For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0041] Please refer to Figure 1 and Figure 2 The embodiment of the present invention provides a glass production line (not shown) for producing glass-ceramics. It can realize online roll change of the first rolling roller pair 130, and there is no need to stop the machine during the roll change, thereby ensuring the output.

[0042] It should be noted that the glass production line includes a glass melt feeding device (not shown), a rolling and forming device 100 and an annealing furnace (not shown). The glass melt feeding device, the rolling and forming device 100 and the annealing furnace are arranged in sequence along the flow direction of the glass melt. The glass melt feeding device is used to feed the rolling and forming device 100 so that the glass melt flows into the rolling and forming device 100; the rolling and forming device 100 is used to roll and form the glass melt to obtain a glass ribbon; the annealing furnace is used to anneal the glass ribbon to reduce the hardness of the glass ribbon, eliminate residual stress, stabilize the size, reduce deformation and crack tendency, and finally obtain microcrystalline glass.

[0043] The calendering equipment 100 includes a frame 110, a first calendering pair of rollers 130, a second calendering pair of rollers 140, and a shifting device 150. The shifting device 150 is installed on the frame 110 and is connected to the first calendering pair of rollers 130 and the second calendering pair of rollers 140 at the same time. The shifting device 150 is used to drive the first calendering pair of rollers 130 and the second calendering pair of rollers 140 to move, so as to realize the online roll change of the first calendering pair of rollers 130. The first calendering pair of rollers 130 and the second calendering pair of rollers 140 are arranged in parallel, and the first calendering pair of rollers 130 and the second calendering pair of rollers 140 are both used to calender the glass melt. The glass melt feeding device is connected to the feeding pipe 120, and the glass melt feeding device is used to output the glass melt to the feeding pipe 120. The outlet 121 of the feeding pipe 120 is arranged above the first pair of rollers gap 131. The first pair of rollers gap 131 is arranged between the first pair of rollers 130. The first pair of rollers 130 is used to roll the glass melt output from the outlet 121 into a glass ribbon, and output the glass ribbon from the first pair of rollers gap 131.

[0044] Furthermore, the shifting device 150 is used to drive the second rolling roller pair 140 to approach each other and form the second roller gap 141. The shifting device 150 is also used to drive the first rolling roller pair 130 to move away from each other, so that the second rolling roller pair 140 rolls the glass melt and outputs the glass ribbon from the second roller gap 141. In this way, in the process of rolling the glass melt by using the second rolling roller pair 140 to replace the first rolling roller pair 130, the first rolling roller pair 130 can be replaced, thereby realizing the online roll replacement of the first rolling roller pair 130, and there is no need to stop the machine during the roll replacement, thereby ensuring the output.

[0045] The inventor has found that in the prior art, after the traditional calendering roller is replaced, the new calendering roller needs to be preheated, and the preheating time is long, resulting in a long production process recovery time, which will cause a large loss of production. In this regard, in this embodiment, the first calendering roller pair 130 is arranged above the second calendering roller pair 140, and the shifting device 150 is also used to drive the first calendering roller pair 130 and the second calendering roller pair 140 to rise, so that the feed pipe 120 is located between the first calendering roller pair 130, and the heat radiation of the glass melt in the feed pipe 120 is used to preheat the first calendering roller pair 130. In this way, the calendering molding equipment 100 can preheat the new first calendering roller pair 130 during the roller replacement, effectively shortening the production process recovery time and avoiding production losses.

[0046] Specifically, the shifting device 150 is used to drive the second rolling roller pair 140 to approach each other and form the second roller gap 141, so that the glass ribbon is output from the second roller gap 141; the shifting device 150 is also used to drive the first rolling roller pair 130 to move away from each other, so that the second rolling roller pair 140 rolls and forms the glass melt; the shifting device 150 is also used to drive the first rolling roller pair 130 and the second rolling roller pair 140 to rise synchronously, so that the feed pipe 120 is located between the first rolling roller pair 130, so as to facilitate the replacement of the first rolling roller pair 130 and preheat the new first rolling roller pair 130, and improve the rolling and forming effect of the second rolling roller pair 140. In this way, the online roll replacement of the first rolling roller pair 130 is realized conveniently and quickly, and there is no need to stop the machine during the roll replacement to ensure the output. In addition, the new first rolling roller pair 130 can be preheated during the roll replacement, which effectively shortens the production process recovery time and avoids output loss.

