Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of textiles, and particularly relates to a fabric weft straightening device. BACKGROUND

[0002] During the scouring, bleaching and printing processes, the fabric is subjected to many times of mechanical warp tension, which causes the warp elongation and the weft shrinkage of the fabric, resulting in phenomena such as uneven width, uneven selvedge, and weft skewing. In order to improve the quality of the fabric, the fabric must be subjected to setting treatment by a weft straightening machine. The weft straightening machine straightens the fabric through skewing rollers and bending rollers.

[0003] Patent No. CN222160730U discloses a camera weft straightening machine capable of trimming edges, comprising a support seat, a movable seat movably arranged on the top of the support seat, a deviation correction sensor installed on one side of the movable seat for detecting the edge position of the fabric, and a machine body arranged on the top of the movable seat.

[0004] The above patent can accurately adjust the position of the fabric, ensure the straightness and alignment of the fabric, and effectively identify foreign matter or defects on the fabric through scanning of the fabric surface by the CCD camera, and clean the fabric by cooperating with the cleaning assembly, thereby ensuring the quality of the fabric before entering the next process. However, the CCD camera is equidistantly installed on the bending plate and cannot be adjusted at will, resulting in limitations in shooting, which needs to be improved. SUMMARY

[0005] The application aims to provide a fabric weft straightening device capable of solving the above problems.

[0006] The application aims to provide a fabric weft straightening device, comprising a support seat;

[0007] An alignment mechanism, comprising a movable seat arranged on the support seat, a deviation correction sensor arranged on one side of the movable seat for detecting the edge position of the fabric, and a driver for driving the movable seat to move;

[0008] A workbench arranged on the top of the movable seat, wherein the top of the workbench is provided with an inlet, and the top of the workbench is sequentially provided with a straight roller, a bending roller, a width opening roller and a guide roller from top to bottom;

[0009] Further comprising a detection mechanism arranged above the workbench, comprising a CCD camera for collecting the appearance of the fabric, a support frame for installing the CCD camera, and a fixing structure for fixing the CCD camera;

[0010] A cleaning and dust collection mechanism arranged below the CCD camera for cleaning when foreign matter is detected;

[0011] The support frame is further provided with a turnover frame and a first conveying roller, and the turnover frame is provided with a second conveying roller.

[0012] The fabric whole-weft equipment can accurately adjust the position of the fabric by setting the alignment mechanism. The deviation correction sensor can detect the edge position of the fabric in real time, and the driver drives the moving seat to move according to the feedback of the sensor, thereby ensuring the straightness and alignment of the fabric, and helping to maintain the consistency and accuracy of the fabric in the subsequent process. The CCD camera in the detection mechanism is used to collect the appearance image of the fabric, which can capture the tiny defects or foreign matters on the fabric. The adjustable CCD camera is realized by the setting of the fixing structure, thereby expanding the shooting range and reducing the limitations of shooting. This helps to improve the comprehensiveness and accuracy of fabric quality detection.

[0013] The turnover frame and the first conveying roller provided on the support frame, and the second conveying roller on the turnover frame provide more flexibility for the processing of the fabric, so that the equipment can adapt to different types and specifications of fabric, and improve the versatility and applicability of the equipment. At the same time, the cleaning and dust collection mechanism is located below the CCD camera, which can immediately clean when the CCD camera detects foreign matters on the fabric. The automatic cleaning function not only improves the cleaning efficiency of the equipment, but also helps to maintain the continuous and stable operation of the equipment.

[0014] By integrating the alignment, detection, cleaning and other functions, the equipment can significantly improve the overall efficiency of fabric whole-weft. At the same time, the automatic operation process reduces the need for manual intervention and reduces the possibility of human error.

[0015] Further, the fixing structure comprises:

[0016] A support plate is provided with a mounting table on the top, and the CCD camera is installed on the mounting table;

[0017] A positioning rod is arranged on the workbench;

[0018] A clamping assembly comprises a first arc piece arranged at the bottom of the support plate, and a second arc piece and a third arc piece are hingedly arranged at both ends of the first arc piece;

[0019] A fastening assembly is connected with the second arc piece and the third arc piece, and is used to fix the clamping assembly on the positioning rod;

[0020] The curvature of the first arc piece, the second arc piece and the third arc piece is matched with the curvature of the positioning rod.

