Technical Field
[0001] This utility model relates to the field of pipeline sealing technology, specifically to an automatic heating and sealing device for polyethylene tubular film. Background Technology
[0002] Currently, polyethylene (PE) tubular film is used for packaging plastic pipes in the automatic packaging process of the production line. When sealing, a cylinder is needed to pre-lengthen and fold the tubular film. The tubular film packaging leaves a long length at both ends when sealing, which results in the waste of polyethylene (PE) tubular film.
[0003] Furthermore, traditional methods require the use of tape for sealing, and tape seals are often weak and prone to coming off. On-site operation is cumbersome and packaging costs are high. Therefore, there is an urgent need to design an automatic heating and sealing device for polyethylene tubular film to solve these problems. Utility Model Content
