[0002] Currently, in the technical field of logistics transportation, the loading and unloading operation of goods on the platform is an important link connecting upstream warehousing and downstream transportation. However, most of the loading and unloading operations of goods on the platform are still mainly manual, which is time-consuming and laborious, with poor loading and unloading efficiency, and there are also problems such as high cargo damage rate and insecurity.

[0003] Traditional goods lifting and transfer equipment usually divides the lifting, transfer, and stacking of goods into different stages. Each stage may require different equipment or manual intervention. Lifting and palletizing need to be operated in sections, the process is fragmented, the inclination angle of the goods needs to be manually adjusted during transfer, and each piece needs to be lifted one by one, with a long action cycle. At the same time, during the stacking process of goods, there may be problems such as misalignment and uneven stacking of goods, and instability or inclination may occur when the stacking height increases. It operates intermittently, relies on manual calibration, and has a slow processing speed. Especially when the weight of the stacked goods increases, the stability of the equipment may be affected. Traditional equipment usually requires manual intervention for adjustment or monitoring operations. Summary of the Invention

[0015] The present invention provides a cargo lifting and stacking automatic transfer device, which has the following beneficial effects: 1. The present invention has a space-intensive layout: the bottom frame and the top frame are staggered and installed, and the top frame is installed on the side of the bottom frame to form a top angle area, which not only avoids the vertical overlap of the double frames and occupies space, but also provides a lifting buffer space for the lifting and stacking mechanism, so that the overall volume of the equipment is reduced. The input guide roller group is embedded in the side wall of the bottom frame, and the goods are directly introduced into the receiving guide roller mechanism from the external conveyor line, reducing the lateral extension space requirements of traditional transfer equipment.

[0016] 2. The present invention has the capability of continuous and efficient transportation: the driving chain circulates along the elliptical rack, driving multiple sets of reciprocating lifting mechanisms to operate continuously, realizing uninterrupted operation of the entire process from receiving, lifting to palletizing of goods. The efficiency is improved compared with traditional single lifting equipment. Multiple sets of reciprocating lifting mechanisms are distributed at intervals, and each set of mechanisms independently completes the lifting of goods, forming a "receiving-lifting-releasing" assembly line operation.

[0017] 3. The present invention has dynamic height adjustment and stacking stability: the lifting and stacking mechanism controls the lifting and lowering of the parcel linkage frame through the screw output structure, can adjust the transfer height in real time, adapt to the buffering and constant pressure output of the scissor-type bracket required for different stacking heights, and the scissor-type bracket and the retaining spring of the step-by-step descending assembly work together to make the output guide roller group sink at a uniform speed when the goods are stacked, buffering the impact force of the falling goods and avoiding the stacking from tipping over.

[0018] 4. The present invention has the ability of precise positioning and adaptive alignment: the inclined surface design of the trapezoidal guide frame in the receiving guide roller mechanism allows the input goods to be automatically aligned to one side of the guide roller frame and gathered into rows, eliminating the need for manual adjustment. The lifting rollers of the reciprocating lifting mechanism are accurately embedded in the gap of the guide roller frame to avoid deviation or jamming during the lifting process of the goods.

[0019] 5. The present invention has the functions of mechanism linkage and intelligent reset: the conical resistance block of the lifting and stacking mechanism contacts the traction link at a specific height, forcing the lifting roller to tilt and guide the goods to slide into the central inclined platform, realizing the automatic switching of "horizontal lifting → inclined unloading", and the quick reset system driven by the retaining spring. After the traction link is separated from the conical resistance block, the retaining spring drives the linkage rod to reset to a horizontal state, thereby ensuring the continuity of the next cycle of operation.

[0020] 6. The present invention has modularity and maintainability: the core components such as the bottom frame, the top frame, and the guide roller frame are connected by bolts, which support quick disassembly and replacement. The independent drive unit layout, the drive chain, the screw output structure, the scissor-type bracket and other power units operate independently in different areas to avoid mechanical interference.

