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

[0034] 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.

[0035] Please refer to Figure 1 The embodiment of the present invention provides a glass rolling production line 10 for producing microcrystalline glass. The glass rolling production line 10 can effectively and quickly adjust the flow rate of the glass melt 500 to ensure that the glass melt 500 is evenly distributed, which is beneficial to subsequent rolling and molding, reduces glass defects, ensures product quality, and improves production stability.

[0036] The glass rolling production line 10 includes a feed channel 200, a hopper 300, a rolling roller pair 400 and a flow regulating fixture 100. The feed channel 200 is used to feed the glass melt 500 into the hopper 300, and the hopper 300 is used to feed the glass melt 500 into the rolling roller pair 400 in a waterfall shape, so as to converge in the roller gap 410 of the rolling roller pair 400 to form a material beach, and the rolling roller pair 400 is used to extrude and cool the glass melt 500 to form a microcrystalline glass. Specifically, the flow regulating fixture 100 is installed on the discharge nozzle 310 of the hopper 300. The flow regulating fixture 100 is used to clamp and limit the discharge nozzle 310 to improve the expansion and deformation of the discharge nozzle 310, so that the discharge nozzle 310 is restored to a preset nozzle shape and nozzle size, thereby adjusting the flow of the glass melt 500 flowing out of the discharge nozzle 310, ensuring that the glass melt 500 is evenly distributed and improving product quality.

[0037] Please refer to Figures 2 to 6The flow regulating fixture 100 includes a first clamping plate 110, a second clamping plate 120, a connecting piece 130 and a plurality of tension adjusting pieces 140. The first clamping plate 110 is connected to the second clamping plate 120 through the connecting piece 130, and the connecting piece 130 is used to realize a detachable connection between the first clamping plate 110 and the second clamping plate 120, so as to facilitate the installation of the flow regulating fixture 100 on the discharge nozzle 310 or removal from the discharge nozzle 310. Specifically, the discharge nozzle 310 of the hopper 300 is flat so that the glass melt 500 flowing out of the discharge nozzle 310 is in a waterfall shape. The first clamp 110 and the second clamp 120 are used to clamp outside the discharge nozzle 310. Under the action of the connecting piece 130, the first clamp 110 and the second clamp 120 are respectively clamped on both sides of the discharge nozzle 310 to fix the relative positions of the first clamp 110 and the second clamp 120 and the discharge nozzle 310 to prevent the first clamp 110 and the second clamp 120 from accidentally detaching from the discharge nozzle 310.

[0038] Furthermore, a plurality of tension adjusting members 140 can be movably mounted on the first clamp plate 110 and / or the second clamp plate 120, and are spaced apart along the length direction of the first clamp plate 110 and the second clamp plate 120. The length direction of the first clamp plate 110 and the second clamp plate 120 is the width direction of the discharge nozzle 310. The tension adjusting members 140 are used to abut against the discharge nozzle 310. The tension adjusting members 140 can move relative to the first clamp plate 110 or the second clamp plate 120 under the action of external force to apply pressure to the discharge nozzle 310, compressing and deforming the discharge nozzle 310 inward, thereby improving the expansion deformation of the discharge nozzle 310, and effectively and quickly adjusting the flow rate of the glass melt 500. Multiple tension adjustment parts 140 work together to compress and deform different positions in the width direction of the discharge nozzle 310, and the amount of compression deformation varies (determined according to the actual expansion deformation at different positions of the discharge nozzle 310), thereby ensuring that the glass melt 500 is evenly distributed, facilitating subsequent calendering and molding, reducing glass defects, ensuring product quality, and improving production stability.

[0039] It should be noted that during the long-term operation of the glass rolling production line 10, since the hopper 300 is always in contact with the high-temperature glass melt 500, the discharge nozzle 310 of the hopper 300 expands and deforms under the action of long-term thermal expansion and contraction. Since the discharge nozzle 310 is flat and has a large width, the expansion deformation of the discharge nozzle 310 in its width direction is prone to be uneven, that is, the expansion deformation of some positions on the discharge nozzle 310 is more serious, while the expansion deformation of some positions is relatively slight. Therefore, in the present invention, a plurality of tension adjusting members 140 are arranged at intervals along the width direction of the discharge nozzle 310, so that the plurality of tension adjusting members 140 correspond to different positions of the discharge nozzle 310 respectively, and the plurality of tension adjusting members 140 are arranged independently of each other, and the staff can adaptively adjust the plurality of tension adjusting members 140 according to the degree of expansion deformation at different positions on the discharge nozzle 310, that is, the tension adjusting members 140 at the positions with more serious expansion deformation have a larger compression deformation on the discharge nozzle 310, and the tension adjusting members 140 at the positions with less expansion deformation have a smaller compression deformation on the discharge nozzle 310, so as to ensure that the caliber size of the discharge nozzle 310 in the width direction is uniform, so as to further make the flow distribution of the glass melt 500 flowing out of the discharge nozzle 310 uniform, which is beneficial to the subsequent calendering molding.

