[0016] Working process of the present invention:

[0017] During the operation of the disk head unwinding device of the warp knitting machine for comfortable and durable flame-retardant warp knitted fabrics of the present invention, the rotating shaft 22 is inserted into the disk head 25 with the yarn wound thereon, and then the two fixing mechanisms 26 are respectively inserted from the two ends of the rotating shaft 22 when the latch head of the indexing pin 262 is retracted, until the fixing mechanism 26 is close to the disk head 25, and then the latch head of the indexing pin 262 is inserted into the corresponding slot 27, and then the adjusting disk 263 is rotated to move backward, and the adjusting disk 263 drives the sliding body 265 to move backward through the cap body 267, and the sliding body 265 drives the first toothed disk 268 to move backward, and the first toothed disk 268 is meshed and connected with the corresponding second toothed disk 28 to fix the disk head 25, and then the rotating shaft 22 with the disk head 25 fixed thereon is hoisted by the hoisting equipment and placed between the upper and lower bearings 24, and it is ensured that the bearings 24 are located The annular groove 29 is then used to push the connecting sleeve 217 forward so that the connecting sleeve 217 is sleeved on the plug-in portion 210, and the fastening bolt 219 is tightened. When the through hole of the connecting sleeve 217 cannot completely overlap with the plug-in portion 210, the connecting sleeve 217 cannot move forward at this time, and the rotating shaft 22 needs to be rotated for adjustment until the through hole of the connecting sleeve 217 completely overlaps with the plug-in portion 210, and then the second swing arm 203 is rotated to press the roller 206 on the yarn wound on the disk head 25, and then the servo motor 211 is started through the controller, and the servo motor 211 drives the driving gear 213 to rotate through the reducer 212, and the driving gear 213 drives the driving shaft 216 to rotate through the driven gear 214, and the driving shaft 216 drives the rotating shaft 22 to rotate through the connecting sleeve 217 for unwinding; since the yarn wound on the disk head 25 will become less during use, such as Figure 3The roller 206 shown will naturally move downward as the yarn becomes less, and the roller 206 drives the shaft 201 to rotate through the second swing arm 203, and the shaft 201 drives the first swing arm 202 to rotate. When the first swing arm 202 contacts the contact switch 205 (that is, when the disc head 25 needs to be replaced), the contact switch 205 sends a signal to the controller 1, and the controller 1 controls the whole machine to stop and starts the alarm 2011 to alarm.

[0018] When the disk head 25 needs to be replaced, loosen the fastening bolt 219 and pull the connecting sleeve 217 backward until the connecting sleeve 217 is completely removed from the plug-in portion 210, and then use a lifting device to transfer the movable shaft 22 from the bearing 24 to the ground, and then pull the handle of the indexing pin 262 to remove the pin head from the slot 27, and then the fixing mechanism 26 can be removed from the shaft 22, and then the shaft 22 can be pulled out to insert the disk head 25 wound with yarn.

[0019] When two or more pan heads 25 are fixed on the rotating shaft 22 , the head and tail of two adjacent pan heads 25 can be meshed and connected together through the second gear plate 28 , thereby improving the fixing effect of the two adjacent pan heads 25 .

[0020] Compared with the prior art, the invention has a good fixing effect, ensures product quality, and can automatically stop and alarm.

[0021] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
