During operation, when butt welding the aluminum profile window frame, by placing two sections of aluminum profiles on the fixing component, controlling the power supply of the electric slider 18, moving the two sections of aluminum profiles towards the direction close to the annular pipe 14, and feeding the aluminum profiles into the first protective cover 11 through the feeding port 16. At this time, the ends of the two sections of aluminum profiles are butted together and placed inside the annular pipe 14 and aligned with the welding nozzles 15. At this time, the second protective cover 19 is pushed by the electric slider 18 and fits with the side wall of the first protective cover 11 to form a closed working environment. Then, turn on the switch of the welding machine 12 to make the welding nozzles 15 weld the aluminum profiles, and turn on the switch of the air extractor 111 to make the air extractor 111 extract air from the inside of the first protective cover 11 through the air extraction port 114, thereby sucking away the smoke and dust generated during the welding process of the aluminum profiles, reducing the problem of smoke and dust drifting into the air and polluting the working environment. Through the cooperation of the air extractor 111 and the second protective cover 19, the smoke and dust generated during the welding process of the aluminum profiles can be purified, thereby improving the safety during the butt welding process of the aluminum profile window frame.

[0023] AsFigure 1 and Figure 5 As shown in Figure 5 , a plurality of telescopic cylinders 2 are fixedly connected to the side walls of the first protective cover 11 and the side walls of the second protective cover 19; the telescopic cylinders 2 are arranged in a circular array around the feeding port 16; the output ends of the telescopic cylinders 2 are fixedly connected with positioning plates 21; an elastic bandage 22 is fixedly connected between a pair of adjacent positioning plates 21; an elastic cloth 23 is fixedly connected to the inner side wall of the feeding port 16; the elastic cloth 23 and the side wall of the positioning plate 21 are fixedly connected to each other; the elastic cloth 23 and the side wall of the elastic bandage 22 are fixedly connected to each other. During operation, the aluminum profiles to be butt-welded are conveyed to the butt-welding position by the electric slider 18, and then the switch of the telescopic cylinder 2 is controlled to make the telescopic cylinder 2 drive the positioning plate 21 to move towards the aluminum profile, and the aluminum profile is clamped and fixed by the positioning plate 21. At this time, the elastic cloth 23 located between the positioning plate 21 and the feeding port 16 further seals the feeding port 16, increases the sealing performance between the first protective cover 11 and the second protective cover 19, reduces the possibility of welding fumes escaping to the outside through the feeding port 16, and improves the cleaning effect of the fumes generated during the welding process.

[0024] As Figure 6 shown in Figure 6 , the fixing assembly includes a fixing frame 3; the fixing frame 3 is fixedly connected to the top of the electric slider 18; a pair of adjusting screws 31 are symmetrically threadedly connected to the side wall of the fixing frame 3; the ends of the adjusting screws 31 close to each other are rotatably connected with clamping plates 32; the bottom of the clamping plate 32 and the top of the fixing frame 3 are in contact with each other. During operation, by providing a fixing frame 3 on the electric slider 18, the aluminum profile is placed on the fixing frame 3, and then the operator rotates the adjusting screws 31 at both ends respectively to make the adjusting screws 31 drive the clamping plates 32 to move towards the aluminum profile until the clamping plates 32 clamp the aluminum profile in the middle. The aluminum profile is clamped and fixed through the cooperation of the clamping plates 32 and the adjusting screws 31, and aluminum profiles of different sizes and models can be fixed and positioned, improving the applicability of the device.

[0025] As Figure 3 and Figure 6As shown, the connection component includes a first connecting rod 4; there are a pair of the first connecting rods 4; the pair of the first connecting rods 4 are symmetrically fixed on the side wall of the electric slider 18; the end of the first connecting rod 4 is slidably connected to a second connecting rod 41; the second connecting rod 41 is fixedly connected to the side wall of the second protective cover 19; a return spring 42 is fixedly connected to the end of the second connecting rod 41 located inside the first connecting rod 4; the other end of the return spring 42 is fixedly connected to the inner side wall of the first connecting rod 4. During operation, a first connecting rod 4 and a second connecting rod 41 are provided between the electric slider 18 and the second protective cover 19. The electric slider 18 pushes the second protective cover 19 towards the position where the first protective cover 11 is located through the first connecting rod 4 and the second connecting rod 41. When the second protective cover 19 and the first protective cover 11 come into contact with each other, the electric slider 18 will drive the aluminum profile to continue moving. At this time, the second connecting rod 41 will extend into the first connecting rod 4 under the continuous movement of the electric slider 18, and under the elastic action of the return spring 42, the second protective cover 19 and the first protective cover 11 will be closely attached, making the sealing between the first protective cover 11 and the second protective cover 19 more stable.

