annular feeding mechanism and the clustering plate. The follow-up guide plate mechanism has several first guide grooves extending radially in a fan shape. The follow-up guide plate can be laterally displaced to achieve dynamic follow-up alignment, which is used to smoothly receive and guide the bags output by the annular feeding mechanism to the clustering plate. A longitudinal pushing mechanism is provided above the base frame. The longitudinal pushing mechanism is used to push the bags on the annular feeding mechanism to the clustering plate via the follow-up guide plate mechanism and remove them from its discharge end.

[0007] By setting up a follow-up guide plate mechanism that can perform lateral dynamic follow-up alignment, the motion rhythm of continuous lateral feeding at the front end can be connected with the batch intermittent pushing action at the rear end. At the same time, in conjunction with the radial guide rib array composed of central long guide ribs, inclined long guide ribs and alternating short guide ribs on the clustering and gathering plate, the bag body is made to follow the rib path trajectory from dispersed to neatly gather towards the center during the longitudinal pushing process. This solves the deflection, skewness and overlapping phenomena that easily occur when the flexible bag body is pushed over a long distance, and achieves high alignment and regularity under high-speed feeding conditions.

[0008] In the aforementioned alignment machine, the extension length of the central long guide rib is less than the extension length of the longest guide rib closest to the central long guide rib in the side guide rib group; the length of the short guide ribs increases sequentially from the center of the bundling plate to the side edge; in the side guide rib group, the extension length of the long guide ribs is arranged in an alternating pattern of long and short intervals from the inside to the outside of the bundling plate. This stepped guide rib length design creates a channel for gradually releasing frictional stress from the outside to the inside, causing staggered timing of end separation of multiple rows of bags during the pushing process, preventing multiple rows of material from simultaneously squeezing the edge of the discharge port, resulting in smoother material discharge.

[0009] In the aforementioned aligning machine, the follower guide plate mechanism includes the follower guide plate. The follower guide plate has a follower plate lateral movement unit at its bottom and a vertically lifting receiving baffle at its discharge end. A receiving baffle lifting groove is located at the bottom of the discharge end of the follower guide plate. The receiving baffle is connected to the follower guide plate via the receiving baffle lifting unit. The vertically lifting receiving baffle can sink or rise when pushed by the longitudinal pushing mechanism, thus coordinating with the production cycle to temporarily retain the material within the follower guide plate or allow the material to directly enter the subsequent bundling and gathering plate. The structure is compact and has a low interference rate.

[0010] In the aforementioned aligning machine, the annular feeding mechanism includes a frame, on which a transversely rotating annular circulating conveyor component is mounted. Several material seats are distributed along the direction of the annular circulating conveyor component, and each material seat has a longitudinally penetrating feeding trough with its opening facing away from the annular circulating conveyor component. One end of the annular circulating conveyor component has a feeding station, and the feeding station is equipped with a feeding baffle located at the material seat outlet end to prevent the bag from detaching when it enters the longitudinal feeding trough longitudinally. The feeding baffle is mounted on the frame. The open feeding trough facing away from the conveyor belt, combined with the fixed feeding baffle, effectively counteracts the forward inertia of the material during high-speed feeding, preventing material from flying out.

[0011] In the above-mentioned aligning machine, the feeding station is also equipped with an arc-shaped baffle connected to the frame. The inner arc surface of the arc baffle is adapted to the running trajectory of the material seat, and is used to prevent the bag from coming out radially outward when the bag body flips and changes position along the arc trajectory with the material seat.

[0012] The arc-shaped baffle, along the operating direction of the annular circulating conveyor component, sequentially includes a continuous plate segment and a guide strip segment;

[0013] The continuous plate segment is set in accordance with the feeding station. Its inner arc surface is a smooth surface without grooves, which is used to prevent jamming during bag feeding and initial repositioning. The guide strip segment is composed of multiple longitudinally distributed and parallelly spaced arc-shaped guide strips, and hollow grooves are formed between adjacent arc-shaped guide strips for weight reduction.

