Abstract

The invention discloses an automatic rising-lowering rewinder of a paper pressing roller. The automatic rising-lowering rewinder comprises a rack, wherein a front bottom roller and a rear bottom roller are arranged on the bottom of the rack, the paper pressing roller is arranged above the front bottom roller and the rear bottom roller, the paper pressing roller is connected with one end of a pulley block, the other end of the pulley block is connected with a lifting cylinder, the lifting cylinder is fixed on the rack, and the height of the paper pressing roller is adjusted up and down along with rising and falling of the lifting cylinder. Compared with a rewinder with the paper pressing roller being regulated manually before, the automatic rising-lowering rewinder of the paper pressing roller adjusts rising and falling of the paper pressing roller through an air-actuated control system by using the lifting cylinder, and the compactness of a scroll can be better controlled.

Description

technical field [0001] The invention relates to papermaking equipment, in particular to a rewinder with automatic lifting of paper pressing rollers. Background technique [0002] At present, in the paper cutting process of the rewinder, the pressure roller is generally controlled by manual lifting, and the pressure of the pressure roller on the paper roll is adjusted to control the tightness of the paper roll. This method is labor-intensive, and due to artificial The tightness of the factor paper roll is not necessarily uniform. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rewinding machine in which the paper pressing roller can be lifted and lowered automatically. [0004] The technical solution of the present invention is: a rewinding machine with automatic lifting of the pressing roller, including a frame, a front bottom roller and a rear bottom roller are arranged at the bottom of the frame, and a paper...
