  • a cylindrical barrel is arranged on the frame, a compression spring is arranged in the cylindrical barrel, and the lower end of the upper top column extends into the cylindrical barrel and is connected with the compression spring.
  • the two ends of the suture needle are placed on two rollers.
  • the middle of the suture needle is driven to bend downward.
  • the two ends of the suture needle are still squeezed, so under the triple action of the mold and the roller, the suture needle is bent.
  • the foot switch is released, the mold will do it.
  • the bent suture needle is bounced back to its original position, and then the next suture needle is bent.
  • the position of the limit plate can be adjusted.

  • the operation process is as follows: adjust the position of the two limit plates 9 according to the length of the suture needle, put the suture needle in the control range of the operation storage board, prepare for operation, place a straight suture needle in the rectangular 11 space, step on it With the foot switch 18, the mold 17 is pressed down, and after contacting the suture needle, it continues to press down, and the middle part of the suture needle and the upper thimble are pressed down together.
  • the mold 17 since the diameter of the mold 17 is larger than the distance between the two rollers 7, so The mold 17 also pushes the guide rod 4 through the roller 7 and the plate 7 to retract to both sides, and the two ends of the suture needle are placed on the two rollers 7 and cannot be pressed down, so the suture needle is bent and the foot switch 18 is released. , The mold 17 is retracted, the upper ejector rod and the roller 7 lose pressure, and return to the original position under the action of the longitudinal return spring 13 and the transverse return spring 5, and the bent suture needle is also ejected under the action of the upper ejector. At this time, press the next suture needle.
