Description

The present invention relates to devices for automatically feeding fiber-containing material into scutching machines and the like, provided with a periodically rotating grill, tossing material.

The purpose of the proposed device is to accept fiber-containing material from the mill and automatically feed it to the conveyor belt and the like machine without much help from the worker. The device is necessary not only to release working hands, but also to create a more even supply of the machine and to be able to change the number of feeds per minute upwards, regardless of the individual abilities of the worker servicing the machine.

In the proposed device, through the slits of stepped plates that form the receiving table, the fingers of the lattice flaps pass, which sit on a common axis and interlock when the shoe interacts with the fixed track, which is installed on the part of the rotation path of the flaps.

In the schematic drawing of FIG. 1 is a longitudinal sectional view of a device for automatically feeding fiber-containing material into scutching machines and the like; FIG. 2 - its top view; FIG. 3-section along JV1N of FIG. 2; FIG. 4-section on KR in FIG. one.

The drawing shows one grid. In some cases, two lattices are more advantageous, therefore the second lattice is shown by a conditional dotted line. Raw material is fed from mill to the receiving table formed in steps.

I arranged by plates 2 with slots for passage of a grating made of two finger flaps /, 3. The table is made with ledges to avoid raw material falling into the slots. Finger

i sash / rigidly fixed on axis 4,

 driven by the main shaft of Cmlki using the Maltese cross (L-location of the drive). Maltese cross or other structures create intermittent lattice movements.

Until the handful of raw material is completely out of the discharge rolls D m lki, the grille stands still. the next moment, it turns 360 ° (with one leaf) or 180 ° (with two shutters). With one flap, i.e., when rotated 360 °, a handful is hung on the belt of a scraper conveyor and the like, as shown in FIG. 4. With two flaps, i.e., when rotated by 180 °, a handful is placed on the conveyor belt and on additional rods located on either side of the conveyor belt of the machine. The purpose of these bars is to replace the table (not shown in the drawing).

Since during the rapid movement of the lattice, a handful of raw materials can not only be confused, but also fall off the lattice, it must be held. For this purpose, the fingers of the flap 3 serve, with their lugs loosely mounted on the shaft 4. The fingers of the flaps 3 are rigidly connected to each other by a bar 5. Pin 4 is fastened in the shaft 4, connected by a spring 7 to the flap 3. The flaps 3 are pressed by the action of the spring 7 to the ledge in, creating a throat, necessary for the free entry of a handful on the table. At the other end of the finger of the flap 3 there is a shoe 8, which is pushed by the spring 9 from the axis 4.

As it moves in a clockwise direction, the grating picks up a handful of the raw material that has come out of the mill. The axis 4, lead, and the grille, will mix the flap 3, while the pharynx is maintained only until the moment

Shoe 8 with a fixed track W. At the next moment, the strength of the friction between the shoe 8 and the JO track overcomes the resistance of the spring 7, and a handful will be sandwiched between the flaps 7 and 5. When the shoe 8 comes off the track W, under the action of the spring 7 the pharynx is formed again and a handful is freed. This will happen at the time of laying a handful on the conveyor of the hauling machine. By mixing or changing the length of the track W, it is possible to choose the most advantageous condition for releasing a handful. By appropriately adjusting the standing time and moving the axis 4, one can obtain the desired arrangement of handfuls on the conveyor of the machine, for example, at intervals, end-to-end, overlap.

The subject matter of the invention.

A device for automatically feeding fiber-containing material into scutching machines and the like using periodically rotating lattices throwing material, characterized in that the grille is made of two fingertip flaps 3, which sit on a common axis and are interlocked during the interaction of the shoe 8 with a fixed track on the part of the path of rotation of the valves, the fingers of which pass through the slots of stepped plates 2 forming the receiving table.
