and limited, the compatibility and the practicability of the device are improved, and then the user controls the servo motor 7 to be electrified to work, the servo motor 7 is electrified to drive the moving plate 9 in threaded connection with the servo motor to start moving, the cutting knife 11 moves along with the servo motor, the servo motor 7 can be controlled to stop working after the cutting knife 11 moves to a proper position, then a user pulls the ETFE cast film to the top of the driving roller 2, the driving roller 2 rotates to drive the ETFE cast film to move backwards, the pressing roller 5 limits the position of the pressing roller, two sides of the ETFE cast film are respectively positioned in the two guide frames 3, the ETFE cast film starts to contact with the cutting part 14 of the cutting knife 11 along with the continuous rotation of the driving roller 2, the ETFE cast film is cut into two parts by the cutting part 14, the waste edge is guided to one side along with the arc part 15 of the cutting knife 11, so that the middle part of the ETFE cast film continuously moves between the two moving plates 9, and the waste material is guided to the winding devices 16 at two sides by the cutting knife 11, when the slitter edge is in contact with the cutting knife 11, the limiting wheel 13 on the cutting knife 11 can also press the slitter edge tightly, so that the slitter edge is in contact with the supporting plate 12, after the scrap material enters the collecting box 1601, a user controls the air pump 1606 and the winding motor 1602 to work in an electrifying manner, the air pump 1606 generates suction force to pump out air in the top inner cavity 1604, negative pressure is formed when air in the top inner cavity 1604 gradually decreases along with continuous work of the air pump 1606, so that the suction hole 1605 at the top generates suction force, the winding motor 1602 drives the winding barrel 1603 fixedly connected with the winding motor 1602 to rotate synchronously after being electrified, the metal barrel 1608 sleeved on the winding barrel 1603 rotates along with the winding barrel 1603, so that the position of the suction hole 1605 continuously rotates clockwise, the slitter edge can be in contact with the metal barrel 1608 after entering the collecting box 1601, the film can be adsorbed by the suction hole 1605 along with rotation of the metal barrel 1608, so that the waste material can be wound on the metal barrel 1608 continuously, when the waste material in the collecting box 1601 is too much, the user controls the electromagnetic plate 1607 to power off and lose magnetic force, the user cuts the film and then detaches the partition 1609, and then draws the metal tube 1608 out of the winding tube 1603, so that the metal tube 1608 carries the wound waste material to separate from the winding tube 1603, the user can prepare a plurality of metal tubes 1608 in practical application, when the metal tube 1608 for winding the waste material is detached, the new metal tube 1608 can be sleeved on the winding tube 1603, then the electromagnetic plate 1607 is controlled to generate magnetic force to be adsorbed to the metal tube 1608, and then the winding work can be continued, the setting of the winding device 16 can improve the waste material collecting efficiency of the edge cutting device, thereby improving the edge cutting efficiency of the ETFE cast film, when the cutting knife 11 needs to be polished or replaced in service time, the user pulls the overlong pull rod 1006, and the pull rod 1006 drives the limit plate 1005 to move backwards, at this time, the return spring 1004 is stressed to begin to contract, the limiting plate 1005 begins to move away from the top of the sliding groove 1001 and the sliding strip 1002 along with the continuous pulling of a user, so that the sliding strip 1002 can move inside the sliding groove 1001, then the user lifts the cutting knife 11 upwards to enable the sliding strip 1002 to move upwards inside the sliding groove 1001 until the cutting knife 11 is completely separated between the sliding strip 1002 and the sliding groove 1001, then the user lifts the new cutting knife 11 or the polished cutting knife 11 to the top of the moving plate 9, so that the sliding strip 1002 is aligned with the sliding groove 1001 and moves the cutting knife 11 downwards, the sliding strip 1002 slides into the sliding groove 1001 again to form primary positioning, then the user releases the pull rod 1006, at this time, the return spring 1004 starts to rebound without being stressed by hand, the limiting plate 1005 is pushed to the front side, so that the limiting plate 1005 is located at the top between the sliding strip 1002 and the sliding groove 1001, thereby make cutting knife 11 unable removal, the setting of installation device 10 can be convenient for the change of cutting knife 11 to reduce the time of changing cutting knife 11, increase the efficiency reduction personnel amount of labour of cutting edge, solved in the past the poor, the poor and cutter of edge cutting device garbage collection effect of ETFE curtain coating film and not have the problem of direction function of side cut efficiency.

The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
