[0025] The following further describes the implementation mode of the present utility model in detail with reference to the drawings and embodiments. The following embodiments are used to illustrate the technical solutions of the present utility model, but cannot be used to limit the protection scope of the present utility model.

[0026] Embodiment:

[0027] As Figure 1 、 Figure 2 shown, the present utility model provides a thermosetting polyurethane coil runway, which includes a runway body 11 as a basic structure, bearing the weight and movement pressure of the entire runway. A runway coil is arranged above the runway body 11. The runway coil includes a polyurethane bottom plate 21, on which a polyurethane coating 22 is evenly covered by advanced mechanical spraying. Mechanical spraying can evenly distribute the polyurethane material on the bottom plate to ensure that the coating thickness at each place is correct. The runway coil is connected to the runway body 11 through polyurethane glue. This glue has excellent bonding performance and can firmly bond the runway coil to the runway body 11 to form an integral body. At the same time, a sealing layer 12 is arranged on the top surface of the runway body 11. The sealing layer 12 contacts the runway body 11, further enhancing the integrity and sealing performance of the runway. Effectively preventing the intrusion of external factors such as moisture and dust, and extending the service life of the runway. Anti-slip patterns are also arranged on the top surface of the runway coil, which can provide reliable friction force to ensure that the athlete's feet do not slip during high-speed running, sudden stops, turning and other actions, thus greatly improving the safety of the athlete on the runway.

[0028] The thickness of the polyurethane bottom plate 21 is set to 5 mm, which can provide sufficient strength and support without being too heavy to affect the elasticity and flexibility of the runway.

[0029] As Figures 3 to 7As shown, a production facility for the aforementioned thermosetting polyurethane coil runway includes a first conveyor belt 31 and a second conveyor belt 32, which together ensure an orderly production process. The first conveyor belt 31 performs the initial conveying task, transporting the polyurethane base plate 21 of the thermosetting polyurethane coil runway to the various processing stations. The second conveyor belt 32, located at one end of the first conveyor belt 31, serves as a receiving and further conveying mechanism, ensuring the continuity of the entire production process. A protective cover 33 is located above the first conveyor belt 31 and is connected to the first conveyor belt 31, forming a protective chamber. This provides a relatively closed and stable environment for the processing operations within, reducing interference from external factors such as dust and impurities. Furthermore, a spray assembly within the protective chamber operates within the chamber, ensuring the accuracy and consistency of the spraying operation. Furthermore, a drying chamber 34 is located above the first conveyor belt 31. After the polyurethane base plate 21 undergoes the spraying treatment, it enters the drying chamber 34. The drying oven 34 creates a suitable high-temperature environment, typically between 80-100°C, allowing the material sprayed onto the base plate to dry and solidify quickly. This effectively controls the curing time, ensuring product quality and performance stability; it also shortens production time and improves efficiency. A stamping assembly, located above the second conveyor belt 32, stamps the anti-slip pattern onto the runway coil. A winder 35, located at one end of the second conveyor belt 32, is responsible for orderly winding the completed coils to facilitate subsequent storage and transportation.

[0030] The spray assembly includes a support frame 41 and a spray pipe 42. The first conveyor belt 31 is located between the support frames 41 and is connected to the support frames 41. The mounting plate 43 provided on the support frame 41 provides support for the installation of the spray pipe 42. The mounting holes provided on the mounting plate 43 and the spray pipe 42 are threaded with mounting screws to achieve a detachable connection between the spray pipe 42 and the support frame 41. When the spray pipe 42 fails or requires maintenance, it can be easily and quickly removed for processing without affecting the normal operation of the entire production process. In addition, the multiple groups of nozzles provided on one side of the spray pipe 42 can ensure a wide and uniform spraying range. The sprayed liquid can fully cover the polyurethane base plate 21 on the conveyor belt, thereby ensuring the consistency of the treatment effect. A support plate 46 is provided on one side of the first conveyor belt 31, and a storage tank 44 and a water pump 45 are installed on it. The storage tank 44 is used to store the polyurethane liquid needed for spraying. The water pump 45 is the power source of the entire spraying system. It is connected to the storage tank 44 and the spray pipe 42 through connecting pipes. When the water pump 45 is started, it can extract liquid from the storage tank 44 and deliver it to the spray pipe 42 under strong pressure. Because the spray pipe 42 and the water pump 45 are connected, the liquid can be sprayed smoothly from the nozzle, achieving uniform spray treatment of the material.

