[0018] like Figures 1-7As shown, specifically in this embodiment, the pressing mechanism 3 includes a pressing horizontal cylinder 302 fixed to the bottom surface of the mounting plate 1, a pressing horizontal connecting plate 306 on the back of the pressing horizontal moving plate 302a on the pressing horizontal cylinder, a pressing vertical connecting plate 307 vertically disposed on one side of the pressing horizontal connecting plate and located outside the pressing horizontal cylinder 302, a pressing vertical cylinder 303 disposed on the vertical surface of the pressing vertical connecting plate, a pressing mounting plate 304 disposed at the upper end of the output shaft of the pressing vertical cylinder, and a pressing sheet 305 disposed on the upper surface of the pressing mounting plate and located on the upper surface of the mounting plate; the mounting plate 1 has a strip-shaped first through hole 101, and the pressing mounting plate 304 extends upward through the first through hole under the drive of the pressing vertical cylinder; the pressing horizontal connecting plate 306 and the pressing vertical connecting plate 307 are connected by integral molding.

The pressing horizontal connecting plate 306, pressing vertical connecting plate 307, pressing vertical cylinder 303, pressing mounting plate 304 and pressing plate 305 move horizontally accordingly. After the pressing vertical cylinder 303 is started, the pressing plate 305 rises under the drive of the pressing mounting plate 304, moves horizontally and reaches the end of the webbing that needs to be pressed.

[0019] like Figures 1-7 As shown, specifically, the pressing mechanism 4 includes a left and right adjusting block 401 vertically fixed to the bottom surface of the mounting plate 1, a pressing horizontal cylinder 402 disposed on one of the vertical surfaces of the left and right adjusting blocks, a pressing vertical connecting plate 406 disposed on the back of the pressing horizontal moving plate 402a on the pressing horizontal cylinder, a pressing vertical cylinder 403 disposed on the back of the pressing vertical connecting plate, a pressing mounting plate 404 disposed on the upper end of the output shaft of the pressing vertical cylinder, and a pressing block 405 disposed on the upper surface of the pressing mounting plate; the mounting plate 1 is provided with a strip-shaped second through hole 102, and the pressing block extends upward through the first through hole under the drive of the pressing mounting plate 404. After the horizontal pressing cylinder 402 is started, it drives the horizontal pressing plate 402a to move horizontally. The vertical pressing connecting plate 406, the vertical pressing cylinder 403, the pressing mounting plate 404, and the pressing block 405 move horizontally accordingly. After the vertical pressing cylinder 403 is started, the pressing block 405 rises under the drive of the pressing mounting plate 404, moves horizontally, and reaches the corner position of the two stacked corners of the triangular workpiece that needs to be pressed. Then, the output shaft of the vertical pressing cylinder 403 retracts, driving the pressing mounting plate 404 and the pressing block 405 to descend. The pressing block 405 then presses the two stacked corners of the triangular workpiece after it is folded.
[0020] like Figures 1-7As shown, specifically, the first folding mechanism 5 includes a first flip-feeding block 501 disposed on the bottom surface of the mounting plate 1, a first folding horizontal cylinder 502 disposed on the first flip-feeding block, a first connecting plate 503 disposed at the end of the output shaft of the first folding horizontal cylinder, a first folding vertical cylinder 504 fixedly connected to the first connecting plate, a first vertical connecting plate 505 disposed at the end of the output shaft of the first folding vertical cylinder, a first folding piece 506 disposed on the upper surface of the first vertical connecting plate, and an optical fiber 507 vertically disposed on the bottom surface of the mounting plate 1 and located on one side of the first flip-feeding block 501; the mounting plate 1 is provided with a third through hole 103, and the first folding piece 506 extends upward through the third through hole under the drive of the first vertical connecting plate 505.
[0021] like Figures 1-7 As shown, specifically, the second folding mechanism 6 and the first folding mechanism 5 are arranged side by side to fold the side of the triangular workpiece together; the second folding mechanism 6 includes a second flipping suction block 601 disposed on the bottom surface of the flipping plate 205, a second folding horizontal cylinder 602 disposed on the second flipping suction block, a second connecting plate 603 disposed at the end of the output shaft of the second folding horizontal cylinder, a second folding vertical cylinder 604 fixedly connected to the second connecting plate, a second vertical connecting plate 605 disposed at the end of the output shaft of the second folding vertical cylinder, and a second folding piece 606 disposed on the upper surface of the second vertical connecting plate; the second folding piece 606 extends upward through the fourth through hole under the drive of the second vertical connecting plate 605.
[0022] The second folding mechanism 6 is arranged side by side with the first folding mechanism 5. In use, the triangular workpiece from the previous process (e.g., loading) is placed on the upper surface of the mounting plate 1 and fixed. Then, the second horizontal folding cylinder 602 is activated, driving the second connecting plate 603 and the second vertical folding cylinder 604 to move horizontally. Upon reaching the folding position, the second vertical folding cylinder 604 is activated, driving the second vertical connecting plate 605 and the second folding piece 606 to move upwards to a predetermined height. The second vertical folding cylinder 604 continues to move horizontally and folds one side of the triangular workpiece. During this process, the action of the first folding mechanism 5 is consistent with that of the second folding mechanism 6. Here, a thin plate is used to press down on the triangular workpiece, while the side to be folded is located outside the bottom surface of the thin plate. When the second folding piece 606 pushes the folding mechanism, the folded side of the triangular workpiece is essentially rolled back relative to the thin plate. After folding, the folded side is located on the upper surface of one side of the thin plate. At this time, the second folding piece 606 and the first folding piece... 506 The folded side is pressed against the upper surface of one side of the thin plate, and then the thin plate is removed. The first vertical connecting plate 505 and the second vertical connecting plate 605 retract simultaneously, pressing the folded side of the triangular piece onto the upper surface of the mounting plate 1. Subsequently, one end of the webbing from the previous process is pressed against the surface of the triangular piece. At this time, half of the triangular piece is located on the upper surface of the flipping plate 205. The motor 201 starts and drives the transmission shaft 204 through the angle reducer 202. The transmission shaft then drives the flipping plate 205. 5. The second folding mechanism 6 flips over, and the triangular workpiece is folded in half. When the motor 201 drives the transmission shaft 204 to rotate 180 degrees through the angle reducer 202, the upper surface of the flipping plate 205 comes into contact with the upper surface of the mounting plate 1, thus completing the folding of the triangular workpiece. The half of the triangular workpiece located on the upper surface of the flipping plate 205 covers the surface of one end of the webbing. Then the pressing mechanism 4 starts, and the pressing block 405 presses the two overlapping corners of the folded triangular workpiece tightly. Figure 8 As shown, the triangular piece 9 is folded in half and then wrapped around one end of the webbing 10.
