Description
Technical field
The utility model relates to a kind of EVA glued membrane moulding flower roller, particularly a kind of EVA glued membrane moulding flower roller cooling structure.
Background technology
The making of glued membrane is to extrude, be membranaceous vertical curtain coating to moulding flower roller and the moulding rubber roll through screen pack, from the molding die extruding through screw extruder with the EVA particle, is rolled into wounded in the battle line, the uniform glued membrane of thickness.For the EVA glued membrane is relatively easy to peel off on moulding flower roller, moulding flower roller must cool off, and the uniformity of flower roller cooling directly influences the uniformity after glued membrane is peeled off, and the two ends of technological requirement flower roller can not be greater than 1 ℃ with the middle temperature difference.Colored roller of the prior art, its type of cooling are inflows from the flower roller, and flow out the other end; Whole roller body has a tangible thermograde on the width aspect, the temperature that colored roller one end promptly occurred is high, and the temperature of its other end is low; Cause the roller body two ends temperature difference big; Make glued membrane discontinuity when peeling off, cause the glued membrane shrinkage factor big and inhomogeneous, have a strong impact on product quality.
Summary of the invention
The purpose of the utility model is exactly the weak point in the background technology, and a kind of EVA glued membrane moulding flower roller cooling structure is provided.
For achieving the above object, the utility model adopts following technical scheme: EVA glued membrane moulding flower roller cooling structure comprises colored roller; Be separated into left chamber and right chamber through dividing plate in this flower roller; Be equipped with cylindrical shell respectively in chamber, a left side and the right chamber, flower roller two ends are connected with capping respectively, and this capping center is provided with delivery port; Both sides are connected with internal partition respectively in the cylindrical shell; Through the internal partition in the cylindrical shell and capping and internal partition and dividing plate the inner chamber of cylindrical shell is divided into water chamber, separate cavities and intake antrum, inlet channel passes the delivery port of capping successively, the center of two groups of internal partitions in the cylindrical shell is communicated with intake antrum, is provided with out water space between said delivery port and the inlet channel.
For a kind of optimization of the utility model, said cylinder body outer wall is provided with spiral channel, and the cylinder lumen wall of intake antrum is provided with the water injection hole that is communicated with spiral channel, and the cylinder lumen wall of water chamber is provided with the apopore that is communicated with spiral channel.
For a kind of optimization of this utility model, the capping at flower roller two ends is connected with water inlet pipe, outlet pipe through swivel joint respectively, and inlet channel is communicated with water inlet pipe, and outlet pipe is communicated with water chamber through going out water space.
The utility model is compared with background technology, has compact conformation, reasonable, and the temperature of whole colored roller is even; Improved not roll banding of glued membrane, produced defective when avoiding glued membrane to peel off, stopped useless film and produce; Improve the molding effect and the shrinkage factor of glued membrane, increased product percent of pass.
