Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of die-cutting machines, in particular to a tool replacement device for a die-cutting machine. Background Art
[0002] The die-cutting machine cuts and trims printed paper. When the cutter of the die-cutting machine is not sharp after use, the cutter needs to be replaced. For example, in a fully automatic carton die-cutting machine (patent number: CN202222638016.8) that is easy to replace the cutter, the cutter is installed in the sliding groove and fixed by a fixing pin passing through the positioning hole. However, the cutter and the sliding groove are the same size, which makes the installation of the cutter more difficult. If a gap fit is used for installation, there will be a gap between the cutter and the sliding groove. When the cutter cuts the printed paper, the gap between the cutter and the sliding groove causes the cutter to deviate slightly, so that the cutter and the printed paper are in a non-perpendicular state, which not only causes the cut paper to have burrs, but also changes the force on the cutter, thereby reducing the service life of the cutter.
[0003] Therefore, we propose a tool changing device for a die-cutting machine. Utility Model Content
[0004] The purpose of the present utility model is to provide a tool replacement device for a die-cutting machine to solve the problems raised in the above background technology.
[0005] The top of described sliding panel also is provided with an interlocking structure, and the interlocking structure is hinged on the base plate, is fixed with a backing pin on the interlocking structure, and an end of sliding panel withstands on the backing pin of interlocking structure.
[0006] Furthermore, a groove is provided on the base, a spring is provided in the groove, and a horizontal plate is provided on the top of the spring.
[0007] Furthermore, the limiting plate is fixedly connected to the threaded sleeve, and the cross-sections of the limiting plate and the positioning groove are both circular.
[0008] Furthermore, the bottom end of the guide rod is fixedly connected to the top of the fixing seat, and the bottom end of the cylinder is connected to the top of the fixing seat through the through hole.
[0009] Furthermore, the rotating shaft passes through the outer wall of the fixing seat and is fixedly connected to the limiting plate, and the rotating shaft and the fixing seat are movably connected, and a handle is provided at the right end of the rotating shaft.
[0010] Compared with the prior art, the beneficial effects of the present invention are: tightening the second threaded rod to fix the limit plate, thereby fixing the threaded sleeve so that the threaded sleeve cannot rotate, fixing the tool seat so that the tool seat and the cutter are always in a vertical state, better cutting the printed paper, and improving the cutting quality of the paper. At the same time, the cutter is in a vertical state, and when cutting the printed paper, the force direction of the cutter will be perpendicular to the printed paper, thereby extending the service life of the cutter.
