Description

Technical Field

[0001] This utility model relates to the field of fabric production and testing technology, and in particular to an automatic edge detection auxiliary device for fabric inspection machines. Background Technology

[0002] For example, Chinese patent CN217201178U discloses an automatic edge detection auxiliary device for a fabric inspection machine. By adjusting the infrared edge detectors on both sides, it can transport fabrics of different widths, which is highly practical. By adjusting the height of the device, it can meet different usage needs and has a wide range of applications.

[0003] However, the detection device in the above application detects the position of the fabric edge using an infrared edge detector. Infrared edge detectors are easily affected by light interference. For some dark-colored or glossy fabrics, the detection effect will be greatly reduced, resulting in a decrease in detection accuracy. In addition, the fabric may have local wrinkles during the transportation process, causing the infrared edge detector to frequently report errors. Workers need to repeatedly straighten the fabric, which affects the detection efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic edge detection auxiliary device for fabric inspection machines, which solves the technical problem that existing infrared edge detectors are easily affected by optical interference, leading to a decrease in detection accuracy, and thus achieves the goal of improving detection accuracy.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic edge detection auxiliary device for a fabric inspection machine, including a crossbeam installed on a connecting frame, an edge detection mechanism for detecting the edge of the fabric on the crossbeam, and a fabric laying mechanism for flattening the fabric on the connecting frame.

[0006] The side detection mechanism includes a bidirectional motor installed on the top of the crossbeam, and both output ends of the bidirectional motor are connected to lead screws. The lead screws are threadedly connected to threaded slide plates that slide left and right in guide grooves opened on the crossbeam. The two rotating holes opened on the threaded slide plates are rotatably connected to rotating shafts. Rollers are installed on the rotating shafts, and electrical contacts are installed in the mounting slots opened in a circular array on the rollers.

[0007] A further improvement is that the threaded slide plate has a through groove, and the inside of the through groove has symmetrical strip grooves. A bearing block is slidably connected to the through groove, and the upper rotating shaft is rotatably connected to the bearing block. Slider blocks that are slidably connected to the strip grooves are installed on both sides of the bearing block.

[0008] A further improvement is that the fabric laying mechanism includes a fixed bearing mounted on a connecting frame, and a rotating shaft is rotatably connected inside the fixed bearing. A laying roller is mounted on the rotating shaft. An electrostatic generator is installed in the mounting cavity opened inside the laying roller, and an electrostatic sleeve electrically connected to the electrostatic generator is sleeved on the laying roller. A dust-collecting component is provided on the connecting frame to remove dust and impurities from the fabric.

[0009] A further improvement is that the fabric laying mechanism is installed at an angle on the connecting frame, and the two laying rollers form a V-shape.

[0010] A further improvement is that the vacuuming assembly includes a vacuum cleaner mounted on a crossbeam, and the vacuum cleaner's air inlet is equipped with an air suction pipe, a diverter pipe is installed at the bottom of the air suction pipe, and a vacuum hood is installed at the bottom of the diverter pipe.

[0011] A further improvement is that the dust collection component is located between the opposite edge detection mechanism and the fabric laying mechanism, and a tension roller is rotatably connected to the connecting frame and the rotating hole located below the dust collection hood.

[0012] By employing the above technical solution, this utility model provides an automatic edge detection auxiliary device for a fabric inspection machine, which has at least the following beneficial effects:

[0013] 1. This utility model uses a bidirectional motor to drive the lead screw to rotate, thereby causing the threaded slide plate to slide relative to the guide groove, clamping the fabric between two rollers. If the fabric has wrinkles or uneven edges, resulting in no fabric obstruction between the two rollers, the electrical contacts on the rollers will contact and send an electrical signal alarm, thereby realizing the detection of the fabric's edge alignment.

[0014] 2. This utility model uses two V-shaped flat-laying rollers to guide the fabric to both sides, thereby smoothing out the wrinkles in the fabric. During this process, an electrostatic generator is activated, and an electrostatic sleeve is used to remove static electricity from the fabric, which facilitates the subsequent edge inspection of the fabric.

[0015] 3. This utility model uses a vacuum cleaner with a suction pipe and a split pipe to remove dust from the cloth after static electricity has been removed. Because the static electricity on the cloth has been removed, as the suction force generated by the vacuum hood causes the cloth to vibrate, the dust and impurities on the other side of the cloth will also be shaken off.

[0028] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] To address the issue that existing infrared edge detection instruments are susceptible to optical interference, leading to decreased detection accuracy, this embodiment provides an automatic edge detection auxiliary device for fabric inspection machines. Please refer to [reference needed]. Figures 1-5This embodiment provides an automatic edge alignment detection auxiliary device for a fabric inspection machine, which can improve detection accuracy. The device includes a crossbeam 2 mounted on a connecting frame 1, an edge alignment detection mechanism 3 for detecting the edges of the fabric on the crossbeam 2, and a fabric flattening mechanism 4 for flattening the fabric on the connecting frame 1. The edge alignment detection mechanism 3 detects the edges of fabrics of different widths and thicknesses, while the fabric flattening mechanism 4 flattens the fabric, making it easier for the edge alignment detection mechanism 3 to perform edge alignment detection.

