Description

Technical Field

[0001] This invention relates to the field of polyester production technology, and in particular to a production system for colored POY polyester filament. Background Technology

[0002] In the textile industry, polyester filament is an extremely important raw material with a wide range of applications. Traditional POY polyester filament is mostly plain white or requires subsequent dyeing. However, the demand for direct production of colored POY polyester filament is constantly growing. Colored POY polyester filament is made from polyester chips as the main raw material by adding specific color masterbatch or special dyeing technology. It can present rich colors, and the dyeing is uniform and of excellent performance. It also meets the concept of environmental protection and is widely used in textiles, clothing and other fields.

[0003] Chinese patent CN222294269U discloses a device for producing colored polyester POY yarn, including a heating chamber. Support columns are installed at the top and bottom of one side of the heating chamber. A motor is installed at the middle of the top of the heating chamber, and a threaded rod is installed at the output end of the motor. A raw material inlet and a colored masterbatch inlet are respectively installed at the top and middle of the other side of the heating chamber. Heating tubes are installed at the top and middle of the outer surface of the heating chamber. This device allows polyester POY raw materials and colored masterbatch to be fed into the heating chamber, and the heating chamber is heated by the heating tubes to melt the raw materials and masterbatch. Simultaneously, the melted polyester POY raw materials and colored masterbatch are mixed through the cooperation between the motor and the threaded rod. The mixed material is discharged through the outlet and then cooled and shaped by a spiral copper tube. This eliminates the need for multiple processing devices, reducing the production cost of colored polyester POY yarn.

[0004] However, in actual use, it was found that the device uses the method of mixing the color masterbatch first and then heating it. Because the color masterbatch is granular, there is a lack of effective pre-dispersion means during the initial mixing, making it difficult to fully disperse evenly. During the heating process, the situation worsens, and the different colors of the color masterbatch cannot be ideally blended. This leads to an imbalance in the color ratio of the filament during spinning, making it impossible to ensure uniform mixing of multiple colors, which easily produces color differences and affects the appearance and quality of the product. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a production system for colored POY polyester filament. This system utilizes a heating component in the feeding mechanism and a mixing and fixing plate in the mixing mechanism to ensure thorough and uniform mixing of the masterbatch, reducing color difference and efficiently producing colored POY polyester filament. This solves problems in existing technologies such as uneven masterbatch mixing, color difference affecting product appearance and quality, and issues related to moisture and high-temperature decomposition during processing.

[0026] Preferably, the heating assembly includes:

[0027] A heating wire is disposed in the inner interlayer of the feeding hopper;

[0028] An air pump is installed on the feeding hopper, and the air inlet of the air pump is connected to the inside of the feeding hopper.

[0029] Preferably, the mixing mechanism includes:

[0031] A connecting support base is provided on the mixing tank;

[0032] A hybrid motor, which is mounted on the connecting support base;

[0033] A rotating roller, which is connected to the output shaft of the hybrid motor;

[0034] A stirring blade, wherein multiple sets of the stirring blade are arranged along the circumference of the rotating roller;

[0035] A fixing plate, wherein multiple sets of fixing plates are arranged circumferentially on the inner wall of the mixing tank;

[0036] The feed pipe is connected to the bottom of the mixing tank.

[0037] Preferably, the extrusion mechanism includes:

[0038] The push chamber is provided with a connection port, which is connected to the feeding pipe, and an insulation box is also fitted onto the push chamber;

[0039] Propulsion motor;

[0040] A spiral pusher blade, wherein the spiral pusher blade is connected to the output shaft of the propulsion motor;

[0041] An extrusion connecting pipe is connected to the propulsion chamber.

[0042] Preferably, the extrusion mechanism includes:

[0043] A wire extrusion assembly, which is disposed on the extrusion connecting pipe;

[0044] A cooling air assembly is disposed on the extrusion assembly;

[0045] The molten masterbatch enters the extrusion assembly through the extrusion connecting pipe, is extruded into fine filaments, and is cooled and shaped by the cold air assembly.

[0046] Preferably, the extrusion assembly includes:

[0047] The extrusion chamber is connected to the extrusion connecting pipe;

[0048] The filament outlets are arranged in a ring and multiple sets are provided;

[0049] An isolation cover is disposed at the bottom of the extrusion chamber.

