According to the dielectric elastomer flexible foot provided by the invention, through an upper-side dielectric elastomer driver (extendable) and a lower-side silica gel elastomer sole (extendable and deformable), when the dielectric elastomer driver is electrified, the dielectric elastomer flexible foot is bent towards the lower side; the concave-convex structure on the surface of the soft foot bottom ensures the friction force between the flexible foot and the environment. According to the starfish-imitating soft robot, a center radiation symmetrical structure is adopted, the starfish-imitating soft robot conforms to the movement mode of starfishes, and compared with other robot structures, the starfish-imitating soft robot can adapt to different terrains of the seabed; and the dielectric elastomer is flexible enough and is electrically deformed, so that compared with a thermally-induced deformation material, the energy efficiency is higher.

Star wheel bobbin rotary disc
ActiveCN102849495ACompact structureThe connection method is reasonableWebs handlingBobbinMolding machine
The invention provides a star wheel bobbin rotary disc which is used for placing bobbins and providing paper for a molding machine. The star wheel bobbin rotary disc is composed of a rotary disc body, a gear transmission system, two bobbin supports and the like. The rotary disc body is composed of a detachable sealing metal casing, and the gear transmission system is composed of a motor, a central shaft, a plurality of groups of gears meshed or in linkage connection with one another, two transmission shafts and the like. Each bobbin support is formed by an eccentric supporting plate, a bobbin shaft, a bearing, a bobbin base, a braking assembly, a cover cap, an adjusting nut and the like. The rotary disc body can rotate around the central shaft, the motor can drive the central shaft, the gear and the two transmission shafts to rotate. Inner shaft holes of the eccentric supporting plates are sleeved on the transmission shafts, bearing inner rings are sleeved on the bobbin shafts, and bearing outer rings are connected with the bobbin bases in matching mode. The bobbins are arranged between the bobbin bases and the cover caps. The braking assemblies are used for controlling rotating or braking of the bobbin bases and the like, and the adjusting nuts are used for adjusting axial positions of the bobbins. The star wheel bobbin rotary disc is compact in components, small in rotary space, capable of replacing the bobbins automatically, good in splicing stability, and high in efficiency.

Automatic water draining device and fuel filter using automatic water draining device and using method thereof
The invention discloses an automatic water draining device. The automatic water draining device comprises a valve body, an inner cylinder is arranged in the valve body and vertically arranged, the outer wall of the inner cylinder is covered with an annular coil rack, and a coil used for producing a magnetic field is wound on the coil rack; a sewer pipe is arranged on the upper portion of the valvebody, downwards stretches into the inner cylinder and communicates with the inner cylinder; and a spring jacking sealing structure and a magnetic adsorption water draining structure are arranged in the valve body. The invention further discloses a fuel filter which adopts the automatic water draining device and has an automatic water draining function and a using method thereof. According to theautomatic water draining device, the fuel filter using the automatic water draining device and the using method, water can be automatically drained in time, the condition that a water collecting cavity is filled with water is avoided, the service life of a filter element is prolonged, the condition that an engine is damaged due to the fact that fuel oil contains water is prevented, the using costof the fuel filter with the automatic water draining function and a motor vehicle is reduced, and the maintenance operation frequency is decreased.
