Description

Technical Field

[0001] This utility model relates to the field of spray coating protection technology, and in particular to a paint mist prevention device for a coating conveyor chain. Background Technology

[0002] In the painting production process, the conveyor chain, as a key material transport component, plays a crucial role in production efficiency and product quality. However, the large amount of paint mist generated during the painting process has become a thorny problem threatening the normal operation of the conveyor chain.

[0003] Currently, existing painting conveyor chains lack protective devices and are directly exposed to the working environment. When in a painting environment, tiny droplets and particles in the paint mist are dispersed by the airflow generated during spraying. Once this paint mist comes into contact with the chain, it easily adheres to it, causing obstruction between chain links and frequent jamming. Therefore, in order to better protect the chain, promote technological progress in the industry, and improve core technological competitiveness, this application proposes a new implementation scheme for painting conveyor chains that differs from existing technologies. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the lack of existing protective devices, and to propose a paint mist prevention device for coating conveyor chains.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A paint mist prevention device for a coating conveyor chain includes an I-shaped block and a chain. Protective plates are fixedly connected to both sides of the I-shaped block. Two observation windows are embedded in one side of the protective plate. A rubber block is fixedly connected to the inner side of the protective plate. An air inlet pipe is fixedly connected to the bottom end of the protective plate. An air outlet is threadedly connected to one side of the air inlet pipe.

[0006] Furthermore, the bottom of the I-shaped block is provided with multiple connecting frames, and rollers are fixedly connected to both ends of the connecting frames, and the rollers roll on the I-shaped block.

[0007] Furthermore, a mounting bracket is fixedly connected to the bottom of the connecting frame, and a hook is fixedly connected to the bottom end between the two mounting brackets.

[0008] Furthermore, the top of the mounting bracket passes through a chain, and the chain is fixed to the mounting bracket by bolts.

[0009] Furthermore, the connecting frame has a C-shaped structure.

[0010] The beneficial effects of this utility model are as follows: 1. Gas is pumped into the air inlet pipe and then sprayed out from the air outlet, forming two downward-crossing air curtains to block the paint mist from rising. Rubber blocks further block the paint mist, preventing it from rising. At the same time, two protective plates are fixed to both sides of the I-shaped block to form a protective cavity, preventing paint mist from adhering to the chain, thus achieving multiple anti-paint mist effects.

[0011] 2. The movement of the hook is guided by the rollers rolling on the I-shaped block, thereby improving the stability of the workpiece movement. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-3 A paint mist prevention device for a coating conveyor chain includes an I-shaped block 1 and a chain 5. Protective plates 7 are fixed to both sides of the I-shaped block 1 by bolts. The protective plates 7 are made of lightweight and wear-resistant PP plastic material, which is resistant to paint solvent corrosion, prevents them from being dissolved by paint mist, and can block the paint mist drifting from both sides from directly contacting the chain 5. Two observation windows 8 are embedded on one side of the protective plate 7. A rubber block 9 is glued to the inside of the protective plate 7. The rubber block 9 fits tightly with the edge of the mounting frame 4. The elasticity of the rubber block 9 can fill the assembly gap, thus completing the construction of the passive physical isolation structure. The bottom end of the protective plate 7 is fixed with an air inlet pipe 10 by bolts. An air outlet 11 is threadedly connected to one side of the air inlet pipe 10. Gas is input into the air inlet pipe 10 by an air pump and then sprayed out from the air outlet 11, thereby forming two downward-crossing air curtains, which in turn block the rise of paint mist.

[0016] The bottom of the I-shaped block 1 is provided with multiple connecting frames 3. Both ends of the connecting frames 3 are fixed with rollers 2 by bolts. The rollers 2 roll on the I-shaped block 1. The rollers 2 are engaged in the slide rail of the I-shaped block 1 and can roll smoothly. The rolling of the rollers 2 on the I-shaped block 1 maintains the stability of the movement and prevents the chain 5 from driving the device to shake, causing the protective plate 7 to shift. This ensures that the protective cavity is always aligned with the running trajectory of the chain 5.

[0017] The bottom of the connecting frame 3 is welded with a mounting frame 4. The bottom end between the two mounting frames 4 is fixed with a hook 6 by bolts. The hook 6 is used to hang the workpiece to be painted. The position of the hook 6 is lower than the protective plate 7 to ensure that the workpiece is sprayed below the painting area.

[0018] The top of the mounting bracket 4 passes through the chain 5, and the chain 5 is fixed to the mounting bracket 4 by bolts. The top of the mounting bracket 4 passes through the gap between the chain links of the chain 5 and is fixed to the chain links by bolts to ensure that the mounting bracket 4 and the chain 5 move synchronously.

[0019] The connecting frame 3 has a C-shaped structure.

[0020] The working principle of this embodiment is as follows: When in use, firstly, the workpiece to be coated is hung on the hook 6. Then, the coating production line is started and moves along the preset track via the chain 5, thereby driving the mounting frame 4, the hook 6, and the workpiece to be coated to move synchronously. At the same time, the roller 2 rolls on the I-shaped block 1, thereby improving the stability of the workpiece movement. During the movement, the workpiece is sprayed. During the spraying process, the air inlet pipe 10 is connected to an external air pump. The air pump inputs gas into the air inlet pipe 10 and then sprays it out from the air outlet 11, thereby forming two downward-crossing air curtains, which block the paint mist from rising. The rubber block 9 further blocks the paint mist, preventing it from rising. At the same time, by fixing two protective plates 7 to both sides of the I-shaped block 1 to form a protective cavity, the paint mist is prevented from adhering to the chain 5, so as not to affect the rotation of the chain 5.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
