Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber filament manufacturing, in particular to a pressure roller device for carbon fiber production. Background Technique

[0002] In the spinning preparation method of carbon fiber filament manufacturing, carbon fiber is prepared by impregnating and stretching a cellulose polymer or a core / shell structured polymer into a fiber and carbonizing it under high temperature and high pressure conditions. The process principle is to dissolve or impregnate the polymer in a solution, and form a stable cellulose compound fiber by spin coating, spraying or adhering to various surfaces, and then carbonize it to make carbon fiber. Sizing agent will be added during the manufacturing process of the carbon fiber filament. The addition of the carbon fiber sizing agent can improve the wettability of the resin or coating to an ideal state, thereby improving the performance in terms of durability and shear resistance.

[0003] The sizing agent needs to be evenly coated on the surface of the carbon fiber filament. In the sizing process of the carbon fiber filament, the sizing agent is generally coated on the pressure roller, and the pressure roller contacts the surface of the guide roller around which the carbon fiber filament is wound, so that the sizing agent is coated on the outer surface of the carbon fiber filament. After the sizing agent on the surface of the pressure roller is coated on the outer surface of the guide roller where the carbon fiber filament is located for many times, it is not convenient to supplement the sizing agent on the surface of the pressure roller, resulting in the drawback that local unsized areas will appear during the subsequent process of coating the sizing agent on the outer surface of the carbon fiber filament wound on the guide roller. Therefore, this solution provides a pressure roller device for carbon fiber production. Summary of the Utility Model

Detailed implementation manner

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1-2 , the present invention provides a technical solution: a pressure roller device for carbon fiber production, including a base 1, a support frame 2 and a wire guiding roller 3. The support frames 2 are respectively fixedly installed on the left and right sides of the base 1. The wire guiding roller 3 is horizontally installed between the two support frames 2, and the bearing seats at both ends of the wire guiding roller 3 are fixed at the central bottom of the support frame 2. Among them, a wire guiding roller drive motor 4 is externally connected to the bearing seat at one end of the wire guiding roller 3. Synchronous lifting motors 5 are fixedly installed at the top ends of the two support frames 2. The bottom end of the telescopic shaft of the synchronous lifting motor 5 is connected to a coating roller bearing seat 6. A coating roller 7 is rotatably installed between the two coating roller bearing seats 6. Vertical chutes 8 are opened on the inner walls of the support frames 2. The coating roller 7 is slidably connected to the chutes 8 through a slide plate 9;

[0019] A lead screw mounting frame 10 is fixedly installed at the rear of the coating roller bearing seat 6. A horizontal lead screw 11 parallel to the coating roller 7 is passed through the lead screw mounting frame 10. The two ends of the horizontal lead screw 11 penetrate through the lead screw mounting frame 10 and extend to the outside. Among them, one end of the horizontal lead screw 11 is connected to a lead screw drive motor 12. A lead screw nut slider 13 is installed on the horizontal lead screw 11. The lead screw nut slider 13 includes a circulation channel and a number of balls that are slidably matched with the thread on the surface of the horizontal lead screw 11 inside the circulation channel;

[0020] A sponge brush 14 is installed at the bottom of the lead screw nut slider 13, and the sponge brush 14 is in contact with the outer surface of the coating roller 7. A conduit 15 is connected to the outside of the top of the lead screw nut slider 13, and the end of the conduit 15 penetrates through the lead screw nut slider 13 and is connected to the sponge brush 14.

[0021] On the outer side of the coating roller bearing block 6, a coating roller driving motor 16 is connected. The coating roller 7 is driven to rotate by the coating roller driving motor 16, so that the sizing agent on the sponge brush 14 is evenly coated on the coating roller 7, and the sizing agent on the surface of the coating roller 7 is evenly coated on the carbon fiber filaments on the surface of the wire guiding roller 3.

[0022] Two synchronous lifting motors 5 are externally connected to a PLC controller. The two synchronous lifting motors 5 synchronously drive the coating roller bearing block 6 to move up and down through the telescopic shaft; the external PLC controller synchronously controls the two synchronous lifting motors 5 to work simultaneously, and the coating roller bearing block 6 is driven to move up and down by the telescopic shaft. The outer side of the coating roller bearing block 6 is slidably connected through a sliding plate 9 and a chute 8, which plays a guiding role, realizes the horizontal up and down lifting of the coating roller 7, enables the bottom surface of the coating roller 7 to rollingly contact the surface of the wire guiding roller 3, and sizes the carbon fiber filaments wound on the wire guiding roller 3.

[0023] The lead screw driving motor 12 is a forward and reverse rotation motor, and drives the transverse lead screw 11 to rotate forward and reverse; the forward and reverse movement of the transverse lead screw 11 can drive the lead screw nut slider 13 to linearly move left and right on the transverse lead screw 11 under the cooperation of the lead screw drive. At the same time, the coating roller 7 rotates itself, so that the sponge brush 14 can evenly coat the sizing agent on different parts of the surface of the coating roller 7.

[0024] Working principle:

[0025] The transverse lead screw 11 passes through and is rotatably installed on the lead screw mounting frame 10, and the lead screw driving motor 4 arranged outside the lead screw mounting frame 10 drives the transverse lead screw 11 to perform self-rotation movement.

[0026] In the structure of this device, the wire guiding roller driving motor 4, the synchronous lifting motors 5, the lead screw driving motor 12 and the coating roller driving motor 16 are all externally connected to a power supply to work.

[0027] In the structure of this device, the wire guiding roller 3 is used to wind carbon fiber filaments, and the coating roller 7 is used to add sizing agent to the carbon fiber filaments wound on the wire guiding roller 3. The wire guiding roller 3 is driven to rotate by the wire guiding roller driving motor 4. During the process of adding sizing agent to the carbon fiber filaments wound on the wire guiding roller 3, the two synchronous lifting motors 5 work, and the bottom coating roller bearing block 6 is driven to displace downward through the telescopic shaft, so that the bottom surface of the coating roller 7 contacts the carbon fiber filaments wound on the surface of the wire guiding roller 3;

[0028] The catheter 15 is externally connected to a liquid pump containing sizing agent. The liquid pump outputs the sizing agent through the catheter 15 and penetrates to the sponge brush 14. Its lead screw driving motor 12 drives the transverse lead screw 11 to rotate forward and backward. The lead screw nut slider 11 on the transverse lead screw 11 slides under the action of the sliding fit between several ball bearings in the internal circulation channel and the thread on the surface of the transverse lead screw 11, realizing lead screw transmission, that is, the lead screw nut slider 11 linearly moves horizontally left and right on the transverse lead screw 11, so that the bottom of the sponge brush 14 contacts the outer surfaces at different positions on the left and right sides of the coating roller 7;

[0029] At the same time, the coating roller driving motor 16 drives the coating roller 7 to rotate, so that the sizing agent penetrating at the sponge brush 14 can be evenly coated on the outer surface of the coating roller 7. During this process, it can be ensured that the sizing agent on the coating roller 7 is always in a continuous supply state.

[0030] The rotating coating roller 7 can also evenly coat the sizing agent on its surface on the carbon fiber filaments on the wire guiding roller 3. The whole device structure has a continuous sizing function, avoiding the drawback that local unsized areas occur during the sizing process of the wire guiding roller 3 due to insufficient sizing agent on the surface of the coating roller 7.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
