Description

Technical Field

[0001] The invention relates to the technical field of PVDF hollow fiber membrane spinning and forming, in particular to PVDF hollow fiber membrane spinning and forming equipment. Background Art

[0002] PVDF hollow fiber membrane spinning equipment is a kind of equipment specially used for producing PVDF (polyvinylidene fluoride) hollow fiber membrane. PVDF is a highly engineered fluorinated polymer with excellent mechanical properties, chemical stability, biocompatibility, high dielectric strength, resistance to UV radiation degradation, and good piezoelectric and pyroelectric properties.

[0003] The conventional PVDF hollow fiber membrane spinning forming device generally extrude the spinning raw materials by an extrusion spinneret to form the spinning. After the spinning is formed, the spinning is cooled by water cooling or air cooling. After the spinning is cooled and formed, the spinning is directly collected by a spinning collection device. However, for the device that cools the spinning by water cooling, a large amount of water will remain on the spinning after water cooling. The spinning is directly collected without cleaning the excess water. The excess water on the spinning will affect the compactness of the spinning collection during collection, and finally cause the spinning to be loosely wound on the collection shaft. During use, the spinning may be entangled with each other, affecting normal use.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8 As shown, a PVDF hollow fiber membrane spinning and forming equipment comprises a water tank 1, four supporting legs 2 are fixedly installed on the top of the water tank 1, and a stirring box 3 is fixedly connected to the top of the four supporting legs 2;

[0034] Also included is a collecting mechanism for collecting the PVDF hollow fiber membrane spinning;

[0035] The collecting mechanism includes a second motor 72, which is fixedly installed on one side of the water tank 1, and a second bracket 64 is fixedly installed on the bottom wall of the inner surface of the water tank 1, and a second material guide column 646 and a first material guide column 642 are rotatably installed in the middle of the second bracket 64, and the output shaft of the second motor 72 is fixedly connected to the second material guide column 646, and the output shaft of the second motor 72 is fixedly connected to the first pulley 73, and a belt 75 is wound around the outer surface of the first pulley 73, and the other end of the belt 75 is wound around the second pulley 751, and a third connecting rod 77 is fixedly connected to one side of the second pulley 751, and a reciprocating screw rod 771 is fixedly connected to one end of the third connecting rod 77, and an I-shaped collecting shaft 78 is threadedly connected to the outer surface of the reciprocating screw rod 771.

[0036] After the spinning is produced, the spinning must first be cooled. After the spinning is cooled by water cooling, in addition to a part of the water that needs to be retained by the spinning itself, a large amount of excess water will remain on the spinning surface. When the spinning is collected, the excess water will affect the compactness of the spinning collection, and the spinning is prone to entanglement during use.

[0037] When in use, the spinning raw material is stirred in the stirring box 3 and then processed into spinning. The newly produced spinning is cooled by the water in the water tank 1. The second guide column 646 rotates under the drive of the second motor 72. The spinning is located between the first guide column 642 and the second guide column 646. When the second guide column 646 rotates, it will cooperate with the first guide column 642 to move the spinning. The first guide column 642 and the second guide column 646 sandwich the spinning in the middle, which can remove excess moisture on the outer surface of the spinning. When the second motor 72 rotates, the second pulley 751 is rotated by the belt 75, and the second pulley 751 is rotated with the third connecting rod 77. The reciprocating wire rod 771 rotates with the third connecting rod 77. Since the I-shaped collecting shaft 78 is threadedly connected to the reciprocating wire rod 771, the I-shaped collecting shaft 78 will reciprocate, and the third connecting rod 77 can also rotate with the I-shaped collecting shaft 78 at the same time, so that the spinning without excess moisture on the surface can be collected.

[0038] Further, such as Figure 2 and Figure 3 As shown, a support plate 21 is fixedly connected to the top of the four support legs 2, a first groove 211 is provided on the top of the support plate 21, the mixing box 3 is fixedly installed on the top of the support plate 21, a first motor 31 is fixedly installed on the top of the mixing box 3, a feed port 32 is provided on the top of the mixing box 3, and the output shaft of the first motor 31 passes through the top of the mixing box 3 and is fixedly connected to a mixing shaft 33;

[0039] Two first connecting rods 34 are fixedly installed on the outer surface of the stirring shaft 33, and one end of the two first connecting rods 34 is fixedly connected to a first scraper 341. A second scraper 342 is fixedly connected to the bottom of the stirring shaft 33, and the bottom of the second scraper 342 is close to the bottom of the inner surface of the stirring box 3. A second groove 37 is opened at the bottom of the stirring box 3, and the second groove 37 is connected with the first groove 211.

[0040] Four second connecting rods 35 are fixedly installed on the outer surface of the stirring shaft 33. The four second connecting rods 35 are divided into two groups, two by two. The two second connecting rods 35 in the same group are commonly fixedly connected to a rotating shaft 351. The outer surface of the rotating shaft 351 is rotatably connected to a stirring plate 352. The outer surface of the stirring shaft 33 is fixedly connected to a connecting ring 36. The outer surface of the connecting ring 36 is evenly and fixedly connected to two spoilers 361.

