Description

Technical Field

[0001] This utility model relates to the field of automobile production technology, and in particular to a telescopic suction hood for real-time collection of welding fumes in automobiles. Background Technology

[0002] In automobile production, welding equipment is frequently used, such as for car frames. During welding, the high temperature of the electric arc (reaching 3000-6000℃) causes the metal in the welding rod, workpiece, and flux to evaporate and oxidize, forming gaseous metal particles. These particles condense in the air to form tiny particles or aerosols, which are suspended in the working environment and constitute welding fumes. These toxic gases are therefore collected and adsorbed by dust collection equipment in automobile production.

[0003] In existing technologies, to increase the adsorption range, the ends of the pipes are all equipped with air suction masks. However, automobile production lines often operate continuously or for extended periods. Therefore, in actual use, a lot of dust accumulates on the suction mask, requiring regular cleaning to avoid affecting the adsorption capacity. Each cleaning requires stopping the machine, which reduces automobile production efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the actual use of the existing technology, a lot of smoke and dust will adhere to the suction hood, which needs to be cleaned regularly to avoid affecting the suction power. However, each cleaning requires stopping the machine, which reduces the efficiency of automobile production. The proposed invention is a telescopic suction hood for real-time collection of automobile welding fumes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a telescopic suction hood for real-time collection of automotive welding fumes, comprising an expanding mask, a first connecting frame fixedly connected to one end of the inside of the expanding mask, a connecting shaft fixedly connected to one side of the first connecting frame, an assembly rotatably connected to the outside of the connecting shaft, blades fixedly connected to the outer surface of the assembly, a connecting rod fixedly connected to one side of the outer surface of the assembly, a cleaning brush fixedly connected to the side of the connecting rod near the expanding mask, the cleaning brush fitting against the inner wall of the expanding mask, and a limiting arc rod fixedly connected between one end of two adjacent connecting rods.

[0006] Preferably, a telescopic tube is provided on one side of the expanding mask, and a central cleaning cylinder is provided between two adjacent telescopic tubes.

[0007] Preferably, assembly grooves are provided on both sides of the outer surface of the intermediate cleaning cylinder and on one side of the outer surface of the expansion mask, and the assembly grooves are inserted into the end of the telescopic tube.

[0008] Preferably, a second connecting frame is fixedly connected to both sides of the middle part inside the intermediate cleaning cylinder, and a rotating shaft is rotatably connected inside the second connecting frame.

[0009] Preferably, rotating fan blades are fixedly connected to both ends of the rotating shaft.

[0010] Preferably, a vibrating plate is fixedly connected inside the intermediate cleaning cylinder and between the two No. 2 connecting frames.

[0011] Preferably, a striking rod is fixedly connected to the outer surface of the rotating shaft.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the blades are designed to rotate by the airflow during dust adsorption, thus enabling the cleaning brush to clean the inner wall of the mask. Simultaneously, the dust particles that fall off the brush are carried along with the airflow, extending the cleaning interval and reducing downtime, thereby improving production efficiency. Furthermore, the limiting arc rod restricts the end of the connecting rod, ensuring the cleaning brush contacts the inner wall of the mask to prevent deformation and bending due to centrifugal force, thus guaranteeing stability. This design eliminates the need for a separate drive component; only the power of the extraction equipment needs to be increased. It features a simple structure, low maintenance costs, and ease of use.

[0013] 2. In this utility model, the rotating shaft and rotating fan blades are arranged in a double-sided installation, resulting in a larger contact area with the airflow. This further increases the force when the striking rod rotates, making the rotation of the striking rod smoother and improving its stability. At the same time, in conjunction with the vibrating plate, the striking rod strikes the vibrating plate when the rotating shaft rotates. The resulting vibration can dislodge some of the dust adhering inside the telescopic tube, facilitating subsequent disassembly and cleaning of the telescopic tube. In addition, this design divides the telescopic tube into sections, making it easier to insert cleaning components into the telescopic tube during cleaning, making subsequent cleaning more convenient and faster, and reducing the difficulty of cleaning.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a telescopic suction hood for real-time collection of automotive welding fumes, including a wide-face mask 1. One end of the wide-face mask 1 is fixedly connected to a first connecting frame 10. One side of the first connecting frame 10 is fixedly connected to a connecting shaft 11. The outer side of the connecting shaft 11 is rotatably connected to a mounting bracket 7. The outer surface of the mounting bracket 7 is fixedly connected to a blade 8. One side of the outer surface of the mounting bracket 7 is fixedly connected to a connecting rod 4. The side of the connecting rod 4 near the wide-face mask 1 is fixedly connected to a cleaning brush 5. The cleaning brush 5 is in contact with the inner wall of the wide-face mask 1. A limiting arc rod 6 is fixedly connected between one end of two adjacent connecting rods 4.

