Description

Technical Field

[0001] The present invention relates to the technical field of electrostatic spinning processing, and in particular to an electrostatic spinning online detection device and a control method. Background Art

[0002] Electrospinning is a special form of electrostatic atomization of polymer fluids. The substances split by the atomization are not tiny droplets, but tiny polymer jets that can travel a considerable distance and eventually solidify into fibers. Electrospinning is a special fiber manufacturing process. Polymer solutions or melts are jet-spun in a strong electric field. Under the action of the electric field, the droplets at the needle tip will change from spherical to conical (i.e., "Taylor cone"), and extend from the tip of the cone to obtain fiber filaments.

[0003] In the electrospinning production and processing stage, it passes through the substrate release section, electrospinning section, main traction spraying and compounding section, drying treatment section, air permeability uniformity online detection section and slitting and winding section in sequence.

[0004] The existing permeability test for spinning is to blow air on the unfolded spinning surface and obtain the wind pressure passing through the spinning by the pressure sensor at the bottom of the spinning to determine the permeability of the spinning in the current test area. However, this measurement method can be understood as a comprehensive measurement. For example, for the detection of the overall permeability of the spinning in the blowing area, it is impossible to accurately detect the specific area with poor permeability in the area and mark the current area, resulting in large errors in the measurement data. Conversely, due to the increase in the spinning measurement error, a large amount of qualified material will be cut in the subsequent segmented cutting process based on the permeability quality, resulting in material waste.

[0017] The receiving assembly guides the yarn to be tested into the detection area at a preset uniform speed, and controls the blowing assembly to blow air at a preset wind speed on the surface of the yarn to be tested, so that the yarn to be tested drives the multiple pneumatic blades at the bottom of the yarn to be tested to rotate;

[0040] Example 1

[0041] See also Figures 1 to 7 , shown is an electrospinning online detection device in an embodiment of the present invention, including a blast assembly 1 arranged on the top, a detection assembly 3 arranged at the bottom of the blast assembly 1, a flattening component 2 arranged between the blast assembly 1 and the detection assembly 3, a receiving assembly 4 connected to the same side of the blast assembly 1 and the detection assembly 3 respectively, and a material receiving rack 5 arranged on the side of the detection assembly 3 away from the receiving assembly 4. The flattening component 2 includes a clamping portion 21 for guiding the spinning transmission path, two sets of transmission wheels 22 arranged on the inner side of the clamping portion 21 and opposite to each other. It should be noted that the two sets of transmission wheels 22 are in contact with each other, and the surface is wrapped with a rubber sleeve to ensure that the spinning is clamped and transmitted while avoiding damage to the spinning caused by hard contact between the transmission wheel 22 and the spinning. The flattening component 2 also includes a marking component 23 embedded in the clamping portion 21 and moving toward or away from the two sets of transmission wheels 22. The marking component 23 and the detection assembly 23 are connected to each other. The assembly 3 is electrically connected, and the detection assembly 3 includes a detection platform 31 embedded in the top of the flattening component 2. The detection platform 31 includes a fixed frame 311, a fixed grid 312 arranged on the inner side of the fixed frame 311, and a plurality of pneumatic blades 313 driven by the blowing assembly 1 arranged on the fixed grid 312. In some optional embodiments, the plurality of pneumatic blades 313 are electrically connected to the flattening component 2, so as to be used for the subsequent determination of the spinning with poor air permeability through the speed information fed back by the pneumatic blades 313, and to correspondingly wake up the marking component 23 in the flattening component 2 to mark the unqualified area, wherein the spinning on the material receiving frame 5 is driven by the material receiving assembly 4 to be flattened and passed between the two sets of transmission wheels 22. During this period, air is blown toward one side of the spinning through the blowing assembly 1, and the plurality of pneumatic blades 313 on the spinning drive fixed frame rotate, and the air permeability of the corresponding spinning area is determined according to the speed of the plurality of pneumatic blades 313.

