Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of glass production, and in particular to a discharging device and glass production equipment. Background Art
[0002] At present, in the glass production process, the incoming molten glass is generally transported to the forming roller by tubular drainage or overflow pull-down. In the tubular drainage method, the molten glass falls too concentratedly to the forming roller, resulting in uneven thickness defects and "cold rib" defects in the rolled glass products; while in the overflow pull-down method, the molten glass overflows through both sides of the overflow trough, flows evenly downward along the tapered part of the overflow trough, and merges together at the lower part of the cone. In this process, the molten glass is prone to a large heat exchange with the air, affecting the temperature of the molten glass, resulting in folding mark defects in the rolled glass products. Summary of the invention
[0003] The applicant has studied the defects existing in glass products formed by rolling by two conveying methods, tubular drainage and overflow pull-down, and found that the glass melt transported to the gap between the forming rollers by tubular drainage has a higher flow rate of the glass melt at the landing point than the glass melt flow rate on both sides of the landing point between the rollers. The flow difference will cause uneven thickness defects in the glass products. Since cooling water is supplied inside the forming rollers, the flow difference problem will cause the glass melt on both sides of the landing point between the rollers to contact the forming rollers less than the glass melt at the landing point, causing a lateral temperature difference in the glass melt, and then causing the "cold rib" defect in the rolled glass products. The glass melt transported to the gap between the forming rollers by overflow pull-down has a temperature difference between its surface temperature and the internal temperature after a large heat exchange occurs when falling. When the glass melt falls into the gap between the rollers, it will form a glass melt material beach with a large temperature difference and alternating doping. After rolling, fold marks will eventually form on the glass products, causing quality defects. Therefore, the quality of glass product molding can be effectively improved by eliminating the flow difference of the molten glass between the forming rollers and the temperature difference between the surface temperature of the molten glass and the internal temperature when the molten glass falls between the rollers.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0037] 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.
[0038] Please refer to Figures 1 to 7 The embodiment of the present invention provides a glass production device 10 for producing glass products. The device can adjust the falling height, falling position and discharge temperature of the glass melt 300 in real time with high adjustment accuracy, improve the rolling and forming effect of the glass products, ensure the quality of the glass products, and improve the yield rate of the glass products.
[0039] It should be noted that the glass production equipment 10 includes a feed channel (not shown), a discharge device 100 and a calendering roller pair 200. The feed channel is used to feed the glass melt 300 into the discharge device 100, and the discharge device 100 is used to feed the glass melt 300 into the gap 210 between the calendering roller pairs 200 to form a material beach in the gap 210. Cooling water circulates inside the calendering roller pairs 200, and the calendering roller pairs 200 are used to roll and cool the glass melt 300 to form a glass product. It should be noted that the glass product can be glass or microcrystalline glass.
[0040] The discharging device 100 includes a position adjustment mechanism 110, a mounting bracket 120, a hopper 130, a temperature adjustment mechanism 140 and a controller 150. The hopper 130 is mounted on the mounting bracket 120. The hopper 130 is used to be arranged above the calendering roller pair 200 to deliver the glass melt 300 to the roller gap 210 of the calendering roller pair 200. In this embodiment, the hopper 130 is detachably connected to the mounting bracket 120 for easy maintenance and cleaning. The position adjustment mechanism 110 is connected to the mounting bracket 120. The position adjustment mechanism 110 is used to adjust the relative position between the hopper 130 and the roller gap 210, so as to adjust the falling height and falling position of the glass melt 300 in real time, so as to avoid the situation that the glass melt 300 flow rate is high at the landing point and the glass melt 300 flow rate is low on both sides of the roller gap due to the concentrated landing point, so as to ensure the flow rate of the glass melt 300 in the roller gap 210 is consistent, so that the glass melt 300 in the roller gap 210 flows through the roller gap for the same time, so as to ensure the uniform thickness of the glass product; it can also avoid the concentrated landing point. The contact time between the molten glass 300 on both sides of the rollers and the rolling rollers 200 is shorter than the contact time between the molten glass 300 and the rolling rollers 200 at the landing point, thereby ensuring that the cooling time of the molten glass 300 in the gap 210 of the rolling rollers 200 equipped with cooling water is the same, thereby ensuring that the temperature distribution of the molten glass 300 in the transverse direction (i.e., the axial direction of the rolling rollers 200) is uniform, preventing the molten glass 300 from forming cold ribs at the junction of the temperature difference, avoiding the defect of obvious boundary lines between the glass on both sides and the glass in the middle on the glass products after rolling, and improving the quality of the glass products. The temperature regulating mechanism 140 is connected to the hopper 130, and the temperature regulating mechanism 140 is used to adjust the temperature of the molten glass 300, thereby adjusting the discharge temperature of the molten glass 300 in real time, ensuring that the temperature of the molten glass 300 falling into the gap 210 of the rolling rollers is always within the preset temperature range, thereby ensuring the calendering molding effect of the glass products. In summary, the discharging device 100 can adjust the falling height, falling position and discharging temperature of the glass melt 300 in real time with high adjustment accuracy, improve the calendering effect of glass products, ensure the quality of glass products, and improve the yield rate of glass products.
