Description

Technical Field

[0001] The invention belongs to the technical field of substrate glass production, and in particular relates to a substrate glass forming traction mechanism and an annealing furnace. Background Art

[0002] The overflow method is a widely used technology in the production of substrate glass, used to manufacture high-generation substrate glass. The main process of producing substrate glass using the overflow method is as follows: high-temperature molten glass flows from the glass melting furnace, undergoes clarification and homogenization, and then flows into an overflow brick device. At the bottom of the overflow brick, the hot glass melts and is stretched into a continuous glass sheet by a pulling device. This sheet is then rapidly cooled and solidified by a cooling device to become the substrate glass. The entire process requires strict control of process parameters such as temperature and pressure, while also ensuring normal equipment operation and maintenance.

[0003] The overflow method uses a side-drawing system to gradually cool the hot molten glass into a continuous sheet. During this process, the traction roller is a key component in stretching the glass sheet. These rollers provide traction, support, and fixation, as well as temperature transfer, ensuring the production of high-quality substrate glass that meets production requirements. They also need to be heat-resistant, wear-resistant, and replaceable to meet production process requirements. The traction rollers contact the hot glass sheet and apply appropriate force to pull the molten glass into a continuous sheet. They provide stable support and fixation to prevent shaking, deformation, or breakage during the traction process, ensuring consistent sheet quality. Because the substrate glass production process typically operates at high temperatures, the traction rollers must possess adequate thermal conductivity to quickly remove heat from the glass sheet, enabling rapid cooling and solidification. They must also be heat-resistant and wear-resistant to withstand the high-temperature operating environment and the friction of the molten glass on their surfaces, ensuring a long service life.

[0004] However, traditional traction rollers present several problems during use. First, due to the characteristics of high-temperature molten glass, the traction rollers operate at high temperatures. Under these conditions, the temperature of the incoming glass fluctuates during use, causing changes in the thickness of the glass sheet and squeezing the traction rollers on both sides. The protective structure on the outside of the rollers has a small contact area with the end face of the annealing furnace, and the counterweight is light and loosely fixed, resulting in a lack of stable support and roller shaking. The shaking or deformation of the rollers during the stretching process of the substrate glass has a reverse effect on the substrate glass, adversely affecting its quality.

[0005] Secondly, the traditional annealing furnace structure is an integrated structure, with the end plate fixed on the furnace body. The end plate has an oblong hole, and the outer long axis of the traction roller extends from the oblong hole. The traction roller is installed inside the furnace body as a whole. If the roller body is to be installed or replaced, the end plate needs to be completely removed. Due to the limitations of the furnace body structure, this replacement method is time-consuming and labor-intensive, and there are safety hazards. At the same time, it will prolong the downtime of the production line, which will have a negative impact on production efficiency and output. Summary of the Invention

[0029] like Figure 1-7As shown, the present invention provides a substrate glass forming traction mechanism, comprising: a frame 10, two traction rollers 20 and an adjustable support mechanism, wherein the frame 10 is open at the top and bottom, and at both ends of the frame 10 are provided with at least one combination plate 11, and the combination plate 11 is provided with an arc-shaped opening 114 and an arc-shaped opening 2 115; the arc-shaped opening 114 and the arc-shaped opening 2 115 are symmetrically distributed, and the spacing between them gradually increases from top to bottom; wherein, the two ends of one traction roller 20 respectively pass through the two arc-shaped openings 114, and the two ends of the other traction roller 20 respectively pass through the two arc-shaped openings 114. The two traction rollers 20 are respectively driven and connected to the driving equipment through the two arc-shaped openings 115; the adjustable support mechanism includes four arms 30, and a plurality of counterweights 33 with adjustable positions are provided on the arms 30. Each composite plate 11 is connected to the two arms 30 for fixed-axis rotation, and one end of each arm 30 away from the counterweight 33 is connected to the end of the two traction rollers 20 for rotation. By adjusting the position of the counterweight 33 on the arm 30 and / or the increase or decrease of the number of counterweights, the clamping force of the traction rollers 20 on the glass plate 50 on both sides can be changed.

