The split fan-shaped abrasive disc is of an unequal edge structure, the racks are in an oblique straight tooth shape, an included angle between the central line of each rack and a connecting line between the vertex of the rack and the center of the circle of the rounding body is larger than 0 degree, and at least one rack is arranged in parallel with the edge line of the split fan-shaped abrasive disc. The split fan-shaped abrasive disc adopts an unequal-edge structural design, the rack is in an oblique straight tooth shape and has an oblique angle, the center line of the rack is not coincident with or parallel to the connecting line between the vertex of the rack and the center of the circle 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, other material pulping production and the like, in particular to an oblique straight tooth split 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 block is designed to be right and left equilateral, and the edge lines of the two sides of the fan block are coincident with the radius line of the round grinding plate. When the rack is designed to incline, the rack cannot be arranged on the sector plates of the equilateral segments (as shown in figure 1), so that the integrity of the rack is seriously affected, the cutting length and the effective pulping area of the grinding plate rack are reduced, and the pulping 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 oblique straight tooth split type grinding disc, when the included angle between the central line of a rack and the connecting line from the top point of the rack to the center of the circle is designed to be more than 0 degree, the rack can be completely arranged on the split type fan-shaped grinding disc, the cutting length and the effective grinding area of the rack of the grinding disc are improved, and the grinding disc is beneficial to improving the grinding quality and efficiency.
The technical scheme adopted for solving the technical problems is as follows:
an oblique straight tooth split type abrasive disc is formed by enclosing 3-16 split fan-shaped abrasive discs into a whole circle body, a plurality of racks and a plurality of grooves are arranged on the split fan-shaped abrasive disc, each rack is arranged in parallel with the adjacent groove, the split fan-shaped abrasive disc is of an unequal edge structure, the racks are in an oblique straight tooth shape, an included angle between the central line of each rack and a connecting line between the vertex of the rack and the center of the circle of the whole circle is larger than 0 degree, and at least one rack is arranged in parallel with the edge line of the split fan-shaped abrasive disc.
Further, the racks are arranged in parallel with the adjacent grooves, and the included angle between the center line of the groove adjacent and parallel to the racks and the connecting line between the vertex of the groove and the center of the circle of the whole circle is larger than 0 degree.
Further, a crosspiece concentric with the whole circle body or non-concentric circle is arranged in the groove.
The split fan-shaped abrasive disc adopts an unequal-edge structural design, the rack is in an oblique straight tooth shape and has an oblique angle, the center line of the rack is not coincident with or parallel to the connecting line between the vertex of the rack and the center of the circle of the whole circle, and a certain included angle is formed.
Drawings
Fig. 1 is a schematic structural view of a split fan-shaped abrasive sheet according to the prior art.
Fig. 2 is a schematic structural view of a split fan-shaped abrasive sheet according to the present utility model.
Fig. 3 is a schematic view of a structure of a full-round abrasive disc enclosed by the split fan-shaped abrasive disc of fig. 2.
The cutting machine comprises a split fan-shaped abrasive disc, a rounding body, racks, grooves, a central line of the racks, a connecting line from the top of the racks to the center of the rounding body, a split fan-shaped abrasive disc edge line and a crosspiece.
Detailed Description
As shown in fig. 2 and 3, an oblique straight tooth split type abrasive disc is formed by encircling 3-16 split type abrasive disc segments 1 into a whole round body 2, a plurality of racks 3 and a plurality of grooves 4 are arranged on the split type abrasive disc segments 1, each rack 3 is arranged in parallel with the adjacent groove 4, the split type abrasive disc segments 1 are of unequal-edge structures, the racks 3 are arranged in an oblique straight tooth shape and have an inclined angle, the racks 3 can be completely arranged on the same split type abrasive disc segments 1, the included angle between the central line 5 of each rack and the connecting line 6 from the vertex of each rack 3 to the center of the whole round body is larger than 0 degree, and at least one rack is arranged in parallel with the edge line 7 of the split type abrasive disc segments. The included angle between the center line of the groove adjacent to and parallel to the rack and the connecting line between the top of the groove and the center of the circle of the whole circle is larger than 0 degree. A crosspiece 8 concentric or non-concentric with the whole circle is arranged in the groove 4. The racks 3 can be completely arranged on the split fan-shaped grinding disc 1 and the whole round body 2, 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.
