Abstract
The invention discloses a sealing device for a cooling cylinder. The sealing device comprises a movable seal ring and a stationary seal ring sleeving a cooling roller shaft head as well as a short water inlet cylinder arranged at the tail end of the cooling roller shaft head, the short water inlet cylinder is provided with a water inlet in the center of the cooling water inlet end, and four layers of bowl-shaped elastic metallic gaskets laid in pair are embedded inside the short water inlet cylinder; the movable seal ring is fixed o the shaft head through six fastening screws distributed evenly, and O-rings are arranged at the step position of the end of the shaft head and inside the movable seal ring; the stationary seal ring adjoins the stationary seal ring and is arranged at the tail end of the shaft head, an O-ring for contact seal of the short water inlet cylinder is arranged on the side face of the stationary seal ring, and a magnetic seal ring for attached contact with the metal gaskets in the short water inlet cylinder is arranged on the bottom face of the stationary seal ring. The paired elastic metallic gaskets in the short water inlet cylinder are utilized to enable contact end faces of the stationary seal ring and the movable seal ring to be closely attached in a gapless manner so as to be sealed, and the sealing device is simple in structure and good in sealing effect.
Description
Technical field
The present invention relates to a kind of seal arrangement, particularly relate to the seal arrangement for cooling roller.
Background technique
The cooling roll of cooling roller itself does not have cooling capacity, cooling equipment is needed to cool cooling roll aside, general cooling roller needs outfit water chiller, water chiller can carry the chilled water of constant-temperature constant-current to cooling roll, cooling roll possesses runner, can be used for chilled water flow inner through it.Its flow process is: casting films flows through cooling roll, the heat of film can pass to roller, the inside of roller continues to flow chilled water, heat transmits again and gives chilled water, chilled water takes roller out of heat, and dissipate through refrigerating water sets, by continuous circulated refrigerated water, cooling roll completes cooling purposes like this.
In printing packaging machinery, the normal cooling roller using tap water to carry out cooling needs seal arrangement between water intake and the roller spindle nose that is rotating, but existing sealing device structure is more complicated, and sealing effect is not ideal enough.
Summary of the invention
The object of the invention is to overcome the above problem that prior art exists, be provided for the seal arrangement of cooling roller, simple structure and sealing effect is good.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
For the seal arrangement of cooling roller, comprise the rotary packing ring and stationary seal ring that are sheathed on cooling roll spindle nose, also comprise the short cylinder of water inlet being located at cooling roll spindle nose tail end, the short cylinder of described water inlet is positioned at and is provided with water intake into cooling water end (W.E.) center, and inside is embedded with 4 layers of bowl-type flexible metal gasket laid in pairs; Described rotary packing ring is fixed on spindle nose by equally distributed 6 fastening screw trip bolts, and the placed inside of step place, described spindle nose termination and rotary packing ring has O RunddichtringO; Described stationary seal ring is close proximity to rotary packing ring and is located at the tail end of spindle nose, and side is provided with touches with short socket joint of intaking the O RunddichtringO sealed, and bottom end is provided with metallic shim in cylinder short in water and fits the magnetic gasket contacted.
Further, described rotary packing ring is made up of wear-resisting, corrosion resistant Ti metal.
Further, described stationary seal ring is made up of graphite.
The invention has the beneficial effects as follows:
The present invention utilizes and is located at into the paired metallic elastic pad in the short cylinder of water, makes stationary seal ring contact gapless the fitting tightly of end face with rotary packing ring and seal, simple structure and sealing effect is good.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, and form a application's part, schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
