Description

Technical Field

[0001] This invention relates to the field of automotive coating technology, specifically to a phosphating spraying device for coating aluminum alloy die-cast parts. Background Technology

[0002] Automotive painting refers to applying a layer of paint to the surface of a car to protect it. Automotive painting typically uses baked enamel. In car manufacturing plants, after the frame and body are welded, the next step is painting. Types of paint include regular paint, metallic paint, and pearlescent paint. The automotive painting process includes: puttying, sanding, and painting.

[0003] Chinese patent CN218774516U discloses a phosphating spraying device for automotive painting, including a spraying chamber. An air outlet is fixedly connected to the upper end of the spraying chamber. A fan mounting cavity is formed at one end of the air outlet, and a guide fan is fixedly engaged inside the fan mounting cavity. An ultraviolet lamp is fixedly connected to one side of the air outlet. A collection drawer is slidably connected to the lower end of the air outlet, and a filter layer is provided in the upper middle part of the collection drawer. This invention, through the arrangement of the spraying chamber and the collection drawer, allows for the following operation: when the guide fan is turned on, it circulates the air, and simultaneously, a water pump is activated, drawing water from the lower end of the collection drawer and spraying it out through an atomizing nozzle. The water is sprayed out as a mist, thereby suppressing dust and other particles in the flowing air, preventing dust from contacting the ultraviolet lamp and ensuring its long-term operation.

[0004] The above structure uses water spraying to suppress dust. The dust falls directly onto the filter layer. Since there is only one filter layer, when a lot of dust accumulates on it, the entire equipment needs to be shut down, the filter layer needs to be removed, and the dust on the filter layer needs to be cleaned, which will affect the working efficiency of the equipment. At the same time, the air circulation inside the exhaust pipe is guided by the exhaust fan, which causes some dust in the air to pass through the spray range of the atomizing nozzle. As a result, some dust will still adhere to the outer wall of the ultraviolet lamp. Over time, the dust remaining on the surface of the ultraviolet lamp will affect the normal use of the ultraviolet lamp. Summary of the Invention

Detailed Implementation

[0033] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figure 1 — Figure 3 As shown, the present invention provides: a phosphating spraying device for coating aluminum alloy die-cast parts, comprising a spraying chamber 1, a dust suppression component 2, and a disinfection component 3. The top of the spraying chamber 1 is provided with an exhaust pipe 11 and an exhaust fan 12. One end of the exhaust pipe 11 communicates with the interior of the spraying chamber, and the other end of the exhaust pipe 11 is connected to the exhaust fan 12. The dust suppression component 2 is disposed inside the exhaust pipe 11, and the disinfection component 3 is disposed between the exhaust pipe 11 and the exhaust fan 12. The dust suppression component 2 includes... It includes an atomizing nozzle 21, a water tank 22, a water pump 23, and a dust collection plate 24. The atomizing nozzle 21 extends from the top of the exhaust pipe 11 into the interior of the exhaust pipe 11. The water tank 22 and the water pump 23 are respectively located at the top of the spraying chamber 1 and are connected by a water pipe. The water pump 23 is also connected to the atomizing nozzle 21 by a water pipe. The dust collection plate 24 is located at the bottom of the inner cavity of the exhaust pipe 11 and is directly below the atomizing nozzle 21.

[0035] One end of the exhaust duct 11 is connected to the interior of the spray booth 1, and the other end is connected to the exhaust fan 12. When a vehicle enters the spray booth 1 for spraying, the exhaust fan 12 at the top of the spray booth 1 starts working, causing the air and dust inside the spray booth 1 to flow outwards along the exhaust duct 11. When the dust reaches above the dust collection plate 24, the water pump 23 starts working, sending water from the water tank 22 into the atomizing nozzle 21, which then sprays water into the exhaust duct 11. This allows the airborne dust to come into contact with the moisture, thus reducing the dust. The dust that has come into contact with the moisture falls onto the dust collection plate 24. The air collected and guided by the exhaust fan 12 continues to flow outward, and then passes through the disinfection component 3 at the outlet of the exhaust duct 11. The disinfection component 3 performs UV photolysis on harmful substances in the air, thereby ensuring that the air discharged by the exhaust fan 12 will not damage the surrounding space. Since the air flowing inside the exhaust duct 11 is guided by the exhaust fan 12, some dust will directly pass through the spraying area of ​​the atomizing nozzle 21 and then reach the exhaust fan 12 and be discharged. In order to avoid dust from damaging the environment, a filter component can be installed at the air outlet of the exhaust fan 12 to intercept and collect residual dust in the air, thereby protecting the environment around the spray booth 1.

