Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of impregnation setting machine, and particularly relates to an impregnation setting machine for carbon fiber tow production. BACKGROUND

[0002] The carbon fiber tow is widely applied in the fields of aerospace, automobile manufacturing, sports supplies and the like due to high strength and low density characteristics. The production of the carbon fiber tow takes polyacrylonitrile-based carbon fiber precursor as raw material and needs to go through processes of pre-oxidation, carbonization and graphitization. The impregnation setting is a core process link. The raw material tow needs to be fully immersed in a specific impregnation liquid in the impregnation setting equipment for setting operation. The impregnation time, temperature and impregnation liquid concentration are regulated and controlled to make the tow uniformly adsorb the impregnation liquid. Meanwhile, the equipment is used for guiding and setting the tow to ensure the stable shape of the tow after impregnation, to enhance the bonding force between the tow and the matrix material such as resin, and to provide a stable basis for subsequent curing and drawing processes, so as to ensure that the finished product tow has excellent and stable mechanical properties and meets the application requirements in various fields.

[0003] In the existing impregnation setting machine for carbon fiber tow production, the moving path of the raw material tow is fixed and single. Such fixed path design makes the traveling track of the tow in the impregnation pool lack of flexible adjustment space, which is easy to cause part of the tow to prematurely leave the impregnation liquid environment without being fully immersed. Due to insufficient contact time and limited contact area between the tow and the impregnation liquid, the impregnation is not thorough and the resin is not uniformly wrapped, which further adversely affects the processing quality of the subsequent curing and drawing processes, and finally may cause the mechanical properties of the finished product tow to decrease and the stability to be poor, with low practicality.

The path assembly can guide and limit the moving path of the raw material tow inside the impregnation pool, so as to ensure that the raw material tow has sufficient contact time and contact area with the impregnation liquid during the impregnation operation by extending the moving path of the raw material tow inside the impregnation pool, so as to thoroughly impregnate and uniformly wrap the resin.

[0042] The side of the lifting frame 201 and the liquid-in frame 301 is rotationally connected with a synchronous screw 3011, the synchronous screw 3011 of the lifting frame 201 is screwed in the inside of the liquid-in frame 301 on the right side, and the synchronous screw 3011 of the liquid-in frame 301 is screwed in the inside of the lifting frame 201 on the right side. In use, the moving path of the raw material filament in the impregnation tank 101 can also be adjusted, so as to control the impregnation time and moving path of the raw material filament in the impregnation tank 101, and adapt to the production and use of different types and specifications of carbon fiber filaments. The moving path of the raw material filament in the impregnation tank 101 has two adjustment modes. One is that the synchronous frame 105 is driven to move up and down by the electric push rod 104, the inside of the synchronous frame 105 is provided with a lifting groove 1051, the side of the lifting seat 202 is provided with a lifting lever 2021, the lifting lever 2021 is inserted into the inside of the lifting groove 1051, and the lifting groove 1051 can drive all lifting seats 202 to move up and down synchronously through the lifting lever 2021 when the synchronous frame 105 moves up and down (it should be noted that the height of the lower guide roller 207 needs to be lower than that of the upper guide roller 302 during the impregnation operation), so as to control the use height of the lower guide roller 207, and further change the bending angle of the raw material filament in the impregnation tank 101, i.e. the moving path during traction. The other is that the distance motor 102 is used for control, the inside of the synchronous screw 3011 is provided with a synchronous groove 3012, the middle part of the driving rod 103 is a regular polygon, the driving rod 103 is inserted into the inside of the synchronous groove 3012, and the driving rod 103 can be driven to rotate when the distance motor 102 rotates, the driving rod 103 can drive all synchronous screws 3011 to rotate through the synchronous groove 3012 when rotating, and the lifting frame 201 and the liquid-in frame 301 can be moved when the synchronous screw 3011 rotates. Since the lifting frame 201 and the liquid-in frame 301 are connected through the synchronous screw 3011, the distance between all lifting mechanisms 2 and liquid-in mechanisms 3 changes proportionally during control. The change of the distance between the lifting mechanism 2 and the liquid-in mechanism 3 also changes the bending angle of the raw material filament in the impregnation tank 101, i.e. the moving path during traction. The two modes can be used as needed or in combination.

