Technical Field

[0001] The present invention relates to the technical field of fiber production, and specifically to a manufacturing device and a manufacturing method for a two-component colored composite fiber. Background Art

[0002] Composite fiber is a type of fiber and is a term for man-made fiber varieties. There are two or more non-mixed polymer fibers on the cross-section of the same fiber, and this kind of fiber is called composite fiber. Generally, after the composite fiber is melted and extruded, it needs to be cooled before being wound up. For the existing cooling method, the composite fiber is generally passed straight through a water tank filled with water for cooling. The length required for the water tank is long, resulting in a large occupied space and being unfavorable for the effective utilization of the site. Therefore, the applicant has developed a new technical solution during the actual production process to solve the above technical problems. Summary of the Invention

[0005] By adopting the above technical solutions, one end of the composite fiber is wound through the cooling box in an S-shaped trajectory through the guiding mechanism. At this time, because the composite fiber winds through the cooling box in an S-shaped trajectory, the length of the water storage box and the cooling box can be shortened, thereby reducing the floor area occupied by the water storage box and the cooling box. When pulling the composite fiber, through the pumping mechanism, the water in the water storage box is pumped to the guiding mechanism to cool the composite fiber on the guiding mechanism.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: A manufacturing device for a two-component colored composite fiber, as Figure 1 and Figure 3 , includes a cooling box 1, a water storage box 2, and a guiding mechanism. The water storage box 2 is horizontally arranged at the bottom of the cooling box 1 inside the cooling box 1, and the guiding mechanism is arranged inside the cooling box 1 and above the water storage box 2. The guiding mechanism is used for allowing the composite fiber 17 to wind through the cooling box 1 in an S-shaped trajectory; It further includes a water pumping mechanism, which is arranged on the cooling box 1, and the water pumping mechanism is used for pumping the water in the water storage box 2 to the guiding mechanism to cool the composite fiber 17 on the guiding mechanism; A cooling mechanism, which is arranged on the cooling box 1, and the cooling mechanism is used for cooling the water passing through the guiding mechanism and discharging the cooled water into the water storage box 2.

[0021] As Figure 1 and Figure 3, one end of the composite fiber 17 is spirally wound through the cooling box 1 along an S-shaped trajectory by a guiding mechanism. At this time, since the composite fiber 17 is spirally wound through the cooling box 1 along an S-shaped trajectory, the length of the water storage box 2 and the cooling box 1 can be shortened, thereby reducing the floor area occupied by the water storage box 2 and the cooling box 1. When pulling the composite fiber 17, through the water pumping mechanism, the water in the water storage box 2 is pumped to the guiding mechanism to cool the composite fiber 17 on the guiding mechanism. At the same time, through the cooling mechanism, the water passing through the guiding mechanism is cooled and the cooled water is discharged into the water storage box 2, so that the water can be recycled and the waste of water resources is reduced.

[0022] As Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 , the guiding mechanism includes several boxes 3, and a diversion pipe 4 is inclined at the bottom end of each box 3. The top end of the diversion pipe 4 extends into the box 3. Each box 3 is installed in the cooling box 1, and each box 3 is spaced from left to right along the length direction of the cooling box 1. Each diversion pipe 4 is parallel to each other. A first guide roller 6 is installed below the right side of each diversion pipe 4 through a first mounting frame 5, and a second guide roller 8 is installed above the left side of each diversion pipe 4 through a second mounting frame 7. The first guide roller 6 and the second guide roller 8 are staggered, and the second guide roller 8 is located in the box 3. The number of boxes 3 is three, and the three boxes 3 are the first box 3, the second box 3, and the third box 3 from left to right. Third guide rollers 10 are installed above the left sides of the tops of the second box 3 and the third box 3 through a third mounting frame 9. The bottom of the box in the first box 3 is rotatably connected to a guide wheel 12 through a rotating shaft. The guide wheel 12 is located in the first box 3 and on the left side of the second guide roller 8. Circular holes 13 penetrating the box 3 are opened on the side walls of the three boxes 3. An opening 14 corresponding to the circular hole 13 is provided on the right side of the cooling box 1. Guide rollers 16 are installed above the right sides of the three boxes 3 through a U-shaped connecting frame 15, and the guide rollers 16 are located above the diversion pipes 4. The water pumping mechanism is used to pump the water in the water storage box 2 into the three diversion pipes 4. One end of the composite fiber 17 enters the first box 3 from right to left through the opening 14 and the circular holes 13 on the three boxes 3 in sequence. At this time, the composite fiber 17 in the box 3 is in a horizontal state. One end of the composite fiber 17 located in the first box 3 passes through the guide wheel 12, the second guide roller 8, the diversion pipe 4, and the first guide roller 6 on the first box 3 in sequence, and then passes through the third guide roller 10, the second guide roller 8, the diversion pipe 4, and the first guide roller 6 on the second box 3 in sequence, and then passes through the third guide roller 10, the second guide roller 8, the diversion pipe 4, and the first guide roller 6 on the third box 3 in sequence, and is led out of the cooling box 1 from the guide roller 16 on the third box 3. At this time, the composite fiber 17 located below the three boxes 3 is in an S shape.

