Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber cloth production, in particular to a device for evenly distributing carbon fiber tows. Background Art

[0002] During the production of carbon fiber prepreg, it is necessary to coat epoxy resin on the carbon fiber tows to bond the tows together to form carbon fiber cloth. When the carbon fiber tows are coated with glue, due to the adhesive force of the epoxy resin, the tows are likely to be unevenly distributed. In some positions, the glue amount is large and the tows are densely distributed, while in some positions, the glue amount is small and the tows are sparsely distributed. In addition, there may be bubbles remaining in the epoxy resin, resulting in poor bonding effect of the carbon fiber tows, affecting the density of the carbon fiber cloth, and ultimately affecting the finished product quality of the carbon fiber cloth. Content of the Utility Model

[0003] To solve the above technical problems, the utility model discloses a device for evenly distributing carbon fiber tows, which includes a frame, a feeding roller, a discharging roller, a bracket, a vibrating plate and a vibrating motor. The feeding roller and the discharging roller are respectively arranged at both ends of the frame through a first roller bracket and a second roller bracket. The bracket is arranged on the frame between the feeding roller and the discharging roller. The bottom of the vibrating plate is arranged above the bracket through a damping pad, and the vibrating motor is arranged at the bottom of the vibrating plate.

[0004] Further, both the front and rear ends of the vibrating plate are arc-shaped structures.

[0005] Further, a baffle is provided on each of the left and right sides of the vibrating plate.

[0006] Further, a glue receiving box is provided at the bottom of the frame above the front and rear ends of the vibrating plate.

A buffer spring is arranged in the chute, and both ends of the buffer spring are respectively connected to the top of the chute and the top of the slider.

[0008] Further, a drying mechanism is further provided on the outer side of the discharging roller. The drying mechanism includes a housing and a plurality of heating tubes. The housing is arranged on the frame through a support rod. Feed ports and discharge ports are respectively arranged at both ends of the housing, and the plurality of heating tubes are evenly arranged on the upper and lower sides inside the housing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments.

[0019] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0020] In addition, the descriptions involving "first", "second", etc. in the present utility model are for descriptive purposes only, and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0021] In the description of the embodiments, unless otherwise clearly specified and defined, terms such as "arranged" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or connected through an intermediate medium, or there may be a communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] As Figure 1-2 shown, the uniform distribution device for carbon fiber tows in this embodiment includes a frame 1, a feed roller 2, a discharge roller 3, a bracket 4, a vibrating plate 5, and a vibrating motor 6. The feed roller 2 and the discharge roller 3 are respectively arranged at both ends of the frame 1 through a first roller bracket 7 and a second roller bracket 8. The bracket 4 is arranged on the frame 1 between the feed roller 2 and the discharge roller 3. The bottom of the vibrating plate 5 is arranged above the bracket 4 through a vibration damping pad 9. The vibrating motor 6 is arranged at the bottom of the vibrating plate 5.

[0023] Under the traction of the traction device, the carbon fiber tow winds around the vibrating plate 5 from the bottom of the feed roller 2 and then winds out from the bottom of the discharge roller 3. When the carbon fiber tow passes through the vibrating plate 5, the vibrating motor 6 drives the vibrating plate 5 to vibrate at a high frequency, causing the carbon fiber tow passing above it to also vibrate at a high frequency, thereby evenly spreading the epoxy resin on the surface of the tow and eliminating the air bubbles therein, so that the tow is evenly distributed, preventing the phenomenon of uneven density, and thus improving the finished product quality of the carbon fiber cloth.

[0024] The vibration damping pad 9 can be a rubber pad or a silica gel pad, which can effectively reduce the vibration transmitted to the bracket 4 and the frame 1, thereby reducing the working noise of the device.

[0025] Both the front and rear ends of the vibrating plate 5 are arc-shaped structures, which are beneficial to the smooth transition of the carbon fiber tow and prevent it from being scratched. A baffle 10 is provided on each of the left and right sides of the vibrating plate 5 to play a role in guiding the carbon fiber tow.

[0026] Below the vibrating plate 5 at the front and rear ends above the frame 1, a glue receiving box 11 is respectively provided for receiving the epoxy resin dripping during the vibration.

[0027] A chute 12 is longitudinally formed on the first roller frame 7. Both ends of the feeding roller 2 are arranged in the chute 12 through sliders 13. A buffer spring 14 is arranged in the chute 12, and both ends of the buffer spring 14 are respectively connected to the top of the chute 12 and the top of the slider 13. The buffer spring 14 forms a movable connection between the feeding roller 2 and the first roller frame 7, enabling the feeding roller 2 to move up and down along the first roller frame 7 under the action of an external force, and preventing the carbon fiber tow from being pulled or broken due to uneven force during traction and vibration.

[0028] A drying mechanism is further arranged on the outer side of the discharging roller 3, such as Figure 3 shown. The drying mechanism includes a housing 15 and a plurality of heating tubes 16. The housing 15 is arranged on the frame 1 through a support rod 17. An inlet 18 and an outlet 19 are respectively arranged at both ends of the housing 15. The plurality of heating tubes 16 are uniformly arranged on the upper and lower sides inside the housing 15. Under the action of the heating tubes 16, the epoxy resin on the surface of the carbon fiber tow can be quickly dried, preventing the epoxy resin from flowing or dripping again.

[0029] Two guiding rollers 20 arranged opposite to each other up and down are further arranged on the outer side of the drying mechanism. The two guiding rollers 20 are arranged on the frame 1 through a third bracket 21. The dried carbon fiber tow is conveyed out between the two guiding rollers 20.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it; when the combination of the technical solutions appears to be contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
