[0033] Reference Figure 1-6 ,
[0034] A powder filling device for preventing powder leakage includes: a storage silo 1, a powder suction pipe 3, a powder suction pump, a support 4, and a support 5. The storage silo 1 has an inlet 11 and a outlet 12, with a packaging bag 6 disposed at the outlet 12; the packaging bag 6 has an opening that aligns with the outlet 12; the powder suction pipe 3 has a powder suction area, intersecting with the bag opening; the support 4 is connected to the storage silo 1, forming a support surface below the outlet 12; the end of the powder suction pipe 3 is located above the support surface; the support 5 is connected to the storage silo 1 and supports the bag body of the packaging bag 6; the powder suction pump is connected to the powder suction pipe 3.
[0035] By adopting the above-mentioned method, the powder is added into the packaging bag 6. However, it is difficult to seal the packaging bag 6 and the discharge port of the discharge hopper, so powder leakage will occur. To address this, a suction pipe and a suction pump are used to suck away the leaked powder, preventing a large amount of powder from entering the air and affecting the air environment. In addition, the support 4 can limit the range of powder diffusion, thus allowing it to be better sucked away by the suction pipe.
[0036] Specifically, a discharge pipe 13 is provided on the storage silo 1, the discharge pipe 13 having a downwardly extending bent section 14, and the discharge port 12 is formed in the bent section 14; the packaging bag 6 is used to fit into the discharge pipe 13. The bent section 14 of the discharge pipe 13 allows the powder to be discharged directly downwards into the packaging bag 6, reducing the amount of powder leakage.
[0037] Specifically, the discharge pipe 13 also has a straight section that connects the bent section 14 to the storage bin 1; the opening of the packaging bag 6 contacts the straight section; the periphery of the discharge pipe 13 is provided with multiple interfaces and a first connecting pipe 2, which connects the interfaces to the powder suction pipe 3. By utilizing the first connecting pipe 2 and the interfaces, the powder overflowing from the opening of the packaging bag 6 can be absorbed over a wider area, better preventing powder leakage.
[0038] Specifically, the support surface has a recessed area to facilitate the containment of powder, thus better accommodating spilled powder.
[0039] Specifically, the storage bin 1 is also equipped with a bag-pressing drive unit 7 and a bag-pressing body 71. The bag-pressing drive unit 7 drives the bag-pressing body 71 to press the packaging bag 6 tightly against the discharge pipe 13. The bag-pressing drive unit is a pneumatic cylinder or a hydraulic cylinder. The bag-pressing body 71 has a block structure. Pressing the packaging bag 6 against the discharge pipe 13 can prevent the packaging bag 6 from falling off.
[0040] Specifically, the support member 5 includes a bracket 51 and a rotating roller 52 rotatably mounted on the bracket 51; the storage bin 1 is also equipped with a bag-pushing drive member 8 and a bag-pushing body 81, the bag-pushing drive member 8 driving the bag-pushing body 81 to move and push the packaging bag 6 away from the storage bin 1; the bag-pushing body 81 has a groove 82 for accommodating the packaging bag 6. Multiple rotating rollers 52 are provided, and these multiple rollers 52 act as a roller conveyor, supporting the packaging bag 6. The outward pushing of the packaging bag 6, in conjunction with the rollers, facilitates the removal of the packaging bag 6. The bag-pushing drive member 8 is a pneumatic or hydraulic cylinder, and the bag-pushing body 81 is a plate.
[0041] Specifically, a receiving hopper 53 is provided below the support member 5, and a second connecting pipe 54 connecting the receiving hopper 53 to the powder suction pipe 3 is also provided in the storage bin 1. This allows for the suction of powder falling downwards.
[0042] Specifically, the storage silo 1 is further equipped with a fixed frame 55, on which a vibrating element is mounted, and a support frame is mounted on the vibrating element. The vibrating element includes a vibration motor 56, a buffer pad 57, and a connecting plate 58; the buffer pad 57 is fixed to the fixed frame 55, and the connecting plate 58 is fixed to the buffer pad 57; the vibration motor 56 is fixedly mounted on the connecting plate 58. By utilizing the vibration motor 56, the packaging bag 6 can be subjected to vibration, allowing the powder in the packaging bag 6 to be better distributed within the packaging bag 6.
[0043] Specifically, a control valve is provided at the feed inlet 11. The feed inlet 11 can be closed in a controllable manner to prevent powder leakage.
[0044] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
