Description

Technical Field

[0001] The invention relates to the technical field of polyester production, in particular to a production system of colored POY polyester filaments. Background Art

[0002] In the textile industry, polyester filament is an extremely important raw material and is widely used. Traditional POY polyester filament is mostly conventional white or requires subsequent dyeing processing, but nowadays the demand for direct production of colored POY polyester filament is growing. Colored POY polyester filament uses polyester chips as the main raw material and is made by adding specific masterbatch or special dyeing technology. It can present rich colors, uniform dyeing, excellent performance, and is in line with environmental protection concepts. It is widely used in many fields such as textiles and clothing.

[0003] Chinese patent CN222294269U discloses a polyester POY colored yarn production device, including a heating cavity, the top and bottom of one side of the heating cavity are both equipped with support columns, the middle position of the top of the heating cavity is equipped with a motor, the output end of the motor is equipped with a threaded rod, the top and middle positions of the other side of the heating cavity are respectively equipped with a raw material feeding port and a color masterbatch feeding port, and the top and middle positions of the outer surface of the heating cavity are both equipped with a heating tube. In this utility model, polyester POY raw materials and color masterbatches are put into the heating cavity, and the heating cavity is heated by the heating tube to melt the polyester POY raw materials and color masterbatches, and the melted polyester POY raw materials and color masterbatches are mixed by the cooperation between the motor and the threaded rod, and the mixed materials can be discharged through the discharge port, and then cooled and formed by the spiral copper tube, without the need for multiple processing equipment, thereby reducing the production cost of polyester POY colored yarn.

[0004] However, in actual use, it was found that the device used a method of mixing the masterbatch first and then heating it. Because the masterbatch is granular, there is a lack of effective pre-dispersion means during the initial mixing, making it difficult to fully and evenly disperse it. During the heating stage, the situation worsens and masterbatches of different colors cannot be ideally blended. This causes an imbalance in the color ratio of the filaments during spinning, and it is impossible to ensure uniform mixing of multiple colors, which is very likely to produce color differences and affect the appearance and quality of the product.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0026] Embodiment 1 like Figure 1 to Figure 2 As shown, this embodiment provides a production system for colored POY polyester filaments, comprising: Feeding mechanism 1; A mixing mechanism 2, wherein the mixing mechanism 2 is arranged on the feeding mechanism 1; An extruding mechanism 3, wherein the extruding mechanism 3 is arranged on the mixing mechanism 2; A wire extruding mechanism 4, wherein the wire extruding mechanism 4 is arranged on the material extruding mechanism 3; After the masterbatch raw materials of various colors are heated and the moisture is removed by the feeding mechanism 1, the molten masterbatch is quantitatively transported to the mixing mechanism 2 for uniform mixing to reduce color difference, and then the molten masterbatch is transported to the wire extrusion mechanism 4 through the extrusion mechanism 3 for wire extrusion and cooling and shaping.

[0027] Further, if Figure 3 to Figure 4 As shown, the blanking mechanism 1 comprises: a blanking component 11; A heating component 12, wherein the heating component 12 is disposed on the blanking component 11; The heating component 12 heats the granular masterbatch into a molten state and quantitatively delivers it through the feeding component 11 to adjust the proportion of the masterbatch of various colors as needed.

[0028] In this embodiment, the unloading component 11 and the heating component 12 in the unloading mechanism 1 cooperate with each other to achieve the functions of heating and melting the granular masterbatch, quantitatively conveying and accurately adjusting the masterbatch ratio, thereby achieving the effect of ensuring the color stability of the colored POY polyester filament and improving the product quality.

