Description

Technical Field

[0001] This invention relates to the field of glass fiber manufacturing technology, and in particular to a glass fiber drawing tension detection and adjustment device and its detection and adjustment method. Background Technology

[0002] Tank furnace drawing is a major process in glass fiber production, and its principle is as follows: Figure 1 As shown, the system includes a furnace, oiling system, bundling system, and drawing system. During glass fiber drawing, the rotation of the drawing machine drum pulls the fiber bundle out at a constant linear speed. Therefore, the linear speed of the fiber bundle is a crucial parameter affecting the drawing effect, requiring high control precision. Practice shows that the tension of the fiber bundle also has a significant impact, affecting not only the quality of the drawn fiber but also the formation of the fiber cake. However, existing drawing systems cannot accurately control and detect the tension of the fiber bundle, and they cannot automatically monitor fiber bundle breakage for various reasons, relying mainly on manual inspection.

[0003] To address this issue, a glass fiber drawing tension detection and adjustment device and its detection and adjustment method are designed to provide an alternative technical solution for the aforementioned technical problems. Summary of the Invention

[0004] Therefore, it is necessary to provide a glass fiber drawing tension detection and adjustment device and its detection and adjustment method to address the aforementioned technical problems.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A glass fiber drawing tension detection and adjustment device includes a sliding member, a waterproof slide platform slidably connected to the top of the sliding member, a bracket seat bolted to the top of the waterproof slide platform, a connecting block fixed to one end of the top of the bracket seat, a positioning bracket rotatably connected to the inner side of the top of the connecting block, a bearing seat fixed to the top of the positioning bracket, a waterproof stepper motor fixed to one side of the bearing seat, a bundled disk fixed to the output end of the waterproof stepper motor and located on the other side of the bearing seat, a tension / compression sensor slidably connected to the bottom of one end of the positioning bracket, the bottom of the tension / compression sensor being threadedly connected to the bracket seat, a spring fixed to the top of one end of the positioning bracket and located outside the tension / compression sensor, and a fixing nut threadedly connected to the outside of the tension / compression sensor and located at the top of the spring.

[0007] In a preferred embodiment of the glass fiber drawing tension detection and adjustment device provided by the present invention, a displacement plate is fixed on one side of the waterproof slide, and a laser photoelectric switch sensor is fixed on one side of the sliding member.

[0008] In a preferred embodiment of the glass fiber drawing tension detection and adjustment device provided by the present invention, the laser photoelectric switch sensor is model LQT-31NONPN.

[0009] A method for detecting and adjusting the tension of glass fiber drawing, used for any of the above, comprises the following steps:

[0010] S1: Analyze the forces acting on the cluster disk;

[0011] S2: Calculate the moving distance of the waterproof slide.

[0012] In a preferred embodiment of the glass fiber drawing tension detection and adjustment method provided by the present invention, in step S1, the force on the bundle disk is analyzed, and the expression is as follows:

[0013] F 压 =2F 拉 cosα

[0014] F 压 xL2=F 测 xL1

[0015] Get F 拉 =0.5cosα(L1 / L2)F 测

[0016] Where F_tension is the pulling force, F_compression is the pressure exerted by the glass fiber bundle on the bundled disk, and F_measurement is the force measured by the tension and compression sensor;

[0017] By F 压 xL2=F 测 xL1 yields F 测 =F 压 (L2 / L1).

[0018] In a preferred embodiment of the glass fiber drawing tension detection and adjustment method provided by the present invention, in step S2, the moving distance of the waterproof slide is calculated, as shown in the following expression:

[0019]

[0020] Where S is the adjustment displacement distance of the waterproof sliding platform.

[0021] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0022] Meanwhile, through the above technical solutions, the present invention has at least the following beneficial effects:

[0023] The present invention provides a glass fiber drawing tension detection and adjustment device and its detection and adjustment method. The operation of the sliding component can drive the positioning bracket to move, and the reaction force of the glass fiber bundle on the bundle disk can cause the bundle disk to squeeze the tension and pressure sensor through the positioning bracket, thereby detecting the tension of the glass fiber bundle. At the same time, it can provide an alarm through the feedback of the tension and pressure sensor when the glass fiber bundle breaks.

[0024] Through improvements in the detection and adjustment methods, the tension of the glass fiber bundle can be calculated during use. After calculation, the movement distance of the waterproof slide can be controlled. Furthermore, an alarm device can be used to alert staff when the glass fiber bundle breaks, based on feedback from the tension and pressure sensors. Attached Figure Description

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] Example 1

[0039] Reference Figures 2-4 A glass fiber drawing tension detection and adjustment device includes a sliding member 1. A waterproof slide 2 is slidably connected to the top of the sliding member 1, so that the sliding member 1 can drive the waterproof slide 2 to slide horizontally during operation, thereby making the movement of the waterproof slide 2 smooth and moving by electric means. A bracket 3 is bolted to the top of the waterproof slide 2. A connecting block 4 is fixed to one end of the top of the bracket 3. A positioning bracket 5 is rotatably connected to the inner side of the top of the connecting block 4, so that the connecting block 4 and the positioning bracket 5 are rotatably connected by a pin, and the positioning bracket 5 can rotate around the top of the connecting block 4 with the pin as the center. A bearing seat 11 is fixed to the top of the positioning bracket 5. A waterproof stepper motor 9 is fixed to one side of the bearing seat 11. A bundled disk 10 is fixed to the output end of the waterproof stepper motor 9 and located on the other side of the bearing seat 11, so that the operation of the waterproof stepper motor 9 can drive the bundled disk 10 to rotate, thereby placing the glass fiber bundle outside the bundled disk 10, and the movement of the bundled disk 10 can adjust the tension of the glass fiber bundle.

