Description

Technical Field

[0001] The invention belongs to the technical field of yarn drawing for glass fiber reinforced plastic grating production, and in particular relates to a yarn drawing mechanism for glass fiber reinforced plastic grating production. Background Art

[0002] The yarn pulling mechanism for FRP grating production is a key device in its manufacturing process. It is mainly responsible for evenly stretching and unfolding the glass fiber yarn, ensuring that the yarn is laid on the mold in a predetermined direction and tension, so that the FRP grating can have good strength and structural stability, and improve product quality and performance.

[0003] In the existing yarn drawing mechanism for FRP grating production, when multiple yarns are running at the same time during the yarn drawing process, if there is no separator to separate them, the yarns are very likely to get tangled with each other. Once the yarns are tangled together, the original yarn drawing rhythm and path will be disrupted, resulting in uneven yarn stretching, some yarns may be overstretched, and some may be understretched. This will not only affect the production efficiency of FRP grating, but also greatly reduce the quality of the product, such as causing uneven local strength of the grating, affecting its overall performance and service life. Summary of the invention

[0004] The purpose of the present invention is to provide a yarn drawing mechanism for producing glass fiber reinforced plastic gratings in order to solve the above-mentioned problem of production efficiency.

[0005] The technical solution adopted by the present invention is as follows: a yarn drawing mechanism for the production of fiberglass gratings, comprising a yarn drawing machine base, the upper surface of the yarn drawing machine base is fixedly connected with a bottom plate, the bottom plate is fixedly connected with a plurality of support columns at one end relative to the yarn drawing machine base, the support column is fixedly connected with a top plate at one end relative to the bottom plate, a yarn separating slide bar is provided in a groove opened on the upper surface of the bottom plate, a plurality of sliding blocks are slidably connected to the outer surface of the yarn separating slide bar, a yarn separating rod is fixedly connected to the upper surface of the sliding block, and a handle is fixedly connected to one side of the sliding block.

[0006] By adopting the above technical scheme, a slidably adjustable yarn separation rod structure is added to a yarn drawing mechanism for glass fiber reinforced plastic grating production. The operator can hold the handle to slide the sliding block along the yarn separation sliding rod, and the yarn separation rod can be driven to slide together through the sliding rods at the upper and lower ends. During the yarn drawing process, multiple strands of yarn are stretched at the same time. The slidably adjustable yarn separation rod can separate different strands of yarn to prevent them from interweaving and entangled with each other. Yarn entanglement may cause uneven yarn drawing, affecting the quality and strength uniformity of the glass fiber reinforced plastic grating, and the separation rod effectively solves this problem, ensuring that each strand of yarn can be stretched according to the predetermined path and tension. By sliding and adjusting the position of the separation rod, the spacing between different yarns can be accurately controlled. Stable yarn spacing helps to make the glass fiber more evenly distributed in the matrix material during the glass fiber reinforced plastic grating molding process, thereby making the product structure more regular and the performance more reliable. Yarns of different thicknesses and materials may be used in the production of glass fiber reinforced plastic grating. The slidably adjustable separation rod structure can be flexibly adjusted according to the actual specifications of the yarn. For example, for thicker yarns, the spacing between the dividing rods can be appropriately widened; for thinner yarns, the spacing can be narrowed to meet the separation requirements of different yarns during the yarn drawing process, without the need to frequently replace the dividing device for yarns of different specifications.

[0007] In a preferred embodiment, a support platform is fixedly connected to the upper surface of the yarn drawing machine base, a plurality of cylinders are fixedly connected to the upper surface of the support platform, a limiting rod is fixedly connected to one side of the support platform relative to the yarn drawing machine base, and a limiting block is fixedly connected to one side of the support platform.