[0036] Reference Figure 4 and Figure 5 As shown: The dust collection component 2 further includes a connecting block 25, a dust collection chamber 26, and a storage box 27; there are two dust collection plates 24, which are slidably connected to the bottom end of the inner cavity of the exhaust pipe 11; the connecting block 25 is disposed between the two dust collection plates 24 and connected to the two dust collection plates 24; the dust collection chamber 26 consists of two scraping chambers and a connecting chamber for connecting the two scraping chambers, the two scraping chambers are respectively located on both sides of the exhaust pipe 11, and scrapers are provided inside the scraping chambers; the connecting chamber is located at the bottom end of the exhaust pipe 11; the storage box 27 is located inside the dust collection chamber 26.

[0037] The dust collection plate 24 is embedded in the bottom end of the inner cavity of the exhaust pipe 11, and is slidably connected to the inner wall of the exhaust pipe 11. The sliding direction of the dust collection plate 24 is parallel to the line connecting the two side walls of the exhaust pipe 11. There are two dust collection plates 24 connected by a connecting block 25. When in use, only one dust collection plate 24 is inside the exhaust pipe 11, while the other dust collection plate 24 moves from inside the exhaust pipe 11 into the scraper bin. 4. After continuous dust collection, a large amount of dust will accumulate on the surface of the dust collection plate 24. To clean the dust from the dust collection plate 24, it is moved to the outside of the exhaust duct 11, and then further moved into the scraper bin on the other side of the exhaust duct 11. When the dust collection plate 24 enters the scraper bin, its top tip first abuts against the scraper inside the scraper bin. Then, as the dust collection plate 24 continues to move into the scraper bin, the… The scraper removes dust from the dust collection plate 24 grid until it is completely inside the scraper bin. Simultaneously, another dust collection plate 24 moves from the other side of the scraper bin into the exhaust duct 11. When the dust collection plate 24 with accumulated dust is completely inside the scraper bin, the clean dust collection plate 24 is positioned at the bottom of the exhaust duct 11, thus continuing to collect the falling dust. This ensures that the dust collection component 2 operates without interrupting dust removal, thereby guaranteeing work efficiency. The scraping bin is equipped with a middle plate, which divides the inside of the scraping bin into a scraping area and a collection area. The scraping area is located above the collection area. There is a certain distance between the two ends of the middle plate and the two inner side walls of the scraping bin, so that after the scraper scrapes the dust off the dust collection plate 24, the dust can enter the collection area through the gap between the middle plate and the scraping bin. The collection box 27 passes through the two collection areas and the connecting bin from the outside of the dust collection bin 26, so that the collection box 27 can collect the dust from the two scraping bins at the same time.

[0038] Reference Figure 5 As shown: A scraper bin is equipped with a first motor 28 and a first lead screw 29; the first lead screw 29 extends from one side of the exhaust pipe 11 to the other side of the exhaust pipe 11 and passes through the connecting block 25. The first lead screw 29 is rotatably connected to the exhaust pipe 11 and threadedly connected to the connecting block 25; the first motor 28 is located inside the scraper bin and fixed on the side wall of the exhaust pipe 11. The first motor 28 is fixedly connected to the first lead screw 29.

[0039] The two dust collection plates 24 are connected by a connecting block 25. The dust collection plates 24 and the connecting block 25 are slidably connected to the bottom end of the inner cavity of the exhaust pipe 11. The first lead screw 29 passes through the exhaust pipe 11 and the connecting block 25, and is threadedly connected to the connecting block 25. Thus, driven by the first motor 28, the connecting block 25 can drive the two dust collection plates 24 to move at the bottom end of the inner cavity of the exhaust pipe 11, thereby completing the work of replacing the dust collection plates 24.

