When the invention works: the driving part 1 is used for realizing the action of lifting the gypsum board forming plate, and simultaneously, the action rod is pulled to ensure that the chamfered block 3 is separated from the contact with the side edge of the gypsum board (namely, in the initial state, the chamfered block 3 is contacted with the side edge of the gypsum board and matched with the gypsum board trimming device to carry out vertical edge operation on the side edge of the gypsum board) until the driving part 1 completely lifts the gypsum board forming plate, in the process, the chamfered block 3 is contacted with the limiting mechanism 4, and through the limiting mechanism 4, when the driving part 1 descends to ensure that the gypsum board forming plate is recovered, the action rod 2 moves towards the side edge of the gypsum board under the self elastic action, and because of the blockage of the limiting mechanism 4, the action rod 2 is limited by the limiting mechanism 4 and can not be contacted with the side edge of the gypsum board, when an operator manually operates the limiting mechanism 4, the limiting mechanism 4 releases the chamfered block 3, so that the chamfered dice 3 come into contact with the side edges of the plasterboard. That is to say, the device has no action when artificially lifting 1 to clean the slag and has no influence on the vertical edge of the gypsum board.
Further, the adjusting mechanism 24 is used for adjusting the distance between the edge chamfering block 3 of the action rod 2 under the self elastic action (i.e. the action rod 2 has the tendency of pushing the edge chamfering block 3 to the side edge of the gypsum board without being under the action of the traction force of the driving piece 1), and the distance between the edge chamfering block 3 of the action rod 2 under the self elastic action and the side edge of the gypsum board is adjusted through the adjusting mechanism 24 when the limiting mechanism 4 is manually operated by an operator to release the edge chamfering block 3 by the limiting mechanism 4, and the driving piece 1 does not lift the gypsum board forming board and has the traction action on the action rod 2.

The threaded rod 22 passes axially through the nacelle 21 and the part of the mast connected to the cable 102 forms a traction mast (the part to the left in fig. 1 and 2), on which the adjusting mechanism 24 is mounted.
Wherein the adjustment mechanism 24 comprises a nut threadedly connected to the drawbar body.
The limiting mechanism 4 is fixedly installed on the cabin 21, the limiting mechanism 4 comprises a bracket 41 installed on the surface of the cabin 21 along the length direction of the cabin 21, and a stop block 42 vertical to the bracket 41 is arranged at the tail end of the bracket 41 extending out of the end part of the cabin 21;

Further, in order to match the action of the forming plate cylinder 101 and maintain the stability of the threaded rod 22 in the adjusting process, a first end cover 25 is arranged at the end part of the cabin body 21 close to the forming plate support 103, a second end cover 26 is arranged at the end part of the cabin body 21 close to the gypsum board, shaft holes for the threaded rod 22 to axially pass through are formed in the first end cover 25 and the second end cover 25, the shaft hole in the first end cover 25 is larger than the shaft hole in the second end cover 26, the hole between the shaft hole in the second end cover 26 and the threaded rod 22 is 1 mm-2 mm, a buffer cavity 27 is formed inside the cabin body 21, a piston ring 28 is arranged on the shaft body of the threaded rod 22 in the buffer cavity 27, the circumferential surface of the piston ring 28 is attached to the inner wall of the cabin body 21, and a spring 23 is sleeved on the shaft body of the threaded rod 22 between the piston ring 28 and the first end cover 25.
Further, in order to realize that the adjusting mechanism 24 completes the automatic release of the chamfering block 3 when the forming cylinder 101 loses the traction action on the threaded rod 22, the invention has specific preconditions in the process that the forming plate cylinder 101 needs to lift and lower the gypsum board forming plate: the forming plate cylinder 101 is at the uniform velocity lifting when lifting the gypsum board forming plate, and when descending the gypsum board forming plate, then at the uniform velocity in-process with the contact of gypsum board forming plate, when the gypsum board forming plate was descended to the spacing support (the structure of the assembly line in the current gypsum board production process) contact with the gypsum board forming plate, then forming plate cylinder 101 resumes to initial position (its purpose is to accomplish and loses traction force to wire rope 102 in the twinkling of an eye), that is to say at the in-process that forming plate cylinder 101 descends and contacts with the gypsum board forming plate, forming plate cylinder 101 still possesses the traction force effect to threaded rod 22.
Under the above premise, the stopper 42 of the present invention is installed on the bracket 41 through the guide hole 45, the guide hole 45 includes the upper cavity 451 and the lower cavity 452, the gap between the lower cavity 452 and the stopper 42 is less than 0.1mm, the gap between the upper cavity 451 and the stopper 42 is between 4mm and 5mm, and the top of the stopper 42 is provided with the sealing edge 46 matching with the upper cavity 451.