[0008] By adopting the above technical scheme, a retractable threading structure is added to a yarn pulling mechanism for glass fiber reinforced plastic grating production. The cylinder can drive the guide frame to move in the vertical direction, and the limit rod can ensure the stability of the guide frame movement. In actual production, the length of the yarn varies, and the height of the starting point of the threading may also be different. The retractable threading structure that can move in the vertical direction can flexibly adjust its own length according to the specific length of the yarn, and can move to a suitable height position in the vertical direction, so as to facilitate the accurate introduction of the yarn into the starting end of the threading structure, greatly reducing the difficulty of the initial threading, and can complete the threading operation more efficiently regardless of the length of the yarn or the height of the starting point. The yarn guide path of the yarn pulling mechanism is often more complicated, and there may be ups and downs, twists and turns, etc. This retractable and vertically movable threading structure can adjust its own position and length in time according to the changes in the yarn guide path in the vertical direction, ensure that the yarn can pass through each yarn guide component smoothly, effectively avoid the problems of dragging, entanglement, and jamming of the yarn during the threading process, and improve the fluency and success rate of threading. Yarn tension has a significant impact on the production quality of FRP gratings. The threading structure can not only fine-tune the tension by stretching and retracting, but also make further fine adjustments by moving in the vertical direction. For example, when the yarn tension needs to be increased, in addition to extending the threading structure, it can also be appropriately moved up in the vertical direction to change the combined effects of friction, gravity, etc. on the yarn when it passes through, thereby more accurately achieving the purpose of increasing the tension; conversely, if the tension needs to be reduced, the threading structure can be retracted and moved down. This multi-dimensional adjustment method can achieve more precise control of yarn tension and ensure the consistency and stability of product quality.

[0009] In a preferred embodiment, a guide frame is fixedly connected to the upper surface of the cylinder, and a front plate is fixedly connected to one side of the guide frame.

[0010] By adopting the above technical solution, the front plate in the yarn drawing mechanism for FRP grating production mainly plays the role of limiting excessive forward deviation of the yarn. It sets the front boundary for the stretching of the yarn, ensures that the yarn can move in an orderly manner in the predetermined direction, prevents it from deviating from the normal path due to external forces and other factors during the yarn drawing process, ensures the stable development of the yarn drawing operation, and at the same time provides certain protection for internal components to avoid external interference. The key use of the guide frame is to provide precise guidance for the yarn's travel route. After the yarn is released from the discharge disc head, it can accurately enter subsequent operations such as stretching and weaving by relying on the specific channel framework constructed by the guide frame, effectively avoiding problems such as yarn deviation and entanglement, and ensuring a smooth yarn drawing process and regular yarn arrangement.

[0011] In a preferred embodiment, the guide frame is fixedly connected to a rear plate on one side relative to the front plate, a plurality of guide posts are fixedly connected to one side of the front plate, and a guide hole is fixedly connected to one side of the guide post.

[0012] By adopting the above technical solution, the rear plate corresponds to the front plate, and its important function is to prevent the yarn from excessively deviating backwards during stretching. It defines a stable boundary for the yarn at the rear end, maintains the stability of the yarn within a reasonable stretching range, ensures that the yarn will not move backwards out of the normal range due to tension and other reasons during the yarn drawing process, and protects the rear parts to prevent improper contact of the yarn from causing equipment or yarn failure. The guide column is an important support for the yarn to maintain a straight line in the yarn drawing mechanism. The yarn slides along the guide column, and with its straight and fixed shape, it clarifies the direction of travel for the yarn, ensuring that the yarn can accurately reach each predetermined position during operations such as stretching, which is crucial to ensuring the accuracy of yarn drawing and the quality of the final FRP grating product. The guide hole provides a precise positioning channel for the yarn to pass through the yarn drawing mechanism. The yarn needs to pass through each guide hole in turn, so that it is strictly limited to a specific path, thereby effectively preventing the yarn from deviating from the preset route, ensuring the standardization and orderliness of the yarn stretching operation, and is a key link in achieving accurate yarn drawing, which directly affects product quality.

[0013] In a preferred embodiment, a plurality of sliders are fixedly connected to the lower end of the rear plate, and a threading hole is fixedly connected to one side of the slider.

