Technical Field

[0001] The utility model relates to the technical field of polarizer processing, in particular to a dust collection structure for the processing of a polarizer cylinder knife. Background Art

[0002] The full name of a polarizer is a polarization light sheet. The imaging of a liquid crystal display must rely on polarized light. All liquid crystals have two polarization light sheets, front and back, closely attached to the liquid crystal glass, forming a liquid crystal sheet with a total thickness of about 1 mm.

[0003] During the processing of a polarizer, long-term use causes a large amount of static charges to be generated by the contact between the cylinder knife and the polarizer material. At the same time, heat, processing dust and fine chips are generated by the friction between the tool and the material. In the existing processing conditions and methods, a simple blowing and suction method is used to eliminate or recover the generated static charges, heat and processing dust. However, in a conventional dust collection structure, dust is often likely to accumulate in the cylinder knife processing chamber and is difficult to clean up. Summary of the Utility Model

[0008] One end of the dust collection pipeline is connected to the dust collection port on the top plate, and a negative pressure source is connected to the dust collection pipeline.

[0009] Further, one end of the side plate extends out of the arc-shaped notch ends of the bottom plate and the top plate, and a group of cylindrical cutter blowing holes is arranged in the area where the side plate extends out of the bottom plate and the top plate.
