Description

Technical Field

[0001] The utility model relates to the technical field of spinning line detection devices, in particular to an adjustable spinning line detection device. Background Art

[0002] Spinning is a very ancient activity. Since prehistoric times, humans have known how to spin some shorter fibers into long yarns and then weave them into cloth. The so-called spinning is to take animal or plant fibers and twist them to make them into a continuous and infinitely extended yarn so that they are suitable for weaving. For example, the patent with publication number CN216889494U discloses an adjustable spinning line detection device, including a box body, the outer surface of the box body on both sides of which is symmetrically penetrated by two rectangular openings, the inner walls of the two rectangular openings are respectively rotatably installed with a conveying roller and a winding roller, the inner wall of the box body near the middle position thereof is fixedly installed with a support plate, the outer surface of the support plate is inserted with a threaded tube, the threaded tube penetrates the support plate and is threadedly connected to it, the inner wall of the threaded tube is slidably installed with a moving rod, and the bottom end of the moving rod is fixedly installed with a pressure sensor. The device sets a pressure sensor between the bottom end of the moving rod and the C-shaped frame so that the pressure sensor can detect the force that lifts the yarn upward. However, when the device is detecting, the conveyor roller is in a state of continuous rotation, and the pressure on the spinning line will drive the conveyor roller to rotate, which may buffer the spinning line, causing the pressure to fail to meet the detection standard. When the pressure on the spinning line is too great or the spinning line does not meet the standard, the spinning line may break and rebound, which may easily cause harm to the staff.

[0003] To this end, the utility model provides an adjustable spinning line detection device. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: an adjustable spinning line detection device, including a support frame 1, a winding roller 3 and a pay-off roller 4 are rotatably matched in the support frame 1, a rotating shaft is fixed to the axial center of the pay-off roller 4, both ends of the rotating shaft are threadedly matched with a fixing plate 7, a friction block 8 is installed on the fixing plate 7, a protective tube 13 is installed in the support frame 1, a sliding component is installed in the support frame 1, a telescopic component is installed between the sliding component and the protective tube 13, a pressure sensor 14 is fixed in the support frame 1, and the pressure sensor 14 corresponds to the sliding component.

[0022] In this embodiment, a motor 2 is fixed to one side of the support frame 1 , and an output end of the motor 2 is fixedly connected to the winding roller 3 .

[0023] Specifically, one end of the spinning line is passed through the protective tube 13 and wound around the winding roller 3, and then the motor 2 is started to wind the spinning line, thereby performing a pulling test on the spinning line.

[0024] Two grooves 9 are provided in the support frame 1, and a mounting block 5 is placed in the groove 9. The mounting block 5 is rotatably connected to the rotating shaft. Thread heads 6 are fixed at both ends of the rotating shaft. The thread heads 6 are located on the relatively outer sides of the support frame 1. A thread groove is provided in the fixing plate 7, and the thread groove corresponds to the thread head 6. The fixing plate 7 is fixedly connected to a friction block 8. The friction block 8 is an annular structure, and the friction block 8 is located on the side of the fixing plate 7 close to the support frame 1.

[0025] Specifically, when the detected pulling force needs to be changed, the fixed plate 7 is rotated so that the fixed plate 7 drives the friction block 8 to move toward the side close to the support frame 1. The friction between the friction block 8 and the support frame 1 increases, thereby increasing the force required to pull the spinning line, and the pulling force can be changed.

[0026] The sliding assembly includes a rodless cylinder 11 and multiple slide rails 10, and a slider 15 is slidably fitted on the slide rails 10. The telescopic assembly includes an electric cylinder 18 and multiple telescopic rods 16. The output end of the rodless cylinder 11 is fixedly connected to the electric cylinder 18, one end of the telescopic rod 16 is fixedly connected to the slider 15, the output end of the electric cylinder 18 is fixedly connected to the protective tube 13, and the other end of the telescopic rod 16 is fixedly connected to the protective tube 13.

[0027] An infrared distance sensor is installed in the support frame 1 to detect the position of the spinning line, and then the rodless cylinder 11 is controlled to start according to the position of the spinning line, thereby pushing the protection tube 13 to move, so that the protection tube 13 always matches the position of the spinning line.

[0028] When fixed-point detection is required, the fixed plate 7 is rotated to lock the pay-off roller 4, and then the electric cylinder 18 is started. The electric cylinder 18 drives the protective tube 13 to move, thereby pulling the spinning line. The pressure sensor 14 can detect the pulling force, and the positioning detection of the spinning line can be realized.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
