Description

Technical Field

[0001] This invention relates to the field of traction roller technology for glass substrate production, and specifically to a traction device for preventing loosening of asbestos cylinders in the production of hot ends of glass substrates. Background Technology

[0002] In the glass substrate production process, especially in the hot-end forming stage, molten glass flows out through a platinum channel and is then drawn and shaped by short traction rollers to ensure a uniform thickness of the glass substrate. Since the temperature of molten glass typically exceeds 1000°C, if the short traction rollers come into direct contact with the high-temperature molten glass, they will rapidly fail due to high-temperature oxidation or thermal fatigue. To protect the short traction rollers, existing technologies typically use an asbestos-based heat insulation sleeve on their outer side. The excellent high-temperature resistance of asbestos effectively isolates the high-temperature molten glass, thus ensuring the continuous operation of the traction process.

[0003] Currently, commonly used asbestos cartridges are mostly made by stacking multiple sets of annular asbestos sheets axially and pressing them against each other. This structure has a certain degree of flexibility, can adapt to the slight undulations on the surface of the glass substrate, and has a low manufacturing cost, so it is widely used in industrial practice. However, this type of asbestos cartridge has the following problems during use: Under the combined load of high temperature, high pressure, and continuous friction, the pressure between the asbestos sheets gradually decreases with the extension of the service time, causing relative slippage, increased gaps, and even local detachment of the asbestos sheets. On the one hand, this reduces the overall structural stability of the asbestos cartridge, making it impossible to maintain a uniform circumferential support force, which in turn causes uneven distribution of the traction force of the traction roller on the glass substrate, resulting in increased thickness deviation of the glass substrate and quality defects such as scratches or indentations on the surface; on the other hand, loose or detached asbestos sheets not only shorten the service life of the asbestos cartridge, but also increase the frequency of equipment downtime for replacement and production maintenance costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an anti-loosening asbestos cylinder traction device for the production of hot ends of glass substrates, which solves the problems mentioned in the background art.

[0010] Furthermore, the drive assembly includes a motor plate and a fixing block.

[0012] Furthermore, the heating component includes a mesh partition, which is fixedly connected inside the insulation box.

[0016] This invention provides an anti-loosening asbestos cylinder traction device for the production of hot ends of glass substrates. Compared with the prior art, it has the following advantages:

[0017] 1. By installing clamping components at both ends of the traction component surface: axial clamping force is applied from both ends of the asbestos ring sheet to tightly squeeze and fit the multiple arrays of asbestos ring sheets together, reducing the gap between the sheets and offsetting the loosening and displacement caused by long-term operation vibration and high-temperature thermal expansion and contraction. This structurally solves the core problem of asbestos cylinders becoming loose, falling off, and misaligned after long-term use.

[0018] 2. By heating the asbestos ring sheet, the high temperature on the glass substrate is avoided, which would cause the moisture inside the asbestos ring sheet to evaporate rapidly, preventing the asbestos sheet from cracking or loosening, thus increasing the service life of the asbestos ring sheet.

[0019] 3. The arc-shaped blocks on the surface of the traction roller and the arc-shaped groove in the middle of the asbestos ring reduce slippage between the traction roller and the asbestos ring when rotating, increasing the service life of the asbestos ring. At the same time, the conveying of glass substrates is more stable.

[0020] 4. The dehumidification and recirculation components can remove the water vapor generated during the heating of the asbestos ring sheet, allowing the heat to be reused and achieving energy saving.

[0021] 5. The design of the clamping components will facilitate the replacement of the asbestos rings by staff later on. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] To address the technical problems in the background art, the following is provided: a traction device for preventing loosening of asbestos cylinders in the production of hot ends of glass substrates:

