  • Patent number: 10670209
    Abstract: An interior rotating structure of a handicraft lantern comprises a lantern bracket, a transparent container, a sealed rotary mechanism, a mounting frame, a rear cover, and a motor body. The transparent container is fixed under the lantern bracket and the sealed rotary mechanism is inserted under the transparent container. The mounting frame is under the sealed rotary mechanism. A container sealing cover is installed in the sealed rotary mechanism, while a central impeller is mounted on the container sealing cover. The rotating structure includes a rotating gear and a shaft magnet on the motor shaft, so that the rotating gear drives a large inner ring gear to spin through multi-step transmission of a reduction gear set. The inner ring gear drives an impeller rotating bracket to rotate through the magnets, in such a way that the rotating bracket can agitate the liquid when the central impeller revolves at the same time.

  • Publication number: 20200048452
    Abstract: The invention is a polyoxymethylene film and a preparation method. The polyoxymethylene film comprises: 96 to 98 parts by weight of polyoxymethylene resin, 0.5 to 2 parts by weight of nucleating agent, 0.5 to 1 parts by weight of antioxidant, and 0.5 to 1 parts by weight of formaldehyde absorbent. In view of the high crystallinity and fast crystallization rate of polyoxymethylene, blown film process is used to directly blowing the molten mass extruded through a die of a screw extruder to form a blown film bubble. It is easy to form thin neck and easy to break when stretching, so the method is beneficial to form polyoxymethylene film, and has high processing efficiency, and is suitable for industrialization. Copolymerization unit —CH2—CH2—O— is introduced into the molecular chain of polyoxymethylene and its ratio is increased, thereby effectively reducing the crystallization rate of the materials and making it easier to form a film.
