[0002] During the production of cuffs, because the cuffs have an opening, a hemming process is required. That is, the opening of the cuff is first folded over to form a hem at the edge of the cuff, and then the hem is sewn on.

[0003] The existing patent announcement number CN215976345U discloses an automatic hemming sewing device, including a sewing machine and a sewing table. The device is characterized by further including a fabric hemming mechanism located on the side of the sewing table where the fabric is fed in, and a correction roller for correcting the fabric deviation on the fabric hemming mechanism. The fabric hemming mechanism includes a translation drive mechanism, a movable plate, and a hemming auxiliary plate matched with the movable plate. The movable plate is fixed to the translation part of the translation drive mechanism to drive the movable plate to translate beside the hemming auxiliary plate. The correction roller includes a movable correction element and a correction drive device for driving the correction element. This patent results in high consistency of hemming width across different parts of the hemmed area, but the operation of the correction mechanism is not smooth, reducing work efficiency. Therefore, it is necessary to provide a fabric correction mechanism to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to design a fabric correction mechanism that is smooth to operate and has high working efficiency in order to overcome the shortcomings of the above-mentioned technologies.

[0005] To solve the above problems, the present invention provides a fabric correction mechanism, which includes a correction platform, wherein at least two correction detection positions are provided on the correction platform, and the at least two correction detection positions are arranged in a straight line along the length direction of the correction platform.

[0006] A correction assembly is provided above the correction platform. The correction assembly includes a mounting frame, motor I and motor II. Motor I and motor II are arranged in a straight line along the length of the correction platform, and correction wheels are installed on the rotating shafts of motor I and motor II. Motor I and motor II drive the correction wheels to rotate, thereby moving the fabric piece back and forth to correct the deviation of the fabric piece.

[0007] The lifting drive device is located next to the correction platform. The mounting bracket is installed on the lifting part of the lifting drive device to control the lifting of the correction component and realize the squeezing or loosening action on the fabric.

[0008] As a further solution of this utility model, each of the aforementioned correction detection positions includes a correction hole disposed on the correction platform, such that the correction holes are arranged in a straight line along the length direction of the correction platform, and a correction sensor is disposed at the corresponding location of each correction hole.

[0009] As a further solution of this utility model, each of the correction holes is located on the front side of the correction platform, and there is a distance between the center of each correction hole and the front side of the correction platform, which is ≥40mm or ≤40mm. As a further solution of this utility model, the lifting drive device includes cylinder I, and the movable rod is mounted on the lifting shaft of cylinder I.

[0010] As a further solution of this utility model, a fixing plate is fixed to one end of the movable rod, and the fixing plate is fixedly connected to the mounting frame through a fixing column. The top end of the support column of the correction mechanism is hinged to the front end of the support column. The cylinder I drives the lifting shaft to move up and down, thereby driving the correction wheel to squeeze or relax the cloth. An elastic element is provided on the outside of the fixing column.

[0011] As a further solution of this utility model, the elastic element is a spring sleeved outside the fixed column, with its upper and lower ends respectively abutting against the fixed plate and the mounting bracket.

[0012] As a further solution of this utility model, the correction wheel is covered with rubber, and the rubber outside the correction wheel increases the friction on the cloth, making the correction more efficient.

[0014] As a further solution of this utility model, a forming platform is provided on one side of the correction platform and arranged side by side with the correction platform. The forming platform and the side of the correction platform near the correction component form a positional difference. When the fabric moves from the correction platform to the forming platform, the fabric naturally droops due to the positional difference between the forming platform and the correction platform, which facilitates the turning over of the fabric.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0026] like Figures 1 to 5 As shown, the fabric correction mechanism described in this embodiment includes a correction platform 1, on which at least two correction detection positions are provided, and the at least two correction detection positions are arranged in a straight line along the length direction of the correction platform 1.

[0027] A correction assembly 2 is provided above the correction platform 1. The correction assembly 2 includes a mounting frame 204, a motor I 205 and a motor II 206. The motor I 205 and the motor II 206 are arranged in a straight line along the length of the correction platform 1. Correction wheels 207 are installed on the rotating shafts of the motor I 205 and the motor II 206. The motor I 205 and the motor II 206 drive the correction wheels 207 to rotate, thereby moving the fabric piece back and forth to correct the deviation of the fabric piece.

[0028] The lifting drive device 6 is located next to the correction platform 1. The mounting bracket 204 is installed on the lifting part of the lifting drive device 6 to control the lifting of the correction component 2, thereby realizing the squeezing or loosening action on the fabric.

[0029] Each of the aforementioned correction detection positions includes a correction hole 102 disposed on the correction platform 1, such that each correction hole 102 is arranged in a straight line along the length direction of the correction platform 1, and a correction sensor 103 is disposed at the corresponding location of each correction hole 102.

