Description

cl

This invention relates to a textile machinery industry and can be used in reelers.

The purpose of the invention is to increase reliability by eliminating premature belt wear.

Figure 1 shows a general view of a device for sucking fibrous material; figure 2 - node I in figure 1, in the section (enlarged); on fig.Z - section aa in figure 2; figure 4 - section bb in fig.Z.

The device for removal of the fibrous material consists of the receiving umbrella I, the removal of the fibrous material from which is carried out by the connecting rod-crank system of the movable duct 2.

The movable air duct 2 is provided with an exhaust nozzle 3, in which a window 4 is made. The exhaust nozzle of the movable air duct ends with a knee 5 telescopically connected to it, placed in the stationary channel 6. The air duct 2 moves along the channel 6 together with the carriage 7 of the baler.

PaNftca 8 is mounted on the knee 5, on the brackets of which the deflecting rollers 9 and seals 10 are placed. The knee has a removable wall 11. On the side of the knee there is an elastic plate 12 that overlaps the section of the channel 6.

Guiding tracks 13 are attached to the frame B, along which a tape 14 is passed through the window 4 of the outlet pipe of the movable air duct, closing the gap of the stationary channel.

There are straps 15 mounted on the tape that prevent it from sagging.

Frame 8 is pressed to the channel 6 by the springs 16, mounted on the leading columns 17, mounted on the exhaust pipe 3 of the movable duct.

The guide columns enter the sleeves 18 mounted on the brackets of the frame 8.

one

The seal 19 creates a tightness of the movable joint of the knee 5 with the exhaust pipe 3 of the movable duct 2.

The device works as follows.

The fan (not shown in the drawing) sucks air from the receiving umbrella 1 of the bale discharger. Fiber in stream

air moves through the movable duct 2 and the stationary channel 6 to the condenser of the downstream machine.

The elastic tape 14 is tightly pressed against the duct of the channel 6.

The movable air duct 2 with the outlet nozzle 3 moves along the stationary channel 6 together with the bale changer carriage 7.

The movement of the air duct 2 through the columns 17 to the sleeves 18 is transmitted to the frame 8 and the knee 5 rigidly connected with it.

In the process of movement, the deflecting rollers 9 lift the belt at the entry point into the stationary channel 6 of the bend 5 on the frame 8 and feed it to the guide tracks 13. Along the guide tracks 13, the tape passes into the window 4, made in the upper

the pipe 3 of the movable duct and enters under the second pair of rollers 9, which are pressed against the duct of the channel 6.

Window 4 made in graduation

the pipe splits the air flow in the movable duct 2 into two streams converging at the knee 5.

Two-way air supply to the knee reduces height

that part of the outlet that is located under the window. The small height of the part of the discharge pipe located under the window allows reducing the height of the belt lifting

bending, which contributes to a reduction in the angle of coverage of the rollers 9 and a reduction in the magnitude of alternating loads arising at the points of attachment of the strip 15 with the tape 14.

The bending radius of the tape as it passes through the guide tracks 3 that are passed through the window 4 of the outlet nozzle will be quite large and the tape 14 will not be stretched in places where the strips are attached to it during the passage of the tracks.

Reducing the height of the ribbon,. small bend radii reduce the stresses in the belt 14 at the points of attachment of the strips to it and significantly increase the reliability of the device.

The telescopic joint of the knee 5c with the outlet pipe of the 3rd half of the air duct allows to compensate

The errors in the manufacture of the duct of the stationary channel 6, and the springs 16 mounted on the columns 17, ensure that the frame 8, the elbow 5 is tight to the top of the duct of the stationary channel 6 and the tightness of this joint.

As the moving duct 2 moves along the stationary channel 6, the edges of the plate 12 are pressed tightly against the walls of its duct, limiting the suction zone.

In order to dismantle the knee 5, if necessary, it is enough to remove the guide tracks 13 from the frame 8, separate the removable wall 1I from the knee 5 and roll out the frame with the knee from the dimensions of the bale opener.