[0014] By adopting the above technical solution, the slider in the yarn drawing mechanism mainly cooperates with other components to assist the movement of the yarn. For example, in coordination with the guide column, guide frame, etc., when the yarn is stretched, the slider can slide on the corresponding track with the movement of the yarn, which can not only reduce the friction between the yarn and the fixed parts, but also ensure the continuity of the yarn movement, which helps to improve the efficiency and quality of yarn drawing. The threading hole is the only way for the yarn to enter a specific area of ​​the yarn drawing mechanism or connect different components. After the yarn is released from the discharge disc head, it must pass through the threading hole to accurately enter the area corresponding to the subsequent operation link. It accurately plans the yarn's route to ensure that the yarn can flow in an orderly manner in the yarn drawing mechanism, which is of great significance to the smooth progress of the entire yarn drawing process.

[0015] In a preferred embodiment, a groove opened on one side of the yarn drawing machine base is fixedly connected to a tool placement box slide rod, the outer surface of the tool placement box slide rod is slidably connected to a tool placement box slider, a positioning plug is provided on one side of the tool placement box slider, a connecting rod is fixedly connected to one side of the connecting rod, a yarn clamping tool placement box is fixedly connected to one side of the connecting rod, and a plurality of partitions are fixedly connected to the upper surface of the yarn clamping tool placement box.

[0016] By adopting the above technical scheme, a slidable yarn clamping tool placement box structure is added to a yarn drawing mechanism for glass fiber reinforced plastic grating production. The yarn clamping tool placement box can be driven by the tool placement box slider to slide along the outer surface of the tool placement box slide bar, and the positioning plug can fix the tool placement box structure on the positioning hole on one side of the yarn drawing machine base. During the yarn drawing process, operators often need to use various yarn clamping tools, such as tweezers, pliers, etc., to deal with yarn breakage, adjust the yarn position, etc. The slidable placement box structure allows operators to easily slide the placement box to the most convenient place to take the tool according to their working position, without having to walk around the equipment to find the tool, which greatly improves work efficiency and saves operation time. The yarn drawing operation may involve different operation links and scenes. For example, in the yarn introduction stage, stretching stage, finishing stage, etc., the operator's position and operation posture may be different. The slidable tool box can flexibly adapt to these changes. No matter where the operator is performing any operation, the tool box can be quickly slid to a convenient position, making it easy to take the required tools at any time.

[0017] In a preferred embodiment, a plurality of support plates are fixedly connected to the upper surface of the yarn drawing machine base.

[0018] By adopting the above technical solution, the core function of the support plate is to provide stable support for other components in the yarn drawing mechanism. It bears the weight of the unwinding motor, rotating roller and other components, ensuring that these components can maintain a stable position during operation and will not sink or deviate due to their own weight or operating vibration, thus laying a solid foundation for the continuous and stable development of the yarn drawing operation.

[0019] In a preferred embodiment, a discharge motor is provided at the upper end of the support plate.

[0020] By adopting the above technical solution, the unwinding motor is the key power source for controlling the yarn unwinding speed in the yarn drawing mechanism. By driving the rotating roller to rotate, the unwinding disc head is driven to rotate, so that the yarn can be unwound in an orderly manner from the unwinding disc head. The unwinding speed can be accurately adjusted according to the production process requirements to ensure that the yarn supply amount matches the drawing speed, etc., which plays a decisive role in ensuring product quality and production efficiency.

[0021] In a preferred embodiment, a rotating roller is disposed on one side of the unloading motor, and a side column is disposed on one end of the rotating roller opposite to the unloading motor.

