Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding device technology, and in particular to a powder unpacking and feeding device. Background Technology
[0002] In the powder processing industry, raw material supply typically relies on manual unpacking and loading. Operators manually open the discharge ports of powder packaging bags and pour the material into the feeding port or the inlet of the conveyor equipment. However, this method is inefficient and cannot meet the material supply needs of automated production lines, easily becoming a bottleneck restricting production efficiency. Secondly, operators need to frequently perform high-intensity, repetitive actions such as unpacking, handling, and dumping, which not only easily leads to work fatigue but may also cause occupational health problems such as musculoskeletal injuries in the long term. Furthermore, manual unpacking easily generates a large amount of dust, polluting the working environment and harming the respiratory health of workers. Utility Model Content
[0003] The purpose of this invention is to provide a powder unpacking and feeding device to solve one or more technical problems existing in the background art.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] A powder unpacking and feeding device includes a fixed unpacking platform, a bag-pressing ring, a first lifting assembly, a second lifting assembly, a material extraction tank, a material extraction fan, and a hopper. The hopper is located on one side of the fixed unpacking platform. The fixed unpacking platform has a vertically penetrating inlet. The bag-pressing ring and the material extraction tank are both located below the inlet. The first lifting assembly and the second lifting assembly are both located at the bottom of the fixed unpacking platform. The bag-pressing ring is located at the lifting end of the first lifting assembly, and the material extraction tank is located at the lifting end of the second lifting assembly. The input end of the material extraction fan is connected to the material extraction tank, and the output end of the material extraction fan is connected to the hopper.
[0006] Preferably, the outer diameter of the bag-pressing ring is smaller than the inner diameter of the extraction tank.
[0007] Preferably, it also includes a bracket, which is disposed above the feed inlet.
[0008] Preferably, the first lifting assembly includes a plurality of first lifting cylinders, which are evenly arranged at the bottom of the bag-pressing ring, and the telescopic ends of the first lifting cylinders pass through the bag-pressing ring and are connected to the bottom of the fixed unpacking platform.
[0009] Preferably, the second lifting assembly includes a lifting plate and a plurality of second lifting cylinders. The material extraction tank is embedded in the lifting plate, and the plurality of second lifting cylinders are evenly arranged at the bottom of the lifting plate. The telescopic ends of the second lifting cylinders pass through the lifting plate and are connected to the bottom of the fixed unpacking platform.
[0010] Preferably, the top end of the pressure ring is provided with an annular boss, and the outer diameter of the annular boss is smaller than the diameter of the feed inlet.
[0011] Preferably, it also includes an electric hoist, which is located above the fixed unpacking platform.
[0012] The beneficial effects of this utility model are as follows: By setting up a fixed unpacking platform with an inlet, the powder packaging bag can be placed on the platform during unpacking, aligning the discharge port of the bag with the inlet. The discharge port is then fitted onto the inner edge of the bag-pressing ring. A first lifting component drives the bag-pressing ring to press against the fixed unpacking platform, ensuring the edge of the discharge port is tightly against the inlet, guaranteeing the discharge port is fully opened and fixed. After fixing the discharge port, a second lifting component drives the extraction tank to align its opening with the inlet, allowing the powder to fall directly into the extraction tank, achieving sealed extraction and preventing the powder from scattering or clogging during transfer. By connecting the extraction fan to the extraction tank, the powder is extracted into the hopper, completing the unpacking and feeding process. The unpacking and feeding process eliminates the need for manual handling or dumping, significantly reducing labor intensity and improving production efficiency. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the overall structure of one embodiment of the present utility model;
[0015] Figure 2 This is a schematic diagram of the structure of a fixed unpacking platform according to one embodiment of the present invention.
[0016] The components include: a fixed unpacking platform 1, a feeding port 11, a bag pressing ring 2, a first lifting assembly 3, a second lifting assembly 4, a material extraction tank 5, a material extraction fan 6, a hopper 7, a bracket 8, a first lifting cylinder 31, a second lifting cylinder 41, a lifting plate 42, an annular boss 21, and an electric hoist 9. Detailed Implementation
[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] This embodiment provides a powder unpacking and feeding device, see attached drawing. Figure 1 and 2The assembly includes a fixed unpacking platform 1, a bag-pressing ring 2, a first lifting assembly 3, a second lifting assembly 4, a material extraction tank 5, a material extraction fan 6, and a material hopper 7. The material hopper 7 is located on one side of the fixed unpacking platform 1. The fixed unpacking platform 1 has a vertically penetrating inlet 11. The bag-pressing ring 2 and the material extraction tank 5 are both located below the inlet 11. The first lifting assembly 3 and the second lifting assembly 4 are both located at the bottom of the fixed unpacking platform 1. The bag-pressing ring 2 is located at the lifting end of the first lifting assembly 3, and the material extraction tank 5 is located at the lifting end of the second lifting assembly 4. The input end of the material extraction fan 6 is connected to the material extraction tank 5, and the output end of the material extraction fan 6 is connected to the material hopper 7.
