Yarn pressing plate movement device of warp knitting machine

Abstract

The invention discloses a yarn pressing plate movement device of a warp knitting machine. The device comprises a yarn pressing plate and an oil tank spindle, wherein an eccentric wheel, an eccentric sleeve connecting rod, a lower swing rod, an output rod, a middle swing rod, a support rod, a first yarn pressing connecting rod, a second yarn pressing connecting rod and an upper swing rod are arranged between the yarn pressing plate and the oil tank spindle; the lower end of the eccentric sleeve connecting rod is sleeved on the eccentric wheel; the upper end of the eccentric sleeve connecting rod is connected with one end of the lower swing rod and the lower end of the output rod in a rotating mode; the other end of the lower swing rod is arranged on a frame in a rotating mode; the upper end of the output rod is connected with a body of the middle swing rod in a rotating mode; one end of the middle swing rod is connected with the lower end of the support rod in a rotating mode; the other end of the middle swing rod is arranged on a looping swing shaft in a rotating mode; the upper end of the support rod is connected with one end of the first yarn pressing connecting rod in a rotating mode; the other end of the first yarn pressing connecting rod is connected with the upper end of the second yarn pressing connecting rod in a rotating mode; a body of the first yarn pressing connecting rod is arranged on the frame in a rotating mode; one end of the upper swing rod is connected with a body of the second yarn pressing connecting rod in a rotating mode; and the other end of the upper swing rod is arranged on the frame in a rotating mode. The device can meet the process requirement of the warp knitting machine with a few guide bars on same-direction yarn laying and pressing, and can adapt to high-speed knitting.

Description

technical field [0001] The invention relates to a knitting mechanism of a warp knitting machine, in particular to a yarn pressing plate moving device in the knitting mechanism of a warp knitting machine with fewer than 18 pressing bars. Background technique [0002] The yarn pressing plate moving device of the existing pressing type warp knitting machine, such as Chinese invention patent ZL200810156904.8, is called a structure disclosed in the open specification of the warp knitting machine pressing plate moving device, which includes the warp knitting machine The oil tank main shaft and the yarn pressing plate, the oil tank main shaft drives the yarn pressing plate to move through two or more identical transmission mechanisms, and each set of transmission mechanisms consists of a conjugate cam mechanism, a first plane hinge four-bar mechanism, a second plane hinge The four-bar mechanism and the slider mechanism are connected in series. With this structure of the yarn press...

AI Technical Summary

Problems solved by technology

This kind of yarn pressing board moving device has the following two disadvantages. On the one hand, because the whole moving device is driven by the main shaft of the oil tank through the synchronous belt, the transmission efficiency is low; on the other hand, the yarn pressing board moving device of this structure Also can not meet the same direction lap yarn process requirement of less carding warp knitting machine, so this device also can't be used on less carding warp knitting machine
