[0041] Working process of the roll installation structure:

[0042] The slide table 23 set on the base 2 is slidably connected to the slide rail 11 of the base frame 1. The drive end 52 of the roll 5 is fixedly sleeved on the inner ring of each bearing 32. The control cylinder 421 drives the sliding rod 422 to slide in the arc-shaped slide groove 411, so that the floating connecting block 41 swings around the rotating pin 413 fixed on the frame 43. The spherical groove 412 quickly finds the spherical protrusion 531, and the third fixing screw 533 passes through the ball bearing 4122 set in the top opening 4121 of the spherical groove 412 and is threaded together with the third positioning screw hole 532 on the top of the spherical protrusion 531, so as to realize the radial positioning of the roll 5 and the rapid installation of the roll. The roll gap between the rolls 5 is adjusted by the linear movement module 21. After the first fixing component 22 is fixed and moved, the relative position of the base 2 and the roll 5 is fixed to meet the needs of product production in different fields.