[0019] By setting up a fixed unpacking platform 1 with an inlet 11, the powder packaging bag can be placed on the platform during unpacking, aligning the discharge port of the bag with the inlet 11. The discharge port is then fitted onto the inner edge of the pressure ring 2. The first lifting component 3 presses the pressure ring 2 against the platform 1, ensuring the discharge port edge is tightly against the inlet 11, guaranteeing the discharge port is fully opened and fixed. After fixing the discharge port, the second lifting component 4 moves the extraction tank 5 so that its opening aligns with the inlet 11, allowing the powder to fall directly into the extraction tank 5, achieving sealed extraction and preventing the powder from scattering or clogging during transfer. A suction fan 6 connected to the extraction tank 5 draws the powder into the hopper 7, completing the unpacking and feeding process. The unpacking and feeding process eliminates the need for manual handling or dumping, significantly reducing labor intensity and improving production efficiency.
[0020] Preferably, the outer diameter of the bag-pressing ring 2 is smaller than the inner diameter of the extraction tank 5. This ensures that when the opening of the extraction tank 5 aligns with the inlet 11, the bag-pressing ring 2 is located inside the extraction tank 5, guaranteeing that the bag-pressing ring 2 remains fixed to the discharge port of the powder packaging bag during the extraction process, preventing powder from scattering outside the device. During the unloading process, the bag-pressing ring 2 being located inside the extraction tank 5 also ensures sealed extraction, guaranteeing that the powder can be drawn into the hopper 7 by the extraction fan 6, and preventing the generation of large amounts of dust.
[0021] Preferably, the system also includes a bracket 8, which is positioned above the feed inlet 11. The bracket 8 supports the powder packaging bag, ensuring a vertical distance between the bottom of the bag and the feed inlet 11 during unpacking. This provides operational space, allowing operators to easily pass the discharge port through the feed inlet 11 and place it within the inner ring of the bag-pressing ring 2, improving securing efficiency. Furthermore, the bottom of the packaging bag is suspended, allowing the powder to fall naturally and preventing blockages. Combined with the negative pressure suction of the suction tank 5 by the suction fan 6, this ensures complete unloading of the powder.
[0022] Preferably, the first lifting assembly 3 includes a plurality of first lifting cylinders 31, which are evenly arranged at the bottom of the bag-pressing ring 2. The telescopic ends of the first lifting cylinders 31 pass through the bag-pressing ring 2 and are connected to the bottom of the fixed unpacking platform 1. By evenly distributing the plurality of first lifting cylinders 31 at the bottom of the bag-pressing ring 2, the fit between the bag-pressing ring 2 and the fixed unpacking platform 1 is ensured.
[0023] Preferably, the second lifting assembly 4 includes a lifting plate 42 and multiple second lifting cylinders 41. The material extraction tank 5 is embedded in the lifting plate 42, and the multiple second lifting cylinders 41 are evenly arranged at the bottom of the lifting plate 42. The telescopic ends of the second lifting cylinders 41 pass through the lifting plate 42 and are connected to the bottom of the fixed unpacking platform 1. By evenly arranging the multiple second lifting cylinders 41 at the bottom of the lifting plate 42, it is ensured that the force is uniform during the lifting process of the material extraction tank 5, avoiding uneven loading or jamming, improving operational stability, and ensuring precise docking between the extraction port and the unloading port of the packaging bag.
[0024] Preferably, the inner ring of the bag-pressing ring 2 has an annular boss 21 at its top, and the outer diameter of the annular boss 21 is smaller than the diameter of the feed inlet 11. By setting the annular boss 21, the discharge port of the powder packaging bag can be fitted onto the outside of the annular boss 21. When the first lifting component 3 drives the bag-pressing ring 2 to press against the fixed unpacking platform 1, the outer side of the annular boss 21 is in contact with the inner side of the feed inlet 11, and the upper surface of the bag-pressing ring 2 is in contact with the bottom surface of the fixed unpacking platform 1. This achieves multi-point fixation of the discharge port of the powder packaging bag and prevents the discharge port from detaching.
[0025] Preferably, the device also includes an electric hoist 9, which is positioned above the fixed unpacking platform 1. By installing the electric hoist 9, the powder packaging bags can be quickly lifted from the ground to the fixed unpacking platform 1, replacing manual handling, reducing labor intensity, and increasing the loading speed.
[0026] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
