The output shaft of the inner transmission drive module 502 is sealed and inserted through the inner rotation drive mounting hole 1022. The rear driving pulley 503 is fixedly sleeved on the output shaft of the inner transmission drive module 502. The rear transmission belt is wound around the rear driving pulley 503 and the rear driven pulley 304. The sealing method between the output shaft of the outer transmission drive module 501 and the outer rotation drive mounting hole 1021 and the sealing method between the output shaft of the inner transmission drive module 502 and the inner rotation drive mounting hole 1022 can be achieved by combining sealing rings and other sealing members. This is a conventional technical means and will not be described in detail here.

[0042] The hydraulic balancing system 90 includes a hydraulic cylinder body 91, a piston 92, a hydraulic balancing pipe 93 and a pressure gauge 94. The upper end of the hydraulic cylinder body 91 is provided with a hydraulic input connector 95 connected to the inner cavity of the hydraulic cylinder body 91. The hydraulic input connector 95 is provided with a liquid source inlet and outlet hole 951, a liquid balance output hole 952 and a pressure gauge mounting hole 953. The liquid source inlet and outlet hole 951 is connected to an external liquid source, one end of the hydraulic balancing pipe 93 is connected to the liquid balance output hole 952, and the other end of the hydraulic balancing pipe 93 is connected to the second hydraulic balance connection hole 108. The lower end of the hydraulic cylinder body 91 is provided with the material bin connector 96 connected to the inner cavity of the hydraulic cylinder body 91. The material bin connector 96 is sealed and inserted in the first hydraulic balance connection hole 154. The piston 92 is sealed and installed in the inner cavity of the hydraulic cylinder body 91 and can move up and down. The pressure gauge 94 is fixedly mounted on the hydraulic input connector 95 , and the output end of the pressure gauge 94 is sealed and inserted into the pressure gauge mounting hole 953 .

[0043] When the forming machine with a double-rotating multi-layer mesh braiding structure of the present invention is working, the balancing liquid is injected into the balancing liquid injection hole 1085 and then sealed with a sealing plug. The liquid source inlet and outlet holes 951 are externally connected to a material extruder. The material extruder squeezes the material into the material bin 109 until the bin is full. Then the inner rotating braiding sleeve 30 and the outer rotating braiding sleeve 40 rotate at the same time. The material is squeezed into the outer material input gap 104, the middle material input gap 105 and the inner material input gap 106 at the same time, and then fills the core shaft braiding straight groove 201, the die head front braiding straight groove 70211, and the die head rear braiding straight groove 702. 21. The first braiding bevel 4021, the second braiding bevel 4022, the third braiding bevel 3021 and the fourth braiding bevel 3022 form six braided layers (the material is extruded through the front braiding straight groove 70211 of the die and the rear braiding straight groove 70221 of the die to form the outermost braided layer, which is counted as one layer). Finally, the material is output from the material output gap 107, and the rear end of the center hole of the core shaft 20 is connected to a high-pressure gas source. The high-pressure gas source blows directly through the center hole of the core shaft 20 and blows into the center hole of the output finished product, so that the finished product floats in the air instead of falling, thereby ensuring the molding quality of the finished product. During the material extrusion molding process, the hydraulic balance system 90 adjusts the pressure difference between the material bin 109 and the hydraulic balance chamber in real time according to the extrusion pressure and balances the pressure between the material bin 109 and the hydraulic balance chamber to avoid the loosening or deformation of related components due to the impact of excessive pressure in the material bin. That is, when the pressure of the material in the material bin 109 increases, the material presses against the piston 92, causing the piston 92 to move upward, overcoming the pressure in the hydraulic balance chamber, until the pressure of the material in the material bin 109 and the pressure in the hydraulic balance chamber are balanced. All of the above-mentioned related actions can be automatically controlled by the control system.

[0044] The forming machine with a double-rotating multi-layer mesh braiding structure of the utility model can form six braided layers on the finished product, greatly increasing the overall strength of the finished casing, effectively avoiding the situation of knots and breakage, and making the finished casing better in quality.

[0045] It should be noted that the rotary drive assembly can also be configured as a rotary drive mounting hole and a transmission drive module, the output shaft seal of the transmission drive module is inserted through the rotary drive mounting hole, and the front driving pulley 503 and the rear driving pulley 504 are sequentially fixed on the output shaft of the transmission drive module from front to back. The second hydraulic balance connection hole 108 and the balance liquid injection hole 1085 can also be opened on the front fixed machine base 15, and the second hydraulic balance connection hole 108 and the balance liquid injection hole 1085 are connected to the front mounting cavity 151. The die head socket braiding straight groove can also be opened solely on the inner wall of the rotary sleeve insertion hole 7022 or solely on the inner wall of the core shaft insertion hole 7021 facing the rear of the material output gap 107.