[0029] Further, if Figure 3 to Figure 4 As shown, the blanking assembly 11 comprises: A material storage barrel 111, the bottom of which is configured to be a cone that is more suitable for material discharge; A feed connecting pipe 112, wherein the feed connecting pipe 112 is connected to the bottom of the storage barrel 111; A solenoid valve 113, wherein the solenoid valve 113 is disposed on the feed connecting pipe 112; A material discharge barrel 114, wherein a feed port 1141 is provided on the material discharge barrel 114, and the feed port 1141 is connected to the feed connection pipe 112; the material discharge barrel 114 has a small bottom and a large top structure, wherein the small bottom portion is a feed propulsion section, and the larger top portion is a material exhaust mixing section; A stepper motor 115, wherein the stepper motor 115 is mounted on the discharge barrel 114; A rotating rod 116, the rotating rod 116 is drivingly connected to the stepping motor 115 and extends into the interior of the discharge barrel 114; The reverse spiral blade 117 is arranged at the upper end of the rotating rod 116, and turns the material from the center to the outside to fully discharge the gas in the material. The reverse spiral blade 117 is arranged in the material exhaust mixing section; specifically, during the initial melting process of the material, the gas mixed between the masterbatch particles is not convenient to be discharged outward. By turning from the center to the outside and exhausting with negative pressure, the gas mixed between the masterbatch particles is fully discharged, and it is avoided that the bubbles are transmitted backward and cannot be discharged to affect the quality of the polyester filament; A forward spiral blade 118, which is disposed at the bottom of the rotating rod 116 and is used to push the material forward downward. The forward spiral blade 118 is disposed at the bottom propulsion section of the discharge barrel 114; The discharge connecting pipe 119 is connected to the bottom of the discharge barrel 114 .

[0030] In this embodiment, the unloading component 11 is used to realize the storage, pre-heating pre-treatment, and quantitative delivery of granular masterbatches of different colors, thereby achieving the precise provision of masterbatches for subsequent mixing processes, ensuring the color stability and reliable quality of colored POY polyester filaments.

[0031] In detail, the conical design at the bottom of the storage barrel 111 utilizes gravity to allow the masterbatch to slide smoothly down to the feed connecting pipe 112. The feed connecting pipe 112 connects the storage barrel 111 with the discharge barrel 114, and is a conveying channel for the masterbatch. The solenoid valve 113 is installed thereon to control the timing and amount of the masterbatch entering the discharge barrel 114. The feeding situation of the masterbatch can be flexibly adjusted according to the production rhythm. The discharge barrel 114 is a place for temporary storage and pretreatment of the masterbatch. The feed port 1141 is connected to the feed connecting pipe 112 to ensure the smooth entry of the masterbatch.

[0032] The stepper motor 115 installed on the discharge barrel 114 drives the rotating rod 116 to rotate. The reverse spiral blades 117 and the forward spiral blades 118 on the rotating rod 116 play different roles in the rotation process. The reverse spiral blades 117 flip the masterbatch at the bottom of the discharge barrel 114 upwards, which makes the masterbatch heated more evenly on the one hand, and makes it easier to discharge the moisture in the masterbatch during subsequent heating on the other hand, so as to avoid the moisture affecting the quality of the filament; the forward spiral blades 118 push the flipped masterbatch toward the discharge connecting pipe 119. By accurately controlling the speed and rotation time of the stepper motor 115, the amount of masterbatch pushed by the forward spiral blades 118 can be accurately controlled, thereby realizing accurate adjustment of the ratio of masterbatch of different colors. Finally, the masterbatch is transported to the subsequent process through the discharge connecting pipe 119, providing the mixing mechanism with stable and accurately proportioned masterbatch, thereby ensuring the color consistency of the colored POY polyester filament.

[0033] Further, if Figure 3 to Figure 4 As shown, the heating component 12 includes: A heating wire 121, wherein the heating wire 121 is disposed in an inner interlayer of the discharge barrel 114; The air pump 122 is disposed on the lower material barrel 114 , and an air inlet of the air pump 122 is connected to the interior of the lower material barrel 114 .

[0034] In this embodiment, the heating wire 121 and the vacuum pump 122 of the heating component 12 cooperate with each other to achieve the function of heating, melting and removing moisture from the granular masterbatch in the discharge barrel 114, thereby providing dry and well-molten masterbatch for subsequent processes and ensuring the quality of colored POY polyester filaments.

[0035] In detail, the heating wire 121 is arranged in the inner interlayer of the discharge barrel 114. When the heating wire 121 is energized, heat is generated, and the heat is evenly transferred to the granular masterbatch inside the discharge barrel 114. Since the heating wires are distributed in the interlayer, the masterbatch can be heated more evenly, and the granular masterbatch is gradually heated into a molten state, so as to prepare for the subsequent mixing and extrusion processes. The vacuum pump 122 is arranged on the discharge barrel 114, and its air inlet is connected to the inside of the discharge barrel 114. In the process of the heating wire heating the masterbatch, the moisture in the masterbatch will turn into water vapor. The vacuum pump 122 starts to work and extracts the water vapor in the discharge barrel 114 through the air inlet. In this way, moisture is avoided from remaining in the molten masterbatch, melt hydrolysis caused by moisture is prevented, and quality problems such as bubbles and reduced strength of the filament are avoided. The coordinated work of the heating wire 121 and the vacuum pump 122 ensures that the masterbatch enters the subsequent process in a good state, thereby improving the production quality of the colored POY polyester filament.

