Abstract
The utility model discloses an integral grinding disc with arc teeth, and belongs to the technical field of grinding disc processing. Including the whole circle body of integral structure, be provided with a plurality of rack and a plurality of slot on the whole circle body, every rack and adjacent slot parallel arrangement, its characterized in that: the racks are arc-shaped teeth, and the included angle between the connecting line of the two end points of each rack and the connecting line between the vertex of the rack and the circle center of the rounding body is larger than 0 degree. The utility model adopts an integrated structural design, the rack is arc-shaped and has an inclined angle, the connecting line of two end points of the rack is not overlapped with or parallel to the connecting line between the vertex of the rack and the circle center of the whole circle, and a certain included angle is formed.
Description
Technical Field
The utility model relates to a grinding disc for a disc pulping machine, which is suitable for the fields of pulping and papermaking, density board production, pharmacy, papermaking tobacco sheets, starch production, natural cellulose fiber pulp, synthetic fiber pulp, nitrocellulose seaweed, straw waste, pulping production of other materials and the like, in particular to an arc-tooth integral grinding disc.
Background
The disc refiner is an important device in pulping and papermaking, density board production, pharmacy, papermaking tobacco sheet, starch production, natural cellulose fiber pulp, synthetic fiber pulp, nitrocellulose seaweed, straw waste and other material refining production, and the abrasive disc is a core element for directly performing multiple functions on raw materials such as fibers when the refiner is used for refining (pulping), and has a key effect on the quality of refining.
The circular grinding disc of the disc refiner in the prior art is generally composed of 6 pieces of 60-degree split fan-shaped grinding discs or 8 pieces of 45-degree split fan-shaped grinding discs, and the circular grinding disc is designed in a symmetrical equilateral split manner. The disclosed fan-shaped piece is designed to be right and left equilateral, and the rack is designed to be arc-shaped. Because the adjacent two split fan-shaped abrasive discs are difficult to control the joint of the racks during assembly, the integrity of the racks on the whole grinding surface is caused, the grinding area is reduced, and the grinding quality and efficiency are affected. Therefore, development of a new grinding sheet is needed to solve the above problems while ensuring the beating effect.
Disclosure of Invention
The utility model aims to provide an integral grinding disc with arc teeth, which adopts an integral structure, abandons the design of a split type fan-shaped grinding disc, and can be completely arranged on the whole grinding disc when connecting lines of two end points of an arc-shaped rack are not overlapped with the radius of a whole circle (namely, a certain included angle is formed), so that the cutting length of the rack of the grinding disc and the effective pulping area are improved, and the grinding disc is beneficial to improving the pulping quality and efficiency.
The technical scheme adopted for solving the technical problems is as follows:
the utility model provides an integral abrasive disc of arc tooth, includes the whole circle body of integral structure, be provided with a plurality of rack and a plurality of slot on the whole circle body, every the rack is with adjacent slot parallel arrangement, the rack is the arc tooth shape, every the contained angle between the both ends point line of rack and this rack summit to whole circle body centre of a circle connecting wire is greater than 0 degrees.
Further, the racks are arranged in parallel with the adjacent grooves, and the included angle between the connecting line of two end points of the groove adjacent and parallel to the racks and the connecting line between the vertex of the groove and the circle center of the rounding body is larger than 0 degree.
Further, a crosspiece concentric with the whole circle body or non-concentric circle is arranged in the groove.
The utility model adopts an integrated structural design, the rack is arc-shaped and has an inclined angle, the connecting line of two end points of the rack is not overlapped with or parallel to the connecting line between the vertex of the rack and the circle center of the whole circle, and a certain included angle is formed.
Drawings
Fig. 1 is a schematic structural view of an integrated abrasive sheet of the present utility model.
The gear rack comprises a gear rack body, a gear rack, a groove, a connecting line of two end points of the gear rack, a connecting line from the top point of the gear rack to the center of the gear rack, and a crosspiece.
Detailed Description
As shown in fig. 1, an integral abrasive disc with arc teeth comprises a rounding body 1 with an integral structure, a plurality of racks 2 and a plurality of grooves 3 are arranged on the rounding body 1, each rack 2 is arranged in parallel with the adjacent groove 3, the racks 2 are arranged in an arc tooth shape and have inclination angles, the racks 2 can be completely arranged on the rounding body 1, and an included angle between two end point connecting lines 4 of each rack and a connecting line 5 from the vertex of each rack to the center of the rounding body is larger than 0 degree. The included angle between the connecting line of two end points of the grooves which are adjacent and parallel to the racks and the connecting line between the vertex of the groove and the circle center of the whole circle body is larger than 0 degree. A crosspiece 6 concentric or non-concentric with the whole circle is arranged in the groove 3. The racks 2 can be completely arranged on the rounding body 1, so that the integrity of the racks is improved, the cutting length and the effective pulping area of the grinding disc racks are improved, and the pulping quality and the pulping efficiency are improved.
