Description

Technical Field

[0001] This utility model relates to the technical field of fabric pilling performance testing equipment, and in particular to a multi-angle pressure adjustment device for a circular trajectory pilling instrument. Background Technology

[0002] In the process of textile quality inspection, pilling performance is one of the important indicators for evaluating fabric quality. Circular trajectory pilling instrument is a commonly used testing device. It simulates the pilling situation of fabric in actual use by generating relative friction between the sample and the abrasive.

[0003] However, existing circular trajectory pilling instruments have shortcomings in pressure adjustment. On the one hand, pressure adjustment can mostly only be performed in a single direction or at a limited angle, which cannot meet the testing requirements of different fabrics under friction pressure at different angles. On the other hand, existing pressure adjustment devices have complex structures and low adjustment accuracy, making it difficult to guarantee the accuracy and reliability of test results.

[0004] In addition, different types of fabrics have different sensitivities to pressure. Existing instruments are difficult to flexibly adjust the pressure angle and magnitude for diverse fabric types, making the test results unable to truly reflect the pilling and fuzzing performance of the fabric in actual use scenarios.

[0005] Therefore, this utility model proposes a multi-angle pressure adjustment device for a circular trajectory pilling and fuzzing instrument. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and propose a multi-angle pressure adjustment device for a circular trajectory pilling and fuzzing instrument.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a multi-angle pressure adjustment device for a circular trajectory pilling and fuzzing instrument, comprising a mounting assembly, wherein the mounting assembly is composed of a mounting cover and a base frame, the mounting cover being threadedly connected to the base frame, and further comprising:

[0008] The adjusting extrusion assembly consists of an adapter plate, an arc-shaped extrusion seat, and springs. The arc-shaped extrusion seat is located on top of the adapter plate, and the springs are grown between the adapter plate and the base frame. The springs are arranged in a ring, and the included angle between two adjacent springs is equal.

[0009] Furthermore, the bottom of the adapter plate is composed of discs with decreasing diameters from the outside to the inside, and the length of the spring is adapted to the distance between the adapter plate and the base frame.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: The bottom of the adapter plate adopts a disc structure with a decreasing diameter from the outside to the inside, which cooperates with the spring that matches the spacing of the base frame. When subjected to force, the disc structure can guide the adapter plate to tilt at different angles. The spring adapts to the spacing and expands and contracts accordingly. Through elastic deformation, it absorbs and transmits pressure, so that the arc-shaped extrusion seat can maintain stable pressure at multiple angles. This structural design allows the device to achieve flexible and stable adjustment of multi-angle pressure by means of disc guidance and spring elastic adaptation when adjusting the pressure angle, thereby enhancing the adaptability of the device to different testing scenarios.

[0011] Furthermore, a spherical adjustment seat is provided at the bottom of the adapter plate, and a spherical seat is provided on the base frame below the spherical adjustment seat. The base frame and the adapter plate are rotatably connected through the spherical seat and the spherical adjustment seat.

[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: the spherical adjustment seat at the bottom of the adapter plate is rotatably connected to the spherical seat of the base frame to form a universal rotation structure. When it is necessary to adjust the pressure angle, the spherical adjustment seat can rotate freely on the spherical seat, driving the adapter plate and the upper arc-shaped extrusion seat to tilt in multiple directions, so that the pressure direction can be flexibly adjusted to different angles. This spherical rotation design eliminates the angle limitation of traditional rigid connection, allowing the device to easily achieve multi-angle pressure adjustment according to test requirements. Moreover, the rotation process is smooth and stable, ensuring the accuracy and flexibility of pressure application.