[0042] Furthermore, the blower assembly 1 includes a blower box 11 fixedly connected to the flattening component 2, a filter layer 12 at least partially embedded in the blower box 11 away from the flattening component 2, a sliding frame 14 slidably arranged inside the blower box 11, and a blower 15 arranged in the middle of the sliding frame 14. At least two slide grooves 13 for accommodating the sliding frame 14 are embedded inside the blower box 11. The marking component 23 includes a fixing portion 231 embedded in the clamping portion 21, a fixing portion 231 extending along the top of the clamping portion 21 toward the bottom of the marking component 23. The fixed portion 231 is embedded with an ink cartridge 232, a marking end embedded in the fixed portion 231 and at least partially connected to the ink cartridge 232, and a telescopic portion 234 embedded in the fixed portion 231 for driving the marking end to move toward or away from the transmission wheel 22. The marking end includes an ink outlet portion 235 fixedly arranged at the output end of the telescopic portion 234, and a marking brush 236 arranged on the side of the ink outlet portion 235 away from the telescopic portion 234. The two sides of the ink outlet portion 235 are respectively connected to the marking brush 236. 6 is connected to the ink storage box 232, the material receiving assembly 4 includes a material pressing piece movably arranged on the outside of the blow box 11, and a material receiving piece fixedly arranged on the outside of the detection assembly 3 and located below the material pressing piece, the material receiving piece includes at least two fixed frames 41 fixedly connected to the detection assembly 3, a material receiving roller 43 movably arranged between the two fixed frames 41, and a motor 42 fixed on one side fixed frame 41 and axially connected to the material receiving roller 43, the material pressing piece includes at least two damping shafts 44 connected to the outside of the blow box 11, a second fixed frame 45 arranged on the side of the damping shaft 44 away from the blow box 11, and a pressure roller 46 movably arranged on the side of the second fixed frame 45 away from the damping shaft 44. It should be noted that the material receiving piece and the material supporting frame 5 are of relative structural design, and the material receiving roller 43 is of detachable design between the side of the motor 42 and the fixed frame 41, and the material receiving roller 43 can be connected to the fixed frame 41 by bolt clamping or overlapping to facilitate the subsequent loading and unloading of the spinning roll.

