Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of warp knitting machines, in particular to a convenient adjustment of the guide bar transverse movement mechanism. BACKGROUND

[0002] The warp knitting machine is a kind of weaving equipment that uses one or more groups of parallel yarns to be fed from the machine in the warp direction and to form loops on all the working needles to form a knitted fabric. The warp knitting machine mainly consists of a knitting mechanism, a guide bar transverse movement mechanism, a warp feeding mechanism, a pulling and winding mechanism, and a transmission mechanism. Among them, the guide bar transverse movement mechanism is to move the guide bar transversely according to the requirements of the knitted fabric structure during the loop forming process, so as to pad the warp yarns on the needles, so as to weave the knitted fabric with a certain structure.

[0003] In the related art, a guide bar transverse movement mechanism is disclosed, which includes a cam rotatably connected with a frame, a push rod slidably connected with the frame in the transverse direction of the frame, and a pulling rope connected with the guide bar. One end of the push rod is connected with the guide bar, and the other end is in contact with the peripheral wall of the cam. The end of the pulling rope away from the guide bar is connected with a tension spring, and the tension spring is connected with the frame. The tension spring is in a stretched state to keep the push rod in contact with the peripheral wall of the cam. The frame is provided with a motor for driving the cam to rotate, so that the push rod moves relative to the peripheral wall of the cam, and the push rod moves transversely relative to the frame to push the guide bar, so that the guide bar moves transversely. The tension spring cooperates with the pulling rope to reset the guide bar. The surface texture of the knitted fabric woven by the warp knitting machine is related to the frequency and amplitude of the guide bar transverse movement. Different guide bar transverse movement frequencies or amplitudes can make the surface texture of the knitted fabric different.

[0004] For the related art in the above, the inventors believe that when the surface texture of the knitted fabric needs to be changed, the corresponding cam needs to be removed, and then the cam corresponding to the required surface texture needs to be installed. The operation is relatively cumbersome, and therefore needs to be improved. SUMMARY
