An external thread 4033 is arranged at the other end of the yarn guide installation sleeve 4032, and a plurality of holes for installing the yarn guide ring installation sleeve 4032 are opened on the yarn guide bottom plate 4034, and each yarn guide ring installation sleeve 4032 passes through the hole and is screwed with the external thread 4033 through a nut, so as to lock the yarn ring installation sleeve on the yarn guide bottom plate 4034.

[0052] like Figure 4 As shown, the yarn clamping device 402 is fixed to the yarn clamping bottom plate 4025, and at least one positioning block 4027 is arranged on the bottom surface of the yarn clamping bottom plate 4025 for fixing on the second slide plate 305 of the servo device. Preferably, in this embodiment, the first positioning blocks 4027 are a pair, and the spacing between adjacent first positioning blocks 4027 can be inserted into the second slide plate 305.

Since the spring 4018 has an elastic force, the lower tension plate 4019 can float up and down under the elastic action, thereby ensuring that the yarn is smoothly drawn out and the yarn is not broken.

[0055] The at least one yarn holding device is installed at the movable end of the servo device 3 so as to be used for the yarn holding device to move in multiple directions.

[0065] The specific working process of the present invention is as follows:

[0066] Yarn racking action:

[0067] The worker moves the yarn rack device connected to the servo device 3 as a whole to the spindle car through the moving device 1. Figure 2As shown, release the fixation of the positioning 4010 and the bracket 4015, move the upper mounting plate 4016 to the stop of the opening 40151, and place the upper mounting plate 4016 on the stop. The worker takes the yarn head off from the spindle marked with the number on the spindle car, circles the yarn head around the yarn guide ring 4031 and passes it out, then passes it through the open slot on the lower tension frame 4012, and finally passes it between the two magnetic sheets 4022. The adjacent connected magnetic sheets 4022 are positive and negative magnetic sheets, which are bonded to the adhesive strip 4028 after passing through. The erection time of each yarn is 1 second, and each spindle is erected using the above method. After all the erection is completed, the upper mounting plate 4016 is as shown in FIG. Figure 2 The lower mounting plate 4016 is fixed in position by the positioning plate 4010, and the spring 4018 is extended by gravity to make the lower tension plate 4019 pass through the lower tension frame 4012, and the yarn end passes through the gap between the lower tension plate 4019 and the lower tension frame 4012.

[0068] Yarn moving action:

[0069] The worker moves the yarn holding device, the servo device 3 and the mobile device 1 as a whole to the vicinity of the yarn pressing and splicing device 5, and activates the electromagnetic suction cup 202 to make it have magnetic adsorption force to firmly adsorb the magnetic plate 201, so that the yarn pressing and splicing device 5 and the mobile device 1 cannot be separated.

[0070] Then as Figure 6 As shown, the worker manually controls the servo device to move, and the second slide block 303 moves linearly along the second slide 302, so that the first slide block 304 is close to the yarn pressing and splicing device 5. In this process, the first slide block 304 is locked with the second slide block 305 by the locking rod 306. Figure 1 , Figure 2 and Figure 6 As shown, when the first slide plate 304 slides to the limit position, the locking rod 306 is unlocked, and the second slide plate 305 is moved, so that the yarn clamping device 402 connected to the second slide plate 305 is moved as a whole to the frame 503 (as shown in FIG. Fig. 9 As shown), the worker removes the yarn clamping device 402, and then embeds the first positioning block 4027 at the bottom of the yarn clamping base plate 4025 into the opening of the second positioning block 524, and the yarn clamping device 402 is clamped in the frame 503 by the elastic top block 5241.

[0071] At this time, the worker closes the electromagnetic suction cup 202 and pushes the moving device 1 together with the servo device 3 in reverse as a whole, so that all the yarns are horizontally parallel and cross over the top of the pressing and splicing device 5 .

[0072] Yarn pressing and pushing action:

[0073] Push yarn: Figures 9 to 11As shown, when the yarn crosses over the splicer 508 in the pressure splicing device 5, due to the large spacing between two adjacent strands of yarn, the two strands of yarn may not enter the splicing head of the splicer 508, as shown in FIG. Figures 7 to 9 As shown, the worker inputs a control command in the PLC console 502, the first stepper motor 519 receives the command and controls the first screw rod 504 to rotate, and the first screw rod nut 505 moves axially along the first screw rod 504 to drive the movable base 506 to move between the two yarns, as shown in FIG. Fig.12 As shown, during this process, the thread pushing rod 528 contacts one of the yarns and pushes one yarn toward the other yarn, so that the two yarns are closely approached and located above the splicing head of the splicer 508.

[0074] Yarn pressing: In order to meet the requirements of twisting two strands of yarn in the splicer 508, such as Figures 8 to 11 As shown, the PLC console 502 issues a command, the cylinder 512 is started, and its piston drives the movable plate 514 to move downward relative to the vertical plate 525. Since the left and right sides of the movable plate 514 are respectively fixed with the wire pressing plate 511, the wire pressing plate 511 also moves downward. During the downward process, the wire pressing plate 511 contacts two yarns and presses them down into the splicing head of the splicer 508.

[0075] Color: Fig.12 As shown, during the downward movement of the wire pressing plate 511, since one side of the movable plate 514 is fixedly connected to the pressing block mounting plate 529, the pressing block 530 also moves downward along with the movable plate 514. After moving downward, the pressing block 530 contacts the yarn and presses it into the ink cartridge 532 for coloring, thereby realizing the segmented color marking of each section of the yarn, so that the segmented color marking can be seen on the final entire continuous cylindrical braided belt to correspond to the spindles.

[0076] Twisting: Figures 8 to 11 As shown, after being in place, the second stepper motor 520 starts working, and completes the rotational twisting (knotting) in sequence through the mechanical transmission of the flange coupling 518, the bearing 517, and the first elastic coupling 516. In this process, the two strands of yarn are mainly untwisted and cut off in the twisting chamber. After the twisting is completed, the yarn pressing action is reset. At the same time, the PLC console 502 controls the first screw nut 505 in the servo slide to advance one station to prepare for the next twisting. After the yarn twisting is completed, the yarn head passes through the yarn holder 510 and then enters the dyeing test weaving machine.

[0077] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
