[0041] like Figure 4 、 Figure 9 As shown, the upper side of the sliding plate 303 is slidably connected to the limiting plate 308, and four blind holes are opened on the side of the limiting plate 308.

[0045] Working principle: When the door and window frames need to be welded, the welding length needs to be adjusted first. When the spacing needs to be lengthened, the first motor 201 is first started through the control box 5, and the output end shaft drives the active bevel gear 202 to rotate clockwise. The active bevel gear 202 drives the driven bevel gears 203 on both sides to rotate counterclockwise through the meshing connection relationship, thereby driving the screw 204 to rotate counterclockwise, and drives the two threaded blocks 205 to move away from the driven bevel gear 203 through the thread, so that the support slider 210 on the upper side of the threaded block 205 moves in the same direction. At this time, the support slider 210 moves along the outside of the first positioning shaft 206 and the second positioning shaft 207 on both sides, and at the same time drives the sliding plate 303 to move in the same direction through the limit slider 310, so as to lengthen the distance between the platforms. When the spacing needs to be reduced, the motor is started in the reverse direction to reduce the spacing.

[0046] After the spacing is adjusted, the long side window frame 307 is placed on the upper side of the sliding plate 303. At this time, the long side window frame 307 will press the trigger plate 309 downward, and the trigger plate 309 will move downward, and the inclined surface of the lower half of the trigger plate 309 will drive the limit shaft 312 to move away from the limit plate 308. At the same time, the limit shaft 312 releases the restriction on the limit plate 308. At this time, the limit plate 308 moves upward under the action of the first return spring 311 and extends out of the sliding plate 303. At this time, the limit plate 308 and the limit block 304 above the sliding plate 303 are in a state of tension. Angle, place the short side window frame 306 above the fixed block 302 along the angle between the limit plate 308 and the limit block 304, and then start the hydraulic box 401 through the control box 5, thereby extending the hydraulic telescopic rod 402 on the lower side of the hydraulic box 401, thereby driving the telescopic plate 403 to move downward, and at the same time drive the fixed splint 404, the sliding splint 405 and the sliding heating plate 406 to move downward synchronously. At this time, the fixed splint 404 will press against the short side window frame 306, and the sliding splint 405 will press against the long side window frame 307, so as to realize the positioning and fixation of the long side window frame 307 and the short side window frame 306.

[0047] After fixing the long side window frame 307 and the short side window frame 306, the sliding heating plate 406 is driven downward by the hydraulic box 401, and the limit plate 308 is pressed to the inside of the sliding plate 303, and stays on the inside of the sliding plate 303 under the action of the limit shaft 312. At this time, the sliding heating plate 406 stays between the long side window frame 307 and the short side window frame 306. At this time, the second motor 301 is started by the control box 5, and the second motor 301 drives the rotating shaft 305 to rotate clockwise. Under the action of the cylindrical slider and the slide groove between the rotating shaft 305 and the sliding plate 303, the rotating shaft 305 drives the sliding plate 303 to move toward the second motor 301. At this time, the sliding plate 303 drives the long side window frame 307 and the sliding clamp 405 to move in the same direction, thereby heating the welding surface of the long side window frame 307 and the short side window frame 306.

[0048] After the heating is completed, the second motor 301 is started in reverse and the sliding heating plate 406 is raised. At this time, the second motor 301 is started again to splice the long side window frame 307 and the short side window frame 306. After a fixed time, the hydraulic telescopic rod 402 is raised upward and at the same time drives the fixed splint 404, the sliding splint 405 and the sliding heating plate 406 to rise upward, releasing the restrictions on the long side window frame 307 and the short side window frame 306, and the second motor 301 is started in reverse again to reset the sliding plate 303 to achieve the welding of the long side window frame 307 and the short side window frame 306.