[0043] The inside of the locking block 206 is provided with a control rod 2061, and the inside of the unlocking touch rod 205 is provided with an inclined control groove 2051, the control rod 2061 is inserted in the inside of the control groove 2051, the inside of the lifting seat 202 is provided with a locking groove 2022, when the unlocking touch rod 205 and the state block 203 are not extruded by external force, one end of the locking block 206 is inserted in the inside of the locking groove 2022, the top of the dipping pool 101 is provided with a trigger resisting plate 1011, the trigger resisting plate 1011 is located directly above the state block 203 and the unlocking touch rod 205, in use, considering that the raw material filament is passed (around) from the bottom of the lower guide roller 207, the connecting seat 204 has a locking structure, so as to ensure that the lower guide roller 207 will not be accidentally turned upward to cause the guiding function to fail due to the traction and pressure of the filament during the guiding and dipping operation of the raw material filament, and the use is stable, when the unlocking touch rod 205 and the state block 203 are not extruded by external force, the locking block 206 is inserted in the inside of the locking groove 2022 at this time, so that the state block 203 cannot move upward in the inside of the lifting seat 202, the side surface of the state block 203 is provided with a state rack 2031, and the outside of the connecting seat 204 is provided with a state gear 2041, the teeth of the state gear 2041 and the state rack 2031 are engaged and transmitted, under the tooth engagement relationship of the state gear 2041 and the state rack 2031, the connecting seat 204 and the lower guide roller 207 also cannot be turned upward, and can stably guide and support the raw material filament, and the use is stable.

[0044] The bottom of the state block 203 is provided with a reset top spring 2032, and the two ends of the reset top spring 2032 are respectively abutted against the bottom of the state block 203 and the inside of the lifting seat 202. When the state block 203 is not resisted by external force, under the action of the reset top spring 2032, the state block 203 and the lower guide roller 207 are in a horizontal state. In use, the path assembly has an avoiding function, which facilitates the layout and traction of the raw material filament between the two conveying rollers 106. When it is necessary to layout the raw material filament, the lifting seat 202 can be lifted to the topmost position by the electric push rod 104. The lifting seat 202 can drive the lower guide roller 207 to move upward synchronously when moving, and the height of the lower guide roller 207 will be higher than that of the upper guide roller 302. When the lifting seat 202 is lifted to the topmost position, the unlocking touch rod 205 is first extruded and resisted by the trigger abutting plate 1011, so that the unlocking touch rod 205 moves to the inside of the state block 203 and lengthens the locking tension spring 2052. The control groove 2051 of the unlocking touch rod 205 can drive the locking block 206 to retract into the inside of the state block 203 through the control rod 2061 when moving, that is, the locking block 206 is out of the inside of the locking groove 2022, and the locking state of the connecting seat 204 to the upward rotation is released. When the lifting seat 202 continues to move upward, the state block 203 is resisted by the trigger abutting plate 1011, so that the state block 203 moves to the inside of the lifting seat 202 and compresses the reset top spring 2032. The state rack 2031 can drive the connecting seat 204 and the lower guide roller 207 to rotate upward to avoid through the state gear 2041 when moving, so that the raw material filament is only needed to be pulled between the two conveying rollers 106 when the raw material filament is pulled and laid. When the electric push rod 104 is controlled to retract, the lower guide roller 207 will return to the horizontal state and move downward. The bottom of the lower guide roller 207 can extrude the raw material filament to lay the raw material filament between the upper guide roller 302 and the lower guide roller 207 in a zigzag manner when moving downward. The layout is fast and convenient, the operation process is simplified, and the work efficiency is improved.

