Description

Technical Field

[0001] This utility model relates to the technical field of artificial grass fiber production equipment, and in particular to an artificial grass fiber stretching device. Background Technology

[0002] Artificial grass fibers are typically produced using synthetic fiber materials (such as polypropylene and polyester). Stretching equipment is used to change the shape and properties of the grass fibers through a mechanical stretching process, so that they can achieve the desired strength, elasticity and appearance. This process plays a key role in the spinning and post-processing stages, and therefore involves technologies from multiple fields such as textiles, material processing and mechanical design.

[0003] The applicant discovered through a search that a Chinese patent discloses "An Artificial Grass Fiber Stretching Device" with publication (announcement) number "CN216068658U". This patent mainly uses a rotating roller to stretch artificial grass fibers, and a first heating wire can heat the rotating roller. The artificial grass fibers can deform more easily after being heated. This application can improve the stretching quality of artificial grass fibers as much as possible. However, different batches of grass fibers may have different stretching requirements. Without an adjusting roller to flexibly adjust, it may be impossible to adjust the stretching process according to the characteristics of the grass fibers during production, reducing production adaptability. The deformation of the grass fibers cannot be controlled, which may lead to uneven stretching of the grass fibers, affecting the stretching effect and the quality of the final product. Therefore, we propose an artificial grass fiber stretching device. Utility Model Content

[0004] The purpose of this invention is to provide an artificial grass fiber stretching device to solve the problems mentioned in the background art, which are that different batches of grass fibers may have different stretching requirements. Without an adjusting roller to flexibly adjust, it may be impossible to adjust the stretching process according to the characteristics of the grass fibers during production, which reduces production adaptability. The deformation of the grass fibers cannot be controlled, which may lead to uneven stretching of the grass fibers, affecting the stretching effect and the quality of the final product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an artificial grass fiber stretching device, comprising a housing, on which a transmission structure, an adjustment structure, and a heating structure are respectively installed. The adjustment structure includes a fixed frame, a lead screw, a threaded block, a second motor, a slide, a slide rod, a slider, and an adjusting roller. The fixed frame is equipped with the threaded block via the second motor and the lead screw. The slide is slidably equipped with the slider via the slide rod. The adjusting roller is rotatably installed between the threaded block and the slider. A sliding groove is provided on the side of the housing, and the adjusting roller is slidably connected to the sliding groove.

[0006] As a preferred embodiment, the transmission structure includes a first roller shaft, a second roller shaft, a third roller shaft, a first motor, and a chain belt. The first roller shaft, the second roller shaft, and the third roller shaft are rotatably installed inside the housing. A sprocket is fixedly installed at one end of each of the first roller shaft, the second roller shaft, and the third roller shaft. The sprockets are connected by the chain belt. The first motor is fixedly installed on the side of the housing away from the sprockets. The motor shaft of the first motor is fixedly connected to one end of the first roller shaft.

[0007] As a preferred embodiment, the heating structure includes a heating box, a heating wire, a motor frame, and a third motor. The heating box is fixedly installed on the top of the box body, and an air slot is provided on the top of the heating box. The third motor is fixedly installed inside the heating box through the motor frame, and its motor shaft is fixedly connected to a fan blade. The heating wire is fixedly installed inside the heating box and located below the fan blade.

[0008] As a preferred embodiment, detachable sealing plates are installed at both ends of the housing, and handles are fixedly installed on the sealing plates.

[0009] As a preferred embodiment, the fixing frame is fixedly installed on the side of the housing, the lead screw is rotatably installed inside the fixing frame, the threaded block is threadedly installed on the lead screw and slidably connected to the inner wall of the fixing frame, and the second motor is fixedly installed on the top of the fixing frame, with its motor shaft fixedly connected to the top of the lead screw.

[0010] As a preferred embodiment, the slide is fixedly installed on the other side of the housing, the slide rod is fixedly installed inside the slide, and the slider is slidably installed on the slide rod.

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

[0012] 1. Through the set adjustment structure, the lead screw controls the movement of the threaded block, thereby driving the adjustment roller to move. The threaded connection between the lead screw and the threaded block makes the movement of the adjustment roller more precise. It can finely adjust the force applied to the grass fibers during the stretching process, ensuring that the artificial grass fibers are stretched more evenly and avoiding over- or under-stretching. The movement of the adjustment roller is also very smooth, reducing mechanical vibration and unnecessary impact, which helps to improve the stretching quality of artificial grass fibers, reduce grass fiber damage, reduce manual intervention, improve the level of production automation, and reduce the impact of human factors on production quality.

