Description

Technical Field

[0001] This invention relates to the field of wire drawing machine equipment, and more particularly to a wire drawing machine take-up structure and the wire drawing process used therein. Background Technology

[0002] In fiberglass production, the drawing machine is one of the core pieces of equipment. With the industry’s increasing demand for production capacity, the four-head multi-drawing drawing machine will gradually become the mainstream equipment because it can produce multiple yarn bundles at the same time.

[0003] Currently, in the fiber drawing machine's processing steps, cooling water is continuously sprayed onto the yarn spool during the winding process at the machine head to cool the yarn and further ensure the performance of the wound yarn spool. However, existing equipment lacks an emergency execution component when the water flow is interrupted, causing the equipment to continue operating. This leads to various problems with the wound yarn spool, such as yarn sticking and inability to be unwound.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0005] To address the aforementioned deficiencies, the present invention aims to provide a yarn drawing machine take-up structure and a yarn drawing process, which can change the deflection angle of the guide component according to the water pressure. When the water flow is insufficient and the deflection angle is large enough, the yarn will contact the blade to achieve yarn cutting. This ensures that the equipment has an emergency execution component when the water flow is blocked, thus guaranteeing high-quality output from the equipment.

[0006] To achieve the above objectives, the present invention provides a yarn take-up structure for a yarn drawing machine, comprising: a frame; a winding head movably mounted on the frame; the winding head having a center around which yarn is wound; a first driving component mounted on the frame, having a driving end that reciprocates along a direction extending around the center; a guiding component movably mounted on the driving end, having a drawing hole through which yarn passes; a cutter provided on one side of the drawing hole; and a spraying component mounted on the driving end, including a nozzle with its output end facing the winding head and a sensing component connected to the nozzle for sensing water pressure; when the sensed water pressure is lower than a predetermined threshold s, the yarn driving through the drawing hole tends to approach the cutter.

[0007] According to the wire drawing machine take-up structure of the present invention, the frame is provided with at least one set of wire drawing mechanisms, and each set of wire drawing mechanisms is provided with a guide component and a spraying component.

[0008] According to the wire drawing machine take-up structure of the present invention, the wire drawing mechanism includes a rotating disk and at least two sets of winding heads rotatably mounted on the rotating disk; the rotating disk rotates intermittently at a predetermined angle, so that one of the winding heads is in the working position.

[0009] According to the yarn take-up structure of the drawing machine of the present invention, the sensing component includes: a water tank connected to the drive end, the outer wall of which has a water inlet and a water outlet connected to the nozzle; a push plate installed in the water tank, which forms a water pressure sensing space with the water tank wall; an elastic element connected to the push plate, used to drive the push plate to have a tendency to close the water pressure sensing space; a movable rod, one end of which is connected to a guide component, and the other end extends to the inner water tank and is connected to the push plate; water flows through the water pressure sensing space, the water pressure and the elastic force of the elastic element reach a balance, and the yarn passes through the center of the drawing hole; when the water pressure is lower than a predetermined threshold s1, the yarn passes through the center of the drawing hole at an angle.

[0010] According to the wire drawing machine take-up structure of the present invention, when the water pressure is lower than a predetermined threshold, the push plate drives the movable rod to rotate; the cutter is located on one side of the rotation direction of the wire drawing hole.

[0011] According to the yarn take-up structure of the drawing machine of the present invention, there is an oiling part between the drawing hole and the cutter for applying lubricating oil to the yarn at an angle to the center of the drawing hole.

[0012] According to the wire drawing machine take-up structure of the present invention, the cutter is inclined and forms a groove with the outer wall of the guide member to hold lubricating oil, so as to form an oiling part.

[0013] According to the yarn take-up structure of the drawing machine of the present invention, the guide component has a plurality of drawing holes of different diameters to accommodate yarns of different diameters.

[0014] The wire drawing process according to the present invention includes: Raw material melting: The prepared glass raw materials are heated to a high temperature of 1300℃-1600℃ in a tank furnace to fully melt them into molten glass. Precision feeding: The molten glass is transported to the drawing furnace under its own hydrostatic pressure or auxiliary pressure; the bottom of the baffle plate is evenly distributed with a large number of precision micropores; Temperature control and fiber forming: The stencil is maintained within a precise temperature range by electric heating to ensure that the viscosity of the molten glass flowing through the micropores reaches 1000 poise for wire drawing; under the action of gravity, the viscous molten glass flows out of the micropores in droplets; High-speed traction and cooling: The high-speed rotating drawing machine drum below exerts a strong traction force on the downward-flowing glass droplets; this force causes the glass liquid to be rapidly stretched, thinned, and cooled rapidly as it flows out of the micropores, solidifying into glass fiber monofilaments. Bundling and winding: Bundling: Hundreds of monofilaments drawn from all the micropores of the same sprue are coated with a sizing agent as they pass through the bundler; when the yarn bobbin on one head is full, the system automatically guides the raw yarn to another head to achieve uninterrupted continuous production; in current drawing machines, only one head is producing while the other head is waiting, ensuring uninterrupted production unless some monofilaments of the glass fiber itself break, in which case the machine will be forced to stop. Getting on the vehicle: This is the initial step in winding.

