Specifically, it discloses the following: a mixture of cement, stone powder, and fiberglass cloth in a weight ratio of 1:1:0.1-0.5, wherein 20%-40% of the total weight of cement and stone powder is added to water to form a slurry. This application uses fiberglass cloth as a skeleton, reducing production costs and producing pipes with small diameters and thin walls. These pipes exhibit superior mechanical strength compared to plastic pipes, overcome the aging issues of plastic pipes, are corrosion-resistant, and have extended service life. However, in practical use, it has been found that adding a cement shell to the outside of the plastic drainage pipe can also effectively improve its service life and ensure structural stability during use. Furthermore, adding fiberglass cloth to the cement shell can effectively increase its strength and service life.

[0003] The purpose of this application is to explore a production device for the composite production process of plastic drainage pipes with fiberglass cloth and cement shell, so as to improve the production efficiency and quality of the above-mentioned composite pipes. Summary of the Invention

[0004] The purpose of this application is to provide a glass fiber cement shell winding device for plastic drainage pipes, which can realize the composite of polyvinyl chloride pipes and cement pipes, and ensure that glass fiber and cement mortar are injected simultaneously during the composite process, thereby improving the production efficiency of cement products.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] The fiberglass cement shell winding device for plastic drainage pipes described in this application includes a base, on which a pair of frames are arranged. Each frame is equipped with a baffle and a fixed end. A mandrel is positioned between the baffle and the fixed end. An outer cylinder is positioned axially on the mandrel, and the outer cylinder and mandrel are coaxially arranged, forming a molding chamber between them. Both ends of the outer cylinder are limited by the fixed end and the baffle. One end of the mandrel is connected to a rotating shaft, which is connected to a drive motor. The drive motor is connected to a control unit within a rotary control cabinet. The other end of the mandrel is connected to the outer cylinder via a sizing sleeve. The molding chamber communicates with a grouting hole located on the outer cylinder. A fiberglass cloth traction seam is machined through the outer cylinder, allowing the fiberglass cloth to pass through and wind around the mandrel. The fiberglass cloth is located on a yarn frame connected to the base.

[0007] As one of the preferred technical solutions, in this application, the outer cylinder is further provided with a cylinder interlayer on its outer wall. The cylinder interlayer is connected to the drying hole, and the drying hole has an inlet pipe and an outlet pipe.

[0025] The structure and connections of the remaining parts are the same as those described in Embodiment 1, and will not be repeated here to avoid unnecessary detail. Those skilled in the art can fully understand the technical solutions described in this embodiment based on the above embodiments.

[0026] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles of these technical features in this technical solution, so as to help those skilled in the art to fully understand the technical solution and reproduce it.

[0027] In this application, the base 16 is used to support and place the yarn frame 9 and the frame 17, and the base 16 can be made of precast concrete.

[0028] In this application, the frame 17 includes a left frame and a right frame. The left frame is connected to a drive motor 2, a rotating shaft 3, a rotary control cabinet 4, and a fixed end 18. The drive motor 2 is used to drive the rotating shaft 3 to rotate. The rotary control cabinet 4 is used to control the start and stop of the drive motor 2 through an internal control unit. The fixed end 18 is used to connect to the outer cylinder 7. The rotating shaft 3 is connected to one end of the mandrel 1 to drive the mandrel 1 to rotate around its own central axis relative to the outer cylinder 7.

[0029] In this application, a baffle 6 is provided on the right frame, and the baffle 6 is connected to the other end of the outer cylinder 7. A sizing sleeve 5 is provided at the end of the mandrel 1 located in the direction of the baffle 6. The sizing sleeve 5 is located between the inner wall of the outer cylinder 7 and the outer wall of the mandrel 1, which can support the mandrel 1 and ensure the relative rotation of the mandrel 1 and the outer cylinder 7. One end of the mandrel 1 is blocked by the rotating shaft 3 and can be driven by the rotating shaft 3. The other end of the mandrel 1 is connected to the sizing sleeve 5 and then contacts the baffle 6. The above structure can prevent cement mortar in the molding chamber 14 from entering the interior of the mandrel 1.

[0030] In this application, the outer cylinder 7 is also connected to a grouting hole 8, which communicates with the molding chamber 14 formed by the outer cylinder 7 and the core rod 1. Cement mortar is injected into the molding chamber 14 through the grouting hole 8 and forms within the molding chamber 14, thus making the cement mortar and the core rod 1 integral. The grouting hole 8 can also be used to discharge heated gases from the cement mortar when steam is introduced. Alternatively, several vent holes communicating with the molding chamber 14 can be distributed on the outer cylinder 7. During the cement mortar pouring process, these vent holes are sealed with plugs. During steam heating, the plugs are removed, allowing the heated gases from the cement mortar to be discharged.

[0031] During the above process, the mandrel 1 can also be wound with the fiberglass cloth 10. One end of the fiberglass cloth 10 is connected to the mandrel 1, and the other end of the fiberglass cloth 10 passes through the fiberglass cloth traction seam 11 processed on the outer cylinder 7 and is connected to the yarn frame 9. When the mandrel 1 rotates with the rotating shaft 3, the mandrel 1 can pull the fiberglass cloth 10 to be wound with the mandrel 1. The yarn frame 9 can ensure the tension of the fiberglass cloth 10 during the winding process.

[0032] The fiberglass cloth traction seam 11 is distributed along the length of the outer cylinder 7 and can be processed to be the same length as the core rod 1.

[0033] In this application, the outer cylinder 7 has a cylinder interlayer 13 on its outer wall. The cylinder interlayer 13 can communicate with the drying hole 12. The drying hole 12 includes a drying inlet pipe and a drying outlet pipe. The drying inlet pipe and the drying outlet pipe are respectively connected to the corresponding steam pipes. The drying hole 12 can dry the formed cement mortar by introducing steam, thereby accelerating its forming speed.

[0034] The right frame containing the baffle 6 can adjust its position along the adjusting seat 15 and fix itself relative to the adjusting seat 15 with fasteners, which facilitates the removal of the core rod 1 and its cement shell after molding.

[0035] Although the technical solutions described in this application are based on preferred embodiments, any substitutions and modifications made by those skilled in the art to the technical solutions of this application should be understood as extensions of the technical solutions of this application and still fall within the protection scope of this application.
