Description

Technical Field

[0001] This invention relates to the field of chemical fiber fabric technology, and in particular to a device for detecting the smoothness of chemical fiber fabrics. Background Technology

[0002] Polyester fabrics, a type of synthetic fiber fabric, are widely used in clothing and home furnishings. In particular, polyester fabrics that have undergone different textile treatments, such as crepe and napped fabrics, may have a certain degree of roughness and irregularity on their surface. The surface smoothness of these fabrics directly affects their appearance, feel, and service life. Therefore, it is necessary to use laser instruments to measure surface details to provide data support for quality control and product optimization.

[0003] Fleece, velvet, and coral fleece, produced through specific napping processes, are soft, comfortable, and fluffy, making them suitable for clothing and home furnishings where warmth is a high requirement.

[0004] Synthetic fiber fabrics have strong thermoplasticity. If the shaping is not sufficient during production, uneven shrinkage due to subsequent temperature changes will lead to a decrease in smoothness. Summary of the Invention

[0012] Preferably, the support assembly includes two undulating tracks symmetrically distributed and fixedly connected to the outer wall of the mounting frame. An oil tank is fixedly connected to the bottom of the transparent base. Roller slides are symmetrically slidably connected to the inner wall of the oil tank. The outer walls of the roller slides on the same side are slidably connected to the inner walls of the undulating tracks. A piston plate is fixedly connected to the top of the two roller slides. The outer wall of the piston plate is slidably connected to the inner wall of the oil tank. Springs are sleeved on the outer walls of the two roller slides. The outer walls of the two springs are fixedly connected to the inner walls of the oil tank. The outer walls of the two springs are fixedly connected to the bottom of the piston plate.

[0015] Preferably, the limiting assembly includes a limiting shell fixedly connected to the outer wall of the rubber rod, the bottom of the limiting shell being slidably connected to the top of the transparent base, a placement platform fixedly connected to the inner wall of the limiting shell, a rubber plate 1 slidably connected to the inner wall of the limiting shell, a rotating plate screw 1 threadedly connected to the inner wall of the limiting shell, the bottom of the rotating plate screw 1 being rotatably connected to the top of the rubber plate 1, a rubber plate 2 slidably connected to the inner wall of the limiting shell, a rotating plate screw 2 threadedly connected to the inner wall of the limiting shell, and the outer wall of the rubber plate 2 being rotatably connected to the outer wall of the rotating plate screw 2.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by the present invention compared with the prior art are as follows:

[0018] This invention features two scanning instruments and two heating components. The two scanning instruments detect the smoothness of the untreated pile fabric and acquire relevant data. The two heating components heat the pile fabric, while the two scanning instruments simultaneously detect the smoothness of the heated pile fabric and acquire relevant data. By comparing the two sets of data, the shrinkage rate of the pile fabric under heat can be obtained. This provides a theoretical basis for predicting and supporting the prevention of uneven shrinkage caused by subsequent temperature changes in synthetic fiber fabrics due to insufficient shaping during production, which can lead to a decrease in smoothness.

[0019] The present invention uses two scanning instruments. During the process of detecting the smoothness of the napped fabric, one instrument is positioned above and the other is positioned below. The two scanning instruments detect the smoothness of the napped fabric simultaneously, and then the smoothness data obtained by the two scanning instruments are compared, which helps to improve the accuracy of the final obtained smoothness detection data of the napped fabric.

[0020] The circular roller and reciprocating lead screw configured in this invention allow the circular roller to move back and forth when two scanning instruments are simultaneously detecting the smoothness of the napped fabric. This helps to separate the nap of the napped fabric, which may affect the reflection of the laser of the scanning instrument during measurement, resulting in inaccurate measurement results and making the measurement data obtained by the scanning instrument unable to reflect the true smoothness of the fabric.

[0021] The invention incorporates several holes (II) to allow hot air entering the roller to dissipate. Furthermore, the shape of these holes prevents lint from easily entering the roller through them when it reciprocates to part the nap of the fabric, reducing the risk of lint accumulation inside. Simultaneously, the dissipation of hot air through the holes helps to disperse any fine lint that does enter, preventing it from accumulating on the roller surface or within the holes and contributing to maintaining the roller's optimal working condition.

