Specific implementation mode
[0027] In order to make the purpose, technical solution and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0028] In one embodiment, as Figures 1-4 shown, the self-locking gear structure for the three-roller head of the roving frame includes: a support frame 100, a mounting hole 200, a roller head 300, a slider 400 and a self-locking component. A number of mounting holes 200 are opened on the side of the support frame 100; a number of the roller heads 300 are all arranged in the mounting holes 200; a number of the sliders 400 are arranged inside the support frame 100; the self-locking component includes a ratchet wheel 501, the ratchet wheel 501 is arranged on the outer surface of one end of the roller head 300, a rotating column 502 is arranged on the side of the slider 400 close to the ratchet wheel 501, a pawl 503 is rotatably connected to the outer surface of the rotating column 502, the pawl 503 and the ratchet wheel 501 are in mutual contact, and a limiting column 504 is also fixedly connected to the side of the slider 400 close to the ratchet wheel 501. Through the rotation of the roller head 300, the ratchet wheel 501 is driven to rotate, and then the pawl 503 is driven to rotate. Subsequently, the pawl teeth on the ratchet wheel 501 gradually move away from the pawl 503, and the pawl 503 will rotate through the rotating column 502, and then reach the limiting column 504, so as to mutually contact the pawl teeth on the ratchet wheel 501 to prevent it from rotating back.
[0029] In one embodiment, as Figure 1 and Figure 4 shown, a limiting component for limiting the roller head 300 is arranged on the side of the support frame 100 away from the roller head 300. The limiting component includes a threaded hole 601, the threaded hole 601 is opened on the side of the roller head 300 close to the mounting hole 200, and a bolt 602 is threadedly connected in the threaded hole 601. By rotating the bolt 602, it reaches the inside of the threaded hole 601.
[0030] In one embodiment, as Figure 1 and Figure 2As shown in the figure, a lifting component for lifting the slider 400 is provided at the top of the support frame 100. The lifting component includes a first limiting groove 701 opened at the top of the support frame 100. A first limiting block 702 is slidably connected in the first limiting groove 701. A second limiting groove is opened at the inner bottom of the support frame 100. A second limiting block 703 is slidably connected in the second limiting groove. A threaded rod 704 is rotatably connected between the first limiting block 702 and the second limiting block 703, and the threaded rod 704 is threadedly connected to the inside of the slider 400. A limiting rod 705 is also fixedly connected between the first limiting block 702 and the second limiting block 703, and the limiting rod 705 is slidably connected to the inside of the slider 400. By rotating the threaded rod 704, the slider 400 is driven. Since the limiting rod 705 is also provided inside the slider 400, the rotation of the threaded rod 704 only drives the slider 400 to perform horizontal lifting and lowering.
[0031] In one embodiment, as Figure 1 and Figure 2 shown, an adjusting component for adjusting the first limiting block 702 is provided on one side of the support frame 100 away from the roller head 300. The adjusting component includes a chute 801 opened in the upper middle part of the side of the support frame 100 away from the roller head 300. A locking nut 802 is rotatably connected in the chute 801, and the locking nut 802 is threadedly connected to the inside of the first limiting block 702. By rotating the locking nut 802, it approaches or moves away from the first limiting block 702.
[0032] In one embodiment, as Figure 1 and Figure 2 shown, protective pads are provided inside several of the mounting holes 200 to prevent the roller head 300 from being worn.
[0033] In one embodiment, as Figure 1 shown, one end of both the locking nut 802 and the bolt 602 is hexagonal, which is convenient for rotating the locking nut 802 and the bolt 602.
[0034] In one embodiment, as Figure 1 and Figure 2 shown, a turntable is provided on one side of the threaded rod 704 close to the first limiting block 702, which is convenient for rotating the threaded rod 704.
[0035] In one embodiment, as Figure 1 shown, the diameter of one end of the locking nut 802 away from the roller head 300 is larger than that of the mounting hole 200, preventing the locking nut 802 from passing through the mounting hole 200 and thus failing to achieve the limiting effect.
[0036] The above embodiments disclose a self-locking gear structure for the three-roller head of a roving frame. Among them, first, a ratchet wheel 501 is installed on the roller head 300. Subsequently, the roller head 300 is installed according to different requirements. After finding a suitable position, one end of the roller head 300 is installed in the mounting hole 200. Subsequently, by rotating the bolt 602, it reaches inside the threaded hole 601, thereby limiting the roller head 300 to prevent it from falling. Subsequently, according to the position of different roller heads 300, adjustment is carried out. By rotating the turntable, the threaded rod 704 is driven, and then the slider 400 is driven. Since a limiting rod 705 is also provided inside the slider 400, the rotation of the threaded rod 704 only drives the slider 400 to move horizontally up and down. Subsequently, the locking nut 802 is rotated to move it away from the first limiting block 702. Then, the first limiting block 702 is pushed to move it in the first limiting groove 701. Subsequently, the second limiting block 703 is driven by the limiting rod 705 to move in the second limiting groove at the same time, thereby driving the slider 400. After moving to a suitable position, the locking nut 802 is rotated again to reach inside the first limiting block 702 to limit and fix it. After the adjustment is completed, the pawl 503 abuts against the ratchet wheel 501. Subsequently, the rotation of the roller head 300 drives the ratchet wheel 501 to rotate, and then drives the pawl 503 to rotate. Subsequently, the pawl teeth on the ratchet wheel 501 gradually move away from the pawl 503, and the pawl 503 rotates through the rotating column 502. Subsequently, at the limiting column 504, the pawl teeth on the ratchet wheel 501 are abutted against each other to prevent it from rotating back, and it does not interfere with the normal rotation of the ratchet wheel 501.
[0037] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
