[0001] This utility model relates to the field of glass substrate production equipment, and in particular to a self-blowing device for the television channel of a high-temperature kiln used in the production of TFT-LCD glass substrates. Background Technology
[0002] TFT-LCD glass substrates are thin glass sheets produced using the float glass process with extremely smooth surfaces. They are one of the essential raw materials for forming LCD panels. TFT-LCD panels typically consist of two glass substrates with a liquid crystal layer sandwiched between them. One substrate contains TFTs (Thin Film Transistors), and the other contains RGB color filters. The high-temperature furnace TV channel self-cleaning device used in TFT-LCD glass substrate production is a specially designed cleaning device for the high-temperature furnace TV channel and industrial TVs during the TFT-LCD glass substrate production process.
[0003] Existing self-cleaning devices for TV channels in high-temperature kilns used in TFT-LCD glass substrate production typically require manual entry into the kiln or disassembly of the equipment when cleaning TV channels and industrial TVs. This increases the risk of burns to personnel and downtime, resulting in a low level of automation. Furthermore, the cleaning of industrial TVs cannot be synchronized with kiln operation, leading to the risk of process fluctuations due to inspection interruptions, which hinders continuous production.
[0004] Therefore, it is necessary to propose a self-purging device for the TV channel of a high-temperature kiln used in the production of TFT-LCD glass substrates to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a self-blowing device for the TV channel of a high-temperature kiln in the production of TFT-LCD glass substrates. This device addresses the problem that cleaning the TV channel and industrial TVs requires manual entry into the kiln or disassembly of equipment, which increases the risk of burns and downtime, and results in a low degree of automation. Furthermore, the cleaning of industrial TVs cannot be synchronized with the operation of the kiln, leading to the risk of process fluctuations due to detection interruptions, which hinders continuous production.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-blowing device for a high-temperature kiln television channel in TFT-LCD glass substrate production, comprising a tube body, a cylindrical groove on one side of the tube body, and a sliding groove on the other side of the tube body, the sliding groove communicating with the cylindrical groove, an industrial television body being slidably disposed inside the sliding groove and the cylindrical groove, and four scrapers being uniformly fixedly connected to the inner wall of the cylindrical groove, the scrapers being in active contact with the outer periphery of the industrial television body;
[0007] The outer periphery of the tube is provided with an annular tube, and the inner wall of the annular tube is uniformly connected with four air outlet pipes in an annular shape. The air outlet pipes pass through the tube body and are connected to the cylindrical groove.
[0008] Preferably, the air outlet duct forms an angle with the side wall of the duct body.
[0009] Preferably, the scraper is inclined and has elasticity.
[0010] Preferably, an electric cylinder is provided on the side of the tube body near the slide groove, and a connecting rod is fixedly connected to the end of the piston rod of the electric cylinder. The end of the connecting rod is fixedly connected to the side wall of the industrial television body.
[0011] Preferably, the bottom of the annular tube is connected to a connecting pipe, a valve is provided on the connecting pipe, and a valve handle is installed on the top of the valve.
[0012] Preferably, a rack is fixedly connected to the side wall of the connecting rod, a rotating rod is rotatably arranged inside the slide groove, a gear is fixedly connected to the outer periphery of the rotating rod, the bottom end of the rotating rod passes through the tube and is fixedly connected to the valve handle, and the gear meshes with the rack.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. In this utility model, when the industrial TV body is pulled outward, the scraper removes the coke deposits on the industrial TV body, and the air blown out of the air duct blows the coke into the kiln, allowing the coke to decompose into gas at high temperature and be discharged from the flue, thus completing the cleaning of the industrial TV body. There is no need for manual entry into the kiln or disassembly of the equipment, realizing fully automated air blowing cleaning, reducing the risk of burns to personnel and downtime. At the same time, the cleaning of the industrial TV body is carried out simultaneously with the operation of the kiln, avoiding process fluctuations caused by detection interruptions, and providing a guarantee for continuous production.
[0015] 2. In this utility model, when the industrial television body is monitoring a high-temperature kiln, the annular pipe continuously supplies air to the cylindrical groove through the air outlet pipe to ensure that there is a weak airflow in the cylindrical groove, thereby reducing the temperature of the industrial television body and extending its service life. At the same time, it can reduce the precipitation and growth of coking material in the cylindrical groove to a certain extent.
[0016] 3. In this utility model, the air outlet pipe continuously blows air into the cylindrical groove, forming a dynamic air curtain barrier, which effectively blocks dust and high-temperature particles in the kiln from entering the interior of the cylindrical groove, reducing the risk of contamination inside the cylindrical groove and on the surface of the industrial television body. At the same time, the cleaning effect of the gas on the industrial television body can reduce the friction between the industrial television body and the inner wall of the chute, thereby improving the service life of the industrial television body.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, embodiments of this utility model, and should not be construed as limiting this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the description of this utility model, it should be understood that the terminology used is for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0025] This invention addresses the problems of necessitating manual entry into the kiln or disassembly of equipment for cleaning television channels and industrial televisions. This increases the risk of burns and downtime, and results in low automation. Furthermore, the cleaning of industrial televisions cannot be synchronized with kiln operation, leading to process fluctuations due to monitoring interruptions and hindering continuous production. The invention provides a solution such as… Figures 1-3 The device shown is a self-cleaning device for the TV channel of a high-temperature kiln used in the production of TFT-LCD glass substrates. It includes a tube body 1 with a cylindrical groove 11 on one side and a sliding groove 13 on the other side. The sliding groove 13 communicates with the cylindrical groove 11. An industrial TV body 2 is slidably disposed inside the sliding groove 13 and the cylindrical groove 11. Four scrapers 12 are evenly fixedly connected to the inner wall of the cylindrical groove 11, and the scrapers 12 are in active contact with the outer periphery of the industrial TV body 2. When using the device, the tube body 1 is installed at the top of the high-temperature kiln. The tube body 1 can be installed at an angle, with one side of the cylindrical groove 11 lower. When cleaning the industrial TV body 2 is required, the industrial TV body 2 is moved. As the industrial TV body 2 moves, the scrapers 12 scrape away the coking material on the outer periphery of the industrial TV body 2, ensuring that no coking material accumulates on the industrial TV body 2 and increasing its service life.
