If do not adjusted, between rider roller 1 and wavers 2, because rider roller 1 runs up for a long time, the surface of rider roller 1 produces wearing and tearing and produces gap between rider roller 1 and wavers 2 after being out of shape, have influence on the precision of chromatography pressure. adjustment, can at substantial man power and material.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of rider roller pressure automatic adjusting device is provided, effectively ensures the orientation distance between rider roller and wavers, maintainance set coining power, avoid the trouble of manual adjustments, improve quality and the quality of printing.
A kind of technical scheme realizing above-mentioned purpose is: a kind of rider roller pressure automatic adjusting device, comprise wavers, wallboard and rider roller, described wavers is fixed on described wallboard, the two ends of described wavers are respectively equipped with jib, described rider roller and described wavers be arranged in parallel, and the two ends of described rider roller are provided with spindle nose;
The spindle nose correspondence at described rider roller two ends is fixed by a spring reverse motion and a described jib, each described jib is provided with one for installing the installation through hole of described spring reverse motion, and described spring reverse motion comprises connecting axle, axle sleeve and spring;
Described connecting axle runs through described installation through hole, and the spindle nose of described rider roller and described jib are fixed by the bottom of described connecting axle, described axle sleeve is fixed at the radial outside of described connecting axle and described installation through hole, described spring is socketed at described axle sleeve radially inner side and described connecting axle, and the two ends up and down of described spring are respectively equipped with stopping means.
Further, the bottom of described connecting axle is provided with the annular brace platform that supports described spring, and described axle sleeve radially inner side is also provided with the lining ring be socketed with described connecting axle, and described lining ring is connected with the top of described spring.
Further, the top of described connecting axle is higher than the top of described axle sleeve.And the top of described connecting axle is socketed with alignment pin.
Further, described axle sleeve is fixed by external screw thread and described installation through hole.
Have employed the technical scheme of a kind of rider roller pressure automatic adjusting device of the present utility model, fixed by spring reverse motion by rider roller and jib; Described spring reverse motion comprises connecting axle, axle sleeve and spring; Described connecting axle runs through the installation through hole on jib, and the spindle nose of described rider roller and described jib are fixed by the bottom of described connecting axle, described axle sleeve is fixed at the radial outside of described connecting axle and described installation through hole, described spring is socketed at described axle sleeve radially inner side and described connecting axle, and the two ends up and down of described spring are respectively equipped with stopping means.Its technique effect is: the function utilizing spring reset, automatically, reliably can regulate the pressure between rider roller and adjacent drive wavers, avoid the cumbersome process regulated manually, not only improve chromatography precision quality, and reduce production hour loss, thus produce good productivity effect.

Detailed description of the invention
Refer to Fig. 2 and Fig. 3, inventor of the present utility model, in order to understand the technical solution of the utility model better, below by embodiment particularly, and is described in detail by reference to the accompanying drawings:
Refer to Fig. 2 and Fig. 3, a kind of rider roller pressure automatic adjusting device of the present utility model, comprises wavers 2, wallboard 3 and rider roller 1.Wavers 2 is fixed on wallboard 3, and the two ends of wavers 2 are respectively equipped with jib 4, and rider roller 1 and wavers 2 be arranged in parallel, and the two ends of rider roller 1 are provided with spindle nose 11.
Two spindle nose 11 correspondences that the two ends correspondence of rider roller 1 is arranged are fixed by a spring reverse motion 5 and a jib 4, each jib 4 is provided with an installation through hole 41 for mounting spring resetting means 5, and spring reverse motion 5 comprises connecting axle 51, axle sleeve 52 and spring 53.
Wherein, connecting axle 51 runs through installs through hole 41, and axle sleeve 52 is fixed by the external screw thread be positioned on axle sleeve 52 excircle with installation through hole 41 at the radial outside of connecting axle 51, and makes the two ends up and down of connecting axle 51 stretch out axle sleeve 52 respectively.Spring 53 is socketed at axle sleeve 52 radially inner side and connecting axle 51.Wherein, the lower end of connecting axle 51 is provided with an annular brace platform 56 for support spring 53, and annular brace platform 56 is for being positioned at the stopping means of the lower end of spring 53.The bottom of annular brace platform 56, namely the spindle nose 1 of rider roller 1 is fixed with jib 4 by the bottom of connecting axle 51.The footpath on axle sleeve 52 top is inwardly also provided with the lining ring 54 be socketed with connecting axle 51, and lining ring 54 is connected with the top of spring 53, for being positioned at the stopping means of spring 53 upper end.Such spring 53 again can be rejected after being compressed by connecting axle 51.
Meanwhile, the top of connecting axle 51 is also socketed with alignment pin 55.The effect of alignment pin 55 is the initial positions regulating connecting axle 51 movement, the displacement that connecting axle 51 rebounds by restraining spring 53.
By above-mentioned design, rider roller 1, when rider roller 1 is shifted due to pressure change, is retracted original position by the anti-compression stress of spring 53, to ensure the original pressure between rider roller 1 and wavers 2, is enhanced productivity by spring reverse motion 5.And the prior art of pressure between traditional employing manual adjustments rider roller 1 and wavers 2, spring reverse motion 5 in the utility model can keep the original position of rider roller 1, thus keep rider roller 1 and the roll body surface pressing of wavers 2, improve positioning precision, save regulating time.
A kind of rider roller pressure automatic adjusting device of the present utility model effectively can ensure the orientation distance between rider roller 1 and wavers 2, and maintainance set coining power, avoids the trouble of manual adjustments, improves quality and the quality of printing.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
