Description

[0002] Aluminum formwork, also known as aluminum alloy formwork for construction, is a new generation of formwork system that emerged after wooden and steel formwork. Designed modularly and manufactured using specialized equipment, aluminum formwork can be freely combined to accommodate different structural dimensions. It primarily uses aluminum alloy profiles, manufactured through machining and welding processes. The modular design comprises panels, ribs, main profiles, flat formwork, corner formwork, and early stripping devices. C-groove formwork is used at wall corners and where floors intersect with wall panels.

[0066] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0067] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0068] Please refer to Figure 1. The system for punching C-slot profiles includes a sawing device 1 for sawing C-slot profiles to a target length, a first punching device 2, a flipping device 3 whose feed end is connected to the discharge end of the first punching device 2, a first conveying device 4 whose feed end is connected to the discharge end of the flipping device 3, and a second punching device 5 whose feed end is connected to the discharge end of the first conveying device 4.

[0069] During the sawing and punching process of the C-slot template, the C-slot profile is sawn to the target length by the sawing device 1 and then fed into the first punching device 2. After entering the first punching device 2, the C-slot profile completes the punching of one unequal side. Then, the C-slot profile enters the flipping device 3 to be flipped. The flipped C-slot profile is then fed into the second punching device 5 by the first conveying device 4, where the punching of the other unequal side is completed. The sawing device 1 and the first punching device 2 can be integrated into one unit, with the C-slot profile cut to the target length being fed into the first punching device 2 via a conveyor. Alternatively, the sawing device 1 and the first punching device 2 can be set up separately, with the C-slot profile cut to the target length being stored and transferred before being sent into the first punching device 2.

[0070] Based on this, the punching of both sides of the C-slot profile, as well as the flanging and conveying functions between the two punching operations, are integrated into one, realizing continuous and automated production of C-slot profile punching. This helps to reduce labor intensity, improve work efficiency, and ensure and improve work accuracy.

[0071] Please refer to Figures 2 to 7. In this embodiment, both the first punching device 2 and the second punching device 5 include a first frame 6, a crossbeam 7 connected to the first frame 6, a plurality of punching fixed dies 8 connected to the crossbeam 7, a plurality of pressing mechanisms 9 connected to the crossbeam 7, a plurality of punching moving die mechanisms 10 connected to the first frame 6, a truss 11 connected to the first frame 6, a mounting plate 12 slidably connected to the truss 11, a propulsion mechanism 13 that pushes the mounting plate 12 to move along the truss 11, a first telescopic mechanism 14 connected to the mounting plate 12, a second telescopic mechanism 15 connected to the telescopic rod of the first telescopic mechanism 14, a hook 16 connected to the telescopic rod of the second telescopic mechanism 15, a sensor 17 connected to the mounting plate 12, and a lifting conveyor roller 18 connected to the first frame 6. Please refer to Figures 8 and 9. The punching moving die mechanism 10 includes a moving die frame 19 slidably connected to the first frame 6, a hydraulic cylinder 20 that pushes the moving die frame 19 to reciprocate, and a plurality of punching moving dies connected to the moving die frame 19. The punching moving die includes a punch guide hole and a pad groove 21 provided on the moving die frame 19, a punch 22 slidably connected to the punch guide hole, a first pad 23 and a second pad 24 inserted into the pad groove 21, a first hole and a second hole provided in the second pad 24, and a punch 22 installed on the first... The device includes a first spring 25 inside a hole, a positioning bead 26 located near the end of the first pad 23 inside the first hole, a second spring 27 installed in the second hole, and a pusher 28 located near the end of the first pad 23 in the second hole and slidably connected to the second pad 24. The first pad 23 has two grooves 29 that cooperate with the positioning bead 26 to fix the first pad 23 after it is pulled out or inserted. The first pad 23 has a lever 30 for inserting the hook 16 and a clearance groove for the pusher 28 to pass through. In this embodiment, the clamping mechanism 9 is preferably a cylinder.

