Description

Jacquard jacquard device of piezoelectric ceramics

Technical Field

The utility model relates to the field of warp knitting machines, in particular to a jacquard device of piezoelectric ceramics.

Background

The piezoelectric jacquard consists of a piezoelectric needle selecting piece, a guide bar holding end, a yarn guiding needle, a protective cover, a cable plug, an aluminum magnesium alloy base used for fixing and limiting the piezoelectric needle selecting piece, and the like, wherein the piezoelectric needle selecting piece consists of a piezoelectric ceramic-substrate (an insulating glass fiber layer) -piezoelectric ceramic three-layer structure. The positive and negative voltages are alternately applied to the two sides of the piezoelectric jacquard element through the jacquard driver, so that the piezoelectric ceramics are bent, and the yarn guide needle can be shifted leftwards or rightwards. When the positioning blocks are arranged at the two sides of the yarn guide needle, the offset angle of the yarn guide needle can be accurately controlled. And because the piezoelectric ceramic has the effect like a capacitor, the piezoelectric jacquard element can be kept at the offset position.

The conventional single jacquard consists of a base seat and ceramic plates, and the structural key point is that: a row of piezoelectric ceramic plates are horizontally arranged on a single base at specified intervals to form a jacquard. On the application level, a plurality of jacquard cards are horizontally arranged and installed on the guide bar installation parts, and in general, the complete jacquard card application consists of two guide bar installation parts, and each jacquard card on each guide bar installation part corresponds to an odd number needle position and an even number needle position. The complete jacquard applications are divided into two groups, the reason for which is illustrated by the jacquard of the E24 pitch: the needle pitch of each needle of E24 is 1.058mm, the thickness of the piezoelectric ceramic sheet is 0.8mm, and obviously, in the interval, the piezoelectric ceramic sheet cannot be placed on a single base, so that the odd and even needle positions of the E24 ceramic sheet with the 1.058 needle pitch are extracted and divided into two groups. Then, the pitch of Gu Kalie, which is an odd or even number of lines alone, is doubled to 2.116mm, and the ceramic sheet with the current thickness can be placed at the distance. Therefore, in practice, the application of a complete jacquard needle is composed of odd-numbered rows of needles and even-numbered rows of needles on the mounting parts of two guide bars, and when the jacquard needle is mounted, the odd-numbered rows and the even-numbered rows are staggered by 1 needle, so that the complete jacquard needle is formed.

A complete set of Shan Guka applications (parity of 1=2 bar installations), shan Guka applications, two sets (parity of 2=4 bar installations), double Gu Kaying applications, and so on. The current jacquard situation is then that only one row of piezoelectric ceramic plates is distributed on each base, and that the plurality of horizontally distributed bases only increases the overall number of piezoelectric ceramic plates of the row, but always one row (layer). The even and odd sets of horizontally arranged jacquard cards are two rows, but the two rows are separated.

In the prior art, a double jacquard warp knitting machine has two jacquard units composed of piezoelectric jacquard bars, and in the existing jacquard device, a base seat is required to be provided for mounting piezoelectric jacquard elements, and then the jacquard device is mounted on a bar mounting part. A jacquard unit has two courses of bar mounting portions and two courses of base, which makes it possible to provide a double jacquard warp knitting machine with four courses of bar mounting portions and four courses of base, and a triple jacquard warp knitting machine with six courses of bar mounting portions and six courses of base (concretely, refer to, chinese patent application No. 202121809958.7, publication No. CN 216040097U) discloses a triple Gu Kashuang needle bar warp knitting machine, chinese patent application No. 201520456123.6, publication No. CN204849251U discloses a double jacquard warp knitting machine with a presser plate, chinese patent application No. 201520456123.6, publication No. CN204849251U discloses an eight-bar double jacquard comb arrangement and swing mechanism).

However, the bar mounting portion and the base seat both only play a role in connection and mounting, and under the condition that the mounting space in the bar mounting portion cradle is small, the space between two jacquard bars is influenced by the space, and the redundant bar mounting portion and the base seat both occupy space, so that the weight of the jacquard bars is increased.

Therefore, the driving circuit is essentially a circuit for charging and discharging the equivalent capacitance of the piezoelectric ceramic plate.

The foregoing description has already described that the driving process of the piezoelectric ceramic plate is essentially the charging and discharging process of the equivalent capacitor C1, and the following description describes the working process of the circuit, and for convenience of description, it is assumed that the equivalent capacitor C1 is in the no-power state at this time.

Along with the continuous conduction and cutoff of the electronic switch K2 under the control of the PWM signal source, the voltage at two ends of the equivalent capacitor C1 can be reduced to 0 finally, and the discharging action of the equivalent capacitor C1 is completed. In this process, the electronic switch K2 has a current but no voltage when turned on and a voltage but no current when turned off due to the presence of the inductor L1, and operates in a switching state under the control of the PWM signal source, so that the average loss of the electronic switch K2 itself is small.