[0026] As Figures 1 to 5 shown, an air inlet 5 is formed on the side wall of the first protective cover 11; a nitrogen generator 51 is fixedly connected to the top of the welding table 1; the output end of the nitrogen generator 51 is fixedly connected to a connecting pipe 52; the end of the connecting pipe 52 is fixedly connected to the side wall of the first protective cover 11; the connecting pipe 52 is sleeved on the air inlet 5. During operation, when the welding nozzle 15 is welding, oxygen is usually added to the welding area for flame retardant. However, adding oxygen for a long time will cause a high oxygen content in the internal space, which will cause the aluminum profile to oxidize quickly. At this time, by turning on the switch of the nitrogen generator 51, the nitrogen generator 51 uses the connecting pipe 52 to deliver nitrogen into the first protective cover 11 to balance the oxygen content during welding and reduce the problem of aluminum profile oxidation caused by too high oxygen content, improving the stability of the butt welding of the aluminum profile.

[0027] As Figure 5 shown, a roller 6 is rotatably connected to the side wall of the positioning plate 21; there are multiple rollers 6 arranged in an array. During operation, during the butt welding process, one end of the aluminum profile needs to move forward continuously. At this time, by providing rollers 6 on the positioning plate 21, the wear on the surface of the aluminum profile can be reduced during the movement of the aluminum profile, improving the protection effect on the aluminum profile.

[0028] As Figures 2 to 4As shown, a first sealing ring 7 is fixedly connected to one side of the first protective cover 11 close to the second protective cover 19; a second sealing ring 71 is fixedly connected to one side of the second protective cover 19 close to the first protective cover 11. During operation, by staggeredly arranging the first sealing ring 7 and the second sealing ring 71, when the second protective cover 19 approaches the first protective cover 11 and fits with the first protective cover 11, the first sealing ring 7 and the second sealing ring 71 seal the connection between the first protective cover 11 and the second protective cover 19, improving the sealing performance of the first protective cover 11 and the second protective cover 19.

[0029] As Figure 3 and Figure 7 shown, a blanking groove 8 is formed in the middle of the welding table 1; the blanking groove 8 is located below the annular pipe 14; a pair of fixing plates 81 are fixedly connected to the bottom of the welding table 1; the pair of fixing plates 81 are symmetrically arranged on both sides of the blanking groove 8; a plug rod 82 is slidably connected to the middle of the fixing plate 81; a waste residue collection box 83 is engaged inside the blanking groove 8. During operation, welding slag will be generated during the butt welding of aluminum profiles and will fall off. These welding slags directly fall onto the tabletop and are difficult to clean after cooling. At this time, by arranging the waste residue collection box 83 below the annular pipe 14, the welding slag falls into the waste residue collection box 83. After collecting for a period of time, by pulling the plug rod 82, the plug rod 82 is detached from the fixing plate 81, and the waste residue collection box 83 is taken out from below and replaced. Then, the plug rod 82 is inserted into the fixing plate 81 to support the waste residue collection box 83, improving the collection effect of the welding slag.

[0030] As Figure 6 shown, a measuring ruler 9 is slidably connected to the side wall of the fixing frame 3; a pull ring 91 is fixedly connected to the end of the measuring ruler 9; scales are provided on the side wall of the measuring ruler 9. During operation, by providing the measuring ruler 9 on the fixing frame 3, when the aluminum profile is placed on the fixing frame 3, by sliding the measuring ruler 9, the measuring ruler 9 is fitted to the end of the aluminum profile, and by observing the scales on the measuring ruler 9, the protruding length of the aluminum profile on the fixing frame 3 can be quickly determined, making the butt welding and fixing of the aluminum profile more convenient.

[0031] As Figure 1 shown, a light filtering and isolation window 101 is installed on the side wall of the first protective cover 11. During operation, through the light filtering and isolation window 101, the operator can conveniently observe the butt welding situation of the aluminum profile and reduce the influence of strong light during welding on the operator's eyes, improving the safety during welding.

[0032] During operation, when butt-welding aluminum alloy window frames, place two sections of aluminum alloy profiles on the fixing components. By controlling the power supply of the electric slider 18, move the two sections of aluminum alloy profiles towards the direction close to the annular pipe 14. Feed the aluminum alloy profiles into the interior of the first protective cover 11 through the feeding port 16. At this time, the ends of the two sections of aluminum alloy profiles are butted together and placed inside the annular pipe 14 and aligned with the welding nozzle 15. At this time, the second protective cover 19 is pushed by the electric slider 18 to fit against the side wall of the first protective cover 11, forming a closed working environment. Then, turn on the switch of the welding machine 12 to make the welding nozzle 15 weld the aluminum alloy profiles, and turn on the switch of the air extractor 111 to make the air extractor 111 extract air from the interior of the first protective cover 11 through the air extraction port 114, thereby sucking away the fumes generated during the welding of the aluminum alloy profiles, reducing the problem of fumes spreading into the air and polluting the working environment. Through the cooperation of the air extractor 111 and the second protective cover 19, the fumes generated during the welding of the aluminum alloy profiles can be purified, thereby improving the safety during the butt-welding of the aluminum alloy window frames.