[0050] Preferably, the cooling air assembly includes:

[0051] A bellows, which is disposed on the extrusion chamber;

[0052] An air pump, which is mounted on the bellows;

[0053] An air outlet pipe is located inside the annular arrangement of the wire outlets.

[0054] Preferably, the air outlet pipe is connected to the inside of the air box.

[0055] The beneficial effects of this invention are as follows:

[0056] (1) By setting up a feeding mechanism, the color masterbatch of different colors is heated first, and the granular color masterbatch raw material is heated into a molten state and then quantitatively conveyed for mixing. By controlling the pushing speed of the forward spiral blade, the proportion of color masterbatch of various colors is adjusted, and the quantitative control of each color is carried out to ensure the stability of the final mixed color.

[0057] (2) The present invention continuously flips the masterbatch at the bottom of the feeding bucket to the top through the feeding component in the feeding component, thereby discharging the water vapor mixed in the masterbatch (water vapor generated after the water in the masterbatch is heated) and, together with the low-pressure environment created by the air pump, better absorbs the water vapor, avoiding the water from causing melt hydrolysis and fiber defects.

[0058] (3) By setting up a mixing mechanism, the present invention uses multiple sets of stirring plates and fixing plates to mix various molten masterbatches evenly as they flow downwards. The uniform mixing of the masterbatches is due to the following three points: First, it is coordinated with the feeding mechanism and uses molten masterbatches, which is more conducive to uniform mixing; second, it increases the flow path of the molten masterbatches, allowing them to shuttle between the stirring plates and the feeding pipe, and reduces the flow speed of the molten masterbatches, providing more mixing time and more thorough mixing; third, by designing the stirring plates and fixing plates to be small and numerous, the molten masterbatches can be more dispersed, resulting in more uniform color mixing.

[0059] (4) By setting up an extrusion mechanism, the present invention pushes only the molten masterbatch, which can use a lower rotation speed, reduce frictional heat generation, and avoid the decomposition of the masterbatch under high temperature processing, which would cause the fiber to yellow and its strength to decrease.

[0060] (5) By setting up an extrusion mechanism, the present invention rapidly cools the masterbatch by using cold air around it when it is extruded, so that it can be rapidly cooled and formed.

[0061] In summary, the present invention has the advantages of high color uniformity, high energy efficiency, and strong production adaptability. Attached Figure Description

[0080] Example 1

[0081] like Figures 1 to 2 As shown, this embodiment provides a production system for colored POY polyester filament, including:

[0082] Feeding mechanism 1;

[0083] A mixing mechanism 2 is disposed on the feeding mechanism 1;

[0084] Extrusion mechanism 3, which is disposed on the mixing mechanism 2;

[0085] Extrusion mechanism 4, which is disposed on extrusion mechanism 3;

[0086] After the raw materials of various colors of masterbatch are heated and the moisture is removed by the feeding mechanism 1, the molten masterbatch is quantitatively conveyed to the mixing mechanism 2 for uniform mixing to reduce color difference. Then, the molten masterbatch is conveyed to the extrusion mechanism 4 by the extrusion mechanism 3 for extrusion and cooling and shaping.

[0087] Furthermore, such as Figures 3 to 4 As shown, the feeding mechanism 1 includes: a feeding assembly 11;

[0088] Heating component 12, the heating component 12 being disposed on the feeding component 11;

[0089] The heating component 12 heats the granular masterbatch into a molten state and then conveys it quantitatively through the feeding component 11, adjusting the proportion of masterbatch of various colors as needed.

[0090] In this embodiment, the feeding component 11 and the heating component 12 in the feeding mechanism 1 cooperate with each other to achieve the functions of heating and melting granular masterbatch, quantitatively conveying and precisely adjusting the proportion of masterbatch, thereby ensuring the color stability of colored POY polyester filament and improving product quality.

[0091] Furthermore, such as Figures 3 to 4 As shown, the feeding assembly 11 includes:

[0092] Storage bin 111, the bottom of which is set as a cone shape more suitable for material feeding;

[0093] Feed connection pipe 112, the feed connection pipe 112 is connected to the bottom of the storage tank 111;

[0094] Solenoid valve 113, wherein the solenoid valve 113 is disposed on the feed connection pipe 112;

[0095] The feeding hopper 114 is provided with a feeding port 1141, and the feeding port 1141 is connected to the feeding connecting pipe 112; the feeding hopper 114 has a structure with a small bottom and a large top, wherein the small bottom part is the feeding and pushing section, and the large top part is the material exhaust and mixing section.

