Intelligent warp-knitting-machine needle-bed headstock speed-range variable motion system

Abstract

Disclosed is an intelligent warp-knitting-machine needle-bed headstock speed-range variable motion system which comprises a variable speed motor, a rotating shaft and a needle bed plunger cap. The variable speed motor drives the rotating shaft, the needle bed plunger cap is mounted on the extension end of the rotating shaft through a radial regulating device, and the needle bed plunger cap is radially adjustable along the rotating shaft. Output of kinetic energy is achieved in the motion mode that the variable speed motor drives an eccentric wheel with adjustable eccentric distance to move, sothat traveling trajectory of a needle bed swinging cam of a warp knitting machine is flexibly variable; driving on a plunger does not rely on the travelling cam, so that the plunger does not contactwith the cam directly; lateral force does not exist since the plunger is only subjected to axial force, motion resistance is greatly lowered, abrasion of the plunger is avoided, a plunger driving mechanism does not need to be dipped in an oil groove, and the problem about lubricant pollution commonly existing in the warp knitting machine is solved.

Description

technical field [0001] The invention relates to the field of warp knitting machines, in particular to a motion control system for simulating a main shaft of a warp knitting machine. Background technique [0002] The warp knitting machine is a textile equipment for special fabrics. In the warp knitting machine, the swing of each needle bed is driven by a cam with a specific shape to change the lifting speed of the tappet. Different specifications of patterns need corresponding cams to adjust the speed of the tappet. Realization, due to the ever-changing specifications and shapes of lace cloth, in order to meet the production needs, it is not only necessary to be equipped with many specifications of cams, but also to manually replace them, which not only increases the production cost, but also directly affects the effective working time of the warp knitting machine. In recent years, the applicant has been researching the swing mechanism of the needle bed of the warp knitting m...

Problems solved by technology

[0002] The warp knitting machine is a textile equipment for special fabrics. In the warp knitting machine, the swing of each needle bed is driven by a cam with a specific shape line to change the lifting speed of the tappet. The patterns of different specifications need corresponding cams. Realization, due to the ever-changing specifications and shapes of lace cloth, in order to meet the production needs, it is not only necessary to equip cams of many specifications, but also to replace them manually, which not only increases the production cost, but also directly affects the effective working time of the warp knitting machine

In recent years, the applicant has been researching the swing mechanism of the needle bed of the warp knitting machine, and changed the purely mechanical drive system of the needle bed of the warp knitting machine into an intelligent electronically controlled digital drive system, so that the advanced electronic control technology can be obtained on the warp knitting machine. At present, the upper needle bed of the warp knitting machine is driven by a motor, and the cam with a specific line type on the main shaft drives the push rod of the needle bed to realize the swing of the needle bed. This is a purely mechanical drive driven by a traditional AC motor. The movement mode of the needle bed has the problems that the speed and amplitude of the ejector rod cannot be adjusted, and the specific cam needs to be replaced when changing the weaving type, which requires a long auxiliary time, complex movement mechanism and high cost.