[0040] Reference Figure 6 and Figure 7 As shown: The disinfection component 3 includes a lamp chamber 31, ultraviolet lamps 32, and a cleaning component 33; the lamp chamber 31 is located between the exhaust pipe 11 and the exhaust fan 12; the cleaning component 33 is located inside the lamp chamber 31; there are several ultraviolet lamps 32 distributed vertically at intervals inside the lamp chamber 31, and the ultraviolet lamps 32 pass through the cleaning component 33; the lamp chamber 31 is also provided with a drive component 35 for moving the cleaning component 33 and a transmission component 34 for cleaning the ultraviolet lamps 32.

[0041] The lamp chamber 31 is located between the exhaust duct 11 and the exhaust fan 12, so that the ultraviolet lamp 32 can perform UV photolysis on harmful substances in the air, thereby preventing harmful substances from being emitted into the outside air. The axis of the ultraviolet lamp 32 is parallel to the horizontal plane, and the two ends of the ultraviolet lamp 32 are respectively inserted into the two side walls inside the lamp chamber 31. At the same time, because the exhaust fan 12 continuously guides the air inside the exhaust duct 11, some dust in the exhaust duct 11 will pass through the dust collection component 2 and the disinfection component 3. Therefore, after a long period of time, the outer surface of the ultraviolet lamp 32 is easily cleaned. Dust can accumulate, affecting the normal operation of the ultraviolet lamp 32. Therefore, a cleaning component 33 is installed inside the lamp chamber 31. Under the control of the drive component 35, the cleaning component 33 reciprocates along the axis of the ultraviolet lamp 32. Simultaneously, while the cleaning component 33 is moving, the transmission component 34 drives the cleaning component 33 to clean the outer surface of each ultraviolet lamp 32, thereby ensuring the cleanliness of the surface of the ultraviolet lamp 32. This allows the ultraviolet lamp 32 to stably disinfect harmful substances in the air and prevents harmful substances from being emitted into the outside air.

[0042] Reference Figure 8 As shown: The cleaning assembly 33 includes a cleaning chamber 331, a cleaning box 332, a first rotating shaft 333, and a first pulley 334. The cleaning chamber 331 is located inside the lamp chamber 31. The interior of the cleaning chamber 331 is provided with several vertically spaced bushings. The inner peripheral wall of the bushings is in contact with the outer peripheral wall of the ultraviolet lamp 32. The interior of the cleaning chamber 331 is also provided with a vertical plate for connecting the bushings. There are two cleaning boxes 332, which are respectively located on both sides of the cleaning chamber 331. The cleaning boxes 332 are inserted into the cleaning chamber 331 from the outside. The first rotating shaft 333 is respectively located at the top and bottom of the cleaning box 332. The first pulley 334 is sleeved on the first rotating shaft 333. A first synchronous belt 335 is rotatably installed between the two first pulleys 334. The outer peripheral wall of the first synchronous belt 335 is provided with a brush.

