[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Example 1: A cutting device for producing architectural decorative curtain walls, such as Figures 1 to 8 As shown, it includes a base 1, a conveying part for processing the curtain wall body 2, and a clamping part, wherein the clamping part includes: Guide plate 13: It is fixed to the top outer wall of the base 1, and a slide rod 14 is movably connected to the outer wall of the guide plate 13, and a limit plate 15 is fixed to one end of the slide rod 14 by screws. Upright plate 3: It is fixed to the other end of the slide rod 14 by screws, and a rack 4 is fixed to one side of the outer wall of the upright plate 3 by screws; Vertical plate 20: It is fixed to the top outer wall of the base 1 by screws. The inner wall of the through hole opened on the surface of the vertical plate 20 is rotatably connected to the rotating shaft 9. The outer wall of the rotating shaft 9 is connected by a key to a gear 23 that meshes with the rack 4. Electric telescopic rod 21: Two electric telescopic rods 21 are respectively fixed to the upper and lower surfaces of the upright plate 3 by screws, and the output end of the electric telescopic rod 21 is fixed with a clamping plate 22 by a pin; Protective plate 11: It is fixed to the top outer wall of the base 1, and a drive motor 10 is fixed to one side of the outer wall of the protective plate 11. The output end of the drive motor 10 and the end of the rotating shaft 9 are both fixed with pulleys 5 by pins, and the two pulleys 5 are driven by a synchronous belt 34. The curtain wall body 2, which needs to be cut, can be placed by a conveyor. When the curtain wall body 2 needs to be cut into multiple sections, and a second cut is required after the first cut, the drive motor 10 drives the gear 23 to rotate via the transmission action of the pulley 5 and the synchronous belt 34. During the rotation of the gear 23, the rack 4 moves linearly. The guide plate 13 and the slide rod 14 guide the movement path of the rack 4. Before the rack 4 moves, the two sets of electric telescopic rods 21 drive the corresponding clamping plates 22 to move in sequence, so that the two clamping plates 22... The relative motion clamps and fixes the curtain wall body 2. During the lateral movement of the rack 4, the clamped curtain wall body 2 is moved laterally for transmission. When the curtain wall body 2 has moved a certain distance, the drive 21 drives the 22 to move in the opposite direction and no longer clamps the curtain wall body 2. At this time, the drive motor 10 drives the gear 23 to rotate in the opposite direction through the pulley 5 and the synchronous belt 34, so that the electric telescopic rod 21 and the clamping plate 22 are reset. This makes it easier for the electric telescopic rod 21 and the clamping plate 22 to clamp the curtain wall body 2 again after the curtain wall body 2 has been cut. This allows the curtain wall body 2 to be continuously transported and cut. To ensure that the conveying distance of the curtain wall body is exactly the same each time, a rotary encoder can be installed on the drive motor 10 to monitor and provide feedback on the number of rotations or angle of the motor in real time. By setting a fixed number of pulses through the control system, the rotation angle of the gear 23 can be precisely controlled, driving the rack 4 and the clamped curtain wall body 2 to move for a fixed stroke, thus ensuring the consistency of the conveying distance each time.

[0028] A support frame 8 is fixed to the top outer wall of the base 1. A lifting column 31 is movably connected to the through hole on the surface of the support frame 8. An eccentric disk 6 is fixed to one end of the rotating shaft 9. The same swing arm 32 is movably connected between the top of the lifting column 31 and the outer wall of one side of the eccentric disk 6. A disk seat 29 is welded to the bottom of the lifting column 31. A slide rail 7 is fixed to the top outer wall of the disk seat 29. The same lead screw 30 is movably connected to the inner walls of both sides of the slide rail 7. A second drive motor 12 is fixed to one side outer wall of the slide rail 7. The output end of the second drive motor 12 and one end of the lead screw 30 are connected by a coupling. A slider 25 is movably connected to the inner wall of the slide rail 7. A connecting seat 24 is welded to the top outer wall of the slider 25. A cutting motor 33 is fixed to one side inner wall of the connecting seat 24. A cutting saw blade 19 is fixed to the output end of the cutting motor 33. When the curtain wall body 2 moves to the cutting point, the connecting shaft 9 enables the drive motor 10 to drive the eccentric disk 6 to rotate synchronously. During the rotation of the eccentric disk 6, the swing arm 32 can convert the circular motion of the eccentric disk 6 into the vertical motion of the lifting column 31. When the lifting column 31 moves down, the cutting motor 33 moves down synchronously. The cutting motor 33 drives the cutting saw blade 19 to rotate and cut the curtain wall body 2. The drive motor 12 drives the lead screw 30 to rotate. During the rotation of the lead screw 30, the slider 25 slides along the slide rail 7. The cutting saw blade 19 can cut the curtain wall body 2 while sliding along the curtain wall body 2.

