Description

Circular loom Technical Field The utility model belongs to the field of weaving equipment, and particularly relates to a circular loom. Background The circular loom is industrial equipment for weaving cylindrical cloth, the cylindrical cloth is formed by interweaving warp and weft, the warp is arranged in a wire passing hole of a heald wire in a penetrating way, the heald wire and the warp arranged in the heald wire are driven to reciprocate up and down through the up-and-down reciprocating motion of a heald belt, and the weft passes through the warp which reciprocates up and down to weave the cylindrical cloth. At present, a circular loom generally adopts a plane cam to drive the end part of a swinging rod to swing up and down so as to drive a heald belt to move up and down, and in order to connect the swinging rod, a heald belt assembly comprises three heald belts, a connecting piece is connected between two heald belts, and the end part of the swinging rod is rotationally connected on the connecting piece. When the swinging rod swings, the swinging rod rotates relative to the connecting piece and drives the connecting piece to move, and then the heald belt moves up and down, so that the structure is complex, meanwhile, because the swinging rod swings up and down, the moving track of the swinging rod is arc, in the swinging process of the swinging rod, the connecting piece is driven by the swinging rod to displace in the vertical direction, displace in the horizontal direction also occurs, and then the heald belt and the heald wire are driven to change positions in the horizontal and vertical directions simultaneously, the heald wire displaces repeatedly in the horizontal direction, so that the heald wire can repeatedly wear warps penetrating the heald wire through holes, the warps are extremely damaged, and meanwhile, a great amount of wear is caused on the heald wire, and the service life of the heald wire is shortened. Disclosure of utility model The utility model aims to solve the technical problem of providing a circular loom so as to solve the problem that heald wires are worn out by repeatedly moving in the horizontal direction when driving the warp wires to move up and down. The circular loom comprises a heald belt assembly, an upper roller and a lower roller for tensioning the heald belt assembly, and a linear driving mechanism provided with an output rod, wherein the heald belt assembly comprises two heald belts and two rows of heald wires which are arranged in parallel, the two heald belts are respectively coated on the upper roller and the lower roller, the upper end and the lower end of the two rows of heald wires are respectively connected with the end parts of the two heald belts so as to form an annular heald belt assembly, through holes are formed in the heald belts, and the output rod is arranged in the through holes in a penetrating way, and drives the heald wires to reciprocate up and down by pulling the heald belts up and down. The technical scheme has the following technical effects: According to the utility model, the circular loom is provided with the structure that the output rod of the linear driving mechanism is directly connected with the heald belt of the heald belt assembly, the linear driving mechanism converts the rotary motion into the linear motion in the vertical direction of the heald belt, so that the heald wires connected to the heald belt are driven to pull the warp wires penetrating through the heald wires to reciprocate in the vertical direction, the heald wires are only displaced in the vertical direction in the whole motion process, the warp wires are pulled or pressed down, excessive abrasion to the warp wires caused by the displacement of the heald wires in the opposite water direction is avoided, and a large amount of dust is avoided due to excessive abrasion of the warp wires while the warp wires are effectively protected. And because the driving structure for driving the heald belt component is a linear driving mechanism, the output rod is directly worn in the heald belt to drive, and each heald belt component only needs to be provided with two heald belts to realize the up-and-down movement of two rows of healds, so that the structure of the heald belt component is simplified, and the production and processing difficulty of the heald belt component is reduced. In the circular loom, one side of the heald belt facing the linear driving mechanism is provided with the mounting block, the mounting block is provided with the mounting hole aligned with the through hole, and the output rod penetrates through the mounting hole and stretches into the through hole to be linked with the heald belt. The mounting holes on the mounting blocks can increase the contact area between the output rod and the heald belt component, so that the heald belt is not easy to damage when the output rod moves up and down along the radial direction to drive the heald belt to move up and d
