Description

Technical Field

[0001] This utility model relates to the field of visibility meters, and in particular to a cotton thread tension detection device. Background Technology

[0002] In textile processing, the stability of cotton yarn tension has a significant impact on yarn quality, fabric structure, and equipment operating efficiency. To achieve real-time monitoring and control of cotton yarn tension, tension detection devices are typically installed along the processing path. However, most existing detection devices require the cotton yarn to pass through key internal components before processing can begin. This means the detection device must be installed before processing begins and the yarn threading operation must be completed. It is impossible to connect the detection device during processing, leading to production interruptions when replacing or maintaining the device, thus affecting continuous equipment operation efficiency. Therefore, this paper proposes a cotton yarn tension detection device to solve these problems. Utility Model Content

[0003] The main purpose of this utility model is to provide a cotton thread tension detection device to solve the problem that the detection device cannot be connected at any time during the processing, which leads to the interruption of the production process when the detection device is replaced or maintained, thus affecting the continuous operation efficiency of the equipment.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a cotton thread tension detection device, including a mounting base and a rotating arm arranged parallel to it. The mounting base is provided with a mounting bearing that passes through it. A rotating shaft connected to the tail end of the rotating arm is rotatably arranged in the rotating bearing. A rotating drive device is also provided on the back of the mounting base. The rotating drive device includes a drive motor whose output end is connected to the rotating shaft, and an encoder mounted on the drive motor. The rotating arm passes through a hinge groove provided at its front end. A wheel seat is provided in the hinge groove and hinged to it through a hinge ear. A pressing wheel for pressing down the cotton thread is rotatably arranged in the wheel seat. An arc-shaped groove is provided on the inner side of the hinge groove. A pressure sensor is provided at the bottom of the arc-shaped groove. A limiting block is provided on the outer side of the hinge ear of the wheel seat and moves in cooperation with the arc-shaped groove. The limiting block can contact the pressure sensor.

[0005] In a preferred embodiment, a support platform for supporting the rotary drive device is also provided on the back of the mounting base.

[0006] In the preferred embodiment, the front of the mounting base is provided with a locking structure for locking the rotating arm in its initial state;

[0007] The locking structure includes a locking disc disposed outside the rotating shaft, with a locking notch at the edge of the locking disc, and a self-locking component that can cooperate with the locking notch on the front of the mounting base.

[0008] In the preferred embodiment, the self-locking component includes a support plate disposed on the front of the mounting base, a telescopic cylinder mounted on the top of the support plate, a locking block mounted through the telescopic end of the telescopic cylinder, the locking block being able to cooperate with the locking notch, and two telescopic rods being movably disposed through the support plate, the bottom end of the telescopic rods being connected to the locking block, and a limit plate being disposed on the top.

[0009] In the preferred embodiment, a height adjustment frame is also included. The height adjustment frame is symmetrically provided with lifting slides on both sides. The mounting base is symmetrically provided with sliding screws that move through the lifting slides on both sides. The protruding end of the sliding screw is threaded with a locking nut.

[0010] In the preferred embodiment, an internally threaded shaft is provided at the center of the top of the height adjustment frame, and a lifting adjustment screw is threaded in the internally threaded shaft. The bottom end of the lifting adjustment screw is rotatably connected to the top of the mounting base, and a rotating handle is provided at the top end of the lifting adjustment screw.

[0011] In the preferred embodiment, a rotating connecting seat is provided on the top of the mounting base, and a T-shaped rotating head that rotates in conjunction with the rotating connecting seat is provided at the bottom of the lifting and adjusting screw.

[0012] In the preferred embodiment, the mounting base at the bottom of the height adjustment frame is provided with multiple mounting holes for fixing.