[0096] Stepper motor 115, the stepper motor 115 is mounted on the feeding hopper 114;

[0097] Rotating rod 116, which is connected to stepper motor 115 and extends into the feed hopper 114;

[0098] A reverse spiral blade 117 is disposed at the upper end of the rotating rod 116. The reverse spiral blade 117 is disposed in the material exhaust mixing section, which tumbles the material from the center outward to fully expel the gas inside the material. Specifically, during the initial melting process of the material, the gas trapped between the color masterbatch particles is not easy to be discharged outward. By tumbling from the center outward and negative pressure exhaust, the gas trapped between the color masterbatch particles is fully discharged, avoiding the backward transmission of bubbles that cannot be discharged and affect the quality of polyester filament.

[0099] A forward spiral blade 118 is disposed at the bottom of the rotating rod 116 for pushing the material forward downwards. The forward spiral blade 118 is disposed at the bottom pushing section of the feeding hopper 114.

[0100] The discharge connection pipe 119 is connected to the bottom of the discharge bucket 114.

[0101] In this embodiment, the feeding component 11 enables the storage, pre-treatment before heating, and quantitative conveying of granular masterbatches of different colors, thereby providing masterbatches precisely for subsequent mixing processes and ensuring the stability and reliability of the color of colored POY polyester filaments.

[0102] In detail, the conical design at the bottom of the storage tank 111 allows the masterbatch to slide smoothly down to the feed connection pipe 112 using gravity. The feed connection pipe 112 connects the storage tank 111 and the discharge tank 114, serving as the conveying channel for the masterbatch. The solenoid valve 113 is installed on it to control the timing and amount of the masterbatch entering the discharge tank 114. The feeding situation of the masterbatch can be flexibly adjusted according to the production rhythm. The discharge tank 114 is a place for temporary storage and pre-treatment of the masterbatch. The feed port 1141 is connected to the feed connection pipe 112 to ensure that the masterbatch enters smoothly.

[0103] A stepper motor 115 mounted on the feeding hopper 114 drives a rotating rod 116 to rotate. The reverse spiral blade 117 and the forward spiral blade 118 on the rotating rod 116 play different roles during rotation. The reverse spiral blade 117 flips the masterbatch at the bottom of the feeding hopper 114 upwards, which makes the masterbatch heat more evenly and allows the moisture in the masterbatch to be more easily discharged during subsequent heating, thus preventing moisture from affecting the quality of the filament. The forward spiral blade 118 pushes the flipped masterbatch towards the discharge connecting pipe 119. By precisely controlling the speed and rotation time of the stepper motor 115, the amount of masterbatch pushed by the forward spiral blade 118 can be precisely controlled, thereby achieving precise adjustment of the proportion of masterbatch of different colors. Finally, the masterbatch is transported to the subsequent process through the discharge connecting pipe 119, providing a stable and accurately proportioned masterbatch for the mixing mechanism and ensuring the color consistency of the colored POY polyester filament.

[0104] Furthermore, such as Figures 3 to 4 As shown, the heating assembly 12 includes:

[0105] Heating wire 121 is disposed in the internal interlayer of the feeding barrel 114;

[0106] An air pump 122 is installed on the feeding hopper 114, and the air inlet of the air pump 122 is connected to the inside of the feeding hopper 114.

[0107] In this embodiment, the heating wire 121 and the vacuum pump 122 of the heating component 12 work together to heat and melt the granular masterbatch in the feeding barrel 114 and remove moisture, thereby providing dry and well-melted masterbatch for subsequent processes and ensuring the quality of colored POY polyester filament.

[0108] In detail, the heating wire 121 is located in the inner layer of the feeding barrel 114. When the heating wire 121 is energized, it generates heat, which is evenly transferred to the granular masterbatch inside the feeding barrel 114. Because the heating wire is distributed in the inner layer, the masterbatch is heated relatively evenly, gradually heating the granular masterbatch into a molten state, preparing it for subsequent mixing and extrusion processes. The vacuum pump 122 is located on the feeding barrel 114, and its air inlet is connected to the inside of the feeding barrel 114. During the heating process of the masterbatch by the heating wire, the moisture in the masterbatch will turn into water vapor. The vacuum pump 122 starts to work and extracts the water vapor from the feeding barrel 114 through the air inlet. In this way, moisture is avoided from remaining in the molten masterbatch, preventing melt hydrolysis caused by moisture and avoiding quality problems such as bubbles and reduced strength in the filament. Through the coordinated work of the heating wire 121 and the vacuum pump 122, the masterbatch is ensured to enter the subsequent processes in good condition, improving the production quality of colored POY polyester filament.