[0033] Use the electric slider 18 to convey the aluminum alloy profiles to be butt-welded to the butt-welding position. Then, control the switch of the telescopic cylinder 2 to make the telescopic cylinder 2 drive the positioning plate 21 to move towards the direction close to the aluminum alloy profiles, and clamp and fix the aluminum alloy profiles through the positioning plate 21. At this time, the elastic cloth 23 located between the positioning plate 21 and the feeding port 16 further seals the feeding port 16, increasing the sealing performance between the first protective cover 11 and the second protective cover 19, reducing the possibility of welding fumes escaping to the outside through the feeding port 16, and improving the cleaning effect of the fumes generated during welding.

[0034] By providing a fixing frame 3 on the electric slider 18, place the aluminum alloy profiles on the fixing frame 3. Then, make the operator rotate the adjusting screws 31 at both ends respectively, so that the adjusting screws 31 drive the clamping plates 32 to move towards the direction close to the aluminum alloy profiles until the clamping plates 32 clamp the aluminum alloy profiles in the middle. Clamp and fix the aluminum alloy profiles through the cooperation of the clamping plates 32 and the adjusting screws 31, which can fix and position aluminum alloy profiles of different sizes and models, improving the applicability of this device.

[0035] By providing a first connecting rod 4 and a second connecting rod 41 between the electric slider 18 and the second protective cover 19, the electric slider 18 pushes the second protective cover 19 towards the position of the first protective cover 11 through the first connecting rod 4 and the second connecting rod 41. When the second protective cover 19 contacts the first protective cover 11, the electric slider 18 will drive the aluminum alloy profiles to continue moving. At this time, the second connecting rod 41 will extend into the first connecting rod 4 under the continuous movement of the electric slider 18, and under the elastic action of the return spring 42, tightly fit the second protective cover 19 and the first protective cover 11, making the sealing between the first protective cover 11 and the second protective cover 19 more stable.

[0036] When the welding nozzle 15 is welding, oxygen is usually added to the welding area for flame retardancy. However, long-term addition of oxygen will cause a relatively high oxygen content in the internal space, which will cause the aluminum profile to oxidize rapidly. At this time, by turning on the switch of the nitrogen generator 51, the nitrogen generator 51 uses the connecting pipe 52 to transport nitrogen into the first protective cover 11, balancing the oxygen content during welding, reducing the problem of aluminum profile oxidation caused by excessive oxygen content, and improving the stability of the aluminum profile during butt welding.

[0037] During the butt welding process, it is necessary to continuously move one end of the aluminum profile forward. At this time, by providing rollers 6 on the positioning plate 21, the wear on the surface of the aluminum profile can be reduced during the movement of the aluminum profile, improving the protection effect on the aluminum profile.

[0038] By alternately arranging the first sealing ring 7 and the second sealing ring 71, when the second protective cover 19 approaches the first protective cover 11 and fits with the first protective cover 11, the first sealing ring 7 and the second sealing ring 71 seal the connection between the first protective cover 11 and the second protective cover 19, improving the sealing performance of the first protective cover 11 and the second protective cover 19.

[0039] When the aluminum profile is butt-welded, welding slag will fall off. These welding slags directly fall onto the tabletop and are difficult to clean after cooling. At this time, by arranging a waste slag collection box 83 below the annular pipe 14, the welding slag falls into the waste slag collection box 83. After collecting for a period of time, by pulling the insertion rod 82, the insertion rod 82 is detached from the fixing plate 81, and the waste slag collection box 83 is taken out from below and replaced. Then the insertion rod 82 is inserted into the fixing plate 81 to support the waste slag collection box 83, improving the collection effect of the welding slag.

[0040] By providing a measuring scale 9 on the fixing frame 3, when the aluminum profile is placed on the fixing frame 3, by sliding the measuring scale 9, the measuring scale 9 is fitted to the end of the aluminum profile, and observing the scale on the measuring scale 9, the protruding length of the aluminum profile on the fixing frame 3 can be quickly determined, making the butt-welding fixation of the aluminum profile more convenient.

[0041] Through the light-filtering isolation window 101, the operator can conveniently observe the butt-welding situation of the aluminum profile and reduce the influence of strong light during welding on the operator's eyes, improving the safety during welding.
