Description

Technical Field

[0001] This utility model relates to the field of automated feeding technology, specifically a dual-track feeding mechanism for rotatable materials. Background Technology

[0002] With the continuous deepening of industry and the rapid development of intelligent technology, the rapid advancement of modern science and technology has provided more possibilities for reducing production costs and improving efficiency. With the development of automation technology, automated production equipment is gradually becoming popular in various industries, and most automated equipment involves automated product tray loading and unloading.

[0003] Currently, automated pallet loading typically involves stacking multiple pallets one on top of the other, then manually removing each pallet from the stack and placing it at the loading station. From there, the pallets are transported to the next station via a conveyor or other handling mechanism, facilitating product placement within the pallets. However, this manual palletizing method is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-track feeding mechanism for rotatable materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-track feeding mechanism for rotatable materials, comprising a first dual-track belt line and a second dual-track belt line that are connected to each other, a third dual-track belt line with the same conveying direction is provided on the inner side of the first dual-track belt line, a lifting and rotating structure is provided on the end of the third dual-track belt line near the second dual-track belt line, a pushing structure with the same conveying direction is provided on the inner side of the second dual-track belt line, and a pallet limiting structure and a pallet assembly are mounted on the end of the second dual-track belt line away from the first dual-track belt line; The lifting and rotating structure includes a lifting assembly installed between the third double-track belt lines. A rotating assembly is provided above the lifting assembly, and a rotating platform is connected above the rotating assembly. The rotating platform is a cross-shaped structure with two long sides and two short sides, and all four sides are provided with retaining edges. The pushing structure includes a support frame, on which a horizontal driving structure is provided. The horizontal driving structure is connected to two interconnected push rod assemblies. Two limiting plates are provided at the end of the support frame near the third double track belt line, and bearings are provided at the ends of the two limiting plates away from the third double track belt line.

[0006] In a further optimization, the lifting assembly includes a horizontally positioned fixed plate. A vertically positioned first cylinder is mounted below the fixed plate. A lifting plate is connected to the piston rod end of the first cylinder. Several guide members connect the lifting plate and the fixed plate. The first cylinder drives the lifting plate to rise and fall, thereby causing the rotating assembly and the turntable to rise and fall, achieving the lifting of the pallet.

[0007] In a further optimization, the rotating assembly includes a first motor vertically mounted below the lifting plate. The upper output shaft of the first motor is connected to a first drive wheel. A first driven wheel is rotatably connected to the lifting plate. A first belt connects the first drive wheel and the first driven wheel. A rotating shaft is connected upwards from the center of the first driven wheel, and the rotating shaft is connected to the center of the rotary table. The first motor drives the first drive wheel to rotate, which in turn drives the first driven wheel to rotate via the first belt, ultimately rotating the rotating shaft and thus the rotary table.

[0008] Further optimization involves a pallet limiting structure comprising two vertically arranged guide plates and two baffles. The guide plates and baffles are symmetrically positioned on the two tracks of the second double-track conveyor belt. Each guide plate is connected to a horizontally arranged second cylinder. The baffles are located on the sides of the guide plates away from the first double-track conveyor belt, and a blocking component is provided on the sides of the baffles away from the guide plates. The guide plates and baffles limit the forward, backward, left, and right movements of the entire stack of pallets, ensuring the stability of the stack.

[0009] Further optimization involves two blocking components, each positioned on the side of one of the two baffles. Each blocking component includes a vertically positioned third cylinder, with its upper piston rod connected to a blocking sheet metal. The third cylinder drives the blocking sheet metal to rise and fall, thereby blocking the tray on the second double-track belt conveyor.

[0010] In a further optimization, there are two pallet assemblies symmetrically arranged on the two tracks of the second double-track belt conveyor, and each pallet assembly is disposed between the corresponding guide plate and baffle on the second double-track belt conveyor. The pallet assembly includes a horizontally mounted mounting base plate, on which a horizontally mounted fourth cylinder is mounted. The piston rod end of the fourth cylinder is connected to a horizontally mounted pallet, and a second linear guide rail connects the pallet and the mounting base plate.

[0011] In a further optimization, the horizontal drive structure includes a second motor vertically mounted at one end of the support frame. The upper output shaft of the second motor is connected to a second drive wheel, and the other end of the support frame has a second driven wheel. A second belt connects the second drive wheel and the second driven wheel. The second motor drives the second drive wheel to rotate, thereby driving the second belt to transmit power between the second drive wheel and the second driven wheel, achieving synchronous left and right movement of the push rod assembly.

