[0020] 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.
[0021] See also Figure 1-4 As shown, a needle bar frame for an embroidery machine head includes a mounting frame 1, a needle bar mechanism 2 is installed inside the mounting frame 1, a threading frame 3 is fixedly connected to one side of the mounting frame 1, and the threading frame 3 is used in conjunction with the needle bar mechanism 2 to guide the thread, thereby facilitating sewing and preventing the thread from being entangled. An oil storage box 4 is fixedly connected to one side of the mounting frame 1, and the interior of the oil storage box 4 is used to store oil needed for maintaining the needle bar mechanism 2. A servo motor 5 is bolted to one side of the oil storage box 4, and the output shaft of the servo motor 5 is fixedly connected to a threaded rod 6, and the surface of the threaded rod 6 is screwed The threaded rod 6 is connected with a sleeve 7, and the top of the threaded rod 6 is fixedly rotatably connected with a support plate 14. One side of the support plate 14 is fixedly connected to the surface of the mounting bracket 1. Under this function, one end of the threaded rod 6 can be supported, so that the threaded rod 6 will not easily vibrate significantly when it is rotated under the action of the servo motor 5, effectively improving the stability of the threaded rod 6 during rotation, and avoiding the threaded rod 6 being unstable during rotation and affecting the threaded connection with the sleeve 7. One side of the sleeve 7 is rotatably connected to a connecting rod 8, and the bottom of the connecting rod 8 is fixedly connected to an oil brush 9. The oil brush 9 is designed with a flexible material. The surface of the oil brush 9 is movably connected to the surface of the needle bar mechanism 2. The surface of the mounting frame 1 is installed with a tilting mechanism 10. The tilting mechanism 10 is used in conjunction with the connecting rod 8. Under this action, when the sleeve 7 drives the connecting rod 8 to move, the connecting rod 8 can be rotated under the action of the tilting mechanism 10, so that the oil brush 9 can be rotated to one side of the needle bar mechanism 2. Under this action, the surface of the needle bar mechanism 2 is oiled. An auxiliary mechanism 13 is installed on one side of the mounting frame 1. The auxiliary mechanism 13 can guide the connecting rod 8 when it moves. Thereby, the connecting rod 8 will not be easily displaced during movement, and the stability of the connecting rod 8 during use is effectively improved. Both sides of the connecting rod 8 are fixedly connected with a torsion spring 12, and the other end of the torsion spring 12 is fixedly connected to one side of the sleeve 7. Under this action, when the connecting rod 8 drops above the oil storage box 4, the tilting mechanism 10 no longer contacts the connecting rod 8, and under the action of the torsion spring 12, the connecting rod 8 can be rotated back to its original position. Both sides of the surface of the connecting rod 8 are fixedly connected with a blocking plate 11, which can block the opening of the oil storage box 4.
[0022] The tilting mechanism 10 includes a connecting plate 101, the surface of the connecting plate 101 is fixedly connected to the inner wall of the mounting frame 1, the bottom of the connecting plate 101 is fixedly connected to an extrusion plate 102, and a locking groove 103 is provided on the top of the connecting rod 8. Under this action, when the connecting rod 8 moves upward, the extrusion plate 102 can squeeze the connecting rod 8, thereby causing it to tilt, and the locking groove 103 can limit the extrusion plate 102 under the action of the extrusion plate 102, so that the extrusion plate 102 can be more stable when squeezing the connecting rod 8. The bottom of the extrusion plate 102 is designed as an arc structure, and the bottom of the extrusion plate 102 is slidably connected to the inner wall of the locking groove 103. Under the action of the arc structure, the connecting rod 8 can be more easily rotated when the locking groove 103 contacts the extrusion plate 102.
[0023] The auxiliary mechanism 13 includes a fixed plate 131 fixed to one side of the mounting frame 1, and the surface of the fixed plate 131 is fixedly connected to a guide rod 132, and the surface of the guide rod 132 is slidably connected to a sliding block 133, one side of the sliding block 133 is rotatably connected to the surface of the connecting rod 8, and one side of the sliding block 133 is fixedly connected to one end of the torsion spring 12. Under this action, when the sleeve 7 drives the connecting rod 8 to move, the connecting rod 8 can be effectively guided by the cooperation of the sliding block 133 and the guide rod 132, so that the connecting rod 8 can be more stable when moving, avoiding the situation where the connecting rod 8 is not stable enough when driving the oil brush 9 to oil the needle bar mechanism 2, resulting in uneven oiling.
[0024] It is worth noting that the technical features such as the mounting frame 1, needle bar mechanism 2 and threading frame 3 proposed in this technical solution should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected according to conventional methods in the field, and this technical solution will not be further elaborated.
[0025] Working principle: first, add oil to the inside of the oil storage box 4. Then, when the needle bar mechanism 2 needs to be oiled, the staff turns on the servo motor 5. Under the action of the servo motor 5, the threaded rod 6 can drive the sleeve 7 to move under the action of the surface thread, and the sleeve 7 will drive the connecting rod 8 to move when it moves. When the connecting rod 8 moves, it will squeeze the blocking groove 103 through the blocking groove 103, so that the connecting rod 8 can rotate. Then the connecting rod 8 can drive the oil brush 9 to rotate so that it contacts the surface of the needle bar mechanism 2. Under the action of the oil on the surface of the oil brush 9, the needle bar mechanism 2 is oiled. After the oiling is completed, the servo motor 5 lowers the connecting rod 8. When the blocking groove 103 no longer contacts the extrusion plate 102, the connecting rod 8 can be rotated back to its original position with the cooperation of the torsion spring 12, so that the oil brush 9 can move to the inside of the oil storage box 4, and the opening of the oil storage box 4 can be blocked under the action of the blocking plate 11.
