Description
Technical Field
[0001] This utility model relates to the field of plastic film technology, and in particular to a mixing machine for raw materials in plastic film production. Background Technology
[0002] In the production process of plastic film, the raw material mixer plays a crucial role. Due to its excellent flexibility and barrier properties, plastic film is widely used in packaging, agriculture, industry, and many other fields. Uniform mixing of raw materials is a key prerequisite for producing high-quality plastic film. This mixing process must be completed in specialized mixing equipment—the raw material mixer for plastic film production. In the plastic film production workshop, the mixer operates continuously, thoroughly mixing various raw materials to provide a stable mix of high-quality raw materials for subsequent plastic film forming and processing.
[0003] Most existing mixing devices for plastic film production employ simple agitator structures. Driven by a motor, the agitator rotates at high speed within the mixing tank, using its blades to tumble and stir the raw materials, blending them together to achieve a mixing effect. However, during the mixing process, raw materials inevitably adhere to the inner wall of the mixing tank. Because existing mixing devices lack tools to scrape the inner wall, this adhered material gradually accumulates over time. This accumulated material affects the uniformity of subsequent batch mixing, leading to variations in product quality between different batches. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a plastic film production raw material mixer, which aims to improve the problem of the lack of internal cleaning devices in the existing technology, resulting in differences in product quality between different batches.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic film production raw material mixer, comprising a housing, an installation block fixedly connected to the lower surface of the housing, a motor fixedly connected inside the installation block, a connecting rod two fixedly connected to the output end of the motor, a stirring plate fixedly connected to the outer wall of the connecting rod two, a rotating disk fixedly connected to the outer wall of the connecting rod two, an installation plate fixedly connected to the outer wall of the rotating disk, a sliding rod slidably connected inside the installation plate, a spring provided on the outer wall of the sliding rod, one end of the spring fixedly connected to the side of the installation plate near the housing, the other end of the spring fixedly connected to a scraper, a connecting plate one fixedly connected to the lower surface of the scraper, the lower surface of the installation plate slidably connected to the upper surface of the connecting plate one, and a sealing assembly provided on the outer wall of the sliding rod.
[0006] Furthermore, the sealing assembly includes a sealing gasket, the outer wall of which is fixedly connected to the mounting plate on the side away from the scraper, and the outer wall of the sliding rod is slidably connected to the inner wall of the sealing gasket.
[0007] Furthermore, a second outer shell is fixedly connected to the upper surface of the first outer shell, a first connecting rod is rotatably connected inside the second outer shell, a handle is fixedly connected to one end of the first connecting rod, a feeding plate is fixedly connected to the outer wall of the handle, and a second connecting plate is fixedly connected to the outer wall of the feeding plate.
[0008] Furthermore, a slide rail is slidably connected to the outer wall of the connecting plate two, a protective cover is fixedly connected to the outer wall of the slide rail, and the outer wall of the protective cover is fixedly connected to the inner wall of the upper outer shell two.
[0009] Furthermore, the outer wall of the connecting plate is slidably connected to the inside of the protective cover, and the outer wall of the feeding plate is slidably connected to the inner wall of the outer shell.
[0010] Furthermore, a bracket is fixedly connected to the outer wall of the mounting block, and the upper end of the bracket is fixedly connected to an outer wall of the outer casing.
[0011] Furthermore, a feed hopper is fixedly connected to the upper surface of the second outer shell.
[0012] Furthermore, a discharge port is provided on one side of the outer casing.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, the scraper is connected to the mounting plate via a sliding rod and a spring. During the stirring process, the motor drives the connecting rod two to rotate, which in turn causes the rotating disk to rotate, and the mounting plate rotates accordingly. At this time, the spring will elastically adjust according to the contact between the scraper and the inner wall of the outer shell, so that the scraper is always in close contact with the inner wall of the mixing tank. This close-fitting scraping method can more effectively remove the raw materials adhering to the inner wall compared with traditional stirring devices, greatly enhancing the cleaning effect, avoiding the impact of raw material residue on the uniformity of subsequent mixing, and ensuring the stability of product quality in different batches.
[0015] 2. In this utility model, precise material feeding is achieved by rotating the feeding plate. When the connecting rod rotates, it drives the handle and the feeding plate to rotate together. The operator can control the opening size of the feeding plate by rotating the handle, thereby precisely controlling the amount of raw materials fed and achieving a more accurate mixing ratio. At the same time, a slide rail is installed inside the protective cover, and the connecting plate slidably connects to the slide rail. During the rotation of the feeding plate, the connecting plate slids along the slide rail. This cooperation makes the rotation of the feeding plate more stable, effectively avoiding shaking or jamming during the feeding process, ensuring the stability and continuity of the feeding, and further improving the accuracy and efficiency of raw material mixing.

