Description

Dust removal device

The present invention relates to a dust removing device, and more particularly to a cutting powder produced by removing a cutting device.

Referring to Figures 10 and 11, in order to cut the base material (the continuous sheet of film, paper, etc.) 41 into a strip-shaped body 42 having a predetermined substrate width, a cutting blade 43 having a rotatably driven type is generally used. Cutting device 44. The substrate 41 continuously travels in the direction of the arrow R, and is continuously cut by several tens of meters by being fixed at a certain interval on a plurality of cutting blades 43 that are rotationally driven (using a driving device outside the drawing) 45. ~ Substrate 41 of several thousand meters in length.

When the substrate 41 is cut, a dicing powder is generated and adhered to the edge of the dicing blade 43 and the strip 42.

It is conventional to use an air gun in order to remove the cutting powder thus attached. However, when the cutting powder adhering to the cutting blade 43 and the strip 42 is blown off by the air gun, it may scatter to the surroundings and may adhere to the base material 41 and the strip 42 again.

Alternatively, as shown in Figs. 10 and 11, even when a suction type dust removing device including a cover 46 that surrounds the cutting blade 43 and the suction pipe 47 is used, it is difficult to easily attach the gas to the arrow direction U. The cutting powder is removed, and the cutting blade 43 and the strip 42 are not sufficiently cleaned. Further, in the conventional cutting device 44, the installation space is narrow, and it is difficult to provide the suction type dust removing device as shown in Figs.

Here, the inventors of the present invention also reviewed the applicability of the proposed gas-spraying suction type dust removing device (No. 2820599).

In the dust removing device described in the above-mentioned Japanese Patent No. 2820599, if it is only gently dropped on the surface of the traveling sheet, it can be surely removed, in particular, gently dropped on a flat wide surface. In the case of dust, it can be easily and surely removed.

However, in the cutting device 44 as shown in Figs. 10 and 11, it is known that it is difficult to sufficiently remove dust. One is because the cutting powder is relatively strong attached to the edge of the cutting blade 43 or the strip 42. Second, since the cutting powder is located at a complicated attraction, it is difficult to effectively attract.
