Description

Technical Field

[0001] This utility model relates to the field of textile equipment testing technology, and in particular to a yarn tube chassis flatness testing device. Background Technology

[0002] Yarn tubes are core equipment used for winding yarn in textile production. The flatness of their base directly affects the winding quality of the yarn and the stability of subsequent weaving processes. If the base of the yarn tube is not flat, it will cause uneven yarn winding and yarn bobbin jumping when used on equipment such as twisting machines, which will lead to problems such as yarn breakage and yarn defects. In severe cases, it will cause the yarn tube to be scrapped, increasing production costs.

[0003] In existing technologies, the flatness of the yarn tube base is mostly tested using a desktop testing method: the yarn tube is placed on a horizontal table, and its flatness is determined by manually using a ruler or simple measuring tools. This method has the following significant drawbacks: First, the detection benchmark is inconsistent with the spindle parameters of the actual production equipment (such as a twisting machine), making it difficult to accurately control the levelness of the workbench, resulting in inaccurate judgments. Some yarn tubes that pass the test on the workbench still exhibit jumping problems after being installed on the twisting machine spindle. Second, the detection method is a single-station independent operation, which cannot achieve simultaneous multi-station testing. Operators must complete the placement, positioning, measurement, and removal of each yarn tube one by one, resulting in extremely low detection efficiency and making it difficult to meet the testing needs of textile enterprises for dozens or even hundreds of yarn tubes at a time in batch production. Third, the detection accuracy depends on the operator's experience, is highly subjective, and has a large error. In the single-station detection mode, operators are prone to fatigue due to repetitive single actions for a long time, which further amplifies the detection error. Fourth, although some improvement schemes attempt to increase the number of detection stations, the problems of benchmark consistency and operational interference between multiple stations are not resolved, resulting in large differences in the detection results of different stations and making it impossible to guarantee the reliability of the detection data. Therefore, there is an urgent need for a yarn tube chassis flatness detection device that can simulate actual production conditions, provide accurate detection, and enable multi-station detection, in order to overcome the shortcomings of existing technologies.

Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example like Figure 1 As shown, this embodiment provides a yarn tube base flatness detection device, including: a central platform 1 and four detection stations 2. The four detection stations 2 are symmetrically distributed in a cross shape along the circumference of the central platform 1. A spindle 3 is fixedly installed on the detection station 2, and the upper surface of the spindle 3 is a horizontal detection reference surface. A dial indicator 4 corresponding to each detection station 2 is set on the central platform 1. The height of the central platform 1 is greater than the height of the detection station 2 to form an interference-free vertical detection space.

[0023] In this embodiment, the included angle between two adjacent testing stations 2 is 90°. This distribution method ensures that the operator has no movement interference during the testing process, and maximizes the use of the space occupied by the equipment. It can simultaneously test four groups of yarn tubes, which greatly improves the efficiency of batch testing.

[0024] In this embodiment, the detection station 2 is a horizontal square platform 21. A spindle 3 is fixedly installed on the upper surface of the horizontal square platform 21. The parameters of the spindle 3 are completely consistent with those of the spindle normally used on the twisting machine. Its upper surface is a horizontal detection reference surface, simulating the actual working state of the yarn tube.

[0025] There are several ways to fix the inspection station 2: For example, in this embodiment, the testing station 2 can be directly fixed to the ground by pre-embedded fasteners. In this case, a gap can be left between the four testing stations 2 and the central platform 1.

[0026] Alternatively, leveling bolts can be installed at the bottom of inspection station 2. By rotating the leveling bolts, the levelness of the horizontal square platform 21 can be precisely adjusted to ensure that the inspection reference surface is flat. Each leveling bolt is equipped with a double-nut locking structure (two locking nuts, one above and one below). After the horizontal square platform 21 is adjusted to a horizontal state by adjusting the leveling bolts, tighten the locking nut on the lower side to lock it with the screw of the leveling bolt, preventing the leveling bolt from rotating due to vibration, ensuring long-term stability of the levelness, and no significant changes during continuous use.

