Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass fiber yarn guiding technology, and in particular to a glass fiber yarn guiding device. Background Technology
[0002] Fiberglass yarn guiding devices are widely used in the textile industry, especially in the production of high-strength fibers and composite materials. Traditional yarn guiding devices suffer from problems such as yarn wear, jamming, or instability, resulting in low production efficiency. To solve these problems, fiberglass yarn guiding devices have been optimized in design to improve the smooth guidance and wear resistance of yarn, thereby enhancing the stability and efficiency of the production process.
[0003] However, in actual use, the following shortcomings still exist. For example, existing fiberglass yarn guiding devices cannot effectively reduce yarn friction, maintain uniform winding, or improve winding efficiency and quality. During the yarn guiding process, significant friction occurs between the yarn and the device components, which can damage the surface fibers of the yarn, reduce its strength, and easily lead to yarn breakage. This increases the difficulty and waste of subsequent processing. The inability to effectively control the tension and direction of the yarn results in inconsistent tension and diameter of the wound fiberglass yarn, affecting the consistency and aesthetics of the product and hindering subsequent processing and use. Due to the increased likelihood of yarn breakage and tangling, frequent machine shutdowns are required for handling, which prevents the equipment from operating at higher speeds, reduces production efficiency, and increases production costs.
[0004] Therefore, this utility model proposes a glass fiber yarn guiding device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a glass fiber yarn guiding device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a glass fiber yarn guiding device, comprising:
[0007] Base plate;
[0008] A winding assembly is placed on top of a base plate. The winding assembly includes a first support block fixed to one side of the top of the base plate, a guide roller is provided on the first support block, and a second support block is fixed to the top of the base plate away from the first support block, and a winding roller is provided on the second support block.
[0009] A guiding assembly is positioned on the top of the base plate near the first support block. The guiding assembly includes a support plate fixed to the top of the base plate, a support seat on the support plate, a second drive motor on the support seat, a gear fixed to the output end of the second drive motor, a limit rod fixed to the gear, a second limit groove on the support plate near the limit rod, the limit rod being disposed within the second limit groove, a fixing block fixed to the support plate, a toothed groove on the fixing block, the gear meshing with the toothed groove, and a yarn guide wheel rotatably connected to the support seat.
[0010] Furthermore, a first drive motor is installed on the second support block, a first drive wheel is fixed to the output end of the first drive motor, a belt is provided on the first drive wheel, a second drive wheel is provided on the belt, and the second drive wheel is fixed on the take-up roller.
[0011] The beneficial effect of adopting the above-mentioned further solution is that, at the second support block, after the first drive motor starts, its output end drives the first drive wheel to rotate. The first drive wheel is connected to the second drive wheel through a belt, thereby transmitting power to the second drive wheel fixed on the take-up roller, driving the take-up roller to rotate, and realizing the take-up action of glass fiber yarn.
[0012] Furthermore, a roller is rotatably connected to the support base, and the roller is mounted on the support plate.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the rollers rotatably connected on the support base roll on the support plate. When the support base needs to move due to the operation of related components, the rollers can reduce the friction between the support base and the support plate, making the movement of the support base smoother and ensuring that the guide roller can accurately guide the yarn.
[0014] Furthermore, a first limiting groove is provided on the support base, and a first limiting block is fixed on the second drive motor, with the first limiting block slidably connected in the first limiting groove.
[0015] The beneficial effect of adopting the above-mentioned further solution is that the first limiting block on the second drive motor slides in the first limiting groove of the support seat. This structure restricts the movement trajectory of the second drive motor. When the second drive motor runs and drives the gear to rotate, it ensures that the meshing between the gear and the tooth groove is stable, making the action of the guide wheel swinging to guide the yarn more reliable.
[0016] Furthermore, a tensioning assembly is provided on the top of the base plate near the second support block. The tensioning assembly includes a support rod fixed to the top of the base plate, and a movable block is slidably connected to the support rod.
[0017] The beneficial effect of adopting the above-mentioned further solution is that in the tensioning assembly on the side of the base plate near the second support block, the moving block can slide on the support rod. When the glass fiber yarn passes through the guide roller, if the yarn tension changes, the moving block will move up and down under the action of the yarn tension and the elastic force of the telescopic spring, automatically adjusting the yarn tension.
[0018] Furthermore, a telescopic spring is provided on the support rod, with one end of the telescopic spring fixed to the base plate and the other end of the telescopic spring fixed to the moving block.
[0019] The beneficial effect of adopting the above-mentioned further solution is that in the tensioning assembly, one end of the telescopic spring is fixed to the base plate and the other end is connected to the moving block. Through the elastic deformation of the telescopic spring, a suitable tension is continuously provided to the yarn to ensure the winding quality.