[0109] Furthermore, such as Figures 8 to 9 As shown, the extrusion mechanism 3 includes:

[0110] The push chamber 301 is provided with a connection port 3011, which is connected to the feed pipe 207. The push chamber 301 is also fitted with a heat preservation box 3012.

[0111] Propulsion motor 302;

[0112] The spiral pusher 303 is connected to the output shaft of the propulsion motor 302; preferably, the spiral pusher 303 can be selected for single spiral conveying, double spiral conveying, or spiral conveying with a conical structure, and can be adapted to different material characteristics.

[0113] An extrusion connecting pipe 304 is connected to the propulsion chamber 301.

[0114] In this embodiment, by setting the extrusion mechanism 3, the mixed molten masterbatch is stably conveyed to the extrusion mechanism 4, and the quality of the masterbatch is ensured during the conveying process. At the same time, the screw speed is reduced to reduce frictional heat generation, thereby achieving the effect of ensuring stable production of colored POY polyester filament, improving product quality, and avoiding problems such as fiber yellowing and strength reduction.

[0115] In detail, the connection port 3011 of the feeding chamber 301 is connected to the feeding pipe 207, ensuring that the uniformly mixed molten masterbatch can smoothly enter the feeding chamber 301, ensuring smooth masterbatch conveying and maintaining production continuity. The feeding motor 302 drives the spiral pusher 303 to rotate. Due to the combination of premixing and screw conveying, the feeding motor 302 does not need to operate at high speed to ensure uniform conveying of masterbatch. The feeding motor 302 operates at a low and stable speed, driving the spiral pusher 303 to uniformly push the molten masterbatch towards the extrusion connecting pipe 304 within the feeding chamber 301. This low-speed operation reduces frictional heat generation, avoids masterbatch decomposition due to high temperature, and thus prevents fiber yellowing and strength reduction, ensuring product quality.

[0116] The heat preservation box 3012 is fitted onto the feeding chamber 301. It reduces heat loss through good heat preservation performance. At the same time, a medium of a certain temperature can be introduced into the heat preservation box 3012 to ensure that the temperature inside the feeding chamber 301 is constant, so that the molten masterbatch inside the chamber maintains a suitable temperature and fluidity, providing a stable quality raw material for the extrusion process. The extrusion connecting pipe 304 is connected to the feeding chamber 301, and smoothly transports the molten masterbatch pushed by the spiral pusher 303 to the extrusion mechanism 4.

[0117] Furthermore, such as Figures 10 to 11 As shown, the extrusion mechanism 4 includes:

[0118] Extrusion assembly 41, the feed end of which is connected to the discharge end of the extrusion connecting pipe 304;

[0119] A cooling air assembly 42 is disposed on the extrusion assembly 41;

[0120] The molten masterbatch enters the extrusion assembly 41 through the extrusion connecting pipe 304, is extruded into fine filaments, and is cooled and shaped by the cold air assembly 42.

[0121] In this embodiment, the extrusion assembly 41 and the cooling air assembly 42 work together to extrude the molten masterbatch conveyed from the extrusion connecting pipe 304 into fine filaments and cool and shape them, thereby producing colored POY polyester filaments that meet the specifications and improving product molding quality and production efficiency.

[0122] In detail, the extrusion assembly 41 is connected to the extrusion connecting pipe 304, allowing the molten masterbatch conveyed from the extrusion mechanism to smoothly enter the extrusion assembly 41. The extrusion assembly 41 performs an extrusion action, extruding the molten masterbatch into fine filaments. This process ensures the initial formation of the filament. The cooling air assembly 42 is installed on the extrusion assembly 41. After the masterbatch is extruded into fine filaments and flows out, the cooling air assembly 42 promptly blows out cold air to cool the filaments. This cooling method enables the filaments to cool down and set rapidly, ensuring the stability of the shape and performance of the filament. The cooperation between the extrusion assembly 41 and the cooling air assembly 42 makes the filament forming process more efficient and stable, avoiding problems such as deformation of the filament during the forming process.

