Description

Technical Field

[0001] This invention relates to the field of fabric inspection technology, specifically a defect detection device for processing one-piece fleece textile fabrics. Background Technology

[0002] One-piece fleece fabric offers excellent warmth retention and is characterized by its soft feel, wrinkle resistance, and shrinkage resistance. One-piece fleece has the fleece directly bonded to the inner layer of the fabric; it is not created through secondary processing that stitches the fleece to the fabric. This integrated structure ensures a tight fit between the fleece and the fabric, preventing shifting or shedding.

[0003] One-piece fleece fabric is mainly used for making close-fitting garments. The fleece surface fits snugly against the skin, providing excellent warmth. During the production process, the depth of the fleece pile needs to be tested to ensure the consistency of the pile length. Most existing testing methods can only perform sampling tests and cannot conduct continuous testing during production. Furthermore, it is impossible to repair defects simultaneously.

[0028] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0029] like Figure 1As shown, a defect detection device for processing integrated fleece textile fabric includes a base 1, with frames 10 fixedly arranged on both sides of the base 1, and a flipping frame 12 arranged between the frames 10. Winding drums 11 are rotatably installed on the two frames 10 respectively, and fabric is wound between the winding drums 11. A blowing assembly 3 is installed on the base 1 at the bottom of the fabric. A detection frame 6 is installed on the flipping frame 12. When the detection frame 6 is flipped to a horizontal state, it faces the blowing assembly 3. A fleece loosening assembly 4 and a detection mechanism 5 are arranged inside the detection frame 6.

[0030] like Figure 9 , Figure 10 , Figure 11 As shown, the detection mechanism 5 includes a detection box 50, with a base plate 500 at the bottom of the detection box 50. A first detection groove 501 and a second detection groove 502 are provided on the base plate 500. A reciprocating cutter 560 and a reciprocating cutter 561 are respectively provided on the base plate 500 at the corresponding positions of the first detection groove 501 and the second detection groove 502. A conduit 51 is provided on the upper side of the detection box 50, and a collection cylinder 52 is connected to the end of the conduit 51. A suction pump is provided inside the collection cylinder 52. Two sets of detection mechanisms 5 are continuously arranged, and an air permeability detection membrane 53 is connected between the two sets of detection mechanisms 5. Small holes are evenly arranged on the air permeability detection membrane 53, and an indicator strip for displaying the airflow status below is connected to the small holes.

[0031] Specifically, the integrated fleece is released and retrieved through winding drums 11 at both ends, with the fleece side facing upwards. When the fleece reaches the detection mechanism 5, it is caught between the blowing assembly 3 and the detection frame 6. First, the longer fleece fibers that are flattened and stuck inside the fabric are blown out by the fleece loosening assembly 4. The detection mechanism 5 then detects the longer fleece fibers. During the detection process, the fabric carrying the loosened fleece fibers moves into the bottom of the detection box 50. Combined with the blowing assembly 3 at the bottom, the fleece fibers pass through the bottom plate 500 and enter the first detection groove 501 and the second detection groove 502. The cutter 560 and cutter 561 inside the detection box 50 cut off the portion longer than the standard fleece length. The cut fleece fibers are then collected into the collection cylinder 52 via the guide tube 51 and the suction pump. The processing qualification rate of the integrated fleece fabric is determined by observing the amount of fleece collected in the collection cylinder 52.

[0032] More specifically, the testing mechanism 5 is set up in two sets to further avoid the problem of missed detection caused by the gap between the first testing slot 501 and the second testing slot 502. At the same time, a breathable testing membrane 53 is set between the two sets of testing mechanisms 5. When the airflow delivered to the fabric by the bottom blowing component 3 reaches the upper breathable testing membrane 53, the breathability of the one-piece fleece fabric is judged according to the fluttering effect of the indicator strip in the small hole of the breathable testing membrane 53, so as to realize the detection of the fleece length and the breathability of the fabric at the same time.

[0033] To ensure reliable fabric conveying and testing, pressure rollers 20 and support cylinders 21 are installed on the upper and lower sides of the fabric, respectively. The fabric is clamped during conveying to ensure reliable flatness, prevent wrinkles, and guarantee reliable testing.

[0034] While detecting fabric defects, the aforementioned testing agency 5 will repair the defective parts to avoid rework of the fabric later. It can also monitor the entire production process of the fabric to ensure the overall quality of the one-piece fleece fabric.

