[0026] The specific embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. These embodiments are only used to illustrate the present invention, but not to limit the present invention.

[0027] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "top", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0030] like Figure 1 As shown, the glass melting furnace 1 includes a feeding pool and a melting part. The glass liquid outflow end of the melting part is connected to two branches, namely, a first branch 11 and a second branch 12. The first branch 11 and the second branch 12 are parallel to each other, and the outlet of each branch is connected to a glass production branch line. Each glass production branch line includes a calender 2, a movable roller table 3, and an annealing furnace 4, which are arranged in sequence from near to far from the branch outlet. Specifically, the two branches and the two glass production branches are symmetrically arranged about the center line L of the glass melting furnace 1, and the extension directions of the two branches and the two glass production branches are parallel to the extension direction of the center line L of the glass melting furnace 1.

[0031] The production process of the glass plate is as follows: the raw materials put into the feeding pool are melted in the melting part to form glass liquid, and the glass liquid flows into the first branch 11 and the second branch 12 in equal amounts through the glass liquid outflow end of the melting part, and then enters the glass production branch line. The calender 2 includes a plurality of groups of rollers arranged opposite to each other up and down, and the rollers are used to calender the glass liquid to obtain a glass plate strip. After the glass plate strip is cooled by the movable roller table 3, it enters the annealing furnace 4 for annealing operation to obtain a crystallized plate, and then the crystallized plate is cut on the conveying roller to obtain a glass plate.

[0032] Each glass production branch line includes two calenders 2, one of which is a working machine, which is set at the calendering and forming station at the branch exit to calender the glass liquid; the other is a spare machine, which is stored on a parking track 6 waiting for maintenance and replacement. Both glass production branches are equipped with one for use and one for standby, and are equipped with a total of 4 calenders.

[0033] In order to facilitate the replacement of the rolling mill 2 in the glass production branch line and provide sufficient stop positions, the present invention provides a rolling mill replacement device, which includes a maintenance turntable 5 rotatably arranged between two glass production branch lines, a first track 7 arranged between the maintenance turntable 5 and each glass production branch line, and four stop tracks 6 distributed in an X shape with the maintenance turntable 5 as the center. A second track 51 is arranged on the top of the maintenance turntable 5, and the second track 51 can be connected with the first track 7 or the stop track 6 when the maintenance turntable 5 rotates to a preset angle, and the rolling mill 2 in the glass production branch line can move along the first track 7, the second track 51 and the stop track 6.

[0034] When replacing the calendering machine 2, first rotate the maintenance turntable 5 to align and connect the second track 51 with the first track 7, then push the working machine along the first track 7 into the second track 51, and move the working machine to the top of the maintenance turntable 5; then rotate the maintenance turntable 5 to align and connect the second track 51 with any idle shutdown track 6, and move the working machine to the shutdown track 6; then rotate the maintenance turntable 5 to align and connect the second track 51 with the shutdown track 6 where the standby machine is located, and move the standby machine to the top of the maintenance turntable 5; finally, rotate the maintenance turntable 5 to align and connect the second track 51 with the first track 7, push the standby machine along the second track 51 into the first track 7, and allow the standby machine to enter the calendering molding station of the glass production branch line.

[0035] In a specific embodiment of the present invention, a maintenance groove is provided on the ground between two glass production branches, the depth of the maintenance groove is 475 mm, and a rotating shaft is provided at the bottom of the circular maintenance turntable 5, and the maintenance turntable 5 is rotatably arranged in the maintenance groove through the rotating shaft. The height of the second track 51 is the same as that of the first track 7 / stop track 6, so as to facilitate accurate docking. Furthermore, the two first tracks 7 are located on the same straight line, which is perpendicular to the center line L of the glass melting furnace 1, and the rotating shaft of the maintenance turntable 5 is arranged at the intersection of the two straight lines.

[0036] Furthermore, the four stop rails 6 are symmetrically arranged about the center line of the glass melting furnace 1. Based on the spacing between the first branch 11 and the second branch 12 being 15000 mm, the angle between two adjacent stop rails 6 is 30°. This arrangement can not only realize the machine change operation of a total of four calenders in two adjacent glass production branches, but also reasonably and effectively utilize the limited operating space.

[0037] Furthermore, the first track 7, the second track 51 and the stop track 6 each include two parallel rails. A plurality of wheels are provided at the bottom of the calender 2, and the wheels are in rolling cooperation with the first track 7, the second track 51 and the stop track 6.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
