Existing textile fiber testing devices cannot effectively detect extra-long fibers such as flax, hemp, sisal, and hemp, which leads to changes in fiber shape and movement, making accurate detection and self-regulating impossible and increasing redundancy in subsequent processes.
The system uses pressure rollers to apply pressure to the fibers for detection. Sensors detect the movement of the pressure rollers and calculate the fiber thickness to prevent fiber deformation, thus achieving online real-time detection and self-adjusting uniformity.
Ensuring that fibers enter the combing box straight enables accurate detection of ultra-long fibers, improves sliver quality, and reduces production difficulty and resource waste.

Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of textile processing, and in particular to a textile fiber detection device, a detection method and a self-adjusting leveling control system. BACKGROUND
[0002] The self-adjusting leveling control system of the textile equipment refers to that the amount of the fed-in sliver rod is accurately detected and fed back to the control system to control the thickness of the sliver to achieve the purpose of self-adjusting leveling.
[0003] Some fibers cannot be destroyed and deformed in the movement process (such as linen spinning in the wet spinning process), so that the purpose of accurate detection can be achieved. Figure 1 As shown in the prior art self-adjusting leveling control system, the working platform 10 and the detection device 50, the feeding roller 20, the comb box 30 and the sliver roller 40 arranged in sequence on the working platform 10 are provided. The feeding roller 20 inputs the fiber to the comb box 30, the fiber is combed after the comb box 30, and then output from the sliver roller 40, and then the spinning process is carried out in the next station. Figure 2 As shown in the prior art detection device 50, the detection of the thickness of the fiber is realized by a pair of concave-convex rollers pressing each other, so that the fiber 7 will be subjected to double extrusion force while moving, and individual fibers cannot be extruded (such as linen fibers in the wet spinning process), so that the shape and movement state of the fiber 7 will be inevitably changed, so that the fiber 7 cannot be flatly input into the comb box, resulting in that the comb box cannot effectively comb the fiber 7, and the fed-in fiber 7 cannot be accurately detected.
[0004] In the traditional textile industry, the detection method and structure are determined by the characteristics of the target fiber, and the roller detection method is born, which evolves from mechanical roller to electronic roller, and improves the accuracy. However, due to the structural limitation, the double roller (including the fixed roller and the movable roller) cannot detect the textile raw materials with super-long fiber characteristics such as linen, hemp, sisal, fire hemp and ramie. Therefore, in the field of this kind of super-long fiber spinning, there is a lack of effective online detection method, which causes the problem of process redundancy such as weighing, multiple drafting and drawing in the later process. SUMMARY
[0005] The purpose of the present application is to provide a textile fiber detection device, a detection method and a self-adjusting leveling control system to improve the accurate detection of the fed-in fiber.

[0010] The application further provides a self-adjusting leveling control system comprising a working platform and, arranged on the working platform in sequence, a detection device, a feed roller, a comb box and a delivery roller, the detection device being the above-described textile fiber detection device.
[0011] The application further provides a fiber detection method, which is performed by using the above-described textile fiber detection device and comprises the following steps. The fiber is displaced along the Y direction on the base at a speed V1, the base and the moving mechanism and the pressing roller thereon are displaced along the Y direction at a speed V2, and simultaneously, the pressing roller is displaced along the X direction on the base at a speed V3, and in the displacement process, the pressing roller applies pressure to the fiber on the base surface, so that the pressing roller generates an up-and-down movement between the fibers, the sensor senses the movement and converts it into an electrical signal sent to the control system, and the control system calculates the thickness value of the fiber based on the electrical signal.
[0012] Preferably, the fiber is placed on the base, and the fiber is laid flat on the base along the X direction from A to B, wherein A is the starting point, and the pressure roller reciprocates between A and B; the base slides in the Y direction by a distance between C and B, wherein C is the starting point, and the base reciprocates between C and B; the sensor collects n thicknesses h during movement of the pressure roller from A to B, and the thickness value H1 of the fiber is h1+h2+…+hn; the pressure roller moves from A to B on the base for the first time, the sensor collects data H=h1+h2+h3+…+hn, and the data is set to zero, h1=0, h2=0, h3=0,…, hn=0, and the total value H=0.

