On griffe the connection hole one that 9 two ends offer be set in respectively upper left griffe connection section one 8b of arm 8 and upper right griffe arm 8 connection section one 8b on, thus griffe on driving 9 to slide up and down within the specific limits simultaneously, and griffe on realizing 9 dismantled setting; Under griffe the connection hole two that 12 two ends offer be set in respectively lower-left griffe connection section two 11b of arm 11 and bottom right griffe arm 11 connection section two 11b on, thus griffe 12 to slide up and down within the specific limits under driving simultaneously, and griffe on realizing 9 dismantled setting.
In addition, transmission shaft 18 is also provided with the drives structure that it can be driven to rotate. More particularly, drives structure comprises drive-motor 33, drive sprocket 34, driven sprocket wheel 35 and chain 36, drive-motor 33 is fixed in frame 1, drive sprocket 34 is fixed on the output shaft of drive-motor 33, driven sprocket wheel 35 is fixed on one end of above-mentioned transmission shaft 18, and drive sprocket 34 and driven sprocket wheel 35 are all in same plane, chain 36 is arranged between drive sprocket 34 and driven sprocket wheel 35. Drive-motor 33 drives drive sprocket 34 to rotate, then drives driven sprocket wheel 35 to rotate by chain 36, thus realizes the rotation of transmission shaft 18.
Summary, generally speaking the principle of work of this jacquard machine is such:
1, starting drive-motor 33, the output shaft of drive-motor 33 drives drive sprocket 34 to rotate, then drives driven sprocket wheel 35 to rotate by chain 36, thus realizes the rotation of transmission shaft 18;
2, transmission shaft 18 drives left eccentric wheel 19 to rotate, owing to the core wheel line on the hole heart line in hole eccentric on left eccentric wheel 19 and left eccentric wheel 19 exists potential difference, it is thus possible to make left rocking bar 21 make reciprocating rotation by predetermined path of movement, thus realize upper left and griffe frame 4, lower-left and griffe frame 5 and up and down reciprocatingly move;
3, transmission shaft 18 drives right eccentric wheel 20 to rotate simultaneously, owing to the core wheel line on the hole heart line in hole eccentric on right eccentric wheel 20 and right eccentric wheel 20 exists potential difference, and on right eccentric wheel 20 there is the potential difference of 180 �� with the hole heart line in bias hole on left eccentric wheel 19 in the hole heart line in eccentric hole, it is thus possible to make right rocking bar 24 make reciprocating rotation by predetermined path of movement, thus realize bottom right and griffe frame 7, upper right and griffe frame 6 and up and down reciprocatingly move;
4, drive upper left to griffe frame 4 and lower-left is griffed frame 5 and slided up and down in through hole one 2a of left support plate 2 respectively by slide block 1 and slide block 2 15, drive upper right to griffe frame 6 and bottom right is griffed frame 7 and slided up and down in through hole two 3a of right support plate 3 respectively by slide block 3 16 and slide block 4 17;
5, griffing frame 4 by upper left and upper right griffes the sliding up and down of frame 6, drive griffes arm 8 to be slided up and down, thus the upper jacquard needle 10 griffed on realizing on 9 slides up and down;
6, simultaneously, griffing frame 5 by lower-left and the sliding up and down of frame 7 is griffed in bottom right, griffing arm 11 under drive slides up and down, thus the lower jacquard needle 13 griffed under realizing on 12 slides up and down;
7, jacquard fabric is finally woven.