[0040] In this embodiment, the tension adjusting member 140 is movably mounted on the first clamping plate 110 and the second clamping plate 120 at the same time, wherein the plurality of tension adjusting members 140 include a plurality of first tension adjusting members 141 and a plurality of second tension adjusting members 142, the first tension adjusting member 141 is movably mounted on the first clamping plate 110, the second tension adjusting member 142 is movably mounted on the second clamping plate 120, and each first tension adjusting member 141 is aligned with a second tension adjusting member 142. Specifically, a plurality of first tension adjusting members 141 and a plurality of second tension adjusting members 142 are respectively arranged on both sides of the discharge nozzle 310, and each first tension adjusting member 141 corresponds to a position of a second tension adjusting member 142, so as to ensure that different positions on both sides of the discharge nozzle 310 can be compressed and deformed, further improving the recovery effect of the discharge nozzle 310, thereby realizing effective and rapid adjustment of the flow rate of the glass melt 500.

[0041] Furthermore, the spacing between two adjacent first tension adjustment members 141 ranges from 40mm to 50mm, and correspondingly, the spacing between two adjacent second tension adjustment members 142 ranges from 40mm to 50mm. A reasonable spacing between two adjacent first tension adjustment members 141 and a reasonable spacing between two adjacent second tension adjustment members 142 can effectively improve the adjustment accuracy, making it easier to perform compression deformation on different positions on both sides of the discharge nozzle 310.

[0042] Preferably, the first tension adjusting member 141 and the second tension adjusting member 142 are both bolts, and the materials of the first tension adjusting member 141 and the second tension adjusting member 142 can be selected from high temperature resistant and corrosion resistant stainless steel. The first clamping plate 110 is provided with a first threaded hole 111, and the first tension adjusting member 141 is threadedly matched with the first threaded hole 111; the first tension adjusting member 141 can be tightened relative to the first threaded hole 111 to push the first side wall of the discharge nozzle 310 inward, thereby achieving compression deformation of the first side wall; the first tension adjusting member 141 can also be loosened relative to the first threaded hole 111 to loosen the first side wall of the discharge nozzle 310, reduce the amount of compression deformation of the first side wall, or even cancel the compression deformation of the first side wall. The second clamping plate 120 is provided with a second threaded hole 121, and the second tension adjusting member 142 is threadedly matched with the second threaded hole 121; the second tension adjusting member 142 can be tightened relative to the second threaded hole 121 to push the second side wall of the discharge nozzle 310 inward, thereby realizing compression deformation of the second side wall; the second tension adjusting member 142 can also be loosened relative to the second threaded hole 121 to loosen the second side wall of the discharge nozzle 310, reduce the amount of compression deformation of the second side wall, or even cancel the compression deformation of the second side wall.

[0043] In this embodiment, a plurality of first tension adjustment members 141 and a plurality of second tension adjustment members 142 are respectively arranged at intervals on both sides of the discharge nozzle 310, so that multi-point adjustment of the discharge nozzle 310 can be achieved by loosening or tightening different first tension adjustment members 141 and second tension adjustment members 142, so as to control the uniformity of the caliber size of the discharge nozzle 310, thereby fine-tuning the discharge flow distribution of the glass melt 500, ensuring that the glass melt 500 is evenly distributed, and quickly and effectively adjusting the flow size of the glass melt 500.

