Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of fabric processing technology, and more specifically, to a fabric conveying correction device. Background Technology

[0002] During fabric processing, to prevent pattern misalignment due to offset during dyeing and printing, a fabric conveying and correction device is required. This device is used in industrial automation to ensure stable alignment of flexible materials such as fabrics, films, and paper during transport. It detects and adjusts material positional deviations in real time, preventing problems such as wrinkles, tears, and printing misalignment caused by misalignment. It is widely used in the textile, printing, packaging, and non-woven fabric industries.

[0003] Traditional fabric conveying correction devices have the following shortcomings: When conveying ultra-wide fabrics, traditional devices first pair an infrared or laser emitter with a receiver. When the fabric edge blocks the light, the receiver detects the change in light intensity. Then, the entire conveying unit is moved laterally. After the actuator moves, the sensor continuously monitors the new position, forming a closed loop of "detection → adjustment → re-detection" until the error approaches zero. However, the overall frame translation requires moving the entire conveying unit (including rollers, supports, drive components, etc.), resulting in a total mechanical weight of hundreds of kilograms to several tons. Driving such a heavy component requires a high-power motor or hydraulic system, significantly increasing energy consumption. It also requires high-power drive, has high inertia, and necessitates predictive control algorithms. Therefore, improvements are needed. Utility Model Content

[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0026] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0028] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1 to 6 As shown, a fabric conveying correction device according to an embodiment of the present disclosure is illustrated, including a platform 1, a correction mechanism 6 disposed above the platform 1, the correction mechanism 6 including a U-shaped frame 604 located above the platform 1, a roller 610 rotatably mounted on the inner side of the U-shaped frame 604, a first top plate 605 fixedly mounted above the U-shaped frame 604, a disc 606 fixedly mounted above the first top plate 605, a second top plate 607 rotatably mounted above the disc 606, a servo motor 608 fixedly mounted above the second top plate 607, a rotating shaft 609 fixedly mounted below the servo motor 608, the rotating shaft 609 being fixedly connected above the disc 606, and side plates 5 fixedly mounted on the upper sides of both sides of the platform 1, with arc-shaped grooves 615 corresponding to the U-shaped frame 604 on both sides of the side plates 5.

[0032] In some examples, during use, the fabric is first passed sequentially through roller 613 to the outside of the collecting device 7, allowing the fabric to be processed by the processing device 2. When the photoelectric sensor 614 detects a deviation in the fabric, it releases an electrical signal to the PLC. The PLC receives the signal from the photoelectric sensor 614 and transmits it to the controller, which in turn drives the hydraulic cylinder 602 to operate. The hydraulic cylinder 602 drives the telescopic rod 603 to operate, which in turn drives the U-shaped frame 604 to move upward. This causes roller 610 to move upward and lift the fabric. At this time, the servo motor 608 runs, driving the rotating shaft 609 to rotate. The rotating shaft 609 drives the disc 606 to rotate, which in turn drives the U-shaped frame 604 to rotate, causing roller 610 to deflect, thereby calibrating and correcting the fabric.

[0033] The fabric is lifted by a U-shaped frame 604, which then drives roller 610 to deflect, thereby correcting the fabric's deviation. Compared with traditional fabric conveying correction devices, this fabric conveying correction device lifts the fabric using roller 610, creating a linkage between the fabric and roller 610. When roller 610 deflects, the fabric moves along with it, thus correcting the deviation. This eliminates the need to drive the entire conveying unit to move laterally for correction. By using roller 610 to lift the fabric and make it an independent conveying unit, energy consumption is saved. It is also suitable for fabrics of different sizes and is easy to use.

[0034] like Figures 1-6 As shown, a correction device for fabric conveying is illustrated in another embodiment of the present disclosure. A placement mechanism 3 is provided at the front end of the platform 1. The placement mechanism 3 includes a fabric roller 32. Positioning mechanisms 4 are provided on the outer sides of both ends of the fabric roller 32. The positioning mechanism 4 includes a bottom ring block 41 that is movably sleeved on the outer side of the fabric roller 32. A threaded groove ring 42 is fixedly installed on the outer side of the bottom ring block 41. A threaded ring 45 is threadedly installed on the inner side of the threaded groove ring 42. A retaining ring 47 is fixedly installed on the inner side of the threaded ring 45. A connecting block 43 is fixedly installed on the inner side of the bottom ring block 41. An elastic ring 44 is fixedly installed on the inner side of the connecting block 43.

[0035] In some examples, after the fabric is wrapped around the surface of the fabric roller 32, the fabric roller 32 is slid so that the bottom ring block 41 slides on the outside of the fabric roller 32, so that the bottom ring block 41 contacts the fabric. Then, the knob 46 is rotated so that the knob 46 rotates inside the threaded ring 42, thereby driving the threaded ring 45 to move inward, causing the retaining ring 47 to move inward and squeeze the outer wall of the elastic ring 44. The elastic ring 44 is compressed inward by the squeezing force of the retaining ring 47, so that the elastic ring 44 clamps and fixes the outer wall of the fabric roller 32, thereby positioning the position of the fabric through the positioning mechanism 4.

[0036] By sliding the fabric roller 32 to bring the bottom ring block 41 into contact with the fabric, and then rotating the knob 46 to clamp and fix the elastic ring 44 to the outer wall of the fabric roller 32, compared with the traditional correction device for fabric conveying, this correction device for fabric conveying positions the fabric outside the fabric roller 32 through the bottom ring block 41, preventing the fabric from moving around the fabric roller 32 during the conveying process, thus preventing the fabric from deviating during the conveying process.

