[0025] Please refer to Figures 1 to 5 , Figure 1 which is a schematic structural diagram of a mold for plastic-steel winding pipe strip provided by an embodiment of this application. As Figure 1 shown, the mold for plastic-steel winding pipe strip includes: a template structure (101) for strip production, a strip (102), a roller assembly (13), and a cooling water tank (14). Among them, the template structure (101) for strip production is used to produce the strip (102). Further, the strip (102) can pass through the roller assembly (13) and the cooling water tank (14).

[0026] For ease of understanding, please refer to Figure 2 , in which Figure 2 is a schematic structural diagram of a strip production provided by an embodiment of this application. As Figure 2 shown, an improved strip for making plastic-steel winding pipe is provided. The strip mainly includes the following parts: a plastic wall (1), which has good corrosion resistance and compressive performance; a reinforcing rib (2), which is arranged inside the plastic wall to enhance the overall strength of the strip; and two overlapping structures, namely overlapping structure one (3) and overlapping structure two (4), whose designs are aimed at realizing the connection of the strip through a welding process, thereby forming a complete plastic-steel winding pipe. Specifically, during the manufacturing process, the strip enters the heating and winding machine through a conveying device. At this time, the plastic wall (1) softens under the action of heating, facilitating bending and forming. After reaching the predetermined shape, the overlapping structure one (3) and the overlapping structure two (4) are welded together by an automatic welding device to ensure firm connection and meet the subsequent use requirements. Embodiment

[0027] For ease of understanding, please refer to Figure 3 and Figure 4 , where Figure 3 is a schematic structural diagram of a template structure for strip production provided by an embodiment of the present application, Figure 4 is another schematic structural diagram of a template structure for strip production provided by an embodiment of the present application. Among them, Figure 4 can be used to represent Figure 3 the top view and vertical sectional view. Specifically, Embodiment 2 further shows the template structure for strip production. Among them, the key components of the template structure include: an upper cover plate (5) provided with a molten plastic injection port (11); a transition plate (6) for guiding the flow of molten plastic; a discharge plate (7) for helping the strip to be smoothly demolded; a runner plate (12) forming a channel for the composite of molten plastic and steel strip; and a core plate composed of an upper core plate (9) and a lower core plate (10) with a channel in the middle for the steel strip to pass through. During specific operation, the molten plastic is injected through the injection port (11) and flows in the runner groove, and finally combines with the steel strip passing through the core plate channel to form a strip (8) with certain strength and stiffness.

[0028] It should be understood that the template structure (101) for strip production and the strip (102) included in the above can correspond to the structure in Figure 1 . Specifically, Figure 3 the template structure (101) for strip production in Figure 1 can include the upper cover plate (5) in Figure 3 , the transition plate (6) in Figure 3 , the discharge plate (7) in Figure 3 , the upper core plate (9) in Figure 3 and the lower core plate (10) in Figure 3 . Among them, Figure 1 the strip (102) in Figure 3 is the strip (8) in Embodiment

[0029] For ease of understanding, please refer to Figure 5 , where Figure 5 is a schematic structural diagram of a roller assembly provided by an embodiment of the present application. Specifically, after the strip is demolded, Embodiment 3 describes the strip cooling and shaping process. As described above Figure 1 and Figure 5As shown, the strip enters the roller assembly (13) in the cooling water tank (14). The roller assembly (13) includes rollers (15), a fixing frame (16), an upper plate (17), a spring (18), and a chute (19). Among them, the fixing frame (16) is installed at the bottom of the water tank and is provided with a chute (19), and the rollers (15) can slide along the chute (19). Further, under the action of the spring (18), the rollers (15) are in close contact with the strip, and the strip is cooled and shaped through the channel between the rollers and the upper plate (17). The spacing between the rollers can be adjusted according to different specifications of the core plates. By increasing or decreasing the gaskets between the rollers, precise control of the roller spacing can be achieved.

[0030] The design of the roller assembly in this embodiment aims to improve the dimensional accuracy and surface quality of the strip, ensuring that the final product quality of the plastic-steel winding pipe meets the industry standards.

[0031] In summary, this application provides a mold for plastic-steel winding pipe strips. Among them, this application solves the problems of low production efficiency of current strips and the mold can only be applicable to strips of a single specification. Specifically, by pressing the rollers to replace the current plastic shaping method of extruding and rubbing the strip through a template, the resistance to the strip operation is reduced, the production efficiency of the strip is improved. At the same time, the spacing between the rollers can be adjusted according to actual needs, improving the applicable range of the equipment.

[0032] This application realizes the rapid adjustment of the roller spacing through the sliding adjustment mechanism of the roller rod. Further, through the design of the elastic force component, the pressure between the rollers and the strip is ensured to be uniform. Moreover, through the design of the mold structure, the dimensional accuracy and production efficiency of the strip are improved. Generally speaking, this application improves the production efficiency and product quality of plastic-steel winding pipe strips. It not only reduces the mold adjustment time and improves production flexibility. But also extends the service life of the mold and reduces the maintenance cost. Furthermore, it is applicable to the production of strips of various specifications, improving the versatility of the equipment.
