Description

Technical Field

[0001] This invention relates to the field of polyester fiber technology, specifically to a TMT-V type texturing machine baffle plate and anti-winding method for producing blended yarns. Background Technology

[0002] In today's rapidly evolving technological landscape, the polyester texturing yarn industry is experiencing robust growth. Production efficiency has significantly improved, product quality and performance have been substantially optimized, and differentiated varieties are becoming increasingly diverse, fully meeting varied consumer demands. However, with this booming market, competition is also intensifying. While polyester filament supply is rapidly expanding, demand growth is relatively slow, with the increase in texturing machines far exceeding the increase in downstream weaving, leading to a gradual slowdown in demand growth. Furthermore, most of the new capacity is concentrated in a few leading companies, further exacerbating market competition and placing unprecedented competitive pressure on enterprises. Against this industry backdrop, our company has introduced the advanced Japanese fully automatic TMT-V type texturing machine and innovatively modified it. In particular, by adding a zero-roller to the first roller, it can be used to produce blended yarns, successfully achieving product differentiation and delivering superior performance compared to general varieties.

[0003] However, in the production process of blended yarns, the yarn bundle needs to pass through multiple rollers, guides, heating boxes, false twisters, and other components. Due to the complex influence of factors such as speed matching between components, tension changes, and the characteristics of the yarn bundle itself, the yarn flowing out of the yarn tube on the raw yarn frame inevitably has the problem of breakage. Since the zero roller is installed on a single roller, once a yarn bundle breaks between the raw yarn tube and the zero roller, the yarn bundle easily gets tangled on the equipment components, causing frequent machine stoppages after a breakage. The roller guard is also easily damaged. This not only leads to production interruptions and reduces machine utilization, but the frequent cleaning of the tangled yarn also increases the labor intensity of workers, significantly increasing the workload of operators and maintenance personnel, reducing the yield of high-quality products, and increasing raw material waste. Worse still, roller breakage and stoppages directly affect output, while also increasing maintenance costs and workload. Currently, although some TMT "V" type machines have adopted certain anti-winding measures in their design, the existing anti-winding measures are not satisfactory in the actual production of mixed fiber yarns, especially mixed fiber yarns with special specifications or high performance requirements, and cannot meet production needs. Summary of the Invention

[0004] In order to solve one or more technical problems existing in the prior art, one of the objectives of this application is to provide a TMT-V type texturing machine baffle plate for producing mixed fiber yarn, which can effectively reduce the occurrence of machine stoppage and roller cover breakage, thereby avoiding negative impacts on production efficiency and product quality, while reducing maintenance costs.

[0005] The second objective of this application is to provide a method for preventing tangling in a TMT-V type texturing machine used for producing blended yarns. This eliminates the need to frequently deal with the troublesome tangling cleaning work, significantly reducing the workload. At the same time, the machine no longer has to stop frequently due to tangling problems, greatly increasing the running time and significantly improving production efficiency. The stable operation of the equipment ensures the continuity of the production process, and both product output and quality are effectively guaranteed.

[0006] To address the aforementioned technical problems, one of the objectives of this application is achieved through the following technical solution: A TMT-V type texturing machine baffle plate for producing blended yarns includes a stainless steel plate, a first bent edge and a second bent edge on both sides of the stainless steel plate, and at least two elongated pull grooves on the stainless steel plate. The stainless steel plate is mounted on a roller guard plate through the pull grooves.

[0007] Preferably, the first bent edge is bent along the curvature of the roller guard plate.

[0008] Preferably, the second bent edge is bent along the direction of the filament bundle, and the bent second bent edge is arranged parallel to the filament bundle.

[0009] Preferably, the bending angle of the first bending edge is 120°, and the bending angle of the second bending edge is 15°.

[0010] Preferably, the stainless steel plate is also provided with cylinders at both ends.