[0026] Furthermore, an annular pipe 3 is provided on the outer periphery of the pipe body 1. The inner wall of the annular pipe 3 is uniformly connected with four air outlet pipes 31 in an annular shape. The air outlet pipes 31 pass through the pipe body 1 and are connected to the cylindrical groove 11. When the industrial television body 2 is monitoring the high-temperature kiln, the annular pipe 3 continuously supplies air to the cylindrical groove 11 through the air outlet pipes 31 to ensure that there is a weak airflow in the cylindrical groove 11, which reduces the temperature of the industrial television body 2, extends its service life, and can reduce the precipitation and growth of coking material in the cylindrical groove 11 to a certain extent.
[0027] When the industrial television body 2 is pulled outward, the scraper 12 scrapes off the coke on the industrial television body 2, the air volume in the annular pipe 3 increases, and the annular pipe 3 blows air to the industrial television body 2 through the air outlet pipe 31. The airflow can blow the coke on the industrial television body 2 into the kiln, allowing the coke to decompose into gas at high temperature and be discharged out of the flue. When the industrial television body 2 moves into the slide 13, the gas blown out by the air outlet pipe 31 can also clean the lens of the industrial television body 2, avoiding damage to the industrial television body 2 caused by coking or coating.
[0028] The air outlet duct 31 continuously blows air into the cylindrical groove 11, creating a dynamic air curtain barrier that effectively blocks dust and high-temperature particles from entering the cylindrical groove 11, reducing the risk of contamination inside the cylindrical groove 11 and the surface of the industrial television body 2. At the same time, the cleaning effect of the gas on the industrial television body 2 reduces the friction between the industrial television body 2 and the inner wall of the slide 13, thus improving the service life of the industrial television body 2.
[0029] The components are designed to be integrated so that no manual entry into the kiln or disassembly of the equipment is required, enabling fully automated air-blowing cleaning. This reduces the risk of burns to personnel and downtime. The industrial TV body 2 is pulled out for cleaning in sync with the kiln operation, avoiding process fluctuations caused by inspection interruptions and ensuring continuous production.
[0030] In this invention, the air outlet pipe 31 forms a 45-degree angle with the side wall of the pipe body 1; the inclined setting of the air outlet pipe 31 can ensure that no matter how the gas is installed on the pipe body 1, the coke on the industrial television body 2 can be blown into the kiln.
[0031] It should be noted that the scraper 12 is inclined and has elasticity; the inclined setting of the scraper 12 can better scrape off the coke, and the elastic setting of the scraper 12 can flexibly fit the side wall surface of the industrial TV body 2, maintain close contact, and ensure that the coke is completely scraped off.
[0032] In this invention, an electric cylinder 4 is provided on the side of the tube body 1 near the slide groove 13. A connecting rod 41 is fixedly connected to the end of the piston rod of the electric cylinder 4. The end of the connecting rod 41 is fixedly connected to the side wall of the industrial television body 2. When the industrial television body 2 needs to be adjusted, the electric cylinder 4 is opened. The electric cylinder 4 drives the connecting rod 41 to move through the piston rod. The connecting rod 41 drives the industrial television body 2 to move, thereby completing the subsequent adjustment.
[0033] It should be noted that the electric cylinder 4 is installed on the outside of the high-temperature kiln via a mounting bracket, and the tube 1 passes through the opening of the high-temperature kiln, with the side near the slide 13 located on the outside of the high-temperature kiln.
[0034] Furthermore, a rack 42 is fixedly connected to the side wall of the connecting rod 41, and a rotating rod 44 is rotatably arranged inside the slide groove 13. A gear 43 is fixedly connected to the outer periphery of the rotating rod 44. The bottom end of the rotating rod 44 passes through the pipe body 1 and is fixedly connected to the valve handle 33. The gear 43 meshes with the rack 42. When the industrial television body 2 is being cleaned, the connecting rod 41 moves, causing the rack 42 on it to move. The rack 42 moves, causing the gear 43 to rotate. The gear 43 rotates, causing the rotating rod 44 to rotate. The rotating rod 44 rotates, causing the valve handle 33 to rotate. The valve handle 33 rotates, opening the valve, thereby increasing the airflow in the connecting pipe 32, which facilitates better cleaning of the industrial television body 2.
[0035] It should be noted that the bottom of the annular pipe 3 is connected to a connecting pipe 32, and a valve is installed on the connecting pipe 32. A valve handle 33 is installed on the top of the valve. When the industrial television body 2 monitors the high-temperature kiln, the valve is kept in a nearly fully closed state under normal conditions, with an opening of about 5%. When the industrial television body 2 is pulled out, the valve handle 33 rotates, opening the valve and increasing the airflow in the connecting pipe 32.
