Description
Technical Field
[0001] The invention relates to the field of electrophoretic painting, in particular to an electrophoretic paint treatment device applied to automobile accessories. Background Art
[0002] Electrophoretic painting can coat auto parts with a protective paint surface in all directions. Generally, the original paint of auto parts refers to electrophoretic painting. Before electrophoretic painting, the surface of auto parts needs to be degreased, acid-etched and other pre-treatments. After electrophoretic painting is completed, curing and drying treatment is also required, that is, the auto parts after electrophoretic painting are moved to the oven for drying.
[0003] An existing Chinese public document (CN114990670A) describes an electrophoretic paint treatment device for automobile parts. When the auto part is hoisted for electrophoretic treatment, a vibration component is designed. After the part emerges from the liquid surface, the first movable plate vibrates back and forth, thereby driving the part to vibrate, accelerating the dripping of residual electrophoretic paint on the surface of the part, achieving a better cleaning effect, ensuring the electrophoretic effect, and preventing the electrophoretic paint adhering to the surface of the auto part from continuing to drip slowly, resulting in waste of electrophoretic paint.
[0004] In the disclosed technical solution, after the auto parts are moved out of the liquid surface by a lifting structure, the auto parts are vibrated to accelerate the dripping of the electrophoretic paint on the surface of the auto parts, and then the auto parts are moved to the drying process for curing treatment. Although the reciprocating vibration of the auto parts can accelerate the dripping speed of the electrophoretic paint, it cannot be guaranteed that the electrophoretic paint on the surface of the auto parts can be completely removed by vibration alone before entering the drying box. That is, during the electrophoretic treatment line processing of auto parts, there will still be a small amount of dripping of the electrophoretic paint remaining on the surface of the auto parts after the auto parts leave the electrophoretic tank and enter the drying area. The electrophoretic paint dripping in the drying area not only causes waste of the electrophoretic paint, but also causes pollution to the drying area. For this reason, we propose an electrophoretic paint treatment device for auto parts. Summary of the Invention

The mounting frame plates 3 and the guide frame 1 are fixed to the interior of the oven by bolts. The end of the guide frame 1 close to the electrophoretic tank 37 is open, and a guide plate 4 is fixedly installed on the bottom of the guide frame 1. The guide frame 1 is tilted as a whole, and the open end of the guide frame 1 is tilted downward toward the electrophoretic tank 37; a scraping mechanism 5 is provided. A scraping mechanism 5 for moving the electrophoretic paint dripping on the upper end surface of the guide plate 4 is installed on the upper part of the guide plate 4, and a transmission component 9 for driving the scraping mechanism 5 is also provided inside the guide frame 1; an air supply mechanism 8 for accelerating the falling of the electrophoretic paint hanging on the surface of the automobile parts is installed at the bottom of the mounting frame 3, and the guide frame 1 is placed at an angle inside the oven. Under the movement of the scraping mechanism 5, the electrophoretic paint on the automobile parts can be prevented from dripping into the interior of the oven, and the electrophoretic paint can be accelerated to flow back into the electrophoretic pool 37, thereby avoiding waste of the electrophoretic paint and avoiding pollution to the oven.
[0050] Reference Figure 5 and Figure 6 The scraping mechanism 5 includes a scraper 10 installed on the inner side of the guide frame 1, and both ends of the scraper 10 are slidably fitted with the inner wall of the guide frame 1, and an arc-shaped groove 19 is provided at the bottom of the scraper 10, and the lower end edge of the arc-shaped groove 19 is slidably fitted with the upper end surface of the guide plate 4. The bottom of the arc-shaped groove 19 and the guide plate 4 are arc-shaped, and the arc is bent downward. A track changing assembly 6 is provided between the two ends of the scraper 10 and the inner wall of the guide frame 1, and a toggle assembly 7 is provided at the top of both ends of the scraper 10. The arc-shaped guide plate 4 can make the electrophoretic paint converge in the middle depression of the guide plate 4, thereby preventing the electrophoretic paint from flowing on a large scale on the upper surface of the guide plate 4.

[0053] Reference Figure 3 and Figure 6 The transmission assembly 9 includes two symmetrically distributed slide rail grooves opened in the guide frame 1, and a threaded slider 12 is slidably embedded in the slide rail groove. The top of the threaded slider 12 is fixedly embedded in the limit plate 20. A cavity 14 is opened inside the end of the guide frame 1 away from the open port. A reciprocating screw 11 is rotatably installed inside the guide frame 1, and the threaded slider 12 is threadedly sleeved on the outer surface of the reciprocating screw 11. The reciprocating screw 11 is rotatably embedded in the cavity 14. A motor 15 is fixedly installed inside the cavity 14, and a transmission belt 17 is installed on the output end of the motor 15 and the outer surface of the reciprocating screw 11 through a gear 16. When the motor 15 drives the reciprocating screw 11 to make the threaded slider 12 move back and forth, the scraper 10 is reciprocated.