[0123] Furthermore, such as Figures 10 to 11 As shown, the extrusion assembly 41 includes:

[0124] Extrusion chamber 411, which is connected to the extrusion connecting pipe 304;

[0125] The filament outlet 412 is arranged in a ring and multiple sets are provided;

[0126] An isolation cover 413 is disposed at the bottom of the extrusion chamber 411.

[0127] In this embodiment, the extrusion chamber 411, the filament outlet 412, and the isolation cover 413 of the extrusion assembly 41 work together to uniformly extrude the molten masterbatch entering the extrusion chamber 411 into fine filaments and prevent external impurities from mixing in, thereby achieving the effect of producing high-quality, pure colored POY polyester filaments.

[0128] In detail, the extrusion chamber 411 is connected to the extrusion connecting pipe 304 to ensure that the molten masterbatch conveyed from the extrusion mechanism can enter smoothly. The hollow structure design inside the extrusion chamber 411 ensures that the masterbatch is under uniform pressure in the chamber, preparing for subsequent extrusion. The filament outlets 412 are arranged in a ring and multiple sets are provided. When the molten masterbatch flows to the filament outlets 412 under the pressure in the extrusion chamber 411, the ring-shaped arrangement of the filament outlets 412 allows the masterbatch to be uniformly extruded into multiple fine filaments, ensuring the consistency and uniformity of the filaments. The isolation cover 413 is set at the bottom of the extrusion chamber 411. It can effectively block external dust, impurities, etc., and prevent these impurities from mixing into the masterbatch during the extrusion process, thereby ensuring the purity of the colored POY polyester filaments and improving product quality.

[0129] Furthermore, such as Figures 10 to 11 As shown, the cooling air assembly 42 includes:

[0130] A bellows 421 is disposed on the extrusion chamber 411;

[0131] Air pump 422, which is mounted on the bellows 421;

[0132] Air outlet 423, which is located inside the annularly arranged wire outlet 412.

[0133] In this embodiment, the cooling air assembly 42 and the extrusion assembly 41 work together to achieve rapid cooling and shaping of the colored POY polyester filament extruded from the extrusion assembly, thereby improving the physical properties of the filament, ensuring product quality stability and production efficiency.

[0134] In detail, the bellows 421 is positioned on the extrusion chamber 411. This positioning facilitates direct application of cold air to the filaments extruded from the filament outlet 412 of the extrusion chamber 411. The air pump 422 is positioned on the bellows 421. When the air pump 422 operates, it pumps air into the bellows 421, making the bellows 421 a container for storing pressurized cold air. The cooperation between the air pump 422 and the bellows 421 ensures the generation and storage of cold air, guaranteeing sufficient cold air volume for filament cooling. The air outlet duct 42... Located inside the annularly arranged filament outlets 412, the cold air in the bellows 421 is blown out through the air outlet 423. Due to the design of the air outlet 423, the blown cold air can evenly surround the filaments extruded from the filament outlets 412, quickly removing the heat from the filaments. The cooperation between the air outlet 423 and the filament outlets 412 achieves precise cooling of the filaments by the cold air, allowing the filaments to cool and solidify quickly, which helps to improve the strength and stability of the filaments and avoid problems such as deformation of the filaments during the forming process.

[0135] Furthermore, such as Figures 10 to 11 As shown, the air outlet pipe 423 is connected to the interior of the air box 421.

[0136] In this embodiment, the connection between the air outlet duct 423 and the air box 421, in conjunction with the extrusion assembly 41, enables the precise guidance and blowing of the cold air inside the air box 421 to the freshly extruded colored POY polyester filament for cooling and shaping, thereby ensuring rapid filament forming, improving product quality and production efficiency.

[0137] In detail, the bellows 421, as a storage container for cold air, provides a cold source for filament cooling. The air outlet 423 is connected to the inside of the bellows 421. Under the pressure generated by the air pump 422, the cold air in the bellows 421 flows along the air outlet 423. Since the air outlet 423 is located inside the annularly arranged filament outlets 412, the cold air flowing out from the air outlet 423 can directly and evenly blow onto the molten filaments extruded from the filament outlets 412. The connection between the bellows 421 and the air outlet 423 ensures that the cold air can be continuously and stably supplied to the filaments, achieving rapid cooling of the filaments. This cooling method enables the filaments to cool down and solidify quickly, effectively avoiding deformation of the filaments under gravity or quality problems caused by untimely cooling, and greatly improving the quality and stability of the filaments.

