Description

Technical Field

[0001] The utility model belongs to the field of substrate glass manufacturing, and in particular to a replaceable edge roller structure for the production of large-draw substrate glass. Background Art

[0002] With the continuous development of market demand, the manufacturing technology of liquid crystal substrate glass has gradually matured, and a number of substrate glass production investment companies have emerged at home and abroad. Therefore, the yield rate and production cost of substrate glass manufacturing will become the focus of attention, and the production equipment for large-draw substrate glass will become the direction leading substrate glass manufacturing. However, the larger the draw amount, the faster the production beat, which will bring some problems to production, such as the problem of adjusting the draw thickness and width of the edge roller, the problem of long downtime for replacing the whole edge roller, the problem of long processing cycle and high procurement cost of the whole edge roller. As one of the key equipment for the hot-end production line of large-draw substrate glass, due to the increase in production draw amount, the rotational speed of the edge roller as a key drawing component will increase accordingly, which will increase the contact time between the edge roller body and the glass liquid per unit time, naturally increasing the wear of the edge roller body and causing the replacement frequency of the edge roller body to accelerate. In the process of substrate glass production, the hot-end production is continuous and uninterrupted. During the production process, the running state of the edge roller directly determines the quality of the glass plate being pulled down. After the edge roller is worn, the longer the replacement time, the greater the production loss. Moreover, the processing cycle of the whole edge roller is long and the procurement cost is high. How to quickly replace the edge roller and resume production in the shortest time has become a direct problem restricting substrate glass production. Summary of the Invention

[0003] The purpose of the utility model is to provide a replaceable edge roller structure for the production of large-draw substrate glass, so as to solve the problem of long replacement time of the edge roller in the prior art.

[0006] The replaceable edge roller body is provided with an installation and fitting hole, and the replaceable edge roller body is detachably installed on the edge roller main shaft through the installation and fitting hole. The edge roller main shaft is provided with a screw fixing hole, and the replaceable edge roller body is provided with an edge roller body installation hole. The fastening screw passes through the screw fixing hole and is threadedly connected with the edge roller body installation hole.

[0007] Further, a chamfer is provided at the orifice position of the installation and fitting hole.

[0008] Furthermore, the replaceable edge drawing wheel body is installed concentrically with the main shaft of the edge drawing machine.

[0009] Furthermore, a relaxation pad is provided between the fastening screw and the screw fixing hole.

[0015] Furthermore, the surface of the replaceable edge-pulling wheel body is provided with triangular teeth, and the number of teeth of the triangular teeth is 1701 to 2583 teeth.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The utility model provides a replaceable edge wheel structure for producing substrate glass with a large output amount. By opening a mounting matching hole on the replaceable edge wheel body, the replaceable edge wheel body can be detachably mounted on the main shaft of the edge machine, and fixed on the main shaft of the edge machine with a fastening screw made of a high-temperature resistant material, so that the replaceable edge wheel body can be quickly installed and replaced, which not only reduces the processing cost of the overall edge shaft, but also reduces the difficulty of installing the edge wheel, and shortens the downtime of edge wheel replacement. The utility model tightens the glass plate by two replaceable edge wheels, and realizes the overflow and downward pull of the substrate glass by the relative rotation speed of the two edge wheels and the overall outward movement distance, which is used to control the width of the glass plate in the key process of substrate glass manufacturing and molding, and further adjust the thickness of the glass plate, so as to achieve the purpose of stable downward pull of the overflowing glass liquid. Moreover, only replacing the edge wheel body reduces the production cost and processing difficulty at the same time, and adaptively solves the problem of fast wear of the edge wheel in the production of substrate glass with a large output amount.
