detailed description

Referring to Fig. 1 , it is a control system of casting and rewinding pendulum pressure roller 60 of the present invention, which includes a main control programmable controller 10, a human-computer interaction terminal 20, a rewinding frequency converter 30, a rewinding motor 40, Air-liquid damping cylinder 50 and winding pressure roller 60, the human-computer interaction terminal 20 is electrically connected with the main control programmable controller 10 for setting and monitoring the variables inside the main control programmable controller 10, the main control can The programming controller 10 is respectively connected with the winding inverter 30 and the gas-liquid damping cylinder 50 to output control signals, and the winding inverter 30 is electrically connected with the winding motor 40 to adjust the speed and torque of the winding motor 40. The winding motor 40 is used to drive the winding shaft used for the winding material to rotate, and the gas-hydraulic damping cylinder 50 is used to drive the winding pressure roller 60 to approach or move away from the winding shaft.

Wherein, the rewinding frequency converter 30 adopts a closed-loop control vector frequency converter, the rewinding motor 40 includes a first rewinding motor 40 and a second rewinding motor 40, and the main control programmable controller 10 is connected with a group of radio eyes 70, used to detect the position of the material roll on the winding shaft. An induction electric eye 80 is arranged between the gas-liquid damping cylinder 50 and the winding pressure roller 60 , and the induction electric eye 80 is electrically connected with the main control programmable controller 10 to feed back the position of the winding pressure roller 60 .

The working principle of the present invention is: in the case of normal operation of the equipment, different winding methods are selected according to customer needs, and different methods should be used for different films to be more secure; during production, according to the differential and winding methods set in the program The integral formula calculates the length of the film with the machine speed, and then calculates the diameter of the winding with the thickness and speed of the film. The following will introduce the two winding modes of the present invention: gap winding and contact hand rolling.

(1) If gap winding is selected, the air-liquid damping cylinder 50 of the pressure roller 60 will slowly retreat at a constant speed and position every time the diameter of the roll increases (detected by the radio eye), so as to achieve the balance of tension and The uniformity of the film, the gap between the pressure roller 60 and the winding shaft can be set according to the needs;

(2) Contact rewinding. As the name suggests, the pressure roller 60 presses lightly on the rewinding shaft. According to the change of the diameter of the reel (detected by the induction electric eye), the pressure of the pressure roller 60 on the rewinding shaft is constant and can be set. Control the adjustment of the proportional valve, the pressure roller 60 is the tension output of the curve, so that the winding film can achieve the purpose of inner tightness and outer looseness, and the air-liquid damping cylinder 50 can achieve better results through the control of the main control programmable controller 10 , which is more suitable for the winding structure.

The above descriptions are only preferred implementations of the present invention, and the present invention is not limited to the above-mentioned implementations, as long as the technical solutions that achieve the purpose of the present invention by basically the same means fall within the protection scope of the present invention.