[0031] As shown Figures 4 to 6 in the figure, the stamping assembly includes a workbench 51 and an electric cylinder 52. The second conveyor belt 32 is arranged inside the workbench 51, enabling the material to be conveyed to the stamping position. A plurality of connecting plates 53 arranged on the workbench 51 are connected to the second conveyor belt 32 through connecting bolts, ensuring that the relative position between the workbench 51 and the second conveyor belt 32 remains stable during the stamping process, providing a basis for stamping. The electric cylinder 52 is located above the workbench 51, and its power output provides a reliable driving force for the stamping operation.

[0032] The stamping assembly further includes a stamping template 54. As a key component that directly contacts the material and realizes stamping forming, the stamping template 54 is located between the second conveyor belt 32 and the workbench 51. The connecting sleeve 55 on the stamping template 54 cooperates with the movable rod of the electric cylinder 52. Through the connection of the assembly hole 56 and the assembly bolt 57, the detachable connection between the stamping template 54 and the electric cylinder 52 is realized, facilitating the replacement of the stamping template 54 according to different production requirements and improving the versatility and flexibility of the equipment. To ensure the smoothness of the stamping process, two sliding rods 36 are arranged on the second conveyor belt 32. Through holes corresponding to them are opened on the limiting plates 58 at both ends of the stamping template 54, and the sliding rods 36 pass through the through holes, enabling the stamping template 54 to form a slidable connection with the sliding rods 36. During stamping, the stamping template 54 can move up and down along the sliding rods 36, avoiding deviation and shaking. At the same time, two spring members 59 are arranged between the stamping template 54 and the second conveyor belt 32. The spring members 59 are sleeved on the sliding rods 36 and are connected to the second conveyor belt 32 at one end. During the stamping process, when the electric cylinder 52 pushes the stamping template 54 to stamp downward, the spring members 59 are compressed to play a certain buffering role, reducing the impact and wear on the equipment.

[0033] The specific usage mode and function of this embodiment:

[0034] During operation, the prefabricated polyurethane baseplate 21 is placed on the first conveyor belt 31. The conveyor belt is then activated, allowing the polyurethane baseplate 21 to pass through the spray assembly within the protective cover 33 for an even coating of the polyurethane material. The baseplate 21 then enters the drying oven 34 for rapid curing. After this treatment, the polyurethane baseplate 21 is transported by the first conveyor belt 31 to the second conveyor belt 32 and then to the stamping station. Depending on the type of runway coil to be produced, an appropriate stamping plate 54 is selected and installed on the electric cylinder 52. The electric cylinder 52 then drives the coil to stamp the anti-slip pattern. Throughout the production process, ensure that the storage tank 44 contains sufficient polyurethane liquid for spraying and that the water pump 45 is functioning properly to ensure continuous spraying. Regular inspection and maintenance of various components, such as the spray pipe 42 and stamping plate 54, are also required to ensure proper performance. Upon completion, the finished coil is wound up in an orderly manner using the winder 35 for subsequent storage and transportation.

[0035] During the construction and laying of the runway, the produced runway membrane is connected to the runway body 11 with polyurethane glue, and attention is paid to ensuring a firm bond and ensuring that the sealing layer 12 is in contact with the runway body 11 to achieve the integrity, sealing and anti-slip properties of the runway.
