Description

Technical Field

[0001] The present invention relates to the technical field of electronic yarns, and in particular to a 6.5 μm electronic yarn drawing device. Background Art

[0002] Existing electronic yarn drawing devices generally consist of components such as a spinneret, a cooling component, an oiling box, and a beam former.

[0003] The spinneret used has eight partitions (hereinafter referred to as "eight-way drawing"). The eight-way drawing spinneret has a low flow rate of molten glass per unit time, resulting in low production efficiency. The thickness of the eight-way drawing electrode and the aperture of the nozzle are not suitable for operating at the set high temperature, and cannot meet the high-speed spinning process requirements. During the use of the eight-way drawing spinneret, the temperature of the outer nozzles in a single zone is lower than that of the nozzles in other areas, and the tension is larger than that in other areas, which easily causes quality abnormalities such as flying filaments and hairiness.

[0004] During the drawing process, the weight of the filament bundle is directly related to the cooling effect of the cooling fins. The regulator is used to adjust the distance between the spinneret and the cooling fins, and the size of this distance directly affects the temperature of the molten glass, thereby affecting the weight of the filament bundle.

[0005] The oiling box cover mainly serves to block the spray water, that is, to prevent the strong airflow around the spinneret from being driven rapidly downward by the filament bundle, which causes too large an airflow at the rubber sheet when the filament bundle passes through the rubber sheet, and the sizing agent cannot be better carried away by the rubber sheet, seriously affecting the oiling effect of the filament bundle.

[0006] During the use process, the beam former has a single bracket carrying a single beam former wheel. Multiple beam former brackets result in a small space, and during the production process, individual adjustments are required. There will be a large difference in individual adjustments, and it is not easy to adjust to the same level. Moreover, the weight of a single beam former device is large, causing a large weight on the main beam and resulting in deformation of the main beam, which cannot meet the production process requirements.

[0007] Main problems and disadvantages:

[0008] 1. The eight-way drawing spinneret has low production efficiency, high unit production cost, and insufficient market competitiveness. The thickness of the eight-way drawing electrode and the aperture of the nozzle are not suitable for setting a high temperature, and cannot meet the high-speed production process requirements;

[0009] 2. When using the existing cooling fin regulator to adjust the height of the cooling fins with a special tool, since the moving part and the fixed part are in a semi-latching sliding groove, there is a large shaking space. When adjusting the distance between the cooling fins and the spinneret, there are problems of shaking and uneven speed, resulting in large fluctuations in TEX (weight of every 100-meter filament bundle), and the predetermined adjustment effect cannot be achieved, seriously affecting the product quality;

[0010] 3. When the oiling device is in normal use, the protection plate is generally placed on the oiling box cover after being turned backward. When not oiling, the protection plate is turned forward to protect the rubber sheet. However, when the protection plate is placed on the oiling cover after being turned backward, due to the obstruction of the baffle, water droplets often remain. When turned forward, the water droplets are also likely to fall into the box cover, diluting the wetting agent and affecting the product quality.

[0011] 4. The adjustment range of the bunching wheel is small and it is not easy to meet the requirements of process improvement. Moreover, the bunching device bracket is heavy, and the large weight will cause the crossbeam to deform and vibrate, affecting the quality. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0044] Such as Figure 1 、 2As shown in the figure, this embodiment provides a 6.5μm electronic yarn drawing device, which includes a spinneret 1, a cooling component 2, an oiling component 3, and a bunching component 4.

[0045] The spinneret 1 is installed at the bottom of the spinneret brick 5. The spinneret 1 has a trough-shaped structure, with a liquid flow trough in the middle for containing molten glass. There are multiple drawing areas at the bottom, and each drawing area is evenly distributed with a number of nozzles 6 in an array. Multiple groups of electrodes 7 are connected to the outer side of the spinneret 1. The molten glass in the spinneret 1 can be heated through the electrodes 7 and flows out through the nozzles 6 to form a continuous molten glass filament bundle and fall down.

[0046] Among them, the number of drawing areas is twelve, and each drawing area is evenly distributed with a number of nozzles 6. The diameter of the nozzles 6 is between 1.25mm and 1.65mm. By increasing the number of drawing areas of the spinneret 1 from eight to twelve, the flow rate of the molten glass is increased and the production efficiency is improved.

