Technical Field

[0001] This utility model relates to the field of fabric testing technology, and in particular to a fabric stretchability testing device. Background Technology

[0002] Fabrics refer to various textile materials used to make clothing, home furnishings, decorations, etc. Fabrics can be made from natural fibers or synthetic fibers. During the fabric production process, various tests are required to ensure the fabric meets the required standards. One such test is the fabric's stretchability. When conducting stretchability tests, a relatively large tensile force is typically used. Simply clamping the fabric can cause it to shift or even detach during testing, interrupting the test and affecting the testing schedule. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a fabric stretchability testing device to solve the problem that the fabric is easily displaced or even falls off during the test when the fabric is fixed by clamping, causing the test to be interrupted.

[0004] To achieve the above objectives, this utility model provides a fabric stretchability testing device, including a base plate, an L-shaped fixing frame fixedly connected to the top of the base plate, and an L-shaped movable frame slidably mounted on the top of the base plate, and further comprising:

[0005] Two rolling clamping mechanisms are respectively installed on the top of the fixed frame and the movable frame, and are used to clamp and wrap the fabric to be tested. The rolling clamping mechanism includes a support member rotatably installed on the fixed frame and the movable frame, a clamping member installed on the top of the support member for clamping and wrapping the fabric, and a locking member installed on the support member for fixing the fabric after the clamping member wraps it.

[0006] The pressing unit, located on the side away from the fixed frame and the movable frame, is used to press the fabric wrapped around the clamp.

[0007] Preferably, the support includes a mounting column rotatably mounted on a fixed frame and a movable frame, with a support base fixedly connected to the top of the mounting column.

[0008] Preferably, the clamping member includes a clamping plate one fixedly disposed on the top of the support base and a clamping plate two sliding on the top of the support base. The cross-section of the clamping plate one and the clamping plate two is semi-circular. A groove is provided at the top of the support base. A sliding rod is fixedly connected to the inner wall of the groove. A sliding seat that slides on the sliding rod is fixedly connected to the bottom end of the clamping plate two. A spring is sleeved on the sliding rod and fixedly connected to the side wall of the sliding seat and the inner wall of the groove.

[0009] Preferably, the locking component includes a rotating plate fixedly sleeved on the mounting column, and locking grooves are symmetrically provided on both the fixed frame and the movable frame. The rotating plate is provided with symmetrically arranged fixed columns, and one end of the fixed column extends into the interior of the locking groove and is threadedly connected to the locking groove.

[0010] Preferably, the pressing unit includes an electric push rod fixedly disposed on the side wall of the fixing frame, and the output shaft of the electric push rod is fixedly connected to a pressing plate for pressing the wound fabric.

[0011] Preferably, the top of the base plate is provided with a moving unit for adjusting the position of the moving frame. The moving unit includes a moving groove opened at the top of the base plate, a moving seat fixedly connected to the bottom end of the moving frame and sliding on the inner wall of the moving groove, a motor fixedly connected to the inner wall of the moving groove, and a lead screw connected to the motor output shaft through the moving seat and threadedly connected to the moving seat.

[0012] Preferably, the top of the base plate is fixedly connected to a baffle located between the fixed frame and the movable frame for stopping one side of the movable frame.

[0013] The beneficial effects of this utility model are as follows: By setting a base plate, a fixed frame, a movable frame, and a clamping component, it is easy to clamp the fabric. Then, rotating the support component drives the clamping component to wrap the fabric. With the help of the locking component, the support component is locked, which improves the stability of the fabric wrapping. In addition, the pressing unit presses the fabric wrapped on the clamping component, which further improves the tightness of the fabric clamping. Then, by moving the movable frame, the clamping component is driven to unfold the fabric to realize the fabric stretchability test, which effectively reduces the probability of the fabric falling off, thereby improving the stability of the fabric stretchability test.

[0022] This specification provides one or more embodiments of a fabric stretchability testing device, such as... Figure 1 , Figure 2 and Figure 3 As shown, the system includes a base plate 1, an L-shaped fixed frame 2 fixed to the top of the base plate 1, and an L-shaped movable frame 3 slidably mounted on the top of the base plate 1. It also includes:

[0023] Two rolling clamping mechanisms are respectively installed on the top of the fixed frame 2 and the movable frame 3, and are used to clamp and wrap the fabric to be tested. The rolling clamping mechanism includes a support member rotatably installed on the fixed frame 2 and the movable frame 3, a clamping member installed on the top of the support member for clamping and wrapping the fabric, and a locking member installed on the support member for fixing the fabric after the clamping member wraps it.

