Description

 and 2) needle

The invention relates to a knitted garment design, i.e., to a circle of fishing machines for the automatic production of grains, which are used for sewing upper or linen knitted goods.

The aim of the invention is to improve the accuracy of the depth control.

FIG. 1 shows a block with wedges for moving the needles of the cylinder, front view; FIG. 2 shows section A-A in FIG. 1 | in fig. 3 shows a section BB in FIG. 1J in FIG. 4 shows a section B-B in FIG. 3 (roller with the profile of the cam).

In block 1 (Fig. Cylinder (not shown) in the hole

3. A spring 4, installed in the opening 5 of the block 1, with the upper end 6 enters the recess 7 of the lower end 8 of the slide 3, pressing it upwards. At the upper end 9 of the slider, a special adjustable screw 10 with a lock nut 1 1 is installed, which is affected by the end of the lever screw of the automatic density control mechanism in the underside (not shown).

The upper end 9 of the slider 3 enters the hole 12 of the lug of the I3 of the block 1. On the spring-loaded slider 3, on the side of the needles (not shown) of the needle cylinder, there are fastened a curtain 14 and a sub-curved 5 wedge. From the opposite side in the middle of the ram

3 groove 16 is completed with the contact plane 17. Opposite the groove 16 in the block

1, a hole 18 is formed in which a housing 20 with a through hole 21 is installed with a screw 19. The axis 22 of this hole is perpendicular to the axis 23 of the spring-loaded slider 3 and parallel to the contact plane 17. In the opening 21 of the housing 20 g position of the slider 3

The tool 24 is made in the form of a roller 25 with a cam 26 fixed on it (Fig. 2 and 3). The roller 25 has a smooth surface and is located in the hole 21. The cam 26 interacts with the contact plane 17 and is shaped according to the Archimedean spiral according to dependence (Fig. 4 )

The housing 20 is made in the form of a sleeve with a tapered shoulder 27 (Fig. 2 and 3), which has a small diameter facing the ring 28 mounted on the end of the roller 25 with a screw 29. The tapered shoulder 27 is a limb: divisions in the form of scratches evenly spaced in the range of variation of the entire angle of rotation of the cam 26 (Figures 1 and 3). For the counting of the divisions on the ring 28, the installation risk 30 is accomplished. This ring is provided with a locking screw 31, for example, a spring-loaded lock, and a knurling (not shown), since it serves as a head for hand turning. The end of the roller 25 is provided with a slot 32 (Fig. 1).

The device works as follows.

On all in the hall systems of the circular machine, all the cuspid wedges 14 are set (for example, using shtangenraysmus) to the same position — to the zero depth of stunking, which corresponds to the extreme upper position of the slider 3, i.e. it stops at block 13 of the block I, while the cam 26 with its smallest radius RMMH contacts the contact plane, 1 7 of the groove 16. The ring 28 is re-secured with a screw 29 so that the risk 30 is fixed against the mark O of the limb of the body 20, while the roller 25 is held by slot 32 from rotation, for example, by

screwdrivers. After that, in order to reach the desired depth of h, the ring 28 is rotated with the roller 25 to the required limb marks equally for all in the hall systems. After the necessary rotation, the device is fixed with a locking screw 31. As a result of rotation of the roller 25 of the means 24 for changing the position of the spring-loaded slider 3 by a certain angle relative to the mark of the limb (which corresponds to the zero depth), the cam 26 also turns at the same angle, displacing the spring-loaded slider 3 to the appropriate depth of propagation due to the fact that the cam 26 is shaped in an Archimedean spiral according to the RR dependence (and in this position interacts with the contact plane 17 m radius R. When installing the cam 26 in the position in which it interacts with the contact plane 17 with its maximum radius kmax, provided the greatest depth kulirovani - range control H which can be set vruchnuyu.Sledovatelno, provided depth adjustment depending on kulirovani

In addition to setting the depth of the manual, perhaps automatic; some increase in the depth of cooling.

 For this purpose, the end face of the screw 10 is driven by a lever transmission mehaniz227735 .Л

The automatic adjustment of the density in the knuckle (not shown), while the spring-loaded slider 3 is shifted downwards, when this action 5 is stopped, the slider 3 under the action of the spring 4 rises up to the stop with the contact plane 17 into the cam 26.

Thus, in the proposed device for adjusting the density in the underdrive on circular knitting machines, the accuracy of the slider movement is ensured, and consequently, the exact setting of the sticking depth is achieved by making the cam along the arch of the honey spiral, as it makes it possible to perform a uniform limb division scale, each division which corresponds to an increase in the cam radius by the same magnitude of the increase in the depth of the population. Improving the accuracy of the setting of the depth of cooling improves the quality of the knitwear produced by obtaining a predetermined loop length that is equal to each in the entrance system. The depth of the stitch is set only by division, and the roller on which the cam is fixed should not be turned one full turn even

3Q when installed on the entire range of regulation N. This simplifies the maintenance of the device, since there is no need to count the number of revolutions of the roller on each in the hall system, and reduces the time required for adjustment to a certain depth of cooling, i.e. increases machine CPV.