For the sake of description, if the terms "upper", "lower", "left", "right" appear in the following text, they only mean the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.
[0021] As shown in Fig. 1, the textile fiber detection device provided by the present embodiment comprises a base 1, a movement mechanism 2, a compression roller 3, a sensor 4, a first track 5 and a first driving source 6. Figure 3 The base 1 is slidably arranged in the Y direction. The upper surface of the base 1 is provided with a base surface 11. The movement mechanism 2 is arranged on the base 1 and slidably arranged in the X direction. The compression roller 3 is arranged at the end of the movement mechanism 2, and the compression roller 3 is telescopic in the Z direction when the movement mechanism 2 slides, so as to apply pressure to the base surface 11. The sensor 4 is arranged on the compression roller 3 for sensing the movement value of the compression roller 3 in the Z direction, and converting it into an electrical signal and sending it to a control system. The control system is used to output the thickness value of the fiber by calculating the electrical signal. The first track 5 is arranged at the bottom of the base 1. The first driving source 6 is a motor for driving the base 1 to slide in the Y direction on the first track 5.
[0022]
[0023] The movement mechanism 2 comprises a frame 21, a second track 22, a sliding frame 23 and a second driving source 24, the second track 22 extends along the X direction, and the second track 22 is connected to the upper side of the base 1 through the frame 21, the sliding frame 23 is slidingly arranged on the second track 22, and the sliding frame 23 is connected to the end of the base plate 11. The second driving source 24 is a motor for driving the sliding frame 23 to slide on the second track 22. The sliding frame 23 comprises a sliding block 231, a mounting frame 232, a mounting seat 233 and a compression spring 234, the sliding block 231 is slidingly connected with the second track 22, the mounting frame 232 is connected with one end of the sliding block 231 in the Y direction, the mounting seat 233 is connected with the mounting frame 232 in the Z direction, the bottom of the mounting seat 233 is provided with the compression spring 234, and the bottom of the compression spring 234 is connected with the compression roller 3. The compression spring 234 can ensure that the compression roller 3 applies appropriate pressure and is pressed on the fiber 7.
[0024] As shown in Figure 1 The application also provides a self-adjusting leveling control system, which comprises a working platform 10 and detection devices 50, feed rollers 20, comb boxes 30 and delivery rollers 40 arranged in sequence on the working platform 10. The detection devices 50 are the above-mentioned textile fiber detection devices.
[0025] The application also provides a fiber detection method, which is performed by using the above-mentioned textile fiber detection device and comprises the following steps. Step S1, the compression roller 3 is corrected so that the thickness H value obtained when the compression roller 3 is displaced on the base plate 11 is 0. That is, the compression roller 3 is moved from point A to point B on the base plate 11 for the first time, the data H=h1+h2+h3+…+hn collected by the sensor 4 is set to zero h1=0, h2=0, h3=0,…, hn=0, and the total value H=0.
[0026] Step S2, the fiber 7 is placed on the base 1, and the fiber 7 is laid on the base 1 along the X direction from A to B, wherein A is the starting point.
[0027] Step S3, under the action of the feed roller 20, the fiber 7 is pulled to displace on the base 1 along the Y direction at a speed V1. The base 1 and the movement mechanism 2 and the compression roller 3 thereon are moved from A to B along the Y direction at a speed V2, and at the same time, the compression roller 3 is driven to displace on the base 1 along the X direction at a speed V3 under the action of the second driving source 24, and in the displacement process, the compression roller 3 applies pressure to the fiber 7 on the base plate 11, so that the compression roller 3 generates an up-and-down fluctuation amount when passing through the fiber 7. The sensor 4 senses the movement amount and converts it into an electric signal to send to the control system, and the control system outputs the thickness value (thickness value) of the fiber through calculation of the electric signal.
[0028] AsFigure 1 、 Figure 4 The first setting is that sensor 4 collects n thickness h values during the movement from A to B. The second setting is that sensor 4 collects n thickness h values during the movement from B to A. The first driving source 6 and the second driving source 24 are started to rotate forward, and the control system calculates the thickness value H1=h1+h2+…+hn of the fiber detected for the first time after the data collection of the fiber 7 is completed by the movement of the compression roller 3 from A to B, and feeds back to the self-adjusting control system to make the self-adjusting control system execute corresponding actions. The second driving source 24 is stopped, and the first driving source 6 is started to move reversely, and the base 1, the moving mechanism 2 and the compression roller 3 move from B to C. The first driving source 6 is started to rotate forward again, and the second driving source 24 is started to rotate reversely, and the compression roller 3 moves from C to A'. At this time, the control system calculates the thickness value H1=h1+h2+…+hn of the fiber detected for the second time according to the second setting program, and feeds back to the self-adjusting control system to make the self-adjusting control system execute corresponding actions. The above is repeated until completion. Since the speed V1=the speed V2, the oblique lines between AC and A'B are only for the convenience of describing the trajectory of the compression roller 3, and are not actually oblique lines. The control system feeds back the thickness value of the fiber obtained each time to the self-adjusting control system, so as to adjust the working speed of the self-adjusting control system to ensure the self-adjusting of the fiber and improve the quality of the sliver. Figure 4 The oblique lines between AC and A'B are only for the convenience of describing the trajectory of the compression roller 3, and are not actually oblique lines. The control system feeds back the thickness value of the fiber obtained each time to the self-adjusting control system, so as to adjust the working speed of the self-adjusting control system to ensure the self-adjusting of the fiber and improve the quality of the sliver.
[0029] The present application detects by integral through the vertical downward pressure generated by the compression roller 3 pressing on the base surface 11. The data of the whole fiber sliver is established by the continuous detection of the vertical thickness at certain time interval. The vertical pressing process of the compression roller 3 is related to the subsequent feeding process, and the displacement control is realized by synchronous calculation. When the compression roller 3 moves, the base surface 11 and the compression roller 3 move along the Y direction synchronously with the fiber 7, so as to ensure that the movement direction of the compression roller 3 is perpendicular to the movement direction (Y) of the fiber 7.
[0030] For example, if the movement speed of the fiber along the Y direction is V1, the base is driven by the first driving source 6 to move along the Y direction at the speed V2=V1. If the distance between CB is S cm, the time used is S / V1. At the same time, the speed V3 of the compression roller is S1 / (S / V), wherein S1 is the distance between AB.
[0031] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent flow transformation by using the content of the specification and the drawings, or direct or indirect application in other related technical fields is also included in the patent protection range of the present application.
