Abstract: The present disclosure belongs to the field of cellulose dissolution technology, particularly relates to a device for dissolving cellulose with high speed and solubility. The device comprises a baseplate and a dissolving canister arranged on surface of the baseplate, bottom surface of the dissolving canister is fixedly connected with a supporting column, and surface of the dissolving canister is installed with a liquid-discharge pipe. The device further comprises a stirring assembly arranged above the dissolving canister, and the stirring assembly comprises an L-shaped installing block arranged above the dissolving canister. Surface of the L-shaped installing block is fixedly connected with a connection block, and surface of the connection block is fixedly connected with a dispensing canister. Lower end of the dispensing canister is rotatably connected with a first synchronizing wheel, one side of the first synchronizing wheel away from the dispensing canister is fixedly connected with a rotation member.

Abstract: A palm-type mechanical gripper with variable-position and rotatable fingers and a dual-drive crank-slider parallel mechanism is provided with a crank-slider mechanism on the left side, which is an active driving structure and is driven by two stepping motors to respectively generate angular displacement of cranks and to change lengths of connecting rods, and a crank-slider mechanism on the right side, which is a driven mechanism and is driven at a constant speed by a pair of gears. The mechanical gripper is provided with three plate spring fingers, wherein two fingers are respectively installed on the connecting rods on left and right sides, and under the cooperative effect of the two stepping motors, the eccentricities of the cranks, the positions and angles of the two fingers respectively on the two connecting rods and the position of the other fixed finger can be changed through manual adjustment.

Abstract: Disclosed is an elastic corrugated pipe single-acting cylinder-driven mechanical gripper with a series-connection flexible hinge framework. The mechanical gripper consists of a palm and two flexible fingers or a palm and three flexible fingers. Each of the flexible fingers is identical in structure, and essentially consists of an elastic corrugated pipe single-acting cylinder (8) and a series-connection flexible hinge (4); configuration of the series-connection flexible hinge (4) is designed according to features of grasping objects; the mechanical gripper generates a grasping force by the elastic corrugated pipe single-acting cylinder (8).