[0072] Different batches of C-slot templates may have different punching spacing and positions. When it is necessary to change the punching hole spacing and position, the technical solution in this embodiment designs a punching fixed die 8 and a punching moving die with more punching holes than the actual number of punching holes on the first punching device 2 and the second punching device 5. As shown in Figures 4 to 9, the push mechanism 13 is activated to move the mounting plate 12 to the front of the punch that needs to be adjusted. The second telescopic mechanism 15 drives the hook 16 to align with the position of the lever 30. Then the first telescopic mechanism 14 is activated to drive the hook 16 to hook into the lever 30. The extension and retraction of the second telescopic mechanism 15 pushes or pulls out the first pad 23. When the first pad 23 is pulled out, during punching, the punch 22 resists the push 28 to squeeze the second spring 27 and retreats against the elastic force of the second spring 27. The corresponding punch cannot complete the punching process. However, when the first pad 23 is pushed in, the first pad 23 blocks the punch 22 from retreating, and the corresponding punch completes the punching operation during the punching process. After the first pad 23 is pushed or pulled out, the first telescopic mechanism 14 is activated. The first telescopic mechanism 14 drives the second telescopic mechanism 15 and the hook 16 to descend, so that the hook 16 is separated from the lever 30. The second telescopic mechanism 15 retracts and pulls the hook 16 to the position near the truss 11. The pushing mechanism 13 is activated and drives the mounting plate 12 to move in front of the next punch that needs to be adjusted. The operation is repeated until the position of all the first pads 23 is adjusted to meet the position and spacing requirements of the punching.

[0073] Based on this, by adjusting the position of the first pad 23, the first punching device 2 and the second punching device 5 can automatically adjust the punching hole spacing and punching position, thereby solving the problem of inconvenience in adjusting the spacing and punching position between punches in the prior art, and flexibly adapting to the punching number and spacing requirements of the C-groove template.

[0074] Please refer to Figure 10. In this embodiment, the lifting conveyor roller conveyor 18 includes a second frame 77, a first lifting frame 78 slidably connected to the second frame 77, a plurality of first rollers 79 connected to the first lifting frame 78, a first screw jack 80 and a second screw jack 81 whose body is connected to the second frame 77 and whose screw end is connected to the first lifting frame 78, and a drive mechanism 82 that is kinetically connected to the input shaft of the first screw jack 80 and the input shaft of the second screw jack 81.

[0075] Please refer to Figures 5 and 6. The C-slot profile has an unequal side structure, and the crossbeam 7 is provided with a U-shaped groove for inserting the unequal side of the C-slot profile. Please refer to Figure 3. The punching die 8 is located on the lower side of the U-shaped groove of the crossbeam 7. During operation, after one unequal side of the C-slot profile is fed into the U-shaped groove, the piston rod of the clamping mechanism 9 extends to clamp and fix the C-slot profile. Then, the punching moving die mechanism 10 is activated to complete the punching operation on one unequal side of the C-slot profile. During punching, the other unequal side of the C-slot profile is supported by the lifting conveyor roller 18, and the lifting conveyor roller 18 completes the conveying of the C-slot profile. Therefore, when punching the two unequal sides, the distance between the roller surface of the lifting conveyor roller 18 and the punching die 8 is different. The first screw jack 80 and the second screw jack 81 drive the first lifting frame 78 to rise and fall, thereby enabling convenient adjustment of the distance between the roller surface of the lifting conveyor roller 18 and the punching die 8, so that one unequal side of the C-shaped groove profile fits onto the punching die 8 during the punching process.

[0076] Referring to Figure 11, in this embodiment, the lifting conveyor roller 18 further includes a plurality of fixed slide plates 83 connected to the first side of the second frame 77, a plurality of first sliding plates 84 connected to the first lifting frame 78 and slidably connected to the fixed slide plates 83, a plurality of adjusting screws 85 connected to the other side of the second frame 77, a movable slide plate 86 connected to the adjusting screws 85, and a plurality of second sliding plates 87 connected to the first lifting frame 78 and slidably connected to the movable slide plates 86.