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0040] Example 1, as Figures 1-8 As shown, the device includes a mounting frame 1, a drive mechanism 2 on the inner wall of the mounting frame 1, hydraulic cylinders 3 symmetrically fixedly connected to the top of the mounting frame 1, and a prying mechanism 4 on the outer walls of the two hydraulic cylinders 3. The prying mechanism 4 includes a housing 41 fixedly connected to the outer walls of the two hydraulic cylinders 3, a motor 42 fixedly connected to the outer wall of the housing 41, a reciprocating screw 43 rotatably connected to the inner wall of the housing 41, the outer wall of the reciprocating screw 43 fixedly connected to the output end of the motor 42, round rods 44 symmetrically fixedly connected to the inner wall of the housing 41, a bracket 45 threadedly connected to the outer wall of the reciprocating screw 43, the inner wall of the bracket 45 slidably connected to the outer walls of the two round rods 44, a round roller 47 rotatably connected to the inner wall of the bracket 45, heating components 48 symmetrically arranged on the top of the bracket 45, and a scanning device 5 fixedly connected to the outer wall of the mounting frame 1 and the top of the housing 41.

[0041] The disengaging mechanism 4 also includes two racks 410 that are symmetrically distributed and fixedly connected to the inner wall of the outer shell 41. A rotating shaft 46 is fixedly connected to the inner wall of the roller 47. The outer wall of the rotating shaft 46 is rotatably connected to the inner wall of the bracket 45. Gears 49 are symmetrically fixedly connected to the outer wall of the rotating shaft 46. The outer wall of the gears 49 on the same side is meshed with the outer wall of the racks 410.

[0042] 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 484 fixedly connected to the outer wall of the rotating rod 483, a rack 485 fixedly connected to the inner wall of the outer shell 41, the outer wall of the rack 485 meshing with the outer wall of the gear 484, an air intake 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, and several holes 489 and several holes 4810 opened on the outer wall of the roller 47.

[0043] The heating assembly 48 also includes several air guide baffles 4811 fixedly connected to the outer wall of the rotating shaft 46, and the outer walls of the several air guide baffles 4811 are fixedly connected to the inner wall of the roller 47.

[0044] The aforementioned bracket 45 and the reciprocating lead screw 43 constitute a reciprocating lead screw structure in the prior art, which is a mature technical means in the prior art. The mechanism and working principle of this solution will not be elaborated further here.

[0045] The aforementioned bracket 45 is composed of a sliding plate and two symmetrically distributed connecting plates. Both connecting plates are fixedly connected to the sliding plate with bolts, so that the angle of the roller 47 installed on the two connecting plates can be adjusted as needed. Thus, in this invention, the roller 47 can move back and forth in an inclined manner.

[0046] Both of the aforementioned scanning instruments 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 borrows their function of detecting the surface flatness of chemical fiber fabrics. In specific use, they need to be used with an adjustable support arm structure. This support arm structure is composed of a support arm frame, an angle adjustment mechanism, and a precision positioning system. These are all mature technologies in the existing technology. This solution will not elaborate on their structure and working principle here.

[0047] The heating plate 482 mentioned above is a mature technology in the prior art. This solution only borrows its function of converting electrical energy into heat energy and setting the heating temperature. Its structure and working principle will not be elaborated further.

[0048] In a specific implementation of this invention, the device is placed at a suitable position for testing the flatness of chemical fiber fabrics. The napped fabric in the chemical fiber fabric is fixed in the drive mechanism 2. The drive mechanism 2 is turned on to move the napped fabric toward the spreading mechanism 4. After moving to a suitable position below the roller 47, the two hydraulic cylinders 3 are turned on to move the spreading mechanism 4 downward until the roller 47 contacts the nap of the napped fabric and is at a suitable contact distance. The two hydraulic cylinders 3 can adjust the distance between the roller 47 and the napped fabric so that the distance between the roller 47 and the napped fabric can be precisely controlled. This ensures that the roller 47 can effectively spread the nap without damaging the napped fabric due to excessive contact.

