Abstract
The invention relates to a textile machinery part used on a rapier loom, and in particular relates to a rapier head used for wefting insertion on the rapier loom. The rapier head comprises a main rod body and a sword-like head arranged at the front end of the main rod body, wherein the front end of the main rod body is provided with a mounting slot, a positioning through hole is arranged in a direction vertical to the mounting slot, the sword-like head is composed of an upper yarn clamping piece, a lower yarn clamping piece and a U-shaped flexible assembly, the front end of the sword-like head is conical, the two ends of the U-shaped flexible assembly are respectively embedded into the upper yarn clamping piece and the lower yarn clamping piece from tail ends of the upper yarn clamping piece and the lower yarn clamping piece, the upper yarn clamping piece and the lower yarn clamping piece are respectively provided with a support, the supports and the U-shaped flexible assembly are arranged in the mounting slot, and the supports of the upper yarn clamping piece and the lower yarn clamping piece are hinged in the positioning through hole by virtue of bolts. According to the rapier head disclosed by the invention, the upper yarn clamping piece and the lower yarn clamping piece are meshed by adopting a zigzag manner, the condition that the rapier head on the traditional rapier loom passively clamps weft yarns during wefting insertion is changed, and the defect that the weft yarns crimp in radial direction during the wefting insertion of the rapier head on the traditional rapier loom is overcome, thus weaving range of the rapier loom is expanded.
Description
Technical field
The present invention relates to the textile machine parts that use on arrow shaft loom in textile industry, mainly relate to a kind of rapier loom weft insertion gripper head.
Background technology
At present, in the various new looms of textile industry application, Rapier looms is simple in structure, and wide adaptability is widely used.On existing Rapier looms, because gripper head the place ahead clamper structurally adopts the design of circular hook and the passive clipped weft yarn of elastic rod, when Rapier looms is weaved the gripper head circular hook of high speed rollback hook have some tension weft yarn and with elastic rod clipped weft yarn, make passive the clamping into gripper head of weft yarn complete wefting insertion action, this kind of filling insertion way easily occurs that thereby weft breakage reduces loom production efficiency, and at weaving glass fiber, during the non-twist filament yarn such as carbon fiber, tend to occur empty latitude, after wefting insertion the problem such as there is radially batching in weft yarn, the glass fabric of weaving out and carbon cloth often do not reach quality requirement.
Summary of the invention
For the problem of above-mentioned existence, the object of the present invention is to provide a kind of gripper head of positive clipped weft yarn, and the suitable non-twist endless tow fibers such as glass fibre, carbon fiber of knitting of this gripper head.
To achieve these goals, the technology of the present invention solution is:
A kind of rapier head for rapier loom, comprise main rod body and the sword head that is arranged on main rod body front end, described main rod body front end has mounting groove, direction at right angle setting groove has positioning through hole, described sword head consists of upper yarn clamping sheet, lower yarn clamping sheet, U-shaped elastomeric element, sword head front end is coniform, U-shaped elastomeric element two ends embed wherein from the tail end of upper yarn clamping sheet, lower yarn clamping sheet respectively, upper yarn clamping sheet, lower yarn clamping sheet are provided with support, support and U-shaped elastomeric element are arranged in mounting groove, the support of upper yarn clamping sheet, lower yarn clamping sheet by bolted splice in positioning through hole.
Owing to having adopted above technical scheme, between the upper yarn clamping sheet of gripper head of the present invention and lower yarn clamping sheet, adopt zigzag interlock mode, and by U-shaped elastomeric element, provide chucking power between upper yarn clamping sheet and lower yarn clamping sheet, this has just increased the grip effect of gripper head, reduced the empty latitude rate of Rapier looms, upper yarn clamping sheet and lower yarn clamping sheet adopt the initiatively mode of clipped weft yarn, changed the situation of the passive clipped weft yarn wefting insertion of gripper head on traditional Rapier looms, overcome gripper head weft yarn when wefting insertion on traditional Rapier looms and occurred radially curling problem, thereby increased the knitted scope of Rapier looms, it is convenient that the U-shaped elastomeric element using in the present invention is changed, Rapier looms in change during machine kind only with changing U-shaped elastomeric element, and cone shape gripper head, make gripper head air drag when high-speed motion be down to minimum on its impact, sword head of the present invention is by loose mail assembly, so it is easy to assembly, when certain damage parts, needn't change whole gripper head, only need to change part of damage, this has just reduced unnecessary waste, greatly improved production efficiency.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As Fig. 1, 2, 3, shown in 4, a kind of rapier head for rapier loom, gripper head consists of main rod body 1 and the sword head that is arranged on main rod body 1 front end, described main rod body 1 front end is circular-arc, be parallel to main rod body 1 front end circular arc and have mounting groove 2, in the direction of at right angle setting groove 2, have circular positioning through hole 3, positioning through hole 3 connects mounting groove 2, and described sword head is by upper yarn clamping sheet 5, lower yarn clamping sheet 6, U-shaped elastomeric element 4 forms, upper yarn clamping sheet 5, lower yarn clamping sheet 6 front end indentations, upper yarn clamping sheet 5, lower yarn clamping sheet 6 is provided with support, has through hole on support, and this hole size is consistent with positioning through hole 3, upper yarn clamping sheet 5, the support of lower yarn clamping sheet 6 and U-shaped elastomeric element 4 are arranged in mounting groove 2, upper yarn clamping sheet 5, the support of lower yarn clamping sheet 6 is by bolted splice in positioning through hole 3, and U-shaped elastomeric element 4 is a shell fragment, and shell fragment two ends are respectively from upper yarn clamping sheet 5, the tail end of lower yarn clamping sheet 6 embeds wherein, makes yarn clamping sheet 5, lower yarn clamping sheet 6 front ends are closed form, and closed form sword head is coniform.
Operation principle of the present invention (seeing Fig. 5)
Gripper head is arranged on arrow shaft, on loom, install the locating open opening device 7 of yarn clamping sheet 5 and lower yarn clamping sheet 6, locating open opening device 7 need be arranged on the movement locus of yarn clamping sheet 5 and lower yarn clamping sheet 6, the installing space of locating open opening device 7 is less than the spacing of yarn clamping sheet 5 and lower yarn clamping sheet 6 tail ends, and is greater than the spacing at yarn clamping sheet 5 and lower yarn clamping sheet 6 support places.When loom starts wefting insertion action, when arrow shaft promotes gripper head motion, the upper yarn clamping sheet 5 of gripper head and lower yarn clamping sheet 6 front ends are closure state, continuation campaign along with gripper head, gripper head motion is when locating open opening device 7, the upper yarn clamping sheet 5 of sword head and the tail end of lower yarn clamping sheet 6 will touch locating open opening device 7, locating open opening device 7 is given upper yarn clamping sheet 5 and 6 one grasping forces of lower yarn clamping sheet, on under the effect of grasping force, the front end of yarn clamping sheet 5 and lower yarn clamping sheet 6 is opening, continuation campaign along with arrow shaft, weft yarn 8 enters the front end of yarn clamping sheet 5 and lower yarn clamping sheet 6 on gripper head and opens region.At this moment, arrow shaft starts rollback, and the front end of upper yarn clamping sheet 5 and lower yarn clamping sheet 6 leaves locating open opening device 7 and is closure state, and clipped weft yarn 8 starts to do wefting insertion action, and when arrow shaft rollback is during to starting point, loom completes its wefting insertion action.
