[0029] like Figure 6 and Figure 7 As shown, in one embodiment of the present invention, two swing cylinders 24 are installed on the lower surface of the lower plate 1, the first swing cylinder 24 is on the right side, and the second swing cylinder 24 is on the left side. The upper ends of the first swing cylinder 24 and the second swing cylinder 24 both penetrate the lower plate 1 and extend into the gear chamber. The upper ends of the first swing cylinder 24 and the second swing cylinder 24 are respectively fixedly connected with the first transmission shaft 25 and the second transmission shaft 25, and one end of the first connecting rod 26 and one end of the second connecting rod 26 are respectively fixedly connected to the first transmission shaft 25 and the second transmission shaft 25, and the other end of the first connecting rod 26 and the other end of the second connecting rod 26 are respectively connected to the first pin 23 and the second pin 23, and the upper end of the first swing cylinder 24 and the output end of the second swing cylinder 24 are respectively in the first arc hole 22 and the second arc hole 2 2 arc center, and then the first transmission shaft 25 and the second transmission shaft 25 are also located at the center of the arc line of the first arc hole 22 and the arc line of the second arc hole 22 respectively.

[0030] When weaving round wire, the first travel switch 21, the second travel switch 21, the third travel switch 21 and the fourth travel switch 21 are powered off, and the rotation of the variable track block 16 is not triggered. At this time, the variable track block 16 is in a state where the notch of the first linear track groove 17 is tangent to the notch of the common track 3. The common track 3, the first linear track groove 17 on the variable track block 16 and the second linear track groove 20 on the fixed track block 19 form a closed annular track, and the spindle reciprocates on the annular track. In the initial state, the spindle is stuck in the second groove 8, and two spindles are arranged every two second grooves 8. The specific arrangement is as follows: Figure 2As shown. Then, during the process of weaving the round wire, the electric control box issues a command, and the main motor 11 and the secondary motor 14 start working, thereby starting to drive the first dial 5 and the second dial 7 to start moving. Taking the spindle on the number one second dial 7 as an example, when the spindle on the number one second dial 7 contacts the second groove 8 on the number two second dial 7, the spindle on the number one second dial 7 will be transferred to the second groove 8 on the number two second dial 7, and then the spindle will be transferred to the number three second dial 7, the number four second dial 7, the number five second dial 7, the number six second dial 7, the number seven second dial 7 and the first dial 5 in turn, until it is transferred to the number one second dial 7 again, and the above actions are repeated. The steering of the first dial 5 and the seven second dials 7 and the movement trajectory of the spindle are shown as follows. Fig.12 The specific working principle is the existing technology and will not be described in detail here.

[0031] When the braided fabric needs to be changed from round wire to flat wire, the electric control box sends out a command, and the first stroke switch 21, the second stroke switch 21, the third stroke switch 21 and the fourth stroke switch 21 are energized, and the special spindle will collide with the first stroke switch 21. The signal generated by the first stroke switch 21 serves as the start signal for the variable track block 16 to change the track, and the track is switched from round wire braiding to flat wire braiding. The diameter of the spindle seat upper disk of the special spindle is 1 / 4 larger than the diameter of the spindle seat upper disk of the ordinary spindle to ensure that only the spindle seat upper disk on the special spindle can trigger each stroke switch 21, while the ordinary spindle cannot be triggered. Since the positions of the special spindles and the ordinary spindles are constantly changing, the positional relationship between the special spindles and the ordinary spindles mentioned above is only the working principle described for the positions of the special spindles and the ordinary spindles in the attached drawings.

