Description

Technical Field

[0001] The utility model relates to a cooling air duct device for a calender, which is applied to a calender in glass production equipment. Background Art

[0002] The existing cooling air duct device for a calender

[0003] Due to the particularity of the calender (photovoltaic glass forming equipment), the forming of the finished glass is affected by many factors. One of the factors is the air under the plate, and the equipment operates in a high-temperature environment and needs air cooling. The existing cooling air ducts use soft branch pipes, such as canvas air ducts, which are fixed to the protruding air valves or connectors with tie straps. In this way, firstly, the position space of the air ducts is narrow, which is not conducive to the arrangement of the blowing pipes. The canvas material is easily damaged during the use process at the production site and is not easy to maintain. Secondly, the air ducts are greatly restricted and are easily bent, affecting the passage of the cooling air. At the same time, because the air knife (the air outlet device under the plate) of the calender needs to be adjusted up and down according to the use requirements at the production site, the corresponding blowing pipes are also adjusted up and down with the air knife. During the blowing process, if the canvas pipe is too long, it is easy to fold and bend, and the air output is extremely small, seriously affecting the production of glass. If the canvas pipe is too short, it cannot be adjusted up and down with the air knife. Thirdly, although the tie strap fixing method is convenient for replacement, it is easy to fall off. In addition, during the production process, it is not easy to detect situations such as falling off and damage. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a cooling air duct device for a calender with reasonable structural design, which can be flexibly set according to the position of the air knife, ensure the air volume, is not easy to leak air, is firmly fixed, is convenient to replace, and can timely detect the air leakage of the air duct.
