[0014] This application provides a quick-assembly and disassembly twin-screw micro-feeding weighing scale, which solves the technical problem that conventional feeders in the prior art are not easy to achieve continuous feeding of small quantities.

[0015] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0016] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0017] A quick-assembly and disassembly twin-screw micro-feeding metering scale, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a feeding component 1 for feeding materials, a weighing platform component 2 for weighing materials, and sanitary clamps 3 for fixing the feeding component 1. The feeding component 1 is mounted on the weighing platform component 2. Two sets of sanitary clamps 3 are installed on the feeding component 1.

[0018] The feeding component 1 includes a top cover 11, a hopper 12, a transmission box cover 13, a stirring gear 14, a transition gear 15, a motor gear 16, an output shaft 17, a transmission box 18, a base 19, a motor mounting cover 20, a planetary reducer 21, a drive motor 22, a screw 23, a stirring blade 24, and a stirring shaft 25. The top cover 11 is mounted on top of the hopper 12. The transmission box 18 is mounted on the base 19. The base 19 is mounted on top of the weighing platform component 2. The transmission box cover 13 is mounted on one side of the transmission box 18. The motor mounting cover 20 is mounted on the other side of the transmission box 18. The planetary reducer 21 is mounted on the motor mounting cover 20. The drive motor 22 is mounted on the planetary reducer 21 and is drive-connected to it. The stirring gear 14, the transition gear 15, the motor gear 16, and the output shaft 17 are all mounted in the transmission box 18, and the motor gear 16 is located at the output end of the planetary reducer 21. The motor gear 16 is meshed with the transition gear 15. Transition gear 15 meshes with stirring gear 14. Motor gear 16 meshes with gear on output shaft 17. Screw 23 is mounted on output shaft 17. Stirring blade 24 is mounted on stirring shaft 25. Stirring shaft 25 is mounted on stirring gear 14. Hopper 12 is fixed to transmission box 18 by sanitary clamp 3. Transmission box 18 is fixed to planetary reducer 21 by sanitary clamp 3. A discharge port is provided at the bottom of hopper 12.

[0019] The weighing platform component 2 includes an upper plate 4, a cover 5, a base plate 6, protective blocks 7, rubber pads 8, sensor pads 9, and a load cell 10. The upper plate 4 is mounted on the cover 5. The cover 5 is mounted on the base plate 6. Four sets of protective blocks 7 arranged in a rectangular array are positioned between the cover 5 and the base plate 6. Four sets of rubber pads 8 arranged in a rectangular array are located at the bottom of the base plate 6. The load cell 10 is installed inside the cover 5. The sensor pad 9 is located at the bottom of the load cell 10 and is attached to the base plate 6.

[0020] The control unit controls the drive motor 22 to supply material to downstream equipment such as extruders, mixers, and reactors at a set flow rate. The drive motor 22 drives the motor gear 16, which in turn drives the output shaft 17 (containing a small gear) to rotate the screw 23, sending the material out of the discharge port 12. At the same time, the motor gear 16 drives the stirring gear 14 and the transition gear 15 to rotate, ensuring that the material does not clump or bridge when it is discharged from the discharge port of the hopper 12 by the stirring blades 7, thus ensuring smooth material conveying. The entire process is a dynamic weighing and metering process. The protective block 7 is used to prevent pressure or tension exceeding the weighing range of the weighing sensor 10 from acting directly on the weighing sensor 10 during transportation. Before transportation, the weighing base plate 6 and the upper plate 4 are directly and rigidly connected with bolts to protect the weighing sensor 10 to the greatest extent. The protective block 7 is removed during metering.

[0021] Thanks to the optimized design of the feeding component 1, weighing platform component 2, and sanitary clamps 3, the equipment allows for quick assembly and disassembly of the feeding component 1 and weighing platform component 2, significantly improving equipment maintenance and replacement efficiency, reducing downtime, and increasing production efficiency. Secondly, the equipment employs a twin-screw design, coupled with a precise motor control system, ensuring uniform material delivery and accurate metering. The minimum precise feeding rate can reach 50 grams per hour, meeting the needs of high-precision micro-feeding and making it suitable for industrial scenarios with extremely high requirements for precise metering of powders or granules. Furthermore, the equipment is equipped with a stirring device to effectively prevent material from clumping and bridging in the hopper, ensuring smooth and continuous material delivery and further improving the stability and reliability of the production process. In terms of structural design, the use of sanitary clamps 3 to fix each component ensures the overall stability of the equipment while facilitating disassembly and cleaning, meeting hygienic production requirements and making it suitable for industries with strict hygiene conditions, such as food and pharmaceuticals. The weighing platform component 3 is equipped with a protective block 7, which effectively prevents pressure or tension exceeding the weighing range of the load cell 10 from directly acting on the sensor during transportation, maximizing the safety of the load cell and extending the service life of the equipment. In summary, this utility model not only improves the accuracy and stability of micro-feeding measurement, but also significantly enhances the ease of operation and applicability of the equipment through its quick assembly / disassembly design and hygienic structural design.
