In the embodiment, the piezoelectric jacquard device realizes the working principle of three stations:

the swing amplitude of the double-station piezoelectric jacquard device is a slot needle position, and the swing amplitude of the three-station piezoelectric jacquard device is two slot needle positions (two needle pitches) due to the addition of a station state, namely: without traversing, its swing is two grooved pins (two pitches).

Referring to fig. 4, the three-position piezoelectric jacquard device refers to a device in which the yarn guide 17 can accurately stop at the intermediate position (refer to the second position 21) in addition to swinging left and right.

Referring to fig. 4, the piezoelectric jacquard device of the duplex position can only swing left and right, the parking position is fixed and accurate, the fixing and accurate is that after the tooth groove 23 of the bottom base 110 is grooved according to the calculated data, the left swing or the right swing of the yarn guide needle 17 can be stopped on the tooth wall, and the needle position is correct as long as the tooth wall distance is correct because the tooth wall distance is calculated. The piezoelectric ceramic plates can generate swinging moment after being charged, the complete piezoelectric ceramic plates capable of swinging left and right are formed by bonding two single piezoelectric ceramic plates on a glass fiber plate in a combined mode, each single piezoelectric ceramic plate is responsible for one swinging direction, namely one single piezoelectric ceramic plate is charged and the other single piezoelectric ceramic plate is discharged, namely correct swinging moment can be generated, and the piezoelectric ceramic plates swing leftwards or rightwards, which is the basic swinging principle of the piezoelectric ceramic plates.

Referring to fig. 4, after the second piezoceramic sheet 13 is disposed, when the barrier sheet 9 at the front end of the second piezoceramic sheet 13 is operated, the barrier sheet 9 falls into the second recess 233 because the bottom of the barrier sheet 9 is lower than the second limit portion, and the barrier sheet 9 is blocked by the second limit portion and the third limit portion when swinging, so that the upper portion of the barrier sheet 9 is limited to swing only left and right in the first recess 232, and because the first recess 232 is disposed to have the width of two pitches, the barrier sheet 9 can swing left and right in the first recess 232 by one pitch due to the blocking of the second limit portion. Since the second limiting portion limits the blocking piece 9, the blocking piece 9 can only swing between the second limiting portion and the third limiting portion.

Referring to fig. 4 and 6, the second piezoelectric ceramic sheet 13 is provided longer in order to increase the moment of the second piezoelectric ceramic sheet 13, and the moment of the second piezoelectric ceramic sheet 13 is greater than the moment of the first piezoelectric ceramic sheet 14 due to the need to implement three working positions.

Embodiment five, referring to fig. 5 and 6, is different from embodiment one in that: the piezoelectric jacquard device further comprises at least one mounting part 31 arranged between the first mounting groove 10 and the second mounting groove 11, wherein when the second piezoelectric ceramic element 7 is arranged above the piezoelectric jacquard element 6 in a laminated mode, the mounting part 31 is used for mounting a power supply device for supplying power to the piezoelectric jacquard element 6, and when the piezoelectric jacquard element 6 is arranged above the second piezoelectric ceramic element 7 in a laminated mode, the mounting part 31 is used for accommodating a part of the second piezoelectric ceramic element 7.

Referring to fig. 5 and 6, the power supply device (not shown in the drawings) includes a first connector detachably mounted on the bottom base 110, a first cable at least a portion of which is disposed in the first connector, a second connector detachably mounted on the bottom base 110, and a second cable at least a portion of which is disposed in the second connector, wherein an output end of the first cable is electrically connected with the first electrical connection end 16, an input end of the first cable is electrically connected with an external driving circuit board, a driving circuit is disposed on the driving circuit board and can drive the first piezoelectric ceramic sheet 14 to swing, an output end of the second cable is electrically connected with the second electrical connection end 33, and an input end of the second cable is electrically connected with the external driving circuit board, and a driving circuit is disposed on the driving circuit board and can drive the second piezoelectric ceramic sheet 13 to swing.

The piezoelectric ceramic piece (first piezoelectric ceramic piece 14) used in the baffle 9 has a moment larger than that of the piezoelectric ceramic piece (second piezoelectric ceramic piece 13) of the yarn guide needle by at least 1 time, and the following reasons are explained: when the piezoelectric ceramic plate of the yarn guide needle is confined to the intermediate position, it is not moment-free itself, and if it is moment-free it is pulled by the yarn to cause displacement of the needle position, so that when the piezoelectric ceramic plate of the yarn guide needle is in the intermediate position there will be a moment that will cause the needle head to press against the catch 9, assuming a moment of 10 g. At this time, if the moment of the piezoelectric ceramic sheet with the blocking piece 9 is also 10 g, the moment is offset due to the opposite directions, and the movement is performed toward the blocking piece 9 under the pulling of the yarn (the moment of the needle+the pulling force of the yarn >10 g), so that the blocking piece 9 cannot be fixed in position, and the needle position is also shifted. At this time, if the moment of the blocking piece 9 is large (at least 1 time), the needle will not shift in both directions, so that the needle can be stabilized in the middle position. For this reason, the piezoelectric ceramic plate of the blocking piece 9 is longer than the piezoelectric ceramic plate of the yarn guide needle, and the longer moment of the piezoelectric ceramic plate is larger.