[0045] The specific use and role of the embodiment are as follows: in the application, the raw material tow is arranged in the inside of the path assembly to realize the impregnation operation of the raw material tow, the raw material tow is introduced into the inside of the impregnation tank 101 from the top of the right conveying roller 106, and then is led out from the top of the left conveying roller 106 for subsequent processing operation under the guidance and leading of the path assembly, in the impregnation process, the lower guide roller 207 is located at the bottom of the upper guide roller 302, so that the raw material tow passes through the bottom of the lower guide roller 207, bypasses the top of the upper guide roller 302 and then bypasses the bottom of the next lower guide roller 207, and so on until the raw material tow is pulled out of the inside of the impregnation tank 101, the moving path of the raw material tow is arranged to be tortuous, so that the moving path and the impregnation time of the raw material tow in the inside of the impregnation tank 101 are prolonged, the raw material tow can have sufficient contact time and contact area with the impregnation liquid, the impregnation is complete and the resin is uniformly wrapped, the path assembly has an avoiding function, the raw material tow is conveniently arranged and pulled between the two conveying rollers 106, when the raw material tow needs to be arranged, the lifting seat 202 can be lifted to the topmost position through the electric push rod 104, the lifting seat 202 can drive the lower guide roller 207 to move upward synchronously when moving, and the height of the lower guide roller 207 is higher than that of the upper guide roller 302, when the lifting seat 202 is lifted to the topmost position, the unlocking touch rod 205 is first pressed and resisted by the trigger resisting plate 1011, so that the unlocking touch rod 205 moves to the inside of the state block 203 and stretches the locking tension spring 2052, the control groove 2051 of the unlocking touch rod 205 can drive the locking block 206 to retract into the inside of the state block 203 through the control rod 2061 when moving, that is, the locking block 206 is out of the inside of the locking groove 2022, and the locking state of the upward rotation of the connecting seat 204 is released, after that, when the lifting seat 202 continues to move upward, the state block 203 is resisted by the trigger resisting plate 1011, so that the state block 203 moves to the inside of the lifting seat 202 and compresses the reset top spring 2032, the state rack 2031 can drive the connecting seat 204 and the lower guide roller 207 to rotate upward and avoid through the state gear 2041 when moving, so that the raw material tow is only needed to be pulled between the two conveying rollers 106 when the raw material tow is pulled and arranged, after that, when the electric push rod 104 is controlled to retract, the lower guide roller 207 returns to the horizontal state and moves downward, the bottom of the lower guide roller 207 can arrange the raw material tow between the upper guide roller 302 and the lower guide roller 207 by pressing the raw material tow when moving downward, the arrangement is fast and convenient, and the moving path of the raw material tow in the inside of the impregnation tank 101 can also be adjusted, so that the impregnation time and the moving path of the raw material tow in the inside of the impregnation tank 101 are regulated, the production and use of different types and specifications of carbon fiber tows can be adapted, and the moving path of the raw material tow in the inside of the impregnation tank 101 has two adjustment modes, one is that the synchronous frame 105 is driven by the electric push rod 104 to move upward and downward,The lifting groove 1051 can drive all the lifting seats 202 to move up and down synchronously through the lifting lever 2021 when the synchronous frame 105 moves up and down (it should be noted that the height of the lower guide roller 207 needs to be lower than that of the upper guide roller 302 during the dipping operation of the raw material filament bundle), thereby regulating the use height of the lower guide roller 207, and changing the tortuosity angle of the raw material filament bundle inside the dipping pool 101, i.e. the movement path during traction. The second is to regulate through the spacing motor 102, which can drive the driving rod 103 to rotate when the spacing motor 102 rotates. The driving rod 103 can drive all the synchronous screws 3011 to rotate through the synchronous groove 3012 when it rotates. The synchronous screws 3011 can drive the lifting frame 201 and the liquid-in-frame 301 to move when they rotate. Since the lifting frame 201 and the liquid-in-frame 301 are connected through the synchronous screws 3011, the spacing between all the lifting mechanisms 2 and the liquid-in-mechanisms 3 changes proportionally during regulation. The change in the spacing between the lifting mechanisms 2 and the liquid-in-mechanisms 3 also changes the tortuosity angle of the raw material filament bundle inside the dipping pool 101, i.e. the movement path during traction. The two methods can be used as needed or in combination. Considering that the raw material filament bundle passes through (around) the bottom of the lower guide roller 207, the connecting seat 204 has a locking structure, thereby ensuring that the lower guide roller 207 does not rotate upward due to the traction pressure of the filament bundle during the guiding and dipping operation of the raw material filament bundle, which can cause the guiding function to fail. Stable use, when the unlocking touch rod 205 and the state block 203 are not extruded by external force, the locking block 206 is inserted into the locking groove 2022 at this time, so that the state block 203 cannot move upward in the lifting seat 202. Under the tooth engagement relationship between the state gear 2041 and the state rack 2031, the connecting seat 204 and the lower guide roller 207 cannot rotate upward, which can stably guide and support the raw material filament bundle.

[0046] In another embodiment, the rightmost lifting frame 201 is fixed inside the dipping pool 101, which can provide stable support and positioning for the left liquid-in-frame 301 and lifting frame 201 during movement and regulation, further improving the stability of the device.
