Abstract
The invention discloses a warp tension acquiring device for a spinning machine. The device comprises a stand and a warp conveying guide wheel; a bracket is arranged on the stand; an oscillating rod is arranged at the free end of the bracket and can rotate around the free end; the oscillating rod is fixedly connected with a rotating shaft of the warp conveying guide wheel; a photoelectric sensing switch electrically connected with a warp conveying motor is arranged on the stand; a baffle which can rotate to trigger the photoelectric sensing switch is arranged on the oscillating rod. According to the device, the position of the warp conveying guide is changed as the warp tension increases, then the baffle triggers the photoelectric sensing switch to control the rotating speed of the motor and speed up the warp conveying, and as a result, the warp conveying speed can be adjusted on real time according to the change on the warp tension, and as a result, the tension can be kept balancing.
Description
technical fieldthe present invention relates to a kind of textile machine warp tension harvester, belong to textile technology field.
Background technology
in fabrication processes, warp let-off structure is a kind of requisite device, and the sensitivity level of let-off motion directly affects the control of warp tension, and the stable warp of tension force has vital effect for the quality of end product.
Existing let-off motion is generally pure mechanical structure, needs the particular fabric such as the change filling density of precise hard_drawn tuhes warp tension usually because tension force precision controlling does not reach corresponding requirement and cause end product quality to be guaranteed for some.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of textile machine warp tension harvester, can regulate warp let-off speed in real time according to the change of warp tension, ensures that tension force keeps balance.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of textile machine warp tension harvester, comprise support and warp let-off guide wheel, described support is provided with support, the free end of described support is provided with the fork that can rotate around it, described fork is fixedly connected with the rotating shaft of described warp let-off guide wheel, described support is provided with the photoelectric sensor switch be electrically connected with let-off motor, described fork is provided with and rotates by it washer triggering described photoelectric sensor switch.
Aforesaid a kind of textile machine warp tension harvester, is characterized in that: be also provided with tension spring between described fork and support.
Aforesaid a kind of textile machine warp tension harvester, is characterized in that: described fork is also provided with damper.
Aforesaid a kind of textile machine warp tension harvester, is characterized in that: described damper is viscoelastic damper.
The invention has the beneficial effects as follows: the change driving warp let-off idler positions when the change of warp tension is large, thus make washer trigger photoelectric sensor switch control motor speed, accelerate warp let-off speed, thus regulate warp let-off speed in real time according to the change of warp tension, ensure that tension force keeps balance.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of textile machine warp tension of the present invention harvester.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 1, a kind of textile machine warp tension harvester, comprise support 1 and warp let-off guide wheel 2, described support 1 is provided with support 3, the free end of described support 3 is provided with the fork 4 that can rotate around it, described fork 4 is fixedly connected with the rotating shaft of described warp let-off guide wheel 2, described support 1 is provided with the photoelectric sensor switch 6 be electrically connected with let-off motor, described fork 4 is provided with and rotates by it washer 5 triggering described photoelectric sensor switch 6.
The change of warp let-off guide wheel 2 position is driven when the change of the tension force of warp thread 9 is large, make it rotate, thus drive washer 5 to trigger photoelectric sensor switch 6 and control motor speed, accelerate warp let-off speed, thus regulate warp let-off speed in real time according to the change of warp tension, ensure that tension force keeps balance.
Also be provided with tension spring 7 between described fork 4 and support 1, when the tension force of warp thread recovers constant, by tension spring 7, warp let-off guide wheel 2 resetted.
Described fork 4 is also provided with damper 8, the damper 8 that the present embodiment adopts is viscoelastic damper, increase the cushion effect during invention change of warp let-off guide wheel 2 position, be that the tension variation of warp thread 9 is the processes slowly changed, prevent tension force cataclysm from causing it to rupture.
In sum, a kind of textile machine warp tension harvester provided by the invention, can regulate warp let-off speed in real time according to the change of warp tension, ensures that tension force keeps balance.
More than show and describe general principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is by appending claims and equivalent circle thereof.