[0024] Please refer to the attached Figure 1 -Attached Figure 3, an embodiment of the present invention provides an automatic transfer device for lifting and palletizing goods, including: a bottom frame 1 for fixing and bearing the structure of the automatic transfer device for lifting and palletizing goods, a top frame 2 and an elliptical storage rack 3 are located on the bottom frame 1 for installing a driving chain condition 4 and a lifting and palletizing mechanism 8.

The reciprocating lifting mechanism 7 is distributed on the elliptical storage rack 3 and extends into the top frame 2. The lifting and palletizing mechanism 8 is movably arranged on the top frame 2 and is close to one side of the receiving roller mechanism 6. This device is mainly aimed at the lifting and transfer operation in goods transportation. At the same time, during the lifting and transfer process, palletizing and stacking operations can be carried out synchronously. The overall structure is installed according to the bottom frame 1 and the top frame 2, and the top frame 2 is installed on one side of the bottom frame 1, so that an included angle area can be left on the top of the bottom frame 1. The elliptical storage rack 3 that restricts the operation of the driving chain condition 4 is installed in series on the outside of the top frame 2, so that the driving chain condition 4 can operate inside the top frame 2 through the elliptical storage rack 3. The input roller group 5 as the goods input is installed on the side wall of the bottom frame 1 and can guide the goods to be transferred onto the receiving roller mechanism 6 inside the bottom frame 1. The multiple groups of reciprocating lifting mechanisms 7 installed at the chain end of the driving chain condition 4 can follow the operation of the driving chain condition 4 synchronously. At the same time, the lifting and palletizing mechanism 8 that moves up and down along the outer surface of the top frame 2 itself can drive the reciprocating lifting mechanism 7 to change its shape, so as to guide the goods into the lifting and palletizing mechanism 8, and then carry out lifting and stacking transfer through the lifting and palletizing mechanism 8.

[0025] Please refer to the attached Figure 1 - attached Figure 6, the receiving roller mechanism 6 is located on the elliptical storage rack 3 and is used to receive and linearly guide the goods to be transported. The receiving roller mechanism 6 includes a side frame 61 and a roller frame 62. The side frame 61 is fixedly connected to the side of the bottom frame 1 away from the elliptical storage rack 3. The roller frames 62 are rotatably connected to the side frame 61 at equal intervals. At the same time, a single-side bracket structure is provided at the other end and is installed on the bottom frame 1. A trapezoidal guiding frame 63 is fixedly connected to the side wall of the side frame 61 facing the roller frame 62. The inclined surface of the trapezoidal guiding frame 63 faces the input roller group 5. The transmission structure of the roller frame 62 is arranged inside the side frame 61. The side frame 61 included in the receiving roller mechanism 6 is installed on the side of the bottom frame 1 away from the elliptical storage rack 3, so that the elliptical storage rack 3 and the drive chain condition 4 fixed on the top frame 2 can operate in an independent area. The other ends of multiple groups of roller frames 62 added to the side frame 61 are installed on the bottom frame 1 through independent bracket structures, so that the gap areas between adjacent roller frames 62 are open. The trapezoidal guiding frame 63 added to the side frame 61 is attached to the surface of the roller frame 62, and its inclined surface can guide the goods fed by the input roller group 5 to align and approach the side of the roller frame 62, and gradually gather into rows on the side of the roller frame 62 close to the elliptical storage rack 3.