[0049] The motor 42 is turned on, which drives the reciprocating screw 43 to rotate, thereby driving the bracket 45 to move back and forth, which in turn drives the circular roller 47 to move back and forth, continuously brushing away the nap of the napped fabric. This helps to prevent the nap of the napped fabric from affecting the reflection of the laser of the scanning instrument 5 during measurement, which would lead to inaccurate measurement results and make the measurement data obtained by the scanning instrument 5 unable to reflect the true flatness of the fabric.

[0050] During this process, two scanning devices 5 are activated. The laser emitters in the two scanning devices 5 emit a laser beam that illuminates the surface and bottom of the fabric. The laser beam is reflected by the surface and bottom of the fabric, and the reflected light is received by the detector. The detector calculates the angle and intensity of the reflected light. Based on the angle and intensity of the reflected light, the instrument can calculate the surface morphology and obtain the height information at the corresponding position. Based on the obtained height information, a contour map of the fabric surface is drawn. These height data reflect the changes in the smoothness of the fabric, especially the true surface morphology after removing the interference of fuzz. This provides accurate data support for the detection of the smoothness of the fabric after the fuzz removal process. During the specific detection process, the angle of the support arm structure of the scanning device 5 can be adjusted to adjust the detection angle of the scanning device 5 so that the scanning device 5 can fully scan the surface and bottom of the fuzzy fabric.

[0051] As the circular roller 47 reciprocates to part the nap of the napped fabric, it drives the rotating shaft 46 to reciprocate, which in turn drives the two gears 49 to reciprocate and mesh with the rack 410 on the same side, causing the two gears 49 to rotate. This, in turn, drives the rotating shaft 46 to rotate, which in turn causes the circular roller 47 to rotate stably as it reciprocates to part the nap of the napped fabric. The continuous rotation of the circular roller 47 increases the additional power to the nap, which helps to more effectively part the surface nap and ensure that the nap is parted more evenly. This allows the scanning device 5 to obtain more stable and uniform surface reflection data, thereby improving the accuracy of flatness detection.

[0052] During the above process, it is not necessary to power on the two heating plates 482 so that the two scanning instruments 5 can detect the flatness of the unheated napped fabric and obtain relevant data.

[0053] When the two scanning instruments 5 are inspecting the flatness of the napped fabric, one is positioned above the napped fabric to inspect its flatness, and the other is positioned below the napped fabric to inspect its flatness. The inspection is carried out simultaneously from top to bottom. Then, the final flatness inspection data of the napped fabric is obtained by comparing the flatness inspection data from the top and bottom. This helps to improve the accuracy of the flatness inspection data of the napped fabric.

[0054] After completing the above operations, both heating plates 482 are powered on and set to a suitable temperature. The bracket 45 moves back and forth, driving both gears 484 to move back and forth, thus meshing with the rack 485 on the same side. This causes both gears 484 to rotate, driving both rotating rods 483 to rotate, which in turn drives both intake fan blades 486 to rotate, drawing external air into the two intake cylinders 481. The two heating plates 482 heat the air in the two intake cylinders 481 into hot air. The two intake fan blades 486 rotate and blow the hot air into the bracket 45 through the two ventilation hoses 487.

[0055] The rotation of the shaft 46 will drive the two negative pressure fan blades 488 to rotate, which will cause the hot air entering the bracket 45 to be rolled and blown into the roller 47 through several holes 1 489, and then blown out through several holes 2 onto the napped fabric to heat the napped fabric. At this time, two scanning instruments 5 will detect the flatness of the heated napped fabric and obtain relevant data.

[0056] The subsequent comparison of the smoothness test data of the heat-treated napped fabric with the smoothness test data of the non-heat-treated napped fabric will obtain the shrinkage rate of the napped fabric when heated. This will help prevent the problem of uneven shrinkage caused by subsequent temperature changes in the relatively strong thermoplasticity of chemical fiber fabrics if the shaping is not sufficient during production, which will lead to a decrease in smoothness. By detecting the shrinkage rate of chemical fiber fabrics when heated in advance, we can provide data and theoretical support for the prediction and solution of this problem.

