[0002] Currently, folding long, flexible materials is a crucial process step in many industrial applications for manufacturing various products, such as textiles, packaging materials, and industrial goods. Traditionally, this folding process typically requires manual operation or mechanical devices. However, traditional methods have several drawbacks, including low production efficiency, low folding accuracy, and high operating costs. Traditional devices cannot achieve precise folding, leading to increased errors during the folding process and affecting the quality of the final product. Some existing devices require complex operating procedures or cumbersome adjustment steps, necessitating highly trained operators for correct operation, increasing production and time costs. Due to operational complexity and limitations in folding accuracy, existing devices often cannot meet the demands of high-efficiency production, resulting in low production efficiency and limited capacity. Some existing devices may only be suitable for specific types or sizes of flexible materials, failing to meet the needs of different sizes and materials. These problems lead to a high number of workers, high labor intensity, and long continuous working hours during processing. These issues not only increase costs but also compromise the folding quality of long, flexible materials, resulting in low production efficiency.

[0003] In view of the problems existing in the above-mentioned prior art, it is necessary to study and design a new type of automated multiple folding device for long strip flexible materials under clamping guide rail, so as to overcome the problems existing in the prior art.

The clamping guide system is designed to accommodate a range of flexible material sizes, improving the device's adaptability. The device is equipped with an intelligent automated control unit that monitors the folding process in real time through sensors and feedback mechanisms, and automatically adjusts according to preset parameters. This enables a high degree of automation in the entire folding process, reducing operator intervention. This invention innovatively designs a clamping mechanism, which allows for more precise and flexible folding of flexible materials. The device is designed to accommodate long, flexible materials up to 10 meters long and 2 meters wide, while also possessing flexibility to meet different production needs.

Furthermore, the folding panel frame is equipped with an infrared ranging sensor B, which is used to detect the running distance of the long strip of flexible material.

[0016] Furthermore, the processing steps of the automated multi-folding device for elongated flexible materials under the clamping guide rail are as follows: S1. Based on the size and material of the long strip of flexible material to be folded, adjust the infrared ranging sensor A on the material support frame and the infrared ranging sensor B on the three folding plates according to the number of folding layers through the electrical cabinet to measure the passing distance of the long strip of flexible material; start the switch on the electrical cabinet to fold it. S2. The conveying mechanism transports the long strip of flexible material into the aluminum profile frame. After the infrared ranging sensor A detects that the distance the long strip of flexible material has traveled has reached the clamping length, it transmits the signal to the control system in the electrical cabinet, which instructs the cylinder A of the clamping mechanism to control the two clamping rods to clamp the middle of the long strip of flexible material located at the front end of the conveying mechanism. S3. After clamping the long strip of flexible material, the longitudinal servo motor is activated to control the clamping mechanism to move vertically along the short guide rail to the top of the guide rail mechanism; the transverse servo motor is activated to control the short guide rail to clamp the long