[0026] Please refer to the appendix Figure 1 - appendix Figure 10, the reciprocating lifting mechanism 7 is located on the driving chain condition 4 and cooperates with the guide roller frame 62 to continuously lift the goods to be transported in a reciprocating manner. The reciprocating lifting mechanism 7 includes an opposed linkage frame 71 and a linkage shaft rod 72. The opposed linkage frame 71 is an L-shaped protruding structure with a clamping shaft structure on one side and is adjacent to the linkage shaft rod 72 for installation. At both ends of the clamping shaft structures of the opposed linkage frame 71 and the linkage shaft rod 72, clamping angle members 73 are fixedly connected. The adjacent clamping angle members 73 are connected by chain links. The opposed linkage frame 71 and the linkage shaft rod 72 are fitted on the chain shaft of the driving chain condition 4 through the clamping angle members 73. A horizontal connecting rod 74 is connected between the clamping shaft structure of the opposed linkage frame 71 and the linkage shaft rod 72. A linkage fixed shaft 75 is rotatably embedded on the side of the opposed linkage frame 71 away from the clamping shaft structure. At both ends of the linkage fixed shaft 75, opposed linkage rods 76 are fixedly connected. On the side of the opposed linkage frame 71 facing the opposed linkage rods 76, a limiting strip structure is fixedly connected at right angles. The opposed linkage rods 76 are provided with a chute structure. Both sides of the traction connecting rod 77 are rotatably connected to the protruding end corners of the opposed linkage frame 71 on the side of the linkage fixed shaft 75. The end of the traction connecting rod 77 away from the opposed linkage frame 71 is fitted and slides in the chute structure of the opposed linkage rod 76, and a snap spring structure is provided between it and the inner wall of the opposed linkage rod 76. The lifting rollers 78 are equidistantly distributed and fixedly connected to the outer side wall of the linkage fixed shaft 75. The lifting rollers 78 are distributed between adjacent guide roller frames 62. An extension roller structure is embedded at the end of the lifting roller 78 away from the linkage fixed shaft 75. The reciprocating lifting mechanism 7 includes adjacent opposed linkage frames 71 and linkage shaft rods 72. The clamping shaft structures of the opposed linkage frames 71 and the clamping angle members 73 added at both ends of the linkage shaft rods 72 are connected to each other through a chain link structure. When the clamping angle members 73 are installed on the chain of the driving chain condition 4, they can be bent according to the turning part of the chain, so that the clamping angle members 73 can pull the opposed linkage frame 71 and the linkage shaft rod 72 to follow the displacement of the chain end of the driving chain condition 4. The horizontal connecting rod 74 sleeved between the linkage shaft rod 72 and the clamping shaft structure of the opposed linkage frame 71 enables the opposed linkage frame 71 and the linkage shaft rod 72 to be lifted to a horizontal state along the linkage shaft rod 72 when they follow the clamping angle members 73 to displace to the vertical end of the chain structure of the driving chain condition 4, so that when the opposed linkage frame 71 vertically displaces, it always maintains a horizontal rise. The linkage fixed shaft 75 added to the outer end of the opposed linkage frame 71 installs and fixes multiple groups of distributed lifting rollers 78 according to the gap area between the guide roller frames 62. The opposed linkage rods 76 added at both ends of the linkage fixed shaft 75 are suspended by the traction connecting rods 77 added at the protruding ends of the opposed linkage frame 71. While the traction connecting rods 77 are installed on the opposed linkage frame 71, the other ends slide and are embedded in the chute structure of the opposed linkage rods 76, and a snap spring structure that can be reset and driven is embedded. At the same time, a balanced limiting strip is added according to the rotation trajectory of the opposed linkage rods 76 to limit the excessive rotation of the opposed linkage rods 76.The opposed linkage rods 76 distributed at both ends of the linkage fixed shaft 75 can be rotated and lifted flat by the traction link 77, and the lifting rollers 78 fixed on the linkage fixed shaft 75 can also rise or fall in a horizontal state when following the displacement of the drive chain condition 4. When a set of reciprocating lifting mechanisms 7 reaches below the receiving guide roller mechanism 6 along the drive chain condition 4, the lifting rollers 78 included therein will simultaneously be inserted into the adjacent gaps between the guide roller frames 62 and lift the goods gathered in rows on the lifting guide roller frames 62. By analogy, multiple sets of reciprocating lifting mechanisms 7 installed on the drive chain condition 4 can reciprocally lift the goods gathered by the guide roller frames 62 until the reciprocating lifting mechanism 7 rises to a specific height of the lifting and palletizing mechanism 8. When the lifting and palletizing mechanism 8 is adjusted to the required transfer height, the reciprocating lifting mechanism 7 holding the goods will approach the height of the center inclined platform 84 and the conical abutting block 83 along with the drive chain condition 4. When the traction link 77 rises and touches the conical abutting block 83, the stationary conical abutting block 83 will drive the traction link 77 to rotate and press down along the opposed linkage frame 71, and push the opposed linkage rod 76 and the linkage fixed shaft 75 to rotate and press down along the chute of the opposed linkage rod 76. When the lifting roller 78 that holds the goods and is fixed on the linkage fixed shaft 75 reaches the center inclined platform 84, it will rotate along with the linkage fixed shaft 75 and form a certain slope, driving the goods held in a row to synchronously enter the center inclined platform 84 along the lifting roller 78. The conical abutting block 83 can adjust different abutting heights along with the lifting frame 81, so that the triggering of the inclined state of the reciprocating lifting mechanism 7 can change along with the height of the lifting and palletizing mechanism 8. When the traction link 77 moves away from the conical abutting block 83, the snap ring structure installed between the traction link 77 and the chute of the opposed linkage rod 76 will drive the traction link 77 to reset and re-level.

