Technical field
The utility model relates to a kind of seal arrangement that connects, and relates in particular a kind of rotary union assembly.
Background technique
Glue-injection machine is that system is covered applying paste equipment inside the cover ditch portion of production line.Swivel joint is the connected element of injecting glue liquid and glue filling nozzle mechanism, it is again the common connection carrier of injecting glue liquid and gas channel, swivel joint has determined the glue of glue-injection machine and being connected and sealing situation of gas transmission pipeline, therefore, rotary union assembly is the critical component of package packing machine lid production line processed glue-injection machine.
The schematic diagram of current rotary union assembly as shown in Figure 1, comprises housing 2-1, rotation mandrel 1-1 and corresponding sealed member, between housing and corresponding Sealing, forms air chamber.Because rotation mandrel is short, the output terminal of rotation mandrel is positioned at formed air chamber, make to rotate being connected in air chamber of mandrel and glue filling nozzle mechanism glue tube, occur that glue leaks once connect sealing, glue mixes in air chamber, make gas passageway stop up, rotate mandrel rotation and be obstructed, glue-injection machine cisco unity malfunction, causes whole piece lid production line processed to stop production.Meanwhile, due to being connected in air chamber of rotation mandrel and glue filling nozzle mechanism glue tube, it is inconvenient to install.
Model utility content
The purpose of this utility model is for the technological deficiency existing in prior art, and provides a kind of sealing reliability good, rotary union assembly easy for installation.
For realizing the technological scheme that the purpose of this utility model adopts be:
A kind of rotary union assembly, comprise housing, rotation mandrel, described housing and described rotation mandrel are rotatably connected, between described housing and described rotation mandrel, be provided with stuffing box gland, seal washer and graphite grazing structure, between described stuffing box gland and described housing, be provided with O RunddichtringO, on described housing, be provided with oil hole, the output terminal of described rotation mandrel extends to described outside, and by sealing between SEALING FITTING and described housing, described rotation mandrel and described SEALING FITTING are for being slidably matched, between described rotation mandrel and described SEALING FITTING, be provided with circle sealing, described housing, SEALING FITTING and the sealing of rotary core shaft end are realized by sealing cover in described SEALING FITTING outside, on described rotation mandrel between described SEALING FITTING and described stuffing box gland, spring is installed, the air chamber that forms sealing between described SEALING FITTING, seal ring, stuffing box gland, O RunddichtringO, graphite grazing structure and housing, the output terminal of described rotation mandrel is connected with glue tube joint sealing.
Described sealing cover is fixedly connected with described housing by screw.
Compared with prior art, the beneficial effects of the utility model are:
1, the rotation mandrel in rotary union assembly of the present utility model extends to outside, and by sealing between corresponding sealed member and housing, the outside in housing that is connected that makes to rotate mandrel and glue filling nozzle mechanism glue tube, the good seal performance of air chamber, seals more reliable.Meanwhile, glue can not be leaked in air chamber, has ensured the rotation of rotation mandrel.
2, the rotation mandrel in rotary union assembly of the present utility model extends to outside, and by sealing between corresponding sealed member and housing, make to rotate the outside in housing that is connected of mandrel and glue filling nozzle mechanism glue tube, be convenient to rotate being connected of mandrel and glue filling nozzle mechanism glue tube, installation, maintenance is more convenient.
Accompanying drawing explanation
Figure 1 shows that the schematic diagram of rotary union assembly in prior art;
Figure 2 shows that the schematic diagram of the utility model rotary union assembly.
