[0029] Example 1

[0030] like Figure 1-6 As shown, this embodiment provides a concrete precast part pallet separation device, including a frame 1, a transmission mechanism and a separation mechanism, the transmission mechanism including a first transmission assembly 2 and a second transmission assembly 3 installed on the frame 1, the height of the first transmission assembly 2 is greater than the height of the second transmission assembly 3, the separation mechanism includes a support frame 14 and a separation assembly, the separation assembly is slidably installed on the support frame 14 and is located above the first transmission assembly 2.

[0031] The first transmission assembly 2 transports the mold with the pallet to the separation station. The separation assembly then separates the mold from the pallet and transports it to the next processing station. The first transmission assembly 2 continues to transport the pallet, allowing it to enter the second transmission assembly 3, which simultaneously transports the next mold with the pallet to the separation station for separation. The second transmission assembly 3 then transports the pallet to the collection station 12 for collection. The entire process utilizes mechanical equipment to process the pallet and mold, resulting in a high degree of mechanization, effectively reducing labor intensity and increasing the speed of pallet and mold separation. Furthermore, the separation operation and pallet transport can be independent, making it easy to operate.

[0032] In this embodiment, the first transmission assembly 2 and the second transmission assembly 3 have the same structure, each comprising a transmission motor 4, a conveyor chain 6, a first conveyor gear, a second conveyor gear, and a rotating shaft 5. The rotating shaft 5 is rotatably mounted on the frame 1. The first conveyor gear is provided at each end of the rotating shaft 5. The second conveyor gear is mounted on the frame 1. A main gear is mounted on the output end of the transmission motor 4. The conveyor chain 6 is wound around the main gear, the first conveyor gear, and the second conveyor gear. During use, the transmission motor 4 is started, which drives the second conveyor gear to rotate. The second conveyor gear drives the conveyor chain 6 to rotate. The rotation of the conveyor chain 6 causes the first conveyor gear to rotate, thereby achieving material conveyance.

[0033] In this embodiment, the separation assembly includes a rack 8, a transmission gear 9, a sliding block 7, and a pusher. The sliding block 7 is slidably mounted on the support frame 14. The racks 8 are mounted on both sides of the support frame 14. The racks 8 are meshed with the transmission gears 9. The transmission gears 9 are connected to a driving member 10. The pushing member is movably mounted on the support frame 14. The driving member 10 provides power to the transmission gear 9, causing the transmission gear 9 to rotate, thereby moving the transmission gear 9 along the length of the rack 8, thereby driving the sliding block 7 to move on the support frame 14, allowing the pushing member to push the mold away from the pallet, thereby separating the pallet from the mold. The driving member 10 can be a hydraulic motor.

[0034] In this embodiment, a first air cylinder 19 is mounted on the sliding block 7, and a driving end of the first air cylinder 19 is connected to the pusher. The first air cylinder 19 can be used to adjust the height of the pusher so that the pusher can just push the mold without causing the pallet to move, thereby improving the accuracy of the separation between the pallet and the mold.

[0035] In this embodiment, the sliding block 7 is mounted with opposing fixed plates 15, each of which is equipped with at least one set of limiting rollers 16. The pusher includes two vertical rods 17, which are connected by a crossbeam 18. The driving end of a first cylinder 19 is connected to the bottom of the crossbeam 18, with one vertical rod 17 positioned between the two limiting rollers 16 of one fixed plate 15, and the other vertical rod 17 positioned between the two limiting rollers 16 of the other fixed plate 15. Slots 22 are defined on both sides of the vertical rods 17, within which the limiting rollers 16 are mounted. A guide rod 21 is connected to the bottom of each vertical rod 17, and a push plate 20 is connected to the end of each guide rod 21 away from the vertical rod 17. The first cylinder 19 extends and retracts, driving the crossbeam 18 up and down. The crossbeam 18 then drives the vertical rods 17 up and down, causing the guide rods 21 and the push plate 20 to move up and down, thereby adjusting the height of the push plate 20. The limiting roller 16 is used to limit the vertical rod 17 so that the vertical rod 17 can move in the vertical direction, thereby improving the stability of the movement of the vertical rod 17 and preventing the vertical rod 17 from deflecting.