[0047] When the calendering equipment 100 operates normally, the spacing between the second calendering rollers 140 is relatively large, and the glass ribbon output from the gap 131 of the first pair of rollers passes downward through the gap between the second calendering rollers 140 and continues to move downward. During this process, the second calendering rollers 140 will not contact the glass ribbon, but will only be radiated with heat from the glass ribbon, thereby maintaining the preset process temperature so that the glass melt can be directly calendered when the rollers are changed online later.

[0048] When the calendering forming equipment 100 changes the rollers online, the shifting device 150 is first used to drive the second calendering roller pair 140 to move closer to each other, so as to reduce the spacing between the second calendering roller pair 140 and form a second roller pair gap 141, wherein the second roller pair gap 141 is equal to the first roller pair gap 131. At this time, the glass ribbon output from the first roller pair gap 131 passes downward through the second roller pair gap 141, and the second calendering roller pair 140 contacts the glass ribbon; then the shifting device 150 is used to drive the first calendering roller pair 130 to move closer to each other. The first rolling roller pair 130 is moved away from the first rolling roller pair 130 to increase the spacing between the first rolling roller pair 130, so that the glass melt output from the outlet 121 of the feed pipe 120 flows directly to the gap 141 of the second rolling roller pair without contacting the first rolling roller pair 130. At this time, the second rolling roller pair 140 rolls the glass melt output from the outlet 121 into a glass ribbon, and outputs the glass ribbon from the gap 141 of the second rolling roller pair. Then, the shifting device 150 is used to drive the first rolling roller pair 130 and the second rolling roller pair 140 to rise synchronously, so that the feed pipe 120 can be moved away from the first rolling roller pair 130 to increase the spacing between the first rolling roller pair 130 and the second rolling roller pair 140. 0 is located between the first calendering roller pair 130, and the second calendering roller pair 140 is moved up to the position of the original first calendering roller pair 130. At this time, there is no shielding above the first calendering roller pair 130, which is convenient for replacing the first calendering roller pair 130, and the second calendering roller pair 140 has a better calendering effect on the glass melt, ensuring product quality; then the first calendering roller pair 130 is replaced by a hoisting device. After the roller replacement is completed, the new first calendering roller pair 130 remains at the positions on both sides of the feeding pipe 120 unchanged, and the feeding pipe is used to replace the first calendering roller pair 130. 120°C, the new first calendering roller pair 130 is preheated; after the preheating is completed, the first calendering roller pair 130 reaches the preset process temperature, and the second calendering roller pair 140 can be used to continue the calendering operation, and the first calendering roller pair 130 remains in place, or the shifting device 150 can be used to drive the first calendering roller pair 130 and the second calendering roller pair 140 to perform a reset movement, so that the first calendering roller pair 130 resumes the calendering operation, and the second calendering roller pair 140 suspends the calendering operation. In this way, the calendering equipment 100 does not need to be stopped during the entire online roll change period, and it can continue to calender the glass melt into a glass ribbon, avoiding production losses and improving economic benefits.

