Wire drawing and feeding device for lifting bottom plate
Technical Field
The invention relates to the technical field of computerized flat knitting machines, in particular to a starting plate wire drawing and feeding device.
Background
The computerized flat knitting machine is a double-needle plate latch needle weft knitting machine, its cam device is like a group of plane cams, the stitch of the knitting needle can be fed into the channel of the cam, the cam can be moved, the knitting needle can be forced to make regular lifting movement in the needle channel of the needle plate, and the yarn can be knitted into knitted fabric by means of the action of needle hook and needle latch. In the ascending process of the knitting needle, the coil gradually withdraws from the needle hook, the needle latch is opened, and the withdrawing needle latch is hung on the needle rod; during the descending process of the knitting needle, the needle hook hooks the newly laid yarn and draws and bends the newly laid yarn into a coil, meanwhile, the original coil is separated from the needle hook, the new coil passes through the old coil and is connected with the old coil in series, and the coil strings knitted by a plurality of knitting needles are mutually connected to form the knitted fabric.
At present, a stepping motor is adopted by a bottom-starting wire drawing device of a computerized flat knitting machine to rotate, a wire drawing gear set is driven to rotate, and the clamping force of a gear is used for pulling a steel wire to move so as to realize wire feeding and wire drawing of the steel wire. The bottom-lifting spinning device can achieve the spinning effect, but in practical application, the problem that the friction force between the steel wire and the yarn is too large to exceed the friction force between the gear and the steel wire and the spinning cannot be drawn out exists. Causing the friction between the wire drawing gear and the steel wire for a long time to break the steel wire.