[0027] Please refer to the appendix Figure 1 - Appendix Figure 13The lifting and stacking mechanism 8 is located on the elliptical storage rack 3, and cooperates with the screw output structure of the top rack 2, the side frame 61, the traction connecting rod 77 and the lifting roller 78 to receive and stack the goods to be transferred. The lifting and stacking mechanism 8 includes a lifting frame 81, a parcel linkage frame 82, an output guide roller group 86 and a step-by-step descending component. The lifting frame 81 is fixedly connected to the side of the parcel linkage frame 82 close to the receiving guide roller mechanism 6, and the parcel linkage frame 82 is sleeved and slid on the outer surface of the top rack 2. The top of the lifting frame 81 close to the parcel linkage frame 82 is fixedly connected with a centering inclined platform 84, and the inclined plate structure of the centering inclined platform 84 is provided with through grooves corresponding to the distribution of the lifting rollers 78. The side of the lifting frame 81 away from the parcel linkage frame 82 is fixedly connected with a positioning slide 85, and the output guide roller group 86 slides inside the lifting frame 81 through the positioning slide 85 and is located in the output direction of the central inclined platform 84. The step-by-step descending components are distributed on the side wall of the lifting frame 81 away from the wrapping linkage frame 82. An internal threaded sleeve structure is provided on one side of the wrapping linkage frame 82, and is threadedly sleeved on the screw output structure of the top frame 2. The inner wall of the wrapping linkage frame 82 is also located on the displacement trajectory of the traction link 77 and is fixedly connected with conical abutment blocks 83 on both sides opposite to each other. The step-by-step descending components include a plurality of groups of mutually hinged scissor-type brackets 87. The top end of the top scissor-type bracket 87 is relatively slidably embedded in the top wall of the lifting frame 81, and the bottom end of the bottom scissor-type bracket 87 is relatively slidably embedded in the side wall of the output guide roller group 86. The cross-end points of the scissor-type brackets 87 are rotatably connected with extension tables 88. A retaining spring structure is connected between adjacent extension platforms 88, and the lifting and stacking mechanism 8 includes a lifting frame 81 installed on the transfer structure and a parcel linkage frame 82 for the lifting and stacking mechanism 8 to lift and move itself. The lifting frame 81 is fixed on the parcel linkage frame 82 and embedded in the angle area reserved at the top of the bottom frame 1, and the parcel linkage frame 82 itself is sleeved on the outer surface of the top frame 2. At the same time, the internal threaded sleeve structure installed on the parcel linkage frame 82 is docked with the screw output structure installed on the top frame 2. When the screw output structure is in operation, the parcel linkage frame 82 and the lifting frame 81 itself can be controlled to rise or fall along the top frame 2 to change different transfer heights, and the side wall of the lifting frame 81 facing the top frame 2 is equipped with a central inclined platform 8 that can guide the transportation of goods. 