The top plate 4 is U-shaped, and the top plate 4 is clamped on the upper ends of the two support plates 3. Bolts pass through the left and right ends of the top plate 4 and the upper side walls of the support plates 3 to fix the top plate 4.

[0028] Chute 1 5 is provided at the upper ends of the two support plates 3, and a rotating rod 2 9 is slidably connected in the chute 1 5. The diameter of the rotating rod 2 9 is greater than the width of the chute 1 5. Connecting grooves 10 are symmetrically provided on the outer walls of the left and right ends of the rotating rod 2 9, and the outer walls of the connecting grooves 10 are slidably connected to the inner walls of the chute 1 5 to limit the rotating rod 2 9 so that it can only slide up and down in the chute 1 5.

[0029] A rotating rod 1 8 is rotatably connected between the two support plates 3. The rotating rod 1 8 is located directly below the rotating rod 2 9. Gears 33 are fixedly installed at the left and right ends of the rotating rod 1 8, and sprockets 2 19 are fixedly installed on the outer walls of the left and right ends of the rotating rod 2 9. The gears 33 and the sprockets 2 19 are located outside the support plates 3.

[0030] One end of two support plates 3 is provided with a second chute 6. A round rod 14 is elastically connected in the second chute 6. Both the left and right ends of the round rod 14 are rotatably connected with a first sprocket 18. The lower end of a gear 33 is provided with a third sprocket 32. The third sprocket 32 is rotatably connected to the side wall of the support plate 3 through a rotating shaft. A gear 33 is fixedly installed inside the third sprocket 32. The outer walls of the two gears 33 are meshed with each other. The first sprocket 18 is located outside the support plate 3 and is on the same horizontal line as the second sprocket 19 and the third sprocket 32. A chain 20 is connected to the outer ends of the first sprocket 18, the second sprocket 19 and the third sprocket 32. One end of the first rotating rod 8 away from the pressing roller 23 is fixedly installed with a crank 21. By rotating the crank 21, the first rotating rod 8 can be driven to drive the gear 33 to rotate. The gear 33 drives the third sprocket 32 to rotate. The third sprocket 32 drives the second sprocket 19 and the first sprocket 18 to rotate through the chain 20. At the same time, the gear 33 drives the first rotating rod 8 to rotate, so as to drive the first rotating rod 8 and the second rotating rod 9 to rotate synchronously. The first rotating rod 8 and the second rotating rod 9 drive the pressing roller 23 to rotate, and the pattern of the edge wrapping part of the circular arched skylight can be extruded and formed.

[0031] Limiting grooves 7 are respectively opened on the inner walls of the upper and lower ends of the second chute 6. Sliders 15 are symmetrically and fixedly installed on the outer walls of the left and right ends of the round rod 14. Limiting columns 16 are fixedly installed at the upper and lower ends of the slider 15. When the slider 15 slides into the second chute 6, the limiting column 16 slides into the limiting groove 7. The inner end of the slider 15 is fixedly installed with a first spring 17. The inner end of the first spring 17 is fixedly installed on the inner end wall of the second chute 6. When the chain 20 is connected to the outer walls of the first sprocket 18, the second sprocket 19 and the third sprocket 32, the first spring 17 is in a compressed state. The first spring 17 applies an outward thrust to the first sprocket 18, so that the chain 20 can always be connected to the outer walls of the first sprocket 18, the second sprocket 19 and the third sprocket 32.

[0032] The upper end of the second rotating rod 9 is connected with a driving component. The driving component includes a threaded rod 11 threadedly connected to the upper end of the top plate 4. The lower end of the threaded rod 11 passes through the top plate 4 and is rotatably connected with a push plate 12. The push plate 12 is U-shaped. The left and right sides of the lower end of the push plate 12 are rotatably connected to the left and right ends of the second rotating rod 9 through bearings 13. By rotating the threaded rod 11, the push plate 12 can be driven to drive the second rotating rod 9 to move, so as to change the distance between the two pressing rollers 23, and the pattern of the edge wrapping part of the circular arched skylight with different thicknesses can be extruded and formed.

[0033] One end of the first rotating rod 8 and the second rotating rod 9 is detachably installed with a pressure roller 23. One end of the first rotating rod 8 and the second rotating rod 9 is fixedly installed with a baffle 22. The baffle 22 is located outside the second sprocket 19. Symmetrically fixed on the outer side of one end of the first rotating rod 8 and the second rotating rod 9 are strip-shaped blocks 24. The strip-shaped blocks 24 are located outside the baffle 22. Symmetrically formed on the inner end of the pressure roller 23 are strip-shaped grooves 25. When the pressure roller 23 is sleeved on the outer wall of the first rotating rod 8 or the second rotating rod 9, the strip-shaped blocks 24 slide and insert into the strip-shaped grooves 25 to prevent the pressure roller 23 from rotating on the outer wall of the first rotating rod 8 or the second rotating rod 9.

[0034] Symmetrically fixed on the outer side of one end of the first rotating rod 8 and the second rotating rod 9 are fixed blocks 26. Both the upper and lower ends of the fixed blocks 26 are provided with fixing grooves 27. Slidingly inserted into each fixing groove 27 is a moving block 30. Fixedly installed at the lower end of each moving block 30 is a second spring 31. The other end of the second spring 31 is fixed on the bottom inner wall of the fixing groove 27. When the second spring 31 is in a balanced state, the moving block 30 is located outside the fixing groove 27, and the moving block 30 can move in the fixing groove 27 by compressing the second spring 31.

[0035] The outer sides of one end of the first rotating rod 8 and the second rotating rod 9 are both sleeved with metal rings 29. Fixedly installed on the inner side of the metal rings 29 are rubber pads 28. The rubber pads 28 are in contact with the outer side wall of the end of the pressure roller 23. When the moving block 30 is located outside the metal ring 29, one end of the pressure roller 23 abuts against the baffle 22, and the other end of the pressure roller 23 is in close contact with the rubber pad 28 to fix the pressure roller 23. When it is necessary to replace the pressure roller 23 with different patterns, the moving block 30 is pushed inward, and the pressure roller 23 can be removed, which facilitates the disassembly and assembly of the pressure roller 23.

[0036] When the device works, the second rotating rod 9 is driven to move by rotating the threaded rod 11, so as to adjust the distance between the two pressure rollers 23 to the position required for use. Then, one end of the edging part of the arched skylight is inserted into the two pressure rollers 23. By rotating the crank 21, the first rotating rod 8 can be driven to drive the gear 33 to rotate. The gear 33 drives the third sprocket 32 to rotate. The third sprocket 32 drives the second sprocket 19 and the first sprocket 18 to rotate through the chain 20. At the same time, the gear 33 drives the first rotating rod 8 to rotate, so as to drive the first rotating rod 8 and the second rotating rod 9 to rotate synchronously. The first rotating rod 8 and the second rotating rod 9 drive the pressure roller 23 to rotate, and the pattern of the edging part of the arched skylight can be extruded and formed.
