Abstract
The invention provides a cutting blade for producing regenerative polyester staple fibers. The cutting blade comprises a cutter body and a cutting edge. The cutter body is in the shape of a cuboid and the cutting edge is in the shape of a triangular prism. The two ends of the triangular prism are isosceles triangles. The side surfaces of the triangular prism are squares. The length of the lateral edges of the triangular prism is the same as the length of the cutter body. The length of the bottom edge of the isosceles triangles of the end faces of the triangular prism is the same as the thickness of the cutter body. The cutting blade prevents cut staple fibers from being attached thereto, can attract partial stable fiber powder, and guarantees uniform stress in the cutting process; the cutting blade is not restricted by direction in installation, so that the accident of blade breakage caused by human installation errors can be prevented and the service life of the blade is prolonged. The cutting blade is reasonable in structure, is simple and practical and is worthy of promotion.
Description
Technical field
The present invention relates to the production equipment technical field of chemical fibre industry, more specifically, relate to the device that a kind of fibre bundle cuts off, particularly relate to a kind of be used in Regenerated Polyester Staple Fiber support one's family produce in cutter blades in fibre cutting equipment.
Background technology
In recent years, Regenerated Polyester Staple Fiber dimension is in great demand, and output increases fast.Cut-out, packing are the last two procedures in polyester staple fiber production process, and for reaching the demand of final products to raw material, polyester staple fiber requires to have accurate shearing length, ensure that shearing length is between 38 ~ 65mm.And for the production line of existing continuous operation, because operating load is large, output is high, existing cutoff tool, due to structure of the cutter body, operationally easily produces distortion, breaking, once there is a slice breaking, the fibre length cut out will be over-length fibre.At present, cutting machine adopts wheel pressure type cutter blades mostly, and cutter blades many employings single-blade face structure, be exactly usually said technique in calligraphy cutter, advantage is that cutter mill is convenient, and knife edge angular is easy to control, and shortcoming is due to single-blade face, directionality is installed, once pacify wrong direction, with regard to breaking during operation; Secondly there is obvious skewness when this cutter is stressed, namely blade significantly offsets to more flat side, accelerates edge of a knife wearing and tearing.
Summary of the invention
The object of this invention is to provide a kind of production Regenerated Polyester Staple Fiber Wesy cutter blades, the not sticky cutter of the staple fibre of cut-out can be made, and adsorbable some staple fiber dimension powder, uniform force in cutting process, and the directionality that there is not installation, eliminate artificial setup error and cause breaking accident, add the service life of blade, rational in infrastructure, brief and practical, has promotional value.
The object of the invention is to be achieved through the following technical solutions, a kind of production Regenerated Polyester Staple Fiber Wesy cutter blades, comprise cutter hub and blade, described cutter hub shape is cuboid, described cutting edge shape is tri-prismoid, and tri-prismoid two ends are isosceles triangle, and the side of tri-prismoid is square, the incline length of tri-prismoid is identical with cutter hub length, and the isosceles triangle base length of tri-prismoid end face is identical with cutter hub thickness.
Further, described cutter hub is cuboid.
Further, the length of described cutter hub is 120mm, and width is 16mm, and thickness is 2mm.
Further, before and after described cutter hub, both sides correspondence is provided with groove, and groove longitudinal section is arc, and the length of groove is 100mm, and width is 2mm.
Further, the isosceles triangle drift angle of described blade end face and the blade basil are 18-24 °.
Compared with prior art, the present invention has following beneficial effect:
The first, band provided by the invention fluted production Regenerated Polyester Staple Fiber Wesy cutter blades, because the both sides of cutter blades are all with groove, trench length is 100mm, and width is 2mm, can make the not sticky cutter of the staple fibre of cut-out, and adsorbable some staple fiber dimension powder;
Second, compared with using cutter with tradition, cutter provided by the invention is a kind of uniform force, there is the blade of geometry symmetry, make its uniform force in cutting process, and there is not the directionality of installation, eliminate and cause breaking accident because of artificial setup error, add the service life of blade, and be easy to implement, there is promotional value;
3rd, blade of the present invention is equipped with two blades, and two edge bevel angles are consistent, there is symmetrical structure, make its uniform force in cutting process, and there is not the directionality of installation, eliminate and cause breaking accident because of artificial setup error, add the service life of blade.
Accompanying drawing explanation
Fig. 1 is the structural representation of production Regenerated Polyester Staple Fiber Wesy of the present invention cutter blades;
In figure: 1-cutter hub; 2-groove; 3-blade; The 4-edge of a knife; 5-split.
Detailed description of the invention
Below in conjunction with drawings and Examples, further detailed description is done to the present invention.
As shown in Figure 1, a kind of production Regenerated Polyester Staple Fiber Wesy cutter blades, comprises cutter hub 1 and blade 3.
Cutter hub shape is cuboid.
Cutting edge shape is tri-prismoid, and tri-prismoid two ends are isosceles triangle, and the side of tri-prismoid is square.
The incline length of tri-prismoid is identical with cutter hub length, and the isosceles triangle base length of tri-prismoid end face is identical with cutter hub width.
Cutter hub is cuboid.The length of cutter hub is 120mm, and width is 16mm, and thickness is 2mm.
Before and after cutter hub, both sides correspondence is provided with groove 2, and groove longitudinal section is arc, and the length of groove is 100mm, and width is 2mm.
The isosceles triangle drift angle of blade end face and the blade basil are 18-24 °.
As can be seen from Fig. 1, a kind of cutter blades be used in polyester staple fiber production in fibre cutting equipment, the cutter hub 1 of blade is provided with twolip face, the both sides of described cutter blades cutter hub are all with groove 2, both sides are respectively equipped with edge bevel 3, the both sides blade basil is identical, and two edge bevel intersect formation edge of a knife 4(or are called the knife edge), the inclination angle between each edge bevel and split 5 is 9 ~ 12 °.
A kind of cutter blades be used in polyester staple fiber production in fibre cutting equipment provided by the invention, because the both sides of cutter blades are all with groove, trench length is 100mm, width is 2mm, the not sticky cutter of the staple fibre of cut-out can be made, and adsorbable some staple fiber dimension powder, in addition because the both sides of cutter blades are equipped with blade, two edge bevel angles are consistent, there is symmetrical structure, make its uniform force in cutting process, and there is not the directionality of installation, eliminate and cause breaking accident because of artificial setup error, add the service life of blade.As mentioned above, the present invention can be realized preferably.
