[0002] Polypropylene filament, full name polypropylene filament, is a filament fiber made of polypropylene through spinning process. It has the advantages of light weight, high strength, chemical corrosion resistance, etc., and sportswear, underwear, socks, etc. made of polypropylene filament have good air permeability and moisture absorption, making them more comfortable to wear, and have hydrophilic and skin-friendly effects, and will not cause irritation to human skin.

[0003] The production of polypropylene filaments usually uses polypropylene as the main raw material, and then heats the polypropylene to a molten state through the melt spinning method, and extrudes it through the spinneret to form filaments. In the production process, precise control of parameters such as temperature, pressure, and spinning speed is crucial, which directly affects the quality and performance of polypropylene filaments. In addition, after production, it needs to be cooled to quickly shape it to avoid distortion or deformation.

However, in the prior art, no temperature difference regulating device is provided in the water tank, so that the water temperature in the water tank tends to be consistent, which causes the polypropylene filaments to directly contact the water flow with a lower temperature, thereby easily causing internal stress in the polypropylene filaments, thereby affecting the precision of the product, making the polypropylene filaments easily deformed or broken, affecting the quality of the product, and causing unnecessary troubles for users.

A drain pipe is installed on the side wall of the collecting chamber, and the other end of the drain pipe is connected to the storage water tank to facilitate the water to flow back into the storage water tank.

[0022] In one or more embodiments of the present invention, the dehumidification cylinder is provided with a rotating support plate for supporting a plurality of fine brushes and driving the plurality of fine brushes to rotate, so as to facilitate shaking the polypropylene filaments and splashing the water droplets on the polypropylene filaments, and the rotating support plate is provided with a plurality of evenly distributed driven racks for conveniently driving the rotating support plate to rotate;

[0023] A plurality of fine brushes are fixed on the rotating support disc, which are used to hit the polypropylene filaments to make the polypropylene filaments shake, so as to shake and splash the water droplets on the polypropylene filaments, thereby improving the dehumidification effect of the polypropylene filaments and facilitating subsequent drying;

[0024] A rotating motor is arranged below the dehumidifier cylinder to drive the driving shaft and the driving gear to rotate, thereby providing power for the rotating support plate to drive the rotation of multiple fine brushes. A driving shaft is installed on the rotating motor to support the driving gear and drive the driving gear to rotate. A driving gear meshing with multiple driven racks is installed on the other end of the driving shaft to drive the rotating support plate to rotate, thereby playing a transmission role.

[0026] In one or more embodiments of the present invention, a sliding groove is excavated in the supporting chassis, and a sliding motor is installed on the side wall of the sliding groove, which is used to drive the driving screw to rotate and provide power for the sliding of the winding sleeve. A sliding support block is arranged in the sliding groove, which is used to support the supporting bottom block and the supporting chassis and has the function of driving them to move;

[0027] The sliding support block is threadedly connected with a driving screw, which is used to drive the sliding support block to slide after rotating, so as to enable the supporting chassis to move. The driving screw is fixedly connected to the output end of the sliding motor, and a supporting bottom block is fixedly connected between the sliding support block and the supporting chassis. A pair of limiting bars are fixed on the winding shaft rod, which are used to limit the winding sleeve, so that the winding shaft rod can drive the winding sleeve to rotate.

[0028] A method for manufacturing a hydrophilic and skin-friendly polypropylene filament production device comprises the following steps:

[0029] S1, first pass the produced polypropylene filament through the inlet hole, then pass around a pair of guide components and then pass through the outlet hole, then pass the polypropylene filament through the dehumidification cylinder and the moisture-absorbing cotton, and finally buckle it on the winding sleeve, then start the winding motor and the sliding motor, and drive the winding shaft and the winding sleeve to rotate through the winding motor to realize the winding of the polypropylene filament, and after the sliding motor starts the forward and reverse rotation, it will drive the sliding support block to move back and forth, so that the winding sleeve can evenly wind the polypropylene filament;

[0030] S2, then start the air supply pump, the water pump and the rotating motor, pump out the cooling water in the storage water tank through the water pump, and transport it to the graded cooling tank, and because the widths of the third cooling groove, the second cooling groove and the first cooling groove increase in sequence, the flow rate of the cooling water in the third cooling groove, the second cooling groove and the first cooling groove is slowed down in sequence;