[0030] Compared with the prior art, the substrate glass forming traction mechanism provided by the present invention has two arc-shaped openings 114 on the two combined plates 11 at both ends of the frame 10 as a group, which are used to support the two ends of a traction roller 20, and two arc-shaped openings 115 on the two combined plates 11 at both ends of the frame 10 as a group, which are used to support the two ends of another traction roller 20. The two traction rollers 20 pull the glass sheet 50 downward by friction; the two arms 30 rotatably connected at both ends of each traction roller 20 are connected with the fixed axis rotation connection with the combined plate 11 as the rotation center, forming a The lever structure presses down one end of the support arm 30 through the counterweight block 33, so that the two traction rollers 20 have a force to move closer to each other, which can continuously and stably support the traction rollers 20 and continuously clamp the glass plate 50, effectively reducing the shaking and deformation of the traction rollers 20 and improving the quality stability of the substrate glass; the torque can also be changed by changing the position of the counterweight on the support arm 30 to achieve the adjustment of the clamping force of the traction rollers 20 to meet the needs of traction of substrate glass under working conditions such as different specifications of substrate glass, different temperature fields and different rotation speeds of the traction rollers 20.

[0031] In this embodiment, the driving device is a motor (not shown in the figure). The driving device is installed in a manner such that it is fixed on a platform that moves in a plane coordinate system to meet the need of adjusting the clamping force of the traction roller 20. After the traction roller 20 is adjusted to its position, the driving device is connected to one end of the traction roller 20 through a coupling.

[0032] In this embodiment, the combined plate 11 includes a fixed plate 111 fixed to the frame 10 and a movable plate 1 112 and a movable plate 2 113 located on both sides of the fixed plate 111, and the movable plate 1 112 and the movable plate 2 113 are slidably connected to the frame 10; the arc-shaped opening 114 is divided into two parts and is respectively provided on one side of the fixed plate 111 and the movable plate 1 112; the arc-shaped opening 2 115 is divided into two parts and is respectively provided on the other side of the fixed plate 111 and the movable plate 2 113; the movable plate 112 and the movable plate 2 113 can respectively pass through the two side walls of the frame 10 and move toward the outside of the frame 10.

[0033] Specifically, see Figure 3 , both ends of the frame 10 have rectangular openings, and guide slots 101 are provided on the frame 10 at the upper and lower positions of the rectangular openings. The guide slots 101 on both sides of the fixed plate 111 are used for the movement of movable plate 112 and movable plate 2 113 respectively. Move movable plate 112 and movable plate 2 113 along the guide slots 101. When movable plate 112 and movable plate 2 113 are close to each other, they can form a complete arc-shaped opening 114 and arc-shaped opening 2 115 on both sides of the fixed plate 111; when movable plate 112 and movable plate 2 113 are far away from each other, an opening can be formed between the fixed plate 111, and the traction long roller 20 can be installed and replaced from this opening, without the need to take all the rollers out of the annealing furnace, which saves a lot of installation time, reduces safety hazards, shortens production line downtime, and improves production efficiency.

[0034] See also Figure 4-Figure 6 The arc-shaped opening 114 and the arc-shaped opening 2 115 at one end of the frame 10 form an "eight"-shaped structure. The movable plate 112 and the movable plate 2 113 have a semi-arc-shaped opening 2 1124 that constitutes the arc-shaped opening 114 and the arc-shaped opening 2 115. The fixed plate 111 has two semi-arc-shaped openings 1112 on both sides. In this way, the two semi-arc-shaped openings 1112 respectively form the arc-shaped opening 114 and the arc-shaped opening 2 115 with the two semi-arc-shaped openings 2 1124. The curvature and radius of the arc-shaped opening 114 and the arc-shaped opening 2 115 can be designed. The traction long roller 20 can also be supported by the semi-arc-shaped opening 1112 on both sides of the fixed plate 111.

[0035] In one embodiment, the substrate glass forming pulling mechanism further includes a plurality of linear adjustment mechanisms 40. Two notches 102 are provided on either side of the frame 10. The movable plate 112 and the movable plate 2 113 are connected to the linear adjustment mechanisms 40 through the notches 102, allowing the movable plate 112 and the movable plate 2 113 to move away from or closer to the fixed plate 111. Specifically, four linear drive mechanisms are provided at the four notches 102, connected to the outer ends of the two movable plates 112 and the two movable plates 113. The linear drive mechanisms can control the movable plate 112 and the movable plate 2 113 to move away from or abut against the fixed plate 111.

[0036] Among them, the linear drive mechanism can be an electric cylinder, a pneumatic cylinder or an oil cylinder; of course, it can also be a low-cost component that can be manually controlled. Specifically, the linear adjustment mechanism 40 includes a fixed frame 41 connected to the frame 10 and a screw rod 42 connected to the fixed frame 41. One end of the screw rod 42 is connected to the movable plate 112 or the movable plate 2 113. A handle 43 is fixedly connected to the end of the screw rod 42 away from the movable plate 112 or the movable plate 2 113 for rotating the screw rod 42. The rotation of the screw rod 42 can drive the movable plate 112 or the movable plate 2 113 away from or close to the fixed plate 111.

