[0009] By adopting the above technical solution, when the feeding mechanism places the aluminum profile on the limit frame, the aluminum profile can be located between the fixed limit plate and the movable limit plate. At the same time, the elastic connection component can tighten the movable limit plate, which helps the movable limit plate to cooperate with the fixed limit plate to limit and fix the aluminum profile, thereby avoiding the aluminum profile from being deflected when being transported on the conveyor belt, and facilitating the subsequent material moving mechanism to clamp the aluminum profile on the conveyor belt and place it on the placement frame.

When the rotating part stops rotating, the limiting assembly can cooperate with the grooves on the side wall of the aluminum profile to limit the aluminum profile, helping to limit it according to the shape of the aluminum profile and facilitate the subsequent material transfer mechanism to clamp the aluminum profile on the conveyor belt and place it on the placement frame.

Once the multiple first clamping jaws have completed clamping the aluminum profile, the lifting seat and the electric push rod cooperate to drive the clamped aluminum profile to move above the conveyor belt and transfer the aluminum profile to the limit frame on the conveyor belt, completing the aluminum profile loading process.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-9 This application is described in further detail.

[0041] Example 1:

[0042] The present application discloses an automatic stacking device for aluminum profiles. Figure 1 and Figure 2 , including a frame 1, a feeding mechanism 4 is provided at the feeding end of the frame 1, and two conveyor belts 2 are fixedly installed on one side of the frame 1 near the feeding mechanism 4. The feeding mechanism 4 includes a feeding rack 41, and the feeding rack 41 includes a support rod 411, a discharge rod 412 and a separator rod 413. There are two support rods 411 and two discharge rods 412, and they are one-to-one corresponding. The two support rods 411 are fixedly connected to the side wall of the frame 1, and each discharge rod 412 is fixedly connected to the top of the corresponding support rod 411. The separator rod 413 is fixedly connected to the two discharge rods 412.

[0043] Reference Figure 1 and Figure 2The feeding mechanism 4 also includes a feeding assembly 42, which includes a lifting seat 421, an electric push rod 422, a first clamping jaw 423, and a movable seat 424. The electric push rod 422 is fixedly mounted within the frame 1. The lifting seat 421 includes a base plate and a lifting plate. The base plate is fixedly connected to the output end of the electric push rod 422 and is slidably mounted within the frame 1. A lifting cylinder is fixed to the base plate, and the lifting plate is fixedly connected to the piston rod of the lifting cylinder and is located above the base plate. In this embodiment, two movable seats 424 are provided, and the two movable seats 424 are respectively slidably connected to the ends of the lifting plate; a driving member 425 is fixedly mounted on the side wall of each movable seat 424. In this embodiment, the driving member 425 is a drive motor; in this embodiment, a total of four first clamping jaws 423 are provided, and each two first clamping jaws 423 are fixedly connected to the top of a movable seat 424.

[0044] The two aluminum profiles 13 are placed on either side of the separator rod 413 on the discharge rod 412. The electric push rod 422 drives the bottom plate and the lifting plate to slide horizontally, thereby driving the two movable seats 424 to slide horizontally, so that the multiple first clamping jaws 423 on the two movable seats 424 approach the ends of the two aluminum profiles 13. The two drive motors operate synchronously, driving the two movable seats 424 to slide toward each other along the length of the lifting plate toward the center of the lifting plate. The movable seats 424 are perpendicular to the horizontal sliding direction of the lifting plate, so that the four first clamping jaws 423 clamp the ends of the two aluminum profiles 13. After the clamping is completed, the lifting cylinder pushes the lifting plate to rise, thereby driving the aluminum profile 13 to rise, and the electric push rod 422 then drives the lifting seat 421 to move horizontally above the conveyor belt 2. Finally, the lifting cylinder drives the lifting plate to descend, thereby driving the two movable seats 424 and the four first clamps 423 to descend, and then driving the aluminum profile 13 to descend. The four first clamps 423 are released, and the aluminum profile 13 can be transferred to the conveyor belt 2 for transportation, completing the loading.

[0045] Reference Figure 1 and Figure 3 Each conveyor belt 2 is provided with multiple sets of limiting mechanisms 3, each limiting mechanism 3 includes a limiting frame 31, a fixed limiting plate 32, a movable limiting plate 33 and an elastic connection component 34, the limiting frame 31 is fixedly connected to the conveyor belt 2, the fixed limiting plate 32 is fixedly connected to the outer wall of the limiting frame 31, the elastic connection component 34 is arranged in the limiting frame 31, and the movable limiting plate 33 is connected to the limiting frame 31 through the elastic connection component 34.