[0077] The distance between the movable slide plate 86 and the fixed slide plate 83 can be adjusted by rotating the adjusting screw 85, thereby maintaining an appropriate gap between the fixed slide plate 83 and the first sliding plate 84, and between the movable slide plate 86 and the second sliding plate 87, to prevent the first lifting frame 78 from swinging too much during operation, while ensuring smooth lifting.

[0078] Referring to Figure 7, in this embodiment, both the first punching device 2 and the second punching device 5 also have a nozzle 130 connected to the mounting plate 12. The nozzle 130 is connected to a lubricating oil pipe to provide lubricating oil to the punching die during punching, thereby improving the service life of the punching die and the smoothness of the punching.

[0079] Please refer to Figure 5. In this embodiment, both the first punching device 2 and the second punching device 5 also have a third cylinder 131 connected to the crossbeam 7.

[0080] When the piston rod of the third cylinder 131 extends, its front end enters the U-shaped groove of the crossbeam 7, blocking the passage of the C-shaped profile. When the piston rod of the third cylinder 131 retracts, its front end exits from the U-shaped groove of the crossbeam 7, allowing the C-shaped profile to pass through. Based on this, the third cylinder 131 can achieve the positioning function of the C-shaped profile. When one end of the C-shaped profile reaches the piston rod of the third cylinder 131, the C-shaped profile is precisely positioned, thereby making the punching position more accurate.

[0081] Please refer to Figures 6 and 7. In this embodiment, the propulsion mechanism 13 includes a first guide rail 132 and a first rack 133 connected to the truss 11, a first servo motor 134 connected to the mounting plate 12, and a first gear 135 that is driven by the first servo motor 134 and meshes with the first rack 133; the mounting plate 12 is slidably connected to the first guide rail 132.

[0082] The first servo motor 134 drives the mounting plate 12 to move along the first guide rail 132 through a gear and rack mechanism. By controlling the first servo motor 134, the amount of movement of the mounting plate 12 can be controlled, thereby controlling the amount of movement of the hook 16 and realizing the positioning of the hook 16.

[0083] Referring to Figure 2, in this embodiment, the punching moving die mechanism 10 further includes a fixed guide rail 136 connected to the first frame 6, and a movable guide rail 137 slidably connected to the fixed guide rail 136; the moving die frame 19 is connected to the movable guide rail 137. The moving die frame 19 is slidably connected to the first frame 6 through the movable guide rail 137 and the fixed guide rail 136. The movable guide rail 137 and the fixed guide rail 136 adopt a trapezoidal structure, and one of them is adjustable in installation position during manufacturing, which facilitates adjustment of the distance between the movable guide rail 137 and the fixed guide rail 136, thereby reducing maintenance costs.

[0084] Referring to Figures 12 and 13, in this embodiment, the sawing device 1 includes a third frame 31, a second conveying device 32 connected to one side of the third frame 31, a base plate 33 connected to the third frame 31, a positioning seat 34 connected to the third frame 31, a first side-pressing mechanism 35 and at least one set of second side-pressing mechanisms 36 connected to the third frame 31, a pressing mechanism 37 connected to the third frame 31, a sawing machine 38 slidably connected to the third frame 31, and a drive mechanism for reciprocating the sawing machine 38. The second side-pressing mechanisms 36 are located on both sides of the sawing machine 38 blade.

[0085] In continuous production, the C-slot profile is fed into the sawing device 1, cut by the sawing machine 38, and then enters the second conveying device 32, realizing continuous sawing and punching operations. The first side pressing mechanism 35 and the second side pressing mechanism 36 can push the C-slot profile towards the positioning seat 34 and press it in a direction parallel to the base plate 33. The lower pressing mechanism 37 can press the C-slot profile in a direction perpendicular to the base plate 33. The drive mechanism drives the sawing machine 38 to move forward or backward. When moving forward, the sawing machine 38 cuts the C-slot profile. When moving backward, the saw blade of the sawing machine 38 leaves the C-slot profile, realizing the blade retraction operation. During sawing, the first side pressing mechanism 35, the second side pressing mechanism 36, and the lower pressing mechanism 37 press the C-slot profile. When the C-slot profile needs to be moved, the first side pressing mechanism 35, the second side pressing mechanism 36, and the lower pressing mechanism 37 release the C-slot profile. Based on this, when the sawing machine 38 is sawing C-slot profiles, it can fix the C-slot profiles, prevent them from moving and bouncing, and prevent damage to the saw blade. When the C-slot profiles need to be moved, the movement of the C-slot profiles can be easily realized.

