The drum connecting piece 2 includes two spline shafts arranged in opposite rotation on the winding frame 1 and a spline rod axially inserted into the spline shafts. The winding drum 3 is provided with a spline insertion hole at the center of the end face. One end of the spline rod is inserted into the spline insertion hole. Two tooth rods are transversely and oppositely inserted into the winding frame 1. The two tooth rods are arranged in an up-down distribution inside the winding frame 1. A transmission tooth is rotatably arranged between the opposite faces of the two tooth rods. The tooth surface of the transmission tooth is engaged with the tooth surface of the two tooth racks, respectively. A second telescopic cylinder is used to linearly push one of the tooth racks to move.

[0040] Working principle: since the smoothing plate 63 is always pressed on the top of the hot melt adhesive film rolled in the winding drum 3 when the hot melt adhesive film is winding, it can ensure that the hot melt adhesive film is wound neatly and flatly, and avoid wrinkles to affect the quality of the hot melt adhesive film. When the hot melt adhesive film on the winding drum 3 is fully loaded, first control the servo motor to stop. Since the smoothing plate is always pressed at the contact point between the hot melt adhesive film and the winding drum 3, it is convenient to avoid the hot melt adhesive film on the winding drum 3 from spreading after the hot melt adhesive film is cut. Then rotate the bidirectional screw in counterclockwise direction, so that the two extraction hooks 43 driven by the bidirectional screw move away from each other until the distance between the two extraction hooks is greater than the distance between the two end faces of the winding drum 3. Then control the first telescopic cylinder 55 to retract, so that the hook tips of the extraction hooks 43 on the sliding beam 41 correspond to the insertion holes 7 on the end faces of the winding drum 3. Then rotate the bidirectional screw in clockwise direction, so that the two extraction hooks 43 driven by the bidirectional screw move close to each other until the hook tips are completely inserted into the insertion holes 7. Then control the end faces of the winding drum connecting piece 2 and the winding drum 3 to separate, so that the fully loaded winding drum 3 is completely hung between the two extraction hooks 43. Then deflect the free end of the extended guide rail 52 upward until the extended guide rail 52 is in horizontal state. Then insert the free end of the supporting arm 54 into the right angle in the limiting area to stably keep the extended guide rail 52 in horizontal state. Then control the first telescopic cylinder 55 to extend and push the sliding beam 41 to slide horizontally and linearly from the fixed guide rail 51 to the extended guide rail 52. The sliding beam 41 drives the extraction hooks 43 and the winding drum 3 to move synchronously until the winding drum 3 is completely located outside the winding frame 1. At this time, push the carrying trolley for transfer to the bottom of the winding drum 3. Then rotate the bidirectional screw in counterclockwise direction, so that the two extraction hooks 43 driven by the bidirectional screw move away from each other until the extraction hooks 43 are separated from the fully loaded winding drum 3. Thus the unloading operation of the fully loaded winding drum 3 is completed. The fully loaded winding drum 3 does not need to be manually carried, which reduces the labor intensity of workers and improves the efficiency of unloading operation. Then place the empty winding drum 3 between the two extraction hooks 43. Then rotate the bidirectional screw in clockwise direction, so that the two extraction hooks 43 driven by the bidirectional screw move close to each other until the hook tips are completely inserted into the insertion holes 7. At this time, the smoothing plate 63 is in contact with the top of the arc surface in the winding drum 3 under the action of gravity. Then control the first telescopic cylinder 55 to retract, so that the spline insertion hole on the end face of the empty winding drum 3 corresponds to the end face of the spline rod. Then control the second telescopic cylinder to retract and pull one of the racks, so that the two spline rods move close to each other through the power transmission of the transmission teeth and the other rack and the supporting vertical rod until the end faces are inserted into the spline insertion hole on the end face of the empty winding drum 3 and are in contact with the vertical surface in the spline insertion hole. Finally, after the broken section of the hot melt adhesive film passes between the smoothing plate 63 and the arc surface in the empty winding drum 3, start the servo motor to drive the spline shaft to rotate, so that the spline shaft drives the spline rod and the empty winding drum 3 to rotate synchronously. Since the gravity continues to act, the smoothing plate 63 is always pressed at the contact point between the hot melt adhesive film and the winding drum 3 during the winding process of the hot melt adhesive film.Avoid hot melt adhesive film when rolling appears wrinkle.
