ROUND KNITTING MACHINE OF SMALL DIAMETER

The utility model relates to the field of knitting engineering, namely to small diameter circular knitting machines for the manufacture of cords.

Known circular knitting machine (A.S. No. 1516542, MKI D 04 B 9/44, 1989) for producing plush small diameter tubes containing a needle cylinder equipped with reed needles and fixed locks.

A small-diameter circular knitting machine is known (A.S. JV 490181, MKI D 04 B 9/44, 1989), containing a stationary cylinder, in the grooves of which reed needles are installed, the resulting; non-return movement from lock wedges.

The disadvantage of these mechanisms is that the loads are perpendicular; those in the loop-forming system of the knitting machine are the main cause of intense wear and destruction of needle-platinum products and wedges; they lead to failures of the knitting mechanism, and are also a constraining factor in increasing the productivity of knitting machines.

The objective of the utility model is to eliminate this drawback and increase the speed of movement of the needles, as well as to increase the reliability of the looping operation.

The problem is solved in that an individual electromagnetic drive is installed on each needle, consisting of a pusher connected to the core of the electromagnet, electromagnet, spring and viscoelastic elements.

Figure 1 schematically shows a circular knitting machine of small diameter with an electromagnetic drive of loop-forming organs.

A small diameter circular knitting machine (Fig. 1) for the manufacture of a knitted cord comprises a fixed cylinder 1 mounted on a frame 2, in the grooves of which reed needles 3 are mounted, resulting in a reciprocating movement from the pusher 4, spring-loaded 5 and connected to the core 6 of the electromagnet 7 The electromagnets 7 are mounted on a support 8. A thread guide 9 is installed above the cylinder 1, feed a thread from the bobbin 10 to the needles 3, driven by an electric motor 11. Viscoelastic limiters 13, 14, 15 are installed in the housing 12.

The machine works as follows: im way.

When applying an electric signal to the electromagnet 7, the core 6 retracts, the pusher 4, variable upward, connected to the needle 3. At the same time, the signal is applied to the electric motor And the thread is laid on the needle 3. To lower the needle 3, the current to the electromagnet 7 ceases to be supplied and the spring 5 is activated , core 6 returns to its initial position, lowering the needle 3. To turn off the needle 3 from work, no current is supplied to the coil of the electromagnet 7 and the needle does not knit. Knitting the cord occurs by sequentially turning on the electromagnets.

To increase the reliability of the process of loop formation and damping of possible oscillations of the needle 3, the knitting mechanism is equipped with: viscoelastic elements 13, 14, 15.
