[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings. Example 1
[0027] like Figure 1-5 As shown, this utility model provides a technical solution: a spraying device for plastic parts, including a spraying box 1, a conveying device 2 installed inside the spraying box 1, a material box 4 fixedly installed on the upper part of the spraying box 1, a material pump 5 fixedly installed on the upper part of the spraying box 1, and a connecting assembly 3 disposed on one side of the spraying box 1. The connecting assembly 3 includes a stirring mechanism 31 disposed on the upper part of the spraying box 1. An adjusting mechanism 32 is disposed inside the spraying box 1. The stirring mechanism 31 includes a box cover 311 fixedly installed on the upper part of the material box 4. A first motor 312 is fixedly installed on the upper part of the box cover 311 by a mounting bracket. A first rotating shaft 313 is fixedly connected to the output end of the first motor 312. A mounting sleeve 314 is sleeved on the outside of the first rotating shaft 313. A sliding groove 311 is formed on the outer wall of the first rotating shaft 313. 3. A sliding rod 3114 is fixedly connected to the inner wall of the chute 3113, and a slider 3115 is slidably connected to the outer wall of the sliding rod 3114. A first spring 3116 is fixedly connected to the inner wall of the chute 3113. A stirring rod 315 is fixedly connected to the outer wall of the mounting sleeve 314. A inclined pressing ring 316 is fixedly connected to the bottom of the box cover 311. A pressing rod 317 is fixedly connected to the outer wall of the mounting sleeve 314 via a rotating rod. A ball is movably connected to the top of the pressing rod 317. An installation rod 318 is fixedly connected to the outer wall of the bottom end of the first rotating shaft 313. A second rotating shaft 319 is rotatably connected to one end of the installation rod 318 via a bearing. A conveying blade 3110 is fixedly connected to the outer wall of the second rotating shaft 319. A gear 3111 is fixedly connected to the bottom end of the second rotating shaft 319. A toothed ring 3112 is fixedly connected to the inner wall of the material box 4.
[0028] In this embodiment, the first rotating shaft 313 is rotatably connected to the box cover 311 via a bearing, the outer side of the slider 3115 is fixedly connected to the mounting sleeve 314, and one end of the first spring 3116 is fixedly connected to the slider 3115. Through the cooperation of the box cover 311, the first motor 312, the first rotating shaft 313, the mounting sleeve 314, the stirring rod 315, the inclined pressing ring 316, the pressing rod 317, the mounting rod 318, the second rotating shaft 319, the conveying blade 3110, the gear 3111, the gear ring 3112, the slide groove 3113, the slide rod 3114, the slider 3115, and the first spring 3116, the paint in the material box 4 can be effectively stirred, which can prevent the paint from settling. This can prevent the settled paint from being transported into the spray gun 3211, causing the spray gun 3211 to be blocked and affecting subsequent use.
[0029] Furthermore, gear 3111 is meshed with gear ring 3112.
[0030] In use, the device drives the first rotating shaft 313 to rotate via the first motor 312. Under the limiting action of the sliding rod 3114 and the slider 3115, the mounting sleeve 314, which is fixedly connected to the outside of the slider 3115, drives the stirring rod 315 to rotate synchronously, thereby initially stirring the paint in the material box 4. Furthermore, when the mounting sleeve 314 rotates, the pressing rod 317 drives the ball bearings to rotate synchronously. Under the action of the first spring 3116, the pressing rod 317 drives the ball bearings to slide relative to the inclined pressing ring 316, thereby allowing the stirring rod 315 to rotate. During operation, the device reciprocates up and down, effectively mixing the paint in the material box 4 and preventing sedimentation that could affect subsequent use. Furthermore, when the first rotating shaft 313 rotates, the mounting rod 318 drives the second rotating shaft 319 to rotate synchronously. Due to the meshing of the gear 3111 and the gear ring 3112, the conveying blade 3110, which is fixedly connected to the outer wall of the second rotating shaft 319, rotates on its own axis while revolving around the central axis, thereby conveying the material at the bottom of the material box 4 upwards. This further prevents paint sedimentation and increases the applicability of the device. Example 2
[0031] Based on Embodiment 1, a preferred embodiment of the spraying apparatus for plastic parts provided by this utility model is as follows: Figures 1 to 5As shown: The adjustment mechanism 32 includes an electric telescopic rod 321 fixedly installed inside the spray box 1. The output end of the electric telescopic rod 321 is fixedly connected to a mounting plate 322. A second motor 323 is fixedly installed at the front of the mounting plate 322 via a support. A lead screw 324 is fixedly connected to the output end of the second motor 323. A movable hole 325 is opened in the middle of the mounting plate 322. A movable block 326 is slidably connected to the inner wall of the movable hole 325. A connecting plate 327 is fixedly connected to the bottom of the movable block 326. A slide rail 328 is fixedly connected to the bottom of the mounting plate 322. A spraying device 329 is fixedly installed at the bottom of the connecting plate 327. A spray gun 3211 is connected to the lower part of the spraying device 329. A feed pipe 3210 is connected to one side of the spraying device 329.
[0032] In this embodiment, the lead screw 324 is rotatably connected to the mounting plate 322 via a bearing, and the movable block 326 is threadedly connected to the outer wall of the lead screw 324. Through the cooperation of the electric telescopic rod 321, the mounting plate 322, the second motor 323, the lead screw 324, the movable hole 325, the movable block 326, the connecting plate 327, the slide rail 328, the spraying device 329, the feed pipe 3210, and the spray gun 3211, the positions of the spraying device 329 and the spray gun 3211 can be adjusted, thereby enabling spraying operations on different positions of the workpiece and increasing the applicability of the device.
[0033] Furthermore, the feed pipe 3210 is connected to the output end of the feed pump 5, and the input end of the feed pump 5 is connected to the material box 4 through a connecting pipe. The connecting plate 327 is slidably connected to the outer wall of the slide rail 328.
[0034] When plastic parts need to be sprayed, the plastic parts can be conveyed by the conveying device 2. When the plastic parts are conveyed to the lower part of the spraying device 329, the mounting plate 322 is moved downward by the electric telescopic rod 321, so that the spraying device 329 and the spray gun 3211 can move downward synchronously. Then, the paint in the material box 4 can be conveyed into the spraying device 329 by the material pump 5. Then, the spray gun 3211 can be used to spray the workpiece. The second motor 323 drives the lead screw 324 to rotate, so that the movable block 326 threaded to the outer wall of the lead screw 324 can drive the connecting plate 327 to move, so that the position of the spraying device 329 can be adjusted, and spraying operations can be performed on different positions of the workpiece, further increasing the applicability of the device.