[0037] In one embodiment, screw holes 1122 are provided on the movable plate 112 and the movable plate 2 113, and the movable plate 112 and the movable plate 2 113 are screwed to the screw rod 42 through the screw holes 1122, and the screw rod 42 is connected to the fixed axis rotation with the fixed frame 41. In this way, by rotating the screw rod 42, the movable plate 112 and the movable plate 2 113 are driven to move along the guide groove 101, and by changing the rotation direction of the screw rod 42, the movable plate 112 and the movable plate 2 113 can be made close to or away from the fixed plate 111.

[0038] In another embodiment, a screw hole 1122 is provided on the fixing frame 41, and the end of the screw rod 42 is fixedly connected to the movable plate. By rotating the screw rod 42, the screw rod 42 and the fixing frame 41 move relative to each other, driving the movable plate 112 and the movable plate 2 113 to move along the guide groove 101. By changing the rotation direction of the screw rod 42, the movable plate 112 and the movable plate 2 113 can be moved closer to or away from the fixed plate 111.

[0039] In this embodiment, groove 1111 is provided on both sides of the fixed plate 111, and groove 2 1121 is provided on the side of the movable plate 112 and the movable plate 2 113 facing the fixed plate 111. The groove 1111 and the groove 2 1121 are combined with the side surfaces of the fixed plate 111, the movable plate 112 and the movable plate 2 113 to form a stepped sealing structure, which has a sealing effect, blocks the flow of internal and external environmental fields, and is beneficial to improving the stability of the temperature field in the furnace body.

[0040] Under normal operating conditions, for a single traction roller 20, the connecting shafts 21 at both ends of the traction roller 20 are located within an arc-shaped track formed by two arc-shaped openings (arc-shaped opening 114 and arc-shaped opening 215) formed by a single-sided fixed door panel and movable door panels (movable door panel 1 and movable door panel 2). The installation process of the traction roller 20 and the steps and principles of hot online replacement are detailed as follows:

[0041] First, install the combined plates 11 at the two end faces of the frame 10, move the movable door panel outward, and reserve an installation position. Next, install the traction roller 20 on one side, and use the traction roller 20 installation tool to enter the furnace body from the installation position reserved for the movable panel. Then, place the connecting shaft 21 on the bottom of the semi-arc opening 1112 of the fixed plate 111. The semi-arc opening 1112 of the fixed door panel is different from the semi-arc opening 2 1124 of the movable door panel. The bottom of the semi-arc opening 1112 of the fixed plate 111 is a circular arc groove, which can be adapted to the shape of the connecting shaft 21. Then, rotate the screw rod 42 clockwise to drive the movable panel to move inward until it is completely consistent with the stepped sealing structure of the fixed plate 111. In this way, the traction roller 20 on one side is installed in the frame 10, and the installation process of the traction roller 20 on the other side is the same. Then, install the external rotating support arm 30 and its auxiliary structures, which will be described in detail later.

[0042] If the traction roller 20 needs to be replaced due to a fault in the hot working state, the removal process is the opposite of the installation process, as follows:

[0043] After removing the external support arm 30 and its associated structures, first rotate the screw 42 counterclockwise to move the movable plate outward and disengage it from the stepped sealing structure of the fixed plate 111. During this disengagement, the connecting shaft 21 is placed on the semi-arc-shaped opening 1112 of the fixed plate 111. Next, remove the single-sided traction roller 20. Use the original traction roller 20 installation tool to remove it from the reserved installation position of the movable plate and from the internal space of the furnace body. Then install the new traction roller 20 that was prepared in advance and repeat the installation process.

[0044] During the installation and removal process, the split design of the combined plate 11 of the present invention can provide stable support for the connecting shaft 21 of the traction roller 20, reducing safety hazards; the setting of the fixed plate 111 can reduce the fluctuation of the thermal environment in the furnace, reduce heat loss, and maintain the stability of the working hot zone to the maximum extent; the setting of the movable plate can greatly shorten the removal time and installation time of the end door panel, and effectively shorten the replacement time of the traction roller 20. In summary, through the present invention, the replacement process of the traction roller 20 in a hot state can be realized, saving time and labor, reducing safety hazards, effectively shortening the downtime of the production line, and improving production efficiency. At the same time, the movable plate forms an embedded structure through the guide slide 101 and the notch 102, which can improve the stability of the movable plate. At the same time, combined with the design of the support arm 30 and its auxiliary structure of the present invention, it can effectively reduce the shaking and deformation of the traction roller 20, improve the quality stability of the substrate glass, and lay a good equipment foundation.

