Problems solved by technology
[0004] However, the existing stitch control system has the following problems to be solved urgently: the maximum output speed of the existing stepper motor for stitch control is only 600RPM, and the positioning accuracy is 1.8°; Only rough positioning can be achieved, and the positioning accuracy is 15°
The current servo motor with a photoelectric encoder has a maximum output speed of 3000RPM and a positioning accuracy of 0.09°, but the motor is large and expensive; in addition, the installation of the external photoelectric encoder is complicated, and the sensor needs to be added to the controller for receiving processing The conversion circuit increases the complexity of the equipment installation process

[0042] Such as figure 1 As shown, the first embodiment of the stitch control system 1 of the textile equipment of the present invention comprises:
[0043] Servo driver 1, servo motor 3 and magnetic encoder 2;
[0044] Wherein, the servo driver 1 is connected with the magnetic encoder 2, and is used to drive the servo motor 3 to control the stitch of the textile equipment; Rotate to obtain a sensing signal, and send the sensing signal to the servo driver 2 .
[0045] Before the equipment works, it is necessary to fix the magnetic steel at the tail of the motor. The magnetic encoder chip needs to be aligned with the magnetic steel, and the distance between the magnetic steel and the magnetic encoder chip is kept between 0.8MM and 1.5MM before it can be used.
[0046] When working, on the basis of the open-loop controlled servo motor 3, the magnetic encoder 2 receives the periodic electrical signal of the relative position and speed signal, and then converts the electrical sig...

The invention discloses textile equipment and a stitch control system thereof. The stitch control system of the textile equipment comprises a servo driver, a servo motor and a magnetic encoder. The magnetic encoder and the servo motor cooperate the magnetic encoder is arranged opposite to an output shaft and then senses rotation of the output shaft of the servo motor to obtain sensing signals, the magnetic encoder is connected with the servo driver to output the sensing signals to the servo driver, and accordingly the servo motor is driven to rotate. By means of the stitch control system, precision control over stitches is achieved; space resources needed for installation of the equipment and production cost are reduced; the installation process of the equipment is simplified.
Description
technical field [0001] The invention relates to the technical field of textiles, in particular to textile equipment and a stitch control system thereof. Background technique [0002] Textile equipment such as knitting machines are equipment used to weave fabrics, which mainly include power circuits, operation boxes, main control circuit boards, machine heads, motors, drivers, and machine tools for installing the above components. At present, the knitting control of the knitting machine depends on the back and forth movement of the machine head on the machine tool, and relies on the triangular structure on the machine head to push the needles to complete the knitting operation. In the cam structure, a stitch cam is installed to control the knitting density, and the stitch cam is controlled by a stitch motor through a transmission device. [0003] At present, stepping motors or brushless motors are commonly used in the current Stüme motors, which are externally connected with...
