Description

Technical Field

[0001] This utility model relates to the field of powder processing equipment technology, and in particular to a powder unpacking and feeding device. Background Technology

[0002] Powder unpacking is a common step in powder processing. It usually involves opening the bagged powder before processing, removing the powder, and conveying it to the subsequent powder processing system. It is a common work step in modern industry and is usually done manually.

[0003] When using bagged powdered materials, workers need to first use a knife to cut a notch in the packaging bag, then lift the bag and flip it over so that the notch in the packaging bag faces the ground or the mixing drum where the powdered materials are mixed, so that the powdered materials in the packaging bag flow out of the packaging bag through the notch.

[0004] During this operation, workers need to manually cut open the packaging bags and feed the materials. This is labor-intensive and inefficient. In addition, the knives used to cut open the packaging bags are always nearby, which can easily cause cuts or injuries, posing a safety hazard. Therefore, in order to solve the above-mentioned technical problems, this application proposes a powder unpacking and feeding device. Utility Model Content

[0014] For this embodiment, please refer to Figures 1-4 The specific implementation of the powder unpacking and feeding device includes a frame 1, a feeding hopper 2, a loading component and an unpacking component. The feeding hopper 2 is installed in the middle of the frame 1. The loading component is movably arranged above the feeding hopper 2. The unpacking component is fixed above the loading component. The loading component includes a movable seat 3, a swing disk 4 and a servo motor 5. The movable seat 3 is movably inclined above the feeding hopper 2. The swing disk 4 is movably arranged on the bottom surface of the movable seat 3. The top surface of the swing disk 4 is provided with a loading groove 6. The end of the swing disk 4 near the lowest point of the inclined direction of the movable seat 3 is provided with an arrow-shaped guide plate 7. The servo motor 5 is installed at the end of the movable seat 3 away from the guide plate 7. The end of the swing disk 4 away from the guide plate 7 is connected to the output end of the servo motor 5. The unpacking component includes a cutter 8 and a pressing cylinder 9. The cutter 8 is movably arranged above the swing disk 4. The pressing cylinder 9 is arranged above the cutter 8. The swing disk 4 and the movable seat 3 are provided with a clearance opening 10 near the cutter 8. The lower edge of the cutter 8 adopts a barbed structure. Specifically, during operation, the packaging bag will naturally be at the lowest point of the swing plate 4 due to gravity and will be in contact with the guide plate 7 for limitation. At this time, the pressing cylinder 9 is activated. When the pressing cylinder 9 drives the cutter 8 to move towards the packaging bag, the barb on the lower edge of the cutter 8 will first pierce into the packaging bag, opening the opening of the packaging bag while fixing the packaging bag. As the pressure continues, the lower edge of the cutter 8 will contact the edge of the packaging bag, thereby cutting the packaging bag. The powder will flow into the feeding funnel 2 by gravity through the cut opening.

[0015] A mounting platform 11 is connected above the frame 1. A pressing cylinder 9 is fixedly installed on the top surface of the mounting platform 11. The output end of the pressing cylinder 9 passes through the mounting platform 11 and is connected to the top surface of the cutter 8. A waste bag recycling box 12 is provided at the lower end of the frame 1 near the servo motor 5. Anti-fall baffles 13 are inclined on both sides of the top of the waste bag recycling box 12. A clearance position 14 is provided at the end of the mounting platform 11 near the swing plate 4. Specifically, after the powder flows out of the packaging bag, the pressing cylinder 9 drives the cutter 8 to reset, the servo motor 5 starts, and drives the swing plate 4 to flip towards the waste bag recycling bin 12, pouring the cut packaging bag into the waste bag recycling bin 12.

[0016] The top surface of the cutter 8 is provided with guide posts 15 at both ends. The upper end of the guide post 15 extends toward the mounting platform 11. The top surface of the mounting platform 11 is provided with a limiting hole 16 that matches the guide post 15. The frame 1 is equipped with slide rails 17 on both sides near the movable seat 3. The movable seat 3 is fixedly provided with connecting seats 18 on both sides. The bottom surface of the connecting seat 18 slides with the slide rail 17 through the slider 19.

A linkage block 21 is fixedly installed on the side wall of the connecting seat 18. The lower end of the linkage block 21 extends toward the transmission screw 20, and the linkage block 21 is threadedly engaged with the transmission screw 20. A drive motor 22 is provided at one end of the transmission screw 20. The drive motor 22 is fixedly installed on the frame 1, and the rotation shaft of the drive motor 22 is connected to the frame 1. Specifically, the limit range of the movement at both ends of the transmission screw 20 corresponds to the working range of the movable seat 3. When the movable seat 3 moves to the limit distance of the transmission screw 20 near the cutter 8, the clearance opening 10 on the swing plate 4 and the movable seat 3 will correspond to the cutter 8. When the movable seat 3 moves to the end of the transmission screw 20 near the support platform 23, it will facilitate the falling of the packaging bag containing powder on the support platform 23 onto the swing plate 4. The frame 1 is provided with a support platform 23 at the end away from the mounting base. The top edge of the support platform 23 is provided with a U-shaped enclosure 24. The opening of the U-shaped enclosure 24 is set towards the mounting base. The top surface of the support platform 23 is higher than the highest point of the swing plate 4. A push cylinder 25 is provided on the side of the U-shaped enclosure away from the frame 1. A push plate 26 is provided inside the U-shaped enclosure 24 near the push cylinder 25. The push plate 26 is connected to the output end of the push cylinder 25. A screen cover 27 is detachably installed on the upper end of the receiving funnel. Specifically, after transferring the packaging bag to the waste bag recycling bin 12, the drive motor 22 is turned on. The drive motor 22 drives the screw to rotate. At this time, through the cooperation of the linkage block 21 and the screw, the movable seat 3 and the swing plate 4 are moved towards the support platform 23. After moving to the limit area, the staff places the packaging bag containing powder on the support platform 23, turns on the ejection cylinder 25, and ejects the packaging bag, which falls onto the top surface of the swing plate 4.
