Description

Technical Field

[0001] The utility model relates to a warp knitting machine, in particular to a connection structure between a hanger and a connecting rod of the warp knitting machine. Background Art

[0002] At present, the connection structure between the comb hanger and the connecting rod of the warp knitting machine is as follows: Figure 1 and Figure 2 As shown, the connecting rod 1' is detachably connected to a connecting block 2', and the connecting block 2' is movably mounted on the rotating shaft 4' through a bearing 3', and the hanger 5' is bolted to the rotating shaft 4'. The connecting block 2' and the rotating shaft 4' connect the connecting rod 1' and the hanger 5' into one. When the machine is stopped to take and place the comb bar 10', the connecting rod needs to be rotated upward to an angle that will not interfere with the taking and placing of the comb bar. Since the connecting block and connecting rod assembly cannot stay at this angle under the action of bearings and gravity, and there are multiple sets of hangers for the warp knitting machine, it is necessary to manually lift the comb bar with multiple hands, which is time-consuming and labor-intensive. In view of this, it is urgent to improve the connection structure of the comb bar hanger and the connecting rod of the warp knitting machine to improve the work efficiency when taking and placing the comb bar. Utility Model Content

[0003] The utility model aims to provide a connection structure between a warp knitting machine hanger and a connecting rod.

[0004] The technical solution for achieving the purpose of the utility model is: a connection structure between a hanger and a connecting rod of a warp knitting machine, which includes a connecting rod, a hanger, a rotating shaft and a connecting block, the hanger and the rotating shaft are connected by bolts, a limiting block is arranged on the side of the rotating shaft away from the hanger, the bolt passes through the limiting block and the rotating shaft from the front side of the limiting block and is threadedly connected to the hanger; the connecting rod has a fixed end, the end surface of the fixed end is provided with a threaded groove, a ball screw is screwed and fixed in the groove, and a first Together with the cap nut, the connecting block is "U"-shaped, the connecting block includes two support arms and a connecting part connecting the two support arms, the fixed end of the connecting rod is detachably connected to the connecting part, the two support arms are movably installed on the rotating shaft on both sides of the hanger through bearings, and a serrated groove is provided on the side of the limit block; the position of the groove is such that there is a movable gap between the connecting rod and the limit block when the connecting rod is working, and the ball screw is engaged with the groove when the connecting rod is rotated to an angle that does not interfere with the taking and placing of the comb.

[0005] Furthermore, the fixed end is threadedly connected to the connecting portion, and a second cap nut is threadedly connected to the fixed end.

[0006] Furthermore, an arc-shaped groove that fits the rotating shaft is provided on the back side of the limiting block.

[0007] The connection structure of the warp knitting machine hanger and the connecting rod realized by the utility model adds a ball screw to the fixed end of the connecting rod, and installs a limit block with a serrated groove on the rotating shaft, so that when the connecting rod is rotated to an angle that does not interfere with the taking and placing of the comb bar, the ball screw engages with the groove, thereby eliminating the need for manual lifting of the connecting rod, saving time and effort and improving work efficiency.
