In the first embodiment, as shown in fig. 1, 2, and 3: a front turning plate 2 is rotatably arranged on two sides of the front part of the frame 1, a bag pressing hook 21 is arranged below the middle of the front side of the front turning plate 2, two notches 22 are arranged on the rear side of the front turning plate 2, and the left side and the right side of the front turning plate 2 are connected with a swinging device; two groups of sliding blocks 64 are respectively arranged at the two sides of the rack below the rear part of the front turning plate 2 in a front-back manner, a guide rail 65 is respectively arranged on each group of two sliding blocks 64 in a vertical sliding manner, so that two guide rails 65 capable of sliding up and down are respectively arranged at each side of the rack 1, the lower ends of the two guide rails 65 are respectively arranged on the sliding seat 62, the bracket 61 is arranged at the upper end, and a rotating wheel 66 is arranged at the front-back middle position of the sliding seat 62, so that two groups of frames capable of sliding up and down are respectively formed at the left side and the right; two rectangular supporting plates 5 are arranged on the two supporting seats 61 at intervals in the front-back direction, a gap is formed between the two supporting plates 5 at an interval, the gap corresponds to the inserting plate 3 up and down, and one sides of the two supporting plates 5 facing to the gap are respectively provided with a rubber plate 51; two swing arms 63 are arranged, pin shafts 67 are respectively arranged on two sides of the rack 1, the middle positions of the two swing arms 63 are respectively rotatably arranged on the pin shafts 67, springs 68 are respectively connected and arranged between the rear ends of the two swing arms 63 and the rack 1, and cylinders 6 are respectively arranged on the rack below the springs 68 and the pin shafts 67; a rotating shaft 42 is transversely and rotatably arranged on the left and right sides of the machine frame 1 below the front turning plate 2, pressing rods 4 are respectively arranged on the rotating shaft 42 at positions corresponding to the turning plate notches 22 on the front turning plate 2 up and down, a rocker arm 43 is arranged at one end of the rotating shaft 42, and an air cylinder 41 is arranged between the rocker arm 43 and the machine frame 1; an air cylinder 61 is arranged on the corresponding upper frame between the two supporting plates 5, and an inserting plate 3 is connected to the air cylinder rod of the air cylinder 61.
The specific working process is as follows: as shown in fig. 4, in the initial state, the cylinder rod of the air cylinder 6 is retracted, the front end of the swing arm 63 tilts up under the pulling of the spring 68 and the slide carriage 61, the guide rail 65, the bracket 61 and the two support plates 5 slide upwards along the slide block 64 through the rotating wheel 66, because the height of the two support plates 5 is basically consistent with that of the front overturning plate 2 due to the limiting effect of the limiting pin 69; when the manipulator 11 clamps the rear end of the plastic bag 7 and moves to the upper surface of the pallet 5, the middle part of the plastic bag 7 cannot droop due to the support of the pallet 5, and because the lower surface of the plastic bag 7 can be in contact with the upper surface of the pallet 5, the plastic bag 7 can generate friction with the pallet 5 in the process of moving backwards to form certain damping, so that the front part of the plastic bag 7 cannot drift backwards indefinitely due to inertia when the manipulator 11 stops, and the material can be discharged accurately (as shown in fig. 4); after the manipulator 11 has laid down and returned the plastic bag 7, it is also generally necessary for the plastic bag with two handles to be folded onto the front flap 2 (slightly); before the front turning plate 2 is turned backwards, the bag pressing hook 21 swings backwards to press and fix the head part of the plastic bag 7 on the front turning plate 2, so that the state shown in fig. 5 is formed; then, the front turning plate 2 swings backwards under the driving of the driving mechanism, the bag pressing hook 21 releases and resets after the front turning plate 2 swings backwards to be in an upright state, when the front turning plate 2 is turned over to be in contact with the plastic bag 7 on the supporting plate 5, the downward pressure of the front turning plate 2 can overcome the elastic force of the spring 68 to enable the supporting plate to move downwards, so that the plastic bag 7 can be turned over and folded on the two supporting plates 5 by the front turning plate 2, and the plastic bag 7 is clamped by the downward pressure of the front turning plate 2 and the upward lifting force of the spring 68 to form stronger extrusion; then, the air cylinder 41 opens and pulls the rocker arm 43 to make the rotating shaft 42 drive the pressing rod 4 to swing, and the folded and formed plastic bag 7 is pressed through the flap notch 22, so as to form the state shown in fig. 6. At this time, due to the action of the spring 68, the plastic bag 7 is pressed between the front turning plate 2 and the supporting plate 5 to form elastic pressing, so that the folding line position of the plastic bag 7 is elastically pressed to form a stronger crease, the rebound is reduced, and the folding stability is improved. Then, the cylinder 6 is opened, the cylinder rod extends to abut against the rear end of the swing arm 63, then the front turning plate 2 returns to reset, and after the front turning plate 2 returns, although the downward pressure is lost, the cylinder 6 can abut against the rear end of the swing arm 63, so that the supporting plate 5 is not lifted again, and is in a relatively static state, and a state shown in fig. 7 is formed; and then the inserting plates 3 move downwards under the driving of the air cylinders 31 to insert the front and rear middle positions of the plastic bag 7 into the gap between the two supporting plates 5 to form folding, and the folding work of the plastic bag is finished.
The second embodiment is different from the first embodiment in the lifting mechanism, as shown in fig. 8 and 9: the lifting mechanism is composed of two cylinders 60 with guide rods, one cylinder 60 with guide rods is respectively arranged on the frame 1 at the position corresponding to the downward direction of the inserting plate 3, and the support plates 5 are arranged on the guide rod seats of the two cylinders 60 with guide rods at intervals. The cylinder 60 with the guide rod can be composed of a guide rod, a cylinder and a guide rod seat, and a three-shaft cylinder or a double-rod cylinder can be directly purchased from the market; and the exhaust holes of the cylinder with the guide rod are respectively provided with an adjusting valve so as to control the descending speed of the supporting plate 5.
The working process of the second embodiment is as follows: in the initial state, the two cylinders 60 with the guide rods are opened, the cylinder rods are lifted, the heights of the supporting plate 5 and the front turning plate 2 are basically kept consistent, when the front turning plate 2 is turned backwards to the upper surface of the supporting plate 5, the cylinders 60 with the guide rods start to release, and due to the adjusting function of the adjusting valve, the descending speed of the supporting plate 5 is lower than the pressing speed of the front turning plate 2, so that the plastic bag 7 can be squeezed between the front turning plate 2 and the supporting plate 5, and a certain indentation is formed at the position of a folding line.
