Line pressing device of thin knife slitting line pressing machine for carton processing

The invention relates to the technical field of carton processing, in particular to a line pressing device of a thin knife slitting line pressing machine for carton processing, which comprises a rack, one side of the rack is fixedly connected with a motor seat, and one side of the motor seat is fixedly connected with a driving motor; through the arrangement of the adjusting mechanism, a crank is rotated to drive a rotating rod and two driving bevel gears to rotate, and the two driving bevel gears rotate to drive two driven bevel gears and two bidirectional threaded rods to rotate, so that a threaded block, a sliding plate and a line pressing wheel move, and meanwhile, the sliding plate moves to drive an L-shaped block and a positioning pin to move; due to the fact that the reset spring is in the stretching state, pulling force can be generated on the positioning pin, the positioning pin is pulled to enter the positioning groove, line pressing wheels of different rollers can be conveniently adjusted and matche