[0044] The first clamping plate 110 includes a first connecting portion 112, a first clamping portion 113, and a second connecting portion 114 connected in sequence. The first connecting portion 112 and the second connecting portion 114 are disposed oppositely at two ends of the first clamping portion 113, and a plurality of first tension adjusting members 141 are installed at intervals on the first clamping portion 113. The second clamping plate 120 includes a third connecting portion 122, a second clamping portion 123, and a fourth connecting portion 124 connected in sequence. The third connecting portion 122 and the fourth connecting portion 124 are disposed oppositely at two ends of the second clamping portion 123, and a plurality of second tension adjusting members 142 are installed at intervals on the second clamping portion 123. Specifically, the connecting member 130 includes a first connecting member 131 and a second connecting member 132. The first connecting part 112 is connected to the third connecting part 122 through the first connecting member 131, and the second connecting part 114 is connected to the fourth connecting part 124 through the second connecting member 132. The discharge nozzle 310 is clamped between the first clamping part 113 and the second clamping part 123. The first clamping part 113 and the second clamping part 123 work together to fix the relative position of the discharge nozzle 310 and the flow regulating fixture 100.

[0045] Furthermore, the first clamping plate 110 and the second clamping plate 120 are both arranged in a broken line shape, that is, the first connecting portion 112 and the second connecting portion 114 are both bent relative to the first clamping portion 113, and the third connecting portion 122 and the fourth connecting portion 124 are both bent relative to the second clamping portion 123. Specifically, the spacing between the first connecting portion 112 and the third connecting portion 122 is equal to the spacing between the second connecting portion 114 and the fourth connecting portion 124, and is smaller than the spacing between the first clamping portion 113 and the second clamping portion 123. By designing the first clamping plate 110 and the second clamping plate 120 in a broken line shape, it is convenient to assemble and disassemble the flow regulating fixture 100, so that the force points and force areas of the first clamping plate 110 and the second clamping plate 120 are more accurate, thereby preventing the discharge nozzle 310 from expanding and deforming, and also facilitating the first clamping plate 110 and the second clamping plate 120 to fit closely, thereby improving the stability of clamping. In addition, the overall weight and production cost of the flow regulating fixture 100 can be effectively reduced.

[0046] In this embodiment, the first connection portion 112 and the third connection portion 122 are arranged in parallel and spaced apart, the first clamping portion 113 and the second clamping portion 123 are arranged in parallel and spaced apart, the second connection portion 114 and the fourth connection portion 124 are arranged in parallel and spaced apart, and the spacing between the first connection portion 112 and the third connection portion 122 is equal to the spacing between the second connection portion 114 and the fourth connection portion 124, and is smaller than the spacing between the first clamping portion 113 and the second clamping portion 123. Further, the number of the first connection member 131 and the second connection member 132 are both two, and the two first connection members 131 and the two second connection members 132 work together to further improve the connection strength of the first clamping plate 110 and the second clamping plate 120 to ensure the clamping effect.

[0047] Preferably, the first connecting member 131 includes bolts and nuts, and the materials of the bolts and nuts can be selected from high temperature resistant and corrosion resistant stainless steel. During the installation process of the flow regulating fixture 100, the bolts are passed through the first connecting portion 112 and the third connecting portion 122 in sequence, and tightened relative to the nuts to fix the relative positions of the first connecting portion 112 and the third connecting portion 122, thereby fixing the relative positions of the first clamping plate 110 and the second clamping plate 120. Accordingly, the specific structure of the second connecting member 132 is the same as the specific structure of the first connecting member 131, and will not be repeated here.

[0048] In this embodiment, the first clamping plate 110 and the second clamping plate 120 are respectively clamped on both sides of the discharge nozzle 310, and the first clamping plate 110 and the second clamping plate 120 are connected by the first connecting member 131 and the second connecting member 132. The distance between the first clamping plate 110 and the second clamping plate 120 can be adjusted by tightening or loosening the first connecting member 131 and the second connecting member 132, so as to adjust the initial positions of the first tension adjusting member 141 and the second tension adjusting member 142, and ensure that the first tension adjusting member 141 and the second tension adjusting member 142 are respectively abutted against the two sides of the discharge nozzle 310, which is conducive to realizing uniform and stable discharge of the discharge nozzle 310.

