[0032] Referring to Figure 1 and Figure 6The down-pressing mechanism comprises a lifting frame 101, a rotating frame 102, a bidirectional screw rod 103, and a down-pressing wheel 104. The lifting frame 101 is fixedly connected to the automatic lifting block 3. The rotating frame 102 is rotatably connected to the left and right ends of the lifting frame 101. The torsion spring 1 is fixedly connected between the rotating frame 102 and the lifting frame 101. The bidirectional screw rod 103 is connected to the lower part of the rotating frame 102. The down-pressing wheel 104 is threadedly connected to the front and rear ends of the bidirectional screw rod 103. The torsion spring 2 is fixedly connected between the down-pressing wheel 104 and the bidirectional screw rod 103.

[0033] Firstly, the door frame is placed on the top of the workbench 1 and is coated with glue. The electric sliding block 6 is controlled to move in the left-right direction, thereby driving the two automatic longitudinal cutters 7 to move in the left-right direction, so that the positions of the automatic longitudinal cutters 7 adapt to the length of the door frame. The position of the automatic transverse cutter 9 in the front-rear direction can be adjusted by loosening the bolt, and the position of the automatic transverse cutter 9 is adapted to the width of the door frame by tightening the bolt. Then, the fireproof material to be cut is placed on the two automatic transverse cutters 9. The automatic lifting block 3 is controlled to descend, thereby driving the connecting box 4, the knocking disc 5, the lifting frame 101, the rotating frame 102, the bidirectional screw rod 103, and the down-pressing wheel 104 to descend. When the down-pressing wheel 104 contacts the fireproof material, the down-pressing wheel 104 stops descending relative to the fireproof material, while the automatic lifting block 3, the connecting box 4, the knocking disc 5, the lifting frame 101, and the rotating frame 102 continue to descend, so that the rotating frame 102 rotates, the torsion spring 1 deforms, thereby driving the two bidirectional screw rods 103 to move away from each other, and the down-pressing wheel 104 rolls on the surface of the fireproof material. Since the down-pressing wheel 104 and the bidirectional screw rod 103 are threadedly connected, the two down-pressing wheels 104 on the same bidirectional screw rod 103 move away from each other in the front-rear direction at the same time, the torsion spring 2 deforms, and the down-pressing wheel 104 presses the fireproof material. The fireproof material is sawn off by controlling the two automatic transverse cutters 9 to move reciprocally in the left-right direction and the two automatic longitudinal cutters 7 to move reciprocally in the front-rear direction, so that the fireproof material is cut. Thus, the fireproof material is automatically cut according to the specifications of the door frame, and the cut fireproof material is pressed into the door frame. Then, the servo motor is controlled to drive the electric rotating shaft 51 to rotate, the eccentric shaft block 513 and the eccentric shaft block 514 rotate around the output shaft of the servo motor, and the eccentric shaft block 513 and the eccentric shaft block 514 move reciprocally upward and downward in sequence, so that the knocking disc 5 is pulled to move reciprocally upward and downward by the transmission rod 52. The reset spring deforms adaptively, the knocking disc 5 knocks the fireproof material, and the fireproof material is completely embedded into the door frame. Then, the automatic lifting block 3 is controlled to ascend, thereby driving the connecting box 4, the knocking disc 5, the lifting frame 101, the rotating frame 102, the bidirectional screw rod 103, and the down-pressing wheel 104 to ascend and reset, so that the filling work of the fireproof material for the door frame is completed, the fireproof material is automatically cut and knocked, and the work efficiency is high.