[0014] The arc-shaped baffle is connected to the frame via a front arc-shaped mounting base, and the feed baffle is also connected to the frame via the same front arc-shaped mounting base. A second feed baffle is also provided on the front arc-shaped mounting base between the feed baffle and the arc-shaped baffle. The combination of the continuous smooth section and the hollowed-out guide strip reduces the overall weight of the components while maintaining the anti-detachment function, thus enhancing overall durability.

[0015] In the aforementioned aligning machine, shrink plates are also provided above the feeding station, respectively positioned on both sides of the annular circulating conveyor component. Along the operating direction of the annular circulating conveyor component, the longitudinal distance between the inner surfaces of the two shrink plates gradually decreases. These shrink plates abut against the ends of the bags as they move forward with the material seat, pushing and shifting the bags in the longitudinal feeding trough towards the center or a position slightly off-center towards the discharge end, and preventing the bags from completely approaching the edge of the discharge end. Through the gradually shrinking plate design, the running power in front of the conveyor belt can be used to automatically center and push the bags, standardizing the initial posture of the material before it enters the follow-up guide plate.

[0016] In the aforementioned alignment machine, the annular feeding mechanism is equipped with a clip feeding mechanism at its feed end. The clip feeding mechanism includes a frame, on which a feeding conveyor belt is mounted. One side of the feeding conveyor belt has an inner feed baffle extending from the feed end to the discharge end. An outer feed baffle is located on the outer side of the feed end of the feeding conveyor belt, and an outer discharge baffle is located on the outer side of the discharge end of the feeding conveyor belt. A feeding detection module is provided at the feed end of the feeding conveyor belt. The outer feed baffle and the outer discharge baffle... A rejection receiving station is provided between the baffles. At least one rejection port is provided on the inner feed baffle on the opposite side of the rejection receiving station. A rejection mechanism is provided on the rejection port for laterally rejecting the bag body on the feed conveyor belt and moving it out from the rejection receiving station side. An upper pressing conveyor belt is provided between the outer discharge baffle and the inner feed baffle, which is located above the feed conveyor belt. A shaping feeding channel is formed between the feed conveyor belt and the upper pressing conveyor belt. The discharge end of the shaping feeding channel is provided with a discharge guide structure.

[0017] By combining the feeding detection module with the rejection mechanism, timely rejection of defective products is achieved online. At the same time, the upper pressing conveyor belt and the feeding conveyor belt work together to form a shaping feeding channel, which realizes the upper and lower clamping and stable shaping of materials during the conveying process, effectively avoiding the tilting and overturning of materials during the process, and improving the stability and continuity of the overall conveying.

[0018] In the above-mentioned aligning machine, the upper pressing conveyor belt includes an upper conveyor belt frame, on which an annular upper pressing belt and an upper pressing belt drive assembly are provided; between the upper conveyor belt frame and the frame body, an upper pressing belt adaptive floating assembly for automatically adjusting the spacing according to the bag thickness is provided, the upper pressing belt adaptive floating assembly includes a rotating shaft and a buffer limiting structure, the side of the upper conveyor belt frame near the feeding end is hinged to the frame body through the rotating shaft, and the side of the upper conveyor belt frame near the discharging end is provided with the buffer limiting structure between itself and the frame body;

[0019] The buffer limiting structure includes a stop fixed on the upper conveyor belt frame and a lower ramp set on the frame;

[0020] A buffer and shock absorber is provided between the stop block and the slope surface of the lower incline, and the buffer and shock absorber is connected to the stop block by an adjusting bolt. The slope surface of the lower incline gradually slopes upward from the feed end to the discharge end, and the axis of the adjusting bolt is perpendicular to the slope surface of the lower incline. Through the cooperation of the slope surface and the buffer and shock absorber, the vibration generated when the upper conveyor belt frame floats can be effectively buffered, enhancing the stability of the dynamic adjustment process of the spacing.

