Description

The so-called tool is a belt conveyor that feeds and clamps the raw materials (the stems of the bast plants) in the scutching machines during its processing (weaving and chesting) in them.

In FIG. 1 is a side view of the device; FIG. 2 - its top view; FIG. 3 is a section of a pulley rim with a razognzggy tape on it, and FIG. 4-section of the tape with raw material clamped in it by means of a rope.

The device consists of two identical halves, as the machine processes the raw material in two steps: first one end of the stems on the left side of the drawing, and then the other end on the right. In each half there is a pair of pulleys (fi. 1 and 2) 1 and 9 on the left side, and 10 and 11 on the right with a bevelled rim (Fig. 3), with the driving pulleys 9 and 10 sitting on the same axis; For each pair of pulleys, there is an endless elastic band 2 of a special semi-circular profile with a partition groove 3 (Fig. 3 and 4), which the endless cord 5 passing along rolls 4, 12, 13 and others enters during contact with the belt . This contact is achieved by using the CRYTHROUND Surfaces 7, under which the tape 2 runs on the bottom of its fifth section, and in order to reduce friction between them and the tape, there are movable endless gaskets 6 with dry lubrication. When the tape 2 goes freely over the pulleys 1 and 9, the lobe groove in it is compressed, when the tape passes under the flat cross section 7, the wire 5 enters the groove 3 and is clamped in it (Fig. 4), which is placed under the roller 12 raw material The latter is carried by tape into the machine, and its dangling ends are machined there. Further, these machined ends between the receiving roller 14 of the second half of the tool and the end roller 13 of the first half are transferred with the help of a bent rod 8 to the second half, where they, like in the first, are clamped by the cord 5 in the tape 2 of the second half; the ends, which were clamped in the first / half, are released upon leaving the roller 13, 18 is found from item 2, and the second half is adjusted, like the first, through the other compartment of the machine, pTK ljite Si SiA, already ends.

on

subject of the patent. 1. A device for feeding raw materials characterized by the combined use of: a) two moving from the middle pulleys 9 and 10 in one direction elastic bands 2-2 (Fig. 1) with part-like grooves 3 (Fig. 3) and two cords 5 -5 (Fig. 1), each of which tapes is supported by end 1 Qivi 1 and 11 with oblique rims, and b) two curved surfaces 7-7 to ensure the entry of the cord into the notch, and b) two curved surfaces On the surface are endless moving wheels supported by guide rollers. gaskets bb dry lubrication. 2. With the fixture described in paragraph 1, use a curved rod 8 located under the middle pulley between the tape of the left half of the feeder and the cord of the right half of it, designed to pick up the ends of the stems transferred by the first half of the fixture, and to bring them to the second notch of the tape half.
