The power source can only come from the spindle opening mechanism, which has many defects: (1) low structural integration, large space occupation, and high cost; (2) high requirements for structural integration reliability, which is not conducive to high-speed looms ; (3) In terms of vibration and noise, multiple mechanism transmissions convert periodic reciprocating motion, and the spindle load fluctuates greatly periodically, causing serious vibration and noise problems of the whole machine; (4) The process adjustment is cumbersome and complicated, which is not conducive to operation; for example , when adjusting the fabric pattern, it is often necessary for a professional mechanic to replace a certain combination of cam groups or adjust the opening angle of the opening mechanism, which is very cumbersome operation.

Based on this, with reference to FIGS. 1 to 3 , an embodiment of the present application provides a shedding mechanism, which is applied to a loom and can realize the decoupling of the movement of the shedding mechanism and the movement of the main shaft. The above-mentioned opening mechanism may include multiple heald frames 1 and at least one stator module 2; wherein:

The stator module 2 is connected to the loom stand 5, and each stator module 2 has at least one stator unit 21;

Each heald frame 1 can be integrated with at least one mover unit, and the mover unit is slidably matched in the stator unit 21; each heald frame 1 is used to move relative to the stator unit 21 under the electromagnetic action of the mover unit and the stator unit 21. Move back and forth in a straight line in the vertical direction.

In this embodiment, the heald frame 1 can have a frame-like structure, and the brown frame 1 can include a frame. A plurality of healds 17 can be arranged at intervals in the heald frame 1 , and the healds 17 are provided with healds for warp yarns to pass through. Eye, after the warp yarn passes through the heddle eyelet, it can be driven by the heald frame 1 to move up and down in the vertical direction. A shed for the weft yarn to pass through will be formed between the warp yarns of each heald frame 1.

In this embodiment, the mover unit can be directly integrated in the heald frame 1, and each brown frame can have one or more mover units. There is no need to connect the brown frame and the mover unit through a connecting mechanism, which effectively improves the integration level. In some embodiments, the above-mentioned mover unit can be integrated on the outer edges of any one side or multiple sides of the heald frame 1 frame. Of course, it can be understood that the way in which the above-mentioned mover unit is integrated into the heald frame 1 is not limited to the above examples. Those skilled in the art may also make other changes under the inspiration of the technical essence of the embodiments of this specification, but as long as they are implemented The functions and effects are the same or similar as those of the embodiments of this specification, and should be covered by the protection scope of the embodiments of this specification.

In this embodiment, the above-mentioned mover unit can be a wound coil winding or a magnetic component. The specific details can be determined according to the actual situation, which is not limited in the embodiment of this specification.

The number of stator units 21 in the stator module 2 can be set corresponding to the position and number of the mover units, or only one stator unit 21 can be provided. The details can be determined according to the actual situation, and the embodiments of this specification are not limited to this.

In one embodiment, the stator module 2 can be fixed on the loom frame 5 through threaded connection or other means. The stator unit 21 is a part of the stator module 2 that is used to slidely cooperate with the mover unit to achieve electromagnetic effect. The stator unit 21 may specifically include a slot, a through hole, or a slot provided on the stator module 2 . The boss on the group 2 has a coil winding wound around it or a magnetic component 3 attached to the tank, through hole or boss.

In this embodiment, when the stator unit 21 is a trough, a through hole and a boss respectively, the mover unit can be configured to include a slider part, a core integrated on the heald frame 1 and slidably matched with the stator unit 21 . part and tank part. When coil windings are provided in the stator unit 21, magnetic components 3 should be provided in the mover unit; conversely, when magnetic components 3 are provided in the stator unit 21, coil windings should be provided in the mover unit.

Taking the coil windings in the stator unit 21 and the magnetic component 3 in the mover unit as an example, when the coil windings are supplied with alternating current, a traveling wave magnetic field can be generated in the air gap, and the mover unit will be cut by the traveling wave magnetic field. An electromotive force is induced and a current is generated, which interacts with the magnetic field in the air gap to generate electromagnetic thrust. Since the stator unit 21 is in a fixed state, the heald frame 1 will follow the moving sub-unit in linear motion under the electromagnetic thrust.

In the same way, when the magnetic component 3 is installed in the stator unit 21 and the coil winding is installed in the mover unit, when the coil winding is supplied with alternating current, the stator unit 21 will induce an electromotive force and generate a current under the cutting action of the traveling magnetic field generated. This current interacts with the magnetic field in the air gap to generate electromagnetic thrust. Since the stator unit 21 is in a fixed state, the heald frame 1 will follow the moving sub-unit in linear motion under the electromagnetic thrust. By adjusting the phase of the external power supply of the coil winding, the movement direction of the heald frame 1 can be switched, so that the up and down reciprocating motion of the heald frame 1 can be realized.

The module 2 has at least one stator unit 21; by integrating at least one mover unit on each heald frame 1, a complex transmission mechanism can be omitted, the structure is simplified, and the cost is reduced; wherein, the mover unit and the stator module The stator unit 21 of 2 is slidingly matched. Using the linear motor principle, the electromagnetic effect generated between the mover unit and the stator unit 21 can drive the mover unit to move relative to the stator unit 21, thereby directly driving the heald frame 1 relative to the loom table. The frame 5 reciprocates up and down in the vertical direction, which realizes the decoupling of the movement of the opening mechanism and the movement of the main shaft. It does not rely on the complex transmission mechanism in the middle, which can effectively reduce the load of the main shaft and is conducive to the high speed of the loom. And because the shedding mechanism only has up and down reciprocating motion in the vertical direction, it avoids the horizontal vibration introduced by the complex transmission mechanism, thereby reducing the vibration and noise during the operation of the loom.

In one embodiment, referring to FIG. 3 , the stator module 2 may also include a connecting component 4 on which the stator unit 21 is installed. The connecting component 4 is used to connect the loom frame 5 .

In some embodiments, the magnetic component 3 can be integrated on the first side frame 11 by attachment as shown in FIG. 2 , or the magnetic component 3 can be integrated on the second side frame by attachment as shown in FIG. 3 on border 12. The manner in which the above-mentioned mover unit is integrated into the heald frame 1 is not limited to the above examples. Those skilled in the art may also make other changes under the inspiration of the technical essence of the embodiments of this specification, but as long as the functions and effects achieved are consistent with this specification. The same or similar embodiments shall be included in the protection scope of the embodiments of this specification.

As shown in Figure 2, the positioning slots 18 can be opened inside the first side frame 11 and the second side frame 12 and distributed at vertical intervals.
