Description

Technical Field

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

[0002] After items such as tissues and diapers are sealed in outer plastic, multiple finished products need to be packaged together. Currently, the packaging method typically uses cardboard boxes, transferring the finished products one by one or in rows into the boxes for stacking. However, due to the high cost of cardboard box packaging, some packaging methods, in order to reduce overall costs, involve stacking multiple finished products and then transferring the entire stack to a sealing device for final packaging. This process requires temporary storage and transfer of the stacked materials, making it difficult to improve overall stacking and packaging efficiency. Therefore, there is an urgent need for equipment that can stack and package materials more efficiently. Summary of the Invention

[0003] The purpose of this invention is to provide a material stacking and baling machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this invention is:

[0005] Material stacking and baling machines include:

[0006] Stacking mechanism, having pallets for stacking materials;

[0007] A conveying mechanism includes a conveying component and a pressing component, wherein the conveying component is located on one side of the pallet, and the pressing component can move downward toward or upward toward the conveying component;

[0008] The discharge assembly has a discharge plate that can move back and forth between the pallet and the conveying assembly;

[0009] A vertical sealing assembly is located between the pallet and the conveying assembly. The vertical sealing assembly includes an upper vertical sealing head and a lower vertical sealing head that can move up and down respectively. A cutter is provided inside the upper vertical sealing head.

[0010] A film feeding assembly can feed film between the pallet and the conveying assembly;

[0011] The side sealing assembly includes upper and lower side seals located on both sides of the conveying assembly, and the two upper and two lower side seals can move up and down respectively.

[0012] This technical solution has at least the following beneficial effects: After the materials are stacked on the pallet, the film feeding assembly can feed the packaging film between the pallet and the conveying assembly, so that the packaging film will spread out between the pallet and the conveying assembly. The discharge plate in the discharge assembly moves from the pallet to the conveying assembly, pushing the material on the pallet to the conveying assembly. During this process, one side of the stacked material abuts against the packaging film, so that the packaging film wraps around the upper and lower sides of the stacked material. Then, the pressing assembly moves closer to the conveying assembly, pressing the stacked material and the packaging film together in the vertical direction, so that the packaging film fits the stacked material more tightly. Then, the upper vertical sealing head in the vertical sealing assembly moves downward and the lower vertical sealing head moves upward, using the upper and lower vertical sealing heads to wrap the material. On the other side of the film, heat sealing is performed from top to bottom. Using the cutter inside the upper vertical sealing head, the middle position of the heat-sealed packaging film is cut, separating the packaging film wrapped around the outside of the stacked material. This leaves space for the next packaging of the stacked material, forming a continuous packaging film. After the vertical sealing component completes the sealing of one side of the packaging film, the side sealing component seals both sides of the stacked material. The two upper side sealing heads move downwards and the two lower side sealing heads move upwards, pressing and heat-sealing the portion of the packaging film on both sides of the stacked material. This completes the packaging and sealing of the material from all sides. In this way, the material after stacking can be directly wrapped and sealed, saving the steps of material transfer and greatly improving the efficiency of material stacking and packaging.

[0013] As a further improvement to the above technical solution, the conveying assembly includes a first conveyor and a second conveyor arranged sequentially in a direction away from the pallet, and the pressing assembly includes a third conveyor located above the first conveyor and a fourth conveyor located above the second conveyor. The third conveyor can move downward toward or upward away from the first conveyor, and the fourth conveyor can move downward toward or upward away from the second conveyor. The two upper end caps and the two lower end caps are respectively located on both sides of the second conveyor.

[0014] As a further improvement to the above technical solution, the conveying width of the second conveyor is smaller than that of the first conveyor, and the two lower end caps are located at the bottom of the stroke and are close to the two sides of the second conveyor, and directly opposite the first conveyor.

[0015] As a further improvement to the above technical solution, the conveying assembly further includes two fifth conveyors, one end of which is rotatably connected to the two ends of the first conveyor near the second conveyor. The two fifth conveyors can be rotated upward to be flush with the first conveyor or rotated downward away from the first conveyor. The two upper end caps and the two lower end caps can move in the direction of approaching or moving away from the second conveyor.

