As shown in fig. 5, each of the yarn feeding wheel body 301 and the yarn discharging wheel body 401 has a plurality of yarn threading grooves x, the yarn threading groove x of each yarn feeding wheel body 301 is opposite to the yarn threading groove x of the yarn discharging wheel body 401 on the same layer, the yarn threading groove x of each yarn feeding wheel body 301 and the corresponding yarn threading groove x of the yarn discharging wheel body 401 are used for allowing an independent braided tube to pass through, so that when a large number of braided tubes are conveyed, the braided tubes are independently separated, and at the same time, the braided tubes passing through the grooves are limited from moving transversely, so as to prevent the braided tubes from being stacked and wound by transverse displacement, and the yarn threading grooves x of each layer of yarn feeding wheel body 301 are staggered with the yarn threading grooves x of the different layers of yarn feeding wheel body 301 and the yarn threading grooves x of the different layers of yarn discharging wheel body 401, when the braided tubes of different layers reach the yarn pressing mechanism 2, the integrated braided tubes of each layer are in a single layer during the pressing process of the yarn pressing mechanism 2, in this embodiment, a plurality of braided tubes in each layer can be still maintained in a staggered state after the integration is completed, and stacking and winding cannot be caused.

As shown in fig. 6 to 8, the multi-hole spinneret mechanism 5 further includes a positioning member 503, the positioning member 503 is disposed on the mounting groove 501a transversely with respect to the spinneret plate 502, so as to clamp the spinneret plate 502 in the mounting groove 501a, effectively position the spinneret plate 502, and prevent the spinneret plate 502 from shifting, and the positioning member 503 is detachably connected to the seat body 501 at the periphery of the mounting groove 501a, specifically, the positioning member 503 can be connected to the seat body 501 by a threaded fastener, a snap connection, or other ways, and in this embodiment, the positioning member is connected to the seat body 501 by a threaded connection, so that an operator can add or remove the spinneret plate 502 quickly.

As shown in fig. 6 to 8, the seat body 501 is provided with a hot water flow channel 501c disposed around the mounting groove 501a, in this embodiment, the hot water flow channel 501c is used for communicating with an external hot water source, and after the valve is opened, hot water can enter the hot water flow channel 501c through a pipeline.

As shown in fig. 9, the front frame 602 and the rear frame 603 each include a main body y and a detachable supporting portion z connected to two sides of the main body y, the main body y is detachably connected to the connecting plate 601, the shaft 604 is detachably mounted between the two supporting portions z, in this embodiment, the end of the shaft 604 can be exposed by detaching the supporting portion z, so that the yarn feeding wheel set 3/the yarn discharging wheel set 4 can be easily sleeved on the shaft 604 or taken down from the shaft 604, and therefore the number of the yarn feeding wheel set 3/the yarn discharging wheel set 4 can be flexibly adjusted according to different specifications of required produced cellophane yarns or other actual production requirements.

As shown in fig. 10 and 11, the lifting mechanism 7 further includes: the bearing plate 704 is arranged on one side of the power mechanism 8 and is connected with the rack 1, a slide rail 705 is arranged on the bearing plate 704, the slide rail 705 is configured to be at least one and is parallel to the piston rod 801, a slide block 706 is connected to the slide rail 705 in a sliding manner, and the slide block 706 is connected with the bearing table 702 at the same time.

As shown in fig. 10, the carrier plate 704 is provided with a deviation preventing member 707 opposite to the transmission rod 701, the transmission rod 701 passes through the deviation preventing member 707, and preferably, the deviation preventing member 707 is disposed at an upper position of the carrier plate 704, in this embodiment, the deviation preventing member 707 plays a role in centering and guiding the transmission rod 701, so that the transmission rod 701 can always keep moving in the up-and-down direction.

With reference to fig. 1 to 11, the specific principle of the spinning nozzle mechanism of the present invention is that, when mounting, the spinning nozzle bodies 301 and the spinning nozzle bodies 401 included in the spinning nozzle inlet wheel set 3 and the spinning nozzle outlet wheel set 4 of each layer are respectively mounted on the corresponding shaft rods 604, and after mounting, the spinning nozzle bodies 401 and the spinning grooves x on the spinning nozzle bodies 301 of the same layer are ensured to be opposite to each other, the spinning grooves x on the spinning nozzle bodies 301 of different layers are staggered from the spinning grooves x on the spinning nozzle bodies 401, so that the braided tubes passing therethrough are not stacked and wound, the spinning nozzles 502 with the same number as the spinning nozzle bodies 301 in the corresponding spinning nozzle sets 4 are placed in the mounting grooves 501a of the base body 501, the positions of the spinning nozzles 502 are adjusted to keep the spinning nozzle holes 502a on the spinning nozzle nozzles 502 opposite to the spinning nozzle bodies 401, and after the spinning nozzle bodies 502 are mounted, the positioning members 503 are horizontally placed above the receiving grooves 501a, thereby clamping the spinneret plate 502 between the spinneret plate and the receiving groove 501a, avoiding displacement of the spinneret plate 502, layering the braided tubes to be solidified, controlling one end of the braided tubes to sequentially pass through the corresponding layers of the spinning inlet pulley body 301, the spinning groove x on the spinning outlet pulley body 401 and the spinning nozzle 502a on the spinneret plate 502, keeping the braided tubes independent and free from winding and stacking, supplying air to the cylinder body of the power mechanism 8 during spinning operation, moving the piston rod 801 outwards, driving the transmission rod 701 to synchronously move, simultaneously moving the bearing platform 702 connected with the transmission rod 701, driving the positioning framework 6 to synchronously move by the push rod 703 connected with the bearing platform 702, thereby realizing lifting of the spinning inlet pulley group 3, the spinning outlet pulley group 4 and the multi-hole spinning mechanism 5, wherein the moving direction of the bearing platform 702 is consistent with the trend of the slide rail 705, and driving the slide block 706 to synchronously move along the slide rail 705 during the moving process, the slide rail 705 can be used for centering and guiding, and the anti-deflection member 707 in the bearing plate 704 also can be used for centering and guiding the transmission rod 701, so that the transmission rod 701 can always keep moving in an up-and-down direction.

The foregoing embodiments and description have been presented only to illustrate the principles and preferred embodiments of the invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention as hereinafter claimed.
