Description

Technical Field

[0001] The utility model relates to the technical field of winding pipe production, in particular to a municipal drainage winding pipe production machine. Background Art

[0002] Wrapped pipe, also known as spiral-wrap pipe or wound drainage pipe, is a new type of pipe made from high-strength fiber-reinforced materials, spirally wound around a steel or plastic core to form the pipe body. Because its material is highly strong and corrosion-resistant, it can withstand high pressure and harsh environments, extending its service life. Therefore, it is frequently used in municipal drainage systems, such as municipal underground drainage, sewage disposal, and rainwater collection. To improve production efficiency, a production machine is often used in the production of wound pipe. A municipal drainage wound pipe production machine is a specialized piece of equipment used to produce this type of pipe. It typically uses high-density polyethylene (HDPE) as raw material and uses a hot winding process to form the structural wall pipe. This equipment consists of a plastic extruder, a sheath wrapping machine, and a vulcanizing tank. The plastic extruder heats and melts the HDPE raw material and extrudes it through a die into a tubular preform. The use of a production machine automates the production process, reducing reliance on manual labor and improving production safety.

[0003] In the process of producing wound pipes, when the wound pipes are extruded, the raw materials of the wound pipes are usually added to the hopper, and the raw materials are passed through the hopper into the heating barrel to be heated and melted, and then the screw and the die head are cooperated to extrude the wound pipe to complete the production. After the raw materials enter the hopper, they will fall through the bottom of the hopper and enter the barrel. In the existing technology, the raw materials in the hopper are not stirred or unblocked well, so that the raw materials are easily accumulated in the hopper, which will cause the hopper to be blocked, thereby affecting the continuity of the raw material feeding and the continuity of the wound pipe production. Therefore, in order to solve the above problems, a municipal drainage wound pipe production machine is proposed. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The first motor 12, the second motor 23 and the third motor 26 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described here in detail.

[0023] A municipal drainage spiral pipe production machine includes a machine body, which includes a heating barrel 1, a spiral conveying rod 11 movably connected to the inner side of the heating barrel 1, a first motor 12 fixedly mounted on the surface of the heating barrel 1, the spiral conveying rod 11 and the output end of the first motor 12 fixedly connected, a die head 13 provided on the surface of the spiral conveying rod 11, and a hopper 14 fixedly connected to the top of the heating barrel 1. The heating barrel 1 is configured to heat and melt the raw material of the spiral pipe. The operation of the first motor 12 drives the spiral conveying rod 11 to rotate, and the raw material can be extruded through the die head 13 to form a tubular blank, thereby realizing the production of the spiral pipe.

[0024] A feeding mechanism is provided on the surface of the heating barrel 1, which includes a support plate 2, which is fixedly connected to the upper surface of the heating barrel 1, a first fixed block 21 fixedly connected to the surface of the support plate 2, a screw 22 movably connected to the inner side of the support plate 2, a second motor 23 fixedly installed on the top of the support plate 2, a connecting block 24 threadedly connected to the surface of the screw 22, a rotating rod 25 movably connected to the inner side of the connecting block 24, a third motor 26 fixedly installed on the top of the connecting block 24, a stirring rod 27 fixedly connected to the surface of the rotating rod 25, and the stirring rod 27 is driven to rotate by the rotating rod 25. The rotation of the stirring rod 27 can stir the raw material in the hopper 14, thereby preventing the raw material from accumulating in the hopper 14 and causing the hopper 14 to be blocked, thereby facilitating stable feeding of raw materials to ensure continuous production of the winding tube.

[0025] Furthermore, the feeding mechanism also includes a limit block 28, which is fixedly connected to the surface of the connecting block 24. A limit groove 29 is provided on the inner surface of the support plate 2. One end of the limit block 28 is fixedly connected to the connecting block 24, and the other end of the limit block 28 is movably connected to the limit groove 29. Through the cooperation of the limit block 28 and the limit groove 29, the connecting block 24 can be limited, which can prevent the connecting block 24 from being offset under the action of the screw 22, and facilitate the stable lifting and lowering of the rotating rod 25 and the stirring rod 27.