[0015] This invention provides a wire drawing machine take-up structure and the wire drawing process used therein, including: frame; A winding head is movably mounted on the frame. The winding head has a central area around which yarn is wound. The winding head is driven to rotate by a rotary motor. The winding head includes several ring-shaped tension bars and a support plate supporting the tension bars. When winding glass fiber yarn, the rotary motor drives the winding head to rotate, causing the yarn to wind onto the tension bars. A first driving component is mounted on the frame and has a driving end that reciprocates along the direction extending around the center. The first driving component can be a linear motor, with its base fixedly mounted on the frame. The extension and retraction direction of its output rod is parallel to the direction extending around the center. A guide component is movably mounted on the driving end and has an internal drawing hole for the yarn to pass through. A cutter is provided on one side of the drawing hole. The diameter of the drawing hole is set as needed. After the yarn is pulled through the drawing hole, it is stretched to the required diameter due to resistance, thus achieving the drawing process.

[0016] The guide component has multiple drawing holes of different diameters to accommodate yarns of different diameters.

[0017] As the first driving component drives the guide component to reciprocate, the yarn to be drawn is evenly wound onto the expansion strip along the extension direction around the center.

[0018] The spraying component, installed at the drive end, includes a nozzle with its output end facing the winding machine head and a sensing component connected to the nozzle for sensing water pressure. The nozzle sprays water to cool the yarn directly onto the yarn bundle at the winding machine head. The cooling serves two purposes: firstly, to reduce the yarn's adhesion and prevent the wound yarn from sticking together; secondly, to reduce the yarn's plasticity and increase its tensile strength.

[0019] When the sensing component detects that the water pressure is lower than a predetermined threshold s, it forces the yarn passing through the drawing hole to tend towards the cutter, thus cutting the yarn and preventing the tangled yarn from sticking together and affecting subsequent unwinding. This invention can change the deflection angle of the guide component according to the water pressure. When the water flow is insufficient and the deflection angle is large enough, the yarn will contact the blade, achieving the yarn cutting operation. This ensures the equipment has an emergency execution component in case of water flow obstruction, guaranteeing high-quality output. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the invention.

[0022] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0023] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0024] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0025] See Figure 1 , Figure 2 and Figure 3 This invention provides a wire drawing machine take-up structure and the wire drawing process used therein. The wire drawing machine take-up structure includes: Rack 1; A winding head 2 is movably mounted on the frame 1; the winding head 2 has a center around which yarn is wound; the winding head 2 is driven to rotate by a rotary motor; the winding head 2 includes a plurality of tension bars 21 arranged in a ring and a support plate supporting the tension bars 21. When winding glass fiber yarn, the rotary motor drives the winding head 2 to rotate, causing the yarn to be wound on the tension bars 21.

[0026] The first drive component 3 is mounted on the frame 1 and has a drive end that reciprocates along the direction of extension around the center. The first drive component 3 can be a linear motor, whose base is fixedly mounted on the frame 1, and the extension and retraction direction of its output rod is parallel to the direction of extension around the center.

[0027] Guide component 4, movably mounted on the drive end, has an internal drawing hole 41 for yarn to pass through; a cutter 42 is provided on one side of the drawing hole; the diameter of the drawing hole 41 is set as needed. After the yarn is pulled through the drawing hole 41, it is stretched to the required diameter due to resistance, thus realizing the drawing operation. For example, a 5mm yarn is drawn into a 3mm yarn after passing through a 3mm diameter drawing hole 41. Figure 5 (As shown).

[0028] Preferably, the guide component 4 has multiple drawing holes 41 of different diameters to accommodate yarns of different diameters.

[0029] As the first driving component 3 drives the guide component 4 to reciprocate, the yarn to be drawn is evenly wound onto the expansion strip 21 along the extension direction around the center.