[0037] like Figures 1-6 As shown, it illustrates a fabric conveying correction device in another embodiment of the present disclosure. The platform 1 has a slot 601 inside, a hydraulic cylinder 602 is fixedly installed inside the slot 601, a telescopic rod 603 is fixedly installed above the hydraulic cylinder 602, and a U-shaped frame 604 is rotatably installed above the telescopic rod 603.

[0038] In some examples, the hydraulic cylinder 602 is activated, causing the telescopic rod 603 to move upward, thereby lifting the U-shaped frame 604 and bringing the roller 610 into contact with the fabric.

[0039] like Figures 1-6 As shown, a fabric conveying correction device is illustrated in another embodiment of the present disclosure. A synchronous motor 611 is fixedly mounted on the outer side of the U-shaped frame 604, and the output end of the synchronous motor 611 is fixedly connected to the front end of the roller 610.

[0040] In some examples, the synchronous motor 611 is started, which drives the roller 610 to rotate, thereby transferring the fabric.

[0041] like Figures 1-6 As shown, a fabric conveying correction device is provided in another embodiment of the present disclosure. A synchronous motor 612 is fixedly installed on the outer side of the side plate 5, and a roller 613 is rotatably installed on the inner side of the side plate 5. The output end of the synchronous motor 612 is fixedly connected to the front end of the roller 613.

[0042] In some examples, synchronous motor 612 is started, which drives roller 613 to rotate, so that roller 613 straightens the fabric.

[0043] like Figures 1-6 As shown, a fabric conveying correction device is illustrated in another embodiment of this disclosure. A processing device 2 is fixedly installed on the outer right side of the platform 1, and a collecting device 7 is fixedly installed on the right side of the platform 1.

[0044] In some examples, the fabric transported to the processing device 2 is processed by the processing device 2, and the processed fabric is wrapped around the outside of the collection device 7.

[0045] like Figures 1-6 As shown, a fabric conveying correction device is illustrated in another embodiment of this disclosure, wherein a knob 46 is fixedly mounted on the outer side of the connecting block 43, and the knob 46 is located on the outer side of the threaded ring 42.

[0046] In some examples, rotating the knob 46 causes the threaded ring 45 to rotate, which in turn causes the retaining ring 47 to move inward, bringing the retaining ring 47 into contact with the elastic ring 44.

[0047] like Figures 1-6As shown, it illustrates a fabric conveying correction device in another embodiment of the present disclosure, wherein the cross-section of the elastic ring 44 is a right trapezoid, the cross-section of the retaining ring 47 is an inverted right triangle, and the inclined surface of the elastic ring 44 corresponds to the inclined surface of the retaining ring 47.

[0048] In some examples, the retaining ring 47 contacts the inclined surface of the elastic ring 44, causing the retaining ring 47 to compress the elastic ring 44, causing the elastic ring 44 to contract inward.

[0049] like Figures 1-6 As shown, it illustrates a fabric conveying correction device in another embodiment of the present disclosure. The placement mechanism 3 also includes a long plate 31 fixedly connected to the left end of the platform 1. The surface of the long plate 31 is provided with a placement groove 33. The two ends of the fabric roller 32 are fixedly installed with rods 34 located inside the placement groove 33.

[0050] In some examples, the fabric roller 32 is secured by placing the rod 34 directly inside the placement slot 33, which facilitates its use.

[0051] like Figures 1-6 As shown, it illustrates a fabric conveying correction device in another embodiment of the present disclosure. Photoelectric sensors 614 are movably mounted on the top of the platform 1 on both sides of the U-shaped frame 604. The photoelectric sensors 614 are respectively mounted on both sides of the platform 1.

[0052] In some examples, the position of the fabric is detected by a photoelectric sensor 614, which, together with a PLC and controller, achieves automatic correction.

[0053] Working principle and usage process of this utility model:

[0054] In use, the fabric is first passed through roller 613 to the outside of the collecting device 7, and then processed by the processing device 2. When the photoelectric sensor 614 detects that the fabric has deviated, it releases an electrical signal to the PLC. The PLC receives the signal from the photoelectric sensor 614 and transmits it to the controller, which in turn drives the hydraulic cylinder 602 to run. The hydraulic cylinder 602 drives the telescopic rod 603 to run, which in turn drives the U-shaped frame 604 to move upward. This causes roller 610 to move upward and lift the fabric. At this time, the servo motor 608 runs and drives the rotating shaft 609 to rotate. The rotating shaft 609 drives the disc 606 to rotate, which in turn drives the U-shaped frame 604 to rotate, causing roller 610 to deflect, thereby calibrating and correcting the fabric.

[0055] After the fabric is wrapped around the surface of the fabric roller 32, the fabric roller 32 is slid so that the bottom ring block 41 slides on the outside of the fabric roller 32, so that the bottom ring block 41 contacts the fabric. Then, the knob 46 is rotated so that the knob 46 rotates inside the threaded groove ring 42, thereby driving the threaded ring 45 to move inward, causing the retaining ring 47 to move inward and squeeze the outer wall of the elastic ring 44. The elastic ring 44 is compressed inward by the squeezing force of the retaining ring 47, so that the elastic ring 44 clamps and fixes the outer wall of the fabric roller 32, thereby positioning the position of the fabric through the positioning mechanism 4.
