The front tensioning block is installed and connected with the corresponding part of the packaging machine, so that the stability of the overall motion is ensured.
The grab bar may be a suction cup-like device capable of attracting the bag.
The two tensioning mechanisms are symmetrically arranged on two sides of the upper suction bag mechanism.
The tensioning connecting rod is driven to rotate through the tensioning cam, the tensioning opening and closing adjusting rod is further pulled, the tensioning rod is driven to rotate, and therefore the tensioning driving rod swings left and right, and the tensioning sliding block can be pushed to move on the transverse sliding rail. The bag is squeezed from two sides to the middle by the simultaneous action of the tensioning mechanisms on two sides.
In the invention, the specific movement stroke of the zipper opening cam of the horizontal machine needs to be set correspondingly. As shown in the attached figure 7, the arrangement angle of the horizontal machine zipper opening cam in the figure is taken as a reference for explanation, and the anticlockwise rotation is taken as a direction.
Total 6 strokes:
1. the first stroke takes 115 degrees, at which time the upper suction cups assembled with the zipper opening mechanism remain open and stationary and the upper row of the packaging machine feeds the bag.
2. The second stroke occupies 65 degrees, at the moment, the upper suckers move from the farthest state to the nearest state, and the two upper suckers on the two sides of the blowing nozzle are folded.
3. The third stroke occupies 30 degrees, at the moment, the upper sucker keeps static, the vacuum is opened by pumping air, and the bag is sucked.
4. The fourth section of stroke occupies 35 degrees, and the upper sucker sucks the bag and is driven to move the first section of stroke, so that a small opening is opened at the top of the bag.
5. The fifth section of stroke occupies 45 degrees, at the moment, the upper sucker keeps the static state that a small opening is opened at the top of the bag, and the cylinder of the zipper opening mechanism moves to drive one side of the bag opening strip to extend into the bag, so that the bag clamping action is completed.
6. The sixth stroke takes 70 degrees, at which time the vacuum of the upper suction cup is broken and the bag is no longer sucked. The zipper opening mechanism keeps the bag clamped state and continues to move for the second section of travel, the zipper of the bag can be torn off in the moving process, and meanwhile the bag opening is further opened. And the blowing nozzle is opened during the section of the stroke, so that air enters the bag as soon as possible to finish opening the bag.
The specific actions are as follows:
1. other mechanisms in the packaging machine deliver the bags to the bag opening station, i.e. the position below the blowing nozzle is located in the middle of the two tensioning mechanisms. The upper sucker and the lower sucker are located at the farthest positions at the moment, the bag is not sucked, and the two ends of the bag are grabbed by the grabbing rod piece in the tensioning mechanism.
2. The zipper opening cam and the tensioning cam of the leveling machine are driven by the main shaft to synchronously rotate anticlockwise, the zipper opening cam of the leveling machine drives the bag suction main connecting rod to rotate around the main fixing shaft, the lower opening and closing adjusting rod is driven to move downwards, the lower front sliding block is pushed by the lower front connecting rod, and the lower rear sliding block is pulled by the lower rear connecting rod to be close to each other, so that the lower front sliding block and the lower rear sliding block move to the nearest position away from the bag. Meanwhile, the upper opening and closing adjusting rod is pulled to move downwards, and the upper suckers on the upper front sliding block and the upper rear sliding block are driven to mutually approach and move to the nearest position of the bag. The upper sucker opens the vacuum to suck the bag, and the lower sucker does not open the vacuum at the moment and does not temporarily suck the bag. At this moment, the upper 2 suckers just cling to the bag, the lower sucker can cling to the bag through the bag, but the spring is compressed due to the fact that the spring is arranged on the lower sucker, and therefore the lower sucker also just clings to the surface of the bag.
3. The zipper opening cam of the horizontal machine finishes the first section of stroke, the upper sucker moves a small distance, the top of the bag is driven to move in the moving process, and a small opening is opened on the bag at the moment (due to the existence of the zipper, the part below the zipper of the bag cannot be opened). Meanwhile, the lower sucker is in a compressed state because the spring is in a compressed state, the stroke only offsets the compression amount of the spring, the spring is in a natural state, and the lower sucker still just clings to the bag at the moment actually.
4. After the step 3 is finished, the operation is stopped for a while, the upper sucker keeps the top of the bag in a static state with a small opening, and then the cylinder in the zipper opening mechanism moves to drive the bag opening strip to extend into the opening position at the top of the bag and clamp the bag.
5. The zipper opening cam of the horizontal machine moves along the second section of stroke, the zipper opening mechanism keeps a bag clamping state at the moment and then moves to the farthest position, the zipper of the bag can be torn off due to continuous separation of two sides of the top opening of the bag in the moving process, and meanwhile, the bag opening is also pulled open, so that the bag opening action is completed. When the bag mouth is opened, namely the second section of stroke, the air blowing nozzle is opened to inflate the bag, and the bag is closed after the second section of stroke is finished, so that more air can enter the bag more quickly when the bag is opened. In addition, when the second stroke is carried out, the lower suction disc is also opened to suck the bag, so that the bottom of the bag is also sucked, and the bag is ensured to be filled with air. Furthermore, during the second stroke, the tensioning cam in the tensioning mechanism is just in the process of squeezing the grabbing rod pieces clamping the two ends of the bag towards the middle, namely the bag is opened at the same time, and the two ends are closed towards the middle.
And 5, after the step 5 is completed, conveying the bag away, conveying a new bag at the same time, completing a motion cycle, and then repeating the step 1 to enter the next cycle.
Although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications, equivalents, improvements, and the like can be made in the technical solutions of the foregoing embodiments or in some of the technical features of the foregoing embodiments, but those modifications, equivalents, improvements, and the like are all within the spirit and principle of the present invention.
