Description

Technical Field

[0001] The present invention relates to the technical field of textile production, and particularly relates to a production device and a preparation method for lightweight warm and quick-drying polyester fibers. Background Art

[0002] In the production process of lightweight warm and quick-drying polyester fibers, in order to effectively remove impurities and oil stains in the polyester raw materials and improve their surface characteristics, a composite preparation needs to be applied to the polyester raw materials and subjected to esterification treatment.

[0003] Traditionally, when mixing polyester raw materials and the composite preparation, a static feeding method is often used, adding them into the mixing tank in different directions, and then stirring to achieve the reaction between the two. However, this method often has problems of uneven mixing and low efficiency, affecting the processing performance of the fibers, such as the stability during the spinning process, as well as the yield and quality of the fiber products.

[0004] Therefore, in view of this problem, the present invention proposes a production device and a preparation method for lightweight warm and quick-drying polyester fibers. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a production device and a preparation method for lightweight warm and quick-drying polyester fibers that can overcome the above problems or at least partially solve the above problems.

[0006] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is: a production device for lightweight warm and quick-drying polyester fibers, including a vertical mixing cylinder and a horizontal mixing cylinder connected to the bottom of the vertical mixing cylinder. A spiral stirring rod one is rotatably connected to the horizontal mixing cylinder. A spiral stirring rod two is arranged in the vertical mixing cylinder and is in linkage with the spiral stirring rod one. A discharging mechanism connected to an external spinning assembly is communicated with the horizontal mixing cylinder. The production device also includes a top plate connected to the top of the vertical mixing cylinder. A circular shell is rotatably connected to the top plate. A vertical feeding pipe is fixed on the circular shell and is inserted into the top end of the spiral stirring rod two. A plurality of discharging ports are arranged on the surface of the vertical feeding pipe in a circumferential distribution and corresponding to the inside of the vertical mixing cylinder. An annular liquid collecting cavity is formed between the surface of the vertical feeding pipe and the inside of the circular shell. A liquid inlet pipe is communicated with the top of the annular liquid collecting cavity. A plurality of liquid outlet pipes with control valves are communicated with the bottom of the annular liquid collecting cavity in a circumferential distribution. The liquid outlet ends of the liquid outlet pipes are obliquely corresponding to the front of the discharging ports.

[0007] Preferably, the vertical mixing cylinder gradually narrows from the top end diameter to the bottom end diameter of the middle section. The end diameter of the vertical mixing cylinder near the top of the middle section is the same as the bottom end diameter corresponding to the upper section of the vertical mixing cylinder, and the end diameter of the vertical mixing cylinder near the bottom of the middle section is the same as the top end diameter corresponding to the lower section of the vertical mixing cylinder.

[0008] Preferably, a driving part is installed at one end of the first spiral stirring rod extending outside the horizontal mixing cylinder. An installation ring is fixedly connected to the surface of the driving part, and a pair of horizontal connecting bars are fixedly connected between the installation ring and one side of the horizontal mixing cylinder.

[0009] Preferably, the discharging mechanism includes a receiving pipe connected to the lower surface of the horizontal mixing cylinder. The other end of the receiving pipe is connected to a metering pump, and a discharging pipe is connected to the metering pump.

[0010] Preferably, a hemispherical block is fixedly connected to the bottom wall of the vertical feeding pipe, and the top of the hemispherical block is lower than the top port of the discharging port.

[0011] Preferably, a square groove is opened at the bottom end of the vertical feeding pipe, and a square block that fits the inner wall of the square groove is fixedly connected to the top end of the second spiral stirring rod.

[0012] Preferably, a guiding block is connected to the surface of the second spiral stirring rod through a bearing. A plurality of connecting rods distributed in a circular pattern are fixed between the surface of the guiding block and the inner wall of the vertical mixing cylinder. A sealing cavity is provided in the guiding block. A first bevel gear is fixedly connected to one end of the second spiral stirring rod located inside the sealing cavity, and a transmission part is provided between the surface of the first bevel gear and the surface of the first spiral stirring rod.