[0044] Combination Figures 1-13 As shown, the present invention provides a traction device for preventing loosening of asbestos cylinders in the production of hot ends of glass substrates, comprising a base plate 100, a traction device 200 mounted on the top surface of the base plate 100, a first heating component 300 mounted on the top surface of the base plate 100 below the traction device 200, a second heating component 400 mounted on the top surface of the base plate 100 above the traction device 200, and a dehumidification reflux component 500 mounted on the top surface of the base plate 100 to one side of the traction device 200. The input end of the dehumidification reflux component 500 is connected to the second heating component 400, and the output end of the dehumidification reflux component 500 is connected to the first heating component 300. The traction device 200 includes a conveyor frame 201, which is fixedly connected to the top surface of the base plate 100. A drive component is mounted on one side of the conveyor frame 201. The top surface of the conveyor frame 201 is equipped with traction components at equal intervals, and the output end of the drive component is connected to the traction component. The traction component includes a first bearing seat 202 and a second bearing seat 203. The top surface of the conveyor frame 201 is symmetrically equipped with the first bearing seat 202 and the second bearing seat 203. A traction component is installed between the first bearing seat 202 and the second bearing seat 203. The surface of the traction component is arrayed with asbestos rings 204. The middle of the asbestos rings 204 is arrayed with arc-shaped slots 205. The two ends of the surface of the traction component are respectively equipped with clamping components. The traction component includes a traction roller 206. Arc-shaped blocks 207 are fixedly connected at equal intervals on the circumference of the traction roller 206. The two ends of the traction roller 206 are respectively fixedly connected with a first shaft 208 and a second shaft 209. The two ends of the traction roller 206 are arrayed with wire holes 210.

[0045] Through the above structure:

[0046] 1. The first heating component is arranged below the traction device and the second heating component is arranged above it: forming a symmetrical and encircling heating layout, which can achieve all-round and no dead angle heating and drying of the asbestos rings and asbestos cylinders on the traction device. Unlike the defects of uneven heating on one side, it can quickly remove the water vapor adsorbed inside the asbestos rings and the moisture contaminated during the production process, and prevent the asbestos rings from softening and loosening due to moisture from the source. At the same time, it can maintain the constant temperature conditions required for hot end production and adapt to the temperature environment requirements of glass substrate heat processing.

[0047] 2. Dehumidification and recirculation component: The input end is connected to the second heating component and the output end is connected to the first heating component. This constructs a closed-loop hot air circulation dehumidification pipeline system, which can extract and purify the humid and hot air carrying water vapor and odor generated during the drying operation of the upper and lower heating components in a timely manner. The purified dry hot air is then returned to the heating components for recycling. This not only dries and dehumidifies quickly and prevents water vapor residue from causing the asbestos cylinder to loosen, but also significantly reduces heating heat energy loss, achieving the goal of energy saving and consumption reduction in production.

[0048] 3. Asbestos rings are arrayed on the surface of the traction component, and an array of arc-shaped grooves are set in the middle of the asbestos rings: the asbestos rings directly contact the glass substrate for traction, relying on the high temperature resistance, heat insulation and wear resistance of asbestos material, which is suitable for high temperature working environment at the hot end; the arc-shaped grooves engage with the arc-shaped blocks of the traction roller for positioning, so as to achieve precise alignment and installation of the asbestos rings and the traction component, initially limiting the circumferential and radial displacement of the asbestos rings, avoiding individual rotation and displacement of a single asbestos ring, and building a solid foundation to prevent loosening;

[0049] 4. Clamping components are installed at both ends of the traction component surface: Axial clamping force is applied from both ends of the asbestos ring sheet to tightly squeeze and fit the multiple arrays of asbestos ring sheets together, reducing the gap between the sheets and offsetting the loosening and displacement caused by long-term operation vibration and high-temperature thermal expansion and contraction. This structurally solves the core problem of asbestos cylinders becoming loose, falling off, and misaligned after long-term use.

[0050] In this embodiment, the pressing component includes an annular elastic pad 211. The annular elastic pad 211 has a semi-sliding groove 228 arranged in a circular array in the middle. A spring 212 is arranged in a circular array on one side of the annular elastic pad 211. A buffer pad 213 is fixedly connected to one end of the spring 212. A small ring 214 is fixedly connected to one side of the buffer pad 213. A large ring 215 is fixedly connected to one side of the small ring 214.

