Description

Technical Field

[0001] This utility model relates to the field of artificial turf production, specifically a drying device for artificial turf production. Background Technology

[0002] In the production of artificial turf, drying equipment plays a crucial role. It not only cures the adhesive layer on the turf to ensure its quality and performance, but also considers factors such as production efficiency and safety. The performance of the drying equipment directly affects the final quality of the turf; therefore, it occupies an indispensable position in the production process.

[0003] Currently, existing drying equipment has several shortcomings in the adhesive layer curing stage. Firstly, poor adhesive layer smoothing can lead to uneven distribution, directly impacting subsequent curing and overall turf quality. Secondly, precise temperature control during curing makes it difficult to differentiate treatment based on the different needs of the turf's front and back sides, potentially causing localized overheating or insufficient curing, damaging the grass fibers or reducing curing quality. Furthermore, cooling efficiency and uniformity need improvement; uneven cooling can lead to stress concentration in the adhesive layer, affecting turf durability. Moreover, there is a lack of effective perforation mechanisms to improve turf drainage, failing to meet the high drainage requirements of actual use. These problems not only affect turf quality but also hinder further improvements in production efficiency. Summary of the Invention

[0004] In order to overcome some of the problems mentioned in the background above, this utility model provides a drying device for artificial turf production.

[0005] The technical solution adopted by this utility model is as follows: A drying device for artificial turf production, comprising a box body, wherein the following components are arranged sequentially along the direction of turf travel within the box body: A leveling roller, which contacts the adhesive surface of the turf and is used to spread the adhesive layer evenly; A wind-heating mechanism, comprising a wind-heating module and air guide plates, wherein the air guide plates are disposed on both sides of the wind-heating module, and the wind-heating module is used to initially cure the adhesive layer of the turf; The curing mechanism is symmetrically arranged on both sides of the turf; A detector is provided corresponding to the curing mechanism, and the detector is used to detect the state of the turf adhesive layer; The air-cooling mechanism is symmetrically arranged on both sides of the turf to cool the cured turf.

[0006] Furthermore, a punching mechanism is provided on the rear side of the air-cooling mechanism, which is used to punch drainage holes in the turf. The punching mechanism includes a punching roller and a drive motor. The drive motor drives the punching roller to rotate. The punching roller includes a drive roller, a heating layer, multiple support rods, and multiple needles. One end of the drive roller is connected to the drive motor. A heating layer is provided on the outer side of the drive roller. The multiple support rods are distributed circumferentially along the outer wall of the heating layer. The multiple needles are arranged in an array along the longitudinal direction of the support rods. The bottom of the needle is connected to the heating layer, and the support rod includes a heat insulation rod; The outer side of the support rod is also provided with multiple retaining rings, which are used to fasten the support rod.

[0007] Furthermore, the air-heating module includes an air-heating pipe and multiple hot air outlets. The multiple hot air outlets are arranged in pairs along the longitudinal direction of the air-heating pipe. An angle is formed between the hot air outlets and the surface of the turf. The circulation angle of the hot air is adjusted by the air guide plate.

[0008] Furthermore, the rotation direction of the leveling roller is opposite to the direction of travel of the turf, and the linear velocity ratio between the contact surface of the leveling roller and the turf is 1:1.2-1.5.

[0009] Furthermore, the detector is provided in two parts, and the two detectors are respectively disposed on both sides of the curing mechanism; The detector includes a connecting plate, a telescopic rod, and a probe head. The telescopic rod is disposed between the connecting plate and the probe head, and the probe head is in contact with the adhesive layer of the turf.

[0010] Furthermore, the curing mechanism includes a fixed shell, a cooling water pipe, a reflector, and multiple heating pipes. The reflector is disposed inside the fixed shell, the cooling water pipe is disposed between the reflector and the fixed shell, the reflector is wavy, and the heating pipes are disposed outside the reflector.

[0011] Furthermore, the air-cooling mechanism includes an air-cooling pipe and multiple air inlets, which are arranged sequentially along the longitudinal direction of the air-cooling pipe. The air inlets are configured with a multi-hole spray structure and face the surface of the turf.

[0012] Furthermore, it also includes two guide rollers, which are respectively disposed on both sides of the curing mechanism.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: More uniform adhesive layer application: The leveling roller is positioned at the forefront of the turf's movement direction, rotating in the opposite direction to the turf's travel. Its linear velocity ratio with the turf contact surface is precisely controlled within the range of 1:1.2 to 1.5. This design eliminates uneven adhesive layer application, appropriately stretches and compacts the turf, significantly improving the quality of the adhesive layer and thus enhancing the smoothness and durability of the artificial turf.

