Description

Technical Field

[0001] This application relates to the field of carbon fiber production technology, and more specifically, to a water washing device and a carbon fiber production line. Background Technology

[0002] In carbon fiber production, surface treatment improves the adhesion between carbon fibers and the resin matrix, thereby increasing the interlaminar shear force of the composite material and further enhancing its performance. However, the anodic electrolytic surface treatment method introduces metal ions. If these ions are not completely removed during the washing stage, they can negatively impact the performance of both the carbon fiber and the composite material. Therefore, it is necessary to measure the conductivity of the water in the washing section of the surface treatment process. However, due to the wide production line (i.e., the large tank width) and the corrosiveness of some electrolyte solutions, obtaining water samples in the washing section is difficult and can easily cause injury to sampling personnel. Utility Model Content

[0003] The purpose of this application is to provide a water washing device and a carbon fiber production line that facilitates water sampling in a water tank.

[0004] The embodiments of this application are implemented as follows:

[0005] In a first aspect, embodiments of this application provide a washing device, including a water tank, the top of which has an opening for a filament bundle to pass through, a grooved roller for conducting the filament bundle is disposed inside the water tank, and a liquid extraction device is disposed above the grooved roller for extracting liquid from the water tank, the liquid extraction device being configured to move along the axial direction of the grooved roller.

[0006] In the above technical solution, the water tank is used to contain the cleaning solution for cleaning the filament bundle. The groove roller serves to conduct the filament bundle and change its trajectory, allowing it to pass through the cleaning solution. By installing a liquid extraction device above the groove roller, the cleaning solution in the water tank can be extracted, enabling sampling and reducing the risk of personnel being corroded by the cleaning solution during manual sampling. Since the liquid extraction device can move along the axial direction of the groove roller, sampling is significantly easier when the water tank is large in this direction.

[0007] In some alternative implementations, the water tank is provided with a first guide rail, which is arranged parallel to the axial direction of the tank roller, and the liquid pumping device is arranged on the first guide rail and can move along the axial direction of the first guide rail.

[0008] In the above technical solution, the liquid extraction device is set on the first guide rail and can move along the axial direction of the first guide rail. This allows the liquid extraction device to move to multiple positions for sampling. Since the liquid extraction device is set on the first guide rail, the movement of the liquid extraction device is more stable.

[0009] In some alternative implementations, the pumping device includes a first drive member and a water pump slidably disposed on the first guide rail, the first drive member being connected to the water pump to drive the water pump to move along the first guide rail.

[0010] In the above technical solution, the water pump is driven to move along the first guide rail by the first driving component, which makes it easier for the water pump to automatically move along the first guide rail to the position where sampling is required, and the operation is more convenient.

[0011] In some alternative embodiments, the pumping device includes a lead screw and nut mechanism, wherein the first guide rail is a lead screw and the water pump is disposed on the nut; the first driving member is used to drive the first guide rail to rotate.

[0012] Alternatively, the first driving component may be a pneumatic cylinder or a hydraulic cylinder, and the water pump may be connected to the piston rod of the first driving component.

[0013] In the above technical solution, a lead screw and nut mechanism, or a cylinder, or a hydraulic cylinder is used to drive the water pump, which makes it easier for the water pump to automatically move along the first guide rail to the position where sampling is required, and the operation is more convenient.

[0014] In some alternative implementations, the water pump inlet is connected to a first pipe with its opening facing the bottom of the water tank, the first pipe being configured to extend or retract toward or away from the bottom of the tank.

[0015] In the above technical solution, the first pipe can extend towards the bottom of the tank, so that the pipe opening can be extended below the surface of the cleaning liquid in the tank for sampling; the first pipe can also retract away from the bottom of the tank to reduce the resistance that the water pump needs to overcome during operation and to reduce the possibility of the first pipe colliding with other structures.

[0016] In some alternative implementations, the outlet of the water pump is connected to a second pipe, which is a flexible hose.

[0017] In the above technical solution, since the second pipe is a flexible hose, it is easy to bend and connect to the container used to hold the water sample.

