Description

Technical Field

[0001] The present invention relates to the technical field of chemical fibers, in particular to a device for producing high-strength composite fibers. Background Art

[0002] In recent years, a variety of high-performance composite fiber materials have been successfully developed, such as carbon fiber, aramid fiber and ultra-high molecular weight polyethylene fiber. The performance of carbon fiber has been continuously improved. By improving the production process and raw materials, its strength and modulus have been further improved, and the production cost has gradually decreased, making the large-scale application of carbon fiber in more fields possible. Aramid fiber is widely used in military, protection and other fields due to its excellent high temperature resistance, high strength and high toughness. In addition, the emergence of ultra-high molecular weight polyethylene fiber provides lightweight and high-strength solutions for ropes, bulletproof materials, etc. The unique properties of these new fibers provide a rich selection of raw materials for the development of high-strength composite fiber materials, and promote the continuous innovation of composite fiber technology. Good manufacturing process and equipment technological innovation provide strong technical support for the large-scale industrial production of high-strength composite fiber materials, and promote the rapid development of the composite fiber industry.

[0003] However, the existing high-strength composite fiber production equipment still has the following problems during use: during the production process, after the melt enters the spinning box, it passes through the spinning calculation pump in the box to pass through the filter layer of the spinning assembly, and is extruded from the spinneret pores. The extruded melt stream is cooled by air into filaments. The aperture specifications of the spinneret and the air outlet mode of the cold air component are relatively simple. When there is a demand for processing high-strength composite fibers of different sizes, it is necessary to frequently change the spinneret and debug the cold air, which is cumbersome to operate. For the thickness of the high-strength composite fiber to be processed, the thicker the spindle, the larger the volume of the filaments formed in space, and the cooling air The difficulty of penetrating the gaps between the filaments will increase. During the cooling process, the thick filaments have a more obvious obstruction to the cooling air due to their own mass and surface area. For the same cooling air conditions, the heat exchange efficiency between the thick filaments and the cooling air is relatively low, and a longer cooling time and a larger cooling air volume are required to achieve the expected cooling effect. Conversely, when the cooling air speed and temperature are appropriate, the spinneret can quickly cool and solidify within the appropriate temperature range, making the structure of the filament more stable, which is beneficial to the subsequent stretching process, thereby obtaining thinner and stronger fibers, which need to be flexibly adjusted according to processing requirements.

[0004] Therefore, we propose a high-strength composite fiber production equipment to solve the above problems. Summary of the Invention

At the same time, adjustment holes of different specifications are provided on the adjustment plate. The adjustment plate forms a horizontal sliding structure through the arc groove, the limiting groove and the sliding cavity, and the area of ​​the adjustment plate can cover the spinneret hole.

[0013] Preferably, the transition assembly includes a cylinder arranged to fit the inner wall of the spinneret, and the bottom of the cylinder is integrally connected with a rubber cone mouth, and the rubber cone mouth is opposite to the center line of the spinneret and the adjustment hole, and the rubber cone mouth is adjusted to the size of the outlet by pulling with external force, and each time the size of the rubber cone mouth is adjusted, the opening size of the corresponding adjustment hole is adjusted.

[0018] Compared with the prior art, the beneficial effects of the high-strength composite fiber production equipment of the present invention are: when in use, the yarn thickness of the high-strength composite fiber yarn can be quickly adjusted according to processing requirements, and the air outlet state of the cold air component can be adaptively adjusted according to the yarn thickness, thereby improving the quality and performance of fiber production and improving processing efficiency. The specific contents are as follows:

[0019] 1. The wire-out adjustment component is set up so that the thickness of the fiber wire can be quickly adjusted when there are different price requirements. The shaft drives the circular plate to rotate. After the circular plate rotates, the arc groove rotates accordingly. The arc groove drives the adjustment plate to move accordingly. When the adjustment plate moves with the arc groove, it will also be limited by the limit groove, so that the adjustment plate slides horizontally inside the sliding cavity. After the adjustment plate slides, the adjustment hole of the corresponding specification on it will move to the position of the spinneret, thereby changing the thickness of the fiber wire when it is output. When there are different processing requirements, it can be quickly adjusted to improve processing efficiency;

[0020] 2. By setting up the transition component, in the process of adjusting the thickness of the wire, it is possible to avoid excessive residue of the melt in the spinneret, which may affect the wire production in the later stage. After the melt flows into the cylinder, it is discharged from the rubber cone at the bottom. The rubber cone is directly connected to the adjustment hole, so that when the melt is ejected, the residue of the melt in the spinneret is reduced to avoid affecting the subsequent wire production quality. When the shaft rotates, it also drives the gear to rotate synchronously. After the gear rotates, it drives the outer meshing gear ring to rotate synchronously. After the gear ring rotates, the guide groove at its bottom guides the pulling rod to slide horizontally. After the pulling rod slides, it drives the bottom fixed plate to open and close. After the fixed plate moves, it can change the opening size of the rubber cone, thereby corresponding to the size of the adjustment hole, and avoiding the solution from flowing into the gap between the spinneret and the adjustment plate.

