Description

Technical Field

[0001] The invention belongs to the technical field of packaging equipment, and particularly relates to an intelligent sealing packaging machine. Background Art

[0002] Packaging bags are used to package various items. After factories use packaging bags to package raw materials or food, they usually use drawstrings to wrap the raw materials or food for easy transportation and storage. Existing large-diameter plastic packaging bags are generally tied manually, especially when using the pig's hoof buckle wrapping method. The operator must first tighten the bag opening with both hands, then use one hand to repeatedly wrap the drawstring around the bag opening, and then tighten it with both hands. Due to the different strength and carefulness of each person when manually tying the bag, mistakes are easy to make when wrapping and tightening the bag, resulting in problems such as loose packaging, easy scattering of items or moisture. Manual packaging is also costly and inefficient.

[0039] The working principle of the present invention is:

[0040] The tying packaging machine tightens the packaging bag through a clamping mechanism and a closing mechanism. When the packaging bag is transported to the bottom of the clamping mechanism through the packaging bag conveyor belt 37, the three telescopic cylinders 14 extend downward. At the same time, the gear clamp clamps the upper bag opening of the packaging bag, and the output shaft of the closing cylinder 25 extends, and the packaging bag is clamped and closed by the V-shaped clamp 26. At this time, the gear clamp opens and the telescopic cylinder 14 resets, and the packaging bag is synchronously transported to the rear winding mechanism by the closing mechanism and the packaging bag conveyor belt 37.

[0041] The pull rope is fed in by the rope feeding device and extends out from the guide plate 36. The end of the pull rope is tightened by the first clamping cylinder 9 at the output end of the second cross slide 7 and pulled to the side close to the clamping mechanism. At this time, the winding mechanism moves to the right side of the pull rope, and the winding mechanism is equipped with a side of the second clamping cylinder 20 facing the pull rope, and the second clamping cylinder 20 is flush with the pull rope through the first cross slide 6. The winding mechanism opens the second clamping cylinder 20, so that the pull rope passes through the clamping fingers of the second clamping cylinder 20. The second clamping cylinder 20 is clamped, and the first cross slide 6 moves upward and rotates 180° by the rotating motor 17 to form a ring knot for the pull rope. The lifting cylinder 18 extends out and pushes the guide frame 23 to move downward. The clamping pin 19 opens, so that the formed ring knot expands. At this time, the first clamping cylinder 10 on the second cross slide 7 extends out and extends into the intersection of the ring knot to close. The cylinder 10 is provided with an annular clamping jaw 11, and the pull rope can shuttle through the arc hole formed by the annular clamping jaw 11 to ensure that the pull rope completes the winding action. At this time, the packaging bag is transported to the winding mechanism, and the winding mechanism moves toward the packaging bag through the first cross slide 6. During the movement, the first cross slide 6 gradually descends and opens the second clamping jaw cylinder 20, so that the annular knot falls off from the second clamping jaw cylinder 20 and is inserted into the tied mouth of the packaging bag. At this time, the first clamping jaw cylinder 10 is opened, and the closing mechanism is reset to complete the first surrounding knot of the pig's hoof buckle. The rope pulling device controls the pull rope to straighten the rope, and then the winding mechanism and the first clamping jaw cylinder 10 repeat the previous action until the pig's hoof buckle is knotted. The third clamping cylinder 35 in the rope feeding mechanism moves to the side close to the cutting mechanism and tightens the pull rope. The cutting mechanism cuts the pull rope to complete the knotting packaging of a packaging bag. The pig's hoof buckle formed at the tied mouth of the packaging bag of the present invention is strong and reliable and not easy to fall off.

[0042] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
