In order to realize that the vertical shaft drives the needle bar to rotate, the side wall of the vertical shaft is provided with a vertical groove 2301 which runs through the hollow inner cavity and extends vertically, and the upper part of the needle bar is detachably connected with a key 221, the key 221 is matched with the vertical groove 2301, on one hand, the needle bar is guided to move up and down relative to the vertical shaft, and on the other hand, the vertical shaft can drive the needle bar to rotate together when rotating. The lower part of the needle bar is connected with a needle bar driving block 222, and the needle bar driving block is hinged with a driving connecting rod, so when the needle bar driving block rotates along with the needle bar, the driving connecting rod is kept still, and when the driving connecting rod moves up and down, the needle bar driving block and the needle bar can be driven to move together.
In order to avoid the space above the vertical shaft, the needle rod is convenient to maintain and replace. The cross shaft 24 is rotatably supported on the left side wall or the right side wall of the machine head shell, one end of the cross shaft outwards penetrates through the side wall and is connected with a transmission assembly, the other end of the cross shaft extends towards the upper part of the vertical shaft but does not extend above the vertical shaft, and the vertical shaft is driven by the turning transmission mechanism. Therefore, the maintenance and the replacement of the needle bar cannot be influenced, but the transmission is not stable enough because the other end of the transverse shaft is suspended.
Therefore, in order to ensure stable transmission, the maintenance and replacement of the needle bar are not influenced. The transverse shaft is rotatably supported on the left side wall and the right side wall of the machine head shell, a driving shaft 26 parallel to the transverse shaft is further arranged, an intermediate transmission assembly is arranged between the driving shaft 26 and the transverse shaft, and a maintenance hole 243 which can enable the needle rod to penetrate upwards is arranged on the transverse shaft 24 corresponding to the vertical shaft.
Because the cross shaft is rotatably supported on the left side wall and the right side wall of the machine head shell, and the connecting parts of the middle transmission assembly, the direction-changing transmission mechanism and the cross shaft are positioned between the left side wall and the right side wall of the machine head shell, the transmission is more stable relative to a mode that the cross shaft is suspended in the air; meanwhile, the transverse shaft is provided with a maintenance hole corresponding to the vertical shaft, which can lead the needle bar to penetrate upwards, thereby also considering the maintenance and replacement of the needle bar.
In one embodiment, the intermediate transmission assembly includes a transmission belt 25, a transmission pulley correspondingly mounted on the horizontal shaft and the driving shaft and in transmission connection with the transmission belt, specifically, a driving pulley 261 mounted on the driving shaft, and a synchronous pulley 242 mounted on the horizontal shaft.