[0013] 2. The heating structure features heating wires that draw in external air into the heating chamber via fan blades. This heated air then heats the grass fibers, ensuring even distribution throughout the chamber. This guarantees uniform temperature distribution during the stretching process, preventing localized overheating or underheating and improving the stability and quality of the stretching. By controlling the fan blade speed and the power of the heating wires, the temperature within the chamber can be controlled, allowing for more flexible temperature adjustment. Real-time adjustments can be made based on different stretching states and requirements of the grass fibers, enhancing the adaptability of the production process. Attached Figure Description

The first motor 24 is fixedly installed on the side of the housing 1 away from the sprocket 25, and the motor shaft of the first motor 24 is fixedly connected to one end of the first roller 21.

[0025] The adjustment structure 3 includes a fixed frame 31, a lead screw 32, a threaded block 33, a second motor 34, a slide 35, a slide rod 36, a slider 37, and an adjustment roller 38. The fixed frame 31 is fixedly installed on the side of the housing 1. The lead screw 32 is rotatably installed inside the fixed frame 31. The threaded block 33 is threaded onto the lead screw 32 and is slidably connected to the inner wall of the fixed frame 31. The second motor 34 is fixedly installed on the top of the fixed frame 31, and the motor shaft of the second motor 34 is fixedly connected to the top of the lead screw 32.

[0026] Specifically, the threaded connection between the lead screw 32 and the threaded block 33 makes the movement of the adjusting roller 38 more precise, which can finely adjust the force applied to the grass fibers during the stretching process, ensure that the grass fibers are stretched evenly, avoid overstretching or understretching, adjust the smooth movement of the adjusting roller 38, reduce mechanical vibration and impact, improve the stretching quality and reduce grass fiber damage.

[0027] Example 2:

[0028] Please see the appendix Figure 1 , Figure 2 , Figure 3 and attached Figure 7Based on Embodiment 1, the heating structure 4 includes a heating box 41, a heating wire 43, a motor frame 44, and a third motor 45. The heating box 41 is fixedly installed at the top of the box body 1. An air groove 42 is opened at the top of the heating box 41. The third motor 45 is fixedly installed inside the heating box 41 through the motor frame 44. The motor shaft of the third motor 45 is fixedly connected to a fan blade 46. The heating wire 43 is fixedly installed inside the heating box 41. Below the fan blade 46, detachable sealing plates 47 are installed at both ends of the box body 1.

[0029] Specifically, the heating structure 4 heats the external air through the heating wire 43, and the fan blade 46 introduces the hot air into the heating box 41 to ensure that the hot air is evenly distributed, avoid local overheating or undercooling of the grass fibers, and improve the tensile stability and quality.

[0030] The working principle of this utility model is as follows: This utility model is an artificial grass fiber stretching device. Heating wire 43 generates heat, and a third motor 45 drives the fan blade 46 to rotate. Air groove 42 guides air into the heating chamber 41, where it is heated by the heating wire 43. The heated air then enters the chamber 1, evenly distributing the hot air inside to heat the grass fibers. The first motor 24 is activated, and its motor shaft drives the first roller shaft 21 to rotate, simultaneously driving the sprocket 25 to rotate. The sprocket 25, through a chain belt 26, drives the second roller shaft 22 and the third roller shaft 23 to rotate, thereby pushing the grass fibers through the adjusting roller 38 for stretching. Depending on the required stretching amount of grass fibers, the second motor 34 is activated. 34 drives the lead screw 32 to rotate, and the lead screw 32 controls the threaded block 33 to move in the fixed frame 31. The threaded block 33 drives the adjusting roller 38 to slide in the slide groove 39, and at the same time drives the slider 37 to slide on the slide rod 36, thereby adjusting the position of the adjusting roller 38 and precisely controlling the stretching degree of the grass. The heating and stretching processes are carried out simultaneously to ensure that the grass is stretched at an appropriate temperature, thereby improving its flexibility and extensibility and avoiding grass breakage or deformation caused by uneven heating or excessive stretching. After the grass stretching is completed, the heating wire 43 and the third motor 45 are turned off. By pulling the handle on the sealing plate 47, the sealing plate 47 is removed, allowing the hot air inside the box 1 to be released.