[0023] Reference Figure 1 - Figure 3This utility model provides an embodiment of a plastic film production raw material mixer, including a shell 1. A mounting block 6 is fixedly connected to the lower surface of the shell 1. A motor 8 is fixedly connected inside the mounting block 6. A connecting rod 22 is fixedly connected to the output end of the motor 8. A stirring plate 12 is fixedly connected to the outer wall of the connecting rod 22. A rotating disk 9 is fixedly connected to the outer wall of the connecting rod 22. The rotating disk 9 serves as a connection and guide, allowing it to drive the scraper 11 to rotate. A mounting plate 14 is fixedly connected to the outer wall of the rotating disk 9. A sliding rod 13 is slidably connected inside the mounting plate 14. A spring 16 is provided on the outer wall of the sliding rod 13. One end of the spring 16 is fixedly connected to the mounting plate 14 near the outer edge. On one side of shell 1, a scraper 11 is fixedly connected to the other end of spring 16. The scraper 11 can scrape the inner wall of shell 1 to achieve a cleaning effect. A connecting plate 10 is fixedly connected to the lower surface of scraper 11. The lower surface of mounting plate 14 is slidably connected to the upper surface of connecting plate 10. A sealing component is provided on the outer wall of sliding rod 13. The sealing component includes a sealing gasket 15. The outer wall of sealing gasket 15 is fixedly connected to the side of mounting plate 14 away from scraper 11. The outer wall of sliding rod 13 is slidably connected to the inner wall of sealing gasket 15. A bracket 2 is fixedly connected to the outer wall of mounting block 6. The bracket 2 provides support. The upper end of bracket 2 is fixedly connected to the outer wall of shell 1. A discharge port 5 is opened at the bottom of shell 1.
[0024] Specifically, the outer casing 1, as the main load-bearing component of the entire mixer, provides installation space and protection for other internal components. A mounting block 6 is fixedly connected to the lower surface of the outer casing 1, providing stable support for the motor 8. The motor 8 is fixedly connected inside the mounting block 6. The motor 8, through the rotation of its output shaft, drives the connected connecting rod 22 to rotate, thereby driving the stirring plate 12 to stir the raw materials and the scraper 11 to clean the inner wall of the mixer. The output end of the motor 8 is fixedly connected to the connecting rod 22, which transmits the rotational power output by the motor 8 to the stirring plate 12 and the rotating disk 9, enabling the stirring plate 12 to rotate at high speed inside the outer casing 1 to stir and mix the raw materials. It also drives the rotating disk 9 to rotate, providing space for the scraper 11. The cleaning action is powered by the motor 8 and the connecting rod 22. A stirring plate 12 is fixedly connected to the outer wall of the connecting rod 22. The stirring plate 12 is the direct execution component for mixing raw materials. Driven by the motor 8 and the connecting rod 22, the stirring plate 12 rotates at high speed inside the outer shell 1. Through its shape and position design, it turns and stirs the raw materials, so that different types of plastic film production raw materials can be fully mixed to achieve a uniform mixing effect. A rotating disk 9 is fixedly connected to the outer wall of the connecting rod 22. The rotating disk 9 mainly provides the installation position for the mounting plate 14 and drives the mounting plate 14 to rotate around the axis of the connecting rod 22, so that the scraper 11 on the mounting plate 14 can perform a circular cleaning operation on the inner wall of the mixer. The mounting plate 14 is fixedly connected to the outer wall of the rotating disk 9. The mounting plate 14 provides support and guidance for the movement of the scraper 11. A sliding rod 13 is slidably connected inside the mounting plate 14, providing a mounting base for the spring 16 and the scraper 11. A spring 16 is installed on the outer wall of the sliding rod 13, serving as an elastic adjuster. When the scraper 11 rotates with the mounting plate 14 and contacts the inner wall of the mixer, the spring 16 automatically extends and retracts according to the tightness of the contact, ensuring that the scraper 11 remains tightly against the inner wall of the mixer during rotation. This ensures effective scraping of the raw materials adhering to the inner wall, enhancing the cleaning effect. One end of the spring 16 is fixedly connected to the side of the mounting plate 14 near the outer casing 1, and the other end is fixedly connected to the scraper 11. With the cooperation of the spring 16 and the sliding rod 13, the scraper 11 rotates with the mounting plate 14. The scraper 11 continuously scrapes against the inner wall of the mixer, removing raw materials adhering to it. This prevents residue from affecting the uniformity of subsequent mixing and ensures the stability of product quality across different batches. A connecting plate 10 is fixedly connected to the lower surface of the scraper 11. The connecting plate 10 connects and supports the scraper 11, keeping it stable during movement. It also provides a track for the sliding of the mounting plate 14, ensuring that the lower surface of the mounting plate 14 can slide stably on the upper surface of the connecting plate 10. This ensures the smooth cleaning