Description

The main author. St. No. 83648 issued to a spinning machine, characterized in that for threading the thread on the spindle and increasing the number of revolutions, each of the flyers provided: with a block that rigidly connects its branches, one of which has an inlet duct opening in the side of the chopper of air.

The proposed spinning machine differs from the car by auth. St. No. 83648 in order to use it for wet spinning in a machine, a conveyor passing through the trough in the form of two endless ribbons is applied to the extractor.

FIG. 1 shows schematically a two-spun spinning machine for wet spinning; in fig. 2-supply and exhaust mechanism; in fig. 3 is a diagram of the torsional winding mechanism in section; in fig. 4 is a plan view of the torsion winding mechanism.

In the upper part of the rack / pinch, there are located in the staggered front of the spinning machine in staggered manner the incomplete fingers 2; each finger 2 with a cartridge 4 mounted on it with a roving 5 stands against

your spindle.

In the rack / slot notch 5, a pumping trough 6 is installed, which is automatically filled by piping with a heated contact through which, for example, fiber fibers are drawn in the case of a machine used for a wet sponge. The presence of a float in the trough 6, made in the form of a hollow metal ball, ensures a constant level of contact. A conveyor for a roving is located in the soaking trough 6; the conveyor consists of two endless belts 7, guided by the leading corrugated rollers 5, fixed on axis 9 and supported; roll; 10; Rollers 8 and 10 draw a rope together

through the trough and lead it to the end rollers // and 12 exhaust apparatus.

The exhaust cylinders 13, which receive movement from the main shaft through a gear system, are grooved and fitted in pr between the fluted fingers and 14, spring-loaded with the help of springs 15, which pull the fingers towards the center of the exhaust cylinders.

The feed rollers 11 and 12 have blades 16 at their upper ends, by means of which the spring-loaded fingers 14 are compulsively pushed out of the radial channels of the starter cylinders 13 prior to interacting with the brook sliver. The rollers // and 12 are controlled via intermediate links from the cam 17 of the neck 18 of the hanging flyer 19.

1 The flyer 19 with the block 20, which rigidly connects its branches 21, is mounted with its neck 18 into the fixed platform 22 of the spindle's upper support and produces twisting slivers and winding the obtained yarn on a detachable spindle, working with the leading spindle speed. This embodiment of the flyer eliminates the swelling of the branches 21 in the rotation process and allows a significant increase in speed.

/ The wet spinning process on a spinning machine is as follows.

The end of the roving 3 is fed to the elevator 23 and then the conveyor belt 7. After passing through the contact mass of the soaking oryurt 6, the royanad is fed to the feed and exhaust cylinders 24, and then to the exhaust cylinders 13, between which the fibers receive a given stretch. When exiting from the cylinders 13, the sliver beats off from them by forcibly pushing the fingers 14 with the help of the blades 16 receiving a reciprocating movement from the neck 18 of the hanging flyer 19; as a result, the sliver is automatically fed to the receiving funnel 25 attached to the neck of the flyer.

The end of the sliver, which has entered the plane of the receiving funnel 25, is then 1gled along the outlet channel by air flow into the inside of the cylinder and wound on the cob onto the rotating receiving ribs of the upper part of the spindle.

The removal of the cob, occurs automatically using known devices.

Subject and reference

1- Prilna car on aut. St. No. 83648, which is distinguished by the fact that, in order to use it for wet spinning, for example, bast fibers, which are passed through a soaking trough, the endless conveyor for the latter is composed of two endless bands guided by leading and supporting rollers, jointly guiding the roving through the trough and leading it to the discharge shaft.

2. Prilna car floor. 1, characterized in that in order to prevent and pull the sliver on the exhaust cylinders, you must be provided with spring-loaded lalzets, forcibly pushed out of the radial channels of the shafts, before interacting with the rollers. sliver coming out of the rollers with the help of vanes, controlled through intermediate links from the cam of the neck of the hanging flyer.
