Definitions
- the present invention relates to a papermaking elastic belt used for pressure dehydration treatment of wet paper in fields such as the papermaking industry, and more particularly to a papermaking elastic belt having a drainage groove on the surface. .
- FIG. 4 shows a cross-sectional view of a papermaking elastic belt 1 having a large number of drain grooves 2.
- the groove width dimension of the groove 2 of the papermaking elastic belt 1 is reduced in order to avoid the trace of the groove 2 on the wet paper.
- the groove width dimension is 0.6 to 1.5 mm.
- the elastic belt 1 for papermaking having the drainage groove 2 on the surface As another required characteristic for the elastic belt 1 for papermaking having the drainage groove 2 on the surface, it is possible to mention a drainage property in which the water squeezed from the wet paper is instantaneously discharged from the groove 2 of the belt 1 to the outside. . If the belt 1 rotating at a high speed does not drain from the groove 2 until it rotates once, the wet paper will be re-moistened, and the wet paper will lose its water-squeezing performance.
- the groove width is as narrow as about 0.6 to 1.5 mm, cooling of the processed part with cooling water becomes unstable, and chips are discharged smoothly.
- the surface roughness of the groove wall was about 3 to 4 / ⁇ ⁇ . The present inventor has found that when the surface roughness of the groove wall surface exceeds a predetermined value, the resistance to water flow increases, and paper dust tends to adhere, thereby reducing the water squeezing performance of the elastic belt. It was.
- An object of the present invention is to provide an elastic belt for papermaking that can exhibit good water squeezing performance.
- the surface roughness of the wall surface of the drainage groove is an arithmetic average roughness (Ra) defined by Japanese Industrial Standard CFIS-B0601). It is characterized by being ⁇ ⁇ m or less.
- the drainage groove has a groove bottom curved downward. With such a drainage groove, it is possible to suppress the occurrence of cracks in the elastic belt starting from the bottom of the groove.
- the width dimension of the groove is, for example, 0.6 to 1.5 mm.
- FIG. 1 is a diagram showing a state in which grooving is performed on a papermaking elastic belt using a rotary blade.
- FIG. 2 is a cross-sectional view showing a drainage groove of a papermaking elastic belt according to an embodiment of the present invention.
- FIG. 3 is a cross-sectional view showing a drain groove of a papermaking elastic belt according to another embodiment of the present invention.
- FIG. 4 is a cross-sectional view showing a papermaking elastic belt having a drainage groove.
- FIG. 1 shows a state where a groove force is applied to the elastic belt 51 using the rotary blade 50.
- a coolant is sprayed to the portion of the elastic belt 51 located in the groove cover portion and the blade portion of the rotary blade 50 via the coolant supply pipe 52. If the groove is machined while cooling the machined part in this way, the melting of the elastic belt 51 due to frictional heat can be suppressed, so that the shape and dimensions of the finally obtained groove are stable, and the surface roughness of the groove is further improved. It also improves.
- FIG. 2 shows an example of the drainage groove of the papermaking elastic belt according to one embodiment of the present invention.
- the drainage groove 10 shown in the figure has a rectangular cross-sectional shape, and the surface roughness of the groove wall surface (average roughness Ra defined by Japanese Industrial Standards) is 2.0 ⁇ m or less.
- FIG. 3 shows another example of the drainage groove of the papermaking elastic belt according to another embodiment of the present invention.
- the drainage groove 11 shown in the figure has a bottom shape that is convexly curved by directing downward, and the surface roughness of the wall surface of the groove is 2. or less. If the drainage groove 11 has a curved bottom shape as in this embodiment, the occurrence of cracks starting from the corner portion of the groove bottom can be suppressed.
- the temperature of the cooling liquid sprayed on the processed portion is lowered. If the temperature of the cooling liquid is lowered, the generation of frictional heat can be more effectively suppressed, so that the elastic belt can be prevented from melting.
- the preferred coolant temperature is 10 ° C or lower.
- the inventor of the present application conducted the following caloric test in order to investigate the relationship between the temperature of the coolant and the surface roughness of the groove wall surface. Electro slitting stones and metal saws were used as slitters for the groove cage.
- Coolant 10-50kgZcm 2 pressure water
- the surface roughness was measured with a surface roughness profile measuring device (Surfcom 733A: manufactured by Tokyo Seimitsu Co., Ltd.). As is apparent from the results in Table 1, when the coolant temperature is 10 ° C or less, the surface roughness of the groove wall surface is 2 m or less.
- the inventor of the present application uses each of the neutral belts having a groove wall surface roughness of 0.7 m, 2 m, 3 m, and 4 ⁇ m in a newspaper press, and visually observes the groove wall stain. Confirmed the level. The results are shown in Table 2 below.
- the present invention can be advantageously used for an elastic belt for papermaking having a drainage groove.