[0013] This invention provides a cotton thread tension detection device. A rotatable rotating arm is mounted on a mounting base, and a hinged wheel seat structure with a pressure roller is configured at the front end of the rotating arm. This allows the pressure roller to precisely press down on the cotton thread under motor drive. Simultaneously, an encoder provides real-time feedback of the rotation angle, enabling precise control and calculation of tension changes. Furthermore, an arc-shaped groove and a limiting block are designed within the hinged groove, combined with a pressure sensor, to monitor the contact state between the pressure roller and the cotton thread in real time, improving detection accuracy and stability. Compared to existing technologies, this device eliminates the need to pre-insert the detection equipment into the cotton thread path before processing begins; instead, it can be quickly deployed from the side during cotton thread operation, significantly improving detection flexibility and equipment maintenance efficiency. Moreover, in non-detection states, the pressure roller can be disengaged from the cotton thread path, avoiding interference with normal production processes. Attached Figure Description

[0022] Example 1

[0023] like Figure 1-4 As shown, a cotton thread tension detection device includes a mounting base 1 and a rotating arm 4 arranged parallel to it. The mounting base 1 is provided with a mounting bearing 2 that passes through it. A rotating shaft 3 connected to the tail end of the rotating arm 4 is rotatably arranged in the rotating bearing 2. A rotating drive device 6 is also provided on the back of the mounting base 1. The rotating drive device 6 includes a drive motor 601 whose output end is connected to the rotating shaft 3, and an encoder 602 mounted on the drive motor 601. Thus, the rotating arm 4 can be driven to rotate by the rotating drive device 6, and its rotation angle can be recorded by the encoder 602.

[0024] The rotating arm 4 is connected to a hinge groove 401 at its front end. A wheel seat 501 is hinged to the hinge groove 401 via a hinge ear. The hinge ear is hinged to the hinge groove 401 via a shaft. A pressing wheel 5 for pressing down cotton thread is rotatably mounted in the wheel seat 501. An arc-shaped groove 402 is provided on the inner side of the hinge groove 401. The arc-shaped groove 402 is specifically located on the inner side of the middle part of the hinge groove 401. A pressure sensor 403 is provided at the bottom of the arc-shaped groove 402. A limiting block 502 is provided on the outer side of the hinge ear of the wheel seat 501, which is movably engaged with the arc-shaped groove 402. The engagement of the limiting block 502 with the arc-shaped groove 402 can limit the rotation angle of the wheel seat 501 and the pressing wheel 5, and the limiting block 502 can contact the pressure sensor 403.

[0025] In use, when the rotating arm 4 is initially raised, the wheel seat 501 and the pressing wheel 5 droop under the action of gravity. At the same time, the limiting block 502 and the top of the arc groove 402 abut against each other to achieve the effect of limiting the drooping. As the rotating arm 4 begins to rotate downward, the pressing wheel 5 rotates after contacting the horizontal cotton thread until the limiting block 502 abuts against the pressure sensor 403 at the bottom of the arc groove 402. At this time, the signal transmitted by the pressure sensor 403 indicates that the pressing wheel 5 is in contact with the cotton thread. The pressing wheel 5, which droops by gravity alone, will not affect the tension detection structure of the cotton thread. At this time, the rotating arm 4 continues to rotate downward, and the encoder 602 records the rotation angle at this time. Then, the corresponding tension value can be obtained by the final rotation angle.

[0026] This design allows the detection device to be moved from the side to above the cotton thread during inspection, and the pressure roller 5 can be aligned with the cotton thread to complete the deployment of the device. This eliminates the need to install and deploy the device before processing begins. Furthermore, the device can be disassembled and reassembled for maintenance without stopping the machine. The downward-hanging pressure roller 5 prevents it from having to maintain a constant contact with the cotton thread, which would affect the normal processing of the cotton thread. In addition, the pressure sensor 403 can sense the contact status between the pressure roller 5 and the cotton thread.

