Description

Technical Field

[0001] This utility model relates to the field of fiber drawing equipment technology, and in particular to a concrete anti-cracking fiber drawing equipment. Background Technology

[0002] Crack-resistant fibers, when used in mortar and cement concrete, rely on their unique tensile strength, dispersibility, melting and ignition points, and acid and alkali resistance. They are made from polypropylene as raw material through processes such as melting, extrusion, drawing, and cutting. They can effectively prevent the generation and development of cracks in mortar and cement concrete. To ensure that the crack-resistant fibers can be well dispersed in mortar and cement concrete, the surface of the crack-resistant fibers is treated with a special process before cutting.

[0003] The applicant discovered through a search that a Chinese patent discloses "A Concrete Anti-Crack Fiber Drawing Equipment" with publication (announcement) number "CN211941950U". This patent mainly uses an extrusion plate to extrude the anti-crack fiber raw material, which is then filtered through a filter device and extruded from the die to form a molten film. After cooling in a cooling water tank, it forms anti-crack fiber filaments. However, this device lacks the ability to adjust the tension of the fiber filaments, which may lead to uneven fiber stretching, thus affecting the quality of the fiber. Uneven pressure or temperature fluctuations may also cause fluctuations in fiber quality, thereby affecting the stability and consistency of production. Therefore, we propose a concrete anti-crack fiber drawing equipment. Utility Model Content

[0004] The purpose of this invention is to provide a concrete anti-cracking fiber drawing device to solve the problems mentioned in the background art, such as the lack of fiber tension adjustment, which may lead to uneven fiber stretching and thus affect fiber quality. Uneven pressure or temperature fluctuations may also cause fluctuations in fiber quality, thereby affecting the stability and consistency of production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete crack-resistant fiber drawing device, comprising a base plate, on which a fiber drawing machine, a cooling structure, and a winding structure are respectively installed. An adjustment structure is installed within the cooling structure. The fiber drawing machine is fixedly installed on one side of the top of the base plate. The adjustment structure includes a fixing frame and a mounting frame. The mounting frame slides a slider via a slide rail. A roller is rotatably installed between the sliders via a rotating shaft. A connecting plate is installed on the slider via a slide rod. A screw is threaded onto the fixing frame. The bottom end of the screw is rotatably connected to the connecting plate. The connecting plate is slidably connected to the fixing frame via a guide rod.

[0006] As a preferred embodiment, the cooling structure includes a water tank and fixed blocks. The water tank is fixedly installed on the top of the base plate and is located on one side of the fiber drawing machine. The fixed blocks are fixedly installed around the top of the water tank, and a first guide roller and a second guide roller are rotatably installed between the fixed blocks.

[0007] As a preferred embodiment, the fixing bracket is fixedly installed on the top of the water tank, the mounting brackets are respectively fixedly installed on the inner wall of the water tank, the slide rail is fixedly installed on the inner wall of the mounting bracket, the slider is slidably installed on the slide rail, and the slide rod is fixedly installed on the top of the slider.

[0008] As a preferred embodiment, the slide rod extends through the top wall of the mounting bracket to the top of the mounting bracket, and the slide rod is slidably connected to the top wall of the mounting bracket. The connecting plate is fixedly installed at the top of the slide rod, the guide rod is fixedly installed at the top of the connecting plate, the guide rod extends through the fixing frame to the top of the fixing frame, and the guide rod is slidably connected to the fixing frame.

[0009] As a preferred embodiment, the winding structure includes a support frame, a winding drum, and a first motor. The support frame is fixedly installed on the top of the base plate, the winding drum is rotatably installed between the support frames, the first motor is fixedly installed on the outside of the support frame, and the motor shaft of the first motor is fixedly connected to one end of the winding drum.

[0010] As a preferred embodiment, a drive box is fixedly installed between the support frames, a lead screw is rotatably installed inside the drive box, a second motor is fixedly installed on the outside of the support frame, the motor shaft of the second motor is fixedly connected to one end of the lead screw, a threaded block is threadedly installed on the lead screw, the threaded block is slidably connected to the inner wall of the drive box, and a wire-passing block is fixedly installed at the top of the threaded block.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the set adjustment structure, the screw rotation controls the movement of the roller in the water tank. The fiber filaments from the fiber drawing machine pass through the bottom of the roller via the first guide roller, and then connect to the take-up drum via the second guide roller. The water in the water tank cools the fiber filaments. Water cooling effectively reduces the fiber temperature, reduces the negative impact of temperature on fiber performance, and ensures the mechanical properties and toughness of the fiber. According to different fiber types, the position of the roller in the water tank can be adjusted to adjust the tension of the fiber filaments to adapt to different production needs. It can also coordinate the tension and cooling process, which helps to optimize the immersion time of the fiber in water and make the cooling effect more uniform.

