Abstract
The invention relates to the field of textile machinery, in particular to a yarn gripping mechanism on a weft insertion sword. The yarn gripping mechanism comprises an upper yarn gripper and a lower yarn gripper, wherein the upper yarn gripper comprises a fixed section, an elastic section and a clamping section; the yarn gripping mechanism also comprises an adjusting device which comprises an elastic part, an adjusting rod and an adjusting cap, the adjusting rod penetrates through the upper yarn gripper and the lower yarn gripper, and the elastic part and the adjusting cap respectively prop against the upper yarn gripper and the lower yarn gripper to adjust clamping force of the upper yarn gripper and the lower yarn gripper. The adjusting device is arranged, so that yarn clamping tension between the upper yarn gripper and the lower yarn gripper is controlled by the adjusting device, and can be adjusted according to practical situations, the application scope of the yarn clamping tension is widened, and a rapier loom is enabled to meet the requirement of weaving more products; meanwhile, the upper yarn gripper is provided with an elastic section, so that the upper yarn gripper has certain elastic force, and the yarn clamping tension can be finely adjusted to keep a proper magnitude.
Description
Technical field
The present invention relates to field of textile machinery, be specifically related to a kind of yarn clamping mechanism sent on latitude sword.
Background technology
The weft transfer of Rapier looms has come by sending latitude sword, the existing latitude sword that send is made up of sword shell, yarn gripper, guide sheet, cavernous body etc., yarn gripper is the parts sending most critical on latitude sword, and yarn gripper is arranged on sword shell, and below is lined with cavernous body elastomeric material.Send the yarn clipping of latitude sword to be come by the upper folder of yarn gripper and lower folder, yarn clipping surface tension relies on the natural resiliency being arranged on cavernous body between sword shell and yarn gripper to adjust, and because cavernous body its own resilient does not reach the tensile requirements of yarn clipping, its tension adjustment amplitude is little.Therefore to there is elasticity inflexible for existing yarn gripper, the problem of yarn clipping tension adjustment difficulty, and cavernous body is as elastomer simultaneously, and its fatigue resistance is poor, easily aging, makes cavernous body lose its due effect in yarn gripper, causes caused by loom stop.Such as: a kind of arrow shaft mechanism described in the patent No. 200720184084.4 send the yarn gripper on latitude sword, comprise folder, press from both sides with upper the lower folder coordinated, a waist hole is established at upper folder middle part, the lower clamping pull bar that connects, pull bar is through the waist hole of upper folder, be connected with the flexure strip be placed in above upper folder, its shortcoming is that the yarn clipping tension force of this yarn gripper is provided by flexure strip, the size of yarn clipping tension force depends on the material with flexure strip, its size is fixed value, can not adjust, in repeatedly working, therefore cause the elastic force of flexure strip to reduce gradually, yarn can not be clamped well.
Summary of the invention
The object of this invention is to provide a kind of yarn clamping mechanism sent on latitude sword, yarn clipping tension force can be adjusted, clamp yarn better.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: a kind of yarn clamping mechanism sent on latitude sword, comprise yarn gripper and lower yarn gripper, described upper yarn gripper comprises canned paragraph, stretch section and gripping section, described yarn clamping mechanism also comprises adjusting device, described adjusting device comprises elastic component, adjusting rod and adjustment cap, described adjusting rod runs through yarn gripper and lower yarn gripper, described elastic component and adjustment cap are arranged on adjusting rod, described elastic component and adjustment cap prop up yarn gripper and lower yarn gripper respectively to regulate the clamping force of upper yarn gripper and lower yarn gripper.
As preferably, described stretch section and lower yarn gripper are provided with corresponding adjustment hole, and described adjusting rod is located in adjustment hole.
As preferably, described adjusting rod is screw rod, and the one end which is provided with elastic component is provided with stop part, and described adjustment cap is provided with through hole, is provided with the internal thread with adjusting rod threaded engagement in through hole.
As preferably, described elastic component is spring or shell fragment.
As preferably, described stretch section is a uniform thickness body, and its thickness is less than the thickness of canned paragraph and gripping section.
As preferably, described gripping section is provided with crimping near the position of stretch section, and described lower yarn gripper is provided with the jaws corresponding with crimping.
As preferably, described crimping is arc convex, and described jaws is arc groove.
As preferably, described gripping section is provided with arc opening near lower yarn gripper place.
The present invention has following beneficial effect: the present invention is provided with adjusting device, yarn clipping tension force between yarn gripper and lower yarn gripper is controlled by adjusting device, yarn clipping Tensity size can be carried out according to actual conditions, expand the scope of application of yarn clipping tension force, what make Rapier looms adaptation more products weaves demand, goes up yarn gripper simultaneously and is provided with stretch section, make yarn gripper possess certain elastic force, can finely tune yarn clipping tension force, make the size that yarn clipping tension force keeps suitable.