[0016] As a further improvement to the above technical solution, the side sealing assembly also includes a connecting frame located beside the two upper side caps, with multiple vacuum suction cups connected to the two connecting frames respectively, and the two connecting frames can be tilted downwards toward or upwards away from the conveying assembly.

[0017] As a further improvement to the above technical solution, the stacking mechanism includes:

[0018] The transfer station is located on the side of the pallet away from the conveying assembly, with the side of the transfer station away from the pallet as the inlet side and the other side as the outlet side. The pallet can be retracted downward or protruded upward from the outlet side.

[0019] A feeding assembly is located on the inlet side, and the feeding assembly has a feeding end that moves toward the transfer table;

[0020] A stacking assembly having a material support member movable above the pallet or movable to be offset from the pallet;

[0021] The first pusher assembly has a first pusher plate that can move back and forth above the transfer table and the pallet.

[0022] As a further improvement to the above technical solution, the stacking assembly includes a fixed frame and a chain conveyor. The fixed frame is located on the discharge side, and the chain conveyor is disposed inside the fixed frame. The chain conveyor has a rotatable conveying chain. Multiple material support components are connected to the conveying chain at a position below the discharge side. The conveying chain can drive the multiple material support components to move to face the pallet and be arranged in a horizontal direction, or drive the multiple material support components to be staggered from the pallet and arranged in a vertical direction.

[0023] As a further improvement to the above technical solution, a blocking lifting drive is provided below the transfer platform, and a baffle is connected to the blocking lifting drive. An avoidance hole is provided on the transfer platform directly opposite the baffle. The blocking lifting drive can drive the baffle to protrude upward or retract downward into the avoidance hole.

[0024] As a further improvement to the above technical solution, the transfer station is provided with an alignment component, which includes an alignment drive and a backing plate. The alignment drive is disposed on the transfer station, and two backing plates are spaced apart along the horizontal direction perpendicular to the direction of movement of the feeding end. The alignment drive can drive the two backing plates to move closer to or further away from each other.

[0025] As a further improvement to the above technical solution, the present invention also includes a second pushing assembly, the second pushing assembly having a second pushing plate that can move back and forth between the feeding end and the transfer table.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The material stacking and baling machine includes a stacking mechanism, a conveying mechanism 500, a discharge assembly, a vertical sealing assembly 600, a film feeding assembly, and a side sealing assembly 700, wherein:

[0042] The stacking mechanism has pallets 310 for stacking materials;

[0043] The conveying mechanism 500 includes a conveying component and a pressing component. The conveying component is located on one side of the pallet 310, and the pressing component can move downward toward or upward away from the conveying component.

[0044] The discharge assembly has a discharge plate 420 that can move back and forth between the pallet 310 and the conveying assembly;

[0045] The vertical sealing assembly 600 is located between the pallet 310 and the conveying assembly. The vertical sealing assembly 600 includes an upper vertical sealing head 610 and a lower vertical sealing head 620, which are movable vertically. A cutter 630 is disposed within the upper vertical sealing head 610. Naturally, a groove for accommodating the cutter 630 is provided on the bottom side of the upper vertical sealing head 610, and the cutter 630 is positioned within this groove. A blade holder is also provided on the lower vertical sealing head 620 corresponding to the position of the cutter 630. The cutter 630 presses the packaging film against the blade holder, thus cutting the packaging film. Naturally, as... Figure 4 As shown, two first vertical sealing lifting drives and two second vertical sealing lifting drives are provided in the vertical sealing assembly 600. The two first vertical sealing lifting drives and the two second vertical sealing lifting drives can be driven by electric screws, cylinders or hydraulic cylinders, etc. The two upper vertical sealing heads 610 are respectively set on the two first vertical sealing lifting drives, and the two first vertical sealing lifting drives drive the two upper vertical sealing heads 610 to move up and down. The two lower vertical sealing heads 620 are respectively set on the two second vertical sealing lifting drives, and the two second vertical sealing lifting drives drive the two lower vertical sealing heads 620 to move up and down.

[0046] The film feeding assembly can feed film between the pallet 310 and the conveying assembly. The film feeding assembly includes two unwinding rollers and multiple guide rollers, each driven by two motors. The two unwinding rollers are respectively loaded with packaging film rolls, which can release the packaging film separately. The packaging film is guided by the multiple guide rollers and fed to the pallet 310 and the conveying assembly for splicing to form a continuous packaging film. The two packaging films can be fed to the pallet 310 and the conveying assembly in the vertical direction, or they can be fed to the pallet 310 and the conveying assembly from the left and right sides.

