[0029] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0030] Reference to an "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present disclosure. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] In the drying process of preparing carbon fiber spinning, drying rollers are generally used to dry the carbon fiber spinning. However, since there will be a large amount of oil on the surface of the carbon fiber spinning, a large amount of oil stains will adhere to the surface of the drying roller during the drying process. The oil stains will form a thick layer of covering on the surface of the drying roller, which reduces the drying effect of the drying roller. In order to deal with the oil stain covering, a scraper is generally set on the outside of the drying roller body to scrape off the covering on the roller surface, but the scraped covering will scatter everywhere, causing the working environment and equipment to be polluted again, affecting the quality of the product.

[0032] In order to solve the problems existing in the related art, the exemplary embodiment of the present disclosure provides a drying device, which includes: a fixed bracket, a drying roller and a cleaning assembly; wherein the drying roller is rotatably connected to the fixed bracket; the cleaning assembly is connected to the fixed bracket, and the cleaning assembly includes a first box, an air extraction unit, an air extraction pipeline and a second box, and the air extraction unit is connected to the second box through the first box and the air extraction pipeline; wherein the second box has a first opening on the side facing the drying roller, and a scraper is provided on the side of the first opening close to the drying roller. The drying device can scrape off the grease covering on the surface of the drying roller to avoid the drying effect of the drying roller being reduced due to the grease covering on the surface of the drying roller. In addition, the grease covering can be collected after scraping to prevent the scraped grease covering from scattering, effectively avoiding the grease covering scattering after scraping to pollute the surrounding environment and equipment, and at the same time, it can also prevent quality damage during carbon fiber spinning production.

[0033] like Figure 1-3 As shown, the drying device 100 provided by the above exemplary embodiment, in one embodiment, for example, after a batch of carbon fiber spinning is completed, the surface of the drying roller 20 is covered with an oily covering. Since the scraper 36 (for example, a scraper) is in contact with the surface of the drying roller 20, the drying roller 20 is controlled to rotate, and the oily covering on the surface of the drying roller 20 can be scraped off by the scraper 36, thereby ensuring the drying effect of the drying roller 20 in subsequent use and avoiding a decrease in the drying effect of the drying roller 20 due to the oily covering on the surface of the drying roller 20. After the scraper 36 scrapes off the grease coating on the surface of the drying roller 20, the exhaust unit 32 (for example, a suction fan) is started to generate suction, and the grease coating scraped off by the scraper 36 is sucked into the second box 34 through the first opening 35, and then sucked into the first box 31 through the exhaust pipe 33 for collection, which can prevent the scraped grease coating from scattering, effectively avoiding the pollution to the surrounding environment and equipment caused by the scattering of the grease coating after scraping, and at the same time prevent quality damage during carbon fiber spinning production.

[0034] In the exemplary embodiments provided in the present disclosure, Figure 1 and Figure 4 As shown, the first housing 31 includes a first shell 311 and a second shell 312. The first shell 311 is connected to the fixing bracket 10, and along the axial direction of the drying roller 20, the first side wall 3111 of the first shell 311 is provided with a first through hole 3112, and the air extraction unit 32 is connected with the interior of the first shell 311 through the first through hole 3112. The second shell 312 is arranged in the first shell 311 and is slidably connected with the first shell 311, and the filter 3121 constitutes the side wall 3122 of the second shell 312, and the filter 3121 is opposite to the first side wall 3111.

[0035] In one example, if Figure 1-4 As shown, the scraper 36 scrapes off the grease covering on the surface of the drying roller 20. The air extraction unit 32 is connected to the interior of the first housing 311 through the first through hole 3112. When the air extraction unit 32 is started, suction is generated to suck the grease covering scraped off by the scraper 36 into the second housing 34 through the first opening 35, and sucked into the interior of the first housing 31 through the air extraction pipeline 33 for collection. The side wall 3122 directly opposite to the first side wall 3111 is set as a filter 3121, which can prevent the suction generated by the air extraction unit 32 from sucking the grease covering into the air extraction unit 32, thereby avoiding damage to the air extraction unit 32 and affecting the service life of the air extraction unit 32. The second shell 312 is slidably connected to the first shell 311. After the first box body 31 is full of grease and dirt, the second shell 312 can be pulled out from the first shell 311 by the pulling handle 3123 on the second shell 312 to clean the grease and dirt and impurities inside the second shell 312. After cleaning, it can be reinserted into the first shell 311 for continued use. This is convenient and quick, and there is no need to disassemble the device.