[0011] The second objective of this application is achieved through the following technical solution: A method for preventing tangling in a TMT-V type texturing machine used for producing blended yarns, the method comprising: S1. Fabrication of the wire baffle: The wire baffle is made from stainless steel sheet; S2. Material preparation: Prepare an electronic vernier caliper with an accuracy of 0.1mm, a 6.5mm twist drill bit, a matching bench drill or hand drill, 6mm hex socket screws, nuts, an adjustable wrench, a rubber hammer, a marker pen, and a clean cloth. Ensure that the tools are intact and the accuracy meets the installation requirements. S3. Inspect the processed wire baffle: ensure that its dimensions are accurate, its surface is smooth, its bending angle is precise, and the position and diameter of the screw holes meet the design requirements. S4. Install the thread stop plate: Clean the surface of the guard plate on the roller of the machine with a clean cloth. Check the guard plate for deformation or damage. If there is a problem, it needs to be repaired or replaced in advance. Ensure that the installation base is firm and reliable. Drill holes at the corresponding positions on the guard plate, and then use 6mm hex screws to fix the thread stop plate to the guard plate through the pull-out groove. Ensure that the installed thread stop plate can be smoothly pulled out and pushed in along the pull-out groove. S5. Use wire baffle: When producing regular products, push the wire baffle in and tighten it again with screws to ensure that it does not affect the processing of regular products; when processing mixed fiber yarns, pull out the wire baffle and tighten it with the matching screws.

[0012] The third objective of this application is achieved using the following technical solution: A method for preventing tangling in a TMT-V type texturing machine used for producing blended yarns, the method comprising: S1. Fabrication of the wire baffle: The wire baffle is made from stainless steel sheet. S2. Material preparation: Prepare an electronic vernier caliper with an accuracy of 0.1mm, a 6.5mm twist drill bit, a matching bench drill or hand drill, 6mm hex socket screws, nuts, an adjustable wrench, a rubber hammer, a marker pen, and a clean cloth. Ensure that the tools are intact and the accuracy meets the installation requirements. S3. Inspect the processed wire baffle: ensure that its dimensions are accurate, its surface is smooth, its bending angle is precise, and the position and diameter of the screw holes meet the design requirements. S4. Install the wire baffle: Clean the surface of the guard plate on the roller of the machine with a clean cloth. Check the guard plate for deformation or damage. If there are any problems, repair or replace it in advance. Ensure that the installation base is firm and reliable. Drill holes at the corresponding positions on the guard plate. Then, use a 6mm pin or screw to install the wire baffle onto the guard plate through the pull-out groove. Install the cylinder onto the TMT-V type texturing frame. Ensure that the wire baffle can be smoothly pushed out and pushed forward along the pull-out groove after installation by the cylinder control. S5. Use wire baffle: When producing regular products, push the wire baffle in and tighten it again with screws to ensure that it does not affect the processing of regular products; when processing mixed fiber yarns, pull out the wire baffle and tighten it with the matching screws.

[0013] Preferably, the preparation steps of the wire baffle include: A1. Prepare a stainless steel plate that is 1720mm long, 100mm wide, and 0.5mm thick. Ensure that the material meets the requirements for strength and durability, and that the surface is flat and free of defects, obvious scratches, dents, or deformation. A2. Initial Dimensioning: Based on the machine tool dimensions, precisely reserve a length of 30mm at each end of the stainless steel plate; A3. Pull-out slot positioning: The first hole is machined in the middle of the stainless steel plate, and the second hole is machined with the length reserved at both ends of A2 as the center. The diameter of each hole is 6.5mm. A4. Milling operation of the pull groove: Use a 6.5mm milling cutter to insert into the hole in step A3 to perform milling operation, and mill out a pull groove with a length of 82.7mm; A5. Determine the center length: Measure and confirm the center distance between two adjacent pull-out slots as 830mm; A6. Bending process: Bend both sides of the board separately, bending one side to 120° and the other side to 15°.

[0014] Preferably, in step S5, when processing the mixed fiber filaments, the distance between the first bent edge of the baffle plate after it is pulled out and the filament bundle is 5~8cm.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: First, the wire baffle is made entirely of stainless steel, which not only reduces manufacturing costs but also ensures that the device can operate stably in a long-term, high-intensity production environment without the need for frequent replacement or maintenance.

