Description

Technical Field

[0001] This utility model relates to the field of fabric testing technology, specifically a fabric multi-directional tensile testing device. Background Technology

[0002] During fabric production and processing, the fabric's flexibility needs to be tested. Therefore, appropriate tensile testing equipment is required. This equipment tests the flexibility by stretching the fabric in different directions, and the fabric's flexibility is adapted for different applications. For example, a fabric tensile testing device with easy fixation (publication number CN217931144U) includes a base and placement platforms mounted on both sides above the base. The base has support legs at both ends, with the two support legs being of equal size and symmetrically arranged about the vertical center line of the base. The device also includes a testing platform mounted above the base, with the length of the testing platform exceeding the length of the base. Placement platforms are connected to the top of both ends of the testing platform. This easy-to-fix fabric tensile testing device is equipped with a bidirectional lead screw, a moving seat, and a bevel gear set. A servo motor drives the bidirectional lead screw to rotate via the bevel gear set, which in turn moves the moving seats at both ends of the bidirectional lead screw left and right, facilitating the tensile testing of the fixed fabric. The stretched length can be clearly observed using scales on both sides of the testing platform. However, this easy-to-fix fabric stretch testing device still has the following drawbacks in actual use:

[0003] Traditional tensile testing devices can only perform unidirectional or bidirectional tensile testing on fabrics. The fabric needs to be removed and repositioned before tensile testing in other directions can be performed. Therefore, the testing efficiency is low and the fabric cannot be stretched in multiple directions at the same time. To address these issues, there is an urgent need for innovative designs based on existing testing devices. Utility Model Content

[0004] The purpose of this invention is to provide a multi-directional stretching detection device for fabrics, in order to solve the problem mentioned in the background art that most traditional stretching detection devices can only stretch fabrics in one or two directions. The fabric needs to be removed and reinstalled in another direction to achieve stretching detection in the other direction. Therefore, the detection efficiency is low and the fabric cannot be stretched in multiple directions at the same time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fabric multi-directional tensile testing device, including a testing platform, an electric motor mounted on the lower end face of the testing platform, and the output shaft of the electric motor connected to a connecting shaft;

[0006] It also includes: a guide mechanism, which is disposed on the outside of the connecting shaft. The guide mechanism is fixedly connected to one end of the connecting rod, and a through groove is provided on the detection platform on the outside of the connecting rod. The other end of the connecting rod is connected to a clamping assembly, which consists of a fixed plate, a movable shaft, a movable plate, and an anti-slip pad.

[0007] Preferably, the guiding mechanism includes a first gear and a second gear fixedly sleeved on the outside of the connecting shaft, and both sides of the first gear are meshed with first racks. When the connecting shaft drives the first gear to rotate, the first gear can drive the two first racks to move in opposite directions through meshing with the first racks.

[0008] Preferably, the second gear is meshed with a second rack on both sides, and the second rack and the first rack are perpendicular to each other. When the second gear rotates, it can also drive the two second racks to move in opposite directions through meshing with the second rack.

[0009] Preferably, the heights of the first gear and the first rack are both lower than the heights of the second gear and the second rack, and the ends of the first rack and the second rack are both fixed with support rods. The bottom of the support rods slides in contact with the inner bottom surface of the testing table. When the racks move, they drive the support rods to slide on the testing table, ensuring stability during movement.

[0010] Preferably, the connecting rod forms a sliding structure through the through groove and the detection table, and the connecting rod and the clamping assembly are both distributed at equal angles on the detection table. When the rack moves, it drives the connecting rod to slide in the through groove, which in turn drives the clamping assembly to move synchronously.

[0011] Preferably, one end of the fixed plate and the connecting rod are fixedly connected, and the other end of the connecting rod is fixed on the first rack and the second rack. A movable shaft is fixed at the edge of the fixed plate, and the movable plate can rotate on the fixed plate through the movable shaft.

