Controller for yarn changer

[0025] The present invention will be further described below in conjunction with the embodiments, and the purpose is only to better understand the content of the present invention. Therefore, the examples cited do not limit the protection scope of the present invention.

[0026] See figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Including the controller frame 1 installed on the outer panel 12 of the main body of the line changer, and also includes a transmission rod 4, a digital circuit 11, and a driving mechanism for driving the transmission rod 4 to move linearly. The driving mechanism includes a driving motor and a reducer 2 , The transmission gear 3, the drive motor and the reducer 2, and the digital circuit 11 are respectively fixedly installed on the controller skeleton 1 through bolts 6. The transmission gear 3 and the transmission rod 4 are respectively installed on the controller skeleton 1 through the pin 5, and the transmission rod 4 is provided with a long hole 13 that is matched with the pin shaft 5 and can slide linearly on the pin shaft 5 to achieve different position requirements for subsequent control. The shaft end of the power output shaft of the drive motor and the reducer 2 is provided with a transmission The pinion gear 7 meshed with the gear 3, the main yarn cutter of the yarn cutting device 10 on the outer plate 12 of the thread changer body is mounted on the outer plate 12 of the thread changer body through a pin, and the main yarn cutter is provided with a concave surface , The upper end of the transmission rod 4 is provided with a linear rack 14 which is matched with the transmission gear 3, and the lower end of the transmission rod 4 is provided with a convex foot 15 which is matched with the concave surface of the main cutter of the yarn clamping device 10, the transmission rod 4 When performing linear motion, the protruding feet 15 on it form a pressing force on the concave surface of the main cutting knife, so that the yarn clamping and cutting device 10 swings around the pin 5, and the drive motor is electrically connected to the reducer 2 and the digital circuit 11. The circuit 11 is used to control the actions of the drive motor and the reducer 2 to meet subsequent control requirements.

[0027] The controller skeleton 1 is provided with multiple groups of driving mechanisms, and on the controller skeleton 1 corresponding to the transmission gears 3 of each group of driving mechanisms, a plurality of transmission rods 4 are provided. The transmission rods 4 are connected with the pressure on the outer plate 12 of the main body of the wire changer. The main yarn cutters of the yarn clamping device 10 correspond one to one.

[0028] The working principle is: the digital circuit 11 controls the drive motors of the multiple drive mechanisms to work with the reducer 2, and the pinion 7 rotates to drive the corresponding transmission gear 3 to rotate, and the transmission gear 3 passes through the linear teeth on the corresponding transmission rod 4. The strip 14 cooperates to make the transmission rod 4 move linearly. When the transmission rod 4 moves linearly, the protruding feet 15 provided on the transmission rod 4 form a pressing force against the concave surface of the main yarn cutter of the corresponding yarn clamping and cutting device 10 to make the clamping The yarn cutting device 10 arrives at the yarn participating in the knitting, and the yarn participating in the knitting is selected. At this time, the yarn clamping device 10 is in the yarn selection state, and then the protruding foot 15 on the transmission rod 4 continues to press and clamp the yarn The concave surface on the main cutting knife of the yarn cutting device 10 makes the yarn clamping and cutting device 10 swing around the pin 5 and rotate the yarn participating in the knitting to the knitting area. At this time, the yarn clamping and cutting device 10 is in the yarn-drawing state. So far, the yarn selection and threading actions are completed.

[0029] This device does not need to cooperate with the cam of the knitting machine, eliminates external drive, and relies on the digital circuit 11 to control the drive mechanism to drive the transmission rod 4 to drive the yarn clamping and cutting device to complete the yarn selection and threading actions, and realize the yarn selection and threading of the thread changer. The independent control and the expected function of the wire changer, the impact and vibration are small, the applicability is strong, the work is stable, and the structure is simple, which is beneficial to improve the stability of the knitting machine production.
