[0002] Polyester fabrics among chemical fiber fabrics are widely used in clothing and household items. In particular, polyester fabrics that have undergone different textile treatments, such as crepe and pile, may have certain surface roughness and irregularities.

A rotating shaft 46 is fixedly connected to the inner wall of the circular roller 47. The outer wall of the rotating shaft 46 is rotatably connected to the inner wall of the bracket 45. A second gear 49 is symmetrically fixedly connected to the outer wall of the rotating shaft 46. The outer wall of the second gear 49 on the same side is meshed with the outer wall of the second rack 410. The heating assembly 48 includes an air inlet cylinder 481 fixedly connected to the top of the bracket 45, a heating plate 482 fixedly connected to the outer wall of the air inlet cylinder 481, a rotating rod 483 rotatably connected to the inner wall of the air inlet cylinder 481, a gear 1 484 fixedly connected to the outer wall of the rotating rod 483, a rack 1 485 fixedly connected to the inner wall of the housing 1 41, the outer wall of the rack 1 485 meshes with the outer wall of the gear 1 484, an air inlet fan blade 486 fixedly connected to the outer wall of the rotating rod 483, a ventilation hose 487 fixedly connected to the inner wall of the bracket 45, a negative pressure fan blade 488 fixedly connected to the outer wall of the rotating shaft 46, a plurality of holes 1 489 opened on the outer wall of the circular roller 47, and a plurality of holes 2 4810 opened on the outer wall of the circular roller 47; The heating assembly 48 further includes a plurality of air guide baffles 4811 fixedly connected to the outer wall of the rotating shaft 46 , and the outer walls of the plurality of air guide baffles 4811 are fixedly connected to the inner wall of the round roller 47 .

[0024] The bracket 45 and the reciprocating screw 43 constitute a reciprocating screw structure in the prior art, which is a mature technical means in the prior art. This solution will not elaborate on its structure and working principle. The bracket 45 is composed of a sliding plate and two symmetrically distributed connecting plates. The two connecting plates are fixedly connected to the sliding plate by bolts, so that the angle of the round roller 47 mounted on the two connecting plates can be adjusted as needed. In this way, the round roller 47 of the present invention can reciprocate in an inclined state. The two scanning devices 5 are composed of a laser emitter, an optical system, a detector, a data acquisition, display and control system, and a processing unit. This solution only uses them to complete the function of detecting the surface flatness of chemical fiber fabrics. In specific use, they need to be equipped with an angle-adjustable support arm structure. This support arm structure consists of an arm frame, an angle adjustment mechanism, and a precision positioning system. They are all mature technical means in the prior art, and this solution will not elaborate on their structure and working principle. The heating plate 482 is a mature technical means in the prior art. This solution only uses its function of converting electrical energy into thermal energy and setting the heating temperature. Its structure and working principle will not be elaborated further. In the specific implementation of the present invention, the device is placed at a suitable position for detecting the flatness of chemical fiber fabrics, the pile fabric in the chemical fiber fabric is fixed in the driving mechanism 2, the driving mechanism 2 is turned on to drive the pile fabric to move in the direction of the spreading mechanism 4, and after moving to a suitable position below the round roller 47, the two hydraulic cylinders 3 are turned on to drive the spreading mechanism 4 to move downward until the round roller 47 contacts the pile of the pile fabric and is at a suitable contact distance from the pile fabric. The two hydraulic cylinders 3 can adjust the distance between the round roller 47 and the pile fabric, so that the distance between the round roller 47 and the pile fabric can be precisely controlled, ensuring that the round roller 47 can complete the task of effectively spreading the pile without damaging the state of the pile fabric due to too close contact with the pile fabric. Turn on the second motor 42 to drive the reciprocating screw 43 to rotate, thereby driving the bracket 45 to move back and forth, thereby driving the round roller 47 to move back and forth, and continuously pushing away the pile of the pile fabric, which is beneficial to prevent the pile of the pile fabric from affecting the reflection of the laser of the scanning device 5 during measurement, resulting in inaccurate measurement results, so that the measurement data obtained by the scanning device 5 cannot reflect the true flatness of the fabric; During this process, two scanning instruments 5 are turned on, and the laser transmitters in the two scanning instruments 5 emit a beam of laser light to illuminate the surface and bottom surface of the fabric. The laser beam is reflected by the surface and bottom surface of the fabric, and the reflected light is received by the detector, and the angle and intensity of the reflected light are calculated. According to the angle and intensity of the reflected light, the instrument can calculate the surface morphology and obtain the height information of the corresponding position. According to the obtained height information, a contour map of the fabric surface is drawn. These height data reflect the change in the flatness of the fabric, especially the real surface