[0027] In this embodiment, the central platform 1 includes a lower base 11, a column 12, and an upper fixed seat 13. The column 12 is a square column structure, with its lower end welded to the lower base 11 and its upper end welded to the upper fixed seat 13. The lower base 11 consists of a lower fixed plate 111 and four rectangular steel plate limiting plates 112, which are welded to the lower fixed plate 111 in a cross pattern. The upper fixed seat 13 is an octagonal fixed plate with four universal joint rod bracket mounting positions along the cross-symmetrical direction. Each mounting position is equipped with a universal joint rod bracket 5 through a flange fixing sleeve, and the universal joint rod bracket 5 corresponds one-to-one with the detection station 2.

[0028] In this embodiment, a slot is provided on one side of the inspection station 2. The slot is adapted to be inserted into the limiting plate 112 to fix the inspection station 2 and prevent displacement during the inspection process. Specifically, the limiting plate 112 can be inserted into the inspection station 2 along the slot. In this way, when the inspection station 2 adjusts its distance from the central platform 1, it can move along the length of the limiting plate 112, always maintaining the four inspection stations 2 in a cross-shaped symmetrical distribution along the circumference of the central platform 1, thus avoiding interference.

[0029] In this embodiment, the universal joint rod support 5 can use an existing form or adopt the following structure: The universal joint rod support 5 is made of high-strength aluminum alloy, combining lightweight and high strength characteristics, covering the central area of ​​the detection station 2. Its specific structure includes a fixed joint, an intermediate adjusting joint, and an end-effector joint. The joints are connected by ball joints to achieve multi-dimensional angle adjustment. The adjustment range is as follows: 360° rotation in the horizontal direction and ±45° swing in the vertical direction, meeting the detection requirements of yarn tubes of different specifications. The universal joint rod support 5 includes a fixed joint, an intermediate adjusting joint, and an end-effector joint. The intermediate adjusting joint is a telescopic rod, and the two ends of the telescopic rod are connected to the fixed joint and the end-effector joint respectively through ball joints to achieve multi-dimensional angle adjustment. The end-effector joint is equipped with a 360° rotating dial indicator holder. The dial indicator 4 is installed in the dial indicator holder. By adjusting the universal joint rod support 5, the contact of the dial indicator 4 can be made to vertically contact the base or body of the yarn tube to ensure detection accuracy. The height of the central platform 1 is greater than the height of the inspection station 2, forming an interference-free vertical inspection space to avoid collisions between the yarn tube and the dial indicator 4 or the universal joint rod support 5 when the yarn tube rotates. In this embodiment, the spindle 3 is the same as the spindle of a conventional twisting machine; of course, the upper edge of the spindle 3 can also be provided with annular scale lines to facilitate the operator to observe the rotation angle of the yarn tube, ensure that the yarn tube completes a full inspection after one rotation, and avoid missed inspections.

[0030] In this embodiment, the dial indicator 4 has an accuracy of 0.01 mm, which meets the accuracy requirements for flatness detection; the distance between the center of the four detection stations 2 and the center platform 1 should be such that there is sufficient operating space.

[0031] The working principle of this utility model is as follows: When using, place the yarn tube to be tested in the center of the spindle 3, adjust the leveling bolt to make the horizontal square platform 21 horizontal, adjust the dial indicator 4 to contact the edge of the yarn tube base through the universal indicator rod bracket 5, rotate the spindle 3 to drive the yarn tube to rotate, read the maximum and minimum readings of the dial indicator 4, and calculate the difference. For example, a difference ≤ 10 is judged as qualified, and a difference > 10 is judged as unqualified.

[0032] In summary, this invention uses a spindle disc with parameters consistent with those of a twisting machine as the detection reference surface, fully simulating the actual working conditions of the yarn bobbin. This solves the problem of inaccurate judgment caused by the inconsistency between traditional desktop inspection and the production equipment reference, resulting in more accurate detection results and effectively preventing the misjudgment of qualified yarn bobbins or the entry of unqualified yarn bobbins into production. This invention employs a multi-station (preferably four) design to achieve batch inspection, significantly improving detection efficiency compared to traditional manual single-yarn inspection, meeting the inspection needs of large-scale production. Simultaneously, the dial indicator readings are intuitive, eliminating reliance on operator experience and reducing human error, making it widely applicable to the yarn bobbin quality inspection process in textile enterprises.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
