For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] like Figures 1 to 9 Shown: A double-disc carbon fiber warp knitting machine, comprising:

[0040] The base assembly 1 includes a first mounting plate 11 and a second mounting plate 12 vertically arranged on a working surface, the first mounting plate 11 and the second mounting plate 12 are arranged in parallel, and a receiving space 13 is formed between the first mounting plate 11 and the second mounting plate 12;

[0041] The double-pan head assembly 2 is arranged in the accommodating space 13, and the two ends of the double-pan head assembly 2 are respectively arranged on the first mounting plate 11 and the second mounting plate 12. The double-pan head assembly 2 includes a first gas expansion shaft 21, a second gas expansion shaft 22, a rotating frame 23 and a first rotating shaft 24. The first gas expansion shaft 21 is sleeved with the first pan head 01, the second gas expansion shaft 22 is sleeved with the second pan head 02, and the first gas expansion shaft 21 and the second gas expansion shaft 22 are arranged on the rotating frame 23; one end of the first rotating shaft 24 is arranged on the rotating frame 23, and the other end is arranged in the first mounting plate 11 or the second mounting plate 12;

[0042] The driving component 3 is arranged in the first mounting plate 11 and the second mounting plate 12, and includes a first driving member 31, a second driving member 32 and a third driving member 33. The first driving member 31 drives the first air expansion shaft 21 to rotate, the second driving member 32 drives the second air expansion shaft 22 to rotate, and the third driving member 33 drives the rotating frame 23 to rotate along the axis of the first rotating shaft 24.

[0043] By setting a base assembly 1, a double disc head assembly 2 and a driving assembly 3, the double disc head assembly 2 includes a rotating frame 23 with two ends arranged on the first mounting plate 11 and the second mounting plate 12, and a first gas expansion shaft 21 and a second gas expansion shaft 22 are provided on the rotating frame 23 in parallel, a first disc head 01 is sleeved on the first gas expansion shaft 21, and a second disc head 02 is provided on the second gas expansion shaft 22, and the first disc head 01 and the second disc head 02 are used to carry the unwinding barrel. When working, the first driving member 31 drives the first gas expansion shaft 21 to rotate, driving the first disc head 01 to rotate. When the material on the unwinding barrel on the first disc head 01 is used up, the third driving member 33 drives the rotating frame 23 to rotate to a suitable angle, and the second driving member 32 drives the second gas expansion shaft 22 to rotate, driving the second disc head 02 to rotate, and the unwinding barrel of the second disc head 02 quickly enters the working state, and the double disc heads perform rapid material change, and the material change switching time is short, which can meet the rapid replacement of the unwinding disc head, reduce the waiting time for production material change, and improve production efficiency.

[0044] The first driving member 31, the second driving member 32 and the third driving member 33 are all provided with a reducer 4, and the reducer 4 drives the first air inflation shaft 21 or the second air inflation shaft 22 to rotate for unwinding, and the first air inflation shaft 21 drives the first disc head 01 or the second air inflation shaft 22 drives the second disc head 02 to rotate, thereby realizing the unwinding operation. We can control the unwinding speed by adjusting the speed of the servo motor, that is, we can also adjust the tension of the yarn during the unwinding process by adjusting the speed of the servo motor.

[0045] The present invention can also adjust the tension of the yarn in another way: the diameter of the unwinding barrel of the first disc head 01 or the second disc head 02 can be monitored in real time (calculated in real time according to the running speed and time), so that when the yarn of the first disc head 01 or the second disc head 02 is released, the angle of the double disc head assembly 2 is rotated in real time to keep a fixed angle between the barrel yarn and the roller assembly 5, so as to ensure the consistency of the yarn tension, improve the accuracy of laying the weft yarn, and further improve the quality of the finished product.

[0046] As a preferred embodiment of the above, the rotating frame 23 includes rotating plates 231 at both ends, the end surface of the rotating plate 231 is a cross-shaped structure, including a first connecting end 231a and a second connecting end 231b perpendicular to each other, the two first connecting ends 231a are respectively provided with a first gas expansion shaft 21 and a second gas expansion shaft 22, and the two second connecting ends 231b are provided with two cross bars 232. Specifically, the cross bar 232 is used to connect the rotating plates 231 at both ends, increase the stability of the rotating frame, help ensure that the structure of the entire machine will not be unstable due to vibration during operation, and improve the reliability of the equipment.

