On-line roller changing device for float glass transitional roller table and roller changing method

Abstract

The invention provides an on-line roller changing device for a float glass transitional roller table and a roller changing method. The device comprises a winch, a pull cart, a connecting rack and a roller discharging cart. According to the on-line roller changing device for the float glass transitional roller table and the roller changing method, tin rubbing devices, supports and rollers of the transitional roller table are connected into a whole through U-shaped assemblies. According to the on-line roller changing device, by adjusting the pre-changing roller positions, the tin rubbing devices, the supports and the rollers are integrally pulled out, hence, on-line roller changing is achieved, operation is easy and convenient, and roller changing time is saved; a roughing slag box is arranged to be in an open type, and changing of the rollers is facilitated. The on-line roller changing device for the float glass transitional roller table and the roller changing method are suitable for the float glass production process, the yield of glass products can be increased, the product quality of the glass products can be improved, and implementation and popularization are easy.

Description

technical field [0001] The invention belongs to the technical field of float glass manufacturing, and relates to a roll changing technology for a roll in a transition roll table, in particular to an online roll changing device and a roll changing method for a float glass transition roll table. Background technique [0002] Float glass transition roller table is the key equipment between the tin bath equipment and the annealing furnace, which belongs to the continuation of the end of the tin bath equipment, and its main function is to lead the glass ribbon at about 600°C from the tin bath to the annealing kiln. In the current technology, the rollers of the transition roller table usually operate at a high temperature above 600°C, and most of the rollers are made of alloy rollers. This material is easy to be compatible with tin compounds such as SnS and SnO from the tin bath at high temperatures, corroding the surface of the rollers Or there will be hard-to-remove build-up on ...

Problems solved by technology

In the current technology, the rollers of the transition roller table usually operate at a high temperature above 600°C, and most of the rollers are made of alloy rollers. This material is easy to be compatible with tin compounds such as SnS and SnO from the tin bath at high temperatures, corroding the surface of the rollers Or there will be hard-to-remove build-ups on the surface, causing serious damage to the rollers, and due to the inherent limitation of the box-type overall structure, it is difficult to replace the transition rollers

[0003] The usual methods of changing rollers include smashing the glass head, narrowing the plate, etc. However, these traditional replacement methods are time-consuming and costly, and the replacement of the rollers needs to stop production, which seriously affects the production
