[0030] The frame 2 is also provided with a side opening, and a material guide plate 7 is provided on the frame, and the material guide plate 7 is guided into the side opening of the frame 2;

[0031] The bottom of the frame 2 is also provided with an empty bag processing device, such as Figure 4 As shown, the empty bag processing device includes a silo 4 and a bag receiving box 19, the silo 4 is located below the frame 2, a conveyor belt 18 is provided at the opening of the silo 4, a grid is provided on the conveyor belt 18, a baffle is provided between the silo 4 and the bag receiving box 19, an inverted bag pressing cylinder 8 is provided above the bag receiving box 19, a pressing block 21 is provided on the cylinder shaft of the bag pressing cylinder 8, an inner liner 20 is provided in the bag receiving box 19, and a bag receiving box door is provided on the empty bag processing device.

[0032] A placement plate 17 for placing bagged powder is provided at the bottom of the left frame and the bottom of the right frame respectively.

[0033] The left and right sides of the frame are also provided with bag grabbing cylinders 14, such as Figure 3 As shown, the cylinder body of the bag grabbing cylinder 14 is rotatably connected to the frame 2, and the frame 2 is also provided with a swing frame 15, the middle part of the swing frame 15 is hinged to the frame 2, one end of the swing frame 15 is connected to the cylinder shaft of the bag grabbing cylinder 14, the other end of the swing frame 15 is provided with a lower grabbing hook, and the placement plate of the frame is provided with a grabbing hook hole 24. The swing frame 15 is constructed as a rocking block mechanism. When pouring, the cylinder shaft of the bag grabbing cylinder 14 extends, so that the lower grabbing hook moves upward, so that the bag is hooked, the powder can fall under the action of gravity, but the bag cannot. After the pouring process is completed, the cylinder shaft of the bag grabbing cylinder 14 is retracted, the grabbing hook moves downward, the powder bag is released, and the empty bag falls.

[0034] Swing frames 15 are respectively provided on both sides of the bag grabbing cylinder 14 , and a swing frame push rod 16 is connected to the cylinder shaft of the bag grabbing cylinder 14 , and both ends of the swing frame push rod 16 are respectively connected to the swing frame 15 .

[0035] In this embodiment, Figure 3 As shown, the hanger of the frame 2 includes an upper crossbeam, a lower hanger plate 12 and two side hangers 10, the upper crossbeam is fixedly connected to the frame, the side hangers 10 are provided with hinge seats, the left connecting rod 13 and the right connecting rod 22 are respectively hinged on the hinge seats of the side hangers 10, the push plate 9 is located between the two side hangers 10, the lower hanger plate 12 is provided with a sliding hole, and the push rod 11 passes through the sliding hole.

[0036] In this embodiment, Figure 2 As shown, rollers are provided on the guide plate 7. The guide plate is set at a certain angle so that the material bag can fall into the frame 2 under the action of gravity. In order to reduce friction and ensure that the material bag slides down, rollers are designed on the guide plate to effectively reduce friction.

[0037] The working principle of this embodiment is as follows: This device uses pneumatic as the main power source, adopts PLC to control the movement of the cylinder, and realizes various actions through the cylinder, realizing various processes such as bag opening, material pouring, and empty bag processing, and ensuring that the material pouring is clean. Bag opening and material pouring action process: the bagged powder uses gravity and inertia to fall into the frame 2 through the material guide plate 7, driving the bag grabbing cylinder 14, and the lower grabbing hook passes through the grabbing hook hole 24 and extends into the frame 2 to hook the material bag. At the same time, the bottom knife cylinder 3 drives the bottom knife to cut the bottom of the bag. After the bottom knife returns to its position, the side knife cylinder 6 moves the side knives on both sides downward to cut the two sides of the packaging bag. After returning to its position, the pouring cylinder 5 is driven, and the push rod 11 pushes the hinge between the left frame and the right frame downward, so that the left frame and the right frame are opened, and the powder falls from between the left frame and the right frame. After the pouring cylinder 5 moves up and down several times, it is ensured that the material is poured cleanly, and the grabbing hook is released, and the empty bag automatically falls on the empty bag processing device.

[0038] The empty bag falls on the conveyor belt of the empty bag processing device. The conveyor belt 18 is provided with a grid to ensure that the powder falls into the silo 4, while the empty bag is on the conveyor belt 18. As the conveyor belt 18 conveys, the powder packaging bag falls into the bag receiving box 19. The silo 4 and the bag receiving box 19 are designed as a whole to ensure that the powder does not fall outside the silo 4 and cause pollution. The silo 4 and the bag receiving box 19 are separated by a baffle, and the upper end of the baffle is at a 45° angle to ensure that the powder remaining on the conveyor belt 18 can slide along the baffle to the silo 4.

[0039] Open the door of the bag collecting box 19 to take out the empty bags. Considering that there is still a lot of dust on the empty bags, which pollutes the workshop and affects the health of workers, an inner liner 20 is set, which can be covered with a disposable garbage bag to directly pack the powder bags. Considering that the powder packaging bags are in a messy state, a photoelectric switch can be installed on the top of the inner liner. When the photoelectric switch senses that the powder bags have accumulated to a certain height, the PLC moves the bag pressing cylinder 8, so that the pressing block 21 compacts the powder bags. When the powder bags accumulate to a certain number, the side bag collecting box door can be opened to take them out, which can reduce the dust to a certain extent.

[0040] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