[0047] The side sealing assembly 700 includes an upper side sealing head 710 and a lower side sealing head 720 located on both sides of the conveying assembly. The two upper side sealing heads 710 and the two lower side sealing heads 720 can move up and down respectively.

[0048] As described above, after the materials are stacked on the pallet 310, the film feeding assembly can feed the packaging film between the pallet 310 and the conveying assembly, so that the packaging film will be spread out between the pallet 310 and the conveying assembly. The discharge plate 420 in the discharge assembly moves from the pallet 310 to the conveying assembly, pushing the materials on the pallet 310 to the conveying assembly. During this process, one side of the stacked materials abuts against the packaging film, so that the packaging film wraps around the upper and lower sides of the stacked materials. Then, the pressing assembly moves closer to the conveying assembly, pressing the stacked materials and the packaging film together in the vertical direction, so that the packaging film fits the stacked materials more tightly. Then, the upper vertical sealing head 610 in the vertical sealing assembly 600 moves downward and the lower vertical sealing head 620 moves upward, using the upper vertical sealing head 610 and the lower vertical sealing head 620 to... The other side of the packaging film is heat-sealed from top to bottom. The cutter 630 inside the upper vertical sealing head 610 is used to cut the middle position of the heat-sealed packaging film, cutting out the packaging film wrapped around the outside of the stacked material, and reserving a continuous packaging film for the next packaging of the stacked material. After the vertical sealing component 600 completes the sealing of one side of the packaging film, the side sealing component 700 seals both sides of the stacked material. The two upper side sealing heads 710 move downward and the two lower side sealing heads 720 move upward, pressing and heat-sealing the parts of the packaging film on both sides of the stacked material, thus completing the packaging of the material around its perimeter. In this way, the material after stacking can be directly wrapped and sealed, saving the steps of material transfer and greatly improving the efficiency of material stacking and packaging.

[0049] In the conveying mechanism 500, the conveying assembly and the pressing assembly can be continuous, integrated structures. However, to facilitate the coordination of vertical sealing and side sealing actions, the conveying assembly and the pressing assembly can be designed as separate structures. Specifically, the conveying assembly includes a first conveyor 510 and a second conveyor 520 arranged sequentially along the direction away from the pallet 310. The pressing assembly includes a third conveyor 530 located above the first conveyor 510 and a fourth conveyor 540 located above the second conveyor 520. The third conveyor 530 can move downward toward or upward away from the first conveyor 510, and the fourth conveyor 540 can move downward toward or upward away from the second conveyor 520. The two upper sealing heads 710 and the two lower sealing heads 720 are respectively... Located on both sides of the second conveyor 520, in practical applications, the first conveyor 510, the second conveyor 520, the third conveyor 530, and the fourth conveyor 540 can each be a belt conveyor. Naturally, in order for the third conveyor 530 and the fourth conveyor 540 to move in the vertical direction, the conveying assembly is equipped with a first downward lifting drive and a second downward lifting drive. The first downward lifting drive and the second downward lifting drive can each be driven by a power source such as an electric screw, a pneumatic cylinder, or a hydraulic cylinder. The third conveyor 530 is mounted on the first downward lifting drive, and the third conveyor 530 moves up and down driven by the first downward lifting drive. The fourth conveyor 540 is mounted on the second downward lifting drive, and the fourth conveyor 540 moves up and down driven by the second downward lifting drive.

[0050] In this conveyor mechanism 500, the discharge plate 420 pushes the stacked material from the pallet 310 onto the first conveyor 510, where the first conveyor 510 supports the material. At this time, the packaging film wraps around one side and the top and bottom of the stacked material. The third conveyor 530 and the fourth conveyor 540 move down. First, the third conveyor 530 presses the stacked material tightly onto the first conveyor 510. Then, the upper vertical sealing head 610 and the lower vertical sealing head 620 clamp the packaging film onto the other side of the stacked material. After one side is heat-sealed and cut, the first conveyor 510 and the third conveyor 530 keep the stacked material pressed and send the stacked material between the second conveyor 520 and the fourth conveyor 540. The second conveyor 520 and the fourth conveyor 540 continue to keep the stacked material pressed and transferred. Then the two upper sealing heads 710 and the two lower sealing heads 720 approach each other to clamp and heat-seal both sides of the packaging film, thus completing the heat sealing of the packaging film on both sides of the stacked material.

