Method for producing float glass with front rotation point projection and meshing point coincided

Abstract

The invention discloses a method for producing float glass with front rotation point projection and a meshing point coincided. Glass on the liquid surface of a tin tank is dragged to move forwards by means of an edge pulling wheel of an edge puller. The method includes the following steps that firstly, the edge pulling wheel of the edge puller is meshed with the glass to form the meshing point; secondly, the horizontal swing angle of the edge puller is adjusted to change the traction direction of the glass, and the position of the meshing point is not changed in the swing process of the edge puller. When the horizontal swing angle of the edge puller is adjusted, the meshing point where the edge pulling wheel presses the glass is not changed, the edge pulling wheel only rotates at an angle in the original position, and the situation that the edge pulling wheel pressing the glass greatly moves and the glass is driven to swing inevitably when the horizontal swing angle of a traditional edge pulling machine is adjusted is avoided. Glass forming quality is improved, and operation accidents are avoided.

Description

technical field [0001] The invention belongs to the field of float glass equipment, and in particular relates to a float glass production method in which the forward rotation point projection and the joint point overlap. Background technique [0002] Float glass edging machine is one of the key equipment for float glass production, and it is the executor who assists glass forming to set specifications. During production, the edge pulling machine presses the edge pulley or head on the edge of the glass ribbon in the tin tank, controls the thickness and width of the glass ribbon, and cooperates with the annealing kiln to pull out qualified glass. There are many published patents about the float glass edge pulling machine, involving structural transmission, cooling, heat preservation and other aspects. In actual engineering use, because the forward rotation point of the beam is on the outer wall of the tin bath, and the edge wheel on the machine rod is inside the tin bath, the...

AI Technical Summary

Problems solved by technology

In actual engineering use, because the forward rotation point of the beam is on the outer wall of the tin bath, and the edge wheel on the machine rod is inside the tin bath, the point pressed against the edge of the glass is called the occlusal point. Adjust the edge lever in normal production When swinging the angle, the position of the edge wheel must be rotated by an arc to a new occlusal point, especially if it is pressed against the glass and continuously moves the edge wheel, it will drag the glass ribbon to swing or cause other adverse effects, such as making the glass thickness difference, Glass bars, stripes, etc.