[0036] In the exemplary embodiments provided in the present disclosure, Figure 1 , Figure 4 and Figure 5 As shown, a second through hole 3113 is provided on the top wall of the first shell 311 , and the air extraction pipeline 33 is connected with the interior of the first shell 311 through the second through hole 3113 .

[0037] In one example, if Figure 1-5 As shown, the scraper 36 scrapes off the oily dirt covering on the surface of the drying roller 20. The air extraction pipeline 33 is connected to the interior of the first housing 311 through the second through hole 3113. When the air extraction unit 32 is started, suction is generated to suck the oily dirt covering scraped off by the scraper 36 into the second housing 34 through the first opening 35, and then sucked into the interior of the first housing 31 through the air extraction pipeline 33 and the second through hole 3113 for collection, which can prevent the scraped oily dirt covering from scattering, effectively avoiding the oily dirt covering scattering after being scraped off from polluting the surrounding environment and equipment, and also preventing quality damage during carbon fiber spinning production.

[0038] In the exemplary embodiments provided in the present disclosure, Figure 2 and Figure 5As shown, the air extraction pipeline 33 includes a connecting pipe 331 and a plurality of hoses 332. When the air extraction unit 32 is started, suction is generated to suck the oil and dirt covered by the scraper 36 into the second box 34 through the first opening 35, and then sucked into the first box 31 through the plurality of hoses 332 and the connecting pipe 331 for collection. Among them, the soft structure of the hose 332 can ensure that the cylinder 104 flexibly pushes the second box 34 to move toward the direction close to the drying roller 20.

[0039] In the exemplary embodiments provided in the present disclosure, Figure 1 and Figure 4 As shown, the first box body 31 is columnar, and the extension direction of the first box body 31 is parallel to the axial direction of the drying roller 20. For example, the first box body 31 may be cylindrical or prism-shaped, for example, it may be rectangular. Setting the first box body 31 in a columnar shape can reduce the area of ​​the filter screen 3121 on the second side wall 3122 of the second shell 312, saving manufacturing costs, and setting the first box body 31 in a columnar shape and placing it horizontally so that the first box body 31 is parallel to the axial direction of the drying roller 20, can be matched with other components in the drying device 100, fully utilizing the internal space of the fixing bracket 10, and facilitating assembly.

[0040] In the exemplary embodiments provided in the present disclosure, Figure 1 As shown, the arrangement direction of the first box body 31 and the exhaust unit 32 is parallel to the axial direction of the drying roller 20. This arrangement can make full use of the internal space of the fixed bracket 10 and ensure that the exhaust path of the first box body 31 and the exhaust unit 32 is a straight path, reducing the suction loss caused by multiple turns.

[0041] In the exemplary embodiments provided in the present disclosure, Figure 1 and Figure 6 As shown, a second fixed plate 103 is also provided on the fixed bracket 10, and the extension direction of the second fixed plate 103 is parallel to the axial direction of the drying roller, and the first box body 31 and the air extraction unit 32 are fixedly connected to the second fixed plate 103. For example, the first box body 31 and the air extraction unit 32 are arranged in a direction parallel to the axial direction of the drying roller 20 and are fixedly connected to the second fixed plate 103. In this way, the internal space of the fixed bracket 10 can be fully utilized, the first box body 31 and the air extraction unit 32 are assembled in the fixed bracket 10, and it is ensured that the air extraction path of the first box body 31 and the air extraction unit 32 is a straight path, thereby reducing the suction loss caused by multiple turns.

[0042] In the exemplary embodiments provided in the present disclosure, Figure 1 and Figure 4As shown, a second opening 313 is provided on the side of the first housing 311 away from the drying roller 20, and the second housing 312 enters the first housing 311 through the second opening 313, and the first housing 311 and the second housing 312 form a drawer structure. The second housing 312 is slidably connected to the first housing 311 and enters the first housing 311 through the second opening 313. After the first box 31 is full of grease and dirt covering, the second housing 312 can be pulled out from the inside of the first housing 311 by the pull handle 3123 on the second housing 312, and the grease and dirt covering and impurities inside the second housing 312 can be cleaned. After cleaning, it can be reinserted into the first housing 311 for continued use, which is convenient and quick, and there is no need to disassemble the device.

