Description

Technical Field

[0001] This application relates to the field of artificial turf preparation technology, specifically a cooling device for preparing grass fibers. Background Technology

[0002] Artificial turf has been widely used in sports, landscaping, and leisure fields, and its core quality depends on the performance of the grass fibers. In the grass fiber manufacturing process, after the molten polymer is extruded through a spinneret, it needs to be cooled and shaped immediately. This process directly determines the final mechanical strength, morphological stability, and surface gloss of the grass fibers.

[0003] Existing technologies generally employ open, large-scale cooling water tanks to centrally cool the extruded straw fibers. However, this cooling method has the following shortcomings in practical use:

[0004] 1. Multiple grass fibers are transported in parallel in a wide water tank. They are easily tangled and shaken due to water flow disturbance, resulting in strand breakage, broken fibers and surface scratches, which seriously affect product quality and production efficiency.

[0005] 2. The cooling water in the entire water tank is in a relatively static or slow-flowing state, resulting in low heat exchange efficiency and easy formation of localized excessively high water temperatures. This leads to uneven cooling of the straw fibers, internal stress, and consequently, bending, warping, and batch-to-batch color differences in the straw fibers.

[0006] 3. Existing cooling water tanks often carry a large amount of cooling water. When continuously cooling the grass fibers, the cooling water in the tank will gradually heat up due to heat absorption. After the cooling water heats up, it cannot cool down quickly, which seriously affects the subsequent cooling effect on the grass fibers. If cooling water cooling equipment or circulation conveying equipment is added, it will increase the cost and waste resources.

[0007] Therefore, existing cooling devices are no longer able to meet the production requirements of high-quality artificial grass fibers in terms of cooling uniformity, stability and production efficiency. There is an urgent need for a grass fiber cooling device that can achieve grass fiber isolation and efficient and uniform cooling. Summary of the Invention

[0008] To overcome the shortcomings of the prior art, this utility model discloses a cooling device for grass fiber preparation. By setting up multiple independent parallel cooling tanks and a forced circulation water channel, this utility model constructs an isolated and directional high-efficiency cooling unit, which effectively solves the technical problems of grass fibers being easily entangled, shaking, and unevenly cooled during the cooling process.

[0009] To achieve the above objectives, this application provides the following technical solution:

[0010] A cooling device for preparing grass fibers includes a water tank for storing cooling water, and further includes:

[0011] An input roller, located at one end of the water tank, is used to guide the grass fibers into the water tank;

[0012] The cooling mechanism is located inside the water tank and above the surface of the cooling water in the tank, and is used to cool and lower the temperature of the grass fibers.

[0013] The output roller, located at the other end of the water tank, is used to guide the grass fibers out of the water tank;

[0014] The cooling mechanism includes:

[0015] Several cooling tanks are arranged in parallel sequence. The two ends of the cooling tanks correspond to the input roller and the output roller, respectively. The two ends of the cooling tanks are respectively provided with water inlet and water outlet, and there is a certain gap between the two ends and the inner wall of the adjacent water tank.

[0016] A water pump, located inside a water tank and connected to the inlets of several cooling tanks, is used to input cooling water into the cooling tanks and drive the cooling water to flow directionally along the cooling tanks, forming a cooling path for the circulating flow of cooling water.

[0017] The pressing component, located at the top of the cooling tank, is used to confine the grass fibers within the cooling path of the cooling tank and ensure that they are submerged in cooling water.

[0018] Furthermore, the pressing component includes:

[0019] A rectangular frame that can be detachably installed on the upper part of the cooling tank and is compatible with the upper opening of the cooling tank;

[0020] The lower pressure roller is rotatably mounted inside a rectangular frame, with its roller surface extending into the cooling tank.

[0021] Furthermore, guide rollers for guiding and conveying the grass fibers are rotatably installed on the upper part of both ends of the cooling tank.

[0022] Furthermore, both ends of the cooling tank opening are provided with vertical plates that abut against the end face of the rectangular frame. The surface of the vertical plate is provided with through holes that penetrate the vertical plate, and the end face of the rectangular frame is provided with mounting holes that correspond to and fit the through holes.

[0023] Furthermore, a notch is provided on the upper part of the upright plate, and the guide roller is rotated and installed in the notch.

