SU30792A1 - Device for turning off the loop-forming system on a knitting males machine when the thread breaks - Google Patents

Description

The proposed device is intended for knitted menis machines having more than one maléza, and aims to eliminate the disadvantage of stopping all maschiny when any thread breaks. This device automatically turns off only the malezu (system) on which the thread breaks, without causing the machine to stop, with the continuation of the work of other systems (malez).

In FIG. 1 is a side view of the device; figs. 2 and 3, respectively, view along arrows A and S of parts of the device shown in fig. one; FIG. 4-detailed view of the cutting device.

The device consists of three devices that work together: 1) a cutting device for the threads needed to refill the Malaise in, several threads, 2) the already well-known blender that turns off the press wheel and 3) a cleaning device for the hooks of the needles.

The cutting device designed to cut one of the filled threads when the break is broken consists (Fig. 4) of the known lamellar knives / laid one on top of the other, with slots 2 for the passage of the threads. One of the blade knives / fixedly fastened with a screw 3 to the thread guide bar (35)

a pad, the other one is fastened with screws 4 and during movement overlaps the slots 2. The knives are actuated due to pressing on the edge 5 of the movable knife of the beveled part of the protrusion 6 fixed on the shoulder of the rotary lever 7 thread suppressor.

The already known device for turning off the press wheel by lifting it is necessary to eliminate unnecessary pressure on the hooks of the needles caused by a change in the position of the latter, due to the cessation of the deflection due to the absence of thread. The mechanism consists (Fig. 1, 3) of the angular lever S with an eye 9 and a sloping part / 0. The lever 8 is movably secured with a screw // to the rack / 2 presses. By the action of the bevelled part W of the lever 8 from the gigi / 5, the press bar J4 moves to the side, which serves as a stop for the screw / 5 of the rocker arm J6 with the press wheel / 7. Under the action of the spring / left part of the rocker arm J6 lowers, lift the right side with the press wheel / 7. Installing the press wheel 77 to the working position is performed by lifting the rocker arm J6 by the handle 7P. To prevent possible waste of the press 20, a fuse 27 is used, fastened with a screw to the press block 22 of the press 20.

A needle cleaner for picking needles serves to select
