Shogging mechanism with double push rod

Abstract

The invention relates to a swaying mechanism of a warp loom, in particular to a stripping comb swaying device provided with double push rods. The invention provides a technical proposal that a ball screw is arranged on a machine frame, and the technical proposal is characterized in that two ends of the ball screw are respectively arranged on the machine frame through bearings, a feed screw nut ismatched and connected with the ball screw, a fitting seat is arranged on the feed screw nut and is connected with the right end of the push rod, the left end of the push rod is connected with the machine frame in a sliding way, and an axes of the push rod is parallel to an axes of the ball screw. The stripping comb swaying mechanism can adopt the driving of a rotary actuating motor, is used for the swaying of ground combs of the warp looms at moderate or low speed, and has the advantage of the driving of the double throwout levers without shearing force.

Description

technical field [0001] The invention relates to a traversing mechanism on a warp knitting machine, in particular to a bar traversing device with double push rods. Background technique [0002] The traditional multi-bar warp knitting machine's ground comb or jacquard comb's traverse device mostly adopts mechanical transmission, and the pattern carrier adopts chain blocks or faceplates. This mechanically driven traverse device has disadvantages such as small traverse distance, large impact, small pattern cycle, and inconvenient pattern change. [0003] Recently, there is also an electronic traversing device controlled by a rotary servo motor on the warp knitting machine. This device mainly consists of a servo motor, a ball screw, a screw nut and a sliding guide rod. However, there are still many problems in use, such as: (1) The position of the ball screw is not fixed well, which affects the accuracy of the horizontal movement of the bar; (2) The guide rod is not designed or ...

AI Technical Summary

Problems solved by technology

A thrust bearing is installed at one end to fix the lead screw. It is difficult to locate the axial direction during installation, and gaps are likely to occur, thereby reducing the accuracy of the horizontal movement of the bar; one end of the lead screw is similar to sliding positioning, which will produce sliding damping during operation and cause the ball screw to vibrate slightly. , which not only affects the accuracy of the system but also reduces the service life of the mechanism; the guide rod is not designed or the design of the guide rod is not ideal, which affects the structural rationality of the entire mechanism
