[0022] As shown in Figure 1 , the plate production equipment 100 provided by the embodiments of the present application comprises a plate conveying device A and a plate leveling device B arranged in cooperation with the plate conveying device A, the plate conveying device A is used for conveying the plate, and the plate leveling device B is used for leveling the plate surface of the plate conveyed by the plate conveying device A and righting the vertical surface of the plate. The plate of the embodiments of the present application is a gypsum board C, which is described in detail herein.

[0023] As shown in Figure 1 , Figure 2 , the plate leveling device B comprises a plate leveling device 1 and a plate edge righting device 2 arranged downstream of the plate leveling device 1, the plate leveling device 1 is used for leveling the plate surface of the plate, and the plate edge righting device 2 is used for righting the vertical surface (the side surface of the plate) of the plate and also can be used for leveling the plate surface of the plate. In the initial setting stage, the gypsum board C is subjected to shape leveling and shaping by the plate leveling device B. The plate conveying device A of the embodiments of the present application adopts a belt conveyor, and the gypsum board C is conveyed by the belt conveyor.

[0024] It should be noted that the upstream and downstream described in the embodiments of the present application are defined with respect to the transportation direction of the plate (see Figure 1 the unidirectional arrow for the direction).

[0025] As shown in Figure 1 , the plate leveling device 1 comprises a leveling plate 10 and a pair of pressing blocks 11, the pair of pressing blocks 11 are detachably installed at the two end edges of the upstream side of the leveling plate 10 through connecting members (such as bolts). The leveling plate 10 spans the two sides in the width direction (see Figure 1 the bidirectional arrow for the direction) of the gypsum board C, and levels the plate surface of the gypsum board C in the transportation process of the gypsum board C. Since the water absorption rates of the side edges of the gypsum board C are different, the expansion coefficients are different, and then the two sides are easy to be warped, so the pressing blocks 11 are arranged at the two sides of the upstream side of the leveling plate 10 respectively, and the plate surfaces of the two sides of the gypsum board C are compacted. The pressing blocks 11 can adopt a pressing iron material, and the shape can be a triangular plate, a square plate, etc.

[0026] As shown in Figure 1 , Figure 2 , the plate edge supporting device 2 comprises a support frame 20, a motion tracking plate 21 supported on the support frame 20, and a flexible limiting mechanism 22 provided on the support frame 20.

[0027] The motion tracking plate 21 extends along the width direction of the plate, and is arranged to be placed on the plate surface of the gypsum board C and can follow the motion of the gypsum board C in the width direction of the gypsum board C. The flexible limiting mechanism 22 is installed in cooperation with the motion tracking plate 21, and limits the motion tracking plate 21 in the width direction of the gypsum board C, and makes the motion tracking plate 21 and the gypsum board C have synchronous displacement in the width direction of the plate. The plate edge supporting device 2 further comprises an edge supporter 23 provided on the motion tracking plate 21 and movable with the motion tracking plate 21, and the edge supporter 23 is arranged to support the vertical surface (two side surfaces) of the gypsum board C.

[0028] When the gypsum board C has a certain amount of offset on the plate conveying device A during production, the plate edge supporting device 2 of the embodiment of the application can make the motion tracking plate 21 and the gypsum board C have synchronous displacement in the width direction of the plate through the flexible limiting mechanism 22, so that the edge supporter 23 also has synchronous position with the gypsum board C, thereby avoiding the edge supporter 23 from being fixed while the gypsum board C is displaced in the width direction, causing damage to the gypsum board C.

[0029] The support frame 20 supports both ends of the motion tracking plate 21, and is provided with a pair of grooves (not shown) for mounting both ends of the motion tracking plate 21, which limits the motion of the motion tracking plate 21 in the conveying direction of the gypsum board C, but the motion tracking plate 21 is movable in the width direction of the gypsum board C. The support frame 20 has a frame body of different heights to support the motion tracking plate 21 and the flexible limiting mechanism 22 to the corresponding height.

[0030] As shown in Figure 3 , the flexible limiting mechanism 22 comprises a first side wall 211 located upstream and a second side wall 212 located downstream, and the flexible limiting mechanism 22 abuts against the second side wall 212 to provide a limiting force in the upstream direction.

[0031] As shown in Figure 3 , the flexible limiting mechanism 22 comprises a support seat 220 mounted on the support frame 20, and a ball 221 provided on the support seat 220, and the ball 221 abuts against the second side wall 212 of the motion tracking plate 21. When the gypsum board C is offset in the width direction, the motion tracking plate 21 follows the motion of the gypsum board C, and the ball 221 rolls with the motion tracking plate 21, so that the motion tracking plate 21 has synchronous displacement with the gypsum board C in the width direction of the gypsum board C.

[0032] As shown in Figure 1 , the motion tracking plate 21 is arranged across the width direction of the gypsum board C, and the two ends of the motion tracking plate 21 are respectively supported on the support frame 20. The flexible limiting mechanism 22 includes a plurality of flexible limiting mechanisms 22, which are respectively arranged at the two ends of the motion tracking plate 21.

[0033] As shown in Figure 3 , the motion tracking plate 21 includes a bottom wall 210, a first side wall 211 and a second side wall 212 extending upward from the upstream side and the downstream side of the bottom wall 210, respectively. The flexible limiting mechanism 22 acts on the second side wall 212, and the bottom wall 210 can level the surface of the gypsum board C.

[0034] As shown in Figure 2 , Figure 3 , the edge supporting device 23 includes an adjusting frame 230 and a blocking block 231, and the adjusting frame 230 and the blocking block 231 surround the mounting port 232 to form a hollow mounting port 232. The edge supporting device 23 is sleeved on the motion tracking plate 21 through the mounting port 232. The edge supporting device 23 further includes a locking handle 233 mounted on the adjusting frame 230 and capable of adjusting the height. The locking handle 233 can be inserted into the mounting port 232 and abut against the bottom wall 210 to lock the position of the edge supporting device 23. The thickness of the blocking block 231 is less than the thickness of the gypsum board C.

[0035] The plate edge supporting device 2 of the embodiment of the application can not only provide the mounting of the edge supporting device 23 and the supporting position of the flexible limiting mechanism 22, but also reduce the weight of the motion tracking plate 21, so that the flexible limiting mechanism 22 can keep synchronous motion with the gypsum board C. Moreover, the motion tracking plate 21 is made of aluminum material, so that the motion tracking plate 21 has a lighter mass and can move with the gypsum board C.

[0036] As shown in Figure 2 , the plate edge supporting device 2 further includes a lifting device 24 cooperated with the support frame 20, and the lifting device 24 can drive the plate edge supporting device 2 to move up and down. The lifting device 24 includes two, which are respectively arranged on the racks on both sides of the belt conveyor. The lifting device 24 of the embodiment of the application adopts a pneumatic cylinder, and two pneumatic cylinders are controlled by one air pipe to achieve synchronous lifting. When the two pneumatic cylinders fall, the plate leveling device 1 and the plate edge supporting device 2 fall on the gypsum board C to level and support the edges of the gypsum board C, thereby improving the quality of the gypsum board C.
