Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile machinery, in particular to a yarn separation guide device of a warp knitting machine. Background Art
[0002] During the weaving process of the warp knitting machine, in order to ensure that the yarn can accurately pass through the yarn guide hole and enter the loop forming mechanism for weaving, a yarn separation guide device is required between the yarn disc and the yarn guide hole. The yarn separation guide device must also have the function of ensuring the yarn tension.
[0003] The yarn guide device has a yarn guide cap as a component, which is a guide part for changing the direction of the yarn. The yarn guide cap is a long strip part with a C-shaped or U-shaped cross section. The yarn guide cap is stuck on the support through its opening. Since the outer surface of the yarn guide cap has to withstand the continuous compressive friction of the yarn, and the yarn may also contain certain chemical substances, such as dyes, the design and material selection of the yarn guide cap usually need to take into account factors such as wear resistance, corrosion resistance, and high temperature resistance. For many years, since it has always been considered that the yarn guide cap is stuck on the support through elastic deformation, the yarn guide cap has always been made of stainless steel or chrome-plated steel. The surface hardness and surface smoothness of this type of yarn guide cap are insufficient. After surface wear, the passing yarn will be broken or entangled, and the yarn needs to be replaced at this time. That is, due to the yarn guide cap, the maintenance cost of the yarn guide device of the existing warp knitting machine is high, and yarn breakage and replacement of the yarn guide cap seriously affect the stable operation of the warp knitting machine and the quality of the fabric. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a yarn dividing guide device for a warp knitting machine, so as to overcome the problem that the existing yarn dividing guide device affects the operation of the warp knitting machine and the quality of the fabric.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a yarn dividing guide device of a warp knitting machine, the yarn dividing guide device is located between the yarn disk and the weaving mechanism, including a mounting plate for mounting the yarn dividing guide device on a crossbeam of the warp knitting machine, a tension square tube directly or indirectly mounted on the mounting plate, having a plurality of tension springs arranged on the tension square tube, a fixed part of the tension spring being fixed on the tension square tube, a tension sheet being provided on the elastic part of the tension spring, a first yarn guide cap with a C-shaped cross section, the first yarn guide cap opening facing the tension sheet and being snapped onto the tension sheet, having a yarn splitter, the yarn splitter being directly or indirectly mounted on the tension square tube, and the first yarn guide cap having a first sprayed ceramic layer on the outer surface.
[0006] Considering that the first yarn guide cap will be deformed when it is snapped onto the tension plate, but the first sprayed ceramic layer is brittle, it is necessary to first install the yarn guide cap blank that has not yet been sprayed with the first sprayed ceramic layer onto the tension plate, or to install several tension plates on the yarn guide cap blank first. If the tension spring and the tension plate are a connected structure, the tension spring and the tension plate are installed together on the yarn guide cap blank, and then the assembly is sent to the spraying workshop to spray only the ceramic layer on the outer surface of the yarn guide cap, and then the assembly is installed on the tension square tube. Therefore, this technical solution overcomes the technical prejudice that the existing yarn guide cap cannot use ceramic parts by changing the assembly method of the existing yarn dividing guide device.
[0007] Specifically, in order to reduce the wear of the yarn on the yarn splitter, a yarn splitting angle aluminum is provided, the length direction of the yarn splitting angle aluminum is consistent with the length direction of the tension square tube, one right-angle side of the yarn splitting angle aluminum is installed on the tension square tube, and a second yarn guide cap is fastened on the top edge of the other right-angle side, and the cross-section of the second yarn guide cap is C-shaped. The yarn splitter is located between the second yarn guide cap and the yarn disk, and the yarn splitter is installed on the yarn splitting angle aluminum, and the second yarn guide cap has a second sprayed ceramic layer on the outer surface.
[0008] As mentioned above, the second yarn guide cap blank is also previously snapped onto the yarn splitting angle aluminum, and then the second sprayed ceramic layer is sprayed on the cap blank, and then the yarn splitting angle aluminum is installed on the tension square tube.
[0009] Specifically, the thickness of the second sprayed ceramic layer of the second yarn guide cap is 0.1-1.0 mm.
[0010] Specifically, the thickness of the first sprayed ceramic layer of the first yarn guide cap is 0.1-1.0 mm.
[0011] Specifically, in order to improve the guiding accuracy of the yarn, overcome the offset of the position of parts caused by temperature and other reasons, and reduce the wear of the yarn, the tension square tube is indirectly installed on the mounting plate, and a square tube adjustment plate that can adjust the left and right positions of the tension square tube is provided between the tension square tube and the mounting plate. The square tube adjustment plate is fixed on the mounting plate, and a square tube placement groove is provided on the square tube adjustment plate. The groove wall of the placement groove is provided with a fastening bolt that presses against the tension square tube.
[0012] The beneficial effects of the utility model are as follows: the yarn dividing guide device of the warp knitting machine of the utility model, first, overcomes the existing technical prejudice, the outer surface of the yarn guide cap has a ceramic layer, which enhances the wear resistance, corrosion resistance and high temperature resistance of the yarn guide cap, and the ceramic coating has higher hardness and a smoother surface, which can reduce yarn wear, prevent yarn breakage and entanglement, make the warp knitting machine run stably and improve fabric quality; second, another yarn guide cap is arranged next to the yarn divider to better guide the yarn and reduce the wear of the yarn divider on the yarn; third, the left and right positions of the tension square tube can be adjusted, which can better align the yarn with the yarn guide hole, and also reduce the wear of the yarn and the wear of parts in contact with the yarn.