[0051] To ensure a better fit between the upper sealing head 710 and the lower sealing head 720 when heat-sealing the packaging film, in this embodiment, the conveying width of the second conveyor 520 is smaller than that of the first conveyor 510. When the two lower sealing heads 720 are at the bottom of their travel, they are positioned close to both sides of the second conveyor 520 and directly opposite the first conveyor 510. Since the conveying width of the second conveyor 520 is smaller than that of the first conveyor 510, when the stacked material moves to the first conveyor 510, there are portions on both sides of the stacked material that protrude from the second conveyor 520. At this time, the two lower sealing heads 720, close to the sides of the stacked material, can support the packaging film protruding from the sides of the stacked material. After the fourth conveyor 540 presses down and positions the stacked material, the upper sealing head 710 and the lower sealing head 720 clamp the packaging film from the upper and lower sides respectively, and the packaging film can fit closer to the sides of the stacked material, thereby effectively improving the tightness of the packaging film in sealing the stacked material.

[0052] To better accommodate stacked materials of different sizes, the positions on both sides of the second conveyor 520 can be widened. Specifically, the conveying assembly also includes two fifth conveyors 550. One end of each of the two fifth conveyors 550 is rotatably connected to the ends of the first conveyor 510 near the second conveyor 520. The two fifth conveyors 550 can rotate upwards to be flush with the first conveyor 510 or downwards away from the first conveyor 510. The two upper end caps 710 and the two lower end caps 720 can move in the direction of approaching or moving away from the second conveyor 520, respectively. The upper end caps 710 and the lower end caps 720 located on the same side are installed on the same frame. By sliding and adjusting the frame and locking it, the two upper end caps 710 and the two lower end caps 720 can move in the direction of approaching or moving away from the second conveyor 520. In practical applications, in order to enable the two fifth conveyors 550 to rotate up and down, a drive source such as a motor or rotary cylinder can be provided to drive the fifth conveyor 550 to rotate up and down. Alternatively, a drive source such as a cylinder, electric screw, or hydraulic cylinder can be hinged to the bottom side of the two fifth conveyors 550, so that the fifth conveyor 550 can rotate up or down by lifting or lowering it.

[0053] In this embodiment, when the size of the stacked material to be transported is small, it can be transported by the second conveyor 520 alone. When the size of the stacked material to be transported is large, the two fifth conveyors 550 can be rotated upwards to be flush with the first conveyor 510. At this time, the first conveyor 510 and the fifth conveyors 550 on both sides jointly support and transport the stacked material. The two upper end caps 710 and the two lower end caps 720 can be adjusted in position away from the second conveyor 520 to adapt to the packaging position on both sides of the stacked material, thus further improving the overall flexibility of use.

[0054] To ensure that the upper sealing head 710 can press the portion of the packaging film protruding from the stacked material downwards onto the lower sealing head 720, the portion of the packaging film protruding from the stacked material needs to be straightened first. Specifically, as follows: Figure 3 As shown, the side sealing assembly 700 also includes connecting frames 730 located beside the two upper sealing heads 710. Multiple vacuum suction cups 731 are connected to each of the two connecting frames 730. The two connecting frames 730 can be tilted downwards towards or upwards away from the conveying assembly. When the stacked material is conveyed to the second conveyor 520, the two connecting frames 730 tilt downwards towards both sides of the stacked material, causing the multiple vacuum suction cups 731 to abut against the portion of the packaging film protruding from the stacked material and press against it, ensuring that the multiple vacuum suction cups 731 can adsorb the packaging film. Then, the two connecting frames tilt upwards away from the stacked material, supporting the portion of the packaging film protruding from the stacked material. This allows the upper sealing head 710 to move downwards and press the packaging film downwards, thus improving the stability of the packaging film during heat sealing on both sides of the stacked material.

