Description

Technical Field

[0001] This utility model belongs to the field of automatic powder feeding technology, specifically relating to an automatic powder feeding device. Background Technology

[0002] Automated feeding of powders (such as chemical raw materials, food additives, and pharmaceutical intermediates) is a crucial step in industrial production. Traditional manual feeding relies on operator experience, with single-batch errors reaching ±5%, leading to fluctuations in product quality. While mechanical feeding equipment (such as screw conveyors) can improve efficiency, it lacks dynamic adjustment capabilities and struggles to adapt to the flexible production demands of diverse products in small batches. The dust generated during powder feeding not only pollutes the environment but also wastes raw materials, reducing overall production efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an automatic powder feeding device. The powder bag is conveyed to the feeding port of the feeding chamber through a transmission mechanism, and the powder bag is automatically cut open by an automatic bag-cutting mechanism, allowing the powder to automatically enter the material silo. The dust generated during the process is recycled by a powder recovery mechanism, thereby solving the problem that the dust generated during the powder feeding process not only pollutes the environment but also wastes raw materials and reduces overall production efficiency.

[0017] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0018] Combination Figure 1 and Figure 2 As shown, an automatic powder feeding device includes a feeding chamber 1, a conveying mechanism 2 for transporting material bags is provided inside the feeding chamber 1, a feeding port 3 is provided inside the feeding chamber 1, the feeding port 3 is connected to a conveying pipe 4, the conveying pipe 4 is connected to a material bin 5, an automatic bag-cutting mechanism 6 for cutting open the material bags is provided inside the feeding port 3, a vibration mechanism 7 is provided below the automatic bag-cutting mechanism 6, and a powder recovery mechanism 8 is provided inside the feeding chamber 1.

[0019] This invention discloses an automatic powder feeding device. The feeding chamber 1 provides a closed or semi-closed space for powder feeding operations. A conveying mechanism 2, located inside the feeding chamber 1, transports powder bags. A feeding port 3, an opening inside the feeding chamber 1, is used to feed the powder from the powder bags into a subsequent conveying pipe 4. The conveying pipe 4 connects the feeding port 3 and a material hopper 5, transporting the split powder from the feeding port 3 to the material hopper 5. The material hopper 5 stores the powder transported from the feeding port 3 through the conveying pipe 4. The material hopper 5 has metering, mixing, or other processing functions to meet the needs of subsequent production or processing.

[0020] The automatic bag-cutting mechanism 6 is located inside the feeding port 3 and is used to automatically cut open the bag, allowing the powder to flow out smoothly. The vibration mechanism 7 is located below the automatic bag-cutting mechanism 6 and is used to help the powder flow completely out of the bag after cutting, and to reduce powder residue in the feeding port 3 or the transmission pipe 4. The powder recovery mechanism 8 is located inside the feeding chamber 1 and is used to recover powder that may be scattered during the feeding process, ensuring that the scattered powder can be effectively recovered and reused.

[0021] The conveying mechanism 2 transports the powder-filled bag to a designated location within the feeding chamber 1, near the feeding port 3. When the bag reaches the feeding port 3, the automatic bag-cutting mechanism 6 begins operation, cutting open the bag to allow the powder to flow out. The cut powder flows through the feeding port 3 into the conveying pipe 4 and is then transported to the material hopper 5. During the powder outflow process, the vibration mechanism 7 operates, using vibration to help the powder flow completely out of the bag and reduce residue. If any powder spills during the feeding process, the powder recycling mechanism 8 collects it, ensuring a clean working environment and powder reuse.

[0022] Combination Figure 1 and Figure 2 As shown, the automatic packaging mechanism 6 includes a blade 61 disposed inside the feeding port 3, and the blade 61 has a drive mechanism for reciprocating movement.

[0023] Specifically, the blade 61 is located inside the feeding port 3. The blade 61 effectively cuts through the material bag while ensuring stability and safety during the cutting process. The blade 61 has a sharp cutting edge to easily cut into the surface of the material bag. A drive mechanism is connected to the blade 61 and is responsible for driving the blade 61 to reciprocate. Power is transmitted to the blade 61 through a transmission device, enabling it to reciprocate along a predetermined trajectory and speed.

[0024] refer to Figure 1 As shown, the powder recycling mechanism 8 includes a grid opening 81 installed inside the feeding chamber 1. The grid opening 81 is connected to a recycling pipe 82, which is connected to the material silo 5.

[0025] Specifically, the grating opening 81 is located inside the feeding chamber 1, near the feeding port 3, or in a position where powder is likely to scatter during the feeding process. The grating opening 81 consists of a series of parallel or intersecting grating bars, forming a mesh structure that allows scattered powder to pass through while preventing larger debris or fragments of the material package from entering the recycling system. The recycling pipe 82 is connected to the grating opening 81 and is responsible for transporting the powder passing through the grating opening 81 to subsequent processing or storage locations. The other end of the recycling pipe 82 is connected to the material silo 5, allowing the recycled powder to directly enter the material silo 5 for reuse.

