Description

Technical Field

[0001] This invention relates to the field of warp knitting machines, and in particular to a control method for a jacquard driver, a wireless jacquard, and a warp knitting machine. Background Technology

[0002] Current wireless jacquards generally use electrical signals for data exchange or communication control, and are connected to signal lines through various types of connectors.

[0003] Chinese invention patent (application number: 202111645009.4, publication number: CN114232199B) discloses a piezoelectric jacquard mounting assembly, including multiple piezoelectric jacquards and a comb connected to the multiple piezoelectric jacquards. Each piezoelectric jacquard is provided with a drive circuit board for driving the piezoelectric jacquard, and multiple conductive contacts are connected at the electrical connection point on the lower side of the drive circuit board.

[0004] During long-term operation, the exposed conductive contacts oxidize faster due to heat generation. Or, during routine disassembly and maintenance, the exposed conductive contacts may become contaminated with pollutants, which can affect the transmission of electrical signals and the lifespan of the wireless jacquard. This results in a situation where electromagnetic interference is relatively complex, requiring a higher level of anti-interference capability for the entire circuit. Summary of the Invention

[0005] This invention provides a control method for a jacquard driver, a wireless jacquard, and a warp knitting machine. Its main purpose is to overcome the defect that the transmission of pattern process data will be affected after long-term use of the conductive metal of the jacquard driver due to contamination of the metal surface or oxidation by oxygen in the air, thereby affecting the service life of the jacquard.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: In a first aspect, this disclosure provides a control method for a Jacquard driver, the control method comprising: In response to the first optical receiver acquiring a first optical signal carrying floral process data, the first optical receiver sends a first electrical signal matching the first optical signal to the corresponding driving circuit. The first optical receiver sends a first electrical signal containing pattern process data to the second optical transmitter. The first electrical signal is based on the pattern process data. The second light emitter emits a second light signal, which carries pattern process data.

[0007] In one possible implementation, the second optical receiver acquires a third optical signal carrying floral pattern process data, and the second optical receiver sends a third electrical signal matching the third optical signal to the corresponding driving circuit. The second optical receiver sends a third electrical signal containing pattern process data to the first optical transmitter. The third electrical signal is based on the pattern process data. The first optical transmitter emits a fourth optical signal, which carries floral pattern process data.

[0008] In one possible implementation, the driving circuit outputs a second electrical signal to the corresponding piezoelectric ceramic sheet based on the pattern process data corresponding to the first electrical signal. The second electrical signal is used to control the deformation of the corresponding piezoelectric ceramic sheet.

[0009] In one possible implementation, the pattern process data is configured as one of the following: the communication address value of the corresponding wireless jacquard, the injection signal, or the bit stream data.

[0010] In one possible implementation, the first electrical signal transmits pattern process data in a high-level and low-level manner, and the second electrical signal transmits pattern process data in a high-level and low-level manner.

[0011] In one possible implementation, the first optical signal transmits pattern process data in terms of light intensity, frequency, or phase, and the second optical signal transmits pattern process data in terms of light intensity, frequency, or phase.

[0012] Secondly, this disclosure provides a jacquard driver, comprising: The first optical receiver is used to acquire a first optical signal carrying floral process data and send a first electrical signal matching the first optical signal to the corresponding driving circuit. The first optical receiver sends a first electrical signal carrying the pattern process data to the optical transmitter, the first electrical signal being based on the pattern process data; A second light emitter is used to emit a second light signal, which carries the flower pattern process data.

[0013] In one possible implementation, a second optical receiver is used to acquire a third optical signal carrying pattern process data, and the second optical receiver sends a third electrical signal matching the third optical signal to a corresponding driving circuit. The second optical receiver sends a third electrical signal containing pattern process data to the first optical transmitter. The third electrical signal is based on the pattern process data. The first optical transmitter is used to transmit a fourth optical signal, which carries pattern process data.

[0014] Thirdly, this disclosure provides a wireless Jacquard, which has a Jacquard yarn guide needle block and a Jacquard driver. The Jacquard driver uses the control method described above to control the Jacquard driver, so that the driving circuit of the Jacquard driver drives the piezoelectric ceramic sheet of the Jacquard yarn guide needle block to deform according to the first electrical signal, thereby driving the yarn guide needle to swing.

[0015] Fourthly, this disclosure provides a warp knitting machine having at least two wireless jacquards. The wireless jacquards include jacquard guide needle blocks and jacquard drivers. The jacquard drivers are controlled by the control method described above. When the two wireless jacquards are close together, the second optical signal emitted by the optical transmitter of one jacquard driver is received by the optical receiver of the other adjacent jacquard driver to form a complete optical communication loop.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention has a simple structure and strong practicality. By setting up a first optical communication circuit consisting of a first optical receiver, a driver circuit board, and a second optical transmitter, a portion of the exposed conductive contacts are replaced. Data is transmitted using the first optical communication circuit, which improves the stability of data transmission and extends the service life of the wireless jacquard.
