Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
In order to obtain smooth-going constant self adaptation pinch roller operating mode, improve product design and production efficiency, extend the service life of self adaptation pinch roller, the utility model comprises wheel pressing shaft 3 and is positioned at end, described wheel pressing shaft 3 one end and the pivot shaft 10 of coaxial distribution; On pivot shaft 10, cover has main support 4; Described pivot shaft 10 also overlaps flexible supplemental support 2; Arrange in the outer ring of described pivot shaft 10 and carry out go back to positive pinch roller outer ring 1 by elasticity supplemental support 2.
Particularly, the front end of wheel pressing shaft 3 arranges pivot shaft 10, and the external diameter of described pivot shaft 10 is less than the external diameter of wheel pressing shaft 3 rearward end, and elasticity supplemental support 2 and main support 4 are all enclosed within the pivot shaft 10 of wheel pressing shaft 3.Pinch roller outer ring 1 is arranged on pivot shaft 10 and also can relatively rotates, the elastic-restoring force provided by elasticity supplemental support 2 of beating when pinch roller outer ring 1 works just carries out back, make the outside face of pinch roller outer ring 1 to the maintenance self adaptation on conveying roller surface, product design and production efficiency can be improve.
Carry out when the yarn passed through at a high speed and tractive force produce interference adaptive pinch roller in order to elasticity supplemental support 2 pairs of pinch roller outer rings 1 can be allowed effectively just returning, pinch roller outer ring 1 can adopt different fit form between elasticity supplemental support 2, main support 4 and pivot shaft 10, specifically as shown in Figure 1, Figure 2 and shown in Fig. 3.
As shown in Figure 1, described pinch roller outer ring 1 is arranged on pivot shaft 10 by bearing 6, and the inner ring of bearing 6 contacts with main support 4, elasticity supplemental support 2, and the outer ring of bearing 6 contacts with the inwall of pinch roller outer ring 1.
Particularly, main support 4, elasticity supplemental support 2 are between bearing 6 and pivot shaft 10, bearing 6 is arranged on pivot shaft 10 by main support 4 and elasticity supplemental support 2, pinch roller outer ring 1 is directly arranged on pivot shaft 10 by bearing 6, and elasticity supplemental support 2 can in the outside of main support 4 or inner side.The inwall of pinch roller outer ring 1 is provided with inner covering 7, and the outer ring of bearing 6 contacts with inner covering 7.When the yarn passed through at a high speed or tractive force produce interference pinch roller outer ring 1, the elastic-restoring force of elasticity supplemental support 2 by pinch roller outer ring 1 being allowed just to carry out back after bearing 6 transmission, thus makes the outside face of pinch roller outer ring 1 can keep self adaptation state to conveying roller surface.
As shown in Figure 2, on described pivot shaft 10, cover has collet 8, and collet 8 is supported on pivot shaft 10 by main support 4, elasticity supplemental support 2, and pinch roller outer ring 1 utilizes bearing 6 to be arranged on collet 8, and pinch roller outer ring 1, collet 8 and wheel pressing shaft 3 coaxially distribute.
Particularly, collet 8 is enclosed within pivot shaft 10, and main support 4, elasticity supplemental support 2 are between collet 8 and pivot shaft 10, and elasticity supplemental support 2 can be positioned at outside or the inner side of main support 4, collet 8 is arranged bearing 6, pinch roller outer ring 1 utilizes bearing 6 to be arranged on collet 8.Be provided with supplemental support step 9 in described collet 8, can carry out supporting to the installation of elasticity supplemental support 2 by supplemental support step 9 and locate.
When the yarn passed through at a high speed or tractive force produce interference pinch roller outer ring 1, the elastic-restoring force of elasticity supplemental support 2 by pinch roller outer ring 1 being allowed just to carry out back after collet 8 and bearing 6 transmission, thus makes the outside face of pinch roller outer ring 1 can keep self adaptation state to conveying roller surface.
As shown in Figure 3, the end of described pivot shaft 10 is provided with wheel pressing shaft end cap 5, and the wheel pressing shaft 3 between described wheel pressing shaft end cap 5 and main support 4 is provided with elasticity supplemental support 2; Further, described elasticity supplemental support 2 is between collet 8 and wheel pressing shaft 3.
Particularly, be that the end of pivot shaft 10 arranges wheel pressing shaft end cap 5 with the difference in Fig. 2, the external diameter of wheel pressing shaft end cap 5 is greater than the external diameter of pivot shaft 10, can carry out spacing to elasticity supplemental support 2 by wheel pressing shaft end cap 5.
Further, be provided with supplemental support step 9 in described collet 8, elasticity supplemental support 2 is between supplemental support step 9 and wheel pressing shaft end cap 5.
In the present embodiment, elasticity supplemental support 2 can optional position between main support 4 and wheel pressing shaft end cap 5, and preferably, elasticity supplemental support 2 is close to wheel pressing shaft end cap 5.When elasticity supplemental support 2 is close to wheel pressing shaft end cap 5, elasticity supplemental support 2 is embedded in supplemental support step 9, between supplemental support step 9 and wheel pressing shaft end cap 5, coordinates to position with collet 8.Described elasticity supplemental support 2 is " O " type structure of integrally closed, " C " type structure split of opening or grain pattern.
Originally execute in example, after main support 4 and elasticity supplemental support 2 are set between collet 8 and wheel pressing shaft 3, when the mode of operation of the interference adaptive pinch roller outer rings 1 such as the yarn passed through at a high speed and tractive force, auxiliary elastic-support 2 forced compression, its elastic reset power provides the power of self adaptation pinch roller outer ring 1 self-aligning, there is provided during auxiliary elastic-support 2 forced compression simultaneously and overcome self adaptation pinch roller outer ring 1 and produce the damping of beating, when collet 8 can be provided to work axially, the restoring force of radial motion, obtain smooth-going with this, constant self adaptation pinch roller operating mode, improve product design and production efficiency, extend the service life of self adaptation pinch roller.
In the utility model embodiment, described collet 8 is combined by two semicircular cylinder bodies.Main support 4, elasticity supplemental support 2 also coaxially distribute with wheel pressing shaft 3.
The utility model arranges elasticity supplemental support 2 on pivot shaft 10, coordinated with main support 4 by it, the single-point support only provided by main support 4 compared to existing technology, when the mode of operation of the interference adaptive pinch rollers such as the yarn passed through at a high speed and tractive force, auxiliary elastic-support 2 forced compression, its elastic reset power provides the moment of self adaptation pinch roller outer ring 1 self-aligning, can provide during auxiliary elastic-support 2 forced compression simultaneously and overcome self adaptation pinch roller outer ring 1 and produce the damping of beating, obtain smooth-going with this, constant self adaptation pinch roller operating mode, improve product design and production efficiency, extend the service life of self adaptation pinch roller.
