Description

Technical Field

[0001] This utility model relates to the field of fabric inspection technology, and in particular to an automatic fabric defect detection instrument. Background Technology

[0002] Fabric testing refers to the process of testing, analyzing, and evaluating multiple performance, characteristics, and quality-related indicators of fabrics using various professional technical means and equipment. It covers a wide range of testing contents, including physical properties, chemical characteristics, and appearance quality. By testing the physical performance indicators of fabrics, such as strength and abrasion resistance, it is possible to determine whether the fabric meets the corresponding quality standards. Strict fabric testing helps to screen out fabrics with quality problems in the early stages of production, preventing them from entering subsequent production stages and reducing the number of defective finished products due to fabric defects. From the sales perspective, it can also reduce the rate of returns by consumers due to fabric quality problems, thus maintaining brand image and corporate reputation.

[0003] To quickly process large volumes of inspection tasks, meet high-speed production requirements, and reduce the limitations of manual inspection, actual fabric inspection often requires the use of automatic inspection instruments. Automatic inspection instruments can achieve rapid real-time inspection and long-term continuous operation, effectively reducing labor costs. However, most existing automatic inspection instruments use a transmission roller structure, which means that the fabric is mostly without tension and in a soft state during inspection. This can lead to inaccurate inspection structures when inspecting certain types of fabric, resulting in reduced inspection accuracy and increased inspection costs. Utility Model Content

[0022] 1. In this utility model, the fixed plate and fixed seat are first pulled out of the testing machine through the cooperation of the sliding groove and pulley. Then, the fabric is placed on the fixed plate, with both ends of the fabric placed on the two rotating wheels. The hydraulic rod is activated, and its output squeezes the fixed shaft downward, causing the fixed shaft to drive the pressing wheel to slide down, clamping the fabric between the pressing wheel and the rotating wheel. Then, the two rotating discs are rotated in opposite directions, and the extension wheel drives the rotating wheel to rotate in opposite directions, so that the fabric is tightened by lateral tension. Then, the rotating disc is slid backward, and the locking block is locked into the nearest locking slot to fix the rotation angle of the rotating wheel. Finally, the fixed plate is pushed back into the testing machine for testing, thereby achieving the purpose of increasing the tension of the fabric, improving the accuracy of the test, and reducing the testing cost.

[0023] 2. In this utility model, after the fixed plate is pushed back into the testing machine, the baffle can be rotated by the connecting rod to reverse the baffle and end the obstruction of the ventilated plate. Then, the dust removal fan is started. Under the output of the dust removal fan, the dust inside the testing machine and the dust on the fabric are blown away and discharged out through the holes of the ventilated plate. After the dust removal fan is used, the position of the baffle is restored to prevent the ventilated plate from blocking dust from entering the testing machine. Then the testing begins. The dust curtain on the front of the testing machine allows the fixed plate to pass through while blocking some dust from entering from the front of the testing machine, thereby achieving the purpose of dust prevention and dust removal and increasing the practicality of the testing instrument.

[0038] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 The outer wall of the vent plate 204 is provided with multiple threaded holes 25. The inner wall of the threaded hole 25 is threadedly connected to a threaded rod 24. A gasket 23 is slidably connected to the rear side of the outer wall of the threaded rod 24.

[0039] Specifically, the outer wall of the vent plate 204 has a threaded hole 25, and the inner wall of the threaded hole 25 is firmly threadedly connected to the threaded rod 24. Furthermore, the rear side of the outer wall of the threaded rod 24 is connected to the gasket 23 through a sliding connection, ensuring flexible movement between the two. The middle part of the outer wall of the threaded rod 24 is also connected to the positioning plate 22 through a sliding connection, ensuring that the positioning plate 22 is fixed in position. The middle part of the outer wall of the testing machine 1 is tightly connected to the front side of the outer wall of the positioning plate 22 through a rotational connection, so that the positioning plate 22 can rotate flexibly.

[0040] Working principle: When fabric defects need to be detected, the fixed plate 6 and fixed seat 7 are first pulled out of the inspection machine 1 through the cooperation of the slide 3 and pulley 5. Due to the structural limitation of the slide 3, the pulley 5 cannot completely disengage from the slide 3, thus preventing the fixed plate 6 from detaching from the inspection machine 1. Then, the fabric is placed on the fixed plate 6, with both ends of the fabric placed on the rotating wheels 11 on both sides. Then, the hydraulic rod 8 is activated, and the hydraulic rod 8 outputs downward pressure on the fixed shaft 10, causing the fixed shaft 10 to drive the pressing wheel 9 along the inside of the fixed seat 7. The groove of the part slides down, thereby clamping the fabric between the pressing wheel 9 and the rotating wheel 11. After clamping, the output of the hydraulic rod 8 can be stopped. Then the turntables 14 on both sides are rotated in the opposite direction, thereby driving the rotating wheel 11 to rotate in the opposite direction through the extension wheel 12, so that the fabric is subjected to lateral tension and is tightened. Then the turntable 14 slides backward, driving the extension wheel 12 and the locking block 13 to slide backward, so that the locking block 13 is locked into the nearest locking groove 15, thereby fixing the rotation angle of the rotating wheel 11. Then the fixing plate 6 is pushed back into the testing machine 1 for testing.

[0041] When testing fabrics, dust on the fabric surface may affect the test results. In this case, dust prevention and dust removal can be performed through the dustproof mechanism 2. After the fixed plate 6 is pushed back into the testing machine 1, the baffle 208 can be rotated by the connecting rod 207 to reverse the baffle 208 and end the obstruction of the breathable plate 204. Then, the dust removal fan 203 is started. Under the output of the dust removal fan 203, the dust inside the testing machine 1 and the dust on the fabric are blown away and discharged out through the holes of the breathable plate 204. After the dust removal fan 203 is used, the position of the baffle 208 is restored so that it blocks the breathable plate 204 to prevent dust from entering the testing machine 1. Then the test begins. The dustproof curtain 202 on the front of the testing machine 1 allows the fixed plate 6 to pass through while blocking some dust from entering from the front of the testing machine 1.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