[0021] In the aforementioned alignment machine, the discharge guiding structure includes an upper discharge guide plate and a lower discharge guide plate disposed at the discharge end of the forming feeding channel. A discharge guiding channel is formed between the upper and lower discharge guide plates, and the vertical spacing of the discharge guiding channel gradually decreases along the discharge direction. The upper and lower discharge guide plates, facing the discharge guiding channel, are sequentially provided with an inclined guide surface and a parallel surface along the material conveying direction. The spacing between the inclined guide surfaces on both sides gradually decreases along the discharge direction, and the parallel surfaces on both sides are parallel to each other and parallel to the conveying axis of the feeding conveyor belt. The inclined guide surfaces serve to smooth the transition and correct deviations, while the parallel surfaces are used to stabilize and straighten the final discharge posture of the material, ensuring that the material enters the next process in a standard posture.

[0022] In the above-mentioned aligning machine, the longitudinal pushing mechanism includes a top frame, on which a linear drive module extending longitudinally is provided. The linear drive module is provided with a first drive slider and a second drive slider. The first drive slider is connected to a first push plate through an XYZ moving mechanism. A pressure plate made of elastic material is suspended in front of the first push plate in the pushing direction. The second drive slider is provided with a second double guide column lifting assembly. The output end of the second double guide column lifting assembly is connected to a shrink push plate.

[0023] And / or, the discharge end of the clustering plate is provided with a discharge mechanism, the discharge mechanism includes a discharge tray, and the two sides of the bearing surface of the discharge tray are respectively provided with side baffles, and the two side baffles form a discharge channel that gradually shrinks from the feeding end.

[0024] The bottom of the discharge tray is connected to the discharge plate transverse moving unit, and a discharge pusher plate that can move along the longitudinal discharge channel is provided above the discharge channel. The discharge pusher plate is connected to the discharge plate transverse moving unit through a discharge pushing mechanism.

[0025] The discharge end of the discharge tray is equipped with a discharge baffle that can be lifted vertically. The discharge baffle lifting port is provided on the discharge end of the discharge tray. The discharge baffle is connected to the discharge plate transverse movement unit through the discharge baffle lifting unit.

[0026] The drive features an independent control design, supporting the main push plate's elastic pressing and pushing, and the auxiliary push plate and discharge push plate's alternating relay or front and rear clamping push, allowing for a high degree of freedom in the arrangement of pushing actions.

[0027] Compared with existing technologies, the advantages of this aligning machine are: 1. It features a follow-up guiding mechanism, resulting in high production efficiency. 2. It has a clustering and gathering structure, ensuring high array regularity. 3. It provides smooth conveying, effectively preventing material compression damage and jamming. 4. It has a guiding structure, ensuring precise and stable material posture. 5. The mechanism is highly versatile and easy to maintain. Attached Figure Description

[0049] like Figures 1 to 20 As shown, this aligner includes a base frame 1, on which a clustering plate 2 is provided. A longitudinally extending central guide rib 21 is provided at the center of the clustering plate 2. Side guide rib groups 22 are provided on the left and right sides of the central guide rib 21. The side guide rib groups 22 include long guide ribs 23 and short guide ribs 24 arranged alternately in the transverse direction. The feed ends of the central guide rib 21, long guide ribs 23 and short guide ribs 24 are flush. The long guide rib 23 extends obliquely towards the center line of the clustering plate 2, and both the long guide rib 23 and the central guide rib 21 extend towards the discharge end of the clustering plate 2. The outermost long guide rib 23 is flush with the edge of the discharge end of the clustering plate 2. The central guide rib 21 and the remaining long guide ribs 23 terminate before reaching the edge of the discharge end of the clustering plate 2.