[0013] Preferably, the guiding block includes a first section, a second section, and a third section. The first section corresponds to the inside of the upper section of the vertical mixing cylinder, the third section corresponds to the inside of the middle section of the vertical mixing cylinder. The top end diameter of the first section gradually increases to the bottom end diameter, and the top end diameter of the third section gradually decreases to the bottom end diameter.

[0014] Preferably, the transmission part includes a connecting shaft rotatably arranged between the guiding block and the vertical mixing cylinder. One end of the connecting shaft is fixedly connected to a second bevel gear connected to the surface of the first bevel gear. The other end of the connecting shaft is fixedly connected to a first pulley. A transmission belt adapted to the surface of the first pulley is connected to the inner surface of the transmission belt, and a second pulley adapted to the transmission belt is connected to the surface of the first spiral stirring rod.

[0015] The present invention also provides a method for preparing lightweight warm and quick-drying polyester fibers, including the following steps: S1. Prepare the polyester raw material and the composite preparation respectively, and inject the composite preparation into the annular liquid collecting cavity through the liquid inlet pipe; S2, start the spiral stirring rod 1 and the spiral stirring rod 2, so that the polyester raw material falls from the vertical feeding pipe into the vertical mixing drum through the discharge port, and at the same time, open the control valve of the liquid discharge pipe, so that the composite preparation and the raw material in the annular liquid collecting cavity are simultaneously fed into the vertical mixing drum in a rotating manner for preliminary mixing, and then the mixed raw materials enter the horizontal mixing drum for secondary mixing; S3. Finally, the raw material output is precisely controlled by the discharging mechanism and sent to the spinning assembly for spinning processing.

[0016] It should be noted that during the yarn preparation process, the yarn cross-section is designed as a unique 4C groove structure. This design gives the yarn a fluffy appearance and a huge specific surface area, which can effectively capture and lock a large amount of still air, thereby effectively slowing down heat loss and achieving excellent warmth retention. Its thermal insulation rate is increased by about 23% compared to ordinary fabrics.

[0017] In addition, the 4C groove structure not only makes the fiber appear more fluffy and light, but also through the micro-processing technology, the fiber is further reduced and presents a honeycomb porous shape, which not only greatly reduces the weight of the fabric garment, but also brings an unprecedented light-as-air wearing experience. The micro-processing process cleverly constructs a honeycomb microporous structure on the inner and outer surfaces of the 4C groove fiber. This structure uses the double siphon effect to exhibit a strong absorption, conduction, diffusion and evaporation ability for human water molecules, thereby achieving the effects of quick drying, cooling and dehumidification, allowing the body to always stay refreshed and comfortable.

[0018] In order to meet the design requirements of fabric structures in different seasons, this unique 4C microporous structure demonstrates its flexible and changeable characteristics. In spring and summer, the micropores can efficiently conduct moisture and dissipate heat, bringing a cool and refreshing feeling; in autumn and winter, the micropores can lock in a large amount of still air, achieving a light, fluffy, warm and comfortable wearing experience. Whether the human body is sweating during exercise or in a static state, this special groove and hole structure can play an excellent role. The former quickly diffuses water and uses evaporation to take away the body's heat and moisture, thereby achieving effective cooling and dehumidification. The latter relies on its huge specific surface area to firmly lock in still air and slow down heat loss, thereby maintaining the body's energy balance.

[0019] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: First of all, through the coordinated cooperation of the vertical mixing cylinder, the horizontal mixing cylinder, the first spiral stirring rod and the second spiral stirring rod, the present technical solution realizes the efficient primary and secondary mixing of polyester raw materials and composite preparations, significantly improves the mixing uniformity, and lays a solid foundation for the subsequent spinning process. Secondly, the design of the feeding pipe, the annular liquid collecting cavity, the liquid outlet pipe and the vertical feeding pipe enables the raw materials and the composite preparation to be more evenly distributed inside the vertical mixing cylinder in a rotating manner. Compared with the traditional static feeding method, it can further promote the effect of uniform mixing.

[0020] At the same time, it also avoids the problems of accumulation and blockage of raw materials during the feeding process. Finally, by adopting a composite preparation containing a variety of functional additives and synergistically acting in the production process of polyester fibers, the finally produced polyester fibers have multiple characteristics such as light weight, warmth retention, breathability, softness, antibacterial and anti-ultraviolet, improving the comprehensive performance and market competitiveness of the product.

