Abstract
The utility model announces a kind of automatic weft tension control device, belongs to industrial weaving technology field.Rotary cylinder including process support frame and on process support frame；Power rail is fixed with the periphery of the rotating shaft of the rotary cylinder；The power boom end is hinged with driving lever；Connecting rod is hinged with the middle part of the driving lever, the connecting rod other end is hinged on the end face of the rotating shaft of rotary cylinder.Rotary cylinder connects source of the gas by control loop, and the magnetic valve of control rotary cylinder rotating is provided with the control loop.On the one hand when throwing a spear, the tension force of weft yarn is kept relatively constant the utility model during whole beating, is not in the phenomenon that tension force rises and falls, be ensure that the quality of spacer screen；On the other hand it is to assist temple work, spacer screen will not be caused to be shunk on the position of both sides excessive.
Description
Technical field
Industrial weaving technology field is the utility model is related to, specifically a kind of automatic weft tension control device.
Background technology
During woven, the warp let-off and wefting insertion are two wherein mostly important links.After usual warp thread is by reed,
Side shoring mechanism can be installed in the both sides of loom to strut the split at fell, fabric lateral tension, the cloth for preventing from weaving is in width
Shrink to reach stable fell in degree direction；In addition, when reed moves, inclined side warp thread and reed friction, temple can subtract
It is few because edge warp thread tilt it is excessive and caused by broken end and side dent excessive wear.
And in terms of wefting insertion, although tension force when being provided with tension control element in shuttle to control wefting insertion, wefting insertion mistake
Journey is intermittent, if yarn intermittent unwinding from bobbin, can cause the fluctuation of weft tension, excessive weft tension peak value
Weft breakage and various wefting insertion faults will be produced, now tension force also tends to uncontrolled, and can produce the significantly contraction of selvedge.
The content of the invention
In order to solve the above technical problems, the utility model provides a kind of automatic weft tension control device, on the one hand, its energy
Enough automatic constant tensions for keeping weft yarn in the process of beating, on the other hand can keep selvedge not shrink significantly.
What the purpose of this utility model was realized in：A kind of automatic weft tension control device, including process support frame
With the rotary cylinder on process support frame；Power rail is fixed with the periphery of the rotating shaft of the rotary cylinder；It is described
Power boom end is hinged with driving lever；Connecting rod is hinged with the middle part of the driving lever, the connecting rod other end is hinged on the rotating shaft of rotary cylinder
End face.
It is further：The rotary cylinder connects source of the gas by control loop, and control is provided with the control loop
The magnetic valve of rotary cylinder rotating processed.
The driving lever is integrally triangular in shape, and driving lever lower end is acute angle tip.
The utility model is installed to loom edge by process support frame.When loom, which starts beating, throws a spear, shuttle triggering
Magnetic valve, at this moment, solenoid valve control rotary cylinder rotate forward, and driving lever, which pushes, catches on yarn to control throwing a spear for weft yarn；When a wheel is thrown
After tatting beam, shuttle triggers magnetic valve again, and at this moment, solenoid valve control rotary cylinder is inverted, and initial position is moved back on driving lever.
Compared with prior art, the beneficial effects of the utility model：On the one hand when throwing a spear, the tension force of weft yarn is entirely being beaten
It is kept relatively constant during latitude, is not in the phenomenon that tension force rises and falls, ensure that the quality of spacer screen；On the other hand it is to assist side
Work is supportted, spacer screen will not be caused to be shunk on the position of both sides excessive.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment one（When driving lever resets）；
Fig. 2 is the structural representation of the utility model embodiment one（When driving lever pushes）.
In figure：1st, process support frame；2nd, rotary cylinder；2-1, rotating shaft；3rd, power rail；4th, driving lever；5th, connecting rod.
Embodiment
It is a specific embodiment of the present utility model below, the utility model is described further in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of automatic weft tension control device, process support frame 1 are installed to loom edge, revolved
Rotaring cylinder 2 is arranged on process support frame 1.Power rail 3, power rail are fixed with the rotating shaft 2-1 of rotary cylinder 2 periphery
3 ends are hinged with driving lever 4, and the middle part of driving lever 4 is hinged with connecting rod 5, and the other end of connecting rod 5 is hinged on the rotating shaft 2-1 of rotary cylinder 2 end
Face, rotating shaft 2-1, power rail 3, driving lever 4 and connecting rod 5 form a four-bar mechanism；Driving lever 4 is overall triangular in shape, and the lower end of driving lever 4 is
Acute angle tip.Rotary cylinder 2 connects source of the gas by control loop, and source of the gas is that rotary cylinder 2 provides power, is set in control loop
It is equipped with the magnetic valve of the control rotating of rotary cylinder 2；Magnetic valve is arranged on process support frame 1, with shuttle in loom back and forth
Movement position is relative, and magnetic valve can be according to action of throwing a spear come rotary cylinder 2 at the beginning and end of throwing a spear every time.
During beginning, driving lever 4 is located at peak；
When loom, which starts beating, throws a spear, shuttle triggering magnetic valve, at this moment, solenoid valve control rotary cylinder rotates forward, driving lever
Push and catch on yarn to control throwing a spear for weft yarn；
After a wheel throws a spear end, for shuttle by temple, shuttle triggers magnetic valve again, at this moment, solenoid valve control rotation
Cylinder is inverted, and initial position is moved back on driving lever.
