Description
Technical field
The present invention relates to a kind of sealing device, more particularly to a kind of sealing device for cooling roller.
Background technology
The chill roll of cooling roller does not have cooling capacity in itself, cooling device is needed aside to be cooled down to chill roll, general cooling roller needs to be equipped with a cooling-water machine, and cooling-water machine can convey the chilled water of constant-temperature constant-current to chill roll, chill roll possesses runner, can be for chilled water flow through inside it.Its flow is：Casting films flow through chill roll, and the heat of film can pass to roller, and the inside of roller does not stop chilled water, heat has passed to chilled water again, and heat is taken out of roller by chilled water, and chilled water dispenser group is dissipated, by continuous circulated refrigerated water, chill roll completes cooling purposes like this.
In printing packaging machinery, the cooling roller often cooled down using running water needs sealing device between water inlet and the roller spindle nose being rotating, but existing sealing device structure is more complicated, and sealing effectiveness is not ideal enough.
The content of the invention
It is an object of the invention to overcome the problem above that prior art is present there is provided a kind of sealing device for cooling roller, simple structure and sealing effectiveness is good.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions：
A kind of sealing device for cooling roller, rotary packing ring and stationary seal ring including being sheathed on cooling roller shaft head, also include the short cylinder of water inlet located at cooling roller shaft head end, the short cylinder of water inlet, which is located at into cooling water end (W.E.) center, is provided with water inlet, and inside is embedded with the 4 layers of bowl-type laid in pairs flexible metal gasket；The rotary packing ring is fixed on spindle nose by equally distributed 6 trip bolts, at the step of the spindle nose termination and the placed inside of rotary packing ring has O-ring seal；The stationary seal ring is close proximity to rotary packing ring and located at the end of spindle nose, and sideways provided with the O-ring seal that sealing is contacted with short cylinder of intaking, bottom face is provided with the magnetic gasket for contact of being fitted with metallic gasket in the short cylinder of water.
Further, the rotary packing ring is made up of wear-resisting, corrosion resistant titanium.
Further, the stationary seal ring is made up of graphite.
The beneficial effects of the invention are as follows：
The present invention makes stationary seal ring contact gapless be brought into close contact of end face with rotary packing ring and seal using the paired metallic elastic pad in the short cylinder of intaking, simple structure and sealing effectiveness is good.
Brief description of the drawings
Accompanying drawing described herein is used for providing a further understanding of the present invention, constitutes the part of the application, and schematic description and description of the invention is used to explain the present invention, does not constitute inappropriate limitation of the present invention.In the accompanying drawings：
Fig. 1 is the structural representation of the present invention；
Label declaration in figure：1- rotary packing rings, 11- trip bolts, 12-O type sealing rings, 2- stationary seal rings, 21-O type sealing rings, 22- magnetic gaskets, the short cylinder of 3- water inlets, 31- water inlets, 32- metallic gaskets, 4- spindle noses, 41-O type sealing rings.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the present invention is described in detail.
Shown in reference picture 1, a kind of sealing device for cooling roller, rotary packing ring 1 and stationary seal ring 2 including being sheathed on cooling roller shaft head 4, also include the short cylinder 3 of water inlet located at cooling roller shaft head 4 end, the short cylinder 3 of water inlet, which is located at into cooling water end (W.E.) center, is provided with water inlet 31, and inside is embedded with the 4 layers of bowl-type laid in pairs flexible metal gasket 32；The rotary packing ring 1 is fixed on spindle nose 4 by equally distributed 6 trip bolts 11, at the termination step of spindle nose 4 and the placed inside of rotary packing ring 1 has O-ring seal 41,12；The stationary seal ring 2 is close proximity to rotary packing ring 3 and located at the end of spindle nose 4, sideways provided with the O-ring seal 21 that sealing is contacted with short cylinder 3 of intaking, and bottom face is provided with the magnetic gasket 22 for contact of being fitted with metallic gasket 32 in short cylinder 3 of intaking.
Further, the rotary packing ring 1 is made up of wear-resisting, corrosion resistant titanium.
Further, the stationary seal ring 2 is made up of graphite.
The operation principle of the present embodiment is as follows：
Rotary packing ring 1 is made up of wear-resisting, corrosion resistant titanium in the present invention, it is fixed on by 6 uniform trip bolts 11 on spindle nose 4, at the termination step of spindle nose 4 and the placed inside of rotary packing ring 1 has O-ring seal 41,12, this causes spindle nose 4 to remain rotation simultaneously with rotary packing ring 1；Stationary seal ring 2 is made up of graphite, its side has O-ring seal 21 to contact sealing with short cylinder 3 of intaking, the bottom face sealing ring 22 that is magnetic is contacted with 4 layers of laminating of bowl-type flexible metal gaskets 32 laid in pairs in the embedded short cylinder 3 of water inlet, paired flexible metal gasket 32 causes and obtains thrust between stationary seal ring 2 and the sealing contact surface of rotary packing ring 1, formed gapless be brought into close contact and seal, simple structure and sealing effectiveness is good.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for those skilled in the art, the present invention there can be various modifications and variations.Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection.
