[0002] Chemical fiber fabrics are a new type of clothing developed in modern times. There are many types, mainly referring to pure, blended or interwoven fabrics made from chemical fibers. In other words, fabrics woven from pure chemical fibers do not include blends or interwoven fabrics with natural fibers.

After wrapping, the user rotates the locking bolt, which drives the movable friction plate to move. The movable friction plate is in close contact with the fixed friction plate, so that the rotating disk cannot rotate, thus preventing the rotating disk from rotating and affecting the clamping effect.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1 and Figure 2 As shown, this embodiment provides a device for testing the toughness of chemical fibers, including a base 100. Movable frames 200 are movably mounted on both sides of the upper end of the base 100. A clamping structure is provided at the upper end of the movable frame 200, and a connecting seat 210 is fixedly mounted at the lower end of the movable frame 200. A traction wire 320 is movably inserted inside the connecting seat 210, and a limiting structure is provided between the traction wire 320 and the connecting seat 210. A fixed seat 300 is fixedly mounted in the middle of the upper end of the base 100, and a tension sensor 310 is fixedly mounted in the middle of the fixed seat 300. One end of the traction wire 320 is connected to the tension sensor 310. The base 100 is connected to the slide rail 101 on both sides of the upper end. The middle of both sides of the upper end of the base 100 is provided with a moving groove 102. The moving frame 200 is slidably connected to the slide rail 101. A double-threaded screw 110 is rotatably installed inside the base 100. The two ends of the double-threaded screw 110 are movably fitted with moving thread sleeves 111. A moving block 112 is provided on one side of the moving thread sleeve 111. The upper end of the moving block 112 passes through the moving groove 102 and is connected to the moving frame 200. A drive motor 120 is fixedly installed on one side of the base 100. The output end of the drive motor 120 is connected to the double-threaded screw 110 for transmission.

[0029] In this embodiment, the two ends of the fiber fabric are fixed to two movable frames 200 by a clamping structure. The traction rope is connected to the connecting seat 210 of the movable frame 200 through a limiting structure. The drive motor 120 drives the double-threaded screw 110 to rotate. The movable screw sleeve 111 moves along the double-threaded screw 110 in the opposite direction under the action of the thread. The movable screw sleeve 111 drives the movable frame 200 to move to both sides through the movable block 112 to pull the fiber fabric. The tension sensor 310 is measured through the traction line 320, which facilitates the detection of the toughness of the fiber fabric.

[0030] like Figure 2 and Figure 3 As shown, this embodiment provides a toughness testing device for chemical fibers. The limiting structure includes a mounting groove 211, which is opened inside the connecting seat 210. A groove 321 is opened on the surface of the traction wire 320. A locking rack 322 is provided inside the groove 321. A locking block 213 is movably inserted into the lower end of the mounting groove 211. The lower end of the locking block 213 is movably inserted into the groove 321 and engages with the locking rack 322. The width of the locking block 213 is equal to the width of the mounting groove 211 and the groove 321. A clamping bolt 212 is movably inserted into the upper end of the connecting seat 210. The lower end of the clamping bolt 212 is rotatably connected to the locking block 213.

[0031] In this embodiment, the user rotates the clamping bolt 212, which causes the locking tooth block 213 to move downward. The width of the locking tooth block 213 is equal to that of the mounting groove 211 and the recess 321, so that the locking tooth block 213 cannot rotate. The locking tooth block 213 moves downward as the clamping bolt 212 rotates, and the locking tooth block 213 engages with the locking rack 322, so that the traction line 320 can be fixedly connected to the connecting seat 210, thereby facilitating connection with the tension sensor 310.

[0032] like Figure 4 and Figure 5As shown, this embodiment provides a toughness testing device for chemical fibers. The clamping structure includes a rotating disk 220, which is rotatably mounted on the upper ends of both sides inside the movable frame 200. A fixing clamping bar 221 is fixedly installed between the two rotating disks 220. Clamping sleeves 224 are rotatably installed on both sides of the lower end of the fixing clamping bar 221. The two clamping sleeves 224 are connected to each other through a transmission sprocket and a transmission chain. A clamping screw 225 is movably inserted inside the clamping sleeve 224. A movable clamping bar 222 is fixedly installed on the upper end of the clamping screw 225. Clamping teeth 223 are provided on the opposite side of the movable clamping bar 222 and the fixing clamping bar 221. One of the rotating disks 220... A rotating block 226 is fixedly installed on one side, and a fixed friction plate 230 is provided on the surface of another rotating disk 220. A movable groove is opened on one side of the inner wall of the movable frame 200. A movable friction plate 231 is movably installed inside the movable groove. The movable friction plate 231 is in contact with the fixed friction plate 230. A pressure rod 232 is fixedly installed on one side of the movable friction plate 231. One end of the pressure rod 232 is movably inserted through the outside of the movable frame 200 and is equipped with a connecting ring 235. A compression spring 233 connected to the movable friction plate 231 is sleeved on the surface of the pressure rod 232. A locking bolt 234 is movably inserted through one side of the movable frame 200. One end of the locking bolt 234 is rotatably connected to the movable friction plate 231.

[0033] In this embodiment, the user inserts one end of the fiber fabric between the fixed clamping strip 221 and the movable clamping strip 222. The user rotates the clamping screw sleeve 224, and the two clamping screw sleeves 224 rotate synchronously under the action of the transmission sprocket and the transmission chain. The clamping screw 225 drives the movable clamping strip 222 to move to one side of the fixed clamping strip 221, so that the fiber fabric is fixedly clamped between the fixed clamping strip 221 and the movable clamping strip 222, which facilitates the quick fixation of the fiber fabric. The user rotates the rotating disk 220 by rotating the rotating block 226. The rotating disk 220 rotates synchronously under the action of the fixed clamping strip 221, which can wrap the clamped fiber fabric, thereby enhancing the clamping effect. After wrapping, the user rotates the locking bolt 234, which drives the movable friction plate 231 to move. The movable friction plate 231 is in close contact with the fixed friction plate 230, so that the rotating disk 220 cannot rotate, thus preventing the rotating disk 220 from rotating and affecting the clamping effect.
