Problems solved by technology
[0002] When winding the slit paper tape, since the diameter of the paper roll gradually increases from small to large, the distance between the slitting knife holder and the paper roll axis must be greater than The radius of the paper roll and the position of the slitting knife holder must be set very high, but when the diameter of the paper roll is small, if the position of the slitting knife holder is far from the paper roll, it is easy to cause problems such as paper tape slipping or breaking

The invention discloses a lifting mechanism of a knife rest of a splitting machine. The lifting mechanism comprises a rack, a knife rest rod and the knife rest and also comprises a nut rod, a motor, a screw rod and a universal joint, wherein the knife rest rod is rotatably arranged on the rack; the knife rest is arranged at the end part of the knife rest rod; the nut rod is rotatably connected with the knife rest rod; the motor is fixedly arranged on the rack; the screw rod is matched with the nut rod; the universal joint is fixedly arranged on a rotor of the motor; and the universal joint is connected with the rotor of the motor and the screw rod respectively. The lifting mechanism disclosed by the invention has the advantages that the advantages that due to adoption of the structure with the screw rod and the nut, and by matching with the universal joint, the height of the knife rest can be conveniently adjusted, and the defect that the height of the knife rest of the existing splitting machine can not be stably adjusted is overcome.
Description
technical field [0001] The invention relates to a paper tube machine, in particular to a lifting mechanism for a knife rest of a slitting machine. Background technique [0002] When winding the slit paper tape, since the diameter of the paper roll gradually increases from small to large, the axis distance between the slitting knife holder and the paper roll must be greater than the radius of the paper roll, and the position of the slitting knife holder must be set very carefully. High, but when the diameter of the paper roll is small, if the position of the cutter holder is far from the paper roll, it is easy to cause problems such as paper tape slipping or breaking. Contents of the invention [0003] The purpose of the present invention is to provide a cutting machine knife rest lifting mechanism capable of adjusting the height of the knife rest. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a cutting machine k...
