When the height of the mounting rack needs to be adjusted, the second locking piece 16 can be loosened, and then the position of the sliding upright post 10 in the groove 901 can be adjusted. In this embodiment, a connecting rod is arranged between the sliding columns 10 on both sides of the support frame 1 for connection.

As shown in fig. 2, the first clamping portion includes a first clamping groove 7 having an opening. In addition, a second clamping portion which is symmetrically arranged with the first clamping portion along the radial direction of the rotating shaft 11 is formed between the upper turnover plate 5 and the lower turnover plate 6, and a second clamping groove 8 with an opening facing the sheet material output end is formed in the second clamping portion. And then in the process of overturning the overturning frame, the first clamping groove 7 and the second clamping groove 8 can respectively overturn the conveyed plate, so that the efficiency of the plate in the conveying and overturning processes is improved.

In this embodiment, the bottom of each of the first clamping groove 7 and the second clamping groove 8 is provided with a blocking plate 17, so as to prevent the plate located in the first clamping groove 7 or the second clamping groove 8 from impacting the upper support rod 13 or the lower support rod 14 during the overturning process of the roll-over stand, thereby affecting the normal use of the device. The blocking plate 17 is specifically a stop block arranged on the opposite side of the upper turnover plate 5 and the lower turnover plate 6, so that the blocking plate 17 can support the plate in the turnover process of the turnover frame. Of course, if the strength of the upper support rod 13 and the lower support rod 14 is sufficient, the blocking plate 17 may not be disposed at the bottom of the first clamping groove 7 or the second clamping groove 8, and the plate may be directly supported by the upper support rod 13 and the lower support rod 14 in the process of turning.

In the embodiment, in order to prevent the sheet material from shaking and damaging the surface of the sheet material during the turning process of the sheet material, the non-slip mat 18 is arranged on the clamping surface of the first clamping groove 7 and the second clamping groove 8. The non-slip mat 18 may be a rubber non-slip mat 18 or the like commonly used in the art.

As shown in fig. 3, in order to conveniently control the conveying of the sheet and the turning of the turning frame, a first sensor 19 and a second sensor 20 for sensing the sheet are disposed on the support frame body 1, and the first sensor 19 and the second sensor 20 are disposed corresponding to the first clamping groove 7 and the second clamping groove 8, respectively. The first inductor 19 is arranged at a position close to the bottom of the first clamping groove 7, and the second inductor 20 is arranged at an opening close to the second clamping groove 8 and facing the sheet material output end. The movement of the conveyor belt 2 and the turning of the turning frame are controlled by the sensing signals of the first sensor 19 and the second sensor 20. The first sensor 19 and the second sensor 20 may be photoelectric sensors commonly used in the prior art.

When the plate feeding device of the embodiment is used, the distance between the upper turnover plate 5 and the lower turnover plate 6 can be adjusted according to the thickness of a plate to be conveyed, the distance between the upper turnover plate 5 and the lower turnover plate 6 is adjusted to a proper position, and then the height of the sliding upright post 10 is adjusted, so that the turnover frame is in a proper height position. After the position is adjusted, the first driving device 3 can be opened, the plate materials are placed on the conveying belt 2, and the plate materials enter the first clamping groove 7 under the conveying of the conveying belt 2.

When the first sensor 19 senses a sheet, the conveyor belt 2 stops moving, the second driving device 4 starts to drive the turnover frame to turn over, the turnover frame turns over for 180 degrees, namely after the positions of the first clamping groove 7 and the second clamping groove 8 are exchanged, the turnover frame stops turning over, and the conveyor belt 2 starts to move. The sheet material in the first clamping groove 7 will leave the first clamping groove 7 under the conveying of the conveyer belt 2, and is conveyed towards the sheet material output end.

And the plate material at the input end of the plate material will enter the second clamping groove 8 under the conveying of the conveying belt 2. After the sheet material is not sensed by the second sensor 20 and the sheet material is sensed by the first sensor 19, the roll-over stand is turned over again by 180 degrees, namely, the first clamping groove 7 and the second clamping groove 8 are both returned to the original positions, and thus, a cycle is completed. When plates with different thicknesses need to be conveyed, the distance between the upper turnover plate 5 and the lower turnover plate 6 is adjusted, and the sliding upright post 10 is adjusted to a proper height. The control of the first driving device 3 and the second driving device 4 can be controlled by a controller commonly used in the prior art, such as a PLC.

According to the plate feeding device, the turnover frame is arranged on the support frame body 1, so that a plate can be turned over in the plate conveying process, the gap between the upper turnover plate 5 and the lower turnover plate 6 can be adjusted, and the plate with different thicknesses can be turned over and conveyed by the height adjusting mechanism.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
