Abstract
Description
Technical Field
[0001] This utility model relates to the field of fume and exhaust gas absorption devices, and in particular to a fume and exhaust gas absorption device for welding equipment. Background Technology
[0002] Welding, as a common metal processing technology, plays a vital role in various fields such as industrial manufacturing, construction, and automobile manufacturing. However, the welding process generates a large amount of fumes and exhaust gases, which contain various harmful substances, such as metal particles and toxic gases, posing a serious threat to the health of operators and environmental safety. Therefore, welding equipment fume and exhaust gas absorption devices have become important equipment for ensuring a safe working environment and reducing the occurrence of occupational diseases.
[0003] Existing welding equipment fume and exhaust gas absorption devices on the market have certain limitations. Many traditional absorption devices have fixed inlet hood positions, making it impossible to flexibly adjust the suction direction according to changes in the welding point. In actual welding operations, the position of the welding point often changes constantly due to factors such as workpiece shape and welding process requirements. A fixed inlet hood cannot always be aligned with the source of fume and exhaust gas, resulting in some fume and exhaust gas not being effectively captured. This reduces the overall fume and exhaust gas capture efficiency of the absorption device, fails to provide a good working environment for operators, and is difficult to meet increasingly stringent environmental standards. Therefore, to address the problem of existing inlet hoods being unable to adjust the suction direction, a welding equipment fume and exhaust gas absorption device that solves the above problems is needed. Utility Model Content
[0004] To address the problem that the intake hood in existing technologies cannot adjust the air intake direction, this application provides a welding equipment fume and exhaust gas absorption device. The starting motor drives the flat gear to rotate, which in turn drives the gear component to rotate. Under the action of the gear component, the air intake pipe rotates, which can make the air intake hood cover a wider area. Pulling the lever releases the lever from the fixed plate, and rotating the lever allows the fixed plate to be pulled out through the handle. Then, the filter plate can be removed from the tenon through the tenon.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A welding equipment fume and exhaust gas absorption device includes an absorption device body.

[0009] As a further improvement of this utility model, a fixing sleeve is fixedly connected to the middle of the front end of the main body of the absorption device, and the fixing sleeve is disposed on the outer wall of the connecting pipe.
[0010] As a further improvement of this utility model, one end of the spring is disposed at the right end of the left limiting plate, and the other end of the spring is disposed at the left end of the right limiting plate.
[0011] As a further improvement of this utility model, a tenon is fixedly connected to the left end of the fixing plate, and the tenon is slidably connected to the right end of the filter plate.
[0012] As a further improvement of this utility model, a rubber ring is fixedly connected to one end of the connector, and the rubber ring is disposed on the inner circumference of the connecting tenon.
[0013] As a further improvement of this utility model, a handle is fixedly connected to the right end of the fixing plate.

[0029] Example 1:
[0030] like Figures 1-4As shown, a welding equipment fume and exhaust gas absorption device includes an absorption device body 1. An exhaust pipe 2 for exhausting gas is fixedly connected to the middle of the top of the absorption device body 1. A fixing plate 16 is connected to the right end of the absorption device body 1 via a slide rod 18 and a clamping rod 21. A filter plate 14 for filtering exhaust gas is connected to the left end of the fixing plate 16 via a slide rail. A connecting pipe 3 is fixedly connected to the front end of the absorption device body 1. An air inlet pipe 8 is connected to the top end of the connecting pipe 3 via a connector 5, a connecting tenon 6, and a connector 7. An air inlet hood 9 for suction is fixedly connected to the front end of the air inlet pipe 8. A motor 13 is mounted on the front side of the top of the absorption device body 1 via a fixing frame. A spur gear 12 is fixedly connected to the drive end of the motor 13. The spur gear 12 is rotatably connected to the top end of the absorption device body 1. A gear component 11 is meshed with the front end of the spur gear 12. The gear component 11 is fixedly connected to the outer wall of the air inlet pipe 8.
[0031] Specifically, during the welding process, the position of the welding point may change continuously. At this time, the starting motor 13 drives the spur gear 12 to rotate, which in turn drives the gear component 11 to rotate. Under the action of the gear component 11, the air intake pipe 8 drives the air intake hood 9 to rotate 180 degrees, which can make the air intake hood 9 cover a wider area and expand the capture range, thereby effectively improving the capture efficiency of smoke and dust exhaust gas.