[0024] The pressing unit is located on the side away from the fixed frame 2 and the movable frame 3 and is used to press the fabric wrapped on the clamp.

[0025] In use, the fabric is clamped by adjusting the clamping parts, and then the support is rotated to drive the clamping parts to wrap around the fabric. The locking parts lock the support, which improves the stability of the fabric wrapping. The pressing unit presses the fabric wrapped around the clamping parts, which further improves the tightness of the clamping. Then, the moving frame 3 drives the clamping parts to unfold the fabric, which effectively reduces the probability of the fabric falling off, thereby improving the stability of the fabric stretchability test.

[0026] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the support includes a mounting column 6 rotatably mounted on the fixed frame 2 and the movable frame 3, with a support base 7 fixedly connected to the top of the mounting column 6. This design, through the mounting column 6 and the support base 7, effectively supports the clamping component and facilitates the wrapping of the fabric by the clamping component.

[0027] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the clamping member includes a clamping plate 8 fixedly disposed at the top of the support base 7 and a clamping plate 9 sliding at the top of the support base 7. The cross-section of the clamping plate 8 and the clamping plate 9 is semi-circular. The top of the support base 7 is provided with a groove 10. A slide rod 11 is fixedly connected to the inner wall of the groove 10. A slide seat 12 sliding on the slide rod 11 is fixedly connected to the bottom end of the clamping plate 9. A spring 13 is sleeved on the slide rod 11 and fixedly connected to the side wall of the slide seat 12 and the inner wall of the groove 10. With this design, when the operator pulls clamp 29 to slide it on the top of support base 7, clamp 29 will cause slide base 12 to slide on slide rod 11, and spring 13 will be compressed, thus opening clamp 29 from clamp 18. Then, the fabric to be tested is placed between clamp 18 and clamp 29, and clamp 29 is released. Under the force of spring 13, clamp 29 will move closer to clamp 18, thus clamping the fabric between clamp 18 and clamp 29, which facilitates the wrapping of the fabric. Then, rotating support base 7 will cause support base 7 to drive clamp 18 and clamp 29 to rotate synchronously, which makes it easier for the fabric to be wrapped around clamp 18 and clamp 29 multiple times, which can improve the clamping stability of the fabric.

[0028] In embodiments of this utility model, such as Figure 2 and Figure 3As shown, the locking component includes a rotating plate 14 fixedly sleeved on the mounting post 6. Both the fixed frame 2 and the movable frame 3 have symmetrically arranged locking grooves 16. A symmetrically arranged fixing post 15 passes through the rotating plate 14, with one end of the fixing post 15 extending into the interior of the locking groove 16 and threadedly connected to it. This design allows for secure fixing of the support base 7 after the fabric is wrapped around the outer walls of the clamping plates 8 and 9, and the fixing post 15 is moved directly above the locking groove 16. The fixing post 15 is then inserted into the locking groove 16 and rotated, achieving a threaded connection between the fixing post 15 and the locking groove 16. This effectively secures the fabric after wrapping, improving the stability of the fabric clamping.

[0029] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the pressing unit includes an electric push rod 4 fixedly mounted on the side wall of the fixing frame 2. The output shaft of the electric push rod 4 is fixedly connected to a pressing plate 5 for pressing the wound fabric. With this design, after the fabric is fixed, activating the electric push rod 4 will drive the pressing plate 5 to move, facilitating the pressing plate 5 to press the fabric and further clamping the fabric, providing stability for the fabric stretchability test.

[0030] In embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the top of the base plate 1 is provided with a moving unit for adjusting the position of the moving frame 3. The moving unit includes a moving groove 17 formed at the top of the base plate 1. The bottom end of the moving frame 3 is fixedly connected to a moving seat 20 that slides on the inner wall of the moving groove 17. A motor 18 is fixedly connected to the inner wall of the moving groove 17. The output shaft of the motor 18 is connected to a lead screw 19 that passes through the moving seat 20 and is threadedly connected to the moving seat 20. With this design, by starting the motor 18, the motor 18 drives the lead screw 19 to rotate. Through the threaded connection between the lead screw 19 and the moving seat 20, and the sliding action between the moving seat 20 and the moving groove 17, the moving seat 20 will drive the moving frame 3 to move. In turn, the moving frame 3 will cause the fabric to stretch, effectively providing convenience for fabric stretchability testing.

[0031] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, a baffle 21 is fixedly connected to the top of the base plate 1, located between the fixed frame 2 and the movable frame 3, to stop one side of the movable frame 3. This design, through the design of the baffle 21, allows for the limitation of the movable frame 3.