[0013] 2. In the winding structure, the lead screw drives the threading block to move through the threaded block, so that the fiber filaments are evenly wound onto the winding drum. This avoids fiber accumulation, deviation, or unevenness, and prevents the fiber from knotting or irregularly winding during the winding process. The evenly wound fiber filaments can ensure the density and uniformity of the fiber on the winding drum. The high-quality winding effect can improve the quality of the final product, making the surface of the fiber filaments smoother after winding, without looseness or accumulation.

The first guide roller 33 and the second guide roller 34 are opposite to each other.

[0024] The adjustment structure 4 includes a fixed frame 401 and a mounting frame 402. Two fixed frames 401 are fixedly installed on the top of the water tank 31. The mounting frames 402 are respectively fixedly installed on the inner wall of the water tank 31. A slide rail 403 is fixedly installed on the inner wall of the mounting frame 402. A slider 404 is slidably installed on the slide rail 403. A roller 406 is rotatably installed between the sliders 404 via a rotating shaft 405. The rotating shaft 405 and the roller 406 are fixedly connected. A sliding rod 407 is fixedly installed on the top of the slider 404, and the sliding rod 407 passes through the mounting frame. The top wall of the bracket 402 extends above the mounting bracket 402, and the slide rod 407 is slidably connected to the top wall of the mounting bracket 402. The top end of the slide rod 407 is fixedly mounted with a connecting plate 408. The fixing bracket 401 is threadedly mounted with a screw 409. The bottom end of the screw 409 is rotatably connected to the connecting plate 408. The connecting plate 408 is fixedly mounted with guide rods 410 on both sides of the screw 409. The guide rods 410 pass through the fixing bracket 401 and extend to the top end of the fixing bracket 401, and the guide rods 410 are slidably connected to the fixing bracket 401.

[0025] Specifically, by adjusting the screw 409, the position of the roller 406 in the water tank 31 is controlled, the fiber filament is connected to the take-up drum 52, and at the same time, the water in the water tank 31 cools the fiber, effectively reducing the temperature and minimizing the negative impact on the fiber performance. The position of the roller 406 is adjusted according to the fiber type to optimize the tension and cooling process, ensuring that the fiber tension meets production requirements and is cooled evenly, thereby improving the mechanical properties and toughness of the fiber.

[0026] Example 2:

[0027] Please see the appendix Figure 1 and attached Figure 6The winding structure 5 includes a support frame 51, a winding drum 52, and a first motor 53. The support frame 51 is fixedly installed at the top of the base plate 1 and on one side of the cooling structure 3. The winding drum 52 is rotatably installed between the support frames 51. The first motor 53 is fixedly installed on the outside of the support frame 51, and the motor shaft of the first motor 53 is fixedly connected to one end of the winding drum 52. A drive box 54 is fixedly installed between the support frames 51. A lead screw 55 is rotatably installed inside the drive box 54.

[0028] Specifically, the lead screw 55 drives the threading block 58 to move through the threaded block 57, so that the fiber filaments are evenly wound onto the take-up drum 52, avoiding accumulation, deviation or unevenness. Even winding improves the density and uniformity of the fiber, ensuring that the surface of the fiber after winding is flat, without looseness or accumulation, thereby improving the quality of the final product.

[0029] The working principle of this utility model is as follows: This utility model is a concrete crack-resistant fiber drawing device. Water is added to the water tank 31, and the screw 409 is rotated. The screw 409 moves threadedly on the fixed frame 401, thereby driving the connecting plate 408 to move. The connecting plate 408 drives the slider 404 to slide on the mounting frame 402 through the slide rod 407. The slider 404 drives the roller 406 to rise and fall through the rotating shaft 405. The fiber drawn from the fiber drawing machine 2 passes from the top surface of the first guide roller 33 to the bottom of the roller 406, then passes through the top of the second guide roller 34, and finally passes through the threading block 58 and the take-up drum 52 for connection. The first motor 53 and the second motor 56 are started. The motor shaft of motor 53 drives the take-up drum 52 to rotate, and the take-up drum 52 winds up the fiber filaments. During the winding process, the motor shaft of the second motor 56 drives the lead screw 55 to rotate, and the lead screw 55 drives the threaded block 57 to slide in the drive box 54. The threaded block 57 drives the threading block 58 to move. By reversing the second motor 56, the threading block 58 moves in the opposite direction. By moving the threading block 58, the fiber filaments are evenly wound onto the take-up drum 52. When the fiber filaments pass over the roller 406, they will pass through water and be cooled by the water. Depending on the type of fiber filaments, the screw 409 is rotated to adjust the height of the roller 406, thereby adjusting the fiber tension.
