Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0030] In one embodiment of this utility model, such as Figures 1-2As shown, a paint spraying device for plastic products is provided, including a base 1, a stand 2, a drive mechanism 3, a lifting mechanism 4 and a spraying mechanism 5. The stand 2 is fixedly connected to one side of the base 1. The drive mechanism 3 is connected to the base 1 and the stand 2 respectively, and is connected to the lifting mechanism 4. The spraying mechanism 5 is connected to the lifting mechanism 4.

[0031] The drive mechanism 3 includes a motor base 31, a servo motor 32, a drive pulley 33, a drive belt 34, and a driven pulley 35. The motor base 31 is fixedly connected to the base 1, and the servo motor 32 is fixedly connected to the motor base 31. The drive pulley 33 is connected to the servo motor 32, and the drive belt 34 is fixedly wound around the drive pulley 33 and the driven pulley 35 respectively. The driven pulley 35 is rotatably connected to the stand 2 and connected to the lifting mechanism 4. The servo motor 32 drives the drive pulley 33 to rotate, and then the drive belt 34 drives the driven pulley 35 to rotate, thereby providing power to the lifting mechanism 4.

[0032] The lifting mechanism 4 includes a lead screw 41, a nut 42, and a slide 43. The lead screw 41 is rotatably connected to the stand 2 and fixedly connected to the driven pulley 35. The nut 42 is threadedly connected to the lead screw 41 and fixedly connected to the slide 43. The slide 43 is movably disposed within the stand 2. When the driven pulley 35 rotates, it drives the lead screw 41 to rotate. Since the nut 42 is threadedly connected to the lead screw 41, the nut 42 will make linear motion on the lead screw 41, thereby driving the slide 43 to slide within the stand 2, realizing the lifting and adjusting of the spraying mechanism 5.

[0033] The spraying mechanism 5 includes a fixed frame 51, a feed pipe 52, a spray pump 53, and a nozzle 54. One end of the fixed frame 51 is fixedly connected to the slide 43, and the other end is fixedly connected to the feed pipe 52. The spray pump 53 is fixedly connected to the feed pipe 52, and the nozzle 54 is fixedly connected to the spray pump 53. The spray pump 53 delivers paint from the feed pipe 52 to the nozzle 54, thereby achieving spraying of the surface of the plastic product.

[0034] The plastic product surface paint spraying device provided in this application uses a servo motor 32 to drive pulleys and belts, which in turn drive the lead screw 41 and nut 42 to achieve the lifting and lowering of the spraying mechanism 5. The operation is simple and easy to understand, reducing the technical requirements for operators. Through a precise lifting adjustment mechanism, the position of the nozzle 54 can be flexibly adjusted according to the different heights and shapes of the plastic products to achieve a uniform spraying effect and improve the appearance quality of the plastic products.

[0035] In another embodiment of this utility model, the base 1 is L-shaped, and two fixing bolts 11 are provided at the bottom of the base 1, which are arranged in parallel and opposite directions. The L-shaped base 1 design can increase the stability of the device, and the fixing bolts 11 can firmly fix the device to the workbench to prevent the device from shaking during operation.

[0036] In another embodiment of this utility model, a groove 21 is provided in the support 2, and the slide 43 is movably disposed in the groove 21 and fixedly connected to the nut 42. The groove 21 can provide guidance for the sliding of the slide 43, ensuring that the slide 43 slides smoothly in the support 2 and improving the accuracy of the lifting of the spraying mechanism 5.

[0037] In another embodiment of this utility model, the fixing frame 51 is L-shaped, with one end of the fixing frame 51 fixedly connected to the slide 43 and the other end fixedly connected to the material conveying pipe 52. The L-shaped fixing frame 51 can reasonably arrange the spraying mechanism 5, so that the spray nozzle 54 can accurately aim at the plastic product for spraying.

[0038] In another embodiment of this utility model, the driving pulley 33 is disposed on one side of the driven pulley 35, and the driving pulley 33 and the driven pulley 35 are arranged parallel to each other.

[0039] In another embodiment of this utility model, a stop valve 55 is provided on the feed pipe 52. The stop valve 55 is fixedly connected to the feed pipe 52 and is located on one side of the spray pump 53. The stop valve 55 can control the flow of paint. When it is necessary to stop spraying, the stop valve 55 is closed to prevent paint from continuing to flow out, thus avoiding paint waste and environmental pollution.

[0040] When using the spraying device provided in this application, the plastic product to be sprayed is first placed in a suitable position on the device. The servo motor 32 is started, which drives the drive pulley 33 to rotate. The drive pulley 33 drives the driven pulley 35 to rotate via the drive belt 34. The driven pulley 35 drives the lead screw 41 to rotate. Since the nut 42 is threadedly connected to the lead screw 41, the nut 42 will make linear motion on the lead screw 41, thereby driving the slide 43 to slide in the slide groove 21 in the stand 2, realizing the lifting and lowering adjustment of the spraying mechanism 5, so that the nozzle 54 is adjusted to a suitable spraying height.

[0041] The spray pump 53 is turned on to deliver paint to the spray head 54. According to the spraying requirements, the stop valve 55 is opened, allowing paint to be sprayed from the spray head 54 to coat the surface of the plastic product. During the spraying process, the lifting position of the spraying mechanism 5 can be further adjusted by controlling the rotation direction and speed of the servo motor 32 to ensure uniform spraying. After spraying is completed, the stop valve 55 is closed to stop the paint delivery and prevent paint dripping.

[0042] The plastic product surface paint spraying device provided in this application uses a servo motor 32 to drive pulleys and belts, which in turn drive the lead screw 41 and nut 42 to achieve the lifting and lowering of the spraying mechanism 5. The operation is simple and easy to understand, reducing the technical requirements for operators. Through a precise lifting adjustment mechanism, the position of the nozzle 54 can be flexibly adjusted according to the different heights and shapes of the plastic products to achieve a uniform spraying effect and improve the appearance quality of the plastic products.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
