[0002] In modern manufacturing, powder feeding is a traditional and widely used production method, commonly used in the manufacture of various products. This process typically involves feeding powdered raw materials into a mixing device for uniform mixing. However, traditional automated feeding methods face numerous challenges when processing fine-particle raw materials, especially those with specialized properties such as micron-sized aluminum powder and ammonium perchlorate.

[0003] First, these fine powders are easily affected by air flow and quickly dispersed when entering the mixing kettle, resulting in the waste of raw materials on-site and increasing production costs. Furthermore, since these fine powders can become suspended in the air, escape from the mixing kettle, and deposit on equipment surfaces, they pose a serious safety hazard. During the kneading and mixing process, scattered powders can be squeezed and even generate static electricity, leading to dangerous accidents such as combustion or explosion. This potential danger not only threatens the safety of production equipment but also poses a serious threat to the personal safety of operators.

[0004] Therefore, the traditional powder feeding method has the problem of being unable to effectively control powder dispersion when processing fine powders. New technical solutions are urgently needed to solve the waste of raw materials and safety hazards to ensure the safety and economy of the production process. Utility Model Content

Based on the embodiments provided by the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] The present invention provides a powder feeding device, referring to Figures 1-6As shown, the powder feeding device includes an automatic feeder 1 and a protective mechanism 3; the automatic feeder 1 is connected to the mixing pot 2 for feeding powder into the mixing pot 2; the protective mechanism 3 is arranged between the automatic feeder 1 and the mixing pot 2, one end of which is connected to the discharge port of the automatic feeder 1, and the other end covers the entrance of the mixing pot 2 to prevent the powder from escaping during the feeding process; the protective mechanism 3 is composed of a clamp 301, a universal joint 302, a rubber pad 304 and a connecting piece 303; the clamp 301 is fixed to the discharge port of the automatic feeder 1, the universal joint 302 connects the clamp 301 and the connecting piece 303, and the rubber pad 304 is connected to the universal joint 302 through the connecting piece 303 to cover the entrance of the mixing pot 2; the automatic feeder 1 of the powder feeding device is responsible for feeding the powder into the mixing pot 2 in a quantitative manner; in order to prevent the powder from escaping, a protective mechanism 3 is provided; The protective mechanism 3 is firmly connected to the discharge port of the automatic feeder 1 through the clamp 301, and the rubber pad 304 can be flexibly adjusted through the universal joint 302 to ensure that it can completely cover the entrance of the mixing pot 2 to prevent powder from leaking or polluting the environment during transportation; the function of the universal joint 302 is to provide flexibility so that the angle and position of the rubber pad 304 can be adjusted as needed to adapt to different opening sizes of the mixing pot 2; the device has a simple and practical structure, can effectively prevent powder from escaping during the feeding process, ensure the cleanliness of the production environment and the physical and mental health of the operators; in addition, the design of the universal joint 302 enables the rubber pad 304 to be flexibly adjusted to adapt to mixing pots 2 of different sizes, thereby improving the adaptability and convenience of the device; the structural design of the entire powder feeding device enhances the reliability of operation and reduces the possibility of powder leakage.

[0033] In some embodiments, the rubber pad 304 in the protective mechanism 3 can be replaced with other flexible sealing materials, such as silicone or polyurethane, to meet different environmental requirements. The universal joint 302 can be made of corrosion-resistant materials, such as stainless steel or copper, to adapt to specific working environments. Furthermore, the clamp 301 can be designed with a quick-release design for rapid installation and removal, improving equipment maintenance efficiency.

[0034] Furthermore, the rubber pad 304 can be lowered to the top of the mixing pot 2 when in use, covering the entrance of the mixing pot 2, and can be lifted to a position close to the automatic feeder 1 by the universal joint 302 when not in use. Due to the flexibility of the universal joint 302, the rubber pad 304 can be lowered during use to ensure that it tightly covers the opening of the mixing pot 2 to prevent powder from escaping.

This design ensures the stability of the protective mechanism 3, while enhancing the adjustment capability of the rubber pad 304 in all directions. The distribution of multiple universal joints 302 can better adapt to different openings of the mixing pot 2, and can be adjusted more smoothly and flexibly during operation. The multi-point distribution design of the universal joints 302 allows the rubber pad 304 to cover the opening of the mixing pot 2 more evenly, avoiding the problem of loose sealing caused by improper adjustment of a single universal joint 302. Multiple universal joints 302 also enhance the durability and stability of the device, adapting to various application requirements in different working environments.

[0041] In some embodiments, the number of universal joints 302 can be adjusted based on the size of the automatic feeder 1 and the specific shape of the mixing pot 2.