[0050] The feeding end of the clustering plate 2 is provided with an annular feeding mechanism 3 for transversely conveying the bag body. A follow-up guide plate mechanism 4 is provided between the annular feeding mechanism 3 and the clustering plate 2. The follow-up guide plate 42 of the follow-up guide plate mechanism 4 is provided with a number of first guide grooves 41 extending in a fan-shaped radial pattern. The follow-up guide plate 42 can be transversely displaced to achieve dynamic follow-up alignment, which is used to smoothly receive and guide the bag body output by the annular feeding mechanism 3 to the clustering plate 2.

[0051] A longitudinal pushing mechanism 5 is provided above the base frame 1. The longitudinal pushing mechanism 5 is used to push the bag body on the annular feeding mechanism 3 to the bundle gathering plate 2 via the follow-up guide plate mechanism 4 and remove it from its discharge end.

[0052] In this embodiment, when the front-end annular feeding mechanism 3 continuously transports the bags laterally to the handover area, the follower guide plate 42 of the follower guide plate mechanism 4 performs real-time lateral dynamic tracking and alignment, enabling the bags output by the annular feeding mechanism 3 to smoothly enter the first guide groove 41, avoiding interference or leakage between continuous high-speed feeding and intermittent pushing by subsequent mechanisms. After the handover is completed, the longitudinal pushing mechanism 5 pushes the entire group of bags on the follower guide plate 42 longitudinally onto the clustering plate 2. During the pushing process, the bottom of the bag moves along the guide path formed by the central long guide rib 21, the inclined long guide rib 23, and the short guide rib 24; since the long guide ribs 23 on the sides are all inclined and converged towards the center, the bags that were originally arranged laterally are forcibly gathered towards the center when sliding forward, finally forming a compact and standardized array and being moved out from the discharge end. This achieves the effect of avoiding deflection, skewness, and overlapping of flexible bags during long-distance pushing.

[0053] More specifically, the extension length of the central long guide rib 21 is less than the extension length of the long guide rib 23 closest to the central long guide rib 21 in the side guide rib group 22; the length of the short guide rib 24 increases sequentially from the center of the clustering plate 2 to the side edge; in the side guide rib group 22, the extension length of the long guide rib 23 is arranged alternately with one long and one short in the direction from the inside to the outside of the clustering plate 2.

[0054] More specifically, the follower guide plate mechanism 4 includes a follower guide plate 42, a follower plate transverse movement unit 43 at the bottom of the follower guide plate 42, a receiving baffle 441 that can be vertically lifted at the discharge end of the follower guide plate 42, a receiving baffle lifting groove 421 at the bottom of the discharge end of the follower guide plate 42, and the receiving baffle 441 is connected to the follower guide plate 42 through the receiving baffle lifting unit 44.

[0055] In this embodiment, the follower plate transverse movement unit 43 includes a follower linear module 431, and a guide plate mounting plate 432 is provided on the slider of the follower linear module 431. The receiving baffle lifting unit 44 includes a receiving baffle lifting motor 442 fixedly connected to the guide plate mounting plate 432, and the output end of the receiving baffle 441 is connected to the receiving baffle.

[0056] like Figures 4 to 8 As shown, the annular feeding mechanism 3 includes a frame 31, on which a transversely rotating annular circulating conveying component 32 is provided. On the annular circulating conveying component 32, there are several material seats 33 distributed along its operating direction. On the material seats 33, there are longitudinally penetrating longitudinal feeding grooves 331, and the openings of the longitudinal feeding grooves 331 are away from the annular circulating conveying component 32. One end of the annular circulating conveying component 32 is provided with a feeding station 321. The feeding station 321 is provided with a feeding baffle 34 located at the discharge end of the material seat 33 to prevent the bag from falling out when it enters the longitudinal feeding groove 331 longitudinally. The feeding baffle 34 is provided on the frame 31.