[0030] The spraying component 5, installed at the drive end, includes a nozzle 51 with its output end facing the winding head 2 and a sensing component connected to the nozzle 51 for sensing water pressure. The nozzle 51 sprays water to cool the yarn and directly onto the yarn bundle on the winding head 2. The purpose of cooling is twofold: firstly, to reduce the adhesion of the yarn and prevent the wound yarn from sticking together; secondly, to reduce the plasticity of the yarn and increase its tensile strength.

[0031] When the sensing component detects that the water pressure is lower than a predetermined threshold s1, the yarn passing through the drawing hole 41 tends to move closer to the cutter 42. Specifically, the predetermined threshold s1 = 0, that is, when the sensing component detects that the water flow suddenly disappears, the yarn passing through the drawing hole 41 moves closer to the cutter 42, thereby cutting the yarn and preventing the tangled yarn from sticking together and affecting subsequent yarn feeding.

[0032] In some embodiments of the present invention, the frame 1 is provided with at least one set of drawing mechanisms, as shown in the figure. The frame 1 is provided with two sets of drawing mechanisms, one upper and one lower, and each set of drawing mechanisms is provided with a guide component 4 and a spraying component 5. During the winding operation, the upper and lower sets of drawing mechanisms work simultaneously to improve the efficiency of yarn winding.

[0033] Furthermore, the yarn drawing mechanism includes a rotating disk 11 and at least two sets of winding heads 2 rotatably mounted on the rotating disk, as shown in the figure. The winding heads 2 have two sets, including a first head and a second head. The rotating disk 11 rotates intermittently at a predetermined angle, so that one of the winding heads 2 is in a working position. During yarn winding, while the first head 2 is winding, the second head is unwinding the yarn spool, reducing the idle time of the equipment and improving the efficiency of yarn winding.

[0034] See Figure 4 In some embodiments of the present invention, the sensing component includes: Water tank 61 is connected to the drive end. Its outer wall has a water inlet 62 and a water outlet connected to the nozzle 51. Water flows into water tank 61 through water inlet 62 and is output through water outlet. Water tank 61 has a cylindrical structure.

[0035] The push plate 63 is installed in the water tank 61, forming a water pressure sensing space with the tank wall. When water flows through the water tank 61, the water pressure pushes the push plate 63 to rotate around the water tank 61 to a designated position to form the water pressure sensing space.

[0036] The elastic element 64, connected to the push plate 63, is used to drive the push plate 63 to tend towards closing the water pressure sensing space; when the water pressure pushes the push plate 63 to rotate, the elastic element 64 is compressed. When the water pressure is insufficient to maintain the water pressure sensing space, the push plate 63 is reversed and reset by the elastic action of the elastic element 64.

[0037] The movable rod 65 has one end connected to the guide component 4 and the other end extending to the inner water tank 61 and connecting to the push plate 63. Water flows through the water pressure sensing space, and the water pressure and the elastic force of the elastic element 64 reach equilibrium, allowing the yarn to pass through the center of the drawing hole 41. When the water pressure is lower than a predetermined threshold s1, the yarn passes through the center of the drawing hole 41 at an angle. When the water pressure is lower than the predetermined threshold, the push plate 63 drives the movable rod to rotate. The cutter 42 is located on the side of the wire drawing hole 41 in the direction of rotation.

[0038] During operation, under normal conditions, water flows through the water tank 61 and pushes the push plate 63 through water pressure to maintain the stability of the water pressure sensing space, further ensuring the stability of the working angle of the guide component 4, so that the yarn passes through the center of the drawing hole 41.

[0039] When the water flow suddenly disappears, the elastic element 64 uses the elastic drive push plate 63 to reset, thereby driving the movable rod to rotate and drive the yarn through the drawing hole 41 to approach the cutter 42, thus achieving the yarn cutting operation.

[0040] When the water pressure is low, the yarn does not come into contact with the cutter 42 because the water pressure is not zero but is lower than the normal water pressure. Since the water flow is present but insufficient, the problem cannot be solved without cutting. See Figure 5 Therefore, to solve the above problems, this application discloses an oiling section between the drawing hole 41 and the cutter 42, used to apply lubricating oil to the yarn at an angle to the center of the drawing hole 41. When the yarn passes through the oiling section, it will be coated with an oil layer and will not stick together. The cutter 42 is inclined, and it forms a groove 66 with the outer wall of the guide member 4 to hold the lubricating oil, thus forming the oiling section.

[0041] This invention also provides a fiber drawing process, which is an advanced glass fiber drawing process. Through innovative equipment layout (two sets of automatic reversing fiber drawing combinations, a total of 4 heads; one set consists of 2 heads, of which 1 head is working and 1 head is waiting) and dynamic control method, product quality and production efficiency are significantly improved.

