  • Publication number: 20180207981
    Abstract: The present invention relates to a roller component having a suspension and a roller mounting rack. One end of the roller mounting rack has a cavity and is disposed inside the suspension in a sleeved manner. An articulated shaft is located inside the cavity. Two ends of the articulated shaft respectively pass through corresponding inner wall of the cavity and are connected to the suspension to make the roller mounting rack connected to the suspension in an articulated manner; a spring in a pre-compressed state is embedded in the cavity, and sleeved on the articulated shaft; the other end of the roller mounting rack is intended to mount a roller. The present invention plays a buffering and cushioning role to the roller and can raise the contact area and adhesive force of the roller with the ground surface and make the roller cling to the ground and move steadily.

  • Patent number: 9725901
    Abstract: A composite board is formed from binding a cover layer to a base layer, wherein the base layer has a composition comprising one or more of the following ingredients: magnesium oxide, recycled magnesium oxide, fibrous chips, wood chips, bamboo chips, chemical additive and water. A method of manufacturing the composite board includes providing the base layer, which includes preparing a semi-arid mixture of the above ingredients, and pouring the mixture through a funnel onto a conveyor belt. The conveyor belt passes the mixture through a series of rollers to remove excess liquid. The layer is cut into panels, which are heat before being sprayed with dried magnesium oxide. A binding agent is applied to one side of the base layer. The cover layer has a bottom surface which is then aligned and bonded to one side of the base layer.

  • Publication number: 20160158963
    Abstract: A construction panel is formed from a composition comprising one or more of the following ingredients: magnesium oxide, recycled magnesium oxide, fibrous chips, wood chips, bamboo chips, chemical additive and water. A method of manufacturing the construction panel is also disclosed to include mixing magnesium oxide, recycled magnesium oxide, fibrous chips and chemical additive in an aqueous solution to form a semi-arid mixture, and pouring the mixture through a funnel onto a conveyor belt. The conveyor belt passes the mixture through a series of rollers to spread the mixture out evenly in a layer and remove excess liquid. The layer is then cut into panels, which are heat by solar energy before being passing through a spray jet of dried magnesium oxide, and stacked.