[0046] Reference Figure 3 and Figure 4The elastic connection assembly 34 includes a telescopic rod 341 and a tension spring 342. The telescopic rod 341 includes a fixed portion 3411 and a movable portion 3412. The fixed portion 3411 is fixedly connected to the limit frame 31. One end of the movable portion 3412 is movably connected within the fixed portion 3411. The end of the movable portion 3412 away from the fixed portion 3411 is fixedly connected to the movable limit plate 33. The tension spring 342 is sleeved around the movable portion 3412. One end of the tension spring 342 is fixedly connected to the fixed portion 3411. The end of the tension spring 342 away from the fixed portion 3411 is fixedly connected to the movable limit plate 33. A slot 35 is defined on the side wall of the limit frame 31 facing away from the fixed limit plate 32. The slot 35 extends toward the fixed limit plate 32.

[0047] When the first clamping jaw 423 clamps the aluminum profile 13 onto the conveyor belt 2, it places the aluminum profile 13 onto the limiting frame 31, positioning the aluminum profile 13 between the fixed limiting plate 32 and the movable limiting plate 33. Simultaneously, the tension spring 342, under its own elastic force, tends to contract, driving the movable limiting plate 33 to cooperate with the fixed limiting plate 32 to limit and secure the aluminum profile 13. This minimizes deflection of the aluminum profile 13 during transport on the conveyor belt 2 and improves the stability of the aluminum profile 13 during transport on the conveyor belt 2. The slots 35 accommodate the fixed limiting plates 32 on adjacent limiting frames 31, helping to increase the compactness between multiple limiting frames 31 on the conveyor belt 2, thereby improving the transport efficiency of the aluminum profile 13.

[0048] Reference Figure 3 and Figure 4 A plurality of guide rods 9 are fixed to the inner wall of the limit frame 31, and a plurality of guide holes 10 are defined in the bottom sidewall of the movable limit plate 33. Each guide rod 9 is inserted into a guide hole 10 at one end thereof, located closest to the movable limit plate 33. The plurality of guide rods 9 ensures that the minimum distance between the movable limit plate 33 and the fixed limit plate 32 is greater than or equal to the bottom width of the aluminum profile 13, thereby ensuring that the aluminum profile 13 can fit between the movable limit plate 33 and the fixed limit plate 32. When the movable limit plate 33 moves, the plurality of guide rods 9 guide the movable limit plate 33, thereby improving the stability of the movable limit plate 33 during movement.

[0049] Reference Figure 1 and Figure 5, fixed frames 14 are fixedly installed on both sides of the frame 1, and a material moving mechanism 6 is provided on the fixed frame 14. The material moving mechanism 6 includes a movable frame 61, a translation drive device 62 and a clamping assembly 63. The translation drive device 62 is movably installed on the fixed frame 14, and the movable frame 61 is fixedly installed on the translation drive device 62. The clamping assembly 63 includes a driving cylinder 631, a mounting frame 632 and a plurality of second clamping claws 633. A cover 611 is fixedly installed on the movable frame 61, the driving cylinder 631 is fixedly installed inside the cover 611, the mounting frame 632 is fixedly connected to the output end of the driving cylinder 631, and the plurality of second clamping claws 633 are fixedly installed on the bottom surface of the mounting frame 632. A plurality of lifting cylinders 15 are fixed on the inner wall of the frame 1, and the output ends of the plurality of lifting cylinders 15 are fixedly connected to the placement frame 5. The placement frame 5 is arranged adjacent to the two conveyor belts 2.

[0050] When the aluminum profile 13 is transported to the corresponding position by the conveyor belt 2, the output end of the driving cylinder 631 extends, driving the mounting frame 632 to move downward, thereby causing the multiple second clamps 633 to move downward to clamp the aluminum profile 13 on the conveyor belt 2. After the multiple second clamps 633 complete the clamping, the output end of the driving cylinder 631 contracts, driving the multiple second clamps 633 and the aluminum profile 13 to rise, and the translation drive device 62 drives the movable frame 61 to move above the placement frame 5. The output end of the driving cylinder 631 extends, driving the multiple second clamps 633 and the aluminum profile 13 to descend. When the aluminum profile 13 contacts the placement frame 5, the multiple second clamps 633 release their grip on the aluminum profile 13, allowing the aluminum profile 13 to be placed on the placement frame 5, facilitating the subsequent stacking of the aluminum profile 13.

