Description

Technical Field

[0001] The present 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 multiple industries such as food, pharmaceuticals, chemicals, plastics, and cosmetics to ensure a smooth production process and improve product quality. However, flow aid 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. This increases batch-to-batch differences, affects product performance and user experience, and leads to decreased customer satisfaction and weakened market competitiveness. In addition, during the discharge process of the flow aid spraying device, if the material inside the tank containing the flow aid agglomerates or flows unevenly due to static electricity, the flow of the flow aid will be poor during discharge, greatly affecting the discharge efficiency of the flow aid.

By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] According to an embodiment of the present invention, a flow aid quantitative powder spraying device is provided.

[0028] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figures 1-10 As shown, the flow aid quantitative powder spraying device according to an embodiment of the present invention includes a flow aid storage bin 1, a sealing cover 2 is provided at the top of the flow aid storage bin 1, a discharge pipe 3 is provided at the bottom of the flow aid storage bin 1, a quantitative discharge mechanism 4 is provided at the bottom of the discharge pipe 3, a driving mechanism 5 is connected to one side of the quantitative discharge mechanism 4, and a flow guide mechanism 6 is provided inside the flow aid storage bin 1.

[0029] With the help of the above-mentioned technical scheme of the present invention, the present invention can not only spray out a quantitative amount of flow aid powder through the coordinated arrangement of the flow aid holding bin 1, the sealing cover 2, the discharge pipe 3, the quantitative discharge mechanism 4, the driving mechanism 5 and the guide mechanism 6, thereby reducing the risk of inaccurate manual weighing, ensuring the stability of product quality, improving product performance and user experience, but also ensuring good fluidity of the flow aid powder during discharge, avoiding uneven flow of the flow aid powder, and improving the discharge efficiency of the flow aid powder.

[0030] In one embodiment, for the above-mentioned quantitative discharging mechanism 4 and driving mechanism 5, the quantitative discharging mechanism 4 includes a quantitative block 401 arranged at the bottom end of the discharge pipe 3, a cavity assembly 402 is interspersed inside the quantitative block 401, one end of the cavity assembly 402 is connected to an air compressor 403, and a quantitative assembly 404 is arranged inside the cavity assembly 402; the cavity assembly 402 includes a quantitative groove 4021 arranged inside the quantitative block 401, and the cross section of the quantitative groove 4021 is a cylindrical structure, and both sides of the quantitative groove 4021 are provided with connecting grooves 4022 that penetrate the quantitative block 401, wherein one group of connecting grooves 4022 is connected to the air compressor 403; the quantitative assembly 404 includes a rotating shaft 4041 arranged inside the quantitative groove 4021, and a quantitative hole 4042 that cooperates with the discharge pipe 3 is opened on the outer side of the rotating shaft 4041; the connecting groove 4022 and the quantitative hole 4042 are matched with each other, and the quantitative groove A connection is set between 4021 and the discharge pipe 3; the driving mechanism 5 includes a rotating cylinder 501 arranged at one end of the quantitative component 404, and the quantitative component 404 and the rotating cylinder 501 are connected by a connecting sleeve 502; under the action of the quantitative hole 4042 being connected to the discharge pipe 3, the fluidizer powder inside the fluidizer storage bin 1 can fall into the interior of the quantitative hole 4042 through the discharge pipe 3. After the quantitative fluidizer powder flows into the interior of the quantitative hole 4042, the rotating cylinder 501 is started to drive the rotating shaft 4041 to rotate ninety degrees, and then the air compressor 403 is started to spray out the quantitative fluidizer powder, thereby reducing the risk of inaccurate manual weighing, realizing random and automatic quantitative addition of fluidizer, 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.

[0031] In addition, it should be noted that the above-mentioned rotating cylinder 501 is a ninety-degree rotating cylinder. The rotating cylinder 501 is composed of a cylinder body, a piston, a rotating shaft, a solenoid valve and a limit switch. The working principle of the rotating cylinder 501 is that the linear motion of the piston is converted into the rotational motion of the rotating shaft through a mechanical connection to achieve angular rotation. The composition and working principle of this rotating cylinder 501 are existing technologies and will not be elaborated on here.

[0032] In addition, it should be noted that the rotating end of the rotating cylinder 501 is connected to one end of the rotating shaft 4041 via a connecting sleeve 502. This is a prior art and will not be elaborated on here.

[0033] In addition, it should be noted that the above-mentioned air compressor 403 is composed of an electric motor, a compressor, an air intake valve, an exhaust valve, an air storage tank and a filter. The working principle of the air compressor 403 is to start the electric motor to make the compressor compress the air, and output the compressed air through the exhaust valve for use. This air compressor 403 is an existing technology and will not be elaborated on here.

[0034] The working principle of the quantitative discharging mechanism 4 and the driving mechanism 5: 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. After the quantitative flow aid powder flows into the inside of the quantitative hole 4042, the rotating cylinder 501 is started to drive the rotating shaft 4041 to rotate ninety degrees, so that the connecting groove 4022 is horizontally aligned and connected with the quantitative hole 4042, and then the air compressor 403 is started to spray out the quantitative flow aid powder inside the quantitative hole 4042, 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.

