Description

TECHNICAL FIELD

[0001] The present application relates to the field of warp knitting machines, in particular to a piezoelectric ceramic jacquard device and a warp knitting machine. BACKGROUND

[0002] The piezoelectric jacquard is composed of a piezoelectric selection needle, a gripper end, a guide needle, a protective cover, a cable plug, and an aluminum-magnesium alloy base for fixing and limiting the piezoelectric selection needle. The piezoelectric selection needle is composed of a piezoelectric ceramic-base plate-insulating glass fiber layer-piezoelectric ceramic three-layer structure. By applying positive and negative voltages alternately to both sides of the piezoelectric jacquard element through the jacquard driver, the piezoelectric ceramic is bent, thereby enabling the guide needle to deviate to the left or right. When positioning blocks are arranged on both sides of the guide needle, the deviation angle can be accurately controlled. Because the piezoelectric ceramic has a capacitive effect, the piezoelectric jacquard element can remain in its deviated position.

[0003] A conventional single jacquard is composed of a base and a ceramic sheet. The key structure is that a row of piezoelectric ceramic sheets is installed horizontally on the single base according to the specified interval. In terms of application, multiple jacquards are arranged horizontally and installed on the gripper mounting part. Typically, a complete jacquard application is composed of two gripper mounting parts, and the jacquards on each gripper mounting part correspond to odd and even needle positions. The reason for dividing the complete jacquard application into two groups is illustrated by an E24 needle spacing jacquard: the needle spacing of each needle of E24 is 1.058 mm, and the thickness of the piezoelectric ceramic sheet has reached 0.8 mm. Obviously, it is impossible to place the piezoelectric ceramic sheet in such an interval on a single base. Therefore, the odd and even needle positions of the E24 ceramic sheet with a spacing of 1.058 needle spacing are extracted and divided into two groups. Then, the needle spacing of the jacquard column with only odd or even rows is doubled to 2.116 mm, and the ceramic sheet of the current thickness can be placed in such a distance. Therefore, in fact, a complete jacquard needle application is composed of odd and even rows of needles on two gripper mounting parts, and the odd and even rows are staggered by one needle during installation, thereby forming a complete jacquard application.

[0004] A complete single jacquard application (odd and even each 1 = 2 gripper mounting parts), i.e., a single jacquard application, if it is two groups (odd and even each 2 = 4 gripper mounting parts), i.e., a double jacquard application, and so on. Then, the current jacquard situation is that only one row of piezoelectric ceramic sheets is distributed on each base, and multiple horizontally distributed bases only increase the total number of the row of piezoelectric ceramic sheets, but the total is still one row (layer). The odd and even groups of horizontally distributed jacquards are two rows, but the two rows are separated.

[0005] In the prior art, the double-jacquard warp knitting machine has two pattern units composed of piezoelectric jacquard bars. In the existing jacquard pattern device, a bottom base needs to be arranged to install the piezoelectric jacquard element, and then the jacquard pattern device is arranged on the bar mounting part. One pattern unit has two rows of bar mounting parts and two rows of bottom bases, which makes the double-jacquard warp knitting machine have four rows of bar mounting parts and four rows of bottom bases, and the triple-jacquard warp knitting machine has six rows of bar mounting parts and six rows of bottom bases (for details, refer to Chinese Utility Model Patent (Application No. 202121809958.7, Publication No. CN216040097U) which discloses a triple-jacquard double needle bed warp knitting machine, Chinese Utility Model Patent (Application No. 201520456123.6, Publication No. CN204849251U) which discloses a double-jacquard warp knitting machine with a presser board, and Chinese Utility Model Patent (Application No. 201520456123.6, Publication No. CN204849251U) which discloses an eight-bar double-jacquard bar arrangement and swing mechanism).

[0006] However, the bar mounting part and the bottom base only play a connecting and mounting role. In the case of narrow installation space in the bar mounting part rocker, the space is occupied, which affects the distance between the two jacquard bars. These redundant bar mounting parts and bottom bases occupy space and increase the weight of the jacquard bar. SUMMARY

[0007] The present application provides a piezoelectric ceramic jacquard pattern device and a warp knitting machine, which mainly aims to overcome the defect that the existing jacquard pattern device only has a row of piezoelectric jacquard elements for pattern yarn guiding.

