    A rotatable cutter spindle for cutting chips of predetermined length has a supporting body having an axis, and a plurality of cutters mounted on the body in spaced relationship to one another and inclined relative to the axis of the body. Each of the cutters includes an acute angle with the axis and has a leading and a trailing end and defines cutting angles which differ from one to another of these ends. Each of the cutters has alternately arranged radially outer cutting edges and radially inner cutting edges of which the radially inner cutting edges are formed by grooves which are provided in the cutters and which have a width that increases from the leading end toward the trailing end of the cutter. The radially outer cutting edges are arranged at a first common circular surface, whereas the radially inner cutting edges are arranged at a second common circular surface.

    专利说明:

    The invention relates to the woodworking industry, in particular to the equipment according to P (EOIZVODST8U
    flat wood shavings.
    A device for processing wood into chips is known, comprising a housing, knife holders and knives ij.
    Also known is a knife shaft for making flat wood shavings containing continuously located obliquely to the axis of the knife hall with a variable chip angle from the leading end of the knife to the next and forming knives with the axis of the knife shaft sharp oblique cutting angle, radially above the cutting edge, whose cutting edges are located on the same circle.
    The disadvantages of the known devices are low productivity, quality and chip quality.
    The purpose of the invention. - increased productivity and chip quality.
    The goal is achieved by the fact that the front face of each knife is made with successively alternating along the length of the knife transverse grooves with increasing from the leading end of the LEUH9 from nominal to maximum depth with finishing of sequentially alternating cichs located radially outside and for
    Toally inside the cutting edges.
    In front of each knife there is a slot for chips, divided by narrow strips for overlapping at least two sections of the knife pocket for dL.

    15 chips, wherein each strip is located in a plane perpendicular to the axis of the knife shaft and is positioned radially on the edge of the knife shaft on the surface and decreasing its tip along its Width, set between two knife sections to the front edge of the knife, and adjacent to one pocket. The site with the edge located radially outside the edge is located adjacent to the apex, which is sequentially divided by a strip, which is coaxial with the radially divided edge between the outside and Inside the cutting kromkyy. The lateral side of the apex of the dividing strip, radially outside the cutting edge, is coaxial with the adjacent wall of the dividing strip. Each knife with its front face is fixed on the knife holder, which protrudes into the cavities in the front edge of the knife. The cutter holder has vertices and between them the chip removal surface extending to the bottom of the corresponding pocket. The chip removal surface has steps, respectively, radially located outside and inside. The tops of the knife holder are removable. The tops of the knife holder are provided with protruding elements located on the rear plane. Dividing strips and pockets are placed in a centrifugal wedge. The diameter of the knife shaft in front of the knife sections located radially outside is larger by the difference between the two circumferences described by the blades than the diameter of the blade shaft in front of the circumference located on the smaller blade described by the blades. The chip groove is divided into overlapping at least two knife portions of the chip pockets, which are located in a plane inclined to the axis of the blade shaft. Fig, 1. shows a diagram of the knife, top view; Fig 2, then. front view; FIG. 3 is the same, section A-A in FIG. 2; FIG. L is a diagram of the knife shaft, top view; FIG. 5 the same, side view; in fig. 6 is a diagram of the knife, knife-holder and centrifugal. wedge, top view; in fig. 7 - the same side view; in fig. 8 is a diagram of a nozheder zhatel, rear view; Fig, 9 - the same side view; FIG. 10 is a diagram of a complete blade holder assembly; FIG. in fig. 11 - this is a modified form; in fig. 12th centrifugal wedge diagram; FIG. 13 is the same, section B-B in FIG. 12. Knife v.al has a housing 1 with nests 2, each of which has a knife 3c located radially inside k and AND radially outside with 5 cutting edges, while these edges and 5 are directly adjacent to each other. The cutting edges 4 located radially inside are formed by grooves 6 selected on the front edge 7 of knife 3, the depth of grooves 6 being different and varying from one to the other end of knife 3, each of which is mounted to the axis 8 of the blade shaft housing 1 and forms an acute angle 9 with the axis 8, while the cutting edges 5 located radially outside, describe a circle 10 with a radius of 11, and cutting edges k, located radially inside, describe a circle. 12 with a radius of 13, the groove 14 for chips has dividing strips 15, which form a pocket 16. Each knife 3 is fixed to the knife holder 17 by its front edge 7, which is positioned in the grooves 6 with its projections 18. The knife holder 17 has vertices 19 installed 13, which are located in the centrifugal wedge 20 and are made, like the vertices 19, removable. Each but} kederzhatel has a surface 21 for removal of flat wood chips, while the surface 21 of the outlet is made with ledges 22 located radially on the outside and radially inside. The work of the knife shaft carried -. is as follows. When the blade housing 1 rotates 3, the cutting edges located radially inside and the cutting edges 5 located radially outside cut alternately flat wood chips that enter pockets 16, and remove the chips from the surface 21 of the discharge to a storage bin. Claim 1. Knife shaft for manufacturing laminated wood shavings containing intermittently located obliquely to the axis of the knife shaft with a variable chip angle from the leading end of the knife to the next and forming sharp oblique cutting angle knives with the axis of the knife shaft sharply oblique cutting angle which times .5, 9 are placed on the same circumference, which is characterized by the fact that, in order to improve the productivity and quality of chips, the front face of each knife is made with successively alternating along the length of the knife transverse grooves with an increasing from the leading end of the knife from minimum to maximum depth with the formation of successive alternating radially located outside and radially inside the cutting edges. 2. The blade shaft according to claim 1, lays out that in front of each knife a groove for chips is made into pockets for chips that overlap at least two knife areas, with each strip located perpendicular to the axis of the knife shaft On the surface of the knife shaft and apex decreasing in its width, it is installed between two knife sections to the front edge of the knife, and from the cutting edge located radially outside It is positioned next to a sequentially divided strip apex, which is coaxial with a radially divided edge between p located outside and inside the cutting edge about 3 "Knife shaft according to clause -2, distinguished by the fact that the cutting edge of the cutting edge facing radially outside the strips are coaxial with the adjacent wall of the dividing strip. k.