[0026] During the feeding process, some powder may spill into the feeding chamber 1. Under the influence of gravity or airflow, the spilled powder passes through the mesh structure of the grille 81 and enters the recycling pipe 82. The mesh structure of the grille 81 effectively prevents larger debris or fragments of the material bag from entering the recycling system, ensuring the purity of the recycled powder. The powder entering the recycling pipe 82 flows within the pipe and is conveyed to a location connected to the material silo 5. During the conveying process, the smooth inner wall and suitable slope of the pipe reduce powder residue and blockage, ensuring recycling efficiency. The recycled powder enters the material silo 5 through a connection, where it is mixed with newly added powder or stored separately, awaiting subsequent production or processing. Through the powder recycling mechanism 8, the effective recycling and reuse of spilled powder is achieved, reducing waste and environmental pollution.

[0027] refer to Figure 1 As shown, the transmission mechanism 2 includes a crane 21 installed at the top of the inside of the feeding chamber 1. A horizontal plate 22 is connected to the lifting ring of the crane 21, and hooks 23 are connected to both ends of the horizontal plate 22.

[0028] Specifically, the overhead crane 21 is located at the top inside the feeding chamber 1 and is a lifting device capable of moving along a specific track or direction. It can transport material bags to a designated location. A lifting ring is connected below the overhead crane 21, serving as the suspension point for the horizontal plate 22. The horizontal plate 22 is horizontally connected to the lifting ring of the overhead crane 21, serving as a support platform for the hooks 23. The length and width of the horizontal plate 22 are designed according to actual needs to allow for the simultaneous connection of multiple hooks 23. The hooks 23 are connected to both ends of the horizontal plate 22 for suspending and securing the material bags. The design of the hooks 23 should ensure a secure grip on the material bags, preventing them from falling off during transportation.

[0029] Combination Figure 1 and Figure 2 As shown, the vibration mechanism 7 includes a first vibrating plate 71 disposed inside the feeding port 3, and the first vibrating plate 71 is connected to a drive motor 72.

[0030] Specifically, the first vibratory feeder 71 is located inside the feeding port 3, ensuring a good match with the internal structure of the feeding port 3 and maximizing the vibration effect. The drive motor 72 is the power source for the vibration mechanism 7 and is connected to the first vibratory feeder 71.

[0031] When vibration-assisted feeding is required, the drive motor 72 is started. The drive motor 72 begins to rotate, generating mechanical energy. The mechanical energy generated by the drive motor 72 is transmitted to the first vibratory plate 71. After receiving the energy, the vibratory plate begins to vibrate according to the set frequency and amplitude. The vibration of the first vibratory plate 71 causes the powder inside the feeding port 3 to be subjected to periodic impact force. This impact force helps the powder to flow completely out of the material bag, reducing residue and promoting the uniform distribution of powder inside the feeding port 3. At the same time, vibration can also prevent the powder from forming blockages or clumps inside the feeding port 3, improving the smoothness and efficiency of feeding.

[0032] When feeding is complete or vibration assistance is no longer needed, the drive motor 72 stops operating. The first vibratory feeder 71 gradually stops vibrating and returns to a stationary state, awaiting the start of the next feeding operation.

[0033] Combination Figure 1 and Figure 2 As shown, a patting port 31 for patting the material bag is provided on one side of the feeding port 3, and a second vibrating plate 32 is provided inside the patting port 31.

[0034] Specifically, the bag-tapping opening 31 is located on one side of the feeding port 3, typically positioned before the bag enters the feeding port 3, facilitating pre-treatment of the bag. Mechanical tapping or vibration loosens and disperses the powder within the bag, preventing clumping or residue and ensuring smooth feeding. The open design allows the bag to partially or completely enter the tapping area. A second vibrating plate 32 is installed inside the bag-tapping opening 31, acting directly on the bag.

[0035] Combination Figure 1 and Figure 2 As shown, both the feeding port 3 and the bagging port 31 adopt a funnel-shaped structure.

[0036] Specifically, the feeding port 3 is designed as a funnel shape, wider at the top and narrower at the bottom. The larger opening at the top receives material bags or powder, while the gradually narrowing bottom forms the discharge port, connecting with subsequent conveying pipes or equipment. The bag-tapping port 31 also adopts a funnel shape, but its top opening may be larger to accommodate material bags entering the tapping area. Its bottom connects with the feeding port 3 or the second vibrating plate 32. Through this funnel-shaped structure, the feeding port 3 and the bag-tapping port 31 achieve efficient, stable, and low-residue operation during powder processing, becoming a key design feature of the automated feeding system.

[0037] refer to Figure 1 As shown, the feeding chamber 1 is equipped with a pneumatic door 9.

[0038] Specifically, the pneumatic door 9 is located at the entrance / exit of the feeding chamber 1 (such as the material bag inlet, personnel access door) or at a key partition. The operator presses the start button, or the system automatically detects that feeding preparation is complete (such as material bag positioning completion, dust collector startup). When the pneumatic door 9 is not closed, equipment such as the dust collector and vibratory feeder in the feeding chamber 1 cannot start, preventing dust spillage. With the door open, the system automatically cuts off the power to downstream equipment (such as the mixer) to prevent accidental operation. Through the precise control of the pneumatic door 9, the feeding chamber 1 achieves safe, efficient, and low-pollution material handling, becoming an indispensable isolation and passage device in automated production lines.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