[0057] The number and position of several air guide baffles 4811 installed in the circular roller 47 correspond one-to-one with the number and position of several holes 489. When both negative pressure fan blades 488 rotate and blow hot air into the circular roller 47 from the bracket 45, the hot air entering the circular roller 47 through the holes 489 will enter the space formed by the air guide baffles 4811 and the circular roller 47 respectively. At the same time, the hot air entering the circular roller 47 will rise upward, which is conducive to the diffusion of hot air to the inner wall of the circular roller 47, reducing the path and time for hot air to leave the circular roller 47, and improving the utilization efficiency of hot air.

[0058] The opening of several holes 4810 allows the hot air entering the roller 47 to dissipate. At the same time, the shape of the opening of several holes 4810 makes it difficult for the pile of the fabric to directly enter the roller 47 through several holes 4810 when the roller 47 moves back and forth to part the pile, reducing the risk of pile accumulating inside the roller 47. At the same time, the hot air can be dissipated through several holes 4810, which can blow away the fine pile that has entered the holes 4810, helping to expel the fine pile from the holes 4810 and preventing them from accumulating on the surface of the roller 47 or inside the holes 4810, thus helping to maintain the good working condition of the roller 47.

[0059] Meanwhile, during the reciprocating rotation of the circular roller 47, as it continues to rotate, regardless of how it rotates, several holes 4810 will always be rotated to a position where the air outlet faces the front of the moving direction of the circular roller 47, thereby blowing on the pile fabric in front of the moving direction of the circular roller 47 and helping to heat the pile fabric.

[0060] Example 2, as Figures 9-16As shown, the drive mechanism 2 includes a motor 21 fixedly connected to the outer wall of the mounting frame 1, threaded rods 22 symmetrically rotatably connected to the inner wall of the mounting frame 1, the output end of the motor 21 fixedly connected to the outer wall of one side of the threaded rod 22, a pulley group 23 fixedly connected to the outer walls of the two threaded rods 22, a transparent base 24 threadedly connected to the outer walls of the two threaded rods 22, the outer wall of the transparent base 24 slidably connected to the inner wall of the mounting frame 1, limit components 25 symmetrically provided on the top of the transparent base 24, support components 26 provided on the bottom of the transparent base 24, and damping components 27 symmetrically provided on the bottom of the transparent base 24.

[0061] Support assembly 26 includes two undulating tracks 261 symmetrically distributed and fixedly connected to the outer wall of mounting frame 1. An oil tank 262 is fixedly connected to the bottom of transparent base 24. Roller slide rods 265 are symmetrically slidably connected to the inner wall of oil tank 262. The outer wall of the roller slide rods 265 on the same side is slidably connected to the inner wall of the undulating track 261. A piston plate 263 is fixedly connected to the top of both roller slide rods 265. The outer wall of the piston plate 263 is slidably connected to the inner wall of oil tank 262. The outer walls of the two roller slide rods 265 are... Each spring 264 is fitted on its outer wall. 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. The inner wall of the hydraulic cylinder 266 is slidably connected to a spring piston rod 268. The top of the spring piston rod 268 is fixedly connected to a transparent plate 269.

[0062] The support assembly 26 also includes four telescopic rods 2610 that are fixedly connected to the bottom of the transparent plate 269 in a rectangular array, and the bottom of the four telescopic rods 2610 are fixedly connected to the top of the transparent base 24.

[0063] The damping assembly 27 includes a cylinder 271 fixedly connected to the bottom of the transparent base 24, and a rubber rod 272 slidably connected to the inner wall of the cylinder 271;

[0064] The limiting assembly 25 includes a limiting shell 251 fixedly connected to the outer wall of the rubber rod 272. The bottom of the limiting shell 251 is slidably connected to the top of the transparent base 24. A placement platform 252 is fixedly connected to the inner wall of the limiting shell 251. A rubber plate 253 is slidably connected to the inner wall of the limiting shell 251. A rotating screw 254 is threadedly connected to the inner wall of the limiting shell 251. The bottom of the rotating screw 254 is rotatably connected to the top of the rubber plate 253. A rubber plate 255 is slidably connected to the inner wall of the limiting shell 251. A rotating screw 256 is threadedly connected to the inner wall of the limiting shell 251. The outer wall of the rubber plate 255 is rotatably connected to the outer wall of the rotating screw 256.

