The overload type yarn tension device is characterized in that the float cylinder comprises an upper cap and a lower cap which is sleeved with the upper cap; an inner cavity is formed by buckling the upper cap and the lower cap; springs are arranged in the cavity; the two ends of each spring abut against the inner wall of the upper cap and the inner wall of the lower cap correspondingly; the lower cap is fixedly arranged; the upper cap can float vertically according to pressure exerted by yarn; a pressure groove for the yarn to pass is formed in the top of the upper cap; a guide wheel is arranged in the pressure groove; a cutter rod is fixed to the lower cap; and the free end of the cutter rod is close to the guide wheel in the inner cavity.
Description
Technical field
The present invention relates to a kind of weaving device, particularly relate to a kind of overload type thread tension device.
Background technology
On yarn operating path, due to unwinding or foreign body stop etc. reason, yarn is the most blocked, the tension fluctuation amplitude causing yarn is bigger, so yarn enter weaving or enter doubling or entrance twist thread link waited Cheng Qian to need as far as possible to keep yarn tension unanimously or relatively minor swing scope, so can realize yarn and form the higher quality of production behind road under entering.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, it is provided that the overload type thread tension device of a kind of simple in construction.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of overload type thread tension device, including: the yarn guiding wheel set gradually along described thread path, floating drum, yarn guiding wheel, it is characterized in that, described floating drum includes the upper cap that is set-located and lower cap, described upper cap mutual with lower cap buckle-shaped become inner chamber, described interior intracavity arranges spring, described both ends of the spring respectively props up described upper cap and the inwall of described lower cap, described lower cap is fixedly installed, described upper cap can fluctuate according to the pressure that yarn applies, described upper crown portion is provided with the indent passed through for yarn, it is provided with guide wheel in described indent, it is fixed with knife bar inside described lower cap, described knife bar free end is in the lumen near described guide wheel.
In a preferred embodiment of the present invention, described knife bar forms two points of a knife at its free end bifurcated.
In a preferred embodiment of the present invention, when yarn pressure causes described upper cap sinking displacement to reach overload, described point of a knife is positioned on the thread path near described guide wheel.
In a preferred embodiment of the present invention, described guide wheel, with described in upper shade during floating drum axially-movable, keeps yarn to become broken line or linear state on the thread path of yarn guiding wheel-guide wheel-yarn guiding wheel, and the pressure holding all the time of described yarn is on guide wheel.
In a preferred embodiment of the present invention, described knife bar stretches out bottom described lower cap.
The present invention solves defect present in background technology, and the present invention possesses following beneficial effect:
(1) structure that in use, cap and lower cap are buckled together mutually, can form a quasi-elastomer that can fluctuate, and it can buffer Yarn tension fluctuation, and gives supplementing of Tensity size fluctuation, and further functions as damping action.
(2) by arranging knife bar at interior intracavity, so by controlling under the upper cap naturalness when without yarn pressure holding, adjust the spacing of point of a knife distance guide wheel, this can be so that an appropriately distance can be selected, when yarn tension is sufficiently large, in yarn pressure holding, cap sinks to causing point of a knife touch yarn and cut off yarn, such limit define yarn tension excessive time actively broken yarn, it is to avoid continue to produce owing to yarn tension is excessive and the quality problems that cause.
(3) two cooperate between yarn guiding wheel and indent, yarn carries and is formed on the distinctive operating path of yarn, the bending degree of thread path is changed by floating of upper cap, floating drum is the most top, compensating the biggest to the tension force of yarn, floating drum the most on the lower, compensates the least to the tension force of yarn, when the position lower limit of upper cap can be three point on a straight line bottom two yarn guiding wheels and indent, now compensate to the tension force of yarn almost nil.
(4) indent forms hump structure, by being arranged on bottom peak valley by yarn, it is ensured that yarn will not be fled easily.
(5), in guide wheel is arranged on indent, rolling friction rather than sliding friction can be provided in the position of yarn with floating drum mere contact, reduce the frictionally damage of yarn.

Detailed description of the invention
Presently in connection with drawings and Examples, the present invention is further detailed explanation, and these accompanying drawings are the schematic diagram of simplification, and the basic structure of the present invention is described the most in a schematic way, and therefore it only shows the composition relevant with the present invention.
As shown in Figure 1, Figure 2 and Figure 3, a kind of overload type thread tension device, including: the yarn guiding wheel that sets gradually along thread path, floating drum, yarn guiding wheel, floating drum includes the upper cap that is set-located and lower cap, upper cap mutual with lower cap buckle-shaped become inner chamber, interior intracavity arranges spring, both ends of the spring respectively props up cap and the inwall of lower cap, lower cap is fixedly installed, and upper cap can fluctuate according to the pressure that yarn applies, and upper crown portion is provided with the indent passed through for yarn
The structure using cap and lower cap to be buckled together mutually, can form a quasi-elastomer that can fluctuate, and it can buffer Yarn tension fluctuation, and gives supplementing of Tensity size fluctuation, and further functions as damping action., it being provided with guide wheel in indent, inside lower cap, be fixed with knife bar, knife bar free end is in the lumen near guide wheel.
Knife bar forms two points of a knife at its free end bifurcated.By arranging knife bar at interior intracavity, so by controlling under the upper cap naturalness when without yarn pressure holding, adjust the spacing of point of a knife distance guide wheel, this can be so that an appropriately distance can be selected, when yarn tension is sufficiently large, in yarn pressure holding, cap sinks to causing point of a knife touch yarn and cut off yarn, such limit define yarn tension excessive time actively broken yarn, it is to avoid continue to produce owing to yarn tension is excessive and the quality problems that cause.
Two cooperate between yarn guiding wheel and indent, yarn carries and is formed on the distinctive operating path of yarn, the bending degree of thread path is changed by floating of upper cap, floating drum is the most top, compensating the biggest to the tension force of yarn, floating drum the most on the lower, compensates the least to the tension force of yarn, when the position lower limit of upper cap can be three point on a straight line bottom two yarn guiding wheels and indent, now compensate to the tension force of yarn almost nil.
When yarn pressure causes cap sinking displacement to reach overload, point of a knife is positioned on the thread path near guide wheel.
When guide wheel is with upper shade floating drum axially-movable, keeps yarn to become broken line or linear state on the thread path of yarn guiding wheel-guide wheel-yarn guiding wheel, and yarn pressure holding all the time is on guide wheel.
Knife bar stretches out bottom lower cap.
Indent forms hump structure, by being arranged on bottom peak valley by yarn, it is ensured that yarn will not be fled easily.
Guide wheel is arranged in indent, can provide rolling friction rather than sliding friction in the position of yarn with floating drum mere contact, reduce the frictionally damage of yarn.
Desirable embodiment according to the present invention is enlightenment above, and by above-mentioned description, related personnel can carry out various change and amendment completely in the range of without departing from this invention technological thought.The content that the technical scope of this invention is not limited in description, it is necessary to determine technical scope according to right.