[0045] In this embodiment, the support arm 30 includes a rotating plate 31, a crank 32 rigidly connected to one end of the rotating plate 31, and a bearing seat 34 detachably connected to the rotating plate 31. The crank 32 is provided with a threaded section for installing a counterweight 33; the rotating plate 31 is provided with a mounting hole 1 and a bearing seat 34, and the mounting hole 1 is provided with a rotating shaft, which is fixedly connected to the combination plate 11 1 or the combination plate 11 2. The bearing seat 34 is used to rotatably connect the end of the traction long roller 20.

[0046] Specifically, the rotating plate 31 is shaped like a fan-shaped flat plate, and two mounting holes are opened on its middle dividing line. Among them, a mounting hole away from the crank 32 is centrally installed with a bearing seat 34, a bearing is installed in the bearing seat 34, and the bearing and the connecting shaft 21 are centrally installed; in one case, the bearing seat 34 is fixed to the rotating plate 31 by screws, and the bearing and the connecting shaft 21 are interference fit, and the separation and assembly of the connecting shaft 21 of the traction long roller 20 and the support arm 30 are achieved by removing and installing the bearing seat 34; in another case, the bearing seat 34 is fixed to the rotating plate 31 by welding, and an external stop seat 37 is set on the bearing, so that the bearing and the connecting shaft 21 are assembled together, and the separation and assembly of the connecting shaft 21 of the traction long roller 20 and the support arm 30 are achieved by removing and installing the external stop seat 37; another mounting hole close to the crank 32, a fixed shaft is set in the mounting hole through the bearing and the internal stop seat, and the fixed shaft is welded or screwed or fixed by a pin to the positioning hole 1123 on the movable plate.

[0047] In one embodiment, an arc-shaped guard plate 35 is provided on the side of the support arm 30 close to the combined plate 11, which is used to cover the arc-shaped opening 114 and the arc-shaped opening 2 115 from the outside. The function of the arc-shaped guard plate 35 is mainly to provide a sealing function for the running track (arc-shaped opening 114 and arc-shaped opening 2 115) of the connecting shaft 21 of the traction long roller 20. Its appearance is arc-shaped and its structure is similar to that of an arc-shaped flat plate.

[0048] As mentioned above, after the traction roller 20 is installed and the movable plate is pushed to the defined position, the support arm 30 will be installed. First, install the fixed shaft in the positioning hole 1123 on the movable plate 112. Its main function is to provide effective support for the rotation of the support arm 30. After the fixed shaft is installed, install the inner block 36 and the bearing, and the fixed shaft and the bearing are matched.

[0049] At the same time, the connecting shaft 21 and the support arm 30 are initially positioned, the connecting shaft 21 passes through the reserved hole of the arc-shaped guard plate, enters the installation position of the bearing seat 34 on the rotating plate 31, and the bearing, the connecting shaft 21 and the bearing seat 34 are connected and installed. Then, the external stopper 37 is installed, and the installation is completed. If the traction long roller 20 is replaced and the support arm 30 is removed, the removal process is the opposite of the installation process and will not be repeated here.

[0050] The fan-shaped panel structure design adopted by the rotating plate 31 can maintain the stability of the support arm 30 during rotation. The rotating plate 31, the arc-shaped guard plate 35, the bearing mounting hole of the fixed shaft of the bearing seat 34 and the center line of the crank 32 coincide with each other, which can maintain the accuracy of rotation. The bearing seat 34 adopts a stepped design and is integrally arranged on the rotating plate 31, which can enhance the structural strength of the bearing rotation.

[0051] The support arm 30 is supported by the rotation of the fixed shaft, which can drive the movement of the traction roller 20 in the arc motion track. By adjusting the support arms 30 on both sides respectively, the closing state of the traction rollers 20 on both sides inside the furnace body can be changed; by adjusting the position of the counterweight block 33 on the crank 32 and increasing or decreasing the number of counterweights, the clamping force of the traction rollers 20 on both sides on the glass plate 50 can be changed.

[0052] The present invention also provides an annealing furnace, comprising several of the above-mentioned substrate glass forming traction mechanisms, wherein the multiple substrate glass forming traction mechanisms are sequentially arranged up and down to constitute the main structure of the annealing furnace, and heaters 12 are arranged on both sides of the frame 10 of each substrate glass forming traction mechanism. By adjusting the parameters of the heaters 12 at different height positions, a temperature gradient change is formed, so that the glass plate 50 can pass through different temperature fields, thereby achieving the purpose of controllable cooling speed. The annealing furnace effectively shortens the downtime of the production line and improves production efficiency.