strip of flexible material through the clamping mechanism and transport it along the long guide rail to the middle of the aluminum profile frame, completing the first folding and transportation of the long strip of flexible material. S4. The long strip of flexible material, after being folded once, is supported by the support rods on the material support frame and clamped by the clamping rods, and inserted between the folding conveyor mechanism A and the folding conveyor mechanism C of the multi-folding mechanism; servo motor A drives the conveyor belt A to rotate through the active roller A, cooperating with the folding conveyor mechanism C to clamp the double-layer long strip of flexible material and move it backward. Servo motor B on the folding conveyor mechanism B starts forward, conveying the long strip of flexible material backward. After the infrared ranging sensor B on the folding plate in the middle of the second folding conveyor structure detects that the distance traveled by the long strip of flexible material has reached the clamping length, it sends a signal. The control system in the electrical cabinet is instructed to start the servo motor B in reverse, which in turn activates the cylinder B on the folding plate to push the folding plate downwards, pushing the two layers of long strip-shaped flexible material between the folding conveyor mechanism C and the folding conveyor mechanism B. After being clamped and conveyed by the folding conveyor mechanism C and the folding conveyor mechanism D, the long strip-shaped flexible material is folded twice. After the second folding is completed, the folding conveyor mechanism B rotates forward, ready to participate in the next material transfer and folding. When the long strip-shaped flexible material has completely entered the multi-folding mechanism, the guide rail mechanism and the clamping mechanism are reset, and the next clamping and movement is performed. S5. The long strip of flexible material, after being folded twice, moves backward by being clamped by folding conveyor mechanism D and folding conveyor mechanism E. Servo motor F starts in the forward direction, driving the long strip of flexible material to move backward. After infrared ranging sensor B on the folding plate in the middle of the third folding conveyor structure detects that the distance traveled by the long strip of flexible material has reached the clamping length, it transmits a signal to the control system in the electrical cabinet, instructing servo motor F to start in the reverse direction, starting cylinder B on the folding plate to push the folding plate downward, pushing the four layers of long strip of flexible material between folding conveyor mechanism E and folding conveyor mechanism F. Folding conveyor mechanism F works similarly to folding conveyor mechanism B. After the third fold is completed, it rotates normally, ready to participate in the next material transfer and folding. After being clamped and conveyed by folding conveyor mechanism E and folding conveyor mechanism G, the long strip of flexible material is folded three times. S6. The long strip of flexible material, after being folded three times, is clamped and moved downwards by folding conveyor mechanisms E and G, falling into the tray. After the infrared ranging sensor B on the folding plate in the middle of the fourth folding conveyor structure detects that the distance traveled by the long strip of flexible material has reached the clamping length, it transmits a signal to the control system in the electrical cabinet, instructing the cylinder B on the folding plate to push the folding plate to move laterally, pushing the eight layers of long strip of flexible material between folding conveyor mechanisms G and H. After being clamped and conveyed by folding conveyor mechanisms G and H, the long strip of flexible material is folded four times. Finally, the folding conveyor H outputs the folded long strip of flexible material to the next station.