[0051] The above structure, through the combination of elastic pads, springs, and double-layer buffer rings, achieves a flexible, constant-pressure, vibration-buffering, and uniformly compressed effect on the asbestos ring sheet. This not only continuously locks the asbestos ring sheet in place, preventing it from loosening or shifting, but also adapts to high-temperature deformation at the hot end and vibration conditions during equipment operation. It eliminates the problem of asbestos ring sheet breakage caused by rigid compression, and improves the adaptability and durability of the anti-loosening structure.

[0052] In this embodiment, the clamping component also includes a first semi-ring sleeve 216 and a second semi-ring sleeve 217. The two ends of the first semi-ring sleeve 216 are respectively fixedly connected to the second semi-ring sleeve 217 by bolts. The first semi-ring sleeve 216 and the second semi-ring sleeve 217 are respectively fixedly connected to a semi-clamping ring 218. One end of the first semi-ring sleeve 216 and the second semi-ring sleeve 217 are respectively provided with a through hole 219, and a long bolt 220 is installed in the through hole 219.

[0053] In the above structure, through holes are provided at the ends of the two half-rings, and long bolts are installed inside. These serve as the core locking components for adjusting the clamping force. By turning the long bolts, the clamping force of the half-rings can be finely adjusted, thereby controlling the spring compression and the clamping force of the annular elastic pad on the asbestos ring. The clamping strength can be flexibly adjusted according to the wear degree of the asbestos ring and the production conditions to meet the anti-loosening requirements of different production cycles.

[0054] In this embodiment, the annular elastic pad 211 is made of high-temperature resistant silicone rubber, the thickness of the annular elastic pad 211 is 3-5mm, and the surface of the annular elastic pad 211 is provided with anti-slip texture. The buffer pad is made of ceramic fiber material.

[0055] Through the above structure, by limiting the material and specifications of the core consumables of the clamping component, it is specifically adapted to the special working conditions of high temperature at the hot end of the glass substrate, ensuring that the clamping buffer structure does not fail, age, or slip under long-term high temperature environment. It strengthens the high temperature resistance, durability, and clamping stability of the anti-loosening structure from the source of the material, and avoids equipment failure and asbestos cylinder loosening and failure caused by the material's inability to withstand high temperature.

[0056] In this embodiment, the drive assembly includes a motor plate 221 and a fixing block 222. The motor plate 221 is fixedly connected to one side of the conveyor frame 201. A drive motor 223 is fixedly connected to the top surface of the motor plate 221. The output end of the drive motor 223 is rotatably connected to a drive rod 224 through a worm gear and worm wheel. The fixing block 222 is fixedly connected to one side of the conveyor frame 201. The drive rod 224 is rotatably connected inside the fixing block 222. The surface of the drive rod 224 is fixedly connected to a first pulley 225 at equal intervals. The surface of the first pulley 225 is rotatably connected to a second pulley 227 through a belt 226. The surface of the first shaft 208 is fixedly connected to the second pulley 227.

[0057] In the above structure: the drive assembly uses a drive motor to drive the drive shaft to rotate, and the drive shaft uses a first pulley, a belt and a second pulley to drive the traction roller to rotate, so as to realize the transportation of the glass substrate.

[0058] In this embodiment, the first heating component 300 includes a lifting hydraulic rod 301. The lifting hydraulic rod 301 is symmetrically and fixedly connected to the top surface of the base plate 100. The output end of the lifting hydraulic rod 301 is fixedly connected to a heat preservation box 302. Arc-shaped grooves 303 are evenly spaced on the top surface of the heat preservation box 302. A connecting pipe 304 is fixedly connected to one side of the heat preservation box 302. A heating component is installed inside the heat preservation box 302.

[0059] In the above structure: arc-shaped grooves are set at equal intervals on the top surface of the heat preservation box; the arc-shaped grooves are adapted to the shape of the shafts at both ends of the traction roller, and the shafts are locked when the heat preservation box is closed, so as to realize the complete sealing of the heating cavity, prevent the leakage of high temperature hot air and the entry of cold air from the outside, and ensure that the temperature in the heating cavity is uniform and stable, and the drying and dehumidification effect is uniform and consistent.

