Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, specifically a surface spraying device for casting processing. Background Technology

[0002] In existing casting painting processes, cranes are commonly used to lift the workpieces, which remain stationary. Workers then need to hold spray guns and move around the workpieces while spraying.

[0003] Existing spraying methods have many drawbacks: First, because workers cannot maintain a stable spraying distance and angle while moving, the spraying stability is poor, which seriously affects the uniformity of the coating. Second, workers walk around the workpiece while spraying, resulting in low operating efficiency and extremely high labor intensity. Third, in order to avoid affecting workers' operations, the exhaust vents of the paint mist dust removal system in the spraying area can only be installed far away from the workpiece, which makes its effect of collecting and controlling the spread of paint mist poor. This not only pollutes the working environment but may also affect the health of operators. At the same time, the spread of a large amount of paint mist also leads to the waste of paint.

[0021] The alternating feeding mechanism 4 includes a connecting plate 41, a mounting plate 42, an electric push rod 43, a moving block 44, a toothed plate 45, a gear 46, a first rotating shaft 47, a rotating plate 48, a second motor 49, a second rotating shaft 410, and a hanging plate 411. The connecting plate 41 is vertically fixedly connected to the moving plate 36. The front end of the connecting plate 41 is fixedly connected to the mounting plate 42. The electric push rod 43 is fixedly connected to the mounting plate 42. The output end of the electric push rod 43 is fixedly connected to the moving block 44. The moving block 44 is slidably connected to the mounting plate 42. A toothed plate 45 is fixedly connected to one side of the moving block 44. A gear 46 is meshed with one side of 45. A first rotating shaft 47 is fixedly connected inside the gear 46. The first rotating shaft 47 is rotatably connected to the mounting plate 42 through a bearing. The lower end of the first rotating shaft 47 passes through the mounting plate 42 and is fixedly connected to a rotating plate 48. A second motor 49, a second rotating shaft 410, and a hanging plate 411 are symmetrically arranged on both sides of the rotating plate 48. The second motor 49 is fixedly connected to the top surface of the rotating plate 48. The output end of the second motor 49 is fixedly connected to the second rotating shaft 410. The lower end of the second rotating shaft 410 is fixedly connected to the hanging plate 411. A hanging groove 412 is provided on the hanging plate 411.

[0022] During operation, a hanger 61 is installed on the workpiece 6. The workpiece 6 can be suspended in the hanging groove 412 on the hanging plate 411 by the hanger 61. The hanger 61 is engaged in the hanging groove 412, and then the height can be adjusted and sprayed.

[0023] The paint mist collection mechanism 5 includes a collection hood 51, a paint mist treatment component 52, and a negative pressure fan 53. The collection hood 51 is connected to the paint mist treatment component 52 through a pipe, and the paint mist treatment component 52 is connected to the negative pressure fan 53 through a pipe. The paint mist treatment component 52 includes a treatment box 521, a filter layer 522, an adsorption layer 523, and a purification layer 524. The filter layer 522, the adsorption layer 523, and the purification layer 524 are detachably connected inside the treatment box 521.

[0024] The working principle of this utility model is as follows: First, the workpiece 6 is assembled with the hanger 61, and then the hanger 61 is inserted into the hanging groove 412 of the hanging plate 411. The hanging groove 412 limits the hanger 61, so that the workpiece 6 is stably suspended. The two hanging plates 411 can simultaneously hang the workpieces to be sprayed. Then, the spraying height can be adjusted by the lifting mechanism 3. The first motor 32 is started, and the first motor 32 drives the lead screw 31 to rotate. The lead screw 31 drives the moving plate 36 to rise and fall smoothly. Then, through the connecting plate 41, the mounting plate 42, etc., the hanging plate 411 and the workpiece 6 are adjusted to a height position suitable for the spraying equipment. Then, the spraying operation is carried out. During the spraying process, the second motor 49 is started. The second motor 49 drives the second rotating shaft 410 to rotate, which drives the hanging plate 411 and the hung workpiece 6 to rotate at a uniform speed, so that the surface of the workpiece 6 is evenly exposed to the spraying equipment, ensuring the spraying coverage. The coating process is comprehensive and uniform in thickness. During the spraying process, the negative pressure fan 53 operates continuously, generating negative pressure to draw the paint mist generated during spraying into the collection hood 51. The mist is then transported through a pipeline to the paint mist treatment component 52. The paint mist first passes through the filter layer 522 to intercept large paint particles, then through the adsorption layer 523 to adsorb volatile organic compounds, and finally through the purification layer 524 for deep purification before being discharged after meeting the standards. After the workpiece is sprayed, the workpiece to be sprayed is transported to the spraying station by the alternating feeding mechanism 4, and the sprayed workpiece is transported to the loading and unloading station. The electric push rod 43 is activated, which pushes the moving block 44 to slide along the mounting plate 42. The toothed plate 45 moves with the moving block 44 and meshes with the gear 46, driving the first rotating shaft 47 to rotate, causing the rotating plate 48 to rotate 180°, completing the alternation of the two hanging plates 411, allowing the workpiece to be sprayed to move to the spraying station and continue the spraying operation. This process is repeated.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
