Technical field
The present invention relates to the reel cage on frame, particularly relate to the spring-weighted structure in a kind of reel cage.
Background technology
Drawing and pressuring device in frame is commonly called as reel cage, its structure mainly comprises: rocking arm and base, rocking arm and base is hinged with handle and reel cage arm, the downside of reel cage arm is provided with roller pawl, generally include front leather roller pawl, medium rubber roller pawl, rear roller pawl, each roller pawl is arranged on the lower end of respective pressure-applying unit respectively, and pressure-applying unit is installed in the downside of reel cage arm.Pressure-applying unit conventional at present comprises spring pressurization and Pneumatic Pressure two kinds of forms, wherein spring loaded structure is: roller pawl is arranged on the lower end of lever depression bar, depression bar is movably arranged on rocking arm by bearing pin, spring is arranged between depression bar and reel cage arm, pressure is passed to roller pawl and roller by depression bar by spring, carrys out the pressure of regulating spring to roller by the installation site between adjustment spring and depression bar.During work, rocking arm and base is fixedly mounted on the boss rod in frame, and in each roller pawl the good corresponding roller of clamping, downward pressing handle and reel cage arm, under the effect of respective pressure-applying unit, roller is pressed on each self-corresponding roller with certain pressure, thus realizes spinning function.
The shortcoming of above-mentioned traditional spring-weighted structure is: pressure adjusting extremely bothers, and this lever-type pressure structure requires that the deformation of spring is large, and spring fatiguability, need change spring in time, production cost is higher.
Summary of the invention
The invention provides the spring-weighted structure in the reel cage that a kind of pressure adjusting is convenient, spring deformation is less.
For realizing above-mentioned spring-weighted structure, the present invention by the following technical solutions:
Spring-weighted structure in a kind of reel cage, comprise rocking arm and base, rocking arm and base is hinged with handle and reel cage arm, the downside of reel cage arm is provided with roller pawl by pressure-applying unit, described pressure-applying unit comprises: pressure foot, leather roller seat, pressing spring, pressurizing nut, described pressure foot is fixedly installed on described reel cage arm, pressure foot hollow is provided with pressurizing chamber, described leather roller seat is movably set in described pressurizing chamber, described roller pawl is arranged at the lower end of described skin rod seat, described pressurizing nut to be arranged in described pressurizing chamber and to be spirally connected with described pressure foot, described pressing spring is arranged between described pressurizing nut and skin rod seat.
Wherein, the stopping means making the spacing movement of skin rod seat is also provided with between described pressure foot and skin rod seat.
Wherein, described stopping means is stop screw, the arranged outside limited location groove of described skin rod seat, and described stop screw stretches in stopper slot through pressure foot.
Wherein, the bottom of described skin rod seat is also provided with micrometer adjusting screw, and described micrometer adjusting screw contacts with the lower bolster being arranged on spring bottom end.
Wherein, the pitch of screw thread that described pressurizing nut and pressure foot are spirally connected is 0.3-0.5mm.
Beneficial effect of the present invention is: by arranging pressure spring and look nut in pressure foot, applies pressure by pressure spring Vertical dimension roller, and overall pressure adjusting structure is very simple, to pressure uniform and the dispersion of pressure spring, reduces spring deformation.

Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Fig. 1 and Fig. 2 is the generalized section of the spring-weighted structure in the generalized section of the reel cage of the spring-weighted structure installed in the present invention a kind of reel cage and a kind of reel cage of the present invention respectively, as shown in the figure, spring-weighted structure in this reel cage, comprise rocking arm and base 1, rocking arm and base 1 is hinged with handle 2 and reel cage arm 3, the downside of reel cage arm 3 is provided with roller pawl 14 by pressure-applying unit, it is characterized in that, described pressure-applying unit comprises: pressure foot 6, leather roller seat 7, pressing spring 5, pressurizing nut 4, described pressure foot 6 is fixedly installed on described reel cage arm 3, pressure foot 6 hollow is provided with pressurizing chamber 61, described leather roller seat 7 is movably set in described pressurizing chamber 61, described roller pawl 14 is arranged at the lower end of described skin rod seat 7, described pressurizing nut 4 to be arranged in described pressurizing chamber 61 and to be spirally connected with described pressure foot 6, described pressing spring 5 is arranged between described pressurizing nut 4 and skin rod seat 7.The stopping means making the spacing movement of skin rod seat 7 is also provided with between described pressure foot 6 and skin rod seat 7.Described stopping means is stop screw 72, the arranged outside limited location groove 71 of described skin rod seat 7, and described stop screw 72 stretches in stopper slot 71 through pressure foot 6.The bottom of described skin rod seat 7 is also provided with micrometer adjusting screw 13, and described micrometer adjusting screw 13 contacts with the lower bolster 15 being arranged on spring 5 bottom.The pitch of the screw thread that described pressurizing nut 4 is spirally connected with pressure foot 6 is 0.3-0.5mm.
During work, first in the roller pawl 14 of leather roller seat 7 lower end, load onto roller 12, then the handle 2 on rocking arm and base 1 is closed with reel cage arm 3, such roller 12 is pressed on roller 11, pressing spring 5 compression now in pressure foot 6 in pressurizing chamber 61, pressing spring 5 is out of shape the elastic force produced and is vertically acted on roller 12 by lower bolster 15, and pressure acts directly on roller 11 by roller 12.Due to the reaction force of roller 11 pairs of rollers 12, the leather roller seat 7 of fixing roller 12 can move up along the inwall of pressurizing chamber 61 instantaneously, now stop screw 72 blocks the stopper slot 71 on leather roller seat 7, play the effect that restriction leather roller seat 7 moves up always, also can play the effect that restricted guidance leather roller seat 7 moves down always simultaneously.When needs spin to raw material such as cotton, chemical fibre, silks, can control to produce required different pressures between roller 12 and roller 11 by regulating pressurizing nut 4, realize the application of the wide region of frame, simultaneously, in order to make the pressure accurately easily control further of generation, the pitch of the screw thread that described pressurizing nut 4 is spirally connected with pressure foot 6 is 0.3-0.5mm, and the advance distance rotating pressurizing nut 4 is each time more meticulous, and micrometer adjusting screw 11 can adjust further.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, any people being familiar with this technology is in the technical scope disclosed by the present invention; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
