Description

Technical Field

[0001] This invention relates to the field of wire drawing machines, and more particularly to a wire drawing head for a wire drawing machine 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] In the current unloading process of the drawing machine, after the winding head winds the glass fiber into a ball, the diameter of the winding head is reduced, so that a gap is formed between the inner circle of the ball and the expansion strip for easy movement. Then, the pushing mechanism pushes the ball off the fixed column of the machine head.

[0004] However, during the feeding process, the upper inner edge of the yarn bundle still contacts the stretcher under the action of gravity. As the yarn bundle moves, resistance inevitably occurs between the inner edge of the yarn bundle and the stretcher. This resistance pulls on the yarn bundle, causing the yarn to loosen at the contact point.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0006] To address the aforementioned shortcomings, the present invention aims to provide a drawing head for a drawing machine and the drawing process thereof, which can optimize the pushing structure of the drawing machine so that the inner edge of the yarn ball and the yarn strip work without contact, thereby avoiding the scattering of the inner edge of the yarn ball.

[0007] To achieve the above objectives, the present invention provides a wire drawing head for a wire drawing machine, comprising: a frame; The winding component, rotatably mounted on the frame, includes multiple tension strips distributed around a first direction. Each tension strip can switch between two states: approaching or moving away from the first direction, thereby changing the diameter of the support space. The yarn guide component includes a yarn guide head that reciprocates along the first direction, and the yarn guide head has a yarn guide hole for the yarn to pass through. The unloading component includes a first push plate that reciprocates along the first direction. During unloading, the first push plate squeezes the yarn bundle and moves it in the first direction. The first push plate is provided with a lifting component for supporting the lower end of the yarn bundle during unloading, so that there is a gap between the inner edge of the yarn bundle and the tension strip.

[0008] According to the wire drawing head of the wire drawing machine of the present invention, the first push plate is moved by being driven by the first driving component; the first driving component is mounted on the frame, and the first push plate is mounted on the output shaft of the first driving component.

[0009] According to the present invention, in the wire drawing head of the wire drawing machine, the first push plate rotates around the output shaft of the first drive component to enter the working state; the first push plate is connected to an outer sleeve, which is rotatably sleeved on the output shaft of the first drive component and connected to a rotary drive motor and driven by it to rotate; the rotary drive motor is equipped with a movable seat, which is connected to the output shaft of the first drive component.

[0010] According to the present invention, the first push plate of the wire drawing machine is an arc-shaped structure and rotates downward and upward to enter the working state.

[0011] According to the drawing head of the drawing machine of the present invention, the unloading component further includes a second push plate that reciprocates along the first direction of extension; during unloading, the second push plate squeezes the yarn ball and moves synchronously and in the same direction as the first push plate.

[0012] According to the wire drawing head of the wire drawing machine of the present invention, the second push plate is also an arc-shaped structure and is symmetrically arranged with respect to the second push plate; the driving structure of the second push plate is the same as the driving structure of the first push plate.

[0013] According to the drawing head of the drawing machine of the present invention, the second push plate is rotatably mounted with a lever, the end of which pushes the upper part of the yarn ball to move away from the first direction so as to keep the yarn ball in a vertical state.

[0014] According to the drawing head of the drawing machine of the present invention, the other end of the lever is provided with a push plate, which is used to push the upper part of the yarn ball to move in a first direction after the inner edge of the yarn ball is separated from the tensioning sliver.

[0015] A 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.

[0016] This invention provides a drawing head for a wire drawing machine, comprising: a frame; and a winding component rotatably mounted on the frame, which includes multiple tension strips distributed around a first direction. Each tension strip can switch between two states: approaching or moving away from the first direction, thereby changing the diameter of a support space. The multiple tension strips collectively support the support space. During winding, the yarn is wound within the support space to form a columnar yarn bundle. During operation, the tension strips move outward, forming a larger diameter support space, and the winding component rotates to wind the yarn onto the tension strips. During unloading, the tension strips move inward, reducing the support space. During this movement, the tension strips disengage from the inner edge of the yarn bundle, reducing the tension of the inner edge and facilitating the unwinding of the yarn bundle from the winding component. The yarn guide component includes a yarn guide head that reciprocates along a first extending direction, and the yarn guide head has a yarn guide hole for the yarn to pass through; the yarn guide head is driven to move by a second driving component, which is mounted on the frame and whose output end is connected to the yarn guide head; during the winding operation, in conjunction with the rotation of the winding component, the second driving component drives the yarn guide head to reciprocate along the first extending direction to evenly wind the yarn onto the tension strip. The unloading component includes a first pusher plate that reciprocates along a first extending direction. During unloading, the first pusher plate squeezes the yarn bundle and moves it in the first direction. Once the yarn bundle is completely detached from the tensioner support, it falls naturally. The first pusher plate is equipped with a lifting component to support the lower end of the yarn bundle during unloading, creating a gap between the inner edge of the yarn bundle and the tensioner. The lifting component supports the yarn bundle upwards, ensuring that the inner edge of the yarn bundle is always separated from the tensioner, i.e., in a non-contact state. In this state, non-contact separation of the yarn bundle from the tensioner is achieved, preventing resistance between the inner edge of the yarn bundle and the tensioner, which could lead to yarn loosening at the contact point. This invention optimizes the pushing structure of the drawing machine, enabling non-contact separation between the inner edge of the yarn bundle and the tensioner, thus preventing the inner edge of the yarn bundle from becoming scattered.