[0049] During the welding process of the long side window frame 307 and the short side window frame 306, when the hydraulic telescopic rod 402 drives the fixed splint 404, the sliding splint 405 and the sliding heating plate 406 to rise upward, the telescopic plate 403 will drive the sliding connecting plate 407 to move synchronously, and at the same time drive the first sliding rack 408 to move upward, and the first sliding rack 408 drives the first matching gear 409 to rotate clockwise through the meshing relationship, and the first matching gear 409 drives the second sliding rack 410 to slide counterclockwise through the meshing relationship. At this time, the second sliding rack 410 drives the second matching gear 411 to rotate clockwise, and drives the third sliding rack 412 to move toward the sliding plate 303 through the second matching gear 411, and pushes the moving baffle 415 to move in the same direction. At the same time, the moving baffle 415 pushes the long side window frame 307 and the short side window frame 306 after the welding is completed to move in the same direction, thereby realizing the ejection of the long side window frame 307 and the short side window frame 306.

[0050] When the long side window frame 307 and the short side window frame 306 are pushed out, the telescopic plate 403 under the hydraulic box 401 is at the highest point. At this time, the telescopic plate 403 is controlled by the control box 5 to move downward, and drives the sliding connecting plate 407 to move downward, and at the same time drives the first sliding rack 408 to move downward and causes the first matching gear 409 to rotate counterclockwise, and drives the second matching gear 411 to rotate counterclockwise through the second sliding rack 410, and at the same time drives the third sliding rack 412 to move away from the sliding plate 303, and drives the moving baffle 415 to move in the same direction, thereby realizing the resetting of the moving baffle 415.

[0052] S1, start the first motor 201, drive the driving bevel gear 202 to rotate through the output end shaft, and at the same time drive the driven bevel gears 203 on both sides to rotate through the meshing connection relationship, thereby driving the threaded block 205 to move away from the driven bevel gear 203 through the thread meshing relationship, thereby lengthening the distance between the platforms, and starting the motor in the reverse direction to reduce the distance;

[0053] In step S2, the long-side window frame 307 presses the trigger plate 309 downward, and the trigger plate 309 drives the limit shaft 312 to release the limit plate 308. At the same time, the return spring pushes the limit plate 308 upward and extends the sliding plate 303, placing the short-side window frame 306 above the fixed block 302. At this time, the hydraulic box 401 is activated by the control box 5 to drive the fixed clamping plate 404, the sliding clamping plate 405 and the sliding heating plate 406 to move downward and press against the window frame, thereby achieving the positioning and fixing of the long-side window frame 307 and the short-side window frame 306.

[0054] S3, the control box 5 drives the sliding heating plate 406 to move downward, and at this time the control box 5 starts the second motor 301, which drives the sliding plate 303 to move toward the second motor 301, driving the long side window frame 307 and the sliding clamping plate 405 to move in the same direction, thereby heating the welding surface of the long side window frame 307 and the short side window frame 306;

[0055] S4, reversely start the second motor 301 and raise the sliding heating plate 406, then start the second motor 301 again to splice the long side window frame 307 and the short side window frame 306, and after a fixed time, raise the hydraulic telescopic rod 402 upward to release the restriction on the long side window frame 307 and the short side window frame 306, thus completing the welding of the long side window frame 307 and the short side window frame 306;

[0056] S5, the hydraulic telescopic rod 402 drives the telescopic plate 403 and the sliding connecting plate 407 to move upward, and at the same time drives the first matching gear 409 to rotate through the meshing relationship. At the same time, the first sliding rack 408 drives the third sliding rack 412 to move toward the sliding plate 303 through the meshing relationship. At the same time, the moving baffle 415 pushes the welded long side window frame 307 and the short side window frame 306 to move in the same direction after a certain delay, so as to push out the long side window frame 307 and the short side window frame 306;

[0057] S6, the telescopic plate 403 is controlled to move downward through the control box 5, and the sliding connecting plate 407 is driven to move downward, while the first sliding rack 408 is driven to move downward and the third sliding rack 412 is driven to move away from the sliding plate 303 through the meshing relationship, and the moving baffle 415 is driven to move in the same direction, thereby realizing the resetting of the moving baffle 415.
