Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, specifically to a device for applying a corrosion-resistant coating to hardware parts. Background Technology

[0002] Corrosion-resistant coatings for hardware are coatings used to improve the corrosion resistance of hardware. They form a protective barrier on the surface of the hardware, isolating it from contact with corrosive media and thus extending its service life. Therefore, corrosion-resistant coating equipment is needed in the hardware manufacturing process.

[0003] Existing devices have some drawbacks in use. For example, traditional coating methods mostly use manual spraying, which has many shortcomings. Although manual spraying is flexible, it is difficult to ensure the uniformity of the coating. Although there are mechanical spraying devices in the existing technology, these devices are difficult to achieve good results for small hardware parts with complex shapes. The problems of spraying dead corners and over-spraying are particularly prominent in these devices. Utility Model Content

[0004] The purpose of this invention is to provide a corrosion-resistant coating device for hardware parts, which solves the problem that although manual spraying is flexible, it is difficult to ensure the uniformity of the coating.

[0005] This utility model provides the following technical solution: a corrosion-resistant coating device for hardware, including a processing frame, a roller is arranged inside the processing frame, rotating rods are fixedly connected to the outer walls on both sides of the roller, the ends of the two rotating rods are rotatably connected to the inner side wall of the processing frame, one of the rotating rods passes through the side wall of the processing frame and the end is provided with a driving component for driving the roller to rotate, and support frames are fixedly connected to the opposite outer walls on the top of the processing frame, and auxiliary spraying components for spraying coating are provided on the upper surfaces of the two support frames.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Example

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a corrosion-resistant coating device for hardware, including a processing frame 1, a roller 11 arranged inside the processing frame 1, and multiple perforations 111 arrayed on the roller 11. The perforations 111 prevent the accumulation of excessive spray liquid residue inside the device, facilitating cleaning. Rotating rods 12 are fixedly connected to the outer walls on both sides of the roller 11. The ends of both rotating rods 12 are rotatably connected to the inner wall of the processing frame 1. One of the rotating rods 12 passes through the side wall of the processing frame 1 and its end is provided with a driving component 2 for driving the roller 11 to rotate. The top of the processing frame 1... Support frames 13 are fixedly connected to the outer walls of the two opposite sides of the part. The upper surfaces of the two support frames 13 are provided with auxiliary spraying components 3 for spraying paint. In actual use, the hardware to be sprayed is placed in the roller 11, and then the roller 11 on the rotating rod 12 is rotated by the drive component 2, so that the hardware rolls in the roller 11. While the roller 11 is rotating, the auxiliary spraying component 3 starts to work and sprays paint onto the hardware in the roller 11. Since the hardware rolls in the roller 11, the paint can be evenly coated on all surfaces of the hardware.

[0021] As one implementation method in this embodiment, such as Figure 2 and Figure 3As shown, the drive assembly 2 includes a groove 21 formed on the side wall of the processing frame 1. A slider 22 is slidably connected to the groove 21. A rack 23 is fixedly connected to the side wall of the slider 22. A mounting plate 24 is also fixedly connected to the side wall of the processing frame 1. A cylinder 25 is fixedly mounted on the upper end face of the mounting plate 24. The piston end of the cylinder 25 is fixed to the end of the rack 23. A gear 26 is fixedly sleeved on the outer wall of the rotating rod 12 near the rack 23. The rack 23 meshes with the gear 26 for transmission. In actual use, when it is necessary to drive the roller 11 to rotate, the cylinder 25 starts to work, and its piston end moves in a telescoping motion, driving the rack 23. The rack 23 moves linearly along the direction of the slide groove 21. As the rack 23 moves linearly, it meshes with the gear 26. Since the gear 26 is fixedly sleeved on the rotating rod 12, the rotation of the gear 26 will drive the rotating rod 12 to rotate. The rotation of the rotating rod 12 will drive the roller 11 to rotate. The rotation of the roller 11 causes the internal hardware to roll inside the roller 11, thereby ensuring uniform coating of the paint. The rotation angle of the roller 11 is controlled by the length of the rack 23 and the extension length of the piston end of the cylinder 25. Under normal operation, the rotation angle of the roller 11 cannot exceed 85°.

[0022] As one implementation method in this embodiment, such as Figure 1 and Figure 2 As shown, the auxiliary spray assembly 3 includes fixed plates 31 respectively fixedly installed on the upper surface of the support frame 13. A lead screw 32 is rotatably connected between the two fixed plates 31. A drive motor 33 is fixedly installed at one end of the lead screw 32 and is fixed to the support frame 13. A movable sleeve 34 is threaded onto the outer wall of the lead screw 32. A horizontal plate 35 is fixedly connected to the outer wall of the movable sleeve 34. A spray head 36 is fixedly installed on the horizontal plate 35. The feed end of the spray head 36 is connected to an external feeding unit, which provides the corrosion-resistant coating and spray pressure for spraying. The two fixed plates 31 are also connected... A fixed connection is provided with a limiting slide rod 37, and a limiting plate 38 is slidably sleeved on the outer wall of the limiting slide rod 37. One side of the limiting plate 38 is fixed to the side wall of the movable sleeve 34. In actual use, the drive motor 33 drives the lead screw 32 to rotate, thereby causing the movable sleeve 34 on the lead screw 32 to move laterally through the limiting operation of the limiting slide rod 37. This causes the movable sleeve 34 to drive the spray head 36 to move horizontally. The spray head 36 can spray the hardware parts at different positions. The spray head 36 moves back and forth by the forward and reverse rotation of the drive motor 33.

[0023] As one implementation method in this embodiment, such as Figure 1 and Figure 4As shown, the outer wall of the roller 11 is symmetrically provided with mounting ports 4. The roller brush 41 is rotatably connected to the inner side of the mounting port 4. The spray head 36 has a large spray range, so the sprayed corrosion-resistant coating will adhere to the roller brush 41. The rolling of the roller 11 allows the hardware to come into contact with the roller brush 41. In this way, the surface of the hardware will be coated with the corrosion-resistant coating on the roller brush 41, which improves the coating effect to a certain extent.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
