Abstract

The invention discloses a roving frame transmission device. A lifting transmission shaft horizontally penetrates through a headstock and a tailstock machine frame of a roving frame and is driven to perform forward and reverse rotation by a transmission shaft driving device installed between two adjacent wallboards, a gear is installed on the lifting transmission shaft extending out of one side of a wall, a keel is installed at the bottom end of a keel supporting foot rack meshed with the gear, the bottom of the keel is connected with one end of a keel lever, the other end of the keel lever is provided with a supporting point, and a balance mechanism enabling the keel lever to be balanced is lifted on the keel lever. The roving frame transmission device can provide invariable balance force large in weight to act on the lever, stable balancing moment is generated, on one hand, torque borne by the lifting transmission shaft in the keel lifting process can be shared, on the other hand, balance and stability in the lifting process can be guaranteed, keel shaking caused by increase of spindles on the keel is avoided, the roving frame keel lifting transmission shaft is good in torsional rigidity, the torque borne by the lifting transmission shaft is small, and rough yarn is formed and packaged well.

Description

technical field [0001] The invention relates to the field of cotton textile machinery and equipment, in particular to a transmission device for a roving frame. Background technique [0002] In the cotton spinning spindle roving frame, the lifting transmission of the lower dragon bar is not only responsible for the transmission of the bobbin, but also ensures that the winding angular velocity decreases with the increase of the bobbin diameter, so that it can generate the winding speed and meet the winding forming conditions. Mainly in order to ensure the up and down movement of the lower rib, the change of the lifting stroke is completed through the control of the motor and PLC: 1) The lifting stroke decreases with the increase of the diameter of the bobbin, shortening the lifting stroke of the dragon tendon, that is, the roving is After each layer is wound on the bobbin, the forming angle period is shortened by Δt, so that the upper and lower forming angles of the roving pac...
