Description

Technical Field

[0001] The utility model belongs to the technical field of carbon fiber sizing, and particularly relates to a sizing tank for reducing adhesion sediments in the process of carbon fiber sizing. Background Art

[0002] When processing carbon fiber, it is usually soaked in a sizing tank storing rubber for sizing. During the sizing process, some debris on the carbon fiber will fall off the carbon fiber and deposit inside the sizing tank to form sediment.

[0003] During the sizing process, if this part of the sediment adheres to the carbon fiber again, it will affect the sizing quality;

[0004] When the existing sizing tank is in use, in order to make the carbon fiber better immersed and glued, the carbon fiber is usually immersed in the deep part of the sizing tank. At this time, the carbon fiber and the sediment deposited at the bottom of the sizing tank are close to each other and are easily mixed together, so that the sediment adheres to the carbon fiber for the second time. Utility Model Content

[0005] The utility model aims to provide a sizing groove for reducing the adhesion of deposits during the sizing process of carbon fiber, which can increase the distance between the deposits and the carbon fiber group under the lower roller, and reduce the phenomenon of secondary adhesion of deposits during the sizing process of the carbon fiber group.

[0008] Furthermore, the vertical cross-section of the sedimentation tank is any one of a W-shape and an inverted M-shape.

[0009] Furthermore, a shaft rod is arranged inside the sediment, and a plurality of curved rods are fixedly connected to the outer side of the shaft rod.

[0010] Furthermore, the curved rod is a combination of multiple arc-shaped rods connected in sequence.

[0011] Furthermore, three shafts are mounted on the same protruding groove, the three shafts are rotatably connected inside the protruding groove, the three shafts are connected via a second transmission group, and the sizing groove also includes a driving member connected to the shaft.

[0013] The technical effects achieved by this utility model are:

[0014] The practical sizing groove for reducing the adhesion of deposits during the sizing process of carbon fibers can increase the distance between the deposits and the carbon fiber group at the bottom of the lower roller by depositing the deposits inside the raised groove, thereby reducing the re-contact between the deposits and the carbon fiber group, thereby effectively reducing the phenomenon of secondary adhesion of deposits during the sizing process of the carbon fiber group.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-2 As shown, a sizing tank for reducing adhesion deposits during carbon fiber sizing includes a sizing tank 1, both ends of the upper part of the sizing tank 1 are rotatably connected to upper rollers 2, and the lower end of the middle part of the sizing tank 1 is rotatably connected to a lower roller 3, and a carbon fiber group 4 can bypass the upper roller 2 and the lower roller 3 to perform sizing inside the sizing tank 1;

[0023] Here, the carbon fiber group 4 may be a carbon fiber cloth or a carbon fiber tow.

[0024] The core of the present technical solution is that a sedimentation trough 5 is fixedly connected to the lower side of the gluing trough 1, and a downward raised groove is arranged at the lower part of the sedimentation trough 5 at a position away from the lower roller 3 on the horizontal plane. When sediment is generated inside the gluing trough 1, it will fall under the action of gravity and fall into the inside of the raised groove. At this time, by depositing the sediment inside the raised groove, the distance between the sediment and the carbon fiber group 4 at the bottom of the lower roller 3 can be increased, thereby reducing the re-contact between the sediment and the carbon fiber group 4, thereby effectively reducing the phenomenon of secondary adhesion of the sediment during the sizing process of the carbon fiber group 4.

[0025] Among them, see Figure 2-3 The lower ends of the two raised grooves can be located in the middle position of the lower part of the raised groove, or can be located at a position away from each other at the lower ends of the two raised grooves, that is, the vertical cross-section of the sedimentation trough 5 can be any one of a W shape and an inverted M shape. At this time, the sediment will automatically fall into the lower end of the raised groove, that is, away from the lower roller 3.

[0026] See also Figure 2 and Figure 4 In order to further reduce the contact between the sediment and the carbon fiber group 4, a sediment collecting unit for collecting the sediment is provided inside the sediment. The sediment collecting unit can be a shaft rod 6 assembled inside the raised groove. A plurality of curved rods 9 are fixedly connected to the outer side of the shaft rod 6. When the thread-like sediment contacts the curved rod 9, it will be entangled on the curved rod 9.

[0027] Here, the curved rod 9 may be an arc-shaped rod, or a combination of multiple arc-shaped rods connected in sequence, and the openings of two adjacent arc-shaped rods are arranged in opposite directions.

[0028] Three shafts 6 are mounted on the same raised groove. The three shafts 6 are rotatably connected inside the raised groove. The three shafts 6 are connected through a second transmission group 8. When one of the shafts 6 rotates, it drives the other shafts 6 to rotate together.

[0029] It also includes a driving member connected to the shaft 6, which is used to input rotational kinetic energy to the shaft 6, and can be a device that outputs rotational kinetic energy such as an electric motor or a hydraulic motor;

[0030] The driving member in the present technical solution is preferably two first transmission groups 7, and one of the shaft rods 6 on the raised groove is connected to the lower roller 3 through the first transmission group 7. When the lower roller 3 rotates, the shaft rod 6 is driven to rotate through the first transmission group 7, thereby inputting rotational kinetic energy into the shaft rod 6.

[0031] Moreover, the sedimentation tank 5 is detachably fixedly connected to the lower side of the glue tank 1, and its installation method can be screw connection, clamping machine, etc., preferably screw connection. When the sediment inside the sedimentation tank 5 needs to be cleaned, the sedimentation tank 5 can be removed.

[0032] The working principle of the utility model is as follows: when sediment is generated inside the gluing groove 1, it will fall under the action of gravity and fall into the inside of the raised groove. At this time, by depositing the sediment inside the raised groove, the distance between the sediment and the carbon fiber group 4 at the lower part of the lower roller 3 can be increased, thereby reducing the re-contact between the sediment and the carbon fiber group 4, thereby effectively reducing the phenomenon of secondary adhesion of the sediment during the sizing process of the carbon fiber group 4.

[0033] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
