The specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, shown in Figure 2, spring pressure structure in the reel cage, comprise: rocking arm and base 1, be hinged with handle 2 and rocking arm 3 on the rocking arm and base 1, roller claw 4 is installed in the downside of rocking arm 3 by pressure-applying unit, the structure of described pressure-applying unit is: be installed with pressure foot 5 on rocking arm 3, be provided with installation cavity 51 in the pressure foot 5, be movably set with leather roller seat 6 in the installation cavity 51, the lower end of leather roller seat 6 is provided with roller claw 4, between the top of leather roller seat 6 and installation cavity 51, be provided with spring 7, pressure foot 5 is provided with the regulator of energy regulating spring 7 pressure, its structure is: be provided with the pressure regulating axis 8 that can rotate in the upper end of pressure foot 5, pressure regulating axis 8 is provided with four pressure regulation faces, be respectively the first pressure regulation face 81, the second pressure regulation face 82, the 3rd pressure regulation face 83 and the 4th pressure regulation face 84, each pressure regulation face is all unequal to the distance of the axial line of pressure regulating axis 8, and pressure regulation face contacts with the upper padding plate 9 that is arranged on spring 7 tops.Be provided with stopping means between pressure foot 5 and leather roller seat 6, its structure is: the lateral wall of leather roller seat 6 is provided with stopper slot 61, and pressure foot 5 is provided with stop screw 10, and stop screw 10 extend in the stopper slot 61.Bottom at leather roller seat 6 also is provided with micrometer adjusting screw 11, and micrometer adjusting screw 11 contacts with the lower bolster 12 that is arranged on spring 7 bottoms.
During work, earlier in the roller claw 4 of leather roller seat 6 lower ends, load onto roller 13, then handle on the rocking arm and base 12 and rocking arm 3 are closed, roller 13 is pressed on the roller 14 like this, spring 7 compressions in the installation cavity 51 in the pressure foot 5 at this moment, the elastic force that spring 7 distortion produce vertically acts on the roller 13 by lower bolster 12, and roller 13 acts directly on pressure on the roller 14.Because the reaction force of 14 pairs of rollers 13 of roller, fixedly the leather roller seat 6 of roller 3 can move up along the inwall of installation cavity 51 in moment, this moment, stop screw 10 blocked the stopper slot 61 on the leather roller seat 6, play the effect that restriction leather roller seat 6 moves up always, also can play the effect that restricted guidance leather roller seat 6 moves down always simultaneously.On pressure regulating axis 8, be provided with four pressure regulation faces, because each pressure regulation face is all unequal to the distance of the axial line of pressure regulating axis 8, thus adjust the deflection that can change spring 7 with upper padding plate 9 contacted pressure regulation faces, thus the pressure of 13 pairs of rollers 14 of roller changed.As shown in Figure 3, Figure 4, the first pressure regulation face 81 to the distance of the axial line of pressure regulating axis 8 is H2, the second pressure regulation face 82 to the distance of the axial line of pressure regulating axis 8 is H3, the 3rd pressure regulation face 83 to the distance of the axial line of pressure regulating axis 8 is H4, the 4th pressure regulation face 84 to the distance of the axial line of pressure regulating axis 8 is H1, four pressure regulation faces are the fourth gear pressure regulation, rotate pressure regulating axis 8 and select corresponding pressure regulation face, thereby select the roller pressure of corresponding gear.Bottom at leather roller seat 6 also is provided with micrometer adjusting screw 11, being screwed into of micrometer adjusting screw 11 back-out can minor alteration spring 7 deflection, thereby carry out the fine setting of pressure.Micrometer adjusting screw 11 can be adjusted behind the pressure regulation face of choosing again.
Its structure of the pressure structure of Spring cradle of the present invention is very simple, overcome the various shortcoming of part in the pressure lever type pressing mechanism of traditional reel cage, roller is given in the vertical effect of the elastic force of spring, improved the operating efficiency of spring, reduced the fatigue deformation of spring, and the adjustment that pressure regulating axis and micrometer adjusting screw can be realized a plurality of gear active forces is set in pressure foot, pressure is adjusted very convenient, can satisfy the needs of the different yarns of weaving.
