Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of textile equipment and relates to a platform device for adjusting the needle pressing depth of a needle cylinder triangle seat. Background Art
[0002] Various weaving defects may occur in the production process of knitted fabrics, such as horizontal stripes, vertical stripes, holes, thread loops, missed stitches, missed bottoms, and fancy stitches. Among them, horizontal stripes have the most influencing factors and are the most difficult to solve. The causes range from raw materials to equipment, processes, and even employee operations. Among them, the status of the equipment is the prerequisite for stable production, so the precision of each component of the equipment needs to be adjusted to the optimal state.
[0003] The components of a double-sided circular knitting machine include the following: a weaving mechanism, a transmission mechanism, a lubrication mechanism, a dust removal mechanism, a pulling and winding mechanism, a frame, and an electrical system. The most important of these is the weaving mechanism, which includes a cam, a cam, a knitting needle, a needle cylinder, a yarn storage device, and a yarn feed disc. Fabric formation depends on the knitting needles, which, under the action of the cam, move up and down within the needle groove of the needle cylinder while simultaneously making circular motion along the cam's needle path. Since knitted fabrics are composed of a series of coils, their primary structural unit is the coil, and the shape of the coils is directly reflected on the fabric. If the coil shapes are inconsistent, horizontal stripes will appear on the fabric, with the degree of variation corresponding to the degree of the difference. Factors affecting coil shape include the process, needle positioning, barrel height, and the depth of the cam's pressure needles, with the most significant being the depth of the cam's pressure needles.
[0004] The cam's pressure depth can be adjusted using the pressure knob on the cam base. The cam is fixed to the sword pin on the cam base with a screw. The cam base has an adjustment knob that can adjust the height of the sword pin. When the adjustment knob is turned, the cam follows the sword pin and the knitting needle clock also follows the adjustment of the cam, thereby changing the pressure depth, that is, the loop shape of the fabric.
[0005] The needle cylinder of the double-sided knitting machine includes an upper needle disc and a lower needle cylinder. The yarn tension is controlled by the needle pressing depth on the upper and lower triangular seats. Therefore, it is necessary to ensure that the needle pressing depth of the same weaving situation on different routes corresponds to each other. At this time, if the tension value on the tension meter is adjusted, the corresponding needle pressing depths of the upper needle disc and the lower needle cylinder will be inconsistent when the yarn tension is consistent, which will lead to the production of woven horizontal stripes on the grey fabric. Utility Model Content
[0006] The purpose of this utility model is to address the above-mentioned problems existing in the existing technology and to provide a platform device for adjusting the needle pressing depth of the needle cylinder triangle seat. The technical problem to be solved by this utility model is how to make the needle pressing depths of different numbers of needles on the needle cylinder correspond to each other and avoid the generation of horizontal stripes in the grey cloth.
[0007] The purpose of the present utility model can be achieved through the following technical solutions: a platform device for adjusting the needle pressing depth of the needle cylinder triangle seat, characterized in that it includes a base, a lever gauge and a limiting mechanism arranged on the base, the limiting mechanism includes a U-shaped positioning plate fixed to the base, the U-shaped limiting plate includes two end plates and a horizontal plate perpendicular to the two end plates, the two end plates and the horizontal plate form a mold with an opening, one of the end plates is provided with a socket, a guide rod is slidably connected in the socket, the outer end of the guide rod is fixedly provided with a pressure plate located at the opening of the mold, and a repulsion component is provided between the inner end of the guide rod and the U-shaped positioning plate to drive the pressure plate to press the triangle seat located in the mold.
[0008] Furthermore, the repulsion component includes a permanent magnet block 1 located at the inner end of the guide rod and a permanent magnet block 2 fixed on the U-shaped positioning plate, and the permanent magnet block 1 and the permanent magnet block 2 repel each other.
[0009] As another possibility, the repulsion component may also be a return spring in a compressed state, and the return spring is sleeved on the guide rod.
[0010] Furthermore, a handle is fixedly provided on the pressing plate.
