And the thickness of the formed ultrathin flexible glass can be adjusted in real time through the matching of the first conveying roller set 6 and the second conveying roller set 9. The single mother glass plate can be heated and spliced through the splicing melting furnace 7, and the continuous production of the ultrathin flexible glass can be realized.
Alternatively, in one embodiment of the present disclosure, the two first conveying roller sets 6, the secondary forming furnace 8, and the second conveying roller set 9 are disposed in the vertical direction, so that the mother glass sheet is stretched in the vertical direction. Of course, in other embodiments, the two first conveying roller sets 6, the secondary forming furnace 8 and the second conveying roller set 9 may also be arranged along the horizontal direction, so that the mother glass sheet is stretched along the horizontal direction, which may be specifically arranged according to actual needs.
Optionally, in an embodiment of the present disclosure, a slide rail 11 disposed along the conveying direction is further disposed between the two first conveying roller sets 6, and the splicing melting furnace 7 is slidably connected to the slide rail 11.
In the present embodiment, the splicing melting furnace 7 is slidable between the two first conveying roller sets 6 by the slide rail 11. Specifically, in this embodiment, the bottom end of the splicing melting furnace 7 is provided with wheels, the wheels are slidably disposed on the slide rails 11, and the wheels are driven by the servo motor to rotate, so that the servo motor drives the splicing melting furnace 7 to move on the slide rails 11. In the production process, the servo motor drives the splicing melting furnace 7 to move at the same speed as the conveying speed of the first conveying roller set 6, so that the splicing melting furnace 7 can keep the fusion splicing of the mother glass plate. Specifically, in the present embodiment, the splicing melting furnace 7 adopts an electric heating wire, a silicon carbide rod 204 or laser heating, and can rapidly make the mother glass plate reach a molten state, thereby realizing the melting and splicing of the two mother glass plates. The splicing melting furnace 7 is prior art and its structure will not be described in too much detail here. Specifically, in the present embodiment, the slide rail 11 is provided in the vertical direction so that the splice melting furnace 7 can be moved up and down in the vertical direction.
Optionally, in an embodiment of the present disclosure, each of the first conveying roller set 6 and the second conveying roller set 9 includes a first roller 101, a second roller 102, and an opening and closing device, the first roller 101 is disposed parallel to the second roller 102, the first roller 101 and the second roller 102 can hold a mother glass plate, the opening and closing device is in transmission connection with the second roller 102, and the opening and closing device is configured to drive the second roller 102 to be close to or far from the first roller 101.
In the present embodiment, the first roller 101 and the second roller 102 are disposed to face each other, and the first roller 101 and the second roller 102 rotate synchronously and face each other, so that the mother glass plate can be clamped. It should be noted that the first roller 101 is a fixed roller, the second roller 102 is a movable roller, and the second roller 102 can move under the driving of the opening and closing device, so as to adjust the clamping force. The mother glass sheet is positioned between a first roller 101 and a second roller 102. The first rollers 101 and the second rollers 102 of the two first conveying roller sets 6 rotate synchronously, so that two adjacent glass plates are conveyed at the same speed in the two first conveying roller sets 6, and the two first conveying roller sets 6 can perform stable clamping and conveying functions on the glass plates during fusion splicing.
In the embodiment, the opening and closing device can drive the second roller 102 to move, can adjust the clamping force on the plain glass plate, can completely keep the second roller 102 away from the first roller 101, and can take out the plain glass plate during shutdown maintenance. When the plain glass plates are spliced in a melting mode, two adjacent plain glass plates can be aligned, the splicing effect is guaranteed, and meanwhile the stable clamping and conveying effects can be achieved. When the mother glass plate is stretched and thinned, the opening and closing device can drive the second roller 102 to be close to the first roller 101, and the mother glass plate can still be clamped when being thinned.
Optionally, in an embodiment of the present disclosure, the opening and closing device includes a transmission arm 103, a lever 104, a weight 105, a sliding rod 106, and a limiting seat 110, the transmission arm 103 is connected to one end of the lever 104, one end of the transmission arm 103, which is away from the lever 104, is connected to the second roller 102, the weight 105 is used to connect to one end of the lever 104, which is away from the transmission arm 103, one end of the sliding rod 106 is hinged to the middle of the lever 104, the other end of the sliding rod 106 slides through the limiting seat 110, and an end of the sliding rod 106, which is away from one end of the lever 104, is provided with a protrusion for abutting against the limiting seat 110.
In the embodiment, the transmission arm 103 is located at one side of the second roller 102, so that one end of the transmission arm 103 away from the lever 104 is connected to one end of the second roller 102, and the transmission arm 103 drives the second roller 102 to move to be close to or away from the first roller 101. Specifically, the sliding rod 106 is arranged along the vertical direction, and since the middle part of the lever 104 is hinged to the upper end of the sliding rod 106, the lever 104 can rotate around the upper end of the sliding rod 106, when the weight 105 is connected to one end of the lever 104 far away from the transmission arm 103, one end of the lever 104 far away from the transmission arm 103 moves downwards, and one end of the lever 104 close to the transmission arm 103 moves upwards to drive the second roller 102 to be close to the first roller 101. When the weight 105 is removed from the end of the lever 104 away from the transmission arm 103, the end of the lever 104 away from the transmission arm 103 moves upward, and the end of the lever 104 close to the transmission arm 103 moves downward to drive the second roller 102 away from the first roller 101. Therefore, the clamping force between the second roller 102 and the first roller 101 can be adjusted by adding weights 105 to the end of the lever 104 away from the transmission arm 103, so that the operation is very convenient, and the clamping force can be adjusted in time.
Specifically, in this embodiment, the weight 105 is in a circular ring structure, and the weight 105 can be directly sleeved on the end of the lever 104 away from the transmission arm 103, so that the operation is more convenient.