[0014] Superior curing effect: Two symmetrical curing mechanisms are located on the front and back of the turf, respectively, ensuring uniform curing on both sides. Simultaneously, the upper curing mechanism has a higher temperature than the lower one, preventing excessive heat from damaging the grass fibers.

Therefore, they should not be construed as limitations on this utility model.

[0020] like Figures 1-8 As shown, in some embodiments, a drying device for artificial turf production includes a housing 1. Inside the housing 1, along the direction of travel of the turf 3, the following components are arranged in sequence: The leveling roller 9 is located at the foremost part of the turf 3 in the direction of movement and is in direct contact with the adhesive surface of the turf 3. Its main function is to smooth the adhesive layer applied to the turf 3 and ensure that the adhesive layer is evenly distributed.

[0021] The air-heating mechanism 8 consists of an air-heating module 81 and an air guide plate 82. The air guide plate 82 is placed on both sides of the air-heating module 81. The main function of the air-heating module 81 is to use hot air to perform preliminary curing treatment on the adhesive layer on the turf 3, so as to facilitate subsequent testing and curing of the adhesive layer.

[0022] The curing mechanism 7 consists of two units, symmetrically positioned on both sides of the turf 3 to ensure uniform curing on both sides. This symmetrical design guarantees consistent curing quality and further enhances the overall performance of the turf 3 through precise temperature control. Specifically, the two curing mechanisms 7 operate at different temperatures, with the upper mechanism 7 operating at a higher temperature than the lower one. This is primarily to prevent excessive heat in the lower mechanism 7, which could damage the grass fibers on the turf 3.

[0023] Detector 6, which is set in correspondence with curing mechanism 7, is mainly responsible for detecting the state of the adhesive layer of turf 3 to ensure the quality of the curing process.

[0024] The air-cooling mechanism 4, which consists of two units, is symmetrically arranged on the front and back sides of the turf 3. Its function is to cool the turf 3 after it has been cured, so as to achieve rapid cooling of the cured adhesive layer and thus improve production efficiency. The air-cooling mechanism 4 ensures the uniformity and efficiency of the cooling process through optimized air duct design.

[0025] Furthermore, in some embodiments, a perforation mechanism 2 is provided on the rear side of the air-cooling mechanism 4. The main function of the perforation mechanism 2 is to punch drainage holes in the turf 3 so that water on the lawn can be quickly discharged during use, thereby improving the performance and lifespan of the artificial turf.

[0026] The perforation mechanism 2 includes a perforation roller 21 and a drive motor 22. The drive motor 22 is responsible for driving the perforation roller 21 to rotate so as to perform the perforation operation on the turf 3.

[0027] The punching roller 21 consists of a drive roller 211, a heating layer 212, multiple support rods 213, and multiple needles 214. One end of the drive roller 211 is connected to a drive motor 22 to ensure that the drive roller 211 can obtain sufficient power to rotate. The outer side of the drive roller 211 is provided with a heating layer 212, which is used to heat the needles 214 during the punching operation to improve punching efficiency and quality.

[0028] Multiple support rods 213 are circumferentially distributed along the outer wall of the heating layer 212. Their main function is to support and fix the heating layer 212, ensuring its stable operation during the perforation process. Multiple needles 214 are arranged in an array along the longitudinal direction of the support rods 213. They directly contact the turf 3 and are responsible for perforating drainage holes in the turf 3. The precise arrangement and distribution of the needles 214 ensures the uniformity and consistency of the drainage holes, which is crucial for the drainage performance of the artificial turf.

[0029] The bottom of the needle 214 is connected to the heating layer 212, which ensures that the needle 214 receives sufficient heat during the piercing operation, thereby improving the efficiency and quality of piercing. The support rod 213 includes a heat insulation rod, which prevents heat from being transferred to other parts besides the needle 214, avoiding unnecessary damage to the turf 3; the use of heat insulation material not only protects the turf 3, but also ensures the efficiency and safety of the piercing operation.

[0030] The outer side of the support rod 213 is also provided with multiple fixing rings 215. The main function of the fixing rings 215 is to fasten the support rod 213, ensuring that the support rod 213 can work stably during the drilling operation and will not shift its position due to equipment vibration, thereby ensuring the accuracy and quality of the drilling operation.

[0031] like Figure 4 and Figure 6 As shown, in some embodiments, the air-heating module 81 includes an air-heating pipe 811 and multiple hot air outlets 812. These hot air outlets 812 are arranged in pairs along the longitudinal direction of the air-heating pipe 811 to ensure that hot air can evenly cover the entire surface of the turf 3. A specific angle is provided between the hot air outlets 812 and the surface of the turf 3. This angle is designed to optimize the efficiency of hot air contact with the turf 3, thereby improving the drying effect. In addition, the circulation angle of the hot air can be flexibly controlled by adjusting the air guide plate 82, making the drying process more efficient and uniform, and ensuring the quality and performance of the artificial turf.