[0016] Secondly, by adding a retractable wire-blocking plate to the roller guard plate, normal filament production can be guaranteed, and the problem of raw filaments quickly wrapping around the roller after falling off during the production of blended filaments, due to breakage at the end or in the middle of the process, can be solved. This makes filament cleaning and splicing simple and efficient, eliminating the need for frequent intervention by maintenance and electromechanical personnel.

[0017] Third, the machine no longer frequently stops due to wire winding problems, significantly increasing operating time and improving production efficiency. The stable operation of the equipment ensures the continuity of the production process, effectively guaranteeing both product output and quality.

[0018] Fourth, due to the significant reduction in equipment wear caused by wire winding, the number of repairs and the difficulty of repairs are reduced, and the consumption of various maintenance consumables also decreases, greatly reducing the company's production and operating costs.

[0019] Figure 1 This is a schematic diagram of the wire baffle plate in this invention; Figure 2 Top view of the wire baffle plate in this invention when cylinders are installed at both ends; In the diagram: 1. First bend; 2. Stainless steel sheet; 3. Pull-out groove; 4. Second bend; 5. Cylinder. Detailed Implementation

[0020] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0022] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0023] Example 1: As Figure 1 As shown, a TMT-V type texturing machine baffle plate for producing blended yarn includes a stainless steel plate 2, a first bent edge 1 and a second bent edge 4 on both sides of the stainless steel plate 2, and at least two elongated pull grooves 3 on the stainless steel plate 2. The stainless steel plate 2 is mounted on a roller guard plate through the pull grooves 3. The first bent edge 1 is bent along the arc of the roller guard plate. The second bent edge 4 is bent along the direction of the yarn bundle flow.

[0024] The wire-blocking plate is made of stainless steel sheet 2, which is sturdy and durable. This not only reduces manufacturing costs but also ensures that the device can operate stably in long-term, high-intensity production environments without frequent replacements or maintenance. This simple and durable structure makes the device highly valuable for widespread adoption. Once popularized in the industry, it is expected to drive efficiency improvements and cost optimization in the entire polyester texturing yarn production industry, contributing to the healthy and sustainable development of the industry. Specifically, because the first roller guard plate itself has a certain tilt angle, the first bending edge 1 bends along the arc of the first roller guard plate, which allows the wire-blocking plate to act as a limit during storage. This allows operators to visually determine whether the wire-blocking plate has been fully inserted after being pushed in, preventing it from bending due to excessive pushing. The second bending edge 4 prevents the yarn from being quickly cut when in contact with it and also blocks yarn that falls onto the wire-blocking plate, preventing the yarn from sliding outwards along the surface of the wire-blocking plate.

[0025] A further improvement is made whereby the bending angle of the first bending edge 1 is 120° and the bending angle of the second bending edge is 15°.

[0026] The bending angle of the first bending edge 1 is 120°, which is consistent with the bending angle of the guard plate. After being pushed in, the first bending edge 1 fits the guard plate better. The bending angle of the second bending edge is 15°. The second bending edge after bending can not only block the falling yarn bundle, but also make it wider. When the yarn bundle of a roller comes into contact with it in the early stage of stretching, it will not be cut by the yarn baffle. At the same time, it also makes it easier for the operator to drive the yarn baffle.

[0027] Further improvements include, such as Figure 2 As shown, the stainless steel plate 2 is also equipped with cylinders 5 at both ends. The stainless steel plate 2 is connected to the frame of the TMT-V type texturing machine through the cylinders 5. The cylinders 5 can control the extension and retraction of the stainless steel plate 2, so that the wire baffle can be quickly pulled out when producing mixed fiber yarn.

