[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] Among the existing automatic unpacking devices, one type uses a gripping mechanism to grab the material when feeding it. However, the trigger mechanism of this gripping device is triggered by a cylinder, which increases the weight of the gripping mechanism, thereby limiting the single gripping weight of the gripping mechanism. In addition, the increase in the investment in power equipment will also increase the production cost of the equipment and the subsequent maintenance cost. Please refer to Figure 1-Figure 5 The present embodiment provides a continuous automatic unpacking platform, which can save the addition of power equipment, increase the weight of a single grab and reduce the investment in production and maintenance costs. The device includes two symmetrically distributed support frames 1 as a support base, and a clamping and grabbing mechanism 6 for grabbing the packaging bag is provided between the two support frames 1. The clamping and grabbing mechanism 6 includes a connecting frame 601 provided between the two support frames 1, and both sides of the connecting frame 601 are fixedly connected to a stabilizing frame 602, and both sides of the connecting frame 601 are fixedly connected to a flip support shaft 603, and the connecting frame 601 is provided with a The clamping trigger assembly 604 that triggers the clamping and grasping mechanism 6 to grasp, the clamping trigger assembly 604 includes a plurality of flip rods 6041 rotatably connected to the outside of the two flip support shafts 603, during which the flip support shafts 603 can provide support for the flipping of the flip rods 6041, and the two opposite flip rods 6041 are rotatably connected, and the other end of the flip rod 6041 is slidably connected to the interference rod 6042, and the bottom ends of the plurality of interference rods 6042 on the same side are fixedly connected by a parallel plate 6043, and a connecting rotating rod 6044 is rotatably sleeved in the middle of the connection of the plurality of flip rods 6041.

[0029] The parallel plate 6043 contacts the material packaging bag. As the parallel plate 6043 contacts the packaging bag, the parallel plate 6043 will push the interference rod 6042 fixed to it to slide upward. At that time, the flip rod 6041 slidingly connected to the interference rod 6042 will flip upward with the flip support shaft 603 as support, and the other end of the flip support shaft 603 will move downward, while driving the connecting rotating rod 6044 sleeved on its inner side to move downward together.

[0030] In order to ensure that the clamping trigger assembly 604 can be more stable and reset when sliding down, the two ends of the outer side of the connecting rod 6044 are fixedly connected with sliding stabilizing blocks 6045, and the two ends of the inner side of the connecting frame 601 are fixedly connected with stabilizing slide rails 6046. In order to improve the stability of the sliding stabilizing block 6045 when sliding, the two sliding stabilizing blocks 6045 are respectively slidably installed inside the two stabilizing slide rails 6046, and a reset spring 6047 is fixedly connected between the sliding stabilizing block 6045 and the stabilizing slide rail 6046. The reset spring 6047 can reset the sliding stabilizing block 6045.

[0031] During the downward movement of the connecting rotating rod 6044, the sliding stabilizing blocks 6045 fixedly connected at both ends of the connecting rotating rod 6044 move downward inside the stabilizing slide rail 6046, which can ensure the stability of sliding. At the same time, the reset spring 6047 inside the stabilizing slide rail 6046 can also reset after the parallel plate 6043 loses its resistance.

[0032] In order to be able to grab the packaging bag. A grabbing and fixing assembly 605 for grabbing packaging bags is provided between the two stable frames 602. The grabbing and fixing assembly 605 includes several horizontal frames 6051 fixedly connected between the two stable frames 602. Both ends of the inner side of the horizontal frame 6051 are slidably connected with an adapter sleeve 6052. One end of the adapter sleeve 6052 is slidably connected with a connecting rod 6053. The other end of the connecting rod 6053 is fixedly connected with a grabbing bent rod 6054, which can penetrate into the interior of the packaging bag by rotation to achieve grabbing. The distance between the two parallel plates 6043 and the ground is smaller than the distance between the several grabbing bent rods 6054 and the ground. In order to make the parallel plates 6043 contact the packaging bag first when moving downward, the other end of the adapter sleeve 6052 is rotatably connected with a connecting rod 6055, and one end of the two connecting rods 6055 inside the same horizontal frame 6051 is rotatably connected, and the connection between the two connecting rods 6055 is rotatably sleeved on the outside of the connecting rotating rod 6044.

