[0002] Fabric folding machines belong to textile machinery and are mainly used to fold continuous fabric into rectangular blocks. Existing fabric folding machines generally include a fabric feeding device and a fabric folding device. The fabric feeding device includes a frame with guide rollers driven by a motor. The fabric is conveyed to the fabric folding device via the guide rollers for reciprocating folding and laying.

[0003] Utility model patent CN209383123U discloses a device including a frame, a guide roller on the frame, and a correction mechanism on the frame. The correction mechanism includes a crossbar mounted on the frame, two motors spaced apart on the crossbar, a turntable mounted on the output shaft of the motors, multiple driven wheels mounted on the periphery of the turntables, and a detection component mounted on the crossbar and electrically connected to the motors. The driven wheels abut against the guide rollers. The two turntables rotate in opposite directions, and the rotation plane of the turntables is perpendicular to the fabric conveying path. The rotation plane of the turntables is also perpendicular to the rotation plane of the driven wheels. The detection component is used to detect the edge of the fabric. This utility model, through the arrangement of the detection component, motors, and turntables, enables the fabric to be pulled back to the correct position when it deviates, thus making the folded fabric more neat.

[0004] However, in the above-mentioned device, when the driven wheel contacts the fabric and drags the fabric under the action of the motor, the fabric may fold together and the correction effect may be poor. In severe cases, the fabric may be damaged, which will affect the quality of subsequent fabric stacking. Manual assistance is required for adjustment, resulting in low fabric stacking efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a correction device for a fabric lining machine, which can prevent damage to the fabric during correction and has a good correction effect.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a correction device for a fabric stacking machine, comprising a frame, a guide roller for conveying fabric is provided on the frame, a portal-shaped support frame is slidably connected to the frame in the vertical direction, a pressure roller is rotatably connected to the support frame, the pressure roller is arranged parallel to the guide roller and is located directly above the guide roller, a detection component for monitoring the edge position of the fabric is provided on the support frame, and a correction component is provided on the frame, the correction component comprising a correction roller hinged to the frame and a drive component for controlling the correction roller to make arc-shaped movements in the horizontal direction, the correction roller being located on one side of the guide roller and the correction roller being arranged horizontally.

[0023] A further feature of this invention is that a vertically arranged guide rod is fixedly connected to the top of the support frame. There are two guide rods, which are respectively arranged at both ends of the drive cylinder. The guide rods pass through the frame and are slidably connected to the frame.

[0024] The beneficial effects of this utility model are:

[0025] 1. In this utility model, the fabric is conveyed by the guide roller, and the detection component detects the conveyed fabric.

[0026] 2. In this utility model, the drive disc rotates, and the slide bar on the drive disc moves in the strip groove, thereby driving the drive rod through the strip groove to control the correction roller to swing, thus realizing the correction operation of the fabric.

[0027] 3. In this utility model, the swing amplitude of the correction roller is adjustable. When the fabric is relatively light, the control moving block is brought closer to the center. At this time, the drive disc rotates, the swing amplitude of the drive rod and the correction roller is smaller, and the offset distance of the fabric is reduced, thereby improving the pre-positioning effect of the lighter fabric.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] Example: Please refer to Figure 1-4 A fabric feeding machine's deviation correction device includes a frame 1, on which a guide roller 2 for conveying fabric is mounted. A portal-shaped support frame 3 is slidably connected to the frame 1 in the vertical direction. A pressure roller 4 is rotatably connected to the support frame 3. The pressure roller 4 is parallel to the guide roller 2 and is located directly above the guide roller 2. A detection component 5 for monitoring the edge position of the fabric is mounted on the support frame 3. A deviation correction component 6 is mounted on the frame 1. The deviation correction component 6 includes a deviation correction roller 61 hinged to the frame 1 and a drive component 62 for controlling the deviation correction roller 61 to make arc-shaped movements in the horizontal direction. The deviation correction roller 61 is located on one side of the guide roller 2 and is horizontally positioned. The fabric is conveyed through the guide roller 2. The detection component 5 detects the conveyed fabric. When a deviation of the fabric is detected, the drive component 62 controls the deviation correction roller 61 to swing in an arc shape, thereby realizing the automatic deviation correction operation of the fabric.

[0036] Furthermore, one end of the frame 1 is provided with an arc-shaped slide rail 63, and one end of the correction roller 61 is fixedly connected to a connecting rod 64. The connecting rod 64 is arranged collinearly with the correction roller 61. The end of the connecting rod 64 away from the correction roller 61 is fixedly connected to a vertical limiting pin 65. The limiting pin 65 is embedded in the arc-shaped slide rail 63 and is slidably connected to the arc-shaped slide rail 63. The limiting pin 65 at the end of the connecting rod 64 moves in the arc-shaped slide rail 63, thereby driving the correction roller 61 to swing in an arc along the arc-shaped slide rail 63.