[0035] Furthermore, such as Figure 6 , Figure 7 As shown, the loosening component 4 includes pulleys 42 rotatably mounted on both sides of the detection frame 6. A connecting belt 40 is wound around the pulleys 42. Teeth 41 are evenly distributed on the outer side of the connecting belt 40. Two sets of connecting belts 40 are arranged in parallel. A driven bevel gear 43 is provided on the pulley 42 between the connecting belts 40. A driving bevel gear 44 meshes between the driven bevel gears 43. The driving bevel gear 44 is connected to a drive motor 46. The drive motor 46 is fixedly mounted on the detection frame 6.

[0036] Specifically, the driven bevel gear 43 and the driving bevel gear 44 between the pulleys 42 achieve reverse transmission control of the two connecting belts 40. Combined with the prying teeth 41 on the connecting belts 40, the longer fibers hidden in the fabric are pried up. With the cooperation of the blowing assembly 3, the longer fibers float upward at a vertical angle with the fabric, which is convenient for subsequent testing by the testing mechanism 5.

[0037] Furthermore, such as Figure 5 As shown, the flipping frame 12 is provided with two sets of connecting frames 13, and the two sets of connecting frames 13 are fixedly connected to both sides of the detection frame 6 respectively. A lifting frame 14 is horizontally arranged on the flipping frame 12, and the lifting frame 14 is slidably installed between the flipping frame 12 and the flipping frame 12. A lifting motor 15 is fixedly arranged on the flipping frame 12, and the lifting motor 15 is connected to the lifting frame 14. A flipping motor is provided at the rotational connection part between the flipping frame 12 and the frame 10.

[0038] Specifically, the connecting frame 13 is vertically mounted between the detection frame 6 and the flipping frame 12, facilitating adaptive adjustments based on the pile length of the integrated fleece fabric. This ensures that the bottom of the detection mechanism 5 aligns with the ends of the fabric pile during detection, thereby detecting and removing defects such as pile exceeding the standard length. The detection frame 6, along with its internal pile loosening component 4 and the detection mechanism 5, is connected to the flipping frame 12, facilitating the installation of the integrated fleece fabric.

[0039] Furthermore, such as Figure 2 , Figure 3 As shown, the blower assembly 3 includes two sets of mounting slide rails 31 arranged parallel to each other on the base 1. Two sets of connecting sliders 32 are slidably mounted on each set of mounting slide rails 31. A support rod 33 is rotatably mounted on the connecting slider 32. The end of the support rod 33 away from the connecting slider 32 is connected to a blower box 30. A filter screen 35 is provided on the upper side of the blower box 30. A fan 34 is provided on the side of the blower box 30. An intermediate frame 36 is provided between the mounting slide rails 31. A lifting motor 37 is provided on the frame 10. The lifting motor 37 is connected to the bottom of the blower box 30.

[0040] Specifically, during testing, the lifting motor 37 drives the blower box 30 to rise and press against the bottom of the fabric. All the airflow generated inside the blower box 30 acts on the bottom of the fabric, ensuring the testing effect of the fabric.

[0041] Furthermore, such as Figure 4 As shown, the blower box 30 and the detection frame 6 are provided with a bonding part on the side facing the fabric. The bonding part includes a bonding roller 38. The two ends of the bonding roller 38 are rotatably installed between the mounting block 39 and the mounting block 39. The mounting block 39 is vertically slidably engaged. The mounting block 39 is provided with a plug post 310. A fixing block 312 is inserted through the plug post 310. A support spring 311 is sleeved between the plug post 310 and the fixing block 312.

[0042] Specifically, in order to ensure the effective cooperation between the blower assembly 3 and the detection frame 6, the detection frame 6 and the bottom blower box 30, when approaching the fabric, respectively cooperate with the side-mounted bonding roller 38 to approach the fabric, ensuring that the detection frame 6 and the blower box 30 reliably approach the fabric while avoiding excessive clamping force on the fabric, which would affect the continuous conveying and detection of the fabric.

