Fig. 2 is the connection diagram of first, second heald frame and the second rotating shaft in the driving device for harness frame shown in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments the present invention is described in further detail explanation.
Fig. 1 and Fig. 2 show schematically show the driving device for harness frame according to one embodiment of the present invention.
As depicted in figs. 1 and 2, driving device for harness frame comprises: central rotating shaft 410, first heald frame 21, second heald frame 22, is sheathed on conjugate cam 420, impeller 421 and one second rotating shaft (422) of central rotating shaft 410, impeller 421 is tangent with conjugate cam 420, and be connected to the second rotating shaft 422 by one second connecting rod 423, second rotating shaft 422 is connected with the first heald frame 21, second heald frame 22, and be arranged in parallel, the second rotating shaft 422 is between the first heald frame 21 and the second heald frame 22.
As shown in the figure, conjugate cam 420 comprises the first overlapped cam 4201, second cam 4202, first cam 4201 and the second cam 4202 is connected by camshaft, and the protuberance of the first cam 4201, second cam 4202 is arranged in a crossed manner.
Impeller 421 comprises the first drive rotor 4210, second drive rotor 4211, first drive rotor 4210 and the second drive rotor 4211 is connected by rotor connecting shaft 4212, and impeller 421 is connected in the middle part of rotor connecting shaft 4212 with board holder pivots.
Conjugate cam 420 is sheathed on one end of central rotating shaft 410, first drive rotor 4210 and the second drive rotor 4211 are located at the both sides of one of them cam protrusion of conjugate cam 420 respectively, tangent with conjugate cam 420, wherein, first drive rotor 4210 and the second cam 4202 tangent, the second drive rotor 4211 and the first cam 4201 tangent.Impeller 421 is connected to the second rotating shaft 422 by one second connecting rod 423, second connecting rod 423 comprises a connection armed lever 4231 and and connects pole 4232, connect armed lever 4231 one end and be fixedly connected on the first drive rotor 4210 of impeller 421 and the junction of rotor connecting shaft 4212, the other end is rotationally connected with and connects the end, one end of pole 4232, connect pole 4232 not be connected one end that armed lever 4231 connects and be fixedly connected on the second rotating shaft 422.
Second rotating shaft 422 and the first heald frame 21 and the second heald frame 22 be arranged in parallel, first heald frame 21 and the second heald frame 22 are connected to the second rotating shaft 422 wall respectively by the 3rd connecting rod 201 and the 4th connecting rod 202, and the second rotating shaft 422 is between the 3rd connecting rod 201 and the 4th connecting rod 202.
Thus, impeller 421 be connected the first drive rotor 4210 that armed lever 4231 connects and promoted by the second cam 4202 of conjugate cam 420, impeller 421 swings around the 5th connecting rod 1101, and the first drive rotor 4210 end declines, and the second drive rotor 4211 end rises; The one end connecting pole 4232 is rotationally connected with owing to connecting armed lever 4231, and connect pole 4232 not be connected one end that armed lever 3231 connects and be fixedly connected on the second rotating shaft 422, when connecting armed lever 4231 and being subject to downward thrust, connect armed lever 4231 to exert a force to connection pole 4232, connect armed lever 4231 to reduce with the angle be connected between pole 4232, thus making the second rotating shaft 422 be rotated counterclockwise certain angle, the first heald frame 21 be connected with the second rotating shaft 422 rises, and the second heald frame 22 declines.In like manner, when the second drive rotor 4211 of impeller 421 is promoted by the first cam 4201 of conjugate cam 420, the second rotating shaft 422 resets clockwise, and the first heald frame 21 declines, and the second heald frame 22 rises.Thus making the first heald frame 21 and the second heald frame 22 realize longitudinally upper reciprocating motion, structure and the kind of drive is simple, energy-conserving and environment-protective, is suitable for practical.
