Description

Technical Field

[0001] The utility model relates to the field of warp knitting machines, in particular to a new type of segmented groove sinking and swinging shaft structure of a warp knitting machine. Background Art

[0002] A knitted fabric is formed by simultaneously forming loops on all the working needles of the warp-feeding machine using one or several groups of parallel arranged yarns. This method is called warp knitting, the fabric is called warp knitted fabric, and the machine that completes this warp knitting is called a warp knitting machine. The warp knitting machine's groove sinker and pendulum shaft is a segmented structural device in the wall panel, which refers to the swing device that makes the groove needles, comb bar pendulum shaft components, and sinker pendulum shaft components produce a swing under the motion of the loop-forming crankshaft.

[0003] As the width of existing warp knitting machines increases, the slot sinking and swinging shafts of warp knitting machines also increase. Warp knitting machines are assembled from various materials, such as the comb swinging shaft is steel, the comb is a carbon fiber needle bed, and the swing arm is aluminum. The different thermal expansions produced by various materials during high-speed operation of the warp knitting machine seriously threaten the needle spacing of the knitting needles. To solve this problem, the only way is to improve the design and add a protective device to eliminate the thermal expansion effect. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new type of segmented groove-sunk swing shaft structure of a warp knitting machine, including a small wall panel, an outer ring is installed inside the small wall panel, a roller groove is opened on the inner wall of the outer ring, and there are multiple roller grooves, and rollers are installed inside the multiple roller grooves, a shaft sleeve is installed inside the outer ring, the outer wall of the shaft sleeve is tightly fitted with the multiple rollers, a swing shaft is installed inside the shaft sleeve, and there are two swing shafts, key grooves are opened on the opposite surfaces of the two swing shafts, and a connecting key is installed inside the key groove, the outer walls of the two swing shafts are sleeved with clamping rings, and oil seals are provided at both ends of the outer ring, and the oil seal is located in the interlayer between the outer ring and the clamping ring.

[0006] An oil inlet is formed on the outer wall of the small wall plate, and a connecting hole is formed on the outer wall of the outer ring. The position of the connecting hole corresponds to the position of the oil inlet.

[0007] The inner wall of the oil inlet is threadedly connected with a sealing cover, and one end of the sealing cover extends to the inside of the communicating hole.

[0008] The ends of the two shaft sleeves facing away from each other are both provided with hollow grooves, and the number of the hollow grooves is multiple.

[0009] The bottom of the small wall panel is fixedly connected with a bracket, and the bottom of the bracket is fixedly connected with a base.

[0010] The base is provided with two positioning holes inside.

[0011] The utility model has the following beneficial effects:

[0012] 1. Compared with the prior art, the segmented slot-sinking swing shaft structure of the novel warp knitting machine utilizes a connecting key to connect the two swing shafts, so that the two swing shafts are fixed in sections in the wall panel, thereby preventing the thermal expansion effect generated by various materials during the high-speed operation of the warp knitting machine from causing extrusion and deformation between components, thereby improving the reliability of the warp knitting machine and increasing the safety performance of the machine. As the width of the existing warp knitting machine increases, the slot-sinking swing shaft of the warp knitting machine is also lengthened. The warp knitting machine is assembled from various materials, such as the comb bar swing shaft is a steel part, the comb bar is a carbon fiber needle bed, and the swing arm is an aluminum part. The different thermal expansions generated by various materials during the high-speed operation of the warp knitting machine seriously threaten the needle pitch of the knitting needles. The device effectively avoids the thermal expansion effect generated by various materials during the high-speed operation of the warp knitting machine from causing extrusion and deformation between components, thereby improving the reliability of the warp knitting machine and increasing the safety performance of the machine.