[0055] To enable the tilting movement of the two connecting frames 730, motors are respectively installed on the sides of the two upper end caps 710. These motors are connected to gears, and each of the two connecting frames 730 is connected to an arc-shaped rack, which meshes with the two gears. During operation, the power transmission from the motors to the gears and the two arc-shaped racks causes the two connecting frames 730 to tilt downwards towards the stacked material, or tilt upwards away from the stacked material.

[0056] The discharge assembly has a drive source that can drive the discharge plate 420 to reciprocate in a straight line. It has various structural forms. For example, the discharge assembly is equipped with a drive source such as an electric screw, a cylinder or a hydraulic cylinder to drive the discharge plate 420 to move back and forth. In this embodiment, the discharge assembly includes a mounting frame 440, a first belt conveyor and a push arm. The first belt conveyor is connected to the mounting frame 440 and has a first conveyor belt that can rotate. The push arm is slidably connected to the mounting frame 440. A first synchronization block is connected between the push arm and the first conveyor belt. The discharge plate 420 is connected to the push arm. The first belt conveyor includes multiple pulleys mounted on the mounting frame 440. The multiple pulleys tension the first transmission belt and are synchronously connected to the first transmission belt. When the first transmission belt rotates, it can drive the push arm to slide, thereby driving the discharge plate 420 to move back and forth in a straight line. This allows the discharge plate 420 to have a longer stroke and reduces the space occupied by the drive structure of the discharge plate 420.

[0057] The stacking assembly is mainly used for stacking and arranging materials. Specifically, the stacking mechanism includes:

[0058] The transfer station 100 is located on the side of the pallet 310 away from the conveying assembly. The side of the transfer station 100 away from the pallet 310 is the feeding side and the other side is the discharging side. The pallet 310 can be retracted downward or protruded upward from the discharging side.

[0059] The feeding assembly 200 is located on the feed side. The feeding assembly 200 has a feeding end that moves toward the transfer table 100. In practical applications, the feeding assembly 200 can be a belt conveyor with a rotating conveyor belt inside. In this case, the conveyor belt is the feeding end.

[0060] The stacking assembly has a material support member 320 that can be moved above the pallet 310 or moved to a position offset from the pallet 310;

[0061] The first pusher assembly has a first pusher plate 410 that can move back and forth above the transfer table 100 and the pallet 310.

[0062] As described above, the feeding assembly 200 can be connected to an external workstation to deliver the material to be stacked to the feeding end. The feeding end then transfers the material to the transfer table 100. The pallet 310 then moves upwards to the discharge side, at which point the material support 320 is in a state of moving away from the discharge side. The first pusher 410 within the first pusher assembly pushes the material from the transfer table 100 onto the pallet 310. The first pusher assembly then returns to its reset position, and the feeding end continues to transfer the material to the transfer table 100, while the pallet 310 moves the material downwards. At this point, the material support 320 is in a state of moving towards... In the state near the discharge side, the first pusher plate 410 in the first pusher assembly pushes the material from the transfer table 100 to the material support 320, ensuring that the material is arranged in place above the material support 310. The material support 320 then moves away from the discharge side and is pulled out from under the material, causing the material on the material support 320 to fall and stack on the material on the material support 310, thus achieving material stacking. This process is repeated to stack one or more materials on the material support 310 in the vertical direction. After stacking is completed, the whole thing is pushed out from the discharge plate 420 to the conveying assembly, thus completing the stacking arrangement of materials one by one.

[0063] The material support 320 can be a plate, driven by a linear drive source such as an electric screw, cylinder, or hydraulic cylinder to move it closer to or away from the discharge side, thereby supporting the material and pulling it out from the bottom of the arranged material. To facilitate pulling the material support 320 out from under the material and reduce friction with the material, the material support 320 can be a rod, column, etc. In this case, multiple material support 320s are needed. To move multiple material support 320s, in this embodiment, such as... Figure 6 As shown, the stacking assembly includes a fixed frame 331 and a chain conveyor 332. The fixed frame 331 is located on the discharge side, and the chain conveyor 332 is disposed inside the fixed frame 331. The chain conveyor 332 has a rotatable conveying chain 333. The conveying chain 333 is connected to a plurality of material support components 320 at a position below the discharge side. The conveying chain 333 can drive the plurality of material support components 320 to move to face the pallet 310 and be arranged in a horizontal direction, or drive the plurality of material support components 320 to be staggered from the pallet 310 and arranged in a vertical direction.

