At this time, the inner piston 33 pushes the oil in the outer curved tube 30 to move, so that the piston head 31 on one side of the nylon roller 27 is lifted up and the piston head 31 on one side of the metal embossing roller 28 falls down, and the piston head 31 lifts the double roller frame 24, so that the double roller frame 24 rotates and the nylon roller 27 is lifted up.

After the fabric enters the spray range of the atomizing nozzle 15, the electrostatic generator 16 and the atomizing nozzle 15 are started. At this time, the negatively charged coating particles are evenly dropped on the fabric surface through the atomizing nozzle 15. At this time, the single coating process in the duvet fabric production process is completed, and the fabric is continuously conveyed between the adjustable damping upper roller 3 and the nylon roller 27; the damping of the adjustable damping upper roller 3 is adjusted according to different fabric thicknesses, number of layers and process requirements, thereby changing the adjustable damping upper roller 3. The downward pressure on the cloth is exerted by changing the current flowing through the electromagnetic coil 29 and thus changing the magnetic field generated by the electromagnetic coil 29 to control the viscosity of the electrorheological fluid inside the electromagnetic piston cylinder 18 and thus control the damping of the electromagnetic piston cylinder 18, thereby adjusting the downward pressure of the adjustable damping upper roller 3 on the cloth. After the cloth passes through the metal heating roller 7 and the nylon roller 27, the coating is firmly fixed on the cloth and the cloth is also calendered (single-layer coating plus calendering process is completed). Finally, the processed cloth is transported out; the above steps can be repeated for the second use.
