[0027] like Figure 1 , Figure 2 and Figure 3 and Figure 4 As shown, in one embodiment: the weaving assembly includes a needle plate 4 installed at the top of the casing 1 and connected to the rotating frame 7, a thread supply frame 2 installed at the top of the needle plate 4, and a reel 3 installed inside the thread supply frame 2, the guide assembly includes a second guide roller 12 fixed to one side of the inside of the frame 5, a first guide roller 10 rotatably connected to the top of the inside of the frame 5, and a fourth telescopic cylinder 15 installed on both sides of the inside of the frame 5 and connected to the first guide roller 10 at the telescopic end, one side of the casing 1 is rotatably connected to a hatch 16, and the bottom end of the hatch 16 is rotatably connected to an electric push rod 17 rotatably connected to the casing 1.

[0028] Specifically, when the present textile circular knitting machine is in use: the device is placed in a predetermined position, the yarn is passed through the reel 3 and introduced into the needle hole inside the needle disk 4, after the device is started, the yarn is fed into the needle disk 4 via the reel 3, and is guided by the knitting needles in the needle disk 4 for weaving, and the knitted fabric will be guided by the first guide roller 10 and the second guide roller 12 and contact the winding roller 13, at this time, the second guide roller 12 maintains the appropriate tension of the fabric, the fourth telescopic cylinder 15 drives the first guide roller 10 to move and flatten the rolled fabric, and then the winding structure 9 drives the winding roller 13 to rotate to realize the winding and collection of the fabric, and at the same time the flattening structure 8 will assist in moving the fabric upward Push, and apply pressure to the cloth on the outside of the winding roller 13 to ensure tight winding. When the cloth is wound around the outside of the winding roller 13 to a preset number of turns, control the winding structure 9 to loosen the winding roller 13, and then push the winding roller 13 to be replaced to move through the roll changing structure 6, and at the same time let the new winding roller 13 move between the two sets of winding structures 9. During this process, the cutting structure 11 is responsible for cutting the cloth. After the winding roller 13 with the wound cloth accumulates to a certain amount inside the discharge rack 603, the device stops running. At this time, start the electric push rod 17 to push the hatch 16 to move, open the exit of the casing 1, and the staff can use the lifting device to move the winding roller 13 loaded with cloth out from the inside of the discharge rack 603; The double-sided tape 14 is attached to the surface of the winding roller 13 so that the double-sided tape 14 can adhere and fix the cloth to the winding roller 13. The winding rollers 13 with multiple sets of double-sided tapes 14 attached are placed in the storage slot 602, so that the winding rollers 13 roll down along the inclined surface of the storage slot 602, and the storage slot 602 stores the winding rollers 13. When the roll change operation is required, the winding structure 9 is controlled to release the winding roller 13, and the first telescopic cylinder 601 is extended to push the moving frame 607 to move, so that the moving frame 607 drives the roller frame 614 and the moving frame 614 to move. The block 615 moves, so that the roller frame 614 and the moving block 615 push the winding roller 13 out of the interior of the cover 609. Later, the moving frame 607 drives the first tooth plate 613 to contact the first gear 611. Through the meshing of the teeth, the first gear 611 drives the upper roller disc 610 to rotate through the ratchet 612. The upper roller disc 610 moves a group of winding rollers 13 to between the two groups of winding structures 9, and another group of winding rollers 13 falls into the groove at the top of the upper roller disc 610. Then the moving frame 607 pushes the push block 608 to contact the push frame 605. The push block 608 pushes the push rack 605 to flip upward and distort the reset spring 604. At the same time, the push rack 605 pushes the winding roller 13 out from between the roller frame 614 and the moving block 615, so that the winding roller 13 with the wound fabric rolls down to the inside of the discharge rack 603 for storage. The first telescopic cylinder 601 is started to contract, so that the mobile rack 607 moves backward and resets. In this process, the distorted reset spring 604 drives the push rack 605 to reset, and the first tooth plate 613 pushes the first gear 611 to rotate, and the ratchet 612 causes the first gear 612 to rotate. The wheel 