[0043] Furthermore, such as Figure 8As shown, adjustment frames 60 are provided on both sides of the detection frame 6, and mounting rods 61 are slidably engaged on the adjustment frames 60. The two ends of the detection box 50 are slidably installed between the mounting rods 61 and the detection frame 6. A lifting motor 62 is provided between the detection frame 6 and the mounting rods 61. A connecting plate 64 is provided between the mounting rods 61 of the adjustment frames 60 on both sides. A winding roller 65 is provided on the connecting plate 64. A pull cable 66 is wound on the winding roller 65. The pull cable 66 is connected to the side of the detection box 50. A support spring 63 is sleeved on the mounting rod 61 between the side of the detection box 50 and the detection frame 6.

[0044] Specifically, the ends of the two sets of detection mechanisms 5 are slidably installed between the mounting rod 61 and the winding roller 65 and the cable 66. The distance between the two sets of detection mechanisms 5 can be adjusted by combining them with the winding roller 65 and the cable 66, thereby providing more space for installing the breathability testing membrane 53. One end of the breathability testing membrane 53 is installed on the side of the detection box 50 in one of the sets of detection mechanisms 5 through the automatic recycling cylinder 54, so that the breathability testing membrane 53 can adaptively adjust the unfolded length according to the distance, which is convenient for visually displaying the breathability effect of the fabric.

[0045] Furthermore, such as Figure 10 , Figure 11 As shown, the first detection slot 501 and the second detection slot 502 are continuously staggered. The first cutter 560 and the second cutter 561 are connected to the moving frame 56. A fixed frame 57 is fixedly installed inside the detection box 50. A connecting plate 58 is installed on the fixed frame 57. A rotating frame 59 is installed on the connecting plate 58. A mating column 510 is installed at the end of the rotating frame 59. A power motor is connected to the rotating frame 59. A push-pull frame 512 is installed on the moving frame 56. A mating groove 511 is installed on the push-pull frame 512. The mating column 510 and the mating groove 511 are mated to each other.

[0046] Specifically, the lint on the fabric floats upward under the action of the blower assembly 3 and the lint loosening assembly 4. The longer lint enters the inspection box 50 when it passes the inspection box 50. Combined with the rotating frame 59 and the cooperating column 510, the push-pull frame 512 moves back and forth, which in turn drives the bottom moving frame 56 to move back and forth. The cutter 560 and cutter 561 on the moving frame 56 are controlled to perform back and forth cutting actions, thereby removing the longer lint that has entered the first inspection groove 501 and the second inspection groove 502, completing the inspection and defect elimination steps.

[0047] Furthermore, such as Figure 7As shown, a lifting slide 47 is provided inside the detection frame 6, a connecting slider 48 is provided at the end of the shaft of the pulley 42, the connecting slider 48 is slidably installed between the lifting slide 47, a supporting spring 49 is provided between the connecting slider 48 and the lifting slide 47, and a telescopic rod 45 is provided between the drive motor 46 and the active bevel gear 44.

[0048] Specifically, the connecting belt 40 and pulley 42 are mounted in conjunction with the connecting slider 48 and the lifting groove 47 for lifting and lowering. When the detection frame 6 is close to the fabric, the teeth 41 on the connecting belt 40 can reliably penetrate into the interior of the pile, thereby moving the longer pile fibers hidden inside. The teeth 41 are made of soft rubber to prevent damage to the fabric during movement.

[0049] The working principle of this invention embodiment is as follows: like Figures 1-11 As shown, when the pile reaches the detection mechanism 5, it is sandwiched between the blower assembly 3 and the detection frame 6. First, the longer pile fibers that are flattened and stuck inside the fabric are blown out by the pile loosening assembly 4. The detection mechanism 5 then detects the longer pile fibers. During the detection process, the loosened pile fibers on the fabric move and enter the bottom of the detection box 50. Combined with the blower assembly 3 at the bottom, the pile fibers pass through the bottom plate 500 and enter the first detection groove 501 and the second detection groove 502. The cutter 560 and cutter 561 inside the detection box 50 cut off the portion of pile fibers that are longer than the standard pile length. The cut pile fibers are then collected into the collection cylinder 52 by the guide tube 51 and the suction pump. The processing qualification rate of the integrated pile fabric is judged by observing the amount of pile fibers collected in the collection cylinder 52. A breathability testing membrane 53 is set between the two sets of testing mechanisms 5. When the airflow delivered to the fabric by the bottom blowing component 3 reaches the upper breathability testing membrane 53, the breathability of the one-piece fleece fabric is judged based on the fluttering effect of the indicator strip in the small hole of the breathability testing membrane 53, thereby realizing the detection of the fabric's breathability while detecting the fleece length.
