[0041] Furthermore, referring to Figure 5 , 6The inner center of the middle frame 6 is rotatably connected with a limiting rod 8, a bevel gear 10 is fixed to the inner end of the limiting rod 8, and another bevel gear meshing with the bevel gear 10 on the limiting rod 8 is fixed to the peripheral side of the rotating rod 9, and a knob 303 located on the outer side of the middle frame 6 is fixed to the outer end of the limiting rod 8. Therefore, when the limiting rod 8 is rotated by the knob 303, the limiting rod 8 can rotate the gears at both ends of the rotating rod 9 through the two meshing bevel gears 10, and then link the longitudinal seat 503 through the vertical rack 506, so that the upper and lower horizontal frames 501 between the left and right longitudinal seats 503 are close to or away from each other. Limiting grooves are provided on the upper and lower sides of the limiting rod 8, and the limiting rod 8 passes through the center seat 301 and the spur gear 305. The center seat 301 and the center of the spur gear 305 are both provided with through grooves corresponding to the limiting grooves. Therefore, when the limiting rod 8 rotates, the spur gear 305 sleeved on its peripheral side also rotates accordingly, and then the vertical frames 502 on both sides are linked to each other through the meshing horizontal racks 507. , a slider is provided at the intersection of the horizontal frame 501 and the vertical frame 502, and the slider slides up and down in the vertical frame 502, and the slider slides left and right in the horizontal frame 501, and a suction cup 2 505 is installed on the inner side of the slider. Due to the setting of the slider, when the limiting rod 8 is rotated in a clockwise direction, the upper and lower horizontal frames 501 and the left and right vertical frames 502 are close to the center, thereby realizing the gathering of the four corner suction cups 2 505. When the limiting rod 8 is rotated in another clockwise direction, the four corner suction cups 2 505 are dispersed in four directions. Therefore, the position of the four corner suction cups 2 505 can be adjusted by rotating the limiting rod 8 to adapt to the adsorption of aluminum curtain walls of different sizes. A section of thread is opened at the inner end of the knob 303, and a corresponding fixing knob 1 304 is sleeved on the outer side of the thread of the knob 303. After determining the adjustment position of the suction cup 2 505, the fixing knob 1 304 at the thread of the knob 303 is rotated so that the fixing knob 1 304 is close to the outer side of the middle frame 6, and the fixing limiting rod 8 no longer rotates;

[0042] Furthermore, a manual air cavity tube 504 connected to the second suction cup 505 is installed on the outside of the slider, and a piston that slides inside and outside is arranged in the manual air cavity tube 504. A pull button 508 is rotatably connected to the outside of the piston, and a limiting protrusion corresponding to the pull button 508 is arranged on the outer end of the manual air cavity tube 504. The aluminum plate curtain wall to be welded is placed on the four-corner suction cups 505 of the horizontal movable frame 2, and the piston in the manual air cavity tube 504 is pulled by the pull button 508, so that negative pressure is generated in the second suction cup 505, sucking the front aluminum plate curtain wall, and the pull button 508 is rotated to fall outside the limiting protrusion, so as to limit the pull button 508 and the connected piston, maintain continuous negative pressure inside the second suction cup 505, and achieve stable adsorption of the aluminum plate curtain wall;

[0043] Furthermore, referring to Figure 3 , 67. A stud 13 penetrating the center of the limit block 7 is fixed on the inner side of the bottom slide 201. A fixing knob 14 close to the surface of the limit block 7 is threadedly connected to the stud 13. The movable frame 2 adsorbing the aluminum curtain wall is rotated vertically, and the movable frame 2 is slid into the device frame 1. According to the installation position, the left and right positions of the aluminum curtain wall in the movable frame 2 are reasonably adjusted to correspond to the installation position. The limit block 7 is rotated out, and the limit block 7 is rotated into the positioning opening 102. The knob 14 is fixed on the rotating stud 13 to make it close to the surface of the limit block 7. The limit block 7 presses the surface of the positioning opening 102, thereby fixing the left and right positions of the movable frame 2 in the device frame 1, and realizing the determination of the left and right positions of the aluminum curtain wall;