[0023] As Figure 5 andFigure 6 At the bottom ends inside the three boxes 3, support rollers 19 are installed through fixing frames 18. The support rollers 19 are located on one side of the diversion pipe 4 and are arranged side by side with the second guide rollers 8. The support rollers 19 correspond to the circular holes 13, and the top ends of the support rollers 19 are in contact with the bottom ends of the composite fibers 17 that are horizontal after passing through the circular holes 13. The purpose of this setting is to support the composite fibers 17 that are horizontal after passing through the circular holes 13 through the support rollers 19, which is simple and convenient to use.

[0024] Such as Figure 2 and Figure 3 and Figure 4 and Figure 6 The water pumping mechanism includes a water distribution pipe 20 and three connecting pipes 21. The three connecting pipes 21 are all connected to the water distribution pipe 20, and the ends of the three connecting pipes 21 far from the water distribution pipe 20 are respectively communicated with the lower sides of one sides of the three diversion pipes 4. The water distribution pipe 20 is installed on the front side of the outer wall of the cooling box 1, and a connecting pipe 22 is provided on the water distribution pipe 20. The end of the connecting pipe 22 far from the water distribution pipe 20 is communicated with the water storage box 2. A water pump 23 is provided on the connecting pipe 22. The bottom ends of the three diversion pipes 4 are all communicated with rectangular funnels 24. One end of the composite fiber 17 passes through the funnels 24. The water output of the funnels 24 is F, and the water input of the connecting pipes 21 is F1, and F1 is greater than F. There is a gap between the rear sides of the three boxes 3 and the box wall of the cooling box 1, and side grooves 25 are provided above the rear sides of the three boxes 3, and the side grooves 25 are communicated with the top ends of the boxes 3.

[0025] Such as Figure 2 and Figure 3 and Figure 4 and Figure 6 When the water pump 23 is turned on, the water in the water storage box 2 will sequentially enter the three connecting pipes 21 through the connecting pipe 22 and the water distribution pipe 20, and then enter the three diversion pipes 4 from the three connecting pipes 21 respectively. At this time, because F1 is greater than F, the diversion pipes 4 will be filled with water. When the diversion pipes 4 are filled with water, the water in the diversion pipes 4 will overflow into the boxes 3 communicated with the diversion pipes 4. As the water pump 23 continues to work, the water level in the boxes 3 will gradually rise until the water level rises to the side grooves 25. At this time, the water in the boxes 3 will flow out from the side grooves 25, and the water flowing out from the side grooves 25 will flow back to the water storage box 2 under the influence of gravity. In the above process, the composite fibers 17 passing through the diversion pipes 4 can be cooled by the water in the diversion pipes 4. Without filling the cooling box 1 with water, the length of the water storage box 2 and the cooling box 1 is shortened, saving water resources. Moreover, the three diversion pipes 4 can cool the composite fibers 17 three times. When the water level in the boxes 3 rises to the side grooves 25, the guide wheels 12 will be located in the water in the boxes 3. At this time, through the water in the boxes 3, the composite fibers 17 passing through the boxes 3 can be pre-cooled, which is simple and convenient to use.

[0026] Such asFigure 2 , three communication grooves 26 are formed at one end of the cooling box 1 close to the water distribution pipe 20. The three communication grooves 26 respectively correspond to the three first guide rollers 6, and the three communication grooves 26 are all communicated with the top end of the cooling box 1. The purpose of this setting is that after the composite fiber 17 passes through the diversion pipe 4, the composite fiber 17 can bypass the first guide roller 6 through the communication groove 26, which is simple and convenient to use.

[0027] Such as Figure 2 and Figure 3 and Figure 4 and Figure 6 and Figure 7 , the cooling mechanism includes a partition 27 arranged at the top end of the water storage box 2. The top end of the partition 27 is in contact with the bottom ends of the three boxes 3. The partition 27 divides the inside of the cooling box 1 into a front area 28 and a rear area 29. The diversion pipes 4 on the boxes 3 are located in the front area 28. One end of each of the three boxes 3 close to the side groove 25 is provided with a communication box 30 communicated with the side groove 25, and the opening of the communication box 30 faces the side groove 25. The communication box 30 is located above the rear area 29, and a plurality of water dripping holes 31 are formed at the bottom end of the communication box 30. An L-shaped water guide box 32 is arranged at the top end of the water storage box 2, and the water guide box 32 is located in the front area 28. The water guide box 32 is located below the three funnels 24, and the opening of the water guide box 32 faces upward. The shorter end of the water guide box 32 passes through the partition 27 and is located in the rear area 29. A drain port 33 communicated with the water guide box 32 is formed at one end of the outer wall of the water guide box 32 located in the rear area 29. The purpose of this setting is that the water flowing out of the side groove 25 enters the communication box 30, and then drips downward from the respective water dripping holes 31 of the communication box 30. After passing through the rear area 29, it drips into the water storage box 2. During the downward dripping process, the water can be cooled by heat dissipation. A part of the water in the diversion pipe 4 is discharged from the funnel 24, and the discharged water enters the water guide box 32, and then flows along the water guide box 32 to the rear area 29 and is discharged into the water storage box 2 from the drain port 33. During the process of the water flowing along the water guide box 32, the water in the water guide box 32 can be cooled by heat dissipation, which is simple and convenient to use.