The second U-shaped clamping groove 3032 is used to insert the rubber pad 304 and securely connect the connecting piece 303 to the rubber pad 304 via the fastener 4. The connecting piece 303 is designed to connect the universal joint 302 and the rubber pad 304 via the first U-shaped clamping groove 3031 and the second U-shaped clamping groove 3032, respectively. The first U-shaped clamping groove 3031 is connected to the universal joint 302, providing stable support for the universal joint 302, ensuring stable operation of the universal joint 302 during adjustment. The second U-shaped clamping groove 3032 is connected to the rubber pad 304, which is securely fastened to the connecting piece 303 via fasteners 4, ensuring that the rubber pad 304 tightly covers the inlet of the mixing pot 2 and prevents powder from escaping. This structure simplifies the installation of the universal joint 302 and the rubber pad 304. The fasteners 4 also enhance the stability of the rubber pad 304, preventing it from falling off or shifting due to vibration or external forces during operation. The design of the first U-shaped clamping groove 3031 and the second U-shaped clamping groove 3032 also enhances the operability of the entire device, making it easier to maintain and clean.

[0043] In some embodiments, both the first U-shaped clamping groove 3031 and the second U-shaped clamping groove 3032 can be adjusted to the different sizes of the universal joint 302 and the rubber pad 304, or designed with different clamping structures, such as V-shaped or parallel grooves, to accommodate different types of materials and structural requirements. Fastener 4 can also adopt a snap-on or knob-type design to improve installation and removal efficiency.

[0044] Furthermore, first through-holes 3033 are provided on each side wall of the first U-shaped clamping groove 3031, and second through-holes 3021 are provided on the universal joint 302. A pin 5 passes through the first and second through-holes 3033 and 3021, rotatably connecting the universal joint 302 to the connecting piece 303, thereby allowing the universal joint 302 to rotate about the pin 5. By providing through-holes in both the first U-shaped clamping groove 3031 and the universal joint 302, the two are connected by the pin 5 passing through the through-holes. This design allows the universal joint 302 to rotate freely about the pin 5, thereby providing flexibility in adjusting the angle of the rubber pad 304. The rotation of the universal joint 302 ensures that the rubber pad 304 can cover openings of mixing pot 2 of varying sizes and shapes, thereby increasing the applicability of the entire device. This design makes the rotational adjustment of the universal joint 302 simple and reliable. The operator can quickly adjust the position of the rubber pad 304 by rotating the universal joint 302, ensuring that it tightly covers the opening of the mixing pot 2 during each use. The pin 5 connection method provides reliable rotation support, improving the durability and operational flexibility of the entire device.

[0045] Furthermore, a plurality of third through holes 3034 are provided on the side walls of the second U-shaped clamping groove 3032. The third through holes 3034 are used to secure the rubber pad 304 via fasteners 4, allowing it to be securely locked or fine-tuned along a predetermined position within the second U-shaped clamping groove 3032, thereby ensuring a reliable seal between the rubber pad 304 and the mixing pot 2. The plurality of through holes are designed on the side walls of the second U-shaped clamping groove 3032. The fasteners 4 securely secure the rubber pad 304 to the connecting piece 303 through these through holes, allowing the rubber pad 304 to be fine-tuned within the second U-shaped clamping groove 3032 as needed. This design ensures that the fixed position of the rubber pad 304 can be adjusted according to the opening size and shape of the mixing pot 2, thereby ensuring close contact and sealing effect with the mixing pot 2; this design allows the position of the rubber pad 304 to be fine-tuned, ensuring that it can form a reliable seal with the inlet of the mixing pot 2 under different conditions, effectively preventing powder from escaping; the use of the fastener 4 ensures the firmness and stability of the rubber pad 304.

[0046] Furthermore, an annular seal is provided between the clamp 301 and the discharge port of the automatic feeder 1; this seal ensures a tight seal at the connection between the clamp 301 and the discharge port of the automatic feeder 1. This seal prevents powder from escaping from the connection between the discharge port and the protective mechanism 3, further improving the sealing performance of the device. The design of the annular seal effectively enhances the sealing performance of the device, preventing powder from escaping from the device connection during the feeding process, thereby improving the safety of the device and the cleanliness of the environment. This design maintains the sealing performance during long-term operation of the device, reducing the risk of powder leakage.

[0047] In some embodiments, the annular seal can be made of different materials, such as high-temperature resistant silicone or fluororubber, to adapt to different working environments. The shape of the seal can also be adjusted according to the structure of the discharge port, such as using a trapezoidal or multi-layer structure to further enhance the sealing effect.

[0048] The working process of the above powder feeding device is as follows:

[0049] The powder feeding device is securely connected to the discharge port of the automatic feeder 1 via a clamp 301.
