High-speed vacuum coating online cutting device

Abstract

The invention provides a high-speed vacuum coating online cutting device, which belongs to the technical field of coating processing. The high-speed vacuum coating online cutting device solves the problem that the prior cutter has poor cooling effect when cutting coated films and sheets. The high-speed vacuum coating online cutting device comprises a rotating shaft, a tool rest and a power mechanism connected with the rotating shaft, wherein the tool rest is fixedly arranged on the rotating shaft, the outer end part of the tool rest is provided with a cutting blade, the power mechanism drives the rotating shaft to rotate radially so as to control the cut-in of the cutting blade, the tool rest is made from a heat conduction material and is internally provided with a cooling passage, the rotating shaft is provided with a cooling device for providing cooling liquid, and two ends of the cooling passage are connected with the cooling device through a cooling pipe so as to form a closed circulation path. The cutting device is provided with a cooling structure to cool the cutting blade, and the cooling effect is good so that the service life of the cutting blade is prolonged. Simultaneously, a cutting blade adjusting device is arranged on the cutting device for adjusting the position of the cutting blade so as to adjust the cutting width of the films or the sheets.

Description

technical field [0001] The invention belongs to the technical field of mechatronics, and relates to a device for cutting a wide-width film or sheet at high speed under a closed vacuum condition, in particular to a high-speed vacuum coating online cutting device. Background technique [0002] The high-vacuum high-speed flexible roll-to-roll coating machines in various countries in the world have not had this device for synchronous multi-winding after slitting online, and all of them are equal to one-to-one. That is, one unwinding and one winding, that is, there is no online slitting device. Due to the increasingly fierce competition in the vacuum coating industry, our company designed and manufactured the high-speed and high-vacuum flexible winding coating machine based on the original design, in order to better reduce energy consumption and at the same time greatly improve the production efficiency. Developed a high-speed high-vacuum online slitting synchronous multi-windin...

AI Technical Summary

Problems solved by technology

Under vacuum conditions, the heat generated by the friction between the slitting knife and the slit film or sheet is too large to dissipate heat. The frictional heat generated during slitting cannot use air for heat transfer, and the heat dissipation effect is poor, causing the It will heat up quickly and burn the film, so it cannot be cut online under vacuum conditions

In addition, after slitting, the edge of the metallized film is warped when it is rolled, and the slitting blade is cut with a fixed edge for a long time, which makes the slitting blade dull.