[0057] More specifically, the feeding station 321 is also equipped with an arc-shaped baffle 35 connected to the frame 31. The inner arc surface of the arc-shaped baffle 35 is adapted to the running trajectory of the material seat 33, and is used to prevent the bag from coming out radially outward when the bag body flips and changes position along the arc trajectory with the material seat 33. The arc-shaped baffle 35 includes a continuous plate segment 351 and a guide strip segment 352 in sequence along the running direction of the annular circulating conveyor component 32. The continuous plate segment 351 is set corresponding to the feeding station 321, and its inner arc surface is a smooth surface without grooves, used for To prevent jamming during bag feeding and initial repositioning; the guide bar segment 352 is composed of multiple longitudinally distributed and parallelly spaced arc-shaped guide bars 353, with hollow grooves 354 formed between adjacent arc-shaped guide bars 353 for weight reduction; the arc-shaped baffle 35 is connected to the frame 31 through the front arc-shaped mounting seat 36, and the feed baffle 34 is also connected to the frame 31 through the front arc-shaped mounting seat 36. A second feed baffle 361 is also provided on the front arc-shaped mounting seat 36 between the feed baffle 34 and the arc-shaped baffle 35.

[0058] like Figure 5 and 6 As shown, the second feed baffle 361 is disposed on the side of the arc-shaped baffle 35 located at the discharge end of the material seat 33, and extends into the height gap 342. A height gap 342 is provided between the arc-shaped baffle 35 and the material seat 33, and a height gap adjustment component 341 is provided between the arc-shaped baffle 35 and the front arc-shaped mounting seat 36.

[0059] In this embodiment, the height gap adjustment component 341 includes an arc-shaped baffle connecting plate connected to the front arc-shaped mounting base 36 and integrally connected with the arc-shaped baffle 35. The arc-shaped baffle connecting plate is provided with a height gap adjustment hole extending along the height direction of the height gap 342. The height gap adjustment hole is provided with a bolt for adjusting and fixing the relative position of the front arc-shaped mounting base 36 and the arc-shaped baffle 35.

[0060] More specifically, above the feeding station 321, there are also shrink plates 322 respectively set on both sides of the annular circulating conveyor 32. Along the running direction of the annular circulating conveyor 32, the longitudinal distance between the inner sides of the two shrink plates 322 gradually decreases. They are used to abut against the end of the bag when the bag moves forward with the material seat 33, so as to push and move the bag in the longitudinal feeding trough 331 towards the middle or the middle towards the discharge end, and restrict the bag so that it does not get completely close to the edge of the discharge end.

[0061] In this embodiment, the shrink plate 322 is connected to the frame 31 via a lateral spacing adjustment assembly 323. The lateral spacing adjustment assembly 323 includes a shrink plate connecting seat connected to the frame 31 and adjustablely connected to the shrink plate 322. The shrink plate 322 is provided with a lateral spacing adjustment hole extending along the length direction of the feeding trough 31, and bolts are provided in the lateral spacing adjustment hole to adjust and fix the relative position of the frame 31 and the shrink plate 322.

[0062] like Figure 7 As shown, guide grooves 332 are provided on both sides of the feed end of the longitudinal feed trough 331. The longitudinal feed trough 331 is provided with two drag-reducing protrusions 334 extending laterally and one drag-reducing groove 333 extending longitudinally; the drag-reducing protrusions 334 and the drag-reducing groove 333 are distributed along the height direction of the longitudinal feed trough 331.

[0063] In this embodiment, the drag-reducing groove 333 is disposed between the two drag-reducing protrusions 334.

[0064] like Figure 8 As shown, the annular circulating conveyor component 32 includes a drive wheel 324, a driven wheel 325, and an annular chain plate 326. The drive wheel 324 is connected to the drive wheel drive unit 328, and each chain connecting plate 327 of the annular chain plate 326 is provided with a material seat 33.

[0065] In this embodiment, both the driving wheel 324 and the driven wheel 325 are sprockets. The annular chain plate 326 includes two transmission chains that surround and mesh with the driving wheel 324 and the driven wheel 325 at both ends. The transmission chains are arranged parallel to each other along the width direction of the annular circulating conveying member 32. The links of the two transmission chains are in phase, and the links of the same sequence on different transmission chains are on the same transverse straight line in the conveying direction.

The second gap 553 is greater than the first gap 552.