[0043] The processing steps of the automated multi-folding device for long strip flexible materials under clamping guide rails are as follows: S1. Based on the size and material of the long strip of flexible material to be folded, adjust the infrared ranging sensor A52 on the material support frame 5 and the infrared ranging sensor B74 on the three folding plates 7 according to the number of folding layers through the electrical cabinet 8 to measure the passing distance of the long strip of flexible material; start the switch on the electrical cabinet 8 to fold it. S2. The conveying mechanism 2 transports the long strip of flexible material into the aluminum profile frame 1. After the infrared ranging sensor A52 detects that the distance the long strip of flexible material has traveled has reached the clamping length, it transmits the signal to the control system in the electrical cabinet 8, which instructs the cylinder A32 of the clamping mechanism 3 to control the two clamping rods 34 to clamp the middle of the long strip of flexible material located at the front end of the conveying mechanism 2. S3. After clamping the long strip of flexible material, the longitudinal servo motor 409 starts to control the clamping mechanism 3 to move vertically along the short guide rail 402 to the top of the guide rail mechanism 4; the transverse servo motor 408 starts to control the short guide rail 402 to clamp the long strip of flexible material through the clamping mechanism 3 and transport it along the long guide rail 401 to the middle of the aluminum profile frame 1, completing the first folding and transportation of the long strip of flexible material. S4. The long strip of flexible material, after being folded once, is supported by the support rod 53 on the material support frame 5 and clamped by the clamping rod 34. It is then inserted between the folding conveyor mechanism A65 and the folding conveyor mechanism C67 of the multi-folding mechanism 6. The servo motor A654 drives the conveyor belt A653 to rotate through the active roller A651, which works in conjunction with the folding conveyor mechanism C67 to clamp the double-layer long strip of flexible material and move it backward. The servo motor B664 on the folding conveyor mechanism B66 starts forward, conveying the long strip of flexible material backward. The infrared ranging sensor B74 on the folding plate 7 in the middle of the second folding conveyor structure detects that the distance traveled by the long strip of flexible material has reached the clamping length. The signal is transmitted to the control system in the electrical cabinet 8, which instructs the servo motor B664 to start in reverse, activating the cylinder B73 on the folding plate 7 to push the folding plate 72 downward, pushing the two layers of long strip flexible material between the folding conveyor mechanism C67 and the folding conveyor mechanism B66. After being clamped and conveyed by the folding conveyor mechanism C67 and the folding conveyor mechanism D68, the long strip flexible material is folded twice. After the second folding is completed, the folding conveyor mechanism B66 rotates forward, ready to participate in the next material transfer and folding. When the long strip flexible material has completely entered the multi-folding mechanism 6, the guide rail mechanism 4 and the clamping mechanism 3 are reset, and the next clamping and movement is performed. S5. The long strip of flexible material, after being folded twice, is clamped and moved backward by the folding conveyor mechanism D68 and the folding conveyor mechanism E69. The servo motor F6104 starts in the forward direction, driving the long strip of flexible material to move backward. The infrared ranging sensor B74 on the folding plate 7 in the middle of the third folding conveyor structure detects that the distance traveled by the long strip of flexible material has reached the clamping length. It transmits the signal to the control system in the electrical cabinet 8, instructing the servo motor F6104 to start in the reverse direction. The cylinder B73 on the folding plate 7 is activated to push the folding plate 72 downward, pushing the four layers of long strip of flexible material between the folding conveyor mechanism E69 and the folding conveyor mechanism F610. The folding conveyor mechanism F610 works similarly to the folding conveyor mechanism B66. After the third fold is completed, it rotates normally, ready to participate in the next material transfer and folding. After being clamped and conveyed by the folding conveyor mechanism E69 and the folding conveyor mechanism G611, the long strip of flexible material is folded three times. S6. The long strip of flexible material, after being folded three times, is clamped and moved downwards by the folding conveyor mechanism E69 and the folding conveyor mechanism G611 into the tray 63. After the infrared ranging sensor B74 on the folding plate 7 in the middle of the fourth folding conveyor structure detects that the distance traveled by the long strip of flexible material has reached the clamping length, it transmits a signal to the control system in the electrical cabinet 8. The control system then activates the cylinder B73 on the folding plate 7 to push the folding plate 72 laterally, pushing the eight layers of long strip of flexible material between the folding conveyor mechanism G611 and the folding conveyor mechanism H612. After being clamped and conveyed by the folding conveyor mechanism G611 and the folding conveyor mechanism H612, the long strip of flexible material is folded four times. Finally, the folding conveyor mechanism H612 outputs the folded long strip of flexible material to the next station.