[0086] Referring to Figures 14 and 15, in this embodiment, the sawing device 1 further includes a second guide rail 39 connected to the third frame 31, a sawing machine base 40 slidably connected to the second guide rail 39, and a sawing machine 38 connected to the sawing machine base 40. The driving mechanism includes a second rack 41 connected to the third frame 31, a second servo motor 42 connected to the sawing machine base 40, and a second gear that is driven by the second servo motor 42 and meshes with the second rack 41. The sawing machine base 40 and the sawing machine 38 move along the second guide rail 39, and the second servo motor 42 drives the sawing machine 38 forward or backward through the gear and rack mechanism to realize the sawing operation.

[0087] Referring to Figure 12, in this embodiment, the second conveying device 32 includes a fourth frame 43, a plurality of second rollers 44 connected to the fourth frame 43, a plurality of positioning and clamping mechanisms 45 connected to the fourth frame 43, a first lifting mechanism 46 and a second lifting mechanism 47 connected to the fourth frame 43, a third guide rail 48 and a third rack 49 connected to the fourth frame 43, a first clamp 50 connected to the third guide rail 48, a third servo motor 51 connected to the first clamp 50, and a third gear that is drivenly connected to the third servo motor 51 and meshes with the third rack 49.

[0088] When the C-shaped channel profile is placed onto the second conveying device 32, the first lifting mechanism 46 and the second lifting mechanism 47 rise to facilitate the acceptance of the C-shaped channel profile. After the C-shaped channel profile is placed onto the first lifting mechanism 46 and the second lifting mechanism 47, the first lifting mechanism 46 and the second lifting mechanism 47 descend, and the C-shaped channel profile falls onto the second roller 44. The first clamp 50 clamps the end of the C-shaped channel profile away from the sawing machine 38. After the first clamp 50 pushes the C-shaped channel profile to the first sawing position, the positioning and clamping mechanism 45 corrects the position of the C-shaped channel profile and clamps it to fix the C-shaped channel profile. For the structure and working principle of the first clamp 50, please refer to the "A Traction Pushing Device" disclosed in Chinese Patent Publication No. CN218487849U.

[0089] Please refer to Figure 19. In this embodiment, the positioning and clamping mechanism 45 includes a mounting bracket 52 connected to the fourth frame 43, a first roller 53 connected to the first end of the mounting bracket 52, a fourth guide rail 54 connected to the mounting bracket 52, a second roller 55 slidably connected to the fourth guide rail 54, and a third telescopic mechanism 56 connected to the mounting bracket 52 and the telescopic rod connected to the second roller 55.

[0090] The extension and retraction of the third telescopic mechanism 56 drives the second roller 55 to move along the fourth guide rail 54, realizing the release and clamping of the C-slot profile. When the third telescopic mechanism 56 retracts, the second roller 55 pushes the C-slot profile against the first roller 53. The fixed position of the first roller 53 positions the C-slot profile, thereby realizing the function of clamping and positioning the C-slot profile by the positioning and clamping mechanism 45. After the positioning and clamping mechanism 45 clamps the C-slot profile, the first roller 53 and the second roller 55 enable the C-slot profile to move axially, facilitating the first clamp 50 to push the C-slot profile to complete the feeding operation.

[0091] Please refer to Figure 20. In this embodiment, both the first lifting mechanism 46 and the second lifting mechanism 47 include a lifting seat 57 connected to the fourth frame 43, a first cylinder 58 connected to the base and the lifting seat 57, and a receiving plate 59 connected to the piston rod of the first cylinder 58.

