Description

Probe of computerized flat knitting machine

Technical Field

The utility model relates to a computerized flat knitting machine technical field, in particular to computerized flat knitting machine probe apparatus.

Background

The knitting machinery equipment mainly comprises a flat knitting machine, a hosiery knitting machine, a warp knitting machine and a circular knitting machine. The flat knitting machine is mainly used for producing knitted products such as sweaters, knitted shoe uppers and the like, and comprises a hand flat knitting machine, a semi-automatic flat knitting machine and a computerized flat knitting machine according to the development of the flat knitting machine. The computerized flat knitting machine is a double-needle plate latch needle weft knitting loom. 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.

The computerized flat knitting machine has a probe for detecting float in knitting area, and the position of the probe is changed to drive the inductive switch. The traditional microswitch type probe can be reset within a certain range, but the reset range is small, and the slightly larger collision can cause the swing range of the probe piece to exceed the reset range, so that the probe piece cannot be automatically reset. Due to the fact that the operation space of the probe piece is narrow, when the probe piece operates outside a weaving area, the probe piece can be contacted with objects such as yarns and yarn nozzles, the probe is prone to exceeding the reset range and being in an alarm state all the time, and therefore trouble-free parking is caused. Therefore, the machine is often stopped and the probe sheet is manually reset, so that the working efficiency is low.