[0064] In this embodiment, the chain conveyor 332 has structural components such as a motor and sprockets mounted on a fixed frame 331. Multiple sprockets mounted on the fixed frame 331 tension and support the conveyor chain 333, and the motor drives one of the sprockets to rotate, thereby realizing the rotational movement of the conveyor chain 333. At this time, multiple rod-shaped or columnar material support members 320 are respectively connected to multiple links of the conveyor chain 333. When the conveyor chain 333 rotates, it can drive the multiple material support members 320 to switch between horizontal and vertical positions. Specifically, when material needs to be transferred to the pallet 310, the conveyor chain 333 rotates, driving the multiple material support members 320 to move into a vertically aligned state. At this time, the multiple material support members 320 are staggered from the pallet 310, and the pallet 310 can move vertically without interfering with the material support members 320. Due to motion interference, it is natural that some of the material support components 320 can remain in a horizontally arranged state, located between the pallet 310 and the transfer table 100, so that the pallet 310 and the transfer table 100 can connect. When it is necessary to transfer materials to multiple material support components 320, the conveyor chain 333 rotates, driving multiple material support components 320 to move above the pallet 310 and the materials loaded on the pallet 310. At this time, multiple material support components 320 are arranged in a horizontal direction, forming a connected and continuous material support structure on the discharge side. At this time, multiple material support components 320 are in a state directly facing the pallet 310, which facilitates the arrangement of materials above the pallet 310. After completion, the conveyor chain 333 drives multiple material support components 320 to move closer to the discharge side and pull them out from the bottom side of the material, realizing the stacking of materials, which is especially suitable for stacking multiple side-by-side materials.

[0065] The stacking assembly includes a drive source that can move the pallet 310 up and down. Specifically, the stacking assembly includes a fixed plate 311 and a stacking lifting drive 312 mounted on the fixed plate 311. The stacking lifting drive 312 is connected to the pallet 310 and can move the pallet 310 up and down. In practical applications, the stacking lifting drive 312 can be an electric screw, a pneumatic cylinder, or a hydraulic cylinder. When material is pushed onto the pallet 310, the position of the material away from the discharge side can abut against the fixed plate 311, which limits and aligns it, thus facilitating the arrangement and organization of the material on the fixed plate 311. The pallet 310 is powered by the stacking lifting drive 312 to move up and down, allowing the pallet 310 to move upward to the discharge side to receive material, and to move downward when stacking material.

[0066] To better limit the material entering pallet 310, such as Figure 7As shown, in this embodiment, limiting plates 313 are respectively connected to the fixed plate 311 at positions on both sides of the pallet 310. When material enters the pallet 310, the two limiting plates 313 can limit the material on both sides, thereby improving the effect of arranging and organizing the material. In practical applications, since it is necessary to avoid the material support 320, the position of the limiting plate 313 corresponding to the material support 320 can be provided with avoidance holes, or two limiting plates 313 can be provided at intervals along the vertical direction to avoid the movement of the material support 320.

[0067] When material enters the transfer station 100, its movement on the transfer station 100 can be limited, thereby aligning the material's position on the transfer station 100. Specifically, a blocking and lifting drive is provided below the transfer station 100, and the blocking and lifting drive is connected to a baffle 110. The transfer station 100 has a clearance hole directly opposite the baffle 110. The blocking and lifting drive can cause the baffle 110 to protrude upward or retract downward into the clearance hole. In practical applications, the blocking and lifting drive can be a cylinder, an electric lead screw, or a hydraulic cylinder, etc. When material is fed into the transfer station 100 at the feeding end, the blocking and lifting drive causes the baffle 110 to move upward and protrude out of the clearance hole, thereby blocking and limiting the material. At this time, the material can be aligned and arranged in the direction from the feeding side to the discharging side. Then, the blocking and lifting drive causes the baffle 110 to retract downward into the clearance hole, allowing the material to enter the pallet 310 from the transfer station 100.

