The sword transmission wheel 10 is rotatably connected to the seat body 8, and the supporting component is used to make the first surface of the sword belt 13 abut against the outer peripheral wall of the sword transmission wheel 10. Around the circumference of the sword transmission wheel 10, the peripheral wall of the sword transmission wheel 10 is provided with a plurality of convex teeth 11 for cooperating with the first through hole 7.

[0041] The rapier belt device according to the embodiment of the present application can be used in a rapier loom.

[0042] The guide rail 9 is used to enable the sword belt 13 to move along a specified trajectory.

[0043] When the first surface of the rapier belt 13 abuts against the outer peripheral wall of the rapier wheel 10 , the protruding teeth 11 of the rapier wheel 10 can be inserted into the first through hole 7 , so that when the rapier wheel 10 rotates, the rapier belt 13 can be driven to move.

[0044] The abutting component enables the sword belt 13 to abut tightly against the sword transmission wheel 10 , thereby reducing the risk of the sword belt 13 being separated from the sword transmission wheel 10 and improving the transmission efficiency of the sword transmission wheel 10 .

[0045] In the embodiment of the present application, along the axial direction of the sword transmission wheel 10, two limiting portions 12 can be arranged at intervals on the peripheral wall of the sword transmission wheel 10. The limiting portions 12 are arranged around the circumference of the sword transmission wheel 10, and the opposite sides of the two limiting portions 12 are arranged at an angle to form a V-shaped structure, so that when the sword belt 13 and the sword transmission wheel 10 are matched, the limiting portions 12 can play a guiding role.

[0063] The two abutting wheels 16 increase the force applied to the sword belt 13 , so that the sword belt 13 and the sword transmission wheel 10 can be closely abutted.

[0064] The two abutting wheels 16 abut against the two sides of the contact point between the sword belt 13 and the sword transmission wheel 10 respectively. Under the action of the abutting wheels 16, the sword belt 13 can be slightly bent toward the sword transmission wheel 10, so that the sword belt 13 can fit closely with the sword transmission wheel 10.

[0065] In some embodiments, the sword wheel 10 is provided with a plurality of weight-reducing holes 14 .

[0066] The plurality of weight-reducing holes 14 can save the materials required for manufacturing the sword transmission wheel 10 and save the cost. On the other hand, they can reduce the weight of the sword transmission wheel 10 .

[0067] The above embodiments are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made by ordinary technicians in this field to the technical solutions of the present invention should all fall within the protection scope determined by the claims of the present invention.
