[0002] In industrial production, powder feeding operations are very common. Many industrial fields require the use of powdering equipment to evenly spread powder on specific products or work surfaces. However, traditional powdering equipment has many drawbacks:

[0003] Inaccurate powder spreading: Traditional powder spreading methods are mostly manual operations, which makes it difficult to ensure the accuracy and uniformity of the powder amount, which greatly affects the quality and appearance of the final product. Manual powder spreading is inefficient and requires workers to exert a lot of physical labor, which can easily lead to fatigue.

[0004] Low degree of automation: Most existing powder spreading equipment is semi-automated or completely dependent on manual operation, lacks intelligent control, and cannot meet the high efficiency requirements of modern production.

[0034] In this embodiment, as a preferred technical solution, the switch assembly includes an electric push rod 10 fixedly arranged on the outer wall of the auger conveying mechanism 4, and also includes a flip cover 11 hingedly arranged at the outlet of the auger conveying mechanism 4, and the piston end of the electric push rod 10 is hinged to the flip cover 11.

[0035] In this embodiment, as a preferred technical solution, the weighing component 12 adopts an electronic weighing scale, and the powder sprinkling head 8 is fixedly arranged on the upper end of the electronic weighing scale.

[0036] In this embodiment, as a preferred technical solution, the stirring mechanism includes a stirring shaft 13 rotatably arranged inside the powder storage tank 3, a stirring arm 14 is fixedly provided on the stirring shaft 13, the auger conveying mechanism 4 includes a feeding barrel 15 and an auger rotatably arranged inside the feeding barrel 15, the power mechanism includes a motor 16 fixedly arranged inside the motor box 2, the driving shaft of the motor 16 is drivingly connected to the stirring shaft 13 and a sprocket 17 is fixedly provided on the driving shaft, a sprocket 2 18 is fixedly provided at the shaft end of the auger, and the sprocket 17 and the sprocket 2 18 are connected by a chain.

[0037] A quantitative feeding device also includes an automatic control system, which uses a PLC controller. The motor 16, electric push rod 9, electric push rod 2 10, stepper motor 7, and weighing component 12 are all electrically connected to the PLC controller to achieve programmed control.

[0038] The working principle of this quantitative feeding device is as follows: the device primarily uses a motor 16 to drive a stirring mechanism to stir the powder in the powder storage tank 3 to prevent the powder from clumping. The auger conveying mechanism 4 then conveys the powder to the dusting head 8, with a switch assembly preventing leakage. A weighing assembly 12 monitors the powder weight data. The feed rod 6, driven by a stepper motor 7, performs linear motion, moving the weighing assembly 12 and dusting head 8 to a designated position for dusting. The electric push rod 9 drives the weighing assembly 12 to flip downward for unloading. The entire process, through the coordinated operation of various components, achieves precise quantitative feeding of the powder.

[0039] The use process of the quantitative feeding device of the utility model is as follows:

[0040] 1. Preparation: Add powder into the powder storage tank 3, turn on the power, start the equipment, and the motor 16 in the motor box 2 starts running.

[0041] 2. Mixing and conveying: The driving shaft of the motor 16 drives the stirring shaft 13 to rotate. The stirring arm 14 on the stirring shaft 13 stirs the powder in the powder storage tank 3 to prevent the powder from agglomerating and maintain the uniformity of the powder. The sprocket 17 on the driving shaft of the motor 16 drives the sprocket 2 18 to rotate through a chain (not shown in the figure), thereby causing the auger to rotate in the feeding barrel 15, and conveying the powder from the bottom of the powder storage tank 3 to the outlet of the auger conveying mechanism 4, and then falling into the powder sprinkling head 8.

[0042] 3. Weighing: The powder flows out of the outlet of the auger conveyor mechanism 4 and falls into the powdering head 8. The weighing component 12 uses an electronic scale to monitor the weight of the powder. When the set weight is reached, the switch component of the auger conveyor mechanism 4 is closed, and the material is stopped from being discharged.

[0043] 4. Prevent powder leakage: After the powdering head 8 is loaded with powder, it is necessary to temporarily block the outlet of the auger conveying mechanism 4. At this time, the electric push rod 2 10 on the outer wall of the auger conveying mechanism 4 is controlled to extend, and the piston end of the electric push rod 2 10 pushes the flip cover 11 to cover the outlet, thereby preventing the powder from flowing out of the outlet of the auger conveying mechanism 4.

[0044] 5. Feeding: The stepper motor 7 drives the feeding rod 6 to move linearly in the sliding track 5, and moves the weighing assembly 12 hinged at the outer end of the feeding rod 6 and the powder sprinkling head 8 at the upper end to the position where powder needs to be sprinkled.

[0045] 6. Powdering operation: The electric push rod 9 extends, and the piston end of the electric push rod 9 is hinged on the weighing assembly 12, driving the weighing assembly 12 to flip downward, and the powder is sprinkled from the powdering head 8. After the powdering is completed, the electric push rod 9 retracts, and the weighing assembly 12 returns to its initial position, preparing for the next weighing and powdering operation.

[0046] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