[0049] Preferably, the material of the first splint 110 and the second splint 120 can be selected from refractory materials (molybdenum, tungsten, chromium, etc.) or heat-resistant materials (silicon carbide, boron nitride, etc.), the hardness and rigidity of the first splint 110 and the second splint 120 are greater than the hardness and rigidity of the discharge nozzle 310, and the thermal expansion coefficients of the first splint 110 and the second splint 120 are smaller than the thermal expansion coefficient of the discharge nozzle 310, and the thermal expansion and contraction deformation of the first splint 110 and the second splint 120 at the same temperature are significantly smaller than the thermal expansion and contraction deformation of the discharge nozzle 310, so as to prevent the first splint 110 and the second splint 120 from deforming under the reaction force of the first tension adjustment member 141 and the second tension adjustment member 142, and ensure that the compression deformation of the discharge nozzle 310 by the first tension adjustment member 141 and the second tension adjustment member 142 is stable and reliable, thereby ensuring that the glass melt 500 is evenly distributed, which is beneficial to subsequent calendering molding and product quality.

[0050] The first clamping portion 113 is provided with a plurality of first reinforcing ribs 115, which are arranged in parallel and spaced apart along the length direction of the first clamping portion 113, and the plurality of first reinforcing ribs 115 work together to improve the structural strength of the first clamping portion 113 and prevent the first clamping portion 113 from deforming during the flow regulation process. The second clamping portion 123 is provided with a plurality of second reinforcing ribs 125, which are arranged in parallel and spaced apart along the length direction of the second clamping portion 123, and the plurality of second reinforcing ribs 125 work together to improve the structural strength of the second clamping portion 123 and prevent the second clamping portion 123 from deforming during the flow regulation process. Specifically, each first reinforcing rib 115 is aligned with a second reinforcing rib 125 for ease of production and processing.

[0051] In this embodiment, the number of first tension adjusting members 141 is equal to the number of first reinforcing ribs 115 plus one, and each first reinforcing rib 115 is disposed between two adjacent first tension adjusting members 141. The first reinforcing rib 115 is used to prevent the first clamping portion 113 from being deformed under the reaction force when the first tension adjusting member 141 adjusts the flow rate. The number of second tension adjusting members 142 is equal to the number of second reinforcing ribs 125 plus one, and each second reinforcing rib 125 is disposed between two adjacent second tension adjusting members 142. The second reinforcing rib 125 is used to prevent the second clamping portion 123 from being deformed under the reaction force when the second tension adjusting member 142 adjusts the flow rate.

[0052] Preferably, the first reinforcing rib 115 is extended along the width direction of the first clamping portion 113 and is located on a side of the first clamping portion 113 away from the second clamping portion 123, so as to facilitate processing and not affect the operation of the first tension adjusting member 141. The second reinforcing rib 125 is extended along the width direction of the second clamping portion 123 and is located on a side of the second clamping portion 123 away from the first clamping portion 113, so as to facilitate processing and not affect the operation of the second tension adjusting member 142.

[0053] Preferably, the materials of the first reinforcing rib 115 and the second reinforcing rib 125 can be selected from high temperature resistant and corrosion resistant stainless steel. The first reinforcing rib 115 is fixed to the first clamping portion 113 by welding to improve the strength and rigidity of the first clamping portion 113, to prevent it from expanding and deforming, and at the same time has a certain heat preservation performance (the first reinforcing rib 115 is welded to the first clamping portion 113, which is equivalent to increasing the thickness of a part of the first clamping portion 113, and the thicker first clamping portion 113 can play a role in isolating heat and achieve a heat preservation function), reducing heat loss. The second reinforcing rib 125 is fixed to the second clamping portion 123 by welding to improve the strength and rigidity of the second clamping portion 123, to prevent it from expanding and deforming, and at the same time has a certain heat preservation performance (the second reinforcing rib 125 is welded to the second clamping portion 123, which is equivalent to increasing the thickness of a part of the second clamping portion 123, and the thicker second clamping portion 123 can play a role in isolating heat and achieve a heat preservation function), reducing heat loss.

[0054] Preferably, the first clamping part 113 is further provided with a plurality of groups of first insulation clamping blocks 116, and each first reinforcing rib 115 is arranged between two adjacent groups of first insulation clamping blocks 116; the second clamping part 123 is further provided with a plurality of groups of second insulation clamping blocks 126, and each second reinforcing rib 125 is arranged between two adjacent groups of second insulation clamping blocks 126. There is a gap between the first insulation clamping block 116 and the first clamping part 113, and the gap is used to fill insulation cotton, and the first insulation clamping block 116 is used to press and fix the insulation cotton outside the first clamping part 113; there is a gap between the second insulation clamping block 126 and the second clamping part 123, and the gap is used to fill insulation cotton, and the second insulation clamping block 126 is used to press and fix the insulation cotton outside the second clamping part 123; the insulation cotton is used to insulate the discharge nozzle 310 to reduce its heat loss, ensure the uniformity of the temperature distribution of the glass melt 500 in the discharge nozzle 310, and improve the product quality. Specifically, the material of the first thermal insulation clamp block 116 and the second thermal insulation clamp block 126 can be selected from high temperature resistant and corrosion resistant stainless steel.

