Description

Technical Field

[0001] This utility model relates to the field of glass fiber cloth production technology, specifically to a glass fiber yarn tension adjustment device. Background Technology

[0002] When glass fiber yarn is used as warp yarn in the weaving process, its brittleness, low elongation, and high rigidity make tension control particularly critical. If the tension of each warp yarn is inconsistent, it can easily lead to uneven fabric surface, seriously affecting the quality of the finished product. In the current method of weaving glass fiber yarn into glass fiber cloth, the tension of each glass fiber yarn is individually controlled by installing tensioners on the yarn frame. However, the tension of the yarn fluctuates during the conveying process, and there is no linkage between each yarn during the conveying process, resulting in poor overall tension consistency. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a glass fiber yarn tension adjustment device that can adjust the tension of each glass fiber yarn as warp yarn in real time, ensuring good tension consistency.

[0004] This utility model discloses a glass fiber yarn tension adjustment device, including a base, with mounting seats at both ends of the front and rear sides of the base. A first roller is rotatably mounted between the front mounting seats, and a second roller is rotatably mounted between the rear mounting seats. The first and second rollers are at the same height and parallel to each other. An air tank is fixedly mounted on the base between the first and second rollers. An air inlet pipe is provided on the air tank, and a valve is provided on the air inlet pipe. Mounting holes are provided at intervals along the length direction of the first roller at the upper end of the air tank. A cylinder with the same inner diameter is vertically mounted on the mounting holes. A piston is slidably mounted inside the cylinder. A piston rod is provided at the upper end of the piston. An end cap for the piston rod to pass through is provided at the upper end of the cylinder. The upper end of the piston rod passes through the end cap, and a fixed pulley is provided at the upper end of the piston rod.

[0005] The aforementioned device is installed between the fiberglass cloth weaving equipment and the yarn frame, so that each fiberglass yarn sequentially passes under the first roller, above the fixed pulley, and below the second roller before being fed into the fiberglass yarn weaving equipment. High-pressure gas is introduced into the air tank through the air inlet pipe connected to the high-pressure air pipe. After reaching a certain pressure, the valve is closed, pushing the pistons and piston rods in multiple vertically arranged cylinders upward. The fixed pulleys press against the fiberglass yarn. When the tension of the fiberglass yarn fluctuates during the conveying process, i.e., when the tension of the fiberglass yarn increases, the piston rod and the fixed pulley on the piston rod descend, reducing the tension of the fiberglass yarn; when the tension of the fiberglass yarn decreases, the piston rod and the fixed pulley on the piston rod rise, increasing the tension of the fiberglass yarn. Since each cylinder is connected to the air tank, the air pressure inside is consistent. Therefore, the constant tension of the fiberglass yarn can be effectively ensured during the real-time adjustment of the fiberglass yarn tension by the up-and-down movement of the fixed pulleys.

[0006] To control the air pressure inside the gas storage tank in real time, a pressure sensor is installed inside the tank, and the valve is an electromagnetic control valve. The pressure sensor and the electromagnetic control valve are electrically connected to a controller. The air inlet pipe is connected to a high-pressure gas pipe. The pressure sensor monitors the gas pressure in the storage tank in real time, and the controller dynamically adjusts the opening and closing of the electromagnetic valve to ensure that the gas pressure strictly matches the set value.

[0007] To reduce weight and improve response speed, the piston rod is made of hollow plastic tube, and the fixed pulley is made of aluminum alloy.

[0008] The fiberglass yarn tension regulating device obtained by this invention has the following advantages: the air tank forms a unified air pressure system by connecting multiple synchronously operating cylinder piston units. When the tension of a single fiberglass yarn fluctuates, the corresponding fixed pulley will automatically adjust its position by the up and down movement of the piston to compensate for the tension change in real time. At the same time, since all cylinders share the same air pressure environment, the adjustment actions of each pulley are interconnected, ensuring that multiple yarns always maintain a uniform tension distribution during dynamic adjustment, which significantly improves the consistency of fiberglass yarn tension during the fiberglass cloth weaving process.

[0012] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0013] Example 1:

[0014] like Figure 1 , 2As shown in Figure 3, this utility model discloses a glass fiber yarn tension adjustment device, including a base 1. Mounting seats 6 are provided at both the front and rear ends of the base 1. A first roller 13 is rotatably mounted between the front mounting seats 6, and a second roller 7 is rotatably mounted between the rear mounting seats 6. The first roller 13 and the second roller 7 are at the same height and parallel to each other. An air storage tank 2 is fixedly mounted on the base 1 between the first roller 13 and the second roller 7. An air inlet pipe 4 is provided on the air storage tank 2, and an electromagnetic control valve 5 is provided on the air inlet pipe 4. A pressure transmitter is provided inside the air storage tank 2. Sensor 3, pressure sensor 3 and electromagnetic control valve 5 are electrically connected to a controller. The upper end of the gas storage tank 2 is provided with mounting holes at intervals along the length of the first roller 13. A cylinder 8 with the same inner diameter is vertically installed on the mounting holes. A piston 9 is slidably installed inside the cylinder 8. A piston rod 11 is provided at the upper end of the piston 9. The piston rod 11 is made of hollow plastic tube. An end cap 10 is provided at the upper end of the cylinder 8 for the piston rod 11 to pass through. The upper end of the piston rod 11 passes through the end cap 10. A fixed pulley 12 is provided at the upper end of the piston rod 11. The fixed pulley 12 is made of aluminum alloy.

[0015] The aforementioned device is installed between the fiberglass cloth weaving equipment and the yarn frame, so that each fiberglass yarn sequentially passes under the first roller 13, above the fixed pulley 12, and under the second roller 7, and is then fed into the fiberglass yarn weaving equipment. High-pressure gas is introduced into the air tank 2 through the air inlet pipe 4 connected to the high-pressure air pipe. The controller adjusts the opening and closing of the solenoid valve according to the data from the pressure sensor 3 to ensure that the air pressure reaches the set value. The high-pressure gas in the air tank 2 pushes the pistons 9 and piston rods 11 in the multiple vertically arranged cylinders 8 to move upward, and the fixed pulley 12 presses against the fiberglass yarn. When the tension of the glass fiber yarn fluctuates during the conveying process, that is, when the tension of the glass fiber yarn increases, the piston rod 11 and the fixed pulley 12 on the piston rod 11 descend to reduce the tension of the glass fiber yarn; when the tension of the glass fiber yarn decreases, the piston rod 11 and the fixed pulley 12 on the piston rod 11 rise to increase the tension of the glass fiber yarn. Since each cylinder 8 is connected to the air tank 2, the air pressure inside is consistent. Therefore, the fixed pulley 12 can effectively ensure the consistency of the tension of the glass fiber yarn in real time by floating up and down to adjust the tension of the glass fiber yarn.
