The correction mechanism 6 includes a sliding table 10, a lifting drive device 601 installed on the sliding table 10, and a correction component 602 installed on the lifting drive device 601.

[0044] The sliding table 10 includes a support base 1001, which is fixed to the worktable 1. The support base 1001 has a movable plate 1006 that slides within it. The support base 1001 is hollow, and slide rails 1002 are fixed to its front and rear sides. Sliding plates I 1007 and II 1003, corresponding to the positions of the slide rails 1002, are fixed to the front and rear sides of the bottom of the movable plate 1006, respectively. Sliding plates I 1007 and II 1003 each have slide rail holes 1004 for mounting the slide rails 1002 and move along the slide rails 1002 through the slide rail holes 1004. The support base 1001 has belts on both its left and right ends. Two pulleys 1008 are connected by a belt 1005. The belt 1005 moves in a direction parallel to the slide rail 1002. The belt 1005 is fixed to the sliding plate I 1007. One of the pulleys 1008 is connected to a motor III 11. The motor shaft of the motor III 11 is fixed to the pulley 1008. When the motor III 11 rotates, it drives the pulley 1008 to rotate clockwise / counterclockwise.

The front end of the forming zone 402 and the front end of the correction zone 401 form a positional difference. When the fabric piece moves from the correction zone 401 to the forming zone 402, the front end of the fabric piece naturally droops due to the positional difference between the front end of the forming zone 402 and the front end of the correction zone 401. A light hole 403 is opened on the front side of the correction zone 401. A correction sensor 404 is provided in the correction zone 401.

The correction zone 401 is equipped with a correction sensor 404. The hemming mechanism 12 is equipped with a fabric sensor 121 on one side. The fabric edge sensor 701, the data sensor, motor I 6025, motor II 6026, motor III 11, correction sensor 404 and fabric sensor 121 are respectively connected to and controlled by the PLC controller 2. Cylinder I 6012, cylinder II 501 and air blowing pipe 1242 are respectively connected to the air pump through the air inlet passage 1221. The air pump is connected to and controlled by the PLC controller 2.

[0052] The selvage sensor 701, the correction sensor 404, and the fabric sensor 121 are all infrared sensors.

[0053] The working principle of the automatic fabric edge-turning machine provided by this utility model is as follows:

[0054] Sewing machine 7 is existing technology.

[0055] In use, a fabric piece is taken from the fabric piece pre-placement table 3 and placed into the correction zone 401 of the conveying platform 4. The PLC controller 2 has built-in control programs and control parameters. The correction sensor 404 in the correction zone 401 positions the fabric piece through the light hole 403 of the correction zone 401 and transmits the data to the PLC controller 2. The PLC controller 2 controls the motor III 11 of the correction mechanism 6 to move the correction mechanism 6 to the correction zone 401. Then, the lifting shaft 6011 of the cylinder I 6012 moves downward, thereby driving the correction component 602 to squeeze the fabric piece through the movable rod 603. The motor I 6025 and the motor II 6026 respectively drive the correction wheel 6027 of the correction component 602 to rotate.

[0056] During the correction process, the correction sensor 404 uses infrared positioning to locate the fabric piece through the light hole 403. The fabric piece is then placed directly onto the correction area 401, covering the light hole 403. Subsequently, the PLC controller 2 independently controls motor I 6025 and motor II 6026 to drive the correction wheel 6027 to rotate for correction. Motor I 6025 and motor II 6026 drive the correction wheel 6027 to rotate counterclockwise or counterclockwise until the front edge of the fabric piece corresponds to the position of the light hole 403, thus completing the correction. The correction area 401 has a square structure, so after the correction is completed, the front edge of the fabric piece is parallel to the long side of the correction area 401.

[0057] After the correction is completed, motors I 6025 and II 6026 drive the correction wheel 6027 to rotate clockwise synchronously, causing the fabric to move backward, resulting in the front edge of the fabric moving backward by 40mm. Then, the correction wheel 6027 presses the fabric and moves it horizontally to the forming area 402. Due to the positional difference between the front edge of the forming area 402 and the front edge of the correction area 401, the front edge of the fabric naturally droops. Simultaneously, the fabric sensor 121 of the flanging mechanism 12 detects the fabric drooping in the forming area 402 and uses the first... Air is blown through air passage 122 to keep the front side of the fabric piece in an inward folded state. After the fabric edge sensor 701 of the sewing machine 7 senses the edge of the fabric piece, it sews the fabric piece. The PLC controller 2 transmits a signal to the data sensor of the cutter assembly 5, thereby controlling the cylinder II 501 of the cutter assembly 5 to work and drive the cutter 502 to move downward, so as to cut the sewing line between the front sewn fabric piece and the unsewn fabric piece, so as to facilitate the cutting of the front sewn fabric piece.