[0027] It should be noted that the data table corresponding to the rotation angle of the rotating arm and the tension value can be obtained through an experimental calibration method. Specifically, during the experimental calibration process, the rotating arm is driven by a controlled motor to press down the cotton thread, and the rotation angle is accurately measured using an encoder. At the same time, standard weights are used to simulate different tensions. The angle value corresponding to each tension is recorded, and an "angle-tension" data table is established. This is a commonly used experimental method, so it will not be described in detail here. In addition, the length of the rotating arm can be adjusted according to the tension detection needs. The pressing wheel 5 is a wheel with a groove in the middle to prevent the cotton thread from detaching during the detection process.

[0028] In a preferred embodiment, the back of the mounting base 1 is also provided with a support platform 7 for supporting the rotary drive device 6, thereby improving the stability of the rotary drive device 6 during installation.

[0029] In the preferred embodiment, the front of the mounting base 1 is provided with a locking structure 8 for locking the initial state of the rotating arm 4. The locking structure 8 can keep the rotating arm 4 in its initial cantilever state before the test, thereby improving its structural stability.

[0030] The locking structure 8 includes a locking disc 801 disposed outside the rotating shaft 3. The locking disc 801 has a locking notch 802 at its edge. The mounting base 1 has a self-locking component that can cooperate with the locking notch 802 on its front side.

[0031] The self-locking assembly includes a support plate 803 disposed on the front of the mounting base 1. A telescopic cylinder 807 is mounted on the top of the support plate 803. A locking block 805 is mounted through the telescopic end of the telescopic cylinder 807 through the support plate 803. The locking block 805 can cooperate with the locking notch 802. Two telescopic rods 804 are movably disposed through the support plate 803. The bottom end of the telescopic rod 804 is connected to the locking block 805, and a limit plate 806 is disposed on the top. The telescopic cylinder 807 can be a pneumatic cylinder or an electric cylinder, and its telescopic length meets the requirement of the locking block 805 cooperating with the locking notch 802.

[0032] With this design, the locking block 805 can be extended and retracted by the telescopic cylinder 807, and the telescopic rod 804 can effectively ensure the stability of the extension and retraction of the locking block 805. Thus, by using the cooperation between the locking block 805 and the locking notch 802, the posture of the rotating arm 4 can be locked.

[0033] Example 2

[0034] Further explanation in conjunction with Example 1, such as Figure 5-6 As shown in the embodiment, the height adjustment frame 11 is a rectangular frame structure, and its bottom is provided with a mounting base with a width greater than that of the structure above. The height adjustment frame 11 is provided with lifting slide grooves 12 symmetrically on both sides. The mounting base 1 is provided with sliding screws 10 that move through the lifting slide grooves 12 symmetrically on both sides. The protruding end of the sliding screws 10 is threaded with a locking nut 16.

[0035] With this design, the device can be placed at the detection point via the height adjustment frame 11, and the height of the device can be adjusted by sliding the mounting base 1 sliding screw 10 up and down in the lifting slide 12. At the same time, the height can be locked by tightening the locking nut 16.

[0036] In the preferred embodiment, an internal threaded shaft 13 is provided at the center of the top of the height adjustment frame 11, and a lifting adjustment screw 14 is threaded in the internal threaded shaft 13. The bottom end of the lifting adjustment screw 14 is rotatably connected to the top of the mounting base 1, and a rotating handle 15 is provided at the top end of the lifting adjustment screw 14.

[0037] This design allows for height adjustment by rotating the lifting adjustment screw 14 after the locking nut 16 is released, ensuring the accuracy of height adjustment and preventing unnecessary slippage after adjustment.

[0038] The rotatable connection method is as follows: the top of the mounting base 1 is provided with a rotating connecting seat 9, and the bottom of the lifting adjustment screw 14 is provided with a T-shaped rotating head 17 that rotates and cooperates with the rotating connecting seat 9. The T-shaped structure achieves rotatability while ensuring connectivity.

[0039] In the preferred embodiment, the mounting base at the bottom of the height adjustment frame 11 is provided with multiple mounting holes 18 for fixing, so that the device can be fixed at the installation position by bolts.

[0040] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