[0030] Each of the aforementioned correction holes 102 is located on the front side of the correction platform 1, and there is a distance between the center of each correction hole 102 and the front side of the correction platform 1, which is ≥40mm or ≤40mm.

[0031] The lifting drive device 6 includes cylinder I 602, and the movable rod 7 is mounted on the lifting shaft 601 of cylinder I 602.

[0032] One end of the movable rod 7 is fixed with a fixing plate 201. The fixing plate 201 is fixedly connected to the mounting frame 204 through a fixing column 203. The top end of the support column 8 of the correction mechanism is hinged to the front end of the support column 8. The cylinder I 602 drives the lifting shaft 601 to move up and down, thereby driving the correction wheel 207 to squeeze or relax the cloth. The fixing column 203 is provided with an elastic element.

[0033] The elastic element is a spring 202, which is sleeved on the outside of the fixed post 203, with its upper and lower ends abutting against the fixed plate 201 and the mounting bracket 204, respectively.

[0034] The correction wheel 207 is covered with a rubber sleeve, which increases the friction on the cloth, making the correction more efficient.

[0035] The lifting drive device 6 has a sliding platform 3 at its bottom, which is arranged along the length of the correction platform 1. The sliding platform 3 is supported by a base 301, and a movable plate 306 is provided inside the base 301 to slide and engage with it. Slide rails 302 are fixed on both the front and rear sides of the bottom of the base. Sliding plates I 307 and II 303, corresponding to the positions of the slide rails 302, are fixed on the front and rear sides of the bottom of the movable plate 306, respectively. Sliding plates I 307 and II 303 each have slide rail holes 304 for assembling the slide rails 302 and move along the slide rails 302 through the slide rail holes 304. The base 301 is driven by a conveying assembly 4 to slide and engage with the movable plate 306. The conveying assembly includes two pulleys 402, which are located at the left and right ends of the support base 301. The two pulleys 402 are connected by a belt 401, which moves in a direction parallel to the slide rail 302. The belt 401 is fixed to the sliding plate I 307. One of the pulleys 402 is connected to a motor III 305, whose motor shaft is fixed to the pulley 402. When the motor III 305 rotates, it drives the pulley 402 to rotate clockwise / counterclockwise. The belt 401 drives the correction mechanism to move to the right / left through the sliding plate I 307, thereby realizing the function of the correction mechanism in conveying the fabric. A support column 8 is fixed to the top of the moving plate 306, and the top of the support column 8 is rotatably connected to the movable rod 7.

[0036] The correction platform 1 has a forming platform 5 arranged side by side with the correction platform 1. The forming platform 5 and the side of the correction platform 1 that is close to the correction component 2 form a positional difference. When the fabric moves from the correction platform 1 to the forming platform 5, the fabric naturally hangs down due to the positional difference between the forming platform 5 and the correction platform 1, which facilitates the turning over of the fabric.

[0037] The correction sensor 103 is an infrared sensor.

[0038] The working principle of the fabric correction mechanism provided by this utility model is as follows:

[0039] In use, the fabric piece is placed on the correction platform 1. The correction sensor 103 of the correction platform 1 positions the fabric piece through the correction hole 102 of the correction zone and transmits the data to the PLC controller. The PLC controller controls motor III 305 611 to drive the correction component 2 to move to the correction platform 1. Then, the lifting shaft 601 of cylinder I 602 moves downward and drives the correction component 2 to squeeze the fabric piece through the movable rod 7. Motor I 205 and motor II 206 drive the correction wheel 207 of the correction component 2 to rotate respectively.

[0040] During the correction process, the correction sensor 103 uses infrared positioning to locate the fabric piece through the correction hole 102. The fabric piece is then placed directly on the correction platform 1, covering the correction hole 102. Subsequently, the PLC controller independently controls motor I 205 and motor II 206 to drive the correction wheel 207 to rotate for correction. Motor I 205 and motor II 206 drive the correction wheel 207 to rotate clockwise or counterclockwise until the front edge of the fabric piece corresponds to the position of the correction hole 102, thus completing the correction. The correction platform 1 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.

[0041] After the correction is completed, motor I 205 and motor II 206 drive the correction wheel 207 to rotate clockwise in sync, causing the fabric to move backward, so that the front edge of the fabric moves backward by 40mm. Then, the correction wheel 207 presses the fabric and moves the fabric to the forming area 402. The front edge of the fabric hangs down naturally due to the positional difference between the front edge of the forming platform 5 and the front edge of the correction platform 1, which makes it easy to turn the fabric edge.

[0042] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