[0028] Example 2: A method for preventing tangling in a TMT-V type texturing machine used for producing blended yarns, the method comprising: S1. Fabrication of the wire baffle: The wire baffle is fabricated from stainless steel sheet 2; S2. Material preparation: Prepare an electronic vernier caliper with an accuracy of 0.1mm, a 6.5mm twist drill bit, a matching bench drill or hand drill, 6mm hex socket screws, nuts, an adjustable wrench, a rubber hammer, a marker pen, and a clean cloth. Ensure that the tools are intact and the accuracy meets the installation requirements. S3. Inspect the processed wire baffle: ensure that its dimensions are accurate, its surface is smooth, its bending angle is precise, and the position and diameter of the screw holes meet the design requirements. S4. Install the thread stop plate: Clean the surface of the guard plate on the first roller of the machine with a clean cloth. Check the guard plate for deformation or damage. If any problems are found, repair or replace it in advance. Ensure that the installation base is firm and reliable. Drill holes at the corresponding positions on the guard plate, and then use 6mm Allen screws to fix the thread stop plate to the guard plate through the pull-out groove 3. Ensure that the installed thread stop plate can be smoothly pulled out and pushed in along the pull-out groove 3. When drilling holes on the guard plate, carefully measure the dimensions of the pull-out groove 3 on the thread stop plate with an electronic vernier caliper and record the data accurately. Based on the measured data, use a marker to mark the corresponding positions on the guard plate on the first roller of the machine, marking 3 drilling points to ensure accurate positioning. Fix the guard plate on the bench drill table (if using a hand drill, ensure the guard plate is stable). Select a 6.5mm twist drill bit and start the bench drill (or hand drill) to perform the drilling operation. Keep the drill bit vertical during drilling and control the feed speed to avoid slanted holes or hole diameter deviations. After drilling, clean the metal debris from the hole.

[0029] Align the machined thread stop plate with the pre-drilled holes on the protective plate, and slowly bring it closer until the screw holes on the thread stop plate are completely aligned with the holes on the protective plate. Take a 6mm Allen screw and gently screw it into the screw hole with an Allen screwdriver, being careful not to fully tighten it; this is just to initially secure the thread stop plate. Gently pull the thread stop plate by hand to test its smoothness of pulling out and pushing in. If you feel any resistance, you can gently tap the thread stop plate with a rubber mallet to fine-tune its position; or use an adjustable wrench to carefully adjust the tightness of the screw until the thread stop plate can be pulled out and pushed in smoothly.

[0030] After confirming that the wire stop plate can be pulled out and pushed in without any abnormalities, use an internal triangular screwdriver to gradually tighten the 6mm internal triangular screws to ensure that the wire stop plate is firmly fixed to the guard plate. Apply force evenly during tightening to avoid tilting or deformation of the wire stop plate due to uneven force. Check the installation of the wire stop plate again by manually operating it several times to confirm its stability and smoothness. If everything is normal, proceed to the installation and adjustment of the next wire stop plate, repeating the above steps until the anti-winding device for the entire machine is installed.

[0031] S5. Use wire baffle: When producing regular products, push the wire baffle in and tighten it again with screws to ensure that it does not affect the processing of regular products; when processing mixed fiber yarns, pull out the wire baffle and tighten it with the matching screws.

[0032] Because the existing TMT-V type texturing machine lacks an anti-winding device when producing mixed fibers, the raw yarn entering the zero roller is prone to breakage or overshooting, causing the yarn bundle to fall directly downwards. This leads to machine stoppages and roller guard plate breakage, reducing machine utilization, significantly increasing the workload of operators and maintenance personnel, lowering the yield rate of high-quality products, and increasing raw material waste. To reduce machine stoppages and roller guard plate breakage, avoid negative impacts on production efficiency and product quality, and lower maintenance costs, a yarn guide plate is installed on the first roller guard plate of the TMT-V type texturing machine. In actual use, the yarn guide plate is installed on the first roller guard plate via a pull-out groove 3, positioning it between the zero and first rollers. When producing ordinary yarn bundles, the yarn guide plate is pushed inwards and fixed inside the guard plate, without affecting the yarn bundle trajectory. When producing blended filaments, the baffle plate is pulled outward along the pull-out groove 3 and tightened with matching screws. During installation, ensure the screws are tightened to a moderate degree to guarantee the baffle plate is stable and does not wobble, so that the outer second bend edge is close to the filament bundle passing through the first roller. When a filament bundle falls off the zero roller, the baffle plate can effectively block the falling filament, preventing it from wrapping around the first roller, achieving multiple uses in one machine and avoiding the phenomenon of broken ends and tangled filaments.

