Utility Model Content

[0005] The main purpose of the utility model is to provide a spinning manifold for composite fibers, which can effectively solve the problem that the design and manufacture of spinning manifolds in the background technology at this stage have made certain progress, but there are still great limitations in structure and process.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) When the utility model is used, firstly, the corresponding motor is started according to production needs, so that the spinning solution in the feed pipe can enter the spinning device that needs to be spun through the receiving pipe body and the second feeding pipe, while the motor at the spinning device that does not need to be spun is not started. Then, different types of special filaments or fibers can be produced by using different spinning devices.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 and Figure 2As shown, a spinning manifold for composite fibers comprises a spinning manifold body 1, wherein a first feed pipe 2 and a discharge pipe 3 are arranged on the spinning manifold body 1, a delivery pipe 4 is arranged on one side of the discharge pipe 3, a plurality of receiving pipes 5 are arranged on the delivery pipe, a second feed pipe 6 is arranged on one side of the receiving pipe 5, a first semicircular stopper 7 is fixedly arranged in the inner cavity of the second feed pipe 6, a first sealing layer 8 is arranged on the side of the second feed pipe 6 close to the receiving pipe 5, a spinneret device 9 is fixedly arranged on one side of the second feed pipe 6, and a ring blowing device 10 is arranged on one side of the spinneret device 9.

[0024] like Figure 3 and Figure 4 As shown, in another embodiment of the utility model, the material receiving pipe 5 includes a material receiving pipe body 501, and a second semicircular stopper 502 is fixedly provided in the inner cavity of the material receiving pipe body 501;

[0025] The outer wall of the receiving pipe body 501 is fixedly provided with a gear ring 503;

[0026] A gear 504 is meshed with one side of the gear ring 503, and a rotating column 505 is arranged on the gear 504. A motor 506 is arranged on the rotating column 505. When the spinning solution in the feed pipe 4 needs to be transported to the spinneret 9, the motor 506 is first started, and the rotating column 505 is rotated by the motor 506. The rotating column 505 drives the gear 504 to rotate, and the gear 504 drives the gear ring 503 to rotate. The gear ring 503 drives the material receiving pipe body 501 to rotate, so that the material receiving pipe body 501 rotates 180 degrees, and the second semicircular stopper 502 on the material receiving pipe body 501 is rotated to be directly below the first semicircular stopper 7 on the second feed pipe 6. At this time, the inner cavity of the receiving tube body 501 is interconnected with the inner cavity of the second feeding tube 6, so that the spinning solution in the delivery tube 4 can enter the spinneret 9 through the receiving tube body 501 and the second feeding tube 6. When it is necessary to prevent the spinning solution in the delivery tube 4 from entering the spinneret 9, the receiving tube body 501 is rotated one hundred and eighty degrees again. At this time, the second semicircular stopper 502 on the receiving tube body 501 will be located directly below the inner cavity through which the second feeding tube 6 can flow, thereby blocking the inner cavity through which the second feeding tube 6 can flow, so that the spinning solution in the delivery tube 4 cannot enter the spinneret 9, so that the spinneret 9 can be changed in time according to production needs.

[0027] The working principle of the spinning box of a composite fiber:

[0028] When in use, first start the corresponding motor 506 according to production needs, rotate the receiving tube body 501 180 degrees, rotate the second semicircular stopper 502 on the receiving tube body 501 to just below the first semicircular stopper 7 on the second feed tube 6, at this time, the inner cavity of the receiving tube body 501 and the inner cavity of the second feed tube 6 are interconnected, so that the spinning solution in the delivery tube 4 can enter the spinning device 9 that needs to be spun through the receiving tube body 501 and the second feed tube 6, while the motor 506 at the spinning device 9 that does not need to be spun is not started, and then the spinning solution enters the spinning box body 1 through the first feed tube 2, and then the spinning solution is processed through the spinning box body 1, and the processed spinning solution passes through The discharge pipe 3 enters the feed pipe 4, and then the spinning solution is injected into several spinnerets 9 through the feed pipe 4, the receiving pipe body 501, and the second feed pipe 6. Different types of special filaments or fibers are produced by different spinnerets 9, and the finished products are then cooled by the annular blowing device 10. When it is necessary to change a certain spinneret 9, it is only necessary to rotate the corresponding receiving pipe body 501 one hundred and eighty degrees again, so that the spinning solution in the feed pipe 4 cannot enter the spinneret 9, so that a certain spinneret 9 can be changed in time according to production needs, and it can be flexibly configured according to production needs, so that special filaments or fibers of different sizes can be produced according to production needs, thereby improving production efficiency and quality.

[0029] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
