Technical field
The utility model relates to a kind of pressue device that changes testing agency for feeding sliver thickness.
Background technology
In the production of yarn product, mixing in doubling step is an important link.Common drawing frame, by 4～8 one ribbons and close and drawing-off, makes ripe of output to become more even.Because the drafting multiple of drafting system need to arrange according to technique, and fix.So, export the uniformity of ripe, depend on the uniformity and the amalgamation that feed ribbon completely.
Along with the raising that people require yarn qualities, the uniformity of ripe of only producing by amalgamation, cannot meet the production requirement of high evenness yarn.This just needs autoleveller draw frame to complete this work.
The operation principle of autoleveller draw frame is: the ribbon total amount to feeding drawing frame is measured, again the ribbon through measuring is transported to drafting system, the drafting multiple of drafting system changes in real time according to the total amount that ribbon is measured, make ripe of output more even.
In the prior art, the measurement to feeding ribbon total amount, is generally that the thickness that feeds ribbon by measurement is realized.Measuring process is: feeding ribbon is introduced to the fixing detection roller of a pair of height, at this, to detecting between roller, apply a stable pressure.Like this, be compressed in the thickness that detects the ribbon between roller, just represented the total amount of feeding ribbon.
At present, the device that detection roller is exerted pressure mainly contains two kinds of forms, and a kind of is spring pressurization form, and another kind is Pneumatic Pressure form.All there are some shortcomings in these two kinds of pressurization forms.Pneumatic Pressure form is realized and being pressurizeed to detecting roller by cylinder.At cylinder, complete detecting after the pressurization of roller, due to the existence of stiction between cylinder piston and cylinder body, the sensitivity of checkout gear is affected.That is, the variation of ribbon feeding total amount, while being not enough to overcome between cylinder piston and cylinder body stiction, checkout gear will be failure to actuate, and the variable quantity of its ribbon gross thickness can not be reflected.And spring pressurization form is although sensitivity is fine, very large to the variation of detected ribbon applied pressure.When the Thickness Ratio of ribbon in detection roller is thinner, spring is smaller to detecting roller applied pressure; When the Thickness Ratio of ribbon in detection roller is thicker, spring is larger to detecting roller applied pressure.That is, due to the pressure of spring pressurization form change greatly, unstable to detection roller applied pressure.So the ribbon varied in thickness measuring can not accurately reflect the variation of feeding ribbon total amount.When machine is changed the different fiber of processing compressibility, if use the checkout gear of spring pressurization form, need to readjust the active length of spring.This process is very loaded down with trivial details, and is difficult to guarantee the precision of adjustment.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of and can feed ribbon varied in thickness mechanism to Accurate Measurement, applies steady pressure, and be quick on the draw, pressue device easy to adjust.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises frame, in frame, be provided with fixedly roller and the dance roller with detection swing arm, the upper end of detecting swing arm is hinged with frame, it is characterized in that: hingedly in described frame be provided with the pressurization lever identical with described detection swing arm direction, between the middle part of the lower end of described detection swing arm and pressurization lever, by horizontal pressing spring, be connected, the piston rod of the same horizontal pressurized cylinder in lower end of described pressurization lever is hinged; The end of pressurized cylinder is hinged with frame; Described pressurized cylinder is connected with air supply system.
The beneficial effects of the utility model: due to design feature of the present utility model, when the utility model is used, overall structure is issued to a balance in the effect of pressurized cylinder and pressing spring; When the amounts of thickness variation of ribbon hour, pressing spring can fully reflect the varied in thickness of ribbon, detects sensitive.When the amounts of thickness variation of ribbon is larger, power can be delivered on pressurized cylinder, and pressurized cylinder can make the utility model whole system set up new balance; Can not only reach like this and detect sensitive object, and keep being applied in the pressure detecting between roller, large variation can not occur.When processing compression property differs larger fiber, without the active length of adjusting pressing spring, as long as adjust the output pressure of pressure regulator valve, can change the operating pressure of pressue device, when increasing substantially operating efficiency, also improved the quality of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing 1 be frame, 2 for fixing roller, 3 for dance roller, 4 for detect swing arm, 5 for pressing spring, 6 for pressurization lever, 7 for pressurized cylinder, 8 for electromagnetic valve, 9 for pressure regulator valve, 10 for source of the gas filtration Control Component, 11 be source of the gas.
The specific embodiment
The utility model comprises frame 1, in frame 1, be provided with fixedly roller 2 and the dance roller 3 with detection swing arm 4, the upper end of detecting swing arm 4 is hinged with frame 1, it is characterized in that: hingedly in described frame 1 be provided with the pressurization lever 6 identical with described detection swing arm 4 directions, between the middle part of the lower end of described detection swing arm 4 and pressurization lever 6, by horizontal pressing spring 5, be connected, the piston rod of the same horizontal pressurized cylinder 7 in lower end of described pressurization lever 6 is hinged; The end of pressurized cylinder 7 is hinged with frame 1; Described pressurized cylinder 7 is connected with air supply system.
Described air supply system comprises source of the gas 11, and source of the gas 11 filters Control Component 10 by source of the gas and with pressure regulator valve 9, is connected with electromagnetic valve 8 successively; Electromagnetic valve 8 is connected with described pressurized cylinder 7.
When the utility model is used, pressurized cylinder 7 and pressing spring 5 make whole system in equalising torque state, due to feeding fixedly the ribbon thickness between roller 2 and dance roller 3 can change, whole moment poised state of the present utility model is by destroyed.When the power that the varied in thickness of ribbon produces, while being delivered on the piston rod of pressurized cylinder 7, if this power is less than the piston of pressurized cylinder 7 and the stiction between cylinder body, the piston rod of cylinder can not move; But, the varied in thickness of feeding ribbon, the tensile elongation that can affect pressing spring 5 changes; So will there is minor alteration to the ribbon moulding pressure detecting between roller in pressue device at this moment.
The power producing when the varied in thickness of ribbon, while being delivered on the piston rod of pressurized cylinder 7, if when this power is greater than the piston of cylinder and the stiction between cylinder body, the piston of cylinder will move, and the equilibrium relation of above-mentioned two moments will be re-established.
In the utility model, use pressurization lever 6 as pressing spring 5 connector with pressurized cylinder 7, have two effects: the first, can increase the stability of compression system, prevent that pressing spring 5 from prolonging the axial wobble that detects swing arm 4; The second, remain that the piston rod of pressurized cylinder 7 is axially loaded state, avoid because piston rod is subject to radial load, making increases frictional resistance between piston rod and cylinder wall.
Due to above-mentioned characteristic of the present utility model, make this device highly stable to ribbon applied pressure between detection roller.The stability that the utility model is exerted pressure mainly determines by the characteristic of pressurized cylinder 7, the piston of cylinder and the stiction between cylinder body is lower, applied pressure is more stable.When the utility model is exerted pressure, the accuracy of adjustment mainly determines by the characteristic of pressure regulator valve 9, and the precision of voltage regulation of pressure regulator valve 9 is higher, and the accuracy of adjusting this device power output is higher.When changing the different fiber of processing compressibility, only need can complete by adjusting the pressure of air supply system.