morphology after removing the interference of the fluff, and provide accurate data support for the detection of the flatness of the fabric after the plucking process. In the specific detection process, the support arm structure angle of the scanning instrument 5 can be adjusted, and the detection angle of the scanning instrument 5 can be adjusted so that the scanning instrument 5 can fully scan the surface and bottom surface of the pile fabric. When the circular roller 47 moves back and forth to push away the fluff of the fleece fabric, it drives the rotating shaft 46 to move back and forth, thereby driving the two gears 49 to move back and forth, respectively meshing with the rack 410 on the same side, so that the two gears 49 rotate, thereby driving the rotating shaft 46 to rotate, thereby driving the circular roller 47 to rotate stably when moving back and forth to push away the fluff of the fleece fabric. The continuous rotation of the circular roller 47 increases the additional power to the fluff, which helps to more effectively push away the surface fluff and ensure that the fluff is pushed away more evenly, so that the scanning device 5 can obtain more stable and uniform surface reflection data, thereby improving the accuracy of flatness detection; In the above process, it is not necessary to power on the two heating plates 482 , and the two scanning devices 5 are allowed to detect the flatness of the pile fabric that has not been heated and obtain relevant data; When the two scanning devices 5 detect the flatness of the pile fabric, one is located above the pile fabric to detect its flatness, and the other is located below the pile fabric to detect its flatness, and the upper and lower parts are detected synchronously. Then, the final pile fabric flatness detection data is obtained by comparing the upper and lower flatness detection data, which is conducive to improving the accuracy of the pile fabric flatness detection data; After completing the above operations, both heating plates 482 are powered on and set to a suitable temperature. The bracket 45 reciprocates, driving the two gears 484 to reciprocate, thereby engaging with the rack 485 on the same side, causing the two gears 484 to rotate, driving the two rotating rods 483 to rotate, thereby driving the two air intake blades 486 to rotate, and drawing the external air into the two air intake cylinders 481 respectively. The two heating plates 482 will heat the air in the two air intake cylinders 481 into hot air respectively. The two air intake blades 486 rotate and blow the hot air into the bracket 45 through the two ventilation hoses 487 respectively. The rotation of the rotating shaft 46 drives the two negative pressure fan blades 488 to rotate, rolling the hot air entering the bracket 45 and blowing it into the round roller 47 through the plurality of holes 1 489, and then further out through the plurality of holes 2 to blow on the pile fabric, thereby heating the pile fabric. At this time, the two scanning devices 5 detect the flatness of the heated pile fabric and obtain relevant data. Subsequently, the obtained flatness test data of the pile fabric that has been heated will be compared with the flatness test data of the pile fabric that has not been heated to obtain the shrinkage rate of the pile fabric when heated. This is helpful to prevent the problem of uneven shrinkage due to subsequent temperature changes and loss of flatness caused by the strong thermoplasticity of chemical fiber fabrics if the shaping is not sufficient during production. By testing the shrinkage rate of chemical fiber fabrics when heated in advance, we can provide data theoretical support for the predictive solution of this problem. The number and positions of the air guide baffles 4811 installed in the roller 47 correspond to the number and positions of the holes 489. When the two negative pressure blades 488 rotate to blow the hot air entering the bracket 45 into the roller 47, the hot air entering the roller 47 through the holes 489 will enter the spaces formed by the air guide baffles 4811 and the roller 47. At the same time, the hot air entering the roller 47 will rise upward, which is conducive to the diffusion of the hot air to the inner wall of the roller 47, reducing the path and time for the hot air to exit the roller 47, and improving the utilization efficiency of the hot air. The opening of the plurality of holes 4810 allows the hot air that enters the round roller 47 to be dissipated. At the same time, the opening shape of the plurality of holes 4810 makes it difficult for the fluff of the pile fabric to be directly entered into the round roller 47 through the plurality of holes 4810 when the round roller 47 moves back and forth to separate the fluff, thereby reducing the risk of the fluff accumulating inside the round roller 47. At the same time, the hot air is dissipated through the plurality of holes 4810, which can blow the fine fluff that enters the plurality of holes 4810, helping the fine fluff in the plurality of holes 4810 to be discharged, avoiding their accumulation on the surface of the round roller 47 or in the plurality of holes 4810, and helping to keep the round roller 47 in good working condition. At the same time, during the reciprocating rotation of the circular roller 47, while maintaining the rotation state, no matter how it rotates, there will always be a number of holes 4810 that will be rotated to a state where the air outlet is facing the front of the moving direction of the circular roller 47, thereby blowing the pile fabric in front of the moving direction of the circular roller 47 to help heat the pile fabric.

