Description

Technical Field

[0001] This utility model relates to the field of coating production, and in particular to a dust-proof material delivery device. Background Technology

[0002] In the production process of coatings, packaged powder needs to be fed into the processing equipment. Since dust will be scattered when the powder is poured, dust-free feeding stations are mostly used to prevent dust from scattering. Dust-free feeding stations use filter cartridges to prevent dust from scattering. However, long-term accumulation leads to a decrease in the air permeability of the filter cartridges and a reduction in dust removal efficiency. Moreover, existing cleaning methods mostly involve manual disassembly, cleaning, or replacement of the filter cartridges, which is cumbersome and affects the continuity of production. At the same time, manual cleaning is prone to secondary dust pollution and waste of powder. Therefore, this utility model proposes a dust-proof material feeding device that can prevent dust from scattering and recover and feed the cleaned dust while cleaning the filter cartridges. Utility Model Content

[0003] To overcome these shortcomings, the technical problem of this utility model is to provide a dust-proof material feeding device.

[0004] Technical Solution: A dust-proof material delivery device includes an installation frame, a barrier fixed to the installation frame, a top plate fixed to the top of the barrier, a baffle rotatably connected to the top plate, a dust collection assembly on the top plate, the dust collection assembly including a fan on the top plate, a connecting pipe on the top plate connected to the air intake of the fan, a filter element at the bottom of the top plate communicating with the connecting pipe, a dust brushing assembly on the top plate including a fixed pipe fixed to the bottom of the top plate, the fixed pipe being located outside the filter element, a guide pipe connected to the bottom of the fixed pipe, a rotating pipe rotatably connected to the inner wall of the fixed pipe, a guide groove on the rotating pipe, ventilation openings on both the rotating pipe and the fixed pipe, an electric push rod on the top plate, a brush ring fixed to the telescopic end of the electric push rod, the brush ring being located between the rotating pipe and the filter element, the brush ring contacting the filter element, and a protrusion on the brush ring slidably connected to the guide groove.

[0005] Furthermore, it is particularly preferred that a placement frame is fixedly connected to the mounting frame, a hopper is fixedly connected to the bottom of the mounting frame, and support frames are provided on both sides of the mounting frame.

[0006] Furthermore, it is particularly preferred that the mounting frame has a placement plate extending on the side facing the same direction as the baffle for convenient placement of the material bag.

[0007] Furthermore, it is particularly preferred that the guide groove consists of an inclined groove and a vertical groove, with the protrusion located within the inclined groove.

[0008] Furthermore, it is particularly preferred that the outer wall of the rotating tube is in contact with the inner wall of the fixed tube, and that the number of vents on the rotating tube and the fixed tube is the same.

[0009] Furthermore, it is particularly preferred that the fan and the electric push rod are controlled by the same controller. When the fan is running, the electric push rod remains in the retracted state, and when the fan is turned off, the electric push rod extends.

[0010] Furthermore, it is particularly preferred that the inner side of the baffle is provided with a rubber membrane.

[0011] Compared with the prior art, this utility model has the following advantages: This utility model uses a fan to draw air in, and after the powder is poured in, the scattered powder will be adsorbed on the surface of the filter element, thereby preventing dust from spreading everywhere. In addition, an electric push rod is set to drive the ring brush to move and brush off the dust adsorbed on the filter element. Furthermore, a rotating tube and a fixed tube are provided on the outside of the filter element. The opening and closing of the ventilation port is controlled by the movement of the ring brush, which not only cleans the filter element and extends its service life, but also reduces material loss.

Detailed Implementation

[0017] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0018] Example: A dust-proof material delivery device, such as... Figures 1-4As shown, the device includes an installation frame 1, a placement rack 100 fixedly connected to the installation frame 1, a hopper 2 fixedly connected to the bottom of the installation frame 1, and support frames 6 on both sides of the installation frame 1. A enclosure 3 is fixedly connected to the installation frame 1, a top plate 4 is fixedly connected to the top of the enclosure 3, and a baffle 5 is rotatably connected to the top plate 4. A placement plate for convenient placement of material bags extends from the side of the installation frame 1 facing the same direction as the baffle 5. A rubber membrane is provided on the inner side of the baffle 5 to ensure a sealed environment and prevent dust from escaping. A dust collection assembly is provided on the top plate 4.