4, its own guiding inclined plate structure is equipped with multiple groups of through grooves for the lifting rollers 78 to pass through according to the distribution displacement of the lifting rollers 78, and the inner side of the lifting frame 81 is equipped with conical abutment blocks 83 opposite to each other on both sides according to the installation height of the central inclined platform 84 and the displacement trajectory of the traction link 77. When the lifting and stacking mechanism 8 is adjusted to the required transfer height, the reciprocating lifting mechanism 7 that lifts the goods will follow the driving chain condition 4 to approach the height of the central inclined platform 84 and the conical abutment block 83. When the traction link 77 rises and touches the conical abutment block 83, the stationary conical abutment block 83 will drive the traction link 77 to rotate and press down along the opposite linkage frame 71, and push the opposite linkage rod 76 and the linkage fixed shaft 75 to rotate and press down along the slide groove of the opposite linkage rod 76.When the lifting roller 78 that holds up the goods and is fixed on the linkage fixed shaft 75 reaches the centering ramp 84, it will rotate along with the linkage fixed shaft 75 and form a certain slope, driving the goods held up in a row to synchronously enter the centering ramp 84 along the lifting roller 78. The conical contact block 83 can adjust different contact heights along with the lifting frame 81, so that the triggering of the inclination state of the reciprocating lifting mechanism 7 can change along with the height of the lifting and palletizing mechanism 8. After the traction link 77 moves away from the conical contact block 83, the snap ring structure installed between the traction link 77 and the chute of the opposed linkage rod 76 will drive the traction link 77 to reset and rebalance. The goods transferred in a row to the centering ramp 84 will continue to enter the lifting frame 81 along the centering ramp 84 and finally fall on the guide roller area of the output guide roller group 86 that moves up and down along the positioning slide 85 inside the lifting frame 81. The output guide roller group 86 is also responsible for transporting the stacked goods. With the cyclic lifting of multiple sets of reciprocating lifting mechanisms 7, goods in different rows start to stack and palletize on the output guide roller group 86. As the weight of the received goods on the output guide roller group 86 increases, under the limitation of the gradually descending components included in the lifting and palletizing mechanism 8, the output guide roller group 86 starts to gradually descend to cooperate with the continuously stacked goods. The gradually descending components include multiple sets of mutually articulated scissor brackets 87. A snap ring structure is fixed between two adjacent scissor brackets 87 on the extension platform 88 installed at the hinge point of the scissor brackets 87. The top scissor bracket 87 is installed on the top wall of the lifting frame 81, and the bottom scissor bracket 87 is suspended and installed on the output guide roller group 86. When the output guide roller group 86 continuously descends along the positioning slide 85 due to the increasing stacking height, the mutually articulated scissor brackets 87 start to expand along the lifting frame 81 and the output guide roller group 86 at the same time, and the snap ring structure between the extension platforms 88 is also pulled accordingly, so that the output guide roller group 86 can slowly descend, and at the same time, it also increases the buffering force for the goods to fall and palletize. Until the goods stacked and palletized by itself are transported away, multiple sets of snap ring structures that lose the pulling force will start to pull the extension platforms 88 and the configured scissor brackets 87 to contract, and pull the output guide roller group 86 back to the output port position of the centering ramp 84.,