[0037] Furthermore, the drive assembly 62 includes a drive rod 621 fixedly connected to the correction roller 61, a strip groove 622 disposed on the drive rod 621, and a drive disk 623 rotatably connected to the frame 1. The strip groove 622 is disposed along the length direction of the drive rod 621. The drive rod 621 is collinear with the correction roller 61. The drive rod 621 is located at the end of the correction roller 61 away from the connecting rod 64. The end of the drive rod 621 away from the correction roller 61 is hinged to the frame 1. The drive disk 621... The frame 3 is provided with a slide rod 624, which is embedded in the strip groove 622 and is slidably connected to the strip groove 622. The frame 1 is provided with a rotary motor 625 that controls the rotation of the drive disk 623 and thus controls the swing of the drive rod 621 through the strip groove 622. The rotary motor 625 controls the rotation of the drive disk 623. At this time, the slide rod 624 on the drive disk 623 moves in the strip groove 622, thereby driving the drive rod 621 through the strip groove 622 to control the swing of the correction roller 61.

[0038] Furthermore, a groove 67 is formed on the drive disk 623 along the radial direction. A screw 68 is rotatably connected in the groove 67. A moving block 69 is threadedly connected to the screw 68. The moving block 69 is slidably connected to the groove 67. A slide rod 624 is fixedly connected to the moving block 69. A drive motor 66 is fixedly connected to the end of the screw 68. The drive motor 66 is fixedly connected to the drive disk 623. The drive motor 66 controls the rotation of the screw 68, thereby controlling the position of the moving block 69 on the drive disk 623. When the moving block 69 is close to the center, the drive disk 623 rotates, and the swing amplitude of the drive rod 621 and the correction roller 61 is small. When the moving block 69 is located at the edge of the drive disk 623, the drive disk 623 rotates, and the swing amplitude of the drive rod 621 and the correction roller 61 is large.

[0039] Furthermore, a drive cylinder 7 is fixedly connected to the frame 1 in the vertical direction. The output end of the drive cylinder 7 is fixedly connected to the support frame 3. The drive cylinder 7 controls the support frame 3 to lower, so that the pressure roller 4 is close to the guide roller 2, which facilitates the pressing and conveying of fabrics of different thicknesses.

[0040] Furthermore, the detection component 5 includes photoelectric sensors 51 symmetrically arranged at both ends of the guide roller 2. The support frame 3 is equipped with a control component 52 for controlling the horizontal displacement of the photoelectric sensors 51. The control component 52 includes a control rod 521 rotatably connected to the support frame 3. The control rod 521 has threads of the same pitch but opposite directions. A sliding block 522 is threadedly connected to the control rod 521. The photoelectric sensor 51 is fixedly connected to the sliding block 522, and the sliding block 522 is slidably connected to the support frame 3. The control lever 521 is arranged parallel to the guide roller 2. A control motor 523 is fixedly connected to the end of the control lever 521. The control motor 523 is fixedly connected to the support frame 3. The photoelectric sensor 51 can detect whether the fabric is deviated on the guide roller 2, so that the correction roller 61 swings to correct the fabric. When fabrics of different widths are stacked, the control motor 523 controls the control lever 521 to rotate, thereby adjusting the position of the two sliding blocks 522, and thus adjusting the distance between the photoelectric sensor 51, improving the detection accuracy of the fabric.

[0041] Furthermore, the surface of the correction roller 61 is knurled to increase the friction of the correction roller 61.

[0042] Furthermore, a rotating motor is fixedly connected to the end of the guide roller 2, and the rotating motor is fixedly connected to the frame 1.

[0043] Furthermore, a vertically arranged guide rod 8 is fixedly connected to the top of the support frame 3. There are two guide rods 8, which are respectively arranged at both ends of the drive cylinder 7. The guide rod 8 passes through the frame 1 and is slidably connected to the frame 1.

[0044] Working principle of this utility model:

[0045] The fabric is conveyed by the guide roller 2. When fabrics of different widths are stacked, the control motor 523 controls the control rod 521 to rotate, thereby adjusting the position of the two sliding blocks 522 and adjusting the distance between the photoelectric sensors 51. When the fabric is detected to be deviating, the rotary motor 625 controls the drive disk 623 to rotate. At this time, the sliding rod 624 on the drive disk 623 moves in the strip groove 622, thereby driving the drive rod 621 through the strip groove 622 to control the correction roller 61 to swing, realizing the automatic correction operation of the fabric.

[0046] When the fabric is relatively light, the control moving block 69 moves closer to the center. At this time, the drive disk 623 rotates, and the swing amplitude of the drive rod 621 and the correction roller 61 is smaller, reducing the offset distance of the fabric and thus improving the pre-positioning effect of the lighter fabric.