[0041] It is worth noting that the controller 150 is electrically connected to the position adjustment mechanism 110 and the temperature adjustment mechanism 140 at the same time, and the controller 150 is used to control the operation of the position adjustment mechanism 110 and the temperature adjustment mechanism 140 to adjust the falling height, falling position and discharge temperature of the glass melt 300 in real time. Specifically, the controller 150 is used to control the position adjustment mechanism 110 to adjust the position of the hopper 130 with an accuracy range of less than or equal to ±0.5 mm, so as to ensure that the hopper 130 can move to an accurate position, thereby improving the rolling and forming effect of the glass product and ensuring the quality of the glass product; the controller 150 is also used to control the temperature adjustment mechanism 140 to adjust the temperature of the glass melt 300 with an accuracy range of less than or equal to ±1 degree Celsius, so as to ensure that the glass melt 300 reaches an accurate temperature, thereby improving the rolling and forming effect of the glass product and ensuring the quality of the glass product.
[0042] Furthermore, the controller 150 is provided with a human-machine interaction platform, and the human-machine interaction platform is used to realize the human-machine interaction function of the discharging device 100. On the one hand, the human-machine interaction platform is used for the user to input control commands, and the controller 150 is used to control the position adjustment mechanism 110 to adjust the position of the hopper 130 according to the control command, thereby adjusting the falling height and falling position of the glass melt 300, and the controller 150 is also used to control the temperature adjustment mechanism 140 to adjust the temperature of the hopper 130 according to the control command, thereby adjusting the temperature of the glass melt 300. On the other hand, the position adjustment mechanism 110 is used to feed back the position information of the hopper 130 to the controller 150, and the controller 150 is used to analyze and process the position information, and display the obtained operating parameters on the human-machine interaction platform; the temperature adjustment mechanism 140 is used to feed back the temperature information of the hopper 130 to the controller 150, and the controller 150 is used to analyze and process the temperature information, and display the obtained operating parameters on the human-machine interaction platform.
[0043] The position adjustment mechanism 110 includes a base 111, a first drive assembly 112, a translation stage 113, a second drive assembly 114, a sliding stage 115, a third drive assembly 116 and a moving frame 117. The first drive assembly 112 is mounted on the base 111 and connected to the translation stage 113. The first drive assembly 112 is used to drive the translation stage 113 to move along a first direction. The second drive assembly 114 is mounted on the translation stage 113 and connected to the sliding stage 115. The second drive assembly 114 is used to drive the sliding stage 115 to move along a second direction. The third drive assembly 116 is mounted on the sliding stage 115 and connected to the moving frame 117. The moving frame 117 is connected to the mounting bracket 120. The third drive assembly 116 is used to drive the mounting bracket 120 to move along a third direction through the moving frame 117. The controller 150 is electrically connected to the first drive assembly 112 , the second drive assembly 114 and the third drive assembly 116 at the same time to respectively control the displacement of the mounting bracket 120 in the first direction, the second direction and the third direction, thereby accurately adjusting the position of the hopper 130 .
