[0004] In current flat glass processing equipment, molten glass flows out of the furnace flow channel, flows to the lip brick of the calender, and is then drawn into the embossing rollers. Since the width of the furnace flow channel and the width of the calender are not consistent, the flow to The glass liquid on the lip brick is thick in the middle and thin on both sides, or even none on both sides. The forming of flat glass depends entirely on the extrusion of the embossing roller. When embossing, the roller bears a lot of pressure, and the service life is not long. After extensive searching , an ideal technical solution to prolong the service life of patterned rollers has not been found

Embodiment Construction
[0015] In order to make the present invention clearer, the device will be described in detail below in conjunction with the accompanying drawings. The specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.
[0016] Such as figure 1 As shown, the present invention provides a pre-flattening device for flat glass calenders, including calender lip tiles 1, and correspondingly arranged flat rollers 2 and patterns are arranged on the rear side of the calender lip tiles 1. Roller 3, the structures of the lip brick 1 of the calender, the flat roller 2 and the patterned roller 3 and their cooperation relations are all prior art, and will not be described in detail here.
[0017] The calender lip tile 1 is provided with a box body 4, the upper side and the front side of the box body 4 are open structures, and the back and side surfaces of the box body 4 are fixedly connected to the calender lip tile. On t...

The invention relates to a front flattening device for a flat glass calender, comprising a lip tile (1) of the calender, and correspondingly arranged flat rollers (2) and pattern rollers (3) on the rear side of the lip tile of the calender ), a box (4) is provided on the lip brick of the calender, and a gate (5) is connected to the side of the box opposite to the plane roller and the pattern roller, and a support beam (6) is provided on the upper side of the box , the support beam (6) is connected to the gate (5) through the lifting device (7). The advantages of the present invention: the device does not change the mechanism of the existing calender, and the whole device has a simple structure and low cost. And the force of the patterned roller is greatly reduced when squeezing the glass liquid, which reduces the wear of the patterned roller and increases its service life. its versatility.
Description
technical field [0001] The invention relates to the technical field of flat glass production, in particular to a front flattening device for a flat glass rolling machine. Background technique [0002] The flat glass calender is a flat glass forming equipment. It is mainly used for the production of solar glass cover plates at present. It relies on the opposite rotation of the rollers to squeeze the molten glass to make it into flat glass. [0003] In order to reduce the reflection of sunlight, the solar glass cover plate is processed into a structure with a flat surface and a textured surface on the other surface. For this reason, the lower roller of the extrusion pair roller is a flat roller, and the upper roller is a patterned roller. The extrusion pair of rollers undertakes two functions, one is to squeeze the glass liquid, and the other is to suppress the pattern. The extrusion pair of rollers wears quickly. After the flat roller is worn, it can continue to be used after...
