[0039] The example embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent the same or similar elements. The following example embodiments described in the following description are not meant to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.
[0040] In the related art, performance evaluation is usually performed on a production line, which is time-consuming and costly.
[0041] To solve the problems in the related art, the present application provides a fiber bundle oil agent performance testing device, which includes an oven housing, and a first drying roller, a first oiling module and a scraping mechanism arranged in the oven housing. The first oiling module is configured to spray oil agent towards the outer circumferential surface of the first drying roller. The first drying roller is configured to dry the oil agent on the surface to form an oil film. The scraper of the scraping mechanism is configured to contact the outer circumferential surface of the first drying roller to scrape the oil film when the first drying roller rotates. In the testing device provided by the present application, the scraping mechanism can scrape the oil agent dried on the drying roller to form a sample to be tested, so as to detect the performance of the oil agent by experimental method, thereby reducing the cost of testing the performance of the oil agent on the production line.
[0042] According to an example embodiment of the present application, as shown in FIG. 1, a fiber bundle oil agent performance testing device includes an oven housing 10, a first drying roller 20, a first oiling module 30, a scraping mechanism 40, a second oiling module 50, a second drying roller 60, a traction roller 70 and a fiber bundle 100. Figure 1As shown, the embodiment provides a kind of oil agent performance testing device for fiber bundle, and oil agent performance testing device can carry out performance detection to the oil agent applied to fiber bundle, such as the film-forming ability of oil agent can be tested, film-forming ability refers to the ability of oil agent to form uniform, continuous film on the surface of fiber, mainly through the composition of oil agent (such as lubricant, emulsifier, high molecular polymer etc.) and formula design is realized, film-forming ability is strong or weak directly influences lubricity and friction control, antistatic performance, protection durability and post-processing adaptability etc.
[0043] As shown in Figure 1 , the oil agent performance testing device for fiber bundle includes an oven housing 10 for defining a drying space. The shape and structure of the oven housing 10 are not limited in this embodiment.
[0044] As shown in Figure 1 and Figure 2 , the oil agent performance testing device for fiber bundle further includes a first drying roller 20 and a first oiling module 30. The first drying roller 20 is rotatably arranged in the drying space defined by the oven housing 10, and the first oiling module 30 is arranged in the oven housing 10. The first oiling module 30 can spray oil agent towards the outer periphery of the first drying roller 20. During the spraying of oil agent by the first oiling module 30, the first drying roller 20 rotates to make the entire outer periphery be sprayed with oil agent, thereby forming an oil film covering the entire outer periphery of the first drying roller 20.
[0045] As shown in Figure 2 , the oil agent performance testing device for fiber bundle further includes a scraping mechanism 40 arranged in the oven housing 10. The scraping mechanism 40 is used to scrape the oil film covering the outer periphery of the first drying roller 20 at an appropriate time, and the scraped oil film can be used for performance detection. Referring to Figure 2 , the scraping mechanism 40 includes a driving unit 41 and a scraper 42 connected thereto. The driving unit 41 is configured to drive the scraper 42 to move relative to the first drying roller 20 so that the scraper 42 scrapes the oil film on the surface of the first drying roller 20.
[0046] In one example, referring to Figure 2 , the driving unit 41 can be a cylinder, an electric push rod or other driving units that can output linearly. The driving direction of the electric push rod is towards the first drying roller 20 (exemplarily, the straight line where the driving direction is located passes through the axis of the first drying roller 20). The driving unit 41 can drive the scraper 42 to move along the radial direction of the first drying roller 20 to approach or move away from the outer periphery of the first drying roller 20. When the scraper 42 approaches the first drying roller 20 and contacts or adheres to the outer periphery of the first drying roller 20, the oil film can be scraped.
[0047] In another example (not shown in the drawings), the driving unit can be a motor or the like capable of outputting torque. The driving unit can drive the scraper to rotate around a preset rotation axis, so that one side of the scraper approaches or moves away from the outer circumferential surface of the first drying roller. When the one side of the scraper approaches the outer circumferential surface of the first drying roller and contacts or adheres to the outer circumferential surface of the first drying roller, the oil film can be scraped off.
