Backstand 51, this backstand 51 is fixed in frame 7;
Support axle 52, one end of this support axle 52 and backstand 51 pivot joint;
Swing span 53, the side of this swing span 53 is fixed with supporting axle 52, and support axle 52 can be driven to rotate;
Roller bearing 54, this roller bearing 54 is articulated in the opposite side of swing span 53, and the axial direction of this roller bearing 54 is parallel with the axial direction supporting axle 52;
Regulating wheel 3, the axis hole socket at this regulating wheel 3 center is fixed on roller bearing 54, and the outer peripheral face of this regulating wheel 3 engages with the inner toothed surface of toothed wedge belt 4;
Hold-down mechanism, this hold-down mechanism elasticity is adjustably connected between swing span 53 and backstand 51, for regulating the deflection angle of this swing span 53;
Hold-down mechanism compresses swing span 53 after regulating, and make the side of swing span 53 drive support axle 52 to rotate, the opposite side of this swing span 53 drives roller bearing 54 and regulating wheel 3 to deflect, and makes the outer peripheral face of regulating wheel 3 hold out against the inner toothed surface of toothed wedge belt 4 this toothed wedge belt 4 of tensioning.
Toothed wedge belt 4 is engaged with each running roller by inner toothed surface and the outer flank of tooth, as it is shown in figure 1, regulating wheel 3 left shift then can make toothed wedge belt 4 tensioning. Regulating wheel 3 shown in Fig. 1 is fixed on swing span 53, and swing span 53 is connected with backstand 51 by supporting axle 52, and swing span 53 can do around axle motion around supporting axle 52, and left shift is tensioning toothed wedge belt 4 then, offsets to the right then lax toothed wedge belt 4. The thrust of toothed wedge belt 4 is depended on the hold-down mechanism elastic force to it by regulating wheel 3, and hold-down mechanism is to the thrust of 53 1 rotations counterclockwise of swing span, thus driving regulating wheel 3 to offset to the left. In actual use; flour mill is when starting; toothed wedge belt 4 can bear certain pulling force moment; owing to regulating wheel 3 is not rigidity tensioning; regulating wheel 3 can be extruded in the moment of toothed wedge belt 4 stress and make it offset to the right; make hold-down mechanism be elastically compressed, thus serving the effect alleviating toothed wedge belt 4 tension force, protecting toothed wedge belt 4 and will not be stretched the excessive and brief life-span.
As it is shown in figure 1, a kind of concrete structure of hold-down mechanism is it may be that hold-down mechanism includes:

Adjusting nut 58, is socketed in pull bar 55 and forms one end of screw thread, the bottom apical grafting of this adjusting nut 58 and spring 57.
In the hold-down mechanism of this kind of structure, elastic force is that the adjusting nut 58 being socketed on pull bar 55 by spring 57 bottom controls, rotating adjusting nut 58 so that it is move up, then spring 57 is compressed, and swing span 53 is upwards withstood on the top of spring 57; When elastic force is excessive, it is possible to rotating adjusting nut 58 makes it move down, discharge certain space, make swing span 53 stress in the counterclockwise direction reduce, thus reducing the regulating wheel 3 tensile force to toothed wedge belt 4. The benefit of application spring 57 is, when the unexpected tension force of toothed wedge belt 4 increases, spring 57 can be compressed according to stress size, and then toothed wedge belt 4 is served protective effect.
Pivoting is done, in order to make spring 57 better swing span 53 be applied elastic force, it is necessary to certain deflection occurs in the direction that spring 57 also rotates with swing span 53 owing to being around support axle 52 after swing span 53 stress. Therefore, in one embodiment of the present of invention, it is possible to make pull bar 55 by connecting axle 56 and backstand 51 pivot joint. As shown in Figure 1, after swing span 53 deflects to the left, spring 57 top move upward, the deflection of certain angle is there is around connection axle 56 in spring 57 with pull bar 55, its top has almost no change for the force direction of swing span 53 support body, make swing span 53 stress will not reduce due to deflection angle, make the tensile force that toothed wedge belt 4 is applied by regulating wheel 3 more stable.
Further, as it is shown in figure 1, in order to hold out against swing span 53 better, be provided with the first packing ring 59 between top and the swing span 53 of spring 57, be provided with the second packing ring 6 between spring 57 and adjusting nut 58.