[0047] The end face of the rotating plate 231 is a cross-shaped structure. On the one hand, the weight of the entire rotating frame 23 can be reduced, and the lightweight design helps to reduce the inertia of the rotating frame 23. On the other hand, during installation, the first disk head 01 and the second disk head 02 are respectively installed on the first connecting ends 231a of the two rotating plates 231, and then the cross bar 232 is installed on the second connecting end 231b. The cross bar 232 has a tightening effect on the rotating plates 231 on both sides. The relatively simple structure of the cross bar 232 connection design makes the maintenance and disassembly process more convenient, thereby improving the maintainability of the equipment.

[0048] In this embodiment, a plurality of through holes 231c are provided on the rotating plate 231 to further reduce the overall mass of the rotating frame 23. The lightweight design helps to reduce the inertia of the device, reduce the impact of the mass of the moving parts on the system dynamics, and improve the dynamic response speed of the device.

[0049] Among them, the first rotating shaft 24 includes a shaft head 241 and a shaft body 242, the shaft head 241 passes through the rotating plate 231, and the shaft body 242 is partially arranged in the first mounting plate 11 or the second mounting plate 12, the shaft head 241 and the shaft body 242 are detachably connected. Specifically, the detachable shaft head 241 is easy to maintain, and the detachable shaft head 241 allows for quick disassembly and replacement of the double disc head assembly 2. When the barrels on the first disc head 01 and the second disc head 02 on the first gas expansion shaft 21 and the second gas expansion shaft 22 are used up, the double disc head assembly 2 needs to be removed, and the first disc head 01 and the second disc head 02 need to be replaced with new disc head barrels. The shaft head 241 and the shaft body 242 are detachably connected, making the maintenance process more convenient without the need to disassemble the entire first rotating shaft 24, which helps to reduce maintenance time and improve production efficiency.

[0050] As a preferred embodiment of the above embodiment, a flange 241a is provided at one end of the shaft head 241, and a boss 241b is provided at the other end. The boss 241b is inserted into the end of the shaft body 242 for positioning and installation, which is convenient for rapid insertion and positioning, reduces assembly errors, improves production efficiency, ensures the coaxiality of the shaft head 241 and the shaft body 242, and improves the stability and accuracy of the machine. The flange 241a is provided with a first fixing member 243 and a second fixing member 244. The first fixing member 243 is used to fix the flange 241a on the rotating plate 231, and the second fixing member 244 is used to fix the shaft head 241 It is connected to the shaft body 242; the design of the first fixing piece 243 and the second fixing piece 244 strengthens the stability of the connection. The double-disk head assembly 2 can be removed by simply removing the second fixing piece 244, which facilitates the replacement of the first disk head 01 and the second disk head 02 on the first gas expansion shaft 21 and the second gas expansion shaft 22. Similarly, it is only necessary to insert the flange 241a on the shaft head 241 into the end of the shaft body 242 and lock the second fixing piece 244 to complete the insertion of the double-head assembly, which can meet the needs of rapid replacement of the unwinding disk head, reduce the waiting time for production material change, and improve the actual start-up production efficiency.

[0051] In this embodiment, a positioning groove 241c is provided on the side of the convex edge 241a, and a groove 231d is provided on the rotating plate 231. A positioning block 231e is provided in the groove 231d, and the positioning block 231e is arranged in the positioning groove 241c; the arrangement of the positioning block 231e and the positioning groove 241c, on the one hand, facilitates the alignment of the mounting hole on the shaft head 241 with the mounting hole on the shaft body 242 when the shaft head 241 is installed with the shaft body 242, and the mounting hole on the shaft head 241 is aligned with the mounting holes of the first mounting plate 11 and the second mounting plate 12. The first and second fixing members 243 and 244 are aligned, thereby simplifying the installation process, reducing the need for alignment and adjustment, and improving installation efficiency; it is convenient for the subsequent installation of the first fixing member 243 and the second fixing member 244, saving disassembly and assembly time and improving installation efficiency; on the other hand, the setting of the positioning block 231e and the positioning groove 241c can radially position the shaft head 241 with the rotating plate 231, so that when the first rotating shaft 24 rotates, it drives the rotating plate 231 to rotate, thereby completing the material replacement of the first disc head 01 and the second disc head 02, and increasing the stability and accuracy of the operation.