[0036] Further, if Figures 8 to 9 As shown, the extrusion mechanism 3 includes: A propulsion chamber 301, wherein a connection port 3011 is provided on the propulsion chamber 301, wherein the connection port 3011 is communicated with the feed pipe 207, and an insulation box 3012 is also sleeved on the propulsion chamber 301; Propulsion motor 302; A spiral pusher 303, wherein the spiral pusher 303 is drivingly connected to the output shaft of the propulsion motor 302; preferably, the spiral pusher 303 can be selected in a single spiral conveying, a double spiral conveying, a spiral conveying with a conical structure, etc., and can be adaptively selected according to different material characteristics; An extrusion connecting tube 304 is connected to the propulsion chamber 301 .

[0037] In this embodiment, by providing an extrusion mechanism 3, the mixed molten masterbatch is stably conveyed to the extrusion mechanism 4, and the quality of the masterbatch is guaranteed during the conveying process. At the same time, the screw speed is reduced to reduce the frictional heat generation, thereby achieving the effect of ensuring the stable production of colored POY polyester filament, improving product quality, and avoiding fiber yellowing and strength reduction problems.

[0038] In detail, the connection port 3011 of the propulsion chamber 301 is connected to the discharge pipe 207 to ensure that the evenly mixed molten masterbatch can smoothly enter the propulsion chamber 301, ensure smooth transportation of the masterbatch, and maintain production continuity. The propulsion motor 302 drives the spiral push blade 303 to rotate. Due to the combination of pre-mixing and screw transmission mixing, the propulsion motor 302 does not need a high speed to ensure uniform transportation of the masterbatch. The propulsion motor 302 runs at a relatively low and stable speed, driving the spiral push blade 303 to uniformly push the molten masterbatch in the propulsion chamber 301 to move toward the extrusion connection pipe 304. This low-speed operation reduces frictional heat generation, avoids decomposition of the masterbatch due to high temperature, and prevents the fiber from yellowing and strength reduction, thereby ensuring product quality.

[0039] The insulation box 3012 is sleeved on the propulsion chamber 301, and reduces heat loss through good insulation performance. At the same time, a medium of a certain temperature can also be introduced into the insulation box 3012 to ensure that the temperature in the propulsion chamber 301 is constant, so that the molten masterbatch in the chamber maintains a suitable temperature and fluidity, providing raw materials with stable quality for the extrusion process. The extrusion connecting tube 304 is connected to the propulsion chamber 301, and the molten masterbatch pushed by the spiral push blade 303 is smoothly transported to the extrusion mechanism 4.

[0040] Further, if Figure 10 to Figure 11 As shown, the wire extrusion mechanism 4 includes: A wire extrusion assembly 41, wherein a feed end of the wire extrusion assembly 41 is connected to a discharge end of the extrusion connection tube 304; A cold air component 42, wherein the cold air component 42 is disposed on the wire extrusion component 41; The molten masterbatch enters the wire extrusion assembly 41 through the extrusion connecting tube 304 , is extruded into filaments and flows out, and is cooled and shaped by the cold air assembly 42 .

[0041] In this embodiment, through the cooperation of the extrusion component 41 and the cold air component 42, the function of extruding the molten masterbatch delivered from the extrusion connecting tube 304 into filaments and cooling and shaping is achieved, thereby achieving the effect of producing colored POY polyester filaments that meet the specifications and improving the product molding quality and production efficiency.

[0042] In detail, the wire extrusion assembly 41 is connected to the extrusion connection tube 304, so that the molten masterbatch delivered from the extrusion mechanism can smoothly enter the wire extrusion assembly 41. The wire extrusion assembly 41 plays an extrusion role to extrude the molten masterbatch into filaments. This process ensures the initial molding of the filaments. The cold air assembly 42 is arranged on the wire extrusion assembly 41. When the masterbatch is extruded into filaments and flows out, the cold air assembly 42 blows out cold air in time to cool the filaments. This cooling method can quickly cool down the filaments and shape them, ensuring the shape and performance of the filaments are stable. The cooperation of the wire extrusion assembly 41 and the cold air assembly 42 makes the molding process of the filaments more efficient and stable, avoiding the deformation of the filaments during the molding process.

