SCREEN PANEL FRAME WITH PLATE

摘要

A screen panel has a pre-tensioned screen with a polished metal plate mounted to the top of the frame to eliminate all the exposed surface areas of epoxy which secures the screen to the screen panel frame. The metal plate also provides an edge against which a silicone bead may be seated to provide a much cleaner and finished looking panel which is anticipated to meet the standards set forth by the USDA. Additionally, the spatial positioning of the plate atop the screen material and screen frame allows for a clean and smooth transition across the components and one which may accept a finished bead of silicon or other material for reducing and/or eliminating sites for mold growth or other containments thereby enhancing the ability to clean and sterilize the screen panel for the processing of various materials.

主权项

1. A screen panel assembly for use in a vibratory screening machine, the screen panel assembly comprising:
a frame; a perforate screen material extending across the frame to provide a screening surface; an epoxy securing perimeter portions of the perforate screen material to the frame; and a plate positioned atop the frame and sandwiching the epoxy and perimeter portions of the perforate screen material therebetween, the plate having a central opening to thereby expose the screening surface within the frame to allow for passage of material on the screening surface through the screen panel assembly, the plate concealing the perimeter portions of the perforate screen material, wherein the epoxy permanently secures the perimeter portions of the perforate screen material to both the frame and the plate.
