Detailed Description

The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the drawings in the embodiment of the present invention. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the invention.

Referring to fig. 1 and 2, the present invention provides a lower lifting pinch roll device, which comprises a frame 1, an upper pinch roll 2, a lower pinch roll 3, a lifting block 4 and a lifting driving member 5, wherein the frame 1 comprises a base and two supporting plates relatively fixed on the base, and two ends of the upper pinch roll 2 are respectively mounted on the two supporting plates of the frame 1 through bearing seats. The lower pinch roll 3 is arranged on the frame 1 and is positioned right below the upper pinch roll 2. Two ends of the lower pinch roll 3 are respectively installed on the two lifting blocks 4 through bearing seats, a lifting groove 11 is formed in each supporting plate of the rack 1, each lifting block 4 is arranged in each lifting groove 11 in a liftable mode, two lifting driving pieces 5 are arranged and are respectively installed on the base of the rack 1 relatively, a piston rod of each lifting driving piece 5 is correspondingly connected with one lifting block 4, and therefore the two lifting blocks 4 are driven to synchronously lift.