[0043] The cleaning chamber 331 is slidably disposed inside the lamp chamber 31, and all ultraviolet lamps 32 in the lamp chamber 31 pass through the cleaning chamber 331. Each ultraviolet lamp 32 passes through a bushing, and each bushing has inclined surfaces at both ends. When the drive assembly 35 controls the cleaning chamber 331 to move axially along the ultraviolet lamps 32, the bushings remove dust from the ultraviolet lamps 32 through the inclined surfaces, and transport the dust into the cleaning chamber 331. Subsequently, all the dust falls to the bottom of the inner cavity of the cleaning chamber 331. The cleaning boxes 332 embedded on both sides of the cleaning chamber 331 begin to clean the dust remaining on the bushing, thereby ensuring that all dust entering the cleaning chamber 331 falls to the bottom of the inner cavity of the cleaning chamber 331. The top and bottom of the inner cavity of the cleaning chamber 331 are each provided with a first rotating shaft 333, and each first rotating shaft 333 is fitted with a first pulley 334. A first synchronous belt 335 is rotatably mounted between two first pulleys 334. The outer peripheral wall of the first synchronous belt 335 is provided with a brush. Simultaneously, a first rotating shaft 332 is located at the top of the cleaning box 332. Shaft 333 is connected to transmission assembly 34, so that when drive assembly 35 controls cleaning chamber 331 to move, transmission assembly 34 controls first rotating shaft 333 to rotate, thereby causing first synchronous belt 335 to clean the outer surface of each bushing, thus preventing dust residue from remaining on the bushing; one side wall inside lamp chamber 31 is provided with a receiving chamber for accommodating cleaning chamber 331, so that under the control of drive assembly 35, cleaning chamber 331 first moves from inside the receiving chamber to the other side of lamp chamber 31, thereby cleaning the outer surface of ultraviolet lamp 32 of residue. The dust is cleaned. After the cleaning chamber 331 reaches the other side of the lamp chamber 31, the drive component 35 controls the cleaning chamber 331 to move in the opposite direction, so that the cleaning chamber 331 moves into the receiving chamber, thereby completing the secondary cleaning of the ultraviolet lamp 32, ensuring that the surface of the ultraviolet lamp 32 is cleaned, thus ensuring the disinfection efficiency of the ultraviolet lamp 32 against harmful substances. After the cleaning chamber 331 returns to the receiving chamber under the control of the drive component 35, the drive component 35 stops working, thus waiting for the next cleaning of the ultraviolet lamp 32.

[0044] Reference Figure 7 As shown: The bottom end of the lamp chamber 31 is provided with a slide rail 336, the working direction of the slide rail 336 is parallel to the axial direction of the ultraviolet lamp 32; the bottom end of the cleaning chamber 331 is inserted into the slide groove and the bottom end of the cleaning chamber 331 is provided with a slider 337, and the bottom end of the cleaning chamber 331 is provided with an opening that extends into the interior of the cleaning chamber 331; the slider 337 is slidably connected to the inner side wall of the slide groove; the bottom end of the slide rail 336 is also provided with a collection hopper 338, the top end of the collection hopper 338 is fixedly connected to the bottom end of the slide rail 336.

[0045] The bottom end of the lamp chamber 31 is provided with a slide rail 336, and the bottom end of the cleaning chamber 331 is inserted into the slide rail and slidably connected to the slide rail 336 through a slider 337 on the outside. This provides guidance and assistance to the cleaning chamber 331 when the drive assembly 35 drives it to move. Simultaneously, the bottom end of the slide rail 336 is provided with a collection hopper 338, the top end of which is connected to the bottom end of the slide rail 336, and the bottom end of which is connected to the interior of the dust collection chamber 26. The bottom of the cleaning chamber 331 has an opening that extends into the interior. When dust is scraped into the cleaning chamber 331 through the bushing and falls to the bottom of the cleaning chamber 331, the dust can pass through the bottom of the cleaning chamber 331 and the slide 336 until it enters the interior of the collection hopper 338. Then, the dust enters the dust collection chamber 26 through the collection hopper 338. This can collect the dust generated during the spraying work, thereby preventing the dust from escaping into the air and ensuring the health of the surrounding environment and the health of the surrounding workers.

[0046] Reference Figure 8 and Figure 9 As shown: The transmission assembly 34 includes a transmission chamber 341, a second rotating shaft 342, a second pulley 343, and a third pulley 344; the transmission chamber 341 is located at the top of the cleaning chamber 331; there are two second rotating shafts 342, which are respectively located on both sides of the inner cavity of the transmission chamber 341, and the axial direction of the second rotating shafts 342 is parallel to the axial direction of the ultraviolet lamp 32; the second pulley 343 is sleeved on the second rotating shaft 342; the third pulley 344 is sleeved on the first rotating shaft 333 near the top of the cleaning chamber 331; a second synchronous belt 345 is rotatably installed between the second pulley 343 and the third pulley 344.

