[0002] Precast plastic running tracks are a type of plastic sports surface made of precast rolls in a factory. They have a flat and solid structure and are suitable for track and field venues. They are produced on factory assembly lines with fixed material formulas and processes, resulting in stable performance that is not affected by the construction site environment. They are mainly used in track and field venues such as schools and stadiums that require high load-bearing capacity and long-term use.

[0003] For example, the authorized patent with publication number CN220433323U (environmentally friendly prefabricated plastic running track) includes a support plate;

[0004] The aforementioned existing technology employs a method where the connecting block and the connecting groove are engaged, and the magnetic block at one end of the connecting block is magnetically connected to the iron sheet inside the connecting groove. This improves the stability of the connection between the connecting block and the connecting groove, solving the problems of poor firmness and unevenness in prefabricated plastic running tracks. However, in this structure, under long-term use, the internal structure of the magnetic block becomes fragile and has poor impact resistance, leading to damage to the connecting components. This affects the firmness of the plastic running track assembly, causing cracking, warping, or breakage at the joints, affecting the flatness of the plastic running track and reducing its service life. Therefore, there is an urgent market need to develop a cutting device for rotor sleeve stamping die processing to help solve the existing problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly prefabricated plastic running track, comprising an environmentally friendly prefabricated plastic running track body, wherein the environmentally friendly prefabricated plastic running track body is provided with a fixing agent sealing layer, an elastic particle layer, a sealing layer and a spray surface layer from bottom to top, the surface of the spray surface layer is coated with a marking layer, the bottom surface of the elastic particle layer is provided with a plurality of water vapor circulation holes, the bottom surface of the fixing agent sealing layer is provided with a mesh layer, and a joint strip is provided at the connection between two adjacent environmentally friendly prefabricated plastic running track bodies, and a reinforcing base plate is provided at the bottom end of the joint strip.

[0007] In a further embodiment, the mesh layer is made of resin or plastic, the length of the mesh layer is the same as the length of the environmentally friendly prefabricated plastic track body, and the width of the mesh layer is shorter than the width of the environmentally friendly prefabricated plastic track body.

[0008] In a further embodiment, the reinforcing substrate has multiple hexagonal perforations inside, and the thickness of the reinforcing substrate is the same as the thickness of the mesh layer.

[0009] In a further embodiment, the seam strip is connected to the reinforcing base plate in a T-shaped structure, and the seam strip has a vent hole at the position aligned with the elastic particle layer, and the vent hole is circular in shape.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-7 This utility model provides an embodiment of an environmentally friendly prefabricated plastic running track, comprising an environmentally friendly prefabricated plastic running track body 1. The environmentally friendly prefabricated plastic running track body 1 is provided with, from bottom to top, a fixing agent sealing layer 6, an elastic particle layer 4, a sealing layer 3, and a spray surface layer 8. The surface of the spray surface layer 8 is coated with a marking layer 2. The bottom surface of the elastic particle layer 4 is provided with several water vapor circulation holes 5. The bottom surface of the fixing agent sealing layer 6 is provided with a mesh layer 7. A joint strip 9 is provided at the connection point of two adjacent environmentally friendly prefabricated plastic running track bodies 1, and a reinforcing base plate 11 is provided at the bottom end of the joint strip 9. Through fixing... The sealing layer 6 is used to increase the firmness of the environmentally friendly prefabricated plastic track body 1. The elastic particle layer 4 is used to absorb the impact force when athletes land, reducing damage to joints and muscles. The sealing layer 3 is used to seal the surface of the elastic particle layer 4, increasing wear resistance. The spray layer 8 is used to spray paint and protect the surface. The marking layer 2 is used to mark the track and plan the track. The joint strip 9 is used to seal the gaps between the assembly of two adjacent environmentally friendly prefabricated plastic track bodies 1. The reinforcing base plate 11 is used to increase the firmness of the connection between the joint strip 9 and the base surface.

[0024] The mesh layer 7 is made of resin or plastic. The length of the mesh layer 7 is the same as the length of the environmentally friendly prefabricated plastic track body 1, and the width of the mesh layer 7 is shorter than the width of the environmentally friendly prefabricated plastic track body 1. By using different widths, installation positions for the reinforcing base plate 11 can be reserved on both sides, making the installation of the reinforcing base plate 11 more secure. The reinforcing base plate 11 has multiple hexagonal punches inside, and the thickness of the reinforcing base plate 11 is the same as the thickness of the mesh layer 7. The hexagonal punches can increase the contact area between the adhesive and the reinforcing base plate 11, increasing the installation firmness of the reinforcing base plate 11.
