SU1220601A1 - Spinneret for moulding artificial seamless tubular casing - Google Patents

Description

one

The invention relates to the production of artificial sausage casings and can be used on units for the production of hydrated cellulose and protein casings.

The purpose of the invention is to simplify the die design.

FIG. 1 shows the proposed die in the collection, section; in fig. 2 — node G in FIG. one.

The nozzle consists of a body, the upper part of which is made in the form of a cylinder, inside the body 1 there is a hollow insert 2. The cylinder ends with a flange 3 for connection with the flange A of the insert 2. In the flange 3 there is an annular radial recess 5 in which a sealing element is installed (not sign - .chie). At the upper end of the housing 1 there is a calibrated ring 6, which is equipped with a clamping device consisting of a washer 7 and a cap nut 8. The washer 7 forms with the upper end of the insert 2 a working channel 9 of a spinneret.

To ensure the tightness of the joint between the nut 8 and the die body 1, a rubber ring 10 serves. With a cap nut 11, the body 1 connects

with the insert 2 of the spinneret and the sealing element is pressed into the radial recess 5 to ensure the tightness of the connection.

When assembling the spinneret, the washer 7 is centered with a cylindrical pin 12.

Filler works as follows.

The molding solution, for example, viscose, is fed through the opening 13 in the insert 2 and through the working channel 9 enters the precipitation bath solution, which is fed from the outside of the die and simultaneously into the central cavity of the spinneret through the holes 14 in the insert 2. Owing to the settling bath, the viscose coagulates and is regenerated into cellulose seamless endless tube.

The present invention will simplify the die design due to the fact that the calibrated ring is mounted on the upper end of the die housing, and the tong, forming the working channel together with the outer end of the liner, is centered using a simple device.

Due to this construction, the die requires only turning operations without finishing machining.