[0047] The transmission component 34 is connected to the top of the inner cavity of the lamp chamber 31, so that when the drive component 35 controls the cleaning chamber 331 to move, the transmission component 34 can follow and rotate, thereby enabling the second rotating shaft 342 to drive the second pulley 343 to rotate. Subsequently, the second pulley 343 drives the first rotating shaft 333 to rotate through the second synchronous belt 345 and the third pulley 344. Thus, while the drive component 35 controls the cleaning chamber 331 to move linearly, the first synchronous belt 335 inside the cleaning box 332 can follow and rotate, thereby cleaning the bushing inside the cleaning chamber 331, thus ensuring that the dust inside the cleaning chamber 331 is swept to the bottom of the cleaning chamber 331.

[0048] Reference Figure 10As shown: The drive assembly 35 includes a second motor 351, a second lead screw 352, a rack and pinion box 353, and a first gear 354; the second motor 351 is located on the outside of the lamp chamber 31, and the output shaft of the second motor 351 passes through the outside of the lamp chamber 31 and into the inside of the lamp chamber 31; the second lead screw 352 is located inside the lamp chamber 31, and the axis of the second lead screw 352 is parallel to the axis of the ultraviolet lamp 32. One end of the second lead screw 352 is fixedly connected to the output shaft of the second motor 351, and the other end of the second lead screw 352 passes through the transmission chamber 341 and rotates with the inner wall of the lamp chamber 31. The second lead screw 352 is threadedly connected to the transmission chamber 341; two rack boxes 353 are arranged parallel to each other at the top of the inner cavity of the lamp chamber 31, and the two ends of the rack box 353 are slidably connected to the inner wall of the lamp chamber 31, with the sliding direction of the rack box 353 perpendicular to the axial direction of the ultraviolet lamp 32; racks are respectively provided on the two side walls of the inner cavity of the rack box 353; the first gear 354 is disposed inside the rack box 353, and the outer peripheral wall of the first gear 354 meshes with the rack on one side inside the rack box 353; the transmission assembly 34 is connected to the first gear 354.

[0049] The inner walls of the rack box 353 are respectively provided with a first rack and a second rack. Since the two rack boxes 353 are arranged parallel to each other at the top of the lamp chamber 31, the first racks in the two rack boxes 353 are close to each other, while the second racks are far apart. When it is necessary to drive the cleaning chamber 331 to reciprocate along the axial direction of the ultraviolet lamp 32, the second motor 351 installed on the outer wall of the lamp chamber 31 first starts. Then, the second motor 351 drives the transmission chamber 341 to move linearly through the second lead screw 352. At the same time, the transmission chamber 341 drives the cleaning chamber 331 to move together, so that the cleaning chamber 331 can collect the dust on the outer peripheral wall of the ultraviolet lamp 32 into the cleaning chamber 331. The transmission assembly 34 is connected to the first gear 354 so that when the cleaning chamber 331 moves, the transmission assembly 34 can move synchronously with the first gear 354. At the same time, since the first gear 354 meshes with the rack on the inner side wall of the rack box 353, the first gear 354 can drive the transmission assembly 34 to rotate, so that the two second rotating shafts 342 inside the transmission chamber 341 can rotate synchronously. Then, the second synchronous belt 345 drives the first rotating shaft 333 to rotate, so that the first synchronous belt 335 can clean the dust remaining on the bushing with the brush set on the outer peripheral wall, thus ensuring that all the dust entering the cleaning chamber 331 falls to the bottom of the cleaning chamber 331.

[0050] Reference Figure 9As shown: The transmission assembly 34 further includes a third rotating shaft 346, a first bevel gear 347, and a second bevel gear 348; there are two third rotating shafts 346, which are respectively arranged on both sides of the inner cavity of the transmission chamber 341. One end of the third rotating shaft 346 extends upward from the inside of the transmission chamber 341 to the inside of the rack box 353 and is fixedly connected to the first gear 354; the first bevel gear 347 and the second bevel gear 348 mesh with each other and are located inside the transmission chamber 341. The first bevel gear 347 is sleeved on the third rotating shaft 346, and the second bevel gear 348 is sleeved on the second rotating shaft 342.