[0031] Because existing infrared edge detectors are susceptible to optical interference, leading to a decrease in detection accuracy, this device is equipped with an edge detection mechanism 3. The edge detection mechanism 3 includes a bidirectional motor 31 installed on the top of the crossbeam 2, and both output ends of the bidirectional motor 31 are connected to lead screws 32. The lead screws 32 are threadedly connected to threaded slide plates 33 that slide left and right in guide grooves opened on the crossbeam 2. The two rotating holes opened on the threaded slide plates 33 are rotatably connected to rotating shafts 34. Rollers 35 are installed on the rotating shafts 34, and electrical contacts 36 are installed in the mounting grooves opened in a ring array on the rollers 35.

[0032] The threaded slide plate 33 has a through groove, and symmetrical strip grooves are formed inside the through groove. A bearing block 37 is slidably connected to the through groove, and a rotating shaft 34 located above is rotatably connected to the bearing block 37. Slider blocks 38 are installed on both sides of the bearing block 37 and are slidably connected to the strip grooves. Depending on the width of the fabric, the bidirectional motor 31 is started to drive the two lead screws 32 to rotate, thereby causing the two threaded slide plates 33 on the lead screws 32 to slide relative to each other along the guide grooves until the two sides of the fabric touch the threaded slide plates 33. Then, the roller 35 located above the threaded slide plate 33 is lifted, causing the bearing block 37 to move up and down in the through groove. The sliding mechanism, in which the slider 38 and the slot cooperate to prevent the bearing block 37 from falling out of the slot, allows the fabric to pass between the two rollers 35. The upper roller 35 is then released, and under gravity, it falls to engage with the lower roller 35 to hold the fabric in place. The friction generated by the fabric's winding causes the two rollers 35 to rotate. If the fabric wrinkles or has uneven edges, resulting in no fabric obstruction between the two rollers 35, the electrical contacts 36 on the rollers 35 will contact each other, sending an electrical signal to the external control panel to notify that the fabric has uneven edges and needs immediate attention.

[0033] Example 2

[0034] Based on Example 1, such as Figures 1-5As shown, since the fabric may have local wrinkles during the conveying process, the infrared edge detector will frequently report errors, requiring workers to repeatedly flatten the fabric, which affects the detection efficiency. Therefore, the device is also equipped with a fabric flattening mechanism 4. The fabric flattening mechanism 4 includes a fixed bearing 41 installed on the connecting frame 1, and a rotating shaft 42 is rotatably connected inside the fixed bearing 41. A flattening roller 43 is installed on the rotating shaft 42. An electrostatic generator 44 is installed in the installation cavity opened inside the flattening roller 43, and an electrostatic sleeve 45 electrically connected to the electrostatic generator 44 is sleeved on the flattening roller 43. A dust suction component 46 is provided on the connecting frame 1 to remove dust and impurities from the fabric.

[0035] The fabric laying mechanism 4 is installed at an angle on the connecting frame 1. The two laying rollers 43 form a V-shape. During the winding and inspection process, the fabric passes through the laying rollers 43. Because the two laying rollers 43 are installed in a V-shape, the fabric is guided to both sides, thereby smoothing out the wrinkles in the fabric. During this process, the electrostatic generator 44 is activated, and the electrostatic sleeve 45 sleeved on the laying rollers 43 removes the static electricity from the fabric, which facilitates the subsequent edge inspection of the fabric.

[0036] Example 3

[0037] Based on Example 2, such as Figures 1-5 As shown, since there are often loose threads and dust impurities on the fabric, the device is also equipped with a dust collection component 46. The dust collection component 46 includes a vacuum cleaner 461 installed on the crossbeam 2, and a suction pipe 462 is installed at the suction port of the vacuum cleaner 461. A diverter pipe 463 is installed at the bottom of the suction pipe 462, and a dust collection hood 464 is installed at the bottom of the diverter pipe 463. When the vacuum cleaner 461 is started, the dust on the fabric after static electricity has been removed is sucked away through the cooperation of the suction pipe 462 and the diverter pipe 463, and then through the dust collection hood 464. Since the static electricity on the fabric has been removed, as the dust collection hood 464 generates suction to drive the fabric to vibrate, the dust and impurities on the other side of the fabric will also be shaken off.

[0038] The dust collection component 46 is located between the edge detection mechanism 3 and the fabric laying mechanism 4, and a tension roller 47 is rotatably connected to the rotating hole opened on the connecting frame 1 below the dust collection hood 464. The fabric is pressed under the tension roller 47 for rolling conveying, thereby preventing the suction force generated by the dust collection hood 464 during the dust collection process from sucking the fabric into it and affecting the fabric conveying and detection.
