[0044] Embodiment 4

[0045] The head position detection module of the table board and the tail position detection module of the table board are both table board position sensors for collecting the edge position of the wooden table board 1. The table board position sensors are respectively installed on the first cutter mounting frame 413 and the second cutter mounting frame 423 and correspond to the roller conveying line 3.

[0046] Embodiment 5

[0047] The table board head cutting unit 41 and the table board tail cutting unit 42 are respectively provided with a first limiting chain 417 and a second limiting chain 427. One end of the first limiting chain 417 is connected with the cutting mechanism mounting frame 43, the other end is connected with the first sliding block 412, and the first sliding block 412 is limited. One end of the second limiting chain 427 is connected with the cutting mechanism mounting frame 43, the other end is connected with the second sliding block 422, and the second sliding block 422 is limited.

[0048] When the baffle is used as the position sensor, the working principle of the automatic cutting device in the embodiment is as follows:

[0049] Firstly, the industrial computer controls the head position detection baffle rotating drive motor of the table board to drive the head position detection baffle 416 to the bottom limit position, and the tail position detection baffle reset torsion spring at the tail position detection baffle 426 is in a compressed state.

[0050] When the wooden table board 1 moves to the head position detection baffle 416 of the table board, the head position detection baffle 416 is driven to slide together, the second electric cylinder drives the first driving motor 414 and the first cutter 415 to move to the head position detection baffle 416, and directly cuts off the excess edge strip of the head of the table board. Then, after the first driving motor 414 drives the head position detection baffle reset torsion spring to be in a compressed state, the first electric cylinder 411 drives the first sliding block 412 to reset.

[0051] After the first electric cylinder 411 drives the first slider 412 to reset, the tail position detection baffle 426 of the table board has overlapped the wooden table board 1. When the proximity sensor detects that the wooden table board leaves, the tail position detection baffle 426 falls down. Then the third electric cylinder 421 drives the second slider 422 to move at a speed slightly greater than the conveying speed of the roller conveying line 3. The speed difference is very small but can ensure that the tail position detection baffle 426 of the table board closely adheres to the second slider 422. Then the fourth electric cylinder drives the second driving motor 424 and the second cutter 425 to move towards the tail position detection baffle 426 of the table board, directly cutting off the excess edge strip at the tail of the table board. Then the tail position detection baffle 426 of the table board resets.

[0052] After the cutting off is completed in sequence, the industrial computer controls the rotation driving motor of the head position detection baffle of the table board to drive the head position detection baffle of the table board to the bottom limit position, waiting for the arrival of the next wooden table board.

[0053] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
