Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrospinning, and particularly relates to a control system for a full-automatic nano high-voltage spinning production line. Background Art
[0002] Electrospinning is a special form of electrostatic atomization of polymer fluids. At this time, the substances atomized and split are not tiny droplets, but polymer microjets, which can travel a considerable distance and finally solidify into fibers. Electrospinning is a special fiber manufacturing process in which a polymer solution or melt is sprayed and spun in a strong electric field. Under the action of the electric field, the liquid droplet at the needle tip will change from a spherical shape to a conical shape (i.e., "Taylor cone"), and a fiber filament will be extended from the tip of the cone. In this way, polymer filaments with a nanoscale diameter can be produced.
[0003] The current spinning process generally includes steps such as feeding, spinning, spraying glue, drying, and detecting. Among them, during the drying step, sufficient drying effect needs to be ensured to guarantee the quality of the spun fibers. However, when spinning different specifications, the solutions and the amounts of the solutions used are different, which leads to different drying times and temperatures required for complete drying. Therefore, manual adjustment is needed to adjust the drying time, temperature, etc. However, the efficiency of manual adjustment is low, which affects the production efficiency. Moreover, when the production line runs for a long time, equipment aging or failures will also cause problems in drying efficiency. Relying solely on manual discovery of problems and then making adjustments will result in a large number of unqualified products, and manual adjustment takes a long time, affecting the production efficiency. Summary of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a control system for a full-automatic nano high-voltage spinning production line, aiming to solve the problems in the prior art that the efficiency of manually adjusting the drying effect of the drying equipment according to different production conditions is low and not timely, affecting the overall production efficiency.

According to the sensing information of the sensing component, the control system controls the feeding device, the material receiving device, and the drying component to adjust the drying efficiency of the spun fibers.
[0006] The above-mentioned control system for the fully automatic nano high-pressure spinning production line dries the spun fibers on the substrate entering the drying box by setting a drying component in the drying box, and guides the movement of the substrate through a guide roller to control the movement trajectory of the substrate. Then, through the sensing component arranged at the discharge port of the drying box, the control system can obtain the drying effect of the drying device in real time. When there is a difference between the drying effect of the drying device and the expected effect, that is, when the drying degree of the spun fibers is too high or too low, the control system controls the feeding device and the receiving device to adjust the moving speed of the substrate, thereby adjusting the residence time of the substrate in the drying device, and further realizing the adjustment of the drying effect. In addition, the drying effect in the drying box can be directly adjusted by adjusting the power of the drying component, so that the drying effect of the drying device is appropriate.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0029] Please refer to Figures 1 to 3 , which shows the control system of a full-automatic nano high-voltage electrospinning production line in an embodiment of the present utility model. The high-voltage electrostatic spinning production line includes a feeding device 10, an electrostatic spinning device 20, a traction spraying device 30, a drying device 40, a detection device 50 and a material receiving device 60 that are distributed in sequence from upstream to downstream, where:
[0030] The drying device 40 includes a drying box 41, a drying component 42 provided in the drying box 41 and a guide roller 43 provided in the drying box 41. An outlet is provided on one side of the drying box 41 away from the traction spraying device 30. A sensing component 44 for detecting the humidity of the electrospinning on the substrate at the outlet is provided at the outlet. The moving speed of the substrate is controlled by the feeding device 10 and the material receiving device 60. The feeding device 10, the material receiving device 60 and the drying component 42 are controlled through the control system according to the sensing information of the sensing component 44 to adjust the drying efficiency of the electrospinning.
[0031] It can be understood that by arranging a drying component 42 in the drying box 41, the spinning on the substrate entering the drying box 41 is dried, and the movement of the substrate is guided by the guide roller 43 to control the movement track of the substrate. Then, through the sensing component 44 arranged at the discharge port of the drying box 41, the control system can obtain the drying effect of the drying device 40 in real time. When there is a difference between the drying effect of the drying device 40 and the expected effect, that is, when the drying degree of the spinning is too high or too low, the control system controls the feeding device 10 and the receiving device 60 to adjust the moving speed of the substrate, thereby adjusting the residence time of the substrate in the drying device, and then realizing the adjustment of the drying effect. In addition, the drying effect in the drying box 41 can be directly adjusted by adjusting the power of the drying component 42, so that the drying effect of the drying device 40 is appropriate. Therefore, the utility model solves the problem in the prior art that the efficiency of manually adjusting the drying effect of the drying equipment according to different production conditions is low and not timely, which affects the overall production efficiency.