[0028] Such as Figure 2 and Figure 6 and Figure 7, a blowing mechanism for blowing air into the rear area 29 is provided on the cooling box 1. The blowing mechanism includes a dispersion box 34 and a number of heat conduction tubes 35 horizontally arranged on the partition plate 27. The dispersion box 34 is horizontally arranged on the front side of the cooling box 1, and the box opening of the dispersion box 34 faces the cooling box 1. Each heat conduction tube 35 is located in the front area 28. The heat conduction tubes 35 are spaced apart along the length direction of the partition plate 27, and one end of each heat conduction tube 35 away from the partition plate 27 passes through the box wall of the water guide box 32 and communicates with the dispersion box 34. An air extraction pipe 36 is provided on one side of the outer wall of the dispersion box 34, and an air extraction fan 37 is provided on the air extraction pipe 36. A baffle 38 located in the water storage box 2 is provided at the bottom end of the partition plate 27, and the bottom end of the baffle 38 is below the water surface in the water storage box 2. The air extraction fan 37 is installed on the outer wall of the cooling box 1.

[0029] As Figure 2 and Figure 6 and Figure 7 , during the process of water dripping downward from each water dripping hole 31 of the communication box 30 into the rear area 29, by turning on the air extraction fan 37, the outside air is blown into the dispersion box 34 from the air extraction pipe 36, and then blown into the rear area 29 from the dispersion box 34 through each heat conduction tube 35. At this time, since the bottom end of the baffle 38 is below the water surface in the water storage box 2, the air blown into the rear area 29 will flow upward. At this time, the fluidity of the air in the rear area 29 can be increased, so as to facilitate the cooling of the water dripping downward from each water dripping hole 31. When the water in the water guide box 32 contacts the outer wall of the heat conduction tube 35 and the air passes through each heat conduction tube 35 and is blown into the rear area 29, the water in the water guide box 32 can be cooled by the heat conduction tube 35 and the air flowing in the heat conduction tube 35, improving the heat dissipation and cooling effect of the water.

[0030] As Figure 1 and Figure 2 , a rectangular frame 39 is provided on the cooling box 1. The air extraction fan 37, the water extraction pump 23, the dispersion box 34, and the water distribution pipe 20 are all located in the rectangular frame 39. Two cabinet doors 40 are hinged on one side of the rectangular frame 39 away from the cooling box 1. An air inlet 41 is provided on the cabinet door 40 close to the air extraction fan 37. The purpose of this setting is to protect the air extraction fan 37 and the water extraction pump 23 through the rectangular frame 39 and the two cabinet doors 40, reducing the occurrence of damage caused by collision with external objects. When the air extraction fan 37 works, the outside air enters the rectangular frame 39 from the air inlet 41 and then enters the air extraction pipe 36 from the air extraction fan 37, which is simple and convenient to use.

[0031] The usage process of this device is as follows: First step, one end of the composite fiber 17 passes through the opening 14 and the circular holes 13 on the three boxes 3 from right to left in sequence, so that one end of the composite fiber 17 enters the first box 3. At this time, the composite fiber 17 in the box 3 is in a horizontal state. Then, one end of the composite fiber 17 in the first box 3 passes through the guide wheel 12 and the second guide roller 8 on the first box 3 and is placed into the diversion tube 4 on the first box 3.

