Abstract

The invention relates to the knit machine industry, in particular to the pattern-forming devices of the Komets-type blanket machines, and allows the machine to expand its technological capabilities by providing a tackle, cloth, satin into the weave of a continuous soil web. To do this, two additional gears 13, 14 are installed on both shafts 1 and 2, one of them — gear 13 — is fixed rigidly on the low-speed shaft 2, and the other gear 14 is mounted on the high-speed shaft 1 for free rotation, the latter being rigidly connected to patterned fist 15, interacting with a dirt comb 19. 7 Il.

The invention relates to the knitting machine building industry, in particular, to the pattern-forming device of the bases — hall machines, mainly knitting machines of the Komets type.

The purpose of the invention is the expansion of the technological capabilities of a wafering machine by improving the mechanism of pattern formation, which ensures that the continuous ground canvas is interwoven with tights, cloth, and las.

FIG. 1 shows the mechanism, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 - tricot weave; in fig. 4 - The structure of the intertwining of the basics of knit tricot with weft; in fig. 5 and 6 are the profiles of the patterned fists, which provide a tric or cloth strip of the thread on the needles to the soil comb; in fig. 7 is a diagram of the loop formation process.

The patterning mechanism contains high-speed 1 and low-speed 2 shafts connected by gears 3 and 4 with a gear ratio i 1: 2, which provides the low-speed shaft with a rotation speed of half the speed of the high-speed shaft. A patterned fist 5 is fixed on the shaft 1, which provides vertical raising and lowering of the weft combs 6 relative to the tongue needles 7, and patterned fists 8 and 9 are rigidly fixed on the shaft 2, which through the levers 10 and 11 provide a horizontal shift of the weft combs 6 Cell machines have a large number of weft combs (up to 8), which are shifted by a patterned drum on which chains with dies are put on (not shown). The gear 13 is rigidly fixed on the low-speed shaft 2 by means of locking bolts 12 (Fig. 2), and the gear 14 is rigidly attached to the patterned fist 15 on the high-speed shaft 1 with the possibility of free rotation relative to it. The gears 13 and 14 have the same number of teeth, which ensures rotation of the cam 15 at the same speed as the cam 8 and 9. The gear 14 and cam 15 are separated from the shaft 1 by the sleeve 16 (FIG. 2) of antifriction material (for example, bronze), and the longitudinal gear shift 14 with fist 15 relatively

shaft 1 is limited by retaining rings 17. Fist 15 interacts with lever 18 of a dirt comb

19 and provides her with laying of ground threads on the tongue needles for weaving in the weaves of tights, cloth

etc. due to the corresponding profile (Fig. 5 and 6).

The patterning mechanism receives movement from the central shaft 20, which is associated with shaft 1 by a pair of identical bevel gears 21. Shaft

20 kinematic are associated with tongue needles 7 (connection not shown) and an earth comb 19 and provides

her tangential movement through the crank 22, the connecting rod 23 and the rocker 24. The housing 25 of the mechanism (its elements) in FIG. 1 and 2 is shown conditionally. On the soil ridge 19 mounted tiles with lug needles 27, and on the patterned weft comb - tubular yarn guide 26.

The patterning mechanism works as follows.

The rotation of the shaft 20 informs the reciprocating movement of the tongue needles 7; tangential movements of the dirt comb through crank 22, connecting rod 23 and rocker 24; rotating the patterned cam 15 through a pair of bevel gears 21, a first pair of cylindrical gears 3 and 4 and a second pair of cylindrical gears 13 and 14.

For one complete rotation of the shaft 20, the tongue needles 7 complete lift and lower; weft combs 6 perform a full raising and lowering from the fist 5 and one shift from the fists 8 and 9, laying the weft threads behind the backs of the needles 7 (Fig. 7); the soil comb 19 makes a complete swing from the lower position to the upper one and vice versa, pumping the eye needles 27 between the tongue needles 7 (Fig. 7); The fist 15 performs the first half of the revolution and provides the first shear needle needles 27 above the tongue needles 7, spreading ground threads on them, and a second shift behind the backs of the needles 7 to prepare for laying the ground threads on the adjacent tongue needles. Thus, in one revolution of the shaft 20 (or one half of the rotation of the shaft 2), one complete loop of the loop is performed. During the subsequent looping cycle

The fist 15 performs the second half of the rotation, providing the third shear of needle needles 27 under the adjacent tongue needles and the fourth shift behind the backs of the needles 7.

If it is necessary to replace the soil weave, the fist 15 is replaced with the gear 14, which can be made in one piece (as shown in Fig. 2).

Reducing the speed of rotation of the fist 15 by half; in comparison with the fist 1, which is rigidly mounted on a shaft and which provides only the basics of a closed chain, it is possible to allow unpaved
