The second power unit 330 includes a rack 331 screw-mounted on a longitudinal beam of the second frame 310, a horizontal synchronizing shaft 332, a vertical synchronizing shaft 333, a gear unit, and a motor (not shown in the drawing) driving the horizontal synchronizing shaft 332. Specifically, the horizontal synchronizing shafts 332 are disposed on two transverse beams of the second frame 310 up and down, and the racks 331 are disposed on four longitudinal beams of the second frame 310; two driving gears 335 are keyed on both sides of the horizontal synchronizing shaft 332 of the upper transverse beam, and are respectively engaged with two racks 331 of the upper longitudinal beam; two driven gears 336 are key-mounted on both sides of the horizontal synchronizing shaft 332 of the transverse beam at the lower portion to be respectively engaged with the two racks 331 of the longitudinal beam at the lower portion.

In some preferred embodiments, the multi-layer feeding mechanism 300 further includes a kick-out unit 350 provided on a rear end face (blanking end) of the frame portion of the conveying platform 321, which is adapted to push the work piece on the platen of the press system, which has been subjected to the hot pressing, toward the blanking system while the multi-layer feeding mechanism 300 feeds the press system. The kick-out unit 350 includes a pair of side end plates 351 formed to extend from both side plates of the frame portion of the transfer stage 321 toward one side of the press system, a link 352 screw-mounted through the pair of side end plates 351, and a kick-out block 353 fitted over the link 352. In order to make the installation of the poking block 353 more stable, a pair of connecting rods 352 are arranged on the pair of side end plates 351, and the poking block 353 is sleeved on the pair of connecting rods 352, so that the poking block 353 can be prevented from overturning or rotating.

The side of the poking block 353 facing the press system comprises, from top to bottom, a wedge-shaped surface, a first protrusion, a concave arc surface, a second protrusion. The setting of wedge face and concave cambered surface can make the material piece 353 dodge the wainscot material beyond the substrate breadth outward, and wainscot material after the hot pressing often is fragile and lacks the intensity of supporting propelling movement. And according to the difference of the thicknesses of the workpieces, the wedge-shaped surface or the concave cambered surface is avoided.

subsequently, the assembly operating mechanism 100 starts the transfer to transfer the assembled workpiece to the lifting and conveying mechanism 200, and of course, the operator can control the start and stop of the assembly operating mechanism 100 by independently controlling the switch of the assembly operating mechanism 100, or can stop the transfer of the assembly operating mechanism 100 at equal time intervals in the control system so that the operator can perform assembly or start the transfer to transfer the assembled workpiece to the conveying platform 220 of the lifting and conveying mechanism 200;

then, the first power unit 240 of the lifting and conveying mechanism 200 is started so that the conveying platform 220 rises to a certain height, the height is determined by the group 1 positioning sensor and is equal to the height of a certain conveying platform 321 of the multi-layer feeding mechanism 300 to be fed, in general, the conveying platforms 321 of the multi-layer conveying unit 320 are fed layer by layer from bottom to top, and naturally, the conveying platform 220 can be stopped at a certain position with the same height of a certain conveying platform 321 as required;

then, the conveying platform 220 starts conveying to convey the assembled workpiece to the corresponding conveying platform 321, and then the first power unit 240 starts to reset the conveying platform 220 to the same height as the operating platform of the assembled operating mechanism 100; repeating the above actions until all or a designated conveying platform 321 is provided with assembled workpieces;

finally, the second power unit 330 starts to drive the multi-layered conveying unit 320 to move toward the press system side through the rack-and-pinion system, in the movement close to the press system, the front end of the multi-layered conveying unit 320 enters the platen of the press system and walks thereon, the kick-out block 353 pushes the workpiece toward the blanking system side, at the same time, the conveying platform 321 starts to convey toward the press system side and the multi-layered conveying unit 320 continues to move toward the press system side when the fourth positioning sensor 424 of the 2 nd group positioning sensor detects the rear end (e.g., the position of the multi-layered unit vertical beam 322 is a judgment position), the conveying platform 321 continues to drive and the second power unit 330 starts to slow down when the fifth positioning sensor 425 detects the rear end, the conveying platform 321 continues to drive and the second power unit 330 starts to stop when the sixth positioning sensor 426 detects the rear end; after a set time interval, for example, 2-3 seconds, or without a pause, the second power unit 330 starts to retreat (move away from the press system), at which time the conveying platform 321 continues to drive so that the assembled workpiece falls on the press plate and the conveying platform 321 can retreat smoothly, the conveying platform 321 stops driving when the third positioning sensor 423 detects the rear end and the second power unit 330 continues to move toward the side of the elevating transmission mechanism 200, the second power unit 330 starts to decelerate when the second positioning sensor 422 detects the rear end, and the second power unit 330 stops when the first positioning sensor 421 detects the rear end.

Preferably, the lower deck 521 is inclined downward at an angle of 3 to 5 °. The lifting receiving mechanism 600 comprises a fourth frame 610, a third power unit 620, a discharging conveying platform 630 and a third guiding unit 640. The fourth frame 610 is a prior art frame structure adapted to provide mounting support and space for other components of the lift and lower receiving mechanism 600. The third power unit 620, the discharging and conveying platform 630, and the third guide unit 640 may have the same structure and operation as the first power unit 220, the conveying platform 230, and the first guide unit 240, respectively.

However, in other embodiments, the blanking transfer platform 630 is configured differently from the transfer platform 230 in that it includes a frame platform 631, a pair of independently driven transfer belts 632 mounted by the frame platform 631, the pair of transfer belts 632 being adapted to clear the structure of the blanking laminate 521. Meanwhile, the elevation receiving mechanism 600 further includes a finishing unit 650 mounted on the frame platform 631. The finishing unit 650 includes a limit guard 651 at the conveying end of the pair of conveying belts 632 and side finishing members at both sides of the rear end of the pair of conveying belts 632. The side finishing assembly comprises a side finishing push plate 652, a guide block 653 fixedly connected to the bottom of the side finishing push plate 652, a guide rail 654 matched with the guide block 653, and air cylinders (not shown in the figure) connected with the side surfaces of the guide block 653, wherein the two groups of air cylinders are suitable for enabling the two groups of side finishing push plates 652 to be close to or far away from each other.

The automated stacking mechanism 700 may be of the prior art, for example, comprising a gantry beam 710, a vacuum chuck set 720, a lift head 730 capable of driving the vacuum chuck set 720 up and down, and a travel head 740 capable of driving the lift head 730 to travel along the gantry beam 710.

The working mode of the feeding system of the embodiment of the application is as follows:

firstly, after the workpiece is pushed to one side of a blanking system by the poking block 353, the workpiece falls on the blanking laminate 521, and the workpiece slides to one side of the limit baffle 523 until being blocked by the limit baffle 523 due to the inclined structure of the blanking laminate 521 and the arrangement of the row wheel 522;

subsequently, after the third power unit 620 drives the discharging conveyor platform 630 to rise to a level flush with the lowermost discharging deck 521, the conveyor belt 632 is driven to convey the craftsman to the end of the conveyor belt 632 until being blocked by the rear fiber baffle 651, at which time the pair of side finishing pushplates 652 are brought close to center the work piece;

finally, the vacuum chuck assembly 720 takes away the workpiece and automatically stacks at the set position, and at the same time, the blanking conveying platform 630 ascends layer by layer, and the workpiece on the corresponding blanking laminate 521 is taken out until the blanking is completed, and the blanking is lowered and reset.
