Description

Technical Field

[0001] This utility model relates to the field of automatic roll-up equipment technology, specifically a novel automatic roll-up inspection machine for polyester-cotton fabric. Background Technology

[0002] In the textile industry, polyester-cotton fabric, as a blended fabric that combines the excellent properties of polyester and cotton, is widely used in clothing, home textiles, industrial fabrics and other fields due to its advantages such as high strength, good abrasion resistance and easy care.

[0003] A search revealed a Chinese patent with publication number CN221662129U, which discloses a winding device for producing polyester-cotton fabric. The device includes a base, an mounting plate fixedly connected to the upper left side of the base, a motor fixedly mounted on the left end of the mounting plate, an output end of the motor passing through the mounting plate and fixedly connected to a mounting disc, four right-angle rods fixedly connected to the right end of the mounting disc in a circular array, an adjusting rod fixedly connected to the middle of the right end of the mounting disc, a winding mechanism on the outer surface of the adjusting rod, and adjusting mechanisms on both the left and right sides of the winding mechanism.

[0004] However, existing fabric inspection methods mostly rely on manual visual inspection, which is not only labor-intensive and inefficient, but also easily affected by subjective factors such as the fatigue and experience level of the inspectors, resulting in a high rate of missed or false defects. This makes it difficult to meet the quality control requirements of large-scale production. Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The existing technologies mentioned above have shortcomings and defects, such as relying heavily on manual visual inspection, resulting in low inspection efficiency and a high false detection rate.

[0006] This utility model discloses a novel automatic roll-up inspection machine for polyester-cotton fabric, comprising a frame on which a detection component, a roll-up mechanism, a guide component, and a cleaning component are mounted. The detection component includes a housing, a slide plate slidably disposed inside the housing, guide members disposed between the two sides of the slide plate and the inner wall of the housing, a drive component disposed between the slide plate and the housing, lighting components mounted on both sides of the housing, and an industrial camera mounted at the lower end of the slide plate.

[0007] Furthermore, the guide includes a guide rail, which is fixedly installed on the inner wall of the housing. A groove is provided on the slide plate at the corresponding position of the guide rail. The guide rail is slidably disposed with the groove on the slide plate. The guide rail is configured as a "T" shape.

[0008] Furthermore, the driving component includes a lead screw, which is rotatably mounted on the housing and threadedly connected to the slide plate. One end of the lead screw passes through the housing and the frame, and the power end of the lead screw is provided with a drive source, which is mounted on the frame.

[0009] Furthermore, the lighting component includes a mounting bracket, which is fixedly mounted on the housing, and an LED light is mounted on the lower end of the mounting bracket.

[0010] Furthermore, the guiding assembly includes a guide roller one, which is rotatably mounted on the feed end of the frame. Two guide rollers two are arranged between the guide roller one and the winding mechanism. The two winding mechanisms are located below the outer casing. The guide roller one is rotatably connected to the frame. The polyester-cotton fabric passes over the guide roller one and under the guide rollers two.

[0011] Furthermore, the cleaning component includes a support plate, which is fixedly mounted on the frame and positioned between the outer casing and the guide roller. A scraper is mounted on the lower end of the support plate, and the scraper contacts the polyester-cotton cloth.

[0012] Furthermore, the cleaning assembly also includes a dust hood, which is fixedly mounted on the upper end of the support plate. The opening of the dust hood faces the contact position between the scraper and the polyester-cotton cloth, and the dust hood is connected to an external vacuum cleaner via a suction tube.

[0013] Furthermore, the winding mechanism includes a take-up roller, the two ends of which are rotatably connected to the frame via rotating shafts. The take-up roller and the rotating shafts are connected by fixing bolts. One of the rotating shafts has a second drive source at its power end, and the second drive source is mounted on the frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model utilizes an industrial camera paired with a sliding and adjustable detection structure and lighting components to achieve automated and accurate detection of defects in polyester-cotton fabrics. Compared to traditional manual visual inspection, it not only significantly reduces the high-intensity labor load of workers but also avoids the problems of missed or false detections of defects caused by subjective factors such as fatigue and experience differences during manual inspection. It improves detection efficiency and the accuracy of defect identification, makes up for the shortcomings of traditional inspection methods, and meets the actual needs of strict quality control of polyester-cotton fabrics in large-scale production in the textile industry.

[0015] 2. This utility model integrates a cleaning component and a guiding transmission structure. The scraper efficiently removes impurities adhering to the surface of the polyester-cotton fabric, and the dust collection hood promptly absorbs the generated dust, ensuring the cleanliness of the fabric surface and preventing impurities from affecting subsequent testing and roll quality. At the same time, the reasonable setting of the guide rollers ensures the stability of the fabric transmission process, reduces wrinkles and deviations, optimizes the overall process of polyester-cotton fabric production and processing, and improves production efficiency.