[0024] Furthermore, the water inlet is located at the end of the cooling tank facing the output roller, and the water outlet is located at the end of the cooling tank facing the input roller.

[0025] Furthermore, the water tank is equipped with a horizontally positioned mounting plate, with gaps between the two ends of the mounting plate and the inner walls of the two ends of the water tank, and the cooling tank can be detachably installed on the upper part of the mounting plate.

[0026] Furthermore, mounting ports are provided at the upper part of both ends of the water tank, and the input roller and output roller are rotatably installed in the mounting ports.

[0027] Compared with the prior art, the beneficial effects of this application are:

[0028] By setting up multiple independent parallel cooling tanks, the parallel grass fibers are physically isolated, which not only effectively avoids the grass fibers from tangling, shaking and rubbing together in the water, fundamentally solving the problems of "thread twisting" and surface damage, but also ensures that each grass fiber is cooled under the same conditions, greatly improving the uniformity of cooling.

[0029] By driving the cooling water through a water pump to flow in a directional and circulating manner within an independent cooling tank, a forced convection heat exchange environment is formed. This not only significantly improves cooling efficiency, but also greatly accelerates the heat dissipation and cooling of the cooling water after it flows out of the cooling tank and into the water tank, providing strong support for the subsequent cooling of the grass fibers.

[0030] By placing the inlet and outlet at opposite ends of the cooling tank and preferably directing the cooling water flow in the opposite direction to the direction of the grass fibers, a highly efficient "countercurrent heat exchange" mode is constructed. This ensures that the grass fibers are always in contact with fresher cooling water at a lower temperature during the transport process, which not only significantly improves the cooling efficiency but also effectively removes heat, prevents local water temperature rise, and results in a better and more stable cooling effect.

[0031] The detachable pressing component not only facilitates the threading and initial positioning of the grass fibers, but also reliably confines the grass fibers within the preset immersion depth and path during the cooling process, ensuring the stability of the cooling process. Furthermore, it facilitates daily cleaning, maintenance, and component replacement, reducing equipment operation and maintenance costs.

[0032] By setting guide rollers at both ends of the cooling tank, the straw fibers roll and rub against the rollers when entering and leaving the cooling tank, avoiding rigid scraping against the tank wall. This not only effectively prevents wear and fuzzing on the surface of the straw fibers and ensures the quality of the finished straw fibers, but also reduces running resistance and makes the conveying smoother.

[0033] This invention constructs an isolated and directional high-efficiency cooling unit by setting up multiple independent parallel cooling tanks and forced circulation water channels. It fundamentally solves the technical problems of grass fibers being easily tangled, shaking, and unevenly cooled during the cooling process, achieving high-quality, high-efficiency, and uniform cooling of grass fibers, and significantly improving the operability and maintainability of the equipment.

[0038] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0039] Please refer to the instruction manual appendix. Figure 1-3 This utility model provides a technical solution:

[0040] Example 1: A cooling device for preparing grass fibers includes a water tank 1 for storing cooling water. The upper part of the tank wall at both ends of the water tank 1 is provided with an installation port 1.1. An input roller 2 for guiding grass fibers into the water tank 1 is rotatably installed in the installation port 1.1 at one end of the water tank 1, and an output roller 4 for guiding grass fibers out of the water tank 1 is rotatably installed in the installation port 1.1 at the other end of the water tank 1.

[0041] A mounting plate 1.2 is located above the cooling water surface in the water tank 1. There are gaps between the two ends of the mounting plate 1.2 and the inner walls of both ends of the water tank 1. A cooling mechanism 3 for cooling the straw fibers is mounted on the mounting plate 1.2. Specifically, the cooling mechanism 3 includes a cooling tank 3.1, a pressing component 3.2, and a water pump 3.3. The cooling tank 3.1 is mounted on the upper part of the mounting plate 1.2, and its two ends correspond to the input roller 2 and the output roller 4, respectively. The cooling tank 3.1 has an inlet 3.1.1 and an outlet 3.1.2 at its two ends, respectively. The water pump 3.3 is located inside the water tank 1 and is connected to the cooling tank 3.1. The inlet 3.1.1 is connected to the cooling tank 3.1 and is used to input cooling water into the cooling tank 3.1 and drive the cooling water to flow in a directional manner along the cooling tank, forming a cooling path for the cooling water circulation. By reasonably setting the diameter of the outlet 3.1.2 and the water inlet 3.1.1, it can be ensured that the cooling tank 3.1 always maintains an appropriate amount of cooling water, thereby providing strong support for the subsequent immersion cooling of the grass fibers. In order to achieve cooling and temperature reduction of multiple grass fibers and avoid the grass fibers from tangling during the cooling process, multiple cooling tanks 3.1 can be set, and multiple cooling tanks 3.1 are arranged in an orderly manner along the width direction of the water tank 1.

