attached figure 1 To attach image 3 Respectively represent the driving parts of several common heald frames in the prior art. The heald frames are respectively pulled and driven by the hanging heald ropes from both sides of the heald frames. The low-speed opening mechanism only realizes reciprocating motion, but when it moves at high speed, it will cause Inconsistent motion at both ends, unsynchronized motion creates additional or redundant force while achieving reciprocating motion

Embodiment Construction
[0018] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0019] attached Figure 4 It is a perspective view of the shedding mechanism of the heald frame which adopts the present invention and is hinged with the slider in the middle of the beam. The heald frame 5 in this embodiment is jointly driven by two sets of driving sub-mechanisms. The driving sub-mechanism on the left side of the figure is mainly composed of a rotating shaft 11, a crank 12 and a connecting rod 13. The crank 12 rotates with the rotating shaft 11, and the crank 12 Hinged with the connecting rod 13; similarly, the driving sub-mechanism located on the right side of the figure is mainly composed of a rotating shaft 21, a crank 22 and ...

The invention discloses a heald frame hinged with sliding block in middle of crossbeam which includes a sliding block; the sliding block is hinged with the heald frame and can slide along the guide frame of the sliding block; the sliding block is provided with an oblate connector; the oblate connector is provided with an oblate top part and a neck part supporting the top part on the surface of the sliding block; the middle of the crossbeam of the heald frame is provided with an elastic oblate groove; the top part of the oblate connector can be arranged in the elastic oblate groove in the way of being capable of rotating in each direction; during the moving process of the heald frame, the sliding block slides along the guide frame of the sliding block and the heald frame is allowed generating deflection and additional force of each direction relatively to the sliding block. The invention solves the problems of the prior art, and provides a heald frame capable of eliminating the vibration force and vibration moment generated during the moving process of the heald frame.
Description
technical field [0001] The invention relates to a heald frame of an air-jet loom. Background technique [0002] The opening mechanism of the air-jet loom is used to complete the alternate lifting of the upper and lower warp yarns. In the past, the speed of the loom was only 100-200 rpm, but now the speed of the air-jet loom can reach 900-1000 rpm. The heald frame is a flat and elongated part. The drive of the heald frame often drives the same heald frame from the left and right sides, so the movement of the two sides of the heald frame cannot be completely synchronized. The design of the mechanism should start from the high speed of the loom and maximize the There is no unnecessary twist and torsional vibration on the heald frame. attached figure 1 to attach image 3 Respectively represent the driving parts of several common heald frames in the prior art. The heald frames are respectively pulled and driven by the hanging heald ropes from both sides of the heald frames. Th...
