DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The present invention provides an automatic unpacking device. Figure 1-4 As shown, it includes a grabbing robot 1, a tool mechanism 2 and a screening mechanism 3. The grabbing robot 1 is used for grabbing bags containing plastic particles and conveying the bags to the top of the tool mechanism 2. The tool mechanism 2 is used for cutting the bags grabbed by the grabbing robot 1 to make the plastic particles flow out of the bags. The screening mechanism 3 is arranged below the tool mechanism 2. The screening mechanism 3 is used for separating the debris left after the bags are cut from the plastic particles, thereby automatically completing the unpacking of the bags without manual unpacking, with high unpacking efficiency and reducing the labor intensity of the staff.

[0021] In this embodiment, the tool mechanism 2 includes a roller 21, and a plurality of annular blades 22 are arranged at equal distances on the outer wall of the roller 21 along its central axis direction. One end of the roller 21 is connected to a first driving device 23 for driving the roller 21 to rotate. The first driving device 23 is one of an electric motor, a hydraulic motor or a pneumatic motor. The roller 21 can be driven to rotate by the first driving device 23, and the roller 21 can drive the blade 22 to rotate to cut the bag.

[0022] In this embodiment, the screening mechanism 3 includes a grid 31 arranged below the tool mechanism 2 and a screen 32 arranged below the grid 31. The size of the holes on the grid 31 is larger than the size of the holes on the screen 32. The larger debris in the plastic particles can be separated through the grid 31, and the smaller debris in the plastic particles can be separated through the screen 32. At the same time, the grid 31 and the screen 32 are both equipped with a second driving device 33 for driving the grid 31 and the screen 32 to vibrate. The second driving device 33 is a vibration motor. The second driving device 33 can drive the grid 31 and the screen 32 to vibrate, so that the grid 31 and the screen 32 can more fully separate the debris in the plastic particles.

[0023] Preferably, it also includes a conveyor belt 4 for conveying bags to the grabbing robot 1. When conveying bags, the bags are placed on a pallet, and the pallet is placed above the feed end of the conveyor belt 4. The bags can be conveyed to the grabbing robot 1 through the conveyor belt 4. After the bags are taken away by the grabbing robot 1, the pallet is conveyed to the discharge end of the conveyor belt 4. At the same time, a pallet stacking mechanism 5 is provided at the discharge end of the conveyor belt 4. The pallet stacking mechanism 5 stacks the pallets output from the discharge end of the conveyor belt 4 together. When the pallets are stacked to a certain number, the pallets are picked up by a forklift and transported to a designated location.

[0024] It should be noted that a discharge hopper 6 is provided below the screening mechanism 3. After the debris in the plastic particles are separated, the plastic particles can enter the discharge hopper 6 and flow out through the discharge port at the bottom of the discharge hopper 6 to facilitate discharge.

[0025] In this embodiment, a waste bag collecting mechanism 7 is provided on one side of the screening mechanism 3, and the waste bag collecting mechanism 7 includes a collecting box 71. A feed hopper 72 is provided on the top of the collecting box 71. The grid 31 and the screen 32 are arranged downwardly in a direction close to the feed hopper 72. The debris separated from the plastic particles can flow into the collecting box 71 for collection. At the same time, when the grabbing robot 1 transports the bag to the designated position, the grabbing robot 1 loosens the bag, and the bag falls onto the grid 31. At the same time, the grid can be driven to vibrate through the second driving device 33 to separate the residual plastic particles in the bag from the bag. After separation, the bag enters the collecting box 71 for collection. At the same time, a screw rod 73 is provided inside the collecting box 71, and one end of the screw rod 73 is connected to the third driving device 74. The third driving device 74 is one of a motor, a hydraulic motor or a pneumatic motor. There is a discharge port 75 at one end of the collecting box 71. The screw rod 73 can be driven to rotate by the third driving device 74 to output the bag collected in the collecting box 71 through the discharge port 75.

[0026] Specific principle: When unpacking, place the bag containing plastic on the pallet, and place the pallet above the input end of the conveyor belt 4. When the conveyor belt 4 transports the bag to the grabbing machine 1, the grabbing manipulator 1 grabs the bag and transports the bag to the top of the knife mechanism 2. The knife mechanism 2 cuts the bag grabbed by the grabbing manipulator 1, so that the plastic particles flow out of the bag. The debris left after the bag is cut can be separated from the plastic particles through the screening mechanism 3. The separated plastic particles can flow out through the discharge hopper 6. The debris at the separation can enter the waste bag collection mechanism 7 for collection. After the material robot 1 transports the bag to the designated position, the material grabbing robot 1 releases the bag, and the bag falls onto the screening mechanism 3, separating the residual plastic particles in the bag from the bag. After separation, the bag enters the waste bag collecting mechanism 7 for collection, and at the same time, the pallet is transported to the discharge end of the conveyor belt 4, and the pallet stacking mechanism 5 stacks the pallets output from the discharge end of the conveyor belt 4 together. When the pallets are stacked to a certain number, the pallets are forked by a forklift and transported to the designated position, thereby automatically completing the unpacking of the bag without manual unpacking, reducing the labor intensity of the staff, and saving a lot of labor.

[0027] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
