Roller type knife holder

Abstract

The present invention discloses a roller knife holder, comprising a roller knife holder body and a rib plate. A flange plate is mounted on one end of the roller knife holder body. A guide rod mounting hole is provided on the roller knife holder body, and the guide rod is mounted in the guide rod mounting hole. Step grooves and screw holes are provided on the upper and lower sides of the roller knife holder body. The roller knife holder of the invention has a cylindrical exterior and is mounted in a mounting hole of the die-cutting machine base plate. It can rotate and move axially in a linear manner, thereby facilitating the rotation of the lower cutter shaft to the upper installation, improving the convenience of tool installation, and realizing the overall axial adjustment of the cutter holder assembly, thereby improving the convenience and accuracy of adjusting and aligning the cutters of each cutter holder assembly. Eight mounting holes are machined on the cutter holder body for mounting the guide rod, ensuring the precise positioning of the cutter shaft slider, thereby improving the accuracy of cutter shaft installation. Because the cutter holder is an integrally machined part, it can improve the installation accuracy of the motor and reducer.
