The utility model discloses a novel abrasive disc can also make further improvement and prescribe a limit: wherein the cross section of the tooth is a parallelogram.
The utility model discloses a novel abrasive disc can also make further improvement and prescribe a limit: wherein the inner circle of the annular grinding sheet body is provided with a 60-degree inclination angle.
The utility model discloses a novel abrasive disc can also make further improvement and prescribe a limit: twelve fixing holes are formed in the annular grinding sheet body, four fixing holes are arranged at the inclination angle of the inner circle of the annular grinding sheet body at equal intervals, and the other eight fixing holes are arranged in the middle of the annular grinding sheet body at equal intervals.
The utility model discloses a novel abrasive disc can also make further improvement and prescribe a limit: wherein, the height is 35mm about the tooth.
The utility model relates to a novel abrasive disc of papermaking usefulness, because the tooth on every fan-shaped abrasive disc is 18 with the central line contained angle of abrasive disc, state the tooth width and be 20mm, the tooth space is 30mm, consequently, can increase the dwell time of thick liquids at annular abrasive disc to improve fibrous microfibrillar degree, have the fixed orifices on the fan-shaped abrasive disc, make things convenient for fan-shaped abrasive disc installation admittedly, consequently, the utility model discloses a novel abrasive disc profile of tooth design is simple, changes simple to operate and can improve fibrous microfibrillar degree.

The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, a novel abrasive sheet for papermaking, comprising: at least six integrated into one piece's fan-shaped abrasive disc 2 forms a closed annular abrasive disc body 1 between the abrasive disc, is provided with the fixed orifices 3 that a plurality of equidistant settings on the annular abrasive disc body 1, every the abrasive disc contains a plurality of teeth 4, tooth 4 runs through the arc inside and outside edge of annular abrasive disc body 1 and with 6 contained angles of central line of annular abrasive disc body 1 are 18, tooth 4 is wide to be 20mm, and tooth 4 interval is 30mm, fixed orifices 3 are in the thickness direction of abrasive disc runs through annular abrasive disc body 1.
Wherein the teeth 4 have a parallelogram-shaped cross-section.
Wherein the inner circle of the ring-shaped grinding sheet body 1 is provided with a 60 DEG inclination angle 5.
Twelve fixing holes 3 are arranged, four of the fixing holes are arranged at the inclination angle 5 of the inner circle of the annular grinding plate body 1 at equal intervals, and the other eight fixing holes are arranged in the middle of the annular grinding plate body 1 at equal intervals.
Wherein, the height of the teeth 4 is 35 mm.
The utility model relates to a novel abrasive disc of papermaking usefulness, because tooth 4 on every fan-shaped abrasive disc 2 is 18 with the 6 contained angles of central line of abrasive disc, state tooth 4 wide and be 20mm, tooth 4 interval is 30mm, has increased the density of tooth 4, and tooth 4 on every fan-shaped abrasive disc 2 is 18 settings with the 6 contained angles of central line of abrasive disc simultaneously, can increase the dwell time of thick liquids at the annular abrasive disc to improve fibrous microfibrillar degree, have fixed orifices 3 on the fan-shaped abrasive disc 2, make things convenient for fan-shaped abrasive disc 2 to install admittedly, consequently, the utility model discloses a novel 4 shape designs of abrasive disc tooth are simple, change simple to operate and can improve fibrous microfibrillar degree.
