The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0023] Reference Figure 1 and Figure 2A device for precisely controlling the coating thickness of plastic parts includes a base 10, with upright plates 20 fixedly connected to both sides of the outer wall of the base 10, and a plastic part body 30 disposed on the top of the base 10; wherein, the base 10 and the two upright plates 20 together constitute the main supporting body of the device, providing an installation platform for the clamping component 40 and the driving component 50.
[0024] The clamping assembly 40 includes a fixing rod 401, which passes through one side of the upright plate 20 and is rotatably connected to the upright plate 20. The fixing rod 401 needs to have a certain length so as to be fixedly connected to the second bevel gear 504 and realize the connection with the drive assembly 50.
[0025] And the drive assembly 50 includes a second bevel gear 504 fixedly connected to the outer wall of the fixed rod 401; the second bevel gear 504 is the core structure that connects the clamping assembly 40 and the drive assembly 50, and can convert the driving force of the motor 502 into the power to rotate the plastic part.
[0026] Specifically, the clamping assembly 40 also includes a first threaded rod 402, which is threaded to the inner wall of the fixed rod 401. The end of the first threaded rod 402 is attached to one side of the outer wall of the plastic part body 30, and a second threaded rod 403 is provided on the other side of the outer wall of the plastic part body 30. Furthermore, a rotating rod 404 is threaded to the outer wall of the second threaded rod 403, and the outer wall of the rotating rod 404 is fixedly connected to the outer wall of the upright plate 20. The first threaded rod 402 and the second threaded rod 403 are respectively provided on the inner walls of the fixed rod 401 and the rotating rod 404, so that they can be adjusted according to the size of the plastic part body 30. At the same time, a rubber disc or other disc with a certain friction force can be provided at the end of the threaded rod to increase the clamping effect on the plastic part.
[0027] Reference Figure 1 , Figure 2 and Figure 3 The drive assembly 50 also includes a mounting plate 501 fixedly connected to the outer wall of the upright plate 20. A motor 502 is fixedly mounted on the top wall of the mounting plate 501. A first bevel gear 503 is fixedly connected to the output end of the motor 502. The first bevel gear 503 and the second bevel gear 504 are meshed together. The mounting plate 501 supports the motor 502, and the motor 502 provides power input to the drive assembly 50 to achieve the meshing effect of the first bevel gear 503 and the second bevel gear 504.
[0028] Reference Figure 1A mounting base 80 is fixedly connected to the center of the outer wall of the base 10, and a collection chamber 70 is fixedly connected to the outer wall of the mounting base 80. The mounting base 80 is installed at the center of the top wall of the base 10, and together with the semi-circular collection chamber 70, it can collect the dripping paint during the spraying process, ensuring the cleanliness of the working environment.
[0029] Specifically, a control panel 60 is fixedly connected to the outer wall of the upright plate 20, and the control panel 60 is electrically connected to the motor 502; wherein, the control panel 60 centrally controls the motor 502 and other electrical structures, thereby ensuring the stability of the device operation and the convenience of use.
[0030] Working principle: First, the plastic part body 30 to be sprayed is placed on the adjacent sides of the two upright plates 20. The two upright plates 20 are supported by the base 10 to achieve the overall load-bearing effect of the device. At this time, the first threaded rod 402 is screwed on. Since the fixed rod 401 is only rotatably connected to the upright plate 20 and its position does not change, the first threaded rod 402 will move horizontally along the inner wall of the fixed rod 401 when it rotates, so that the end of the first threaded rod 402 contacts the outer wall of the plastic part body 30. Positioning is performed on one side of the outer wall of the plastic part body 30. Similarly, the second threaded rod 403 is screwed on. The second threaded rod 403 is threaded to the inner wall of the rotating rod 404. The rotating rod 404, like the fixed rod 401, only has the effect of rotating in place. After being screwed, the second threaded rod 403 moves horizontally along the inner wall of the rotating rod 404 until its end contacts the outer surface of the plastic part body 30, thereby achieving overall clamping of the plastic part body 30 and meeting the clamping effect of plastic parts of different sizes.
[0031] When the spraying machine sprays the outer surface of the plastic part body 30, the motor 502 is started. The motor 502 drives the first bevel gear 503 to rotate. The first bevel gear 503 rotates under the drive of the motor 502, thereby driving the second bevel gear 504 to rotate synchronously. Since the second bevel gear 504 is fixedly connected to the fixed rod 401, it drives the fixed rod 401 to rotate synchronously. This causes the entire clamping assembly 40 and the plastic part body 30 to rotate synchronously. By controlling the rotation speed of the plastic part body 30, the coating thickness of the plastic part can be adjusted. With the help of the collection chamber 70, the paint dripping from the sprayed plastic part body 30 can be collected to avoid pollution to the working environment and improve the practicality of the device.
[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
