Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology, and in particular relates to an automatic fabric correction device. Background Technology

[0002] Fabrics are not only the main material for making clothing, but are also widely used in various home furnishings, such as upholstered sofas and bedding.

[0003] During fabric production, the fabric is transported from one process to another by bypassing multiple roller conveyors on the production equipment. The large number of rollers bypassing this process can easily cause the fabric to deviate from its intended position. When workers notice this deviation, they must first stop the equipment and then manually move the fabric back into place, resulting in low efficiency and wasted time and effort. Summary of the Invention

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide an automatic fabric correction device with novel structure, intelligent correction, high degree of automation, labor-saving and convenient, and strong practicality.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An automatic fabric correction device includes: a frame, a controller, and an infrared sensor. The controller is electrically connected to the infrared sensor. A first guide roller, a second guide roller, and a third guide roller are connected to the frame. The device is characterized by: a correction roller slidably connected left and right on the frame; a drive mechanism on the frame; the controller is electrically connected to the drive mechanism; and the output end of the drive mechanism is screwed to the correction roller. A lifting mechanism on the frame; the controller is electrically connected to the lifting mechanism; and the output end of the lifting mechanism is connected to a pressure roller, which is located above the second guide roller. This correction device features a novel structure, intelligent correction, high automation, labor-saving convenience, and strong practicality.

[0007] Furthermore, the drive mechanism uses a servo motor, which has advantages such as high precision, fast response, and smooth low-speed operation. The output end of the servo motor is connected to a bushing, and one end face of the correcting roller is equipped with a screw, which is screwed to the bushing. The connection is reliable, the transmission is stable, and the practicality is strong.

[0008] Furthermore, a guide rod is provided on the other end face of the correcting roller, and a guide part is provided on the guide rod. A bracket is provided on the frame, and a limiting groove corresponding to the guide part is opened on the bracket. The bracket can restrict the rotation of the guide rod, thereby restricting the rotation of the correcting roller, so that the correcting roller performs reciprocating linear motion, which is stable in orientation and highly reliable.

[0009] Furthermore, both ends of the correcting roller are equipped with retaining rings. During the correction process, the correcting roller can push the fabric through the retaining rings, causing the fabric to move left and right to achieve the purpose of correction. The fabric is blocked by the retaining rings and will not slip off the correcting roller.

[0010] Furthermore, the frame is equipped with vertical grooves corresponding to the shaft ends of the pressure rollers. During the lifting and lowering of the pressure rollers, the frame can limit the back-and-forth swaying of the pressure rollers through the vertical grooves, thereby improving the stability of the lifting and lowering movement of the pressure rollers.

[0011] Furthermore, the lifting mechanism adopts a stroke cylinder, which has the advantages of convenient installation, precise positioning, and reliable and stable use. The output end of the stroke cylinder is equipped with a mounting block, which is fixedly connected to the pressure roller by screws, ensuring reliable fixation, convenient disassembly and assembly, and flexibility.

[0012] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0013] 1. During the conveying process, the offset fabric can be automatically corrected, eliminating the need for manual correction after the equipment is stopped. It is highly automated, labor-saving, convenient, and practical.

[0014] 2. The lifting mechanism can drive the pressure roller to move up and down, thereby changing the distance between the pressure roller and the second guide roller to adapt to different fabrics. It has strong adaptability. The pressure roller, together with the second guide roller, flattens both sides of the fabric, improving the flatness of the fabric and thus improving the quality of the fabric.

Detailed Implementation

[0021] like Figures 1 to 4 As shown, this utility model discloses an automatic fabric correction device, comprising: a frame 1, a controller 2, and an infrared sensor 3. The controller 2 can be a microcontroller. The controller 2 and the infrared sensor 3 are both fixed to the frame 1 by screws. The controller 2 is electrically connected to the infrared sensor 3. A first guide roller 4, a second guide roller 5, and a third guide roller 6 are rotatably connected to the frame 1. The two infrared sensor 3 are located below the second guide roller 5, and the second guide roller 5 is higher than the first guide roller 4 and the second guide roller 5.

[0022] A correcting roller 7 is slidably connected to the frame 1. The correcting roller 7 is higher than the first guide roller 4 and lower than the second guide roller 5. A guide rod 8 is provided on one end face of the correcting roller 7, and a guide part 9 is provided on the guide rod 8. A bracket 10 is provided on the frame 1, and a limiting groove 11 corresponding to the guide part 9 is opened on the bracket 10. The guide part 9 slides left and right along the limiting groove 11. An L-shaped frame 12 is provided on the frame 1, and a drive mechanism is installed on the L-shaped frame 12. The drive mechanism adopts a servo motor 13, which has the advantages of high precision, fast response, and stable low-speed operation. The controller 2 is electrically connected to the servo motor 13. The output end of the servo motor 13 is connected to a coupling 14, and a bushing 15 is provided on the coupling 14. A screw 16 is provided on the other end face of the correcting roller 7. The screw 16 is screwed and fixed to the bushing 15, which is reliable, stable in transmission, and highly practical.

[0023] In operation, the conveyed fabric is sequentially routed around the first guide roller 4, the correcting roller 7, the second guide roller 5, and the third guide roller 6, and then onto the roller conveyor of the next device. After the device starts, it drives the fabric forward. When the fabric shifts to the left, the infrared sensor 3 on the left detects the fabric and sends a signal to the controller 2. The controller 2 controls the servo motor 13 to rotate forward, driving the correcting roller 7 to rotate through the bushing 15. Since the guide rod 8 is restricted by the bracket 10 and cannot rotate, the correcting roller 7 becomes a linear motion, driving the fabric to move to the right until the infrared sensor 3 on the left no longer detects the fabric, and the controller 2 controls the servo motor 13 to stop working. When the fabric shifts to the right, the infrared sensor 3 on the right detects the fabric and sends a signal to the controller 2. The controller 2 controls the servo motor 13 to rotate in reverse, driving the fabric to move to the left until the infrared sensor 3 on the right no longer detects the fabric, and the controller 2 controls the servo motor 13 to stop working.

[0024] Both ends of the correcting roller 7 are equipped with retaining rings 17. During the correction process, the correcting roller can push the fabric through the retaining rings 17, causing the fabric to move left and right to achieve the purpose of correction. The fabric is blocked by the retaining rings 17 and will not slip off the correcting roller 7.

[0025] The frame 1 is equipped with a lifting mechanism, which adopts a stroke cylinder 18. It has the advantages of convenient installation, precise positioning, and reliable and stable use. The controller 2 is electrically connected to the stroke cylinder 18. The output end of the stroke cylinder 18 is equipped with a mounting block 19. The mounting block 19 is connected to the pressure roller 20 by screws. The pressure roller 20 is located above the second guide roller 5.

[0026] The stroke cylinder 18 can drive the pressure roller 20 to move up and down, thereby changing the distance between the pressure roller 20 and the second guide roller 5 to adapt to different fabrics. It has strong adaptability. The pressure roller 20, together with the second guide roller 5, flattens both sides of the fabric, improving the flatness of the fabric and thus improving the quality of the fabric.

[0027] The frame 1 is provided with a vertical through groove 21 corresponding to the shaft end of the pressure roller 20. During the lifting and lowering process of the pressure roller 20, the frame 1 can limit the back-and-forth swaying of the pressure roller 20 through the vertical through groove 21, thereby improving the stability of the lifting and lowering movement of the pressure roller 20.

[0028] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