[0031] S3, and the cooling water will be heated by the heating cylinder after entering the second cooling tank, so that the temperature of the cooling water increases, and the cooling water in the first cooling tank will be further heated, so by slowing down the flow rate and heating the cooling water, the temperatures in the third cooling tank, the second cooling tank and the first cooling tank are gradually increased, and the polypropylene filaments will first pass through the third cooling tank, then the second cooling tank, and finally the first cooling tank, so the polypropylene filaments will be gradually cooled and will not directly contact the cooling water with a lower temperature, thereby reducing the internal stress of the polypropylene filaments;

[0032] S4. Moreover, as the amount of cooling water entering the graded cooling box gradually increases, the cooling water will be discharged into the storage water tank through the reflux straight pipe, so that the cooling water can be recycled, and heat can be dissipated and cooled during the circulation process for reuse. In addition, since the horizontal height of one end of the reflux straight pipe close to the graded cooling box is located between the upper guide roller and the lower guide roller, the polypropylene filaments will completely pass through the third cooling groove, the second cooling groove and the first cooling groove before being moved out of the box outlet, so that the polypropylene filaments are fully cooled and shaped.

[0033] S5, then the polypropylene filaments return to the dehumidification cylinder, and will first be absorbed by the moisture-absorbing cotton, so that the moisture on the surface of the polypropylene filaments is initially absorbed, and the start of the rotating motor will drive the driving gear to rotate, and then drive the rotating support plate and multiple fine brushes, and the multiple fine brushes will hit the polypropylene filaments again, so that the water droplets on the surface of the polypropylene filaments are splashed out;

[0034] S6. When the air supply pump is started, external gas will be drawn in, and then it will be heated in the heating cylinder through multiple connecting air pipes, and then transported to the fixed frame, and finally transported to the transporting air cavity through the transporting air pipe, and then blown to the polypropylene filaments through multiple nozzles, so that the polypropylene filaments can be dried quickly, so that no moisture will remain on the surface of the rolled polypropylene filaments.

[0035] Compared with the prior art, the present invention, through the setting of corresponding mechanisms, enables the polypropylene filaments to be cooled step by step during cooling and shaping, and will not directly contact the water flow with a lower temperature, thereby avoiding the generation of internal stress in the polypropylene filaments, reducing the probability of deformation or breakage of the polypropylene filaments, improving the quality of the products, and reducing unnecessary troubles for users.

[0053] like Figure 1 to Figure 2 As shown, an air supply pump 102 is installed under the support table 1 for inhaling gas, thereby facilitating conditions for subsequent wind drying. An air supply pipe is fixedly connected to the air supply pump 102, and a dispersion chamber 101 is opened in the support table 1. The dispersion chamber 101 is connected to the air supply pipe, so that the gas can be dispersed into multiple connecting air pipes 215.

[0054] Among them, multiple supporting legs 103 are arranged under the supporting platform 1 to support the supporting platform 1, so as to ensure the stability of the supporting platform 1 and prevent the supporting platform 1 from shaking and tilting, thereby avoiding the breakage of the polypropylene filaments and facilitating the cooling and collection of the polypropylene filaments.

The graded cooling box 201 includes a first cooling trough 202, a second cooling trough 203 and a third cooling trough 204. The temperature of cooling water in the first cooling trough 202, the second cooling trough 203 and the third cooling trough 204 is gradually reduced, so that the polypropylene filaments can be gradually cooled and shaped, thereby avoiding the internal stress caused by rapid cooling.

[0056] like Figures 1 to 8 As shown, a water pump 218 is provided below the support plate 1, which is used to extract the cooling water in the storage water tank 208, so that the cooling water in the graded cooling box 201 can circulate, and prevent the cooling water temperature in the graded cooling box 201 from continuously rising and becoming uniform. The water pump 218 is fixedly connected with a liquid extraction pipe 219 and a liquid delivery pipe 205, both of which are used to deliver cooling water, and the other end of the liquid delivery pipe 205 is inserted into the graded cooling box 201.

A plurality of reflux straight pipes 209 are fixedly connected between the storage water tank 208 and the graded cooling box 201, so that the cooling water in the graded cooling box 201 can flow back to the storage water tank 208, so that the temperature of the cooling water can be reduced, and the cooling water temperature in the graded cooling box 201 is prevented from being too high.