The roller shaft of the transmission roller H (6121) is equipped with a single-layer gear H (6124) that meshes with one layer of a double-layer gear F (6114). The driving roller H (6122) is connected to a servo motor H (613) fixed on the multi-folding frame (61). The servo motor H (613) drives the drive roller H (6122) to rotate counterclockwise, which in turn drives the conveyor belt H to move counterclockwise. The transmission roller H (6121), which rotates counterclockwise together, drives the double-layer gear F (6114) to rotate clockwise, which in turn drives the conveyor belt G to move clockwise. The double-layer gear F (6114) then drives the single-layer gear EB (696) and the single-layer gear EA (695) to rotate counterclockwise, which in turn drives the conveyor belt E (694) to move counterclockwise. The single-layer gear EA (695) drives the double-layer gear D (684) to rotate clockwise, which in turn drives the conveyor belt D (683) to move clockwise. The double-layer gear D (684) drives the single-layer gear C (674) to rotate counterclockwise, which in turn drives the conveyor belt C (673) to move counterclockwise.

The folding plate frame (71) is equipped with an infrared ranging sensor B (74) for detecting the running distance of the long strip flexible material.

8. The automated multiple folding device for elongated flexible materials under a clamping guide rail according to any one of claims 1-7, characterized in that: The processing steps of the automated multi-folding device for the long strip flexible material under the clamping guide rail are as follows: S1. According to the size and material of the long strip of flexible material to be folded, adjust the infrared distance sensor A (52) on the material support frame (5) and the infrared distance sensor B (74) on the three folding plates (7) through the electrical cabinet (8) to measure the passing distance of the long strip of flexible material according to the number of folding layers; start the switch on the electrical cabinet (8) to fold it. S2, the conveying mechanism (2) transports the long strip of flexible material into the aluminum profile frame (1). After the infrared ranging sensor A (52) detects that the distance the long strip of flexible material has traveled has reached the clamping length, it transmits the signal to the control system in the electrical cabinet (8) and instructs the cylinder A (32) of the clamping mechanism (3) to control the two clamping rods (34) to clamp the middle of the long strip of flexible material located at the front end of the conveying mechanism (2). S3. After clamping the long strip of flexible material, the longitudinal servo motor (409) is activated to control the clamping mechanism (3) to move vertically along the short guide rail (402) above the guide rail mechanism (4); the transverse servo motor (408) is activated to control the short guide rail (402) to clamp the long strip of flexible material through the clamping mechanism (3) and transport it along the long guide rail (401) to the middle of the aluminum profile frame (1), thus completing the first folding and transportation of the long strip of flexible material; S4. The long strip of flexible material, after being folded once, is supported by the support rod (53) on the material support frame (5) and clamped by the clamping rod (34), and inserted between the folding conveyor mechanism A (65) and the folding conveyor mechanism C (67) of the multi-folding mechanism (6); the servo motor A (654) drives the conveyor belt A (653) to rotate through the active roller A (651) to cooperate with the folding conveyor mechanism C (67) to clamp the double-layer long strip of flexible material and move it backward. The servo motor B (664) on the folding conveyor mechanism B (66) starts in the forward direction and transports the long strip of flexible material backward. The infrared distance sensor B (74) on the folding plate (7) in the middle of the second folding conveyor structure detects that the distance traveled by the long strip of flexible material has reached the clamping length. Then, the signal is transmitted to the control system in the electrical cabinet (8), which instructs the servo motor B (664) to start in reverse, and starts the cylinder B (73) on the folding plate (7) to push the folding plate (72) downward, pushing the two layers of long strip flexible material between the folding conveyor C (67) and the folding conveyor B (66). After being clamped and conveyed by the folding conveyor C (67) and the folding conveyor D (68), the long strip flexible material is folded twice. After the second folding is completed, the folding conveyor B (66) rotates forward, ready to participate in the next material transfer and folding. When the long strip flexible material is completely entered into the multi-folding mechanism (6), the guide rail mechanism (4) and the clamping mechanism (3) are reset, and the next clamping and movement is performed. S5. The long strip of flexible material, after being folded twice, moves backward by being clamped by the folding conveyor mechanism D (68) and the folding conveyor mechanism E (69). The servo motor F (6104) starts forward, driving the long strip of flexible material to move backward. After the infrared ranging sensor B (74) on the folding plate (7) in the middle of the third folding conveyor structure detects that the distance traveled by the long strip of flexible material has reached the clamping length, it transmits the signal to the control system in the electrical cabinet (8), instructing the servo motor F (6104) to start in reverse, starting the... The cylinder B (73) on the folding plate (7) pushes the folding plate (72) downward, pushing the four layers of long strip flexible material between the folding conveyor E (69) and the folding conveyor F (610). The folding conveyor F (610) works the same as the folding conveyor B (66). After the third fold is completed, it rotates normally and is ready to participate in the next material transfer and folding. After being clamped and conveyed by the folding conveyor E (69) and the folding conveyor G (611), the long strip flexible material is folded three times. S6. The long strip of flexible material, after being folded three times, is clamped by the folding conveyor mechanism E (69) and the folding conveyor mechanism G (611) and moves downward into the tray (63). The infrared ranging sensor B (74) on the folding plate (7) in the middle of the fourth folding conveyor structure detects that the distance the long strip of flexible material has traveled has reached the clamping length. It then transmits the signal to the control system in the electrical cabinet (8) and instructs the cylinder B (73) on the folding plate (7) to push the folding plate (72) to move laterally. The eight layers of long strip of flexible material are pushed between the folding conveyor mechanism G (611) and the folding conveyor mechanism H (612). After being clamped and conveyed by the folding conveyor mechanism G (611) and the folding conveyor mechanism H (612), the long strip of flexible material is folded four times. Finally, the folded long strip of flexible material is output to the next station by the folding conveyor mechanism H (612).