[0065] The inner wall of the limiting housing 251 is symmetrically threaded with rotating plate screws 3 258. Rubber plates 3 257 are fixedly connected to the outer walls of the two rotating plate screws 3 258. The outer walls of the two rubber plates 3 257 are slidably connected to the inner wall of the limiting housing 251.

[0066] The aforementioned motor 21 and the two motors 42 are all servo motors, which are mature technologies in the existing technology. This solution only borrows their function of controlling the rotation speed, number of rotations and start / stop at any time, and will not elaborate on their structure and working principle.

[0067] The aforementioned 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 is fixedly connected to the inner wall of the hydraulic cylinder 266 and the outer wall of the piston rod body respectively;

[0068] Both the transparent plate 269 and the transparent base 24 are made of materials that will not affect the propagation of the laser of the scanning device 5;

[0069] In a specific implementation of the present invention, in the initial state, the two roller slides 265 are respectively located in the lower position of the two undulating tracks 261. At this time, the two roller slides 265 will not cause the piston plate 263 to move due to compression, thereby causing compression of the hydraulic oil in the oil tank 262.

[0070] Lay out the napped fabric that needs to be tested for flatness, and place one side of the fabric flat on the placement platform 252, so that the fabric covers the top of the placement platform 252, the side wall of the placement platform 252 opposite the second rubber plate 255, and the two side walls of the placement platform 252 opposite the two third rubber plates 257. Rotate the first rotating screw 254 to move the first rubber plate 253 towards the placement platform 252 until the napped fabric is firmly pressed on the placement platform 252. Rotate the second rotating screw 256 to move the second rubber plate 255 towards the placement platform 252 until the napped fabric on the side wall of the placement platform 252 is firmly fixed. Rotate the two third rotating screws 258 to move the two third rubber plates 257 towards the placement platform 252 until the napped fabric on the side wall of the placement platform 252 is firmly fixed, thereby preventing the napped fabric from moving randomly during the subsequent flatness test and affecting the normal progress of the flatness test.

[0071] Using the above method, the other side of the pile fabric is fixed in place by the limiting component 25 on the other side in the same way. At this time, the pile fabric is in contact with the transparent plate 269, and the side to be tested is facing upward.

[0072] The two limiting shells 251 can slide to adjust the distance between them, making it more convenient and flexible to fix the pile fabric using the two limiting components 25. When the two limiting shells 251 slide, they drive the two rubber rods 272 to slide inside the two cylinders 271 respectively. The two rubber rods 272 play a role in increasing friction, so that the two limiting shells 251 with adjusted positions will not slide randomly under the action of external force, thus affecting the state of the pile fabric.

[0073] When the motor 21 is turned on, the threaded rod 22 rotates. Under the action of the pulley group 23, both threaded rods 22 rotate, thereby driving the transparent base 24 to move towards the disengaging mechanism 4. This causes both roller slides 265 to move towards the disengaging mechanism 4. Before moving to the appropriate position of the roller 47, the two roller slides 265 move from the lower position in the two undulating tracks 261 to the higher position, thereby causing both roller slides 265 to be squeezed. This causes 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. The hydraulic oil is then squeezed into the position between the hydraulic cylinder 266 and the spring piston rod 268 through the oil hose 267.

[0074] The hydraulic oil entering between the hydraulic cylinder 266 and the spring piston rod 268 will squeeze the spring piston rod 268, thereby causing the spring piston rod 268 to move upward a certain distance, thus contacting the napped fabric. When the subsequent spreading mechanism 4 processes the napped fabric, it will support the napped fabric.

[0075] Turn on motor 21 to drive threaded rod 22 to rotate, causing transparent base 24 to continue moving towards disengagement mechanism 4, thereby driving pile fabric to continue moving towards disengagement mechanism 4 until it moves to a suitable position below disengagement mechanism 4. Turn off motor 21. After completing the flatness detection of pile fabric using disengagement mechanism 4 and two scanning instruments 5 according to the above operation, turn off disengagement mechanism 4 and two scanning instruments 5, and remove pile fabric from two limiting components 25.

[0076] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
