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 the arrow shaft loom in the textile industry, mainly relate to a kind of rapier loom weft insertion and use gripper head.
Background technology
At present, in the various new looms that textile industry is used, Rapier looms is simple in structure, and wide adaptability has obtained using widely.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 hook of high speed rollback firmly have certain tension force weft yarn and with the elastic rod clipped weft yarn; Make the passive clamping of weft yarn go into gripper head and accomplish the wefting insertion action; Thereby weft breakage appears in this kind filling insertion way easily reduces loom production efficiency, and problem appears radially batching etc. in weft yarn after when non-twist filament yarns such as weaving glass fiber, carbon fiber, tending to occur empty latitude, wefting insertion, and glass fabric of weaving out and carbon cloth often do not reach quality requirement.
Summary of the invention
To 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 right non-twist endless tow fibers such as glass fibre, carbon fiber of knitting of this gripper head.
To achieve these goals, technical solution of the present invention is:
A kind of Rapier looms is used gripper head; Comprise main rod body and be arranged on the sword head of main rod body front end, said main rod body front end has mounting groove, has positioning through hole in the direction of vertical mounting groove; Said sword head is made up of last yarn clipping sheet, following yarn clipping sheet, U type elastomeric element; Sword head front end is coniform, and U type elastomeric element two ends embed wherein from the tail end of last yarn clipping sheet, following yarn clipping sheet respectively, and last yarn clipping sheet, following yarn clipping sheet are provided with support; Support and U type elastomeric element are arranged in mounting groove, last yarn clipping sheet, down the support of yarn clipping sheet through bolted splice in positioning through hole.
Owing to adopted above technical scheme, adopt zigzag interlock mode between the last yarn clipping sheet of gripper head of the present invention and the following yarn clipping sheet, and by U type elastomeric element chucking power is provided between last yarn clipping sheet and the following yarn clipping sheet; The grip effect that this has just increased gripper head has reduced the empty latitude rate of Rapier looms, and last yarn clipping sheet and following yarn clipping sheet adopt the mode of active clipped weft yarn; Change the situation of the passive clipped weft yarn wefting insertion of gripper head on traditional Rapier looms, overcome the gripper head problem that the weft yarn appearance is radially curled when wefting insertion on traditional Rapier looms, thereby increased the knitted scope of Rapier looms; It is convenient that the last U type elastomeric element that uses of the present invention is changed; Rapier looms only gets final product with changing U type elastomeric element during the machine kind in change, and the gripper head of cone shape taper, makes gripper head air drag when high-speed motion reduce to minimum to its influence; Sword head of the present invention is by the 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 and get final product; This has just reduced unnecessary waste, has improved production efficiency greatly.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
Like Fig. 1,2,3, shown in 4, a kind of Rapier looms is used gripper head, and gripper head is made up of main rod body 1 and the sword head that is arranged on main rod body 1 front end; Said main rod body 1 front end is circular-arc, is parallel to main rod body 1 front end circular arc and has mounting groove 2, on the direction of vertical mounting groove 2, has circular positioning through hole 3; Positioning through hole 3 connects mounting grooves 2, and said sword head is by last yarn clipping sheet 5, yarn clipping sheet 6, U type elastomeric element 4 constitute down, last yarn clipping sheet 5, descends yarn clipping sheet 6 front end indentations; Last yarn clipping sheet 5, yarn clipping sheet 6 is provided with support down; Have through hole on the support, this hole size is consistent with positioning through hole 3, and last yarn clipping sheet 5, the support and the U type elastomeric element 4 of yarn clipping sheet 6 are arranged in mounting groove 2 down; Last yarn clipping sheet 5, down the support of yarn clipping sheet 6 through bolted splice in positioning through hole 3; U type elastomeric element 4 two ends respectively from last yarn clipping sheet 5, the tail end of yarn clipping sheet 6 embeds wherein down, makes yarn clipping sheet 5, descends yarn clipping sheet 6 front ends to be closed form, closed form sword head is coniform.
Operation principle (see figure 5) of the present invention
Gripper head is installed on the arrow shaft; On loom, install the location opening device 7 of yarn clipping sheet 5 and following yarn clipping sheet 6; Location opening device 7 need be installed on the movement locus of yarn clipping sheet 5 and following yarn clipping sheet 6; The installing space of location opening device 7 is less than the spacing of last yarn clipping sheet 5 and following yarn clipping sheet 6 tail ends, and greater than the spacing at last yarn clipping sheet 5 and following yarn clipping sheet 6 support places.When loom begins the wefting insertion action; When arrow shaft promoted the gripper head motion, the last yarn clipping sheet 5 and following yarn clipping sheet 6 front ends of gripper head were closure state, along with the continuation campaign of gripper head; The gripper head motion is when locating opening device 7; The last yarn clipping sheet 5 of sword head will touch location opening device 7 with the tail end of following yarn clipping sheet 6, and location opening device 7 is given last yarn clipping sheet 5 and 6 one grasping forces of following yarn clipping sheet, and the front end of yarn clipping sheet 5 and following yarn clipping sheet 6 is opening under the effect of grasping force; Along with the continuation campaign of arrow shaft, the front end of yarn clipping sheet 5 and following yarn clipping sheet 6 is opened the zone on the weft yarn 8 entering gripper heads.At this moment, arrow shaft begins rollback, and the front end of last yarn clipping sheet 5 and following yarn clipping sheet 6 leaves location opening device 7 and is closure state, and clipped weft yarn 8 begins to do the wefting insertion action, and when arrow shaft rollback to starting point, loom is accomplished its wefting insertion and moved.
