Description

Technical Field

[0001] This utility model relates to the field of textile material testing technology, and in particular to an online detection device for the thickness and uniformity of suede-like materials. Background Technology

[0002] In the vast field of textiles and leather products today, imitation suede, with its soft texture, delicate feel, and appearance closely resembling natural suede, has been widely used in clothing, home décor, automotive interiors, and many other industries. As market demand for imitation suede products continues to grow, consumers' expectations for product quality are also increasing. Thickness and uniformity, as core quality characteristics of imitation suede, play a decisive role in the performance and aesthetics of the final product. To ensure the quality of imitation suede, an online detection device for its thickness and uniformity is needed.

[0013] In at least some embodiments,

[0019] This invention provides an online detection device for the thickness and uniformity of simulated suede, which has the following beneficial effects:

[0020] This invention employs a combination of an infrared rangefinder and a visual detector. The infrared rangefinder can accurately measure the thickness of the imitation suede, with its high-precision measurement capability down to the millimeter or even smaller level, ensuring the accuracy of thickness detection. The visual detector, on the other hand, can comprehensively scan the surface condition of the imitation suede and use image analysis technology to determine the uniformity of the thickness distribution. The two complement each other, enabling a comprehensive and detailed evaluation of the quality of the imitation suede, leaving no detail overlooked and effectively improving the overall quality level of the product.

[0021] Furthermore, in this invention, for example, a spring is fitted onto the bolt connecting the top seat and the support plate, which can automatically adjust the pressure of the top roller according to the different thicknesses and material characteristics of the imitation suede, adapting to the testing needs of various specifications and types of imitation suede. At the same time, the setting of components such as the track plate, sliding seat, and lead screw allows the infrared rangefinder to move flexibly within a certain range, enabling detailed testing of different positions of the imitation suede and meeting diverse testing requirements. Whether it is a large area of ​​imitation suede sheet material or a narrow width of imitation suede roll material, efficient and accurate testing can be performed.

[0022] Furthermore, this invention allows for an increase in the distance between the two sets of connecting cylinders by rotating the handwheel, facilitating the installation and removal of the receiving roller. In actual operation, when the receiving roller needs to be installed, the operator simply needs to easily rotate the handwheel. As the handwheel rotates, it drives the connected threaded rod to rotate. Because the threaded rod and the threaded hole on the movable plate are in a threaded fit relationship, and the movable plate's movement on the round rod between the two sets of No. 1 side plates is restricted, it can only move along the axial direction of the round rod. Driven by the threaded rod, the movable plate moves forward or backward along the round rod, thereby changing the position of the No. 1 support plate installed on the upper part of the movable plate and the No. 2 support plate installed on the upper part of the No. 2 side plate. The relative positions of the two pallets gradually increase the distance between the two sets of connecting cylinders. At this point, the receiving roller can be easily placed between the two sets of connecting cylinders. Then, the handwheel is rotated in the opposite direction to make the connecting cylinders fit tightly against both ends of the receiving roller, completing the installation of the receiving roller. Similarly, when it is necessary to disassemble the receiving roller, the handwheel is rotated again to increase the distance between the connecting cylinders, and the receiving roller can be easily removed. This simplifies the installation and disassembly process of the receiving roller, improves the efficiency of equipment maintenance and material replacement, reduces equipment downtime caused by inconvenient installation and disassembly, and further enhances the continuity and efficiency of the entire imitation suede production and testing process.

[0046] Example 2, based on Example 1,

[0047] A support frame 3 is provided on the right side of the fixed frame 1. A fixed plate 31 is fixed on the support frame 3. A vision detector 32 is installed on the fixed plate 31 by bolts. The vision detector 32 is a Hikvision MV-CA type. Its function is to perform a comprehensive scan of the surface condition of the imitation suede and determine the uniformity of the thickness distribution through image analysis technology.

