Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of POF cross-linked film preparation washing post-processing, and specifically provides a POF cross-linked film preparation washing post-processing device. BACKGROUND

[0002] POF cross-linked film is prepared by using linear density polyethylene as an intermediate layer, copolymerized polypropylene as inner and outer layers, plasticizing extrusion through three extruders, and then forming through a die head and bubble inflation processing. When the POF cross-linked film is washed and post-processed, it needs to be cut according to the appropriate length. In order to improve the sealing performance and leak-proof performance of the POF cross-linked film, the cut of the POF cross-linked film post-processing needs to be hot melt treated, mainly for sealing. The hot melt treatment of the cut can make the film material form a bonding layer at the cut through hot melt treatment, so that the film material can be firmly bonded together during sealing, avoiding air leakage and leakage problems after sealing. The hot melt treatment of the cut can also improve the appearance of the POF cross-linked film. Therefore, the hot melt treatment of the cut of the POF cross-linked film is a very important link in the post-processing of the POF cross-linked film, which can effectively improve the sealing performance and appearance of the POF cross-linked film.

[0003] During the washing post-processing of the POF cross-linked film, the following problems exist: during the washing post-processing of the POF cross-linked film, the traditional method is to cut first and then dissolve or to melt first and then cut. This method is prone to inaccurate alignment of subsequent work, which may affect the processing quality. In addition, this method requires certain operation steps, which may reduce work efficiency. Whether cutting first and then dissolving or melting first and then cutting, the direct cutting or melting method is prone to cause wrinkles in the POF cross-linked film, which may affect the subsequent processing effect.

[0004] Therefore, in order to avoid affecting the processing quality and cutting effect of the POF cross-linked film, the present application provides a POF cross-linked film preparation washing post-processing device. SUMMARY