[0051] Reference Figure 1 A stacking tray 7 is fixedly placed on one side of the frame 1, and a stacking device 8 is fixedly installed between the frame 1 and the stacking tray 7. When the aluminum profile 13 is clamped onto the placement frame 5, the output ends of multiple lifting cylinders 15 are synchronously extended, thereby lifting the placement frame 5. After the placement frame 5 is lifted, the stacking device 8 clamps the aluminum profile 13 on the placement frame 5 and stacks it onto the stacking tray 7, which facilitates the automatic stacking of the aluminum profiles 13 and improves the stacking efficiency of the aluminum profiles 13.

[0052] The working principle of the embodiment of the present application is as follows: the aluminum profile 13 is placed on both sides of the separator rod 413 on the discharge rod 412, and the electric push rod 422 drives the lifting seat 421 to move, so that the movable seat 424 drives the first clamping jaw 423 to approach the end of the aluminum profile 13. When the first clamping jaw 423 stops moving, the first clamping jaw 423 can clamp the end of the aluminum profile 13. After clamping is completed, the lifting seat 421 drives the movable seat 424 to rise, thereby driving the aluminum profile 13 to rise. The electric push rod 422 then drives the lifting seat 421 to move horizontally above the conveyor belt 2. Finally, the lifting seat 421 drives the movable seat 424 to descend, and the first clamping jaw 423 is released, and the aluminum profile 13 can be transferred to the conveyor belt 2 for transportation.

[0053] When the first clamping jaw 423 clamps the aluminum profile 13 and places it between the fixed limiting plate 32 and the movable limiting plate 33, the tensioning spring 342 drives the movable limiting plate 33 to cooperate with the fixed limiting plate 32 to limit and fix the aluminum profile 13, thereby avoiding the aluminum profile 13 from being deflected when being transported on the conveyor belt 2 as much as possible, and improving the stability of the aluminum profile 13 in being transported on the conveyor belt 2.

[0054] When the aluminum profile 13 is conveyed to the corresponding position on the conveyor belt 2, the driving cylinder 631 drives the multiple second clamps 633 to move downward and clamp the aluminum profile 13. After clamping, the output end of the driving cylinder 631 contracts, driving the multiple second clamps 633 and the aluminum profile 13 to rise. The translation drive device 62 drives the movable frame 61 to move above the placement frame 5. The output end of the driving cylinder 631 extends, driving the multiple second clamps 633 and the aluminum profile 13 to descend, and the aluminum profile 13 is placed on the placement frame 5. The output ends of the multiple lifting cylinders 15 extend synchronously, thereby driving the placement frame 5 to lift. The stacking device 8 clamps the aluminum profile 13 on the placement frame 5 and stacks it on the stacking tray 7, which helps to achieve automatic stacking of the aluminum profiles 13 and improves the stacking efficiency of the aluminum profiles 13.

[0055] Example 2:

[0056] Reference Figure 6 and Figure 7 The embodiment of the present application differs from the first embodiment in that each limiting mechanism 3 includes a connecting frame 36 and two movable plates 37 connected to the connecting frame 36. Each movable plate 37 includes a rotating portion 372 and two second fixed portions 371. The two second fixed portions 371 of one movable plate 37 are fixedly connected to the outer wall of the connecting frame 36, while the two second fixed portions 371 of the other movable plate 37 are fixedly connected to the inner wall of the connecting frame 36. The ends of the two second fixed portions 371 away from the connecting frame 36 are fixedly connected to a connecting rod, which is covered with a torsion spring. The rotating portion 372 is rotatably connected to the connecting rod. An unlocking protrusion 16 is fixed to the bottom end of each second clamping jaw 633.