[0060] In this embodiment, the heating component includes a mesh partition 305. The mesh partition 305 is fixedly connected inside the heat preservation box 302. The inner cavity of the heat preservation box 302 is divided into a heating chamber 306 and an air inlet chamber 307 by the mesh partition 305. A heating wire 308 is installed on one side of the mesh partition 305 and inside the heating chamber 306. The connecting pipe 304 is connected to the air inlet chamber 307.

[0061] In the above structure, the heating component is separated into a heating chamber and an air inlet chamber by a mesh partition: this allows the incoming circulating hot air to be evenly distributed, avoiding airflow turbulence and uneven local heating.

[0062] In this embodiment, the second heating component 400 includes a bent rod 401, which is fixedly connected to the top surface of the base plate 100. A heating element is installed at the lower part of one end of the bent rod 401. The heating element adopts the same structure as the first heating component 300, and the heating element is symmetrically installed with the first heating component 300.

[0063] The above structure features symmetrical, identical heating components arranged on both sides to form a double-sided, balanced heating and drying system. This ensures that the asbestos ring sheet has a completely consistent level of dryness and moisture content, as well as a uniform heating temperature. This eliminates the problem of localized loosening caused by uneven drying or moisture absorption, and maximizes the effectiveness of the pretreatment to prevent loosening.

[0064] In this embodiment, the dehumidification recirculation assembly 500 includes a dehumidification box 501. The dehumidification box 501 is fixedly connected to the top surface of the base plate 100. Activated carbon 502 and resin plate 503 are fixedly connected to the upper part of the inner cavity of the dehumidification box 501, respectively. A motor frame 504 is fixedly connected to the lower part of the inner cavity of the dehumidification box 501. A fan motor 505 is fixedly connected to the top surface of the motor frame 504. A suction fan blade 506 is fixedly connected to the output end of the fan motor 505.

[0065] Through the above structure:

[0066] 1. The upper part of the dehumidification box is equipped with a double-layer purification and adsorption structure of activated carbon and resin plate: activated carbon adsorbs small molecule water vapor and production odor impurities in hot air, and resin plate deeply adsorbs residual moisture. The double purification superposition realizes deep drying and dehydration of hot air, ensuring that there is no residual water vapor in the return hot air and that the circulating heating does not cause moisture to return.

[0067] 2. The lower part of the dehumidification box is equipped with a motor frame, a fan motor, and a suction fan blade: providing power for hot air circulation and extraction, forcibly driving the hot and humid air from the heating element into the dehumidification box for purification, and then returning to the heating element, realizing active hot air circulation, accelerating the dehumidification and drying speed, and improving recycling efficiency.

[0068] In this embodiment, the dehumidification recirculation assembly 500 includes an air inlet pipe 507 and an air outlet pipe 508. The air inlet pipe 507 is fixedly connected to the top surface of the dehumidification box 501 and is connected to the second heating assembly 400. The air outlet pipe 508 is fixedly connected to the bottom surface of the dehumidification box 501 and is connected to the first heating assembly 300 at one end.

[0069] Through the above structure, the air inlet pipe and the air outlet pipe connect the upper and lower heating components and the dehumidification box, thus constructing a complete hot air circulation dehumidification and energy-saving system. This system achieves directional water vapor treatment and hot air circulation reuse, while also meeting the needs of asbestos cylinder dehumidification to prevent loosening and the production goal of energy saving and consumption reduction.

[0070] Working principle and usage process of this invention:

[0071] In use:

[0072] The first step is to install the asbestos ring 204 and assemble the traction device 200: First, install the asbestos ring 204: During installation, the worker aligns the arc-shaped groove 205 in the middle of the asbestos ring 204 with the arc-shaped block 207 on the surface of the traction roller 206. After alignment, the asbestos ring 204 is fitted onto the surface of the traction roller 206. The installation of the asbestos ring 204 is stopped once the surface of the traction roller 206 is fully fitted with the asbestos ring 204.