[0012] Preferably, the movable plate is rotatably sleeved on the upper end of the movable shaft, and the lower surface of the movable plate is an inclined surface. An anti-slip pad is attached to the inclined surface of the movable plate, and the movable plate can clamp the fabric between the fixed plate through its inclined surface.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the multi-directional tensile testing device for fabric can simultaneously clamp different positions of the fabric during testing, thus enabling multi-directional tensile testing of the fabric with the same device without removing the fabric and changing its installation position, thereby improving testing efficiency. The specific details are as follows:

[0014] 1. When the movable plate is rotated, its inclined surface can contact the fabric, thereby clamping the fabric between the fixed plate and the movable plate. The anti-slip pad contacts the fabric to improve the stability of the clamping. Since there are multiple clamping components, multiple edges of the fabric can be clamped at the same time.

[0015] 2. Through the meshing transmission of the first gear and the two first racks, and the meshing transmission of the second gear and the two second racks, the four racks can move in opposite directions respectively. Since the first rack and the second rack are perpendicular to each other, they can drive the clamping components that are distributed at equal angles to move away from each other when moving, so that the four edges of the fabric can be stretched at the same time for detection.

[0023] 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.

[0024] Please see Figures 1-6 This utility model provides a technical solution:

[0025] To address the problems existing in the prior art, this embodiment provides the following technical solution: a fabric multi-directional stretching detection device, comprising a detection platform 1, a motor 2 mounted on the lower end face of the detection platform 1, and the output shaft of the motor 2 connected to a connecting shaft 3; further comprising: a guide mechanism disposed on the outside of the connecting shaft 3, the guide mechanism being fixedly connected to one end of a connecting rod 9, and a through groove 10 being provided on the detection platform 1 on the outside of the connecting rod 9, the other end of the connecting rod 9 being connected to a clamping assembly 11, and the clamping assembly 11 being composed of a fixed plate 12, a movable shaft 13, a movable plate 14, and an anti-slip pad 15.

[0026] Most existing tensile testing devices can only perform unidirectional or bidirectional tensile testing on fabrics. The fabric needs to be removed and repositioned to perform tensile testing in the other direction, resulting in low testing efficiency and the inability to simultaneously perform multi-directional tensile testing. The guiding mechanism includes a first gear 4 and a second gear 6 fixedly sleeved on the outside of the connecting shaft 3. Both sides of the first gear 4 are meshed with a first rack 5; both sides of the second gear 6 are meshed with a second rack 7, and the second rack 7 and the first rack 5 are perpendicular to each other. The heights of the first gear 4 and the first rack 5 are both lower than... The height of the second gear 6 and the second rack 7 are determined, and the ends of the first rack 5 and the second rack 7 are both fixed with support rods 8, and the bottom of the support rods 8 slides in contact with the inner bottom surface of the testing table 1; the connecting rod 9 forms a sliding structure with the testing table 1 through the through groove 10, and the connecting rod 9 and the clamping assembly 11 are distributed at equal angles on the testing table 1; the fixed plate 12 is fixedly connected to one end of the connecting rod 9, and the other end of the connecting rod 9 is fixed to the first rack 5 and the second rack 7, and a movable shaft 13 is fixed at the edge of the fixed plate 12; the movable plate 14 is rotatably sleeved on the movable... The upper end of shaft 13 and the lower surface of movable plate 14 are inclined surfaces, and anti-slip pads 15 are attached to the inclined surfaces of movable plate 14. First, the fabric to be stretched is placed inside the clamping assembly 11, so that the edge of the fabric is on the fixed plate 12. Then, the movable plate 14 is rotated so that its inclined surface contacts the fabric. The edge of the fabric is clamped by the fixed plate 12 and the movable plate 14. The anti-slip pads 15 improve the stability of the clamping. After clamping is completed, the motor 2 runs and drives the first gear 4 and the second gear 6 to rotate synchronously through the connecting shaft 3. When the first gear 4 rotates, it drives the two first racks 5 to move in opposite directions. Similarly, when the second gear 6 rotates, it drives the two second racks 7 to move in opposite directions. The racks maintain stability by sliding on the inner bottom surface of the detection table 1 through the support rod 8. The racks can also drive the connecting rod 9 to slide in the through groove 10. Since the first racks 5 and the second racks 7 are perpendicular to each other, they can drive the clamping components 11, which are distributed at equal angles, to move away from each other. This allows the four edges of the fabric to be stretched simultaneously for detection, improving the convenience of the detection.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
