This invention relates to textile washering and can be used in cotton processing machines.

The aim of the invention is to improve the convenience of service.

Figure 1 shows the drum section; figure 2 - section aa in figure 1; on fig.Z - section BB in figure 1; 4ig.4 - node I in FIG.

The drum consists of a shaft 1 with fixed supporting disks 2 fixed on it, which are separated by alternating mounting 3 and locking 4 gaskets. The discs 2 and the gaskets 3 and 4 are axially clamped by the nuts 5.

The locking gaskets 4 have end annular grooves 7, which are guides for plate retainers 8, made in the form of thin curved plates of spring material. The retainers are installed in the guides of two adjacent retaining pads 4. The retaining pads 3 along the outer contour have cavities 9 within which the retainers 8 move. The recesses 9 provide access to the retainers 8 outside the drum.

Sectors 10 of the saw blades are provided with slotted holes 11, open in the lower part facing the shaft 1, as well as protrusions - guides 6 entering the corresponding cavities 9 on the support disks 2.

The drum is assembled as follows.

Supporting discs 2 and gaskets 3 and 4 are fixedly mounted on the shaft) Retainers 8 are inserted into grooves 7 within hollows 9 of gaskets 3. Next, the drum is tightened with nuts 5. At this, the retainers should move freely without jamming in the guide grooves 7, which is provided by the dimensions of the slots 7 and the clips 8.

To install removable sectors 10, the latches 8 are displaced, occupying a position opposite the open portions of the holes 11. Next, the sector 10 moves in a plane perpendicular to the axis of the drum, and is installed in the slot

formed by the end walls of the gaskets 3 and 4 and the outer face of the supporting discs 2.

When this protrusion 6 falls into the corresponding depression of the disk 2, which centers the sector 10 in the desired position.

When the latch B is moved in the direction of the closed part of the holes 11, the latch 8 is jammed between the outer surface of the guide 7 and the face of the hole 11. At the same time, due to the spring properties of the latch 8, the sector 10 is radially pressed against the supporting disc 2, T.ie. to the drum and secure its fixation.

The removal of sectors 10 is carried out by moving the latches 8. in the direction of the open part of the opening 11.

This design allows for rational use of expensive saw steel, timely replacement, without disassembling and disassembling the saw drum, one or several sectors of the saw disks, and increasing the productivity of machinins due to the timely replacement of worn sections and reducing the time for this replacement.

Claims (1)

Invention Formula A saw drum of a fiber processing machine containing saw blades mounted on a shaft, saw blades made up of sectors, and mounting and fixing pads arranged between the discs, the latter of which are provided with annular grooves for fixing the disc sectors, in order to improve the convenience of servicing the drum the disk sectors are filled with slotted openings on the shaft side, and the installation shims have depressions opposite the slotted holes in the disk sectors, while the latter have plate clamps installed in each hole, the ends of which are located in annular grooves of adjacent fixing pads.