[0019] The specific settings and functions of this embodiment are described in detail below. By using the blades 8, the airflow during dust adsorption drives the blades 8 to rotate, thereby cleaning the inner wall of the expanding mask 1 with the cleaning brush 5. At the same time, the dust that falls off the cleaning brush can also flow with the airflow. In this way, the cleaning interval can be extended, thereby reducing the number of downtimes and improving the production efficiency of the vehicle. At the same time, by setting the limiting arc rod 6, the end of the connecting rod 4 can be restricted to ensure that the cleaning brush 5 can contact the inner wall of the expanding mask 1, so as to avoid deformation and bending due to centrifugal force and ensure the stability of use. This design does not require a separate drive component; it only requires increasing the power of the air extraction equipment. The structure is simple, the maintenance cost is low, and it is easy to use.

[0020] Example 2: Figure 1 - Figure 5 As shown, a telescopic tube 2 is provided on one side of the expansion mask 1, and a middle cleaning cylinder 3 is provided between two adjacent telescopic tubes 2. Assembly slots 12 are provided on both sides of the outer surface of the middle cleaning cylinder 3 and on one side of the outer surface of the expansion mask 1. The assembly slots 12 are inserted into the ends of the telescopic tubes 2. Two connecting frames 15 are fixedly connected to the middle part of the middle cleaning cylinder 3 on both sides. A rotating shaft 9 is rotatably connected inside the two connecting frames 15. Rotating fan blades 13 are fixedly connected to both ends of the rotating shaft 9. A vibrating plate 16 is fixedly connected inside the middle cleaning cylinder 3 and between the two connecting frames 15. A striking rod 14 is fixedly connected to the outer surface of the rotating shaft 9. The connection between the expansion mask 1, the telescopic tube 2, and the middle cleaning cylinder 3 is fixedly installed by using a hose clamp.

[0021] The overall effect of this embodiment is that, by setting the rotating shaft 9 and the rotating fan blade 13 with double-sided installation, the contact surface with the airflow is larger, which can further increase the force when the striking rod 14 rotates, making the rotation of the striking rod 14 smoother and improving the stability of use. At the same time, in conjunction with the vibration plate 16, when the rotating shaft 9 rotates, the striking rod 14 strikes the vibration plate 16, and the resulting vibration can shake off some of the dust attached to the telescopic tube 2, so as to facilitate the subsequent disassembly and cleaning of the telescopic tube 2. At the same time, this design divides the telescopic tube 2 into sections, making it easier to insert the cleaning parts into the telescopic tube 2 during cleaning, making subsequent cleaning more convenient and quick, and reducing the difficulty of cleaning.

[0022] The usage and working principle of this device are as follows: When in use, connect the telescopic tube 2 at the end to the adsorption collection device, and adjust the bending and extension length of the telescopic tube 2 so that the flared end of the expanding mask 1 is above the welding area. Turn on the adsorption collection device, and airflow enters from the expanding mask 1. The airflow causes the assembly 7 and rotating fan blade 13 to rotate. The cleaning brush 5 brushes away the dust on the inner wall of the expanding mask 1. The dust enters the telescopic tube 2 with the airflow. The rotating fan blade 13 drives the rotating shaft 9 to rotate, causing the striking rod 14 to strike the vibrating plate 16, causing the vibrating plate 16 to vibrate. Through the transmission of force, the part of the telescopic tube 2 near the middle cleaning cylinder 3 vibrates, reducing the amount of dust adhering. Subsequently, the dust enters the adsorption collection device, is filtered, and collected inside the adsorption collection device.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