[0048] Example 3, based on Examples 1 and 2,

[0049] A first plate 33 and a second plate 34 are fixed to the support frame 3. Two sets of first side plates 331 are fixed to the first plate 33. Two sets of round rods 332 are fixed between the two sets of first side plates 331. Movable plates 333 are movably mounted on the two sets of round rods 332. The movable plates 333 are provided with threaded holes. A threaded rod 336 is installed between the two sets of first side plates 331 through a bearing. The threaded rod 336 is threadedly engaged with the threaded holes on the movable plate 333. A handwheel 337 is fixed to the front end of the threaded rod 336. A first support plate 33 is bolted to the upper end of the movable plate 333. 4. Two sets of second side plates 341 are fixed on the second plate 34. Second support plates 342 are bolted to the upper ends of the two sets of second side plates 341. Connecting cylinders 335 are mounted to the upper ends of both the first support plate 334 and the second support plate 342 via bearings. A receiving roller 35 is installed between the two sets of connecting cylinders 335. A gearbox 343 is bolted to the second plate 34. The output shaft of the gearbox 343 is connected to the rear end of the connecting cylinders 335 on the second support plate 342. A third motor 344 is bolted to the gearbox 343. Its function is: when installation is required... When the receiving roller 35 is in operation, the operator only needs to easily turn the handwheel 337. As the handwheel 337 rotates, it drives the connected threaded rod 336 to rotate. Since the threaded rod 336 is threadedly engaged with the threaded hole on the movable plate 333, and the movable plate 333 is restricted in its movement on the round rod 332 between the two sets of first side plates 331, it can only move along the axial direction of the round rod 332. Driven by the threaded rod 336, the movable plate 333 moves forward or backward along the round rod 332, thereby changing the position of the first support plate 334 mounted on the upper end of the movable plate 333. The relative positions of the second support plate 342 mounted on the upper end of the second side plate 341 cause the distance between the two sets of connecting cylinders 335 to gradually increase. At this time, the take-up roller 35 can be conveniently placed between the two sets of connecting cylinders 335. Then, the handwheel 337 is rotated in the opposite direction to make the connecting cylinders 335 fit tightly against both ends of the take-up roller 35, thus completing the installation operation of the take-up roller 35. Similarly, when it is necessary to disassemble the take-up roller 35, the handwheel 337 is rotated again to increase the distance between the connecting cylinders 335, and the take-up roller 35 can be easily removed, simplifying the installation and disassembly process of the take-up roller 35.

[0050] The working principle of this embodiment is as follows: First, the imitation suede roll to be tested is installed on the feeding roller 12. Then, the imitation suede is pulled to pass through the bottom roller 131 and the top roller 133 in sequence. Since the bolts connecting the top seat 132 and the support plate 13 are fitted with springs, the top roller 133 can automatically adjust its position and apply appropriate pressure according to the thickness of the imitation suede to ensure that the imitation suede remains flat. When the imitation suede passes through the detection area, the first motor 233 located on the two sets of rail plates 23 is started, driving the lead screw 232 to rotate, so that the sliding seat 231 can move left and right on the rail plate 23. The movement adjusts the position of the connecting seat 234 and the base 235 below it. Simultaneously, the second motor 236 on the base 235 near the front end of the partition 14 starts, driving the movable seat 24 to move on the guide rod 237 via the pulley and transmission belt 2361. This allows the infrared rangefinder 241, mounted at the lower end of the movable seat 24, to accurately measure the thickness of the imitation suede at different locations. The infrared rangefinder 241 emits infrared signals, calculates the thickness data of the imitation suede based on the signal reflection time, and transmits this data to the control system. Furthermore, by extending four sets of... Hydraulic rod 21 presses four sets of pressing blocks 221 down onto the imitation suede, making it fit against the partition 14, which can reduce the error of the detection data. While performing thickness detection, the vision detector 32 on the right support frame 3 of the fixed frame 1 acquires images of the surface of the imitation suede. The vision detector 32 uses its high-precision image sensor to acquire image information of the surface of the imitation suede to determine whether there are areas of abnormal local thickness changes or excessive thickness differences in the imitation suede. After the detection is completed, the imitation suede continues to be transported through the movable plate 333, the first support plate 334, the second support plate 342, and the connecting plate. The receiving structure consisting of the connecting cylinders 335 performs winding. When the receiving roller 35 needs to be installed, the operator turns the handwheel 337, which drives the threaded rod 336 to rotate, causing the movable plate 333 to move on the round rod 332, changing the distance between the first support plate 334 and the second support plate 342 so that the receiving roller 35 can be placed between the two sets of connecting cylinders 335. Then, the handwheel 337 is turned in the opposite direction to make the connecting cylinders 335 clamp the receiving roller 35. During the winding process, the third motor 344 drives the gearbox 343, which in turn drives the connecting cylinders 335 to rotate, realizing the winding operation of the imitation suede.