[0036] In this embodiment, baffles 13 are provided on both sides of the frame 1, and connecting rods are provided between the baffles 13 and the frame 1. During the transportation of the mold with the pallet, the baffles 13 can prevent the mold from falling from the pallet, thereby improving the safety of transportation.

[0037] In this embodiment, the separation device further includes a collection mechanism, which includes a pallet placement platform 23 mounted in the transmission direction of the second transmission assembly 3, slide rails 24 provided on both sides of the pallet placement platform 23, and a clamping assembly slidably mounted on the slide rails 24. When the second transmission assembly 3 transports the pallet to the collection station 12, the clamping assembly is used to clamp the pallet away from the collection station 12 and place it on the pallet placement platform 23. This operation is repeated to stack the pallets layer by layer.

[0038] In this embodiment, the clamping assembly includes a mounting frame 25, a lifting motor 27, a lifting plate 26, a second cylinder 30, and a clamping claw installed on the mounting frame 25. The mounting frame 25 is slidably mounted on the slide rail 24. The lifting motor 27 and the lifting plate 26 are connected to each other via a transmission member, and the driving end of the second cylinder 30 is connected to the clamping claw. After the clamping assembly slides on the slide rail 24 to the collection station 12, the lifting motor 27 controls the lifting plate 26 to rise and fall, and the second cylinder 30 controls the clamping claw to clamp the pallet. The clamping assembly is then controlled to move so that the pallet is directly above the pallet placement platform 23. The lifting motor 27 controls the lifting plate 26 to descend so that the pallet just contacts the pallet placement platform 23. The second cylinder 30 is activated to release the clamping claw and place the pallet on the pallet placement platform 23. This cycle is repeated to achieve stacking and storage of multiple pallets. Preferably, the clamping claw includes a first clamping portion 28 and a second clamping portion 29, and the first clamping portion 28 and the second clamping portion 29 are both connected to a second cylinder 30. By controlling the second cylinder 30, the first clamping portion 28 and the second clamping portion 29 are moved closer to or away from each other, thereby achieving clamping or release of the pallet.

[0039] In the embodiment of the present invention, a mold placement table 11 is provided in the movement direction of the separation mechanism. After the push plate pushes the mold away from the pallet, the pallet is pushed to the mold placement table 11 to place the mold so as to facilitate the next processing operation on the mold.

[0040] The working principle of a concrete precast part pallet separation device is as follows: a mold with a pallet is placed on the first transmission assembly 2, the transmission motor 4 of the first transmission assembly 2 is started, the transmission motor 4 drives the second transmission gear to rotate, the second transmission gear drives the transmission chain 6 to rotate, the rotation of the transmission chain 6 causes the first transmission gear to rotate, and the mold with the pallet is transported to the separation station, and the transmission motor 4 of the first transmission assembly 2 is turned off.

[0041] The first cylinder 19 is activated, driving the crossbeam 18 downward, which in turn drives the vertical rod 17 downward, causing the guide rod 21 and push plate 20 to move downward until the push plate 20 is level with the mold. The drive member 10 provides power to the transmission gear 9, causing it to rotate and move along the length of the rack 8, thereby driving the sliding block 7 on the support frame 14, allowing the push plate 20 to push the mold off the pallet until the mold is transported to the mold placement table 11, separating the pallet from the mold.

[0042] Start the transmission motor 4 of the first transmission assembly 2 and the second transmission assembly 3, and let the first transmission assembly 2 continue to transport the pallet to allow it to enter the second transmission assembly 3. The second transmission assembly 3 transports the pallet to the collection station 12. Let the clamping assembly slide on the slide rail 24 to the collection station 12, start the lifting motor 27, and the lifting motor 27 controls the lifting plate 26 to descend until the pallet is located between the clamping claws. Start the second cylinder 30, and the second cylinder 30 drives the clamping claws to move toward the pallet to clamp and secure the pallet. Then control the movement of the clamping assembly so that the pallet is directly above the pallet placement table 23. The lifting motor 27 controls the lifting plate 26 to descend so that the pallet just contacts the pallet placement table 23. Start the second cylinder 30, release the clamping claws, and place the pallet on the pallet placement table 23. Repeat this cycle to achieve stacking and storage of multiple pallets.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
