Description

Technical Field

[0001] This utility model relates to the field of stirring technology, and in particular to a stirring device for injection molding melting. Background Technology

[0002] A mixing device is a piece of equipment used in industrial production to thoroughly and uniformly mix various materials. In the field of plastics processing, it uses mechanical motion to mix plastic raw materials in a specific container, and then heats them to melt them, so as to achieve uniform mixing and lay the foundation for subsequent processes such as injection molding. Its structure and performance directly affect the quality of plastic products and production efficiency.

[0003] When melting and stirring plastic raw materials, there are many types of plastic raw materials. Different types of plastics have different melting points, thermal stability and fluidity. For example, some engineering plastics have high melting points and large viscosity changes during the melting process. This requires the stirring device to provide sufficient stirring power. At the same time, it is also necessary to prevent local overheating from causing plastic decomposition during the stirring process to ensure that the raw materials are fully melted.

[0004] Conventional mixing devices achieve mixing through simple blade rotation, which can mix common plastic raw materials to a certain extent. However, due to the simple blade structure and fixed mixing mode, they are not very adaptable to complex plastic raw material systems. When dealing with plastics with high melting points and low fluidity, the blades can only rotate in a single plane or within a limited angle range, which cannot form a multi-dimensional mixing flow field. This results in dead zones in the plastic within the tank, where the raw materials cannot be fully agitated and heated, leading to incomplete melting and uneven mixing. Ultimately, this affects the quality stability and mechanical properties of injection molded products. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a stirring device for injection molding melting, which aims to improve the problem that the existing technology has poor adaptability to complex plastic raw material systems due to the single blade structure and fixed stirring mode, resulting in incomplete plastic melting and uneven mixing, which ultimately affects the quality stability and mechanical properties of injection molded products.

An I-shaped slider is fixedly connected to the far end of each of the multiple connecting rods. Limiting grooves are provided at the top and bottom of the multiple I-shaped sliders. The multiple I-shaped sliders are slidably connected inside the T-shaped groove.

[0009] As a further description of the above technical solution:

[0032] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a stirring device for injection molding melting, comprising a tank 1. A feeding port 2 is provided on the upper left side of the tank 1 for convenient input of plastic raw materials. A stirring motor 3 is fixedly installed at the bottom of the tank 1, providing power to drive subsequent stirring components. The output end of the stirring motor 3 passes through the bottom of the tank 1 and is fixedly connected to an auger 4. The auger 4 can convey the raw materials upwards and coordinate stirring. A mounting frame 5 is fixedly connected to the top of the auger 4, used for fixing other stirring components. Multiple stirring blades 6 are fixedly installed inside the mounting frame 5, which can fully stir and mix the raw materials. The top of the mounting frame 5 is fixedly... A conical block 7 is connected, which serves to stabilize the structure and provide connection. Multiple heating plates 8 are fixedly and equidistantly connected around the interior of the tank 1. The heating plates 8 heat and melt the raw materials inside the tank. An inclined groove 9 is provided on the right side of the bottom of the tank 1 to facilitate the flow of molten plastic to the discharge pipe 21. A rotational stabilizing mechanism is provided in the upper part of the inner wall of the tank 1. The rotational stabilizing mechanism includes a T-shaped slide 10, which is located in the upper part of the inner wall of the tank 1. Multiple connecting rods 11 are fixedly and equidistantly connected to the outside of the conical block 7. The fixing positions of the multiple connecting rods 11 are triangular structures. I-beam sliders 12 are fixedly connected to the farthest ends of the multiple connecting rods 11. Limiting grooves 13 are provided at both the top and bottom of the tank. Multiple I-beam sliders 12 are slidably connected inside the T-shaped slide groove 10. This rotational stabilization mechanism can effectively prevent the stirring motor 3 from shaking or shifting due to the rotation of components such as the auger 4 and mounting bracket 5 during operation, ensuring the stability of the entire stirring device structure. A feeding and sealing mechanism is provided on the left side of the tank body 1. The feeding and sealing mechanism includes an arc-shaped feeding hopper 14, which is fixedly connected to the upper middle part of the left side of the tank body 1. Two hinges 15 are fixedly connected to the top of the arc-shaped feeding hopper 14. A sealing cover 16 is fixedly connected to the left end of each of the two hinges 15.

A fixing buckle 18 is fixedly connected to the left end, and the pressing buckle 17 engages with the fixing buckle 18. A sealing groove 19 is opened on the top left side of the arc-shaped feeding hopper 14. A sealing strip 20 is fixedly connected to the bottom of the sealing cover 16. The sealing groove 19 and the sealing strip 20 are engaged. The feeding sealing mechanism can effectively prevent the odor from the feeding port 2 from overflowing after the plastic melts, ensuring a good working environment. A discharge pipe 21 is connected to the bottom right side of the tank body 1. The discharge pipe 21 is used to discharge the molten plastic. A solenoid valve 22 is fixedly installed in the middle of the discharge pipe 21. The solenoid valve 22 can control the opening and closing of the discharge.