[0032] like Figure 2 and Figure 4 As shown, in some embodiments, the rotation direction of the leveling roller 9 is opposite to the direction of travel of the turf 3. This design ensures that the adhesive layer of the turf 3 is uniformly treated when passing through the leveling roller 9, thereby improving the quality of the adhesive layer of the turf 3. Furthermore, the linear velocity ratio of the contact surface between the leveling roller 9 and the turf 3 is precisely controlled within the range of 1:1.2 to 1.5. Such a velocity ratio ensures that the turf 3 is properly stretched and compacted during the drying process, further guaranteeing the smoothness and durability of the artificial turf. Through this design, both the production efficiency and quality of the artificial turf are significantly improved.

[0033] Specifically, the counter-rotation of the leveling roller 9 and the forward movement of the turf 3 create a counterforce, which helps to eliminate uneven application of the adhesive layer that may occur during production. Simultaneously, by precisely controlling the linear velocity ratio of the contact surfaces of the leveling roller 9 and the turf 3, the pressure between the turf 3 and the leveling roller 9 can be effectively adjusted.

[0034] like Figures 2-5 As shown, in some embodiments, the device includes two detectors 6, which are respectively disposed on both sides of the curing mechanism 7.

[0035] Each detector 6 includes a connecting plate 62, a telescopic rod 61, and a probe head 63, wherein the telescopic rod 61 is disposed between the connecting plate 62 and the probe head 63. The design of the telescopic rod 61 allows the probe head 63 to be precisely adjusted in the vertical direction to ensure direct contact with the adhesive layer of the turf 3.

[0036] Specifically, the probe 63 contacts the adhesive layer of the turf 3. This direct contact method allows the equipment to more accurately detect the state of the adhesive layer of the turf 3, thereby adjusting the curing parameters to ensure the quality of the turf 3 and ensure that the quality of the final product meets the standards.

[0037] In addition, by placing the detectors 6 on both sides of the curing mechanism 7, comprehensive inspection of the turf 3 can be achieved. This all-round inspection layout ensures that every part of the turf 3 can be meticulously monitored, avoiding uneven drying and curing caused by incomplete inspection, thereby improving the uniformity and efficiency of the drying and curing process.

[0038] Furthermore, in some embodiments, the curing mechanism 7 includes a fixed housing 71, a cooling water pipe 72, a reflector 73, and a plurality of heating pipes 74. Specifically, the reflector 73 is disposed inside the fixed housing 71, while the cooling water pipe 72 is cleverly arranged between the reflector 73 and the fixed housing 71, forming an effective cooling structure. Specifically, cooling water (temperature 20-25°C) circulates in the cooling water pipe 72 to prevent the fixed housing 71 from overheating.

[0039] In addition, the reflector 73 is designed in a wave shape and is made of polished aluminum plate with a reflectivity of ≥90%. The reflective surface of the reflector 73 faces outward, while the heating tube 74 is installed on the outside of the reflector 73. The reflector 73 ensures that heat can be evenly transferred to the turf 3, thereby achieving the effect of rapid drying and curing.

[0040] like Figure 2 and Figure 7 As shown, in some embodiments, the air-cooling mechanism 4 includes an air-cooling pipe 41 and a plurality of cold air outlets 42, which are arranged sequentially along the longitudinal direction of the air-cooling pipe 41. Each cold air outlet 42 is designed with a porous spray structure to uniformly spray cold air onto the surface of the turf 3. This design ensures that the cold air can efficiently cover the entire turf surface, thereby achieving the purpose of rapidly and uniformly cooling the turf 3.

[0041] The working principle of this air-cooling mechanism 4 is that cold air is delivered to various cold air outlets 42 through the air-cooling pipes 41, and then the cold air is evenly sprayed onto the surface of the turf 3 through the multi-hole spray structure of these cold air outlets 42. This uniform spraying method can effectively avoid the problem of inconsistent drying effect caused by uneven distribution of cold air, thereby ensuring the consistency and reliability of drying quality. In addition, since each cold air outlet 42 has a multi-hole spray structure, multiple fine cold air jets can be formed when cold air is sprayed. These jets can penetrate deeper into the fibers of the turf 3, thereby improving cooling efficiency and effect.

[0042] Furthermore, in some embodiments, the device also includes two guide rollers 5, which are carefully designed and respectively arranged on both sides of the curing mechanism 7 to guide the artificial turf 3 smoothly through the drying and curing process, ensuring the uniformity and efficiency of the drying and curing process.
