Description

Technical Field

[0001] The utility model relates to the field of filling equipment, in particular to a high-efficiency and non-difficult-to-classify powder filling device. Background Art

[0002] In the powder processing and packaging industry, the filling process of mixed powder is a crucial link. Traditionally, many companies use gravity vertical filling devices to fill mixed powders, which faces many challenges in practical applications. Due to the differences in density and particle size of each material in the mixed powder, when the material is filled in the vertical falling process, the material classification phenomenon often occurs.

[0003] In order to overcome these defects of gravity vertical filling devices, twin-screw powder filling methods have gradually attracted attention in recent years. Twin-screw powder filling devices force powder into packaging containers through two intermeshing screws, thereby avoiding the problem of material classification to a certain extent. The efficiency of twin-screw powder filling devices is relatively low and cannot meet the needs of mass production. Due to the rotation and friction of the screws, the device is prone to heat during operation, and temperature-sensitive powders may deteriorate, affecting product quality.

[0004] The existing powder filling device needs to be discharged from the lower hopper and sent to the packaging can after being conveyed by the barrel. However, the sizes of the packaging cans in different production batches are different, and the discharge position of the lower hopper is relatively fixed. The discharge position cannot be adjusted according to the different sizes of packaging cans. The fixed discharge position may also cause the grading of the powder during the filling process to be aggravated. If the discharge position cannot be accurately aligned with the mouth of the packaging can, the powder may be unevenly dispersed due to impact when entering the can, forming stratification, which not only affects the uniformity and stability of the product, but may also have an adverse effect on the subsequent production process.

[0025] Refer to Figures 1 - 5, A high-efficiency powder filling device that is not easily classified, comprising: a material cylinder 2 for conveying powder, serving as the main conveying channel for the powder. The design of the material cylinder 2 ensures the smooth flow of the powder; a feeding hopper 5 is provided at one end of the material cylinder 2 for powder feeding. The feeding hopper 5 is directly connected to the material cylinder 2 and is a key component for the powder to enter the filling container from the material cylinder 2. Its design enables the powder to accurately and stably fall into the filling container, reducing waste and pollution. The adjustability of the feeding hopper 5 allows users to adjust the feeding position according to different filling requirements, improving the flexibility and adaptability of the equipment; an adjusting plate 6 is installed on the material cylinder 2. The feeding hopper 5 is connected to the adjusting plate 6. The adjusting plate 6 is arranged to move on the material cylinder 2 for adjusting the position of the feeding hopper 5 on the material cylinder 2; the projected shape of the adjusting plate 6 is arc-shaped. The design of the adjusting plate 6 allows users to easily adjust the position of the feeding hopper 5 on the material cylinder 2 without a complex disassembly and reinstallation process. Its arc-shaped projected shape provides a smooth sliding path, reducing the resistance and friction during adjustment. Through the fixing action of the second fastening knob 602, users can ensure the stability of the adjusting plate 6 at the selected position and prevent accidental movement during the filling process; a fixing plate 601 is installed on the adjusting plate 6. The feeding hopper 5 is arranged to move on the fixing plate 601 for adjusting the feeding position of the feeding hopper 5. The fixing plate 601 serves as the support and adjustment platform for the feeding hopper 5. Its design ensures the stability and accuracy of the feeding hopper 5 during movement. By cooperating with the first fastening knob 501, users can precisely control the horizontal and vertical positions of the feeding hopper 5 to adapt to filling containers of different sizes and shapes.

[0026] Refer to Figure 3 , Figure 4 and Figure 5 , The adjusting plate 6 includes: a second fastening knob 602 installed on the adjusting plate 6. The material cylinder 2 is connected to the second fastening knob 602. The second fastening knob 602 is arranged to rotate on the adjusting plate 6 for fixing the position of the adjusting plate 6 on the material cylinder 2.

[0027] Refer to Figure 3 and Figure 4 , The feeding hopper 5 includes: a first fastening knob 501 installed on the feeding hopper 5. The first fastening knob 501 is connected to the fixing plate 601. The first fastening knob 501 is arranged to rotate on the feeding hopper 5 for fixing the position of the feeding hopper 5 on the fixing plate 601; a recess 502 is opened on the feeding hopper 5. The material cylinder 2 is arranged at the recess 502.

