Description
Technical field
The utility model relates to field of fixtures, is specifically related to a kind of New Type Jet cotton yarn clamper.
Background technology
Water jet looms wefting insertion is medium with water, and the strength utilizing water flow jet to produce drives weft yarn to enter shed open.Shi Chanmian big country of China, cotton cultivated areas is distributed more widely, and output is higher.Cotton fiber is with its good moisture absorption, gas permeability extremely consumers.The cross section of cotton fiber is tubulose kidney ellipsoid, and cavity length accounts for 85% of fiber overall length.Longitudinal profile has rope form and turns bent, and length is 1000 times ~ 3000 times of width, and expand after meeting water and do not dissolve, elongation at break is 7% ~ 12%, and surely extending rebound degree (extending 2%) is 74%, regain 11.1%.Water jet looms relies on current to carry out wefting insertion, and the flight of weft yarn is free state.Water stream cause shed open near region through weft yarn and Fabric wettability, thus affect larger by the kind of raw material, the factor such as state and shed shape.Due to the constraint of various condition, water jet looms was used for that official regain is less than 10%, elongation at break is greater than weaving of 8.8% yarn in the past.Percentage elongation due to cotton fiber is 7% ~ 12%, therefore cotton belongs to and can not weave yarn on water jet looms, one of difficult point is the problem of wefting insertion, because the extension at break of cotton yarn is less, be easy to cause weft yarn tension failure in wefting insertion process, make to weave and cannot normally carry out, this is the key point that water jet looms can not weave cotton yarn, the utility model can the moment (when the weft yarn from clamper to strand limit yarn becomes the length from clamper to cloth fell) in wefting insertion process supplement weft yarn, it is avoided to bear larger elongation, solve the problem of cotton yarn easy fracture, realize weaving continuously of cotton yarn.
Utility model content
The purpose of this utility model is to overcome prior art Problems existing, provides a kind of New Type Jet cotton yarn clamper.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of New Type Jet cotton yarn clamper, it mainly comprises the big cam that links together and little cam, is arranged on the cam follower of described big cam, little cam side, the cam link of described cam follower is installed, the clamper connecting rod of affixed described cam link, by the clamp axis that described clamper connecting rod one end prizes, be arranged at the movable plate of described clamp axis upper end, wherein, also be connected with a weft replenishment cam in described big cam side, described weft replenishment cam abuts little cam.
Further, between described weft replenishment cam, big cam and little cam, relative position is adjustable.
Further, described weft replenishment cam, big cam and little cam form an integral cam, and cam radius and extrusion position adjustable.
The beneficial effects of the utility model are:
Adopt technical solutions of the utility model, again can supplement weft yarn, prevent the problem of textile weft yarn tension failure after weft yarn place clamp position, and structure is simple, improvement cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure illustrates: 1, big cam, 2, little cam, 3, cam follower, 4, cam link, 5, clamper connecting rod, 6, rotating shaft, 7, rod spring, 8, clamp axis, 9, movable plate, 10, back-moving spring, 11, fixed head, 12, weft replenishment cam.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to shown in Fig. 1, a kind of clamp holder of water jet loom, comprise the big cam 1 and little cam 2 that link together, be arranged on big cam 1, the cam follower 3 of little cam 2 side, a weft replenishment cam 12 is connected with in described big cam 1 side, described weft replenishment cam 12 abuts little cam 2, described cam follower 3 is fixed on cam link 4, the affixed clamper connecting rod 5 of described cam link 4, and its fixing position is contained in a rotating shaft 6, described cam link 4 is connected with the rod spring 7 vertically arranged, described clamper connecting rod 5 one end is provided with clamp axis 8, described clamp axis 8 upper end is provided with movable plate 9, described clamp axis 8 is socketed on fixed head 11 slidably, described clamp axis 8 is installed with back-moving spring 10, one end of back-moving spring 10 pushes against fixed head 11, the other end pushes against on the shaft shoulder of clamp axis 8 lower end, back-moving spring 10 is in compressive state in clamp axis 8 total travel.
Between described weft replenishment cam 12, big cam 1 and little cam 2, relative position is adjustable, can make the adjustable relative position structure of rail slide type between weft replenishment cam 12, big cam 1 and little cam 2, or makes the adjustable relative position structure of bolt cellular type.
Described weft replenishment cam 12, big cam 1 and little cam 2 form a whole cam, and cam radius and extrusion position adjustable.
Principle of the present utility model:
During work, be divided into two large duties: pine folder weft yarn and supplementary weft yarn.Wherein press from both sides weft yarn: when the large radius after the combination of big cam 1, little cam 2 presses to cam follower 3, drive cam link 4 to lower swing, because cam link 4 and clamper connecting rod 5 are packed in same rotating shaft 6, therefore, the swing band moving axis 6 of cam link 4 rotates, and axle 6 drives clamper connecting rod 5 upwards to swing, hold up clamper axle 8, clamper movable plate 9 is upwards lifted, and at this moment, weft yarn is in release conditions; When the minor radius after the big cam 1 of clamper, little cam 2 combine forward to contact with cam follower 3 time, cam link 4 upwards swings under the pulling force effect of rod spring 7, drive clamper connecting rod 5 to lower swing, clamper axle 8 is at the elastic force moved downward of back-moving spring 10, drive clamper movable plate 9 to move downward, weft yarn is in by clamp position.
After the process of above-mentioned folder weft yarn, now draw the weft yarn that a segment length is fixing in clamper, if but now cotton yarn is carried out to the words of wefting insertion, if do not supplemented weft yarn, this section of weft yarn will bear larger elongation, because the extension at break of cotton yarn is less, causes breakage of weft, make to weave and cannot normally carry out, now weft replenishment cam 12 of the present utility model makes wefting insertion enter next process: supplement weft yarn.
Supplement weft yarn: the relative position of big cam l and little cam 2 remains unchanged, before reed does not encounter weft yarn, clamper closes, the tension force keeping weft yarn suitable and stability, treat that warp thread closes, after weft yarn is in complete slave mode, when the speed of mainshaft about 315, weft replenishment cam 12 by cam follower 3 to pressing down, make cam link 4 to lower swing, clamper connecting rod 5 is driven upwards to swing, promoting clamper axle 8 upwards drives clamper movable plate 9 to reopen, make reed in the process of beating motion, supplementary weft yarn is pulled out from clamper, less problem is extended to make up textile breakage of weft, the speed of mainshaft about 340 time, weft replenishment cam 12 is made to depart from cam follower 3, clamper is again closed in order to avoid weft yarn is excessively drawn.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
