Description

Technical Field

[0001] The utility model relates to an auxiliary detection mechanism for defects of non-woven fabrics for vehicles, belonging to the technical field of non-woven fabric defect detection. Background Art

[0002] Automobile non-woven fabric is a new generation of environmentally friendly materials, which is moisture-proof, breathable, flexible, lightweight, flame-retardant, heat-insulating, non-toxic, tasteless, and non-irritating. Non-woven fabrics are widely used in automobiles, such as car trunks, car seat cushions, and car roof sound insulation.

[0003] For example, CN218847998U discloses an auxiliary defect detection mechanism for non-woven fabrics for vehicles. Through the arrangement of non-woven fabric leveling equipment, non-woven fabric placement equipment and laser scanning equipment, the non-woven fabric will not tilt, which is convenient for the laser scanning equipment to detect defects. The laser scanning equipment can be used to determine whether a defect has occurred. However, when flattening the fabric, only the lower pressure roller and the protective pad are used to flatten the fabric by rolling and pressing down. There is no proper tension on both sides of the fabric to straighten the fabric. When the wrinkled fabric passes through the lower pressure roller and the protective pad, it is very likely to press on the wrinkled fabric again, resulting in poor flattening effect. Utility Model Content

[0004] The utility model aims to provide an auxiliary defect detection mechanism for non-woven fabrics for vehicles. By setting a bracket one and a bracket two, a rotating guide wheel is provided on the bracket one. The rotating guide wheel can drive the fabric to be straightened to both sides, so that the fabric can be pulled to both sides. When the fabric passes through a pressing plate, the pressing plate can scrape the fabric flat again, and the induced draft fan can generate negative pressure inside the air box, so that the air guide hole one and the air guide hole two can absorb the fabric, prevent the fabric from rebounding and resetting after being leveled, and improve the leveling effect of the fabric, so as to solve the problems raised in the above-mentioned background technology.

[0008] Furthermore, a plurality of rubber strips are provided at the bottom of the pressing plate, and the bottom of the rubber strips contacts the upper surface of the partition.

[0009] Furthermore, a plurality of air guide holes 1 are provided on one side above the partition, and a plurality of air guide holes 2 are provided on the other side above the partition located on the second bracket, and the air guide holes 1 and 2 run through the interior of the operating table.

[0010] Furthermore, a bellows is provided at the bottom of the operating table below the first and second air guide holes, an induced draft fan is provided inside the bellows, and an air outlet is provided at the bottom of the bellows.

[0011] Furthermore, a positioning screw is provided above the column, the bottom of the positioning screw is connected to the top plate, and the positioning screw is rotatably connected inside the top plate.