[0048] In the embodiments of the present application, the scraping mechanism can scrape off the oil agent on the drying roller to form a sample to be tested, so as to detect the performance of the oil agent by an experimental method, thereby reducing the cost of testing the performance of the oil agent on the production line.
[0049] In one example embodiment, as shown in Figure 1 and Figure 2 The present embodiment provides an oil agent performance testing device for fiber bundles, which includes an oven shell 10, a first drying roller 20, a first oiling module 30, and a scraping mechanism 40 arranged in the oven shell 10. The first oiling module 30 is configured to spray oil agent toward the outer circumferential surface of the first drying roller 20. The first drying roller 20 is capable of drying the oil agent on the surface to form an oil film. The scraping mechanism 40 is capable of contacting the outer circumferential surface of the first drying roller 20 to scrape off the oil film when the first drying roller 20 rotates.
[0050] As shown in Figure 2 , the scraping mechanism 40 is arranged obliquely below the first drying roller 20. By arranging the scraping mechanism 40 obliquely below the first drying roller 20, the separation position of the oil film from the first drying roller 20 can be located at a lower position of the first drying roller 20, so that the oil film can naturally sag after being separated to avoid the influence of winding and adhesion of the oil film on the test results. In one example, the included angle between the center line of the scraping mechanism 40 and the vertical line of the first drying roller 20 is about 45°.
[0051] As shown in Figure 2 , the included angle between the cutting surface of the scraping mechanism 40 and the first drying roller 20 is 40°-50°. The included angle is the included angle between the cutting plane of the blade of the scraping mechanism 40 and the tangent of the contact point of the outer circumferential surface of the first drying roller 20. In one example, the included angle is 45°. The 45° included angle is equal to the separation of the pressure of the scraping mechanism 40 on the outer circumferential surface of the first drying roller 20 along the normal direction (perpendicular to the outer circumferential surface) and the tangential direction (the rotation direction of the first drying roller 20), which can avoid excessive local stress to cause wear of the scraping mechanism 40 and the first drying roller 20. Of course, it can be understood that the included angle can be set to other angles according to actual needs, such as setting the included angle to 40° for stronger scraping force or setting the included angle to 50° for smaller wear.
[0052] In some embodiments (not shown in the drawings), the driving unit comprises a servo motor, an output shaft of the servo motor is connected with the scraper, and an axis direction of the output shaft of the servo motor is the same as an axis direction of the first drying roller. During the process that the first oiling module sprays the oil agent toward the first drying roller, the servo motor drives the scraper to rotate in the first direction, so that the first side of the scraper is away from the first drying roller and a preset interval is kept between the first side of the scraper and the surface of the first drying roller. During the process that the oil film is scraped off, the servo motor drives the scraper to rotate in the second direction, so that the first side of the scraper is attached to the surface of the first drying roller to scrape off the oil film. The first direction is opposite to the second direction.
[0053] In one example embodiment, as shown in Figure 1 and Figure 2 The present embodiment provides a fiber bundle oil agent performance testing device, which comprises a drying oven shell 10, a first drying roller 20, a first oiling module 30 and a scraping mechanism 40 arranged in the drying oven shell 10. The first oiling module 30 is used for spraying oil agent toward the outer surface of the first drying roller 20. The first drying roller 20 can dry the oil agent on the surface to form an oil film. The scraper 42 of the scraping mechanism 40 can contact the outer surface of the first drying roller 20 to scrape off the oil film when the first drying roller 20 rotates.
[0054] The fiber bundle oil agent performance testing device provided by the present embodiment can comprise any of the structures of the fiber bundle oil agent performance testing devices provided by the foregoing embodiments.
[0055] As shown in Figure 1 The fiber bundle oil agent performance testing device comprises the first oiling module 30 and a plurality of second drying rollers 60. The second oiling module 50 comprises an oiling groove. The fiber bundle can pass through the oiling groove to attach the oil agent to the surface. Then, the fiber bundle can pass through the plurality of second drying rollers 60. The plurality of second drying rollers 60 can dry the oil agent attached to the surface of the fiber bundle. After drying, the performance of the oil agent can be judged by observing the adhesion of the oil agent on the outer surface of the second drying roller 60. The adhesion of the oil agent affects the production efficiency and the surface quality of the fiber bundle. For example, a large amount of adhesion will result in low production efficiency and low quality of the fiber bundle.