[0049] It is worth noting that when the calendering forming equipment 100 operates normally, the distance from the outlet 121 of the feed tube 120 to the gap 131 of the first pair of rollers is the first distance; when the first calendering pair of rollers 130 move away from each other so that the glass molten output from the outlet 121 of the feed tube 120 flows directly to the gap 141 of the second pair of rollers, the distance from the outlet 121 of the feed tube 120 to the gap 141 of the second pair of rollers is the second distance; when the second calendering pair of rollers 140 moves up to the position of the original first calendering pair of rollers 130, the distance from the outlet 121 of the feed tube 120 to the gap 141 of the second pair of rollers is the third distance, and the third distance is equal to the first distance, that is, the preset downstream height of the glass molten flowing out of the outlet 121 of the feed tube 120. It can be seen that during the online roller changing process of the calendering forming equipment 100, the downstream height of the glass melt flowing out of the outlet 121 of the feed pipe 120 first increases and then decreases, and finally returns to the preset downstream height. In this process, the changing downstream height may affect the quality of the glass ribbon, causing the thickness of the glass ribbon to increase, and defects such as uneven thickness and low flatness appear on the plate surface. In this regard, the staff can remove the unqualified glass ribbon according to the on-site conditions to maximize the production while ensuring the product quality. In particular, in other embodiments, the heights of the first calendering roller pair 130 and the second calendering roller pair 140 can be adjusted separately to further accurately adjust the position of the first calendering roller pair 130 on the feed pipe 120 to obtain a better preheating effect of the first calendering roller pair 130; at the same time, it is also convenient to adjust the distance from the outlet 121 of the feed pipe 120 to the gap 141 of the second roller pair according to the temperature and flow rate of the glass liquid on site to obtain a better calendering effect.

[0050] Please refer to Figures 2 to 4 The shifting device 150 includes a lifting mechanism 151, a lifting frame 152, a first translation mechanism 153, and a second translation mechanism 154. The lifting mechanism 151 is installed on the frame 110 and connected to the lifting frame 152. The first translation mechanism 153 and the second translation mechanism 154 are both installed on the lifting frame 152. Specifically, the lifting mechanism 151 is used to synchronously drive the first translation mechanism 153 and the second translation mechanism 154 to rise or fall through the lifting frame 152. The first translation mechanism 153 is connected to the first calendering roller pair 130, and the second translation mechanism 154 is connected to the second calendering roller pair 140. The first translation mechanism 153 can drive the first calendering roller pair 130 to rise and fall during the lifting process, and the second translation mechanism 154 can drive the second calendering roller pair 140 to rise and fall during the lifting process.

[0051] In this embodiment, the driving direction of the first translation mechanism 153 is the same as the driving direction of the second translation mechanism 154. The driving direction of the first translation mechanism 153, the lifting direction of the lifting mechanism 151 and the axial direction of the first calendering roller 130 are perpendicular to each other, so as to realize the online roller changing function and prevent the various components of the calendering forming equipment 100 from interfering with each other during roller changing.

[0052] The lifting frame 152 includes a lifting plate 1521, a guide column 1522 and a guide sleeve 1523. The lifting mechanism 151 is connected to the lifting plate 1521, and the lifting mechanism 151 is used to drive the lifting plate 1521 to rise or fall. The guide column 1522 is connected to the frame 110 and slidably cooperates with the guide sleeve 1523. The lifting plate 1521 is connected to the guide sleeve 1523, and the guide sleeve 1523 can slide relative to the guide column 1522. The guide column 1522 can guide and limit the guide sleeve 1523, thereby limiting the lifting plate 1521 and ensuring the stability of the lifting process of the lifting plate 1521. Specifically, the first translation mechanism 153 and the second translation mechanism 154 are relatively arranged on both sides of the lifting plate 1521 to prevent the first translation mechanism 153 and the second translation mechanism 154 from interfering with each other.

[0053] In this embodiment, the first translation mechanism 153 and the first calendering roller pair 130 are both arranged above the lifting plate 1521, and the second translation mechanism 154 and the second calendering roller pair 140 are both arranged below the lifting plate 1521. The lifting plate 1521 can synchronously drive the first translation mechanism 153, the first calendering roller pair 130, the second translation mechanism 154 and the second calendering roller pair 140 to rise or fall during the lifting process, and the first translation mechanism 153 and the first calendering roller pair 130 arranged above the lifting plate 1521 can facilitate the online roller replacement of the first calendering roller pair 130.