[0033] Reference Figure 2 and Figure 4The feeding and sealing mechanism includes an arc-shaped feeding hopper 14, which is fixedly connected to the upper left side of the tank body 1. It provides a guiding channel for raw material input, facilitating accurate introduction of plastic raw materials into the tank body 1. Two hinges 15 are fixedly connected to the top of the arc-shaped feeding hopper 14, allowing the sealing cover 16 to rotate flexibly relative to the arc-shaped feeding hopper 14, enabling opening and closing operations. Sealing covers 16 are fixedly connected to the left ends of both hinges 15. When closed, the sealing cover 16 blocks the feeding port 2, preventing material and odor leakage. A pressing mechanism is fixedly connected to the left end of the arc-shaped feeding hopper 14. The buckle 17 engages with the fixing buckle 18 fixedly connected to the left end of the sealing cover 16.

The tight cooperation between the two further enhances the sealing effect, which can effectively prevent the odor from the feeding port 2 after the plastic melts, protect the air quality of the working environment, and reduce potential threats to the health of operators and pollution to the surrounding environment.

[0034] Reference Figure 1 and Figure 2 A fixing ring 24 is fixedly connected to the lower part of the outer wall of the tank body 1. The fixing ring 24 is used to connect the supporting components, which makes the entire device structure more stable. Multiple support legs 25 are fixedly connected at equal intervals around the outer perimeter of the fixing ring 24. The support legs 25 provide a stable support foundation for the device, ensuring that the device remains stable during operation. Anti-slip pads 26 are fixedly connected to the bottom of each support leg 25. The bottom of the anti-slip pads 26 are designed to be anti-slip, which can effectively increase the friction with the ground and prevent the device from shifting due to vibration or other reasons during operation. The fixing ring 24... An operating platform 27 is fixedly connected to the front side. The operating platform 27 is electrically connected to the stirring motor 3, the heating plate 8, and the solenoid valve 22. The operating platform 27 allows the operator to centrally control the operation of the stirring motor 3, the heating of the heating plate 8, and the opening and closing of the solenoid valve 22, improving the convenience and accuracy of operation. A thermometer 28 is fixedly connected to the front side of the tank body 1. The thermometer 28 is electrically connected to multiple heating plates 8. The thermometer 28 can display the temperature inside the tank in real time, allowing the operator to accurately adjust the heating power of the heating plate 8 according to the needs, so as to ensure that the plastic melting process is carried out under suitable temperature conditions.

[0035] Working principle: When the stirring motor 3 is started, the output end of the stirring motor 3 drives the auger 4 to rotate. During the rotation of the auger 4, on the one hand, it can convey the plastic raw material added into the tank 1 from the feeding port 2 upwards, and on the other hand, it works with the mounting frame 5 fixedly connected to its top and the multiple stirring blades 6 inside the mounting frame 5 to stir and mix the plastic raw material. The conical block 7 at the top of the mounting frame 5 rotates together with the auger 4. The multiple connecting rods 11 fixedly connected at equal intervals to the outside of the conical block 7 and the I-shaped sliders 12 at the far end of the connecting rods 11 slide in the T-shaped groove 10 opened in the upper part of the inner wall of the tank 1. Since the top and bottom of the multiple I-shaped sliders 12 are provided with limit grooves 13 and slide in the T-shaped groove 10, it can effectively prevent the stirring motor from moving. When machine 3 is working, it shakes or shifts due to the rotation of auger 4 and mounting frame 5, ensuring the stability of the entire mixing device structure. During the mixing process, multiple heating plates 8, which are fixedly connected at equal intervals around the inside of tank 1, start working to heat the plastic raw material in tank 1 and gradually melt it. The inclined groove 9 on the right side of the bottom of tank 1 helps the molten plastic to flow towards the discharge pipe 21 under the action of gravity. When discharge is required, the solenoid valve 22 in the middle of the discharge pipe 21 is opened, and the molten plastic can flow out through the discharge pipe 21. The flange 23 at the right end of the discharge pipe 21 is convenient to connect to external pipes or containers, which can efficiently complete the plastic injection melting and mixing and discharge process, improving the quality and efficiency of plastic processing.

[0036] Furthermore, when adding material into the tank 1, pressing the snap fastener 17 separates it from the fixing buckle 18. At this time, the sealing cover 16 can be flipped upwards using the two hinges 15 as axes, thus fully opening the feeding port 2 at the top of the arc-shaped feeding hopper 14. Then, the plastic raw material is poured from the arc-shaped feeding hopper 14 into the tank 1, completing the feeding operation. After feeding, the sealing cover 16 is rotated downwards along the hinges 15, so that the sealing cover 16 covers the top of the arc-shaped feeding hopper 14. The sealing strip 20 at the bottom of the sealing cover 16 gradually approaches the sealing groove 19 opened on the left side of the top of the arc-shaped feeding hopper 14. As the sealing cover 16 is fully closed, The sealing strip 20 and the sealing groove 19 are tightly engaged to form a sealing line, which effectively prevents the odor generated by the plastic during the melting process from leaking from the feeding port 2. The fixing buckle 18 at the left end of the sealing cover 16 and the pressing buckle 17 at the left end of the arc-shaped feeding hopper 14 are mutually engaged to further fix the position of the sealing cover 16 and enhance the stability of the seal. This allows for easy opening and closing during feeding, and reliable sealing of the feeding port 2 when closed. This avoids environmental pollution caused by odor leakage and potential health hazards to operators, ensuring the environmental protection and safety of the entire injection molding melting and stirring device during operation.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
