support seat

70 and 60 of wheel seats and have one to compress spring 76, compression spring 76 two ends have respectively paste be butted on wheel seat 60 and support seat 70 shore sheet 771,772, to keep the steady of compression spring 76 starts, support seat 70 central authorities in two guide holes 72 are formed with a screw 73 in addition again, screw 73 can be taken turns 78 spiral shells for an adjustment that is hubbed at pedestal 51 axle beds 53 and be established, but and adjust and take turns the thread segment 79 of 78 tool spiral shells through aforementioned screw 73, adjust 70 relative pedestal 51 displacements of wheel 78 starts support seat but make, moreover support seat 70 is provided with an index sheet 74, this index sheet 74 is positioned at the place ahead of aforementioned wheel seat 60 scale plates 65, supply to point out to support the power of shoring of

seat

70 and 60 compressions of wheel seat spring 76, and convert the degree of tightness pulling force of saw blade 40 to.

And collocation Fig. 6 and Fig. 7 are shown, 80 on axle sleeve is formed with the pivot portion 81 of corresponding wheel seat 60 fixed blocks 63, be formed with the pivot hole 82 of wearing pivot in the pivot portion 81 for hinged arm 64, axle sleeve 80 is formed with a top 83 respectively in 82 both sides, relative pivot hole again, the central shaft hole of axle sleeve 80 is provided with a wheel shaft 85 again, these wheel shaft 85 surfaces are formed with the side grain 850 that can supply the packing bolt to press, and wheel shaft 85 passes the terminal of axle sleeve 80 and can pull for a locknut 851 locks, moreover wheel shaft 85 front ends are pivoted with a pivoted housing 86, it can be pulled for wheel body 31 locks of aforementioned driven wheels 30, moreover pedestal 51 and wheel seat 60 are provided with the swivel nut 87 of two corresponding axle sleeves, 80 tops 83, two swivel nuts, 87 spiral shells are provided with the adjusting lever 88 of shoring this top 83 respectively, and on each adjusting lever 88 and have one can be corresponding the nut 89 of swivel nut 87 location, for the horizontal-shift angle that changes axle sleeve 80 relative wheel seats 60;

By this, group formation one is easy to regulate and can show in real time the driven wheels pulling force adjustment structure of value of thrust.

See through above-mentioned structural design, the utility model is when practice, then be as Fig. 3, Fig. 5, what Fig. 6 and Fig. 7 disclosed, when needs are regulated the degree of tightness pulling force of saw blade 40, because the wheel body 31 of driven wheels 30 is to be locked on pulling force to adjust on the structure 50, so in operation, be to loosen the support seat 70 adjustment wheels 78 that pulling force is adjusted structure 50 earlier, and take turns 78 through this adjustment of rotation and come 70 relative wheel seat 60 displacements of start support seat, be example to desire to tighten, it is that order support seat 70 moves to wheel seat 60 1 ends, so can see through compression spring 76 synchronous pushing wheel bases 60, make wheel seat 60 progressively tensioning ring be around in the saw blade 40 of wheel body 31, and, can make wheel seat 60 location when its reaction force during greater than the pre-power of compression of compression spring 76, then continuation is close to wheel seat 60 for support seat 70, for further this saw blade 40 of tension, but and see through the particular design of index sheet 74 locking phases of support seat 70 to 65 displacements of wheel seat 60 scale plates, operating personnel can learn the degree of tightness pulling force of this saw blade 40 in real time.Otherwise transfer pine as desire, it then is aforementioned manner, rotate and adjust wheel 78 order support seats 70 away from wheel seat 60, when support seat 70 reaches the pre-power of answer of compression spring 76, then because support seat 70 is to utilize fastener 753 to combine with the guide pillar 75 that is locked on wheel seat 60, so can drive wheel seat 60 synchronously moves to active wheels 20, and the spacing of dwindling 20,30 of driving and driven wheels further is available for changing this saw blade 40.

Again when the wheel body 31 of driven wheels 30 because of long-term pulling force or deformation relatively the wheel body 21 of active wheels 20 be the deflection shape, and when having influence on saw blade 40 running smooth, then be two adjusting levers, 88 nuts 89 that loosen axle sleeve 80, and regulate this two adjusting lever 88 in regular turn, with utilize two adjusting levers 88 shore top, axle sleeve 80 both sides 83 before, back position, to change the deviation angle of driven wheels 30 wheel bodys 31, and after the adjustment of finishing wheel body 31 deviation angles, then lock the nut 89 on the adjusting lever 88 once more, so can guarantee the smoothness of saw blade 40 runnings, to promote cutting-rate.

By this, be appreciated that the utility model is that the splendid novel practical of an intention is novel, except the existing problem that is faced of effective solution, more significantly promote effect, and in identical technical field, do not see identical or approximate product utility model or public use, the enhancement that has effect simultaneously so the utility model has met the important document of novel patent about " novelty " and " progressive ", is the utility model patent of in accordance with the law filing an application.