[0055] In this embodiment, the number of first tension adjusting members 141 is the same as the number of groups of first heat-insulating clamping blocks 116; the number of each group of first heat-insulating clamping blocks 116 is two, and each group of two first heat-insulating clamping blocks 116 is arranged at intervals, and each first tension adjusting member 141 is arranged between a group of two first heat-insulating clamping blocks 116; the number of each group of second heat-insulating clamping blocks 126 is two, and each group of two second heat-insulating clamping blocks 126 is arranged at intervals, and each second tension adjusting member 142 is arranged between a group of two second heat-insulating clamping blocks 126. In this way, the first heat-insulating clamping block 116 will not affect the operation of the first tension adjusting member 141, and the second heat-insulating clamping block 126 will not affect the operation of the second tension adjusting member 142, and the heat-insulating effect is further improved, and the temperature distribution uniformity of the glass melt 500 in the discharge nozzle 310 is improved.

[0057] Furthermore, a supporting portion 118 is provided at the free end of the boss 117, and an anti-slip portion 128 is provided at the opening of the limiting groove 127. The anti-slip portion 128 is used to abut against the supporting portion 118 when the boss 117 slides to the extreme position relative to the limiting groove 127, so as to prevent the first clamping plate 110 and the second clamping plate 120 from accidentally detaching, thereby ensuring the reliability of the flow regulating clamp 100.

[0058] In this embodiment, the number of the bosses 117 and the limiting grooves 127 are both two, and the two bosses 117 are relatively arranged at the two ends of the first clamping plate 110, and each boss 117 is slidably matched with a limiting groove 127, one of the bosses 117 is arranged between the first connecting portion 112 and the first clamping portion 113, and the other boss 117 is arranged between the second connecting portion 114 and the first clamping portion 113.

[0059] In the present invention, a dynamic experiment is conducted using silicone oil to simulate a glass melt 500. The flow rate of silicone oil and its error as well as the temperature loss are tested with and without the flow regulating fixture 100. The results are as follows:

[0063]

[0064] According to Table 1, the discharge flow rate value of silicone oil (simulating glass melt 500) of the discharge nozzle 310 after using the flow regulating fixture 100 is closer to the set value than the discharge flow rate value of silicone oil (simulating glass melt 500) of the discharge nozzle 310 when the flow regulating fixture 100 is not used, and the error is also smaller. The stable pulling amount is more conducive to glass molding and ensures product quality.

[0065] According to Table 2, the maximum temperature of the silicone oil (simulating the glass melt 500) after using the flow regulating fixture 100 is higher than that of the silicone oil (simulating the glass melt 500) when the flow regulating fixture 100 is not used, and is greater than the temperature setting value. In addition, the temperature loss is zero, the thermal insulation effect is better, and it is more conducive to glass forming.

[0066] In the flow regulating fixture 100 provided in the embodiment of the present invention, the first clamping plate 110 is connected to the second clamping plate 120 through a connecting piece 130. The first clamping plate 110 and the second clamping plate 120 are used to be clamped outside the discharge nozzle 310 of the hopper 300. A plurality of tension adjusting members 140 are movably mounted on the first clamping plate 110 and / or the second clamping plate 120 and are arranged at intervals along the length direction of the first clamping plate 110 and the second clamping plate 120. The tension adjusting members 140 are used to abut against the discharge nozzle 310. Compared with the prior art, the flow regulating fixture 100 provided in the present invention can effectively and quickly adjust the flow of the glass melt 500, ensure that the glass melt 500 is evenly distributed, facilitate subsequent calendering molding, reduce glass defects, ensure product quality, and improve production stability because it adopts the first clamping plate 110 and the second clamping plate 120 clamped outside the discharge nozzle 310 and the plurality of tension adjusting members 140 installed on the first clamping plate 110 and / or the second clamping plate 120. The glass rolling production line 10 has good product quality and high yield rate.