[0018] In some alternative embodiments, a second guide rail is also included, with a plurality of grooved rollers arranged side by side along the extension direction of the second guide rail, the second guide rail being located above the grooved rollers, and the first guide rail being slidably disposed on the second guide rail.

[0019] In the above technical solution, by setting a second guide rail and slidably setting the first guide rail on the second guide rail, the first guide rail can move along the extension direction of the second guide rail, and then move to the location of different groove rollers for sampling.

[0020] In some alternative implementations, a second drive member is also included, which is connected to the first guide rail to drive the first guide rail to move along the second guide rail.

[0021] In the above technical solution, the first guide rail is driven to move along the second guide rail by the second driving component, which can realize the automatic movement of the first guide rail to the position of different groove rollers. The sampling process is highly automated and more convenient.

[0022] In some alternative implementations, a control system is further included, which is signal-connected to the liquid extraction device to move the liquid extraction device along the first guide rail; the control system is signal-connected to the second drive member to move the first guide rail along the second guide rail.

[0023] In the above technical solution, by controlling the movement of the liquid extraction device and the first guide rail through the control system, the liquid extraction device can be automatically delivered to the location where sampling is required for automatic sampling, thereby improving the automation level of the sampling process.

[0024] Secondly, embodiments of this application provide a carbon fiber production line, including the water washing device provided in the first aspect. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] This application provides a carbon fiber production line, including a washing device. In the carbon fiber production process, the fiber bundles need to undergo a series of processing steps to finally obtain the carbon fiber product.

[0037] The washing device provided in this application embodiment is used in the washing section of a production line to clean the filament bundle 500. Specifically, as... Figure 1 and Figure 2 As shown, the washing device includes a water tank 100, the top of which has an opening for the yarn bundle 500 to pass through. A grooved roller 200 for guiding the yarn bundle 500 is provided inside the water tank 100. A liquid extraction device 300 is provided above the grooved roller 200. The liquid extraction device 300 is used to extract liquid from the water tank 100 and is configured to move along the axial direction of the grooved roller 200.

[0038] The opening at the top of the water tank 100 can completely cover the top of the water tank 100, meaning the top of the water tank 100 is a completely open opening. In the vertical direction, the projection of the opening coincides with the projection of the cavity inside the water tank 100 used to hold the cleaning fluid 110. Alternatively, the opening at the top of the water tank 100 can not completely cover the top of the water tank 100, meaning the top of the water tank 100 is not a completely open opening. In the vertical direction, the projection of the opening is located inside the projection of the cavity inside the water tank 100 used to hold the cleaning fluid 110.

[0039] The water washing device provided in this application is used in the carbon fiber production process, such as... Figure 1 As shown, the filament bundle 500 enters the water tank 100 through the opening and changes its trajectory under the action of the trough roller 200. The trough roller 200 can also press the filament bundle 500 below the surface of the cleaning liquid 110, allowing it to be immersed in the cleaning liquid 110. The extraction device 300 is positioned above the trough roller 200; that is, the extraction device 300 is at a higher position, making it less likely to be immersed in the cleaning liquid 110 or to adhere to the cleaning liquid 110 that has been splashed or carried out by the filament bundle 500, thus reducing the risk of corrosion to the extraction device 300. Since the extraction device 300 can move along the axial direction of the trough roller 200, it can move to different positions along the axial direction of the trough roller 200 for sampling, reducing the difficulty of sampling caused by the large size (width) of the water tank 100 in this direction.

[0040] In some implementations, such as Figure 2As shown, the water tank 100 is provided with a first guide rail 410, which is arranged parallel to the axial direction of the trough roller 200. The liquid extraction device 300 is disposed on the first guide rail 410 and can move along the axial direction of the first guide rail 410. The first guide rail 410 is a structure that guides the liquid extraction device 300. The first guide rail 410 can be a groove disposed on the side wall of the water tank 100 and extending along the axial direction of the trough roller 200; or it can be a rod-shaped structure disposed on the inner wall of the water tank 100 and parallel to the axial direction of the trough roller 200. By disposing the liquid extraction device 300 on the first guide rail 410, the movement of the liquid extraction device 300 can be guided, allowing the liquid extraction device 300 to move smoothly to multiple positions for sampling in a preset direction.

