Abstract

The invention relates to a tool rest electric adjusting device, which comprises wall boards on the two ends of the tool rest electric adjusting device, a leading screw arranged between the wall boards, and a decelerator arranged outside the wall board on one end of the device and linked with the leading screw, wherein the leading screw is provided with the tool rest, the inside of the tool rest is provided with a gear sleeved on the leading screw, an outer edge of the gear is provided with an engaged tooth, the top end of the tool rest is provided with an air cylinder, the bottom of the air cylinder is connected with a stop shaft, and the stop shaft is positioned right above the gear. Because the tool rest and the gear form the adjusting device through the leading screw for adjustment, and the leading screw and the stop shaft of the gear are electrically controlled, the axial adjustment of the tool rest can be achieved without manual operations, thus the working efficiency is greatly improved and the adjusting accuracy is guaranteed.

Description

technical field [0001] The invention relates to a device for adjusting the axial movement of a knife rest in a printing machine, in particular to a device for adjusting the position of the knife rest in an electric manner. Background technique [0002] At present, in printing machinery, the axial movement adjustment of the knife rest adopts a mechanical adjustment device composed of a rack and an adjustment gear shaft. The multiple knife rests on the equipment are respectively realized by an adjustment structure. When adjusting the position, the staff It is necessary to use a special wrench to insert into the adjusted hole, and apply a large force to move the tool holder to the required position one by one. However, in this way, it is difficult to ensure the accuracy of the adjustment position, and the work efficiency is greatly reduced, which cannot meet the needs of automatic production. Contents of the invention [0003] The purpose of the present invention is to provi...