[0022] By adopting the above technical solution, the rotating roller is an important component in the yarn drawing mechanism to receive the power of the feeding motor and realize the yarn transmission. The feeding motor drives it to rotate, and the rotating roller drives the feeding disc to rotate together, so that the yarn can be continuously discharged from the feeding disc. At the same time, during the yarn discharge process, the rotating roller can also play a certain traction role on the yarn, ensuring the smooth discharge link and laying the foundation for the subsequent yarn drawing operation. The side column connects the rotating roller and the feeding disc, which ensures the integrity and unity of the overall structure and is one of the important structures in the overall structure.

[0023] In a preferred embodiment, a material discharge disc head is provided at one end of the side column relative to the rotating roller.

[0024] By adopting the above technical solution, the unwinding disc is crucial as the source component for storing and initially releasing the yarn. The yarn is stored on it in a wound form. Driven by the unwinding motor and the rotating roller, the unwinding disc rotates to release the yarn circle by circle, providing a continuous supply of yarn for subsequent stretching, weaving and other operations of the yarn drawing mechanism. It is the starting point of the entire yarn drawing process and plays a fundamental role in the development of yarn drawing operations.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. In the present invention, a yarn separation rod structure with sliding adjustment is added to a yarn drawing mechanism for glass fiber reinforced plastic grating production. The operator can hold the handle to slide the sliding block along the yarn separation sliding rod, and the yarn separation rod can be driven to slide together through the sliding rods at the upper and lower ends. During the yarn drawing process, multiple strands of yarn are stretched at the same time. The slidable and adjustable yarn separation rod can separate different strands of yarn to prevent them from interweaving and entangled with each other. Yarn entanglement may cause uneven yarn drawing, affecting the quality and strength uniformity of the glass fiber reinforced plastic grating, and the separation rod effectively solves this problem, ensuring that each strand of yarn can be stretched according to a predetermined path and tension. By sliding and adjusting the position of the separation rod, the spacing between different yarns can be accurately controlled.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] Reference Figure 1-6 ,

[0038] Reference Figure 1-2The upper surface of the yarn drawing machine base 1 is fixedly connected with a bottom plate 2, and one end of the bottom plate 2 relative to the yarn drawing machine base 1 is fixedly connected with a plurality of support columns 3, and one end of the support column 3 relative to the bottom plate 2 is fixedly connected with a top plate 4, and the groove on the upper surface of the bottom plate 2 is provided with a yarn separation slide bar 5, and the outer surface of the yarn separation slide bar 5 is slidably connected with a plurality of sliding blocks 6, and the upper surface of the sliding block 6 is fixedly connected with a yarn separation rod 7, and one side of the sliding block 6 is fixedly connected with a handle 8. A yarn separation rod structure that can be slidably adjusted is added to a yarn drawing mechanism for glass fiber reinforced plastic grating production. The operator can hold the handle 8 to slide the sliding block 6 along the yarn separation slide bar 5, and the yarn separation rod 7 can be driven to slide together through the sliding bars at the upper and lower ends. During the yarn drawing process, multiple strands of yarn are stretched at the same time. The slidably adjustable yarn separation rod can separate different strands of yarn to prevent them from being intertwined and entangled with each other. Yarn entanglement may cause uneven yarn pulling, affecting the quality and strength uniformity of FRP grating, while the separator rod effectively solves this problem, ensuring that each strand of yarn can be stretched according to the predetermined path and tension. By sliding and adjusting the position of the separator rod, the spacing between different yarns can be accurately controlled. Stable yarn spacing helps to make the glass fiber more evenly distributed in the matrix material during the FRP grating molding process, thereby making the product structure more regular and the performance more reliable. Yarns of different thicknesses and materials may be used in the production of FRP grating. The slidable and adjustable separator rod structure can be flexibly adjusted according to the actual specifications of the yarn. For example, for thicker yarns, the spacing between the separator rods can be appropriately widened; for thinner yarns, the spacing can be narrowed to meet the separation requirements of different yarns during the yarn pulling process, without the need to frequently replace the separator for yarns of different specifications.