[0012] Further optimization involves the two push rod assemblies being located on opposite sides of the second belt, and the support frame being equipped with two first linear guide rails that are respectively connected to the two push rod assemblies. A protective cover is provided above the support frame. The push rod assembly includes a connecting block connected to a slider of a first linear guide rail. The connecting block is connected to a vertical plate, and a push rod is rotatably connected to the vertical plate. The middle of the push rod is rotatably connected to the vertical plate. A first spring is connected to the end of the push rod near the connecting block. The lower end of the first spring is connected to the vertical plate and the first spring is in a stretched state.

[0013] In a further optimization, two horizontally arranged connecting shafts are connected between the connecting block and the upright plate. The connecting shafts are movably connected to the connecting block, and a second spring is sleeved on the connecting shaft. The two ends of the second spring abut against the connecting block and the upright plate, respectively.

[0014] Further optimization includes two fifth cylinders on the inner side of the first double-track belt conveyor near the end of the second double-track belt conveyor, a sixth cylinder on the inner side of the third double-track belt conveyor away from the end of the second double-track belt conveyor, a clearance part for the rotary table to avoid on the two tracks of the third double-track belt conveyor, and a stop block on each of the two tracks of the third double-track belt conveyor near the end of the second double-track belt conveyor.

[0015] Beneficial effects: This utility model's dual-track feeding mechanism for rotatable materials, through the coordinated arrangement of a first, second, and third dual-track belt conveyor, achieves the conveying and turning of a stack of pallets, facilitating pallet feeding. Whether feeding along the length or width, pallet feeding is achieved. A lifting and rotating structure enables the rotation and reversal of the entire stack of pallets, allowing them to rotate 90°. A pallet limiting structure limits the entire stack of pallets, ensuring the stability of the stack and the stability of the second-to-last pallet and the pallets stacked above it during individual feeding. A pallet assembly lifts all pallets except the bottom one, facilitating individual pallet separation. A pushing structure pushes the bottommost separated pallet from the stack, pushing it to the right and enabling individual pallet feeding. The dual-track feeding mechanism has a clever and compact structural design, enabling the conveying of entire stacks of pallets as well as the feeding of individual pallets. It facilitates pallet rotation and reversal, and can convey entire stacks of pallets at once, while also enabling continuous feeding of individual pallets. This dual-track feeding mechanism ensures continuous pallet feeding operations, guarantees operational continuity, and improves production efficiency. Attached Figure Description

Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, a dual-track feeding mechanism for rotatable materials includes a first dual-track belt line 1 and a second dual-track belt line 2 that are connected to each other. A third dual-track belt line 3 with the same conveying direction is provided on the inner side of the first dual-track belt line 1. A lifting and rotating structure 4 is provided on the end of the third dual-track belt line 3 near the end of the second dual-track belt line 2. A pushing structure 6 with the same conveying direction is provided on the inner side of the second dual-track belt line 2. A pallet limiting structure 5 and a pallet assembly 7 are mounted on the end of the second dual-track belt line 2 away from the first dual-track belt line 1. The lifting and rotating structure 4 includes a lifting component 41 installed between the third double track belt lines 3. A rotating component 42 is provided above the lifting component 41. A rotating platform 43 is connected above the rotating component 42. The rotating platform 43 is a cross-shaped structure with two long sides and two short sides, and all four sides are provided with retaining edges 44. The pushing structure 6 includes a support frame 61, on which a horizontal drive structure 62 is provided. The horizontal drive structure 62 is connected to two interconnected push rod assemblies 63. Two limiting plates 64 are provided at the end of the support frame 61 near the third double track belt 3, and bearings 65 are provided at the ends of the two limiting plates 64 away from the third double track belt 3.

[0021] In this application, the dual-track feeding mechanism is used for automatic feeding of pallets stacked vertically. It can automatically rotate the stack of pallets by 90°, reversing their direction before conveying them, and then individually feed each pallet, achieving automated feeding of multiple pallets at once. Direct connection between the first dual-track belt conveyor 1 and the second dual-track belt conveyor 2 enables direct conveying of the stack of pallets without reversing their direction. Alternatively, the stack of pallets can be conveyed via the third dual-track belt conveyor 3, then rotated 90° by the lifting and rotating structure 4 before being conveyed to the second dual-track belt conveyor 2, facilitating subsequent individual pallet feeding. The pallet limiting structure 5 limits the stack of pallets, ensuring stable placement and facilitating individual pallet feeding. The pushing structure 6 pushes the pallets one by one, achieving individual pallet feeding. The pallet assembly 7 is used to lift the pallet, which facilitates the pushing structure 6 to push the bottom pallet out, thus enabling the pallet to be loaded one by one in sequence.

