[0036] The screw rod sliding mechanism includes a sliding motor 441, a screw rod 442 and a guide rail 443. The sliding motor 441 and the guide rail 443 are arranged on the second frame 41. The screw rod 442 is connected to the output shaft of the sliding motor 441. The external thread of the screw rod 442 is matched and connected with the internal thread of the second base 431. The second base 431 is connected to the guide rail 443 through a slider. The axis of the guide rail 443 is parallel to the axis of the screw rod 4442.

The lifting roller conveying mechanism 12 is lowered, and the wooden door falls on the first workbench 13 of the third processing station 7. The first lifting pressing mechanism presses down to stably fix the wooden door. The bottom surface positioning mechanism is used to control the position of the bottom surface of the wooden door at the first workbench 13 of the third processing station 7 when the bottom surface of the wooden door is processed, so as to ensure the stability of the processing. The top surface positioning mechanism is arranged at one end of the first processing station 1 close to the bottom surface processing mechanism 8. The structure of the top surface positioning mechanism is similar to that of the bottom surface positioning mechanism, but the lifting roller conveying mechanism 12 does not need to be reversed when in use. It only requires the top end of the wooden door to rest against the top surface positioning mechanism and the lower pressing mechanism to press down to position the top end of the wooden door on the left side processing mechanism to process the top end of the wooden door.
