Abstract
The spring rocking arm with adjustable pressure in the middle zone and back zone has middle pressurizing spring and back pressurizing spring with pressure regulating unit each. Each of the pressure regulating unit comprises a pressure regulating seat and a pressure regulating rotation seat, the pressure regulating seat has three end cam blocks in the bottom and the pressure regulating rotation seat has locating shaft steps with regulating hole and end cam surfaces corresponding to the end cam blocks in the pressure regulating seat. Regulating the pressure regulating rotation seat with one quadrangular spanner can move the pressure regulating rotation seat axially to reach the aim of regulating the height of the spring and regulating the pressure.
Description
Technical field:
The present invention relates to the Spring cradle that a kind of cotton spinning frame is used, relate in particular to the multi-stage pressure regulating Spring cradle.
Background technology:
All contain drafting system in cotton spinning frame, its pressurization form is the third gear gerotor type, and it is to realize pressurization, release of pressure by Spring cradle, to satisfy spinning requirement.With regard to YJ2-142 series cotton spinning spun yarn reel cage, three pressurised zones before, during and after being divided into, wherein the force value of exerting pressure of preceding pressurised zone is 100,140,180 newton/two ingot third gear, in the force value of exerting pressure of pressurised zone be one grade of 100 newton/two ingots, the back pressurised zone force value of exerting pressure is one grade of 140 newton/two ingots.In spinning process, require pressure stability, continue.Existing spun yarn reel cage satisfies spinning requirement substantially on Pressure control, along with development of times, people are more and more higher to the requirement of textiles, and fabric is also tighter to technological requirement.In order to adapt to up-to-date textile technology requirement, the cotton spinning spun yarn reel cage must possess following function:
1. three pressurised zones are exerted pressure and will be aspired for stability;
2. the adjustable size of exerting pressure of district, back zone pressurised zone in;
Existing cotton spinning spun yarn reel cage all can't satisfy above-mentioned requirement at second, and textile enterprise presses for this multi-stage pressure regulating Spring cradle.
Summary of the invention:
Goal of the invention of the present invention provide a kind of in district, the back zone adjustable spring reel cage of exerting pressure.
District, the back zone adjustable spring reel cage of exerting pressure in a kind of, pressor areas and back pressor areas in comprising, it is characterized in that: the upper end in middle pressing spring, back pressing spring is equipped with regulator, described regulator is made up of pressure regulating seat and pressure regulation rotation seat, the end face of pressure regulating seat acts on the inner top surface of reel cage body, the lower end of pressure regulation rotation seat acts on the upper end of spring, is provided with between pressure regulating seat and pressure regulation rotation seat and can produces axially movable edge cam structure.
Be provided with between described pressure regulating seat and the pressure regulation rotation seat and can produce axially movable edge cam structure and be: equally be provided with three edge cam pieces in the bottom surface of pressure regulating seat, and three edge cam pieces are distributed in the periphery edge of circular locating hole; The upper end of pressure regulation rotation seat be provided with the pressure regulating seat bottom surface on the corresponding edge cam profile of three edge cam pieces.
Because regulator has been set up in the upper end in middle pressing spring, back pressing spring, pressure regulating seat contacts with reel cage body inner top surface, the lower surface of pressure regulation rotation seat contacts with the spring upper end, be provided with between pressure regulating seat and the pressure regulation rotation seat and can produce axially movable edge cam structure, as long as rotate the pressure regulation rotation seat, the pressure regulation rotation seat will produce axial displacement, thereby changes the spring height, reaches the purpose of regulating pressure.

The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated:
District, the back zone adjustable spring reel cage of exerting pressure is the improvement of making on the basis of existing YJ2-142 series Spring cradle in of the present invention, continued to use retaining mechanism, the pressurised zone of YJ2-142 series Spring cradle, centering district, back zone spring pressing structure have carried out the adjustability improvement.Upper end in middle pressing spring 3, back pressing spring 4 is equipped with regulator 13, it is made up of pressure regulating seat 14 and pressure regulation rotation seat 15, the end face of pressure regulating seat 14 is the plane, offered a circular locating hole 141 on it, equally be provided with three edge cam pieces 142 in the bottom surface of pressure regulating seat 14, and three edge cam pieces 142 are distributed in the periphery edge of circular locating hole 141; The lower end of pressure regulation rotation seat 15 is provided with the spring base core, the upper end of pressure regulation rotation seat 15 be provided with the band adjustment hole positioning step 151 and with pressure regulating seat 14 bottom surfaces on three corresponding edge cam profiles 153 of edge cam formation of lots face.