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.

[0022] See Figure 1 This invention provides a wire drawing head for a wire drawing machine and the wire drawing process used therein. The wire drawing head of the wire drawing machine includes: Rack 1; The winding component 2 is rotatably mounted on the frame 1. It includes multiple tension bars 21 distributed around a first direction. Each tension bar 21 can switch between two states: close to or far from the first direction, so as to change the diameter of the support space. The multiple tension bars 21 together support the support space. During the winding process, the yarn is wound in the support space to form a yarn ball with a columnar structure. During operation, the tension bar 21 moves outward, forming a large-diameter support space. The winding component 2 rotates to wind the yarn onto the tension bar 21. During unloading, the tension bar 21 moves inward, reducing the support space. During this movement, the tension bar 21 separates from the inner edge of the yarn ball, reducing the tension of the inner edge and facilitating the unwinding of the yarn ball from the winding component 2.

[0023] The specific structure of the stretching strip 21 is referenced from Chinese patent document CN113185116A, entitled "Structure of a High-Speed ​​Five-Ply Fiber Cotton Yarn Drawing Machine". Several stretching strips 21 are mounted on a drive disc, and the rotation of the entire winding component 2 is further achieved by the drive motor.

[0024] The yarn guide component includes a yarn guide head 41 that reciprocates along a first direction of extension, and the yarn guide head has a yarn guide hole for yarn to pass through; a second drive component is mounted on the frame 1, and its output end is connected to the yarn guide head 41. During the winding operation, in conjunction with the rotation of the winding component 2, the second driving component drives the guide head 41 to reciprocate along the first direction of extension, so as to evenly wind the yarn onto the expansion strip 21.

[0025] See Figure 1 , Figure 2 and Figure 3 The unloading component includes a first pusher plate 3 that reciprocates along a first direction. During unloading, the first pusher plate 3 squeezes the yarn bundle. Figure 5 The yarn ball moves in the first direction from position A. After the yarn ball is completely detached from the support of the tension strip 21, the yarn ball falls naturally. The first push plate is provided with a lifting component 31, which is used to support the lower end of the yarn ball during unloading, so that there is a gap between the inner edge of the yarn ball and the tension strip 21. The lifting component 31 is used to lift and support the yarn ball upward, so that there is a gap between the inner edge of the yarn ball and the tension strip 21, that is, in a non-contact state. In this state, the non-contact detachment of the yarn ball from the tension strip 21 is achieved, avoiding the resistance between the inner edge of the yarn ball and the tension strip, which would cause the yarn to loosen at the contact position of the yarn ball.

[0026] The first push plate 3 rotates around the output shaft of the first drive component to enter the working state. By rotating the first push plate 3, the working state and the non-working state can be switched. The first push plate 3 has an arc-shaped structure, which can increase the contact area between the first push plate 3 and the yarn ball, disperse the pushing force, and optimize the pushing effect. At the same time, it rotates from the bottom of the winding component 2 to enter the working state, which can drive the lifting component 31 to enter the working state, that is, apply an upward lifting support force.

[0027] Specifically, in this embodiment, during unloading, the first push plate 3 enters the working state by rotating inwards, in which the inner arc surface of the first push plate 3 corresponds to the winding component 2. During the winding process, the first push plate 3 exits the working state by rotating outwards in the opposite direction. Specifically, in the rotating structure, the first push plate 3 is connected to an outer sleeve 31. The outer sleeve 31 is rotatably fitted onto the output shaft of the first driving component and connected to a rotation drive motor, which drives the first push plate 3 to rotate. The rotation drive motor is connected to the outer sleeve 31 via a gear set. The rotation drive motor is mounted on a movable base, which is connected to the output shaft of the first driving component. The rotation drive motor drives the first push plate 3 to rotate to switch states, while the first driving component drives the first push plate 3 to push materials.