[0020] Furthermore, a second limiting block is fixed to the top of the support rod, and a guide roller is rotatably connected to the moving block.
[0021] The beneficial effects of adopting the above-mentioned further solution are: the second limiting block at the top of the support rod plays a limiting role. When the moving block moves on the support rod due to changes in yarn tension, the second limiting block can prevent the moving block from detaching from the support rod, ensuring that the tensioning assembly can operate stably and ensuring that the tension adjustment function of the guide roller on the yarn is functioning normally.
[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0023] In this invention, during operation, the yarn is guided by the guide roller of the take-up assembly to the guide wheel of the guide assembly. The second transmission motor drives the gear to rotate, and the gear meshes with the tooth groove on the fixed block, driving the limiting rod to move within the second limiting groove. This enables the guide wheel on the support to reciprocate, ensuring uniform yarn winding. Subsequently, the take-up roller is driven by the drive device to rotate, winding the yarn evenly. Through the adjustment function of the guide assembly and the synergistic effect of the take-up assembly, the device can effectively reduce yarn friction, maintain uniform winding, and improve winding efficiency and quality.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] like Figures 1-4 As shown, this embodiment provides a technical solution: a glass fiber yarn guiding device, comprising:
[0036] Base plate 1;
[0037] The winding assembly 2 is placed on the top of the base plate 1. The winding assembly 2 includes a first support block 21 fixed on one side of the top of the base plate 1, a guide roller 22 is provided on the first support block 21, and a second support block 23 is fixed on the top of the base plate 1 away from the first support block 21, and a winding roller 28 is provided on the second support block 23.
[0038] The guide assembly 3 is located on the top of the base plate 1 near the first support block 21. The guide assembly 3 includes a support plate 31 fixed to the top of the base plate 1, a support base 32 on the support plate 31, a second drive motor 34 on the support base 32, a gear 37 fixed to the output end of the second drive motor 34, a limit rod 38 fixed to the gear 37, and a second limit groove 39 opened on the support plate 31 near the limit rod 38, with the limit rod 38 disposed in the second limit groove 39. A fixing block 310 is fixed on the support plate 31, and a toothed groove 311 is formed on the fixing block 310. A gear 37 meshes with the toothed groove 311. A guide roller 312 is rotatably connected to the support base 32. When the glass fiber guiding device is in operation, the glass fiber yarn first arrives at the winding assembly 2. In the winding assembly 2, the guide roller 22 is installed on the first support block 21 to smoothly guide the yarn to the guide roller 312 of the guiding assembly 3. The guiding assembly 3 is driven by a second transmission motor 34. After it starts, it outputs... The shaft drives the gear 37 to rotate at high speed. The gear 37 precisely meshes with the tooth groove 311 on the fixed block 310. At the same time, the limiting rod 38 fixed on the gear 37 moves orderly within the second limiting groove 39. This series of linkages causes the guide wheel 312 on the support base 32 to reciprocate. The reciprocating motion of the guide wheel 312 can evenly distribute the yarn in the subsequent winding area, laying the foundation for the even winding of the winding roller 28. After the guide wheel 312 completes the even guidance of the yarn, the winding roller 28 starts to operate. The winding roller 28 is driven by the drive device, namely the first transmission motor 24. The first transmission wheel 25 at the output end of the first transmission motor 24 drives the second transmission wheel 27 through the belt 26, thereby causing the winding roller 28 to rotate and evenly wind the yarn. The guiding component 3 can flexibly adjust the yarn position to reduce the friction between the yarn and the device components. The winding component 2 winds the yarn stably. The two work together to effectively improve the winding efficiency and ensure the winding quality, making the winding process of glass fiber yarn more stable and efficient.
[0039] The above solutions also have the problem of not being able to maintain the yarn at a suitable tension when the glass fiber yarn is being guided, such as... Figures 1-2 As shown: A first drive motor 24 is installed on the second support block 23. A first drive wheel 25 is fixed to the output end of the first drive motor 24. A belt 26 is provided on the first drive wheel 25. A second drive wheel 27 is provided on the belt 26. The second drive wheel 27 is fixed on the take-up roller 28. At the second support block 23, when the first drive motor 24 is turned on, its output end rotates, driving the first drive wheel 25 connected to it to rotate. The first drive wheel 25 efficiently transmits power to the second drive wheel 27 through the belt 26. The second drive wheel 27 is fixed on the take-up roller 28, thereby driving the take-up roller 28 to rotate, completing the take-up action of the glass fiber yarn, realizing an important link in the production process.
