Description

Technical Field

[0001] This utility model relates to the field of thermoplastic machine technology, specifically to an extrusion device for a thermoplastic machine. Background Technology

[0002] The extrusion unit of a thermoplastic extruder is an important piece of equipment used in plastic processing. It uses heat and pressure to shape thermoplastic materials (such as polyethylene, polypropylene, polyvinyl chloride, etc.) through a mold. The unit typically consists of a heating section, an extrusion screw, an extrusion die, and a cooling system.

[0003] As disclosed in CN218777000U, a heated extrusion device for an injection molding machine includes a base. A metering feeding mechanism is slidably connected to the top of the base. A heated extrusion tube is installed on one side of the metering feeding mechanism. A heat-conducting coil is wound around the outer surface of the heated extrusion tube. A hopper is installed at the top of the metering feeding mechanism. The air outlet of the heat-conducting coil is connected to a conveying pipe, and the air outlet of the conveying pipe is connected to the hopper. The air inlet of the heat-conducting coil is connected to a return air pipe, and the return air pipe is connected to the hopper. This invention absorbs the heat generated by the heated extrusion tube during operation through the heat-conducting coil. At this time, a fan extracts the hot air from the heat-conducting coil through the conveying pipe and delivers the hot air to the hopper, thereby heating and drying the raw material particles in the hopper. Compared with existing extruders, this invention does not require additional electric heating, but uses the equipment's own heat conduction to dry the raw material, making it more environmentally friendly.

[0004] The thermoplastic machines mentioned in the patent lack lifting and adjustment functions, requiring operators to bend over to operate them. Maintaining this posture for a long time can easily lead to excessive strain on the waist and spine, increasing the risk of waist injury. In addition, these thermoplastic machines generally lack segmented heating functions, resulting in uneven heating and an inability to accurately control the temperature of different parts. This not only affects the plasticizing effect of the plastic, but also leads to unstable finished product quality, increasing energy consumption and scrap rate in the production process. Utility Model Content

[0005] The purpose of this utility model is to provide an extrusion device for a thermoplastic machine, which has a height adjustment function to adapt to the height needs of different workers, and also has the advantage of segmented heating, thus solving the problems mentioned in the background art.

[0021] As attached Figure 1 To be continued Figure 5As shown: This embodiment provides an extrusion device for a thermoplastic machine, including a worktable 1. A first fixed frame 2 is fixedly connected to one side of the top of the worktable 1. A first motor 3 is fixedly connected to the inner cavity of the first fixed frame 2. A screw rod 4 is fixedly connected to the output end of the first motor 3. A first fixed column 5 is fixedly connected to one side of the first fixed frame 2, and the screw rod 4 is disposed in the inner cavity of the first fixed column 5. Two support columns 6 are fixedly connected to one side of the top of the worktable 1. A feeding bin 7 is fixedly connected to the bottom of one end of each of the two support columns 6. Both feeding bins 7 penetrate into the inner cavity of the first fixed column 5 and are fixedly connected to the first fixed column 5. A rotating shaft 8 is rotatably connected to the inner cavity of the feeding bin 7. Sliding columns 9 are fixedly connected to the four corners of the bottom of the worktable 1. A second fixed column 10 is disposed at the bottom of each of the four sliding columns 9, and the sliding columns 9 are slidably connected to the second fixed columns 10. On the surface, the bottom of the four second fixed posts 10 are fixedly connected to a fixed base 11. The top of both sides of the fixed base 11 are fixedly connected to threaded posts 12. The top of the two threaded posts 12 are fixedly connected to a concave block 13. A second fixed frame 14 is fixedly connected to one side of the concave block 13. A second motor 15 is fixedly connected to the inner cavity of the second fixed frame 14. The output end of the second motor 15 passes through the inner cavity of the concave block 13 and is fixedly connected to a rotating rod 16. Both ends of the rotating rod 16 are fixedly connected to a first gear 17. Both sides of the inner cavity of the concave block 13 are rotatably connected to a second gear 18. The first gear 17 and the second gear 18 mesh with each other. A threaded rod 19 is fixedly connected inside the second gear 18. A threaded block 20 is slidably connected to the surface of the threaded rod 19, and both ends of the threaded block 20 are fixedly connected to the inner wall on the opposite side of the sliding post 9.

[0022] Specifically, four support blocks 21 are fixedly connected to the bottom of the first fixed column 5, and the four support blocks 21 are fixedly connected to the top of the workbench 1.

[0023] In this embodiment, the support block 21 effectively provides stable support, thereby preventing the first fixed column 5 from shaking or becoming unstable during use, making it more stable when bearing load, and avoiding unnecessary damage or malfunction caused by shaking.

[0024] Specifically, a first heating ring 22 is fixedly connected to the inner cavity of the middle part of the first fixed post 5, a second heating ring 23 is fixedly connected to the inner cavity of one end of the first fixed post 5, and a heating rod 24 is fixedly connected to the inner cavity of the spiral rod 4.

[0025] In this embodiment, the combined use of the first heating ring 22, the second heating ring 23 and the heating rod 24 enables more uniform and efficient heating of the material, thereby achieving a better melting effect, improving melting efficiency, shortening heating time, effectively avoiding local overheating or underheating, and ensuring uniform temperature distribution of the material throughout the heating process.

[0026] Specifically, the surface of the second fixed frame 14 is provided with heat dissipation holes.

[0027] In this embodiment, the heat generated by the second motor 15 during operation can be effectively discharged through the heat dissipation holes, preventing damage to the second motor 15 or affecting its performance due to overheating, improving the working stability of the second motor 15, extending its service life, and ensuring high efficiency and safety during long-term operation.

[0029] In this embodiment, the combined use of the first fixing block 25 and the second fixing block 26 can significantly enhance the overall stability of the device during the lifting process, avoid tilting or unevenness during operation, thereby improving operational safety and accuracy, and enhancing its applicability and reliability in various working environments.

[0030] The working principle and usage process of this utility model are as follows: The user starts the second motor 15, which drives the rotating rod 16 to rotate. The two ends of the rotating rod 16 are fixedly connected to the first gear 17. The first gear 17 meshes with the second gear 18, thereby driving the second gear 18 to rotate. The second gear 18 is fixedly connected to the threaded rod 19, which in turn causes the threaded block 20 to slide along the surface of the threaded rod 19. The threaded block 20 is fixedly connected to the sliding column 9, which causes the sliding column 9 to move smoothly on the surface of the second fixed column 10, ultimately driving the worktable 1 to rise and fall. After adjusting to a suitable height, the second motor 15 is turned off. Then, the first motor 3 is started. Driven by the first motor 3, it drives the worktable 1 located in the inner cavity of the first fixed column 5. The screw rod 4 rotates, and then the material is poured into the inner cavity of the feeding hopper 7. The feeding hopper 7 is connected to a rotating shaft 8, which is equipped with a spiral structure to ensure that the material can fall smoothly and avoid blockage. Then, the first heating ring 22, the second heating ring 23 and the heating rod 24 are activated to heat and melt the material. The first heating ring 22 is set with a relatively stable and high temperature, which can quickly heat the material and melt it rapidly. Then, the material continues to move forward along the surface of the screw rod 4 and enters the heating chamber in the second heating ring 23. The temperature of the second heating ring 23 is relatively low. Through cooperation with the heating rod 24, it ensures that the material maintains a suitable temperature during the heating process, ensuring the melting effect and thus ensuring the quality of the material.