[0026] Furthermore, one end of the screw 22 is movably connected to the first fixed block 21, and the other end of the screw 22 is fixedly connected to the output end of the second motor 23. Through the rotation of the screw 22, the connecting block 24 can be driven to move vertically, and then the rotating rod 25 and the stirring rod 27 can be raised and lowered at the same time during the rotation process, so that the stirring rod 27 can move up and down to achieve the dredging of the bottom of the hopper 14, thereby ensuring the continuous falling of the raw materials.

[0027] Furthermore, the rotating rod 25 and the output end of the third motor 26 are fixedly connected, and the rotating rod 25 and the stirring rod 27 are both movable on the inner side of the hopper 14. The stirring rod 27 is driven to rotate by the rotating rod 25, so that the stirring rod 27 can stir the raw materials at different positions, thereby achieving dredging of the hopper 14.

[0028] Furthermore, a replacement mechanism is provided on the surface of the heating barrel 1, and the replacement mechanism includes a connecting plate 3, which is fixedly connected to the surface of the heating barrel 1, and a threaded rod 31 is movably connected to the inner side of the connecting plate 3, and a moving block 32 is threadedly connected to the surface of the threaded rod 31, and an insert rod 33 is fixedly connected to the surface of the moving block 32, and a second fixed block 34 is fixedly connected to the surface of the die head 13, and a connecting rod 35 is fixedly connected to the surface of the second fixed block 34, and a slot 36 is provided on the surface of the connecting rod 35. By rotating the threaded rod 31, the moving block 32 can drive the insert rod 33 and the slot 36 to be inserted and separated under the action of the threaded rod 31, so that the die head 13 can be fixed and unfixed, thereby facilitating the replacement of the die head 13 and enabling the production of winding tubes of different models and sizes.

[0029] Furthermore, the insertion rods 33 are in two groups and fixedly connected to the moving block 32, the connecting rods 35 are movably connected to the connecting plate 3, and the slots 36 are in four groups and correspondingly connected to the connecting rods 35. By opening the slots 36, when the insertion rods 33 are moved under the action of the moving block 32 and inserted into the inner side of the slots 36, the connecting plate 3 and the connecting rods 35 can be locked, thereby facilitating the installation of the die head 13 on the heating barrel 1.

[0030] Working principle: When in use, the third motor 26 is electrically connected to an external power source, and the staff starts the third motor 26 by pressing a switch. The operation of the third motor 26 drives the rotating rod 25 to rotate, and the stirring rod 27 will rotate accordingly under the action of the rotating rod 25, so as to achieve stirring of the raw materials in the hopper 14. The second motor 23 is electrically connected to an external power source, and the staff starts the second motor 23 by pressing a switch. The operation of the second motor 23 drives the screw 22 to rotate, and the connecting block 24 is limited by the limit block 28 and the limit groove 29, and will move vertically on the surface of the screw 22, so that the limit block 28 can move inside the limit groove 29, and then the connecting block 24 can drive the rotating rod 25 and the stirring rod 27 to rise and fall, so that the stirring rod 27 can stir the raw materials at different positions and can dredge the hopper 14;

[0031] By rotating the threaded rod 31, the moving block 32 will drive the insertion rod 33 to move horizontally under the action of the threaded rod 31, thereby realizing the separation of the insertion rod 33 and the slot 36, and releasing the fixation of the connecting rod 35. Then, the connecting rod 35 is pulled out from the connecting plate 3, and the die head 13 can be removed from the heating barrel 1, and the die head 13 can be replaced; when the die head 13 needs to be installed, the connecting rod 35 is inserted into the inner side of the connecting plate 3, and then the threaded rod 31 is rotated in the opposite direction. The moving block 32 will drive the insertion rod 33 to move under the action of the threaded rod 31 and engage with the slot 36, so that the connecting rod 35 can be fixed, thereby completing the replacement and installation of the die head 13.

[0032] The above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
