TECHNICAL FIELD

[0001] The application discloses a textile equipment, in particular to a warp beam after the structure distribution of the edge bar loop warp knitting machine. BACKGROUND

[0002] The warp knitting fabric is prone to loop in the warp knitting production process, which is caused by the fact that one or more fibers on the surface of the fabric form fluff under the action of external friction during the weaving process, and then the fluff is continuously entangled and wound to form a spherical state under the continuous action of the friction.

[0003] The generation of the loop in the warp knitting fabric is prone to affect the processing, which affects the physical properties and appearance, especially the small edge bar under the condition of less number of yarn supply, which brings great difficulty to the front preparation and warping.

It should be understood that, in the description of the present application, the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are merely used for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of the present application.

[0036] A warp beam after the structure distribution of the edge bar loop warp knitting machine.

[0037] Embodiment one:

[0038] As shown in Figure 1 , comprising the following mechanisms:

[0039] The creel 1 is provided with a plurality of bobbins 2 for winding warp yarns, and is used for drawing and releasing the warp yarns. The creel 1 is provided with magnetic damping to resist the resistance of the counter roller to generate yarn tension, and the damping force is adjusted collectively to adapt to the uniformity of the spinning tension. According to the different front and back, up and down positions of the warp yarns drawn out of the creel 1, a plurality of sections are divided.

[0040] The lease device is provided with a lease frame 3 provided with a plurality of lease reeds 4, and is used for leasing the warp yarns drawn out of the bobbins 2.

[0041] The warping device includes a gauge reed 5 for controlling the number of warp yarns, a measuring roller 7 and a measuring roller 6 for measuring the length of the warp yarns and controlling the full shaft self-stop, a warping guide roller 9, and a roller 10 for winding the warp yarns. The gauge reed 5 is in the form of a straight line, and the width of each textile area and the edge bar area can be adjusted by adjusting the inclination angle of the straight-line gauge reed 5.

[0042] The reverse shaft device includes a warp beam 13 and a presser roller 14.

[0043] A waxing device is also provided between the warping device and the rewinding device. The waxing device includes two waxing guide rollers 12, a waxing roller 11, and a wax outlet platform 16. The top center of the wax outlet platform 16 has a wax outlet groove 15 containing wax emulsion. The waxing roller 11 is located above the wax outlet groove 15 and in contact with the wax emulsion. The waxing guide rollers 12 are symmetrically installed on both sides of the waxing roller 11. The two waxing guide rollers 12, the waxing roller 11, and the wax outlet platform 16 are all arranged in parallel. The diameter of the waxing roller 11 is greater than [missing information]. Waxing guide roller 12 is located at the upper end of the two sides of the wax outlet groove 15. When spinning and gluing, waxing roller 11 is immersed in wax emulsion and the wax emulsion is attached to the surface. As the waxing guide roller 12 conveys, the wax emulsion is coated on the spinning yarn. The fixed reed 5 is equipped with photoelectric breakage self-stop plate 8. Due to the uneven warp tension in the spinning area and the edge strip area, yarn breakage is likely to occur when the roller 10 and the warp beam 13 are wound. The photoelectric breakage self-stop plate 8 is used to detect and stop the machine.

[0044] When warping is carried out in sections, the warp yarns are layered and embedded into the yarn strips according to the weaving pattern by means of the reed 4 of the splitting device, so that the boundary between the weaving area and the edge strip area is clear.

[0045] Example 2:

[0046] like Figure 2 As shown, the warp yarn warping configuration of warp beam 13 and roller 10 is as follows:

[0047] S1, the total number of warp yarns in the complete weaving of the fabric is divided into X groups of weaving areas, and Y groups of edge strip areas are reserved in adjacent weaving areas;

[0048] S2, the warp yarns of the 17th warp section are fed into the edge strip area;

[0049] In S1 and S2, the warp yarn arrangement density in the textile zone and the edge strip zone is the same as that of warp beam 13, and the warp yarn width in each textile zone and edge strip zone is... Ensure that warp beam 13 can cover the width of the weaving area and the edge strip area;

[0050] In S3, the warp yarns of the textile zone and the edge strip zone are wound onto the roller 10 in the order arranged in S1 and S2. In S3, when the warp yarns of the textile zone and the edge strip zone are wound, the warp yarn width of the next textile zone or edge strip zone is shifted laterally when the warp yarns of each textile zone or edge strip zone are wound. The number of warp yarns in the textile zone is an integer multiple of the warp yarn arrangement cycle in the edge strip zone. A zone contains one or more edge strip zones, which reduces yarn rework and is suitable for small area edge strip weaving.

[0051] S4, after the warp yarns of the textile zone and the edge strip zone in S3 are wound onto the roller 10, they are unwound and rolled onto the warp beam 13.

[0052] Example 3:

[0053] like Figures 3-4As shown, the front end of the beaming device is provided with a let-off control device, the let-off control device includes an EBA / EBC electronic let-off system and a local let-off assembly 18, the local let-off assembly 18 includes a support 19 rotatable movably through a swing arm 20, a plurality of yarn guides 23 mounted on the support 19, a plurality of spools 17 drivenly coupled with the EBA / EBC electronic let-off system through a chain wheel 22 and a chain 21, the warp yarns wound on the spools 17 are guided to be wound around the beaming device after being passed through the lease rods 4 of the lease rod frame 3 and being pulled by the yarn guides 23.

[0054] During beaming, the warp yarns are arranged and configured according to the capacity of the creel 1, the warp yarns of the weaving area and the warp yarns of the selvedge area, and the warp yarns are wound closely and in parallel on the beaming drum 10 according to the width and length of the fabric process requirement, the let-off of the spools 17 is controlled by the EBA / EBC electronic let-off system to drive the let-off beam 13, and the let-off stretch ratio is ensured.
