Circular weaving machine jacquard mechanism comprising air cylinders for lifting heald rods

Abstract

The invention provides a circular weaving machine jacquard mechanism comprising air cylinders for lifting heald rods. The circular weaving machine jacquard mechanism comprises a circular rack, wherein the rack is internally provided with an inner-layer jacquard device and an outer-layer jacquard device; each of the inner-layer jacquard device and the outer-layer jacquard device comprises a plurality of jacquard units; the jacquard units are respectively and uniformly arrayed along a first circle and a second circle; the first circle and the second circle are both coaxial with the circular rack; any jacquard unit comprises an air cylinder, a heald rod, a guide rod, an oscillating rod, an electromagnet and an armature; the air cylinders, the guide rods and the electromagnets are respectively and fixedly arranged on the rack; the lower ends of the heald rods are placed on heald rod lifting rods which are fixedly connected with piston rods of the air cylinders; a slide pair is arranged between each guide rod and each heald rod; the oscillating rods are connected with the rack through hinge pins; the armatures are connected onto the oscillating rods; the armatures are adjacent to the electromagnets; a convex step is arranged in the outer periphery of the lower part of each heald rod; a lifting hook is convexly arranged in each oscillating rod along the direction of the corresponding heald rod. The heald rods are ejected up by the piston rods and the electromagnets and the oscillating rods are used for controlling the falling of the heald rods. The quantity of sheds can be set freely, the quantity of shuttles can be increased and the layer quantity of tubular fabrics is increased correspondingly.

Description

Technical field: [0001] The invention relates to the field of machinery, in particular to textile machinery, in particular to an opening device of a circular loom, in particular to a jacquard mechanism of a circular loom for lifting a heald rod by a cylinder. Background technique: [0002] The circular loom is provided with a shedding mechanism. The opening mechanism includes two layers of heald frames inside and outside, and any layer of heald frames includes N groups of heald frames (N is generally a multiple of 6), and the N groups of heald frames are evenly arranged on the circular frame along the circumferential direction. A plurality of heddles are respectively included in each heald frame, and a heald eye is respectively arranged in the middle of each heddle, and the warp thread passes through the heald eye. A cam is coaxially arranged in the circular frame, and the cam is provided with a curved groove or a curved flange in the circumferential direction. When the cam...