[0032] It should be noted that, by way of example rather than limitation, in some alternative embodiments, in specific implementation, the substrate can be a long strip cloth-like material. The substrate moves under the action of the feeding device and the receiving device 60. At the electrospinning device 20, the solution forms spinning and adheres to the substrate under the action of high voltage. Then, it follows the substrate to the traction spraying device 30 for spraying glue, and then goes to the drying device 40 for drying. Among them, the receiving device 60 and the feeding device 10 can be composed of a driving roller, a guide roller 43, a fixed bracket and a motor 452. The driving roller is driven to rotate by the motor 452 and moves along a preset track under the action of the guide roller 43. Since these devices are not the key points protected by this case and there are many devices in the prior art that can achieve the same functions, the specific structure will not be elaborated too much.
[0033] Specifically, the drying box 41 is divided into an upper drying space 412 and a placement space 413 by a baffle 411. The guide roller 43 is arranged in the drying space 412 to tighten the substrate, and the drying component 42 is arranged in the placement space 413. The baffle 411 is provided with ventilation holes 414, so that the ventilation pipe 421 of the drying component 42 is communicated with the drying space 412 through the ventilation holes 414. By arranging the ventilation pipe 421 and the ventilation holes 414, the drying component 42 dries the inside of the drying space 412. By dividing the drying box 41 into two spaces, the gas flow direction in the drying space 412 can be adjusted targeted to ensure the drying effect in the space, and the drying effect is less affected by the outside and is convenient to adjust.
[0034] In addition, a discharge port and a feed port are respectively arranged on both sides of the drying space 412. Guide rollers 43 are provided at the feed port, the discharge port and the top of the drying space 412 to adjust the movement track of the substrate. By means of the guide rollers 43 arranged in the drying space 412, the substrate can move in the drying space 412 along a preset track, ensuring the drying effect of the substrate. Further, the sensing component 44 is located above the guide roller 43 at the discharge port, and a plurality of sensing parts are evenly distributed along the length direction of the guide roller 43. In a specific implementation, the substrate enters the drying space 412 from below the guide roller 43 at the feed port, moves above the guide roller 43 at the top of the drying space 412, then moves above the guide roller 43 at the discharge port and exits the drying space 412, and then enters the detection device 50 from below the guide roller 43 of the detection device 50 for detection. The substrate moves out of the drying space 412 between the sensing component 44 and the guide roller 43 at the discharge port, so that the sensing component 44 can effectively detect the drying effect of the spun fiber.
[0035] Specifically, adjusting components 45 for adjusting the height are symmetrically arranged on both sides of the guide roller 43 at the top of the drying space 412, so that the control system controls the travel of the substrate in the drying space 412 through the adjusting components 45 according to the information of the sensing component 44. In addition, in addition to adjusting the moving speed of the substrate by controlling the feeding device 10 and the winding device 60 to adjust the residence time of the spun fiber in the drying space 412, thereby adjusting the drying effect of the spun fiber, the position of the guide roller 43 at the top of the drying space 412 can also be adjusted through the adjusting components 45 to adjust the travel of the substrate in the drying space 412, so as to realize the adjustment of the residence time of the spun fiber in the drying space 412, thereby adjusting the drying effect of the spun fiber. Since the moving speed of the substrate will also affect the spinning effect at the electrospinning device 20, therefore, adjusting the drying effect through the adjusting components 45 has a relatively small impact on the overall production process.
[0036] In addition, the adjusting component 45 includes a mounting frame 451, a motor 452 and a screw rod 453 arranged on the mounting frame 451, and a slider 454 sleeved on the screw rod 453. The mounting frame 451 includes a slider 455 and a chute 456 arranged up and down. The motor 452 is arranged in the slider 455, the screw rod 453 is arranged in the chute 456, one side of the slider 454 is connected to the guide roller 43, and the motor 452 is used to control the rotation of the screw rod 453, so that the guide roller 43 moves up and down along with the slider 454. Specifically, the motor 452 drives the screw rod 453 to rotate, and then the guide roller 43 moves up and down along with the slider 454 to adjust the height of the guide roller 43, so that the travel of the substrate moving up and down changes, realizing the adjustment of the residence time of the spun fiber in the drying space 412, and further realizing the adjustment of the drying effect of the spun fiber.
