[0022] The present application will be further explained below with reference to specific implementation methods.

[0023] Example 1 like Figure 1-3 As shown, the slag blowing mechanism for welding electrode plates provided in this embodiment includes a main body 1, a first mounting plate 2, a second mounting plate 3, a first mounting base 4, a second mounting base 5, a first blowing pipe 6, a second blowing pipe 7, and an air pump 8; The air pump 8 is connected to the first blowpipe 6 and the second blowpipe 7 via the air blowing passage 9. The first blowpipe 6 and the second blowpipe 7 are respectively fixedly mounted on the first mounting base 4 and the second mounting base 5; The first mounting base 4 and the second mounting base 5 are respectively disposed on the first mounting plate 2 and the second mounting plate 3; The first mounting plate 2 and the second mounting plate 3 are fixedly disposed on both sides of the welding area 10 of the main body 1.

[0024] In this embodiment, the mounting base and the mounting plate can have several connection relationships. The first is fixed welding, where the mounting base is welded to the mounting plate and does not move. Alternatively, the mounting base and the mounting plate can be connected using fasteners.

[0025] As a further embodiment of this embodiment, the first blowpipe 6 and the second blowpipe 7 are provided with two or more air outlets 11 along the axial direction, and the air outlets 11 point to the welding area 10.

[0026] like Figure 4 As shown, as a further embodiment of this example, the air outlets 11 provided on the first blowpipe 6 and the second blowpipe 7 are staggered in a horizontal position along the axial direction.

[0027] By staggering the air outlets 11, the welding slag in the welding area 10 can be completely blown away, preventing the two airflows from meeting and canceling each other out.

[0028] As a further embodiment of this embodiment, the first mounting plate 2 and the first mounting base 4 are fixedly connected by fasteners; The second mounting plate 3 and the second mounting base 5 are fixedly connected by fasteners.

[0029] As a further embodiment of this invention, the first blowpipe 6 and the second blowpipe 7 are respectively fixedly mounted on the first mounting base 4 and the second mounting base 5 by locking rings 12.

[0030] As a further embodiment of this example, the first blowpipe 6 and the second blowpipe 7 are hollow tubes, one end of which is connected to the air pump 8, and the other end is fixedly provided with a plug to block the first blowpipe 6 and the second blowpipe 7, so that the airflow provided by the air pump 8 is blown out from the air outlet 11.

[0031] As a further embodiment of this invention, a gas filter structure 13 is also provided in the air path through which the air pump 8 connects to the first air pipe and the second air pipe.

[0032] Since particulate matter may be present in the air of the welding workshop, the gas supplied by the air pump 8 needs to be filtered. The gas filter structure 13 is prior art, and any existing gas filter structure 13 can be used; this application does not impose further limitations.

[0033] As a further embodiment of this invention, a solenoid valve 14 is also provided in the air circuit where the air pump 8 is connected to the first air pipe and the second air pipe.

[0034] The function of the solenoid valve 14 is to control the opening and closing of the gas path in this application. When slag blowing is required, the solenoid valve 14 is opened to make the gas path unobstructed, and the solenoid valve 14 is closed to stop slag blowing after the slag blowing is finished.

[0035] For the slag removal mechanism, it is necessary to clean the electrode slag without affecting the welding motion trajectory of the welding machine. The slag removal function of the electrode is achieved by blowing air on the electrode side. The gas blowing does not affect the welding motion trajectory and can also achieve the slag removal function of the electrode.

[0036] By adopting the above technical solution, this application has the following beneficial effects: (1) The first blowpipe 6 and the second blowpipe 7 are provided with multiple air outlets 11 pointing to the welding area 10 along the axial direction, and the air outlets 11 are staggered in the axial horizontal position, which can more thoroughly blow away the welding slag in the welding area 10, avoid the airflow canceling each other, and effectively improve the slag blowing quality.

[0037] (2) The mounting base and the mounting plate can be connected by fixed welding or fasteners. The first blowpipe 6 and the second blowpipe 7 are fixed on the mounting base by locking ring 12, providing a variety of installation options, which facilitates installation and adjustment according to actual needs and enhances the applicability of the mechanism.