[0035] In one embodiment, for the above-mentioned flow guiding mechanism 6, the flow guiding mechanism 6 includes a fixing frame 601 symmetrically arranged on the inner wall of the flow aid storage bin 1, a spring 602 is symmetrically arranged inside the fixing frame 601, and a snap ball 603 is arranged at one end of the spring 602 away from the inner wall of the fixing frame 601, and a snap rod 604 that cooperates with the snap ball 603 is arranged inside the fixing frame 601, and a plurality of guide blocks 605 are arranged on the top of the snap rod 604, and a plurality of guide plates 606 are arranged on the outside of the guide block 605, and a connecting column 607 is arranged on the top of the plurality of guide blocks 605; the bottom end of the snap rod 604 is a V-shaped structure, and the bottom of the snap rod 604 is symmetrically provided with a snap groove 6041 that cooperates with the snap ball 603; the plurality of guide blocks 605 are evenly arranged and arranged in a The guide plates 606 are evenly arranged and circumferentially distributed on the outside of the guide block 605. Under the action of the trapezoidal distribution of the guide blocks 605 and the circumferential distribution of the guide plates 606, the flow aid powder falling due to gravity can be effectively dispersed and flowed, which helps to break up the agglomerates produced by the flow aid powder. At the same time, the circumferentially distributed flow guide plates 606 guide the material to the center, avoiding the retention of the material on the silo 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.

[0036] The working principle of the guide mechanism 6: the operator places the guide 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 guide mechanism 6 can be firmly placed in the flow aid storage bin 1. When the guide mechanism 6 needs to be removed, the guide 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 stuck in the locking groove 6041, and the guide mechanism 6 can be removed, which is convenient for the operator to clean later.

[0037] In addition, it should be noted that the flow aid storage bin 1 and the sealing cover 2 are connected via a clamp, which is not shown in the figure and is a prior art, so it will not be elaborated on here.

[0038] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in actual process is described in detail below.

[0039] In actual application, the operator places the flow-guiding mechanism 6 into the flow-aid holding bin 1, and at the same time moves the engaging rod 604 toward the inside of the fixing frame 601, so that the two sets of engaging balls 603 inside the fixing frame 601 move away from each other, and with the cooperation of the spring 602, the engaging balls 603 are engaged in the engaging groove 6041, so that the flow-guiding mechanism 6 can be firmly placed in the flow-aid holding bin 1 (the working principle of the flow-guiding mechanism 6 is as above), and then the flow-aid powder is put into the flow-aid holding bin 1, and the sealing cover 2 and the flow-aid holding bin 1 are sealed by the clamp, and then, under the action of the vertical alignment of the metering hole 4042 and the discharge pipe 3, the flow-aid powder inside the flow-aid holding bin 1 can fall into the inside of the metering hole 4042 through the discharge pipe 3. When a certain amount of flow-aid powder flows into the inside of the metering 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 to 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 sets 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 engaging groove 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).

[0040] In summary, with the aid of the above technical scheme of the present invention, through the coordinated arrangement of the flow aid storage bin 1, the sealing cover 2, the discharge pipe 3, the quantitative discharge mechanism 4, the driving mechanism 5 and the flow guiding mechanism 6, not only can a quantitative flow aid powder be sprayed out, reducing the risk of inaccurate manual weighing, ensuring the stability of product quality, improving product performance and user experience, but also can ensure good fluidity of the flow aid powder during discharge, avoid uneven flow of the flow aid powder, and improve the discharge efficiency of the flow aid powder; through the quantitative discharge mechanism 4 and the driving mechanism 5, 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 under the action of the quantitative hole 4042 being connected to the discharge pipe 3. After a quantitative flow aid powder flows into the inside of the quantitative hole 4042, by starting the rotating cylinder 501, the rotating cylinder 501 drives the rotating shaft 4041 to rotate ninety degrees, and then by starting the air compressor 403, the flow aid powder inside the flow aid storage bin 1 can be connected to the discharge pipe 3. Quantitative discharge of flow aid powder reduces the risk of inaccurate manual weighing, realizes random automatic quantitative addition of flow aid, ensures stable product quality, meets industry standards and regulatory requirements, avoids differences between product batches, improves product performance and user experience, and thus improves customer satisfaction and market competitiveness; through the flow guide mechanism 6, the flow aid powder falling due to gravity can be effectively dispersed and flowed under the action of the trapezoidal distribution of several guide blocks 605 and the circumferential distribution of several flow guide plates 606, which helps to break up the lumps produced by the flow aid powder. At the same time, the circumferentially distributed several flow guide plates 606 guide the material to the center, avoids the retention of the material on the silo wall, promotes continuous and stable flow, avoids uneven flow of the flow aid powder, and improves the discharge efficiency of the flow aid powder. Even under high flow or long-term operation, the good fluidity of the flow aid powder can be maintained, greatly improving the reliability and work efficiency of the entire device.
