Description

Technical Field

[0001] This utility model belongs to the field of PVC pipe fitting production technology, specifically relating to an impact-resistant pipe fitting production equipment. Background Technology

[0002] Polyvinyl chloride alloy pipes are pipe fittings manufactured from PVC alloy materials. PVC alloy materials are composite materials obtained by blending and modifying various resins with PVC as the main component. The word "alloy" here has no relation to metal. PVC alloys are a new type of high-performance, functional, and specialized material obtained through physical blending or chemical grafting methods.

[0003] Domestic utility model patent application number 202221591675.4 discloses a PVC pipe fitting production equipment. This equipment includes a base plate and a screw extrusion device. The screw extrusion device is installed on top of the base plate, and a feed hopper is fixedly connected to the top of the screw extrusion device. The interior of the feed hopper is connected to the interior of the screw extrusion device, and an arc-shaped groove is formed inside the feed hopper. This utility model utilizes an auxiliary mixing rod that revolves around a main mixing rod while rotating on its own axis, thereby thoroughly mixing the raw materials inside the mixing cylinder and ensuring sufficient reaction between the materials. This improves the production quality of PVC pipe fittings. An extension rod blocks agglomerates and foreign matter in the raw materials. Subsequently, the synchronous shaft rotates, causing the extension rod and the crushing rod to work together to crush the agglomerates, preventing blockages. This solves the problems of poor mixing effect and easy blockage of the feed in previous PVC pipe fitting production equipment. While this utility model has the function of screening raw materials and avoiding feed blockages, to produce pipe fittings with high impact resistance, other chemical raw materials must be added to the material; it cannot increase its physical resistance.

[0029] This specific embodiment is an impact-resistant pipe fitting production equipment.

[0030] The above-mentioned utility model has the function of screening raw materials and avoiding the problem of clogging during feeding. However, if you want to produce pipe fittings with strong impact resistance, you can only add other chemical raw materials to the material, but you cannot increase its physical resistance.

[0031] Its structural diagram is as follows Figures 1-4 As shown. An impact-resistant pipe fitting production device includes a melting tank 1 and a production mold frame 2 connected to one end of the melting tank 1. An extrusion tank 4 is welded and installed inside the melting tank 1, and multiple sets of infrared heating rings 5 ​​are fixedly installed between the extrusion tank 4 and the melting tank 1.

A support frame 11 and a base frame 21 are fixedly installed on both sides of the bottom of the melting tank 1, and a fixing frame 13 is fixedly installed on one side of the melting tank 1. The drive motor 3 is fixedly installed on the top of the fixing frame 13, and a feed pipe 12 is installed on the top of the extrusion tank 4, extending through the top of the melting tank 1. Pipe fitting production materials are fed into the extrusion tank 4 through the feed pipe 12 for production.

[0032] The production mold frame 2 has a mold 6 for producing pipe fittings fixedly installed inside, and a heat dissipation box 27 is fixedly installed on one side of the bottom of the production mold frame 2. Four sets of welding frames 23 are fixedly installed at the bottom of the production mold frame 2, and pulleys 24 are fixedly installed at the bottom of the welding frames 23. A track frame 22 is welded to one side of the bottom of the base frame 21. The welding frames 23 are slidably mounted on the top of the track frame 22 via the pulleys 24. The production mold frame 2 is moved by sliding the pulleys 24, and the mold 6 inside the production mold frame 2 is replaced according to the specific size of the pipe fitting. The production mold frame 2 is slidably connected to the melting tank 1 for installation. The top of the extrusion tank 4 is fixedly installed to the melting tank 1 via two sets of mounting frames 41. A fixed plate 14 is welded to one end of the melting tank 1. A positioning plate 29 that is connected to the fixed plate 14 is welded to one end of the production mold frame 2. An installation plate 42 is welded to the inner ring of the fixed plate 14 at one end of the extrusion tank 4. An extrusion port 43 is opened inside the installation plate 42. The fixed plate 14 is installed by docking with the positioning plate 29 to position and fix the melting tank 1 and the production mold 2, ensuring the stability of the production mold 2 during the production process.

[0033] The mold 6 includes an outer module 64, a docking plate 61 welded to one end of the outer module 64 for docking with the mounting plate 42, and an inner module 63 installed inside the outer module 64. The inner module 63 and the outer module 64 are fixedly installed together by multiple sets of connecting rods 62, and a shaping groove 65 is formed between one end of the outer module 64 and the inner module 63. The material extruded from the extrusion port 43 is introduced into the shaping groove 65 formed between the outer module 64 and the inner module 63 for cooling and shaping, achieving the effect of pipe fitting production. Different specifications of molds 6 can be replaced according to the diameter or thickness of the specific pipe fitting, achieving the adjustable size function of the pipe fitting production equipment. One end of the production mold frame 2 has multiple sets of mounting holes 26, and the other end of the outer module 64 is welded with a positioning frame 66 that docks with the mounting holes 26. One end of the production mold frame 2 is provided with a pipe fitting outlet 25 at the position of the mounting holes 26. By using fixing bolts to fix the other end of the mold 6 to the production mold frame 2, the mold 6 is fixed a second time to ensure the stability of the pipe fitting during the production process.

The two sets of fans 7 fixedly installed on the inclined plate 28 provide air cooling for the pipe fittings shaped between the outer module 64 and the inner module 63. Based on the airflow direction, the tail end of the mold 6 is also cooled, achieving a slow cooling effect on the pipe fittings inside the mold 6. This prolongs the residence time of the PVC alloy material during crystallization and extends the crystal growth time, maximizing the formation of large spherulites inside the pipe fittings, thereby increasing the rigidity and hardness of the pipe fittings and improving their impact resistance. A support frame 81 is fixedly installed on one side of the track frame 22, and a conveyor roller 8 is fixedly installed on the top of the support frame 81. The conveyor roller 8 assists in conveying the pipe fittings exiting from the pipe fitting outlet 25, completing the entire automated production process for the pipe fittings.

[0035] Example: Before production, the production mold frame 2 is moved by sliding pulley 24. Different molds 6 of different specifications can be replaced according to the diameter or thickness of the specific pipe fitting. The sliding production mold frame 2 is then connected and installed with the melting tank 1. The pipe fitting production material is fed into the extrusion tank 4 through the feed pipe 12. The material inside the extrusion tank 4 is heated and melted by the infrared heating ring 5. The drive motor 3 drives the threaded guide rod 44 to rotate and extrude the material. The material extruded from the extrusion port 43 is guided into the shaping groove 65 formed between the outer module 64 and the inner module 63 for cooling and shaping. Two sets of fans 7 fixedly installed on the inclined plate 28 provide air cooling for the pipe fitting shaped between the outer module 64 and the inner module 63. The tail end of the mold 6 is also cooled according to the airflow direction. Finally, the pipe fitting exiting from the pipe fitting outlet 25 is assisted by the conveying roller 8, thus completing the entire automated production process for the pipe fitting.
