Description

Technical Field

[0001] The utility model relates to a stretching test device, in particular to a stretching test device for high-elasticity and high-density fabrics, belonging to the technical field of fabrics. Background Art

[0002] Fabric is the material used to make clothes. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly influence the color and shape of clothing. In the world of clothing, clothing fabrics are varied and changing with each passing day, but generally speaking, high-quality and high-end fabrics are mostly comfortable to wear, sweat-wicking and breathable, drape straight, visually noble, and soft to the touch.

[0003] In the processing of high-elastic and high-density fabrics, in order to evaluate the elasticity and recovery ability of the fabrics and ensure that the fabrics have good stretchability and rejection rate, it is necessary to test the tensile strength of the fabrics. Therefore, tensile testing equipment is needed. Authorization announcement number (CN 215767992 U) discloses an elasticity detection mechanism for high-elastic fabric production, including a base plate, a moving component, a fixed component, and a detection component. The moving component is located inside the base plate, and the detection component is installed on the outer wall of the top of the base plate. The moving component includes a moving groove opened on the outer wall of one side of the base plate, a bidirectional screw rotatably installed on the inner wall of the moving groove, and a fixed frame rotatably installed on both ends of the outer wall of the bidirectional screw. A servo motor is installed on the outer wall of one side of the base plate through bolts, and the output shaft of the servo motor is connected to the bidirectional screw through a bearing. A reverse switch is installed on the outer wall of the base plate near the servo motor. In the utility model, the servo motor drives the fixed frame to move, and the tensile performance of the fabric can be detected with higher accuracy. The anti-slip pad prevents the fabric from falling off during the detection process. The fabric begins to sink under the action of the detection block, and the dial displays the numerical value of the fabric sinking. Compared with manual detection, the elasticity of the fabric can be understood more intuitively, and the practicality is stronger;

[0004] However, when testing fabrics, the above technology can only press down on a single part of the fabric and cannot comprehensively evaluate the elasticity and stability of the fabric in all directions. Due to the different structures of the fabrics, there may be differences in the tensile properties in different directions. If multi-directional testing is not possible, the comprehensive mechanical properties of the fabric in actual use cannot be accurately reflected. The test results in a single direction may not be sufficient to ensure that the performance and durability of the product meet the expected standards.

[0005] Therefore, a tensile testing device for high-elastic and high-density fabrics is proposed. Utility Model Content

As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5 As shown, the embodiment of the utility model provides a bottom plate 1, support columns 2 are fixedly installed around the top of the bottom plate 1, a top plate 3 is fixedly installed on the upper end of the support column 2, a baffle 4 is fixedly installed on the inner side of the support column 2, and a stretching mechanism 5 is arranged on the rear side of the baffle 4. The stretching mechanism 5 includes a shell 501, a servo motor 502, a bidirectional screw 503, a threaded sleeve 504, a connecting rod 505, a mounting plate 506, an electric clamp 507 and a through slot 508. A moving mechanism 6 is arranged on the top of the bottom plate 1, and the moving mechanism 6 includes a cylinder 601, The base 602, the electric pressure plate 603, the pressing lever 604 and the guide rail 605, the shell 501 is fixedly installed on the rear side of the baffle 4, the servo motor 502 is fixedly installed on the left side of the shell 501, the bidirectional screw 503 is fixedly installed on the output end of the shell 501, the threaded sleeve 504 is threadedly connected to the left and right sides of the surface of the bidirectional screw 503, the connecting rod 505 is fixedly connected to the front side of the threaded sleeve 504, the mounting plate 506 is fixedly connected to the front end of the connecting rod 505, and the electric clamp 507 is fixedly connected to the front side of the mounting plate 506.

[0030] Through the setting of the stretching mechanism 5, the fabric can be clamped and fixed by the electric clamp 507, and the bidirectional screw 503 is driven to rotate by the servo motor 502, so that the threaded sleeve 504 moves outward along the surface of the bidirectional screw 503, and the fabric is stretched laterally to test the tensile properties of the fabric in a horizontal state. At the same time, the fabric is prevented from sliding during the multi-directional test and affecting the detection structure.

[0031] Example 2

[0032] In one embodiment, the cylinder 601 is fixedly installed on the left side of the top of the base plate 1, the base 602 is arranged on the top of the base plate 1, the output end of the cylinder 601 is fixedly connected to the left side of the surface of the base 602, the electric pressing plate 603 is fixedly connected to the top of the base 602, and the pressing lever 604 is fixedly connected to the rear side of the electric pressing plate 603.

[0033] By setting up the moving mechanism 6, the multi-directional stress conditions that the fabric is subjected to during actual wearing or use can be simulated. Not only can the tensile strength of the fabric in the horizontal state be measured, but also the multi-directional tensile resistance, the maximum force and deformation degree that the fabric can withstand, and the ability of the fabric to restore to its original state can be tested. This is closer to the actual use environment of the fabric, accurately evaluates the anisotropic mechanical properties of the fabric, and ensures that the overall performance of the fabric meets the requirements of specific uses.

[0034] Example 3

[0035] In one embodiment, the guide rail 605 is fixedly connected to the front and rear sides of the top of the bottom plate 1, the bottom of the base 602 is slidably connected to the surface of the guide rail 605, the through slot 508 is opened on the left and right sides of the surface of the baffle 4, and the connecting rod 505 is connected to the mounting plate 506 through the through slot 508. Guide blocks 7 are fixedly installed on the upper and lower sides of the surface of the threaded sleeve 504, and guide grooves 8 are opened on the upper and lower sides of the inner cavity of the shell 501, and the guide blocks 7 are slidably connected to the inner side of the guide groove 8.

[0036] By setting the guide rail 605, the base 602 can be guided during the movement of the base 602 to avoid deviation of the moving direction of the base 602. By setting the guide block 7 and the guide groove 8, the stability of the threaded sleeve 504 during movement can be improved.

[0037] When the utility model is working: after the fabric passes through the bottom of the top of the pressing lever 604 and the two ends are clamped on the inner side of the electric clamp 507, the servo motor 502 can be started to work. When the servo motor 502 is started, the bidirectional screw 503 at the output end will be driven to rotate. When the bidirectional screw 503 is rotating, the threaded sleeve 504 will be driven to move outward through the action of the threaded connection. The movement of the threaded sleeve 504 will drive the connecting rod 505 and the mounting plate 506 to move outward along the through slot 508. While moving, the fabric will be pulled up in the horizontal direction. After maintaining the stretched state, , the electric pressing plate 603 can be started to shrink downward. When the electric pressing plate 603 shrinks, it will drive the pressing lever 604 to move downward, so as to press the top of the fabric, so as to test the longitudinal tensile force of the fabric. At this time, the cylinder 601 is started to work. When the cylinder 601 is started, it will drive the base 602 connected to the output end to move horizontally. When the base 602 moves, it can drive the electric pressing plate 603 and the pressing lever 604 to move horizontally. At this time, the inspection personnel can observe what kind of surface the fabric will produce when it is affected by tensile forces in different directions, so as to detect the tensile performance of the fabric in multiple directions.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
