[0020] like Figures 1 to 5 As shown, a device for stably and quickly rolling a steel plate comprises a pressing roller 3 sliding in a plate rolling machine body 1, and rotating side rollers 4 are arranged on both sides of the pressing roller 3. Positioning devices 2 are fixedly arranged on both sides of the plate rolling machine body 1, and a sliding frame 202 is arranged in a fixed frame 201 in the positioning device 2. A rotating roller 206 is arranged at the end of the sliding frame 202, and the roller 206 abuts against both sides of the steel plate, and the roller 206 covers the initial position and the rolling forming position of the steel plate. According to this structure, the positioning device 2 is installed around the plate rolling machine body 1. After the steel plate enters the plate rolling machine body 1, the driving sliding frame 202 drives the roller 206 to abut against both sides of the steel plate, thereby positioning the steel plate. The length of the roller 206 covers the initial position and the rolling forming position of the steel plate, and can fix the steel plate during the whole rolling process.
