Description

Polaroid RTS automatic cutting machine loading attachment

Technical Field

The utility model belongs to the technical field of the cutting equipment and specifically relates to a polaroid RTS automatic cutout machine loading attachment is related to.

Background

The polarizer is called a polarizing plate, is an optical element capable of converting natural light into polarized light, and is widely applied to the field of liquid crystal display. In the production process of the polarizer, in order to cut the rolled polarizer into a desired shape and size, an automatic cutting machine is generally required, and according to the difference of cutting modes, the cutting machine is generally divided into an rts (roll to sheet) type cutting machine and an rtc (roll to cut) type cutting machine, and the two cutting machines have basically the same operation principle, and the difference lies in the selection and distribution of cutting blades. The cutting machine generally has a feeding device, which is used to separate and introduce a rolled polarizer raw material into the cutting machine in a strip shape for being cut by a cutting blade.

Among the prior art, chinese utility model patent that publication number is CN208729937U discloses a guillootine material loading drive mechanism, including the mount, the mount is installed on the guillootine, is provided with the recess on the mount, and mount recess top one side fixed mounting has last spacing board, and mount recess below one side fixed mounting has lower spacing board, goes up the joint between spacing board and the lower spacing board and has the draw-in groove, and draw-in groove fixed mounting is on the material loading roll axis, and the draw-in groove is formed by two circular connecting plate combinations.
