Abrégé

Disclosed is a bag mouth independent clamping device, comprising an overall frame (1), wherein an outer clamp is fixedly connected outside the overall frame (1); an inner clamp is slidably connected inside the overall frame (1); the outer clamp comprises an upper outer clamp and a lower outer clamp arranged oppositely, the upper outer clamp and the lower outer clamp respectively comprise an outer driving member (2) and an outer clamping member (3), and the outer driving member (2) and the outer clamping member (3) are connected; the inner clamp comprises an inner clamp frame, the inner clamp frame is connected to a horizontal driving member (10), and the horizontal driving member (10) drives the inner clamp frame to horizontally slide in the overall frame (1); and an upper inner clamp and a lower inner clamp are oppositely arranged inside the inner clamp frame, the upper inner clamp and the lower inner clamp respectively comprise an inner driving member (15) and an inner clamping member (16), and the inner driving member (15) and the inner clamping member (16) are connected. Each clamping member of the device has an independent driving member for driving, and the reciprocating motion of the inner clamp relative to the outer clamp is realized through the horizontal driving member, thereby satisfying the functional requirement of cheese yarn being compactly and controllably arranged in a bag.

Abrégé

Disclosed is a combined roving frame, comprising a power output mechanism (1) and two sets of spinning mechanisms (2). Two ends of the power output mechanism (1) are integrally connected to the spinning mechanisms (2) respectively, the power output mechanism (1) is provided with two sets of power output units, and one set of spinning mechanisms (2) is adapted to one set of power output units. The power output mechanism (1) further comprises a supporting frame (3), wherein two ends of the supporting frame (3) are integrally connected to the spinning mechanisms (2) respectively, and the two sets of power output units are symmetrically placed on the supporting frame (3). The combined roving frame is provided with the two sets of spinning mechanisms (2), wherein each set of spinning mechanisms (2) is adapted to one set of power output units, independently providing power to one of the sets of spinning mechanisms (2) that do not affect each other, rough yarns of different types can be separately spun by the two sets of spinning mechanisms (2), and rough yarns of the same type can also be spun at the same time. The number of spindles of the two sets of spinning mechanisms (2) is two times that of the original roving frame, the single-machine yield and the production efficiency of the roving frame can be greatly increased, and when spinning rough yarns of different types, the power output unit independently drives one set of spinning mechanisms (2), thereby providing good stability.