[0043] In the exemplary embodiments provided in the present disclosure, Figure 6 As shown, two sides of the fixed bracket 10 are provided with slide grooves 101. Figure 5 As shown, sliders 341 are provided on both sides of the second box body 34, and the sliders 341 are slidably connected to the inside of the slide groove 101. In one example, the movement of the second box body 34 is limited by fixing the slide grooves 101 on both sides of the bracket 10 and the sliders 341 on both sides of the second box body 34, so as to prevent the second box body 34 from being offset in the axial direction of the drying roller 20, thereby affecting the cleaning work of the drying roller 20.

[0044] In the exemplary embodiments provided in the present disclosure, Figure 1 and Figure 6 As shown, a first fixed plate 102 is provided on the fixed bracket 10, and the extension direction of the first fixed plate 102 is parallel to the axial direction of the drying roller 20. A cylinder 104 is provided on the side of the first fixed plate 102 close to the drying roller 20, and the telescopic end of the cylinder 104 is fixedly connected to the second box body 34, and the telescopic direction of the cylinder 104 is parallel to the extension direction of the slide groove 101.

[0045] In one example, the cylinder 104 pushes the second box body 34 to move toward the outside of the drying roller 20, so that the scraper 36 fits against the surface of the drying roller 20, and under the rotation of the drying roller 20, the scraper 36 scrapes off the oil and dirt covering the surface of the drying roller 20. When the scraping is completed, the cylinder 104 can drive the second box body 34 to reset so that it does not affect the normal use of the drying roller 20 in the carbon fiber spinning process.

[0046] In the exemplary embodiments provided in the present disclosure, Figure 2 and Figure 3As shown, the cleaning assembly 30 further includes a cleaning brush 37. In one example, the scraper 36 is in contact with the surface of the drying roller 20, and the scraper 36 scrapes off the oil and dirt covering on the surface of the drying roller 20 as the drying roller 20 rotates. As the drying roller 20 rotates, the cleaning brush 37 cleans the scraped portion of the surface of the drying roller 20 to further clean the drying roller 20. The cleaning brush 37 is detachably connected to the side of the first opening 35 on the second housing 34 close to the drying roller 20. For example, the cleaning brush can be detachably connected to the side of the first opening 35 on the second housing 34 close to the drying roller 20 by bolts. When the cleaning brush 37 is used for a long time, the bolts can be removed, so that the cleaning brush 37 can be removed for replacement, or the cleaning brush 37 can be cleaned to extend the service life of the cleaning brush 37.

[0047] In the exemplary embodiments provided in the present disclosure, Figure 1 and Figure 3 As shown, the scraper 36 is tilted at a second preset angle with respect to the horizontal plane, and the second preset angle can be 0°-90°. The scraper 36 is tilted so that the side of the scraper 36 that is in contact with the drying roller 20 can apply force to the surface of the drying roller 20 to scrape off the grease covering on the surface of the drying roller 20. In one example, refer to Figure 2 , showing that the second preset angle is 60°. The second box 34 is tilted at a first preset angle with respect to the horizontal plane, and the first preset angle can be 0°-90°. The second box 34 is tilted to increase the area where the second box 34 generates suction on the surface of the drying roller 20. After the scraper 36 scrapes off the grease covering on the surface of the drying roller 20, the grease covering is directly sucked into the second box 34. In one example, refer to Figure 2 , showing that the first preset angle is 45°.

[0048] In the exemplary embodiments provided in the present disclosure, Figure 1-3As shown, the cylinder 104 and the air extraction unit 32 can be connected to the control system (not shown in the figure). After the drying roller 20 is used for a certain period, such as a certain carbon fiber spinning production batch cycle or a long period, the control system controls the air extraction unit 32 to start to extract air and generate suction, and at the same time controls the cylinder 104 to push the second box 34 to move to the outside of the drying roller 20, so that the scraper 36 fits the surface of the drying roller 20, and under the rotation of the drying roller 20, the scraper 36 scrapes off the grease covering on the surface of the drying roller 20. After the scraping is completed, the control system controls the cylinder 104 to drive the second box 34 to reset so that it does not affect the normal use of the drying roller 20 in the preparation of carbon fiber spinning, and closes the air extraction unit 32. It can be understood that in addition to automatically controlling the start and stop of the cylinder 104 and the air extraction unit 32 after the drying roller 20 is used for a certain period, the control system can also be operated by the operator to control the start and stop of the cylinder 104 and the air extraction unit 32.