[0021] The mounting table at the top of the support plate provides a mounting base for the CCD camera, ensuring the stability of the camera during shooting, which helps to reduce image blur or distortion caused by camera shaking, thereby improving the quality of image acquisition. Through the arrangement of the clamping assembly, the fixing structure allows the CCD camera to adjust the left and right positions on the positioning rod. The curvature of the first arc piece, the second arc piece, and the third arc piece is adapted to the curvature of the positioning rod, so that the clamping assembly can closely fit the positioning rod and be flexibly and quickly installed and separated from the positioning rod through the hinged connection. At the same time, the connection design of the fastening assembly with the second arc piece and the third arc piece allows the clamping assembly to be easily fixed on the positioning rod, while also facilitating disassembly and reinstallation, simplifying the camera installation and debugging process, and improving work efficiency.

[0022] The design of the fixing structure makes it more convenient to maintain and replace the CCD camera. When the camera needs to be cleaned, repaired, or replaced, the worker can easily disassemble the clamping assembly or move the clamping assembly through the fastening assembly, reducing maintenance costs and improving the reliability and service life of the equipment.

[0023] Further, the fastening assembly includes:

[0024] The first mounting piece is arranged on the second arc piece;

[0025] The second mounting piece is arranged on the third arc piece;

[0026] The connecting rod is hingedly connected to the first mounting piece at one end and has a threaded end at the other end;

[0027] The fastening head is threadedly connected to the connecting rod;

[0028] The first mounting piece and the second mounting piece are both provided with through slots for the movement of the connecting rod.

[0029] The first mounting piece and the second mounting piece have a certain gap and are parallel to each other. During use, only the fastening head needs to be loosened, the connecting rod is turned from the first mounting piece to the second mounting piece through the through slot, and the fastening head is gradually tightened to make the fastening head contact the second mounting piece, so that the first mounting piece and the second mounting piece gradually approach each other, and finally the second arc piece and the third arc piece of the clamping assembly wrap the positioning rod, completing the positioning and installation of the detection structure.

[0030] Further, the positioning rod is provided with a positioning protrusion, and the bottom of the first arc piece is provided with a limiting guide groove adapted to the positioning protrusion.

[0031] The matching design of the positioning convex and the limiting guide groove ensures the accurate positioning of the clamping assembly on the positioning rod, effectively prevents the camera position from deviating due to vibration or external force interference, improves the stability and accuracy of shooting, and can also provide horizontal guidance for the movement of the detection mechanism and prevent accidental falling.

[0032] Further, the fastening head is provided with a support pad ring in contact with the second mounting sheet.

[0033] The addition of a support pad ring in contact with the second mounting sheet on the fastening head can disperse the fastening force during tightening, ensuring stable clamping of the clamping assembly on the positioning rod, and helping to reduce deformation or loosening of parts caused by uneven fastening force, thereby improving the stability of the entire fixing structure. At the same time, direct contact between the fastening head and the second mounting sheet during tightening may cause friction, resulting in surface wear of the parts. The use of a support pad ring can effectively reduce this friction and protect the surface of the parts from damage, extending the service life of the equipment.

[0034] Further, the cleaning dust collection mechanism comprises a support upright plate arranged on the top of the workbench and a plurality of dust collection nozzles arranged on the support upright plate, and the support upright plate is located on both sides of the material inlet.

[0035] The arrangement of multiple dust collection nozzles can cover a wider surface of the cloth, effectively adsorbing dust, lint and other small foreign matter on the cloth, improving the cleaning efficiency and ensuring the cleanliness of the cloth before entering the subsequent process. Arranging the cleaning dust collection mechanism on both sides of the material inlet can ensure that cleaning starts as soon as the cloth enters the working area, helping to remove foreign matter on the surface of the cloth in time and prevent quality problems in the subsequent process.

[0036] The beneficial effects of the present application are:

[0037] 1. The present application realizes the adjustability of the CCD camera through the arrangement of the fixing structure, thereby expanding the shooting range and reducing the limitations of shooting. This helps to improve the comprehensiveness and accuracy of cloth quality detection;

[0038] 2. The cleaning dust collection mechanism is located below the CCD camera, which can immediately clean when the CCD camera detects foreign matter on the cloth. The automatic cleaning function not only improves the cleaning efficiency of the equipment, but also helps to maintain the continuous and stable operation of the equipment;

[0039] 3. By integrating multiple functions such as alignment, detection and cleaning, the device can significantly improve the overall efficiency of fabric weft alignment. At the same time, the automatic operation process reduces the need for human intervention and reduces the possibility of human error. BRIEF DESCRIPTION OF DRAWINGS
