It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0034] In one embodiment of the present invention, see Figure 1 The dust-proof device of the coating machine comprises a support plate 2 arranged on a coating machine body 1, and support slide frames 3 are symmetrically and slidably provided on both sides of the support plate 2, and a protective cover 4 is connected to the support slide frame 3, and a limiting component is provided between the support slide frame 3 and the support plate 2, and a cross plate 5 is slidably provided at the end of the protective cover 4, and a pull plate 7 is connected to one end of the cross plate 5, and a positioning component is provided between the pull plate 7 and the protective cover 4, and baffles 6 that are symmetrically and movably provided on the cross plate 5 and contact the top of the protective cover 4 and the support plate 2 respectively, and an elastic component is provided between the cross plate 5 and the baffle 6.

[0035] In this embodiment, the position of the supporting sliding frame 3 can be quickly positioned through the limiting component, so that the position of the protective cover 4 can be fixed, and the stable dustproof of the protective cover 4 can be achieved. The position of the cross plate 5 can be fixed through the positioning component. Through the elastic component, the cross plate 5 cooperates with the baffle 6 to block the two ends of the protective cover 4 to prevent external dust from entering the coating area, thereby improving the cleaning effect. It has the effects of fast positioning, stable dustproof, convenient operation, comprehensive shielding, efficient dustproof, reliable structure and simple and practical.

[0036] In one embodiment of the present invention, see Figure 1 , Figure 2 and Figure 3 The limiting assembly includes a side groove 10 arranged on one side of the support plate 2, a limiting hole 11 is arranged at the bottom of the side groove 10, a connecting hole 12 corresponding to the limiting hole 11 is arranged at the bottom of the support slide frame 3, a through groove 15 is arranged on the support slide frame 3, a vertical rod 16 is installed in the through groove 15, a lifting rod 14 is slidably arranged on the vertical rod 16, and a limiting rod 13 movably matched with the limiting hole 11 and the connecting hole 12 is connected to the end of the lifting rod 14 close to the side groove 10, and an adjusting module movably matched with the lifting rod 14 is arranged on the outer side of the support slide frame 3;

[0037] The adjustment module includes a rotating plate 17, one end of which is rotatably connected to the supporting slide frame 3 through a rotating shaft, the rotating plate 17 is provided with a sliding groove 19 that slides with the lifting rod 14, the outer end of the rotating plate 17 is connected to a handle 18, the supporting slide frame 3 is provided with a fixed block 21, and a spring 20 is connected between the outer end of the rotating plate 17 and the fixed block 21.

[0038] In this embodiment, in the initial state, the limiting rod 13 cooperates with the limiting hole 11 and the connecting hole 12 respectively, the lifting rod 14 is located at one end of the through slot 15 close to the limiting hole 11, and the spring 120 is at its original length. At this time, the positions of the supporting slide frame 3 and the protective cover 4 are fixed, and the coating machine body 1 can be effectively dustproof. When it is necessary to push the protective cover 4, the handle 18 drives the rotating plate 17 to rotate upward around the rotating axis. In the process of rotating the rotating plate 17 to the horizontal state, the spring 120 is stressed and contracts, and the rotating plate 17 drives the lifting rod 14 along the sliding groove 19 by slidingly cooperating with the lifting rod 14. As the vertical rod 16 moves upward, during the process of the rotating plate 17 rotating upward from the horizontal state, the spring 20 restores its original length, and the lifting rod 14 moves to the end of the vertical rod 16 away from the connecting hole 12. The lifting rod 14 releases the connection between the limiting rod 13 and the limiting hole 11 and the connecting hole 12 by driving the limiting rod 13 to move upward, thereby releasing the fixation of the position of the support slide frame 3, and the support slide frame 3 is in an active state, which facilitates the movement of the position of the support slide frame 3 and the protective cover 4. The support slide frame 3 is set as a C-shaped frame, and the connecting line of the rotating shaft and the fixed block 21 is perpendicular to the vertical rod 16 and is located in the middle of the vertical rod 16.

[0040] In this embodiment, the pull plate 7 can be positioned by the positioning groove 8 and the positioning turn buckle 9. The pull plate 7 can be quickly released by rotating the positioning turn buckle 9, which facilitates the rapid withdrawal of the cross plate 5. The positioning turn buckle 9 is configured as a cam.

[0041] In one embodiment of the present invention, see Figure 1 and Figure 4 The elastic component includes a receiving groove 22 arranged inside the horizontal plate 5, and a sliding bar 23 is symmetrically and slidably arranged inside the horizontal plate 5 in the receiving groove 22. The sides of the sliding bars 23 that are away from each other are respectively connected to the corresponding baffles 6, and a spring 24 is connected between the sliding bars 23.

[0042] In this embodiment, spring 24 can be used to push the symmetrically arranged sliding bars 23 away from each other, and the sliding bars 23 drive the baffle 6 to move synchronously. The cross plate 5 cooperates with the baffle 6 to fully block the end of the protective cover 4 to prevent external dust from entering the inside of the protective cover 4, wherein the length of the baffle 6 is consistent with the length of the inner space of the protective cover 4.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