[0056] As shown in Figure 1 and Figure 3As shown, multiple second drying rollers 60 are arranged in a staggered vertical arrangement. For example, taking five second drying rollers 60, the first, third, and fifth rollers are positioned at higher levels, while the second and fourth are positioned at lower levels. The fiber bundle 100 originates from the upstream device (upper oil tank), passes over the top of the first second drying roller 60, then descends to the bottom of the second second drying roller 60, then ascends to the top of the third second drying roller 60, then descends to the bottom of the fourth second drying roller 60, and finally ascends to the top of the fifth second drying roller 60 before exiting. In this embodiment, by arranging the multiple second drying rollers 60 in a continuous S-shaped transmission and by alternating the fiber bundle vertically among the rollers, the path length of the fiber bundle is extended, allowing it to remain in the drying zone for a longer period. This ensures sufficient contact with the radiant heat source, improving drying efficiency and quality, and facilitating tension control.
[0057] Among them, such as Figure 2 As shown, the first oiling module 30 includes an atomizer nozzle 31, which can disperse the oil into micron-sized droplets to form a uniform spray, so that the oil can more evenly cover the outer peripheral surface of the first drying roller 20, thereby forming a uniform oil film. Using an atomizer also has at least the following advantages, such as the ability to precisely control the spray volume and coverage area, and reduce oil waste.
[0058] Among them, such as Figure 1 and Figure 2 As shown, the atomizer nozzle 31 is connected to the upper oil tank. In this embodiment, since the oil in the upper oil tank has been in contact with the fiber bundle, using the oil in the upper oil tank is closer to the actual situation, which helps to improve the accuracy of the test. In some alternative embodiments, the atomizer nozzle 31 can be connected to other separate sample cells 32 that carry pure oil.
[0059] Among them, such as Figure 1 As shown, the fiber bundle oiling performance testing device also includes a traction roller 70, which is disposed at the inlet and outlet ends of the upper oil tank and the oven housing 10. The traction roller 70 is used to pull and tension the fiber bundle so that the fiber bundle can be automatically oiled, dried, and separated from multiple second drying rollers 60. In one example, the traction roller 70 uses two traction rollers 70 spaced apart vertically to clamp the traction fiber bundle.
[0060] Among them, such as Figure 1As shown, the top wall and side walls of the oven housing 10 are provided with observation windows 11. In one example, the observation windows 11 can be slidable, rotatable or detachable relative to the oven housing 10, so that the technician can take out the oil film from the oven housing 10 after completing the test. In another example, the observation windows 11 are provided as transparent pieces, so that the test result can be observed directly through the observation windows 11, for example, to observe the sticking of the oil agent on the second drying roller 60.
[0061] wherein, as shown, the axis direction of the first drying roller 20 is perpendicular to the axis direction of the second drying roller 60, and along the axis direction of the second drying roller 60, the first drying roller 20 and the second drying roller are arranged on two sides inside the oven housing 10. It can be understood that such an arrangement can make full use of the space inside the oven housing 10, facilitate the taking out of the oil film from the first drying roller 20, and facilitate the observation of the oil agent sticking on the second drying roller 60. Figure 4
[0062] Exemplarily, the oil film can be taken out by opening the observation windows 11 of the side walls of the oven housing 10, and the oil agent on the second drying roller 60 can be observed through the observation windows 11 of the top surface of the oven housing 10.
[0063] Other embodiments of the application will be apparent to those skilled in the art from consideration of the specification and practice of the aspects of the application disclosed herein. It is intended that the specification and examples be considered as exemplary only, with the true scope and spirit of the application being indicated by the following claims.
[0064] It is to be understood that the application is not limited to the precise construction described and shown herein and that various modifications and changes can be made by those skilled in the art without departing from the scope of the application. The scope of the application is limited only by the claims appended hereto.