[0044] In this embodiment, the first direction, the second direction and the third direction are perpendicular to each other, wherein the first direction and the third direction are both located on a horizontal plane, and the second direction is located on a vertical plane. Specifically, the first drive assembly 112 can sequentially drive the mounting bracket 120 to translate along the first direction through the translation platform 113, the second drive assembly 114, the sliding platform 115, the third drive assembly 116 and the moving frame 117, the second drive assembly 114 can sequentially drive the mounting bracket 120 to rise and fall along the second direction through the sliding platform 115, the third drive assembly 116 and the moving frame 117, and the third drive assembly can drive the mounting bracket 120 to translate along the third direction through the moving frame 117. The first drive assembly 112, the second drive assembly 114 and the third drive assembly 116 work together to enable the mounting bracket 120 to move to any coordinate in the three-dimensional space coordinate system, thereby enabling the hopper 130 to move to any coordinate in the three-dimensional space coordinate system, thereby improving the position adjustment accuracy of the hopper 130, and further adjusting the falling height and falling position of the glass melt 300, wherein the falling height of the glass melt 300 is adjusted by the second drive assembly 114, and the falling position of the glass melt 300 is adjusted jointly by the first drive assembly 112 and the third drive assembly 116.
[0045] In this embodiment, the first drive component 112 drives the translation table 113 to move in the first direction at a speed less than or equal to 5 mm / s, the second drive component 114 drives the sliding table 115 to move in the second direction at a speed less than or equal to 5 mm / s, and the third drive component 116 drives the mounting bracket 120 to move in the third direction through the motion frame 117 at a speed less than or equal to 10 mm / s, so as to ensure the movement accuracy of the hopper 130.
[0046] The first drive assembly 112 includes a first drive motor 1121, a first screw rod 1122 and a first nut sleeve 1123. The controller 150 is electrically connected to the first drive motor 1121, the first drive motor 1121 is mounted on the base 111, and is connected to the first screw rod 1122, the first screw rod 1122 is threadedly matched with the first nut sleeve 1123, the first nut sleeve 1123 is fixedly connected to the translation platform 113, and the axial direction of the first screw rod 1122 is the first direction. Specifically, in the process of the first drive assembly 112 driving the translation platform 113 to move, the first drive motor 1121 is started, and the first drive motor 1121 drives the first screw rod 1122 to rotate around its axial direction. In this process, since the first screw rod 1122 is threadedly matched with the first nut sleeve 1123, the first nut sleeve 1123 will translate along the axial direction of the first screw rod 1122, thereby driving the translation platform 113 to translate along the first direction.
[0047] In this embodiment, the base 111 is provided with a first slide rail 1111, and the translation stage 113 is provided with a first slider (not shown), the first slider is slidably matched with the first slide rail 1111, and the extension direction of the first slide rail 1111 is the first direction. Specifically, the first slider can slide relative to the first slide rail 1111, and the first slide rail 1111 can guide and limit the first slider to ensure that the first slider slides along the first direction, thereby ensuring that the translation stage 113 slides along the first direction, and improving the sliding stability of the translation stage 113.
[0048] Specifically, there are two first slide rails 1111 and two first sliders, and the two first slide rails 1111 are relatively arranged at the two ends of the base 111. Each first slide rail 1111 is slidably matched with a first slider. The two first slide rails 1111 and the two first sliders work together to further improve the sliding stability of the translation platform 113.
[0049] Further, the base 111 is provided with a first stop block 1112 and a second stop block 1113 at intervals along the first direction. The first stop block 1112 and the second stop block 1113 selectively abut against the translation stage 113 to limit the limit position of the translation stage 113, prevent the translation stage 113 from being separated from the base 111, and avoid damage to the entire discharging device 100. Specifically, the number of the limit positions of the translation stage 113 is two. When the first driving component 112 drives the translation stage 113 to move to abut against the first stop block 1112, the first stop block 1112 stops the translation stage 113 to limit one limit position of the translation stage 113; when the first driving component 112 drives the translation stage 113 to move to abut against the second stop block 1113, the second stop block 1113 stops the translation stage 113 to limit another limit position of the translation stage 113.
