Description

Technical Field

[0002] In the production process of nylon POY yarn, by directly adding a quantitative high-efficiency antibacterial agent to the polymer melt and ensuring that it is fully and evenly mixed with the melt before spinning after melt extrusion, and then using precise spinning technology and optimized spinning oil formulations, the antibacterial component can be effectively integrated into each fiber. This strategy not only improves the hygienic properties of the final textile, inhibits bacterial growth, and reduces odor, but also extends the service life of the product while maintaining the inherent strength and comfort of nylon, meeting the needs of the modern textile field for high-performance, long-lasting antibacterial materials, especially in the fields of sportswear, medical textiles and household products.

[0003] At present, direct injection is adopted when adding antimicrobial agents to the melt in the production of nylon POY yarns. The antimicrobial agents are often directly introduced into the high-speed flowing polymer melt flow through a single inlet. This method has several disadvantages: First, due to the local high concentration at the injection point, the antimicrobial agent is easy to form tiny agglomerates in the melt, rather than uniform dispersion, resulting in discontinuous distribution of the antimicrobial agent in the final fiber, affecting the overall antimicrobial efficacy and durability of the fiber. Secondly, the impact force of direct injection may destroy the stable flow of the melt, cause flow field disorder, increase unstable factors in the spinning process, such as increased broken wire rate, and affect production continuity and efficiency. Therefore, improving the injection method of the antimicrobial agent and achieving its uniform dispersion in the melt is crucial to improving the comprehensive performance of nylon POY yarns.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0017] See also Figure 1-3The utility model provides a technical solution: a nylon POY yarn antibacterial agent injection device, comprising a tube body 1, on which a metering pump 2 and a dynamic mixer 3 are respectively connected and installed. The metering pump 2 adopts a precisely controlled metering pump, which can flexibly adjust the injection rate of the antibacterial agent according to actual production needs to ensure accurate control of the injection amount. The dynamic mixer 3 is configured at the end of the tube body 1, and uses turbine blades or static mixing elements to promote the pre-mixing of the antibacterial agent and a small amount of melt to ensure that the antibacterial agent reaches a preliminary uniform state before being incorporated into the main melt. The liquid outlet of the dynamic mixer 3 is connected to a hose 4, and the end of the hose 4 is connected to an injection pipe 5. The connection between the liquid outlet of the dynamic mixer 3, the hose 4 and the injection pipe 5 is sealed, and the external design of the injection pipe 5 There is a mounting sleeve 6, one side of the outside of the mounting sleeve 6 is fixed with a stepper motor 7 by bolts, the inside of the mounting sleeve 6 is provided with a round support plate 8 driven to rotate by the stepper motor 7, both sides of the round support plate 8 are connected to the inner walls of the mounting sleeve 6 on both sides through a rotating shaft, the output end of the stepper motor 7 is connected to the rotating shaft on one side of the round support plate 8, and a through hole is provided at the center of the round support plate 8, and the through hole at the center of the round support plate 8 is symmetrically provided with a fastening plate 9 for clamping the injection tube 5. The mounting sleeve 6 of this structure can be pre-fixed and connected to the pipe mouth of the main melt flow path, and the injection tube 5 is extended into the mounting sleeve 6 and passed through the through hole on the round support plate 8. The fastening plate 9 arranged in the through hole of the round support plate 8 can quickly clamp and fix the injection tube 5. When the antibacterial agent in the tube body 1 passes through the metering pump 2 and the dynamic mixer 3 are transported to the injection tube 5, the stepper motor 7 can drive the circular support plate 8 to shake back and forth to a certain extent by driving the outside of the mounting sleeve 6, so that the injection tube 5 can adjust the injection angle in real time to ensure that the antibacterial agent is slowly introduced under mild conditions, avoiding violent disturbances to the flow of the main melt, so as to achieve a better uniform dispersion effect, which is beneficial to improving the comprehensive performance of the nylon POY yarn. The fastening plate 9 is an arc-shaped structure as a whole, and the fastening plate 9 is symmetrically distributed in the perforation at the center of the circular support plate 8 in a vertical state. The inner walls of both sides of the perforation at the center of the circular support plate 8 are bonded and fixed with elastic sponge pads 10 of the same arc-shaped structure, and the inner wall of the elastic sponge pad 10 is in contact with the outer wall of the fastening plate 9. The two fastening plates of this structure The plates 9 can cooperate with each other and generate lateral expansion and contraction force under the elastic force of the elastic sponge pad 10 to firmly clamp and fix the injection tube 5 to ensure the stability of the injection tube 5 when injecting the antibacterial agent. The upper and lower ends of the perforation at the center of the round support plate 8 are symmetrically welded and fixed with fixed sleeves 11, and the interior of the fixed sleeve 11 is laterally movably interspersed with a horizontal axis 12. The inner ends of the horizontal axis 12 are connected to the positions corresponding to the fastening plates 9 by welding, and the outer sleeve of the outer end of the horizontal axis 12 is provided with a compression spring 13. In this structure, when the injection tube 5 squeezes the inner walls of the two fastening plates 9, the fastening plates 9 will drive the horizontal axis 12 to slide inside the fixed sleeve 11 to a certain extent and squeeze the compression spring 13 when the force is applied to the fastening plates 9, until the injection tube 5 is placed as a whole at a suitable position between the fastening plates 9.The fastening plate 9 can clamp and fix the injection tube 5 more firmly under the force of the compression spring 13, further ensuring the stability of the injection tube 5 when in use.

[0018] Working principle: When using the nylon POY antimicrobial agent injection device, first, the installation sleeve 6 can be fixed to the pipe mouth of the main melt flow path through the installation hole on the horizontal side of the bottom end with bolts, and then the injection pipe 5 is inserted into the installation sleeve 6 and passes through the perforation on the round support plate 8. At this time, the injection pipe 5 will squeeze the inner walls of the two fastening plates 9. When the fastening plates 9 are stressed, they will elastically squeeze the elastic sponge pad 10, and when the fastening plates 9 are stressed, they will also drive the horizontal shaft 12 to slide inside the fixed sleeve 11 to a certain extent. When the horizontal shaft 12 slides, it will also squeeze the compression spring 13. Press until the injection tube 5 is placed in a suitable position between the two fastening plates 9 as a whole. The fastening plate 9 can firmly clamp and fix the injection tube 5 under the action of the compression spring 13 and the elastic sponge pad 10. When the antibacterial agent in the tube body 1 is transported to the injection tube 5 through the metering pump 2, the dynamic mixer 3 and the hose 4, the stepper motor 7 is started. When the stepper motor 7 is driven outside the mounting sleeve 6, it will drive the round support plate 8 to swing back and forth in an orderly manner. In this way, the injection tube 5 can change the injection angle in real time, so that the antibacterial agent slowly flows into the main melt, thereby completing a series of tasks.