[0029] A T-shaped rod 28 is movably connected to the through hole on the surface of the disc base 29, and the same spring 26 is fixed between the inner top wall of the T-shaped rod 28 and the outer top wall of the disc base 29 by a snap-fit ​​method. A pressure plate 27 is welded to the outer bottom wall of the T-shaped rod 28. By setting a pressure plate 27 so that it contacts the curtain wall body 2 before the cutting saw blade 19 during the downward movement, the pressure plate 27 acts as a pressure limiter on the curtain wall body 2, thereby ensuring the stability of the curtain wall body 2 during cutting. By setting a spring 26 so that after the pressure plate 27 contacts the surface of the curtain wall body 2, the cutting saw blade 19 can continue to move downward to cut the curtain wall body 2, ensuring that when the thickness of the curtain wall body 2 is large, the cutting saw blade 19 can completely cut off the curtain wall body 2.

[0030] The conveying unit includes a second spring 16, a guide rod 17, and an L-shaped plate 18. The L-shaped plate 18 is fixed to the top outer wall of the base 1. The guide rod 17 is movably connected to the inner wall of the through hole opened at the top of the L-shaped plate 18. The two ends of the second spring 16 are respectively fixed to the top inner wall of the L-shaped plate 18 and the bottom inner wall of the guide rod 17 by snap-fit. A U-shaped frame 36 is fixed to the top outer wall of the guide rod 17. A conveyor roller 35 is movably connected between the inner walls on both sides of the U-shaped frame 36. The outer walls of multiple sets of conveyor rollers 35 are connected to the same conveyor belt 37. The outer walls of the conveyor rollers 35 located at both ends of the U-shaped frame 36 are all fixed with drive wheels by pins. The two drive wheels are driven by a drive belt. The curtain wall body 2 can be placed by the conveyor belt 37. After the clamping part clamps and fixes the curtain wall body 2, the curtain wall body 2 slides along the surface of the conveyor belt 37 during the lateral movement of the clamping part. During this process, the conveyor roller 35 rotates under the transmission of the conveyor belt 37. The spring 16 can buffer and protect the curtain wall body 2. At the same time, it can also ensure that the curtain wall body 2 and the upper surface of the conveyor belt 37 remain in contact after the clamping part clamps and fixes the curtain wall body 2 according to the different thicknesses of the curtain wall body 2.

[0031] In this embodiment, the operator first places the curtain wall body 2 on the conveyor belt 37. After starting the equipment, the drive motor 10 drives the gear 23 to rotate through the pulley 5 and the synchronous belt 34, thereby engaging the rack 4 to drive the curtain wall body 2, which is clamped by the electric telescopic rod 21 and the clamping plate 22, to be fed laterally to the cutting point. The rotating shaft 9 drives the eccentric disk 6 to rotate, and pushes the lifting column 31 down through the swing arm 32, so that the pressure plate 27 first presses the curtain wall body 2. Then the cutting saw blade 19 driven by the cutting motor 33 falls to complete the cutting. At the same time, the drive motor 22 can drive the lead screw 30 to make the slider 25 drive the saw blade to move laterally to achieve fixed length or scribing cutting. After the cutting is completed, all components are reset, and the clamping part clamps the curtain wall body 2 again to feed to the next distance. This cycle is repeated to achieve continuous automated production.

[0032] Example 2: A cutting device for producing architectural decorative curtain walls, such as Figures 1 to 8 As shown, in order to ensure the stability of the curtain wall body 2 after it is conveyed to the cutting point, this embodiment makes the following additions based on embodiment 1: a side plate 39 is welded to one side of the outer wall of the U-shaped frame 36, and a T-shaped rod 43 is movably connected to the through hole on the surface of the side plate 39. The same spring 40 is fixed between the inner wall of one side of the T-shaped rod 43 and the outer wall of one side of the side plate 39 by a snap-fit ​​method. A ratchet 42 is fixed to one end of the T-shaped rod 43 by a pin. A ratchet 38 is connected to the outer circumference of one of the conveying rollers 41 by a key. By providing ratchet 42, the ratchet 38 can only rotate in one direction. Therefore, when the clamping part is disengaged from the surface of the curtain wall body 2, the inertia causes displacement between the curtain wall body 2 and the conveyor belt 37, ensuring the relative stability between the curtain wall body 2 and the conveyor belt 37 when the clamping part is reset.

[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