[0032] Second step, turn on the water pump 23 to make water enter the three boxes 3, and then the water pump 23 stops working. At this time, the water in the box 3 will be discharged from the funnel 24 through the diversion tube 4. During the process of the water being discharged from the funnel 24, gradually place the composite fiber 17 into the diversion tube 4 until the length of the composite fiber 17 placed in the diversion tube 4 is greater than the length of the diversion tube 4. At this time, the water discharged from the funnel 24 through the diversion tube 4 can bring out one end of the composite fiber 17 from the diversion tube 4. After one end of the composite fiber 17 is discharged from the funnel 24 of the diversion tube 4 on the first box 3, bypass one end of the composite fiber 17 around the first guide roller 6, and then bypass the third guide roller 10 and the second guide roller 8 on the second box 3 in sequence and place it into the diversion tube 4 on the second box 3. Then turn on the water pump 23 to make water enter the three boxes 3, and then the water pump 23 stops working. And so on, one end of the composite fiber 17 can pass through the guide wheel 12, the second guide roller 8, the diversion tube 4, and the first guide roller 6 on the first box 3 in sequence, and then pass through the third guide roller 10, the second guide roller 8, the diversion tube 4, and the first guide roller 6 on the second box 3 in sequence, and then pass through the third guide roller 10, the second guide roller 8, the diversion tube 4, and the first guide roller 6 on the third box 3 in sequence, and is led out of the cooling box 1 from the guide roller 16 on the third box 3. At this time, the composite fiber 17 under the three boxes 3 is in an S shape, and the composite fiber 17 led out of the cooling box 1 from the guide roller 16 on the third box 3 passes above the guide rollers 16 on the first box 3 and the second box 3. At this time, the composite fiber 17 led out of the cooling box 1 can be supported by the guide rollers 16 on the first box 3 and the second box 3.

[0033] In the third step, after one end of the composite fiber 17 is led out of the cooling box 1 from the guide roller 16 on the third box body 3, the water pump 23 starts to work continuously. When pulling and conveying the composite fiber 17, the water in the diversion pipe 4 can cool the composite fiber 17 passing through the diversion pipe 4. At this time, since F1 is greater than F, when the water pump 23 works continuously, the water in the diversion pipe 4 will overflow into the box body 3 communicating with the diversion pipe 4. With the continuous operation of the water pump 23, the water level in the box body 3 will gradually rise until the water level rises to the side groove 25. At this time, the water in the box body 3 will flow from the side groove 25 to the communicating box 30, and then drip downward from each water dripping hole 31 of the communicating box 30 into the storage box communicating with the rear area 29. During the downward dripping process, the water can be cooled by heat dissipation. A part of the water in the diversion pipe 4 is discharged from the funnel 24, and the discharged water enters the water guide box 32, and then flows along the water guide box 32 to the rear area 29 and is discharged from the drain port 33 to the water storage box 2. During the process of the water flowing along the water guide box 32, the water in the water guide box 32 can be cooled by heat dissipation; When the water level in the box body 3 rises to the side groove 25, the guide wheel 12 is located in the water in the box body 3. At this time, through the water in the box body 3, the composite fiber 17 passing through the box body 3 can be pre-cooled.

[0034] In the fourth step, during the process of the water dripping downward from each water dripping hole 31 of the communicating box 30, the exhaust fan 37 is turned on, and the outside air is blown into the dispersion box 34 from the exhaust pipe 36, and then blown into the rear area 29 from the dispersion box 34 through each heat conduction pipe 35. At this time, since the bottom end of the baffle 38 is located below the water surface in the water storage box 2, the air blown into the rear area 29 will flow upward, increasing the air fluidity in the rear area 29, so as to facilitate the cooling of the water dripping downward from each water dripping hole 31 under the influence of gravity. The water flowing in the water guide box 32 contacts the outer wall of the heat conduction pipe 35. When the air passes through each heat conduction pipe 35 and is blown into the rear area 29, through the heat conduction pipe 35 and the air flowing in the heat conduction pipe 35, the water flowing in the water guide box 32 can be cooled, improving the heat dissipation and cooling effect of the water.

[0035] In the second step, after one end of the composite fiber 17 is discharged from the funnel 24 of the diversion pipe 4 on the first box body 3, one end of the composite fiber 17 is bypassed around the first guide roller 6 on the first box body 3 and led out of the cooling box 1 from the guide roller 16 on the first box body 3. Or, after one end of the composite fiber 17 is discharged from the funnel 24 of the diversion pipe 4 on the second box body 3, one end of the composite fiber 17 is bypassed around the first guide roller 6 on the second box body 3 and led out of the cooling box 1 from the guide roller 16 on the second box body 3. Through the above process, the residence time of the composite fiber 17 in the cooling box 1 can be adjusted, so as to adjust the cooling time of the composite fiber 17 to adapt to different composite fibers 17, which is simple and convenient to use.

[0036] Example 2: A manufacturing method of a two-component colored composite fiber. The two-component colored composite fiber has a skin-core structure, that is, when viewed from the cross-section, it is two concentric circles: an outer skin layer and an inner core layer located within the outer skin layer. The outer skin layer is a polyethylene layer, and the inner core layer is a polypropylene layer. The blue masterbatch is added to the inner core layer by an automatic masterbatch feeder in a certain proportion, and the fiber is colored by light transmission according to the light transmittance of the outer skin layer material. After the two-component colored composite fiber is extruded, it is cooled by the above manufacturing equipment and then wound up.

[0037] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
