The plastic bag ear folding mechanism 1 has the working principle as follows: as shown in fig. 5, when a stack of formed plastic bags is transferred by a mechanical clamp and then placed on the turning platform 21 of the plastic bag turning mechanism 2 (the mechanical clamp is the prior art, and the detailed structure of the plastic bag turning mechanism 2 is described below), two handles of the plastic bag are placed on the left ear supporting plate 111 and the right ear supporting plate 120, respectively, and then the vertical moving seat 12 moves down, the left ear pressing plate 121 and the right ear pressing plate 122 on the vertical moving seat 12 are pressed on the two handles of the plastic bag, respectively, because the left ear pressing plate 121 has a left ear pressing oblique edge 1210 corresponding to the left ear supporting oblique edge 1110, the right ear pressing plate 122 has a right ear pressing oblique edge 1220 corresponding to the right ear supporting edge 1120, when the left ear pressing plate 121 is lower than the left ear supporting plate 111 and the right ear pressing plate 122 is lower than the right ear supporting plate 120, as shown in fig. 12, the two handles of the plastic bag form an oblique folding line a, and then the left ear folding piece 13 moves to the right, the bag handle on the left side of the plastic bag is scraped to the right side along the folding line a, the right ear folding piece 14 moves to the left side, and the bag handle on the right side of the plastic bag is scraped to the left side along the folding line a, so that the two bag handles of the plastic bag are folded along the folding line a; finally, the horizontal sliding base 16 drives the vertical moving base 12 to move forward, the left lug pressing plate 121 and the right lug pressing plate 122 retreat, the vertical moving base 12 ascends again, and the horizontal moving base 11 moves backward, so that the turnover platform 21 can be turned over along the folding line b of the plastic bag body.
For increasing the efficiency, as shown in fig. 3, two sets of left ear supporting plates 111 and right ear supporting plates 120 are provided on the horizontal moving base 11, two sets of left ear pressing plates 121 and right ear pressing plates 122 are provided on the vertical moving base 12, and the left ear folding member 13 has two ear pressing plates connected in parallel and the right ear folding member 14 has two ear pressing plates connected in parallel. By the structure, the invention can simultaneously complete the ear folding of two bags at one time, thereby doubling the efficiency.
As shown in fig. 12, after the plastic bag handle is folded, the plastic bag body needs to be folded along a folding line b, and the plastic bag body is turned and folded by the plastic bag turning mechanism 2, however, before the plastic bag body is turned and folded, it is preferable to form a bending line (the folding line b is formed after the folding) on the plastic bag body in advance, so that the plastic bag body is folded along the bending line when it is turned. In order to make the plastic bag body form the bending line, so that the plastic bag body can be folded more easily, the invention is connected with the folding line board 15 on the vertical moving seat 12, and the lower end of the folding line board 15 is lower than the left lug pressing plate 121 and the right lug pressing plate 122. With this structure, when the vertical movement seat 12 moves down, the left and right lug pressing plates 121 and 122 press the handle portion of the plastic bag, and the folding line plate 15 presses the bag body portion of the plastic bag, as shown in fig. 2, because the turning platform 21 has a fall with the front position of the turning platform 21, the folding line plate 15 presses the bag body of the plastic bag down for a certain distance, so that a bending line is formed, and then the turning platform 21 turns over, so that the plastic bag body is bent and folded along the bending line, thereby forming the folding line b.