[0028] See Figure 1 , Figure 2 and Figure 4 To ensure uniform force distribution during yarn ball movement and prevent yarn ball tilting, which could lead to localized contact between the inner edge and the expansion strip 21 and cause the aforementioned yarn scattering due to resistance, the unloading component further includes a second push plate 6 that reciprocates along the first direction. During unloading, the second push plate 6 compresses the yarn ball and moves synchronously and in the same direction as the first push plate 3, achieving the pushing operation. The second push plate 6 also has an arc-shaped structure and is symmetrically arranged with other push plates. The driving structure of the second push plate 6 is the same as that of the first push plate 3. As shown in the figure, the second push plate 6 is an upper arc plate, and the first push plate 3 is a lower arc plate, together forming an enclosed or semi-enclosed structure, which allows for more uniform force application to the yarn ball during the pushing operation.

[0029] See Figure 5 Preferably, in order to further prevent the yarn ball from tilting, the second push plate 6 is rotatably equipped with a lever 7. The end of the lever 7 pushes the upper part of the yarn ball away from the first direction, generating a pull force to keep the yarn ball in a vertical state.

[0030] After the inner edge of the yarn ball detaches from the tension bar 21, in order to ensure that the yarn ball falls from the lifting component 31, the other end of the lever 7 is provided with a push plate 8, which is used to push the upper part of the yarn ball to move in the first direction after the inner edge of the yarn ball detaches from the tension bar. The push plate 8 rotates to apply an outward pushing force to the upper end of the yarn ball, causing the yarn ball to tilt again and fall out of the device.

[0031] The lever 7 and the push plate 8 are an integral structure, rotatably mounted on the second push plate 6, and rotated by a drive rack. A drive wheel is provided at the connection between the lever 7 and the push plate 8, and the drive wheel meshes with the drive rack 9. When the second push plate 6 rotates to the working state, the end of the drive rack contacts the expansion bar 21 and is pressed to generate transmission, thereby driving the lever 7 to retract.

[0032] When the second push plate 6 rotates to the non-working state, the drive rack loses the pressure of the expansion bar 21 and resets under the action of the spring (not shown in the figure), thereby driving the push plate 8 to advance.

[0033] In addition, this invention also discloses a fiber drawing process. This invention provides an advanced glass fiber drawing process that significantly improves product quality and production efficiency through innovative equipment layout (two sets of automatic reversing fiber drawing combinations, a total of 4 heads; one set consists of 2 heads, with 1 head working and 1 head waiting) and dynamic control method.

[0034] 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.

[0035] 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).

[0036] 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.

[0037] 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.

[0038] 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.

[0039] Getting on the vehicle: This is the initial step in winding.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] Winding: The combined complete glass fiber filaments are finally wound into a yarn bobbin of a specified shape and weight under constant tension.

[0045] 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.

[0046] Two sets of bundlers: A first bundler set and a second bundler set are provided between the wire drawing machine and the stencil.

[0047] See Figure 6 The first clusterer group has multiple points, such as a1, b1, c1, d1, e1, f1.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] Feedback adjustment: Collect linear density data of yarns produced from each path.

[0052] 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.

[0053] 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.

[0054] In summary, this invention provides a drawing head for a wire drawing machine, comprising: a frame; and a winding component rotatably mounted on the frame, which includes multiple tension strips distributed around a first direction. Each tension strip can switch between two states: approaching or moving away from the first direction, thereby changing the diameter of the support space. The multiple tension strips collectively support the support space. During the winding process, the yarn is wound within the support space to form a columnar yarn ball. During operation, the tension strips move outward, forming a large-diameter support space, and the winding component rotates to wind the yarn onto the tension strips. During unloading, the tension strips move inward, reducing the support space. During this movement, the tension strips disengage from the inner edge of the yarn ball, reducing the tension of the inner edge and facilitating the unwinding of the yarn ball from the winding component. The yarn guide component includes a yarn guide head that reciprocates along a first extending direction, and the yarn guide head has a yarn guide hole for the yarn to pass through; the yarn guide head is driven to move by a second driving component, which is mounted on the frame and whose output end is connected to the yarn guide head; during the winding operation, in conjunction with the rotation of the winding component, the second driving component drives the yarn guide head to reciprocate along the first extending direction to evenly wind the yarn onto the tension strip. The unloading component includes a first pusher plate that reciprocates along a first extending direction. During unloading, the first pusher plate squeezes the yarn bundle and moves it in the first direction. Once the yarn bundle is completely detached from the tensioner support, it falls naturally. The first pusher plate is equipped with a lifting component to support the lower end of the yarn bundle during unloading, creating a gap between the inner edge of the yarn bundle and the tensioner. The lifting component supports the yarn bundle upwards, ensuring that the inner edge of the yarn bundle is always separated from the tensioner, i.e., in a non-contact state. In this state, non-contact separation of the yarn bundle from the tensioner is achieved, preventing resistance between the inner edge of the yarn bundle and the tensioner, which could lead to yarn loosening at the contact point. This invention optimizes the pushing structure of the drawing machine, enabling non-contact separation between the inner edge of the yarn bundle and the tensioner, thus preventing the inner edge of the yarn bundle from becoming scattered.

[0055] 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.