[0008] To solve the above technical problems, the present application adopts the following technical solutions:

[0009] A piezoelectric ceramic jacquard pattern device, comprising at least one mounting part and a plurality of execution parts arranged on the mounting part, one side of the mounting part has a plurality of first mounting grooves arranged, the other side of the mounting part has a plurality of second mounting grooves arranged, the execution part includes a plurality of first piezoelectric jacquard elements and a plurality of nth piezoelectric jacquard elements, a part of each first piezoelectric jacquard element is arranged on the first mounting groove, the other part of the first piezoelectric jacquard element is used to realize pattern yarn guiding in the form of independent swing left and right, a part of each nth piezoelectric jacquard element is arranged on the second mounting groove, and the other part of the nth piezoelectric jacquard element is used to realize pattern yarn guiding in the form of independent swing left and right.

[0010] A warp knitting machine, comprising at least one jacquard pattern device, the jacquard pattern device being the above jacquard pattern device.

[0011] Compared with the prior art, the present application has the beneficial effects that:

[0012] The present application has the advantages of simple structure and strong practicability. By arranging the first piezoelectric Jacquard element on the first mounting groove and the nth piezoelectric Jacquard element on the second mounting groove, the first piezoelectric Jacquard element and the nth piezoelectric Jacquard element are respectively arranged on one side and the other side of one mounting part, the structure is compact, when the Jacquard device is installed on the warp knitting machine, the space occupied by one mounting part of one row is reduced, only one mounting part of one row is used to realize the effect of installing two rows of piezoelectric Jacquard elements, the cost of one row of mounting parts is saved, and the integration of the Jacquard device is improved.

[0013] In the present application, by arranging the first piezoelectric Jacquard element on the first mounting groove and the nth piezoelectric Jacquard element on the second mounting groove, the integration of the Jacquard device is improved, so that the Jacquard device can well meet the use requirements of the double-Jacquard warp knitting machine.

[0086] Circuit working principle: the piezoelectric ceramic piece in the jaka itself belongs to capacitive element, its nature is two capacitors, after charging the piezoelectric ceramic piece, under the action of piezoelectric effect, the piezoelectric ceramic piece itself will change, thus left and right swing, the following is the equivalent circuit of piezoelectric ceramic piece, the middle part is grounded, respectively charge or discharge of the two capacitors, piezoelectric ceramic piece will swing, it should be noted that, the two capacitors at the same time only one is in charging state, the other is no electricity (the voltage across the capacitor is 0), this is the working principle of piezoelectric ceramic piece at present determines. Therefore, the driving circuit is essentially a charging and discharging circuit for the equivalent capacitor of piezoelectric ceramic piece.

[0087] There are two driving circuits on the left and right sides, and their structures are exactly the same. In order to facilitate the explanation of the working principle, only a single driving circuit will be described in the following.

[0088] Reference Figure 7 The dashed box is the equivalent schematic diagram of the driving circuit, and each point is described as follows:

[0089] 1. The equivalent capacitor C1 is the equivalent capacitor of the piezoelectric ceramic piece (refer to Figure 6 and Figure 7 ).

[0090] 2. The power supply VCC is a jaka driving DC voltage source.

[0091] 3. Electronic switch K1 and electronic switch K2 are electronic switches, which have two states of on and off, controlled by the corresponding AND gate high / low level.

[0092] 4. Before the electronic switch, there are AND gate U1 and AND gate U2 (or other equivalent function circuit gate) respectively. Each AND gate has two input ends, one of which is connected in parallel to a PWM signal source (square wave signal source), and the other end is connected to the jaka control signal S1 and S2. The output is used to control the on / off state of the electronic switch K1 and K2. In this circuit, according to the popular convention, the high level (=1) of the AND gate output represents the on state of the switch, and the low level (=0) represents the off state of the switch.

[0093] 5. The PWM signal source is a square wave signal source, which outputs a square wave signal of a certain frequency and duty cycle to support the operation of the entire circuit

[0094] The following describes how the driving circuit works and achieves energy saving effect. As mentioned earlier, the driving process of the piezoelectric ceramic piece is essentially a charging and discharging process of the equivalent capacitor C1. The following describes the working process of the circuit. In order to facilitate the description, it is assumed that the equivalent capacitor C1 is in no electricity state at this time.

[0095] Reference Figure 8 , Figure 7And Figure 9 , equivalent capacitor C1 charging process:

[0096] 1: set control signal, Jack control signal S1 = 1; Jack control signal S2 = 0, at this time the output of the AND gate U1 is the output waveform of the PWM signal source, the signal input end of the AND gate U2 = 0, according to the characteristics of the AND gate, at this time the output of the AND gate U2 is constant 0, not affected by the PWM signal source.