[0037] Specifically, a plurality of guide rollers 43 and adjusting components 45 are equidistantly arranged along the length direction of the top of the drying space 412. By arranging a plurality of guide rollers 43 and adjusting components 45 at the top of the drying space 412, when the substrate passes through the top or bottom of each guide roller 43, and then by respectively adjusting the height of each guide roller 43, the adjustable range of the travel of the substrate in the drying space 412 is larger, and thus the adjustable range of the drying effect of the substrate is wider.
[0038] In addition, the drying component 42 includes a heating box 422, heating tubes 423 arranged in the heating box 422, ventilation pipes 421 arranged on both sides of the heating box 422 for communicating the heating box 422 and the drying space 412, and a blower 424 arranged on one side of the heating box 422 and communicating with the heating box 422. The blower 424 is used to blow the air heated by the heating tubes 423 in the heating box 422 into the drying space 412. Specifically, the air in the heating box 422 is heated by the heating tubes 423, and then the heated air is blown into the drying space 412 by the blower 424 to achieve the drying effect of the spun silk. In addition, according to the sensing information, the control system can adjust the drying effect machine in the drying space 412 by controlling the heating temperature of the heating tubes 423 and the rotation speed of the blower 424.
[0039] Specifically, the heating box 422 is divided into three heating spaces that are connected on one side by a partition 425. One side of the two end heating spaces is connected to the ventilation pipe 421, and the other side is connected to the middle heating space. The other side of the middle heating space is connected to the blower 424. By adjusting the space in the heating box 422 through the partition 425, the flow direction of the air in the heating box 422 is adjusted, so that the drying effect of the drying component 42 is better.
[0040] Specifically, a wind guide plate 415 is arranged on the top of the drying box 41, through holes are evenly distributed on the wind guide plate 415, and a wind guide cover 416 for connecting an external suction device is also arranged above the drying box 41. By arranging the wind guide plate 415 and the wind guide cover 416 on the top, the air in the drying space 412 moves in a specified direction to ensure the drying effect in the drying space 412.
[0041] It should be noted that the sensing component 44, the feeding device 10, the electrospinning device 20, the traction spraying device 30, the drying device 40, the detection device 50, the material receiving device 60, the adjustment component 45, etc. can adopt wireless communication methods such as WIFI, Bluetooth, infrared, radio frequency, etc. to communicate with the control system. Or the detection information can be uploaded through wired communication. For example, the control system of the fully automatic nano high-voltage spinning production line can be control terminal devices such as a control console, a workbench, a workstation, etc., and the control system of the fully automatic nano high-voltage spinning production line is communicatively connected to each device, equipment or sensing component 44 through a wire. By way of example rather than limitation, in some specific implementation cases, the sensing component 44 can adopt a humidity sensor, specifically, a microwave humidity sensor of Shanghai Haodun Electromechanical Technology Co., Ltd. The specific communication connection method and the specific model of the sensing component 44 are not the main points protected by this case and will not be elaborated here.
[0042] In summary, in the control system of the fully automatic nano high-voltage spinning production line in the above embodiments of the present invention, the drying component 42 is arranged in the drying box 41 to dry the spinning on the substrate entering the drying box 41, and the guide roller 43 is used to guide the movement of the substrate and control the movement trajectory of the substrate. Then, through the sensing component 44 arranged at the outlet of the drying box 41, the control system can obtain the drying effect of the drying device 40 in real time. When there is a difference between the drying effect of the drying device 40 and the expected effect, that is, when the drying degree of the spinning is too high or too low, the control system controls the feeding device 10 and the material receiving device 60 to adjust the moving speed of the substrate, and then adjusts the residence time of the substrate in the drying device, so as to realize the adjustment of the drying effect. In addition, the drying effect in the drying box 41 can be directly adjusted by adjusting the power of the drying component 42, so that the drying effect of the drying device 40 is appropriate. Therefore, the present invention solves the problem in the prior art that the efficiency of manually adjusting the drying effect of the drying equipment according to different production conditions is low and not timely, which affects the overall production efficiency.