[0058] like Figures 1 to 7 As shown, an auxiliary roller 211, a pair of shielding baffles 210 and a guide assembly 212 are installed in the graded cooling box 201. The auxiliary roller 211 is used to assist the movement of the polypropylene filaments to prevent the polypropylene filaments from getting stuck. The shielding baffles 210 are used to initially block the water from flowing into the second cooling trough 203 or the first cooling trough 202, so that the polypropylene filaments can be submerged in the cooling water before the cooling water flows into the second cooling trough 203 or the first cooling trough 202, thereby improving the cooling effect of the polypropylene filaments. The guide assembly 212 is used to guide the polypropylene filaments so that the polypropylene filaments can be immersed in the cooling water.

[0059] Specifically, a pair of guide assemblies 212 each include an upper guide roller 2121 and a lower guide roller 2122, and the reflux straight pipe 209 is located between the upper guide roller 2121 and the lower guide roller 2122 at a horizontal height at one end close to the graded cooling box 201, so that the polypropylene filaments can safely pass through the first cooling trough 202, the second cooling trough 203 and the third cooling trough 204, and the polypropylene filaments can be completely immersed in the cooling water, so that the polypropylene filaments can be fully cooled and shaped.

[0076] S1, first pass the produced polypropylene filaments through the box inlet hole 206, then pass around a pair of guide components 212 and pass through the box outlet hole 207, then pass the polypropylene filaments through the dehumidification cylinder 301 and the moisture-absorbing cotton 304, and finally buckle them on the winding sleeve 403, then start the winding motor 404 and the sliding motor 406, and drive the winding shaft 402 and the winding sleeve 403 to rotate through the winding motor 404 to achieve the winding of the polypropylene filaments, and after the sliding motor 406 starts the forward and reverse rotation, it will drive the sliding support block 407 to move back and forth, so that the winding sleeve 403 can evenly wind the polypropylene filaments;

[0077] S2, then start the air supply pump 102, the water pump 218 and the rotating motor 313, pump out the cooling water in the storage water tank 208 through the water pump 218, and transport it to the staged cooling tank 201, and because the widths of the third cooling groove 204, the second cooling groove 203 and the first cooling groove 202 increase in sequence, the flow rate of the cooling water in the third cooling groove 204, the second cooling groove 203 and the first cooling groove 202 is slowed down in sequence;

[0078] S3, and the cooling water will be heated by the heating cylinder 214 after entering the second cooling tank 203, so that the temperature of the cooling water increases, and the cooling water in the first cooling tank 202 will be further heated, so by slowing down the flow rate and heating the cooling water, the temperatures in the third cooling tank 204, the second cooling tank 203 and the first cooling tank 202 are gradually increased, and the polypropylene filaments will first pass through the third cooling tank 204, then pass through the second cooling tank 203, and finally pass through the first cooling tank 202, so the polypropylene filaments will be gradually cooled and will not directly contact the cooling water with a lower temperature, thereby reducing the internal stress of the polypropylene filaments;

[0079] S4. Moreover, as the amount of cooling water entering the graded cooling box 201 gradually increases, the cooling water will be discharged into the storage water tank 208 through the return straight pipe 209, so that the cooling water can be recycled, and heat can be dissipated and cooled during the circulation process for reuse. In addition, since the end of the return straight pipe 209 close to the graded cooling box 201 is located between the upper guide roller 2121 and the lower guide roller 2122 at a horizontal height, the polypropylene filaments will completely pass through the third cooling groove 204, the second cooling groove 203 and the first cooling groove 202 before being moved out of the box outlet 207, so that the polypropylene filaments are fully cooled and shaped.

[0080] S5, the polypropylene filaments then return to the dehumidification cylinder 301, and will first be absorbed by the moisture-absorbing cotton 304, so that the moisture on the surface of the polypropylene filaments is initially absorbed, and the start of the rotating motor 313 will drive the driving gear 315 to rotate, and then drive the rotating support plate 310 and the multiple fine brushes 312, and the multiple fine brushes 312 will hit the polypropylene filaments again, so that the water droplets on the surface of the polypropylene filaments are splashed out;

[0081] S6. When the air supply pump 102 is started, external gas will be drawn in, and then the gas will be heated in the heating cylinder 214 through multiple connecting air pipes 215, and then transported to the fixed frame 216, and finally transported to the transporting air cavity 302 through the transporting air pipe 217, and then blown to the polypropylene filaments through multiple nozzles 303, so that the polypropylene filaments can be quickly dried, so that no moisture will remain on the surface of the rolled polypropylene filaments.