[0022] In this application, the lifting and rotating structure 4 includes a lifting component 41, a rotating component 42, and a rotating platform 43. The lifting component 41 lifts the rotating component 42 and the rotating platform 43 upwards, lifting a stack of pallets located above the rotating platform 43 and separating them from the belt of the third double-track conveyor belt 3. The rotating component 42 drives the rotating platform 43 to rotate 90°, thereby rotating the pallets located on the rotating platform 43 by 90°, turning pallets from left-right to front-back arrangement, changing them to the desired orientation, and matching with the pallet limiting structure 5 for subsequent individual pallet loading. The rotating platform 43 has a cross-shaped structure composed of two long sides and two short sides, matching the long and wide sides of the pallet to ensure the stability of the lifted pallet. The retaining edge 44 on the rotating platform 43 matches the pallet, limiting its position and ensuring smooth lifting.

[0023] In this application, the pushing structure 6 includes a support frame 61, a horizontal drive structure 62, a push rod assembly 63, and a limiting plate 64. The support frame 61 is arranged on the left and right sides, and the limiting plate 64 is located at the left end of the support frame 61. The push rod assembly 63 is connected to the horizontal drive structure 62 through a toothed plate. The horizontal drive structure 62 can drive the push rod assembly 63 to move left and right. When the push rod assembly 63 is on the left side, it can move downward under the action of the limiting plate 64, which facilitates the movement of the stack of pallets on the second double-track belt conveyor 2 from left to right. When the push rod assembly 63 can move to the right under the action of the horizontal drive structure 62, it is no longer restricted by the limiting plate 64 and can return to its initial state. When it moves to the right, it can push out the bottom pallet of the stack under the action of the horizontal drive structure 62 and move it to the next station, realizing automatic pallet feeding. The right end of the limiting plate 64 is provided with a bearing 65, which is used to contact the push rod assembly 63 to achieve rolling contact with the push rod assembly 63. The contact area is small, the friction is small, and the movement of the push rod assembly 63 is smooth. In this application, there are two push rod assemblies 63 and two limiting plates 64, which are respectively arranged on the front and rear sides of the support frame 61. The two push rod assemblies 63 can push the pallet at two points, ensuring that the pallet is pushed accurately, smoothly and stably. The two limiting plates 64 and the bearing 65 at their right ends are used to limit the two push rod assemblies 63 respectively.

[0024] like Figure 4 As shown, in one embodiment of this application, the lifting assembly 41 includes a horizontally arranged fixed plate 411, a vertically arranged first cylinder 412 is installed below the fixed plate 411, a lifting plate 413 is connected to the piston rod end above the first cylinder 412, and a plurality of guide members 414 are connected between the lifting plate 413 and the fixed plate 411.

[0025] In this embodiment, the lifting assembly 41 includes a fixing plate 411, a first cylinder 412, and a lifting plate 413. The fixing plate 411 is used to mount the first cylinder 412. The extension and retraction of the piston rod of the first cylinder 412 drives the lifting plate 413 connected to it to move up and down synchronously, thereby driving the rotating assembly 42 mounted on the lifting plate 413 to move up and down synchronously, which in turn drives the rotating table 43 to move up and down. This facilitates the separation of the stack of pallets conveyed to the top of the rotating table 43 from the belt of the third double-track conveyor belt 3, making it easier to rotate and change the direction of the stack of pallets. The guide member 414 is used to guide the lifting plate 413 to move up and down, ensuring that the lifting plate 413 moves up and down smoothly and steadily. In this embodiment, there are four guide members 414 arranged in a rectangular array, and the four guide members 414 are distributed around the first cylinder 412, further improving the stability of the lifting plate 413.

