Description

for example, with a screw-nut drive (Fig. 1-5).

In the hall carriage with known wedges of the loop-forming system (not shown in Fig.) Moves along the rails 40.

In the case of using a single needle bar, one or the second clamping rulers 25, 26 (Figs. 1-5) are rails for the entry carriage.

The normal working position of the collet clamping mechanism corresponds to the compression position of the loop-forming organ 14 of the petal lips 2 under the action of the longitudinal force P created by the elastic element by the spring 11, which is in a compressed state between the right and left tubular stops 7 and 8. Under the action of the longitudinal force P, the inner tube 1 tends to tuck inside the clamping tube 5 and the clamping tube 5 to exit the housing 21 of the collet chuck by the same force. In this case, the clamping tube 5 by the conical section 6 acts on the petal lips 2, which compress the loop-forming organ 14.

The mechanism in the Koval Zani works as follows.

When moving in the hall carriage (not shown in Fig.) Along the rails 40 (or 25 and 26), the loop-forming system acts with its wedges on the control means 17, for example, to carry out the closing operation.

When moving in the through groove of the upper cover 22 of the control means 17, its last tubular part 16 acts on the end part 9 of the clamping tube 5, which, by the conical section 6, acts on the petal lips 2 in a compressed state, will cause the inner tube 1 to move exit from the housing 21 of the collet clamping mechanism, providing the conclusion. Simultaneously with the inner tube 1, the left tubular stop 8 moves; and with the clamping tube 5, the right tubular stop moves 7. Thus, the compressive force of the elastic element of the spring 11 is maintained, and therefore, the longitudinal force P.

Simultaneously with the inner tube 1, the rotary heel 18 is translationally moving in the guide grooves 19 of the fixed removable sleeve 3.

Depending on the combination of the type of guide grooves 19 in the form of helical, rectilinear and combined grooves, the rotary heels 18 receive corresponding motions. Guide grooves 19 in

in the form of helical grooves through the rotary heels 18, rotational movement is imparted to the inner tube 1 and the loop-forming body 14 clamped inside it. At the same time, 5 in the inner tubular part 16 of the control means 17, the right tubular stop 7 rotates. In general, the clamp collet mechanism rotates inside the stationary housing 21 formed by the upper and

0 bottom covers 22 and 23 and tubular body 24.

The immobility of the housing 21 is provided by the clamping rulers 25 and 26. movably mounted in the grooves above 5 of the indicated upper cover 22 and the tubular body 24. The end parts of the clamping rulers 25 and 26 extend through the grooves of the fixed bracket 39 of the base 35.

With the reverse movement of the manager

0 means 17 for performing the remaining operations of the looping process, the latter acts on the shoulder 15 of the right tubular stop 7, which, through its spikes 12, moves the clamping

5, the tube 5 inside the housing 21. The right tubular stop 7 with the end part 9 acts on the spring 11, which through the left tubular stop 8 through the spikes 13 transmits the movement to the inner tube 1. Inner

0, the tube 1 in the reverse movement by means of the rotary flow 18 moving in the guide grooves 19 of the fixed removable sleeve 3 additionally gives the loop-forming body 14 a rotational movement 5.

The extension in the plane of the base 35 of the loop-forming organs 14 to increase the needle pitch is carried out by means of a sliding mechanism in the form

0 for example, rocker-link mechanism.

When exposed to end fingers

30 links 28 and 29 last simultaneously

rotating around center C, move

fingers 30 in grooves 31 of the lower covers 23

5 of the housing 21 of each collet clamping mechanism. In this case, the fingers 30. moving towards each other (Fig. 5), cause the bodies 21 to move away from each other, maintaining a parallel position between them.

0 The C centers of rotation of the links 28 and 29 are shifted away from each other. Accordingly, the casket 32, which is the center of rotation of the links 28 and 29, moves in the grooves 34 by the prismatic support 33, the breakaway tooth 36. In the middle between the housings of the collet chucks.

During the reverse shift of the loop-forming organs 14, the end fingers 30 of the lower covers 23 on each end face of the mechanism are acted upon by the drive to reduce the needle pitch.

The movement of the extension or approach of the links 28, 29 of the linkage mechanism is carried out, for example, by means of a screw-nut transmission. The chain 37 passing through the opening of the fixed bracket 39 of the base 35 imparts a corresponding movement, which is transmitted to the movable bracket 38, which is rigidly connected to the extreme bottom cover 23.

To change the loop-forming organ 14, it is necessary to simultaneously press on the guide heel 17 and button 20, compress the elastic element - spring 11. At the same time, the petal lips 2 of the inner tube 1 will come out of the clamp tube 5. In this case,

5

For the inner tube 1 to change, it is necessary to change the loop-forming organ 14. for example, replace the hook needle with a tongue. After that, unclench the spring 11, which will lead to the reverse compression of the loop-forming organ 14 with the petal jaws 2.

The offered Koval machine allows you to produce knitwear with loops of various shapes - straight, twisted, etc., use different loop-forming organs, process yarn and threads in wide tolerances in linear density by changing the needle pitch.
