Description

Technical Field

[0001] The present invention relates to the technical field of cloth detection, and in particular to a non-woven fabric transmission tensile detection device and a detection method. Background Art

[0002] Non-woven fabrics have the advantages of high strength, good air permeability, and soft texture. They are important raw materials for the production of medical textiles such as masks and wet and dry wipes. In the actual production and manufacturing process of non-woven fabrics, quality inspection is crucial. At present, the mainstream non-woven paper material inspection process relies heavily on manual work, with high labor costs and low automation, making it difficult to improve efficiency.

[0003] However, there are usually some problems in the daily use of non-woven fabric transmission tensile testing devices. With the development of science and technology, technicians in related fields have also made a lot of optimizations on non-woven fabric transmission tensile testing devices to solve some problems that different consumer groups care about. In order to make a more accurate comparison, a Chinese patent with publication number CN219326945U discloses a non-woven fabric defect detection and winding-up integrated device, which specifically relates to the field of fabric detection technology. When in use, the non-woven fabric first bypasses the bottom of the feed roller and then bypasses the top of the two cloth-passing rollers. At this time, the non-woven fabric is located under the flat lamp. After turning on the light, the principle of light transmittance can be used to show the defects on the back of the fabric, which facilitates the capture of the defects by the CCD camera. The CCD camera transmits the image to the detection computer for comparison to determine whether the fabric has defects; thereby improving the efficiency of fabric quality detection and avoiding missed detection.

[0004] However, the above non-woven fabric defect detection and winding-integrated device still has the following shortcomings in actual use:

[0005] 1. The above-mentioned non-woven fabric defect detection and winding-up integrated device can reveal the defects on the back of the fabric by turning on the flat panel light and utilizing the principle of light transmittance, and captures the defects through a CCD camera. However, in this process, only transmission detection can be performed on the non-woven fabric and tensile detection cannot be performed at the same time. If tensile detection can be performed at the same time as transmission detection, the detection efficiency of the non-woven fabric can be greatly improved.

[0006] 2. The above-mentioned non-woven fabric defect detection and winding-up integrated device drives the cleaning rollers to rotate through a rotating motor. The two cleaning rollers clean the front and back sides of the non-woven fabric so as to brush off the dust or fluff on both sides of the non-woven fabric. However, when performing transmission detection, the dust or fluff on the surface of the non-woven fabric will affect the detection results, thereby affecting the detection quality.

The L-shaped collecting frame 450 is used to collect impurities on the non-woven fabric; a bar handle 451 is hingedly arranged at the top of the L-shaped collecting frame 450, a collecting brush 452 is arranged at the bottom of the bar handle 451, and the bar handle 45 When the oblique scraper 42 is moved, the L-shaped collecting rod 455 can be driven to move together, and the strip handle 451 can be pushed to rotate toward the fixed plate 453 through the L-shaped collecting rod 455.

[0059] During the specific implementation process, when the non-woven fabric is lifted up by the stretching column 25, the inclined scraper 42 will be driven to move. When the inclined scraper 42 moves, it can drive the L-shaped collecting rod 455 to move together. The L-shaped collecting rod 455 can push the strip handle 451 to rotate toward the fixed plate 453. When the strip handle 451 rotates, it can drive the collecting brush 452 to rotate together. When the collecting brush 452 rotates, it can sweep the impurities accumulated on the non-woven fabric into the L-shaped collecting frame 450, so as to realize centralized storage of the accumulated impurities and prevent the impurities from falling into the working environment and causing pollution to the working environment.

[0060] In addition, the present invention also provides a non-woven fabric transmission tensile test method, comprising the following steps:

[0061] Step 1: The operator winds the non-woven fabric to be tested on the discharge roller 11, and then pulls the non-woven fabric on the discharge roller 11 so that the non-woven fabric passes through the transmission roller 200 and is wound onto the receiving roller 12. The non-woven fabric to be tested is straightened through the cooperation of the discharge roller 11 and the receiving roller 12. In this process, the drive motor 210 is started. When the drive motor 210 rotates, it can drive one of the transmission shafts 20 to rotate. When one of the transmission shafts 20 rotates, it drives the other transmission shaft 20 to rotate together through the belt drive. When the transmission shaft 20 rotates, it can drive the bevel gear 2 13 rotates together, when the bevel gear 213 rotates, it can drive the bevel gear 1 212 to rotate together, when the bevel gear 1 212 rotates, it can drive the reciprocating screw 211 to rotate together, when the reciprocating screw 211 rotates, it can drive the square block 214 to move up and down, when the square block 214 moves, it can drive the strip plate 215 to move together, when the strip plate 215 moves, it can drive the triangular fixing block 216 to move together, when the triangular fixing block 216 moves, it enters the triangular groove 217, and the non-woven fabric is intermittently fixed by the cooperation of the triangular fixing block 216 and the triangular groove 217.

[0062] Step 2: While fixing the non-woven fabric, when the transmission shaft 20 rotates, it can drive the rotating shaft 2800 to rotate together, and when the rotating shaft 2800 rotates, it can drive the active disc 2802 to rotate together, and when the active disc 2802 rotates, it can drive the intermittent block 2803 to rotate together, and when the intermittent block 2803 rotates, it can drive the driven disc 280 to rotate intermittently through the cooperation with the arc groove 2804, and when the driven disc 280 rotates intermittently, it can drive the rotating shaft 23 to rotate intermittently, and when the rotating shaft 23 rotates intermittently, it can drive the fixed rod 27 to rotate together, and when the fixed rod 27 rotates, it can drive the connecting plate 26 to rotate together, and when the connecting plate 26 rotates, it can drive the tensile column 25 to rotate together, and when the tensile column 25 rotates, it can lift up the non-woven fabric that conflicts with it, thereby realizing the tensile test of the non-woven fabric.

[0063] Step 3: When the transmission shaft 20 rotates, it can drive the main shaft 282 to rotate together. When the main shaft 282 rotates, it can drive the spur gear 283 to rotate together. When the spur gear 283 rotates, it can drive the incomplete gear 284 to rotate together. When the incomplete gear 284 rotates, it can drive the push rod 285 to move together. When the push rod 285 moves, it can drive the rotating shaft 23 to move along the arc slide 220. When the rotating shaft 23 moves, it can drive the stretching column 25 to move together, thereby achieving different degrees of stretching of the non-woven fabric, thereby improving the detection quality.

[0064] Step 4: When the non-woven fabric passes through the square plate 40 through the strip-shaped through groove 41, the impurities on the non-woven fabric can be blocked by the inclined scraper 42, and the impurities will move along the inclined scraper 42 to cause the impurities to gather; when the non-woven fabric is lifted up by the stretching column 25, the inclined scraper 42 will be driven to move, and when the inclined scraper 42 moves, it can drive the L-shaped collecting rod 455 to move together, and the L-shaped collecting rod 455 can push the strip handle 451 to rotate toward the fixed plate 453, and when the strip handle 451 rotates, it can drive the collecting brush 452 to rotate together, and when the collecting brush 452 rotates, it can sweep the impurities accumulated on the non-woven fabric into the L-shaped collecting frame 450, so as to realize the centralized storage of the accumulated impurities and prevent the impurities from falling into the working environment and polluting the working environment.

[0065] Step 5: After the non-woven fabric is cleaned, turn on the square light board 30 so that the light from the square light board 30 is directed toward the non-woven fabric. Then, the non-woven fabric moves under the action of the transmission roller 200, and the defect points on the non-woven fabric are captured by the CCD camera 34 to achieve transmission detection of the non-woven fabric.
