Description
Technical field
The present invention 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, to be transported to drafting system through the ribbon of measuring again, 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, to the measurement of feeding ribbon total amount, be 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, apply a stable pressure at this to detecting between roller.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 one 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.Complete after the pressurization to detecting roller at cylinder, 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.In the time that the Thickness Ratio of ribbon in detection roller is thinner, spring is smaller to detecting roller applied pressure; In the time that the Thickness Ratio of ribbon in detection roller is thicker, spring is larger to detecting roller applied pressure., 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.In the time that 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 ensure the precision of adjustment.
Summary of the invention
The present invention is exactly for the problems referred to above, provides one to 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 invention, the present invention adopts following technical scheme, the present invention includes frame, in frame, be provided with fixing roller and there is the dance roller that detects 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, be connected by horizontal pressing spring, 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.
Beneficial effect of the present invention: due to design feature of the present invention, when the present invention uses, 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.In the time that the amounts of thickness variation of ribbon is larger, power can be delivered on pressurized cylinder, and pressurized cylinder can make whole system of the present invention 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.In the time that 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 improve the quality of product.
Brief description of the drawings

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 be source of the gas for source of the gas filters Control Component, 11.
Detailed description of the invention
The present invention includes frame 1, in frame 1, be provided with fixing roller 2 and there is the dance roller 3 that detects 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, be connected by horizontal pressing spring 5, 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 is connected with electromagnetic valve 8 with pressure regulator valve 9 successively; Electromagnetic valve 8 is connected with described pressurized cylinder 7.
When the present invention uses, pressurized cylinder 7 and pressing spring 5 make whole system in equalising torque state, and because the ribbon thickness between the fixing roller 2 of feeding and dance roller 3 can change, overall moment poised state of the present invention 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 stiction between piston and the cylinder body of pressurized cylinder 7, 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 stiction between piston and the cylinder body of cylinder, the piston of cylinder will move, and the equilibrium relation of above-mentioned two moments will be re-established.
In the present invention, 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 invention, make this device highly stable to ribbon applied pressure between detection roller.The stability that the present invention exerts pressure mainly determines by the characteristic of pressurized cylinder 7, and stiction between piston and the cylinder body of cylinder is lower, applied pressure is more stable.When the present invention exerts 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.In the time changing the different fiber of processing compressibility, only need can complete by the pressure of adjusting air supply system.
