The invention relates to a cloth roller transmission device of a friction-free cloth rolling
machine, which comprises a base, a transmission case and a reversing frame with two sides being correspondingly and respectively provided with a side case. A cloth pulling shaft set is arranged at the top of the two side cases, and a cloth roller is arranged at the front of the two side cases. The cloth roller is connected with the cloth pulling shaft set in a driving way through a transmission mechanism which is installed in one side case. The transmission mechanism comprises a permanent
magnet tension controller which is provided with a power input shaft and a
power output shaft, a first transmission
assembly which is arranged between the power input shaft of the permanent
magnet tension controller and the cloth pulling shaft set, and a second transmission
assembly which is arranged between the
power output shaft of the permanent
magnet tension controller and the cloth roller. By using the permanent magnet tension controller which transfers
constant torque force by using a
magnetic field as a medium, the cloth roller transmission device of the friction-free cloth rolling
machine has the advantages that the friction-free transmission is realized, the output torque force is convenient to adjust, the service life of the transmission mechanism is greatly prolonged, the magnitudes of internal tension and external tension of rolled cloth are consistent, and the quality of the cloth is improved.