[0041] In other embodiments, the first guide rail 410 may not be provided in the water tank 100, but may be provided on the ground along with the water tank 100; or the first guide rail 410 may not be provided, but the liquid extraction device 300 may be suspended, and when it is necessary to use the liquid extraction device 300 for sampling, the liquid extraction device 300 may be pulled along the axial direction of the tank roller 200 to the position where sampling is required.

[0042] In some embodiments, the liquid extraction device 300 includes a first driving member and a water pump 310 slidably disposed on a first guide rail 410. The first driving member is connected to the water pump 310 to drive the water pump 310 to move along the first guide rail 410. By driving the water pump 310 to move along the first guide rail 410 by the first driving member, the water pump 310 can automatically move to the position where sampling is required under the action of the first driving member, making the operation more convenient and reducing the difficulty of sampling caused by the excessive width of the water tank 100. Furthermore, the first driving member can be disposed in the water tank 100 or in other locations.

[0043] Furthermore, in some embodiments, the pumping device 300 includes a screw and nut mechanism to drive the water pump 310 to move. In this embodiment, the first guide rail 410 is the screw in the screw and nut mechanism, and the water pump 310 is disposed in the nut of the screw and nut mechanism; the first driving member drives the first guide rail 410 to rotate, and the water pump 310 can reciprocate along the extension direction of the first guide rail 410 by the forward and reverse rotation of the first guide rail 410; wherein, the first driving member can be a motor to drive the first guide rail 410 to rotate.

[0044] In some embodiments, the first driving member may also be a mechanism such as a cylinder or hydraulic cylinder whose output motion is linear. In this embodiment, the water pump 310 is connected to the piston rod of the first driving member, and the water pump 310 moves along the first guide rail 410 during the movement of the piston rod of the first driving member.

[0045] In some implementations, such as Figure 3As shown, the inlet of the water pump 310 is connected to a first pipe 311 with its opening facing the bottom of the water tank 100. The first pipe 311 is configured to extend or retract towards or away from the bottom of the tank. The first pipe 311 is connected to the inlet of the water pump 310 and is used to extract the cleaning fluid 110 from the water tank 100 for sampling. Because the opening of the first pipe 311 faces the bottom of the tank, it is easy to extend the opening of the first pipe 311 below the surface of the cleaning fluid 110. When sampling is completed or when the water pump 310 needs to be moved, the first pipe 311 can be retracted to reduce the possibility of collision with other structures during the movement of the first pipe 311 with the water pump 310. In the embodiments of this application, the first pipe 311 can be an automatic telescopic pipe as disclosed in CN221616884U.

[0046] In other embodiments, the first conduit 311 may also be a flexible hose or a non-stretchable rigid pipe.

[0047] In some embodiments, the outlet of the water pump 310 is connected to a second pipe 312, which is used to connect to a container holding a water sample. Furthermore, the second pipe 312 is a flexible hose. It is easy to understand that when the second pipe 312 is a flexible hose, it is easy to bend, so that the end of the second pipe 312 away from the water pump 310 can be inserted into the container holding the water sample. Also, when the container holding the water sample is placed in a fixed position, the flexible second pipe 312 can adapt to the movement of the water pump 310. That is, one end of the second pipe 312 is connected to the outlet of the water pump 310, and the other end is connected to the container. During the movement of the water pump 310, the middle part of the second pipe 312 undergoes adaptive deformation. In other embodiments, the second pipe 312 can also be a rigid pipe.

[0048] In some embodiments of this application, the washing device further includes a second guide rail 420, with multiple grooved rollers 200 arranged side-by-side along the extending direction of the second guide rail 420. The second guide rail 420 is located above the grooved rollers 200, and a first guide rail 410 is slidably disposed on the second guide rail 420. The second guide rail 420 serves to guide the sliding of the first guide rail 410. The second guide rail 420 can be a groove disposed on the side wall of the water tank 100; or it can be a rod-shaped structural member connected to the water tank 100. Further, the second guide rail 420 can be connected to the water tank 100 at only two ends, or it can be connected to the water tank 100 at both ends and have one side connected to the inner wall of the water tank 100. The distances of the multiple grooved rollers 200 arranged along the extending direction of the second guide rail 420 from the bottom of the tank can be the same or different.

