Abstract
Description
Technical Field
[0001] This utility model belongs to the field of textile machinery, and specifically relates to an integrated piezoelectric jacquard device for warp knitting machines. Background Technology
[0002] In the warp knitting textile industry, the common practice for computerized jacquard machines is to use computer-controlled piezoelectric jacquard devices for weaving. As patterns become increasingly complex, the number of jacquards used in warp knitting machines is also increasing. A schematic diagram of an existing piezoelectric jacquard device is shown below. Figure 1 As shown, it consists of an existing base 1, needle selection plate 2, potting compound 3, protective cover assembly 4, cable bundle assembly 5, and plug assembly 6. Currently, the requirements for jacquard weave on warp knitting machines are becoming increasingly stringent, with more and more complex patterns, leading to the increasing adoption of the dual piezoelectric jacquard device installation structure on warp knitting machines. Figure 2 This existing piezoelectric jacquard device consists of four sets of existing piezoelectric jacquard devices 12, four sets of guide bars 9, yarn guide plates 7, yarn guide plate fixing screws 8, etc. The fan-shaped angle of the yarns 10 on both sides is about 88°, which makes the installation fan-shaped angle of the entire warp knitting machine too large, and cannot improve the running speed of the warp knitting machine.
[0003] In Patent Document 1, the patentee proposed a piezoelectric Jacquard device 2 14 for a warp knitting machine, which uses two sets of piezoelectric Jacquard devices 2 14 installed on the comb bar 2 17, with the installation fan-shaped angle between the yarns 10 being approximately 64°. Figure 3 , Figure 4 , Figure 5 This greatly optimizes the installation angle of the piezoelectric jacquard device. However, in the structure of Patent Document 1, the number of double-sided bases and double-sided needle selectors is greatly increased, resulting in a large number of plug assemblies and cable assemblies, which makes it difficult for the yarn to be threaded and passed through the warp knitting machine.