[0092] When the piston rod of the first cylinder 58 extends, the receiving plate 59 rises, its height exceeding that of the second roller 44, facilitating the acceptance of the C-groove profile. When the piston rod of the first cylinder 58 retracts, the receiving plate 59 descends, its height falling below that of the second roller 44, allowing the C-groove profile to slide on the second roller 44, thus facilitating the pushing by the first clamp 50.

[0093] Referring to Figure 15, in this embodiment, the sawing device 1 further includes a side suction pipe 60 connected to the third frame 31 and a bottom suction pipe 61 connected to the sawing machine base 40. The sawing machine 38 is equipped with a protective cover, which closes the sawing area. The side suction pipe 60 and the bottom suction pipe 61 are connected to an external negative pressure system, using negative pressure to promptly discharge sawdust.

[0094] Please refer to Figure 16. In this embodiment, the first side pressure mechanism 35 includes a first linear bearing 62 connected to the third frame 31, a fourth telescopic mechanism 63 connected to the base and the third frame 31, a first guide rod 64 connected to the first linear bearing 62, a first side pressure plate 65 connected to one end of the first guide rod 64 and the telescopic rod of the fourth telescopic mechanism 63, and a plurality of third rollers 66 connected to the first side pressure plate 65.

[0095] The fourth telescopic mechanism 63 drives the first guide rod 64 and the first side pressure plate 65 to move. The fourth telescopic mechanism 63 extends, and the third roller 66 reaches the C-shaped channel profile and presses it. The third roller 66 contacts the C-shaped channel profile, facilitating axial movement of the C-shaped channel profile when the fourth telescopic mechanism 63 is not depressurized.

[0096] Please refer to Figure 17. In this embodiment, the second side pressure mechanism 36 includes a second linear bearing 67 connected to the third frame 31, a fifth telescopic mechanism 68 connected to the base and the third frame 31, a second guide rod 69 connected to the second linear bearing 67, a second side pressure plate 70 connected to one end of the second guide rod 69 and the telescopic rod of the fifth telescopic mechanism 68, and a pad 71 connected to the second side pressure plate 70.

[0097] The fifth telescopic mechanism 68 drives the second guide rod 69, the second side pressure plate 70, and the pad 71 to move. The fifth telescopic mechanism 68 extends, and after the pad 71 reaches the C-shaped channel profile, it presses the C-shaped channel profile. The pad 71 is preferably made of polyurethane material. The pad 71 is elastic, and based on this, the pad 71 has a cushioning function when in contact with the C-shaped channel profile, and the pad 71 can better fit with the C-shaped channel profile.

[0098] Please refer to Figure 18. In this embodiment, the pressing mechanism 37 includes a pressing mechanism seat 72 connected to the third frame 31, a third linear bearing 73 connected to the pressing mechanism seat 72, a sixth telescopic mechanism 74 connected to the base and the pressing mechanism seat 72, a third guide rod 75 connected to the third linear bearing 73, and a pressing plate 76 connected to one end of the third guide rod 75 and the telescopic rod of the sixth telescopic mechanism 74.

[0099] The two ends of the pressure plate 76 have unequal heights, which are used to contact the long and short sides of the C-channel profile, respectively. The bottom of the pressure plate 76 is also provided with a polyurethane block, which makes the bottom of the pressure plate 76 elastic. Based on this, the pressure plate 76 has a buffering function when contacting the C-channel profile, and the pressure plate 76 can better fit the C-channel profile.