For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0140] The hybrid mechanism 2 includes:

[0141] Mixing tank 201; The mixing tank 201 is provided with a discharge port 2011, and the discharge port 2011 is connected to the discharge connecting pipe 119;

[0142] A connecting support 202 is provided on the mixing tank 201;

[0143] Hybrid motor 203, the hybrid motor 203 is mounted on the connecting support 202;

[0144] Rotary roller 204 is connected to the output shaft of the hybrid motor 203 via a transmission connection.

[0145] A stirring blade 205 is provided, and multiple sets of stirring blades 205 are arranged along the circumference of the rotating roller 204, forming a material channel between adjacent stirring blades 205 in the circumferential direction.

[0146] Fixing plate 206, multiple sets of fixing plates 206 are arranged circumferentially on the inner wall of the mixing tank 201, and are spaced apart from the stirring plate 205 along the axial direction of the rotating roller 204;

[0147] Feed pipe 207 is connected to the bottom of mixing tank 201.

[0148] In this embodiment, the mixing barrel 201 of the mixing mechanism 2 is connected to the discharge connection pipe 119 to receive the molten masterbatch conveyed by the feeding mechanism 1. Then, the mixing motor 203 drives the rotating roller 204 and the stirring plate 205, which, together with the fixing plate 206 on the inner wall of the mixing barrel 201, achieve the function of uniformly mixing the molten masterbatch, thereby reducing the color difference of colored POY polyester filament and improving the color quality of the product.

[0149] In detail, the discharge port 2011 of the mixing tank 201 is connected to the discharge connecting pipe 119, allowing the molten masterbatch of different colors conveyed by the feeding mechanism to smoothly enter the mixing tank 201. The connecting support 202 is set on the mixing tank 201 to provide a stable installation base for the mixing motor 203, ensuring the smooth operation of the mixing motor 203. After the mixing motor 203 starts, its output shaft drives the rotating roller 204 to rotate, and the stirring blade 205 on the rotating roller 204 rotates accordingly. The stirring blade 205 cooperates with the fixed plate 206. When the stirring blade 205 rotates and pushes the molten masterbatch to flow, the fixed plate 206 blocks the masterbatch, changing the flow direction and path of the masterbatch, so that the masterbatch forms a complex flow trajectory in the mixing tank 201, increasing the collision and contact opportunities between the masterbatches, allowing the masterbatches of different colors to be fully and evenly mixed. This cooperation method can effectively improve the mixing efficiency and quality and avoid uneven color. Finally, the evenly mixed masterbatch is conveyed to the subsequent process through the discharge pipe 207 connected to the bottom of the mixing tank 201.

[0150] Furthermore, since the materials generate heat during the mixing process, a cooling component is also provided on the outside of the mixing tank 201 to maintain a constant temperature inside the mixing tank 201. This technology is prior art, and the detailed structure will not be described in detail here. For example, a spiral cooling water pipe is arranged circumferentially on the outer wall of the mixing tank 201 to cool the mixing tank 201 through medium heat exchange.

[0151] Work steps

[0152] Color masterbatch raw materials of various colors first enter the feeding mechanism 1. In the feeding mechanism 1, they are heated by the heating wire 121 and the moisture is removed by the vacuum pump 122. After becoming molten, they are quantitatively conveyed to the mixing mechanism 2 through the feed connection pipe 112 and the discharge connection pipe 119. The mixing tank 201 of the mixing mechanism 2 receives the color masterbatch. The mixing motor 203 drives the rotating roller 204 and the stirring blade 205 to rotate. The stirring blade 205 cooperates with the fixing plate 206 on the inner wall of the mixing tank 201 to evenly distribute the color masterbatch. After uniform mixing to reduce color difference, the mixed molten masterbatch enters the pushing chamber 301 of the extrusion mechanism 3. The pushing motor 302 drives the spiral pusher 303 to push it to the extrusion connecting pipe 304. Finally, the masterbatch enters the extrusion assembly 41 of the extrusion mechanism 4 and is extruded into fine filaments from the filament outlet 412 through the extrusion chamber 411. The air box 421, air pump 422 and air outlet pipe 423 of the cold air assembly 42 work together to blow out cold air to cool and shape the fine filaments, thus producing colored POY polyester filaments.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
