Description

Technical Field

[0001] The utility model relates to the technical field of warp knitting machines, in particular to a warp knitting machine with a limiting mechanism. Background Art

[0002] A warp knitting machine is a machine used to weave fabrics. Its main function is to form a knitted fabric by simultaneously looping one or several groups of parallel yarns on all the working needles of the machine fed in the warp direction.

[0003] The warp knitted fabrics produced by the warp knitting machine usually need to be rolled into a tube. Different winding rollers need to be replaced when winding fabrics of different lengths. Some winding rollers are limited at both ends by a limiting structure so that fabrics of different lengths can be wound. The existing limiting structure consists of two adjustable limiting plates. After the position of the limiting plate is adjusted, its bolts need to be locked. After each winding, if the bolts are not loosened, the removal of the tubular fabric will be limited by the space of the limiting plate, which makes it inconvenient to take it. If the bolts are loosened, the subsequent winding requires resetting the position of the limiting plate and then tightening the bolts. The operation process is relatively cumbersome.

[0023] In addition, the limiting component 6 includes an upper limiting arc ring 61 and a lower limiting arc ring 62. The upper limiting arc ring 61 and the lower limiting arc ring 62 on the side close to the splicing surface are both provided with arc-shaped through holes in the middle, and the lower limiting arc ring 62 on the side close to the splicing surface is provided with two clamping components at equal distances at both ends of the through holes.

[0024] At the same time, the clamping assembly includes a fixed ring seat 63, and the outer wall of the fixed ring seat 63 is movably sleeved with movable rings at equal distances, and a movable clamping block 64 is installed on one side of the movable ring.

[0025] In addition, a clamping groove is provided on the fixed ring seat 63 on one side of the upper limit arc ring 61 close to the splicing surface, and a movable cavity is provided in the movable clamping block 64 in the upper limit arc ring 61, and a limit clamping block 65 is inserted into the movable cavity.

[0027] In addition, a T-shaped fixing block 611 is installed in the middle of the top of the upper limit arc ring 61, and an inlet and outlet slot is opened on one side of the fixing block 5 at the T-shaped fixing block 611, and a placement cavity is opened in the fixing block 5 below the inlet and outlet slot.

[0028] At the same time, the bidirectional screw drive assembly 7 includes a bidirectional screw body, which is driven by a drive motor, and two nut pairs are symmetrically arranged on the outside of the bidirectional screw body, and the bottom of the nut pair passes through the mounting frame 4 and is connected to the fixed block 5.

[0030] At the same time, it is worth mentioning that when the movable block 64 rotates to a vertical state with the bidirectional screw body assembly 7, the through hole of the movable block 64 is aligned with the slot of the upper limit arc ring 61, and then the movable block 64 can be limited by the limit block 65.