action of the scraper 11. The lower surface of the mounting plate 14 is slidably connected to the upper surface of the connecting plate 10. This sliding connection allows the mounting plate 14 to more flexibly adjust the position of the scraper 11 during rotation.To further improve the fit between the scraper 11 and the inner wall of the mixer and enhance the cleaning effect, a sealing assembly is provided on the outer wall of the sliding rod 13. The sealing assembly includes a sealing gasket 15, the outer wall of which is fixedly connected to the side of the mounting plate 14 away from the scraper 11. The outer wall of the sliding rod 13 is slidably connected to the inner wall of the sealing gasket 15. The main function of the sealing gasket 15 is to prevent raw materials or dust and other impurities inside the mixer from entering the gap between the mounting plate 14 and the sliding rod 13, thus preventing these impurities from affecting the normal sliding of the sliding rod 13 and ensuring that the scraper 11 can perform cleaning smoothly. It also prevents impurities from corroding or damaging components such as the spring 16. To extend the service life of the mixer, a bracket 2 is fixedly connected to the outer wall of the mounting block 6. The upper end of the bracket 2 is fixedly connected to the outer wall of the outer casing 1. The bracket 2 serves to assist in supporting the outer casing 1, sharing the weight of the outer casing 1 and internal components with the mounting block 6. This makes the mixer more stable during placement and operation, preventing it from tipping over due to an unstable center of gravity and ensuring safety during production. A discharge port 5 is located at the bottom of the outer casing 1. The discharge port 5 is used to discharge the mixed raw materials. After the raw materials are evenly mixed, opening the discharge port 5 allows the mixed raw materials to flow out and enter subsequent production stages, thus realizing the production function of the mixer.
[0025] Reference Figure 1 , Figure 2 and Figure 4 A second outer shell 4 is fixedly connected to the upper surface of the outer shell 1. A connecting rod 21 is rotatably connected inside the second outer shell 4. A handle 18 is fixedly connected to one end of the connecting rod 21. The handle 18 allows the operator to easily adjust the opening of the feeding port for precise feeding. A feeding plate 7 is fixedly connected to the outer wall of the handle 18. The rotation angle of the feeding plate 7 can control the feeding rate. A connecting plate 20 is fixedly connected to the outer wall of the feeding plate 7. A slide rail 19 is slidably connected to the outer wall of the connecting plate 20. A protective cover 17 is fixedly connected to the outer wall of the slide rail 19. The outer wall of the protective cover 17 is fixedly connected to the inner wall of the upper outer shell 4. The outer wall of the connecting plate 20 is slidably connected to the inside of the protective cover 17. The outer wall of the feeding plate 7 is slidably connected to the inner wall of the second outer shell 4. A feed hopper 3 is fixedly connected to the upper surface of the second outer shell 4. The feed hopper 3 facilitates the feeding of raw materials.
[0026] Specifically, a second outer shell 4 is fixedly connected to the upper surface of the outer shell 1. The second outer shell 4 is mainly used to expand the functional area of the mixer. The second outer shell 4 can provide a certain degree of protection for the interior and reduce the interference of external factors on the internal operation. A connecting rod 21 is rotatably connected inside the second outer shell 4. One end of the connecting rod 21 is connected to the handle 18, and the other end rotates inside the second outer shell 4. Its main function is to convert the rotation of the handle 18 into the rotation of the feeding plate 7, realize the control of the feeding action, and ensure that the feeding plate 7 can rotate stably to ensure the smooth feeding process. The handle 18 is fixedly connected to one end of the connecting rod 21. The handle 18 provides a force point for the operator. By rotating the handle 18, the operator can easily drive the connecting rod 21. The discharge plate 7 rotates, thereby controlling the opening size of the discharge plate 7 to achieve precise control of the raw material discharge amount, making the raw material mixing ratio more accurate. The discharge plate 7 is fixedly connected to the outer wall of the handle 18. The discharge plate 7 is a key component for controlling the raw material discharge. Driven by the handle 18 and the connecting rod 21, the discharge plate 7 rotates. By adjusting its relative position with the inner wall of the outer casing 4, the size of the discharge opening is changed, thereby precisely controlling the amount of raw material entering the mixer from the feed hopper 3, ensuring that different raw materials enter the mixing area according to the set ratio, and improving the mixing accuracy. The outer wall of the discharge plate 7 is fixedly connected to the connecting plate 20. The connecting plate 20 enhances the structural stability of the discharge plate 7, making it more secure during rotation. The sliding connection includes a slide rail 19, which provides a track for the sliding of the connecting plate 20. When the connecting plate 20 rotates with the feeding plate 7, it slides along the