[0013] Furthermore, the base frame has an annular limiting groove on the outer side of the adapter plate, and the bottom of the mounting cover has an annular sliding groove, on which an annular limiting frame is rotatably connected.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: the base frame has an annular limiting groove on the outside of the adapter plate, and the annular sliding groove at the bottom of the mounting cover is rotatably connected to the annular limiting frame. When the adapter plate adjusts its angle through the spherical structure, the annular limiting frame slides synchronously in the annular limiting groove, which not only limits the excessive offset of the adapter plate, but also allows the mounting cover and the base frame to rotate relative to each other through the annular sliding groove. This structure that combines limiting and rotation ensures the stability of the adapter plate during multi-angle adjustment, while ensuring the reliable connection of the overall structure of the device, avoiding shaking or dislocation during the adjustment process, and improving the stability and reliability of the device during operation.

[0015] Furthermore, the bottom of the base frame is provided with mounting feet, and there are four mounting feet in total. The four mounting feet are arranged in a ring, and the included angle between any two adjacent mounting feet is equal.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: the four mounting legs at the bottom of the base frame are distributed in a ring at equal angles. This symmetrical structure provides balanced support for the device. During installation, the legs can stably contact the table surface. The ring distribution keeps the center of gravity of the device in the center. When under force, each leg distributes the pressure evenly, avoiding tilting or shaking of the device due to uneven force. This ensures that the entire device remains stable during the multi-angle pressure adjustment process, providing a stable foundation for accurate testing, while enhancing the reliability and applicability of the device installation.

[0017] Furthermore, the bottom of the base frame is provided with a buffer assembly, which consists of a buffer frame and a buffer pad, with two buffer pads respectively disposed at the upper and lower ends of the buffer frame.

[0018] The beneficial effects of adopting the above-mentioned further solution are as follows: The buffer assembly at the bottom of the base frame consists of a buffer frame and buffer pads at the upper and lower ends. During the test, the buffer pads absorb the vibration generated by the operation of the elastic deformation device, while the buffer frame supports the buffer pads and disperses the impact force, preventing the vibration from being transmitted to the base frame and affecting the pressure adjustment accuracy. At the same time, it reduces noise. This structure can reduce the interference of external vibration on the test, enable the device to work in a stable state, extend the service life of the equipment, and improve the stability of the test environment.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, in the adjusting extrusion assembly, the annularly distributed springs connect the adapter plate and the base frame. The top arc-shaped extrusion seat moves with the adapter plate. When pressure is applied, the springs are evenly stressed through the annular symmetrical structure and adaptively expand and contract according to the pressure angle, pushing the arc-shaped extrusion seat to fit the surface of the sample at different angles. With the help of the spring's elastic buffer and uniform support, the arc-shaped extrusion seat maintains stable contact when pressure is applied at multiple angles, realizing flexible pressure transmission and multi-angle adjustment, and improving the uniformity and adaptability of pressure application during testing.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1-5 As shown, this utility model provides a technical solution: a multi-angle pressure adjustment device for a circular trajectory pilling and fuzzing instrument, including a mounting assembly 1, which consists of a mounting cover 11 and a base frame 12. The mounting cover 11 is threadedly connected to the base frame 12, and further includes:

[0032] The adjusting extrusion assembly 2 consists of an adapter plate 21, an arc-shaped extrusion seat 22, and springs 23. The arc-shaped extrusion seat 22 is located on top of the adapter plate 21. The springs 23 are located between the adapter plate 21 and the base frame 12. The springs 23 are arranged in a ring, and the included angle between two adjacent springs 23 is equal. In the adjusting extrusion assembly 2, the ring-shaped springs 23 connect the adapter plate 21 and the base frame 12. The top arc-shaped extrusion seat 22 moves with the adapter plate 21. When pressure is applied, the springs 23 are evenly stressed through the ring symmetrical structure and adapt to the pressure angle, pushing the arc-shaped extrusion seat 22 to conform to the surface of the sample at different angles. With the help of the elastic buffer and uniform support of the springs 23, the arc-shaped extrusion seat 22 maintains stable contact when pressure is applied at multiple angles, realizing flexible pressure transmission and multi-angle adjustment, and improving the uniformity and adaptability of pressure application during testing.

