Plate processing device for building engineering construction

The plate processing device for building engineering construction comprises supporting columns, a first guide rail and a second guide rail, the first guide rail is fixedly connected to the upper ends of the two supporting columns at the front end, and the second guide rail is fixedly connected to the upper ends of the two supporting columns at the rear end. When the plate processing device for building engineering construction is used, a motor connected with a round rod is started, an output shaft of the motor rotates to drive the round rod to rotate, so that a belt roller on the outer side rotates, a belt on the outer side is driven to rotate to drive all the belt rollers to rotate together, and the round rod rotates together to drive a driving roller on the outer side to rotate at the same time; the lowest plate at the left side of the upper end of the device passes through the space between the baffle plate and the driving roller along with the driving roller, and then moves to the right end until the lowe