[0049] By sliding the first guide rail 410 onto the second guide rail 420, the first guide rail 410 can move along the extension direction of the second guide rail 420 to different positions of the groove rollers 200, facilitating the sampling of the cleaning fluid 110 at different positions of the groove rollers 200. The second guide rail 420 guides the movement of the first guide rail 410, allowing the pumping device 300 to move smoothly with the first guide rail 410 to multiple positions for sampling in a preset direction. Since the second guide rail 420 is located above the groove rollers 200, collisions are less likely to occur when the first guide rail 410 and the water pump 310 move along the extension direction of the second guide rail 420.

[0050] Furthermore, such as Figure 2 As shown, a second guide rail 420 is provided on both the inner wall of the water tank 100 and the inner wall of the opposite side. One end of the first guide rail 410 is slidably connected to one of the second guide rails 420, and the other end of the first guide rail 410 is slidably connected to the other second guide rail 420. By providing a second guide rail 420 on each of the two opposite inner walls of the water tank 100, and slidably connecting a second guide rail 420 to each end of the first guide rail 410, the force on the first guide rail 410 can be more even, and the first guide rail 410 can slide more stably.

[0051] In some embodiments, the first guide rail 410 is connected to a second driving member to drive the first guide rail 410 to move along the second guide rail 420. The second driving member may be connected to the middle of the first guide rail 410 or to one end of the first guide rail 410. There may be one, two, or more second driving members. For example, in a feasible embodiment, both ends of the first guide rail 410 are slidably disposed on the second guide rail 420, and each end of the first guide rail 410 is connected to a second driving member. By using two second driving members to drive the first guide rail 410 to slide on the second guide rail 420 from both ends, the sliding process of the first guide rail 410 can be made smoother.

[0052] In some embodiments, the second driving element can be a pneumatic cylinder or a hydraulic cylinder, and the piston rod of the second driving element is directly connected to the first guide rail 410. In other embodiments, the second guide rail 420 is the lead screw in a lead screw and nut mechanism, and the first guide rail 410 is disposed in the nut of the lead screw and nut mechanism; the second driving element is a motor, and the output shaft of the second driving element is connected to the second guide rail 420 to drive the second guide rail 420 to rotate, thereby driving the first guide rail 410 to move axially along the second guide rail 420. Using existing technologies such as pneumatic cylinders, hydraulic cylinders, or lead screw and nut mechanisms to drive the first guide rail 410 to move along the second guide rail 420 results in lower costs.

[0053] In some embodiments, the washing apparatus further includes a control system, which is signal-connected to the liquid extraction device 300 to move the liquid extraction device 300 along the first guide rail 410. The control system is also signal-connected to a second drive member to move the first guide rail 410 along the second guide rail 420. Furthermore, the control system is signal-connected to the first drive member of the liquid extraction device 300, and sends signals to the first drive member to cause the water pump 310 to reciprocate on the first guide rail 410 to sample from different positions along the axial direction of the grooved roller 200; the control system also sends signals to the second drive member to cause the first guide rail 410 to reciprocate on the second guide rail 420 to sample from different positions along the arrangement direction of the grooved roller 200.

[0054] Furthermore, the control system can also be connected to the first pipe 311 via a signal to enable the first pipe 311 to automatically extend or shorten. By shortening the first pipe 311, the possibility of the first pipe 311 colliding with other structures during the operation of the water pump 310 can be reduced; by extending the first pipe 311, the opening of the first pipe 311 can be extended below the surface of the cleaning fluid 110 for sampling.

[0055] By setting up a control system that is connected to the liquid extraction device 300 and the second drive unit, the sampling process can be automated, further reducing the risk of sampling personnel being corroded by the cleaning fluid 110.

[0056] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