[0043] During the specific implementation, the operator can first put the spinning roll on the material support frame 5, guide the opening of the spinning roll through the flattening component 2, and ensure that both sides of the spinning are clamped between the two sets of transmission wheels 22 to implement preliminary clamping of the spinning to ensure the tension on both sides of the spinning, and then continue to guide the spinning that passes through the flattening component 2 to be wound on the receiving roller 43 to complete the connection between the spinning and the electrostatic spinning online detection device and implement the detection operation. In some optional embodiments, a control console can be set at a convenient operating position on the electrostatic spinning online detection device. In addition, the control console can be an MCU (Microcontroller Unit; micro control unit) chip to control the electrostatic spinning online detection device through the MCU chip, wherein the electrostatic spinning online detection The detection device and the control console can also be electrically connected, and the electrical connection includes wired connection and wireless connection. The wireless connection method includes but is not limited to Bluetooth connection, WiFi, IF radio frequency, zigbee, and the wired connection method includes but is not limited to a USB line connecting the electrostatic spinning online detection device to the control console. For the specific detection of spinning, the operator can control the motor 42 to turn on through the control console, and the motor 42 drives the receiving roller 43 to drive the spinning to implement uniform speed winding. It can be understood that the drive of the motor 42 also serves as the main power source for spinning transmission. In some optional embodiments, in order to ensure the surface tension of the spinning during the transmission process, the structure on the material support frame 5 relative to the receiving roller 43 is called the discharge roller, and the discharge roller The fixing frame 41 on the same side can be connected with it through a second damping shaft, so that when the motor 42 drives the material collection roller 43 to reel in the spinning, the design of the second damping shaft on the material discharge roller will generate resistance in the opposite direction of the output direction of the motor 42, and form a certain tension on the spinning in the reeling process under the relative force, and cooperate with the transmission tension of the clamping part 21, so that the spinning has good tension on all sides after entering the flattening component 2, which greatly guarantees the flatness of the spinning and ensures the accuracy of the data during the subsequent spinning permeability test. After that, the spinning in the flattening component 2 is tested, and the operator can control the motor 42 to turn off and control the blower assembly 1 to turn on. After turning off the motor 42, the tension applied to the spinning surface may disappear. In order to affect subsequent detection, in some optional embodiments, a pressing piece can be provided above the receiving piece and the discharging piece, wherein the pressure roller 46 on the pressing piece is in elastic contact with the receiving roller 43, specifically through the damping shaft 44 connected to one side of the blow box 11 by the pressing piece. In addition, the damping shaft 44 can also be a spring shaft, so that the pressure roller 46 can be adaptively adjusted in angle according to the diameter of the spinning roll on the receiving roller 43, and the pressure roller 46 is always in contact with the surface of the spinning roll to ensure that when the motor 42 is turned off, the surface tension of the spinning is ensured by pressing the two ends of the spinning by the pressure roller 46, and then the blower 15 is controlled to be turned on to generate uniform wind to blow the spinning surface below. In some optional embodiments of the present invention, due to the difference in the weaving density of different spinnings,This causes different air permeability in the spinning. Therefore, in order to ensure that the wind can pass through the spinning smoothly, for spinning with a denser weaving density, the operator can use the sliding frame 14 to drive the blower 15 along the track of the slide 13 toward the side close to the spinning. The sliding frame 14 is composed of a gear embedded in the slide 13, a second motor for driving the gear, and a fixed rod connecting the second motor and the blower 15. The corresponding slide 13 is provided with a rack adapted to the gear, so that the operator can adjust the distance between the blower 15 and the spinning according to the spinning weaving density. In addition, during the blowing process, in order to prevent external environmental impurities from being sucked into the blower 15 and blown to the spinning surface to affect its air permeability detection, a filter layer 12 is also provided at the suction point of the blower 15 to effectively filter air impurities and avoid affecting the air permeability of the spinning surface.

[0044] Then, the wind passing through the top of the spinning machine to the bottom will drive the pneumatic blades 313 on the detection platform 31 to rotate, and the processor set in the detection assembly 3 will uniformly collect the rotation speed information of all the pneumatic blades 313. In some optional embodiments, in order to avoid the fixed grid 312 limiting the arrangement area of ​​the pneumatic blades 313 and causing certain errors in the air permeability test data, the pneumatic blades 313 can be set above the fixed grid 312, and an air guide port connected to the outside world can be opened at the bottom of the pneumatic blades 313 on the detection platform 31 to guide the air guide port that passes through the pneumatic blades 313 to be discharged, so as to avoid the wind that passes through the pneumatic blades 313 rebounding after flowing to the bottom of the detection platform 31 and the rebound wind acting on the bottom of the pneumatic blades 313, thereby affecting its rotation effect and causing measurement data errors. The processor can be understood by those skilled in the art. For example, it can be considered as a sequenced list of executable instructions for realizing logical functions, and can be specifically implemented in any computer-readable medium for instruction execution systems and devices. Or equipment (such as a computer-based system, a system including a processor, or other system that can fetch and execute instructions from an instruction execution system, device, or equipment), and then the processor analyzes the collected rotational speeds of each pneumatic blade 313, based on the preset rotational speed standard range stored in the processor, which is also the standard range defined by the technical personnel in this field according to the spinning weaving density, which is understandable to those skilled in the art and will not be elaborated on here, and the processor compares the pneumatic blades 313 one by one to see if they are within the rotational speed standard range. If so, it is determined that the current qualified pneumatic blade 313 is projected to the spinning area directly above to meet the air permeability standard. If not, the position of the unqualified pneumatic blade 313 is obtained and projected to the spinning area directly above, and the distance between the current area and the marking component 23 is obtained. According to the distance and the transmission speed after the subsequent motor 42 is turned on, the time required for the unqualified spinning area to reach the marking component 23 is determined, and the marking component 23 is turned on accordingly to perform a marking operation on the spinning of the unqualified area.

