Description

Technical Field

[0001] The invention belongs to the technical field of replacement of leaky plates in the glass fiber industry, and in particular relates to automated equipment and a replacement method for leaky plates in the glass fiber industry. Background Art

[0002] In the glass fiber industry, the leak plate is one of the important production equipment. The leak plate is a narrow and long container with many holes. The molten glass becomes thinner after passing through the leak plate and the holes of the leak plate. The leak plate is supported by the leak plate frame and the casting material. The leak plate frame is supported by bolts and drag feet to install the leak plate under the passage. Due to the extremely high temperature and strong corrosiveness of the working environment of the leak plate, the temperature of the molten glass liquid is as high as 1200℃ or more. The leak plate will inevitably be damaged and deformed during use and need to be replaced. The net weight of the leak plate is about 20-35kg. With the continuous upgrading and improvement of the current process, the weight of the leak plate is also increasing. There are fixed bellows cooling blowing devices and partitions before and after the leak plate at the bottom of the passage, and there is an oiling system on the lower side. The horizontal space distance between the upper front and rear is less than 750mm, and the lower spacing is less than 450mm. The removal of the old leak plate and the replacement of the new one require two people to work together at the same time. The minimum height of the leak plate is about 0.9 meters and the maximum height is about 2.15 meters. The replacement process is usually done manually, which requires a lot of manpower and time, and the operator's working environment is poor and safety cannot be guaranteed. With the expansion of production scale and the improvement of automation, the traditional manual replacement method can no longer meet the needs of production.

[0003] The prior patent "A special device for replacing leak plates" (application number: CN202310454299.7) provides a special device for replacing leak plates. It limits the position through the top fixed plate, and uses the rocker arm mechanism on the C-shaped guide rail bracket to control the wire rope to drive the main swing arm to rise and fall to achieve height adjustment. The horizontal position of the leak plate fixing plate is changed by the main swing arm and the secondary cantilever. However, this method requires changing the position of the top fixed plate multiple times and cannot achieve precise adjustment. Summary of the invention

After completing the lifting action, click the screen to record the current position as 2, and so on to record the position, a total of 6 positions are recorded.

[0062] Use the wired handle to control the lifting and translation route of the operating platform 7. Each time the moving direction is changed, click on the visual operation screen 10 to store the position. After the screw mechanism 4 in the groove column 3 is lifted to a certain height, the operating platform 7 moves along the optical axis guide rail 6. After moving to the bottom of the leak plate, use the handle to lift the operating platform 7 to the bottom of the leak plate. Click the screen to store this position as position 5 to complete the setting of the installation route. After reaching this position, the PLC setting program is memorized 6 times in total.
