The O-frame has the disadvantage that the heald clamp is not suitable for high speeds because of its weak connection strength.
If J type and C type heald frame are used in crank shedding loom, according to general connected mode, the ring lock joint that heald frame connecting rod upper portion has the bush is on the heald frame lug, and connecting rod lower part adopts fore-and-aft swing's round pin axle to be connected with the lifting arm, and connecting rod upper and lower part passes through the lead screw and connects, conveniently adjusts the heald frame height. According to the connection mode, the heald lifting feet vertically swing up and down, the heald frame connecting rod is driven to move up and down and simultaneously generate micro back and forth swing, the back and forth swing can cause the abrasion of the lifting lugs, and the service life is shortened. When the height is adjusted through the screw rod, the deflection of the connection of the upper part of the heald frame connecting rod can be caused, and the connection contact of the lifting lugs is poor.
Therefore, a new crank shedding heald frame connecting rod is needed to be designed to be adaptive to J-shaped and C-shaped heald frame structures, and the problems of heald frame disassembly, running abrasion, inconvenient adjustment and the like are solved.
