Detailed Description
As shown in fig. 1, this kind of plastic bag blank pressing mechanism is including left slide 1 and right slide 2, be equipped with left blank pressing spare 10 on the left slide 1, left blank pressing spare 10 has directional right left pressure to indicate 11, left slide 1 can slide left and right and set up on support 4 (set up on support 4 and control the guide rail 3 that extends, left slide 1 sets up on the guide rail 3), be equipped with the power supply that drives left slide 1 and remove on support 4, be equipped with right blank pressing spare 20 on the right slide 2, right blank pressing spare 20 has directional left right pressure to indicate 21, right slide 2 can slide left and right and set up on support 4 (set up on support 4 and control the guide rail 3 that extends, right slide 2 sets up on the guide rail 3), be equipped with the power supply that drives right slide 2 and remove on support 4, support 4 is connected with the transmission of lift power supply 7 that drives support 4 and reciprocate. It should be noted here that one power source may be used for driving the left slide 1 and the right slide 2, or two independent power sources may be used, for example, the first power source 5 in fig. 2 drives the left slide 1 to move, and the second power source 7 drives the right slide 2 to move.
The operation principle of the plastic bag edge pressing mechanism is as follows: when the plastic bag is in place, the power source drives the left edge pressing piece 10 to move rightwards, the power source drives the right edge pressing piece 20 to move leftwards, so that the left pressing finger 11 of the left edge pressing piece 10 comes above the left edge of the plastic bag, the right pressing finger 21 of the right edge pressing piece 20 comes above the right edge of the plastic bag, then the lifting power source 7 drives the support 4 to descend, and therefore the left pressing finger 11 and the right pressing finger 21 are pressed on two sides of the plastic bag. The plastic bag can be turned by the turning plate, and the plastic bag cannot move in the turning process because the left pressing finger 11 and the right pressing finger 21 press the plastic bag, so that the plastic bag can be folded completely.
In order to improve the efficiency, two bags are folded at one time, the left edge pressing pieces 10 of the utility model are provided with two, the two left edge pressing pieces 10 are connected together, the two left edge pressing pieces 10 move together, and the left sides of the plastic bags at two sides can be pressed at the same time; and the two right blank holders 20 are connected together, and the two right blank holders 20 move together and can press the right sides of the two plastic bags.
The utility model also provides a roll over bagging apparatus of using this plastic bag blank pressing mechanism, as shown in figure 2, this roll over bagging apparatus includes returning face plate 8, broken line board 9 and backup pad 81, and returning face plate 8 is connected on pivot 80, and pivot 80 is connected with drive pivot 80 pivoted upset power supply transmission, and broken line board 9 is connected with the broken line power supply transmission that drive broken line board 9 reciprocated, is equipped with as above in the front side of pivot 80 plastic bag blank pressing mechanism, has the interval between the left blank pressing piece 10 of plastic bag blank pressing mechanism and the pivot 80, has the interval between the right blank pressing piece 20 of plastic bag blank pressing mechanism and the pivot 80, has the interval between backup pad 81 and the pivot 80.
The working principle of the bag folding device is as follows: as shown in fig. 2, the plastic bag S is placed on the turning plate 8 and the support plate 81, before the folding plate 9 moves downward, the lifting power source 7 drives the support 4 to move downward, the left pressing finger 11 and the right pressing finger 21 are positioned at two sides of the plastic bag, because the left pressing member 10 and the rotating shaft 80 have a space therebetween, the right pressing member 20 and the rotating shaft 80 also have a space therebetween, and the support plate 81 and the rotating shaft 80 have a space therebetween, after the folding plate 9 moves downward, the folding plate 9 inserts the bag body part of the plastic bag between the support plate 81 and the rotating shaft 80, so that the bag body of the plastic bag forms a concave line, the turning plate 8 turns over, the bag body is bent and folded along the concave line, and then the left pressing member 10 and the right pressing member 20 move to two sides, and the plastic bag is not pressed, and the lifting power source 7 drives the support 4 to move upward. Because the turnover part of the plastic bag is always pressed in the turnover process, the plastic bag can be completely and smoothly folded.