[0039] Reference Figure 1 , Figure 3, a support platform 9 is fixedly connected to the upper surface of the yarn drawing machine base 1, and a plurality of cylinders 10 are fixedly connected to the upper surface of the support platform 9. A limit rod 11 is fixedly connected to one side of the support platform 9 relative to the yarn drawing machine base 1, and a limit block 12 is fixedly connected to the limit rod 11 relative to one side of the support platform 9. A retractable threading structure is added to a yarn drawing mechanism for glass fiber reinforced plastic grating production. The cylinder 10 can drive the guide frame 14 to move in the vertical direction, and the limit rod 11 can ensure the stability of the movement of the guide frame 14. In actual production, the length of the yarn varies, and the height of the starting point of the threading may also be different. The retractable threading structure that can move in the vertical direction can flexibly adjust its own length according to the specific length of the yarn, and can move to a suitable height position in the vertical direction, so as to facilitate the accurate introduction of the yarn into the starting end of the threading structure, greatly reducing the difficulty of the initial threading, and can complete the threading operation more efficiently regardless of the length of the yarn or the height of the starting point. The yarn guide path of the yarn drawing mechanism is often more complicated, and there may be ups and downs, twists and turns, etc. This retractable and vertically movable threading structure can adjust its position and length in time according to the changes in the yarn guide path in the vertical direction, ensuring that the yarn can pass through each yarn guide component smoothly, effectively avoiding problems such as dragging, entanglement, and jamming of the yarn during the threading process, and improving the smoothness and success rate of threading. Yarn tension has a significant impact on the production quality of FRP gratings. The threading structure can not only fine-tune the tension by telescoping, but also further fine-tune it by moving in the vertical direction. For example, when it is necessary to increase the yarn tension, in addition to extending the threading structure, it can also be appropriately moved up in the vertical direction to change the combined effects of friction, gravity, etc. on the yarn when passing through, so as to more accurately achieve the purpose of increasing the tension; conversely, if you want to reduce the tension, you can shrink and move the threading structure downward. This multi-dimensional adjustment method can achieve more precise control of yarn tension and ensure the consistency and stability of product quality.

[0040] Reference Figure 3-4 , a guide frame 14 is fixedly connected to the upper surface of the cylinder 10, and a front plate 13 is fixedly connected to one side of the guide frame 14. The front plate 13 mainly plays the role of limiting the excessive forward deviation of the yarn in the yarn drawing mechanism for FRP grating production. It sets the front boundary for the stretching of the yarn, ensures that the yarn can move in an orderly manner in a predetermined direction, prevents it from deviating from the normal path due to external forces and other factors during the yarn drawing process, ensures the stable development of the yarn drawing operation, and at the same time provides certain protection for the internal components to avoid external interference.

The rear plate 15 corresponds to the front plate, and its important function is to prevent the yarn from excessively deviating backwards during stretching. It defines a stable boundary for the yarn at the rear end, maintains the stability of the yarn within a reasonable stretching range, ensures that the yarn will not deviate backwards from the normal range due to tension and other reasons during the yarn drawing process, and protects the rear parts to prevent improper contact of the yarn from causing equipment or yarn failure. The guide post 16 is an important support for the yarn to maintain a straight line in the yarn drawing mechanism. The yarn slides along the guide post 16, and with its straight and fixed shape, it clarifies the direction of travel for the yarn, ensuring that the yarn can accurately reach each predetermined position during operations such as stretching, which is crucial to ensuring the accuracy of yarn drawing and the quality of the final glass fiber reinforced plastic grating product. The guide hole 17 provides a precise positioning channel for the yarn to pass through the yarn drawing mechanism. The yarn needs to pass through each guide hole 17 in sequence, thereby being strictly confined to a specific path, thereby effectively preventing the yarn from deviating from the preset route, ensuring the standardization and orderliness of the yarn stretching operation, which is a key link in achieving accurate yarn drawing and directly affects product quality.

