Device for crimping textile fiber material by upsetting

The invention relates to a device for crimping textile fibers, in particular infinite synthetic ones Fibers by upsetting, which consists of two rollers and a stuffer box, which is perpendicular to the Roller axes standing wall pair and formed by a further wall pair running parallel to the roller axes is.

In previously known devices for crimping synthetic materials, the stuffer box is through four walls are formed, two of which are walls with the axes of the rollers pressing the material into the compression chamber are adjustable in parallel and in the longitudinal direction, while two side walls are perpendicular to the axes of the rollers and can be adjusted laterally. In particular, with these devices it is necessary to remove them both walls perpendicular to the axes of the rolls of

adjust the end faces of the rollers exactly where the play between the wall and the end face of the roller at smallest, usually a few hundredths of a millimeter. In addition, the game needs to be on the whole the overlap area of both parts is maintained, what the maintenance of the same course of the roll front surfaces and requires both walls perpendicular to the axes of the rolls.

With these devices there is the disadvantage that the machining must be very precise, since any inaccuracy manifests itself in an increased susceptibility to failure of the device, resulting in a significant amount of work and results in a high cost in production.

These known devices also have the further Hachteil that the axes of the rollers noticeably rub out vertical side walls with the pressure of the indented fibers. Some known solutions use inserts in the side walls of the stuffer box, which, however, are precisely processed and after replacement must be set back to the desired game.

There is also known an apparatus which does the sealing the space between the roller and the wall by expanding the ätauchkammer solves so that a stepped The transition occurs and the pasers between the chamber wall and the roll face are penetrated

flat is partially prevented. This device however, only partially improves the sealing of the chamber and facilitates the elimination of the penetration of lasers between the side wall and the roller face resulting disturbances are not.

In addition to the disadvantages mentioned, there is a common disadvantage of all these devices, which with Deposits are provided in the walls of the stuffer box, in that when replacing an insert at least one Wall must be dismantled, which is very troublesome and interrupts the operation of the device for a long time.

The invention overcomes these disadvantages. The invention is based on the object of providing a possibility for easy Exchange of the inlays of the stuffer box walls and a sealing space between the end faces of the To create rollers and side walls of the stuffer box.

For this purpose, the invention provides that inserts can be set in the side walls of a stuffer box are arranged with the side walls perpendicular to the axes of rollers and on adjustable elements are pivotably mounted and provided with adjustable and locking means.

It is useful if the deposits from one Material of lower wear resistance than the wear resistance of the material of the edging rolls exist.

It is advantageous if the deposits pass the edging rollers are assigned for the purpose of touch.

The ¥ esen of the invention and further details the device according to the invention are based on an embodiment example shown schematically in the drawing explained in more detail. Eb show:

Pig. 1 is an elevation view of the direction of the gate in partial section;

Pig. Fig. 2 is a plan view of the same device in partial section.

The entire device is mounted on a frame 1 * In this, edging rollers 2, 3 are arranged on shafts (not shown) (FIG. 1). The stuffer box is formed by walls 4 * 5 running parallel to the axes of the upsetting rollers 2,3 and by two walls 6,7 standing perpendicular to the axes of the upsetting rollers 2,3 (Pig.2). Both side walls 6,7 are provided with inserts 8,8a, which on sliding supports 9 '9a Lie ψ gene. The displaceably arranged in a recess 10 of the stuffer box side wall 6 insert 8 rests on the support 9, in which an adjusting screw 11 is located. This adjusting screw is provided with a collar 12 and a circular scale 13 which is secured on the screw 11 with the aid of a pin 14.

The side wall 6 is through the mediation of a pin

15 pivotably mounted on an adjustable element,

which in this case forms the fixed part of a side wall 16 which is supported against a wedge 17. In this wedge 17, which is actuated with the aid of an adjusting screw 18, there are wedge slots 19, 19a for the passage provided by fastening screws 20 which connect the side wall 16 to the frame 1 and a Allow shifting of the wedge 17.

In the free end of the side wall 6 there is an adjustable and locking means, which in the exemplary embodiment designed as an adjusting screw 21 with a locking nut 22 and as an expanding screw 23 which is supported with its collar ring against two spherical washers 24 »25. From the through A pin 26 secured washers 24,25 ', the spherical washer 24 is on a Segment plate 27, which 'rni't a frame 1 rotatably mounted hand lever 28 is firmly connected and can be pivoted by this.

In the text so far, only one half of the device is described in detail, because the second half Half of the device is designed in accordance with the first half according to the perpendicular to the axes of the edging rollers 2,3 guided plane is symmetrical, which passes through their center. The walls 4, 5 of the stuffer box are on the frame 1 arranged in a known manner, not shown.

Determining the distance A between the side

909838 / UAO

walls 6.7 and end faces of the edging rollers 2.3 takes place by adjusting the stuffer box side wall 6 with the help of the wedge 17 and the adjusting screw 21, while the respective position of the side wall 6 is secured by the expansion screw 23. The distance Δ becomes much larger and with greater tolerance than the previous ones known devices set. The width of the two upset orphans 2, 3 is also reciprocal executed greater tolerance, because the sealing of the Eaumes between the side walls 6,7 and the Upsetting rollers 2,3 by pressing the deposits 8,8a against the end faces of the upsetting rollers 2,3 with the help the adjusting screw 11 takes place until the end faces of the edging rollers 2,3 are in the deposits Pull the trigger 8.8a. This results in a pressure-free contact between the end faces of the edging rollers 2,3 and the inlays 8,8a, with which the stuffer box is sealed against the ingress of textile fibers.

A certain game is only created through deviation the end face plane of both edging rollers 2,3 from the geometrically precise plane, which is perpendicular to their axes. If an insert 8 is partially worn, it is sufficient to use the adjusting screw 11 again to push towards the end face of the rollers.

For the purpose of exchanging worn inserts 8 is first of all by turning the handwheel of the expansion screw 23 Segment plate 27 partially loosened and the expansion screw by means of the hand lever 28 and the segment plate 27

23 and thus äie side wall 6 is completely released. As a result of their swiveling out is an effortless exchange of the inserts 8, cleaning of the chamber from captured individual fibers is possible. By lifting the side wall 6, neither its setting nor the setting of its insert 8 changes.

The device described is suitable for the trouble-free upsetting of textile fiber material. It is easier as well as being easier to use than known devices and, moreover, they can be sealed better as known compression chambers.
