[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] According to the embodiment of the utility model, a double-station needling machine is provided. Figures 1 to 4 , including: a double-station mold 1, the double-station mold 1 is used to fit the preform, the double-station mold 1 includes a connecting shaft 11, and the connecting shaft 11 extends along the rotation axis of the double-station mold 1; a needling mechanism 2, used to needling the preform; a supporting mechanism 3, the supporting mechanism 3 is used to support the double-station mold 1, the supporting mechanism 3 includes a fixing device 4, the fixing device 4 includes a first fixing block 41 and a second fixing block 42 arranged oppositely, the first fixing block 41 includes a first fixing groove 411, the second fixing block 42 includes a second fixing groove 421, the first fixing groove 411 and the second fixing groove 421 contain the connecting shaft 11, and the first fixing block 41 and the second fixing block 42 are movably connected; a discharging mechanism 5, the discharging mechanism 5 is relatively movably connected to the supporting mechanism 3, and the discharging mechanism 5 is used to move the supporting mechanism 3 outside the frame of the double-station needling machine.

[0027] By setting the fixing device 4 and the discharging mechanism 5, the first fixing groove 411 and the second fixing groove 421 can be used to support the connecting shaft 11. After the first fixing block 41 and the second fixing block 42 are separated, the double-station mold 1 can be loaded or unloaded, and the supporting mechanism 3 can be moved outside the frame of the double-station needling machine to facilitate the unloading of the double-station mold 1. By adopting the double-station needling machine of this embodiment, two products can be made at the same time in one process. Compared with the traditional single needling machine, the production efficiency of the preform is improved, the installation space of the equipment is saved, and the technical problem of low production efficiency of the needling machine in the related art is solved.

[0028] The double-station needling machine of this embodiment adopts a double-station mold, and can make two preforms at the same time. Specifically, when bonding the carbon fiber cloth and the carbon fiber, the two products are not distinguished, but the cloth is laid together according to the mold size. When the whole preform is needling completed, the whole preform containing the two products is removed, and then the whole preform is cut apart to finally become two products.

[0029] Specifically, the double-station mold in this embodiment is longer than the single-station mold, so the discharge method of the original single-station needling machine is not suitable for the double-station mold. The double-station needling machine in this embodiment is used to move the support mechanism 3 outside the frame through the discharge mechanism 5, and then separate the first fixed block 41 and the second fixed block 42, so that the double-station mold 1 is in an unfixed state. At this time, the double-station mold 1 can be directly transferred to the next process.

[0030] In the double-station needle loom of this embodiment, see Figure 2The fixing device 4 includes: a rotating pin 43, which is connected to the first fixing block 41 and the second fixing block 42 respectively, and the first fixing block 41 and the second fixing block 42 are relatively rotatably connected through the rotating pin 43; a locking rod 44, which is relatively rotatably connected to the first fixing block 41, and the second fixing block 42 includes a locking groove 422 for the locking rod 44 to penetrate. Through the above arrangement, when the locking rod 44 is inserted into the locking groove 422, the locking rod 44 blocks the second fixing block 42 from rotating in a direction away from the first fixing block 41, and the double-station mold is fixed at this time. When the locking rod 44 leaves the locking groove 422, the second fixing block 42 can rotate in a direction away from the first fixing block 41, and the double-station mold becomes an unfixed state.

[0031] Specifically, the rotating pin 43 and the locking rod 44 are respectively located at two ends of the fixing device 4 .

[0032] In the double-station needle loom of this embodiment, see Figure 2 The second fixing block 42 includes a first limiting plate 423 and a second limiting plate 424 arranged at intervals, and a locking groove 422 is formed between the first limiting plate 423 and the second limiting plate 424. Specifically, the locking groove 422 is an open groove, which is convenient for the locking rod 44 to enter or leave.

