When the slide cylinder 102 is in an extended state and is driven to reset by the driving cylinder, the second gluing (gluing of the rear end of the front film sheet) is completed. Repeating the gluing action, i.e., gluing the first end of the front film sheet, stretching after the film drawing mechanism 200, and gluing the tail end of the front film sheet by the gluing assembly 100. The specific process is as follows: Figure 4 Schematic diagram;

[0077] Film paper unwinding: the film paper in a roll is connected by the unwinding roller 2, and the unwinding end of the film paper in a roll passes through the gluing mechanism and the cutting mechanism 300. The film paper unwinding end with glue on the first end and the tail end is stretched downward to the required length by the film drawing action of the film drawing mechanism 200, and the film paper is clamped and positioned by the clamping and positioning assembly 500;

[0078] Suction limiting: when the film paper is stretched to the set length by the film drawing mechanism 200, the film paper can be suction-limited by the second suction plate 11 and the third suction plate 12;

[0079] Cutting: the cutting cylinder 302 can drive the cutter 303 to cut along the width direction of the film paper, so that the cut film paper forms a film sheet for leather;

[0080] Leathering: the paper tube is driven by the feeding conveying mechanism to move along the incoming material conveying channel to the leather working station. One side of the paper tube is pressed on the film sheet, and the film sheet is attached along the top and bottom of the paper tube under the continuous driving of the feeding conveying mechanism. The two ends of the film sheet converge to the other side of the paper tube along the top and bottom attachment. The lower roller cylinder 404 is driven to rise by the lower roller cylinder 402 to pass through the avoidance notch 15 to roll-press the first end of the film sheet to the side of the paper tube. The lower roller cylinder 402 drives the lower roller cylinder 404 to descend and retract below the avoidance notch 15. The upper roller cylinder 403 is driven to descend by the upper roller cylinder 401 to roll-press the tail end of the film sheet to the side of the paper tube and attach with the first end, thereby completing the leathering packaging of the paper tube;

[0081] When the product cover is completed, the blanking push plate 17 is driven by the blanking cylinder 16 to move to the blanking channel, so that the blanking push plate 17 can push the paper tube on the cover station to the blanking channel for blanking.

[0082] In summary, the automatic cover mechanism realizes the automatic production of the processes of automatic unwinding, gluing, stretching, cutting, covering and finished product blanking of the film paper through the setting and cooperation of various features, improves the production efficiency, product quality and automation degree, and reduces the error and labor intensity of manual operation.
