Abstract

The utility model provides the knife edge adjusting device of a rotary trunk-layer log stripping machine without clamper. The utility model comprises two pairs of eccentric camshafts with different eccentricity degree, two pairs of bearing seat, racks and rack brackets. The eccentric camshaft with larger eccentricity degree is fixedly connected with single roll shaft seat through a bearing seat so as to adjust the initial clearance between the single roll shaft and the knife edge. The eccentric camshaft which is provided with a smaller eccentricity degree is arranged at the offside and is fixedly connected with the knife rest of the rotary cutter through the bearing seat. Direct rotary cutting is realized through an eccenter. The utility model has the advantages of rational and simple structure and the thicknesses and the surface of the thin plate of rotary cutting are even and smooth. The utility model can be applied in various single roll shaft rotary cutting.

Description

The edge of a knife adjusting device of no axis rounding machine

Technical field

The utility model relates to and a kind of rounding is become the adjusting device of the no axis rounding machine of thin plate, relates to the edge of a knife adjusting device of the no axis rounding of this kind machine specifically.

Background technology

There is the phenomenon of became uneven in the wooden thin plate that existing rotary trunk-layer stripping machine without clamper rotary-cut goes out, and is even in order to make gauge of sheet, and present rotary trunk-layer stripping machine without clamper all adopts decompression or deceleration feed arrangement to control; Adopt decompressor, because the bad control of pressure, if pressure is too small, peeler can't be worked; Adopt deceleration device, the also bad control of feed speed if feed speed is too slow, has also reduced productivity ratio, therefore, adopts decompression or deceleration device to control lamella thickness, and effect is not very desirable.

Summary of the invention

The purpose of this utility model is to be to provide a kind of mechanical edge of a knife adjusting device, by the effect of this device, makes directly peeler log of no axis rounding machine, and the lamella thickness of back-out is even, and smooth surface is enhanced productivity.

A kind of technical scheme of the present utility model is as follows: a kind of edge of a knife adjusting device that does not have axis rounding machine, this device comprises two pairs of eccentric cam shafts 1,2, a pair of supporting base 3, a pair of supporting base 4, a pair of tooth bar and a pair of tooth bar support, wherein: the eccentric cam offset of eccentric cam shaft 1 is big than the eccentric cam offset of eccentric cam shaft 2; Eccentric cam shaft 1 is installed on the supporting base 3 and turns, and a pair of supporting base 3 is separately fixed at single roll shaft mounting both sides of peeler, and parallel with single roll shaft; Be connected with connecting axle by coupling band between a pair of eccentric cam shaft 1; On supporting base 3, be provided with the guiding mechanism of eccentric cam shaft 1, be provided with offset in the outside of eccentric cam shaft 1 and regulate the position; Eccentric cam shaft 2 is positioned at eccentric cam shaft 1 with laterally, and eccentric cam shaft 2 is installed on the supporting base 4 and turns; A pair of supporting base 4 is separately fixed at the knife rest both sides of peeler; The axial outside at eccentric cam shaft 2 is provided with gear, this wheel and rack engagement, and tooth bar is fixed on the tooth bar support, and the tooth bar support is fixed on the peeler base; Connect by yoke plate between the eccentric wheel of eccentric cam shaft 1 and eccentric cam shaft 2.

Another kind of technical scheme of the present utility model is can between a pair of eccentric cam shaft 2 connecting axle be set on the technique scheme basis, the convenient installation and the reinforcement integral rigidity.

The utility model can also be realized like this: guiding mechanism is made up of limited block and clamping screw.

The offset of eccentric cam shaft 1 is with 4～6mm in the utility model, and the offset of eccentric cam shaft 2 is good with 1.8～2.2mm.

The utility model structural design advantages of simple, make lamella thickness that rotary-cut comes out evenly, smooth surface, be a kind of desirable adjustment knife edge device.

Among the figure: eccentric cam shaft 1, eccentric cam shaft 2, supporting base 3, supporting base 4, tooth bar 5, tooth bar support 6, coupling band 7, connecting axle 8, guiding mechanism 9, limited block 91, clamping screw 92, offset are regulated position 10, gear 11, yoke plate 12, connecting axle 13, single roll shaft mounting 21, single roll shaft 22, knife rest 23, rotary-cut cutter 24, slide 25, traveller 26

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described in further detail.

As shown in Figure 1 to Figure 3, the edge of a knife adjusting device of no axis rounding machine, this device comprises two pairs of eccentric cam shafts 1,2, a pair of supporting base 3, a pair of supporting base 4, a pair of tooth bar 5 and a pair of tooth bar support 6, the eccentric cam offset of eccentric cam shaft 1 is 5mm, and the eccentric cam offset of eccentric cam shaft 2 is 2mm; Eccentric cam shaft 1 is installed on the rolling bearing of supporting base 3, and a pair of supporting base 3 is separately fixed at single roll shaft mounting 21 both sides of peeler, and parallel with single roll shaft 22; Be connected with connecting axle 8 by coupling band 7 between a pair of eccentric cam shaft 1; Be provided with the guiding mechanism 9 of eccentric cam shaft 1 on supporting base 3, this guiding mechanism 9 is made up of limited block 91 and clamping screw 92.Be provided with offset in the outside of eccentric cam shaft 1 and regulate position 10, be outer-hexagonal shape wrench position; Eccentric cam shaft 2 is positioned at eccentric cam shaft 1 with laterally, and eccentric cam shaft 2 is installed on the rolling bearing of supporting base 4; A pair of supporting base 4 is separately fixed at knife rest 23 both sides of peeler; The axial outside at eccentric cam shaft 2 is provided with gear 11, this gear 11 and tooth bar 5 engagements, and tooth bar 5 is fixed on the tooth bar support 6, and tooth bar support 6 is fixed on the peeler base; Between a pair of eccentric cam shaft 2, be provided with connecting axle 13.Connect by yoke plate 12 between the eccentric wheel of eccentric cam shaft 1 and eccentric cam shaft 2.Between yoke plate 12 and eccentric wheel, be provided with rolling bearing.

When the utility model is specifically practical, because of the single roll shaft mounting 21 on the peeler links to each other with slide 25, slide 25 can at slip, traveller 26 on the traveller 26 and rotary-cut cutter 24 be fixed on the knife rest 23, single roll shaft mounting 21 can slide by relative knife rest 23.Thereby before the peeler log, according to want the rotary-cut gauge of sheet, unclamp spacing clamping screw 92, with spanner transfer two eccentric cam shafts, 1 hex head end, because of the offset of eccentric cam shaft 1 greater than eccentric cam shaft 2, tooth bar 5 maintain static, rotate eccentric cam shaft 1, eccentric cam shaft 1 will drive supporting base 3 motions, supporting base 3 drive single roll shaft mounting 21 motion promotions or spur single roll shaft 22 reach required edge of a knife width, mix up after lock plunger 92.Thereby during withdrawing, knife rest 23 in the process that retreats, tooth bar 5 gear 11 that maintains static, be meshed with it be forced to rotate drive eccentric cam shaft 2 average rates rotate, because eccentric effect, single roll shaft mounting 21 and single roll shaft 22 relative rotary-cut cuttves 24 pull back, edge of a knife width evenly increases gradually so that log opening when beginning rotary-cut is removed the peel; After the peeling, thus round log in feed rotary-cut process, owing to the backward rotation of eccentric cam shaft 2 promote single roll shaft 22 slowly move forward, reduce equably gradually edge of a knife width has been realized direct peeler log and the lamella thickness that screws out evenly, the more smooth purpose in surface.