[0028] Working principle: First of all, this device is mainly aimed at the lifting and transfer operations in cargo transportation. At the same time, during the lifting and transfer process, palletizing and stacking operations can be carried out synchronously. The overall structure is installed according to the bottom frame 1 and the top frame 2, and the top frame 2 is installed on one side of the bottom frame 1, so that an included angle area can be retained at the top of the bottom frame 1. The elliptical storage rack 3 that restricts the operation of the drive chain condition 4 is installed in series on the outside of the top frame 2, so that the drive chain condition 4 can operate inside the top frame 2 through the elliptical storage rack 3. The input guide roller group 5 for cargo input is installed on the side wall of the bottom frame 1, and can guide the cargo to be transferred onto the receiving guide roller mechanism 6 inside the bottom frame 1. The multiple reciprocating lifting mechanisms 7 installed at the chain end of the drive chain condition 4 can operate synchronously following the drive chain condition 4. At the same time, the lifting and palletizing mechanism 8 that moves up and down along the outer surface of the top frame 2 can drive the reciprocating lifting mechanism 7 to change its shape by itself, so as to guide the cargo into the lifting and palletizing mechanism 8, and then the cargo is lifted and stacked and transferred through the lifting and palletizing mechanism 8. First of all, the side frame 61 included in the receiving guide roller mechanism 6 is installed on one side of the bottom frame 1 away from the elliptical storage rack 3, so that the elliptical storage rack 3 and the drive chain condition 4 fixed on the top frame 2 can operate in an independent area. The other ends of the multiple guide roller frames 62 installed on the side frame 61 are installed on the bottom frame 1 through an independent bracket structure, so that the gap area between adjacent guide roller frames 62 is open. The trapezoidal guide frame 63 installed on the side frame 61 is attached to the surface of the guide roller frame 62, and its inclined surface can guide the cargo fed by the input guide roller group 5 to align and approach one side of the guide roller frame 62, and gradually gather into rows on the side of the guide roller frame 62 close to the elliptical storage rack 3. The reciprocating lifting mechanism 7 includes opposed linkage frames 71 and linkage shafts 72 arranged adjacent to each other. The clamping shaft structure of the opposed linkage frame 71 and the clamping angle parts 73 installed at both ends of the linkage shaft 72 are connected to each other through a link structure. When the clamping angle parts 73 are installed on the chain of the drive chain condition 4, they can be bent according to the turning part of the chain, so that the clamping angle parts 73 can pull the opposed linkage frames 71 and the linkage shafts 72 to displace along with the chain end of the drive chain condition 4. The horizontal connecting rod 74 sleeved between the clamping shaft structure of the linkage shaft 72 and the opposed linkage frame 71 enables the opposed linkage frames 71 and the linkage shafts 72 to be lifted to a horizontal state along the linkage shaft 72 when they are displaced to the vertical end of the chain structure of the drive chain condition 4 following the clamping angle parts 73, so that when the opposed linkage frame 71 is vertically displaced, it always rises horizontally. The linkage fixed shafts 75 installed at the outer ends of the opposed linkage frames 71 fix multiple distributed lifting rollers 78 according to the gap area between the guide roller frames 62. The opposed linkage rods 76 installed at both ends of the linkage fixed shafts 75 are suspended by the traction connecting rods 77 installed at the protruding ends of the opposed linkage frames 71. While the traction connecting rods 77 are installed on the opposed linkage frames 71, the other ends slide into the chute structures of the opposed linkage rods 76 and are embedded with a reset-driven snap spring structure.Meanwhile, a trimming limit bar is installed according to the rotation trajectory of the opposed linkage rod 76 to limit the excessive rotation of the opposed linkage rod 76, so that the opposed linkage rods 76 distributed at both ends of the linkage fixed shaft 75 can be rotated and lifted flat by the traction link 77. The lifting rollers 78 fixed on the linkage fixed shaft 75 can also rise or fall in a horizontal state when following the drive chain condition 4. When a set of reciprocating lifting mechanism 7 reaches below the receiving guide roller mechanism 6 along the drive chain condition 4, the lifting rollers 78 it contains will simultaneously be embedded into the adjacent gaps between the guide roller frames 62 and lift the goods gathered in rows on the lifting guide roller frame 62. By analogy, multiple groups of reciprocating lifting mechanisms 7 installed on the drive chain condition 4 can reciprocally lift the goods gathered by the guide roller frame 62 until the