[0073] Next, install the clamping components: During installation, first align the semi-sliding groove 228 in the middle of the annular elastic pad 211 with the surface of the traction roller 206, and insert the annular elastic pad 211 into the surface of the traction roller 206; after insertion, assemble the annular elastic pad 211, spring 212, buffer pad 213, small ring 214 and large ring 215 in sequence. The annular elastic pad 211, spring 212, buffer pad 213, small ring 214 and large ring 215 are an integrated fixed structure.

[0074] After the above components are installed, the first half-ring sleeve 216 and the second half-ring sleeve 217 are assembled. During installation, the worker aligns the half-ring 218 with the small ring 214 and inserts it. The two sides of the half-ring 218 contact the sides of the buffer pad 213 and the large ring 215, respectively. After the two sets of half-rings 218 are in place, the sides of the first half-ring sleeve 216 and the second half-ring sleeve 217 fit together. After fitting together, the worker uses bolts to lock and fix them. Then, the long bolt 220 is screwed on. During the rotation of the long bolt 220, the first half-ring sleeve 216 and the second half-ring sleeve 217 are pressed together, so that the first half-ring sleeve 216 and the second half-ring sleeve 217 are firmly connected to the traction roller 206. When the first half-ring 216 and the second half-ring 217 are subjected to force, they simultaneously drive the buffer pad 213, the small ring 214 and the large ring 215 to move as a whole. When the buffer pad 213 moves, it compresses the spring 212. The spring 212 is forced to compress the annular elastic pad 211. The annular elastic pad 211 is forced to compress the asbestos ring sheet 204, so that multiple sets of asbestos ring sheets 204 are pressed together and the fit gap is reduced. This prevents the asbestos ring sheets 204 from shifting, loosening and other problems after long-term use.

[0075] After the clamping components are installed, the workers assemble the first bearing seat 202 on the first shaft 208, and then install the second bearing seat 203 on the surface of the second shaft 209. After the bearing seats are installed, the second pulley 227 is installed on the first shaft 208, and then the first pulley 225 and the second pulley 227 are connected by a belt 226 to complete the initial assembly of the traction device.

[0076] The second step involves heating the assembled asbestos ring sheet 204: The lifting hydraulic rods 301 of the first and second heating components are activated. As the lifting hydraulic rods 301 operate, they drive the two sets of insulation boxes 302 to move towards each other. During this movement, the arc-shaped grooves 303 on the inner side of the insulation boxes 302 engage with the surfaces of the first shaft 208 and the second shaft 209. After the two sets of insulation boxes 302 are fully fitted together, they form a completely enclosed box. At this time, the heating wire 308 starts working, heating and drying the asbestos ring sheet 204. The drying temperature is controlled at 200-250℃, and the drying time is 2-3 hours, thereby removing moisture from the inside of the asbestos ring sheet 204. During the drying process, the fan motor 505 drives the suction fan blades 506 to rotate. The rotation of the suction fan blades 506 guides the air inside the dehumidification box 501 into the exhaust pipe 508, and finally delivers it to the air inlet chamber 307. After the airflow enters the air inlet cavity 307, it is blocked by the mesh partition 305 and evenly dispersed inside the air inlet cavity 307. Then, the airflow penetrates the mesh partition 305 and enters the heating cavity 306, continuing to flow upward and into the second heating component 400. Simultaneously, the airflow carries water vapor and is discharged from the second heating component 400. The airflow carrying water vapor enters the upper part of the dehumidification box 501, and successively penetrates the activated carbon 502 and the resin plate 503. The activated carbon 502 and the resin plate 503 adsorb water vapor and odor gases in the air. The purified hot air flows back into the first heating component 300, realizing the recycling of hot air and effectively reducing energy consumption.

[0077] The third step involves the traction of the glass substrate: After the heating process is completed, the lifting hydraulic rod 301 moves the insulation box 302 away from the asbestos ring 204. After separation, the drive motor 223 is started, which drives the drive rod 224 to rotate. The rotation of the drive rod 224 synchronously drives the first pulley 225 to rotate, which in turn drives the second pulley 227, ultimately driving the traction roller 206 to rotate synchronously with the asbestos ring 204. After the glass substrate is output from the platinum channel, the conveying speed of the traction device is controlled at 0.5-2 m / min, stably achieving continuous traction and conveying of the glass substrate.