[0044] Furthermore, referring to Figure 5 , 6 , the left and right sides of the center seat 301 are rotatably connected with regulating handles 302, and a torsion spring is arranged at the junction of the regulating handle 302 and the center seat 301. T-shaped rods 16 are slidably arranged on the left and right sides of the inner side of the middle frame 6, and a positioning block 15 is fixed on the outer end of the T-shaped rod 16. Positioning tooth seats 203 corresponding to the positioning block 15 are arranged on the left and right sides of the outer side of the movable frame 2. A tension spring 11 is connected between the T-shaped rod 16 and the movable frame 2, and the inner end of the T-shaped rod 16 corresponds to the regulating handle 302. After the above adjustment, the regulating handles 302 on both sides of the center seat 301 are opened, and the T-shaped rod 16 loses the restriction of the regulating handle 302. The tension spring 11 pulls the positioning block 15 connected to the T-shaped rod 16 to move to the left and right sides, and the positioning block 15 is separated from the positioning tooth seat 203. At this time, the entire longitudinal adjustment mechanism 3, the four-corner adjustment mechanism 5 and the upper and lower positions of the middle frame 6 in the movable frame 2 can be adjusted to correspond the upper and lower sides of the aluminum plate curtain wall to the installation position;

[0045] Furthermore, the center seat 301 and the spur gear 305 slide forward and backward on the limiting rod 8. Since the upper and lower cross frames 501 slide longitudinally inward and outward in the longitudinal seats 503 on both sides, and the center seat 301 and the entire longitudinal adjustment mechanism 3 slide longitudinally inward and outward on the limiting rod 8, when the above-mentioned two-side regulating handles 302 are opened, the longitudinal front and rear positions of the longitudinal adjustment mechanism 3 in the movable frame 2 and the four-corner adjustment mechanism 5 can be adjusted. Combined with the above, the aluminum plate curtain wall after the corresponding position is adjusted up, down, left, and right, and the adsorbed aluminum plate curtain wall is pushed into the corresponding installation groove. The control handle 302 is positioned so as to align it with the front and rear surfaces of the surrounding aluminum plate curtain wall, and then the handle is released. Due to the action of the torsion spring, the regulating handles 302 on both sides rotate, and the positioning block 15 connected to the T-shaped rod 16 is moved back. The positioning block 15 is inserted into the positioning tooth seat 203 at the corresponding position to fix the upper and lower positions. The corresponding surfaces of the T-shaped rod 16 and the regulating handle 302 are both provided with rough surfaces. Due to the high relative friction between the regulating handle 302 and the T-shaped rod 16, the front and rear positions of the aluminum plate curtain wall deep into the groove are relatively stable, and then the hot-melt welding of the aluminum plate curtain wall can be conveniently performed;

[0046] Furthermore, referring to Figure 1 , 2 The four corners of the device frame 1 are all provided with fixed corners 101, and a card slot is opened in the center of the fixed corner 101. The upper and lower outer sides of the device frame 1 are provided with mounting frames 4, and a vacuum pump 401 is installed in the middle of the mounting frame 4. The vacuum pump 401 is connected with two exhaust pipes, and the outer ends of the two exhaust pipes are connected with air cavity tanks 402. The inner side of the air cavity tank 402 is connected with a suction cup 403 through an air pipe. A card slot corresponding to the card shaft 1203 is opened in the center of the fixed corner 101, and the air pipe and the card slot are engaged between the air cavity tank 402 and the suction cup 403. Before all the above work is carried out, the device frame 1 must be stabilized on the curtain wall installation surface to fix it in an approximate position. According to the position of the fixed corner 101, the positions of the suction cups 403 on both sides of the installation frame 4 are adjusted, and the air pipe is inserted into the slot of the fixed corner 101, so that the suction cup 403 is close to the installation surface around the aluminum curtain wall, and the vacuum pump 401 is started to make the suction cup 403 negative pressure inside to complete the fixation of the device frame 1. This installation frame 4 structure is suitable for the fixed-point replacement and disassembly of a single worn-out aluminum curtain wall;

[0047] On the basis of the above, refer to Figure 8 A curtain wall aluminum plate hot-melt welding device also includes an installation frame 12, the installation frame 12 includes two fixing fixtures 1201, a sliding shaft 1204 is fixed between the two fixing fixtures 1201, and a sliding groove plate 1202 is slidably provided at both ends of the sliding shaft 1204. Two clamping shafts 1203 that slide up and down are arranged in the sliding groove plate 1202. A screw is fixed at the inner end of the clamping shaft 1203. The outer thread of the screw is connected with a nut that is close to the inner side of the fixed corner 101. Replace the installation frame 14 with the installation frame 12, find the installation frame and the installation position, and fix the fixture 12 01 to achieve the fixation of the overall mechanism. The fixing clamp 1201 is a conventional device, usually a spring clamp or a threaded clamp, which can be fixed on the curtain wall frame. According to the position of the fixed corner 101, the left and right positions of the slide plates 1202 on both sides of the sliding shaft 1204 are reasonably adjusted, and its internal clamping shaft 1203 is clamped into the corresponding clamping groove of the fixed corner 101, and the approximate position of the device frame 1 is adjusted.