[0026] like Figure 4As shown, the rotating assembly 42 further includes a first motor 421 vertically mounted below the lifting plate 413. A first drive wheel 422 is connected to the upper output shaft of the first motor 421. A first driven wheel 423 is rotatably connected to the lifting plate 413. A first belt 424 connects the first drive wheel 422 and the first driven wheel 423. A rotating shaft 425 is connected upwards to the center of the first driven wheel 423, and the rotating shaft 425 is connected to the center of the rotating platform 43. The first motor 421 drives the first drive wheel 422 to rotate, and the first belt 424 drives the first driven wheel 423 to rotate synchronously. The first driven wheel 423 drives the rotating shaft 425 to rotate, and the rotation of the rotating shaft 425 drives the rotating platform 43 to rotate synchronously, thereby rotating the pallet 90° and changing the pallet's orientation from left-right to front-back, facilitating pallet transport by the second double-track belt conveyor 2.

[0027] like Figure 1 and Figure 5 As shown, in another embodiment of this application, the pallet limiting structure 5 includes two vertically arranged guide plates 51 and two baffles 53. The two guide plates 51 and two baffles 53 are symmetrically arranged on the two tracks of the second double track belt 2. The two guide plates 51 are respectively connected to a horizontally arranged second cylinder 52. The baffles 53 are arranged on the side of the guide plates 51 away from the first double track belt 1. The side of the baffles 53 away from the guide plates 51 is provided with a blocking component 54.

[0028] In this embodiment, the pallet limiting structure 5 includes guide plates 51, a second cylinder 52, baffles 53, and blocking components 54. Two guide plates 51 and two baffles 53 are symmetrically arranged to form a rectangular array, enabling precise positioning of rectangular pallets and ensuring the stability of the stack. This also ensures that when a single pallet is being pushed out for loading, the pallets above it remain stable and do not collapse. The two guide plates 51 can move synchronously in opposite directions via the connected second cylinder 52. This allows the stack of pallets to be conveyed to the position of the baffle 53 when transported by the second double-track conveyor belt 2. After being blocked by the baffle 53, the second cylinder 52 drives the guide plates 51 to move inwards towards the second double-track conveyor belt 2, forming a barrier on the left side of the stack of pallets. The cooperation of the two baffles 53 achieves a surrounding limit at the four corners of the stack of pallets, ensuring the stability of the entire stack. The blocking component 53 is used to block the bottommost pallet in the stack of pallets to prevent the stack of pallets from becoming unstable due to the movement of the second double-track belt 2.

[0029] Furthermore, there are two blocking components 54, each positioned on the side of one of the two baffles 53. Each blocking component 54 includes a vertically positioned third cylinder 541, with a blocking sheet metal 542 connected to the upper piston rod of the third cylinder 541. The two blocking components 54 are positioned one in front of the other, respectively blocking and limiting the front and rear points on the right side of the tray, ensuring a blocking effect. The third cylinder 541 drives the blocking sheet metal 542 to move up and down. When the blocking sheet metal 542 moves upward, it blocks the tray; when it moves downward, it does not block the tray, allowing the pushing structure 6 to push out the bottommost tray, thus achieving individual loading of the tray.

[0030] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, in another embodiment of this application, there are two pallet assemblies 7 symmetrically arranged on the two tracks of the second double track belt line 2, and each pallet assembly 7 is disposed between the corresponding guide plate 51 and baffle 53 on the second double track belt line 2.

[0031] In this embodiment, the pallet assembly 7 is used to lift the entire stack of pallets except for the bottom one, so that the pushing structure 6 can push the bottom one of the entire stack of pallets out, achieving automatic pallet loading. Two pallet assemblies 7 lift the two ends of the pallet along its length from the front and rear sides respectively, ensuring the stability of the entire stack of pallets. The pallet assembly 7 is positioned between the guide plate 51 and the baffle 53, and the guide plate 51 and the baffle 53 limit the left and right movement of the pallet, further ensuring the stability of the pallet being lifted by the pallet assembly 7.

[0032] Furthermore, the pallet assembly 7 includes a horizontally mounted mounting base plate 71, on which a horizontally mounted fourth cylinder 72 is mounted. The piston rod end of the fourth cylinder 72 is connected to a horizontally mounted pallet 73, and a second linear guide rail 74 is connected between the pallet 73 and the mounting base plate 71. The mounting base plate 71 is used to connect the pallet assembly 7 to the second double-track belt conveyor 2. The fourth cylinder 72 is used to push the pallet 73 to move back and forth, so that the pallet 73 is inserted under the second to last pallet in the stack of pallets, thus lifting all pallets except the bottom one. The fourth cylinder 72 can push the pallet 73 to move left and right along the second linear guide rail 74 relative to the mounting base plate 71. When the pallet 73 is inserted under the second to last pallet from top to bottom, it can lift the pallet up to a height equivalent to the thickness of the pallet 73, which makes it easier for the pushing structure 6 to push out the bottom pallet. The second to last pallet and the pallets above it are lifted to a relatively low height, which can ensure the stability of lifting the pallet and ensure that the lifted pallet is placed back on the second double-track belt conveyor 2 more smoothly.