[0023] The following further describes the present invention in detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it according to the description in the specification.

[0024] It should be understood that the terms such as "having", "including" and "comprising" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0025] In the description of the present invention, the orientation or positional relationship indicated by the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0026] Referring to Figures 1 - 8 , a production device for lightweight warm and quick-drying polyester fibers, comprising a vertical mixing cylinder 1 and a horizontal mixing cylinder 2 connected to the bottom of the vertical mixing cylinder 1. A spiral stirring rod 21 is rotatably connected to the horizontal mixing cylinder 2. One end of the spiral stirring rod 21 extending outside the horizontal mixing cylinder 2 is provided with a driving part 22. An installation ring 23 is fixedly connected to the surface of the driving part 22. A pair of horizontal connecting bars 24 are fixedly connected between the installation ring 23 and one side of the horizontal mixing cylinder 2. A spiral stirring rod 11 is arranged in the vertical mixing cylinder 1 and is in linkage with the spiral stirring rod 21. A discharging mechanism 3 connected to an external spinning assembly is communicated with the horizontal mixing cylinder 2. The discharging mechanism 3 comprises a receiving pipe 31 communicated with the lower surface of the horizontal mixing cylinder 2. The other end of the receiving pipe 31 is communicated with a metering pump 32. A discharging pipe 33 is communicated with the metering pump 32.

[0027] During use, first, polyester raw materials and composite preparations are respectively added from the top port of the vertical mixing cylinder 1. Then, the driving part 22 using a servo motor is started to drive the spiral stirring rod 21 to rotate. While the spiral stirring rod 21 is rotating, it drives the spiral stirring rod 11 to preliminarily and evenly mix the polyester raw materials and composite preparations just added into the vertical mixing cylinder 1. Subsequently, the preliminarily mixed raw materials enter the interior of the horizontal mixing cylinder 2 and are secondarily mixed by the spiral stirring rod 21 to ensure the full and evenness of the raw materials, laying a solid foundation for the subsequent spinning process.

[0028] Finally, when the raw materials are mixed to an ideal state, the metering pump 32 is started. The metering pump 32 precisely extracts the mixed raw materials from the horizontal mixing cylinder 2 through the receiving pipe 31 and introduces them into the discharging pipe 33. Subsequently, these raw materials are transported to an external spinning assembly and finally form the required polyester fiber filaments through the spinning process.

[0029] It should be noted that the composite preparation in this technical solution is composed of various functional additives such as surfactants, bulking agents, micropore formers, crosslinking agents, softeners, antibacterial agents, and anti-ultraviolet agents. The synergistic effect of these additives enables the produced lightweight warm and quick-drying polyester fibers to have multiple characteristics such as lightweight, warmth retention, breathability, softness, antibacterial property, and anti-ultraviolet property.

[0030] Referring to Figure 4, Further, the vertical mixing cylinder 1 gradually narrows from the top end diameter to the bottom end diameter of the middle section. The end diameter of the vertical mixing cylinder 1 near the top of the middle section is the same as the bottom end diameter corresponding to the upper section of the vertical mixing cylinder 1, and the end diameter of the vertical mixing cylinder 1 near the bottom of the middle section is the same as the top end diameter corresponding to the lower section of the vertical mixing cylinder 1. With the unique design of the vertical mixing cylinder 1, its characteristic is that the diameter gradually decreases from the upper section to the lower section, and the top end diameter of the middle section matches the bottom end diameter corresponding to the upper section, while the bottom end diameter of the middle section is consistent with the top end diameter corresponding to the lower section. This gradual change in diameter cleverly extends the flow path of the raw materials in the vertical mixing cylinder 1; This design not only further increases the contact opportunities and mixing time between raw material particles, but also promotes the formation of eddy currents and shear forces, which can effectively break the agglomeration of raw material particles and ensure that the raw materials are more evenly and fully dispersed in the vertical mixing cylinder 1. Therefore, this design not only improves the mixing efficiency, but also optimizes the mixing quality, laying a solid foundation for the production of high-quality lightweight warm and quick-drying polyester fibers.