[0057] Reference Figure 6 and Figure 8 Two sets of supporting assemblies 11 are provided on the connecting frame 36, and the two sets of supporting assemblies 11 are located between the two rotating parts 372. Each set of supporting assemblies 11 includes a vertical plate 111, a connecting spring 112, and a horizontal plate 113. Two sets of interconnected vertical slots 361 and horizontal slots 362 are formed on the top wall of the connecting frame 36. The connecting spring 112 is fixedly mounted on the bottom groove wall of the vertical slot 361. The bottom surface of the vertical plate 111 is fixedly connected to the end of the connecting spring 112 away from the bottom groove wall of the vertical slot 361. The vertical plate 111 is located in the vertical slot 361. The horizontal plate 113 is movably placed in the horizontal slot 362. One end of the horizontal plate 113 abuts the rotating part 372. The end of the horizontal plate 113 away from the rotating part 372 is located in the vertical slot 361 and is wedge-shaped abutted against the bottom end of the vertical plate 111.

[0058] When the first clamping jaw 423 clamps the aluminum profile 13 and places it on the connecting frame 36, the aluminum profile 13 presses the two vertical plates 111 downward, so that the vertical plates 111 move the horizontal plate 113 toward the rotating part 372 during the downward movement, thereby supporting the rotating part 372, so that the rotating part 372 rotates with the connecting rod as the axis in the direction away from the aluminum profile 13.

[0059] Reference Figure 6 and Figure 9 The limiting assembly 12 includes a telescopic plate 121 and an elastic member 122. A placement slot 3721 is defined on the sidewall of the rotating portion 372. A fixed rod is secured to the top end of the placement slot 3721, and the telescopic plate 121 is rotatably connected to the rod. In this embodiment, the elastic member 122 is a rubber spring, which is fixedly mounted within the placement slot 3721 and abuts against the telescopic plate 121. The rubber spring maintains the telescopic plate 121 in a horizontal position.

[0060] As the aluminum profile 13 moves downward to the top surface of the connecting frame 36, the telescopic plate 121 rotates downward under the action of the aluminum profile 13 and compresses the rubber spring, thereby minimizing damage to the telescopic plate 121 caused by the force of the aluminum profile 13. When the rotating portion 372 rotates with the connecting rod as the axis in a direction away from the aluminum profile 13, the telescopic plate 121 rotates upward under the elastic force of the rubber spring, gradually rotating into the groove on the side wall of the aluminum profile 13, so that the telescopic plate 121 and the groove of the aluminum profile 13 are tightly pressed, thereby limiting and fixing the aluminum profile 13. This helps to tighten the telescopic plate 121 against the aluminum profile 13 according to its structure, further improving the stability of the aluminum profile 13 when it is transported on the conveyor belt 2.

[0061] When multiple second clamps 633 move downward to clamp the aluminum profile 13 on the conveyor belt 2, the unlocking protrusion 16 at the bottom end of the second clamp 633 will press the inclined rotating part 372 in the direction away from the aluminum profile 13, causing the rotating part 372 to rotate in the direction away from the aluminum profile 13, thereby enabling the telescopic plate 121 to disengage from the groove on the side wall of the aluminum profile 13, releasing the limiting and fixing effect on the aluminum profile 13, and allowing the second clamp 633 to clamp the aluminum profile 13 for transportation.

[0062] The working principle of the embodiment of the present application is as follows: when the first clamping jaw 423 clamps the aluminum profile 13 and places it on the connecting frame 36, the aluminum profile 13 presses the two vertical plates 111 downward, so that the vertical plates 111 move the horizontal plates 113 toward the rotating portion 372 during the downward movement, thereby supporting the rotating portion 372, causing the rotating portion 372 to rotate in a direction away from the aluminum profile 13 with the connecting rod as the rotating axis. When the rotating portion 372 rotates in a direction away from the aluminum profile 13 with the connecting rod as the rotating axis, the telescopic plate 121 rotates upward under the elastic force of the rubber spring, gradually rotating into the groove on the side wall of the aluminum profile 13, and then tightening against the groove on the side wall of the aluminum profile 13, so that the aluminum profile 13 can be limited and fixed according to its shape, thereby minimizing the deviation of the aluminum profile 13 when being transported on the conveyor belt 2 and further improving the stability of the aluminum profile 13 when being transported on the conveyor belt 2. When the multiple second clamps 633 move downward to clamp the aluminum profile 13 on the conveyor belt 2, the unlocking protrusion 16 at the bottom end of the downward-moving second clamp 633 can release the limiting and fixing effect of the telescopic plate 121 on the aluminum profile 13, making it convenient to clamp the aluminum profile 13 and transport it.

[0063] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
