HY490 Roving Frame

Economic Solutions

Economic Solutions: The maximum mechanical speed is 1600rpm; HY490 is developed under our long experience in the field of spinning, it can produce high quality yarn with competitive investment costs. It provides more choices for customer to select roving frame from HONGYUAN Company. It can transform the old model into computer-control system with lowest investment. High-level electromechanical integration: Eliminate conventional cone drum mechanism,reversing and building mechanism,and adopt two motors to drive separately Apply modern drive and control technology to form the high-accuracy follow control system that realizes synchronous control between motors, and spin with optimum roving tension. Superior quality roving: 4 - roller with double short aprons is adoptedSeparating the collection zone (between the first and the second roller) from the main draft zone (between the second and the third roller) can shorten the non-twisting zone,which is in favor of evenness of twist and high quality of roving In the whole course of roving, the control system of real-time measure   and feedback, which is composed of several high-accuracy rotary encoders and computer, controls the roving tension strictly according to the mathematics model. The unique control system that can restrain yarn faults effectively at the start and the stop of the machine,guarantees the stability of roving quality. Applying the patent technology of power cut-off avoids the breakages or yarn faults happening on whole machine when accident disconnection fault caused on outer electricity network. High efficiency: Adopt fully-enclosed high-speed flyer, fully-enclosed oil-bath gearbox, which has the feature of low noise at high speed. Controlled by microcomputer, the rotational speed of flyer can be changed automatically in the case big package, so can reduce the breakage of roving and improve production efficiency. Achieve the stopping of machine with full bobbin at fixed position and fixed direction, precisely control the bobbin length. Achieve the machine stopping with roving breakage at fixed position and fixed direction, which is easy for operation. Convenient maintenance: Perfect electric control system has features of reasonable arrangement and structure, strong anti- interference ability, high reliability, and convenient maintenance. The structure of driving is simple,saving time of maintenance.

It could communicate with all kinds of PC through network at high speed,so as to achieve the network production management and remote malfunction analysis.
