[0035] The first threaded sleeve column 3 includes a threaded column body 31 and a threaded ring 32 threadedly sleeved on the outer periphery of the threaded column body 31, the threaded ring 32 is used to compress multiple wire transfer rollers 10 sleeved on the outer periphery of the threaded column body 31, and the composition and connection method of each structure in the second threaded sleeve column 5 are the same as the composition and connection method of each structure in the first threaded sleeve column 3.

[0036] Specifically, the control panel 112 is electrically connected to the heating base 12 and the temperature sensor 113 respectively. After adding and adjusting the dye in the inner cavity of the storage groove 111, the control panel 112 can be used to control the heating base 12 to heat the dye, and the temperature sensor 113 can be used to detect the temperature of the dye in the inner cavity of the storage groove 111.

[0041] A side groove 411 is provided on the outer wall of the other side of the raised shell 41, and an outer sliding hole 412 is provided on the outer wall of one end of the side groove 411. The motor 42 includes a motor body 421 and a driving shaft 422 fixedly installed on the output end of the motor body 421, and the second threaded sleeve column 5 is fixedly installed on the driving shaft 422, and limiting sliders 4221 are respectively fixedly installed on the outer walls at both ends of the driving shaft 422.

[0042] The transmission mechanism 43 includes a connecting and driving rotating block 431 and a transmission belt 432 sleeved on the outer periphery of the connecting and driving rotating block 431. The connecting and driving rotating block 431 includes a first connecting bearing 4311 and a connecting and driving sleeve 4312 movably installed on the first connecting bearing 4311, and the first connecting bearing 4311 is sleeved on the outer periphery of the driving shaft 422. An insertion slot 4313 is provided on the middle outer wall of the other side of the connecting and driving sleeve 4312, and first slots 4314 are respectively provided on the inner walls at both ends of the inner cavity of the insertion slot 4313.

[0043] The pushing mechanism 44 includes a second connecting bearing 441 and a pushing sleeve 443 installed on the second connecting bearing 441. The second connecting bearing 441 and the pushing sleeve 443 are respectively slidably sleeved on the outer periphery of the driving shaft 422. A push rod 442 is fixedly installed on the outer wall of the second connecting bearing 441. Insertion blocks 444 are respectively fixedly installed on the outer walls at both ends of the pushing sleeve 443. A sliding through hole 4431 is provided in the middle of the pushing sleeve 443, and second slots 4432 are respectively provided on the inner walls at both ends of the inner cavity of the sliding through hole 4431, and the limiting slider 4221 is slidingly set in the second slot 4432.

[0044] The driving roller 82 includes an internal connecting sleeve 821 and a through rotating shaft 822 movably installed in the internal connecting sleeve 821, and the other side end of the through rotating shaft 822 is fixedly installed with a driving roller body 823, and the other end of the transmission belt 432 is sleeved on the through rotating shaft 822, a circular rotating groove 831 is arranged on the middle outer wall of the other side of the lower support roller 83, and one end of the support roller 6 is inserted and slidably arranged in the circular rotating groove 831, a plurality of wiring grooves 841 are arranged on the outer surface of the threading transmission belt 84, and a rubber connecting rod 842 is fixedly installed on the inner wall of the middle part of the inner cavity of the wiring groove 841, and a rubber cap 843 is fixedly installed on the outer end of the rubber connecting rod 842, and the setting of the rubber cap 843 can prevent the yarn head connected to the rubber connecting rod 842 from falling off.

[0045] Specifically, in the initial state, when the motor body 421 is started, the output end of the motor body 421 will drive the second threaded sleeve column 5 to rotate through the driving shaft 422, which can simultaneously drive the take-up roller 20 to rotate and take up the line. When a new group of yarn heads needs to bypass the anti-wear roller 7 and the support roller 6 respectively, the push rod 442 can be pushed to one side. At this time, the push rod 442 will drive the push-driven sleeve 443 to move into the inner cavity of the insertion slot 4313 through the second connecting bearing 441. At this time, the insertion block 444 will also be inserted into the first slot 4314, so that the drive shaft 422 and the connecting drive rotating block 431 can be connected. Thereby, the threading assembly 8 can be started through the motor body 421 to drive the yarn heads to bypass the anti-wear roller 7 and the support roller 6 respectively. One machine has multiple uses, which is convenient and quick to operate, and also saves the use cost and manufacturing cost.

[0046] Furthermore, when a group of yarns is printed and dyed, the operator can install a new group of wire transfer rollers 10 and wire take-up rollers 20 on the first threaded socket column 3 and the second threaded socket column 5 respectively, and start the motor body 421 by connecting the output ends of the yarns to the rubber connecting rod 842 respectively. The output end of the motor body 421 can drive the drive shaft 422 to rotate. At this time, the drive shaft 422 will drive the drive roller 82 to rotate through the transmission belt 432, so that the threading transmission belt 84 can move, and can simultaneously drive multiple groups of yarns to bypass the anti-wear roller 7 and the support roller 6 respectively to reach the position of the wire take-up roller 20. This arrangement not only realizes the multi-purpose use of one machine, but also ensures that when there is a dye in the inner cavity of the storage groove 111, the yarn can be automatically loaded without releasing the dye, thereby improving the printing and dyeing efficiency and facilitating use.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
