Abstract
A radiation reactor for curing radiation curable products, coatings, inks, etc. The reactor has a plurality of radiation producing lamps carried in an enclosed chamber for directing radiation onto a coated substrate conveyed through the chamber. Supply and exhaust fans circulate ambient air through the chamber for cooling the chamber interior. A coolant carrying pipe is interposed between the lamps and the substrate conveyed to block at least a portion of the radiation field produced by the lamps for cooling the substrate surface.
Claims25
In a radiation reactor, a radiation source comprising a radiation producing device for establishing a projection field of radiation;
- conveyor means for positioning work to be cured within said field;
- conduit means interposed in said field between and in spaced relation to said radiation source and said conveyor means to block at least a portion of said field;
- said conduit means carrying a cooling fluid for absorbing heat generated by said radiation source;
- and means for adjusting the spacing between said conduit means and said conveyor means.
In a radiation cure reactor, a radiation source comprising a lamp assembly for projecting a field of radiation generally in a first direction;
- conveyor means for positioning work to be cured within said field;
- conduit means disposed in said field in spaced relation to said conveyor means;
- said conduit means being for conducting a cooling fluid through said field for absorbing heat generated by said radiation source;
- and means for adjusting the spacing between said conduit means and said conveyor means.
In a radiation cure reactor having at least one lamp assembly for producing a radiation field of projection and means for positioning work to be cured within said field, wherein the improvement comprises conduit means interposed between and in spaced relation to the lamp assembly and the positioning means to block partially the work from the field, said conduit means conducting a cooling fluid through said field, and means for adjusting the spacing between said conduit means and said positioning means.
A radiation cure reactor comprising a housing;
- a lamp assembly mounted within said housing for producing a radiation field of projection;
- means for positioning work to be cured within said field;
- conduit means disposed within said field in spaced relationship to said lamp assembly and said positioning means to block partially said field;
- means for circulating a cooling fluid through said conduit means;
- means for circulating air through said housing for absorbing heat from said lamp assembly and from the work to be cured;
- and means for adjusting the spacing between said conduit means and said positioning.
In a radiation cure reactor having at least one lamp assembly for producng a radiation field of projection and means for positioning work to be cured within said field, wherein the improvement comprises means interposed between and in spaced relationship to the lamp assembly and the positioning means for blocking a portion of the radiation field from and absorbing heat in proximity to the work to be cured, means for adjustably positioning said blocking means within said field to vary the degree of blockage of said field, and means for adjusting the spacing between said blocking means and said positioning means.
