Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a warp knitting machine with an adjustable axial position of a sinking swing shaft. Background Art

[0002] During the operation of the warp knitting machine, the sinking mechanism is a key component, which is responsible for controlling the yarn looping process. In the traditional sinking mechanism, the axial position of the sinking swing shaft is fixed, and one end of the sinking swing shaft is connected to the warp knitting machine frame. The sinking swing shaft can produce a small angle of swing, but it is positioned in the axial direction, which makes it impossible to conveniently adjust the needle positions of the sinking bed and the groove needle bed in the axial direction. That is, when the temperature environment changes, the sinking bed and the groove needle bed will produce axial offset from each other, and this offset is sometimes enough to affect the weaving accuracy. For this traditional fixing method, a large number of connectors need to be disassembled to adjust the axial position of the sinking swing shaft, which is not only time-consuming and labor-intensive, but may also affect the looping movement of the yarn.