[0032] When weaving flat wire, the special spindle is the starting spindle, and other ordinary spindles follow the special spindle to move along the same trajectory. The special spindle enters the first dial 5 from the second dial 7 No. 7 along the first straight track groove 17 on the second variable track block 16. During this process, the upper plate of the spindle seat on the special spindle first collides with the first stroke switch 21, and the first stroke switch 21 sends a signal to the electric control box. After processing, the electric control box sends an air supply command to the first solenoid valve 27. The compressed gas generated by the first air compressor passes through the first air supply pipe, the first solenoid valve 27, and the first air supply pipe into the first swing cylinder 24, and then the first swing cylinder 24 is actuated, and the first swing cylinder 24 drives the first transmission shaft 25 to rotate, and the rotation of the first transmission shaft 25 drives the first connecting rod 26 to rotate, and the rotation of the first connecting rod 26 drives The first pin 23 slides inside the first arc hole 22, and the first pin 23 drives the first variable track block 16 to rotate. The first variable track block 16 changes from the notch of the first linear track groove 17 being tangent to the notch of the common track 3 to the notch of the arc track groove 18 being tangent to the notch of the common track 3; then the special spindle will move along the arc track groove 18 on the first variable track block 16 and then be transferred to the first dial 5 again. During the rotation, the special spindle will collide with the third stroke switch 21, and the third stroke switch 21 sends a signal to the electric control box. After processing, the electric control box does not send an air supply command to the first solenoid valve 27, and the first swing cylinder 24 does not move; the special spindle passes through the second The first linear track groove 17 on the variable track block moves to the second dial 7 No. 7, and then passes through the second dial 7 No. 6, the second dial 7 No. 5, the second dial 7 No. 4, the second dial 7 No. 3, and the second dial 7 No. 2 in sequence. When the special spindle passes through the second dial 7 No. 2, the special spindle hits the second stroke switch 21, and the second stroke switch 21 sends a signal to the electric control box. After processing, the electric control box sends an air supply command to the first solenoid valve 27, and the first swing cylinder 24 is actuated to drive the first variable track block 16 to rotate. The first variable track block 16 changes from the notch of the circular arc track groove 18 being tangent to the notch of the common track 3 to the notch of the first linear track groove 17 being tangent to the notch of the common track 3. The special spindle will then move from the second dial 7 No. 2 to the second dial 7 No. 1, and then from the second dial 7 No. 1 through the first linear track groove 17 on the first variable track block to the first dial 5. During the rotation of the special spindle on the first dial 5, the special spindle collides with the third stroke switch 21, and the third stroke switch 21 sends a signal to the electric control box. After processing, the electric control box sends an air supply command to the second solenoid valve 27, and the second swing cylinder 24 is actuated to drive the second variable track block 16 to rotate. The second variable track block 16 changes from the notch of the first linear track groove 17 being tangent to the notch of the common track 3 to the notch of the arc track groove 18 being tangent to the notch of the common track 3.Then the special spindle moves along the circular arc track groove 18 on the second variable track block 16, and after going around the first dial 5 for a full circle, it enters the No. 1 second dial 7 along the first straight track groove 17 on the first variable track block 16 again, and then passes through the No. 2 second dial 7, the No. 3 second dial 7, the No. 4 second dial 7, the No. 5 second dial 7, and the No. 6 second dial 7 in sequence. When the special spindle passes through the No. 6 second dial 7, the special spindle collides with the fourth stroke switch 21, and the fourth stroke switch 21 sends a signal to the electric control box. After processing, the electric control box sends an air supply command to the second solenoid valve 27, and the second swing cylinder 24 is actuated to drive the second variable track block 16 to rotate. The second variable track block 16 changes from the notch of the circular arc track groove 18 being tangent to the notch of the common track 3 to the notch of the first straight track groove 17 being tangent to the notch of the common track 3; then, the special spindle moves to the initial position and continues to reciprocate along the above trajectory. The first variable track block and the second variable track block 16 are switched back and forth according to the above switching control principle to realize flat wire weaving. ;

[0033] When the braided fabric needs to be changed from flat wire to round wire, the signal generated by the special spindle colliding with the first stroke switch 21 is used as a signal to cut off the power of the first stroke switch 21, the second stroke switch 21, the third stroke switch 21 and the fourth stroke switch 21. After the electric control box controls the stroke switch 21 to cut off the power, the first variable track block 16 and the second variable track block 16 stop the track changing action, and the track at this time is exactly the round wire braiding track, so the switching from flat wire braiding to round wire braiding can be realized.

[0034] In this way, the three weaving modes of round wire weaving, flat wire weaving and round-flat alternating weaving can be switched without stopping.

[0035] In the above working principle, the transmission process of the spindles on the first dial 5 and the second dial 7 and the process of the spindles weaving round fabrics and flat fabrics are all existing technologies and will not be described in detail here.