[0054] The first translation mechanism 153 includes a first driving member 1531, a bidirectional lead screw 1532, a first nut 1533, a second nut 1534, a first mounting seat 1535, and a second mounting seat 1536. The first driving member 1531 is mounted on the lifting frame 152 and is in transmission connection with the bidirectional lead screw 1532. The first nut 1533 and the second nut 1534 have opposite rotation directions and both cooperate with the bidirectional lead screw 1532. The first driving member 1531 is used to drive the bidirectional lead screw 1532 to rotate, thereby driving the first nut 1533 and the second nut 1534 to move closer to or farther from each other along the axial direction of the bidirectional lead screw 1532, wherein the axial direction of the bidirectional lead screw 1532 is the driving direction of the first translation mechanism 153. Specifically, the first nut 1533 is connected to the first mounting seat 1535, the second nut 1534 is connected to the second mounting seat 1536, the first calendering roller pair 130 are respectively mounted on the first mounting seat 1535 and the second mounting seat 1536, the first mounting seat 1535 and the second mounting seat 1536 are both slidably matched with the lifting frame 152, and the first nut 1533 and the second nut 1534 can synchronously drive the first calendering roller pair 130 to approach or move away from each other through the first mounting seat 1535 and the second mounting seat 1536 in the process of approaching or moving away from each other. In this process, since the first mounting seat 1535 and the second mounting seat 1536 are both slidably matched with the lifting frame 152, the lifting frame 152 can guide and limit the first mounting seat 1535 and the second mounting seat 1536 to ensure the stability of the movement of the first calendering roller pair 130.

[0055] Furthermore, the first mounting seat 1535 is provided with a first slider (not shown in the figure), the second mounting seat 1536 is provided with a second slider (not shown in the figure), and the lifting plate 1521 of the lifting frame 152 is provided with a guide rail (not shown in the figure) extending along the driving direction of the first translation mechanism 153.

In this embodiment, the transmission screw 1512 is extended in the vertical direction. The second driving member 1511 can drive the lifting frame 152, the first translation mechanism 153 and the second translation mechanism 154 to rise or fall in the vertical direction through the cooperation of the transmission screw 1512 and the third nut 1513.

[0059] Specifically, the first drive device 160 is connected to the first calendering roller 132, and the second drive device is connected to the second calendering roller 133. The first drive device 160 is used to drive the first calendering roller 132 to rotate in one direction, usually clockwise; the second drive device is used to drive the second calendering roller 133 to rotate in another direction, usually counterclockwise, to achieve relative rotation of the first calendering roller pair 130, which is convenient for calendering. Correspondingly, the third drive device 170 is connected to the third calendering roller 142, and the fourth drive device is connected to the fourth calendering roller 143. The third drive device 170 is used to drive the third calendering roller 142 to rotate in one direction, usually clockwise; the fourth drive device is used to drive the fourth calendering roller 143 to rotate in another direction, usually counterclockwise, to achieve relative rotation of the second calendering roller pair 140, which is convenient for calendering.

[0060] Please refer to Figures 5 to 7The first driving device 160 includes a third driving member 161, a universal joint 162 and a quick release mechanism 163. The third driving member 161 is connected to the first calendering roller 132 through the universal joint 162 and the quick release mechanism 163 in turn, and the third driving member 161 can drive the first calendering roller 132 to rotate through the universal joint 162 and the quick release mechanism 163 in turn. Among them, the universal joint 162 is used to realize the power transmission with variable angle, so as to flexibly adjust the power input direction of the third driving member 161, so that the installation position of the third driving member 161 is flexible and changeable, which is conducive to saving space and realizing anti-interference; the quick release mechanism 163 is used to realize the rapid disassembly and assembly of the universal joint 162 and the first calendering roller 132, so as to improve the efficiency of online roller changing.

