The eccentric connecting rod is stable in transmission, simple and convenient to process and low in abrasion and noise during high-speed operation, so that the eccentric connecting rod is widely applied to a high-speed warp knitting machine.
The existing warp knitting machine needle bed usually adopts aluminum magnesium alloy section bar, then uses milling machine to process several needle grooves according to the set distance, although the aluminum magnesium alloy is light, theoretically can raise its rotating speed, in the course of actual use, the aluminum magnesium alloy is easy to deform, its thermal expansion coefficient is higher, its expansion with heat and contraction with cold are more obvious, and it is greatly influenced by environmental temperature, not only can not raise its complete machine rotating speed, but also has influence on the stability of the machine, and is easy to cause the condition of needle-punching, etc., and can greatly reduce the quality of weaving.
In order to further reduce the mass of a needle bed, improve the rigidity and the strength of the needle bed and improve the rotating speed of a knocking-over needle bed, the knocking-over needle bed of a warp knitting machine is made of a mixed fiber material, and the knocking-over needle bed is designed to be of a hollow structure at the middle part.
As patent numbers: the needle bed manufacturing method disclosed in ZL200820040684.8 is of a solid structure like most of existing needle beds, and the needle bed substrate is a carbon fiber needle bed substrate, but the price of carbon fiber is higher than that of hybrid fiber, the batch production cost is higher, and the popularization and application are not convenient under the condition of the same performance.
Meanwhile, the hollow needle bed base body structure is superior to a solid needle bed base body in the aspects of rigidity, strength and the like, so that the operation speed and the operation stability of the needle bed are improved, and the production efficiency is greatly improved.
