technical field

The winding roller at the gear motor 2 that has completed the winding first squeezes the third baffle plate 47 downward, and then slides forward along the lower gap to complete the winding. After the rolling roller no longer squeezes the third baffle plate 47, the spring sheet 48 pushes the third baffle plate 47 to reset, and after the electric push rod 44 pushes the connecting frame 45 to move to the front, the uppermost end of the upper side gap just passes through. For a reel, the electric push rod 44 immediately drives the connecting frame 45 to move backwards.

To ensure that the incision of the film is flat, after the cutting motor 617 and the saw blade 619 cut the film, the upper electric guide 612 drives the two to reset, and then the operator starts the rewinding part 4 to replace the reel, and limit the position when the reel is replaced. The baffle 41 moves forward to prevent the L-shaped connecting rod 61 from moving backward, so the L-shaped slider 67 will not drive the parts and the cutting and gluing assembly on it to reset, so as to prevent the finished reel from falling down. The adhesive film is damaged by the saw blade 619. After the reel is replaced, the positioning wheel 65 is not limited by the adhesive film and is reset to the rear.

As shown in FIG. 11 and FIG. 12 , the one-way stopper includes a spring block 56 , and two spring blocks 56 are symmetrically arranged up and down. 52 is provided with a card slot in the upper direction, and the spring block 56 cooperates with the card slot of the rotating support shaft 52 to limit the position. A spring limit rod 57 is provided, the spring block 56 is limitedly matched with the spring limit rod 57, and a pressing block 58 is arranged symmetrically through the middle of the rotating handle 54, and the pressing block 58 releases the limit on the spring block 56 through the spring limit rod 57. The opposite end of the pressing block 58 is in position limit fit with the right end of the adjacent spring limit rod 57 .

Due to the different width models of the EVA packaging film, the diameter and width of the reels used are not exactly the same. Therefore, the reels with different diameters are fixed by the reel assembly 5, which is convenient for the fixing of the reels and the winding of the film. When the reel is fixed on the reel assembly 5, the reel is passed from the right end of the support rod 51 to the upper part, and the operator directly rotates the rotating handle 54 counterclockwise. The clamping slot is limited. Through the cooperation of the limit slot 59 and the upper limit pin of the support pad 55, the two support pads 55 in one group are rotated oppositely, and the reel is centered and fixed on the In the middle of the support rod 51, the rotating handle 54 no longer rotates counterclockwise, and the spring block 56 is limited by the clockwise position of the groove on the rotating support shaft 52. So far, the fixing of the reel is completed. When pulling out, the operator makes the reel assembly 5 separate from the reel. At this time, the operator squeezes the two pressing blocks 58, and the two pressing blocks 58 drive the adjacent spring limit rods 57 to move to the right, and the spring limit rods 57 The left end releases the limit on the spring block 56. At this time, the spring block 56 loses the limit cooperation with the slot on the rotating support shaft 52. The operator turns the rotating handle 54 clockwise to make the support pad 55 lose its fixation to the reel, and then The support rod 51 is withdrawn from the reel.

The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned embodiments. Within the knowledge scope of those skilled in the art, various modifications can be made without departing from the spirit of the present invention. kind of change.