[0040] like Figure 1 as well as Figures 3-4 As shown, a roller 33 is rotatably connected to the support base 32. The roller 33 is set on the support plate 31. The roller 33 on the support base 32 is in close cooperation with the support plate 31. When the operation of the relevant components causes the support base 32 to move, the roller 33 starts to roll. It effectively reduces the friction between the support base 32 and the support plate 31, making the movement of the support base 32 smooth and stable. This ensures that the guide wheel 312 can accurately guide the yarn and ensure the correct yarn direction. The support base 32 is provided with a first limiting groove 35. The second drive motor 34 is fixed with a first limiting block 36. The first limiting block 36 is slidably connected in the first limiting groove 35. The first limiting block 36 of the second drive motor 34 moves in the first limiting groove 35 of the support base 32. This structure strictly limits the movement trajectory of the motor. When the motor runs and drives the gear 37 to rotate, due to the limiting effect, the meshing of the gear 37 and the tooth groove 311 is always stable, so that the action of the guide wheel 312 swinging to guide the yarn is stable and reliable, ensuring the uniform distribution of the yarn.
[0041] like Figure 1 as well as Figure 5 As shown, a tensioning assembly 4 is provided on the top of the base plate 1 near the second support block 23. The tensioning assembly 4 includes a support rod 41 fixed to the top of the base plate 1, and a movable block 42 slidably connected to the support rod 41. In the tensioning assembly 4 near the second support block 23 of the base plate 1, the movable block 42 can slide flexibly along the support rod 41. When the glass fiber yarn passes through the guide roller 45, if the tension changes, the movable block 42 will automatically move up and down under the combined action of the yarn tension and the elastic force of the telescopic spring 43, so as to adjust the yarn tension in time and maintain the yarn in a suitable tension state. A telescopic spring 43 is provided on the support rod 41. One end of the telescopic spring 43 is fixed to the base plate 1, and the other end of the telescopic spring 43 is fixed to the movable block 42. On the moving block 42, inside the tensioning assembly 4, one end of the telescopic spring 43 is firmly fixed to the base plate 1, and the other end is connected to the moving block 42. Through the elastic deformation of the telescopic spring 43, it continuously provides just the right tension to the yarn, effectively ensuring the winding quality. The top of the support rod 41 is fixed with a second limiting block 44, and the moving block 42 is rotatably connected with a guide roller 45. The second limiting block 44 at the top of the support rod 41 is crucial. When the moving block 42 moves on the support rod 41 due to changes in yarn tension, the second limiting block 44 can effectively prevent the moving block 42 from detaching from the support rod 41, ensuring the stable operation of the tensioning assembly 4, allowing the guide roller 45 to perform its yarn tension adjustment function normally, and ensuring the stability of the entire yarn guiding process.
[0042] Working principle:
[0043] like Figures 1-5As shown, when the fiberglass yarn guiding device is in operation, the base plate 1 provides stable support for the entire device. The fiberglass yarn first enters the winding assembly 2 from the starting end. In the winding assembly 2, the guide roller 22, which is fixed on the first support block 21 on one side of the top of the base plate 1, plays a preliminary guiding role, smoothly guiding the yarn to the guide wheel 312 of the guiding assembly 3. The guiding assembly 3 is driven by the second transmission motor 34. After the motor starts, the output shaft drives the gear 37 to rotate at high speed. The gear 37 interacts with the teeth on the fixed block 310. The groove 311 engages precisely, and simultaneously, the limiting rod 38 fixed on the gear 37 moves orderly within the second limiting groove 39. This series of linkages causes the guide wheel 312 on the support 32 to reciprocate. This reciprocating motion evenly distributes the yarn in the subsequent winding area, laying the foundation for the even winding of the take-up roller 28. The roller 33 rotatably connected to the support 32 reduces the friction between the support 32 and the support plate 31 when the support 32 needs to move due to the operation of related components, ensuring that the guide wheel 312 accurately guides the yarn. The first limiting block 36 on the second drive motor 34 slides within the first limiting groove 35, ensuring the stable movement of the second drive motor 34 within the support base 32. This allows the guide wheel 312 to reliably guide the yarn. After the guide wheel 312 completes the uniform guidance of the yarn, the take-up roller 28 begins to work. The first drive motor 24 on the second support block 23 starts, and its output end drives the first drive wheel 25 to rotate. The power is transmitted to the second drive wheel 27 via the belt 26, driving the take-up roller 28 to rotate and realize the yarn take-up. On the tensioning component 4 near the second support block 23 on the base plate 1, the moving block 42 can slide on the support rod 41. Through the elastic deformation of the telescopic spring 43, the yarn tension is automatically adjusted according to the change in yarn tension to ensure that the yarn is always in a suitable tension state. The second limiting block 44 at the top of the support rod 41 prevents the moving block 42 from disengaging, ensuring the stable operation of the tensioning component 4. The guide component 3 and the take-up component 2 work together to effectively improve the take-up efficiency and quality, making the yarn take-up process stable and efficient.
[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