[0092] In this embodiment, the pressure plate 55 can be made of a high-toughness elastic material such as polyurethane or silicone rubber. Because the upper first spacing 552 is smaller and the lower second spacing 553 is larger, a gradually narrowing force-bearing space is formed between the pressure plate 55 and the first pusher plate 54. During the pushing operation, the first pusher plate 54 provides a forward lateral thrust, while the suspended pressure plate 55, upon contact with the material, conforms to the shape of the material's upper surface, applying a flexible downward pressing force. This ensures the stability of the material's posture during the conveying process.

[0093] like Figure 18 and 19As shown, the pressure plate 55 is fixed on the pressure plate bracket 554, and the pressure plate bracket 554 is connected to the first push plate 54 through two sets of first swing adjustment structures 541.

[0104] like Figure 1 and 2 As shown, the discharge end of the clustering plate 2 is provided with a discharge mechanism 7. The discharge mechanism 7 includes a discharge tray 71. Side baffles 72 are provided on both sides of the bearing surface of the discharge tray 71. The two side baffles 72 form a discharge channel 73 that gradually narrows from the feeding end.

[0105] The bottom of the discharge tray 71 is connected to the discharge plate transverse moving unit 74. Above the discharge channel 73, there is a discharge pusher 761 that can move along the longitudinal discharge channel 73. The discharge pusher 761 is connected to the discharge plate transverse moving unit 74 through the discharge pushing mechanism 76.

[0106] The discharge end of the discharge tray 71 is provided with a discharge baffle 751 that can be lifted vertically. The discharge end of the discharge tray 71 is provided with a discharge baffle lifting port 711. The discharge baffle 751 is connected to the discharge plate transverse movement unit 74 through the discharge baffle lifting unit 75.

[0107] In this embodiment, the discharge plate lateral movement unit 74 includes a discharge plate lateral movement linear module 741, a discharge plate mounting plate 742 connected to the slider of the discharge plate lateral movement linear module 741, and the bottom of the discharge support plate 71 connected to the discharge plate mounting plate 742; the discharge pushing mechanism 76 includes a discharge pushing linear module 762, which is connected to the discharge plate mounting plate 742 via a bracket; the discharge baffle lifting unit 75 includes a discharge baffle lifting motor 752, which is connected to the discharge plate mounting plate 742.

[0108] In this embodiment, the discharge plate horizontal linear module 741, the discharge pushing linear module 762, and the discharge baffle lifting motor 752 are all existing technologies, and their specific structures will not be described in detail.

[0109] The working principle of this embodiment is as follows: before the alignment operation, the operator can pre-adjust the equipment according to the size and shape of the bag: loosen the adjusting bolt in the arc-shaped adjusting hole 544 to allow the swing rod 543 to rotate around the swing hinge seat 542, thereby adjusting the tilt angle of the pressure plate 55; loosen the adjusting bolt in the adjusting hole 555 to allow the pressure plate bracket 554 to slide along the adjusting hole 555, thereby adjusting the extension depth of the pressure plate 55; after adjustment, tighten the adjusting bolt. At the same time, the bolts of the transverse spacing adjusting component 323 and the height gap adjusting component 341 can be adjusted according to the bag specifications to change the spacing of the shrink plate 322 and the height gap 342 of the arc-shaped baffle 35 to adapt to production needs.

[0110] First, the feed belt drive assembly 621 drives the feed conveyor belt 62 forward, and the upper pressure belt drive assembly 68 drives the upper pressure belt 652 to operate synchronously. The material first smoothly enters the feed conveyor belt 62 through the figure-eight opening formed by the inlet ends of the inner feed baffle 611 and the outer feed baffle 612. The laser sensor in the feed detection module 625 detects the material status in real time. If a defective product is detected, the air supply unit 644 controls the air nozzle 643 to instantly spray high-pressure gas, blowing the defective product laterally and causing it to fall into the receiving outlet 649 of the rejection receiving rack 648 for discharge. If a good product is detected, the material continues to move forward and is smoothly guided by the guide plate 614 into the shaping feeding channel 66. The shaft 691 at the feed end of the upper conveyor belt frame 651 is finely adjusted within the shaft floating hole 618. At the discharge end, the upper pressure belt 652 is adaptively floated by the buffer shock absorber 695 along the lower slope 694, which, together with the back pad 654, maintains a stable pressing and shaping force on the bag. The material is finally accurately output after being gradually corrected by the inclined guide surface 661 and the parallel surface 662, and the status is confirmed by the sensor at the discharge detection port 663.