[0100] Please refer to Figures 1 and 21. In this embodiment, a feeding device 88 is also provided for feeding the sawing device 1. The feeding device 88 includes a material rack 89 located on one side of the sawing device 1, and a first feeding assembly 90 and a second feeding assembly 91 located on the outer sides of both ends of the material rack 89. Please refer to Figures 22 to 25. Both the first feeding assembly 90 and the second feeding assembly 91 include a base frame 92, fifth guide rails 93 connected to both ends of the base frame 92, a fourth rack 94 connected to the base frame 92, a bracket 95 slidably connected to the fifth guide rail 93, a fourth servo motor 96 connected to the bracket 95, a fourth gear drivenly connected to the fourth servo motor 96 and meshing with the fourth rack 94, a sixth guide rail 97 and a fifth rack 98 connected to the bracket 95, a lifting bracket 99 slidably connected to the sixth guide rail 97, and a connecting rod connected to the lifting bracket 99. The fifth servo motor 100, the fifth gear connected to the fifth servo motor 100 and meshing with the fifth rack 98, the sixth servo motor 101 connected to the lifting bracket 99, the ball screw 102 connected to the lifting bracket 99 and connected to the sixth servo motor 101, the seventh guide rail 103 connected to the lifting bracket 99, the mounting base 104 slidably connected to the seventh guide rail 103 and connected to the ball screw 102, the rotating mechanism 105 connected to the mounting base 104, and the second clamp 106 connected to the rotating mechanism 105.

[0101] The fourth servo motor 96 drives the bracket 95 to move along the fifth guide rail 93, aligning the second clamp 106 with both ends of the C-shaped channel profile stacked on the storage rack 89. The fifth servo motor 100 drives the lifting bracket 99 to move, causing the second clamp 106 to move closer to or further away from the storage rack 89, ensuring the distance between the second clamp 106 and the end of the C-shaped channel profile meets the clamping requirements. The sixth servo motor 101 pushes the mounting base 104 up and down via the ball screw 102, thereby moving the second clamp 106 up and down, adapting the height of the second clamp 106 to the C-shaped channel profile stacked on the storage rack 89. During loading, after adjusting the position and height of the second clamp 106, the fifth servo motor 100 drives the lifting bracket 99 to move, causing the second clamp 106 to move towards the C-shaped channel profile, ensuring the distance between the second clamp 106 and the end of the C-shaped channel profile meets the clamping requirements. Based on this, the position of the second clamp 106 can be easily adjusted to meet the requirements of the position, height, and distance between the second clamp 106 and the C-slot profile during clamping. During storage and transportation, the two unequal sides of the C-slot profile are placed alternately. The rotating mechanism 105 can drive the second clamp 106 to rotate, thereby adjusting the orientation of the second clamp 106 and the C-slot profile it grips. This facilitates adjusting the orientation of the two unequal sides of the C-slot profile during loading to meet the requirements of processing.

[0102] Please refer to Figures 1 and 29. In this embodiment, a third conveying device 107 is also provided, with the feeding end connected to the discharge end of the sawing device 1 and the discharge end connected to the first punching device 2. The third conveying device 107 includes a fifth frame 108, a conveyor 109 connected to the fifth frame 108, and a first traction machine 110 connected to the fifth frame 108.

[0103] Referring to Figure 29, in this embodiment, the third conveying device 107 further includes a conveyor belt 111 connected to the fifth frame 108 for conveying sawn tailings. The sawn tailings are conveyed to a storage box via the conveyor belt 111.

[0104] Please refer to Figures 27 and 28. In this embodiment, the flipping device 3 includes a sixth frame 112, several third rollers 113 connected to the sixth frame 112, a flipping frame 114 hinged to the sixth frame 112, a seventh telescopic mechanism 115 with both ends hinged to the sixth frame 112 and the flipping frame 114 respectively, and a conveying baffle plate 116 connected to the sixth frame 112.

[0105] The middle part of the tilting frame 114 is hinged to the sixth frame 112. The seventh telescopic mechanism 115 drives the tilting frame 59 to rotate, thereby causing the C-shaped channel profile to be tilted. The conveying baffle plate 63 plays a blocking and positioning role.

[0106] Please refer to Figure 26. In this embodiment, the first conveying device 4 includes a seventh frame 117, a lifting roller conveyor 118 connected to the seventh frame 117, and a second traction machine 119 connected to the seventh frame 117. The lifting roller conveyor 118 includes a second lifting frame 120 slidably connected to the seventh frame 117, a plurality of fourth rollers 121 connected to the second lifting frame 120, a first lifting mechanism for pushing the second lifting frame 120 up and down, and a second cylinder 122 connected to one end of the second lifting frame 120.

