[0088] Step 2, assembling the pallet mold; the mold after the fabric is transported by the first conveying member 110 to the mold intercepting unit 200, and the intercepting member 220 abuts against the first conveying member 110 for interception. At the same time, the pallet stack is placed on the second pallet support seat for stacking and conveying. The pallet conveying member 360 drives the second pallet support member 370 to approach the first pallet support member 320, so that the pallet stack is supported by the first pallet support member 320 and the second pallet support member 370 at the same time.

When the pallet is located directly below the first conveying member 110, the interception driving member 210 drives the interception member 220 to move upward in the vertical direction to be spaced from the first conveying member 110. When the mold runs with the first conveying member 110 to the side where the interception member 220 is close to the second conveying member 310, the interception driving member 210 drives the interception member 220 to move downward in the vertical direction to abut against the first conveying member 110.

[0090] Step 4, separation of pallet and mold; after the curing is completed, the preform, mold and pallet are transported to the third conveyor 510 by the transfer vehicle 410, the baffle 511 of the third conveyor 510 separates the pallet in the third conveyor 510, and the push plate of the second push assembly 530 reciprocates along the extension direction of the fourth conveyor 520 through the driving action of the second push driving member to push the mold from the third conveyor 510 to the fourth conveyor 520;

[0091] Step 5, demoulding; the mold is transported to the demoulding unit 600 by the fourth conveying member 520 and is located in the first channel. The edge of the mold is lifted up by the top roller of the first pressing plate 610 or the second pressing plate 620 to separate the mold from the preform. When the mold enters between the first pressing plate 610 and the second pressing plate 620, the mold opening faces upward, the top roller group 630 is located above the mold and abuts against the edge of the mold, and the rope collecting device 640 is driven to perform the rope collecting operation. The rope collecting action of the rope collecting device 640 drives the connecting member to move, and the displacement of the connecting member drives the connected connecting ring 650 along its axial direction. The first pressing plate 610 and the second pressing plate 620 are rotated to flip over. During the flipping process, the vibrating element continuously acts to assist the mold and the precast concrete part to be separated. After the flipping is completed, the mold opening faces downward. The top roller group 630 is located below the mold and abuts against the edge of the mold to lift the mold. The first pressing plate 610 and the second pressing plate 620 are provided with a conveying roller and a conveying roller driving motor for driving the conveying roller to rotate. The conveying roller driving motor drives the conveying roller to rotate, so as to drive the mold and the precast concrete part located between the second pressing plate 620 and the first pressing plate 610 to move, and the removal device is removed to realize demoulding;

[0092] Step 6: Recycling of prefabricated panels: The prefabricated panels are transported by the fifth conveyor 710 to a prefabricated panel recycling box for bundling and recycling.

4. The production system for preparing prefabricated panels according to any one of claims 1 to 3, characterized in that: In the demoulding unit, the first pressing plate and / or the second pressing plate is connected to a vibrating member.

5. The production system for preparing prefabricated panels according to claim 1, characterized in that: The mold intercepting unit also includes a mold pushing assembly located above the first conveying member, the mold pushing assembly includes a pushing driving member and a pushing plate connected to the pushing driving member, the pushing driving member drives the pushing plate to reciprocate along the extension direction of the first conveying member to push the mold from the first conveying member to the second conveying member.

6. The production system for preparing prefabricated panels according to claim 1, characterized in that: The mold intercepting unit further includes a supporting bracket, which includes a rack arranged along a direction perpendicular to the extension direction of the first conveying member. The intercepting member is hinged with a gear, and the gear is meshed with the rack.

7. The production system for preparing prefabricated panels according to claim 1, characterized in that: The pallet conveying unit further includes a pallet conveying member, and the pallet conveying member is provided with a second pallet supporting seat fixedly connected thereto.

8. The production system for preparing prefabricated panels according to claim 1, characterized in that: The pallet conveying unit further includes an abutment plate and a lifting device, wherein the abutment plate is spaced apart from the first pallet support seat in the vertical direction, and the lifting device is connected to the first pallet support seat to drive the first pallet support seat to reciprocate in the vertical direction.

9. A method for preparing a prefabricated board, using the system for preparing a prefabricated board as claimed in claims 1 to 8, characterized in that: The following steps are involved: Step 1: Fabric; Add concrete to the concrete placing machine, which puts the internal concrete into the mold according to the specifications of the mold, and at the same time puts in pipe fittings to prepare the prestressed reserved holes; Step 2, assembling the pallet mold; the mold after the cloth is transported by the first conveying member to the mold intercepting unit, and the intercepting member abuts against the first conveying member for interception. At the same time, the first pushing component of the pallet conveying unit pushes the pallet located on the first pallet supporting member to move to the starting end of the second conveying member along the running direction, and the pallet is conveyed by the second conveying member. When the pallet is located directly below the first conveying member, the intercepting driving member drives the intercepting member to reciprocate in the vertical direction to be separated from the first conveying member, and the mold is conveyed to the top of the pallet located on the second conveying member; Step 3: Curing: The pallet and the mold above it are transferred to the curing kiln for curing by a transfer vehicle; Step 4, separation of pallet and mold; after curing, the prefabricated parts, molds and pallets are transported to the third conveyor by the transfer vehicle, the baffle of the third conveyor separates the pallet in the third conveyor, and the second pushing assembly pushes the mold from the third conveyor to the fourth conveyor; Step 5, demoulding; the mold is transported to the demoulding unit by the fourth conveyor, located in the first channel, and the edge of the mold is lifted up by the top roller of the first pressing plate or the second pressing plate to separate the mold and the preform; Step 6, prefabricated board recycling: the prefabricated boards are transported to the prefabricated board recycling box by the fifth conveyor for bundling and recycling.
