Technical Field

[0001] The invention relates to the technical field of quantitative powder spraying devices, in particular to a flow aid quantitative powder spraying device. Background Art

[0002] Flow aids are a type of additive added to powdered or granular materials to improve the fluidity and handling characteristics of these materials. They are widely used in a variety of industries such as food, pharmaceuticals, chemicals, plastics, and cosmetics to ensure a smooth production process and improve product quality. However, flow aid powder spraying devices in the prior art usually use manual weighing to achieve quantitative purposes, and are unable to achieve random and automatic quantitative addition of flow aids, resulting in unstable product quality and failure to meet industry standards and regulatory requirements, increasing batch differences, affecting product performance and user experience, and resulting in decreased customer satisfaction and weakened market competitiveness. Furthermore, during the discharging process of the flow aid powder spraying device, if the material inside the tank containing the flow aid agglomerates or flows unevenly due to static electricity, the flow aid will have poor fluidity during discharging, greatly affecting the discharging efficiency of the flow aid.

When the quantitative flow aid powder flows into the quantitative hole, the rotary cylinder is started to drive the rotating shaft to rotate ninety degrees, and then the quantitative flow aid powder is sprayed out by starting the air compressor, thereby reducing the risk of inaccurate manual weighing, realizing random and automatic quantitative addition of flow aid, ensuring the stability of product quality, meeting industry standards and regulatory requirements, avoiding differences between product batches, improving product performance and user experience, and thereby improving customer satisfaction and market competitiveness.

At the same time, the circumferentially distributed flow guide plates 606 guide the material to concentrate toward the center, avoiding the retention of the material on the warehouse wall, promoting continuous and stable flow, avoiding uneven flow of the flow aid powder, and improving the discharge efficiency of the flow aid powder. Even under high flow or long-term operation, the flow aid powder can maintain good fluidity, which greatly improves the reliability and work efficiency of the entire device.

[0024] The working principle of the flow guiding mechanism 6 is as follows: the operator places the flow guiding mechanism 6 into the flow aid storage bin 1, and at the same time moves the locking rod 604 toward the inside of the fixing frame 601, so that the two groups of locking balls 603 inside the fixing frame 601 are moved away from each other, and with the cooperation of the spring 602, the locking balls 603 are locked into the locking groove 6041, so that the flow guiding mechanism 6 can be firmly placed in the flow aid storage bin 1. When the flow guiding mechanism 6 needs to be removed, the flow guiding mechanism 6 is moved upward, so that the two groups of locking balls 603 are again moved away from each other under the squeezing action of the locking rod 604, so that the locking balls 603 are no longer locked into the locking groove 6041, and then the flow guiding mechanism 6 can be removed, which is convenient for the operator to clean up later.

[0025] In addition, it should be noted that the above-mentioned flow aid storage bin 1 and the sealing cover 2 are connected by a clamp, which is not shown in the figure and is a prior art, so it will not be elaborated in detail here.

Then, under the action of the vertical alignment of the quantitative hole 4042 and the discharge pipe 3, the flow aid powder inside the flow aid storage bin 1 can fall into the inside of the quantitative hole 4042 through the discharge pipe 3. When a quantitative amount of flow aid powder flows into the quantitative hole 4042, After the powder is discharged, the rotating cylinder 501 is started to drive the rotating shaft 4041 to rotate ninety degrees, so that the connecting groove 4022 is horizontally connected with the metering hole 4042, and then the air compressor 403 is started to spray the quantitative flow aid powder inside the metering hole 4042 (the working principles of the quantitative discharging mechanism 4 and the driving mechanism 5 are as described above). When it is necessary to remove the guide mechanism 6, the sealing cover 2 is removed from the top of the flow aid storage bin 1 by opening the clamp, and then the guide mechanism 6 is moved upward so that the two groups of engaging balls 603 are again moved away from each other under the squeezing action of the engaging rod 604, so that the engaging balls 603 are no longer stuck in the slot 6041, and then the guide mechanism 6 can be removed, which is convenient for the operator to clean up later (the working principle of the guide mechanism 6 is as described above).