[0050] In this embodiment, an encoder and a brake are provided in the first drive motor 1121, and both the encoder and the brake are electrically connected to the controller 150. The encoder is used to feed back the position information of the hopper 130 to the controller 150 when the first drive motor 1121 drives the hopper 130 to move, and the controller 150 is used to analyze and process the position information, and display the obtained operating parameters on the human-computer interaction platform; the controller 150 is used to control the first drive motor 1121 to stop rotating when the hopper 130 moves to a preset position, and control the brake to lock the rotor of the first drive motor 1121, so that the rotor stops rotating in time, and prevents the rotor from continuing to rotate under the inertia of the load, so as to ensure the accuracy of the position adjustment of the hopper 130.
[0051] In this embodiment, the output shaft of the first drive motor 1121 is directly connected to the first screw rod 1122 through a coupling, and the rotation speed of the output shaft is equal to the rotation speed of the first screw rod 1122. However, this is not limited to this, and in other embodiments, the output shaft of the first drive motor 1121 can also be connected to the first screw rod 1122 through a reducer to reduce the rotation speed, increase the torque, and ensure the stability of the rotation of the first screw rod 1122.
[0052] In this embodiment, the specific structures of the second drive assembly 114 and the third drive assembly 116 are the same as the specific structures of the first drive assembly 112, and are not described in detail here. Further, there are two first drive assemblies 112, which are relatively arranged at the two ends of the base 111, and the two first drive assemblies 112 move synchronously; there are four second drive assemblies 114, which are arranged in a rectangular array on the translation stage 113, and the four second drive assemblies 114 move synchronously; there is one third drive assembly 116, which is arranged in the middle of the sliding stage 115. However, it is not limited to this. In other embodiments, the number of first drive components 112 can also be one, in which case the first drive component 112 is disposed in the middle of the base 111; the number of second drive components 114 can also be two, in which case the two second drive components 114 are relatively disposed on both sides of the sliding table 115, and the two second drive components 114 move synchronously; the number of third drive components 116 can also be two, and the two third drive components 116 are disposed side by side on the sliding table 115, and the two third drive components 116 move synchronously; there is no specific limitation on the number of first drive components 112, second drive components 114 and third drive components 116.
[0053] It is worth noting that the base 111 is provided with a vertical plate 1114 extending along the second direction, and the vertical plate 1114 is provided with a third stop block 1115 and a fourth stop block 1116 at intervals in the second direction. The sliding table 115 is extended to provide a limit block 1151, and the limit block 1151 is arranged between the third stop block 1115 and the fourth stop block 1116.

Specifically, the number of the extreme positions of the sliding table 115 is two. When the second driving component 114 drives the sliding table 115 to move to the point where the limit block 1151 abuts against the third stop block 1115, the third stop block 1115 stops the limit block 1151 to limit an extreme position of the sliding table 115; when the second driving component 114 drives the sliding table 115 to move to the point where the limit block 1151 abuts against the fourth stop block 1116, the fourth stop block 1116 stops the limit block 1151 to limit another extreme position of the sliding table 115.
[0054] In this embodiment, the sliding platform 115 is provided with a second slide rail 1152, and the moving frame 117 is provided with a second slider (not shown), the second slider is slidably matched with the second slide rail 1152, and the extension direction of the second slide rail 1152 is the third direction. Specifically, the second slider can slide relative to the second slide rail 1152, and the second slide rail 1152 can guide and limit the second slider to ensure that the second slider slides along the third direction, thereby ensuring that the moving frame 117 slides along the third direction, and improving the sliding stability of the moving frame 117.
[0055] Specifically, there are two second slide rails 1152 and two second sliders, and the two second slide rails 1152 are relatively arranged at the two ends of the sliding platform 115. Each second slide rail 1152 is slidably matched with a second slider. The two second slide rails 1152 and the two second sliders work together to further improve the sliding stability of the moving frame 117.
[0056] Furthermore, the sliding platform 115 is provided with a fifth stop block 1153 and a sixth stop block 1154 at intervals along the third direction.

Specifically, the number of the limit positions of the moving frame 117 is two. When the first driving component 112 drives the moving frame 117 to abut against the fifth stop block 1153, the fifth stop block 1153 stops the moving frame 117 to limit one limit position of the moving frame 117; when the first driving component 112 drives the moving frame 117 to abut against the sixth stop block 1154, the sixth stop block 1154 stops the moving frame 117 to limit the other limit position of the moving frame 117.
