SU95851A1 - Movable Molding Nozzle in Glass Tube Manufacturing - Google Patents

Description

Movable molding nozzles in installations for the production of glass tubes are known.

The glass tubes are molded with a flawless method of their manufacture by means of a refractory molding nozzle embedded in the bottom of the machine chamber. At the same time, in order to obtain high-quality glass pipes, it is extremely important to ensure the constancy of the protruding part of the nozzle by the level of the glass mass mirror. The level of glass melts, due to a number of technological factors, is subject to considerable fluctuations.

In the present invention, in order to automatically adjust the position of the upper edge of the nozzle from. in relation to the glass mass level, it is proposed to maintain a predetermined height of the protruding part of the nozzle when the level of the glass mass in the bath is changed by using a refractory float associated with the nozzle and placed on the glass surface as an impulse for vertical movement of the nozzle.

On fng. Figure 1 shows an installation for the production of glass pipes by means of a lifting and lowering nozzle that automatically moves when the glass mass level changes; in fig. 2-principle electro-knnematic scheme of automatic adjustment of the lifting and opscan molding nozzle.

The molding nozzle 2 fixed in the housing 3 is passed through the bristle chamber dcho / camera. The postPORT is rigidly connected with the nuts 4 moving along the two vertical screws 5 during the rotation of the shaft 6 on which they are mounted. The shaft 6 is rotated through the reducer 7 by a reversible electric motor 8, the start of which is carried out through the systems} of the regulating and automatically operating devices of the refractory float 9 located on the surface of the glass mass of the aircraft chamber.

Automatic adjustment

lifting and lowering the rolling molding nozzle occurs

with. in the way. When the glass melt level is measured in the bath furnace, the float 9 through the acceleration gear 10 turns the rotor of the selsyn 7 / ia sensor to a certain angle. The rotor of the receiving selsyn 12 rotates at the same angle, with the -jTOM brush /.i with dpskom, fixed to the rotor shaft iia a little ce 1 xin 14, touches one of the half-rings, nasa / kenpyh on the drive shaft 6 of the nozzle 2.

As a result, one of the intermediate relays 15 is triggered and the roar of the powerful motor 8 is turned on via an appropriate magnetic actuator 16. The motor drives gear shaft 6 through gearbox 7, from which two screws 5 rotate through gear 17.

In this case, the lifting mechanism

but zhezhepie, according1op1, its new position of the float 9.

When 1tsek 13 will be on the nzol. In the schonnom gap between the G10-lucol, amineremiy selsyn 14, the intermediate intermediate 11-relay 15 is de-energized and the electric motor) stops.

PRAUTION OF THE SHADOWS

Forward molding molding nozzle p. Installation dl production stack; H1P11x pipes, so that, in order to automatically control the position of the upper edge of the seat (hygienically the level of glass mass in the subman u1I1) chamber, its lifting and lowering device is connected with the float, Duplex PA surface glass.