slide rail 19. This effectively limits the movement trajectory of the connecting plate 20, making the rotation of the feeding plate 7 more stable and smooth, preventing jamming during feeding, and improving feeding accuracy and efficiency. A protective cover 17 is fixedly connected to the outer wall of the slide rail 19. The protective cover 17 mainly serves a protective function, preventing external dust, impurities, etc., from entering the mating area between the slide rail 19 and the connecting plate 20, avoiding these impurities from affecting the sliding of the connecting plate 20, and ensuring that the feeding plate 7 can rotate normally. At the same time, the protective cover 17 provides a certain degree of protection for the interior, ensuring production. To ensure safety during the production process, the outer wall of the protective cover 17 is fixedly connected to the inner wall of the upper outer shell 4. This connection method makes the protective cover 17 and the outer shell 4 form a whole, enhancing the stability of the structure. The outer wall of the connecting plate 20 is slidably connected inside the protective cover 17. This design further ensures the stability and accuracy of the connecting plate 20 during the sliding process. The inner wall of the protective cover 17 plays a certain limiting and guiding role for the connecting plate 20, allowing the connecting plate 20 to slide more stably along the slide rail 19, thereby ensuring smoother rotation of the unloading plate 7 and improving the reliability of the unloading operation. The outer wall of the unloading plate 7 is slidably connected to the inner wall of the outer shell 4. This connection method allows the unloading plate 7 to fit tightly against the inner wall of the outer shell 4 during rotation.The feeding amount is precisely controlled by adjusting the relative position between the two, while also preventing leakage of raw materials during the falling process. This ensures that the raw materials can smoothly enter the mixing area from the feed hopper 3 through the discharge plate 7, improving the efficiency and quality of raw material mixing. The feed hopper 3 is fixedly connected to the upper surface of the outer shell 4. The feed hopper 3 is the inlet for raw materials to enter the mixer. The design of the feed hopper 3 makes it convenient for operators to pour various plastic film production raw materials into the mixer, and its shape and structure guide the raw materials to flow smoothly downwards into the discharge area controlled by the discharge plate 7, providing a source of raw materials for subsequent mixing operations.
[0027] Working Principle: The operator turns handle 18, which drives the connecting rod 21 fixedly connected to it to rotate. The rotation of connecting rod 21 causes the feeding plate 7 to rotate synchronously. By adjusting the relative position of the feeding plate 7 and the inner wall of the outer shell 4, the size of the feeding opening is changed. At this time, the plastic film production raw materials located in the feed hopper 3 enter the mixer through the opening controlled by the feeding plate 7 under the action of gravity. During this process, the connecting plate 20 and the slide rail 19 cooperate to ensure the stable rotation of the feeding plate 7, avoid shaking and jamming, achieve precise feeding, and ensure that different raw materials enter the mixing area in the set proportion. The motor 8 in the mounting block 6 starts, and the rotation of the output end of the motor 8 drives the connecting rod 22 to rotate. The connecting rod 22 transmits power to the mixing plate 12. The mixing plate 12 rotates at high speed in the outer shell 11. With its special shape and position design, it turns and stirs the various raw materials that enter, so that different kinds of plastic film production raw materials are fully mixed and achieve a uniform mixing effect, laying the foundation for the subsequent production of high-quality plastic film. As 2 rotates, the rotating disk 9 also rotates, which in turn drives the mounting plate 14 to rotate around the axis of the connecting rod 22. A spring 16 is provided on the sliding rod 13 slidably connected inside the mounting plate 14. One end of the spring 16 is connected to the mounting plate 14, and the other end is connected to the scraper 11. When the mounting plate 14 rotates, the scraper 11 rotates accordingly and contacts the inner wall of the outer casing 1. The spring 16 will automatically extend and retract according to the contact between the scraper 11 and the inner wall, ensuring that the scraper 11 is always in close contact with the inner wall, continuously scraping the material adhering to the inner wall and scraping it off. To avoid raw material residue affecting the uniformity of subsequent mixing and to ensure the stability of product quality across different batches, the sealing gasket 15 prevents raw materials or dust and other impurities from entering the gap between the mounting plate 14 and the sliding rod 13, ensuring the smooth cleaning action of the scraper 11 and protecting internal components from corrosion by impurities. After the raw materials are mixed, the discharge port 5 located below the outer casing 1 is opened, and the uniformly mixed raw materials flow out from the discharge port 5 under the action of gravity and enter the subsequent production process, thus completing the production function of the mixer.