[0033] like Figure 6 As shown, in another embodiment of this application, the horizontal drive structure 62 includes a second motor 621 vertically disposed at one end of the support frame 61. The upper output shaft of the second motor 621 is connected to a second drive wheel 622. The other end of the support frame 61 is provided with a second driven wheel 623. A second belt 624 is connected between the second drive wheel 622 and the second driven wheel 623.

[0034] In this embodiment, the horizontal drive structure 62 includes a second motor 621, a second drive wheel 622, a second driven wheel 623, and a second belt 624. The second drive wheel 622 and the second driven wheel 623 are arranged left and right. The second motor 621 can drive the second drive wheel 622 to rotate, thereby driving the second belt 624 to transmit left and right transmission between the second drive wheel 622 and the second driven wheel 623, thereby driving the push rod assembly 63 to move left and right. The second belt 624 is connected to two interconnected push rod assemblies 63, thereby driving the two push rod assemblies 63 to move left and right synchronously. The left and right movement of the push rod assembly 63 realizes the pushing and feeding of the pallet.

[0035] Furthermore, the two push rod assemblies 63 are respectively located on both sides of the second belt 624, and the support frame 61 is provided with two first linear guide rails 66 that are respectively connected to the two push rod assemblies 63. A protective cover 67 is provided on the top of the support frame 61.

[0036] In this embodiment, two push rod assemblies 63 are arranged one in front of the other and on both sides of the second belt 624. The two push rod assemblies 63 are connected by a connecting plate and connected to the second belt 624 by a toothed plate. When the second belt 624 drives one push rod assembly 63 to move, it can drive the other push rod assembly 63 to move synchronously through the connecting plate, so as to realize the synchronous left and right movement of the two push rod assemblies 63.

[0037] Furthermore, the push rod assembly 63 includes a connecting block 631 connected to the slider of the first linear guide rail 66. The connecting block 631 is connected to a vertical plate 633. A push rod 634 is rotatably connected to the vertical plate 633. The middle of the push rod 634 is rotatably connected to the vertical plate 633. A first spring 635 is connected to the end of the push rod 634 near the connecting block 631. The lower end of the first spring 635 is connected to the vertical plate 633 and the first spring 635 is in a stretched state.

[0038] The connecting block 631 connects other components of the push rod assembly 63 to the slider of the first linear guide rail 66. The upright plate 633 is used for mounting the push rod 634. The connecting block 631 and the upright plate 633 enable the push rod 634 to move left and right. The middle of the push rod 634 is rotatably connected to the upright plate 633, allowing the push rod 634 to rotate relative to the upright plate 633. A first spring 635 connects the left end of the push rod 634 to the upright plate 633. The first spring 635 pulls the left end of the push rod 634 downward, causing the right end of the push rod 634 to rotate upward, allowing it to tilt upward. The right end of the push rod 634 can match the bottommost pallet in the stack. The left and right movement of the push rod 634 pushes the bottommost pallet in the stack to the right, achieving single pallet loading. In this embodiment, the left and right ends of the push rod 634 are bent in the opposite direction to the middle and are parallel. When push rod 634 moves to the left, it can rotate around the upright plate under the action of the limiting plate 64 and the bearing 65, so that the right end of push rod 634 rotates downward and is lower than the conveying height of the second double track belt 2, which facilitates the second double track belt 2 to convey the pallet to the right. When push rod 634 moves to the right, it is no longer restricted by the limiting plate 64 and the bearing 65, and can rotate relative to the upright plate 633 under the action of the first spring 635. The right end of push rod 634 rotates upward to push the bottommost pallet in the stack.

[0039] Furthermore, two horizontally arranged connecting shafts 632 connect the connecting block 631 and the upright plate 633. The connecting shafts 632 are movably connected to the connecting block 631, and a second spring 636 is sleeved on the connecting shaft 632. The two ends of the second spring 636 abut against the connecting block 631 and the upright plate 633, respectively. The connecting shaft 632 is used to connect the upright plate 633 and the connecting block 631, and the connecting shaft 632 is slidably connected to the connecting block 631 to ensure that the upright plate 633 can move left and right relative to the connecting block 631. At the same time, the second spring 636 on the connecting shaft 632 provides elastic buffering force, which ensures that the push rod 634 connected to the upright plate 633 has elastic buffering capability, avoiding rigid collision of the push rod 634 with the pallet and reducing mechanical impact.

