Abstract

The invention relates to a control device for a knitting technology of a double needle bar machine and a control method of the control device. The control device comprises a complete machine integrated control unit, two code controllers and a transverse moving drive execution unit, wherein the two code controllers are mounted on a main shaft of the double needle bar machine; the complete machine integrated control unit comprises an industrial personal computer, a PLC and an intelligent transverse moving controller; two communication output ends of the industrial personal computer are respectively and electrically connected with a signal collection port of the PLC and a signal input end of the intelligent transverse moving controller; the transverse moving drive execution unit comprises at least six servosystems, reduction gearboxes, electric cylinder movement devices and a transverse moving mechanism; the quantity of the servosystems is the same as those of the reduction gearboxes and the electric cylinder movement devices; each servosystem comprises a servo driver and a servo motor; the transverse moving mechanism comprises a machine frame and at least six transverse moving rod movably connected to the machine frame. The control device and the control method have the advantages that the structure is simple, the operation is stable and reliable, the pattern replacement is facilitated, the guide bar transverse movement can be controlled independently, the transformation angle is larger, the equipment speed is increased, the cloth cover weaving effect is improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of electrical development and control of a warp knitting machine, in particular to a control device and a control method for the knitting process of a double-needle bed warp knitting machine. Background technique [0002] At present, the knitting process control devices of most of the existing double-needle-bed warp knitting machines are basically mechanical chain blocks and raised disc structures. As early as 1774, the British invented the mechanical chain block control structure. The technology is mature, and the operation is stable and reliable, but this form has complex structure, long maintenance cycle, difficult pattern replacement, slow machine operation speed, high operation noise, and large floor space.

Problems solved by technology

[0002] At present, the knitting process control devices of most of the existing double-needle bed warp knitting machines are basically mechanical chain blocks and convex disc structures. As early as 1774, the British invented the mechanical chain block control structure. The technology is mature, the operation is stable and reliable, but this form has complex structure, long maintenance cycle, difficult to replace the pattern, slow machine running speed, loud running noise and large floor space

The convex plate structure occupies a small area and is easy to use, but the convex plate is easy to wear after long-term use. When changing the pattern, the original convex structure must be removed, which is cumbersome and cannot improve production efficiency.

It is difficult to change the pattern of the double-needle-bed warp knitting machine with mechanical chain block and convex disc structure. The electronic traverse control of the double-needle-bed warp knitting machine is all from bar 1 to bar 6 after the traverse is completed. It is called a traversing cycle, that is to say, when the left and right needle beds are not hooked, only a few bars can make traversing movement, which limits the machine and bar traversing speed, slow production and low production efficiency