[0038] (3) The first blowpipe 6 and the second blowpipe 7 are hollow tubes. One end is connected to the air pump 8, and the other end is sealed with a plug to ensure that the airflow provided by the air pump 8 can be stably blown out from the air outlet 11, so as to achieve effective control of the slag blowing airflow.

[0039] (4) A gas filter structure 13 is installed on the gas supply line of the air pump 8, which can filter out particulate matter in the air, ensure the purity of the slag blowing gas flow, reduce the contamination of the welding area 10 and the electrode, and help improve the welding quality.

[0040] (5) A solenoid valve 14 is installed on the gas line, which can flexibly control the opening and closing of the gas line. It can be opened when slag blowing is required and closed after the end. The operation is simple and convenient, and does not affect the welding action trajectory of the welding machine. The electrode slag removal function is realized without affecting the welding process.

[0041] Example 2 like Figure 5-8 As shown, the slag blowing mechanism for welding electrode plates provided in this embodiment differs from that in Embodiment 1 in that: the first mounting plate 2 and the second mounting plate 3 are respectively provided with a first slide rail 15 and a second slide rail 16; The lower ends of the first mounting base 4 and the second mounting base 5 are respectively fixedly provided with a first slider 17 and a second slider 18 that are adapted to the first slide rail 15 and the second slide rail 16; The first blowpipe 6 and the second blowpipe 7 move closer to or further away from the welding area 10 through the guiding and limiting action of the first slide rail 15 and the first slider 17, and the second slide rail 16 and the second slider 18.

[0042] As a further implementation of this embodiment, it also includes a first control air path 19 and a second control air path 20; One end of the first control air passage 19 is connected to the air pump 8, and the other end extends into the first slide rail 15 and is connected to the first slider 17 through the first telescopic tube 21. One end of the second control air passage 20 is connected to the air pump 8, and the other end extends into the second slide rail 16 and is connected to the second slider 18 through the second telescopic tube 22.

[0043] As a further embodiment of this embodiment, a first spring 23 is also provided inside the first slide rail 15; A second spring 24 is also provided inside the second slide rail 16; One end of the first spring 23 is fixedly connected to the side wall of the first slide rail 15, and the other end abuts against the side of the first slider 17 away from the first telescopic tube 21. One end of the second spring 24 is fixedly connected to the side wall of the second slide rail 16, and the other end abuts against the side of the second slider 18 away from the second telescopic tube 22.

[0044] In this embodiment, the mounting base and the mounting plate are not fixed together; the slider rail can be used for auxiliary guidance and limiting.

[0045] In this embodiment, the slag blowing mechanism for welding electrode plates operates by having the air pump 8 supply air that passes through the gas filter structure 13 and the solenoid valve 14, then splitting into two paths on each side. One path enters the blowing pipe through the blowing air path 9 and blows out, achieving the slag blowing function. The other path, through the control air path, pushes the slider towards the spring, thereby driving the blowing pipe to move. This allows the blowing pipe to move horizontally during air blowing, thus blowing the welding slag to both sides. When slag removal stops, the solenoid valve 14 closes. At this time, the spring drives the slider to return to its original position and retracts the telescopic rod. The gas in the retracting pipe and the control air path then enters the blowing air path 9 and is blown out through the air outlet 11, thus achieving automatic return of the device to its original position.

[0046] By adopting the above technical solution, this application has the following beneficial effects: (1) Using the first control air path 19 and the second control air path 20, combined with the airflow provided by the air pump 8, the slider is connected to the telescopic tube to drive the slider, thereby driving the blowpipe to move. This driving method has a simple structure and is easy to control. It can realize the translation of the blowpipe when blowing air, which helps to blow the welding slag to both sides and improve the slag blowing effect.

[0047] (2) A first spring 23 and a second spring 24 are set. After the blowing stops, the spring can drive the slider to return to its original position, so that the telescopic rod can retract. At the same time, the gas in the gas path is controlled to enter the blowing gas path 9 and blow out from the gas outlet 11, realizing the automatic return of the device without manual intervention, which improves the convenience and efficiency of operation.

[0048] (3) The airflow provided by the air pump 8 is used for both slag blowing and driving the movement of the blowpipe, realizing the integration of functions, reducing the complexity and cost of the equipment, while ensuring the coordinated work of slag blowing and blowpipe position adjustment, and improving the overall work efficiency.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