[0033] Since the successful installation of this wire guide plate, significant and positive changes have occurred in the production process. Previously, end-of-line and mid-line breakage were common problems. When this happened, the raw filament would fall without obstruction and quickly become entangled on the rollers. This required employees to immediately stop their work and invest considerable time and effort in cleaning the entangled filaments. Maintenance personnel also had to frequently intervene to inspect and repair equipment potentially damaged by the entanglement, resulting in extremely high workloads. Simultaneously, frequent machine downtime due to entanglement problems led to a severe decline in production efficiency and a continuous increase in maintenance costs. After the system was implemented, the situation was fundamentally reversed. When end-of-line or mid-line breakage occurs again, the fallen raw filament is firmly stopped by the carefully designed wire guide plate. In the process of processing mixed fiber yarn, the distance between the first bent edge of the yarn baffle after it is pulled out and the yarn bundle is 5-8cm, and the distance between the yarn baffle and the yarn bundle is 5-8cm. The special shape and installation position of the yarn baffle enable it to accurately intercept falling yarn, thus eliminating the occurrence of yarn entanglement rollers from the root.

[0034] A further improvement is made to the method where the wire-blocking plate is prepared by: A1. Prepare a stainless steel plate 2 with a length of 1720mm, a width of 100mm, and a thickness of 0.5mm. Ensure that the material meets the requirements for strength and durability, and that the surface is flat and free of defects, obvious scratches, dents, or deformation; so as to provide a good base for subsequent processing. A2. Initial Dimensioning: According to the machine tool dimensions, precisely reserve a length of 30mm at each end of the stainless steel plate 2. This step requires the use of precise measuring tools, such as steel rulers or vernier calipers, to ensure that the error of the reserved length is controlled within a very small range, laying the foundation for the accuracy of subsequent processing and installation. A3. Positioning of pull-out groove 3: The first hole is machined in the middle of the stainless steel plate 2, and the second hole is machined with the length reserved at both ends of A2 as the center. The diameter of each hole is 6.5mm. In this process, stainless steel sheet 2 is divided into two equal parts by the first hole, and a second hole is machined centered on the length reserved at both ends of A2. Professional measuring and positioning tools, such as right-angle rulers and positioning clamps, are used to ensure the accuracy of the division. Three holes with a diameter of 6.5mm are evenly drilled in each divided area. During drilling, the force and speed must be carefully controlled to prevent deformation of the sheet due to uneven stress, ensuring the positional accuracy and standard diameter of the holes. A4. Milling operation of the pull groove 3: Use a 6.5mm milling cutter to insert into the hole in step A3 to perform milling operation, and mill out the pull groove 3 with a length of 82.7mm; Starting with a 6.5mm hole, use a 6.5mm milling cutter to mill the groove. When milling the groove, the milling cutter's depth, feed rate and other parameters must be strictly set and controlled to ensure that the length of each pull groove 3 is consistent and parallel, and that the groove wall of the pull groove 3 is smooth and flat, without burrs or chipping, so as to meet the performance requirements and avoid jamming during the pulling of the wire stop plate. A5. Determine the center length: Measure and confirm the center distance between two adjacent pull-out slots as 830mm; To ensure the accuracy of this critical dimension, high-precision measuring tools were used to repeatedly check the dimensions to ensure that the entire wire baffle plate meets the design standards. A6. Bending process: Bending operation is performed on both sides of the board, one side is bent to 120° and the other side is bent to 15°. Professional bending equipment is used in the bending process, and precise angle measuring instruments, such as angle gauges, are used to monitor and adjust the bending angle in real time to ensure that the accuracy required by the design is achieved and to ensure that the shape and function of the wire baffle meet the expectations.

