Pulling roll is used in the manufacturing of sheet glass, is used for the glass ribbon that is used to form sheet glass is applied tension force, thus the nominal thickness of feed glass plate.For example in the overflow down draw fusion process, (see No. the 3rd, 338,696, the United States Patent (USP) and the 3682nd of Dockerty, No. 609), pulling roll is placed on the fusion tip of pipe or the downstream of root, and the glass ribbon that is used for regulating formation leaves the speed of fusion pipe, thereby determines the nominal thickness of final sheet glass.
Successful pulling roll can satisfy a large amount of competing standards.At first, pulling roll should be born to the long duration high temperature that the glass of new formation has.Pulling roll perseverant time under this environment is of a specified duration more good more, because can reduce the amount of the final glass that particular machine can make when replacing pulling roll, thereby improves the final cost of glass.
Secondly, pulling roll should produce is enough to the traction action of feed glass thickness power.Can become the glass ribbon middle portion of the final glass of available for fear of destruction, described roller only can be at the glass ribbon edge limited zone contact glass ribbon.Therefore can only produce traction action power in these zones.But being applied to reactive force on glass can not be excessive, because this can cause surface breakdown, can propagate in the available middle portion of glass ribbon.Therefore, roller is realized balance between should be at the reactive force that applies to glass too little and too big.
The 3rd, annular knurl plate (millboard) material that is used for constituting pulling roll should be rigid enough to and bear the technology that long-time manufacturing processed for example causes because of glass cullet and damage.
The 4th, pulling roll should not discharge excessive particle, and these particles may be bonded on glass, forms the surface imperfection that is called as pollutent on the face (onclusion).For being used for the glass that high request is used, the substrate that for example is used for flat-panel monitor, the amount of pollutent must remain on extremely low level on the face, and this is because pollutent all can become a defect area (for example one or more defective pixels) in the finished product usually on each face.Because pulling roll is operated under awfully hot environment, make material to apply enough traction action power to glass ribbon, under awfully hot situation, can not discharge particle simultaneously, this is a very difficult challenge.
Pulling roll is preferably designed to the outer ledge of glass ribbon and contacts, specifically, be positioned at the edge of glass ribbon thickening edge-melting (bead) with the position.The structure of preferred this roller is used the dish of thermotolerance material, annular knurl plate for example, and it is installed on the drive shaft.This example of structure can be referring to No. the 3rd, 334,010, the United States Patent (USP) of Moore, the United States Patent (USP) the 4th of Asaumi etc., 533, No. 581, and the United States Patent (USP) the 5th, 989 of Hart etc., No. 170, these documents all are incorporated by reference into herein in full, are used to describe the example of pulling roll structure.
Existing pulling roll can't satisfy fully that high-temperature long-life life, controlled reactive force apply, the standard of hardness and low these competitions of contaminative.Therefore, this area needs a kind of pulling roll, and it can obtain to be better than these performances of existing pulling roll.