[0028] The first fastening knob 501 and the second fastening knob 602 are respectively used to fix the position of the blanking hopper 5 on the fixing plate 601 and adjust the position of the adjusting plate 6 on the barrel 2, making the adjustment process of the entire filling device simple and fast without the need to use additional tools or equipment. The reliability of the fastening knobs ensures the stability of each component during the filling process, preventing problems such as powder leakage or inaccurate filling caused by loosening.

[0029] The barrel 2 includes: a feeding screw 201, connected inside the barrel 2, for driving the powder to move inside the barrel 2 when rotating; since the mixed powder uses a horizontal single-screw blanking, the diameter of the feeding screw 201 can reach 100 mm, with high conveying efficiency, little heat generation, and little impact on temperature-sensitive powder.

[0030] Refer to Figure 2 and Figure 3 , the mounting frame 1, the barrel 2 is mounted on the mounting frame 1; the power source 3, mounted on the mounting frame 1, the power shaft of the power source 3 is connected to one end of the feeding screw 201, for providing rotational power for the feeding screw 201; the air lock 4, mounted on the mounting frame 1, the air lock 4 is connected to the barrel 2, the power source 3 is connected to the air lock 4, ensuring uniform and stable blanking from the source; the storage bin 401, mounted on the air lock 4, for storing powder, the power source 3 uses a servo motor or a stepper motor can also be used.

[0031] During use, the powder material is imported from an external source into the storage bin 401. The storage bin 401 serves as a storage container for the powder material to ensure that there is sufficient powder material for subsequent filling. According to the size and shape of the container to be filled, the position of the hopper 5 is adjusted. By rotating the first fastening knob 501 counterclockwise, the fixing restriction of the hopper 5 on the fixing plate 601 can be cancelled, and the position of the hopper 5 can be accurately controlled on the fixing plate 601 to ensure that the powder material can accurately fall into the filling container. After rotating the first fastening knob 501 clockwise, the position of the hopper 5 on the fixing plate 601 can be fixed again. Similarly, by rotating the second fastening knob 602, the fixing restriction of the adjusting plate 6 on the barrel 2 can be cancelled, and the adjusting plate 6 can be moved on the barrel 2 to adjust the overall position of the hopper 5 on the barrel 2 to adapt to different filling requirements. After rotating the second fastening knob 602 in the reverse direction, the position of the adjusting plate 6 on the barrel 2 can be fixed. The power source 3 is started, and the power source 3 provides rotational power for the feeding screw 201. The feeding screw 201 rotates inside the barrel 2 to drive the powder material to move inside the barrel 2. Since the diameter of the feeding screw 201 is relatively large, it can efficiently convey the powder material and generate less heat, having less impact on temperature-sensitive powder materials. The air lock 4 starts to work, which is connected to the barrel 2 to control the flow rate and speed of the powder material and prevent the powder material from splashing or leaking due to air pressure changes. Driven by the feeding screw 201, the powder material passes through the barrel 2 and enters the hopper 5. The hopper 5 accurately and stably drops the powder material into the filling container according to the preset position and angle. According to the capacity and filling requirements of the filling container, the filling operation is continuously carried out until the required filling amount is reached.

[0032] In summary, compared with the prior art, the following beneficial effects are achieved:

[0033] Through the design of the adjusting plate 6 and the fixing plate 601, the discharging position of the hopper 5 can be flexibly adjusted according to different sizes of packaging cans, improving the flexibility and adaptability of the equipment and meeting the needs of diversified production batches.

[0034] By precisely adjusting the position of the hopper 5 to ensure its accurate alignment with the mouth of the packaging can, the risk of uneven dispersion of the powder material due to impact during filling is reduced, which helps to reduce the classification phenomenon of the powder material, improve the uniformity and stability of the product, and enhance the overall quality of the product.

[0035] The flexible adjustment of the position of the hopper 5 makes the filling process smoother, reducing the time wasted due to adjusting the position of the packaging can or the angle of the hopper 5. The accurate alignment reduces the waste and pollution of the powder material, improving the filling efficiency and accuracy.