[0097] 2: electronic switch K1 is controlled by the AND gate U1, the AND gate U1 outputs the PWM signal source signal, the AND gate U1 controls the electronic switch K1 to conduct and cut off according to the high and low of the PWM signal source square wave.

[0098] 3: when the electronic switch K1 is turned on, the freewheeling diode D2 is reversed biased, the electronic switch K2 is cut off, the power supply VCC passes through the electronic switch K1 and is applied to the inductor L1 and the equivalent capacitor C1; when the electronic switch K1 is turned on, the voltage across the inductor L1 = the power supply VCC, the electronic switch K1 itself does not bear the power supply voltage; as the time of the electronic switch K1 being turned on increases, the current of the inductor L1 increases and the voltage across the inductor L1 decreases, under the condition that the voltage across the inductor L1 does not decrease much, the electronic switch K1 enters the cut-off state again under the control of the PWM signal source; due to the inductance characteristic, the current direction of the inductor L1 does not change and the freewheeling diode D2 is turned on.

[0099] As the electronic switch K1 is continuously turned on and cut off under the control of the PWM signal source, the voltage across the equivalent capacitor C1 will eventually reach the voltage of the power supply VCC, completing the charging action of the equivalent capacitor C1. In this process, due to the existence of the inductor L1, the electronic switch K1 has current but no voltage when turned on and has voltage but no current when cut off, and works in a switching state under the control of the PWM signal source, so the average loss of the electronic switch K1 itself is small.

[0100] Referring to Figure 10 , Figure 7 and Figure 8 , equivalent capacitor C1 discharging process:

[0101] 1: set control signal, Jack control signal S1 = 0, Jack control signal S2 = 1, according to the characteristics of the AND gate, the signal input end of the AND gate U1 Jack control signal S1 = 0, so at this time the output of the AND gate U1 is constant 0. The signal input end of the AND gate U2 = 1, according to the characteristics of the AND gate, at this time the output of the AND gate U2 is the output waveform of the PWM signal source, and the control process is the same as above.

[0102] 2: Since the electronic switch K2 is controlled by the AND gate U2, the electronic switch K2 is in the switching state under the control of the PWM signal source. Due to the charging action of the electronic switch K1, the point A is the positive terminal of the equivalent capacitor C1 (one end of the equivalent capacitor C1 is the point A), and the position of the point A is referred to as the reference Figure 9 , Figure 10 , Figure 9 and Figures 1-5 the equivalent capacitor C1 will be discharged through the inductor L1 when the electronic switch K2 is turned on; during the discharging process, due to the characteristics of the inductor, the charging voltage of the equivalent capacitor C1 will be borne by the inductor L1 when the electronic switch K2 is turned on, 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 across the electronic switch K2 is 0. As the time of the electronic switch K2 being turned on increases, the current of the inductor L1 increases, and the voltage at the end of the inductor L1 decreases. In the case that the voltage at the end of the inductor L1 does not decrease much, the electronic switch K2 enters the cutoff state again under the control of the PWM signal source; due to the characteristics of the inductor, the current direction of the inductor L1 does not change, and the current will be returned to the power supply VCC through the freewheeling diode D1, that is, under the joint action of the electronic switch K2, the inductor L1 and the freewheeling diode D1, the energy stored in the equivalent capacitor C1 will be returned to the power supply.

[0103] With the electronic switch K2 being turned on and cut off under the control of the PWM signal source, the voltage across the equivalent capacitor C1 will eventually decrease to 0, and the discharging action of the equivalent capacitor C1 will be completed. In this process, due to the existence of the inductor L1, the electronic switch K2 has current but no voltage when it is turned on, and has voltage but no current when it is cut off. The electronic switch K2 works in the switching state under the control of the PWM signal source, so the average loss of the electronic switch K2 itself is small.

[0104] In the entire working process, the electronic switch K1 and the electronic switch K2 are always in a low loss state during the working process, and the efficiency is greatly improved, effectively reducing the heat generation of the driving circuit.

[0105] The electronic switch K1 can be a switching circuit composed of a transistor and a MOS tube. The electronic switch K2 can be a switching circuit composed of a transistor and a MOS tube.

[0106] The circuit of the other half of the piezoelectric ceramic sheet and the charging and discharging working principle are exactly the same as above, so they will not be described again.