[0042] Reference Figure 4 , a plurality of sliders 18 are fixedly connected to the lower end of the rear plate 15, and a threading hole 19 is fixedly connected to one side of the slider 18. The slider 18 is mainly used to cooperate with other components to assist the movement of the yarn in the yarn drawing mechanism. For example, in cooperation with the guide column, guide frame, etc., when the yarn is stretched, the slider 18 can slide on the corresponding track with the movement of the yarn, which can not only reduce the friction between the yarn and the fixed components, but also ensure the continuity of the yarn movement, which helps to improve the efficiency and quality of yarn drawing. The threading hole 19 is the only way for the yarn to enter a specific area of ​​the yarn drawing mechanism or connect different components. After the yarn is released from the discharge disc head, it must pass through the threading hole to accurately enter the area corresponding to the subsequent operation link. It accurately plans the yarn's route to ensure that the yarn can flow in an orderly manner in the yarn drawing mechanism, which is of great significance to the smooth progress of the entire yarn drawing process.

A yarn drawing mechanism for glass fiber reinforced plastic grating production is provided with a slidable yarn clamping tool placement box structure. The yarn clamping tool placement box 24 can be driven by the tool placement box slider 21 to slide along the outer surface of the tool placement box slider 20, and the positioning plug 22 can fix the tool placement box structure on the positioning hole on one side of the yarn drawing machine base 1. In the yarn drawing process, operators often need to use various yarn clamping tools, such as tweezers, pliers, etc., to deal with yarn breakage, adjust the yarn position, etc. The slidable placement box structure allows operators to easily slide the placement box to the most convenient place to access tools according to their working position, without having to walk around the equipment to find tools, which greatly improves work efficiency and saves operation time. Yarn drawing operations may involve different operation links and scenarios. For example, in the yarn introduction stage, stretching stage, finishing stage, etc., the position and operation posture of the operator may be different. The slidable placement box can flexibly adapt to these changes. No matter where the operator is performing any operation, the tool placement box can be quickly slid to a convenient position, so that the required tools can be easily accessed at any time.

[0044] Reference Figure 1 , Figure 6 The upper surface of the yarn drawing machine base 1 is fixedly connected with a plurality of support plates 26. The core function of the support plates 26 is to provide stable support for other components in the yarn drawing mechanism. It bears the weight of the unwinding motor, rotating roller and other components, ensuring that these components can maintain a stable position during operation and will not sink or deviate due to their own weight or operating vibration, thus laying a solid foundation for the continuous and stable development of the yarn drawing operation.

[0045] Reference Figure 6 , a feeding motor 27 is provided at the upper end of the support plate 26. The feeding motor 27 is the key power source for controlling the feeding speed of the yarn in the yarn drawing mechanism. By driving the rotating roller to rotate, the feeding disc head is driven to rotate, so that the yarn is discharged in an orderly manner from the feeding disc head, and the feeding speed can be accurately adjusted according to the production process requirements to ensure that the yarn supply amount matches the drawing speed, etc., which plays a decisive role in ensuring product quality and production efficiency.

[0046] Reference Figure 6A rotating roller 28 is provided on one side of the unloading motor 27, and a side column 29 is provided on one end of the rotating roller 28 relative to the unloading motor 27. The rotating roller 28 is an important component in the yarn drawing mechanism to receive the power of the unloading motor and realize the yarn transmission. The unloading motor drives it to rotate, and the rotating roller drives the unloading disc head to rotate together, so that the yarn can be continuously released from the unloading disc head. At the same time, during the yarn release process, the rotating roller can also play a certain traction role on the yarn, ensuring the smooth progress of the unloading link and laying the foundation for the subsequent yarn drawing operation. The side column 29 connects the rotating roller 28 and the unloading disc head 30, which ensures the integrity and unity of the overall structure and is one of the important structures in the overall structure.