The outer walls of the two springs 264 are fixedly connected to the inner wall of the oil tank 262. The outer walls of the two springs 264 are fixedly connected to the bottom of the piston plate 263. The inner wall of the transparent base 24 and the top of the oil tank 262 are fixedly connected to a hydraulic cylinder 266. The outer wall of the hydraulic cylinder 266 and the top of the oil tank 262 are connected through an oil hose 267. A spring piston rod 268 is slidably connected to the inner wall of the hydraulic cylinder 266. The top of the spring piston rod 268 is fixedly connected to a transparent plate 269. The support assembly 26 further includes four telescopic rods 2610 distributed in a rectangular array and fixedly connected to the bottom of the transparent plate 269. The bottoms of the four telescopic rods 2610 are fixedly connected to the top of the transparent base 24. The damping assembly 27 includes a cylinder 271 fixedly connected to the bottom of the transparent base 24, and a rubber rod 272 is slidably connected to the inner wall of the cylinder 271; The limiting assembly 25 includes a limiting housing 251 fixedly connected to the outer wall of the rubber rod 272, the bottom of the limiting housing 251 is slidably connected to the top of the transparent base 24, the inner wall of the limiting housing 251 is fixedly connected to a placing platform 252, the inner wall of the limiting housing 251 is slidably connected to a rubber plate 1 253, the inner wall of the limiting housing 251 is threadedly connected to a rotating plate screw 1 254, the bottom of the rotating plate screw 1 254 is rotatably connected to the top of the rubber plate 1 253, the inner wall of the limiting housing 251 is slidably connected to a rubber plate 255, the inner wall of the limiting housing 251 is threadedly connected to a rotating plate screw 256, and the outer wall of the rubber plate 255 is rotatably connected to the outer wall of the rotating plate screw 256; The inner wall of the limiting shell 251 is symmetrically threaded with a rotating plate screw rod 3 258 , and the outer walls of the two rotating plate screw rods 258 are fixedly connected with a rubber plate 3 257 . The outer walls of the two rubber plates 3 257 are slidably connected to the inner wall of the limiting shell 251 .

[0026] The motor 1 21 and the two motors 2 42 are both servo motors, which are mature technical means in the prior art. This solution only uses the function of controlling the rotation speed, number of rotations and start and stop of the object at any time, and will not elaborate on its structure and working principle. The spring piston rod 268 is composed of a piston rod body and a spring, wherein the spring is sleeved on the outer wall of the piston rod body and fixedly connected to the inner wall of the hydraulic cylinder 266 and the outer wall of the piston rod body respectively; The transparent plate 269 and the transparent base 24 are both made of materials that will not affect the propagation of the laser beam of the scanning device 5; In the specific implementation of the present invention, in the initial state, the two roller slide bars 265 are respectively located at the lower position within the two undulating tracks 261. At this time, the two roller slide bars 265 will not be squeezed to drive the piston plate 263 to move, thereby squeezing the hydraulic oil in the oil tank 262. The two rotating plate screws 258 are rotated to drive the two rubber plates 257 to move toward the placement platform 252 until the fleece fabric on the side wall of the placement platform 252 is firmly fixed. The two rotating plate screws 258 are rotated to drive the two rubber plates 257 to move toward the placement platform 252 until the fleece fabric on the side wall of the placement platform 252 is firmly fixed, thereby preventing the fleece fabric from moving arbitrarily during the subsequent flatness test and affecting the normal progress of the flatness test. Use the above method to use the limiting component 25 on the other side to firmly fix the other side of the fleece fabric in the same way. At this time, the fleece fabric is in contact with the transparent plate 269, and the side to be tested is facing upwards. The two limiting shells 251 can slide to adjust the distance between them, making it more convenient and flexible to fix the fleece fabric using the two limiting components 25. When the two limiting shells 251 slide, they respectively drive the two rubber rods 272 to slide in the two cylinders 271. The two rubber rods 272 increase the friction force, so that the two adjusted limiting shells 251 will not slide arbitrarily under the action of external force, thereby affecting the state of the fleece fabric. The motor 1 21 is turned on to drive the threaded rod 22 to rotate. Under the action of the pulley group 23, the two threaded rods 22 are rotated, thereby driving the transparent base 24 to move toward the opening mechanism 4, thereby driving the two roller slides 265 to move toward the opening mechanism 4. Before moving to the appropriate position of the round roller 47, the two roller slides 265 are respectively moved from the lower position in the two undulating tracks 261 to the higher position, so that the two roller slides 265 are squeezed, thereby driving the piston plate 263 to slide upward a certain distance in the oil tank 262, squeezing the hydraulic oil between the piston plate 263 and the oil tank 262, and squeezing the hydraulic oil into the position between the hydraulic cylinder 266 and the spring piston rod 268 through the oil hose 267; The hydraulic oil entering between the hydraulic cylinder 266 and the spring piston rod 268 will squeeze the spring piston rod 268, thereby driving the spring piston rod 268 to move upward a certain distance, so as to contact the pile fabric, and play a supporting role for the pile fabric when the subsequent spreading mechanism 4 processes the pile fabric; Turn on motor 1 21 to drive the threaded rod 22 to rotate, so that the transparent base 24 continues to move toward the spreading mechanism 4, thereby driving the fleece fabric to continue to move toward the spreading mechanism 4 until it moves to a suitable position below the spreading mechanism 4. Turn off motor 1 21, and after completing the flatness inspection of the fleece fabric using the spreading mechanism 4 and the two scanning instruments 5 according to the above operation, turn off the spreading mechanism 4 and the two scanning instruments 5, and take the fleece fabric out of the two limiting components 25.
