Description

Technical Field

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

[0002] A surface uniform spraying equipment for plastic parts processing is a device specifically designed to apply a coating to the surface of plastic parts. Its main function is to uniformly disperse and spray the coating onto the surface of the plastic parts, so that the plastic parts achieve the desired appearance.

[0003] Announcement No. CN221268616U discloses a surface spraying device for automotive plastic parts, including a base plate and a top plate. The top plate is disposed on the upper end of the base plate and connected to it through a support plate. The support plate is provided with a clamping assembly for clamping the workpiece. The clamping assembly is located between the base plate and the top plate. In the field of plastic parts processing, surface uniform spraying equipment plays a crucial role. It aims to provide plastic parts with a high-quality, uniform and complete coating to meet various needs such as aesthetics and protection. However, many plastic parts often have complex surface structures during the design and manufacturing process. Among them, the situation where there are grooves on the surface and the grooves have slopes is particularly difficult. The spray gun spray shape, angle, and paint spray pressure and flow rate are difficult to adapt to the special geometry of the grooves and slopes. For example, when the spray gun is used on plastic parts with grooves and slopes according to the conventional spray trajectory and parameters, the paint often cannot accurately reach all corners of the grooves and slopes. Due to the obstruction and angle change of the grooves and slopes, paint particles may be blocked or scattered by the slopes during the spraying process, and cannot be evenly adhered to the slope surface.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5The present invention provides a technical solution: a uniform surface spraying device for processing plastic parts, including a base 1, a first support plate 2 fixedly connected to the upper end of the base 1, a spraying box 3 fixedly connected to the outside of the first support plate 2, a rotating mechanism 4 provided below the inner side of the first support plate 2, and a reciprocating mechanism 5 provided above the rotating mechanism 4.

[0022] The rotating mechanism 4 includes a second support plate 401 slidably connected to the lower inner side of the first support plate 2. A cylinder 402, fixedly connected to the base 1, is located below the spray box 3. The output end of the cylinder 402 is fixedly connected to the second support plate 401. A motor 403 is fixedly connected to the upper side of the second support plate 401. A threaded rod 404 is fixedly connected to the output end of the motor 403. A sliding plate 405, slidably connected to the second support plate 401, is threadedly connected to the outer side of the threaded rod 404. A gear 406 is rotatably connected to the upper end of the sliding plate 405. A rack 407, fixedly connected to the second support plate 401, meshes with the outer side of the gear 406. The lower end of the gear 406 is fixedly connected to... A rotating cylinder 409 is connected to the inside of the rotating cylinder 409, and a push plate 408 is fixedly connected to the inside of the rotating cylinder 409. The upper end of the support rod 412 has a spherical shape, and the outer surface of the support rod 412 is in contact with the inner surface of the first groove 411. The width of the push plate 408 is greater than the distance from the inner wall of the rotating cylinder 409 to the central axis of the first rotating rod 410, so that when the push plate 408 rotates, it can push the support rod 412 to swing. The inner side of the gear 406 is fixedly connected to the first rotating rod 410, and the lower part of the first rotating rod 410 is provided with a first groove 411. The inner side of the first groove 411 is provided with a support rod 412, and the lower end of the support rod 412 is fixedly connected to a spray gun 413.

[0023] The reciprocating mechanism 5 includes a third support plate 501 fixedly connected to the upper end of the slide plate 405. A first guide groove 502 is provided inside the third support plate 501. Point a is located on the outer side of the first guide groove 502 away from the first support plate 2, point b is located on the inner side of the first guide groove 502 away from the first support plate 2, point c is located on the outer side of the first guide groove 502 close to the first support plate 2, and point d is located on the inner side of the first guide groove 502 close to the first support plate 2. The height of point a of the first guide groove 502 is lower than the height of point b of the first guide groove 502. The height of point 502c in the first guide groove is higher than that of point 502d in the first guide groove, so that when the first guide rod 503 moves to point 502a and then moves back, it can move to the lower end of the first guide groove 502. When the first guide rod 503 moves to point 502c and then moves back, it can drive the upper inner side of the first guide groove 502. The inner side of the first guide groove 502 is provided with the first guide rod 503, and one end of the first guide rod 503 is fixedly connected to a sliding plate 504. The first rotating rod 410... A second rotating rod 505 is fixedly connected to the upper end. A reciprocating plate 506, which is laterally slidably connected to the third support plate 501, is provided at the upper end of the second rotating rod 505. A guide hole 507 is provided in the middle of the reciprocating plate 506. A second guide rod 508, fixedly connected to the second rotating rod 505, is provided inside the guide hole 507. The guide hole 507 has a straight external structure, and the guide hole 507 and the second guide rod 508 are fitted with a clearance fit, allowing the second guide rod 508 to move within the guide hole 507. The reciprocating plate 506 performs reciprocating motion. A sliding hole 509 is provided inside one end of the reciprocating plate 506. A slider 510 is provided inside the sliding hole 509. A brush 511 is fixedly connected to one end of the sliding plate 504. The width of the slider 510 near the first support plate 2 is greater than the width of the slider 510 away from the first support plate 2. The outer side of the slider 510 fits against the inner side of the sliding hole 509, so that the slider 510 will not wobble when it moves inside the sliding hole 509. The slider 510 moves out of the inner side of the sliding hole 509.

[0024] During spraying, the starting motor 403 rotates, driving the threaded rod 404 to rotate, which in turn causes the slide plate 405 to slide laterally, driving the gear 406 to move laterally. This causes the gear 406 to contact the rack 407, resulting in the gear 406 rotating and moving laterally. This, in turn, drives the rotating cylinder 409 and the push plate 408 to rotate. Because the width of the push plate 408 is greater than the distance from the inner wall of the rotating cylinder 409 to the central axis of the first rotating rod 410, and the upper end of the support rod 412 has a spherical shape, with its outer surface fitting against the inner surface of the first groove 411, the push plate 408 pushes the support rod 412 to swing, causing the angle of the spray gun 413 to change continuously. This allows for spraying the inner surface of the groove, resulting in a more uniform spray.

[0025] When gear 406 rotates, it drives the first rotating rod 410 to rotate, which in turn drives the second rotating rod 505, the first rotating rod 410, and the second guide rod 508 to rotate. Because the guide hole 507 has a straight-line shape and the guide hole 507 and the second guide rod 508 are in a clearance fit, the reciprocating plate 506 performs lateral reciprocating motion, causing the sliding hole 509 and the slider 510 to reciprocate, and causing the first guide rod 503 to reciprocate. Since the height of point 502a of the first guide groove is lower than the height of point 502b, and the height of point 502c is higher than the height of point 502d... This allows the first guide rod 503 to move to the lower end of the first guide groove 502 when it moves back from point 502a. When the first guide rod 503 moves back from point 502c, it can drive the upper inner side of the first guide groove 502. When the first guide rod 503 moves backward, it can drive the sliding plate 504 and the brush 511 to push the debris backward from below. When the first guide rod 503 moves forward, it can drive the sliding plate 504 and the brush 511 to move forward from above without moving the debris, thus maintaining a relatively good environment in the area to be sprayed.
