Abstract
The utility model discloses a kind of warp knitting machine yarn-selector crochet hook, comprise syringe needle, pin mouth, the needle body and backshank; Described syringe needle, pin mouth, the needle body and backshank are made into integration, and the front end face of described syringe needle is the inclined-plane crossing with horizontal plane, and described pin mouth is an opening upwards and the open slot that takes the shape of the letter U of cross section.The described needle body is preferably cylindrical, and the upper and lower end face of described backshank is preferably plane, and the upper and lower end face of backshank to smoothly transit with the needle body respectively by circular arc and is connected.The front end face of described syringe needle and the U-shaped open slot of pin mouth preferably all tilt to needle body direction.Crochet hook of the present utility model, effectively can not only avoid interfering collision with miscellaneous part when weaving, and can effectively prevent the accident of stretch-broken yarn from occurring, and mounting or dismounting are convenient, long service life, and the accuracy hooking yarn is high, hooks yarn effective.
Description
Technical field
The utility model relates to a kind of knitting mechanism of warp knitting machine, particularly relates to the crochet hook for yarn-selector in a kind of knitting mechanism of warp knitting machine, belongs to warp knitting field.
Background technology
Warp knitting machine is in weave pattern patterning process, part yarn is not be all in woven condition always, according to designing program of flower pattern technique, some yarn may after formation decorative pattern, weave pattern structural state will be departed from, by the time next decorative pattern may participate in again braiding, and these yarns not participating in weaving are chosen out by the crochet hook in yarn-selector, make it to exit woven condition.Existing crochet hook, comprises syringe needle, pin mouth, the needle body and backshank; Described syringe needle, pin mouth, the needle body and backshank are made into integration, and the front end face of syringe needle is the perpendicular end surface crossing with horizontal plane.The crochet hook of existing structure in use, syringe needle due to crochet hook other parts that are frequent and warp knitting machine interfere, and it is inaccurate that the pin mouth of crochet hook not only hooks yarn, but also the accident of stretch-broken yarn often occurs, therefore the result of use of existing crochet hook is very undesirable.
Summary of the invention
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of and can not only effectively avoid interfering collision with miscellaneous part when weaving, and effectively can prevent the warp knitting machine yarn-selector crochet hook of stretch-broken yarn.
For solving the problems of the technologies described above, the utility model adopts so a kind of warp knitting machine yarn-selector crochet hook, comprises syringe needle, pin mouth, the needle body and backshank; Described syringe needle, pin mouth, the needle body and backshank are made into integration, and the front end face of described syringe needle is the inclined-plane crossing with horizontal plane, and described pin mouth is an opening upwards and the open slot that takes the shape of the letter U of cross section.
In the utility model, the described needle body is preferably cylindrical, and the upper and lower end face of described backshank is preferably plane, and the upper and lower end face of backshank to smoothly transit with the needle body respectively by circular arc and is connected.
In the utility model, the front end face of described syringe needle and the U-shaped open slot of pin mouth preferably all tilt to needle body direction.
After adopting said structure, the utility model has following beneficial effect:
Because the front end face of the utility model syringe needle is the inclined-plane crossing with horizontal plane, thus greatly reducing contact area, therefore can effectively avoid interfering collision with the miscellaneous part of warp knitting machine when weaving.
Because the utility model pin mouth is an opening upwards and the open slot that takes the shape of the letter U of cross section, therefore can effectively prevent the accident of stretch-broken yarn from occurring when weaving.
Upper and lower end face due to the utility model backshank is plane, is therefore more conducive to installation and removal.
Because the U-shaped open slot of the utility model pin mouth tilts to needle body direction, be therefore more conducive to reliability and accuracy rate that crochet hook hooks yarn.
The long service life of the utility model crochet hook, hooks yarn accuracy high, hooks yarn effective.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model warp knitting machine yarn-selector crochet hook.
Fig. 2 is the schematic front view of the utility model warp knitting machine yarn-selector crochet hook.
Fig. 3 is the schematic top plan view of the utility model warp knitting machine yarn-selector crochet hook.
Detailed description of the invention
See a kind of warp knitting machine yarn-selector crochet hook shown in Fig. 1 to Fig. 3, comprise syringe needle 1, pin mouth 2, the needle body 3 and backshank 4; Described syringe needle 1, pin mouth 2, the needle body 3 and backshank 4 are the single piece be made into integration by steel, the front end face 1-1 of described syringe needle 1 is the inclined-plane crossing with horizontal plane, angle between described front end face 1-1 and horizontal plane can between 30 ~ 60 °, be preferably 45 °, described pin mouth 2 is an opening upwards and the open slot that takes the shape of the letter U of cross section.
In the utility model, as shown in Figure 1,2 and 3, the described needle body 3 is cylindrical, and upper and lower end face 4-1, the 4-2 of described backshank 4 are plane, and upper and lower end face 4-1, the 4-2 of backshank 4 to smoothly transit with the needle body 3 respectively by circular arc 5 and be connected.
In the utility model, as shown in Figure 1, 2, the front end face 1-1 of described syringe needle 1 and the U-shaped open slot of pin mouth 2 all tilt to the needle body 3 direction.
In addition, the equal rounding of all seamed edges of the utility model crochet hook, can avoid the burr plucking yarn in braiding process on seamed edge like this, affect the intensity of yarn.
Crochet hook of the present utility model is arranged in yarn-selector, and during work, elastic motion done by crochet hook, chooses out, make it to exit woven condition by the yarn not participating in weaving.
Crochet hook of the present utility model not only structure is simple, long service life, and structure is more conducive to instructions for use, and the accuracy hooking yarn is high, hooks yarn effective.