[0042] I. Process Steps Raw material melting: The prepared glass raw materials (mainly composed of sandstone containing silica and various fluxes) are heated to a high temperature of 1300℃-1600℃ in a tank furnace to fully melt them into a glass melt with uniform viscosity and stable composition.

[0043] Precision feeding: Molten glass is precisely and stably conveyed into a drawing furnace (commonly known as a "spindle") made of platinum-rhodium alloy under its own hydrostatic pressure or auxiliary pressure. The bottom of the spindle is evenly distributed with numerous precision micropores (typically 1-2 mm in diameter). For example, this embodiment uses a 2400-pore spindle specifically for producing 100 tex, 136 tex, and 200 tex glass fiber bundles (linear density unit tex, i.e., the weight in grams of material per 1000 meters).

[0044] Temperature control and fiber forming: The stencil is electrically heated to maintain a precise temperature range slightly above the glass melting point, ensuring that the viscosity of the molten glass flowing through the micropores reaches approximately 1000 poise, optimal for wire drawing. Under the influence of gravity, the viscous molten glass flows out of the micropores in droplets.

[0045] High-speed traction and cooling: The high-speed rotating drum of the drawing machine below (with a speed of several thousand meters per minute) exerts a strong traction force on the downward-flowing molten glass droplets. This force causes the molten glass to be rapidly stretched, thinned, and cooled sharply the instant it flows out of the micropores, solidifying into glass fiber monofilaments.

[0046] Bundling and winding: Bundling: Hundreds of monofilaments drawn from all the micropores of the same spool are coated with a sizing agent as they pass through the bundler. This sizing agent plays a crucial role in protecting, lubricating, bundling, and bonding the fibers to the subsequent resin matrix. When the yarn bobbin on one head is full, the system automatically guides the raw yarn to another head (idle state), achieving uninterrupted continuous production. Further explanation: Current fiber drawing machines operate with only one head in production while the other waits, ensuring uninterrupted production unless a single filament breaks, in which case a shutdown is forced.

[0047] Getting on the vehicle: This is the initial step in winding.

[0048] For conventional wire drawing machines (1 turntable, 2 heads), after the equipment is started or under maintenance, the loading mechanism manually / automatically guides the raw yarn onto the winding spool of the running head. As the yarn laying mechanism moves into position step by step (within 12 seconds or less), the yarn enters the yarn laying hole and the winding begins, marking the start of normal operation.

[0049] The new equipment (2 turntables, 4 heads) operates independently in a single group (i.e., 1 turntable and 2 heads): After the equipment is started or under maintenance, the loading mechanism manually guides the raw yarn onto the winding spool of one of the heads. As the yarn-laying mechanism moves into position step-by-step (within 12 seconds), the yarn enters the yarn-laying hole, and winding begins, marking the start of normal operation. The other turntable can be in normal yarn-drawing mode or in a stopped state.

[0050] Dual-head winding: In normal continuous production, two turntables and two winding heads rotate simultaneously. The winding mechanism manually guides the raw yarn to the automatic winding device (or manually). Through the rotation of the lower turntable, one winding head on the lower turntable guides the yarn to the winding spool. At this time, the upper turntable rotates, and one winding head on the upper turntable guides the yarn to the winding spool. As the two sets of yarn-laying mechanisms reach their positions in stages (less than or equal to 12 seconds), the yarn enters the yarn-laying hole and the winding begins. At this time, normal operation begins and the winding starts, realizing the synchronous winding of the two winding heads.

[0051] Head reversal: During the winding process, when the yarn bobbin on one running head is full, the system automatically starts the turntable. The yarn pushing mechanism pushes the raw yarn to the winding disc. Through the rotation of the turntable, the full bobbin head rotates to the empty head position, and the empty head rotates to the full bobbin head position to start normal operation. The raw yarn can be replaced through the winding discs on the two heads. After the replacement is completed, the yarn pushing mechanism returns to its original position, the raw yarn enters the designated position of the head, and the yarn laying mechanism enters the position in steps (less than or equal to 12 seconds). The yarn enters the yarn laying hole, thus realizing uninterrupted continuous production. During the head reversal process, the two heads can be reversed independently, and the reversal work is independent.

[0052] Winding: The combined complete glass fiber filaments are finally wound into a yarn bobbin of a specified shape and weight under constant tension.

