Description

Technical Field

[0001] The utility model relates to the technical field of tension detection, in particular to a fiber line tension detection device. Background Art

[0002] The working principle of the fiber line tension detection device is based on the concept of tension in physics. Tension refers to the resistance generated by the internal structure of an object when it is subjected to a pulling force. The device calculates the tension value by measuring the pulling force on the fiber line. The device usually contains a measuring device and a display device. The measuring device consists of a spring and a sensor. The sensor is responsible for sensing the pulling force on the fiber line and converting it into an electrical signal to output to the display device. The display device converts the electrical signal into a tension value and displays it on the screen.

[0003] At present, the most commonly used fiber line tension sensor is a three-pulley tension sensor to realize the detection of fiber line tension. However, this three-pulley tension sensor is mostly handheld. During sampling detection, since the completed fiber lines are all rolled on vertical drums, it is necessary to manually or with the help of tools to randomly pull the sampled fiber line rolls at a fixed distance so that the detection part is located between the three pulleys. However, since each roll of fiber line will be tested dozens to hundreds of times, it is completely done manually, which is inefficient and easily leads to inaccurate data collection. Therefore, a fiber line tension detection device is proposed. Utility Model Content

[0004] The purpose of the present utility model is to solve the shortcomings existing in the prior art. When performing sampling inspection, since the completed fiber lines are all rolled on the vertical drum, it is necessary to manually or with the help of tools to randomly pull the sampled fiber line rolls at a fixed distance so that the detection part (fiber line) is located between the three pulleys. However, since each roll of fiber line will be tested dozens to hundreds of times, it is completely done manually, which is inefficient and easily leads to inaccurate data collection.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A fiber line tension detection device includes a three-pulley tension sensor and a detection platform. The three-pulley tension sensor is connected to an external controller and is mounted on the detection platform. A thread feeding mechanism and a winding mechanism are respectively mounted on both sides of the shorter side of the detection platform. A guide cover is provided between the top of the detection platform and the thread feeding mechanism and the winding mechanism.

[0007] The thread-up mechanism includes a first support, a first rotating shaft, and a first positioning plate. The first support is fixed to the side of the detection platform near the back, and has the first rotating shaft parallel to the shorter side of the detection platform. There are two first positioning plates, which are threadedly connected to the first threaded portions at both ends of the first rotating shaft.

[0008] The winding mechanism includes a second support, a second rotating shaft, and a second positioning disk. The second support is fixed to the side of the detection platform near the front side and has a second rotating shaft parallel to the shorter side of the detection platform. There are two second positioning disks, which are threadedly connected to the second threaded portions at both ends of the second rotating shaft.

[0009] The two ends of the guide cover correspond to the through-design of the thread-up mechanism and the winding mechanism. The two sides of the interior of the guide cover are symmetrically designed in a stepped manner. A guide roller is installed on each step plane. The guide rollers on both sides near the three-pulley tension sensor are at the same height as the wire grooves of the three-pulley tension sensor pulleys.

[0010] Furthermore, the pulleys of the three-pulley tension sensor are arranged horizontally and on the same horizontal line as the detection platform.

[0011] Furthermore, the first rotating shaft is rotatably connected to the first support via a shaft seat.

[0012] Furthermore, a servo motor is installed on the outer side of the second support, and the second rotating shaft is installed at the output end of the servo motor.

[0013] Furthermore, rubber pads are bonded to the inner sides of the first positioning plate and the second positioning plate.

[0014] Furthermore, the guide rollers on both sides of the guide cover, which are symmetrically stepped and close to the thread-feeding mechanism or the winding mechanism, are at the same height as the central axis of the first rotating shaft or the second rotating shaft.

[0015] Furthermore, the guide rollers are made of stainless steel rollers, both ends of which are rotatably connected to the guide cover, and a built-in groove is opened on the stepped plane corresponding to each guide roller for the built-in of the guide roller.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By introducing a winding mechanism driven by a servo motor, the fiber line can be automatically wound and unwound, which greatly reduces manual operation and improves inspection efficiency. Especially in cases where frequent inspections are required dozens to hundreds of times, automated operation significantly improves work efficiency.

[0018] At the same time, the automated winding and unwinding process reduces errors caused by human factors, making the tension and position of the fiber line more stable during each inspection, thereby improving the accuracy of data collection.

[0019] The guide cover and the stepped guide roller ensure that the fiber line is guided into the pulley of the three-pulley tension sensor, ensuring smooth operation during the detection process and avoiding friction and entanglement between the fiber line and other parts of the device.

[0020] Finally, the positions of the first positioning disc and the second positioning disc connected by threads can be conveniently adjusted to accommodate fiber coils of different diameters.