[0111] Subsequently, the drive unit 328 operates, driving the material seat 33 to continuously circulate along the annular conveyor component 32 via the ring chain plate 326. The shaped bag is pushed at high speed from the front end into the longitudinal feeding trough 331 of the feeding station 321. The guide chute 332 acts as a funnel-shaped guide, while the drag-reducing protrusion 334 and drag-reducing groove 333 significantly reduce friction. After entering, the bag slides due to inertia and abuts against the feeding baffle 34 and the second feeding baffle 361, physically limiting it to prevent it from coming out. As the material seat 33 moves forward, both ends of the bag enter between the shrink plates 322, and the bag is gently pushed and moved towards the center using the gradually decreasing spacing, achieving online correction during the conveying process. When the end curves overturn, the outer side of the bag abuts against the arc-shaped baffle 35, and the continuous plate segment 351 and the smooth arc-shaped guide strip 353 provide anti-coming-out guidance, ensuring a safe transition.

[0112] When the front-end annular feeding mechanism 3 continuously transports the bag body laterally to the discharge handover area, the follower plate lateral movement unit 43 drives the follower guide plate 42 to perform real-time lateral dynamic tracking and alignment, so that the bag body output by the annular feeding mechanism 3 can smoothly slide into the first guide groove 41. This dynamic follow-up mechanism perfectly absorbs the rhythm difference between continuous high-speed feeding and subsequent intermittent pushing, avoiding interference or leakage. At the same time, the receiving baffle lifting unit 44 controls the lifting and lowering of the receiving baffle 441 to provide longitudinal obstruction during receiving.

[0113] After the handover is completed, the longitudinal pushing mechanism 5 is activated. In the Y direction, the linear drive module 52 drives the first drive slider 521 to move horizontally; in the X direction, the traction drive motor 571 drives the transmission belt 534 to rotate via the driver pulley 572, drive transmission belt 575, drive shaft 532 and pulley assembly 533, and pulley 533, traction the transverse slider 583 to slide along the transverse guide rail 582; in the Z direction, the lifting drive motor 576 drives the first pusher plate 54 to descend smoothly along the linear bearing 594. The XYZ moving mechanism 511 drives the first pusher plate 54 to accurately position itself behind the follower guide plate 42 to perform the pushing action.

[0114] During this process, the first pusher plate 54 applies a forward pushing force to the side of the bag body. The pressure plate 55 hanging in front of it undergoes elastic deformation after contacting the material to conform to the material's contour, applying a downward flexible pressing force, which completely suppresses the tendency of the bag body to tilt or roll upward at the moment of being pushed. The first pusher plate 54 pushes the entire group of bags longitudinally onto the bundling and gathering plate 2. During the sliding process, the bottom of the bag body moves along the central long guide rib 21, the inclined long guide rib 23, and the short guide rib 24. The inclined long guide rib 23 forcibly gathers the originally horizontally dispersed bags towards the center, ultimately forming a compact, parallel, and standardized array at the discharge end, achieving high-precision alignment, and finally discharging the bags through the discharge mechanism 7 into subsequent processes.

[0115] The retractable pusher plate 561 of the second pusher assembly 6 can be independently positioned by the second drive slider 522 and lowered by the second lifting drive motor 563 to cooperate with the first pusher plate 54 to clamp and guide the material or push it in relay; and to rise to avoid obstacles when not in operation.
