s24: the third motor is driven reversely and the second scissor type expansion bracket is synchronously driven to contract until the three old conveying rollers are mutually close under the drive of the regulating roller and the second clamping head of the first clamping head;
s25: continuously contracting the first scissor type expansion bracket until three old conveying rollers are dragged to the roller changing slideway, and loosening the old conveying rollers by a second clamping head of the first clamping head;
the step S5 specifically comprises the following steps:
s51: the ends of three new conveying rollers positioned on the roller changing slideway are respectively clamped and fixed by a first clamping head and two second clamping heads, and the first scissor type expansion bracket is extended until the three new conveying rollers are pushed onto the regulating roller;
s52: a plurality of horizontal screw rods are driven to rotate through a third motor, and the second scissor type telescopic frames are synchronously extended until the regulating rollers, the first clamping heads and the second clamping heads drive three new conveying rollers to be aligned with three corresponding installation positions on a production line respectively;
s53: and continuing to extend the first scissor type telescopic frame until the three new conveying rollers are respectively pushed to the corresponding installation positions on the production line.
10. The roll changing method according to claim 9, wherein step S3 specifically includes: the plurality of second rotating shafts are driven by the second motor to rotate until the plurality of top supporting plates deflect to vertical positions, the top supporting plates support old conveying rollers on the conveying roller, and the old conveying rollers automatically slide to a second vertical plate of the roller outlet slideway along the inclined surface of the top supporting plates to be collected;
the step S4 specifically comprises the following steps:
s41: lifting the movable baffle through a lifting oil cylinder;
s42: the first motor drives the first rotating shaft to rotate, and simultaneously three new conveying rollers on the roller conveying slideway can automatically slide into the three sector gaps in sequence and automatically convey the three new conveying rollers to the top supporting plate;
s43: and driving a plurality of second rotating shafts to reversely rotate through a second motor until three new conveying rollers respectively and automatically fall into three annular grooves on the conveying roller, and finally lowering the movable baffle.