The cleaning component 5 also includes a dust suction hood 503, which is fixedly installed on the upper end of the support plate 501. The opening of the dust suction hood 503 faces the position where the scraper 502 contacts the polyester-cotton fabric.

[0023] See Figure 2 , Figure 3 , Figure 4As shown, the suction pipe 504 is made of PVC steel wire reinforced hose, and the suction hood 503 is connected to the external vacuum cleaner through the suction pipe 504. The detection component 2 includes a housing 201, which is fixedly installed on the frame 1. A cover plate 206 is installed on the upper end of the housing 201, and a transparent plate 207 is installed on the lower end of the housing 201. The transparent plate 207 is made of glass. A sliding plate 202 is slidably arranged on the inner side of the housing 201. Guides are provided between the two sides of the sliding plate 202 and the inner wall of the housing 201. The guides include guide rails 203, which are fixedly installed on the inner wall of the housing 201. A groove is provided on the sliding plate 202 at the corresponding position of the guide rail 203.

[0024] See Figure 4 , Figure 5 As shown, the guide rail 203 and the slide plate 202 are slidably arranged in a groove. The guide rail 203 is set in a "T" shape. A driving component is provided between the slide plate 202 and the housing 201. The driving component includes a lead screw 204, which is a ball screw. The lead screw 204 is rotatably mounted on the housing 201. The lead screw 204 is threadedly connected to the slide plate 202. One end of the lead screw 204 passes through the housing 201 and the frame 1. The power end of the lead screw 204 is provided with a drive source 205. The drive source 205 is a stepper motor, model 57HS22, with a step angle of 1.8°, and is equipped with a microstepping driver.

[0025] See Figure 4 , Figure 5 As shown, the drive source 205 is mounted on the frame 1. Lighting components 210 are mounted on both sides of the housing 201. The lighting components 210 include a mounting bracket 211, which is fixedly mounted on the housing 201. An LED light 212 is mounted on the lower end of the mounting bracket 211. The LED light 212 is a high color rendering index surface mount LED. An industrial camera 208 is mounted on the lower end of the slide plate 202. The industrial camera 208 is a CCD area array camera, model MV-CA050-10GM.

[0026] Regularly clean the scraper 502, dust hood 503, and industrial camera 208 lens; lubricate transmission components such as the rotating shaft 302 and lead screw 204; check the brightness and stability of LED 212 and replace damaged LED beads; test the alarm and data storage functions of the PLC control system. Disassemble the cleaning assembly 5 and thoroughly clean the residual impurities inside the dust suction pipe 504; check the shooting accuracy of the industrial camera 208.

[0027] The implementation principle is as follows: The operator leads out one end of the polyester-cotton fabric raw material to be tested, passes it through the top of the guide roller 1 401 in sequence according to the preset path, then passes it around the bottom of the two guide rollers 2 402, and finally fixes it on the take-up roller 301; at this time, the scraper 502 in the cleaning component 5 is in close contact with the surface of the polyester-cotton fabric; the external vacuum cleaner and the equipment drive system are started, and the polyester-cotton fabric begins to be smoothly transported under the traction of the roll mechanism 3; during the transport process, the scraper 502 continuously scrapes off the cotton lint, dust, fiber debris and other impurities attached to the surface of the polyester-cotton fabric. At the same time, the external vacuum cleaner generates negative pressure through the dust hood 503 to timely absorb and discharge the impurities scraped off by the scraper 502. When the cleaned polyester-cotton fabric is conveyed to the area below the housing 201, the lighting unit 210 and the industrial camera 208 are activated. The LED light 212 emits uniform light to illuminate the surface of the polyester-cotton fabric, eliminating shadows in the detection area and providing a clear shooting environment for the industrial camera 208. At the same time, the drive source 205 is activated and drives the lead screw 204 to rotate. The rotation of the lead screw 204 is converted into the reciprocating linear motion of the slide plate 202 along the guide rail 203. The industrial camera 208 at the lower end of the slide plate 202 moves synchronously with the slide plate 202 to collect comprehensive and blind-spot-free images of the polyester-cotton fabric conveyed below. The collected fabric images are transmitted in real time to the equipment control system for analysis and processing. Through image recognition algorithms, defects such as holes, skipped stitches, stains, and uneven yarn on the surface of the polyester-cotton fabric are automatically identified, and the location and type of defects are marked, realizing automated and accurate defect detection. The inspected polyester-cotton fabric continues to be transferred to the rolling mechanism 3. The drive source 303 drives the take-up roller 301 to rotate through the rotating shaft 302. The take-up roller 301 rotates at a uniform speed, neatly rolling up the inspected polyester-cotton fabric to form a standardized finished roll. If the control system detects defects during the inspection process, it can issue an alarm signal according to the preset program to remind the operator to handle it in time, or automatically record the location of the defect for subsequent sorting, so as to realize the collaborative operation of inspection and rolling.