[0053] II. Core Equipment and Innovative Control Methods The drawing machine used in this process is a four-head, dual-rotor system, with two heads mounted on one rotor. The two rotors can operate simultaneously or independently without interference, yet they can work in tandem. Within each rotor system, one head is in the rotating working state, while the other is used to unload the wound yarn. The core innovation of this structure lies in: Dual-head independent speed control: The support shafts of the two heads can operate at different speeds.

[0054] Two sets of bundlers: A first bundler set and a second bundler set are provided between the wire drawing machine and the stencil.

[0055] See Figure 6 The first clusterer group has multiple points, such as a1, b1, c1, d1, e1, f1.

[0056] The second clusterer group, corresponding to the support shaft of the machine head, also has points a2, b2, c2, d2, e2, and f2. Among them, a2, b2, and c2 correspond to the support shaft of the first speed machine head, and d2, e2, and f2 correspond to the support shaft of the second speed machine head.

[0057] Support shaft specifications: The one machine head (support shaft) can be selected with 3 to 6 cylinders, and can independently produce 2 varieties of numbers.

[0058] III. Supporting Debugging Methods To maximize the above advantages, this invention also proposes a set of efficient debugging methods: Pre-debugging: First, the yarn is allocated according to the default one-to-one path, namely: a1→a2, b1→b2, c1→c2, d1→d2, e1→e2, f1→f2.

[0059] Feedback adjustment: Collect linear density data of yarns produced from each path.

[0060] For example, the test found that the yarn in the a1→a2 and c1→c2 paths was too thick (350tex), the yarn in the e1→e2 and f1→f2 paths was too thin (250tex), while the yarn in the b1→b2 and d1→d2 paths was acceptable.

[0061] Optimize and redistribute the yarns: adjust the paths of coarser yarns to the lower-speed machine head (support shaft), and adjust the paths of finer yarns to the higher-speed machine head (support shaft). Specifically, the adjustments can be: a1→e2 (high speed), c1→f2 (high speed); e1→a2 (low speed), f1→c2 (low speed). This cross-distribution utilizes the speed difference to compensate for the flow rate difference, concentrating the linear density of all yarns towards the target value.

[0062] In summary, this invention provides a wire drawing machine take-up structure and a wire drawing process, including: frame; A winding head is movably mounted on the frame. The winding head has a central area around which yarn is wound. The winding head is driven to rotate by a rotary motor. The winding head includes several ring-shaped tension bars and a support plate supporting the tension bars. When winding glass fiber yarn, the rotary motor drives the winding head to rotate, causing the yarn to wind onto the tension bars. A first driving component is mounted on the frame and has a driving end that reciprocates along the direction extending around the center. The first driving component can be a linear motor, with its base fixedly mounted on the frame. The extension and retraction direction of its output rod is parallel to the direction extending around the center. A guide component is movably mounted on the driving end and has an internal drawing hole for the yarn to pass through. A cutter is provided on one side of the drawing hole. The diameter of the drawing hole is set as needed. After the yarn is pulled through the drawing hole, it is stretched to the required diameter due to resistance, thus achieving the drawing process.

[0063] The guide component has multiple drawing holes of different diameters to accommodate yarns of different diameters.

[0064] As the first driving component drives the guide component to reciprocate, the yarn to be drawn is evenly wound onto the expansion strip along the extension direction around the center.

[0065] The spraying component, installed at the drive end, includes a nozzle with its output end facing the winding machine head and a sensing component connected to the nozzle for sensing water pressure. The nozzle sprays water to cool the yarn directly onto the yarn bundle at the winding machine head. The cooling serves two purposes: firstly, to reduce the yarn's adhesion and prevent the wound yarn from sticking together; secondly, to reduce the yarn's plasticity and increase its tensile strength.

[0066] When the sensing component detects that the water pressure is below a predetermined threshold, it forces the yarn passing through the drawing hole to tend towards the cutter, thus cutting the yarn and preventing the tangled yarn from sticking together and affecting subsequent unwinding. This invention can adjust the deflection angle of the guide component according to the water pressure. When the water flow is insufficient and the deflection angle is large enough, the yarn will contact the blade, achieving the cutting process. This ensures the equipment has an emergency execution component in case of water flow obstruction, guaranteeing high-quality output.

[0067] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.

Bundling and winding: Bundling: Hundreds of monofilaments drawn from all the micropores of the same sprue are coated with a sizing agent as they pass through the bundler; when the yarn bobbin on one head is full, the system automatically guides the raw yarn to another head to achieve uninterrupted continuous production; in current drawing machines, only one head is producing while the other head is waiting, ensuring uninterrupted production unless some monofilaments of the glass fiber itself break, in which case the machine will be forced to stop. Getting on the vehicle: This is the initial step in winding.