[0041] Before spinning, the spinning raw materials need to be stirred evenly before being used for spinning. In actual use, since the spinning raw materials are more viscous and are composed of multiple raw materials, it is not only necessary to stir the spinning raw materials evenly, but also necessary to consider the possibility that the spinning raw materials may stick to the inner wall of the stirring box 3.

[0042] During production, the spinning raw material is first put into the stirring box 3 through the feed port 32, and then the first motor 31 drives the stirring shaft 33 to rotate. When the stirring shaft 33 rotates, the stirring shaft 33 drives the first scraper 341 to scrape the inner surface side wall of the stirring box 3 through the two first connecting rods 34, and at the same time, the second scraper 342 connected to the bottom of the stirring shaft 33 can scrape the inner surface bottom wall of the stirring box 3. The first scraper 341 cooperates with the second scraper 342 to clean the part of the stirring box 3 that can contact the spinning raw material, so as to prevent the spinning raw material from sticking to the inner wall of the stirring box 3 and reducing the service life of the stirring box 3.

[0043] When the stirring shaft 33 rotates, the second connecting rod 35 and the connecting ring 36 will also rotate. When the connecting ring 36 rotates, it will also rotate with the spoiler 361. The connecting ring 36 is a triangular prism structure. When it rotates, the connecting ring 36 can make the raw materials in the stirring box 3 fluctuate up and down, and adjust the raw materials in the stirring box 3 up and down to improve the stirring efficiency. At the same time, the two stirring plates 352 will also rotate to stir the spinning raw materials in the stirring box 3. Multiple components stir the spinning raw materials in the stirring box 3, and the spinning raw materials can be stirred more evenly.

[0044] Further, such as Figure 4As shown, the bottom of the support plate 21 is fixedly connected to a silk making box 41, the bottom of the silk making box 41 is fixedly connected to a silk outlet head 42, the first groove 211 passes through the inner cavity of the silk making box 41, one side of the water tank 1 is fixedly connected to a water suction pipe 51, one end of the water suction pipe 51 passes through the inner cavity of the water tank 1, the other end of the water suction pipe 51 is fixedly connected to a water pump 52, the water pump 52 is fixedly installed on one side of the water tank 1, the top of the water pump 52 is fixedly connected to a water outlet pipe 53, the water outlet pipe 53 passes through the inner cavity of the water tank 1, and the water outlet pipe 53 and the silk outlet head 42 are on the same vertical plane.

[0045] After the stirring is completed, the spinning raw material enters the spinning box 41, and is ejected from the spinning head 42 after extrusion spinning. The ejected spinning will directly fall into the water in the water tank 1 for cooling. At this time, under the action of the water pump 52, the water in the water tank 1 is pumped out through the water suction pipe 51, and then ejected into the water tank 1 through the water outlet pipe 53. When the spinning head 42 sprays the spinning into the water in the water tank 1, the water ejected from the water outlet pipe 53 will cause the water to flow, and at the same time, the spinning falling into the water tank 1 will be blown to the other side, preventing the spinning from directly sinking to the bottom of the water tank 1 and gathering, affecting the collection of the spinning. At the same time, since the temperature of the newly produced spinning is too high, the position where the produced silk falls into the water tank 1 is fixed. During production, the water temperature of the water tank 1 area located at the silk drop position will be higher than the surrounding water temperature. The water pump 52 can circulate the water in the water tank 1 to avoid the water temperature in some areas being too high and affecting the cooling of the spinning.

[0046] Further, such as Figure 5 and Figure 6 As shown, a plurality of limiting rings 61 are fixedly installed on the bottom of the inner surface of the water tank 1, an L-shaped guide tube 62 is fixedly installed on the bottom wall of the inner surface of the water tank 1, and a first bracket 63 is fixedly installed on the bottom wall of the inner surface of the water tank 1. The first bracket 63 is located on one side of the L-shaped guide tube 62, and the second bracket 64 is located on one side of the first bracket 63. The middle parts of the first bracket 63 and the second bracket 64 are both rotatably installed with a discharging assembly;

[0047] The discharging assembly includes a third groove 641, which is opened on both sides of the second bracket 64. The outer surfaces of the first material guide column 642 and the second material guide column 646 are both provided with grooves. Slide blocks 643 are rotatably installed on both sides of the first material guide column 642. The slide blocks 643 are slidably installed on the inner surface of the third groove 641. A first telescopic rod 645 is fixedly installed at the bottom of the slide block 643. A spring 644 is wound and connected on the outer surface of the first telescopic rod 645.

[0048] A fourth groove 648 is formed on one side of the second bracket 64, and a connecting block 647 is fixedly connected to the second material guide column 646 on the same side. The connecting block 647 is rotatably mounted on the inner surface of the fourth groove 648;

[0049] A fourth connecting rod 79 is fixedly connected to one side of the connecting block 647, a second connecting plate 74 is fixedly connected to the top of the water tank 1, the fourth connecting rod 79 penetrates the second connecting plate 74 and is fixedly connected to the output shaft of the second motor 72, a first connecting plate 71 is fixedly connected to one side of the water tank 1, and the second motor 72 is fixedly mounted on the top of the first connecting plate 71.

