the track is divided into a feeding track 701 and a rolling track 702, and two ends of the feeding track 701 and the rolling track 702 are connected through an arc track, so that the rollers 801 form loop motion inside the feeding track 701 and the rolling track 702;
when the roller 801 moves under the action of the power assembly 6 and is located in the pushing area 7011 in the feeding track 701, at this time, the limiting blocks 803 at two ends of the roller 801 are attached to the limiting plates 703 on the track, the length of the limiting plates 703 is the same as that of the pushing area 7011, so that when the roller 801 is located in the feeding track 701 and moves under the action of the power assembly 6, the rollers 801 on two sides of the steel plate drive the steel plate to horizontally slide in the main body 9 through static friction, the limiting blocks 803 synchronously leave the limiting plates 703 on the track after the roller 801 leaves the pushing area 7011, the roller 801 enters the pre-rolling area 7012 after leaving the pushing area 7011, the pre-rolling area 7012 is obliquely arranged, and during the movement of the roller 801 in the pre-rolling area 7012, gaps between the rollers 801 are continuously reduced, so that the roller 801 rolls the steel plate, and the longitudinal vertical section of the rolled steel plate is changed into a rectangular isosceles trapezoid;
the roller 801 enters the area where the rolling track 702 is located through an arc track after passing through the pre-rolling area 7012, the roller 801 firstly enters the connection area 7021, the connection area 7021 is arranged in an inclined manner, during the process that the roller 801 travels in the connection area 7021, because the length of the complete rolling area 7022 is greater than that of the pushing area 7011, when the roller 801 is located in the connection area 7021 and moves, the outer wall of the roller 801 is located on two sides of a steel plate which is completely rolled, the roller 801 does not contact with the steel plate at the moment until the roller 801 moves to the tail end of the connection area 7021, the roller 801 begins to contact with the steel plate at the moment, the contact position of the roller 801 and the steel plate is the area which is completely rolled, the roller 801 moves from the side which is completely rolled to the side which is not completely rolled on the steel plate, and then the area where the roller 801 rolls the steel plate last time continuously twice has an overlapping part, that is, a new primary roller 801 covers the rolling area of the steel plate in the previous period of movement of the primary roller 801 in the complete rolling area 7022 and covers the rolling area of the steel plate in the last period of movement of the primary roller 801 in the complete rolling area 7022, the roller 801 sequentially enters the complete rolling area 7022, the skew rolling area 7023 and the reset area 7024 after leaving the connection area 7021, when the roller 801 is located in the complete rolling area 7022, the vertical section of the rolling area to which the steel plate is subjected is rectangular, then when the roller 801 is located in the skew rolling area 7023, the vertical section of the rolling area to which the steel plate is subjected is trapezoidal, and when the last roller 801 is located in the reset area 7024, the vertical section of the rolling area to which the steel plate is subjected is rectangular, the roller 801 leaves the reset area 7024 and enters the propulsion area 7011 again through an arc-shaped track, so that the roller 801 forms a reciprocating movement inside the track;
when the roller 801 is positioned in the rolling track 702, the acting force of the roller 801 on the steel plate is larger than that of the roller 801 positioned in the feeding track 701, and when the roller 801 performs return motion in the rolling track 702 relative to the feeding track 701, the roller 801 has reverse acting force on the steel plate, and the feeding limit assembly 5 is arranged on one side of the steel plate in the expected motion direction;
the oil storage cavity 502 is eccentrically arranged on one side of the movable shaft 501, when the steel plate moves reversely, the steel plate drives the oil storage cavity 502 to deflect relative to the movable shaft 501 through the movable block 504, the pressure of the oil storage cavity 502 on the steel plate is continuously increased during deflection until the oil storage cavity 502 blocks the steel plate to continue moving through the pressure caused by the movable block 504, and the oil storage cavity 502 and the steel plate are kept in a relatively static state;
when the steel plate drives the oil storage cavity 502 to deflect relative to the movable shaft 501 through the movable block 504, the movable block 504 slides in the channel 503 under the pressure of the steel plate until the movable block 504 moves from one end to the other end in the channel 503, the opening of the oil storage cavity 502 at one side adjacent to the steel plate is changed from a closed state to an open state, the rolling oil in the oil storage cavity 502 leaves and is attached to the surface of the steel plate, the opening of the oil storage cavity 502 at one side far away from the steel plate is changed from the open state to the closed state, and therefore the oil outlet of the trapezoid block pipeline is blocked;
when the roller 801 is located inside the feeding track 701, after the roller 801 drives the steel plate to move, the pressure of the steel plate on the movable block 504 disappears, the movable block 504 seals an opening on one side, adjacent to the steel plate, of the oil storage cavity 502 under the action of the spring, and when the rolling oil attached to the steel plate moves relative to the movable block 504 along with the steel plate, the movable block 504 coats the rolling oil on the steel plate, so that the subsequent roller 801 can process the steel plate conveniently.
