The utility model has the following contents:
the utility model aims at prior art's defect, provide a riveting formula kneader blade subassembly, the assembly precision is high, can not appear pressing from both sides paper in the use, the not hard up scheduling problem of blade group, has improved shredded paper efficiency, the cost is reduced.
Realize the utility model discloses the technical scheme of purpose is: the utility model provides a riveting formula kneader blade subassembly, includes arbor and is a plurality of blade group that the spiral encircles along arbor axial, the arbor includes two at least and sets up from top to bottom, the blade group includes two mirror symmetry's blade, two blades become an organic whole through the riveting, be equipped with the spacer between per two sets of blade group, the blade group crisscross cooperation on two arbors forms the cutting passageway of paper.
The blade is provided with a plurality of riveting holes so as to rivet and press the two blades into an integral blade.
The blade is circular, and its outer fringe circumference evenly distributed has a plurality of cutting edge, the one side that the blade outer fringe is close to the cutting edge is straight section, and difficult the skidding improves shredded paper efficiency.
The center of the blade is provided with a polygonal shaft hole matched with the cutter shaft, the shaft hole is provided with a yielding groove, and the shaft hole is not easy to deform when riveting is carried out due to the existence of the yielding groove.
The thickness of the blade is 2.5 mm.
The blade groups on the upper cutter shaft and the lower cutter shaft are arranged opposite to the spacer bush.
The utility model discloses riveting formula kneader blade subassembly's beneficial effect is:
(1) the utility model provides a riveting formula kneader blade subassembly, wherein every blade group becomes an organic whole through the riveting by two mirror symmetry's blade, has improved the assembly precision, and the paper clamping scheduling problem can not appear in the use, has improved shredded paper efficiency, the cost is reduced.
(2) The utility model discloses a one side that the blade outer fringe is close to the cutting edge is straight section, and the paper is difficult for skidding, improves shredded paper efficiency.
(3) The utility model discloses a be equipped with the groove of stepping down on the shaft hole, shaft hole non-deformable when the existence in groove of stepping down makes the riveting.
Description of the drawings:
figure 1 is a schematic structural diagram of the present invention,
figure 2 is a schematic view of the structure of the blade,
fig. 3 is a schematic structural view of the blade set.
In the figure: 1 arbor, 2 blade groups, 3 spacer bushes, 4 groove of stepping down, 5 cutting edges, 6 straight sections, 7 blades, 8 riveting holes, 9 shaft holes.
The specific implementation mode is as follows:
the following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be clearly and clearly defined.
Referring to fig. 1, the riveting type paper shredder blade assembly comprises a cutter shaft 1 and a plurality of blade sets 2 spirally surrounding along the axial direction of the cutter shaft 1, wherein the cutter shaft 1 is provided with at least two blades and arranged up and down, the blade sets 2 comprise two blades 7 in mirror symmetry, the two blades 7 are integrated through riveting, and a spacer 3 is arranged between every two blade sets 2. The blade group 2 and the spacer 3 on the upper and lower two knife shafts 1 are arranged oppositely, and the specific arrangement mode can be as follows: the blade group 2 on the upper cutter shaft 1 is inserted into a groove formed by the spacer bush 3 on the lower cutter shaft 1 and the two adjacent blade groups 2. The blade groups 2 on the two cutter shafts 1 are matched in a staggered way to form a cutting channel of paper.
See fig. 2, blade 7 is circular, and thickness is 2.5mm, is equipped with a plurality of riveting hole 8 on it to become integrative blade with two blade 7 riveting, the assembly precision is high, and the figure of riveting hole 8 can be decided according to actual need. A plurality of cutting edges 5 are uniformly distributed on the outer edge of the blade 7 in the circumferential direction, and one side, close to the cutting edges 5, of the outer edge of the blade 7 is a straight section 6, so that paper is designed not to slip easily, and paper shredding efficiency can be improved. The center of the blade 7 is provided with a polygonal shaft hole 9 matched with the cutter shaft 1, the shaft hole 9 is provided with a yielding groove 4, and the shaft hole 9 is not easy to deform during riveting due to the existence of the yielding groove 4.
Referring to fig. 3, the blade group 2 is formed by riveting and pressing two blades 7 into an integral blade, and the blades 5 of the blade group 2 on the same cutter shaft 1 are obliquely arranged and uniformly distributed along the outer edge of the blade group 2 in sequence.
Before installing the riveting type paper shredder blade component, two blades 7 with mirror symmetry are riveted into a whole to form a blade group 2, then the blade group 2 and the spacer bush 3 are sequentially installed on the cutter shaft 1, and the blade group 2 spirally surrounds along the axial direction of the cutter shaft 1. After the blade groups 2 and the spacer bushes 3 are sequentially installed on the two cutter shafts 1, the two cutter shafts 1 are arranged up and down correspondingly, the blade group 2 on the upper cutter shaft 1 is inserted into a groove formed by the spacer bush 3 on the lower cutter shaft 1 and the two adjacent blade groups 2, and the blade groups 2 on the two cutter shafts 1 are matched in a staggered mode to form a cutting channel of paper. And then the assembled cutter is tightly connected with a paper shredder.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
