Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of secondary heat setting of diaphragms, in particular to secondary heat setting equipment for polyethylene diaphragms. Background Art
[0002] Polyethylene diaphragms need to undergo secondary heat setting during the production process, and the diaphragms need to be processed during the secondary heat setting.
[0003] According to observations based on prior art, when the film is subjected to secondary heating and shaping, attention must be paid to whether there are wrinkles on the surface of the processed film, and then stretching and shaping are performed. However, when the wrinkles are processed, hot air is blown on the film and then the heat is used to make the film soft, and then the wrinkled parts of the film are unfolded. However, when the blow pipe works for a long time, the internal heat accumulation will cause the temperature to rise, and the temperature rise will cause the heat of the blown air to increase. If the heat is too high, the film will be melted, thereby affecting the quality of production and processing, and thus affecting the quality of the finished product. Utility Model Content