[0040] like Figure 1 , Figure 2 and Figure 8 As shown, in another embodiment of this application, two fifth cylinders 8 are provided on the inner side of the first double track belt 1 near the end of the second double track belt 2, and a sixth cylinder 9 is provided on the inner side of the third double track belt 3 away from the end of the second double track belt 2. The two tracks of the third double track belt 3 are provided with a clearance part 31 for the rotary table 43 to avoid, and a stop block 32 is provided on each of the two tracks of the third double track belt 3 near the end of the second double track belt 2.

[0041] In this embodiment, the fifth cylinder 8 is used for conveying limit on the first double-track belt conveyor 1, which can limit the movement of the pallets conveyed by the first double-track belt conveyor 1 to ensure the orderly conveying of the pallets. The sixth cylinder 9 is used for moving limit on the pallets conveyed by the third double-track belt conveyor 3, which can block the pallets on the left side of the lifting and rotating structure 4, facilitating the lifting and rotating operation of the pallets by the lifting and rotating structure 4. The clearance part 31 on the third double-track belt conveyor 3 is used to avoid the rotating table 43, ensuring that the rotating table 43 will not affect the conveying of the third double-track belt conveyor 3 when the lifting and rotating structure 4 is not lifting. The stop block 32 is used to limit the pallets conveyed by the third double-track belt conveyor 3, ensuring that the entire stack of pallets can stop moving when it is conveyed to the lifting and rotating structure 4, so that the lifting and rotating structure 4 can lift the entire stack of pallets and rotate it 90° before placing it on the first double-track belt conveyor 1.

[0042] like Figure 8 As shown, in this application, the working process of the dual-track feeding mechanism is as follows: 1. The entire stack of pallets is placed on the third double-track conveyor belt 3 with the length direction in a left-right position. After being transported by the third double-track conveyor belt 3 to the top of the lifting and rotating structure 4, it is blocked by the stop block 32. 2. The lifting and rotating structure 4 operates. The first cylinder 412 of the lifting component 41 drives the lifting plate 413 to rise, which drives the rotating component 42 and the rotating table 43 to rise synchronously. The rotating table 43 lifts the entire stack of pallets to a set height. Then the rotating component 42 operates. The first motor 421 drives the rotating shaft 425 to rotate through the first driving wheel 422, the first driven wheel 423 and the first belt 424. Then it drives the rotating table 43 to rotate 90°, rotating the entire stack of pallets from the left and right position along the length direction to the front and back position. Finally, the lifting component 41 operates. The piston rod of the first cylinder 412 descends and places the entire stack of pallets on the first double track belt line 1. 3. The entire stack of pallets is conveyed to the second double-track belt conveyor 2 via the first double-track belt conveyor 1, and then conveyed to the left side of the baffle 53 of the pallet limiting structure 5 via the second double-track belt conveyor 2. At this time, the blocking sheet metal 542 of the blocking component 54 is in the rising blocking state, and the guide plate 51 is in the belt state away from the second double-track belt conveyor 2. Then, the two second cylinders 52 drive the two guide plates 51 to move towards each other, blocking the left side of the entire stack of pallets and forming a limiting state. Fourth, the pallet assembly 7 is activated. Both pallet assemblies 7 are driven by the fourth cylinder 72 to move the pallet 73. The two pallets 73 are inserted under the second to last pallet in the stack of pallets, and the pallet and all the pallets above it are lifted up by the height of one pallet 73, so that the second to last pallet and the second pallet are separated. 5. When the pushing structure 6 is activated, the horizontal drive structure 62 starts. Through the combined action of the second motor 621, the second drive wheel 622, the second driven wheel 623, and the second belt 624, the push rods 634 of the two push rod assemblies 63 are driven to move to the right. The push rod 634 contacts the bottommost pallet in the stack of pallets and pushes the pallet to the right. At the same time, the third cylinder 541 of the blocking assembly 54 drives the blocking sheet metal 542 to descend, no longer obstructing the pallet, ensuring that the pallet pushed by the push rod 634 is no longer blocked, and completing the sequential feeding of a single pallet.