[0054] Reference Figure 4 and Figure 6The air supply mechanism 8 includes a rotating shaft 13 that is rotatably embedded in the interior of each column 2, wherein the bottoms of the two rotating shafts 13 are rotatably embedded in the interior of the cavity 14, and two mutually meshing bevel gears 18 are provided between the bottom of the rotating shaft 13 and the reciprocating screw 11. The two bevel gears 18 are fixedly sleeved on the outer surfaces of the reciprocating screw 11 and the rotating shaft 13, and the tops of the two rotating shafts 13 on the same side are rotatably embedded in the interior of the mounting frame 3. The inner side of the mounting frame 3 is rotatably embedded with a number of connecting shafts 27 that are equidistantly distributed in a straight line, and the outer surfaces of the rotating shaft 13 and the connecting shaft 27 are fixedly sleeved with gear 28, and a number of gears 2 The external transmission of 28 is installed with a transmission belt 29, and a protective frame 26 is fixedly installed on the bottom of the mounting frame plate 3, and a blade wheel 31 is rotatably embedded on the inner side of the bottom of the protective frame 26. The upper part of the blade wheel 31 and the bottom of the connecting shaft 27 are rotatably connected by a universal coupling 30. The bottom of the protective frame 26 is fixed with a mesh cover wrapped around the outside of the blade wheel 31. The connecting shaft 27 and the blade wheel 31 are connected by a universal coupling 30, which can make the air supply direction of the blade wheel 31 obliquely downward and supply air to the middle position of the automotive accessories. Under the blowing of the wind, the dripping speed of the electrophoretic paint hung on the surface of the automotive accessories can be accelerated.
[0055] The working process and effects of this embodiment are as follows: driven by the lifting structure, the auto parts inside the electrophoretic pool 37 are lifted and then transported to the interior of the oven. At this time, when the auto parts enter the interior of the oven, they are moved to the upper part of the guide plate 4. After leaving the electrophoretic pool 37, the electrophoretic paint will continuously drip from the surface of the auto parts. The dripping electrophoretic paint is received by the guide plate 4 and, under the action of the guide plate 4, flows into the electrophoretic pool 37, thereby recovering the electrophoretic paint while avoiding contamination of the interior of the oven.
[0056] Driven by the motor 15, the threaded slider 12 can move the scraper 10 through the limit plate 20 and the connecting rod 22. The scraper 10 can achieve reciprocating movement of the bottom of the scraper 10 against the upper end surface of the guide plate 4 when the threaded slider 12 moves back and forth through the positioning column 24 whose ends are engaged with the groove rail 1 32 and the groove rail 2 33. The purpose of reciprocating movement of the scraper 10 is to accelerate the sliding speed of the electrophoretic paint adhered to the upper part of the guide plate 4. Because when the oven performs a curing process on automobile parts, it is first pre-cured, that is, preheated at a low temperature, and then cured at a high temperature, so that the electrophoretic paint quickly flows back into the electrophoretic pool 37, which can prevent a large amount of electrophoretic paint from condensing due to excessive temperature and solidifying on the upper part of the guide plate 4, causing waste;
[0057] During the driving process, the motor 15 can also simultaneously drive the rotating shaft 13, the second gear 28 and the second transmission belt 29, so that the blade wheels 31 arranged in two rows can supply air to the automotive parts in a staggered manner. Since the upper temperature is generally higher than the lower temperature when the oven is preheated, the air supplied by the blade wheel 31 can make the entire automotive part receive a uniform hot air flow for preheating treatment. Moreover, under the blowing of the wind, the dripping of the electrophoretic paint hung on the shower can be accelerated, thereby improving the recycling efficiency.
[0058] Example 2
[0059] Based on the electrophoretic paint treatment device for automotive parts provided in the first embodiment of this application, the second embodiment of this application provides another electrophoretic paint treatment device for automotive parts. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.
[0060] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and implementation plans.

A gauze filter cloth 41 is fitted on the lower bottom of the interior of the semicircular bottom filter frame 40. Both ends of the gauze filter cloth 41 extend to the bottom of the interior of the collection cavity, and the gauze filter cloth 41 is fixed to the bottom of the collection cavity. The two ends of the extended filter cloth 41 are fixedly connected, and buckles for limiting the fit between the gauze filter cloth 41 and the semicircular bottom filter frame 40 are fixedly installed on the left and right sides of the inner wall of the semicircular bottom filter frame 40. The two edges of the gauze filter cloth 41 are slidably engaged between the buckles and the semicircular bottom filter frame 40. A driving component is provided between the bottom of the gauze filter cloth 41 and the collecting frame 38. Due to the chemical reaction during electrophoretic treatment and the curing of the electrophoretic paint in the oven, there will be more impurities in the electrophoretic paint. The semicircular bottom filter frame 40 can isolate the impurities and allow the filtered electrophoretic paint to flow into the electrophoretic tank 37 for continued use.

