Background

In the warp knitting machine textile industry, at present, a common method of a computer jacquard machine is to weave by using a piezoelectric jacquard device controlled by a computer, and with the increasingly complex pattern, the jacquard quantity used by the warp knitting machine is also increasing.

The main reasons influencing the installation sector angle of the piezoelectric jacquard device are as follows: 1) the front tooth supporting cantilever beam with the hook of the magnesium alloy has too thick size due to low strength of the magnesium alloy, and the installation angle is influenced; 2) the front tooth support cantilever part with the hook of the existing base is not wear-resistant and must be provided with a yarn passing plate for passing yarn; 3) the front tooth with a hook on the base of the existing piezoelectric jacquard device influences the installation fan-shaped angle; 4) the positions of the inflection points of the bevel edges of the clamping sleeves of the existing yarn guide needles are not right, so that the installation fan-shaped angle is influenced. The above situation causes the installation fan-shaped angle of the piezoelectric jacquard device to be increased, and the equipment speed cannot be improved.