611 is not easy to drive the upper roller 610 to rotate during the rotation process. When the moving frame 607 drives the moving block 615 to contact the winding roller 13, the curved surface of the winding roller 13 pushes the moving block 615 to slide downward inside the roller frame 614 and squeeze the telescopic spring 616, so that the moving block 615 passes through the double-sided tape 14, and then the winding roller 13 contacts the roller frame 614. At the same time, the telescopic spring 616 pushes the moving block 615 to move upward, so that the roller frame 614 and the moving block 615 move to the outside of the winding roller 13, so as to facilitate the next roll changing operation; When the winding roller 13 moves to between the two groups of fourth telescopic cylinders 15, the third telescopic cylinder 904 is started to extend, so that the third telescopic cylinder 904 pushes the moving plate 905 to move, and then the moving plate 905 pushes the sleeve 907 to be sleeved to the outside of the hexagonal block 908 through the plane bearing 906. At the same time, the sleeve 907 pulls the transmission shaft 909 to slide inside the transmission tube 910 to compensate for the movement of the sleeve 907, and the driving motor 903 is started to drive the transmission tube 910 to rotate, so that the transmission tube 910 drives the winding roller 13 to rotate through the transmission shaft 909, the sleeve 907 and the plane bearing 906 to wind the cloth. The guide rod 902 slides inside the mounting frame 901, so that the moving plate 905 moves stably, and the plane bearing 906 makes it difficult for the rotation of the sleeve 907 to interfere with the operation of the moving plate 905. During the roll changing process of the roll changing structure 6, the moving frame 607 drives the second tooth plate 1102 to contact the second gear 1108. As the moving frame 607 moves, the second tooth plate 1102 drives the second gear 1108 to rotate, causing the screw 1107 to rotate. Then the screw block 1106 moves downward along the thread on the surface of the screw 1107 and drives the protective shell 1105 to move downward. When the moving frame 607 moves to the maximum stroke, the pressure wheel 1110 contacts the bracket 1101 and the cloth is located between the laser cutter 1109 and the bracket 1101, and the starting step is started. The inlet motor 1112 drives the synchronous wheel 1104 to rotate, so that the synchronous wheel 1104 drives the connecting seat 1111 to move through the synchronous belt 1103, and the pressing wheel 1110 and the laser cutter 1109 move on the surface of the bracket 1101, and the cloth is cut by the moving laser cutter 1109. At the same time, the pressing wheel 1110 presses the cut of the cloth, and the cloth at the cut position is not easy to have jagged cuts due to wrinkles. When the moving frame 607 moves backward, the second tooth plate 1102 pushes the second gear 1108 to rotate in the opposite direction, so that the protective shell 1105 is reset; After the winding structure 9 fixes the new winding roller 13, the second telescopic cylinder 801 is started to extend, so that the second telescopic cylinder 801 pushes the main pressure rod 804 to move up through the lifting plate 802 and the support spring 808 and contacts the unwound fabric, so that the main pressure rod 804 pushes the unwound fabric to contact the winding roller 13, so that during the rotation of the winding roller 13, the double-sided tape 14 connects and fixes the fabric and the winding roller 13. At the same time, during the winding process, as the second telescopic cylinder 801 slowly pushes the main pressure rod 804 to move up, the main pressure rod 804 is subjected to the reaction force of the fabric and pushes the lifting frame 807 to move down and squeezes the support spring 808 to contract, and moves down. The main pressure rod 804 moves through the first connecting plate 805 to pull the second connecting plate 806 to move, and the position of the auxiliary pressure rod 803 is adjusted, so that the left and right sets of auxiliary pressure rods 803 are in close contact with the cloth and apply pressure to make the cloth tightly wound. In this process, the second telescopic cylinder 801 slowly contracts as the diameter of the cloth roll changes, adjusts the pressure of the auxiliary pressure rod 803 and the main pressure rod 804 on the cloth, and slides the sliding rod 809 inside the lifting plate 802, so that the lifting frame 807 is not easy to drive the main pressure rod 804 to shake. At the same time, the limit plate 810 limits the movement range of the sliding rod 809, and the support spring 808 is used to facilitate the main pressure rod 804 to reset after being squeezed.