[0021] 3. By setting up the air outlet adjustment component, the air outlet state of the cold air component can be adaptively adjusted when the thickness of the yarn is different, thereby improving the quality and performance of fiber production. The shaft drives the threaded section to rotate, and after the threaded section rotates, it drives the pressure plate to move downward in the oil chamber, thereby squeezing the oil in the oil chamber and transporting it to the inside of the fixed cylinder. The push plate is pushed out, and after the push plate slides out, it pushes the wind resistance plates on the upper and lower sides to rotate synchronously, thereby adjusting the air outlet area. When the air outlet volume remains unchanged, the smaller the air outlet area, the higher the wind speed and the lower the temperature. In addition, with the setting of the spiral blades, the wind can be in more comprehensive contact with the fiber yarn when passing through it, making the air cooling more uniform and efficient.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0035] See also Figure 1 - Figure 11 As shown, the present invention provides a technical solution: a high-strength composite fiber production device, comprising a spinning box 1, wherein the top of the spinning box 1 is connected to the outlet of the distribution pipe 2, and a filter layer 3 is fixedly installed in the middle of the inner side of the spinning box 1, a spinneret 4 is installed at the bottom of the inner side of the spinning box 1, and spinneret holes 5 are provided at equal angles through the edge of the spinneret 4, and a cold air duct 6 is installed in the middle of the bottom surface of the spinneret 4, and air outlets 7 are opened at equal angles on the side of the cold air duct 6;

[0036] First, the basic operation of the device is introduced. After the molten material enters the spinning box 1 from the distribution pipe 2, it passes through the filter layer 3 to intercept impurities and then hits the spinneret 4. The fluid inside the spinning box 1 is then ejected at high speed through the spinneret hole 5 to form fiber filaments. After the cold air pipe 6 is ventilated, cold air will be blown out from the air outlet 7, thereby cooling the fiber filaments with air, which helps to stretch and solidify the fiber filaments. The fiber filaments can be quickly cooled and solidified within the appropriate temperature range, making the structure of the filaments more stable, which is conducive to subsequent stretching processing, thereby obtaining finer and stronger fibers.

[0037] Example 1: In order to quickly adjust the thickness of high-strength composite fiber yarn according to processing requirements, the following solution is proposed. Please refer to Figure 4 - Figure 9 As shown;

[0038] A motor 8 is installed on the bottom surface of the spinneret 4, and the output end of the motor 8 is connected to the shaft 9 through a sprocket mechanism, and the top of the shaft 9 passes through the bearing and is connected to the inner side of the middle part of the spinneret 4, and the shaft 9 is connected to the wire outlet adjustment assembly 10, the wire outlet adjustment assembly 10 is arranged on the lower inner side of the spinneret 4, and the wire outlet adjustment assembly 10 quickly adjusts the thickness of the fiber wire according to the processing requirements, and the wire outlet adjustment assembly 10 includes a circular plate 101 fixedly mounted on the bottom of the shaft 9, and the circular plate 101 is rotatably connected to the inner bottom of the spinneret 4, and the top of the circular plate 101 is provided with an arc groove 102 at equal angles, and an adjustment plate 103 is slidably connected to the arc groove 102, and the adjustment plate 103 is set to an "L" shape structure;

[0039] During use, when it is necessary to process fiber filaments of different thicknesses, the motor 8 at the bottom of the spinneret 4 is started, and the output end of the motor 8 drives the shaft 9 to rotate synchronously through the sprocket mechanism. The shaft 9 rotates and drives the circular plate 101 to rotate. The circular plate 101 rotates and the arc groove 102 at the top rotates accordingly. The arc groove 102 rotates and drives the adjustment plate 103 to move accordingly.

[0040] refer to Figure 4 - Figure 9 As shown, the middle part of the adjustment plate 103 is slidably connected to the rectangular limiting groove 104, and the limiting groove 104 is opened at an equal angle inside the spinneret 4, and the top of the adjustment plate 103 is slidably connected to the sliding cavity 105, and the sliding cavity 105 is horizontally connected to the middle part of the spinneret 5. At the same time, adjustment holes 106 of different sizes are provided on the adjustment plate 103. The adjustment plate 103 forms a horizontal sliding structure through the arc groove 102, the limiting groove 104 and the sliding cavity 105, and the area of ​​the adjustment plate 103 can cover the spinneret 5;

[0041] During use, the adjustment plate 103 will be limited by the limit groove 104 as it moves with the arc groove 102, so that it can only slide horizontally inside the sliding cavity 105. After the adjustment plate 103 slides, the adjustment hole 106 of the corresponding specification on it will move to the position of the spinneret 5, thereby changing the thickness of the fiber yarn when it is output. When there are different processing requirements, it can be quickly adjusted to improve processing efficiency.