[0045] The marking operation is performed on the spinning of unqualified areas through the marking component 23. Specifically, after the motor 42 is turned on for the required time, the processor transmits information to the control console to control the telescopic part 234 to turn on. In some optional embodiments, the telescopic part 234 can be an electric telescopic rod. Thereafter, the telescopic part 234 pushes the ink outlet part 235 and the marking brush 236 toward the spinning side, and enables the marking brush 236 to apply a brush mark to the spinning side, so that subsequent operators can perform cutting operations on the spinning according to the marked position.

[0046] In summary, the electrospinning online detection device in the above-mentioned embodiment of the present invention drives the spinning on the material receiving frame 5 to be flattened and passed between the two sets of transmission wheels 22 through the material receiving assembly 4. During this period, the air is blown toward the spinning side through the blowing assembly 1, and rotates through the multiple pneumatic blades 313 on the spinning drive fixed frame, and the air permeability of the corresponding spinning area is determined according to the rotation speed of the multiple pneumatic blades 313. This method covers the detection area through multiple pneumatic blades 313, and it can be understood that the detection area is divided into multiple groups of small areas, and the air permeability of different spinning areas is judged one by one by the pneumatic blades 313 in the area, thereby improving the measurement accuracy and solving the problem that the existing measurement means can be understood as a comprehensive measurement, such as the detection of the overall air permeability of the spinning in the blasting area, which cannot accurately detect the specific area with poor permeability in the area and mark the current area, resulting in large errors in the measurement data.

[0047] Example 2

[0048] See also Figure 8 , which shows a control method for an electrospinning online detection device in a second embodiment of the present invention, and is applied to an electrospinning online detection device. The method specifically includes steps S01 to S06.

[0049] In step S01, the receiving assembly guides the yarn to be inspected into the inspection area at a preset uniform speed, and controls the blowing assembly to blow air at a preset wind speed on the surface of the yarn to be inspected, so that the yarn to be inspected drives multiple pneumatic blades at the bottom of the yarn to be inspected to rotate.

[0050] Step S02, obtaining the rotational speed information of the plurality of wind-driven blades, and determining whether the rotational speed information meets a preset rotational speed, if so, executing step S03, if not, executing step S04.

[0051] Step S03, determining whether the spinning to be inspected in the area opposite to the pneumatic blade is qualified.

[0052] Step S04: determining whether the spinning to be inspected in the area opposite to the pneumatic blade is unqualified.

[0053] Step S05, determining the position information of the pneumatic blade corresponding to the unqualified spinning area to be inspected, obtaining the distance information between the position information and the marking component, and obtaining the preset uniform speed information of the spinning to be inspected entering the inspection area;

[0054] Step S06, determining the time required for the position information of the pneumatic blade to reach the marking component based on the spacing information and the uniform speed information, and waking up the marking component to extend toward the spinning side based on the time information to mark the unqualified spinning area.

[0055] In summary, the control method of the electrospinning online detection device in the above embodiment guides the spinning to be detected into the detection area at a preset uniform speed through the material receiving assembly, and controls the blowing assembly to blow air on the surface of the spinning to be detected at a preset wind speed, so that the spinning to be detected drives the multiple pneumatic blades at the bottom of the spinning to be detected to rotate, and determines the unqualified area on the spinning by judging the rotation speed of the pneumatic blades, and determines the area position and the distance information between the area and the marking component. The time required for the unqualified area to reach the marking component is obtained by combining the spacing information with the uniform transmission speed of the material receiving assembly, and finally the marking component extends toward one side of the spinning after the required time and marks the unqualified spinning area.
