[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figure 1 As shown in Figure 5, this embodiment provides a dustproof loss-in-weight screw continuous weighing scale for a powder production line, including a device body 1. The device body 1 includes a weighing platform 2, a support frame 3 above the weighing platform 2, a conveying cylinder 5 on the support frame 3, a screw rod 6 inside the conveying cylinder 5, and a feeding hopper 7 connected to the conveying cylinder 5. One end of the screw rod 6 is connected to a motor 4. The feeding hopper 7 contains a motor 11 and a mounting plate 9. A stirring blade 12 is connected below the motor 11. A dispersing leaf 13 is connected to a mounting plate 9, and a metering hopper 14 is connected to the mounting plate 9. The metering hopper 14 is equipped with a maintenance cover 15, a feeding port 17 and an exhaust pipe 18 on the maintenance cover 15. A filter screen 19 is installed inside the exhaust pipe 18. A filter screen 24 is installed below the filter screen 19, and a connecting rod 25 is installed below the filter screen 19. A connecting rod 26 is installed on the filter screen 24. L-shaped clamps 20 are connected to both ends of the filter screen 19. A screw hole 22 is provided inside the L-shaped clamp 20, and a bolt 23 is screwed into the screw hole 22.
[0026] Preferably, the weighing platform 2 is provided with foot pads 29 below it. Multiple foot pads 29 are fixedly installed. By setting foot pads 29, the stability of the weighing platform 2 is increased, ensuring the safety of the weighing platform 2 during use and preventing the weighing platform 2 from sliding during use. The mounting plate 9 is fixedly provided with a mounting bracket 10, and a motor 2 11 is fixedly installed on the mounting bracket 10. By setting the mounting bracket 10, the stability of the motor 2 11 is increased, ensuring the safety of the motor 2 11 during use. One end of the conveying cylinder 5 is connected to a discharge pipe 8, which is fixedly connected to the conveying cylinder 5. By setting the discharge pipe 8, it is convenient to discharge the material in the conveying cylinder 5, increasing the practicality and convenience of the device.
[0027] Preferably, the exhaust pipe 18 has a slot 21, in which an L-shaped locking rod 20 is movably installed. By setting the slot 21, the L-shaped locking rod 20 can be positioned, making it convenient for users to install and fix the device, thus improving the flexibility and convenience of the device. Both the second filter screen 24 and the first filter screen 19 have multiple sets of filter holes. The filter holes of the second filter screen 24 are larger than the filter hole diameter of the first filter screen 19, which can filter the dust in the device multiple times, improving the safety of the device and ensuring the health of the staff. The connecting rod 25 and the second connecting rod 26 are screwed with nuts 27. The nuts 27 have anti-slip grooves 28. By setting the nuts 27, the device can be fixed. By setting the anti-slip grooves 28, users can avoid slipping their hands or difficulty in tightening the nuts 27 during the pre-tightening adjustment process.
[0028] The working principle and process of this utility model are as follows: In use, the material first enters the metering hopper 14, then flows through the metering hopper 14 into the feeding hopper 7. The material in the feeding hopper 7 then enters the conveying cylinder 5. Driven by motor 4, based on the weight change measured by the weighing sensor, the screw 6 is driven to convey the material. When it is necessary to disperse the material entering the feeding hopper 7, motor 11 is controlled to operate. Motor 11 drives the stirring blade 12 to rotate, which in turn drives the dispersing blade 13 to rotate. The rotation of the stirring blade 12 and the dispersing blade 13 stirs and disperses the material in the feeding hopper 7 until the material safely enters the conveying cylinder 5. This process disperses and stirs the material entering the device, improving material flowability, preventing agglomeration and bridging, ensuring material uniformity, improving metering accuracy, optimizing feeding stability, and reducing equipment failures. The screw motor speed is adjusted to achieve… Precise quantitative feeding prevents material accumulation. When dust filtration is required during use, the user places the nut 27 onto the connecting rod 25, then aligns the connecting rod 26 of filter screen 24 with the connecting rod 25 of filter screen 19. The user then manually rotates the nut 27 to connect and fix the connecting rod 25 and connecting rod 26. The filter screen 19 with the L-shaped locking rod 20 is then placed inside the exhaust pipe 18, and the L-shaped locking rod 20 is engaged with the slot 21. The bolts 23 are then screwed into the bolt holes 22 for fixation. Dust is discharged after being filtered by filter screen 24 and filter screen 19, enabling secondary filtration and discharge of dust generated during material transport, improving dust interception efficiency, enhancing dust prevention, ensuring the health of workers, and facilitating future filter maintenance.