[0040] In other embodiments, the slider 1 consists of a servo motor, a lead screw, and a housing, so that the servo motor can drive the lead screw to rotate, allowing the waterproof slide 2 to slide horizontally on the outer side of the top of the housing, while the slider 1 and the waterproof slide 2 are combined to form a waterproof module kit.

[0041] A tension / compression sensor 6 is slidably connected to the bottom of one end of the positioning bracket 5, allowing the tension / compression sensor 6 to slide upwards on the inner side of one end of the positioning bracket 5. The positioning bracket 5 rotates slightly on the outer side of the tension / compression sensor 6 through the rotational connection with the connecting block 4, thus compressing the tension / compression sensor 6. At the same time, a through hole is opened inside the positioning bracket 5 on the outer side of the tension / compression sensor 6, and the diameter of the through hole is larger than the diameter of the top of the tension / compression sensor 6, allowing the positioning bracket 5 to slide on the outer side of the top of the tension / compression sensor 6, but compressing the bottom of the tension / compression sensor 6. The bottom of the tension / compression sensor 6 is threadedly connected to the bracket base 3. A spring 8 is fixed at the top of one end of the positioning bracket 5 on the outer side of the tension / compression sensor 6, and a fixing nut 7 is threadedly connected to the outer side of the tension / compression sensor 6 on the top of the spring 8. The fixing nut 7 is threadedly connected to the tension / compression sensor 6, and the compression of the spring 8 by the fixing nut 7 brings the positioning bracket 5 and the tension / compression sensor 6 into close contact, so that the force on the positioning bracket 5 can directly compress the tension / compression sensor 6.

[0042] A displacement plate 12 is fixed on one side of the waterproof slide 2, and a laser photoelectric switch sensor 13 is fixed on one side of the sliding member 1, allowing the displacement plate 12 to move inside the top of the laser photoelectric switch sensor 13. Specifically, the laser photoelectric switch sensor 13 is model LQT-31NONPN, so that when the movement of the waterproof slide 2 passes inside the laser photoelectric switch sensor 13, the laser photoelectric switch sensor 13 can detect the movement of an object and then transmit the signal to the external display screen.

[0043] In this embodiment, an operation module is also included, which transmits the detection signal of the tension / compression sensor 6 to the operation module, and allows the operator to control the operation of the slider 1 based on the detection signal of the tension / compression sensor 6 by manually controlling the operation module.

[0044] This embodiment provides a glass fiber drawing tension detection and adjustment device. In use, the glass fiber bundle is positioned outside the bundled disk 10, with the waterproof stepper motor 9 electrically connected to an external power source. When the waterproof stepper motor 9 operates, it drives the bundled disk 10 to rotate, resulting in more even oiling of the glass fiber bundle and uniform friction on the bundled disk. This movement, via the sliding member 1, moves the waterproof slide table 2, causing the waterproof slide table 2 to move via the connecting block 4, which in turn moves the rotatably connected positioning bracket 5. The movement of the positioning bracket 5, through the bearing seat 11, drives the bundled disk 10, thereby adjusting the tension of the glass fiber bundle. Further movement of the positioning bracket 5 then adjusts the tension of the glass fiber bundle. As the glass fiber bundle gradually tightens, it exerts a reaction force on the bundled disc 10, causing the bundled disc 10 to rotate around the bearing seat 11 and the positioning bracket 5, with the rotation connection of the connecting block 4 as the center. This rotation of the positioning bracket 5 causes the bottom of the tension / compression sensor 6 to contact the bracket seat 3. The tension / compression sensor 6 can then detect the tension of the glass fiber bundle. If the value of the tension / compression sensor 6 exceeds the highest set threshold, it indicates that the tension of the glass fiber bundle is too tight. If the value of the tension / compression sensor 6 is lower than the lowest set threshold, it indicates that the glass fiber bundle has broken, and personnel are notified to conduct manual inspection.

[0045] Example 2

[0046] Reference Figures 5-7 Based on the above embodiment one, its detection and adjustment method is disclosed.

[0047] The forces acting on the cluster disk 10 are analyzed, and the expression is as follows:

[0048] F 压 =2F 拉 cosα (1)

[0049] F 压 xL2=F 测 xL1 (2)

[0050] F can be obtained 拉 =0.5cosα(L1 / L2)F 测 ;

[0051] Wherein, F_pull is the pulling force, F_compression is the pressure exerted by the glass fiber bundle on the bundled disk 10, and F_measurement is the force measured by the tension and compression sensor 6;

[0052] From Equation 2, we can obtain F 测 =F 压 (L2 / L1), it can be seen that the pressure of the bundle disk 10 is amplified by L2 and L1 to solve the problem of low detection accuracy caused by insufficient wire drawing force;

[0053] Depend on Figure 6 It can be obtained. Therefore, when the waterproof sliding platform 2 adjusts the displacement S, the angle α can be adjusted. In practical applications, adjusting α adjusts the wrap angle of the glass fiber bundle on the bundled disk 10, changing the pressure of the glass fiber bundle on the bundled disk 10, thereby changing the friction between the glass fiber bundle and the bundled disk 10, ultimately changing the tension of the glass fiber bundle, and thus determining the optimal tension of the glass fiber bundle.

[0054] like Figure 5 As shown, the wire drawing force and fault signals can be set through the human-machine interface. The input parameters are processed by the programmable controller and its detection and adjustment device (Example 1) to determine the optimal wire drawing force. The tension and pressure signals provide tension signals to adjust and determine the wire drawing force. When the tension and pressure are at their minimum values, it indicates that the wire bundle is broken. The programmable controller then sends a wire breakage alarm to the alarm device to notify the staff.
