Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coiling devices, and particularly relates to a PET film coiling device for preventing loosening. Background Technique
[0002] PET film is a packaging film with relatively comprehensive properties. It has good transparency, luster, good airtightness and fragrance retention, medium moisture resistance, and its moisture permeability decreases at low temperatures. The mechanical properties of PET film are excellent, and its toughness is the best among all thermoplastics. Its tensile strength and impact strength are much higher than those of general films, and it has good stiffness, dimensional stability, and is suitable for secondary processing such as printing and paper bags. PET film also has excellent heat resistance, cold resistance, good chemical resistance and oil resistance, but it is not resistant to strong alkalis, is easy to generate static electricity, and there is no appropriate antistatic method yet. Therefore, attention should be paid when packaging powdery items.
[0003] Chinese Patent Authorization Publication No. CN215797337U discloses a PET film coiling device, including a winding roller. Fixed disks are fixedly installed at both the front and rear ends of the winding roller. A resistance strip is fixedly installed inside the fixed disk. A contact is slidably connected to the front end of the resistance strip. A support rod is fixedly installed at one end of the fixed disk away from the winding roller. A rotating shaft is arranged on the left side of the winding roller. A bushing is rotatably connected to the surface of the rotating shaft. A fixed rod is fixedly installed on the surface of the bushing. A limiting rod is fixedly installed at one end of the fixed rod away from the bushing. In this PET film coiling device, after the winding roller stops rotating, the limiting rod rotates and fixes the winding roller to prevent the winding roller from continuing to rotate due to inertia after the coiling is completed, resulting in film loosening, and controlling the fixing force of the limiting rod on the winding roller to prevent the film from being damaged due to excessive fixing force or the winding roller not being fixed stably due to too small fixing force.
