Definitions

  • the present invention belongs to the technical field of knitting machinery, in particular to a compound needle in a flat knitting machine.
  • a latch needle in the prior art has a needle latch that is rotatable on a needle bar. Actions of looping, knocking-over, tucking, clearing, needle turning, needle connecting and the like of a loop by the needle latch are completed by opening and closing of the needle latch in combination with a main needle and yarns. Since the rotation of the needle latch requires space, a reed is disposed at a needle turning position of the main needle, such that this latch needle requires a larger vertical stroke to complete these knitting functions.
  • the opening action of the needle latch also needs to be completed by means of a hairbrush or yarns. If the hairbrush is not appropriate or the installation position is not in place, defects such as missing needles are likely to occur, and the life and installation accuracy requirements on the hairbrush are relatively high.
  • the compound needle comprises a main needle and a needle sleeve sleeving the main needle.
  • the main needle is divided into three parts: a head portion, a middle portion and a tail portion, wherein the head portion has a needle hook, a stop end is disposed at a junction between the middle portion and the tail portion, an elongated limiting bar is disposed on the right side of the middle portion of the main needle, and the limiting bar and the front end of the middle portion form a U-shaped structure; the right side of the junction between the head portion and the middle portion of the main needle protrudes outwards to form a bump, and the left side thereof relative to the right side is bent inwards to form an inwards-recessed make-way groove; an inwards-recessed needle groove is formed in the front side and the rear side of the bump; the needle sleeve is divided into a front section, a main section and
  • US2002112509 discloses a similar structure of a compound needle as in CN201810043037 .
  • the compound needle having such a structure can complete the actions of clearing, looping, needle turning, needle connecting and the like of the loop by virtue of the cooperation of the main needle and the needle sleeve, thereby being capable of substituting for the needle latch.
  • the structure of the main needle is too complicated, and the requirement on the processing precision of the main needle and the needle sleeve is high.
  • the apex angle of the needle sleeve is inclined towards the main needle, so that when the apex angle closes the hook, the width of the closed position is increased, and therefore, the passing loop becomes large, which affects the knitting effect.
  • An objective of the present invention is to provide a compound needle in a flat knitting machine, which has a simple structure and completes clearing, looping, needle turning, needle connecting and other actions of a loop, instead of a latch needle and a main needle.

  • a trajectory surface is formed on one side, facing the needle sleeve, of the main needle; a salient point is formed on one side, facing the main needle, of the needle sleeve; the salient point cooperates with the trajectory surface of the main needle, such that when the needle sleeves moves along the main needle, the apex angle moves from the accommodating grooves of the main needle to close the needle hook of the main needle.
  • the trajectory surface of the main needle is positioned below the lug boss and consists of a plurality of smooth concave surfaces and convex surfaces; the trajectory surface is provided with a first notch and a second notch; the salient point on the needle sleeve moves along the trajectory surface; when the apex angle of the needle sleeve is located in the accommodating groove of the main needle, the salient point is positioned at the second notch; when the apex angle of the needle sleeve moves upwards to close the needle hook of the main needle, the salient point is positioned at the first recess.
  • a second salient point is formed on one side, facing the main needle, of the tail end of the needle sleeve; the second salient point props against and moves vertically along the right side of the bottom of the main needle.
  • a salient point is formed on one side, facing the needle sleeve, of the main needle; a trajectory surface is formed on one side, facing the main needle, of the needle sleeve; the salient point cooperates with the trajectory surface, such that when the needle sleeve moves along the main needle, the apex angle moves from the accommodating grooves of the main needle to close the needle hook of the main needle.

  • an elastic sheet capable to be pressed by the needle groove is disposed on one side, facing away from the main needle, of the needle sleeve and is of an elongated broken line shape.
  • the needle sleeve is composed of an intermediate sheet and two side sheets; the apex angle at the top end of the needle sleeve consists of two side sheets; one side, facing the main needle, of each of two side sheets extends outwards to form two clamping strips; the corresponding clamping strips on the two side sheets form the first fastener and the second fastener.
  • the intermediate sheet and the two side sheets of the needle sleeve are assembled and molded after being machined separately, or the intermediate sheet and the two side sheets are integrally machined and molded directly.
  • the first fastener and the second fastener on the needle sleeve are positioned at the middle portion and the tail end of the needle sleeve respectively; the front side and the rear side of a position where the trajectory surface of the main needle is located are recessed inwards to form a first concave surface; the first fastener is in tight contact with the first concave surface on the front side and the rear side of the main needle; the tail end of the main needle is provided with a stop end; the front side and the rear side above the stop end are recessed inwards to form a second concave surface; the second fastener is in tight contact with the second concave surface on the front side and the rear side of the main needle.

  • the compound needle has the characteristics that a bending direction of the apex angle of the needle sleeve is consistent with a tilting direction of the tip of the needle hook, and the width of the closed position of the needle sleeve and the needle hook is reduced, thereby reducing the knocking-over resistance of the loop, and reducing the size of the knocked-over loop.
  • the design in which the needle hook is opened or closed by sliding the needle sleeve also reduces the clearing stroke of the loop, thereby improving the knitting speed of a fabric and improving the production efficiency.
  • An elastic sheet is disposed above the needle sleeve and is integrally molded with the intermediate sheet of the needle sleeve.
  • This elastic sheet is flexible rather than rigid, and is thus not prone to brakeage.

  • the clamping strips and the two side sheets of the needle sleeve are molded integrally.
  • the fastener is part of the needle sleeve.
  • the needle sleeve sleeves the main needle by the cooperation of the fastener and the concave surface.

  • the tail of the needle sleeve comes into contact with the stop end of the main needle.
  • the two side sheets of the needle sleeve are embedded in the accommodating grooves of the main needle, which is beneficial to stabilize the size of the loop.
  • the needle sleeve has the same width as the main needle, which not only ensures the strength, but also ensures stable sliding in the needle groove, and is beneficial to stable knitting of a fabric and flatting of the fabric surface.
  • the needle hook is opened or closed by sliding of the needle sleeve on the main needle, such that the interaction between the needle sleeve and the main needle completes the traditional actions of looping, knocking-over, tucking and clearing instead of the traditional latch needle, thereby realizing capturing and discharge of the looped yarn.
  • the apex angle at the head of the needle sleeve first passes over the needle hook for a certain distance, ensuring that the head of the needle sleeve does not collide with the tip of the needle hook, and then runs downward to prevent the tip of the needle hook from being deformed.
