Abstract
Description
Technical Field
[0001] This utility model relates to the field of warp knitting machines, and in particular to an integrated jacquard device and a warp knitting machine. Background Technology
[0002] Warp knitting machines require multiple Jacquard combs. Currently, the main controller connects to the corresponding Jacquard combs via connectors, and the Jacquard combs are interconnected via connectors. The main controller sends process data via an optical signal communicator. Since the process data is sent sequentially, there is a certain order in the transmission process. Assume the first data corresponds to Jacquard comb number 1, the second data corresponds to Jacquard comb number 2, and so on. The Jacquard combs receive the entire process data from the optical signal communicator, including the process data for all Jacquard combs. Therefore, when a Jacquard comb receives process data, it needs an identifier to recognize which data corresponds to it. Thus, each Jacquard comb needs an address code to ensure that the first data corresponds to Jacquard comb number 1.
[0003] The Jacquard combs are arranged sequentially, with the actual address sequence starting from the main controller side: the first Jacquard comb is address 1, the second Jacquard comb is address 2, and so on. Currently, a common method for handling Jacquard comb addresses is to install DIP switches on the combs. The first Jacquard comb has its DIP switch set to 1, and the second Jacquard comb is set to 2. The advantage of this method is its versatility; however, in practical use, it has the following drawbacks: multiple Jacquard combs are connected via a communication bus for quick address setting. However, if the communication bus is placed alongside the power line, it is susceptible to electromagnetic interference, which can affect the transmission of process data. Utility Model Content
[0004] This utility model provides an integrated jacquard knitting device and a warp knitting machine. Its main purpose is to overcome the problem that when the communication bus and the power line are set together, the communication bus is easily affected by electromagnetic interference, which affects the transmission of process data.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] In a first aspect, this disclosure provides an integrated jacquard fabrication device, comprising:
[0007] Jacquard comb;
[0008] The processor is integrated into the Jacquard comb;
[0009] A first power interface is located on one side of the Jacquard comb, and the first power interface is electrically connected to the processor via a power cable; and
[0010] An optical signal communicator has an optical signal receiver for receiving a first optical signal. The current signal output terminal of the optical signal receiver is used to convert the first optical signal into a current signal, and the current signal output terminal of the optical signal receiver is electrically connected to the input terminal of the processor.
[0011] In one possible implementation, the optical signal communicator has an optical signal transmitter, the electrical signal input terminal of which is electrically connected to the output terminal of the processor, and the optical signal transmitter is used to transmit a first optical signal in the form of an optical signal.

A fourth interface is provided on the other side of the Jacquard comb, and the optical signal transmitter is disposed in the fourth interface.
[0013] In one possible implementation, at least one second power interface is provided on the other side of the Jacquard comb. The second power interface of the first Jacquard comb is electrically connected to the first power interface of the second Jacquard comb, so that the two Jacquard combs are arranged together. The optical signal receiver of the first Jacquard comb is connected to the optical signal transmitter of the main controller. The Jacquard comb receives process data sent by the external main controller through the optical signal receiver in the form of a first optical signal transmission. The main controller is used to send process data to the corresponding Jacquard comb so that the Jacquard comb completes the jacquard action after being powered on. The optical signal transmitter of the first Jacquard comb is connected to the optical signal receiver of the second Jacquard comb.
[0014] In one possible implementation, the second power interface of the second Jacquard comb is electrically connected to the first power interface of the Nth Jacquard comb, thereby arranging the N Jacquard combs together, and connecting the optical signal transmitter of the second Jacquard comb to the optical signal receiver of the Nth Jacquard comb.
[0015] In one possible implementation, the electrical signal input terminal of the optical signal transmitter is used to convert the current signal output by the processor into a first optical signal.
[0016] In one possible implementation, the optical signal receiver is a photodiode, and the optical signal transmitter is a light-emitting diode.
[0017] In one possible implementation, the first optical signal is a communication address setting signal or an injection signal.
[0018] In one possible implementation, the first optical signal is configured as process data for driving the Jacquard comb.
[0019] Secondly, this disclosure provides a warp knitting machine, including at least one Jacquard device, wherein the Jacquard device is the Jacquard device described above.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] This utility model has a simple structure and strong practicality. By setting up an optical signal communicator to replace the communication bus, on the one hand, the optical signal communicator completes the process data transmission between Jacquard combs. The first optical signal is received by the optical signal receiver, so it is not affected by the electromagnetic interference of the power line and has stronger anti-interference ability, effectively improving the stability of the Jacquard comb when receiving process data signals. On the other hand, it reduces the number of conductive interfaces on the Jacquard comb, achieving two benefits at once. Attached Figure Description
