After the horizontal feeding device, heat sealing device, film supporting device, and negative pressure film suction device are reset to the initial state, the angle locking device of the coil conveying positioning device is unlocked, and the angle adjusting device works, driving the discharge frame to lay flat and roll The material rolls down from the coil material conveying positioning device under gravity and is transported out of the working platform, and enters the subsequent processing.