[0032] The connector 1 5 is located at the top of the connecting pipe 3. The top of the connector 1 5 is fixedly connected to the connecting tenon 6. The outer wall of the connecting tenon 6 is rotatably connected to the connector 2 7. The connector 2 7 is fixedly connected to the bottom of the air intake pipe 8. The middle of the front end of the main body 1 of the absorption device is fixedly connected to the fixing sleeve 4. The fixing sleeve 4 is set on the outer wall of the connecting pipe 3. The top of the connector 1 5 is fixedly connected to the rubber ring 10. The rubber ring 10 is set on the inner circumference of the connecting tenon 6. The right end of the fixing plate 16 is fixedly connected to the handle 17.
[0033] Specifically, under the action of the connecting tenon 6, the connecting part 1 5 and the connecting part 2 7 can rotate, thereby allowing the air intake pipe 8 to rotate on the connecting pipe 3. The rubber ring 10 can prevent gas from leaking from the connection between the connecting part 1 5 and the connecting part 2 7. The fixing sleeve 4 can fix the connecting pipe 3 to the main body 1 of the absorption device. The handle 17 can more easily pull the fixing plate 16 out of the main body 1 of the absorption device.
[0034] Example 2:
[0035] As one of the optimized structural designs for Example 1, such as Figures 1-4As shown, a slide rod 18 is located at the right end of the main body 1 of the absorption device. A locking rod 21 is rotatably connected to the right end of the slide rod 18. The locking rod 21 is set on the inner wall of the fixing plate 16. A spring 20 is set on the outer wall of the slide rod 18. Limiting plates 19 are fixedly connected to the left and right sides of the outer wall of the slide rod 18. One end of the spring 20 is set on the right end of the left limiting plate 19, and the other end of the spring 20 is set on the left end of the right limiting plate 19. A tenon 15 is fixedly connected to the left end of the fixing plate 16. The tenon 15 is slidably connected to the right end of the filter plate 14.
[0036] Specifically, pulling the lever 21 compresses the spring 20, causing the lever 21 to release its engagement with the fixing plate 16. After the lever 21 releases its engagement with the fixing plate 16, rotating the lever 21 allows the filter plate 14 to be removed from the main body 1 of the absorption device via the fixing plate 16. This removes dust and impurities from the surface and internal pores of the filter plate 14, facilitating cleaning and maintenance, restoring the filtration performance of the filter plate 14, and extending its service life. Conversely, after installing the filter plate 14 into the main body 1 of the absorption device via the fixing plate 16, pulling the lever 21 compresses the spring 20 and rotating the lever 21, then releasing the force applied to the lever 21, causes the lever 21 to spring into the slot of the fixing plate 16 under the action of the spring 20, engaging and limiting the fixing plate 16, thereby installing the filter plate 14.
[0037] Working principle: When the main body 1 of the absorption device is started, the fumes and exhaust gases generated during welding are sequentially drawn into the inlet pipe 8 and connecting pipe 3 through the inlet hood 9, and then into the main body 1 of the absorption device through the connecting pipe 3. The fumes and exhaust gases are filtered by the filter plate 14, and then discharged through the outlet pipe 2. When the main body 1 of the absorption device is running, the motor 13 is started, which drives the spur gear 12 to rotate. The spur gear 12 drives the gear component 11 to rotate, and under the action of the gear component 11, the inlet hood 9 rotates 180 degrees through the inlet pipe 8, so that the air intake area of the inlet hood 9 covers a wider area. When the main body 1 of the absorption device is running, the fumes and exhaust gases generated during welding are drawn into the inlet pipe 8 and then discharged through the outlet pipe 2. After the body 1 has been used for a period of time, pull the lever 21 to compress the spring 20, causing the lever 21 to release its engagement with the fixing plate 16. After the lever 21 releases its engagement with the fixing plate 16, rotate the lever 21 to remove the filter plate 14 from the body 1 of the absorption device. Clean the filter plate 14. After cleaning, pull the lever 21 to compress the spring 20 and rotate the lever 21. Then release the force applied to the lever 21. Under the action of the spring 20, the lever 21 will spring into the slot of the fixing plate 16, allowing the filter plate 14 to be installed and restoring its filtering effect.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
