Description

Technical Field

[0001] This utility model relates to the field of fiber processing equipment technology, specifically a functional fiber stretching device. Background Technology

[0002] Functional fibers, such as high-performance polyethylene and carbon fiber, possess special properties (e.g., antibacterial, abrasion-resistant, high elasticity), and are widely used in textiles, medical, and aerospace fields.

[0003] Existing stretching devices mostly use a fixed roller spacing structure when stretching fibers. Although this design is simple and low in cost, it cannot adjust the stretching tension in real time according to the fiber material and specifications, which can easily lead to fiber breakage or insufficient stretching, affecting the product qualification rate and restricting the efficiency of functional fiber production and the stability of product quality.

[0006] Furthermore, a cross plate is fixedly connected to both ends of the rotating tube, the first motor is fixedly connected to the side wall of a cross plate, the threaded tube is rotatably connected between the cross plates, an opening groove is opened on the side wall of the rotating tube, and a protruding plate is fixedly connected to the side wall of the threaded tube, the protruding plate sliding in the opening groove.

[0007] Furthermore, a second connecting plate is fixedly connected to the top of the convex plate, a first connecting plate is fixedly connected to the arc plate, the two ends of the connecting rod are respectively rotatably connected to the side wall of the second connecting plate and the side wall of the first connecting plate, a sliding plate is fixedly connected to the end of the arc plate, and a long groove is opened on the surface of the long plate, and the sliding plate slides in the long groove.

[0008] Furthermore, it also includes a heating mechanism, which includes a fixed frame, a slide rail, a second lead screw, a threaded plate, a lifting plate, and a heating arc plate; The fixed frame is fixedly connected to the top surface of the base plate. There are two slide rails, which are fixedly connected to both sides of the fixed frame. There are two second lead screws, which are rotatably connected to the two slide rails. There are four threaded plates, which are threadedly connected to the two ends of the two second lead screws and slide within the two slide rails.

This reduces the tension on the take-up roller as it rotates the four arc plates through the fiber. The tensile tension is adjusted in real time according to the fiber material and specifications to ensure sufficient fiber stretching and improve the product qualification rate.

[0015] 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.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figures 1-4As shown, this utility model is a functional fiber stretching device, comprising: The base plate 100 has a central plate 110 fixedly connected to the top center of the base plate 100, and side plates 120 fixedly connected to both ends of the top of the base plate 100. Tension adjustment mechanism 200 includes a rotating tube 210, a long plate 220, an arc plate 230, a first motor 240, a first lead screw 250, a threaded tube 260, and a connecting rod 270. Rotating tube 210 is rotatably connected between the central plates 110. Multiple long plates 220 are fixedly connected to the side walls at both ends of rotating tube 210. Multiple arc plates 230 are slidably connected to the side walls of long plates 220 at both ends. A first motor 240 is fixedly connected to one end inside rotating tube 210. A first lead screw 250 is rotatably connected to rotating tube 210 and its end is fixedly connected to the power output end of the first motor 240. Threaded tube 260 is threadedly connected to the first lead screw 250. Multiple connecting rods 270 are rotatably connected to the side walls of threaded tube 260 and the bottom of arc plates 230 at both ends. When the first motor 240 is started, it drives the first lead screw 250 to rotate. The rotation of the first lead screw 250 drives the threaded tube 260 to slide. The threaded tube 260 drives one end of connecting rod 270 to move, so that the other end of connecting rod 270 drives the arc plates 230 to descend on long plates 220, thereby reducing the diameter formed by the four arc plates 230. A third motor 410 is fixedly connected to the side wall of one side plate 120, and a take-up roller 420 is rotatably connected between the side plates 120 at one end. One end of the take-up roller 420 is fixedly connected to the power output end of the third motor 410, and an unwind roller 430 is rotatably connected between the side plates 120 at the other end. After the fiber is wrapped around the unwind roller 430, the fiber is pulled out, passes around the four arc plates 230, and then wraps around the take-up roller 420. The take-up roller 420 is rotated by the third motor 410 to pull the fiber. Because the diameter of the four arc plates 230 is larger than that of the take-up roller 420, the fiber is stretched when it pulls the four arc plates 230 to rotate. A cross plate 211 is fixedly connected to both ends of the rotating tube 210. The first motor 240 is fixedly connected to the side wall of a cross plate 211. The threaded tube 260 is rotatably connected between the cross plates 211. An opening slot 212 is opened on the side wall of the rotating tube 210. A protruding plate 261 is fixedly connected to the side wall of the threaded tube 260. The protruding plate 261 slides in the opening slot 212. The cross plate 211 facilitates the fixing of the first motor 240. The sliding of the protruding plate 261 in the slot 211 restricts the threaded tube 260 from rotating with the first lead screw 250, so that the first lead screw 250 can only slide. The top of the convex plate 261 is fixedly connected to the second connecting plate 262, the arc plate 230 is fixedly connected to the first connecting plate 231, the two ends of the connecting rod 270 are respectively rotatably connected to the side wall of the second connecting plate 262 and the side wall of the first connecting plate 231, the end of the arc plate 230 is fixedly connected to the sliding plate 232, the surface of the long plate 220 is provided with a long groove 221, the sliding plate 232 slides in the long groove 221, the sliding plate 232 slides in the long groove 221 to stabilize the arc plate 230, the sliding of the threaded tube 260 drives the convex plate 261 to slide, the convex plate 261 drives one end of the connecting rod 270 to rotate and move at the same time, so that the other end of the connecting rod 270 drives the first connecting plate 231 to descend while the first connecting plate 231 rotates, the descent of the first connecting plate 231 drives the arc plate 230 to descend, changing the diameter of the four arc plates 230; Working principle: After the fiber is wound onto the unwinding roller 430, it is pulled out, passes around the four arc plates 230, and then winds onto the take-up roller 420. The third motor 410 drives the take-up roller 420 to rotate, pulling the fiber. Because the diameter of the four arc plates 230 is larger than that of the take-up roller 420, the fiber is stretched as it pulls the four arc plates 230 to rotate. The first motor 240 is started, driving the first lead screw 250 to rotate. The rotation of the first lead screw 250 causes the protruding plate 261 on the side wall of the threaded tube 260 to slide in the opening groove 212. The protruding plate 261 drives one end of the connecting rod 270 to rotate and move simultaneously, making... The other end of the connecting rod 270 drives the first connecting plate 231 to descend while the first connecting plate 231 rotates. The descent of the first connecting plate 231 drives the arc plate 230 to descend, causing the slide plate 232 at the end of the arc plate 230 to slide down the long groove 221, thereby reducing the diameter of the four arc plates 230. This reduces the tension of the take-up roller 420 as it drives the four arc plates 230 to rotate through the fiber. Similarly, after reducing the tension, the first motor 240 is started to drive the first lead screw 250 to reverse, causing the arc plate 230 to slide up and increase the tension. The tensile tension is adjusted in real time according to the fiber material and specifications to ensure that the fiber is fully stretched and improve the product qualification rate.