[0011] During operation, first drive a cam with a standard depth and use it as a standard to measure the value displayed on the lever meter of the standard cam pressure needle. Then remove the standard cam and rotate other cams to be measured. When the pressure needle depth values of other cams to be measured are different from the pressure needle depth values of the standard cam, adjust the position of the cam pressure needle until it is consistent with the standard value, and complete the pressure needle depth of each cam one by one.
[0012] It should be noted that the depth of the pressing needle on the triangular seat can be adjusted by rotating the screw on the side of the triangular seat away from the pressing needle.
[0013] This solution can calibrate the pressing needle depth of the triangle seat so that the coils of the grey fabric are neat and the occurrence of horizontal stripes on the grey fabric is reduced.
[0014] The opening of the U-shaped positioning plate is completed by a simple structure that can quickly realize the disassembly and assembly of the triangle seat. Pulling the guide rod outward and rotating the guide rod can make the pressure plate open the opening of the U-shaped positioning plate, so that the triangle seat can be easily taken out and installed. Conversely, after the triangle seat is installed into the mold opening of the U-shaped positioning plate, pull outward and select the guide rod so that the pressure plate presses the triangle seat under the action of the repulsion component to ensure that the positions of all the triangle seats on the base are consistent, thereby improving the calibration accuracy.

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0019] like Figure 1 and Figure 2 The platform device for adjusting the needle pressing depth of the needle cylinder triangular seat shown in the figure includes a base 1, a lever gauge 2 and a limiting mechanism arranged on the base 1, the limiting mechanism includes a U-shaped positioning plate 3 fixed on the base 1, the U-shaped limiting plate includes two end plates and a horizontal plate perpendicular to the two end plates, the two end plates and the horizontal plate form a mold with an opening, one of the end plates is provided with a socket, a guide rod 4 is slidably connected in the socket, the outer end of the guide rod 4 is fixed with a pressure plate 5 located at the opening of the mold, and a repulsion component is provided between the inner end of the guide rod 4 and the U-shaped positioning plate 3 to drive the pressure plate 5 to press the triangular seat located in the mold.
[0020] The repulsive force assembly includes a permanent magnet 1 (6) located at the inner end of the guide rod 4 and a permanent magnet 2 (7) fixed to the U-shaped positioning plate 3. The permanent magnet 1 (6) and the permanent magnet 2 (7) repel each other. Alternatively, the repulsive force assembly may be a return spring in a compressed state, which is sleeved on the guide rod 4.
[0021] A handle 8 is fixedly provided on the pressing plate 5 to facilitate operation of the pressing plate 5 .
[0022] During operation, first drive a cam with a standard depth and use it as a standard to measure the value displayed on the lever gauge 2 of the standard cam pressure needle. Then remove the standard cam and rotate other cams to be measured. When the pressure needle depth values of other cams to be measured are different from the pressure needle depth values of the standard cam, adjust the position of the cam pressure needle until it is consistent with the standard value, and complete the pressure needle depth of each cam one by one.
[0023] It should be noted that the depth of the pressing needle on the tripod can be adjusted by rotating the screw on the side of the tripod away from the pressing needle. The position of the ejector pin of the lever gauge 2 in the needle groove of the tripod is different, and the displayed data is different. This is used to determine whether the position of the needle groove of the tripod is consistent. After the needle groove position is calibrated, the position of the pressing needle is calibrated.
[0024] This solution can calibrate the pressing needle depth of the triangle seat so that the coils of the grey fabric are neat and the occurrence of horizontal stripes on the grey fabric is reduced.
[0025] The opening of the U-shaped positioning plate is completed by a simple structure that can quickly realize the disassembly and assembly of the triangular seat. By pulling the guide rod 4 outward and rotating the guide rod 4, the pressure plate 5 can be moved away from the opening of the U-shaped positioning plate 3, so that the triangular seat can be easily taken out and installed. Conversely, after the triangular seat is installed into the mold opening of the U-shaped positioning plate 3, the guide rod 4 is pulled outward and selected, so that the pressure plate 5 presses the triangular seat under the action of the repulsive component, ensuring that the positions of all the triangular seats on the base 1 are consistent, thereby improving the calibration accuracy.