[0051] Two rack boxes 353 are arranged parallel to each other at the top of the inner cavity of the lamp chamber 31, so that two first gears 354 are synchronously arranged inside the corresponding rack boxes 353. Two third rotating shafts 346 extend from the inside of the transmission chamber 341 to the top of the transmission chamber 341 and are inserted into the corresponding rack boxes 353. The third rotating shafts 346 are fixedly connected to the first gears 354 inside the rack boxes 353. The other end of the third rotating shafts 346 is connected to the second rotating shaft 342 via a first bevel gear 347 and a second bevel gear 348. When the cleaning chamber 331 is controlled to move linearly by the second motor 351, the third rotating shafts 346 drive the first gears 354 to move synchronously. Simultaneously, the first gears 354 mesh with the inner wall of the rack boxes 353, so that when the first gears 354 move synchronously, they can also drive the third rotating shafts 346 to rotate synchronously. The movement of the first synchronous belt 335 causes the third rotating shaft 346 to drive the second rotating shaft 342 to rotate synchronously via the first bevel gear 347 and the second bevel gear 348. This, in turn, causes the second rotating shaft 342 to drive the first synchronous belt 335 to rotate synchronously via the second synchronous belt 345. Thus, while the cleaning chamber 331 moves, the first synchronous belt 335 cleans the dust on the bushing inside the cleaning chamber 331. Since the two cleaning boxes 332 are respectively located on both sides of the cleaning chamber 331, and the first synchronous belt 335 inside each cleaning box 332 needs to sweep the dust downwards, the two first synchronous belts 335 rotate in opposite directions. Therefore, when driving the cleaning chamber 331 away from the receiving chamber, each first gear 354 needs to mesh with the second rack inside the rack box 353. This allows the two first gears 354 to rotate in opposite directions while simultaneously driving the first synchronous belt 335 to sweep the dust on the bushing downwards.

[0052] Reference Figure 11 and Figure 12As shown: The drive assembly 35 further includes an outer push plate 355 and a compression spring 356; the outer push plate 355 is located inside the two rack boxes 353, and several first inclined blocks 3551 are provided on both sides of the outer push plate 355 at intervals along the length direction of the outer push plate 355; the compression spring 356 is located at the top of the inner cavity of the lamp chamber 31 and is located on the outer side of the two rack boxes 353 respectively, and the two ends of the compression spring 356 are connected to the rack box 353 and the lamp chamber 31 respectively; the inner sides of the two rack boxes 353 are respectively provided with second inclined blocks 3531 that abut against and cooperate with the first inclined blocks 3551.

[0053] The top of the transmission chamber 341 is provided with a protrusion that inserts into the outer push plate 355. When the second motor 351 controls the cleaning chamber 331 to move away from the receiving chamber, each first gear 354 meshes with the second rack inside the rack box 353, thereby enabling the two first synchronous belts 335 to rotate in opposite directions, thus cleaning the inside of the cleaning chamber 331. When the cleaning chamber 331 has completely moved to the other side of the lamp chamber 31, the protrusion at the top of the transmission chamber 341 drives the outer push plate 355 to move, so that the first inclined block 3551 on the outer side of the outer push plate 355 abuts against the second inclined block 3531 on the inner side of the rack box 353, and the two rack boxes 353 move away from the outer push plate 355 through the inclined sliding, thereby compressing the spring. Spring 356 is compressed, causing the first rack to engage with the first rack inside the rack box 353. Then, when the second motor 351 drives the cleaning chamber 331 closer to the receiving chamber, the two switched first gears 354 still drive the two first synchronous belts 335 to rotate in opposite directions and sweep the dust inside the cleaning chamber 331 downwards until the cleaning chamber 331 is completely inside the receiving chamber. At this time, the outer push plate 355 moves in the same direction through the protrusion at the top of the transmission chamber 341, causing the first inclined block 3551 to disengage from the second inclined block 3531. The compressed spring 356 starts to drive the rack box 353 closer to the outer push plate 355, so that the first gear 354 starts to engage with the second rack inside the rack box 353, thus waiting for the next cleaning operation.
