[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0042] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0043] In existing technologies, the carbon fiber needs to be cut to obtain the required length during the molding process of carbon fiber composites. However, during the cutting process, because the carbon fiber is in bundle form, the cut carbon fiber is prone to scattering, making it difficult to collect.
[0044] To address the aforementioned technical problems, this invention provides a carbon fiber cutting system. A curing device and a first conveying device are sequentially arranged along the travel direction of the carbon fiber bundle. A cutting device is located at the output end of the first conveying device. Thus, before the carbon fiber bundle is cut by the cutting device, it is first cured by the curing device. This prevents the cured carbon fiber bundle from scattering, improving its cohesiveness and preventing it from dispersing after cutting, thereby reducing the difficulty of collecting the carbon fiber bundle. Simultaneously, a limiting device is provided between the cutting device and the curing device. The limiting device is located on the first conveying device and has a conveying space between it and the first conveying device. This conveying space can limit the movement of the carbon fiber bundle, preventing it from deviating from the first conveying device during transport and thus avoiding situations where the carbon fiber bundle cannot be cut by the cutting device, thereby improving the reliability of the carbon fiber cutting system.
[0045] The carbon fiber cutting system provided according to this utility model will now be described in detail with reference to the accompanying drawings.
[0046] like Figure 1 As shown, an exemplary embodiment of this utility model provides a carbon fiber cutting system, which includes a curing device 10, a first conveying device 20, a cutting device 30, and a limiting device 110. The curing device 10 is used to cure carbon fiber tows. The first conveying device 20 is disposed downstream of the curing device 10 along the traveling direction of the carbon fiber tow, and is used to convey the carbon fiber tow cured by the curing device 10. The cutting device 30 is disposed at the output end of the first conveying device 20. Exemplarily, the first conveying device 20 has an input end. The cured carbon fiber tow is conveyed to the first conveying device 20 through the input end, and then conveyed towards the output end of the first conveying device 20. The cutting device 30 disposed at the output end of the first conveying device 20 cuts the carbon fiber tow conveyed to the output end of the first conveying device 20. This design allows the carbon fiber bundles to be cured by a curing device before being cut by the cutting device. This makes the cured carbon fiber bundles less likely to scatter, improves the bundle's cohesion, and prevents the cut carbon fiber bundles from scattering, thereby reducing the difficulty of collecting the carbon fiber bundles.
[0047] A limiting device 110 is disposed on the first conveying device 20 and located between the cutting device 30 and the curing device 10. A conveying space is provided between the limiting device 110 and the first conveying device 20 for the passage of carbon fiber filaments, meaning that at least a portion of the carbon fiber filaments on the first conveying device 20 pass through the conveying space. This prevents the carbon fiber filaments from deviating from the first conveying device 20 during the conveying process, thus avoiding situations where they cannot be cut by the cutting device, thereby improving the reliability of the carbon fiber cutting system.
[0048] In one embodiment, the first conveying device 20 includes a conveyor belt 21 and a first drive motor 22. The conveyor belt 21 is used to convey carbon fiber bundles, and a limiting device 110 is disposed on the conveyor belt 21. The first drive motor 22 is driven and connected to the conveyor belt 21. Exemplarily, the first drive motor 22 is electrically connected to the conveyor belt 21, thereby driving the conveyor belt 21 to run.
[0049] In this embodiment, the conveyor belt is driven by the first drive motor, which brings the carbon fiber bundles close to the cutting device for cutting without human intervention, thus improving the reliability of the carbon fiber cutting system. Furthermore, the simple structure of the conveyor belt and the first drive motor reduces the complexity of the carbon fiber cutting system.
[0050] In one embodiment, the limiting device 110 includes a limiting roller 111 and a second drive motor 112. The limiting roller 111 is disposed on the conveyor belt 21, and the axial direction of the limiting roller 111 is set at an angle to the traveling direction of the carbon fiber bundle, forming a conveying space between the limiting roller 111 and the conveyor belt 21. The second drive motor 112 is driven and connected to the limiting roller 111. Exemplarily, the angle can be 45 degrees, 60 degrees, 90 degrees, etc. The distance between the limiting roller 111 and the conveyor belt 21 can be adjusted as needed to accommodate carbon fiber bundles of different specifications.
[0051] In this embodiment, a conveying space is formed between the limiting roller and the conveyor belt, which simplifies the structure of the limiting device and facilitates production and processing. Furthermore, by driving the limiting roller to rotate via a second drive motor, the thrust applied by the limiting roller to the carbon fiber bundle is aligned with the conveying direction of the carbon fiber bundle. This accelerates the conveying speed of the carbon fiber bundle, thereby improving the efficiency of the carbon fiber cutting system.
[0052] In one embodiment, the curing device 10 includes a housing, a first spraying device, and a second spraying device. The housing has an accommodating space, and the housing has an inlet and an outlet communicating with the accommodating space. The first spraying device is disposed on a first inner wall within the accommodating space and is used to spray curing agent along a first direction. The second spraying device is disposed on a second inner wall within the accommodating space, opposite to the first inner wall, and is used to spray curing agent along a second direction, where the first and second directions are different. For example, the first inner wall may be the top inner wall of the accommodating space, and the second inner wall may be the bottom inner wall of the accommodating space. The first direction is the direction from the first inner wall to the second inner wall, i.e., a downward direction when spraying curing agent. The second direction is the direction from the second inner wall to the first inner wall, i.e., an upward direction when spraying curing agent.