[0043] Further, if Figure 10 to Figure 11 As shown, the wire extrusion assembly 41 includes: A wire extrusion chamber 411, wherein the wire extrusion chamber 411 is connected to the extrusion connection tube 304; The wire outlets 412 are arranged in a ring shape and are provided in multiple groups; The isolation cover 413 is disposed at the bottom of the wire extrusion chamber 411 .

[0044] In this embodiment, the extrusion chamber 411, the filament outlet 412 and the isolation cover 413 of the extrusion assembly 41 cooperate with each other to achieve the goal of evenly extruding the molten masterbatch entering the extrusion chamber 411 into filaments and preventing foreign impurities from mixing in, thereby achieving the effect of producing high-quality, pure colored POY polyester filaments.

[0045] In detail, the extrusion cavity 411 is connected to the extrusion connecting tube 304 to ensure that the molten masterbatch delivered from the extrusion mechanism can enter smoothly. The hollow structure design inside the extrusion cavity 411 ensures that the pressure of the masterbatch is uniform in the cavity, preparing for subsequent extrusion. The outlets 412 are arranged in a ring and are provided in multiple groups. When the molten masterbatch flows to the outlets 412 under the pressure in the extrusion cavity 411, the outlets 412 arranged in a ring allow the masterbatch to be evenly extruded into multiple filaments, ensuring the consistency and uniformity of the filaments. The isolation cover 413 is arranged at the bottom of the extrusion cavity 411, which can effectively block external dust, impurities, etc., and prevent these impurities from mixing into the masterbatch during the extrusion process of the masterbatch into filaments, thereby ensuring the purity of the colored POY polyester filaments and improving the product quality.

[0046] Further, if Figure 10 to Figure 11 As shown, the cold air component 42 includes: A bellows 421, wherein the bellows 421 is disposed on the wire extrusion chamber 411; An air pump 422, wherein the air pump 422 is disposed on the bellows 421; The air outlet pipe 423 is located inside the thread outlets 412 arranged in a ring shape.

[0047] In this embodiment, the cold air component 42 cooperates with the extrusion component 41 to achieve the function of quickly cooling and shaping the colored POY polyester filaments extruded from the extrusion component, thereby achieving the effect of improving the physical properties of the filaments, ensuring product quality stability and production efficiency.

[0048] In detail, the bellows 421 is arranged on the extrusion chamber 411. This position arrangement facilitates the cold air to directly act on the filaments extruded from the filament outlet 412 of the extrusion chamber 411. The air pump 422 is arranged on the bellows 421. When the air pump 422 is working, it pumps air into the bellows 421, so that the bellows 421 becomes a container for storing pressurized cold air. The cooperation between the air pump 422 and the bellows 421 provides a guarantee for the generation and storage of cold air, ensuring that there is enough cold air for cooling the filaments. The cold air in the bellows 421 is blown out through the air outlet 423, which is located inside the annularly arranged wire outlet 412. Due to the position design of the air outlet 423, the blown cold air can evenly surround the filaments extruded from the wire outlet 412 and quickly take away the heat of the filaments. The cooperation between the air outlet 423 and the wire outlet 412 realizes the precise cooling of the filaments by the cold air, so that the filaments can be quickly cooled and shaped, which helps to improve the strength and stability of the filaments and avoid deformation of the filaments during the molding process.

[0049] Further, if Figure 10 to Figure 11 As shown, the air outlet pipe 423 is connected to the interior of the air box 421 .

[0050] In this embodiment, through the connection design between the air outlet pipe 423 and the bellows 421, in conjunction with the wire extrusion assembly 41, the function of accurately guiding the cold air in the bellows 421 and blowing it to the freshly extruded colored POY polyester filaments for cooling and shaping is achieved, thereby ensuring the rapid molding of the filaments and improving product quality and production efficiency.