[0031] Refer to Figures 1 - 4 , In order to enable the second spiral stirring rod 11 to efficiently stir and mix the raw materials put into the vertical mixing cylinder 1 by means of the rotational force of the first spiral stirring rod 21, a material guiding block 13 is connected to the surface of the second spiral stirring rod 11 through a bearing. A plurality of connecting rods 14 distributed in a circular pattern are fixed between the surface of the material guiding block 13 and the inner wall of the vertical mixing cylinder 1. A sealing cavity 15 is provided in the material guiding block 13. One end of the second spiral stirring rod 11 located inside the sealing cavity 15 is fixedly connected with a first bevel gear 16. A transmission part 5 is provided between the surface of the first bevel gear 16 and the surface of the first spiral stirring rod 21. The transmission part 5 includes a connecting shaft 51 rotatably arranged between the material guiding block 13 and the vertical mixing cylinder 1. One end of the connecting shaft 51 is fixedly connected with a second bevel gear 52 connected to the surface of the first bevel gear 16. The other end of the connecting shaft 51 is fixedly connected with a first pulley 53. A matching transmission belt 54 is connected to the surface of the first pulley 53. The inner surface of the transmission belt 54 is connected with a matching second pulley 55, and the second pulley 55 is fixed on the surface of the first spiral stirring rod 21.

[0032] In the above technical solution, when the first spiral stirring rod 21 starts to rotate, it will drive the second pulley 55 fixed on the surface of the first spiral stirring rod 21 to rotate. The second pulley 55 transmits the power to the first pulley 53 through the transmission belt 54, thereby driving the connecting shaft 51 to rotate. The rotation of the connecting shaft 51 will also cause the second bevel gear 52 fixed at one end of it to rotate, thus driving the first bevel gear 16 meshing with the second bevel gear 52 to rotate. Finally, the rotation of the first bevel gear 16 will drive the second spiral stirring rod 11 to rotate in the vertical mixing cylinder 1 to realize the stirring and mixing of the raw materials. The advantage of this design is that it can simultaneously achieve primary mixing and secondary mixing, thereby significantly improving the mixing efficiency and mixing uniformity.

[0033] Referring to Figure 4 , further, the material guiding block 13 includes a first section 131, a second section 132, and a third section 133. The first section 131 corresponds to the upper part inside the vertical mixing cylinder 1, and the third section 133 corresponds to the middle part inside the vertical mixing cylinder 1. The top end diameter of the first section 131 gradually increases from the top to the bottom, which can guide the raw materials to spread around, avoiding the accumulation of raw materials in a certain area, so as to ensure that the raw materials can be evenly distributed in the vertical mixing cylinder 1. The top end diameter of the third section 133 gradually decreases from the top to the bottom. This structure helps the raw materials to be compressed and concentrated inside the middle part of the vertical mixing cylinder 1. When the raw materials flow downward, they will be gradually squeezed. This squeezing effect can enhance the interaction force between the materials, thereby further improving the mixing effect.

[0034] Through this segmented design of the material guiding block 13, not only the flow path of the raw materials is optimized, but also the spiral stirring rod two 11 can act on the raw materials more effectively during the stirring process.

[0035] Referring to Figure 1 , Figure 4 and Figures 6 - 8 , it also includes a top plate 4 connected to the top of the vertical mixing cylinder 1. A circular shell 41 is rotatably connected to the top plate 4. A vertical feeding pipe 42 inserted into the top end of the spiral stirring rod two 11 is fixed on the circular shell 41. A plurality of discharge ports 43 corresponding to the inside of the vertical mixing cylinder 1 and distributed in a circumferential manner are arranged on the surface of the vertical feeding pipe 42. An annular liquid collecting cavity 44 is formed between the surface of the vertical feeding pipe 42 and the inside of the circular shell 41. A liquid inlet pipe 45 is connected to the top of the annular liquid collecting cavity 44. A plurality of liquid outlet pipes 46 distributed in a circumferential manner and provided with control valves are connected to the bottom of the annular liquid collecting cavity 44. The liquid outlet end of the liquid outlet pipe 46 is inclined and corresponds to the front of the discharge port 43.