[0068] Furthermore, the transfer station 100 is equipped with an alignment assembly, which includes an alignment drive 121 and a backing plate 122. The alignment drive 121 is mounted on the transfer station 100, and two backing plates 122 are spaced apart along a horizontal direction perpendicular to the feeding end. The alignment drive 121 can move the two backing plates 122 closer together or further apart. In practical applications, the alignment drive 121 can be a bidirectional electric screw with two movable ends that can move closer together or further apart, connecting the two backing plates 122 to the two movable ends respectively; or a belt conveyor can be used to transport the two backing plates 122 to both sides of the belt respectively. In use, when the material moves from the feeding end into the transfer station 100, the alignment drive 121 moves the two backing plates 122 closer together, thus aligning and organizing the other two sides of the material, thereby further improving the effect of stacking multiple materials. After completion, the alignment drive 121 moves the two backing plates 122 further apart.

[0069] The first feeding assembly has a drive source that can move the first pusher plate 410, specifically, such as Figure 8As shown, the first pushing assembly includes a first translation drive 411, a first rotation drive 412, and a first swing arm 413. The first rotation drive 412 is disposed on the first translation drive 411. The first translation drive 411 can drive the first rotation drive 412 to reciprocate along a straight line. The first rotation drive 412 is connected to the first swing arm 413. The first rotation drive 412 can drive the first swing arm 413 to rotate along a horizontal axis. The first push plate 410 is connected to the bottom end of the first swing arm 413. The first translation drive 411 provides the driving force for the reciprocating translational movement of the first push plate 410. Its structure can take various forms, such as a cylinder, electric lead screw, or hydraulic cylinder. To drive the first push plate 410 to move a longer stroke, the first translation drive 411 can employ a second belt conveyor. The second belt conveyor is connected to the mounting frame 440 and has a rotatable second conveyor belt. A second synchronization block is slidably connected to the mounting frame 440, and the first rotary drive 412 is positioned on the second synchronization block. The second belt conveyor includes multiple pulleys mounted on the mounting frame 440. These pulleys tension the second conveyor belt and are synchronously connected to it. When the second conveyor belt rotates, it can drive the first swing arm 413 to slide, thereby causing the first push plate 410 to move back and forth in a straight line.

[0070] In the first feeding assembly, when the material needs to be transferred to the pallet 310, the first rotary drive 412 can drive the first swing arm 413 to rotate downward, and then the first translation drive 411 drives the first swing arm 413 to move towards the transfer table 100 to deliver the material to the pallet 310. Then the first rotary drive 412 rotates upward to reset, and the first translation drive 411 drives the first swing arm 413 to return to the reset position to prepare for the next material transfer.

[0071] To ensure the material is properly transferred to the transfer station 100, the present invention further includes a second pushing assembly. The second pushing assembly has a second push plate 430 that can move back and forth between the feeding end and the transfer station 100. The second pushing assembly includes a drive source that can move the second push plate 430. Specifically, the second pushing assembly includes a second translation drive, a second rotation drive, and a second swing arm. The second rotation drive is mounted on the second translation drive and can drive the second rotation drive to reciprocate along a linear direction. The second rotation drive is connected to the second swing arm, and can drive the second swing arm to rotate along a horizontal axis. The second push plate 430 is connected to the bottom end of the second swing arm. The second translational drive provides the driving force for the reciprocating translational movement of the second push plate 430. Its structure can take various forms, such as a cylinder, electric lead screw, or hydraulic cylinder. To drive the second push plate 430 to move a longer stroke, the second translational drive can employ a third belt conveyor. The third belt conveyor is connected to the mounting frame 440 and has a rotatable third conveyor belt. A third synchronizing block is slidably connected to the mounting frame 440, and the second rotary drive is positioned on the third synchronizing block. The second belt conveyor includes multiple pulleys mounted on the mounting frame 440. These pulleys tension the third conveyor belt and are synchronously connected to it. When the third conveyor belt rotates, it drives the third swing arm to slide, thereby causing the third push plate to move back and forth in a linear direction.

[0072] When materials need to be transferred to the transfer station 100, the second rotary drive can drive the second swing arm to rotate downwards, and then the second translation drive can drive the second swing arm to move towards the transfer station 100 to deliver the materials to the transfer station 100. Then the second rotary drive rotates upwards to reset, and the second translation drive drives the second swing arm to return to the reset position to prepare for the next material transfer.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