[0042] Example 2: In order to avoid the situation where too much melt remains in the spinneret hole 5 during the process of adjusting the thickness of the wire, which may affect the wire production in the later stage, the following solution is proposed. Please refer to the following for details. Figure 2 、 Figure 4 - Figure 8 and Figure 10 As shown;

[0043] The transition component 11 is arranged on the inner upper part of the spinneret 4 and inside the spinneret hole 5, and the transition component 11 prevents the melt from remaining in the spinneret hole 5 when the fiber filament is adjusted in thickness. The transition component 11 includes a cylinder 111 arranged in contact with the inner wall of the spinneret hole 5, and the bottom of the cylinder 111 is integrally connected with a rubber cone 112, and the rubber cone 112 is directly opposite to the center line of the spinneret hole 5 and the adjustment hole 106, and the rubber cone 112 is adjusted to the outlet size by external force. At the same time, each time the size of the rubber cone 112 is adjusted, the opening size of the corresponding adjustment hole 106 is adjusted;

[0044] When in use, the cylinder 111 fits against the inner wall of the spinneret hole 5, so that the melt can directly flow into the interior of the cylinder 111 and then be discharged from the rubber cone 112 at the bottom of the cylinder 111. The rubber cone 112 is directly connected to the adjustment hole 106, thereby reducing the melt residue in the spinneret hole 5 when the melt is ejected, thereby avoiding affecting the subsequent wire quality;

[0045] refer to Figure 4 - Figure 7 and Figure 10 As shown, a fixing piece 113 is installed at an equal angle on the outside of the rubber cone 112, and a gear 114 is rotatably connected to the upper side of the spinneret 4, and the gear 114 is fixedly installed on the top outside of the shaft 9, and a gear ring 115 is meshed and connected to the outside of the gear 114 at an equal angle, and the gear ring 115 corresponds to the position of the spinneret hole 5 one by one, and a flower-shaped guide groove 116 is provided at the bottom of the gear ring 115, and a pulling rod 117 is slidably connected in the guide groove 116, and the pulling rod 117 is embedded and slidably connected to the outside of the spinneret hole 5, and the bottom of the pulling rod 117 is connected to the fixing piece 113, and the rubber cone 112 constitutes a caliber adjustment structure through the pulling rod 117;

[0046] During use, when the shaft 9 rotates, it will also drive the gear 114 to rotate synchronously. After the gear 114 rotates, it drives the outer meshing gear ring 115 to rotate synchronously. After the gear ring 115 rotates, the guide groove 116 at its bottom guides the pulling rod 117 to slide horizontally. After the pulling rod 117 slides, it drives the bottom fixing plate 113 to open and close. After the fixing plate 113 moves, it can change the opening size of the rubber cone mouth 112, thereby corresponding to the size of the adjustment hole 106, to prevent the solution from flowing into the gap between the spinneret hole 5 and the adjustment plate 103.

[0047] Example 3: In view of the different thickness of the yarn, the air outlet state of the cold air component is adaptively adjusted to improve the quality and performance of the fiber production. Therefore, the following solution is proposed. Please refer to Figure 3 、 Figure 6 and Figure 10 - Figure 11 As shown;

[0048] The air outlet regulating assembly 12 is arranged in the middle of the inner side of the spinneret 4 and inside the air outlet 7, and the air outlet regulating assembly 12 adaptively adjusts the air outlet volume after the thickness of the yarn output changes. The air outlet regulating assembly 12 includes an oil chamber 121 opened in the middle of the inner side of the spinneret 4, and the middle part of the oil chamber 121 passes through the sealed bearing and is connected to the shaft 9, and the outer side of the shaft 9 is integrally provided with a threaded section 122, and the outer side of the threaded section 122 is threadedly connected to a pressure plate 123, and the pressure plate 123 and the oil chamber 121 are vertically fitted and slidable;

[0049] During use, when adjusting the thickness of the wire, the shaft 9 also drives the threaded section 122 to rotate synchronously in the oil chamber 121. After the threaded section 122 rotates, it drives the pressing plate 123 to move downward in the oil chamber 121, thereby squeezing the oil in the oil chamber 121 into the interior of the fixed cylinder 124.

[0050] refer to Figure 10 - Figure 11 As shown, the oil chamber 121 is connected to the fixed cylinder 124 through a connecting pipe, and the fixed cylinder 124 is symmetrically fixed to the upper and lower inner walls of the air outlet 7. A push plate 125 is slidably connected to the outlet of the fixed cylinder 124. Both the fixed cylinder 124 and the push plate 125 are configured as arc structures. At the same time, the end of the push plate 125 is fixedly connected to the air blocking plate 126. The air blocking plate 126 is symmetrically hinged to the upper and lower inner walls of the air outlet 7. A spiral blade 127 for guiding air is provided in the middle of the air outlet 7.

[0051] During use, after the oil enters the fixed cylinder 124, the push plate 125 is pushed out. After the push plate 125 slides out, it pushes the wind blocking plates 126 on the upper and lower sides to rotate synchronously, thereby adjusting the air outlet area of ​​the air outlet 7. When the air outlet volume remains unchanged, the smaller the air outlet area, the higher the wind speed and the lower the temperature. In addition, in conjunction with the setting of the spiral blades 127, the wind can be in more comprehensive contact with the fiber filaments when passing through the fiber filaments, thereby making the air cooling more uniform and efficient.