[0047] Reference Figure 6 , a feeding disc 30 is arranged at one end of the side column 29 relative to the rotating roller 28. The feeding disc 30 is very important as a source component for storing and initially releasing the yarn. The yarn is stored on it in a winding form. Driven by the feeding motor and the rotating roller, the feeding disc 30 rotates to release the yarn circle by circle, providing a continuous supply of yarn for subsequent stretching, weaving and other operations of the yarn drawing mechanism. It is the starting point of the entire yarn drawing process and plays a fundamental role in the development of the yarn drawing operation.

[0048] Working principle:

[0049] In the present invention, a slidably adjustable yarn separator rod structure is added to a yarn drawing mechanism for producing FRP grating. During the yarn drawing process, multiple strands of yarn are stretched at the same time. The slidably adjustable yarn separator rod can separate different strands of yarn to prevent them from interweaving and entangled with each other. Yarn entanglement may cause uneven yarn drawing, affecting the quality and strength uniformity of the FRP grating, and the separator rod effectively solves this problem, ensuring that each strand of yarn can be stretched according to a predetermined path and tension. By sliding and adjusting the position of the separator rod, the spacing between different yarns can be accurately controlled. Stable yarn spacing helps to make the glass fiber more evenly distributed in the matrix material during the FRP grating molding process, thereby making the product structure more regular and the performance more reliable. Yarns of different thicknesses and materials may be used in the production of FRP grating. The slidably adjustable separator rod structure can be flexibly adjusted according to the actual specifications of the yarn. For example, for thicker yarns, the spacing between the dividing rods can be appropriately widened; for thinner yarns, the spacing can be narrowed to meet the separation requirements of different yarns during the yarn drawing process, without the need to frequently replace the dividing device for yarns of different specifications.

[0050] In the present invention, a retractable threading structure is added to a yarn drawing mechanism for producing FRP grating. In actual production, the length of the yarn varies, and the height of the starting point of the threading may also vary. The retractable threading structure that can move in the vertical direction can flexibly adjust its own length according to the specific length of the yarn, and can move to a suitable height position in the vertical direction, so as to facilitate the accurate introduction of the yarn into the starting end of the threading structure, greatly reducing the difficulty of the initial threading, and can complete the threading operation more efficiently regardless of the length of the yarn or the height of the starting point. The yarn guide path of the yarn drawing mechanism is often more complicated, and there may be ups and downs, twists and turns, etc. This retractable and vertically movable threading structure can adjust its own position and length in time according to the changes in the yarn guide path in the vertical direction, ensure that the yarn can pass through each yarn guide component smoothly, effectively avoid the problems of dragging, entanglement, and jamming of the yarn during the threading process, and improve the smoothness and success rate of the threading. The yarn tension has a significant impact on the production quality of FRP grating. The threading structure can not only fine-tune the tension by telescoping, but also further fine-tune it by moving in the vertical direction. For example, when the yarn tension needs to be increased, in addition to extending the threading structure, it can also be appropriately moved up in the vertical direction to change the combined effects of friction, gravity, etc. on the yarn when it passes through, thereby more accurately achieving the purpose of increasing the tension; conversely, if the tension needs to be reduced, the threading structure can be contracted and moved down. This multi-dimensional adjustment method can achieve more precise control of the yarn tension and ensure the consistency and stability of product quality.

[0051] In the present invention, a slidable yarn clamping tool placement box structure is added to a yarn drawing mechanism for glass fiber reinforced plastic grating production. During the yarn drawing process, operators often need to use various yarn clamping tools, such as tweezers, pliers, etc., to deal with yarn breakage, adjust the yarn position, etc. The slidable placement box structure allows operators to easily slide the placement box to the most convenient place to access tools according to their working position, without having to walk around the equipment to find tools, which greatly improves work efficiency and saves operation time. Yarn drawing operations may involve different operation links and scenarios. For example, in the yarn introduction stage, stretching stage, finishing stage, etc., the position and operation posture of the operator may be different. The slidable placement box can flexibly adapt to these changes. No matter what operation the operator performs in which position, the tool placement box can be quickly slid to a convenient position, so that the required tools can be easily accessed at any time.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