[0033] In the double-station needle loom of this embodiment, see Figure 2 The fixing device 4 includes a locking block 45, the locking block 45 includes a connection hole for the locking rod 44 to penetrate, and the locking block 45 is relatively movably connected to the locking rod 44. By providing the locking block 45, when the locking block 45 is penetrated on the locking rod 44, the locking block 45 and the second fixing block 42 abut against each other, thereby preventing the second fixing block 42 from rotating in a direction away from the first fixing block 41.

[0034] Preferably, the locking block 45 is a nut, and the locking rod 44 is a screw rod.

[0035] In the double-station needle loom of this embodiment, see Figure 1 The supporting mechanism 3 includes: a mounting platform 31, a fixing device 4 is fixedly arranged on the mounting platform 31; and a lifting device 32, which is used to support the mounting platform 31 and can control the mounting platform 31 to move along the height direction. Through the above arrangement, the relative height between the double-station mold and the needling mechanism 2 can be adjusted, thereby adjusting the depth of the needles penetrating the preform.

[0036] In the double-station needle loom of this embodiment, see Figure 1The lifting device 32 includes: a synchronous lifter 321, which includes a plurality of lifting rods 322, and the lifting rods 322 are all connected to the installation platform 31; and a driving motor, which is used to drive the synchronous lifter 321. By setting the synchronous lifter 321, the synchronous lifter 321 can make the plurality of lifting rods 322 rise and fall at the same time, so that the lifting height of the entire installation platform 31 is unified, so that the depth of the needle penetrating into the preform is unified, and the thickness of the preform is uniform, so as to ensure the product quality of the preform. In addition, by using the synchronous lifter 321, the equipment structure is simplified and the installation space of the equipment is reduced.

[0037] In the double-station needle loom of this embodiment, see Figure 1 The mounting platform 31 includes a first mounting platform 311 and a second mounting platform 312, which are respectively located on both sides of the double-station mold 1, and a fixing device 4 is installed on the first mounting platform 311 and the second mounting platform 312. Through the above arrangement, it is ensured that the mounting platform 31 can stably support the double-station mold 1.

[0038] In the double-station needle loom of this embodiment, see Figure 1 The double-station needling machine includes a power mechanism 6, which is fixedly arranged on the first mounting platform 311, and the output shaft of the power mechanism 6 is drivingly connected to the connecting shaft 11. Through the above arrangement, the double-station mold 1 is driven to rotate by the power mechanism 6.

[0039] In the double-station needle loom of this embodiment, see Figure 1 The discharging mechanism 5 includes: a pulley 51, which is fixedly arranged with the supporting mechanism 3; a slide rail 52, which is slidably connected with the pulley 51, and the extending direction of the slide rail 52 is parallel to the extending direction of the connecting shaft 11; and a sliding motor, which is used to drive the pulley 51 to rotate. Specifically, the pulley 51 is fixedly connected with the bottom of the supporting mechanism 3, and the pulley 51 can drive the supporting mechanism 3 to reciprocate along the slide rail 52, thereby realizing the loading and unloading of the preform.

[0040] In the double-station needle loom of this embodiment, see Figure 1 The acupuncture mechanism 2 includes a cam structure 21 for driving the acupuncture needle to move up and down and a rotating shaft 22 connected to the cam structure 21 . The acupuncture mechanism 2 includes a plurality of bearing seats 23 fixedly arranged on the frame, and the rotating shaft 22 is connected to the plurality of bearing seats 23 .

[0041] Specifically, the cam structure 21 can be driven to rotate by rotating the rotating shaft 22, so that the cam structure 21 drives the needle to move up and down to realize the acupuncture action. Since the length of the double-station mold is lengthened, the length of the rotating shaft 22 is also adjusted accordingly, and the number of bearing seats 23 is increased to support the rotating shaft 22 more stably.

[0042] Preferably, there are two cam structures 21 and three bearing seats 23 , and the three bearing seats 23 and the two cam structures 21 are distributed on the rotating shaft 22 in a cross-spaced manner.