[0047] The thickness of the electrode 7 is between 4.1mm and 4.3mm, and the distance between the endpoints of the electrodes 7 at both ends of the spinneret 1 is between 481mm and 485mm.

[0048] Specifically, the diameter of the nozzle 6 is 1.5mm, the thickness of the electrode 7 is 4.2mm, and the distance between the endpoints of the electrodes 7 at both ends of the spinneret 1 is 483mm. By adjusting and increasing the thickness of the electrode 7, the set temperature of the spinneret 1 can be increased, and the effective control of the temperature of the spinneret 1 is increased. By increasing the aperture of the nozzle 6, the flow rate of the molten glass increases at the same temperature of the spinneret 1, achieving the purpose of increasing the drawing speed, and optimizing the distribution of the peripheral nozzles 6, reducing the deviation of tension caused by uneven temperature between the peripheral and central regions of the same partition, which is likely to cause quality problems such as flying filaments and fluff.

[0049] As Figure 3 、 4 、Figure 5 shows, the cooling component 2 is installed below the spinneret 1, including multiple groups of regulators 8 and multiple cooling blades 9 arranged in parallel on one side. The vertical distance between the cooling blades 9 and the bottom of the spinneret 1 can be adjusted by the regulators 8. The surfaces of the cooling blades 9 are arranged vertically and are spaced horizontally from the nozzles 6, so that the molten glass filament bundle falling from the nozzles 6 passes between the cooling blades 9, and the filament bundle is cooled under the action of the circulating cooling water in the cooling blades 9.

[0050] At the top of the regulator 8, there is a powerful clamp head 10 extending therefrom. The extending length of the powerful clamp head 10 is adjustable. The powerful clamp head 10 and the right side of a fixed block 11 are detachably installed through bolt cooperation. The cooler water jacket 12 is installed in cooperation with the left side of the fixed block 11. The cooling fins 9 are installed in the installation groove on the left side of the cooler water jacket 12 and are connected to the cooler water jacket 12. On the right side of the fixed block 11 and the regulator 8, there is a right-angle angle steel for limiting its angle to prevent the fixed block 11 from deviating from the horizontal direction.

[0051] At both ends of the cooler water jacket 12, there are respectively a water inlet pipe 13 and a water outlet pipe 14 connected thereto. The ends of the water inlet pipe 13 and the water outlet pipe 14 far from the cooler water jacket 12 are respectively connected to an external cooling water source. The cooling water can flow into the cooler water jacket 12 from the external cooling water source through the water inlet pipe 13, enter the cooling fins 9 from it, cool the tow passing between the cooling fins 9. After the cooling water in the cooling fins 9 absorbs heat and rises in temperature, it flows into the cooler water jacket 12, and then flows back to the external cooling water source through the water outlet pipe 14 to realize the circulation of the cooling water.

[0052] The vertical position of the cooling fins 9 can be adjusted under the action of the regulator 8, so as to use the recyclable cooling water in the cooling fins 9 to control the local temperature of the spinneret 1, and better ensure the overall temperature of the spinneret 1 is consistent, reducing or avoiding the phenomenon of difficult operation and unstable product quality caused by the regulator 8 during adjustment.

[0053] As Figure 6 shown, the oiling component 3 includes an oiling box 15 and an oiling box cover arranged thereon. An oiling roller shaft is provided in the oiling box 15, and an oiling rubber sheet is attached to the surface of the oiling roller shaft. The oiling roller shaft can rotate under the action of a motor, driving the oiling rubber sheet to dip the sizing agent in the oiling box 15 to oil and infiltrate the tow, so as to improve the oil content and toughness of the tow.

[0054] The oiling box cover includes an upper cover plate 16 and a lower cover plate 17. The front end of the upper cover plate 16 is arranged obliquely upward relative to the surface of the lower cover plate 17. The front end of the lower cover plate 17 is slightly inclined upward relative to the horizontal plane, and the front end of the upper cover plate 16 can rotate relative to the oiling box 15. The rear end of the upper cover plate 16 is attached to the rear end of the lower cover plate. The distance between the front end of the lower cover plate and the tow is 2 mm to 4 mm, and the thickness of the upper cover plate is 1.5 mm to 2 mm.