[0053] In this embodiment, the uncured carbon fiber tow enters the accommodating space through the inlet of the outer shell. Within the accommodating space, a curing agent is sprayed onto the carbon fiber tow using a first spraying device and a second spraying device to cure it. This improves the comprehensiveness of the curing agent application to the carbon fiber tow, thereby effectively enhancing the curing effect. The cured carbon fiber tow is then conveyed to the first conveying device through the outlet to be cut by the cutting device, thus improving the reliability of the carbon fiber cutting system.
[0054] In one embodiment, the cutting device 30 includes a third drive motor 31 and a cutting blade 32. The cutting blade 32 is drivenly connected to the output shaft of the third drive motor 31. The third drive motor 31 is fixed to the output end of the first conveying device 20, and the axial direction of the output shaft of the third drive motor 31 is set at an angle to the traveling direction of the carbon fiber bundle. The angle is, for example, 90 degrees, 75 degrees, etc., thus ensuring that the cutting blade can cut the carbon fiber bundle when rotating.
[0055] In this embodiment, the cutting blade is driven by a third drive motor, which enables the cutting blade to rotate and cut carbon fiber bundles, thereby improving the efficiency of the cutting blade in cutting carbon fiber bundles.
[0056] For example, the distance between the limiting roller 111 and the cutting blade 32 can be 5 to 10 cm, and the cutting blade 32 can be a cross-shaped blade.
[0057] In one embodiment, the carbon fiber cutting system further includes a drying device 40, which is disposed between the curing device 10 and the first conveying device 20. The drying device 40 is used to dry the carbon fiber bundles cured by the curing device 10.
[0058] In this embodiment, when the cured carbon fiber bundles are not dried, cutting them can easily result in problems such as the cut carbon fiber bundles sticking to the cutting device, uneven cuts, and carbon fiber filament pulling. By setting up a drying device to dry the cured carbon fiber bundles, the cutting efficiency and the quality of the cut carbon fiber bundles are improved.
[0059] For example, the drying device 40 may include a drying chamber, drying equipment, etc. The drying device 40 may be provided with an inlet and an outlet. The cured carbon fiber tow can be dried through the inlet, and the dried carbon fiber tow can be conveyed to the first conveying device through the outlet.
[0060] In one embodiment, the carbon fiber cutting system further includes a second conveying device 50 and a third conveying device 60. The second conveying device 50 is disposed between the curing device 10 and the drying device 40, and is used to convey the cured carbon fiber tow to the drying device 40. The third conveying device 60 is disposed between the drying device 40 and the first conveying device 20, and is used to convey the dried carbon fiber tow to the first conveying device 20.
[0061] In this embodiment, after the curing device cures the carbon fiber bundle, the cured carbon fiber bundle enters the drying device for drying under the action of the second conveying device. The dried carbon fiber bundle is then conveyed to the first conveying device by the third conveying device to be cut by the cutting device. In this way, the conveying efficiency of the carbon fiber bundle can be effectively improved, thereby improving the cutting efficiency and reliability of the carbon fiber cutting system.
[0062] For example, both the second conveying device 50 and the third conveying device 60 may include a drive motor and a drive roller, with the drive motor driving the drive roller to rotate in order to transmit the carbon fiber bundle.
[0063] In one embodiment, the carbon fiber cutting system further includes a fiber unwinding device 70 and a fourth conveying device 80. The fiber unwinding device 70 is disposed upstream of the curing device 10 along the travel direction of the carbon fiber bundle, and is used to hold the yarn bobbin wound with the carbon fiber bundle. Exemplarily, the fiber unwinding device 70 may include a fiber unwinding frame.
[0064] A fourth conveying device 80 is disposed between the unwinding device 70 and the curing device 10. The fourth conveying device 80 is used to convey the carbon fiber tow on the unwinding device 70 to the curing device 10. Exemplarily, the fourth conveying device 80 may include a drive motor and a drive roller, and the drive motor drives the drive roller to rotate in order to transmit the carbon fiber tow.
[0065] In this embodiment, when the fourth conveying device is running, the carbon fiber bundles on the unwinding device can enter the curing device for curing through the fourth conveying device, thereby improving the convenience of unwinding the carbon fiber bundles.
[0066] In one embodiment, the carbon fiber cutting system further includes a fiber splitting device 90, which is disposed between the fiber unwinding device 70 and the fourth conveying device 80. The fiber splitting device 90 is used to disperse the carbon fiber bundle. Exemplarily, the fiber splitting device 90 can be a comb-like structure, and the spacing between the comb teeth can be 1 cm, 2 cm, 3 cm, etc.
[0067] In this embodiment, since the carbon fiber bundles in the unwinding device are usually wound in multiple bundles, direct transmission can easily lead to entanglement between the carbon fiber bundles. By setting up a fiber separating device to separate the carbon fiber bundles, mutual interference is avoided, thereby improving the reliability of the carbon fiber cutting system.
[0068] In one embodiment, the carbon fiber cutting system further includes a collecting device 100 disposed below the cutting device, the collecting device 100 being used to collect the cut carbon fiber bundles. Exemplarily, the collecting device 100 may be, for example, a box.
[0069] In this embodiment, by setting up a collection device, the cut carbon fiber bundles will fall into the collection device under the action of gravity, thereby further reducing the difficulty of collecting carbon fiber bundles.
[0070] The embodiments described in this specification are merely examples of implementations of the inventive concept. The scope of protection of this utility model should not be considered as limited to the specific forms described in the embodiments. The scope of protection of this utility model also includes equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