The two rollers 42 are fixedly sleeved with a gear three 44 at one end close to the guide frame 1, and the two gears three 44 are movably engaged. A touch assembly is provided between one of the rollers 42 and the limit plate 20. When the two rubber friction wheels 43 clamp the gauze filter cloth 41 and rotate synchronously in opposite directions, the gauze filter cloth 41 can be moved, and the end to end of the gauze filter cloth 41 is butted together to form a ring, that is, the gauze filter cloth 41 can circulate inside the collecting frame 38 and the semicircular bottom filter frame 40.
[0063] Reference Figure 10 and Figure 11 The trigger assembly includes a movable ratchet 48 fixedly sleeved on the outside of one of the rollers 42, and the outer diameter of the movable ratchet 48 is larger than the outer diameter of the gear three 44. The outer side of the movable ratchet 48 is engaged with a rack 46 that fits the side wall of the collection frame 38. The bottom of the rack 46 is slidably embedded with a limit block 45 fixedly installed on the side wall of the collection frame 38, and a spring three 47 is fixedly installed between the top of the limit block 45 and the rack 46. The top of the rack 46 is elastically rotated by the coil spring and the rotating rod with a push rod 49. The end of the rack 46 away from the collection frame 38 A limit plate 52 is fixedly installed to limit the push rod 49. A bracket 50 is provided at the bottom of the guide frame 1, and both ends of the bracket 50 are fixedly connected to the limit plate 20 through a connecting arm. A clamping block 51 is fixedly sleeved on the outer surface of the bracket 50. Every time the scraper 10 slides obliquely downward, the push rod 49 can be pushed by the clamping block 51, so that the rack 46 slides downward. At this time, the two rubber friction wheels 43 can clamp and transmit the gauze filter cloth 41. During the movement, the annular gauze filter cloth 41 can clean out solid impurities deposited at the bottom of the semicircular bottom filter frame 40.
[0064] Reference Figure 12 Bent rubber strips 54 are fixedly installed on the two side edges of the gauze filter cloth 41, and a number of equally distributed supporting strips 53 are fixedly installed on the upper part of the gauze filter cloth 41. The design of the bent rubber strips 54 can increase the friction between the gauze filter cloth 41 and the rubber friction wheel 43. At the same time, through the action of the supporting strips 53, during the movement of the gauze filter cloth 41, the supporting strips 53 can lift up impurities and discharge them to the outside of the electrostatic tank 37.
[0065] The working principle of this embodiment is as follows: when the refluxed electrophoretic paint enters the electrophoretic tank 37, it will first enter the interior of the semi-circular bottom filter frame 40. Because impurities or sediments are easily generated in the electrophoretic paint during the electrophoretic processing in the electrophoretic tank 37, such substances will be dripped onto the surface of the automotive parts along with the electrophoretic paint. At this time, during the recycling process, the semi-circular bottom filter frame 40 can just filter the recycled electrophoretic paint once to separate the impurities and sediments. In the process of reciprocating movement, the two limit plates 20 can push the push rod 49 downward once through the block 51. Figure 11 In the figure, the top of the push rod 49 is in contact with the block 51. When the block 51 pushes the push rod 49, the rack 46 can slide down, and the spring three 47 is compressed. During the downward movement of the rack 46, the active ratchet 48 can be rotated by meshing with the active ratchet 48. At this time, the two rubber friction wheels 43 can clamp the mesh filter cloth 41 for transmission through the two meshing gears three 44. When the block 51 is reset, the rack 46 will move upward under the action of the spring three 47. At this time, the rack 46 moves upward and will not drive the active ratchet 48 to rotate. The bevel teeth of the active ratchet 48 will be retracted. The active ratchet 48 is a prior art.
[0066] During the transmission process, the gauze filter cloth 41 can remove impurities or sediments deposited inside the semicircular bottom filter frame 40 through the support bar 53, and under the action of the circular transmission, the sediments or impurities fall into the inside of the collection frame 38, which can achieve the filtration and impurity removal of the recovered electrophoretic paint;
[0067] It is worth noting that the gauze filter cloth 41 gradually flattens out from the arc-shaped state. When flattening, the gauze filter cloth 41 will undergo obvious deformation, and the deformation process can cause the attached inverted sediment to fall.