[0055] The front edge of the upper cover plate 16 is fixedly connected to a support rod 18. The support rod 18 is horizontally arranged, and its two ends are respectively connected to a rotating rod 19 in a mating manner. The bottom end of the rotating rod 19 is rotatably connected to the side surface of the oiling box 15 in a mating manner. The right side surface of the rotating rod 19 is fixedly connected to a support column 20. The support column 20 is arranged obliquely downward relative to the rotating rod 19. After the rotating rod 19 rotates to the right, the bottom end of the support column 20 abuts against the surface of the lower cover plate 17, causing the front end of the upper cover plate 16 to rotate upward and open. Since an opening is provided in the middle of the lower cover plate 17, after the upper cover plate 16 is opened, sizing agent can be added or replaced into the oiling box 15 through the opening. The rear end of the upper cover plate 16 can support the tow. After the oiling roller shaft located in the oiling box 15 rotates, the oiling rubber dips the sizing agent in the oiling box 15 and oils and wets the tow hanging from the rear end of the upper cover plate 16.

[0056] The beam collecting component 4 includes multiple groups of beam collectors. Each beam collector is slidably installed on the same strip-shaped mounting frame, and the strip-shaped mounting frame is fixed to the cross beam.

[0057] The specific installation method of the beam collecting component 4 is as follows: (1) Install 12 sliding beam collectors on a stainless steel strip of 855mm * 20mm; (2) Fix it to the cross beam through M6 screws on the left and right sides, and adjust the front and rear positions of the steel strip through the included angle required by the process; (3) Ensure that the horizontal heights are the same through round steel bars and fix them with M6 screws; (4) Since the rotation angles of different position numbers are different, reserve positions that can be adjusted back and forth; (5) Determine the positions of the beam collectors according to the knurled wheels and yarns and fix them with M6 screws, so as to meet the production requirements.

[0058] The wire drawing device further includes a wire arranging shaft 21 and a winding roller 22. There are multiple groups of wire arranging shafts 21, which are arranged below the beam collecting component 4 and are used to regularly arrange the tow to prevent the tow from being entangled. The winding roller 22 is arranged below the wire arranging shaft 21 and is used to wind the arranged silk thread on the outer peripheral surface of the winding roller 22.

[0059] In summary, in this embodiment, the 6.5μm electronic yarn wire drawing device has the following advantages:

[0060] 1. Increase the number of leakage plate wire drawing areas to twelve, improve the glass liquid flow rate, and enhance production efficiency. According to the simulated power of the leakage plate 1, determine the electrode thickness of 4.2mm and the distance between the two end electrodes 7 of 483mm, improve the settable leakage plate temperature, and increase the effective control of the leakage plate temperature; set the nozzle aperture to 1.5mm, increase the glass liquid flow rate of the leakage plate at the same temperature, achieve the purpose of increasing the wire drawing speed, optimize the peripheral nozzle distribution, and reduce the quality abnormalities such as flying wires and hairiness caused by relatively large tension compared with other areas;

[0061] 2. The cooling component 2 drives the up-and-down adjustment of the cooling blades 9 on one side of the fixed block 11 in an up-and-down movement manner, thereby using the circulating cooling water in the cooling blades 9 to control the local temperature of the leakage plate 1, which can better ensure the consistency of the overall temperature of the leakage plate. During the adjustment, it reduces and avoids the phenomena of difficult operation and unstable product quality caused by the regulator;

[0062] 3. Improve the oiling box 15 of the oiling component 3, so that there is no water dripping at the oiling rubber of the oiling component 3, and greatly relieve the wind ripples at the oiling rubber caused by the air flow, enabling the sizing agent to be evenly coated on different positions of the tow, providing a guarantee for the consistency of the oil content of the tow, and being of great significance for improving the product quality;

[0063] 4. The clustering component 4 improves the bracket for clustering, increasing the space relatively, reducing the weight borne by the cross beam to about 1 / 3 of the original, solving the problem of cross beam deformation, and removing the clustering bracket also saves costs, making each clusterer located in the same horizontal plane, which is more convenient for unified adjustment.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
