          Roving machine printing prototype

          Six axis fully servo cotton spinning roving frame JHF1718 sampling machine

          Six axis fully servo cotton spinning roving frame JHF1718 sampling machine

          JHF1718  seven-axis linkage full-servo cotton spinning computer roving frame, driven by seven servo motors, has simple structure, high degree of automation, equipped with power-off protection device, swift and sensitive reversal, overcomes  the  common  structural  reversal  of  yarn  blowing  and  other  drawbacks  and  realizes  roller  separate  control function, is the most advanced practical new wool spinning roving machine in China.
          The seven motors are used to drive each moving unit independently, and the synchronous servo control system with the combination of computer and servo technology makes the control precision of each system higher.
          Save heart, labor and labor: no need to replace twisted teeth and all the teeth drawing, reduce the workload of process and operator.
          It is more suitable for spinning, and is especially suitable for special spinning processes such as slub yan besides conventional varieties. The computer touch-screen is simple to operate and batch change, saving time and effort, and is convenient and quick.
          The range of total drawing multiple is enlarged and the disadvantage that the total drawing multiple of the former model is limited to the total drawing tooth is solved.
          Electrical control adopts bus control, which improves the stability of the system better.
          Seven servo synchronization control, the introduction of foreign advanced procedures to innovate and upgrade, greatly improve the multi- axis synchronization, improve the quality of spinning.
          Small size, small floor area, simple and convenient operation and adjustment, reducing the labor intensity of operators.