[0021] In summary, the fiber line tension detection device provided by the present invention shows significant advantages in improving detection efficiency, increasing data accuracy and adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] Example 1

[0036] like Figure 1-3 As shown, the utility model provides a technical solution: the fiber line tension detection device of this embodiment includes a three-pulley tension sensor 1 and a detection platform 2. The three-pulley tension sensor 1 is connected to an external controller. This device is not only suitable for the three-pulley tension sensor 1, but can also be appropriately adjusted as needed to adapt to other types of tension detection sensors.

[0037] It is installed on the detection platform 2, which provides a stable support base for the entire device. A thread-feeding mechanism 3 and a winding mechanism 4 are respectively installed on both sides of the shorter side of the detection platform 2. A guide cover 5 is provided between the top of the detection platform 2 and the thread-feeding mechanism 3 and the winding mechanism 4.

[0038] The thread-up mechanism 3 includes a first support 31, a first rotating shaft 32 and a first positioning disk 33. The first support 31 is fixed on the side of the detection platform 2 near the back, and a first rotating shaft 32 is parallel to the shorter side of the detection platform 2. There are two first positioning disks 33, which are threadedly connected to the first threaded parts 34 at both ends of the first rotating shaft 32. The first positioning disk 33 is used to fix the fiber line roll by rotating the position (spacing) between the first threaded parts 34.

[0039] The winding mechanism 4 includes a second support 41, a second rotating shaft 42, and a second positioning disk 43. The second support 41 is fixed to the side of the detection platform 2 near the front, and the second rotating shaft 42 is parallel to the shorter side of the detection platform 2. There are two second positioning disks 43, which are threadedly connected to the second threaded portions 44 at both ends of the second rotating shaft 42. Similarly, the second positioning disks 43 are rotated to the position (spacing) between the second threaded portions 44 to fix the fiber coil;

[0040] The two ends of the guide cover 5 correspond to the through-design of the thread-feeding mechanism 3 and the winding mechanism 4. The two sides of the inside of the guide cover 5 are symmetrically stepped. A guide roller 51 is installed on each step plane. The guide rollers 51 on both sides near the three-pulley tension sensor 1 are at the same height as the wire grooves of the pulleys of the three-pulley tension sensor 1 to ensure the smooth operation of the fiber line during the detection process.

[0041] Example 2

[0042] like Figure 1-3 As shown, this embodiment further optimizes and refines the device based on Example 1;

[0043] The pulleys of the three-pulley tension sensor 1 are arranged horizontally and on the same horizontal line as the detection platform 2, and are used to measure the tension of the fiber line.

[0044] The first rotating shaft 32 is rotatably connected to the first support 31 through a shaft seat; a servo motor 45 is installed on the outer side of the second support 41, and the second rotating shaft 42 is installed on the output end of the servo motor 45.

[0045] Among them, the first rotating shaft 32 is rotatably connected to the first support 31 through the shaft seat, and the second rotating shaft 42 is installed at the output end of the servo motor 45. The operation of the servo motor 45 drives the second rotating shaft 42 to rotate, and then drives the first rotating shaft 32 to rotate, realizing automatic operation.

[0046] Rubber pads 6 are bonded to the inner sides of the first positioning disc 33 and the second positioning disc 43 to increase friction with both ends of the fiber coil and ensure stable clamping.

[0047] The guide rollers 51 symmetrically arranged in stepped portions on both sides of the guide cover 5 close to the thread-up mechanism 3 or the winding mechanism 4 are at the same height as the central axis of the first rotating shaft 32 or the second rotating shaft 42 .

[0048] The guide roller 51 is a stainless steel roller, and both ends are rotatably connected to the guide cover 5. A built-in groove 52 is opened on the stepped plane corresponding to each guide roller 51 for embedding the guide roller 51.

[0049] The working process of the present utility model is as follows: when using a fiber line tension detection device, it is first necessary to fix the fiber line roll between the two first positioning disks 33 and the two second positioning disks 43 of the online mechanism 3 and the winding mechanism 4 respectively. The fiber line roll fixed on the online mechanism 3 is the roll to be detected, and the fiber line roll fixed on the winding mechanism 4 is an empty roll (vertical drum). The thread head of the roll to be detected is wound onto the second rotating shaft 42 through the guide cover 5 and the three-pulley tension sensor 1. The second rotating shaft 42 is driven to rotate by the servo motor 45 to make the winding mechanism 4 start to wind. The fiber line passes through the guide roller 51 inside the guide cover 5 and smoothly enters the measuring area of ​​the three-pulley tension sensor 1. The three-pulley tension sensor 1 transmits the measured tension value to the external controller for data processing and display. The empty roll (vertical drum) on the second rotating shaft 42 is wound. During the whole process, the guide cover 5 and the guide roller 51 ensure the smooth operation and accurate measurement of the fiber line.

[0050] It should be noted that tension detection generally detects standard tension. At least this device detects the standard value of fiber line tension. If the product is qualified, it will generally not break. When a break occurs, it means that the fiber line roll is unqualified and a new roll is required for testing.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
