[0047] Different from example one:

[0048] The cam exhaust mechanism comprises a push plate cylinder 6 connected to the large base plate and a slide rail three 2-3, the shaft end of the push plate cylinder 6 is connected with a vibration base plate 16, the vibration base plate 16 is installed on the slide rail three 2-3, the end of the vibration base plate 16 is hinged with an exhaust power plate 17, the slide rail three 2-3 is connected with a motor four 14 through a connecting plate, the shaft end of the motor four 14 is drivingly connected with a cam shaft 28 through a belt four 27, and the end of the cam shaft 28 is eccentrically and rotatably connected with the exhaust power plate 17. The cam exhaust mechanism is used as an air exhaust mechanism during the film winding process. The motor four 14 drives the cam shaft 28 to rotate through the belt four 27. The eccentric structure of the cam shaft periodically pushes the exhaust power plate 17, so that the exhaust power plate 17 swings back and forth around the hinge point. It should be understood that the end of the vibration base plate 16 can be connected with the exhaust power plate 17 through an elastic hinge to realize the elastic support connection of the two, and the film winding surface is subjected to high-frequency beating. The vibration base plate 16 is driven by the push plate cylinder 6 to slide along the slide rail three 2-3, so as to adjust the beating position of the exhaust power plate 17 and adapt to the film winding with different diameters. The high-frequency beating forces the air between the film layers to escape, and the vibration base plate can adjust the beating amplitude to avoid damaging the film.

[0049] During work, after the center pipe of the welded flow guide cloth with the film is transported to the specified position, the two end expansion rod cylinders of the base plate are extended to drive the expansion rod mechanism to fix the center pipe; the expansion rod rotation servo motor works to drive the center pipe expanded by the expansion rod to start rotating through the belt wheel, and the film is wound up; the push plate cylinder is extended to move the guide rail slide to move the exhaust power plate with the cam mechanism to the front of the film winding; the cam exhaust mechanism servo motor drives the cam mechanism to rotate, and the exhaust power plate connected with the cam mechanism starts to vibrate and beat the film winding being wound to make the air between the films escape; after winding to the specified number of turns, the push-up roller screw rod group moves the push-up roller cylinder to extend the two push-up rollers fixed on the push-up roller base to slowly withdraw; the push-up roller guide push-up roller mechanism starts to work to make the two push-up rollers simultaneously and uniformly extrude, which is beneficial to the film to better escape the air. At the same time, the double-servo expansion rod rotation servo motor mechanism can effectively prevent the film from deviating. The whole process realizes full-automatic winding.

[0050] The film element also provides a full-automatic winding method, which comprises the following steps:

[0051] 1. After the center pipe of the welded flow guide cloth with the film is transported to the specified position, the two end expansion rod cylinders of the base plate are extended to drive the expansion rod mechanism to fix the center pipe;

[0052] 2. The expansion rod rotation servo motor works to drive the center pipe expanded by the expansion rod to start rotating through the belt wheel, and the film is wound up;

[0055] 5. After the specified number of turns, push the roller servo motor work, driven by the push roller screw group moves, both ends of the push roller cylinder to keep the balance of the push roller;

[0056] 6. With the diameter of the film roll increases, the two top roller slowly back;

[0057] 7. Double servo rod rotary servo motor mechanism can effectively prevent the film from running off;

[0058] 8. Two top roller at the same time very evenly extruded to help the film better air exhaust.

[0059] The method can make the film element uniform stress during automatic winding process, not run off, exhaust film between air, film does not fold during the process of winding, greatly improve the yield of finished film.

[0060] The scheme can solve the problem of uneven stress leading to deviation of the film: the double guide roller 7 of the push roller mechanism is symmetrically distributed on both sides of the film roll, and the pressure is synchronized by the cylinder 8 to ensure that the pressure on both sides is consistent. The magnetic powder brake 12 adjusts the rotary resistance of the guide roller in real time, maintains the uniform tension of the film during winding, and eliminates the deviation caused by excessive unilateral tension.

[0061] The scheme can solve the problem of air residual leading to bulging or wrinkling:

[0062] The patting action of the cam exhaust mechanism, the high-frequency patting of the exhaust power plate 17 makes the film layers close tightly, forcing the air to exhaust. At the same time, dynamic extrusion cooperation, the push roller mechanism continuously applies pressure during winding, further compresses the film gap, and reduces the air residual space.

[0063] The scheme can improve the yield of automatic control:

[0064] Full process power coordination: through the automatic control of cylinder, motor, screw group, realize the accurate timing cooperation of clamping, rotating, extruding, exhausting, reduce the error of human intervention. Self-adaptive adjustment: cylinder 1, cylinder 2, push plate cylinder, etc. can automatically adjust parameters according to the diameter of the center tube and the thickness of the film, adapt to different production needs.

[0065] In summary, the mechanism ensures the stable winding of the center tube through axial clamping + circumferential rotation, solves the uneven force problem through symmetrical push rollers + magnetic powder brake, and completely discharges the interlayer air through cam beating + dynamic extrusion, finally realizes the high-quality winding of the film roll with tightness, no deviation and no wrinkles, and significantly improves the yield.