[0033] As the connecting rotating rod 6044 moves downward, the connecting rotating rod 6044 will drive several connecting rods 6055 connected to its outer side to move, and the connecting rod 6055 will drive the adapter sleeve 6052 connected to its other end to slide on the inside of the cross frame 6051 when moving downward, and the adapter sleeve 6052 will push the top of the parallel plate 6043 connected to its other end to rotate when sliding, and the parallel plate 6043 will rotate with its middle part and the cross frame 6051 as support, and at the same time drive the grabbing bent rod 6054 fixed at its bottom end to rotate toward the other end, so as to penetrate into the interior of the packaging bag, thereby achieving the grabbing of the packaging bag.

[0034] Example 2

[0035] On the basis of Example 1, Example 1 solves the problem of low single grabbing weight of the grabbing mechanism, but there is still the problem of being unable to separate the material from the packaging bag. Figure 1-Figure 5 As shown, the specific implementation process is as follows: in order to split the packaging bags and collect the packaged materials in a centralized manner, an unpacking mechanism 7 for splitting the packaging bags is provided between the support frames 1, and the unpacking mechanism 7 includes a collecting hopper 701 provided between the two support frames 1, and a feed window 702 is installed in the middle of the top of the collecting hopper 701. In order to collect the materials inside the packaging bags, a plurality of unpacking blades 703 are fixedly connected to one side of the top of the collecting hopper 701. In order to open the clamped packaging bags, the top of the collecting hopper 701 is fixedly connected to limiting baffles 704 on both sides of the feed window 702. In order to limit the clamping state of the clamping and grabbing mechanism 6, a discharge pipe 705 is fixedly connected in the middle of the bottom of the collecting hopper 701, and a packaging bag discharge plate 706 is fixedly connected to the end of the outer side of the collecting hopper 701 away from the unpacking blades 703, in order to guide the discharging of the packaging bags.

[0036] In order to lift and move the clamping and grasping mechanism 6, transmission slide rails 2 are fixedly connected on both sides between the two support frames 1, and fixed plates 3 are slidably connected on the inner sides of the two transmission slide rails 2. A downward pressure cylinder 5 is installed in the middle of the top of the fixed plate 3, and the extended end of the downward pressure cylinder 5 passes through the fixed plate 3 and is connected to the top of the connecting frame 601.

[0037] A translation cylinder 4 is installed through the base in the middle of the outer side of one end of a support frame 1. The translation cylinder 4 passes through the support frame 1 and is fixedly connected to the outer side of one end of the fixed plate 3. Guide rods 606 are fixedly connected to the four corners of the top of the connecting frame 601. The tops of the four guide rods 606 all pass through and extend to the outer side of the top of the fixed plate 3, which can provide stable support for the clamping and grasping mechanism 6 during the downward movement.

[0038] By pressing the cylinder 5 downward, the clamping and grabbing mechanism 6 connected to its bottom end can be lifted, thereby lifting the packaging bag grabbed by the clamping and grabbing mechanism 6. During this period, since the packaging bag is grabbed, the weight of the packaging bag itself will pull the clamping trigger component 604 downward, so the clamping trigger component 604 will not reset, and the translation cylinder 4 will drive the fixed plate 3 to move, and at the same time drive the packaging bag clamped under the fixed plate 3 to move, until the grabbed packaging bag enters the top of the collecting hopper 701. At that time, the unpacking blade 703 on one side of the top of the collecting hopper 701 will open the passing packaging bag, and wait for the packaging bag to move to the top of the feed window 702. Afterwards, the material inside the packaging bag will enter the collecting bucket 701 through the feed window 702. During this period, the limiting baffles 704 on both sides of the middle of the top of the collecting bucket 701 can limit the clamping and grabbing mechanism 6 to prevent the clamping and grabbing mechanism 6 from suddenly resetting due to the disappearance of the grabbing heavy object, thereby causing the packaging bag to be left at the top of the collecting bucket 701. After the clamping and grabbing mechanism 6 is separated from the limiting baffle 704, the clamping and grabbing mechanism 6 will be reset. At that time, the packaging bag will be separated due to the opening of the clamping and grabbing mechanism 6, and then slide to the two ends of the outer side of the collecting bucket 701 through the packaging bag discharge plate 706 for unified collection.