[0036] When the above technical solution is used, the composite preparation is pre-introduced into the annular liquid collecting cavity 44 from the liquid inlet pipe 45. Subsequently, the polyester raw material is put into the vertical feeding pipe 42. At the same time, the control valve on the surface of the liquid outlet pipe 46 is opened, so that the composite preparation in the annular liquid collecting cavity 44 can be preliminarily mixed with the raw materials flowing out of the discharge port 43 simultaneously in the direction close to the axis of the spiral stirring rod two 11. This feeding and mixing method is more efficient than the mixing efficiency when the composite preparation and the raw materials are added batch by batch or from different directions; Moreover, the liquid outlet end of the liquid outlet pipe 46 is inclined and corresponds to the front of the discharge port 43. Therefore, when the composite preparation is ejected, it can also impact the raw materials introduced from the bottom end of the vertical feeding pipe 42. This impact effect can not only enhance the mixing effect, but also avoid the blockage problem of the raw materials at the discharge position of the bottom wall of the vertical feeding pipe 42.

[0037] Referring to Figure 8, Further, a hemispherical block 47 is fixedly connected to the bottom wall of the vertical feeding pipe 42, and the top of the hemispherical block 47 is lower than the top port of the discharge port 43. With this design, it can effectively prevent the raw materials from accumulating or forming dead corners at the bottom of the vertical feeding pipe 42. Since the shape of the hemispherical block 47 is hemispherical, when the raw materials fall from the vertical feeding pipe 42, they will smoothly slide along the surface of the hemispherical block 47, thus avoiding the problem of raw material accumulation at the bottom of the vertical feeding pipe 42. Secondly, the top of the hemispherical block 47 is lower than the top port of the discharge port 43, which means that the raw materials will be subjected to a certain guiding effect after contacting the hemispherical block 47 and are more easily guided to the position of the discharge port 43. This can not only improve the outflow efficiency of the raw materials but also ensure that the raw materials can be evenly distributed in the vertical mixing cylinder 1.

[0038] Refer to Figure 5 , Further, a square groove 48 is opened at the bottom end of the vertical feeding pipe 42, and a square block 12 that fits closely with the inner wall of the square groove 48 is fixedly connected to the top end of the second spiral stirring rod 11. This unique design ensures that when the second spiral stirring rod 11 rotates, it can effectively drive the vertical feeding pipe 42 and the circular shell 41 connected thereto to rotate together through the close cooperation between the square block 12 and the square groove 48, so that the raw materials and the composite preparation can be more evenly distributed inside the vertical mixing cylinder 1 in a rotating manner. This rotating distribution method not only improves the mixing uniformity but also forms a good synergistic effect with the stirring action of the second spiral stirring rod 11, further promoting the full mixing of the raw materials and the composite preparation, thus achieving a better mixing effect.

[0039] In this application, the high-efficiency primary and secondary mixing of polyester raw materials and composite preparations is realized, significantly improving the mixing uniformity and laying a solid foundation for the subsequent spinning process. Compared with the traditional static feeding method, it can further promote the mixing uniformity effect. By using a composite preparation containing a variety of functional additives and acting synergistically in the production process of polyester fibers, the finally produced polyester fibers have multiple characteristics such as lightweight, warm, breathable, soft, antibacterial, and anti-ultraviolet, improving the comprehensive performance and market competitiveness of the product.

[0040] Refer to Figures 9 - 16 , among which, the test reports and sample schematic diagrams of lightweight warm and quick-drying polyester fibers in terms of heat preservation rate and moisture absorption and quick drying are introduced. Specifically, the test reports of the lightweight warm and quick-drying polyester fibers prepared by the above preparation method in terms of moisture absorption and quick drying, zero-pressure lightweight, and fluffy warmth are shown in Tables 1, 2, 3, and 4 below: Table 1 Table 2 Table 3 Table 4 The above embodiments only illustrate several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made. These are all equivalent modifications and evolutions based on the substantial technology of the present invention to the above embodiments, and all of these fall within the protection scope of the present invention.