reciprocating lifting mechanism 7 rises to a specific height of the lifting and palletizing mechanism 8. The lifting and palletizing mechanism 8 includes a lifting frame 81 installed with a transfer structure and a package linkage frame 82 for the self-lifting and displacement of the lifting and palletizing mechanism 8 itself. The lifting frame 81 is fixed on the package linkage frame 82 and is embedded into the included angle area left at the top of the bottom frame 1. The package linkage frame 82 itself is sleeved on the outer surface of the top frame 2. At the same time, the internally threaded sleeve structure installed on the package linkage frame 82 is docked with the screw output structure installed on the top frame 2. When the screw output structure operates, it can control the package linkage frame 82 and the structure of the lifting frame 81 itself to rise or fall along the top frame 2 to change different transfer heights. A centered inclined platform 84 for guiding the goods conveyance is installed on the side wall of the lifting frame 81 facing the top frame 2. According to the distribution displacement of the lifting rollers 78, multiple through slots for the lifting rollers 78 to pass through are installed on its guiding inclined plate structure. On the inner side of the lifting frame 81, two oppositely arranged conical abutting blocks 83 are installed according to the installation height of the centered inclined platform 84 and the displacement trajectory line of the traction link 77. When the lifting and palletizing mechanism 8 is adjusted to the required transfer height, the reciprocating lifting mechanism 7 that holds the goods will approach the heights of the centered inclined platform 84 and the conical abutting blocks 83 along the drive chain condition 4. When the traction link 77 rises and touches the conical abutting block 83, the static conical abutting block 83 will drive the traction link 77 to rotate and press down along the opposed linkage frame 71, and push the opposed linkage rod 76 and the linkage fixed shaft 75 to rotate and press down along the chute of the opposed linkage rod 76. When the lifting roller 78 that holds the goods and is fixed on the linkage fixed shaft 75 reaches the centered inclined platform 84, it will rotate along with the linkage fixed shaft 75 and form a certain slope, driving the goods lifted in a row to synchronously enter the centered inclined platform 84 along the lifting roller 78. The conical abutting block 83 can adjust different abutting heights along with the lifting frame 81, so that the triggering of the inclined state of the reciprocating lifting mechanism 7 can change along with the height of the lifting and palletizing mechanism 8. After the traction link 77 moves away from the conical abutting block 83, the snap spring structure installed between the traction link 77 and the chute of the opposed linkage rod 76 will drive the traction link 77 to reset and re-trim. The goods transferred in a row to the centered inclined platform 84 will continue to enter the lifting frame 81 along the centered inclined platform 84,And finally fall within the lifting frame 81 along the guiding roller area of the output guiding roller group 86 that moves up and down along the positioning slide 85. The output guiding roller group 86 is also responsible for transporting the stacked goods. With the cyclic lifting of multiple sets of reciprocating lifting mechanisms 7, goods in different rows start to be stacked and palletized on the output guiding roller group 86. As the weight of the received goods on the output guiding roller group 86 increases, under the limitation of the gradually descending component included in the lifting and palletizing mechanism 8, it starts to gradually descend to cooperate with the continuously stacked and palletized goods. The gradually descending component includes multiple sets of mutually articulated scissor brackets 87. An extension platform 88 installed at the articulated point of the scissor brackets 87 fixes a set of snap spring structures between two adjacent scissor brackets 87. The top scissor bracket 87 is installed on the top wall of the lifting frame 81, and the bottom scissor bracket 87 is suspended and installed on the output guiding roller group 86. When the output guiding roller group 86 continuously descends along the positioning slide 85 due to the increase in stacking height, the mutually articulated scissor brackets 87 start to unfold along the lifting frame 81 and the output guiding roller group 86 at the same time, and the snap spring structures between the extension platforms 88 are also pulled accordingly, enabling the output guiding roller group 86 to descend slowly and increasing the buffering force for the goods to fall and be palletized. Until the goods stacked and palletized by itself are transported, multiple sets of snap spring structures that lose the pulling force will start to pull and contract the extension platforms 88 and the configured scissor brackets 87, and pull and guide the output guiding roller group 86 back to the output port position of the central inclined platform 84.,