[0042] The pressing component 3.2 is located on the upper part of the cooling tank 3.1 and is used to confine the grass fibers within the cooling path of the cooling tank 3.1 and ensure that they are submerged in cooling water. Specifically, the pressing component 3.2 includes a rectangular frame 3.2.1 and a pressing roller 3.2.2. The rectangular frame 3.2.1 is installed on the upper part of the cooling tank 3.1 and is adapted to the upper end of the groove of the cooling tank 3.1. The pressing roller 3.2.2 is rotatably installed inside the rectangular frame 3.2.1, and the roller surface of the pressing roller 3.2.2 extends into the cooling tank 3.1. In order to ensure that the grass fibers can be effectively cooled and transported along the cooling tank 3.1, multiple pressing rollers 3.2.2 are provided and spaced apart along the length of the rectangular frame 3.2.1.

[0043] During the cooling process, multiple grass fibers are transported from multiple cooling tanks 3.1 within the cooling mechanism 3. The circulating cooling water not only provides more efficient cooling for the grass fibers, but also dissipates heat quickly during circulation, thus preventing the cooling water from overheating and affecting the subsequent cooling effect on the grass fibers.

[0044] In Example 2, when the grass fibers are input to and output from the cooling tank 3.1, they are prone to friction with the upper edge of the tank walls at both ends of the cooling tank 3.1, which can lead to wear of the grass fibers in severe cases. Therefore, guide rollers 3.1.4 are rotatably installed on the upper part of both ends of the cooling tank 3.1 to guide and convey the grass fibers. The guide rollers 3.1.4 can guide and convey the grass fibers, effectively preventing friction damage to the grass fibers.

[0045] In Example 3, to facilitate the placement of grass fibers into the cooling tank 3.1, both ends of the cooling tank 3.1 are provided with upright plates 3.1.3 that abut against the end face of the rectangular frame 3.2.1. The upright plates 3.1.3 have through holes 3.1.3.2 penetrating them. The end face of the rectangular frame 3.2.1 has mounting holes 3.2.1.1 that correspond to and fit the through holes 3.1.3.2. The corresponding mounting holes 3.2.1.1 and through holes 3.1.3.2 are connected by screws or rivets, thereby enabling the pressing component 3.2 to be... The detachable pressing component 3.2 can be removed when the grass fibers are guided and placed into the cooling tank 3.1, and then reinstalled after the grass fibers are placed in the cooling tank 3.1. This greatly facilitates the guidance, placement, and conveying of the grass fibers. Correspondingly, in order to enable the guide roller 3.1.4 to effectively guide and convey the grass fibers and prevent the grass fibers from rubbing against the rectangular frame 3.2.1, a notch 3.1.3.1 is provided on the upper part of the upright plate 3.1.3, and the guide roller 3.1.4 is rotatably installed in the notch 3.1.3.1.

[0046] In Example 4, to improve the cooling effect of the circulating cooling water in the cooling tank 3.1 on the grass fibers, the inlet 3.1.1 is located at the end of the cooling tank 3.1 facing the output roller 4, and the outlet 3.1.2 is located at the end of the cooling tank 3.1 facing the input roller 2. The flow direction of the cooling water is reversed with the conveying direction of the grass fibers. This not only allows the cooling water to cool the grass fibers more fully and efficiently, but also ensures that the grass fibers are always in contact with the cool water at a lower temperature during the conveying process, rather than the cool water that has absorbed heat and increased in temperature, which greatly improves the cooling effect of the grass fibers.