[0035] The positive impact of this innovative improvement is multifaceted. For employees, the workload is significantly reduced, eliminating the need to frequently deal with troublesome wire winding cleanup tasks. This allows them to focus more on other critical production processes, resulting in a significant improvement in work efficiency and experience. Maintenance and electromechanical personnel are also freed from frequent emergency repair tasks, significantly reducing their workload and enabling them to allocate their time and energy more effectively to routine equipment maintenance and upgrades. From a production efficiency perspective, machines no longer experience frequent downtime due to wire winding issues, leading to a substantial increase in uptime and improved production efficiency. Stable equipment operation ensures the continuity of the production process, effectively guaranteeing both product output and quality. Regarding maintenance costs, the significant reduction in equipment wear and tear caused by wire winding lowers the frequency and difficulty of repairs, leading to a decrease in the use of various maintenance consumables and greatly reducing the company's production and operating costs.

[0036] Example 3: A method for preventing tangling in a TMT-V type texturing machine used for producing blended yarns, characterized in that: the method includes: S1. Fabrication of the wire baffle: The wire baffle is fabricated from stainless steel sheet 2; S2. Material preparation: Prepare an electronic vernier caliper with an accuracy of 0.1mm, a 6.5mm twist drill bit, a matching bench drill or hand drill, 6mm hex socket screws, nuts, an adjustable wrench, a rubber hammer, a marker pen, and a clean cloth. Ensure that the tools are intact and the accuracy meets the installation requirements. S3. Inspect the processed wire baffle: ensure that its dimensions are accurate, its surface is smooth, its bending angle is precise, and the position and diameter of the screw holes meet the design requirements. S4. Install the wire baffle: Clean the surface of the guard plate on the roller of the machine with a clean cloth. Check the guard plate for deformation or damage. If there are any problems, repair or replace it in advance. Ensure that the installation base is firm and reliable. Drill holes in the corresponding position of the guard plate. Then use a 6mm pin or screw to install the wire baffle onto the guard plate through the pull groove 3. Install the cylinder 5 onto the TMT-V type texturing frame. Ensure that the wire baffle can be smoothly pushed out and pushed forward along the pull groove 3 after installation by the cylinder control. S5. Use wire baffle: When producing regular products, push the wire baffle in and tighten it again with screws to ensure that it does not affect the processing of regular products; when processing mixed fiber yarns, pull out the wire baffle and tighten it with the matching screws.

[0037] Cylinders 5 are installed at both ends of the wire-blocking plate. The ends of the cylinders 5 are fixed to the frame of the TMT-V type texturing machine. The difference from embodiment 2 is that when installing the wire-blocking plate in step S4, a 6mm screw or pin is used to fix the wire-blocking plate to the guard plate through the pull-out groove 3, ensuring that the wire-blocking plate can be smoothly pulled out and pushed in along the pull-out groove 3 after installation. Then, one end of the cylinder 5 is installed on the frame of the TMT-V type texturing machine, ensuring that the wire-blocking plate can slide smoothly when the piston rod of the cylinder 5 is extended and retracted. At the same time, it is ensured that the wire-blocking plate is in the retracted state when the cylinder retracts, and the wire-blocking plate is in the pushed-out position when the piston rod of the cylinder 5 extends. When producing regular products, multiple wire-blocking plates can be synchronously retracted at one time by controlling the cylinder 5, so as not to affect the processing of regular products. When processing mixed fiber yarn, all wire-blocking plates are pushed out uniformly by the cylinder 5. Since the TMT-V type texturing machine has 24 sections, each section needs to be equipped with a wire baffle. The synchronous extension and retraction control of the 24 wire baffles can be achieved through 48 cylinders. Compared with screw fixing, it is more efficient, less labor-intensive, and effectively improves work efficiency and product changeover efficiency.

[0038] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