[0107] During operation, the first punching device 2 and the second punching device 5 punch holes in the two unequal sides of the C-shaped channel profile. The distances between the lifting conveyor roller 18 of the first punching device 2 and the lifting conveyor roller 18 of the second punching device 5 and the U-shaped groove of the crossbeam 7 are not equal, resulting in a height difference between the conveyor lines. The first lifting mechanism of the first conveying device 4 drives the second lifting frame 120 to rise and fall. The rising and falling of the second lifting frame 120 makes the height of the fourth roller 121 adjustable. The two height positions of the second lifting frame 120 align the height of the fourth roller 121 with the height of the conveying surface of the flipping device 3 and the roller height of the lifting conveyor roller 18 of the second punching device 5, thus solving the technical problem of the height difference between the conveyor lines hindering conveying. When the piston rod of the second cylinder 122 retracts, the C-shaped channel profile can pass through. When the piston rod of the second cylinder 122 extends, the C-shaped channel profile cannot pass through, thus blocking and positioning the C-shaped channel profile. Based on this, the reference positioning of the C-shaped channel profile when feeding it to the second punching device 5 is achieved. Secondly, when the C-shaped groove profile is being punched in the second punching device 5, the piston rod of the second cylinder 122 extends, which will cause the C-shaped groove profile that has reached the first conveying device 4 to pause its movement and wait for the next process on the first conveying device 4.

[0108] Please refer to Figure 26. In this embodiment, the first lifting mechanism includes a third screw jack 123 and a fourth screw jack 124 whose bodies are connected to the seventh frame 117 and whose screw ends are connected to the second lifting frame 120, and a seventh servo motor 125 that is drively connected to the input shaft of the third screw jack 123 and the input shaft of the fourth screw jack 124.

[0109] The seventh servo motor 125 drives the third screw jack 123 and the fourth screw jack 124 to rotate. The third screw jack 123 and the fourth screw jack 124 drive the second lifting frame 120 to rise and fall, thereby aligning the height of the fourth roller 121 with the height of the conveying surface of the flipping device 3 or with the height of the roller of the lifting conveying roller table 18 of the second punching device 5.

[0110] Please refer to Figure 30. In this embodiment, a feeding device is also provided that is connected to the discharge end of the second punching device 5. The feeding device includes a lifting roller conveyor 126 whose feed end is connected to the discharge end of the second punching device 5, a feeding robot 127, an adjustment and placement frame 128, and a feeding tray 129 located on the side of the lifting roller conveyor 126. The lifting roller conveyor 126 includes an eighth frame, a third lifting frame slidably connected to the eighth frame, a plurality of fifth rollers connected to the third lifting frame, and a second lifting mechanism that pushes the third lifting frame to rise and fall.

[0111] The processed C-slot building templates are stacked with alternating unequal sides for easy storage and transportation. The C-slot building templates output from the second punching device 5 have the same unequal side orientation. During stacking, after the C-slot building templates are conveyed to the lifting roller conveyor 126, the unloading robot 127 directly moves a portion of the C-slot building templates to the unloading tray 129, while the other portion is first moved to the adjusting placement rack 128. The C-slot building templates placed on the adjusting placement rack 128 are flipped by the unloading robot 127 and then moved to the unloading tray 129, thus allowing the two unequal sides of the C-slot building templates to be stacked alternately.

[0112] In this embodiment, the second lifting mechanism includes a fifth screw jack and a sixth screw jack whose bodies are connected to the eighth frame and whose screw ends are connected to the third lifting frame, and an eighth servo motor that is drivenly connected to the input shafts of the fifth screw jack and the sixth screw jack.

[0113] The eighth servo motor drives the fifth and sixth screw jacks to move synchronously, enabling the third lifting frame to rise and fall. The height of the fifth roller can be adjusted to adapt to changes in the roller height of the lifting conveyor roller 18 of the second punching device 5.

[0114] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this application should be included within the protection scope of this application.