[0061] The quick release mechanism 163 includes a quick release plug 164 and a quick release socket 165. One of the quick release plug 164 and the quick release socket 165 is connected to the universal joint 162, and the other is connected to the first calendering roller 132. The quick assembly of the quick release plug 164 and the quick release socket 165 realizes the quick installation of the universal joint 162 and the first calendering roller 132. Specifically, the quick-release plug 164 is provided with a plug-in portion 1641, and the quick-release socket 165 is provided with a mating cavity 1651 and a clearance groove 1652 connected to the mating cavity 1651. A support 1653 is provided in the mating cavity 1651. The plug-in portion 1641 is used to extend into the mating cavity 1651 through the clearance groove 1652 to achieve rapid assembly of the quick-release plug 164 and the quick-release socket 165. The plug-in portion 1641 is also used to abut against the support 1653 to apply force to the quick-release socket 165 through the support 1653, thereby achieving a transmission function.

[0062] In this embodiment, the universal joint 162 is connected to the quick release plug 164, and the first calendering roller 132 is connected to the quick release socket 165. The universal joint 162 can apply torque to the first calendering roller 132 through the cooperation of the quick release plug 164 and the quick release socket 165 to drive the first calendering roller 132 to rotate. However, it is not limited to this. In other embodiments, the universal joint 162 can also be connected to the quick release socket 165. In this case, the first calendering roller 132 is connected to the quick release plug 164, and the transmission function can also be realized.

[0063] During the assembly process of the quick-release plug 164 and the quick-release socket 165, firstly, the positions of the plug-in portion 1641 and the clearance groove 1652 are aligned, and the quick-release plug 164 is brought close to the quick-release socket 165, so that the plug-in portion 1641 extends into the matching cavity 1651 through the clearance groove 1652; then, the third driving member 161 is used to drive the quick-release plug 164 to rotate through the universal joint 162, so that the plug-in portion 1641 and the clearance groove 1652 are misaligned, and the plug-in portion 1641 is abutted against the support 1653, so as to complete the assembly; thereafter, the third driving member 161 can drive the first calendering roller 132 to rotate through the universal joint 162, the quick-release plug 164 and the quick-release socket 165 in turn, so as to facilitate calendering molding. On the contrary, during the disassembly process of the quick-release plug 164 and the quick-release socket 165, the third driving member 161 is first used to drive the quick-release plug 164 to rotate in the opposite direction through the universal joint 162, so that the plug-in portion 1641 is separated from the support 1653, and the positions of the plug-in portion 1641 and the clearance groove 1652 correspond to each other; then the quick-release plug 164 is moved away from the quick-release socket 165, so that the plug-in portion 1641 is retracted from the clearance groove 1652 to the matching cavity 1651, and the disassembly is completed. In this way, the assembly process and the disassembly process of the quick-release mechanism 163 are simple and fast, which is convenient for quickly realizing online roller replacement and improving roller replacement efficiency.

[0064] Specifically, the number of the plug-in parts 1641, the clearance grooves 1652 and the support 1653 are all multiple, and the multiple clearance grooves 1652 are distributed in a ring array, and the multiple plug-in parts 1641 are distributed in a ring array. Each clearance groove 1652 is used for a plug-in part 1641 to extend into, and each support 1653 is used to abut against a plug-in part 1641. Multiple plug-in parts 1641 and multiple support 1653 work together to ensure the reliability of the transmission process. In this embodiment, the number of the plug-in parts 1641, the clearance grooves 1652 and the support 1653 are all three, but it is not limited to this. In other embodiments, the number of the plug-in parts 1641, the clearance grooves 1652 and the support 1653 can be four or two, and the number of the plug-in parts 1641, the clearance grooves 1652 and the support 1653 is not specifically limited.

Specifically, after the first calendering roller pair 130 is replaced, the feed pipe 120 is located between the new first calendering roller pair 130. At this time, the high-temperature glass melt in the feed pipe 120 mainly preheats the new first calendering roller pair 130, and the auxiliary heating element performs auxiliary preheating on the first calendering roller pair 130, so as to further shorten the production process recovery time and avoid production loss.

Compared with the prior art, the calendering forming equipment 100 provided by the present invention adopts the first calendering roller pair 130 and the second calendering roller pair 140 arranged in parallel and the shifting device 150 connected to the first calendering roller pair 130 and the second calendering roller pair 140 at the same time, so that the first calendering roller pair 130 can be replaced online without stopping during the roller replacement, thereby ensuring the output.
