9. The method of operating a double-sided taping machine as claimed in claim 8, comprising the steps of:

A. unloading the guide roller frames of the first wrapping unit and the second wrapping unit, placing the whole wrapped strip for wrapping on a tension disc, and placing the standby whole wrapped strip on a strip coil storage rack; a guide roller frame of the first wrapping unit and the second wrapping unit is arranged;

B. a first layer of wrapping: the core material to be wrapped is led into a tension shaft of the first wrapping unit through a wire inlet guide wheel of the first wrapping unit, passes through the tension shaft and then enters a wrapping pipe, and a coated strip material on the tension disc is led by a steering guide wheel and a wrapping guide wheel and then enters the wrapping pipe through a wire threading groove and is wrapped on the core material; starting a tension shaft motor and a main shaft motor of the first wrapping unit, enabling the tension shaft motor to drive the tension shaft and the tension disc to rotate, and enabling the main shaft motor to drive the main shaft, the wrapping outer frame body and the wrapping pipe to rotate, so that a wrapping strip wraps the core material to obtain an intermediate wire;

C. the second layer is around the package: leading out an intermediate wire from a wire passing pipe of a first wrapping unit, sequentially leading the intermediate wire into a first steering guide wheel, a second steering guide wheel, a threading pipe and a third steering guide wheel, leading the intermediate wire led out by the third steering guide wheel into a tension shaft of a second wrapping unit, leading the intermediate wire into a wrapping pipe after passing through the tension shaft, leading a coated strip on a tension disc into the wrapping pipe through a threading groove after being guided by the steering guide wheel and a wrapping guide wheel, and wrapping the coated strip around the intermediate wire, starting a tension shaft motor and a main shaft motor of the second wrapping unit to drive the tension shaft and the wrapping pipe to rotate, driving the main shaft, a wrapping outer frame body and the tension disc to rotate by the main shaft motor, and realizing wrapping of the intermediate wire by the coated strip to obtain a cable;

D. the cable penetrates out of a wrapping pipe of the second wrapping unit and then enters the wire passing pipe, passes through the wire passing pipe and then enters an inner concave flat groove of the first traction guide wheel, is led out of the inner concave flat groove and then enters a first inner groove of the second traction guide wheel, is led out of the first inner groove and then turns back to enter the inner concave flat groove again, is led out of the inner concave flat groove and then enters a second inner groove of the second traction guide wheel, is led out of the second inner groove and then turns back to enter the inner concave flat groove again, is led out of the inner concave flat groove and then enters a third inner groove of the second traction guide wheel, is led out of the third inner groove and then enters the wire collecting roller, and the cable is arranged side by side on the inner concave flat groove so as to be wound on the first traction guide wheel and the second traction guide wheel for three times;

E. the cylinder is contracted, so that the front end of the gland is pulled down, and the belt enters the inward concave flat groove and is tightly attached to the cable; starting a traction motor to enable a first traction guide wheel to rotate, so that the cable is pulled;

F. after the wrapping belt materials on the tension discs of the first wrapping unit or the second wrapping unit are used up, the tension shaft motor, the main shaft motor and the traction motor are stopped, and the air cylinder contracts to enable the belt to compress the cable so as to stop wrapping; the guide roller frame is disassembled, the whole roll of the coating strip pre-stored on the corresponding strip coil storage rack is placed on the tension disc, the coating strip on the tension disc enters the strip pipe through the threading groove and is wound on the core material after being guided by the steering guide wheel and the strip guide wheel, the tension shaft motor, the main shaft motor and the traction motor are started, the belt is tightly attached to the cable after the cylinder extends, and the wrapping is continued.
