Description
Technical Field
The invention relates to the field of textile machines, in particular to a needle bed and a textile machine using the needle bed.
Background
The invention includes, but is not limited to, the application in the field of warp knitting machines, and the following description is given by taking a warp knitting machine as an example.
Knitting is carried out by simultaneously looping one or more sets of parallel aligned yarns on all the needles of a warp-feed machine, known as warp knitting, which is called warp knitting fabric, and machines for carrying out this knitting, known as warp knitting machines.
The warp knitting machine mainly comprises a knitting mechanism, a guide bar shogging mechanism, a let-off mechanism, a drawing and coiling mechanism and a transmission mechanism.
The knitting mechanism includes a needle bed, a guide bar, a sinker bed and a presser plate, typically driven by a cam or eccentric link. Cams are often used in warp knitting machines with relatively low speeds and relatively complex motion laws of the knitting elements. The eccentric connecting rod is stable in transmission, simple and convenient to process and low in abrasion and noise during high-speed operation, so that the eccentric connecting rod is widely applied to a high-speed warp knitting machine.
The guide bar transverse moving mechanism enables the guide bar to transversely move according to the requirements of the knitted fabric texture in the looping process, and the warp yarns are padded on the needles so as to weave the knitted fabric with a certain texture structure. There are generally both platen and cam types. The pattern plate type mechanism is connected in series into a pattern plate chain according to the requirements of the knitted fabric tissue through pattern plates with certain shapes and sizes, so that the guide bar is transversely moved, the pattern plate type mechanism is suitable for weaving the tissue with more complicated patterns, and the pattern conversion is more convenient. The cam in the cam type mechanism is designed according to the guide bar shogging rule required by the knitted fabric tissue, so that the transmission is stable, and the cam type mechanism can adapt to higher knitting speed.
The warp feeding mechanism is used for releasing the warp on the warp beam and feeding the warp into the weaving area. There are two types, passive and active. The warp beam in the passive mechanism is pulled by warp tension to send out warp, a special warp beam transmission device is not needed, and the passive mechanism is suitable for warp knitting machines with low machine speed and complex let-off rule. The positive let-off mechanism uses a special transmission device to make the warp beam rotate to let off warp, and has the difference of tension induction type and linear velocity induction type. The tension sensing mechanism senses the tension of the warp yarn through the tension rod to control the rotating speed of the warp beam. The linear velocity induction type mechanism controls the rotating speed of the warp beam by inducing the motion speed of the warp through the speed measuring device. Such a mechanism feeds out warp yarns at a predetermined linear speed, and can stably operate under a high-speed operation condition, and thus is widely used in a high-speed warp knitting machine.
The function of the drawing and winding mechanism is to draw the fabric from the weaving area at a preset speed and wind the fabric into a cloth roll.
The personalized pursuit of people for the patterns of the cloth is higher and higher. For example, many people now prefer raised patterns and wrinkled effects on cloth. As most of the prior common textile equipment technology uses the eccentric cam to drive the needle bed connecting rod to push the needle bed to move along with the traditional technology, the prior requirement has certain limitation.

While RS-232 communication interfaces typically come in the form of either 9 pins (DB-9) or 25 pins (DB-25), two sets of RS-232 interfaces, referred to as COM1 and COM2, are typically available on personal computers. The RS232 communication interface supports the EIA-RS-232C standard, where EIA (electronic Industry association) stands for american electronics Industry association, RS (recommended standard) stands for recommended standard, 232 is an identification number, C stands for the latest modification of RS232 (1969), preceded by RS232B, RS232A, which specify the connecting cables and mechanical, electrical characteristics, signal functions and transmission processes, and the common physical standards also include EIARS-422A, EIA RS-423A, EIARS-485. The RS485 communication interface is a serial-port-based communication interface, is consistent with the data receiving and transmitting operation of the RS232 communication interface, and uses a bottom-layer driver of WinCE.

Electrical characteristics of RS 485: a logic "0" is represented by a voltage difference between the two wires of + (2-6) V; a logical "1" is represented by a voltage difference between the two wires of- (2-6) V. The interface signal level is lower than RS-232-C, the chip of the interface circuit is not easy to damage, and the level is compatible with TTL level and can be conveniently connected with TTL circuit.
The I/O communication interface is a link for information exchange between the host and the controlled object, and the host can exchange data with external equipment through the I/O interface; the I/O communication interface can support General Purpose Input/Output (GPIO), Pulse Width Modulation (PWM), I2C bus (Inter-Integrated Circuit, I2C bus), Universal Asynchronous Receiver/Transmitter (UART), wherein GPIO is a simplest protocol and can only read and write high/low level signals; PWM can only simply send square wave signals outwards; I2C and UART are serial interface protocols, can continuously read and write a large amount of data and are used for more complex equipment.
The CAN bus communication interface integrates the functions of a physical layer and a data link layer of a CAN protocol, and CAN complete framing processing of communication data, including bit filling, data block encoding, cyclic redundancy check, priority discrimination and other work. Compared with a general communication bus, the CAN bus has outstanding reliability, instantaneity and flexibility, and typical application protocols of the CAN bus include SAE J1939/ISO11783, CANopen, CANaerospace, DeviceNet, NMEA 2000 and the like.
