Description
Technical Field
The utility model relates to the technical field of rapier machines, in particular to a heald frame for a rapier machine, which is convenient for threading.
Background
The heald frame is an important part in a loom and is a frame with a drafting rod and a driving part connected by an upper cross beam, a lower cross beam and left and right side rails. The heald frame is provided with heald wires, warp yarns penetrating the heald wires are integrated, and the heald frame moves up and down along with the motion of the heald lifting mechanism of the loom, so that the heald frame opens the warp yarns in layers according to the program of the opening device, and weft yarns are shuttled in the warp yarns to interweave into fabrics with different patterns.
The heald eye on the existing heald wire has smaller diameter, larger difficulty when a worker threads, and low threading efficiency.
Disclosure of Invention
The utility model aims to solve the technical defects and provides the heald frame for the rapier machine, which is convenient for threading and can realize quick threading.
The utility model discloses a heald frame for a rapier loom, which comprises a frame, two groups of heald rods which are vertically symmetrically arranged in the frame, and healds which are arranged on the heald rods in a penetrating way, wherein each heald wire comprises a connecting sleeve, a steel sheet, steel wires and a buckle, the connecting sleeves are respectively sleeved on the upper and lower groups of heald rods, the steel sheets are vertically upwards arranged on the connecting sleeves at the lower side, the upper ends of the steel sheets are positioned at the middle positions of the upper and lower groups of heald rods in the vertical direction, the upper ends of the steel sheets are provided with U-shaped grooves with upwards openings, the two sides of each U-shaped groove are vertically upwards provided with steel wires, the upper ends of the steel wires are fixed with the connecting sleeves at the upper side, each buckle comprises a clamping part and an elastic part, the clamping part is clamped on the steel sheet at one side of each U-shaped groove, one end of each elastic part, which is far away from the clamping part, is propped against the steel sheet at the other side of the U-shaped groove, the lower side of each elastic part is upwards arranged into an arc-shaped indent, and the upper side of each elastic part is provided with an inclined sliding surface.
When the scheme is used for threading, the yarn passes through the two steel wires at the upper side, the steel wires can generate certain deformation, the length of the steel wires is long, the yarn can easily pass through the two steel wires at the upper side, then the yarn downwards slides into the U-shaped groove through the upper side of the elastic part, the upper side of the elastic part is set to be an inclined sliding surface, the yarn can slide into the U-shaped groove more easily through the inclined sliding surface, and the lower side of the elastic part is set to be an arc-shaped indent upwards, and the elastic part is propped against the steel sheet away from one end of the clamping part, so that the yarn is difficult to separate from the U-shaped groove, thereby realizing quick threading.
Further, the elastic metal sheet is arranged on the arc-shaped concave arranged on the lower side of the elastic part in a fitting mode, and the yarns can contact the elastic metal sheet but not directly contact the lower side of the elastic part, so that the wear resistance of the yarn is improved.
The beneficial effects of the utility model are as follows: through the vertical steel wire and the buckle that upwards set up in U-shaped groove both sides, because the steel wire can produce certain deformation and steel wire length is longer, consequently can pass the yarn fast from between two steel wires of upside, then slide into the U-shaped inslot with the slope sliding surface of yarn downward through elastic component upside, realize quick threading, the threading degree of difficulty greatly reduced, threading efficiency promotes greatly.