[0051] In detail, the bellows 421 serves as a storage container for cold air, providing a cold source for cooling the filaments. The air outlet pipe 423 is connected to the inside of the bellows 421. The cold air in the bellows 421 flows along the air outlet pipe 423 under the pressure generated by the air pump 422. Since the air outlet pipe 423 is located on the inner side of the annularly arranged filament outlet 412, the cold air flowing out of the air outlet pipe 423 can be directly and evenly blown onto the molten filaments extruded from the filament outlet 412. The connection between the bellows 421 and the air outlet pipe 423 ensures that the cold air can be continuously and stably supplied to the filaments, thereby achieving rapid cooling of the filaments. This cooling method can quickly cool down and solidify the filaments, effectively avoiding deformation of the filaments under the action of gravity or quality problems caused by untimely cooling, thereby greatly improving the quality and stability of the filaments.

For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that: The mixing mechanism 2 comprises: A mixing barrel 201; the mixing barrel 201 is provided with a discharge port 2011, and the discharge port 2011 is connected to the discharge connection pipe 119; A connecting support seat 202, wherein the connecting support seat 202 is disposed on the mixing barrel 201; A hybrid motor 203, wherein the hybrid motor 203 is mounted on the connecting support seat 202; A rotating roller 204, wherein the rotating roller 204 is drivingly connected to an output shaft of the hybrid motor 203; Agitating blades 205, wherein a plurality of agitating blades 205 are arranged on the rotating roller 204 along the circumference thereof, and a material channel is formed between the circumferentially adjacent agitating blades 205; The fixing plates 206 are arranged in a plurality of groups along the circumference of the inner wall of the mixing barrel 201 and are spaced apart from the stirring plates 205 along the axial direction of the rotating roller 204; A feed pipe 207 is connected to the bottom of the mixing barrel 201 .

[0053] In this embodiment, the mixing barrel 201 of the mixing mechanism 2 is connected to the discharge connecting pipe 119 to receive the molten masterbatch delivered by the unloading mechanism 1, and then the mixing motor 203 drives the rotating roller 204 and the stirring blade 205, which cooperate with the fixed plate 206 on the inner wall of the mixing barrel 201 to achieve the uniform mixing function of the molten masterbatch, thereby achieving the effect of reducing the color difference of the colored POY polyester filament and improving the color quality of the product.

[0054] In detail, the discharge port 2011 of the mixing barrel 201 is connected to the discharge connecting pipe 119, so that the molten masterbatches of different colors transported by the discharge mechanism can smoothly enter the mixing barrel 201. The connecting support seat 202 is arranged on the mixing barrel 201 to provide a stable installation foundation for the mixing motor 203 to ensure the smooth operation of the mixing motor 203. After the mixing motor 203 is started, its output shaft drives the roller 204 to rotate, and the stirring blade 205 on the roller 204 rotates accordingly. The stirring blade 205 cooperates with the fixed blade 206. When the stirring blade 205 rotates to promote the flow of the molten masterbatch, the fixed blade 206 blocks the masterbatch, changes the flow direction and path of the masterbatch, and forms a complex flow trajectory of the masterbatch in the mixing barrel 201, increases the collision and contact opportunities between the masterbatches, and allows the masterbatches of different colors to be fully and evenly mixed. This coordination method can effectively improve the mixing efficiency and quality, and avoid the occurrence of uneven colors. Finally, the evenly mixed masterbatch is transported to the subsequent process through the discharge pipe 207 connected to the bottom of the mixing barrel 201.

[0055] In addition, since the materials generate heat during the mixing process, a cooling component for maintaining a constant temperature in the mixing barrel 201 is also provided on the outside of the mixing barrel 201. This technology is prior art, and the detailed structure is not described in detail in this application. For example, a cooling water pipe with a spiral structure is arranged circumferentially on the outer wall of the mixing barrel 201 to cool the mixing barrel 201 by medium heat exchange.

[0056] Working steps The masterbatch raw materials of various colors first enter the unloading mechanism 1, and are heated by the heating wire 121 in the unloading mechanism 1 and the moisture is removed by the vacuum pump 122. After becoming a molten state, they are quantitatively transported to the mixing mechanism 2 through the feeding connecting pipe 112 and the discharging connecting pipe 119. The mixing barrel 201 of the mixing mechanism 2 receives the masterbatch, and the mixing motor 203 drives the 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 barrel 201 to evenly mix the masterbatch. After uniform mixing to reduce color difference, the mixed molten masterbatch enters the propulsion chamber 301 of the extrusion mechanism 3, and the propulsion motor 302 drives the spiral push blade 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 filaments from the filament outlet 412 through the extrusion chamber 411. The bellows 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 filaments to make colored POY polyester filaments.

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