[0050] During production, the spinning is water-cooled in the water tank 1, and entanglement and knotting may occur. Therefore, the spinning is restricted by passing through a plurality of limit rings 61, which can effectively prevent the spinning from moving around and knotting in the water tank 1. Finally, the spinning is discharged through the L-shaped duct 62. The spinning first passes through the first bracket 63, and the discharge assembly in the first bracket 63 restrains the spinning. Then, driven by the second motor 72, the fourth connecting rod 79 rotates with the connecting block 647, and the connecting block 647 rotates with the second guide column 646. Under the action of the spring 644, the slider 643 slides on the inner surface of the third groove 641, and the first guide column 642 presses against the second guide column 646, and the spinning passes between the second guide column 646 and the first guide column 642. The second guide column 646 and the first guide column 642 pressurize the spinning to clean up excess moisture on the spinning surface. At the same time, due to friction, the second guide column 646 can also drive the spinning to move when it rotates.

[0051] Further, such as Figure 7 and Figure 8 As shown, the third connecting plate 76 and the fourth connecting plate 761 are fixedly installed on both sides of the water tank 1, the second pulley 751 is rotatably installed on one side of the third connecting plate 76, one end of the reciprocating screw rod 771 is rotatably installed on one side of the fourth connecting plate 761, the third connecting rod 77 rotates through the third connecting plate 76 and is fixedly installed on one side of the second pulley 751, the outer surface of the third connecting rod 77 is fixedly connected with a fixed disk 772, and the fixed disk 772 and the opposite surface of the I-shaped collecting shaft 78 are jointly fixedly connected with four second telescopic rods 7721, a fifth groove 781 is opened on one side of the I-shaped collecting shaft 78, and a threaded sleeve 782 is rotatably installed on the inner surface of the fifth groove 781, and the reciprocating screw rod 771 is threadedly installed on the inner surface of the threaded sleeve 782.

[0052] When collecting the spun yarn, when the second motor 72 rotates, the third connecting rod 77 will also rotate through the belt 75 and the second pulley 751. When the third connecting rod 77 and the reciprocating wire rod 771 rotate, the threaded sleeve 782 will drive the I-shaped collection shaft 78 to move back and forth along the reciprocating wire rod 771, and the fixed plate 772 will rotate with the I-shaped collection shaft 78 through the four second telescopic rods 7721. When the I-shaped collection shaft 78 reciprocates, the four second telescopic rods 7721 will retract and retract with the movement of the I-shaped collection shaft 78. By making the I-shaped collection shaft 78 reciprocate while rotating, the I-shaped collection shaft 78 can collect the spun yarn more evenly, and the spun yarn can be evenly wound around the outer surface of the I-shaped collection shaft 78, which is convenient for subsequent processing and use of the spun yarn.

[0053] Working principle: first, the spinning raw material is put into the stirring box 3 through the feed port 32, and the output shaft of the first motor 31 drives the stirring shaft 33 to rotate. When the stirring shaft 33 rotates, it drives the first scraper 341 and the second scraper 342 to rotate. The first scraper 341 can clean up the spinning raw material at the bottom of the stirring box 3, and the first scraper 341 can clean up the spinning raw material stuck on the side wall of the inner surface of the stirring box 3, and move the spinning raw material at the edge of the stirring box 3 to the middle of the stirring box 3, which is conducive to making the spinning raw material more evenly stirred. When the stirring shaft 33 rotates, the stirring plate 352 and the spoiler 361 will also rotate to stir the spinning raw material in the stirring box 3;

[0054] After the stirring is completed, the spinning material enters the spinning box 41 through the second groove 37, and the spinning material is extruded to generate spinning. The spinning enters the water in the water tank 1 through the spinning head 42 for cooling. The spinning entering the water tank 1 is disturbed by the water sprayed from the outlet pipe 53, which effectively prevents the spinning from gathering and sticking together in the water tank 1. Then the spinning passes through the limiting ring 61 and comes out from the top of the L-shaped guide tube 62 to enter the first bracket 63, and the excess water on the spinning surface is cleaned for the first time. Then the spinning passes between the second guide column 646 and the first guide column 642 to clean the excess water on the spinning surface again. At the same time, due to the The combined effect of the discharge assembly in the first bracket 63 and the second bracket 64, combined with the rotation of the second guide column 646, can generate a certain pulling force on the spinning between the first bracket 63 and the second bracket 64, so as to make the spinning more compact when collecting the spinning. When the second motor 72 rotates, the belt 75 and the second pulley 751 drive the fixed plate 772 to cooperate with the four second telescopic rods 7721 to rotate the I-shaped collection shaft 78 to collect the spinning. The reciprocating wire rod 771 cooperates with the threaded sleeve 782 to make the I-shaped collection shaft 78 reciprocate, so that the I-shaped collection shaft 78 can collect the spinning more evenly.