[0019] The dust collection assembly includes a fan 7 mounted on the top plate 4, a connecting pipe 8 mounted on the top plate 4, the connecting pipe 8 being connected to the air intake of the fan 7, a filter element 9 being mounted at the bottom of the top plate 4, the filter element 9 being connected to the connecting pipe 8, and a dust brushing assembly being mounted on the top plate 4. After the powder is poured in, the fan 7 starts to draw in the scattered dust, and the dust will be adsorbed onto the surface of the filter element 9.

[0020] The dust brushing assembly includes a fixed tube 10 fixed to the bottom of the top plate 4, located outside the filter element 9. A guide tube 11 is connected to the bottom of the fixed tube 10. A rotating tube 12 is rotatably connected to the inner wall of the fixed tube 10, with the outer wall of the rotating tube 12 contacting the inner wall of the fixed tube 10. The number of ventilation openings on the rotating tube 12 and the fixed tube 10 is the same. A guide groove 121 is formed on the rotating tube 12, consisting of an inclined groove and a vertical groove. A protrusion 15 is located within the inclined groove. Ventilation openings are provided on both the rotating tube 12 and the fixed tube 10. An electric push rod 13 is provided on the top plate 4, with a brush ring 14 fixed to the telescopic end of the electric push rod 13. The brush ring 14 is located on the rotating tube 12. Between the filter element 9 and the brush ring 14, the brush ring 14 is in contact with the filter element 9. The brush ring 14 is provided with a protrusion 15, which is slidably connected to the guide groove 121. The telescopic end of the electric push rod 13 extends and drives the brush ring to move downward. While the brush ring moves downward, the protrusion 15 will squeeze the guide groove 121. Under the action of the inclined groove of the guide groove 121, the rotating tube 12 will rotate at a certain angle. The rotation of the rotating tube 12 will block the vent on the fixed tube 10. When it is completely blocked, the protrusion 15 will move from the inclined groove to the vertical groove. The rotating tube 12 remains stationary. At the same time, the brush ring 14 moves downward and scrapes off the dust adsorbed on the filter element 9. The scraped dust will fall into the feed hopper 2 below along the feed guide tube 11.

[0021] The fan 7 and the electric push rod 13 are controlled by the same controller. When the fan 7 is running, the electric push rod 13 remains in the retracted state. When the fan 7 is turned off, the electric push rod 13 extends.

[0022] In use, the feeding device is positioned above the machine hopper where materials need to be fed, via the support frame 6. The feeding hopper 2 is connected to the machine hopper. Then, the baffle 5 is opened, the fan 7 is started, and the powder from the material bag is poured in. The baffle 5 is then closed, and the fan 7 starts to suck up the scattered dust. The dust is adsorbed onto the surface of the filter element 9, thus preventing the dust from scattering. The unscattered powder is fed through the feeding hopper 2. After adsorption for a period of time, the fan 7 is turned off, and the telescopic end of the electric push rod 13 extends, driving the ring brush downward. As the ring brush moves downward, the protrusion 15 squeezes the guide groove 121. Under the action of the inclined groove of the guide groove 121, the rotating tube 12 will rotate at a certain angle. The rotation of the rotating tube 12 will move the solid... When the vent on the fixed pipe 10 is completely blocked, the protrusion 15 will move from the inclined groove into the vertical groove, while the rotating pipe 12 remains stationary. At the same time, the brush ring 14 moves downward and scrapes off the dust adsorbed on the filter element 9. The scraped dust will fall into the lower hopper 2 along the guide pipe 11, thus scraping off the adsorbed dust for feeding. This cleans the filter element 9, extends its service life, and reduces material loss. After the brush ring 14 moves downward to the bottom, the telescopic end of the electric push rod 13 resets, driving the ring brush to reset. The ring brush resets along the vertical groove. After the protrusion 15 enters the inclined groove, the rotating pipe 12 gradually resets, and the vent on the fixed pipe 10 opens. Repeating the above operation can achieve the effect of preventing dust during feeding.
