Description

Jacquard jacquard device of piezoelectric ceramic and warp knitting machine

Technical Field

The invention relates to the field of warp knitting machines, in particular to a jacquard device of piezoelectric ceramics and a warp knitting machine.

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.

The working principle of the circuit is as follows: the piezoelectric ceramic plate of Gu Kazhong belongs to a capacitive element, and is essentially two capacitors, after the piezoelectric ceramic plate is charged, the piezoelectric ceramic plate can deform under the action of a piezoelectric effect, so that the piezoelectric ceramic plate swings left and right, the piezoelectric ceramic plate equivalent circuit is arranged below, the middle part of the piezoelectric ceramic plate equivalent circuit is grounded to charge or discharge the two capacitors respectively, the piezoelectric ceramic plate swings, and the piezoelectric ceramic plate has the advantages that only one of the two capacitors can be in a charging state at the same time, and the other capacitor is in a non-electric state (the voltage at two ends of the capacitor is 0), which is determined by the current working principle of the piezoelectric ceramic plate. Therefore, the driving circuit is essentially a circuit for charging and discharging the equivalent capacitance of the piezoelectric ceramic plate.

The left and right sides are respectively provided with a driving circuit, the structures of the two driving circuits are identical, and in order to facilitate the explanation of the working principle, only a single driving circuit is explained later.

Referring to fig. 6, within the dashed box is a driving circuit equivalent schematic, and each point is described as follows:

1. the equivalent capacitance C1 is an equivalent capacitance of the piezoelectric ceramic sheet (see fig. 6 and 7).

2. The power supply VCC is a jacquard-driven dc voltage source.

3. The electronic switch K1 and the electronic switch K2 are electronic switches, have on and off states and are controlled by corresponding high/low levels of the AND gates.

4. And an AND gate U1 and an AND gate U2 (or other equivalent circuit gates) are respectively arranged in front of the electronic switch, each AND gate is provided with two input ends, one input end is connected to a PWM signal source (square wave signal source) in parallel, and the other end is connected to a jacquard control signal S1 and a jacquard control signal S2. The output is used for controlling the electronic switch K1, the electronic switch K2 is on and off, in the circuit, according to popular convention, the AND gate outputs a high level (=1) to represent that the switch is on, and a low level (=0) to represent that the switch is off.

5. The PWM signal source is a square wave signal source which outputs square wave signals with certain frequency and duty ratio for supporting the work of the whole circuit

The following describes how the driving circuit operates and has an energy saving effect. 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.

Referring to fig. 6, 7 and 8, the equivalent capacitance C1 charging process:

1: a set control signal jacquard control signal s1=1; the jacquard control signal s2=0, at this time, the output of the and gate U1 is the output waveform of the PWM signal source, and the signal input terminal=0 of the and gate U2, and the output of the and gate U2 is constant to 0 according to the characteristics of the and gate, and is not affected by the PWM signal source.

2: the electronic switch K1 is controlled by the AND gate U1, the AND gate U1 outputs a PWM signal source signal, and the AND gate U1 controls the electronic switch K1 to conduct the on-off action along with the square wave height change of the PWM signal source.

3: when the electronic switch K1 is turned on, the freewheeling diode D2 is reversely biased, the electronic switch K2 is cut off, and the power supply VCC is applied to the inductor L1 and the equivalent capacitor C1 through the electronic switch K1; when the electronic switch K1 is turned on, the voltage at two ends of the inductor L1=the power VCC, and the electronic switch K1 itself does not bear the power voltage; along with the extension of the on time of the electronic switch K1, the current of the inductor L1 is increased, the voltage of the end of the inductor L1 is reduced, and under the condition that the voltage of the end of the inductor L1 is not reduced much, the electronic switch K1 enters a cut-off state under the control of a PWM signal source; due to the inductance characteristic, the current direction of the inductor L1 is unchanged, the equivalent capacitor C1 is continuously charged, and the freewheeling diode D2 is turned on.

Along with the continuous conduction and cutoff of the electronic switch K1 under the control of the PWM signal source, the voltage at two ends of the equivalent capacitor C1 finally reaches the voltage of the power supply VCC, and the charging action of the equivalent capacitor C1 is completed. In this process, the electronic switch K1 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 K1 itself is small.

Referring to fig. 7, 9 and 10, the equivalent capacitance C1 discharge process:

1: the control signal, the jacquard control signal s1=0, the jacquard control signal s2=1, and the signal input terminal jacquard control signal s1=0 of the and gate U1 according to the and gate characteristics, so that the output of the and gate U1 is constant to 0. The signal input terminal=1 of the and gate U2, and the output of the and gate U2 is the output waveform of the PWM signal source according to the characteristics of the and gate, and the control process is the same as the above.

2: since the electronic switch K2 is controlled by the and gate U2, the electronic switch K2 is operated in the on-off state under the control of the PWM signal source. Because of the previous charging action of the electronic switch K1, the point a is the charging positive electrode of the equivalent capacitor C1 (one end of the equivalent capacitor C1 is the point a), and the point a refers to reference sign a in fig. 7, 8, 9 and 10, when the electronic switch K2 is turned on, the equivalent capacitor C1 will discharge through the inductor L1 and the electronic switch K2; in the discharging process, due to the characteristics of the inductor, when the electronic switch K2 is turned on, the charging voltage of the equivalent capacitor C1 is borne by the inductor L1, that is, the voltage at the end of the inductor L1 is equal to the charging voltage of the equivalent capacitor C1, and the voltage at the end of the electronic switch K2 is 0. Along with the extension of the on time of the electronic switch K2, the current of the inductor L1 is increased, the voltage of the end of the inductor L1 is reduced, and under the condition that the voltage of the end of the inductor L1 is not reduced much, the electronic switch K2 enters a cut-off state under the control of a PWM signal source; because of the inductance characteristic, the current direction of the inductance L1 is unchanged, and the current is returned to the power supply VCC through the freewheeling diode D1, namely, under the combined action of the electronic switch K2, the inductance L1 and the freewheeling diode D1, the energy stored before the equivalent capacitor C1 is returned to the power supply.

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.

In the whole working process, the electronic switch K1 and the electronic switch K2 are always in lower loss in the working process, so that the efficiency is greatly improved, and the heating degree of the driving circuit is effectively reduced.

The electronic switch K1 can be a switch circuit composed of a triode and an MOS tube. The electronic switch K2 can be a switch circuit composed of a triode and an MOS tube.
