Referring to fig. 7, in some embodiments, in order to enable the pressing seat 525 to be in stable contact with the plate in the process of lowering and avoid hard contact with the plate, a mounting groove 526 is formed in the bottom of the pressing seat 525, a pressing sheet 527 is arranged in the mounting groove 526, the pressing sheet 527 movably passes through the mounting groove 526 through a guide pillar 528, one end of the pressing sheet 527, which passes through the mounting groove 526, is locked through a nut, a damping spring 529 is sleeved in a region between the pressing sheet 527 and the bottom of the mounting groove 526, and two ends of the damping spring 529 are respectively abutted against the pressing sheet 527 and the bottom of the mounting groove 526; the pressing piece 527 is provided with a hook 522 at an end far away from the pinch conveying line 110. The design of the pressing piece 527 can keep the pressing piece always abutting against the surface of the plate, so that the plate is prevented from jumping excessively in the movement process in order to increase the contact stability of the pressing piece. When the guide post 528 is movably inserted into the pressing seat 525, the inserted hole is slightly larger than the outer diameter of the guide post 528, so that the whole pressing piece 527 has a certain movable space swinging along the axial direction of the guide post 528. In addition, the design of the hook 522 can be convenient for the hook to be abutted with the end surface of the plate, so that the pushing stability is improved.
Further fig. 1 to 3, in one embodiment of the present application, in order to implement the reciprocating motion of the pressing mechanism 520 to continuously push the plate material to feed forward, the traveling mechanism 510 includes a rail 511, a sliding platform 512, and a traveling motor 513 disposed on the sliding platform 512, the rail 511 is disposed on the frame 100, the sliding platform 512 is slidably mounted on the rail 511, a rack 120 disposed parallel to the rail 511 is disposed on the frame 100, and an output end of the traveling motor 513 is meshed with the rack 120 through a gear, and the traveling motor 513 is electrically connected with a control system. The sliding platform 512 may also be driven by a motor screw rod to realize conveying, which is selected according to practical use requirements. The use of the cooperation of the gear and rack 120 in this embodiment can effectively increase the conveying force thereof.
Referring to fig. 2 again, it should be noted that, in the present application, since the first pushing device 500 needs to pass through the conveying device 400 downwards and hook the uppermost sheet of the first stacking frame 210 in the use process, and the second pushing device 600 only needs to push the uppermost sheet of the second stacking frame 310 reciprocally, the second pushing device 600 in the present application may adopt the above-mentioned travelling mechanism 510 and the pressing seat 525 to cooperate, that is, the pressing seat 525 is directly installed on the travelling mechanism 510, the overall structure is simplified, and meanwhile, the working requirement is also satisfied.
The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