[0018] Please see Figures 1-4 As shown, this embodiment, based on the above embodiment, further includes: The heating mechanism includes a fixed frame 310, a slide rail 320, a second lead screw 330, a threaded plate 340, a lifting plate 350, and a heating arc plate 360.

Two second lead screws 330 are rotatably connected to the two slide rails 320. Four threaded plates 340 are threadedly connected to the two ends of the two second lead screws 330 and slide within the two slide rails 320. Two lifting plates 350 are fixedly connected to the side walls of the threaded plates 340 at both ends. Two heating arc plates 360 are fixedly connected to the surfaces of the two lifting plates 350. When the two second lead screws 330 are rotated, the threads at both ends of the second lead screws 330 are opposite, causing the two lead screws 330 to rotate and drive the two threaded plates 340 to slide closer. The two threaded plates 340 drive the two lifting plates 350 to slide closer, so that the two heating arc plates 360 wrap around the fiber and start the heating arc plates 360 to heat the fiber, so that the fiber is heated evenly and is easy to stretch. A second motor 371 is fixedly connected to the bottom of a fixed frame 310. The end of a second lead screw 330 is fixedly connected to the power output end of the second motor 371. A driving wheel 372 is fixedly connected to the top of a second lead screw 330. A driven wheel 374 is fixedly connected to the top of another second lead screw 330. A transmission belt 373 is fitted onto the driving wheel 372 and the driving wheel 372. When the second motor 371 is started, it drives one second lead screw 330 to rotate. The second lead screw 330 drives the driving wheel 372 to rotate. The driving wheel 372 drives the driven wheel 374 to rotate through the transmission belt 373. The driven wheel 374 drives the other second lead screw 330 to rotate, so that the two second lead screws 330 rotate simultaneously. The side wall of the fixed frame 310 has a side groove 311. The side wall of the threaded plate 340 is fixedly connected to the connecting column 341. The side wall of the connecting column 341 is fixedly connected to the side wall of the lifting plate 350. The connecting column 341 slides in the side groove 311. The sliding of the threaded plate 340 drives the connecting column 341 to slide in the side groove 311. The connecting column 341 drives the lifting plate 350 to slide, so that both ends of the lifting plate 350 slide with the threaded plate 340. Working principle: The second motor 371 is started to drive one second lead screw 330 to rotate. The second lead screw 330 drives the driving wheel 372 to rotate. The driving wheel 372 drives the driven wheel 374 to rotate through the transmission belt 373. The driven wheel 374 drives the other second lead screw 330 to rotate, so that the two second lead screws 330 rotate simultaneously. The rotation of the second lead screws 330 drives the two threaded plates 340 to slide closer. The two threaded plates 340 drive the two connecting columns 341 to slide closer within the cross plate 211. The two connecting columns 341 drive the two lifting plates 350 to slide closer, so that the two heating arc plates 360 wrap around the fiber and start the heating arc plates 360 to heat the fiber, so that the fiber is evenly heated to the optimal temperature for stretching, avoiding uneven heating that could cause the fiber to stretch and break.
