[0002] The plastic extrusion flat film and flat wire auxiliary machine is a kind of equipment in the plastic extrusion production line. It is used to shape and process the plastic melt after extrusion to produce flat film sheets and flat wires. After the film is processed and formed, it needs to be used in conjunction with the film drying mechanism. The film drying mechanism can be used to dry the plastic sheet to remove moisture or volatile harmful substances on the surface of the film, thereby improving the product quality and production efficiency of the film.
[0003] At present, the diaphragm drying mechanism on the market generally places the diaphragm to be dried directly on the transmission belt when in use. The existing diaphragm drying mechanism cannot limit the placement position of the diaphragm according to the actual size of the diaphragm when drying the diaphragm. When the placement position of the diaphragm deviates, it cannot be transported to the bottom of the hot air blower for rapid drying. Therefore, we propose improvements to the diaphragm drying mechanism in the current plastic extrusion flat film flat wire auxiliary machine. Utility Model Content
