Description
Technical field
The utility model relates to compacting roller technology field, is more particularly a kind of pressure roller of improvement.
Background technology
The effect of pressure roller be the film of extrusion molding or calendering is overlayed with base material equably together with.At present, existing pressure roller normally connection bearing in its both sides rotating shaft in use, rotated by driven by motor pressure roller, and be false pressure by hydraulic cylinder or cylinder to pressure roller, in use, bearing for supporting pressure roller bears larger moment, is easy to be damaged, and affects it and normally uses.In addition, connected by a roller bearing between pressure roller and pressure roller shaft, rub energetically for a long time and also easily damage roller bearing, cause a large amount of wastings of resources, too increase the production cost of enterprise.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, provides a kind of pressure roller of improvement.
The purpose of this utility model is achieved through the following technical solutions:
A kind of pressure roller of improvement, comprise roller shell and roll shaft, it is characterized in that: in described roller shell, roll shaft is installed, roll shaft is set with two bearings, a spacer ring is installed between two bearings, spacer ring is sleeved on roll shaft, the outer end of two bearings is separately installed with a T-shaped inner washer, T-shaped inner washer is sleeved on roll shaft, the outer end of two inner washers is separately installed with an outer washer, two outer washers are sleeved on roll shaft, and the outer end of roller shell is provided with driving cog, and roll shaft is provided with driving cog near left position.
The pressure roller of described a kind of improvement, is characterized in that: described inner washer is provided with seal groove, seal groove is provided with sealing rubber ring.
The pressure roller of described a kind of improvement, is characterized in that: described bearing and inner washer all scribble butter.
The pressure roller of described a kind of improvement, is characterized in that: the external diameter of described spacer ring, bearing, inner washer and outer washer is equal and equal the internal diameter of roller shell.
The utility model has the advantage of:
Pressure roller of the present utility model is provided with two packing rings on roll shaft, this packing ring has installed sealing rubber ring, and bearing and packing ring are all coated with butter, reduce the moment that bearing bears, decrease the wearing and tearing between bearing and roll shaft and roller shell, use more convenient, and long service life, reduce the production cost of enterprise, be conducive to the productivity effect of enterprise.