[0033] The bottom of the adapter plate 21 is composed of a disc with a decreasing diameter from the outside to the inside. The length of the spring 23 is adapted to the distance between the adapter plate 21 and the base frame 12. The bottom of the adapter plate 21 adopts a disc structure with a decreasing diameter from the outside to the inside. In cooperation with the spring 23 that is adapted to the distance between the adapter plate 21 and the base frame 12, when subjected to force, the disc structure can guide the adapter plate 21 to tilt at different angles. The spring 23 adapts to the distance and expands and contracts. Through elastic deformation, it absorbs and transmits pressure, so that the arc-shaped extrusion seat 22 can maintain stable pressure at multiple angles. This structural design allows the device to achieve flexible and stable adjustment of pressure at multiple angles by means of the disc guide and the elastic adaptation of the spring 23 when adjusting the pressure angle, thereby enhancing the adaptability of the device to different test scenarios.

[0034] A spherical adjustment seat 211 is provided at the bottom of the adapter plate 21. A spherical seat 14 is provided on the base frame 12 below the spherical adjustment seat 211. The base frame 12 and the adapter plate 21 are rotatably connected to the spherical adjustment seat 211 via the spherical seat 14. The spherical adjustment seat 211 at the bottom of the adapter plate 21 is rotatably connected to the spherical seat 14 of the base frame 12, forming a universal rotation structure. When it is necessary to adjust the pressure angle, the spherical adjustment seat 211 can rotate freely on the spherical seat 14, driving the adapter plate 21 and the upper arc-shaped extrusion seat 22 to tilt in multiple directions, so that the pressure direction can be flexibly adjusted to different angles. This spherical rotation design eliminates the angle limitation of traditional rigid connection, allowing the device to easily achieve multi-angle pressure adjustment according to test requirements. Moreover, the rotation process is smooth and stable, ensuring the accuracy and flexibility of pressure application.

[0035] The base frame 12 has an annular limiting groove 121 on the outer side of the adapter plate 21, and the mounting cover 11 has an annular sliding groove 111 at the bottom. An annular limiting frame 112 is rotatably connected to the annular sliding groove 111. When the adapter plate 21 is adjusted by the spherical structure, the annular limiting frame 112 slides synchronously in the annular limiting groove 121. This not only limits the excessive offset of the adapter plate 21, but also allows the mounting cover 11 and the base frame 12 to rotate relative to each other through the annular sliding groove 111. This structure, which combines limiting and rotation, ensures the stable movement of the adapter plate 21 during multi-angle adjustment, while ensuring the reliable connection of the overall structure of the device, avoiding shaking or dislocation during adjustment, and improving the stability and reliability of the device during operation.

[0036] The base frame 12 has four mounting feet 13 at its bottom, arranged in a ring. The included angle between any two adjacent mounting feet 13 is equal. This symmetrical structure provides balanced support for the device. During installation, the feet can stably contact the platform. The ring arrangement keeps the device's center of gravity in the center, and the pressure is evenly distributed among the feet when under stress, preventing the device from tilting or shaking due to uneven stress. This ensures that the entire device remains stable during multi-angle pressure adjustment of the extrusion assembly 2, providing a stable foundation for accurate testing and enhancing the reliability and applicability of the device installation.

[0037] The bottom of the base frame 12 is composed of a buffer assembly 3, a buffer frame 31, and a buffer pad 32. The two buffer pads 32 are respectively set at the upper and lower ends of the buffer frame 31. The buffer assembly 3 at the bottom of the base frame 12 is composed of the buffer frame 31 and the buffer pads 32 at the upper and lower ends. During the test, the buffer pad 32 absorbs the vibration generated by the operation of the elastic deformation device, while the buffer frame 31 supports the buffer pad 32 and disperses the impact force, preventing the vibration from being transmitted to the base frame 12 and affecting the pressure adjustment accuracy. At the same time, it reduces noise. This structure can reduce the interference of external vibration on the test, enable the device to work in a stable state, extend the service life of the equipment, and improve the stability of the test environment.
