DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 4 In order to solve the problem that when the needle feeding structure assembly needs to be maintained, the outer assembly shell fixed by multiple sets of bolts needs to be disassembled, which consumes too much time and effort, the following preferred technical solutions are provided:

[0021] A fully automatic roller loom single needle feeding structure assembly, including a mounting frame 1 and an outer assembly shell 2 that are docked and installed with each other, a needle feeding structure body 3 is installed in the cavity of the mounting frame 1, and a connecting block 4 is installed at the top and bottom of the cavity of the mounting frame 1. The inner wall of the connecting block 4 is threadedly connected to a fixing mechanism 5, and one end of the fixing mechanism 5 passes through the outer assembly shell 2. The fixing mechanism 5 includes a fixing block 51 that is rotatably connected to the outer wall of the outer assembly shell 2, and a bolt body 52 that is threadedly connected to the connecting block 4. The inner wall of the fixing block 51 is rotatably connected to a control block 53. The control block 53 One end of the bolt body 52 is fixedly connected to a threaded rod 54, and the outer wall of the threaded rod 54 is threadedly connected to a movable top block 55. Movable grooves 56 are provided on both sides of the bolt body 52, and the inner wall of the movable groove 56 is slidably connected to a reinforcing top block 57. The end of the threaded rod 54 away from the control block 53 passes through the fixed block 51, and the threaded rod 54 is rotatably connected to the inner wall of the bolt body 52, and the movable top block 55 is slidably connected to the inner wall of the bolt body 52. The outer walls of both sides of the movable top block 55 are arc-shaped structures, and the end of the reinforcing top block 57 close to the arc surface of the movable top block 55 is also an arc-shaped structure.

[0022] One side of the movable top block 55 is fixedly connected to the middle connecting block 58, the inner wall of the bolt body 52 is provided with a mounting groove 59, the inner wall of the mounting groove 59 is slidably connected to the slider body 510, one end of the slider body 510 is fixedly connected to the middle connecting block 58, and the end of the slider body 510 away from the middle connecting block 58 is fixedly connected to the elastic element 511, the elastic element 511 is fixedly connected to the bottom of the cavity of the mounting groove 59, and the middle connecting block 58 is an L-shaped structure.

[0023] Specifically, when assembling the mounting frame 1 and the outer mounting shell 2, after the outer mounting shell 2 is aligned and fits against the mounting frame 1, the bolt body 52 is threadedly connected to the connecting block 4. After the connection, the control block 53 is rotated, and the control block 53 is used to drive the threaded rod 54 to rotate, driving the movable top block 55 to translate on the inner wall of the bolt body 52. Since the outer walls of the movable top block 55 on both sides are in an arc structure, the reinforcing top block 57 is close to the end of the arc surface of the movable top block 55. Therefore, when the movable top block 55 moves to one end of the reinforcing top block 57, the reinforcing top block 57 will be pushed out of the movable groove 56, so that the reinforcing top block 57 abuts against the inner wall of the connecting block 4, thereby strengthening the connection. Only a small number of bolts are needed for stable installation. The installation and disassembly are extremely convenient, saving time and effort, and solving the problem that when the needle feeding structure assembly needs to be maintained, the outer mounting shell fixed by multiple sets of bolts needs to be disassembled, which consumes too much time and effort.

[0024] When the reinforcing top block 57 is pushed out of the movable groove 56, the slider body 510 will be driven to squeeze the elastic element 511 through the middle block 58. Therefore, when disassembling, it is only necessary to rotate the control block 53 and drive the movable top block 55 back to its original position through the threaded rod 54. The reaction force of the elastic element 511 can drive the reinforcing top block 57 back into the cavity of the movable groove 56.
